Technical field

The present invention relates to the field of communications technologies, and in particular, to a network resource control method, apparatus, and system. Background technique

With the development of communication technologies, how to improve the utilization of network resources and reduce energy consumption has gradually become a concern of people.

In the prior art, each base station mainly allocates and schedules resources to its own users, and its scheduling generally adopts a strategy of best effort service, that is, the resource scheduling and allocation of the technology is aimed at maximizing capacity. . For example, the specific steps of the program can be as follows:

Sl, the service arrives at the respective base station queue;

Each user has a queue waiting to be scheduled. When the service arrives at the queue of the respective base station, the service packet enters the queue and waits for scheduling. The delay information of the service and the queue buffer are controlled by the scheduler of the base station.

S2. Each base station independently performs resource allocation and scheduling.

After entering each transmission time interval (TTI, Transmission Time Interval), the scheduler sequentially calculates the user according to the service type of the service queue, the traffic volume of the buffer area, the quality of service (QoS) requirements, and the delay information. The priority on the resource block (RB, Resource Block), and then assign the RB to the user with the highest priority.

BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiments of the present invention provide a network resource control method, apparatus, and system. The following is a detailed description. Embodiment 1

In this embodiment, it will be described from the perspective of a gateway device, which may be specifically a device such as a service gateway (S-GW, Serving Gate Way).

A network resource control method includes: receiving a service flow between a core network and a base station, where the service flow carries service information; acquiring load information reported by the base station, and randomly acquiring the service flow according to the service information and the load information Performing a leaked bucket shaping to obtain a shaped service flow; establishing a user queue for the shaped service flow, determining whether the storage resource required by the user queue exceeds a preset first threshold; if yes, from the basic storage resource and the shared storage The storage resource is allocated to the user queue in the resource; if not, the storage resource is allocated to the user queue from the basic storage resource; and the shaped service flow is processed by using the allocated storage resource.

As shown in Figure la, the specific process can be as follows:

101. Receive a service flow between a core network and a base station.

The service flow carries the service information. For example, the service information may include a service generation time, a service data volume, and a service quality of service (Quality of Service) parameter. The quantity parameter may include parameters such as a service allowed delay and a minimum guaranteed rate.

102. Obtain load information reported by the base station.

The load information may be periodically reported by each base station, and the load information may include a service departure rate, a cache data accumulation status, and a time delay.

The load information may further include the resource allocation information of the base station, where the resource allocation information may include the allocation of the resource blocks in the cell and the total rate obtained by the adjusted user. For details, refer to the second embodiment.

103. Perform a leak bucket shaping on the service flow (randomly reached service flow) according to the service information obtained in step 101 and the load information obtained in step 102, to obtain a shaped service flow;

The leaking buckets of different depths can be set to different users to implement the shaping of the arriving traffic flow. Through such shaping, the burstiness of the service can be smoothed and the service smoothness can be ensured. The depth of the leaky bucket depends on the value of the shaping parameter, and the shaping parameter can be adjusted according to the service information and the load information of the base station, that is, the step 103 can be specifically as follows:

According to the service information and the load information, the shaping parameter is adjusted by using the network calculus principle, and then the transmission rate of the service flow is shaped according to the adjusted shaping parameter to obtain the shaped service flow.

104. Establish a user queue for the shaped service flow.

When a user accesses a base station and a service is required, a FIFO (First In First Out) queue may be established in the basic storage space (Basic Buffer) corresponding to the service type according to the service type, which is implemented in the present invention. In the example, the first-in first-out queue is called a user queue, and the space occupied by the user queue in the basic storage space is called a user block.

It should be noted that, in the embodiment of the present invention, as shown in FIG. 1B, the gateway device uses a semi-dynamic manner to share the storage space, that is, the storage space of the gateway device may be divided into two parts, and the part is the basic storage space allocated to the base station. The shared memory is shared by the base station. The basic storage space is also called the basic storage resource. The shared storage space is also called the shared storage resource. Specifically, the size of the basic storage resource corresponding to each base station in the gateway device may be set according to the actual configuration and the service capacity of each base station, where the basic storage resource is only used by the corresponding base station; and the shared storage resource is at each base station. If there is a need, for example, when the basic storage resource is insufficient for use by the base station, it is provided to the base station, and the storage resource allocated to the base station from the shared storage resource is called a shared block of the base station, and the shared block is used. When it is owned by the base station, it cannot be repeated use. A base station can apply for multiple shared blocks at the same time to meet its storage needs. The size of the shared block can be determined according to the actual configuration and service capacity of the base station. Each base station has the right to request allocation of storage resources to the shared storage resource.

For example, as shown in FIG. 1b, the basic storage resource corresponding to the base station 1 is the basic storage space 1, the basic storage resource corresponding to the base station 2 is the basic storage space, and the basic storage resource corresponding to the base station 3 is the basic storage space 3. The base station n The corresponding basic storage resource is the basic storage space n, and the like, and when the basic storage space is insufficient for the base station to use, the storage resource may be allocated from the shared storage space, for example, the base station 1 applies from the shared storage space. The storage resource is the shared block 2, and the storage resource applied by the base station n from the shared storage space is the shared block 1, and so on, and details are not described herein again.

105. Determine whether the storage resource required by the user queue exceeds a preset first threshold. If yes, go to step 106. If no, go to step 107.

The first threshold may be set according to the requirements of the actual application.

106. When the storage resource required by the user queue exceeds a preset first threshold, the storage resource is allocated to the user queue from the basic storage resource and the shared storage resource.

When the storage resource required by the user queue exceeds the preset first threshold, it indicates that the basic storage empty resource corresponding to the base station is insufficient for the user to use for the queue. Therefore, the shared storage needs to be performed at this time. The resource requests storage resources to ensure that the user queue can be allocated enough storage space, that is, at this time, the storage resources required by the user queue include user blocks and shared blocks.

107. When the storage resource required by the user queue does not exceed a preset first threshold, allocate a storage resource for the user queue from the basic storage resource.

When the storage resource required by the user queue does not exceed the preset first threshold, it indicates that the basic storage empty resource corresponding to the base station is sufficient for the user to use the queue. Therefore, the sharing is not required at this time. The storage resource requests storage resources, that is, at this time, the storage resources required by the user queue include user blocks.

108. Process the shaped service flow by using the allocated storage resource, for example, sending the shaped service flow to the base station device according to the user priority, and the like.

Optionally, in order to improve the quality of service, before the shaped service flow is processed by using the allocated storage resource, the sending rate of the shaped service flow may be adjusted, as follows:

Obtain the service curve of the network calculus, the user priority of the user in the cell, and the buffer data. Accumulation status information, service delay requirement information, and quality of service (QoS) information; user priority, buffer area data accumulation status information, and service delay requirements of the user in the cell according to the service curve of the network calculus The information is adjusted to adjust the sending rate of the shaped service flow, so that the sending rate of the shaped service flow satisfies the quality of service information.

In addition, if the base station occupies the shared block (that is, the storage resource occupied by the user queue is allocated by the gateway from the basic storage resource and the shared storage resource), after the base station is used, the occupied shared block is also needed. The network resource control method may further include: after the step of "processing the shaped service flow by using the allocated storage resource", the network resource control method may further include:

The shared storage resource allocated to the user queue is translated.

Similarly, when the user moves out of the service area of the base station, the basic storage resources allocated to the corresponding user queue can also be translated for use by other users, that is, in the step of "processing the shaped service flow with the allocated storage resources". After that, the network resource control method may further include:

When the user moves out of the service area of the base station, the basic storage resources allocated to the user queue are translated.

Optionally, in order to further reduce unnecessary energy consumption of the network resource, the storage resource corresponding to the base station whose traffic is less than the set value may be shut down, and when the wakeup information about the base station is received, the device wakes up. The storage resource corresponding to the base station. That is, the network resource control method may further include:

Determining whether the base station is in the sleep mode; if yes, waking up the basic storage resource corresponding to the base station when determining that the wake-up information of the base station is received; if not, sending the sleep to the base station when determining that the base station reaches the sleep condition The instruction, the sleep instruction instructs the base station to enter a sleep mode, and shuts down a basic storage resource corresponding to the base station.

Whether the base station enters the sleep mode and whether it is awakened or not can be controlled by the gateway, and may be determined by the base station itself. If the base station itself determines, the base station needs to notify the user to enter the sleep mode or wake up. Giving the gateway to the gateway for subsequent operations, for example, if it is known that the base station enters the sleep mode, the basic storage resource corresponding to the base station is turned off, and when it is determined that the wake-up information of the base station is received, the basic storage corresponding to the base station is awake Resources.

It can be seen that, in this embodiment, the service flow between the receiving core network and the base station is used, and the load information reported by the base station is obtained, and then the service flow is carried according to the service flow carrying the service information and the load information. The service flow that the machine arrives is subjected to the leaky bucket shaping to obtain the shaped service flow, and a user queue is established for the shaped service flow. When it is determined that the storage resource required by the user queue exceeds the preset first threshold, the basic storage is obtained. The storage resource is allocated to the user queue in the resource and the shared storage resource. Otherwise, the storage resource is allocated to the user queue from the basic storage resource, and finally the processed service flow is processed by using the allocated storage resource. In this solution, the service flow may be leak-buffered, and the storage resources may be allocated flexibly according to actual requirements. For example, if the user resource corresponding to the service flow needs to occupy the storage resource does not exceed the preset first The threshold value is allocated to the basic storage resource corresponding to the user queue, and if the first threshold is exceeded, the storage resource may be allocated from the basic storage resource corresponding to the user queue. The storage resource can be applied from the shared storage resource, so that the problem that the storage resource caused by the allocation of the storage resource by the maximum amount of traffic is wasted in the prior art, and the storage space in the prior art is always in the working state is avoided. The problem of unnecessary waste of energy can not only save network resources, but also reduce energy consumption. Embodiment 2

In this embodiment, it will be described from the perspective of a base station, which may be an evolved base station (eNodeB, Evolved Node B) or the like.

As shown in Figure 2, the specific process can be as follows:

201. Allocate resource blocks for each user in the cell according to the requirement of each user service information, and calculate interference from neighboring cells on each resource block in each cell;

Before allocating resource blocks for each user in the cell (ie, step 201), the resource blocks that can be used in each cell may be initialized first, and equal power allocation is performed on the resource blocks, that is, in the cell. Before each user allocates a resource block, the method may further include:

Initializing resource blocks that can be used in each cell; performing equal power allocation on the resource blocks. In addition, traffic flows from the gateway device may also be received before resource blocks are allocated to individual users within the cell.

202. Calculate, according to the allocated resource block and the interference, a total rate obtained by each user in the cell. For example, the total rate obtained by each user in the cell may be calculated by using the Shannon formula according to the allocated resource block and the interference.

203. The iterative algorithm is used to adjust the total rate obtained by the user, so that the total rate obtained by the user satisfies the minimum service rate, minimizes the power of the cell, and reduces interference to other cells; for example, the following may be specifically:

If the minimum user service rate requirement is met, the current cell power is calculated. When determining that the current cell power is greater than or equal to the preset cell maximum power, the user that consumes the most power of the cell is rejected, and the total rate of the rejected user is decreased; When the current cell power is less than the preset cell maximum power, the number of iterations is updated, and when it is determined that the current iteration number exceeds the maximum number of iterations, or the cell allocation result has converged, the step of transmitting resource allocation information to the gateway device is performed (ie, step 204) If the current iteration number does not exceed the maximum number of iterations and the cell allocation result has not converged, return to the step of performing a determination of whether the total rate obtained by the user satisfies the minimum service rate requirement of the user;

204. Send resource allocation information to the gateway device.

The resource allocation information may include information such as an allocation of resource blocks in the cell and an adjusted total rate obtained by the user.

In this way, after receiving the resource allocation information, the gateway can further control the network resource according to the resource allocation information. For example, refer to the first embodiment, and details are not described herein again.

Optionally, in order to avoid waste of network resources and reduce power consumption, the network resource control method may further include: after the step of “sending resource allocation information to the gateway device”, the network resource control method may further include:

The second threshold may be set according to requirements of an actual application. As can be seen from the above, in this embodiment, resource blocks are allocated for each user in the cell according to the requirements of each user service information, and interference from neighboring cells on each resource block in each cell is calculated, and the resource block and interference are calculated according to the allocated resources. The total rate obtained by each user in the small area, and the iterative algorithm is used to adjust the total rate obtained by the user, so that the total rate obtained by the user satisfies the minimum service rate while minimizing the power of the cell and reducing interference to other cells. Finally, the resource allocation result is provided to the gateway device. Since the scheme calculates the total rate obtained by the user, not only the resource blocks to which the user is allocated but also the interference from the neighboring cells on each resource block are considered, and the total rate can also be utilized by using an iterative algorithm. The adaptive adjustment is performed so that the total rate obtained by the user can minimize the power of the cell and reduce the interference to other cells while satisfying the minimum service rate, so that not only the flexibility of resource scheduling but also the energy consumption can be reduced. waste.

It should be noted that the network resource control method provided by the embodiment of the present invention may be implemented independently of the network resource control method provided in the first embodiment, or may be implemented by combining the network resource control method provided in the first embodiment. . The methods described in the first and second embodiments will be exemplified in further detail in the third, fourth and fifth embodiments, respectively. Embodiment 3

In this embodiment, the gateway device can set different sizes of leaky buckets for different users to implement shaping of the service flow, and store the shaped service flow into the optimized storage space, and then design and shape using the network calculus principle. After the departure curve of the service flow, and through the information exchange with the base station, coordinate control traffic rate of the service flow, cell sleep state and the corresponding storage space is turned off or on, in order to achieve the purpose of controlling the overall energy consumption of the network, the following Detailed instructions are given.

As shown in FIG. 3a, the gateway device may include a service shaping module, a storage resource control energy saving module, a quality of service control module, and a shutdown control module, as follows:

(1) a service shaping module;

In the service shaping module, the gateway device sets an shaping leak bucket for each user. After the service flow reaches the gateway device, the gateway device inputs the service flow into the leaky bucket to perform shaping to smooth the burstiness of the service and ensure smooth service. Then, the obtained shaped traffic is input into the storage resource control energy-saving module to cooperate with the lower-layer service quality control and energy-saving scheduling algorithm.

(2) Storage resource control energy saving module; After receiving the shaped service flow sent by the service shaping module, the storage resource control energy saving module establishes a user queue for the shaped service flow, wherein the storage resource (ie, the queue space) required by the user queue may be based on the user's The service type is set, and then the storage resource is allocated according to the storage resource that the user queue needs to occupy. For example, it may be determined whether the storage resource required by the user queue exceeds a preset first threshold, and if so, the basic storage resource The storage resource is allocated to the user queue in the shared storage resource. If not, the storage resource is allocated to the user queue from the basic storage resource, so that the complexity of the memory planning can be simplified, and the waste of resources can be reduced.

The storage space of the gateway device may be divided into a basic storage space and a shared storage space, where the basic storage space is also referred to as a basic storage resource, and the shared storage space is also referred to as a shared storage resource. For details, refer to the description in the first embodiment. I will not repeat them here.

(3) Service quality control module;

In order to improve the quality of service, statistics can also be performed on the cell attribution of each user, and the user priority of the users in the cell is obtained, and then the current quality of the user is determined by the service quality control module according to the buffer data accumulation status and the service delay requirement. After the shaping, the transmission rate of the service flow is adjusted, so that the transmission rate can meet the service quality requirement, and the transmission power can be appropriately reduced, and the power consumption of the power amplifier can be reduced.

(4) shutting down the control module;

The shutdown control module is configured to determine whether the base station is in a sleep mode; if yes, when waking up to receive the wakeup information of the base station, waking up the basic storage resource corresponding to the base station; if not, determining that the base station reaches the sleep condition And sending a sleep instruction to the base station, the sleep instruction instructing the base station to enter a sleep mode, and shutting down a basic storage resource corresponding to the base station.

Based on the structure of the foregoing gateway device, as shown in FIG. 3b, the specific process may be as follows:

301. The gateway device divides the storage space of the gateway device, and sets the size of the basic storage resource and the shared storage resource according to the actual configuration and service capacity of each base station.

302. When a user from the core network accesses the base station and has a service, the service shaping module of the gateway device receives the service flow between the core network and the base station, and obtains load information reported by the base station.

The service flow carries service information, and the service information may include a service generation time, a service data volume, and a service quality parameter. The service quality parameter may include a service allowable delay and a minimum guaranteed rate. The load information of the base station can be reported periodically by each base station. The load information may include a service departure rate, a buffer data accumulation status, and a time delay.

303. The service shaping module adjusts the shaping parameter by using the network calculus principle according to the service information and the load information, and then shapes the service flow sending rate according to the adjusted shaping parameter to obtain the shaped service flow.

The storage resource control energy-saving module establishes a user queue for the shaped service flow in the basic storage space corresponding to the gateway device according to the service type, where the space occupied by the user queue in the basic storage space is called a user block.

305. The storage resource control energy-saving module determines whether the storage resource required by the user queue exceeds a preset first threshold. If yes, step 306 is performed, and if no, step 307 is performed.

306. When the storage resource required by the user queue exceeds a preset first threshold, the storage resource control energy saving module allocates storage resources for the user queue from the basic storage resource and the shared storage resource, where: 3⁄4:

If the basic storage resource corresponding to the base station is insufficient for use by the user queue, the shared storage resource may be applied for use by the base station, and the storage resource allocated to the base station from the shared storage resource is referred to as a shared block of the base station. When the shared block is owned by the base station, it cannot be reused. A base station can apply for multiple shared blocks at the same time to meet its storage needs. The size of the shared block can be determined according to the actual configuration and service capacity of the base station.

307. When the storage resource required by the user queue does not exceed the preset first threshold, the storage resource control energy saving module allocates a storage resource for the user queue from the basic storage resource.

When the storage resource required by the user queue does not exceed the preset first threshold, it indicates that the basic storage empty resource corresponding to the base station is sufficient for the user to use the queue. Therefore, the sharing is not required at this time. Storage resources apply for storage resources.

308. The service quality control module acquires a service curve of the network calculus, a user priority of the user in the cell, a buffer data accumulation status information, a service delay requirement information, and a service quality information.

309. The service quality control module adjusts a sending rate of the shaped service flow according to the service curve of the network calculus, the user priority of the user in the cell, the buffer data accumulation status information, and the service delay requirement information, so that the The rate of transmission of the shaped service flow satisfies the quality of service Information.

310. The QoS control module sends the adjusted service flow by using the adjusted transmission rate of the service flow, for example, to the base station or the user equipment.

It should be noted that, if the base station occupies the shared block (that is, the storage resource occupied by the user queue is allocated by the gateway from the basic storage resource and the shared storage resource), after the base station is used, the occupation needs to be occupied. The shared block (that is, the shared storage resource allocated to the user queue) is translated so that it can be subsequently provided to other base stations. Similarly, when the user moves out of the service area of the base station, the basic storage resources allocated to the user queue can also be translated for use by other users.

In addition, in order to further reduce unnecessary energy consumption of network resources, the shutdown control module may also shut down a storage resource corresponding to a base station whose traffic is less than a set value, and when receiving wake-up information about the base station, Wake up the storage resources corresponding to the base station, as follows:

51. The shutdown control module traverses the decision of each base station to perform sleep and resource shutdown.

52. The shutdown control module determines the current base station, and determines whether the current base station is in the sleep mode. If yes, step S3 is performed, and if no, step S4 is performed.

S3. If the base station is in the sleep mode, the shutdown control module wakes up the basic storage resource corresponding to the base station when determining the wake-up information of the base station, for example, the storage resource wake-up command can be released, and then step S5 is performed.

54. If the base station is not in the sleep mode, the shutdown control module sends a sleep instruction to the base station when determining that the base station reaches the sleep condition, the sleep instruction instructs the base station to enter the sleep mode, and shuts down the basic storage resource corresponding to the base station. Then, step S5 is performed.

The sleep condition is that the base station is in an idle state for a period of time.

55. The shutdown control module determines whether all base stations in the system are traversed, and if so, the process ends, and if not, returns to step S2.

As can be seen from the above, in this embodiment, a leaky bucket of different depths is set for different users to implement shaping of the service flow, and the shaped service flow is stored in the optimized storage space, so that the maximum service in the current technology can be avoided. The problem that the storage resources caused by the allocation of storage resources is wasted; moreover, because the scheme can also utilize the service curve of the network calculus, the user priority of the user in the cell, the buffer data accumulation status information, and the service delay requirement. The information is used to adjust the transmission rate of the shaped service flow, so that the transmission rate of the shaped service flow satisfies the service quality information, and therefore, the service can be guaranteed. Under the premise of quality information, further reduce energy consumption.

In addition, the solution can also coordinate the control of the transmission rate of the service flow, the cell sleep state, and the shutdown or activation of the corresponding storage space by interacting with the information between the base stations, so that the long-term occupation of resources by the base station with low traffic can be avoided. The waste of resources and wasted energy can further save resources and reduce energy consumption. Embodiment 4

In this embodiment, when performing resource allocation, the base station may consider information such as inter-base station interaction interference, resource usage, and energy consumption in addition to satisfying the user's service requirements, and target energy consumption optimization. The radio resources are dynamically allocated, and the resource allocation information is periodically reported to the gateway device.

As shown in FIG. 4a, the base station may include a resource block allocation module, a power allocation module, and a resource block resource symbol shutdown module, as follows:

(1) resource block allocation module;

The resource block allocation module determines the resource blocks occupied by the cell edge and the cell center according to the soft frequency multiplexing, and allocates the corresponding resource blocks to the users in the corresponding area according to the requirements of the service quality. At the same time, the resource block allocation information is also passed to the power allocation module.

(2) a power distribution module;

After the resource block allocation module performs resource block allocation for each user, it inevitably brings co-channel interference to the neighboring cell. At this time, the power allocation module may calculate interference from the neighboring cell on each resource block in each cell, calculate the total rate obtained by each user in the cell according to the interference and the allocated resource block, and perform an iterative algorithm on the total rate obtained by the user. The adjustment enables the total rate obtained by the user to minimize the power of the cell and reduce the interference to other cells while satisfying the minimum service rate, thereby achieving multi-cell interference coordination and achieving energy saving.

(3) resource block resource symbol shutdown module;

During the low traffic duration, each cell will have many free unallocated resource blocks. At this time, a symbolic shutdown operation can be performed on the unallocated resource blocks, for example, the symbolic shutdown technique can be used in those "no data transmission". Turn off the amplifier during the symbol period to further reduce power consumption.

Based on the structure of the foregoing base station, as shown in FIG. 4b, the specific process may be as follows:

401. The resource block allocation module sets the number of iterations to be 1; for each cell, initializes a resource block set that can be used in each cell to be A/" _m =Λ/", and performs equal power division on each resource block in the cell. Match.

402. The resource block allocation module receives the service flow from the gateway device, and allocates a resource block to each user in the cell according to each user service information requirement.

403. The power allocation module calculates interference from the neighboring cell on each resource block in each cell, and calculates a total rate obtained by each user in the cell according to the allocated resource block and the calculated interference.

404. The power distribution module determines whether the total rate obtained by the user meets the minimum service rate requirement of the user. If the minimum service rate requirement of the user is not met, step 405 is performed. If the minimum service rate requirement of the user is met, step 406 is performed.

405. The power allocation module increases the total rate obtained by the user, and returns to perform the step of determining whether the total rate obtained by the user meets the minimum service rate requirement of the user, that is, returns to step 404.

406. The power allocation module calculates a current cell power, and determines whether the current cell power is less than a preset cell maximum power. If yes, step 407 is performed. If not, the user that consumes the most power of the cell is rejected, and the rejected user is decreased. The total rate can then be performed in step 407.

407. The power allocation module updates the iteration number t, for example, adding t to 1, ie, =, +1, and then performing step 408.

408. The power allocation module determines whether the current number of iterations exceeds a maximum number of iterations t _max , that is, > t _max . If yes, step 410 is performed, and if no, step 409 is performed.

409. The power allocation module determines whether the allocation result of each cell has converged. If yes, step 410 is performed. If not, returning to the step of determining whether the total rate obtained by the user meets the minimum service rate requirement of the user, that is, returning to step 404.

410. The power distribution module sends resource allocation information to the gateway device, where the resource allocation information may include an allocation of resource blocks in the cell and an adjusted total rate obtained by the user.

For example, the resource allocation information may be specifically sent to the service shaping module and the quality of service control module in the gateway device.

In addition, in order to avoid waste of network resources and reduce power consumption, it is also possible to turn off the use of less resources, that is, step 411 can also be performed.

411, the base station determines whether the remaining unallocated resource block number exceeds a preset second threshold, and if the second threshold is exceeded, performing a symbol shutdown operation on the unallocated resource blocks; if the second is not exceeded The threshold ends the process.

The second threshold may be set according to requirements of an actual application.

As can be seen from the above, in this embodiment, resource blocks are allocated for each user in the cell according to the requirements of each user service information, and interference from neighboring cells on each resource block in each cell is calculated, and the resource block and interference are calculated according to the allocated resources. The total rate obtained by each user in the small area, and the iterative algorithm is used to adjust the total rate obtained by the user, so that the total rate obtained by the user satisfies the minimum service rate while minimizing the power of the cell and reducing interference to other cells. Finally, the resource allocation result is provided to the gateway device. Since the scheme calculates the total rate obtained by the user, not only the resource blocks to which the user is allocated but also the interference from the neighboring cells on each resource block are considered, and the total rate can also be utilized by using an iterative algorithm. The adaptive adjustment is performed so that the total rate obtained by the user can minimize the power of the cell and reduce the interference to other cells while satisfying the minimum service rate, so that not only the flexibility of resource scheduling but also the energy consumption can be reduced. waste. Embodiment 5

On the basis of the implementation of three and four, further, the solutions provided in the third and fourth embodiments can be implemented in combination, that is, the network energy-saving control is divided into two levels, and the first level is provided by the gateway device to different users.

The information exchanges coordinate control of the transmission rate of the service flow, the cell sleep state, and the shutdown or opening of the corresponding storage space to achieve the purpose of controlling the overall energy consumption of the network. The second level is based on the information of inter-base station interaction interference, resource usage and energy consumption, and the power consumption optimization is targeted to adaptively dynamically allocate radio resources, and periodically report resource allocation information to the gateway device.

Through such shaping, the burstiness of the service can be smoothed and the service smoothness can be ensured. The depth of the leaky bucket depends on the value of the shaping parameter, and the shaping parameter can be adjusted according to the service information and the load information of the base station, that is,

The shaping unit 503 is specifically configured to adjust the shaping parameter according to the network micro-integration principle according to the service information and the load information, and shape the transmission rate of the service flow according to the adjusted shaping parameter to obtain the shaped service flow.

The first threshold may be set according to the requirements of the actual application. The storage space of the gateway device can be divided into two parts, one part is the basic storage space allocated to the base station, and the other part is the shared storage space shared by the base station. The basic storage space is also called the basic storage resource, and the shared storage space is also called For details, refer to the previous embodiment, and details are not described herein again.

The processing unit 506 is configured to process the shaped service flow by using the allocated storage resource, for example, sending the shaped service flow to the base station device according to the user priority, and the like.

Optionally, in order to improve the quality of service, before the shaped service flow is processed by using the allocated storage resource, the sending rate of the shaped service flow may be adjusted, that is, the gateway device may further include an adjusting unit;

An adjustment unit, configured to obtain a service curve of network calculus, a user priority of a user in a cell, a buffer data accumulation status information, a service delay requirement information, and a service quality information, according to The service curve user of the network calculus adjusts the sending rate of the shaped service flow in the user priority of the cell, the buffer data accumulation status information, and the service delay requirement information, so that the sent rate of the shaped service flow satisfies the Service quality information.

In addition, if the base station occupies the shared block (that is, the storage resource occupied by the user queue is allocated by the gateway from the basic storage resource and the shared storage resource), after the base station is used, the occupied shared block is also needed. (that is, shared storage resources allocated to the user queue) are translated so that they can be subsequently provided to other base stations, namely:

The allocating unit 505 can also be configured to, after the processing unit 506 processes the shaped service flow by using the allocated storage resource, to release the shared storage resource allocated to the user queue.

Whether the base station enters the sleep mode and whether it is awakened or not can be controlled by the gateway, and may be determined by the base station itself. If the base station itself determines, the base station needs to notify the user to enter the sleep mode or wake up. a gateway, for the gateway to perform subsequent operations, for example, if the base station enters the sleep mode, the basic storage resource corresponding to the base station is turned off, and when determining the wake-up information of the base station, the basic storage resource corresponding to the base station is awake .

The service flow, and the load information reported by the base station is obtained by the obtaining unit 502, and then the shaping unit 503 performs the leak bucket shaping on the service flow (that is, the randomly arrived service flow) according to the service information and the load information carried in the service flow, and obtains the shape after the shaping. The service flow is established by the establishing unit 504 for the shaped service flow, and when the storage resource required to determine the user queue exceeds a preset first threshold, the allocation unit 505 is configured from the basic storage resource and the shared storage. The storage resource is allocated to the user queue in the resource, and the allocation unit 505 allocates the storage resource to the user queue from the basic storage resource, and finally the processing unit 506 processes the shaped service flow by using the allocated storage resource. In this solution, the service flow can be leak-buffered and the storage resources can be flexibly allocated according to actual requirements. Therefore, the storage resources caused by allocating the storage resources by the maximum amount of traffic in the current technology can be avoided. The problem, as well as avoiding the waste of unnecessary energy consumption caused by the storage space in the prior art is always saved, not only saves network resources, but also reduces energy consumption.

The processor can also be used to obtain a service curve of the network calculus, a user priority of the user in the cell, a buffer data accumulation status information, a service delay requirement information, and a service quality information; the service according to the network calculus The curve user adjusts the sending rate of the shaped service flow in the user priority of the cell, the buffer data accumulation status information, and the service delay requirement information, so that the sent rate of the shaped service flow satisfies the service quality information. In addition, if the base station occupies the shared block (that is, the storage resource occupied by the user queue is allocated by the gateway from the basic storage resource and the shared storage resource), after the base station is used, the occupied shared block is also needed. (that is, shared storage resources allocated to the user queue) are translated so that they can be subsequently provided to other base stations, namely:

The processor is also used to translate shared storage resources allocated to the user queue.

The processor is further configured to: when the user moves out of the service area of the base station, translate the basic storage resources allocated to the user queue.

Optionally, in order to further reduce unnecessary energy consumption of the network resource, the storage resource corresponding to the base station whose traffic is less than the set value may be shut down, and when the wakeup information about the base station is received, the device wakes up. The storage resource corresponding to the base station. which is:

The processor may be further configured to determine whether the base station is in a sleep mode; if yes, waking up the basic storage resource corresponding to the base station when determining that the wakeup information of the base station is received; And sending a sleep instruction to the base station, where the sleep instruction indicates that the base station enters a sleep mode, and turns off a basic storage resource corresponding to the base station.

For the specific implementation of the foregoing devices, refer to the foregoing embodiments, and details are not described herein again.

It can be seen that the gateway device in this embodiment receives the service flow between the core network and the base station, and obtains the load information reported by the base station, and then leaks the randomly arrived service flow according to the service information carrying the service information and the load information. After shaping, the service flow is obtained, and the user team 歹 ij is established for the shaped service flow. When it is determined that the storage resource required by the user queue exceeds a preset first threshold, the basic storage resource and the shared storage resource are The user queue allocates a storage resource. Otherwise, the storage resource is allocated to the user queue from the basic storage resource, and finally the shaped service flow is processed by using the allocated storage resource. In this solution, the service flow can be leak-buffered and the storage resources can be flexibly allocated according to actual requirements. Therefore, the storage resources caused by allocating the storage resources by the maximum amount of traffic in the current technology can be avoided. The problem, as well as avoiding the waste of unnecessary energy consumption caused by the storage space in the prior art is always saved, not only saves network resources, but also reduces energy consumption. Embodiment 10 Correspondingly, an embodiment of the present invention further provides a base station, including a processor, a transceiver device, and a memory for storing data, where:

a processor, configured to allocate, according to each user service information requirement, a resource block for each user in the cell, and calculate interference from the neighboring cell on each resource block in each cell; and calculate each cell in the cell according to the allocated resource block and the interference The total rate obtained by the user; the iterative algorithm is used to adjust the total rate obtained by the user, so that the total rate obtained by the user satisfies the minimum service rate, minimizes the power of the cell and reduces interference to other cells, and controls the transceiver device. Transmitting resource allocation information to the gateway device, where the resource allocation information includes an allocation of resource blocks in the cell and an adjusted total rate obtained by the user;

For example, the processor may be specifically configured to determine whether the total rate obtained by the user meets the minimum service rate requirement of the user; if the minimum service rate requirement of the user is met, calculate the current cell power, and determine that the current cell power is greater than or equal to the preset. When the maximum power of the cell is reached, the user that consumes the most power is rejected, and the total rate of the rejected user is reduced. When it is determined that the current cell power is less than the preset maximum power of the cell, the number of iterations is updated, and the current iteration number is determined to exceed the maximum. The number of iterations, or the step of transmitting the resource allocation information to the gateway device when the allocation result of each cell has been converged; and determining that the current number of iterations does not exceed the maximum number of iterations and the allocation result of each cell has not converged, returning to the execution judgment user obtains Whether the total rate meets the minimum service rate requirement of the user; if the minimum service rate requirement of the user is not met, the total rate obtained by the user is increased, and the execution returns to determine whether the total rate obtained by the user meets the minimum service rate requirement of the user. Sudden.

Before allocating resource blocks for each user in the cell according to the requirement of each user service information (ie, step 201), the resource blocks that can be used in each cell may be initialized first, and equal power allocation is performed on the resource blocks. which is:

The processor can also be used to initialize resource blocks that can be used in each cell, and perform equal power allocation on the resource blocks.

Optionally, the processor may further receive a service flow from the gateway device before allocating the resource block to each user in the cell.

Optionally, in order to avoid waste of network resources and reduce energy consumption, it is also possible to turn off the use of fewer resources, namely: The processor may be further configured to perform a symbol shutdown operation on the unallocated resource block when the number of unallocated resource blocks exceeds a preset second threshold.

It can be seen that the base station in this embodiment allocates resource blocks for each user in the cell according to the requirements of each user service information, and calculates interference from neighboring cells on each resource block in each cell, according to the allocated resource blocks and Interference calculates the total rate obtained by each user in the cell, and uses an iterative algorithm to adjust the total rate obtained by the user, so that the total rate obtained by the user meets the minimum service rate while minimizing the power of the cell and reducing the power to other cells. Interference, and finally the resource allocation result is provided to the gateway device. Since the scheme calculates the total rate obtained by the user, not only the resource blocks to which the user is allocated but also the interference from the neighboring cells on each resource block are considered, and the total rate can also be utilized by using an iterative algorithm. The adaptive adjustment is performed so that the total rate obtained by the user can minimize the power of the cell and reduce the interference to other cells while satisfying the minimum service rate, so that not only the flexibility of resource scheduling but also the energy consumption can be reduced. waste.
