Description

Measurement control method, user terminal, network side device, and wireless communication system

The present invention relates to the field of communications technologies, and in particular, to a measurement control method, a user terminal and a network side device for implementing the method, and a corresponding wireless communication system. Background technique

It is well known that in the actual operation of a network of a wireless communication system such as the Universal Mobile Telecommunications System (UMTS), an overload situation may occur. In the case of overload, in order to guarantee the quality of service of existing connected users, the network usually restricts new users from accessing the network, or relocates new users to different frequency layers or radio access technologies than the current serving cell (RAT, Radio Access). Technology). The relocation of the user is mainly implemented by using an RRC connection setup message or an RRC connection reject message in the RRC (Radio Resource Control) connection establishment process, or by RRC connection during the RRC connection release process. Establish a release message implementation. In the current technical solution, the user terminal (UE) carries the measurement result of the frequency layer used and unused by the UE in the RRC connection request message sent to the network side. Therefore, when the network side needs to perform a relocation indication for the UE, the network side may indicate that the UE relocates to a suitable frequency layer according to the measurement result reported by the UE. In addition to being able to instruct the UE to relocate to a different frequency layer, the network side may also instruct the UE to relocate to a different RAT. However, the current relocation indication for the RAT is a blind indication in the UMTS system. That is to say, the current UE does not measure the RAT, and there is no RAT-related measurement result that can be sent to the network side. Therefore, when the network side performs the relocation indication of the RAT, there is no support for any RAT measurement data. To solve the problem of RAT blind indication in relocation, the UE may be set to send an RRC connection. The IRAT (Inter Radio Access Technology) handover measurement is performed before the request message, and the measurement result is reported to the network side in the RRC connection request message. In the process of implementing the present invention, the inventors have found that at least the following technical problems exist in the prior art: Although the processing can solve the problem of RAT blind indication in relocation, it also brings the following two problems.

1. This process affects the call setup performance of the UE. This is because the UE needs to perform IRAT measurement every time from the initiation of the call setup request to the transmission of the RRC connection request message to the base station, which inevitably prolongs the call setup delay.

2. The UE usually performs unnecessary measurements and reports. The UE does not know whether the network side will relocate the UE after the call is initiated. Therefore, the UE needs to perform a measurement before each time the RRC connection request message is sent, and report the measurement result. On the other hand, the network side does not need to relocate the UE frequently, so it is unnecessary for the UE to have multiple measurements and reports. In addition, in the Long Term Evolution (LTE) system, the requirements for automatic network setup and optimization are proposed. In order to support automatic network optimization, the UE needs to perform some additional measurements to provide measurement data to the network side, so that the network side can perform data accumulation for network setting and optimization. Moreover, in order to know the measurement data of the network in a complex environment, the measurement and reporting triggered by the UE based on certain information is also required. In summary, the UE needs to measure more information in the wireless communication system. However, there is currently no measurement control scheme that can reduce the impact of the measurement on the performance of the UE while ensuring that the UE provides the measurement result to the network side in time. . Summary of the invention

The main technical problem to be solved by the embodiments of the present invention is to provide a measurement control method, so that the UE provides measurement results for the network side while minimizing the impact of the measurement on the UE performance.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. As shown in FIG. 1A, the processing flow of the method embodiment of the present invention corresponds to the following steps: Step 101: The UE receives measurement indication information provided by the network side. The measurement indication information provided by the network side is used to indicate whether the UE needs to perform measurement processing, and the network side may send the measurement indication information to the UE by using broadcast and downlink signaling. The indication information may specifically be the indication information related to the load on the network side, the indication information related to the service, and of course other information, and may include multiple indication information at the same time. Step 102: The UE determines, according to the received measurement indication information, that the UE needs to perform measurement, and performs measurement processing. The measurement process can be specifically set as needed. For example, any one or any combination of the same frequency measurement, the inter-frequency measurement, and the different system measurement may be included.

In the above process, the UE only receives the measurement indication information of the network side, and after determining that the UE needs to be measured according to the measurement indication information, performs measurement, so that the UE can perform measurement according to the requirements of the network side, thereby ensuring the UE. It does not make frequent measurements, and ensures that the UE can perform targeted measurements, and minimizes the impact of measurements on UE performance. In addition, after step 102, as shown in FIG. 1B, step 103 may be further added, that is, the UE sends the measurement result to the network side. The UE may inform the network of the measurement result by means of signaling entrainment, or directly notify the network by using dedicated signaling, or may use L1/L2 control signaling, or a MAC header to inform the network, and of course, may also use other transmission methods. As long as you can guarantee the measurement results to the network.

As described above, in step 101, the measurement indication information received by the UE may be multiple, and the following corresponds to the load-related indication information and the service-related indication information in the specific embodiment 1 and the specific embodiment 2, respectively. The specific processing is described in detail.

In the first embodiment, if the network side provides the indication information related to the load, the UE determines, according to the received measurement indication information, that the UE needs to be measured, in step 102, according to the indication information related to the load, whether the network side is currently determined. Overload, if overloaded, it is determined that the UE needs to measure. Specifically, the load-related indication information provided by the network side may be a load status indication, or may be an overload indication directly. Wherein, if it is a load condition indication, it may be an actual load value or an indication of a load level. It may also be corresponding indication information of the load value or the load level. For example, the identifier corresponding to the load value or the load level may be set. When the load related indication information is provided, the load value and the load level may not be directly provided, but may be provided. The corresponding indication information of the information, that is, the identifier corresponding to the information. If the load-related indication information is directly the overload indication, the processing in the foregoing step 102 is: the UE directly determines, according to the overload indication, that the current load is an overload, and determines that the UE needs to perform measurement.

If the load related indication information is the load status indication, the processing of the foregoing step 102 is: the UE determines the load value of the current load or the load level according to the load condition indication, and the load value or the load level and the load threshold value. For comparison, if it is greater than the load threshold, this condition can be referred to as overload, and it is determined that the UE needs to perform measurement. The load threshold may be set by the UE or may be set by the network side. If set by the network side, the network side needs to notify the UE of the load threshold by broadcasting, signaling, or other means.

For the first embodiment, the network side informs the UE of the load-related indication information, and the UE determines whether it needs to be measured according to the indication information related to the load, so that the network side can obtain the measurement result of the UE when needed, and ensure The UE does not perform frequent measurements, and ensures that the UE can perform targeted measurements, and minimizes the impact of measurements on UE performance. When the RAT relocation is performed on the UE when the load exceeds the preset threshold, the network may perform RAT relocation according to the received measurement result; the network side may also perform network setting and optimization according to the received measurement result; The environment is analyzed based on the measurements received.

In the second embodiment, if the network side provides the service-related indication information, the UE determines, according to the received measurement indication information, that the UE needs to be measured, in step 102, specifically: determining the network side service according to the service-related indication information. Whether the related information and the service information of the UE are in a preset relationship, and if yes, it is determined that the UE needs to be measured. The service-related indication information provided by the network may be related information of the service supported by the network, for example, the identification information of the service, and may be the indication information of the service information. For example, the indication information may be It is a priority indication, a level indication, and the like. Of course, the above two indications can also be included at the same time. If the service-related indication information is the service indication information, the process of the foregoing step 102 is: the UE determines the service supported by the network side according to the service indication information, and determines whether the service of the local UE is consistent with the service supported by the network side. If they are inconsistent, it is determined that the preset relationship described above is met, that is, the UE determines that the measurement needs to be performed when the two are inconsistent. If the service-related indication information is the indication information of the priority indication, the level indication, or the like, the processing of the foregoing step 102 is: the UE determines, according to the indication indication information, between the service of the UE and the service supported by the network side. Relationship, and determining whether the relationship conforms to a preset relationship according to a preset policy. Specifically, when the priority level and/or the level indication of the service of the UE is higher than the service supported by the network side, the relationship is determined to be consistent with the preset. The relationship, which determines the need to perform the measurement that needs to be performed.

If the service-related indication information includes the service indication information and the differentiation indication information, the processing of the foregoing step 102 is: first determining whether the service of the local UE is consistent with the service provided by the network side, and if not, directly determining that the measurement needs to be performed; otherwise, Further, the relationship between the service of the UE and the service supported by the network side is further determined, and the measurement is performed when the priority level and/or the level indication of the service of the UE is higher than the service supported by the network side according to the preset policy. Or perform measurements when the services are supported below the network side. Of course, it can also be set to other processing methods as needed. Since the various processings are basically the same in principle, they are no longer described. For the second embodiment, the network side informs the UE of the service-related indication information, and the UE determines whether it needs to be measured according to the indication information related to the service, so that the network side can obtain the measurement result of the UE when needed, and ensures that The UE does not perform frequent measurements, and ensures that the UE can perform targeted measurements, and minimizes the impact of measurements on UE performance. When the network side needs to perform RAT relocation on the UE, the RAT relocation can be performed according to the received measurement result; the network side can also perform network setting and optimization according to the received measurement result, and can also be received according to the received environment in a complex environment. The measurement results were analyzed. In addition, as described above, the indication information provided by the network side may also include the load-related indication information and the service-related indication information. In this case, different processing policies may be set as needed. For example, in a step 102, after receiving the indication information, the UE first determines the specific situation of the current load according to the received load-related indication information. If it is determined that the current load is an overload, the UE directly determines the need. Performing the measurement; otherwise, determining the relationship between the service provided by the network side and the service of the UE according to the received service-related indication information, and determining whether the measurement needs to be performed according to the preset policy. The specific judgment process for the service-related indication information is as described in the foregoing Embodiment 2, and therefore is not described herein again. The processing considers the load situation on the network side and the service-related indication information, thereby further ensuring that the UE performs the measurement processing only when needed, further reducing the measurement frequency of the UE, and further ensuring the measurement of the UE. And further reduce the impact of measurement on UE performance.

In addition, to further reduce the measurement frequency of the UE, a measurement period can also be set. In the above step 102, after determining that the UE needs to be measured, the UE may perform measurement after the measurement period arrives. The measurement period is set according to requirements, for example, may be set according to service differentiation. For example, for real-time services, the measurement period may be set shorter, and for non-real-time services, it may be set longer; It can be set according to the load situation. For example, when the network load is better, the measurement period can be set longer, and in the case of a larger load, the real-time availability of the measurement result can be set shorter. It can also be set based on the information of the UE, such as the power of the UE, the discontinuous reception (DRX, Discontinuous Reception), the moving speed, and the QoS (Quality of Service). For example, when the UE's power is sufficient, you can do more measurements, so you can set the measurement period to be shorter. When the battery is low, you should minimize the measurement. The measurement period can be set longer. The measurement cycle can also take into account the DRX cycle. If the DRX cycle is long, the measurement cycle is set longer, otherwise it is set shorter. Due to the high speed mobile UE location The change will be faster, so if the UE moves faster, the measurement period needs to be set shorter, otherwise the measurement period can be set longer. When the measurement period is set according to QoS, in order to adjust the service with high QoS requirements in real time, the measurement period needs to be shorter. Otherwise, the measurement period can be set longer. The above only explains the corresponding relationship between the measurement period and the influencing factors. In different application scenarios, the measurement period can be reset according to the different setting relationship between the above-mentioned influencing factors and the measurement period.

It may also be that the setting UE does not directly perform the measurement after determining that the measurement is needed, but waits until the UE initiates the uplink connection before performing the measurement. Correspondingly, in step 103, the UE may send the measurement result to the network side through the uplink connection signaling related to the uplink connection, and may also retrieve other transmission modes.

The above two processes further reduce the measurement frequency of the UE, further ensure the measurement of the UE, and further reduce the impact of the measurement on the performance of the UE.

In addition, in order to reduce the reporting frequency of the UE, the reporting criterion of the UE may also be set, so that in step 103, before transmitting the measurement result to the network side, the UE first determines whether the reporting criterion is currently met, and only after the reporting criterion is currently met. , the sending process is executed. The reporting criterion may be a set reporting threshold, or may be a reporting period, and the reporting criterion may be determined by the network side and sent to the UE. In the foregoing processing scheme, if all the UEs are required to perform measurement on the network side, the indication information may be directly notified to the UE by broadcasting. If the network side only needs to perform measurement on the UE with certain characteristics, it only needs to inform the part of the UE of the indication information, and if the network side sends the indication information by broadcast, it needs to inform which UE needs to perform measurement according to the information. Or to inform which UEs do not need to measure, the processing is usually implemented by adding the identification information of the UE in the broadcast message. If the network side is notified by signaling, it is necessary to separately send signaling for these UEs. In an actual network, there is usually a case where there are multiple similar UEs in a network. For example, some UEs may have the same user subscription information such as user level and payment method, and some of them have approximately the same moving speed. Some are the same QoS requirements for the service and so on. In the embodiment of the present invention, the UE group may further be configured, and the group may be specifically determined according to the following conditions and any combination thereof: user subscription information including but not limited to user level and payment method. , wireless signal quality, hierarchical cell, mobile speed, and QoS of services. After the UE group is set, the network side only needs to add the corresponding UE to the broadcast message or the downlink signaling when the measurement indication information of the UE group with the certain characteristics is sent to the UE in the UE group. Information about the UE group such as the grou identifier and the UE grou attribute. Of course, the network side may send broadcast messages or downlink signaling to UEs in multiple UE groups at the same time. In this case, only relevant information of these UE grous needs to be added in the broadcast message or the downlink signaling. Correspondingly, the UE may determine, according to the received UE grou related information, whether the message or signaling is a message or signaling that the UE needs to receive, that is, the UE determines whether the UE belongs to the UE group that needs to perform measurement, and if yes, Receiving the message or signaling, and performing corresponding processing, that is, determining whether the UE needs to perform measurement according to the measurement indication information; otherwise, the message or signaling may be directly discarded. Certainly, the UE may further determine whether the measurement is needed according to the measurement indication information, and then the UE determines whether the UE belongs to the UE group that needs to perform measurement, and if yes, the UE performs measurement. After the UE grou is set, the network side can set the corresponding measurement indication information according to the characteristics of the UE grou. For example, if the user level is relatively high, or is the user of the prepaid service, the network side should generally ensure that it accesses, and does not handle its mobility. Therefore, the indication information may not be set for this type of UE group, or an indication may be set. The information is: No measurement is required by the UE. In addition, the UE group may also have user subscription information, wireless signal quality, hierarchical cells, The feature value of any one or any combination of the moving speed and the QoS of the service. In this case, when the network side sends the measurement indication information to each UE grou, the network side can also simultaneously send related information of the feature values set by the network side for the corresponding UE group, and can be broadcast, paging, and RRC. The information about the feature value is sent by means of signaling, L1/L2 control information, and MAC header. The UE in each UE grou can compare the feature value related information in the measurement indication information with the feature value of the local UE grou, and determine, according to the preset policy, whether the UE needs to further determine, according to the measurement indication information, whether the UE needs to be Perform measurement processing. Or the UE first determines whether it needs to be measured according to the measurement indication information, and after determining that the measurement is needed, whether the characteristic value of the indication and the characteristic value of the UE group satisfy the setting relationship according to the preset policy, and if yes, the UE performs measuring. The preset policy may be set as needed. For example, when the feature value sent by the UE on the network side and the feature value of the UE grou satisfy certain conditions, regardless of what information is provided by the measurement indication information, The UE does not need to perform measurement; or if the eigenvalue sent by the network side and the eigenvalue of the UE grou meet certain conditions, the network side needs the user terminal to perform measurement, according to the policy, if the UE is based on the If the policy is determined, the UE may further determine whether the UE needs to perform measurement according to the information provided by the measurement indication information. If the UE determines that the UE needs to perform measurement according to the measurement indication information, the UE determines that the UE needs to be measured according to the policy. , then the measurement process can be performed. The certain condition is set according to the requirement. For example, the feature value sent by the network side may be greater than the feature value of the UE grou, or the feature value sent by the network side may be smaller than the feature value of the UE grou.

It can be seen from the above description that after the UE group is set, the network side can formulate corresponding measurement and/or reporting mechanisms for different UE groups without setting each UE separately, which is convenient. Measurement control of the UE by the network side. For each UE in the UE group, after receiving the indication information for the UE group, it may determine, according to the indication information, whether the UE should perform measurement. In addition, after the UE group is set, the network side may set corresponding indication information according to the characteristics of the UE group, if the user level ratio If the user is higher, or is a user of the prepaid service, the network side should normally ensure that it accesses and does not handle the mobility. Therefore, the indication information may not be set for this type of UE group, or the indication information is: The UE performs measurements. Embodiments of the method of the present invention also provide Embodiment 3 and Embodiment 4, and the two solutions are described in detail below.

Embodiment 3 Since the UE usually has a preferred cell, the preferred cell may be in a different RAT, or a different version of the same RAT, preferably a certain RAT or a certain version/capable cell, and of course other situations. In the case that there is a preferred cell, if the cell side provides the cell list information, the UE determines, according to the received measurement indication information, that the UE needs to be measured, in step 102, specifically: the UE determines the received cell list information. Whether the preferred cell of the UE is included, if included, it is determined that the UE needs to be measured. The cell list information is specifically: information about a cell adjacent to the cell. In the third embodiment, the UE can also perform periodic measurement as needed. The processing of the specific periodic measurement is as described above and will not be described here. For the third embodiment, the network side sends the cell list information to the UE, and the UE performs measurement for the preferred cell, so that the UE can reselect the preferred cell as soon as possible, better obtain the service provided by the network, and reach the network. The role of load balancing. And the UE does not need to perform measurement processing frequently.

The fourth embodiment may also exist for the UE: The UE has a corresponding preferred area, but the UE is not currently in the preferred area. The preferred area may specifically be a TA (Tracking Area), RA (Routing Area i or Routing Area), or LA (Local Area i or Local Area). Of course, it may be other situations. For example, it may be an area composed of an LS A (Localized Service Area) or some special cells, and may specifically be an area composed of a private network cell. In the case of the foregoing scenario, if the network side provides information about the area to which the cell in which the user terminal is located, the UE determines, according to the received measurement indication information, that the UE needs to be measured in step 102. The related information of the area to which the current UE is located determines whether the area belongs to the preferred area of the UE. If not, the UE needs to perform measurement processing; if yes, the measurement process does not need to be performed.

The information about the area to which the cell in which the user terminal is located is located may be the ID information of the area, and the information may be sent by using a broadcast message, or may be other information. The transmission method is also various, as long as the UE can be received.

The measurement process performed by the UE may be to initiate measurement for all adjacent areas, that is, for cells in the adjacent area, or to initiate measurement only for the frequency layer where the preferred area is located.

In addition, in order to further reduce the measurement amount of the UE, the UE may also read the broadcast message of the neighboring cell, and determine whether the area to which the cell belongs depends on the information about the area to which the cell belongs in the received broadcast message. a preferred area belonging to the UE, if not, the UE does not use the cell as a measurement target cell, that is, does not perform measurement processing on the neighbor cell; if yes, the neighbor cell needs to be measured, and After the measurement determines that the neighboring cell can satisfy the reselection condition of the UE, it reselects to the cell. After the UE reselects the cell to which the preferred region is located, the measurement of the other cell may not be performed until the current cell cannot meet the camping condition of the UE, and the reselection is required. The insufficiency of the UE's camping condition may be determined according to the measurement S criterion in the idle state. The above process of reading the broadcast message of the neighboring cell and performing the determination may be performed after the UE determines that the measurement needs to be performed, or may be performed at any time before the measurement. For the fourth embodiment, the network side sends the information about the area to which the cell in which the user terminal belongs is sent to the UE. When the area does not belong to the preferred area, that is, when the current cell does not belong to the preferred area, the UE performs the information. The measurement enables the UE to reselect to the preferred area as soon as possible, better obtain the services provided by the network, and achieve the role of network load balancing. And the UE does not need to perform measurement processing frequently. In addition, the third embodiment and the fourth embodiment may be combined. For example, the UE may preferentially perform the determining process in the fourth embodiment, that is, whether the area to which the current cell of the UE belongs belongs to the preferred area, and if yes, the UE does not need to Performing any measurement processing; after determining that the area does not belong to the preferred area, the determination processing may not be performed immediately, but the determination processing in the third embodiment is performed first, that is, whether the neighboring cell has a cell located in the preferred area, And the measurement process is performed only in the case where there is a cell located in the preferred area. Thereby the measurement frequency of the UE is further reduced. Similarly, the above four embodiments may also be used in combination, and the specific use cases may be derived from the above four embodiments, and thus will not be described in detail herein.

Those of ordinary skill in the art will appreciate that all or part of the steps in implementing the above-described embodiments may be performed by program-related hardware. The software corresponding to the embodiment can be stored in a computer readable storage medium. As shown in FIG. 2, the UE of the embodiment of the present invention includes: a receiving module, a determining module, and a measuring module, where the receiving module is configured to receive measurement indication information provided by the network side, and send the measurement indication information to the determining module. The measurement indication information may be the indication information related to the load on the network side, the indication information related to the service, and of course other information, and may include multiple indication information at the same time. The determining module is configured to determine, according to the received measurement indication information, whether the UE needs to perform measurement, and send notification information that notifies the measurement module to perform measurement processing after determining that the measurement is needed. A measurement module, configured to perform measurement processing according to the received notification. And the measurement process performed by the measurement module may be one or any combination of the same frequency measurement, the inter-frequency measurement, and the different system measurement. The processing required to be performed by the foregoing determining module is specifically as described in the foregoing step 102, the first embodiment, the second embodiment, and the subsequent description in FIG. For example, for the determining module, if the received measurement indication information is the network-side load-related indication information, the determining module needs to determine whether the network side is currently overloaded according to the load-related indication information, and if yes, Make sure you need to measure.

If the indication information related to the load on the network side is specifically the load status indication, the determining module determines whether the network side is currently overloaded according to the indication information related to the load, and specifically: determining the load of the current load according to the load status indication. The value or load level, the resulting load value or load level is compared to the load threshold, and the network side overload is determined when the load value or load level is greater than the load threshold.

If the received network-related load-related indication information is specifically an overload indication, the determining module may directly determine, according to the overload indication, that the network side is currently overloaded.

If the measurement indication information received by the determining module is the service-related indication information, the determining module needs to determine, according to the service-related indication information, whether the service-related information on the network side and the service information of the user terminal meet the preset Relationship, if yes, then determine that the UE needs to measure.

The determining module determines whether the service-related information on the network side and the service information of the user terminal meet the preset relationship, if the information about the service-related indication is the information of the service supported by the network. To: Determine whether the service on the network side is consistent with the service of the user terminal. If they are inconsistent, determine that the relationship is consistent with the preset. If the received service-related indication information is specifically distinguishing indication information, the determination module Determining whether the relationship between the service-related information on the network side and the service information of the UE is in a preset relationship is as follows: determining, according to the indication information, the relationship between the service supported by the network side and the service of the UE, and according to the preset measurement The policy determines if the relationship conforms to a preset relationship. As described above, the preset measurement policy may be: determining that the preset relationship needs to be performed when the priority level and/or the level indication of the service of the UE is higher than the service supported by the network side, thereby determining that the need for execution is required. Perform measurements.

If the received service-related indication information includes the service indication information and the differentiation indication information, the determining module determines whether the relationship between the service on the network side and the service in the UE is in a preset relationship. Whether the services provided by the network side are consistent. If they are inconsistent, they are directly determined to be measured. Otherwise, the relationship between the service of the UE and the services supported by the network side is further determined, and the service of the UE is performed according to a preset policy. The measurement is performed when the priority level and/or the level indication is higher than the service supported by the network side, or when the service is supported below the network side. Of course, it can also be set to other processing methods as needed. Since the various processes are basically the same in principle, they are no longer described. As described above, the UEs in the network may be grouped according to the characteristics of the UE, and the network side may carry the provided measurement indication information in the broadcast message when the UE in the UE group that needs to have the specific characteristics is determined to perform measurement.
