Abstract

In order to solve the problems of resource scrambling, fake leasing and so on, which possibly appear in the present wireless co-existence system based on credit, the invention provides a wireless co-existence method based on credit and the device thereof. On the one hand in the method, when the resource provider performs the resource auction based on requesting credit token, the current resource occupying quantity of the resource requesters is considered synthetically, and the scrambling to the rational resource requests of other resource requesters by the resource requesters that have already occupied much resource is reduced; on the other hand, the resource provider validates the received renting bids of resource requesters, and distributes resource to the resource requesters correctly validated. Thus, the fairness of resource sharing is increased and the communication performance of co-existence community is improved. Preferably, the invention combines the above two aspects, validates the renting bids of resource requesting devices, and among the resource requesting devices whose bids are correctly validated, selects a resource accepting device according to their resource occupying quantity, and performs resource sharing in a wireless co-existence community.

Description

Credit-based wireless coexistence method and device thereof

Technical field

The present invention relates to a wireless communication system, and more particularly to a wireless coexistence system comprising a plurality of wireless communication networks. Background technique

With a variety of wireless communication systems based on different protocols, such as digital television broadcasting

Various types of wireless networks, such as DVB, mobile cellular communications, wireless local area networks (WLANs), and wireless metropolitan area networks (WiMAXs), are widely deployed, and spectrum resources are becoming increasingly scarce. In this case, the sharing of spectrum resources by various wireless networks becomes an effective way to utilize limited spectrum resources. One of the most critical aspects of a frequency-sharing system is how to dynamically allocate limited frequency resources to multiple wireless systems. On the one hand, in the licensed frequency band, the spectrum sharing system can only opportunistically use the idle resources that have not been occupied by the authorized system for data transmission, and the state occupied by the primary system, that is, the busy state of these resources is random. In addition, the services currently carried in the frequency sharing system are mostly IP-based data services with dynamically changing traffic. In this case, if the traditional static wireless resource allocation method is adopted, it will result in:

1) The current channel utilization of some spectrum sharing systems is lower than the previously preset threshold, that is, the spectrum resources allocated to these spectrum sharing systems cannot be fully utilized; 2) other spectrum sharing systems currently require high spectrum resources. At the preset threshold, these systems cannot obtain enough spectrum resources to meet their current traffic load requirements. Want to solve the above Problem, it is necessary to design an effective dynamic allocation mechanism of spectrum resources to achieve coexistence of multiple wireless systems.

A wireless communication network can borrow or lease wireless communication resources that have not been actually used by it to other wireless communication networks with insufficient communication resources, so that spectrum resources can be fully utilized to improve spectrum utilization. Through the sharing or leasing of spectrum resources, a number of different wireless communication networks form a Co-exsitence Community, and they mutually coexist through the mutual lease of frequency resources.

In the wireless coexistence community, how to properly lease and use idle resources for each wireless communication network is an important issue that must be solved. In general, there is no central scheduler in the coexistence community to globally schedule the sharing of spectrum, so the distributed resource sharing scheme is an attractive solution. Currently, there are two ways to share resources: competitive and negotiated. In a competitive channel random access mode, such as the CSMA mode, multiple wireless systems dynamically share one or more idle channels (spectral resources) by transmitting respective data packets in the resource. However, data packets that are successfully transmitted by the respective wireless systems on the same radio resource may cause interference and conflict between the systems, resulting in a relatively low frequency usage. In contrast, in the negotiated resource sharing mode, a wireless communication network (resource provider) having idle spectrum resources can provide/lease spectrum resources in real time with each wireless communication network (resource requester) lacking spectrum resources. Negotiate. In this way, it is possible to ensure that the resource recipient has exclusive use of the idle spectrum resource within an agreed time, so that the spectrum resource has a higher spectrum utilization rate.

For resource negotiation, a dynamic resource provisioning/lease mechanism based on Credit Token (CT) is defined in IEEE 802.16h and IEEE 802.22, as shown in Figure 1. Show. First, a resource provider having an idle resource issues resource lease information to other resource requesters of the coexistence community, that is, base stations and broadcast stations of other wireless networks that manage spectrum resources of the network, and the information may include The information about the leased spectrum resources, such as the frequency band, the lease start time, and the end time, etc., may also specify a Minimum Number of Credit Token (MNCT) for renting the resource. After receiving the information, each resource requester determines whether it needs to rent the resource, and determines whether the credit token held by itself is greater than the minimum credit token value specified by the resource provider to rent the resource. If the determination is yes, the resource lease request message is sent to the resource provider. For example, the resource requester 1 and the resource requester 2 in FIG. 1 respectively send a resource lease request as a response to the resource lease information to the resource provider, where the request may include related information of the resource requester, and The bid for the resource (represented by the credit token value). When the resource provider receives the resource lease request sent by multiple resource requesters for a period of time, it selects the resource requester with the highest bid for the resource as the resource acceptor, for example, the resource requester 1 in FIG. . Then, the resource provider issues a lease reply to each of the two resource requesters 2 and 1, respectively, informing the resource requester 2 that it is not selected, informing the resource requester 1 that it is selected. Resource Requester 2 can exit the negotiation or request to lease other resources. The resource requester 1 may pay the agreed credit token value to the resource provider; after accepting the credit token value from the resource provider 1, the resource provider leases the resource to the resource requester 1; finally, the resource requester 1 Obtain and utilize the resources rented by the resource provider.

Although the resource provisioning/lease mechanism described above can guarantee exclusive use of leased resources, the mechanism has disadvantages that cannot be ignored in practical applications. On the one hand, some greedy resource requesters will seize a large amount of resources by paying a large amount of credit tokens in a short period of time, making other The resource requester's reasonable resource request is not met. This situation is similar to a resource robbing, affecting the fairness of resource sharing and the communication performance of the entire coexisting community. On the other hand, this mechanism lacks effective integrity supervision and punitive measures against dishonesty. Specifically, an untrustworthy resource requester may promise to give the resource provider more credit token value during the negotiation phase, and after the resource provider believes the resource requester's bid, it will reject the other offer lower but A resource requester who is honestly bidding, causes the resource provider's resources to be unavailable to resource requesters for these honest bids. Instead, the money of dishonesty

The fairness of source sharing is greatly reduced and affects the communication performance of the entire coexisting community.

The invention provides a reasonable negotiation mechanism for the provision/rental of wireless resources, avoids greedy preemption of resources, and provides an effective integrity supervision and punishment measures for dishonesty, and improves the fairness of resource allocation and multi-system coexistence. Performance is very necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail from the viewpoint of a method with reference to FIGS. 2 to 4. First Embodiment Hereinafter, an embodiment according to an aspect of the present invention will be described with reference to FIG. The wireless coexistence community includes a plurality of wireless communication networks, which may be based on different communication protocols and belong to different operators. In this embodiment, a digital television broadcasting network, a digital television broadcasting network, provides a cellular mobile communication network, a wireless local area network, and a wireless metropolitan area network to provide idle resources of the digital television broadcasting network as an example for description. It can be understood that each network in the wireless coexistence community has a certain credit token value (Credit Tokens). The initial credit token values contained in each network are negotiated by the operators of each network when the network is deployed. Credit tokens can exchange streams between networks Pass. First, in step S10, the resource providing device, that is, the management device device broadcasting station A of the digital television broadcasting network, requests the device in the same coexistence community, that is, the base station B of the cellular mobile communication network, and the access of the wireless local area network. The node C and the base station D of the wireless metropolitan area network send resource lease information, which includes information about the leased resource R, such as the frequency band of the R, the lease start time, and the end time, etc., and the information may also include the broadcast. The minimum credit token value MNCT leased by the station A for the resource R.

The base station B, the access node C, and the base station D receiving device receive this resource lease information. Then, it is judged whether it needs to rent the resource R, and it is judged whether or not the credit token held from the broadcaster is larger than the minimum credit token value MNCT of the lease designated by the broadcast station A. Specifically, the base station B and the access node C judge that they need the resource R, and each of the credit tokens held by the base station B and the access node C are greater than the requirements of the broadcast station A, and the base station B and the access node C become resource requesters, and each of them has a resource. The lease request (referred to as resource request) is sent to the broadcast station A as a response to the resource lease information, where the request includes related information of the base station B and the access node C, respectively, and the bid for the resource (denominated by the credit token value) N _{CT B} and N _CT — (. While base station D does not need this resource, it does not respond.

In step S11, the broadcast station A receives the base station within a predetermined reception response time.

A resource lease request of B and access node C containing lease leases each denominated in credit tokens. Next, the broadcast station A acquires the current resource occupation information S _fl ^ of the base station B and the access node C, that is, the cellular mobile communication network and the wireless local area network. , — _c . Preferably, each wireless network in the coexistence community maintains the number of spectrum resources such as the frequency band of the radio resources currently occupied by each network. The resource occupation information may be information of a spectrum leased by a network, or may be a total amount of spectrum that it is using, including its spectrum and its leased spectrum. and many more. It can be understood that the broadcast station A can also obtain the resource occupation information of each wireless network that performs the resource request through a third-party resource database that maintains the resource occupation information of all the networks in the wireless coexistence community. In another case, the base station B and the access node C respectively add the current resource occupation information of the base station B and the access node C in their resource lease requests.

Then, in step S13, the broadcast station A selects the resource accepting device based on the lease price and resource occupancy information of the base station B and the access node C.

Specifically, in step S130, the broadcast station A determines the credit bid discount value of the base station B and the access node C based on the number of occupied spectrums of the base station B and the access node C. This embodiment uses a discount function Λ _∞ί Γυ _ί . Make a decision:

ί 1 1

Among them, _3⁄4 . _ω is a threshold for judging whether the network has excessively occupied the wireless spectrum: when the number of frequency words U殳 occupied by the network exceeds, the requested credit token discount value is the same as the requested credit token value; when the frequency number exceeds The request credit token discount value will be proportionally smaller than the requested credit token value, so that the resource requester who has occupied more spectrum resources must pay more credit token value to compete with other resource requesters for spectrum resources. The resource robbing of these resource requesters is reduced. The S _threshhold may be the same for each wireless network, which is relatively fair; the threshold may also be different in other considerations, for example, according to the traffic volume of the network itself. It can be understood that the above discount function is not unique, and those skilled in the art can The method of depositing the community network environment, the traffic volume of each wireless network, and its credit, and determining a reasonable method for determining the credit value of the credit token, the specification is not described here. For the base station B and the access node C, the broadcast station A calculates the request credit discount value H _{t B} , s , , respectively. For example, in the embodiment, the base station Β and the access node C respectively use 50 credits. The value of the currency and the value of the 40 credit token are requested. After the discount function is calculated, the requested credit token discount values of the base station 接入 and the access node C are 25 and 30, respectively. Then, in step S131, the broadcast station 请求 requests the size of the credit token discount value according to the base station B and the access node C, and selects the access node C that requests the largest credit token discount value as the resource accepting device. The broadcast station A issues a lease reply to the base station B and the access node C to inform the lease result.

Next, access node C pays its promised 40 credit token value. In step S15, the broadcast station A accepts the 40 credit token value of the access node C.

30 requesting a credit token discount value, allocating spectrum resources to the access node C, and updating resource occupancy information of the access node C maintained by the broadcast station A.

In step S16, the broadcast station A transmits the leased related information such as the provided spectrum resource amount and the related information of the access node C to the other network base station B and the base station D of the wireless coexistence community to update the access node C. Resource usage information. In another case, the broadcast station A may also send the lease-related information to the aforementioned third-party resource database as another resource requesting device to update the resource occupation information of the access node C.

In addition, since the request credit token discount value of the access node C is less than the request credit token value, the lease related information of the broadcast station A further includes credit compensation related information, which is used to assist the network base station B and the base station D to their respective credit generations. The currency value is compensated. The credit compensation related The information includes the mean of the difference between the 40 request credit token value and the 30 request credit token discount value, ie

N——2

Where ^ is the number of wireless networks in the wireless coexistence community. In this embodiment, the calculation result is 5. In step S17, the base station B and the base station D receive the rental related information of the resource R from the broadcast station A selected by the broadcast station A and provided to the access node C; and, due to the requesting credit of the access node C The currency discount value is less than the requested credit token value, and the rental related information also includes credit compensation related information.

In step S18, the base station B and the base station D respectively update the resource occupation information of the access node C in the number of spectrum resources currently occupied by each network, and the base station B and the base station D will access the node C. The resource occupancy increases the corresponding spectrum resource R. In order to provide spectrum resources in the future, consider the real-time spectrum occupancy of access node C.

In step S19, the base station B and the base station D compensate for their own credit token values based on the credit compensation related information. Specifically, base station B and base station D can directly accept the mean value of the difference between the 40 request credit token value of the access node C and the 30 request credit token discount value. It can be understood that the base station B and the base station D can also calculate based on the request credit token value received by the access node C to the broadcasting station A and the request credit token value received by the broadcast station A, which is received in step S16. The mean value of the difference between the credit token value and the requested credit token discount value is 5, and the calculated compensation value 5 is accepted as an increment of its credit token value.

In this embodiment, in the case that the request credit token discount value is less than the requested credit token value, the resource acceptor spends the request credit token value to rent the required resource, and the resource provider obtains the request credit token discount value, which The difference between the two values is the same within the coexistence community As shared by his resource requesters, this principle of distribution has certain fairness. It can be understood that the present invention is not limited thereto, and in another case, the resource provider can also enjoy the difference and not distribute it to other resource requesting devices.

It can be understood that, in the current resource leasing process, the broadcasting station A is a resource providing device, and in contrast, the access nodes and base stations of other wireless networks are resource requesting devices; in other resource leasing processes, other wireless networks are The management device, for example, the access node C can provide its spectrum resources for lease, in contrast, the devices such as the broadcast station A, the base station B and the base station D become resource requesting devices.

The present embodiment has been described above from the viewpoint of a method. Similarly, this aspect of the invention can also be implemented on a device product, which will be briefly described below from the perspective of the device.

The resource providing apparatus according to the present embodiment, for example, the broadcasting station A, includes a device 1 for resource sharing, wherein the device includes a transmitting device 10, a processing device 11, a selecting device 12, a distributing device 13, and a providing device 14. The resource requesting device, e.g., base station B, access node C, and base station D, includes a device 2 for resource management, wherein the device includes a first receiving device 20 and an updating device 21.

First, the transmitting device 10 broadcasts resource lease information for renting the spectrum resource R to each of the base stations 2 and C and the base station D.

The lease information receiving means of the base station B and the access node C receives this resource rent information.

Then, the base station B and the access node C determine that the spectrum resource R needs to be leased, and it sends a resource lease request to the broadcast station A, the resource lease request respectively containing lease prices N _{CT B} and N _CT — (for example, credit tokens). :.

Next, the processing device 11 receives the resource lease request from the base station B and the access node C containing the lease price. The processing device also determines resource occupancy information for base station B and access node C. , _—β and . , — _c . Preferably, each wireless network in the coexistence community maintains the number of frequency resource resources such as frequency bands of radio resources currently occupied by each network.

Subsequently, the selecting means 12 selects the resource accepting device from the base station B and the access node C's rental bid and its resource occupancy information.

Specifically, the selecting device 12 includes a determining device 120 for base station B based And resource occupancy information ^ and access node C. , — _c , using the default discount function f—(m _eshhold ), determining the credit bid discount value fdisc t( N _Ct , ^ actual _B, ^ threshhold _B ) of each resource requesting device and f discounti ^ ct _C, ^ Actual _C, ^ threshhold _C ) ° "^ Hai's reference to the description of the above method embodiment.

Then, the selecting means 12 selects, according to the credit bid discount value of the base station B and the access node C, the access node C having the largest credit bid discount value as the resource accepting device.

Next, the distribution device 13 accepts the credit bid discount value provided by the access node C, allocates the resource to the access node C, and updates the resource occupancy information of the access node C.

Thereafter, the providing means 14 supplies the rental related information to the base station B and the base station D of the wireless coexistence system. When the credit bid discount value of the access node C is less than the requested credit token value, the lease related information further includes credit compensation related information.

The first receiving means 20 of the base station B and the base station D receives the rental related information from the broadcasting station A for performing the selection processing of the resource accepting device.

Then, the updating means 21 updates the resource occupation information of the broadcasting station A and the access node C based on the rental related information. Specifically, the update device 21 increases the resource usage of the access node C by the corresponding frequency resource R.

When the rental related information further includes credit compensation related information, the device 2 further includes a compensation device 22 for increasing the credit of the resource requesting device based on the credit compensation related information. Second embodiment

An embodiment in accordance with another aspect of the present invention will now be described with reference to FIG. The configuration and state of the wireless coexistence community and the wireless networks participating in the coexistence in the present embodiment are similar to those in the above first embodiment.

First, in step S10, the broadcast station A issues resource lease information to the network device that manages the respective network spectrum resources, such as the base station B of the cellular mobile communication network, the access node C of the wireless local area network, and the base station D of the wireless metropolitan area network. A minimum credit token value MNCT specifying the leased resource R is included.

Base station B, access node C, and base station D receive this resource lease information. then, It is judged whether it is necessary to rent the resource R, and it is judged whether or not the credit token held from the broadcaster is larger than the minimum credit token value MNCT of the leased resource designated by the broadcast station A. Specifically, the base station B, the access node C, and the base station D both determine that the resource is required, and the base credits held by the base station B and the access node C are at the MNCT required by the broadcast station A, but the credit generation held by the base station D The coin is smaller than the MNCT required by Broadcast Station A. In this embodiment, the base station D is an untrustworthy resource requester, which lie that it has more credit token values and wishes to destroy this time resource sharing. In this case, the base station B, the access node C, and the base station D become resource requesters, and respectively send a resource lease request (referred to as resource request) as a response to the resource lease information to the broadcast station A, where the request is includes a base station-related information, respectively, C ^ access node and the base station D, and the bid for the resource (credit request token value), N _CT _C and N _{CT D.} Where β is the untrustworthy bid of base station D, and base station D does not actually have so many credit token values.

In step S110, the broadcast station Α receives the resource rental request of the base station B, the access node C, and the base station D, which respectively contain the lease price information and the resource occupation information, which are denominated by the credit token, within the predetermined receiving response time. . Next, in step S111, the broadcast station A judges the base station 2 to access the lease price of the node C and the base station D, that is, whether the credit token is requested to be authentic. Specifically, in step S1110, the broadcast station A acquires the reference credit token values of the base station B, the access node C, and the base station D. Preferably, each wireless network in the coexistence community maintains a credit token value currently held by each network, and the broadcast station A uses the credit token value currently held by the base station B, the access node C, and the base station D maintained by the station A as a base station. B. Reference credit token values of access node C and base station D. It can be understood that the broadcast station A can also obtain the credit token value of each wireless network that requests the resource through a third-party credit database that maintains the credit token value of all the networks in the wireless coexistence community. Next, in step S1111, the broadcast station A compares the base station ^ the access node C and the base The reference credit token value of station D and the request credit token value included in the resource request from base station B, access node C and base station D received by broadcast station A: if the resource requester's request credit token value is not greater than its holding The credit token value is true, otherwise the bid is not true. By comparison, the broadcast station A finds that the request credit tokens of the base station B and the access node C are authentic; the request credit token of the base station D is not authentic.

Then, in step S1112, for the base station D requesting the credit token information to be untrue, the broadcast station A deducts the penalty credit token value N _Dish ty from the locally maintained credit token value currently held by the base station D. The penalty value N _Dishonesty a predetermined penalty value

The smaller of the two values of the credit token value currently held by base station D. Scheduled penalty value

It may be agreed in advance by each wireless network in the coexistence community, which may be the same for each wireless network, or may be different for each wireless network based on the creditworthiness of each wireless network.

Moreover, the penalty credit token value deducted by the base station D is compensated to all other resource requesters in the wireless coexistence community. Specifically, the corresponding compensation value of the broadcast station A to the credit token value of the broadcast station A is in the wireless coexistence community.

The number of wireless networks.

Further, in step S1113, the broadcast station A transmits the penalty related information and the related information of the base station D to the base station B, the access node C, and the base station D of the wireless coexistence system. The information indicates that the base station D has made an untrustworthy bid in the current resource sharing; and indicates that the base station B and the access node C should deduct the penalty credit token value from the credit token currently held by the base station D maintained by the base station, and Add the corresponding compensation value for your credit token; Base station D deducts its own penalty credit. In another case, broadcast station A can also punish related information. Sending to the aforementioned third-party credit database as another resource requesting device, deducting the penalty credit token value from the credit token currently held by the base station D it maintains and the credit generation from the base station B and the access node C The corresponding increase in the currency increases the corresponding compensation value.

Next, in step S1114, the base station B, the access node C, and the base station D receive the penalty related information from the broadcast station A, and the related information of the penalized base station D.

Then, in step S1115, the base station B and the access node C deduct the penalty credit token amount Λ^ ₅ from the credit of the base station D that is _maintained . And adding a corresponding compensation value 7 to the credit token of the resource requesting device. In step S1116, the base station D deducts itself to punish the credit token N _Dlslwnesty and retreats the negotiation.
