[0036] Refer to the following figure 2 , to describe an embodiment according to one aspect of the present invention. Wherein, the wireless coexistence community includes several wireless communication networks, which may be based on different communication protocols and belong to different operators. In this embodiment, in a wireless coexistence community, a digital TV broadcasting network provides idle resources of the digital TV broadcasting network to a cellular mobile communication network, a wireless local area network, and a wireless metropolitan area network as an example for illustration. It can be understood that each network in the wireless coexistence community has a certain credit token value (Credit Tokens). The initial credit token value contained in each network is negotiated and determined by the operators of each network when the network is deployed. Credit tokens can be exchanged and circulated between various networks.

[0073] Refer to the following image 3 , to describe an embodiment according to another aspect of the present invention. The configuration and status of the wireless coexistence community and the wireless networks participating in the coexistence in this implementation are similar to those in the first embodiment above.

[0074] First, in step S10, broadcasting station A sends resource leasing information to network equipment that manages their respective network spectrum resources, such as base station B of the cellular mobile communication network, access node C of the wireless local area network, and base station D of the wireless metropolitan area network. Including the minimum credit token value MNCT for specifying the leased resource R.

[0075] Base station B, access node C and base station D receive this resource lease information. Then, judge whether it needs to rent the resource R, and judge whether the credit token held by itself is greater than the minimum credit...

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

technical field [0001] The invention relates to a wireless communication system, especially a wireless coexistence system composed of multiple wireless communication networks. Background technique [0002] With the wide deployment of various wireless communication systems based on different protocols, such as digital television broadcasting (DVB), mobile cellular communication, wireless local area network (WLAN) and wireless metropolitan area network (WiMAX), spectrum resources become increasingly scarce. In this case, the sharing of spectrum resources by various wireless networks becomes an effective way to utilize limited spectrum resources. [0003] In a spectrum sharing system, one of the most critical issues is how to dynamically allocate limited spectrum resources to multiple wireless systems. On the one hand, on the licensed frequency band, the spectrum sharing system generally can only opportunistically use the idle resources that have not been occupied by the lice...
