Method for sonsultating working channel between adjacent base stations

Abstract

This invention relates to occupation and distribution of channels in the broadband radio access technology including: a newly initialized base station gets all channel information of IBS-NrI adjacent to it and selects channel S as the working channel, in which, all IBS-NrI occupying channel S at present own an escape channel at least, and IBS sends a request for switching channels to said IBS-NrI, which is switched to any of its escape channel T and IBS occupies channel S, in which, adjacent base stations can negotiate and adjust channels automatically so as to optimize resource distribution in the network.

Description

[technical field] [0001] The invention relates to channel occupancy and allocation in broadband wireless access technology, in particular to a method for negotiating working channels between adjacent base stations. [Background technique] [0002] Broadband wireless access technology is currently developing vigorously, and the technology of using wireless resources to carry out broadband metropolitan access has strong vitality and market space. At the same time, wireless channels become very valuable, especially in areas that are not well planned, or in license-exempt frequency bands (LE Band), often the same channel is operated by multiple base stations, resulting in mutual interference. In order to coordinate the work among devices on the same channel, especially the coexistence of devices in the license-free frequency band, and the coexistence of devices that have not undergone network frequency planning, it is necessary to establish some coexistence mechanisms between dev...

AI Technical Summary

Problems solved by technology

Its disadvantages are: ① It does not support dynamic configuration, and it is difficult to coordinate between operators; ② When the network changes, it cannot automatically adjust and negotiate, and must be re-planned, which results in low work efficiency

The disadvantage is that when a new base station joins the community, the channel distribution must be recalculated in the entire community

This will cause a considerable number of base stations in the community to switch channels

In particular, base stations that are far away from it also have the possibility of handover. In the mode of only wireless links, whether it is a centralized handover command or a distributed community topology update message, it needs to go through multi-level wireless links. The relay can only be transmitted to the corresponding base station in the community, the process is complicated, and it conflicts with the existing protocol, which is not conducive to the implementation, and also increases the cost of the terminal
