Embodiment Construction

[0040] The embodiment of the present invention adjusts the time slot priority determined based on SDCA power measurement according to the first interference power value of each time slot of each co-frequency adjacent cell to the own cell. Since strong interference is considered when adjusting the resource priority, the probability of strong interference in alternative target uplink resources is reduced, thereby reducing the number of handover failures and call drops caused by same-frequency and same-slot interference, and improving handover performance.

[0041] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, the method for adjusting resource priority in this embodiment of the present invention includes the following steps:

[0043] Step 101, determining the first interference power value of each co-frequency adjacent cell to each time slot of the cell;

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method and equipment for adjusting the priority of resources, aiming at solving the problems of handover failure and call drop caused by strong same-frequency and same time slot interference possibly in the switching process because strong interference easily exists in uplink resources of a standby target in the scheme of determining resource priority in the prior art. The method in the embodiment of the invention comprises the following steps of: determining a first interference power value of each same-frequency neighbor cell to each time slot of the cell; and adjusting the time slot priority determined by SDCA (Synchronization Data Communication adapter)-based power measurement according to the determined first interference power value. The strong interference is considered in the adjustment of the resource priority, so that the possibility that the strong interference exists in the uplink resources of the standby target is reduced, further the frequencies of handover failure and call drop due to same-frequency and same time slot interference are reduced and the handover performance is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for adjusting resource priority. Background technique [0002] At present, when a UE (User Equipment) performs a handover, it needs to select a resource with a high priority according to a resource priority list. [0003] In the wireless mobile communication system, the priority of resource allocation is given by a certain method or criterion, such as in TD-SCDMA (Time Division Synchronized Code Division Multiple Access, time division synchronous CDMA; CDMA, Code Division Multiple Access, code division In the multiple access) system, the SDCA (Slow Dynamic Channel Allocation) algorithm is used to give the resource priority order, and when switching, the resource selection is performed according to the resource priority order. [0004] In the current SDCA algorithm, the time slot priority can be sorted based on resource occupation, or...
