摘要

针对TD-SCDMA系统现有快速动态信道分配算法的不足

提出了一种基于优先级信道预留的快速动态信道分配算法。该算法根据接力切换用户的移动台属性设定不同的优先级

为接力切换呼叫预留信道

结合小分组借用算法

增加了可移动边界动态信道分配(MBDCA)策略的灵活性。仿真结果表明

此算法相对于混合数据速率、小分组借用(MRG

mixed-data rate grouping borrowed)MB DCA算法

实现了VIP和快速移动切换用户的优先接入

有效地降低了切换呼叫的阻塞率

提高了数据业务性能和系统的信道利用率。

Abstract

Aiming at overcoming the shortages of the current fast dynamic channel allocation algorithm in TD-SCDMA system

a novel fast dynamic channel allocation algorithm based on priority channel reservation was proposed.This algorithm defined call priority by equipment attribution of baton handover user

reserved channels for baton handover calls.Combining with grouping borrowed algorithm

the algorithm made MB DCA strategy more flexible.Simulation results show that

comparing to the mixed-data rate grouping borrowed algorithm

the proposed algorithm achieves the preferential access of VIP and high rate mobile user

reduces the call failure probability resulted from the baton handover

improves the performance of data service

and increases the channel utilization efficiency.
