Abstract:

    After the investigation of the existing Baton Handover (BH) algorithms in cellular networks, a new BH algorithm in the Time Division Synchronous Code Division Multiple Access (TDSCDMA) system is developed, which is called resource reservation based preferential queuing scheme with selfadaptive threshold. Simulation results show that this algorithm improves the PRI of VIP and high rate users. When the call rate of handover is higher, the division of users can improve the QoS of the system and the efficiency of the total channel utilization. The BH lost rate by the new method is reduced by 50% compared with the PRI method. The advantage of this new method is more obvious as the user move rate is high.

Key words: communication, TD SCDMA, radio resource management (RRM), baton handover (BH), priority(PRI)
