根据3GPP协议,研究了GSM_TD-SCDMA重选判决、系统消息SI2quater发送机制,并在此基础上,对空闲态和数据业务态下的GSM至TD_SCDMA重选进行了实验,并结合理论研究,对GPRS至TD-SCDMA重选时延提出优化方案。
According to the 3GPP protocol, the GSM_TD-SCDMA reselection decision and the SI2quater mechanism of the system message are studied. And on this basis, the GSM to TD_SCDMA reselection in the idle state and the data service state are tested. Combining with the theoretical research, To TD-SCDMA re-election delay proposed optimization program.
