RRC research and implementation of LTE in handover procedure of TD-LTE to TD-SCDMA dual-mode terminals
LTE-TD双模终端切换过程的ERRC研究与实现

Based on the necessity of the TD-LTE/TD-SCDMA Dual-mode terminals research, the structure of TD-LTE and TD-SCDMA systems and LTE protocol are introduced. The finite state machine and interface of ERRC sub-layer, the handover procedure of TD-LTE to TD-SCDMA are designed through the research of the inter RAT principle in LTE system and ERRC in handover and measure procedure of TD-LTE to TD-SCDMA. The design and implementation of ERRC is verified through the SDL/TTCN test and verification platform, and it meets the 3GPP protocol specifications.
