| Abstract: | In the LTE system, RRC Connection Re-establishment Procedure is very important in the aspects of maintaining the reliability of wireless link and ensuring continuity of service. The characteristics of LTE system and structure of protocol are introduced. The RRC connection re-establishment procedure is researched into the aspects of application scenario, launch cause, cell selection procedure and update of RRC connection configuration parameter. The finite state machine and interface of RRC\PDCP\RLC\MAC sub-layer, the flow of the RRC connection re-establishment procedure are designed. The design and implementation of RRC connection re-establishment procedure is verified through the SDL/TTCN test and verification platform, and it meets the 3GPP protocol specifications. |
