LTE协议栈中PDCP层研究与设计
Research and design of PDCP layer in LTE protocol stack
摘要
Abstract
In LTE protocol stack PDCP( packet data convergence protocol) layer has many functions such as data encryption, integrity protection, header compression and so on. In order to achieve PDCP layer overall functions, this paper analyzed the PDCP function procedure and data unit structure, focused on the data transfer procedure for DRBs ( data radio bearer ) mapped on RLC ( radio link control ) A M ( acknowledgement mode), PDCP reestablishment procedure and status report in connection. A PDCP layer associated MSC( message sequence chart) was designed. The analysis shows that in the PDCP the new mechanism can guarantee the data in the sequential processing and prevent data loss and duplication.关键词
