Research On Connection Establish Process In LTE-A

With the commercialization of LTE,LTE enters high-speed development period.LTE-Advanced is the evolutionary and features enhanced version of LTE.It can achieve higher riser data rates,greater system capacity,wider coverage and lower costs.Connection establishment is the essential part in LTE-Advanced network.It can confirm the communication between network and users reliable.The connection establishment process is mainly completed by the RRC layer and MAC layer coordination.It is mainly used for the initial registration of users,uplink synchronization and resource requirements.In this paper,a connection establishment protocol processing platform in eNB and UE in LTE-A is realized.It can achieve the functions of establishment of communication links.In addition,solution schemes are proposed based on the analysis of the failure of connection establishment.Connection establishment protocol processing platform has been tested by functional and performance test in various access causes to verify the function of connection establishment processing platform.
