| Abstract: |
| According to the 3GPP protocol,this paper analyses the message data and
control information in the interaction of the RRC (Radio Resource Control) conn
ection setup message transmission process, which is proposed by LTE system in re
cent years. The interfaces primitives between layers and parameters description
are defined,and a communication optimization scheme between the layers is propos
e
d in order to simplify the amount of interfaces primitives in the current system
design and the corresponding design of message sequence chart. The scheme can e
ffectively simplify the system implementation complexity and improve resource ut
ilization. |
