Aiming at the state of the current LTE system network side MAC layer is uncertain
the network MAC layer state division scheme is presented in the process of LTE system communication.In this scheme
the network side MAC layer is divided into four states
the state transfer process and random access process designed thus achieved MAC state transition scheme.TTCN and SDL co simulation test proves state transition and random access process design is feasible
providing an effective program for the LTE system communication.
