Abstract:
An evolved packet core less direct-mode communication system and a communication attaching method thereof are provided. The evolved packet core less direct-mode communication system comprises a client direct-mode communication apparatus and a server direct-mode communication apparatus. The server direct-mode communication apparatus transmits a synchronization signal to the client direct-mode communication apparatus. The client direct-mode communication apparatus synchronizes to the server direct-mode communication apparatus according to the synchronization signal and establishes a communication connection with the evolved packet core less direct-mode communication system after synchronization.
