Title:
COMMUNICATION SYSTEM, RELAY TERMINAL, REMOTE TERMINAL, AND COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/051503
Kind Code:
A1
Abstract:
Remote UE (300) transmits a first signaling for user registration of the remote UE (300) with an MCPTT server (100). The MCPTT server (100) detects a connection relationship between the remote UE (300) having transmitted the first signaling and relay UE (200) to which the remote UE (300) connects. Upon reception of voice data from UE to which the right to speak is given, the MCPTT server (100) determines, as destination UE to which the voice data is to be transmitted, only one UE from among the relay UE (200) and remote UE (300) having the connection relationship, and transmits the voice data by use of a unicast bearer for the destination UE. The relay UE (200) transmits the voice data, transmitted from the MCPTT server (100), to all of the remote UE (300) connected to the relay UE (200).
