COMMUNICATION SYSTEM

摘要

A communication system is disclosed in which a relay communication device identifies a service to be received by at least one other communication device and also identifies the at least one communication device. The relay communication device maintains a mapping between services and the communication device(s) that need to receive that service. The relaying communication device receives service data using a broadcast/multicast bearer and forwards, using a respective device-to-device bearer, the service data to each communication device for which a respective mapping to that particular service is maintained.
