GROUP COMMUNICATION BY RELAY

摘要

Group communication within a mobile telecommunications network having a plurality of User Equipment (UE) can be achieved. At a first UE, there is received an identification of a multicast group from which a second UE of the plurality of mobile terminals is to receive data. If the first UE is not a member of the multicast group, a request is sent from the first UE to join the multicast group. The first UE is identified at an application server associated with the multicast group. Data packets associated with the multicast group are subsequently communicated from the application server to the first UE and these are broadcast from the first UE to be received by the second UE.
