Abstract
A communication system (1) is disclosed in which a relaying user device (UE-R) (3-2) obtains bit rate information (e.g. aggregate maximum bit rate, AMBR) for relaying data for another (relayed) user device (UE) (3-1, 3-3). The obtention of said bit rate information may by receiving a message from the another (relayed) device, UE1, for registering the UE1 to an application server, AS (PSCC). The registration message may comprise UE1 identity, UE-R identity and information identifying a bit rate required by the UE1 while communicating via the UE-R (e.g. an AMBR parameter such as Relay-APN-AMBR). The UE-R sends the registration message received from the UE1 to a core network (7) node (e.g. a gateway device like a P-GW or S-GW, an MME, or a PCRF) comprising the information identifying a bit rate for relaying communication data for the UE (3-1, 3-3) to which the bit rate information relates. The UE-R (3-2) relays data received from the UE (3-1, 3-3) to a base station (5), and relays data for the UE (3-1, 3-3), received from the base station (5), to the UE (3-1, 3-3).
