1. A relay node for a communication system comprising a plurality of mobility management entities (MMEs), the relay node comprising:
- a controller for associating a plurality of mobile devices with the relay node wherein each mobile device is served by an MME of said plurality of MMEs; and
a receiver for receiving, from a donor base station, a request that an overload action be performed and identity information representing an identity of an MME that requested the overload action,wherein the controller is arranged to selectively perform said requested overload action in respect of the mobile devices associated with the relay node in dependence on the identity information representing an identity of an MME that requested the overload action.

Abstract
A relay communications system is described in which a base station receives a request from an MME that an overload procedure be started or stopped. The base station inserts the identity of the MME into the request and forwards the modified request to a relay node. The relay node then initiates or terminates the overload procedure in accordance with the request for mobile telephones which the MME that made the request serves, but not for mobile telephones which the MME does not serve.
