A relay LTE-Advanced communication system 1 is described in which a base station 5-1 receives a request from an MME(mobile management entity) 9-1 that an overload procedure be started or stopped. The base station 5-1 inserts the identity of the MME into the request and forwards the modified request to a relay node 7. Alternatively, the MME inserts the identity into the request which is then forwarded by the base station. The relay node 7 then initiates or terminates the overload procedure, in accordance with the request, for mobile telephones which the MME that made the request serves 3-3 and 3-4, but not for mobile telephones which the MME does not serve3-5 . Whether a connection request during the overload procedure is accepted or rejected may depend upon the reason for the requested connection. The overload procedure is terminated by a request sent from the identified MM to the base station to the relay node. |
