APPARATUSES AND METHODS FOR REDUCING A LOAD ON A SERVING GATEWAY IN A COMMUNICATIONS NETWORK SYSTEM

摘要

The exemplary embodiments of the present invention relate to a proxy entity for reducing a load on a serving gateway. This is achieved by the proxy entity comprising a cross connecting circuit configured to receive from a MME, a cross connect set up request message to establish a tunnel between the proxy entity and the serving radio base station. The circuit is configured to establish the tunnel towards the serving radio base station. A receiver of the proxy entity is configured to receive, from the MME, a request to handover the UE from the serving to a target radio base station. The cross connecting circuit is further configured to establish a cross connect tunnel towards the target radio base station using an identifier of the established tunnel and an address of the target radio base station. The exemplary embodiments of the invention also relate to a MME.
