Method of controlling a communication control entity

摘要

A method of controlling a communication control entity in a mobile communication network and a corresponding communication control entity are described. The communication control entity is a part of a pool of communication control entities. In accordance of the invention, when acting as a primary communication control entity and receiving a request for adding a new secondary communication control entity to the overall control procedure, the communication control entity of the invention is arranged to determine whether the requested new secondary communication control entity is a part of the pool or not. If it is a part of the pool, then the primary communication control entity established a direct connection to the access part. The requested communication control entity is not added to the control procedure as a relay.

1. A method of controlling a communication control entity in a communication control part of a mobile communication network that comprises a communication control part and an access part, said communication control entity acting as a primary communication control entity for a call communication and belonging to a pool of communication control entities among which no handover procedure is conducted as long as a mobile communication device moves among service realms associated with a predetermined number of access control entities that are connected to said pool, said method comprising the steps:
performing a handover to a first secondary communication control entity that does not belong to said pool, wherein the primary communication control entity acts as an anchor after the handover; receiving a handover request for removing the first secondary communication control entity from a control process for controlling said call communication and adding a second secondary communication control entity, determining whether said second secondary communication control entity belongs to said pool, and if said second secondary communication control entity belongs to said pool, not switching to said second secondary communication control entity to said control process and instead communicating directly by said primary communication control entity with the mobile communication device of which said given call communication is being controlled via an access control entity connected to said primary communication control entity without utilizing any secondary communication control entity.
