CONNECTION RELEASE IN COMMUNICATION NETWORK

摘要

A communication management mechanism for a communication network, such as a cellular multi-type communication network, is proposed in which the core network determines whether a user equipment, which was connected hitherto to the core network via an access network subsystem, is still reachable via a signaling connection to this specific access network subsystem when a connection release procedure is to be performed. When it is determined that the access network subsystem is assumed by the core network to have no means to reach via a hitherto signaling connection the user equipment anymore, a specific indication element is generated which indicates the result of the core network that the user equipment can not be reached by the access network subsystem via this hitherto signaling connection. This indication element is transmitted to the access network, for example, in connection with a connection release command. The access network recognizes this indication element and determines that there are no means to reach the user equipment via the hitherto signaling connection. Due to this, normally performed unsuccessful signaling trials to the user equipment may be prevented.
