A communication management mechanism for a communication network, in which the core network determines whether a user equipment, which was connected 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 not be able to reach via a signaling connection the user equipment, an 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.
