Claim:
A method of managing a communication connection of a user equipment in a communication network, the method comprises the steps of: processing received signaling information related to the user equipment in order to determine whether or not the user equipment is still reachable via at least one first signaling connection for an access network subsystem through which the user equipment was connected hitherto; and sending, if the user equipment is not reachable, a specific indication element to the access network subsystem, wherein the specific indication element indicates that the user equipment is not reachable for the access network subsystem via the at least one first signaling connection, and wherein the determination is based on detecting that signaling related to the user equipment is forwarded via at least one of the following: a different access network, a different interface and a different signaling connection, wherein the specific indication element is included in a connection release message to release at least one second signaling connection of the user equipment to a core network subsystem, and wherein the specific indication element is a specific cause code in a signaling message.
