| 摘要 |
The present invention proposes a method for releasing at least a part of a connection in a two-layer communication network comprising a first communication network layer adapted to establish a communication channel to a terminal, and a second communication network layer adapted to establish an application layer connection, said method comprising the steps of: deciding in one of said first and second communication network layers that at least said part of said connection associated to said terminal is to be released, and forwarding said decision from said one of said communication network layers in which said decision has been taken, to said other of said communication network layers via an interface between said first and second communication network layers. Accordingly, each communication network layer has a knowledg e of the necessity to release a connection and is enabled to initiate suitable measures in order not to waste network capacities for a connection call whic h is or can no longer be active. The present invention also relates to a correspondingly operated communication network.
