PROCESSING OF MOBILE ORIGINATED CALLS IN PACKET SWITCHED PROTOCOL BASED COMMUNICATION NETWORKS

摘要

The present invention relates to a method for processing a mobile originating telephone call in a packet switched protocol based communication network comprising a packet switched protocol based cellular telephone network (1) having a first layer (3) for transferring signalling information assigned to the telephone call being processed by the communication network, a second layer (4) for transferring payload information assigned to the telephone call, and interface means for coupling the cellular telephone network (1) to a further network (2), the method comprising: initiating a call by the mobile station (5), providing a base node address information identifying a base node of the second layer within the cellular telephone network (1), transferring the base node address via the first layer to the interface means under control of the first layer (3) in order to establish a through-connection within the second layer (4) for transferring payload information of the call from the interface means to the base node on the basis of the base node address information, providing interface means address information identifying the interface means within the cellular telephone network (1), and transferring the interface means address information via the first layer (3) to the base node under control of the first layer (3) in order to establish a both-way through-connection within the second layer (4) for transferring payload information of the call from the base node to the interface means and vice versa on the basis of the base node address information and the interface means address information.
