<p><P>PROBLEM TO BE SOLVED: To allow a call control gateway (GW) and a bearer gateway (GW) not to have a fixed 1:1 correspondence in a communication network with call control separated from bearer control. <P>SOLUTION: Information elements and methods to interpret transferred information are stored in receivers and senders related to the information, enabling the receivers and senders to transmit more pieces of information than originally planned at protocol design. Accordingly, a combination of a payload transmission device and a control node may be used in place of a single device. Additionally, an assignment may be regarded as a further assignment. This allows a change of a current assignment to a radio access controller. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
