A SYSTEM AND METHOD OF COMMUNICATING A PRIORITY INDICATION IN A CALL CONTROL/BEARER CONTROL TELECOMMUNICATION SYSTEM

摘要

The invention refers to a separated call control, bearer control telecommunications network. Communicating a call control level priority indication between two telecommunications nodes via the bearer network includes determining a call control level priority indication, assigning a bearer level priority indication to a priority indication field in a bearer network protocol message in accordance with a priority level of a bearer network protocol, and transmitting the bearer network protocol message via the bearer network from the first telecommunication node towards the second telecommunication node. In a further aspect, the invention refers to enabling transmission of a call control level priority indication along at least a portion of a path of communication established between a first telecommunication node and a second telecommunication node. This includes a particular mapping of a call control level priority indication to a bearer priority indication.
