Abstract

The present invention relates generally to telecommunication services, and in particular, to communicating priority indications between telecommunication nodes in a telecommunication system having a separated call control and bearer control architecture. The present invention provides a number of solutions which map or assign the call level priority to the bearer level.

Claims

1-18. -18. (canceled)

19. In a separated call control, bearer control telecommunications network, a method of communicating a call control level priority indication between a first telecommunications node and a second telecommunications node via the bearer network including the steps of:

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;

transmitting the bearer network protocol message via the bearer network from the first telecommunication node towards the second telecommunication node.

20. In a telecommunication system having separated Call Control and Bearer Control architecture:

a method for 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, the path of communication including at least one bearer network node,

the method including;

mapping, in accordance with a dedicated relationship, a call control level priority indication to a bearer priority indication in a bearer network protocol message field in accordance with the following steps;

determining a Bearer Independent Call Control priority value;

determining a priority level in a bearer network for a message to be communicated in the bearer network based on the determination in step a).

21. In a telecommunication system, the system including a separated Call Control and Bearer Control architecture between a first telecommunication node and a second telecommunication node, an improvement including:

call control level priority determining means adapted to determine a call control level priority indication;

logic means adapted to logically map the call control level priority indication to a priority indication field in a bearer network message in accordance with a priority level of a bearer network protocol;

a transmitter adapted to transmit the bearer network protocol message within a bearer network via the bearer network from the first telecommunication node towards the second telecommunication node.

22. A bearer network protocol data unit for use in a telecommunications system having a separated Call Control and Bearer Control architecture, the bearer protocol data unit including:

a data payload field for communicating user data, and

at least one header field including a priority indication field serving to provide a priority designation of the bearer protocol data unit,

the priority indication field including an attribute based on a call control level priority indication for a call set up message.

23. In a separated call control, bearer control telecommunications network, a method of communicating a call control level priority indication between a first telecommunications node and a second telecommunications node via a bearer network including the steps of:

determining a bearer network priority level of a bearer network protocol message;

assigning a call control level priority indication to a call, the call control level priority indication being related to the bearer network priority level.

24. In a telecommunication system, the system including a separated Call Control and Bearer Control architecture between a first telecommunication node and a second telecommunication node, an improvement including:

priority determining means adapted to determine a bearer network priority level of a bearer network protocol message;

call control level priority assigning means adapted to assign a call control level priority indication to a call, the call control level priority indication being related to the bearer network priority level.
