Setting a communication channel
First Claim
1. A method of setting up a communication channel for transferring call related control messages in a packet switched wireless communications network, the method comprising the steps of:
- sending, from a first network element to a second network element, a request to setup a communication channel, said request having an indication indicating that the communication channel will be used for transferring call related control messages to or from said first network element.

Abstract
In a packet switched wireless communications network, a parameter of a communication channel request indicates that the communication channel is to be used to transfer call related control messages. Upon receipt of the communication channel request, a network element sends a request to a radio access network that a part of the communication channel should be setup to transfer call related control messages. Another network element sets filtering information to allow only specific messages to be transferred on the communication channel. Specifically, the filtering information is set such that only call related control messages may be transferred on the communication channel. The other network element then sends the filtering information to the user equipment (UE). The UE derives the uplink filtering information from the received filtering information.

25. A method for use in a wireless communications network in which data packets are transferred through the network on a communication channel, said method comprising the steps of:
-
sending a request message to setup said communication channel from a mobile terminal to the network, and including, in said request message, a parameter which indicates whether or not said communication channel request will be used to transfer call related control messages. - View Dependent Claims (26, 27, 28)
