Method and node of controlling the allocation of transmission resources to wireless terminals within a radio access network
First Claim
1. A method of controlling the allocation of transmission resources to wireless terminals within a radio access network, which resources are required for the provision of an IP Multimedia service to the terminals, the method comprising:
- in the event of a requirement to change the allocation of transmission resources to a given wireless terminal, sending the current location of the terminal within the radio access network from the terminal to an IP Multimedia Subsystem; and
sending a resource allocation request from a control node of the IP Multimedia Subsystem to a destination node within the radio access network identified using said location, the request causing a resource control node of the radio access network to change the allocation of access network resources to the wireless terminal.

14. An IP multimedia subsystem node arranged to facilitate the setting up and control of IP multimedia calls, the node comprising:
-
means for receiving the current location of a terminal within the radio access network from the terminal; and means for identifying a destination node within the radio access network using said location and for sending a resource allocation request from a control node of the IP Multimedia Subsystem to said destination node in the event of a requirement to change the allocation of transmission resources to a given wireless terminal, the request causing a resource control node of the radio access network to change the allocation of access network resources to the wireless terminal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
