Abstract:
1. A method of processing calls in a wireless telecommunications network, the method comprising: receiving a call from a calling party to a called party at a Mobile Switching Center (MSC); determining whether a Media Gateway (MGW) is necessary at the MSC to begin to process the call; setting up a call bearer path between the calling party and the called party via a Radio Network Controller (RNC) controlled by the MSC and via an MGW at the MSC only if necessary to process the call, wherein the framing on a path between the RNC and the MGW is selected to be the same as the framing on a path from the MGW towards the remainder of the network; after the call has been set up, receiving a call event at the MSC while the call is in process, wherein the call event triggers a change in the current state of the call; determining whether an MGW at the MSC is necessary to process the call event; and inserting or removing an MGW at the MSC during the call depending on the requirements of the call event.
