Abstract:
1. In a communication system comprising pooled circuit switched core network nodes and packet switched (PS) core network nodes, a method of transferring a mobile station (MS), the method comprising the steps of: moving the MS from a first pooled CS core network node to a second pooled CS core network node; sending a first message from the first pooled CS core network node to the second pooled CS core network node to establish if the second pooled core network node will accept the MS; and sending a second message from the first pooled CS core network node to a first PS core network node upon the second pooled core network node accepting the MS, the second message including the address of the second pooled CS core network node and information regarding a location update to the second pooled CS core network node, whereupon the first PS core network node sends a location update to the second pooled CS core network node according to the information in the second message.
