Patent ID: 8059557

Claim:
A method performed by a radio access network (RAN), wherein the RAN comprises a base transceiver station (BTS), wherein the RAN selects an access gateway to serve a wireless communication device (WCD), and wherein the RAN maintains a profile associated with the WCD containing a representation of network usage history of the WCD, the method comprising: for each access gateway of a plurality of access gateways, measuring a respective round trip latency between the RAN and the access gateway; performing a comparison of the measured respective round trip latencies, wherein performing the comparison comprises rank ordering, from lowest to highest latency, the plurality of access gateways based on their measured respective round trip latencies; receiving, at the BTS, an incoming call indication from the WCD associated with an incoming call from the WCD; based at least on the comparison of the measured respective round trip latencies and the representation of network usage history of the WCD, selecting as the access gateway one of the plurality of access gateways that has a measured respective round trip latency greater than or equal to a median measured respective round trip latency of the plurality of access gateways; and assigning the incoming call from the WCD to the selected access gateway.
