Abstract
A 2G controlling entity in a common 2G/3G network that includes a common Core Network is connected to dual mode mobile stations and to a 3G controlling entity also connected to dual mode mobile stations. The 2G controlling entity applies a 3G camping strategy and receives a service request, for a service at least supported by the 2G network, from a dual mode mobile station. The 2G controlling entity instructs the dual mode mobile station, when connected to the 2G network, to perform cell reselection evaluation of 3G network cells only when the 2G network signal strength is below a predetermined threshold.
