METHOD IN A MOBILE STATION FOR MAINTAINING PLMN CONTINUITY WHEN MOVING BETWEEN NETWORKS OF DIFFERENT TYPES AS A FUNCTION OF PLMN CONTINUITY PREFERENCE

摘要

Mobile station methods and systems for maintaining PMLN continuity when moving between networks of different types as a function of PLMN continuity preference are provided. PLMN continuity preference concerns a preference for the mobile station when transferring from a first network type, such as cellular, to a second network type, such as GAN to reduce the possibility of dropping calls, for example. The mobile station transmits this preference to the network, and the mobile station then perform network selection based on the preference.
