VORRICHTUNG UND DAZUGEHÖRIGES VERFAHREN ZUR UNTERSTÜTZUNG DER KOMMUNIKATIONSVERBINDUNG ZWISCHEN EINER MOBILSTATION UND EINEM KOMMUNIKATIONSNETZWERK

摘要

Apparatus, and an associated method, for forming a communication connection between a mobile station and a communication network. The communication network is of either of two protocol versions, such as a UMA-compliant network and a GAN-compliant network. A network access identifier is formed at the mobile station of a format that permits its acceptance by the communication network. If a first network access identifier is formed of a format that is incompatible with the protocol version of the communication network, a subsequent network access identifier is formed of the format of the other of the protocol versions. A listing is maintained at the mobile station that identifies the determined protocol version of the communication network.
