Abstract:
A method of tunneling a message capsule, containing one or more non-GSM signaling messages, from a mobile station of a non-GSM network that uses a GSM serving GPRS support node and a gateway GPRS support node to provide packet service to a one mobile switching center of a plurality of mobile switching centers that operate using non-GSM protocols, comprising the steps of:constructing a tunneling of messages protocol envelope, at the mobile station, including the message capsule and information specific to the non-GSM protocols; transmitting the tunneling of messages protocol envelope to the serving GPRS support node; determining, at the serving GPRS support node, that the one mobile switching center is to receive the message capsule based on a routing area identifier corresponding to the mobile station and the information specific to the non-GSM protocols; and transmitting the message capsule to the one mobile switching center.
