Abstract:

A method of a mobile switching center includes determining if a message belongs to a first set of messages or a second set of messages, filtering the message when the message belongs to the first set of messages, and sending the message when the message belongs to the second set of messages. A method of an interworking solution includes receiving a message from an apparatus, determining if the message belongs to a first set of messages or a second set of messages, and discarding the message when the message belongs to the first set of messages. The first set of messages are 1x native messages unsupported for tunneling to a user equipment and the second set of messages are 1x native messages supported for tunneling to the user equipment for circuit switch fallback procedures.
