Abstract

An interworking proxy is coupled to first and second mobile switching systems and translates between first and second management protocols used by the first and second systems, respectively. The first system requests service for a mobile user using the first management protocol. The proxy receives the service request and translates it from the first management protocol to the second management protocol, and then transmits the translated service request to the second system. The second system provides a response to the service request using the second management protocol. The interworking proxy receives the response and translates it from the second management protocol to the first management protocol, and then transmits the translated response to the first system.
