Packet data services using a protocol that is different than a subscriber's home network GSM Protocol

Abstract

A wireless voice and data communication system facilitates providing packet data services to mobile subscribers even when they roam into areas that are served by a system that operates using a protocol different than the subscriber's home system protocol. In one example, a subscriber profile including appropriate authorization for packet data services that conforms to a GSM/GPRS protocol is mapped from a home location register (HLR) that uses the GSM protocol to a visitor location register that uses a CDMA/ANSI-41 protocol so that the GSM mobile subscriber obtains packet data services through provider system that uses the CDMA/ANSI-41 protocol.
