    Abstract: PROBLEM TO BE SOLVED: To provide a universal access leading to a service function to a radio communication service subscriber even when radio communication service is served anywhere. SOLUTION: A gateway exchange is maintained by a radio communication service provider (local provider) not maintaining a radio interface system. When a mobile subscriber of a local provider makes a call, a mobile exchange center serving an area where the subscriber is resident at present is accessed. The mobile exchange center uses dial information to identify a mobile terminal equipment to subscribe to the service of the local provider and informs registration to the gateway exchange via a signal link. Then trunk connection is set up between the mobile exchange center and the gateway exchange. The mobile exchange center acts like a radio interface to allow the local provider to set up call connection and to provide the service function.

    Abstract: The apparatus, method and system embodiments of the present invention provide for maintaining call control at a gateway mobile switching center (MSC), for roaming mobile units, utilizing a packet network or link, such as an ATM lin k. The preferred system embodiment includes a gateway MSC, a serving MSC, and a bas e station having a wireless link with the roaming mobile unit. The gateway MSC includes a protocol handler for voice (PHV). For any given incoming call for the roaming mobile unit or outgoing call from the roaming mobile unit, the gatew ay MSC designates a specific address (or channel) on the PHV, referred to as a data link connection identifier (DLCI), for use as an address for voice packets to be received from the roaming mobile unit via the base station and serving MSC, and the base station also provides a base station packet address to the gateway MSC, for use as a n address for voice packets to be received from the gateway MSC (through the serving MSC) for the roaming mobile unit, thereby creating a full duplex packet link. The packet link serves as a voice path between the base station, the serving MSC, and gatewa y MSC, with all communication to and from the roaming mobile unit routed through th e gateway MSC. The gateway MSC thereby maintains all call control for the roaming mobile unit for the implementation of advanced calling features, such as cal l waiting and three-way calling. In the preferred embodiment, the DLCI is included as a new parameter for ANSI-41 compatible messages. In addition, new ANSI-41 compatib le messages are also utilized, a Gateway Origination Request containing the bas e station packet address and a Gateway Origination Request Return Result containing th e new DLCI parameter.
