摘要： 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 link. The preferred system embodiment includes a gateway MSC, a serving MSC, and a base 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 gateway 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 an 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 gateway MSC, with all communication to and from the roaming mobile unit routed through the gateway MSC. The gateway MSC thereby maintains all call control for the roaming mobile unit for the implementation of advanced calling features, such as call 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 compatible messages are also utilized, a Gateway Origination Request containing the base station packet address and a Gateway Origination Request Return Result containing the new DLCI parameter.

摘要： A method for providing universal access to service features by subscribers of a wireless telecommunications service provider comprises establishing a gateway switch interconnected to a plurality of mobile switching centers maintained by other wireless service providers. Trunk connections and signaling links between each mobile switching center and the gateway switch allow the gateway switch to establish call connections and apply service features. Advantageously, the gateway switch is responsible for applying service features and establishing call connection for its subscribers and thereby, results in predictable access to wireless telecommunications services.

摘要： The present invention relates to wireless telephone networks, and more particularly to the allocation of radio channels to calls in CDMA-based systems when their Radio Access Networks (RAN) are congested. A Base Station (BS) receives a call origination from a mobile device. The BS communicates information about the call and about its radio availability to a Mobile Switching Center (MSC). The MSC determines the priority of the call and how the call should be treated by the BS based on the supplied information. The MSC communicates the treatment information and the priority information back to the BS.When the RAN is congested, high-priority calls are queued. These high-priority calls are served based on allocation specification in which radio channels may be assigned to low-priority calls, which are not queued, while there are still calls in the queue.

摘要： Techniques for providing enhanced wireless services such as interactive voice services to a serving mobile switching center which is originating a call for a mobile station that requires such services via the public switched telephone network (PSTN). The serving mobile switching center has a trigger which causes it to respond to a call from the mobile station by sending a message according to the IS 41 protocols to the enhanced mobile switching center that provides the enhanced service. The enhanced mobile switching center responds to the message by associating the contents of the message with a temporary local dialing number (TLDN) and sending a message to the serving mobile switching center that contains the TLDN. The serving mobile switching center uses the TLDN to set up a call via the PSTN to the enhanced mobile switching center, which then uses the content of the message associated with the TLDN to establish which enhanced service is required. It calls the service node for the enhanced service and bridges the call from the serving mobile switching center to the service node. The call provides a voice channel for the enhanced service.

摘要： A method and apparatus for completing a priority call to a wireless border switch. A priority or preemption request is transmitted as part of the signaling messages used to set up a call. A border switch is a switch which is used in conjunction with the switch indicated by the last-seen pointer from an HLR entry for the called terminal to page a called station. The switch indicated by the last-seen pointer transmits the priority request to a border switch, to indicate that the call should be given priority treatment. Further, preemption service for calls terminating on a wireless station can be provided. Advantageously, priority and preemption treatment can be provided for calls originated by wireless or landline stations and terminating on mobile station destinations that are served by a border switch; preemption or priority service can be provided for calls to a wireless station originated from a landline station; and preemption service can be provided for calls to a wireless station from a wireless station.
