摘要:
A communication system (100) employs a method of messaging between a subscriber unit (105) and an infrastructure communication center (101). A messaging key associated with a subscriber unit reference number is provided (203, 403) to the subscriber unit (105) and to the infrastructure communication center (101). An authentication key and/or an identifier for the subscriber unit (105) is then produced (300, 407) by either the subscriber unit (105) or the infrastructure communication center (101). The authentication key and/or the identifier is encrypted (207, 413) with the messaging key and is subsequently communicated (209, 415) between the subscriber unit (105) and the infrastructure communication center (101).

A communications system for providing packet data service to mobile stations (110) performs registration of the mobile station prior to engaging in packet data service. The registration procedure includes sending a request to register (300) to a DAP (113), transferring (302) subscriber data from a HLR (124) to a D-VLR (126), authenticating (306) the mobile subscriber, selecting a mobile data gateway (116) to service the mobile station, transferring (308) the subscriber data from the D-VLR to the mobile data gateway, and establishing (312) a packet data link between the mobile data gateway and the mobile station.
摘要:
An apparatus and associated method employ the concept of a central busy list for coordinating the receipt of incoming calls to a subscriber subscribing to the calling services of separate first and second communication networks. The central busy list apparatus cooperates with the networks to register a current call by a subscriber serviced by the first network, to receive a request for interruption of the call serviced by the first network to allow the subscriber to receive an incoming call to be serviced by the second network, to send a request to disconnect to the first network when a priority of the current call is lower than the priority of the incoming call, and to deny interruption of the current call by the incoming call when the priority of the current call is higher.
摘要:
Circular call forwarding loops are prevented for a communications unit (12) capable of operating in a first communications network (14) and a second communications network (16) within a loosely coupled network (16), and respectively having a first network number and a second network number, as well as a first network voice mail. A call directed to the first network number (50) of the communications unit is forwarded to the second network number (52) of the communications unit when the communications unit is not operating in the first network. A first network voice mail number (P3) may be associated with calls so that calls are forwarded directly to the first network voice mail (56) when received again at the first network (54). Alternatively, if a call is subsequently received from the second communications network, and data of the subsequently received call matches data of the initial call, or if call forwarding indicia associated with the forwarded call is also associated with the subsequent call, the subsequent call is then forwarded to the first network voice mail of the communications unit.
