Abstract:
PROBLEM TO BE SOLVED: To make possible a communication of an encrypted identification number without increasing a burden for a user of a subscriber unit and without making excessive delay occur in the start of service. SOLUTION: In the messaging method, a messaging key associated with a subscriber unit reference number is imparted to a subscriber unit (105) and an infra-communication center (101) (203, 403). Next, an identification key and/or an identifier of the subscriber unit (105) is generated by either the subscriber unit (105) or the infra-communication center (101) (300, 407). The identification key and/or the identifier is encrypted with the messaging key (207, 413) and next communicated between the subscriber unit (105) and the infra-communication center (101) (209, 415).

Abstract:
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 an HLR (124) to a D-VLR (126), authenticating (30 6) 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 gatewa, and establishing (312) a packet data link between the mobile data gateway and the mobile station.

Abstract:
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, 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) is forwarded to the second network number (52) 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 at the first network (54). Alternatively, when a call is subsequently received from the second communications network and data of the subsequently received call matches data of the initial or forwarded call, the subsequent call is forwarded to the first network voice mail.
Abstract:
A wireless communication unit (101, 200, 401), network switch (112, 300, 407) and corresponding methods facilitate retrieval, routing, and management of on-hold calls (FIG. 4 - FIG. 7) within a first communication network (103) when the unit is operating in a second communication network (105) that is loosely coupled to the first. The communication unit comprises a transceiver (203) configured to support an air interface with the first and the second communication network; and a controller (209) arranged to cooperatively operate with the transceiver to retrieve an on-hold call from the first network via a call leg established to support a handout to and while the unit is operating in the second network. A user interface (211) and in band signaling over the call leg facilitates management, connecting, disconnecting, etc., of the on-hold calls by the communication unit.
