Abstract: The hybrid mobile terminal is engaged in an existing call through a serving one of a circuit switched or packet data wireless networks. The mobile terminal places a new call through the target one of the wireless networks, the new call having a predetermined called party identifier. In response to the called party identifier, the call is converted to a loop-back call directed to the mobile terminal through the serving wireless network, establishing a call path through the target wireless network. The mobile terminal accepts the loop-back call, and directs the existing call to connect to the call path through the target wireless network. The existing call through the original network is then dropped, effecting an inter-system handoff from the serving to the target wireless network.

Abstract: An access node anchoring a connection to, e.g., a PDSN in a core network establishes a session with a mobile station and assigns the mobile station an identifier such as a UATI. The anchor node sends the UATI to the PDSN, such as in a GRE key where the data link is a GRE tunnel. If the anchor node fails and data addressed to the mobile station comes to the PDSN, it may initiate a page for the mobile using the UATI. The anchor node may additionally send the PDSN the session seed and optionally the mobile station's network location. A registration zone may be defined to include access nodes within a predetermined distance of the anchor node, and the mobile station forced to re-register when moving outside of the registration zone. In this case, the PDSN may initiate a page for the mobile station only within the registration zone.

Abstract: A base station in a wireless communication network saves connection information that enables it to recognize currently authenticated mobile stations. The base station carries out localized connection management processing for authenticated mobile stations, at least for certain types of packet data connection events. By carrying out localized processing, the base station skips the connection management signaling between it and a supporting mobile switching center that would otherwise be required for processing such events. Thus, in a cdma2000 base station embodying such localized processing, the MSC's involvement in packet data connection state transitions, short data burst deliveries, etc., can be eliminated or at least greatly reduced, thereby minimizing the MSC's role in supporting packet data services.

Abstract: A mobile station serves as an aggregation point for connecting one or more peripheral devices to a Public Data Network through the mobile station's wireless link to a supporting wireless communication network. In an exemplary embodiment, the mobile station establishes a single PPP session with the network that includes a primary service instance for itself and an auxiliary service instance for each locally attached peripheral device. As such, the mobile station and the one or more locally attached peripheral devices share a single PPP session, permitting each device to have its own IP address and allowing the mobile station to provide Mobile IP messaging relay between Mobile IP clients in the attached devices and the supporting network. With this arrangement, the mobile station avoids IP packet routing overhead by directing traffic to the appropriate peripheral device using the service instance identifiers marking the packet data traffic received from the network.

Abstract: A wireless local area network authenticates access by a user's device utilizing an authentication key provisioned in another of the user's devices. The network transmits a challenge to the non-provisioned device. The non-provisioned device forwards the challenge to the provisioned device across a wire-based or wireless interface connecting the two devices, such as a BLUETOOTH network link. The provisioned device calculates a response using the authentication key, and forwards the response to the non-provisioned device. The non-provisioned device then transmits the response to the wireless local area network for authentication.

Abstract: A wireless mobile terminal is alerted to the presence of an available Wireless Local Area Network by a communication network, based on the location of the mobile terminal. The mobile terminal alerts a wireless computing device, either via a wired or wireless interface, or by paging the user. Alternatively, the mobile terminal and the wireless computing device may form an integrated unit with interfaces to both the WLAN and the communication network. The wireless computing device initiates a scan for the WLAN, or logs onto the WLAN based on information transmitted to the mobile terminal. When the user is not in the range of a WLAN, the wireless computing device conserves battery power by not scanning for a WLAN. The communication network may additionally be connected to the WLAN for data exchange. The alert criteria may be customized and stored in a subscriber database at the communication network.
