Abstract: In embodiments of the disclosed technology, devices and methods for redirecting a telephone call from a public-switched telephone to a packet-switched data network. The phone call is initially received via the public-switched telephone network having a dialed number associated with a hand-held wireless device of a called party. Upon initialization of the phone call, a route is determined from the telecommunications switch to the hand-held wireless device of the called party via a packet-switched network. The bandwidth of the packet-switched network is then detected to determine the ability of the network to handle the call. If the packet-switched network is determined to be capable of handling the call, the call is forwarded over the packet-switched data, thereby reducing or eliminating charges for wireless minutes.

An E.164 number is associated with the call information in the first SIP Invite request and a SIP response including the E.164 number is sent to the UE device in response to receiving the first SIP Invite request. When a call setup message including the E.164 number received from the CS network, the received E.164 number is verified if it is valid and if so, the call information is identified based on the E.164 number and is sent to the called party via a second SIP Invite request.

Abstract: A server, upon receiving a request to complete a call over a packet-switched network, looks up an address on the packet-switched network on a local table. If the local table does not contain a matching address, the server asks a routing server to identify a receiving server address. The routing server identifies a suitable address and sends a message to the originating server containing the address. The receiving server then receives, via the packet-switched network, a message requesting a telephone connection to a second telephone device. Before completing the connection to the second telephone device, information in the message representing the address of the device on the packet-switched network that originated the message is identified and the address information is compared to selected predetermined addresses for permitted origins of the message.

Thus, wireless carriers may continue signaling the way they are today, i.e., using the J-STD-036 standard for CDMA and GSM in North America, yet see benefits of a VoIP network core, i.e., provision of MSAG quality location data to a PSAP.

Abstract: Various techniques can be used to handle frames within multi-stage switching fabric. For example, in one method, a frame and an associated frame header are received at a switching fabric stage. The associated frame header includes a first field and a second field. The method selects one or more fabric points of exit within the switching fabric stage, based on the second field. The first field is used to select one or more other fabric points of exit within another switching fabric stage, and thus two different fields within the associated frame header specify fabric points of exit. The method then sends the frame to the selected fabric points of exit within the switching fabric stage.

The session request comprises a request to establish a communications session between the first subscriber and a second subscriber. In the event the session request originated in a trusted network, the first network component permits access to unique resource identifier (URI) information associated with the second subscriber for use in establishing the communications session via the packet-based network. In the event the session request did not originate in a trusted network and in response to determining a security configuration associated with the second subscriber allows the first subscriber to access the URI information under the circumstances, the first network component permits access to the URI information for use in establishing the communications session via the packet-based network.

Abstract: The present invention relates to providing services for circuit-switched calls from an Internet Protocol (IP) based packet network. In essence, a call originating from or intended for a subscriber that is served by a telephony switch, such as an end office or mobile switching center, in a circuit-switched network is intercepted and routed by the telephony switch to a service node via a subscriber emulator. The subscriber emulator acts as a liaison between the telephony switch of the circuit-switched network and the service node of the packet network. Preferably, the subscriber emulator presents itself to the service node as a user agent, which acts on behalf of a subscriber that is served the telephony switch. The service node provides any requisite processing of the call to implement services for the call.

In this regard, an ingress lookup operation in a first physical device of one embodiment produces information which is used by the switching fabric in a different physical device to forward a packet to the appropriate egress line card in the different physical device.

The routing protocol daemon sends the link state message from the network device to another network device of the network in accordance with a routing protocol.

Abstract: A vehicle network link module includes network fabric ports, a port, a switching circuit, and a link manager. The network fabric ports are operable for coupling to corresponding network fabric ports of another vehicle network fabric link module. The port is operable for coupling to a port of a vehicle network module. The switching circuit is operable to connect an active network fabric port to the port. The link manager determines whether vehicle network packet conveyance via the active network fabric port has degenerated below a threshold. When the vehicle network packet conveyance has degenerated below a threshold, the link manager determines use mode of the active network fabric port. The link manager processing module then selects a new active network fabric port based on the use mode. The link manager then activates the new active network fabric port for coupling via the switching circuit to the port.

Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

A voice call establishment for a terminal using first the most recent domain which is used for a voice call in a mobile communication system is initiated. Thus, it is possible in a mobile communication system to increase the domain selecting completion rates for a voice call service corresponding to a terminal.

Abstract: A method of providing a message service in a sender's wireless device is disclosed. The sender's wireless device may be capable of sending messages via a packet switched base station in a first mode, or via a short message service (SMS) base station that is independent of the packet switched base station, in a second mode.

If the destination address does not correspond to a subscriber of the service, the outgoing message may be sent via the SMS base station in the second mode.

Abstract: A telecommunications addressing system/method allowing selection of a telephone instrument device (TID) using arbitrary identifiers is disclosed. The system/method allows a source TID (STD) to select a target TID (TTD) by the use of a Target Telephone Identifier (TTI) data string rather than a traditional numeric telephone identification (NTI). This TTI is then indexed within a TTI/NTI mapping server (TMS) that functions as a hierarchical repository of TTI/NTI mappings. STD/TTD communication is established by first performing a lookup of the STD-selected TTI within the TMS to identify the NTI of the TTD. Once the NTI of the STD has been identified by the TMS, communication between the STD and TTD is established using the NTI via the normal public switched telephone network (PSTN). TMS TTI lookup may be performed via STD TID web application and/or via PSTN infrastructure interface.

In the event of such a need, a routing default is established and/or an existing routing default is changed in a gateway device.
