The received SIP message is protocol translated to generate a non-IMS message including the web service request. The non-IMS message is conveyed to a web service provider, and a requested web service corresponding to the non-IMS message is conveyed from the web service provider to the device. The SIP message may include a SIP INVITE message containing an embedded SOAP message.

Abstract: A given router in the core of a label-switching network identifies a group of routers to receive common label binding information for later routing packets along respective paths through the label-switching network. One way to identify which of multiple routers to include as a member of the group to receive the same label information is to analyze egress policies associated with downstream routers in the label-switching network. Based on this analysis, the given router identifies group members as routers having a substantially same egress policy as each other. The given router then allocates memory resources to store a common set of label information to be distributed to each member in the group of routers having the same egress policy. After populating the memory resources with label information, the given router distributes a common set of label information to each router in the group of routers.

In the latter case, a lack of beacon transmissions by other wireless devices in the ad hoc network may be indicated by the transmission of a relatively large number of beacons in succession by a wireless device.

Abstract: Combinational networks may provide simultaneous connectivity over networks of different type between terminals. Communication sessions on different network types such as Circuit switched and Packet switched, belonging to the same user equipment can be correlated. In case a communication session on a circuit switched network is halted by a supplementary service e.g. at an event such as acceptance of Call Hold, a communication session on a correlated packet switched network should be halted as well. A user equipment that detects the event sends a halt message to the circuit switched network and a message to the packet switched network or a session state manager node. The session state manager node either forwards the halt-message to the packet switched network, or sends a halt-message to the packet switched network when the packet switched network does not notify that a halt has occurred.

Abstract: An exemplary method and apparatus provide improved dormant handoff of mobile stations having multiple packet data service instances. Each time a dormant IS-2000 mobile station undergoes a packet data mobility event it sends a dormant handoff request to the supporting network for each packet data service instance associated with it. If the mobile station does not have a traffic channel already assigned to it, each dormant handoff request are sent over common access channels. By recognizing that a given mobile station is re-registering multiple service instances for the same mobility event, the network can avoid excess common channel signaling by assigning a traffic channel to the mobile station responsive to receiving the dormant handoff request for its first service instance. Such an assignment causes the mobile station to send dormant handoff requests for any remaining service instances over the assigned traffic channel rather than over the common access channel.

Abstract: The Fibre Channel standard was created by the American National Standard for Information Systems (ANSI) X3T11 task group to define a serial I/O channel for interconnecting a number of heterogeneous peripheral devices to computer systems as well as interconnecting the computer systems themselves through optical fiber and copper media at gigabit speeds (i.e., one billion bits per second). Multiple protocols such as SCSI (Small Computer Serial Interface), IP (Internet Protocol), HIPPI, ATM (Asynchronous Transfer Mode) among others can concurrently utilize the same media when mapped over Fibre Channel. A Fibre Channel Fabric is an entity which transmits Fibre Channel frames between connected Node Ports. The Fibre Channel fabric routes the frames based on the destination address as well as other information embedded in the Fibre Channel frame header. Node Ports are attached to the Fibre Channel Fabric through links.

For an originated communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides consistency with the specific format required by the receiving party.

The TempENUM database stores a TempENUM from a coordinator system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication the initial caller.

Abstract: When voice over Internet Protocol (IP) capabilities are added to a conventional network of voice switches, an IP network is normally used to replace individual trunks between voice switches and to replace telephone lines between telephones and their serving voice switches. As a result, calls across the upgraded network often pass across a series of IP hops. Accordingly, the problem of replacing a series of IP hops by a single hop, to avoid degradation of end-to-end voice quality due to repeated packetization/depacketization sequences and associated functions such as compression/decompression, is addressed.

In response to determining that the difference between the stored IP address and the IP address indicated by the received message indicates a change in geographic location of the portable IP communications device, a subscriber is prompted to update stored geographic location information for providing E911 service to the subscriber.
