  • Patent number: 8548500
    Abstract: Techniques for supporting location services with roaming are described. A method of supporting location services (LCS) for a mobile station roaming from a home network and communicating with a visited network includes receiving a domain name system (DNS) query at a DNS of the home network from a packet data serving node (PDSN) of the home network. The method also includes sending to the mobile station from the DNS of the home network an address of a serving position determining entity (S-PDE) in the visited network.

  • Patent number: 8504064
    Abstract: Techniques for supporting location services (LCS) with roaming are described. A method of supporting LCS in a network comprising a Secure User Plane Location (SUPL) enabled terminal (SET), a home SUPL location center (H-SLC), and a serving SUPL location center (S-SLC) includes receiving, at the H-SLC, a location request message for a location of the SET, where the location request message comprises an indication of a network location of the SET. The method includes sending, to the S-SLC in response to the location request message, a roaming request message. The method includes receiving, from the S-SLC in response to the roaming request message, a location report message comprising a position of the network location. The method also includes sending a reporting message comprising the position of the network location of the SET as the location of the SET.

  • Patent number: 8185128
    Abstract: Techniques for supporting location services with roaming are described. A mobile station interacts with a home mobile positioning center (H-MPC) in a home network for location services even when roaming. The mobile station communicates with a visited network for a data session and receives a request for its location. The mobile station sends first information (e.g., SID and NID) indicative of its current network location to the H-MPC. The H-MPC determines a serving mobile positioning center (S-MPC) in the visited network based on the first information. The S-MPC determines a serving position determining entity (S-PDE) in the visited network based on the first information. Depending on the selected positioning method, the H-MPC may receive an S-PDE address or a position estimate of the mobile station from the S-MPC and may forward this information to mobile station. The mobile station may communicate with the S-PDE for positioning using the S-PDE address.

  • Patent number: 7609626
    Abstract: Traffic demands are routed across links of an information network so as to avoid congestion and allow for future traffic growth. Traffic demands from a source node to a destination node of the network are monitored, including bandwidths associated with each of the demands. For each demand, and for a given link of the network, that portion of the bandwidth associated with each traffic demand which is provided by the given link, is determined. A maximum value of link utilization among all links of the network is then determined, wherein link utilization is defined as the amount of bandwidth used by all traffic demands routed through a given link with respect to a total capacity of the link. Traffic demands are then routed across the links of the network in such a manner as to minimize the maximum value of link utilization.

  • Patent number: 7426179
    Abstract: A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration.

  • Patent number: 7088920
    Abstract: A method is provided for establishing a service connection between first and second network nodes in a WDM optical network for a plurality of network users. The method begins by receiving, from each network user, user-preferences prioritizing a plurality of decision criteria defining preferable characteristics of the service connection. Next, a prescribed algorithm is used to select a path and a channel wavelength at which information is to be conveyed over the path between the first and second nodes. The selection is based on the plurality of decision criteria as prioritized in accordance with the user-preferences. Finally, the first and second network nodes are interconnected over the selected path with the selected channel wavelength.
