Abstract: An embodiment is a method for support of retrieval and/or reporting and/or triggering the reporting of user location information in a mobile network, wherein said user location information is retrieved and/or reported and/or the reporting of said user location information is triggered, at a granularity of an area referred to as administrative area defined as a set of mobile network related areas, mobile network related areas being defined at mobile network management level, and mobile network related areas being mapped to administrative areas.

Abstract: Avoiding duplicative forwarding of multicast traffic is disclosed. A join message received at a first router is directed to a peer router of the first router from a first downstream node of the first router and the peer router without passing through the peer router. The join message indicates that one or more downstream nodes of the peer desire to receive from the peer multicast traffic specified in the join message. It is determined whether the join message from the first downstream node to the peer would result in duplicative forwarding by the peer of multicast traffic from an upstream source upstream of the peer and the first router based on the join message. Based at least in part on a determination that the join message would result in duplicative forwarding of the multicast traffic, an election procedure is initiated to avoid such duplicative forwarding of the multicast traffic.

Abstract: Virtual connection route selection apparatus and techniques are disclosed. At a communication traffic routing apparatus, metric information associated with multiple different routes for a virtual connection, such as a PseudoWire, toward a destination is collected. The metric information may be collected from one or more remote route computation elements capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, or during actual establishment of the virtual connections, for example. An initial or re-optimized route for a virtual connection can then be selected at the routing apparatus based on the collected metric information. In some embodiments, although the virtual connection routes are paths computed by Path Computation Elements (PCEs), actual path selection decisions are distributed to routers.

Abstract: An UMA network controller (SGW, CM) is dedicated for an UMA mobile network comprising a CS core network (CN2) and a PS core network (CN1) with a SGSN. This UMA network controller comprises a security gateway (SGW) and a control means (CM) coupled one to the other. The security gateway (SGW) is arranged i) to ensure security procedures between mobile stations (MS) and the UMA world, ii) to forward messages relative to the control plan for the packet switched core network (CN1) between mobile stations (MS) and the control means (CM), and iii) to forward messages relative to the user plan for the packet switched core network (CN1) between mobile stations (MS) and the serving GPRS serving node (SGSN). The control means (CM) is intercalated between the security gateway (SGW) and the serving GPRS serving node (SGSN) and arranged for handling the control plan for the packet switched core network (CN1).
