摘要： A routing system utilizes a layer 2 switch interconnecting several routers to intelligently forward multicast packets throughout an interne exchange carrying multicast content. The layer 2 switch performs protocol snooping to extract a lookup key that is based on network layer protocol information. The lookup key is uniquely formulated to support either shared or explicit source distribution trees. The lookup key is used to query a forwarding memory that returns an outgoing port index. The outgoing port index points to one or more outgoing ports that are eligible to receive the multicast packet. The outgoing ports are also connected to the neighboring device(s) that are designated to receive the multicast packet. The routing system also supports real time maintenance and updating of the forwarding memory based on the periodic exchange of control messages. The routing system is configured to support PIM routers operating in PIM SM or PIM SSM modes. However, the routing system can also support other multicast protocols and/or standards.

摘要： Methods and apparatus for supporting emergency communications are provided. A method for a Radio Access Network (RAN) serving at least one Core Network (CN) to support emergency communications of a User Equipment (UE) includes determining whether at least one CN in a shared network environment supports emergency communications, if it is determined that the at least one CN in the shared network environment supports emergency communications, transmitting an emergency call support indication to the UE indicating that emergency communications are supported, receiving a request for emergency communications from the UE, and routing the request for emergency communications to another CN that supports emergency communications in the shared network environment, if a given CN does not support emergency communications.

摘要： The present invention provides a method and system for communicating physical cell identifier information to mobile stations. In one embodiment, a method includes detecting a need to change a physical cell identifier associated with a cell in a telecommunication network used for serving the mobile station. The method also includes communicating physical cell identifier information to the mobile station based on the detected need to change the physical cell identifier. The method includes employing another physical cell identifier associated with the cell based on the communicated physical cell identifier information. The physical cell identifier information is communicated in one or more modification periods such that said another physical cell identifier is employed by the base station and the mobile station at a boundary of one of the modification periods. Moreover, the method includes continue serving the mobile station based on the employed said another physical cell identifier.
