The method, system, and device for transmitting an MIH message described herein provide flow controls for the MIH message transmission, thereby enhancing the transmission efficiency of the MIH message.10-08-2009
20090318147METHOD AND COMMUNICATION SYSTEM FOR STORING ADDRESS OF NETWORK ANCHOR POINT TO NETWORK SERVER - A method for storing an address of a network anchor point to a network server is provided The provided method includes the following steps: a terminal initiates an attach request or a bearer establishment request, and a network selects a network anchor point; and when the network anchor point assigns a first bearer context to the terminal, or a first connection is established between the network anchor point and the terminal, the network registers an address of the network anchor point to a network server. A method for deleting an address of a network anchor point from a network server is also provided, which includes the following steps: when a terminal or an entity in a network initiates a delete bearer request, the network instructs a network server to delete an address of a network anchor point that has been registered to the network server if the network anchor point no longer serves the terminal; and the network server deregisters the address of the network anchor point. A communication system is further provided.12-24-2009
20100008373COMMUNICATION SYSTEM, DEVICE, METHOD FOR HANDING OVER A ROUTE AND METHOD FOR NOTIFYING A STATE OF ADVERTISING A LABEL - The present invention relates to a field of communication technology, and more particularly to a communication system, a label switched router, a network device, a method for handing over a route, and a method for notifying a state of advertising a label so as to improve an accuracy occasion for handing over a route. A liberal LSP between an upstream LSR and a downstream LSR is established; it is confirmed that establishing the liberal LSP is accomplished; a handover notification is sent to the upstream LSR; and the upstream LSR hands over the route according to the handover notification. By adopting such technical solution, the accuracy occasion for handing over the route is improved so as to avoid label forwarding interruption, and reduce the influences on the convergence time of handing over the route.01-14-2010
20100058027METHOD FOR SELECTING HASH FUNCTION, METHOD FOR STORING AND SEARCHING ROUTING TABLE AND DEVICES THEREOF - A method for selecting a hash function, a method for storing and searching a routing table and devices thereof are provided.
