    • An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed IP connection, and mobile network IP connection. By using this apparatus of the present invention, cost can be reduced and upgrading to advanced access networks and access services is easily carried out. Provision of the above access nodes implements upgrade-type network services common for diverse protocols. Each access node retains a pathfinding table to which input port, input tunnel identifier and input session identifier entries in a set are registered per session. When routing a packet, by looking up the set of these entries matching with the packet, the associated output port, output tunnel identifier, and output session identifier are obtained. After processing for the packet, appropriate for one of the plurality of access methods and network services, the node forwards the packet over the routed path.
    • 作为分组交换装置运行的接入节点能够实现多种接入方式的IP连接业务; 例如,相对低速的IP连接,高速IP连接和移动网络IP连接。 通过使用本发明的装置,可以降低成本,容易地进行高级接入网和接入业务的升级。 上述接入节点的配置实现了各种协议通用的升级型网络服务。 每个访问节点保留路径寻找表,每个会话向其注册一个输入端口,输入隧道标识符和一组中的输入会话标识符条目。 当路由数据包时,通过查找与数据包匹配的这些条目的集合,获得相关联的输出端口,输出隧道标识符和输出会话标识符。 在针对分组的处理之后,适于多个接入方法和网络服务之一,节点通过路由路径转发分组。

    • A scheme and a device for managing a user state and a plurality of terminal states on a presence server, and for automatically selecting an optimum terminal by using both the user state and the terminal states. Priority degrees which depend on the terminal states are set, then selecting a terminal whose priority degree is the highest of the plurality of terminals. In association therewith, a priority rank which is set depending on the user state is also taken into consideration, thereby selecting a final optimum terminal. The present scheme makes it possible to automatically perform a fine-grained selection of the optimum terminal in which both the terminal states and the user state are taken into consideration.
    • 一种用于在存在服务器上管理用户状态和多个终端状态并且通过使用用户状态和终端状态来自动选择最佳终端的方案和设备。 设定依赖于终端状态的优先级,然后选择优先度为多个终端中最高的终端。 与此相关联,还考虑了根据用户状态设置的优先级,从而选择最终最优终端。 本方案使得可以自动执行考虑终端状态和用户状态两者的最佳终端的细粒度选择。
