    • PURPOSE: A method for controlling a session in a diameter-based mobile Internet protocol network is provided to use session information including a session ID(IDentication) as an indicator of a diameter session and a session state of a subscriber for processing a message stably and process a request for setting and canceling the session according to an address request type of a visitor subscriber/a home subscriber. CONSTITUTION: When starting, a diameter server initializes session information and stores each session state as an idle state(301). After the initialization of the session information, a socket is produced for exchanging information with connected opponents' nodes(302). Thereafter, information on agents connected to the diameter server is collected(303). After waiting messages transmitted from opponent system information, kinds of messages capable of being received by the diameter server are discriminated(304). According to kinds of messages which can be received, diameter messages, AMR(AA-Mobile-Node-Request) message, AMA(AA-Mobile-Node-Answer) message, HAR(Home-Agent-MIP-Request) message, HAR(Home-Agent-MIP-Request) message, HAA(Home-Agent-MIP-Answer) message, STR(Session-Termination-Request) message, STA(Session-Termination-Answer) message, and STI(Session-Termination-Ind) message for applying a mobile IP(Internet Protocol) are processed respectively(305-311).
    • 目的:提供一种用于控制基于直径的移动互联网协议网络中的会话的方法,以使用包括会话ID(IDentication)的会话信息作为用户的直径会话和会话状态以稳定处理消息的指示符, 根据访客用户/归属用户的地址请求类型处理设置和取消会话的请求。 构成:启动时,直径服务器初始化会话信息并将每个会话状态存储为空闲状态(301)。 在会话信息的初始化之后,产生用于与连接的对手的节点交换信息的套接字(302)。 之后,收集关于连接到直径服务器的代理的信息(303)。 在等待从对手系统信息发送的消息之后,区分(304)直径服务器能够接收的消息的种类。 根据可以接收的消息的种类,直径消息,AMR(AA-移动 - 节点 - 请求)消息,AMA(AA-移动 - 节点 - 应答)消息,HAR(家庭代理-MIP-请求)消息,HAR (家庭代理MIP-请求)消息,HAA(家庭代理-MIP-应答)消息,STR(会话终止 - 请求)消息,STA(会话终止 - 答复)消息和STI(会话终止 - Ind)消息分别被处理(305-311)。
