A network agent system and the corresponding realizing methods based on instant communication platform

The invention relates to a network agent system based on an instant communication platform, which adds an agent module on the client of an instant communication system, and correspondingly, another agent module is added on the server of the instant communication system. Compared with the common instant communication system, the main change of the system is that the agent module is added on the client, and the agent module provides the function of establishment and discovering of the agent. Correspondingly, the instant communication server also expands the related operational function of the agent, which not only takes charge of the interaction of the agent information of the user, but also processes the decisions and statistical information related to the agent, such as the flow of the content, the rate of the network, etc. A method which is used for realizing network agent system and based on instant communication platform consists of two basic processes; the two basic processes respectively relate to the basic process used for establishing and providing agent service for the user and the basic process used for leading the user to successfully discover and use the agent service.
