In mobile computing environment, the wireless communication disconnect at times and mobile clients move frequently, that's where the shoe pinches for using the technology of conventional wired networks and distributed system to mobile computing system.Based on wireless access network, we propose a technology of agent-cache which is fit for a mobile computing environment with the architecture of‘Client/Agent/Server’ in this paper. We use the artifice of agent-cache to reduce traffic and take some proper control to avoid dirty data been read by one. Our content includes that user data can be updated in time by virtue of validating the consistency of data among the client, agent and server. A new Callback Validating Policy is presented by us for mobile environment because the current arithmetic for this is believed with the problem of writing delay, in which the cache data need be revalidated again when any client appears.Manage client’s cache and transmit failed data, the agent harmonizes and simplifies the relationship between a mobile client and a server. Then the problems which come from mobility, disconnection and writing delay can be abated distinctly.
