Abstract
A method of updating accumulated data with communication middleware and a server system capable of maintaining real-time characteristics for information and improving efficiency of a line is provided. Router side communication means and LAN side communication means perform control for communication on a LAN. Router side and LAN side buffer managing means perform management and notification for data transmitted and received on a radio network side and LAN side in a buffer. Communication continuing means executes processing for connection/reconnection to a client and acknowledgment for sending data packets as well as performing retransmission control and sequence control for application data when a line is disconnected. Also, communication continuing means determines whether data which has not been transmitted is new or old based on update information notified by data update monitoring means and prompts the client to update data. Data update monitoring means monitors data update information sent from an application server and notifies communication continuing means of the information.
