US 7,610,343 B2 · Presence data management method

Abstract

The amount of data of presence information delivered from a presence server to a terminal is reduced by letting the presence server discard part of the presence information depending on communication measures and data type available to the terminal, by which the amount of data processed by the terminal is reduced. The presence server fetches terminal information stored therein based on terminal information contained in a presence inquiry request message from a user and thereby learns the type of data that can be processed by the terminal of the user. The presence server reconstructs the presence information of a referred user into information that can be processed by the terminal, and sends the information to the application of the terminal. By reducing the amount of presence data transmitted from the presence server to the terminal, the amount of data to be processed by the terminal can be cut down.
