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.

6. A message transmission method in a system including a plurality of devices connected by a network and a server transmitting messages using addresses of individual users of the devices as destinations, wherein:
-
the server also handles a group address of a group composed of one or more of the individual users as the destination, and when a message transmission request designating the group address as the destination is received, the server carries out the message transmission using addresses of the individual users included in the group as the destinations, and when a message transmission request designating two or more group addresses as the destinations or a message transmission request designating one or more group addresses and one or more addresses of individual users as the destinations is received, the server checks whether or not there exists an address of an individual user redundantly included in the destinations of the message regarding the message transmission request and thereby transmits the message to the destinations avoiding redundant transmission of the message to the same address. - View Dependent Claims (7, 8)
