Method and system for transmitting messages to terminal groups

摘要

Method and system for transmitting e.g. SMS messages from individual user terminals (1) to terminal groups under control of a message server (3) having various network ports (x,y,z) and a group register (5) for registering, under control of a server processor (6), for each group of terminals a group identifier and the relevant terminal addresses and one of the server's network ports. The port is selectedthus that the combination of the terminal's network address and the server's network port is unique. On receiving a message from a calling terminal, the combination of the server port called by the terminal and the calling terminal's network address is matched with the combinations registered in the group register, resulting in one valid terminal group. Copies of the received message are transmitted to the network addresses of the matching SMS groups.
