System and method for delivery of short message service messages to a restricted group of subscribers
First Claim
1. A telecommunications system for controlling the display of a short message on a plurality of mobile terminals, said telecommunications system comprising:
- a base station in wireless communication with said plurality of mobile terminals, said base station broadcasting said short message, said short message having first and second headers encapsulated therein, said first header including a private indicator indicating that said short message is intended only for a particular group of said plurality of mobile terminals, said second header including a particular one of a plurality of group identification codes, said particular group identification code being associated with said particular group of mobile terminals, a given one of said mobile terminals receiving said short message from said base station;
a memory, within said given mobile terminal, for storing a list of said group identification codes that said given mobile terminal is associated with; and
comparison means within said given mobile terminal for comparing said received particular group identification code with said list of group identification codes associated with said given mobile terminal, said short message being displayed on said given mobile terminal when said received particular group identification code is within said list of group identification codes.

Abstract
A telecommunications system and method is disclosed for encapsulating header information associated with a Short Message Service (SMS) message within that SMS message, which can then be sent over a broadcast channel. This header information can contain, for example, additional information regarding the intended recipients of the SMS message. For example, a business with 100 employees may want to be able to broadcast a SMS message to all employees, but not to anyone else. Therefore, in this case, the header information can indicate “private” and include a unique user group identification (ID) code. A Subscriber Identity Module (SIM), or other memory, within each of the mobile terminals within the predefined group can contain a message application, which can compare the received group ID to a group ID stored in the SIM, and determine whether the message should be displayed on the mobile terminal.
