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.
