Abstract
In a short message service (SMS) wireline/wireless message system, a separate SMS exchange subsystem implements value-added service capability. The value addition service may range, for example, from simple data insertion in the SMS message to the more complex initiation of a teleconference call using inter-exchanged SMS messages.
