Two-way interactive short message system with personalized messaging menus
that provide WAP like services at less cost than CSD. Mobile Originated
Interactive Menus are implemented as a feature of a Short Message Service
Center (SMSC). Each option guides either to the next menu level, or to a
final action to be executed according to the path followed by the
subscriber. Importantly, the mobile originated interactive menus use SMS
communications instead of circuit switched data (CSD) (e.g., instead of
WAP communications), thus leaving traffic channels available for voice
calls. Users may define the content and frequency they want. Replacement
of messages in TDMA and GSM mobile devices allow for heavy usage without
filling up the user's phone buffer, i.e., prior messages may be
overwritten, to assure that only the latest information is all that is
being displayed and read.
