Abstract
Abstract A two-way wireless messaging system has a cellular network with a mobile switching center for routing messages to base stations, a home location register for storing profiles and a home location register for storing profiles and location information, and a messaging center for receiving, storing and forwarding messages. In the present invention, a set of modular servers is added to add network based message expansion, transaction tracking, directed paging, and user defined services in an incremental fashion.

Claim 1
Independent Claim
167 words
A two-way wireless cellular messaging system comprising a cellular network having a mobile switching center and a home
location register for storing profiles of mobile messaging entities that receive a message
expanded from a message code generated by a messaging agent and for registering any on-line
mobile messaging entities, a user agent associated with the home location register and
corresponding to a subscriber of the messaging system for storing a plurality of destination
addresses and messages to be expanded corresponding to a message code that is received
from a messaging agent or mobile messaging entity, and a messaging center for receiving and forwarding a message code
generated by a messaging agent to the user agent for subsequent message expansion
corresponding to a stored message, and for querying the home location register to
determine the location of a mobile messaging entity that has registered, and forwarding a
message to a mobile switching center after receiving a routing address for the message for
subsequent delivery to a desired destination.
