Method and system for directing a data message in a wireless communications network including multiple wireless systems
First Claim
1. A system for directing a data message in a hybrid communications network, including a first wireless system and a second wireless system, the system comprising:
- a central database, independent of the first and second wireless system, the central database configured to send update information to update a user profile in the first wireless system in response to service for a mobile station being transferred from the first wireless system to the second wireless system, the user profile being updated to indicate that data messaging services are being provided to the mobile station by the second wireless system based on received transfer information, the transfer information including deregistration information from the first wireless system, wherein the first wireless system is one of a private and a public wireless system, and if the first wireless system is a private wireless system, the second wireless system is a public wireless system, and if the first wireless system is a public wireless system, the second wireless system is a private wireless system; and
a service node for directing a data message for a mobile station through the second wireless system, as facilitated by the updated user profile, to deliver the data message to the mobile station during its operation on the second wireless system.

Abstract
A mobile station scans for electromagnetic signals representing control channels of the public wireless system and the private wireless system. The mobile station measures a received signal parameter of at least one of the scanned control channels. The hybrid communications network may transfer the mobile station'"'"'s service from the public wireless system to the private wireless system, if the measured signal parameter meets or exceeds a private target. Alternately, the hybrid communications system may transfer service from the private wireless system to the public wireless system, if the measured signal parameter meets or exceeds a public target. A service control point maintains a central database of user profiles updated in response to the transferring procedure. A service node redirects a data message for the mobile station through the public wireless system or through the private wireless system, as facilitated by the central database, to deliver the data message to the mobile station during its operation on an active one of the wireless systems.

7. A method of managing data messages, comprising:
-
sending deregistration data including at least one of a mobile switching center identifier and a cell identifier from a first wireless system to a central database based on a mobile station transferring from the first wireless system to a second wireless system, the central database being independent of the first and second wireless system and being a database for indicating which wireless system provides data messaging services for the mobile station; receiving update information for the mobile station from the central database, the update information including an identifier of the second wireless system; and updating a user profile of the mobile station in at least one of a home location register and a visitor location register based on the received update information, the user profile being updated to indicate that the second wireless system provides data messaging services to the mobile station, and wherein the first wireless system is one of a private and a public wireless system, and if the first wireless system is a private wireless system, the second wireless system is a public wireless system, and if the first wireless system is a public wireless system, the second wireless system is a private wireless system. - View Dependent Claims (8, 9, 10, 11)
