Preferred network selection
First Claim
1. A remote preference unit for influencing visited network selection by roaming mobile units making roaming registration attemps, the preference unit comprising:
- a detection unit for detection of roaming activity by mobile unitsa database indicative of preferred networks for selection by roaming units, andan output unit, associated with said detection unit and said database to output indications to influence network selection by said detected roaming mobile units,wherein said output indications are rejection signals to roaming registration attempts to respective non-preferred roaming networks, and said roaming registration rejection signals are sent to location infrastructure of respective non-preferred roaming networks, thereby to cause a roaming registration attempt to fail at said non-preferred network and force said mobile units to re-attempt roaming registration, thereby at said reattempting to select a preferred roaming network.

Abstract
A remote preference unit for influencing visited network selection by roaming mobile units, comprises a detection signaling relay/probe on International signaling connections, for detection of roaming activity by mobile units, a database indicative of preferred networks in the given country that the network operator prefers his roamers to use, application logic with certain criteria, determining the output, and an output unit, associated with said detection probe and said database to output indications to influence network selection by said detected roaming mobile units. In one embodiment the output is simply a rejection of the location update signal that forms the roaming request. In an alternative embodiment the signal is a copy of the relevant section of the database which is uploaded to the SIM card of the roaming unit. The SIM card upgrade may or may not be accompanied by a stage of forcing the handset to re-initiate the network selection process.
