Methods and arrangements for controlling re-registration of a mobile communications station based on satellite call optimization
First Claim
1. An arrangement for use in a mobile communications network, the arrangement comprising:
- a master controller comprising subscriber information about a mobile station;
the mobile station being configured to selectively attempt to register with at least one of a plurality of gateways within a mobile communications network; and
a back off timer arranged to prohibit the mobile station from using the at least one gateway for a period of time following a rejected attempt to register with the at least one base station, the rejected attempt being determined by the master controller and identified to the mobile station by the at least one gateway.

Abstract
Improved methods and arrangements are provided for use in mobile communications networks that require re-registration of mobile stations to optimal gateways to support improved call optimization. For example, mobile stations may be required to re-register with gateways that provide more efficient use of terrestrial trunk circuits. When a mobile station is requested to re-register with a more optimal gateway, there is an associated burden on the mobile communications network and supporting signaling system networks. Because of this, there is an inherent potential for intentional or unintentional abuse by one or more subscribers who repeatedly, continually, or simultaneously initiate signaling and/or processing required to optimize the call and re-register the mobile station(s). The present invention prevents such activity by identifying potential abuses, and providing controlling mechanisms within the mobile communications network that monitor and control re-registration and subsequent access requests to the network'"'"'s resources.

8. A mobile communication system comprising:
-
at least one mobile station;
a master controller comprising subscriber information about the mobile station;
a first base station subsystem configured to receive the subscriber information from the master controller when the mobile station registers with the first base station subsystem and to process call requests originated from the mobile station when registered with the first base station subsystem;
a second base station subsystem configured to receive the subscriber information from the master controller when the mobile station registers with the second base station subsystem and to process call requests originated from the mobile station when registered with the second base station subsystem;
a call optimizer at least partially within the first base station subsystem and configured to support processing of call requests from the mobile station based on a called party number in the call request received from the mobile station, the call optimizer being further configured to direct that the mobile station attempt to register with the second base station subsystem as a function of the called party number; and
a back-off timer configured to prohibit the mobile station from using the second base station subsystem for a period of time following a rejected attempt to register with the second base station subsystem, the rejected attempt being determined by the master controller and identified to the mobile station by the second base station subsystem. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for use in a mobile communications network configured to provide call optimization by re-registering a mobile station with a subsequent gateway, the method comprising:
-
determining a failed registration attempt;
identifying to the mobile station by a subsequent gateway of the determined failed registration attempt;
identifying when a mobile station is attempting to register with the subsequent gateway in response to a call optimization determination; and
timing, with a back-off timer, a period of time following the determined failed registration during which the mobile station is prohibited from using the subsequent gateway. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
receiving a called party number from the mobile station through an initial base station;
identifying the subsequent gateway, based on the called party number, wherein the subsequent gateway is configured to process calls through a satellite;
causing the mobile station to attempt to register with the subsequent gateway.

21. The method as recited in claim 16, wherein the step of timing further includes the step of prohibiting the mobile station from using the subsequent gateway for the period of time following the failed registration attempt further comprises, activating a timing mechanism in the mobile station, wherein the timing mechanism is configured to define the period of time.
-
22. The method as recited in claim 21, wherein the step of activating the timing mechanism in the mobile station further comprises using the timing mechanism to measure a pre-defined period of time.
-
23. The method as recited in claim 21, wherein the step of activating the timing mechanism in the mobile station further comprises setting the timing mechanism to measure a programmable-defined period of time.
-
24. The method as recited in claim 16, wherein the step of timing further includes the step of prohibiting the mobile station from using the subsequent gateway for the period of time following the failed registration attempt further comprises:
-
counting a number of failed registration attempts by the mobile station over a first duration of time; and
disallowing the mobile station from registering with the subsequent gateway during a second duration of time if the number of failed registration attempts exceeds a threshold value.
