Method for performing RR-level registration in a wireless communication system
First Claim
1. A method for registering with a plurality of registration zones in a wireless communication network, the method comprising:
- receiving an assignment for a first Temporary Mobile Station Identity (TMSI) from a first network entity in response to registration with a first registration zone;
registering with a second network entity in a second registration zone;
receiving an assignment for a second TMSI from the second network entity in response to registration with the second registration zone;
maintaining a first counter to provide an indication to initiate timer-based registration;
initiating timer-based registration if a value in the first counter exceeds a timer-based registration count value;
receiving a value representative of a maximum expiration period for timer-based registration; and
setting the timer-based registration count value based on the received value.

Abstract
Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at RR-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

19. A method for registering with a plurality of Radio Temporary Mobile Station Identity (R-TMSI) zones in a wireless communication network, the method comprising:
-
registering with a first base station in a first R-TMSI zone; receiving an assignment for a first R-TMSI code from the first base station in response to registration with the first R-TMSI zone; registering with a second base station in a second R-TMSI zone; receiving an assignment for a second R-TMSI code from the second base station in response to registration with the second R-TMSI zone; activating a first timer for the first R-TMSI zone upon registration with the second base station; and deactivating a second timer for the second R-TMSI zone upon registration with the second base station. - View Dependent Claims (20)

21. A method for managing multiple Temporary Mobile Station Identities (TMSIs) in a radio communication network, the method comprising:
-
assigning a first TMSI to a mobile station via a first base station when the mobile station enters a first Radio TMSI (R-TMSI) zone; registering the mobile station with a second base station in a second R-TMSI zone; assigning a second TMSI to the mobile station via the second base station so that the mobile station is registered in a plurality of R-TMSI zone, activating a first timer for the first R-TMSI zone upon registration with the second base station; and deactivating a second timer for the second R-TMSI zone upon registration with the second base station.

22. An apparatus for registering with a plurality of registration zones in a wireless communication network, comprising:
-
means for receiving an assignment for a first Temporary Mobile Station Identity (TMSI) from a first network entity in response to registration with a first registration zone; means for registering with a second network entity in a second registration zone; means for receiving an assignment for a second TMSI from the second network entity in response to registration with the second registration zone, means for maintaining a first counter to provide an indication to initiate timer-based registration; and means for initiating timer-based registration if a value in the first counter exceeds a timer-based registration count value; means for receiving a value representative of a maximum expiration period for timer-based registration; and means for setting the timer-based registration count value based on the received value. - View Dependent Claims (23, 24)
