Method for the location registration of a mobile terminal
First Claim
1. A method for location registration of a mobile terminal via an air interface at a base station of a communication network, comprising the steps of:
- broadcasting via the base station a radio fixed part identity with primary access rights identity as a layer-2 message with a first periodicity and a secondary access rights identity as a layer-2 message with a second periodicity;
comparing at least a predetermined part of the primary access rights identity and, respectively, of the secondary access rights identity in the terminal with at least a part of subscription data stored in the terminal;
registering the terminal at the base station as a home terminal for a positive result of the comparison of a primary access rights identity and registering the terminal at the base station as a visiting terminal for a positive result of the comparison of a secondary access rights identity;
broadcasting, after a change of the primary access rights identity broadcast by the base station, primary access rights identity broadcast by the base station before the change as a secondary access rights identity.

Abstract
A method for the location-dependent registration of a mobile terminal (KE1, KE2) via an air interface at a base station (BS) of a communication network (KN). The base station (BS) broadcasts a radio fixed part identity (RFPI) with primary access rights identity (PARI) as a layer-2-message with a first periodicity and a secondary access rights identity (SARI) as a layer-2 message with a second periodicity. At least a certain part of the primary access rights identity (PARI) and, respectively, of the secondary access rights identity (SARI) is compared in the terminal (KE1, KE2) with at least a part of subscription data (PARK) stored in the terminal. The terminal (KE1, KE2) registers at the base station (BS) as a home terminal in the case of a positive result of the comparison of a primary access rights identity (PARI) and registers at the base station (BS) as a visiting terminal in the case of a positive result of the comparison of a secondary access rights identity (SARI). After a change of the primary access rights identity (PARI) broadcast by the base station (BS), this base station (BS) broadcasts as a secondary access rights identity (SARI) the primary access rights identity (PARI) broadcast by it before the change.
