Checking the access right of a subscriber equipment
First Claim
1. A method for checking the access right of a subscriber equipment in a mobile telephone system comprising a network infrastructure and a plurality of mobile equipment, each said mobile equipment being a combination of a subscriber equipment provided with an equipment identity and an individual subscriber identification module that is detachably connected to said subscriber equipment, whereupon a mobile equipment can be formed by attaching said subscriber identification module to any subscriber equipment, said method comprising:
- before said subscriber identification module is detached from said subscriber equipment, storing said equipment identity of said subscriber equipment in said subscriber identification module;
after said subscriber identification module has been connected to any said subscriber equipment, comparing said equipment identity stored in said subscriber identification module to said equipment identity stored in said subscriber equipment of the combination; and
when said equipment identities are identical, selecting a first alternative for checking the access right; and
when said equipment identities are different, selecting a second alternative for checking the access right.

Abstract
A method for checking the access right of a subscriber equipment, whereupon a mobile equipment can be formed by attaching the subscriber identification module to any subscriber equipment. Before the subscriber identification module is detached from the subscriber equipment, the equipment identity of this subscriber equipment is stored in the subscriber identification module. After the subscriber identification module has been connected to the subscriber equipment, the equipment identity stored in the subscriber identification module is compared in the mobile equipment formed with the equipment identity of the subscriber equipment of the combination. When the equipment identities are identical, a first alternative for checking the access right is selected, and when the equipment identities are different, a second alternative for checking the access right is selected.

2. A method for checking the access right of a subscriber equipment in a mobile telephone system comprising a network infrastructure and a plurality of mobile equipment, each said mobile equipment being a combination of a subscriber equipment and a subscriber identification module that is provided with a subscriber identity and that is detachably connected to said subscriber equipment, whereupon a mobile equipment can be formed by attaching said subscriber identification module to any subscriber equipment, said method comprising:
-
before said subscriber identification module is detached from said subscriber equipment, storing said subscriber identity contained in said subscriber identification module in said subscriber equipment; after said subscriber identification module has been attached to said subscriber equipment, comparing any said subscriber identity stored in said subscriber identification module to said subscriber identity stored in said subscriber equipment of the combination; and when said subscriber identities are identical, selecting a first alternative for checking the access right, whereupon registration of said mobile equipment onto said network infrastructure is continued, and when said subscriber identities are different, selecting a second alternative for checking the access right, whereupon the access right of said subscriber equipment is checked by said network infrastructure. - View Dependent Claims (6, 7)

10. The method for checking the access right of a subscriber equipment in a mobile telephone system comprising a network infrastructure and a plurality of mobile equipment, each said mobile equipment being a combination of a subscriber equipment provided with an equipment identity and an individual subscriber identification module that is detachably connected to said subscriber equipment, whereupon a mobile equipment can be formed by attaching said subscriber identification module to any subscriber equipment, said method comprising:
-
a) comparing in said mobile equipment said subscriber equipment identity stored in said subscriber identification module with said equipment identity of said subscriber equipment of the combination; based on said comparison, b) continuing registration of said mobile equipment onto said network infrastructure, if said subscriber identification module contains said subscriber equipment identity, or c) checking the access right of said subscriber equipment by said network infrastructure, if said subscriber identification module does not contain said subscriber identity of said subscriber equipment; and as a result of said checking of access right of said subscriber equipment, d) storing said subscriber identity of said subscriber equipment in said subscriber identification module and continuing registration of said mobile equipment onto said network infrastructure if said subscriber equipment has access right to said network infrastructure. - View Dependent Claims (12, 13, 14)

11. A method for checking the access right of a subscriber equipment in a mobile telephone system comprising a network infrastructure and a plurality of mobile equipment, each said mobile equipment being a combination of a subscriber equipment and a subscriber identification module that is provided with a subscriber identity and that is detachably connected to said subscriber equipment, whereupon a mobile equipment can be formed by attaching said subscriber identification module to any subscriber equipment, said method comprising:
-
a) comparing in said mobile equipment, said subscriber identity stored in said subscriber identification module with said subscriber identity stored in said subscriber equipment of the combination; b) continuing based on said comparison, registration of said mobile equipment onto the network infrastructure, if said subscriber identity stored in said subscriber equipment of said combination is identical to said subscriber identity stored in said subscriber identification module, or c) checking the access right of said subscriber equipment by said network infrastructure, if said subscriber identity stored in said subscriber equipment of said combination is not identical to said subscriber identity stored in said subscriber identification module; and d) storing said subscriber identity in said subscriber equipment and continuing registration of said mobile equipment onto said network infrastructure, if said subscriber equipment has the access right to said network infrastructure according to said checking of the access right of the subscriber equipment. - View Dependent Claims (15, 16)
