Method for controlling an accessory of a subscriber terminal equipment and an accessory of a subscriber terminal equipment
First Claim
1. A method for controlling an accessory of a location data maintaining subscriber terminal equipment of a cellular network, said cellular network comprises one or more base stations in each cell, and said accessory comprises a specified subscriber identifier differing from the identifier of the subscriber terminal equipment within the network, the method comprising the steps of:
- connecting the accessory to the subscriber terminal equipment when the accessory is activated for location determination,the combination of the terminal equipment and the accessory determining its location by communicating with one or more base stations and storing the location data into a memory register,whenever a call is being established when the subscriber terminal equipment is connected to the accessory, said combination checking its location by communicating with one or more base stations,comparing its location at that moment with the location in the memory register, and in case the locations differ from one another more than a preset threshold value,obstructing the use of the subscriber identifier of the accessory during the call, and enabling use of the subscriber identifier of the terminal equipment.

Abstract
The present invention relates to a method for controlling an accessory of a location data maintaining subscriber terminal equipment (204) of a cellular network and an accessory (214), and which comprises memory (202, 210) for maintaining a specified subscriber identifier differing from the identifier of the subscriber terminal equipment, and circuitry (206) for connecting to the terminal equipment. In order to enable reliable checking of location data, the combination of the terminal equipment and the accessory comprises processor circuitry (200, 204, 210) for determining its location in connection with activation, memory (210) for storing location parameters, processor with memory circuit (200, 210) for checking its location whenever a call is established when the terminal equipment is connected to the accessory, wherein the processor compares the checked location with the stored location data, and obstructs the use of the subscriber identifier during the call in case the location data differ from one another more than the preset threshold value.

9. A method for controlling an accessory of a location maintaining data subscriber terminal equipment of a cellular network, said cellular network comprises one or more base stations in each cell, and said accessory comprises a specified subscriber identifier differing from the identifier of the subscriber terminal equipment within the network, the method comprising the steps of:
-
connecting the accessory to the subscriber terminal equipment when the accessory is activated for location determination, the combination of the terminal equipment and the accessory determining its location by communicating with one or more base stations and storing the location data into a memory register, whenever a call is being established when the subscriber terminal equipment is connected to the accessory, said combination checking its location by communicating with one or more base stations, comparing its location at that moment with the location in the memory register, and in case the locations differ from one another more than a preset threshold value, obstructing the use of the subscriber identifier of the accessory during the calls subsequent to the established call, and enabling use of the subscriber identifier of the terminal equipment.

10. A method for controlling an accessory of a location data maintaining subscriber terminal equipment of a cellular network, said cellular network comprises one or more base stations in each cell, and said accessory comprises a specified subscriber identifier differing from the identifier of the subscriber terminal equipment, the method comprising the steps of:
-
connecting the accessory to the subscriber terminal equipment when the accessory is activated for location determination, the combination of the terminal equipment and the accessory determining its location by communicating with one or more base stations and storing the location data into a memory register, emptying the memory register, into which the data on the location of the accessory is stored, on the basis of controlling from the cellular network.

11. An accessory of a subscriber terminal equipment of a cellular network, said cellular network comprises one or more base stations in each cell, and said accessory comprises means for maintaining a specified subscriber identifier differing from the identifier of the subscriber terminal equipment, and means for connecting to the terminal equipment, wherein the combination of the terminal equipment and the accessory further comprises:
-
means for determining its location upon activation of said accessory, means for storing location parameters, means for checking its location whenever a call is established when the terminal equipment is connected to the accessory, means for comparing the checked location with the stored location data, and means for obstructing the use of the subscriber identifier during the call in case the location data differ from one another more than the preset threshold value, and means for enabling use of the subscriber identifier of the terminal equipment. - View Dependent Claims (12, 13, 14, 15, 16)
