Method and arrangement for managing a service in a mobile communications system

Abstract

The invention pertains to a method and arrangement for managing a service in a mobile communications system mobile station and an intelligent module in a mobile station. An idea of the invention is that the data needed in the mobile station for a mobile communications service are transferred in encrypted form to several mobile stations at a time. The encryption is based on a key which is transferred individually to mobile stations. Applied to mobile station location this means that the location of a mobile station is determined in the mobile station by means of the timing difference of the signals received from at least two (preferably at least three) base stations and on the basis of the location data of said base stations. The location data are transferred to the mobile station in encrypted form so that they can be utilized only by mobile stations to which the operator has delivered a decryption key needed to decrypt the location data. The decryption key is transferred preferably individually to each mobile station. Decryption may occur in an intelligent module of a mobile station in which case no location data appear in a non-encrypted form outside the intelligent module resulting in data confidentiality. If chargeability is the only requirement decryption and location calculation may also take place elsewhere in the mobile station. The decryption key can be changed in which case the new decryption key is transferred to the mobile station advantageously periodically in conjunction with the location update procedure.

Claim

1. A method for managing a service in a mobile communications system where the same information is transferred to a plurality of mobile stations simultaneously on one and the same transmission channel, characterized in that said information transferred simultaneously to a plurality of mobile stations is encrypted and the encryption is realized using a key such that said key or data needed to construct the current decryption key is transferred separately to a mobile station together with a key or data needed to construct the next decryption key, said transferring occurring in connection with a location update procedure.

2. The method of claim 1, characterized in that said decryption key is transferred individually to the mobile station.

3. The method of claim 1, characterized in that said decryption key is variable.

4. The method of claim 1, characterized in that the decryption of said simultaneously transferred information and decryption key is performed in an intelligent module.

5. A method for locating a mobile station wherein', 'the observed time difference between signals received from at least two base stations is measured in the mobile station,', 'the location information of said at least two base stations are transferred to the mobile station, and', 'the location coordinates of the mobile station are computed in the mobile station on the basis of said time difference and location information of said at least two base stations, characterized in that', 'said base station location information is transferred to the mobile station in encrypted form and the encryption is realized using a key such that said key or data needed to construct a decryption key is transferred separately to each mobile station in connection with a location update procedure.

6. The method of claim 5, characterized in that the calculation for the location of the mobile station is performed in an intelligent module of the mobile station.

7. A mobile communications system in which the same information is transferred to a plurality of mobile stations simultaneously on one and the same transmission channel, characterized in that said mobile communications system comprises means for encrypting, using a key, said information transferred simultaneously to a plurality of mobile stations, and means for transferring the key or data needed to construct a decryption key separately to each mobile station together with a key or data needed to construct the next decryption key, said transferring occurring in connection with a location update procedure.

8. A mobile station location method comprising a mobile communications system which comprises a plurality of base stations and mobile stations such that', 'the observed time difference between signals received from at least two base stations is measured in the mobile station,', 'the location information of said at least two base stations are transferred to the mobile station, and', 'the location coordinates of the mobile station are computed in the mobile station on the basis of said time difference and location information of said at least two base stations, characterized in that', 'arrangements are made for said base station location information to be transferred to the mobile station in encrypted form, a key used in realizing the encryption or data needed to construct a decryption key is arranged to be transferred from the mobile communications system separately to each mobile station in connection with a location update procedure.

9. A mobile station comprising means for receiving on a broadcast channel information related to a service, characterized in that it also comprises means for decrypting said information by means of a decryption key, and means for receiving said decryption key or data needed to construct said decryption key together with a key or data needed to construct the next decryption key on a channel assigned to said mobile station in connection with a location update procedure

10. A mobile station which for the purpose of determining the location of the mobile station comprises', 'means for receiving signals from at least two base stations,', 'means for determining the observed time difference between received signals,', 'means for transferring the location information of said at least two base stations to the mobile station, and', 'means for determining the location of the mobile station on the basis of said time difference and location information of said at least two base stations,', 'characterized in that the mobile station also comprises means for decrypting said base station location information using a decryption key and means for receiving said decryption key or data needed to construct said decryption key on a channel assigned to said mobile station in connection with a location update procedure

11. The mobile station of claim 10, characterized in that it comprises means for sending said mobile station location information to the system

12. An intelligent module of a mobile station, comprising means for receiving from the mobile station encrypted information related to a service, characterized in that it also comprises means for decrypting said information by means of a decryption key and means for receiving said decryption key or data needed to construct said decryption key from the mobile station related to a location update procedure

13. An intelligent module of a mobile station, characterized in that it comprises means for receiving a decryption key or data needed to construct said decryption key from the mobile station together with a key or data needed to construct the next decryption key and means for decrypting base station location information using said decryption key

14. The intelligent module of claim 13, characterized in that it comprises means for receiving said decryption key from the mobile station related to a location update procedure

15. The intelligent module of claim 13, characterized in that it comprises means for calculating the location of the mobile station on the basis of time difference information and base station location information.']
