Abstract

Claims (47)

1. A method for controlling a mobile subscriber's local operation in a mobile communication system, in which a mobile station is arranged to roam within a cellular network and to connect to a cell, the method comprises the steps of:

defining a set of local parameters for the mobile subscriber;

using the set of local parameters to define a localized service area related to special services that are available to the mobile subscriber;

defining local parameters of the cell wherein the local parameters of the cell are used to define services that are available in the cell;

providing the set of local parameters for the mobile subscriber and the local parameters of the cell to a unit controlling operation of the mobile station, the control unit receiving the same set of local parameters of the mobile subscriber regardless of a current location of the mobile station;

comparing the set of local parameters for the mobile subscriber with the local parameters of the cell; and

allowing a set of local service for the mobile subscribe on the basis of compatibility of said local parameters; and

disallowing another set of service for the mobile subscriber on the basis of compatibility of the local parameters,

wherein the special services cover at least one of special tariff in the localized service area or special access rights.

2. A method as claimed in claim 1 , wherein set-up of calls originating from or terminating to the subscriber's mobile station is barred in those cells in which the selected set of local parameters for the mobile subscriber is not compatible with the local parameter of the cell.

3. A method as claimed in claim 1 , wherein the mobile station is barred from connecting to those cells in which the selected set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible.

4. A method as claimed in claim 2 , wherein the set of local parameters for the mobile subscriber and the local parameter of the cell are interpreted as compatible if the parameters are the same.

5. A method as claimed in claim 2 , further comprising:

checking in response to the fact that the set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible whether there is any other mobile-subscriber-related access code allowing call set-up; and

allowing call set-up in response to the fact that there is a mobile-subscriber-related access code allowing call set-up.

6. A mobile communication system controlling a mobile subscriber's local operation, in which a mobile station is arranged to roam within a cellular network and to connect to a local cell, the system comprising:

a subscriber data base for storing a set of local parameters for the mobile subscriber wherein the set of local parameters for the mobile subscriber are used to define a localized service area related to special services—that are available to the mobile subscriber;

a data base for storing local parameters of the cell wherein the local parameters of the cell are used to define services that are available in the cell;

means for providing set of local parameters for the mobile subscriber and the local parameters of the cell to a unit controlling operation of the mobile station, the set of mobile subscriber's local parameters being the same set of local parameters of the mobile subscriber regardless of a current location of the mobile station;

means for comparing the set of local parameters for the mobile subscriber with the local parameters of the cell;

means for allowing a set of local services of the mobile subscriber on the basis of compatibility of said local parameters; and

means for disallowing another set of services for the mobile subscriber on the basis of compatibility of the local parameters,

wherein the special services cover at least one of special tariff in the localized service area or special access rights.

7. A system as claimed in claim 6 , wherein said means are arranged to bar set-up of calls originating from or terminating to the subscriber's mobile station in those cells in which the selected set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible.

8. A system as claimed in claim 6 , wherein said means are arranged to bar the subscriber from connecting to those cells in which the selected set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible.

9. A system as claimed in claim 7 , wherein the set of local parameters for the mobile subscriber and the local parameter of the cell are interpreted as compatible if the parameters are the same.

10. A system as claimed in claim 7 , wherein the unit controlling local operation of the mobile station is arranged to:

check in response to the fact that the set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible whether there is any other mobile-subscriber-related access code allowing call set-up; and

allow call set-up in response to the fact that there is a mobile-subscriber-related access code allowing call set-up.

11. A subscriber data base in a mobile communication system controlling a mobile subscriber's local operation, in which a mobile station is arranged to roam within a cellular network and to connect to a selected local cell the subscriber data base is arranged to:

store a set of local parameters for the mobile subscriber, wherein the set of local parameters for the mobile subscriber are used to define a localized service area related to special services that are available to the mobile subscriber; and

transfer said set of local parameters for the mobile subscriber to a unit controlling operation of the mobile station or to a subscriber data base in connection with the unit, the set of mobile subscriber's local parameters being the same set of local parameters of the mobile subscriber regardless of a current location of the mobile station,

wherein the special services cover at least one of special tariff in the localized service area or special access rights.

12. A subscriber data base as claimed in claim 11 , wherein the subscriber data base is arranged to transfer said set of local parameters for the mobile subscriber to the subscriber data base in connection with the unit controlling operation of the mobile station in connection with location updating.

13. A unit controlling a mobile subscriber's local operation in a mobile communication system, in which a mobile station is arranged to roam within a cellular network and to connect to a selected local cell comprising:

means for receiving a set of local parameters for the mobile subscriber and local parameters of the cell wherein the set of local parameters for the mobile subscriber are used to define a localized service area related to special services that are available to the mobile subscriber and the local parameters of the cell are used to define services that are available in the cell, the set of mobile subscriber's local parameters being the same set of local parameters of the mobile subscriber regardless of a current location of the mobile station;

means for comparing the set of local parameters for the mobile subscriber with the local parameters of the cell;

means for allowing a set of local services for the mobile subscriber on the basis of compatibility of said local parameters; and

means for disallowing another set of services for the mobile subscriber on the basis of compatibility of said local parameters,

wherein the special services cover at least one of special tariff in the localized service area or special access rights.

14. A unit as claimed in claim 13 , wherein the unit is arranged to bar set-up of calls originating from or terminating to the subscriber's mobile station in those cells in which the set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible.

15. A unit as claimed in claim 13 , wherein the unit is arranged to bar the mobile station from connecting to those cells in which the selected set of local parameters for the mobile subscriber and the local parameter of the cell are incompatible.

16. A unit as claimed in claim 14 , wherein the unit is arranged to interpret the selected set of local parameters for the mobile subscriber and the local parameter of the cell as compatible if the parameters are the same.

17. A unit as claimed in claim 14 , wherein the unit is arranged to:
