Abstract

A radio (e.g. a cellular radio telephone) is provided which is capable of operating with a set of incoming and outgoing call functions. Removable memory means 132 are provided (e.g. a smart card) for storing radio function selecting information 133 and a radio user validation code. The radio communicates with a radio communications system in response to the code for enabling the radio to receive incoming calls at least. Radio function control means activate a subset of the call functions within the set of call functions in response to the radio function selecting information stored in the removable memory means.

Claims

1. A radio capable of operating with a set of incoming and outgoing operating functions within a system network having a system network operator, said radio comprising:

removable memory means for storing radio function selecting information and a radio user validation code, said removable memory means having a first set of memory locations that are predefined by the system network operator and a second set of memory locations that are user definable;

memory receiving means for temporarily receiving said removable memory means;

radio function control means coupled to said memory receiving means for enabling said radio for communication with a radio communications system in response to said removable memory means and radio user validation code including at least enabling said radio for receipt of incoming calls; and

said radio function control means are arranged to activate particular operating functions of the radio in response to the radio function selecting information stored in said removable memory means.

2. A radio according to claim 1 further comprising a memory having a plurality of storage locations for storing information including at least telephone numbers, the radio characterized in that said radio function control means disallows access to at least one of said plurality of storage locations.

3. A radio according to claim 2 wherein access includes both read and write access.

4. A radio according to claim 2 wherein access includes write access only.

5. A radio according to claim 2 wherein said radio function control means disallows the radio user write access to a predetermined set of the telephone numbers stored in said memory.

6. A radio according to claim 1 wherein said radio function control means are arranged to activate the radio for receipt of incoming calls and to deactivate all outgoing call functions in response to the radio function selecting information stored in said removable memory means.

7. A radio according to claim 1 further comprising a keypad having a plurality of numerical keys and a plurality of feature keys wherein said radio function control means allows the use of a subset only of said plurality of feature keys in dependence on said radio function selecting information.

8. A radio according to claim 7 wherein one of said plurality of feature keys is an encryption selector key.

9. A radio according to claim 7 wherein one of said plurality of keys is a memory selector key.

10. A radio according to claim 1 wherein said radio function control means disallows the radio user from initiating international calls in dependence on said radio function selecting information.

11. A radio according to claim 8 wherein said radio function control means also disallows the radio user from initiating trunk calls in dependence on said radio function selecting information.

12. A radio according to claim 1, wherein said radio function control means disallows use of peripheral equipment.

13. A radio according to claim 1 in combination with a first removable memory means and a second removable memory means, wherein said first removable memory means stores first radio function selecting information for activating a first subset of said set of functions and said second removable memory means stores second radio function selecting information for activating a second different subset of said set of functions.

14. A radio according to claim 1 comprising:

output indicating means for providing user-discernable output indications, wherein said radio function control means are arranged to control said output indication means in response to the radio function selecting information stored in said removable memory means.

15. A radio according to claim 14, wherein said output indication means comprises a display, wherein a memory is provided for storing information for display in a plurality of languages, and wherein said radio function control means are arranged to select a language for display in accordance with the radio function control information.

16. A radio according to claim 14, wherein said output indication means comprises a display arranged to display selectable functions and wherein the set of selectable function which is displayed, out of the set of all the available selectable function, is controlled by the radio function control means in accordance with the radio function selecting information.

17. A radio according to claim 16, wherein the radio function selecting information is resetable by the user through a keypad on the radio.

18. A radio according to claim 14, further comprising means for receiving and displaying messages directed to the radio as well as to a plurality of other radios, means for identifying that the message is not specific to the radio and means for selectively preventing display of the message in accordance with the radio function selecting information.

19. A radio according to claim 14, comprising audible output means and volume control means for selection of the volume thereof in response to the radio function selecting information.

20. A radio according to claim 19, wherein the radio function selecting information is resetable by the user through a keypad on the radio.

21. A radio capable of operating within a set of incoming and outgoing call functions, said radio comprising:

removable memory means for storing radio functions selecting information that includes a first set of memory locations that are defined by a network system operator and a second set of memory locations that are user definable and a radio user validation code;

memory receiving means for temporarily receiving said removable memory means;

radio function control means coupled to said memory receiving means for enabling said radio for communication with a radio communications system in response to said removable memory means and radio user validation code including at least enabling said radio for receipt of incoming calls;

a memory having a plurality of storage locations for storing information including at least telephone numbers; and

said radio function control means are arranged to activate a subset of said call functions within said set of call functions in response to the radio function selecting information stored in said removable memory means and in that said radio function control means disallows the radio user write access to a predetermined set of the telephone numbers stored in said memory.

22. A radio capable of operating within a set of incoming and outgoing call functions, said radio comprising:

removable memory means for storing radio functions selecting information that includes a first set of memory locations that are defined by a network system operator and a second set of memory locations that are user definable and a radio user validation code;

memory receiving means for temporarily receiving said removable memory means;

radio function control means coupled to said memory receiving means for enabling said radio for communication with a radio communications system in response to said removable memory means and radio user validation code including at least enabling said radio for receipt of incoming calls;

a memory having a plurality of storage locations for storing information including at least telephone numbers; and

said radio function control means are arranged to activate the radio for receipt of incoming calls and to deactivate all outgoing call functions in response to the radio function selecting information stored in said removable memory means.
