Abstract

Radio telecommunication apparatus which includes storing a plurality of identification numbers of the apparatus. Each identification number of the apparatus is stored with an associated system identification number. Responsive to a system identification number transmitted from a base unit an identification number of the apparatus corresponding to the system identification number is selected. The selected identification number is broadcast over a radio channel. Still the apparatus receives all incoming calls having an identification number which is the same as one of the stored identification numbers.

7. The apparatus of claim 1 further comprising input means for inputting a confirmation request to said transmitting means and display means responsive to said transmitting means and said input means for displaying said transmitted identification number of the apparatus.

8. The apparatus of claim 1 further comprising input means for inputting a confirmation request to said transmitting means and voice synthesis means responsive to said transmitting means and said input means for generating a synthesized voice corresponding to said transmitted identification number of the apparatus.

9. Cellular telecommunication apparatus comprising:

receiving means for receiving signals including a system identification number, the signals being broadcast over one or more radio channels;

storing means for storing a plurality of identification numbers for said apparatus and a plurality of system identification numbers, each of said identification nubmers for said apparatus corresponding to one of said system identification numbers;

comparing means coupled to said receiving means and said storing means for comparing the received system identification number with each of the system identification number stored in said storing means; and

transmitting means responsive to said comparing means for transmitting an identification number of the apparatus corresponding to a system identification number stored in said storing means which is identical to the received system identification number.

10. Radio telecommunication apparatus for use in a radio telecommunication system, wherein said radio telecommunication system encompasses a plurality of areas each having one or more base units which broadcast a system identification number over one or more radio channels within the area of said base units, said radio telecommunication apparatus comprising:

input means for inputting a call origination request and address information of a radio telecommunication apparatus to be called;

receiving means responsive to said input means for receiving the system identification number;

storing means for storing a plurality of identification number of the apparatus and a plurality of system identification numbers, each of the identificatin numbers of the apparatus corresponding to one of the system identification numbers;

comparing means, coupled to said receiving means and said storing means, for comparing the received system identification number with each of the stored system identification numbers; and

transmitting means coupled to said comparing means for transmitting a stored identification number of the apparatus, corresponding to a stored system identification number which is identical to the received system identification number, with the input address information to the base staion in response to the call origination request.

11. The apparatus of claim 10 wherein said transmitting means further transmits a predetermined identification number of the apparatus in the event that the received system identification number is not identical to any one of said stored system identification numbers.

12. The apparatus of claim 10 wherein said transmitting means further transmits an identification number for the apparatus corresponding to a stored system identification number which has a predetermined relationship with the received system identification number in the event that the received system identification number is not identical to any one of said stored system identification numbers.

13. The apparatus of claim 10 further comprising display means responsive to said transmitting means for displaying said transmitted identification number of the apparatus.

14. The apparatus of claims 11 or 12 further comprising alarming means responsive to said input means and said comparing means for alarming a user of the appartus when the received system identification number is not identical to any one of the stored system identification numbers.

15. The apparatus of claim 14 wherein said alarming means comprises voice synthesis means for synthesizing a predetermined voice.

16. Radio telecommunication apparatus comprising:

receiving means for receiving signals including one or more mobile identification numbers, the signals being broadcast over one or more radio channels;

storing means for storing a plurality of identificatin numbers of the apparatus;

comparing means coupled to said receiving means and said storing means for comparing the received mobile identification numbers with said identification numbers of the apparatus stored in said storing means; and

transmitting means responsive to said comparing means, in the event that one of the received mobile identification numbers is identical to one of the stored identification numbers of the apparatus, for transmitting a response signal including the identical mobile identification number over a radio channel.

17. A method of registering a location of a mobile unit for use in a radio telecommunication system, wherein said radio telecommunication system encompasses a plurality of areas each having one or more base units which broadcast a system identification number over one or more radio channels within the area of said base units, the method comprising the steps of:

storing a plurality of identification numbers of the mobile unit and a plurality of system identification numbers, each of the identification numbers of the mobile unit corresponding to one of the system identification numbers;

receiving a system identification number broadcast from a base station;

comparing the received system identification number with the stored system identification nubmers; and

transmitting a stored identification number of the mobile unit, corresponding to a stored system identification number which is identical to the received system identification number, to the base station.

18. The method of claim 17 wherein the step of transmitting further comprises the step of transmitting a predetermined identification number of the mobile unit in the event that the received system identification number is not identical to any one of the stored system identification numsers.
