Radio telephone system and method of registering an ID code therein
First Claim
1. A radio telecommunication system, comprising:
- a first radio unit having an identification code;
a second radio unit;
generating means, provided in one of the first and second radio units, for generating a first reference code;
establishing means for establishing a radio link between the first radio unit and the second radio unit;
comparing means provided in the other one of the first and second radio units for comparing said first reference code generated by said one of the first and second radio units with a second reference code previously stored in said other one of the first and second radio units;
transmitting means for transmitting the identification code stored in the first radio unit to the second radio unit over the established radio link; and
storing means provided in the second radio unit for storing the identification code transmitted from the first radio unit in response to a match of the compared first and second reference codes.

Abstract
A radio telephone system which comprises a base unit (1) connected to a wire line (3) and at least one radio telephone set (2) to be coupled with the base unit (1) through a radio circuit, and in which coupling between the base unit and the radio telephone set is controlled on the basis of an identification code. A non-volatile first memory (58) having an identification previously written therein is provided in one of the base unit (1) and the radio telephone set (2), and an optionally writable second memory (60) is provided in the other. Written in the second memory (60) is a predetermined identification code on the basis of the identification code stored in the first memory (58).

1. A radio telecommunication system, comprising:
-
a first radio unit having an identification code; a second radio unit; generating means, provided in one of the first and second radio units, for generating a first reference code; establishing means for establishing a radio link between the first radio unit and the second radio unit; comparing means provided in the other one of the first and second radio units for comparing said first reference code generated by said one of the first and second radio units with a second reference code previously stored in said other one of the first and second radio units; transmitting means for transmitting the identification code stored in the first radio unit to the second radio unit over the established radio link; and storing means provided in the second radio unit for storing the identification code transmitted from the first radio unit in response to a match of the compared first and second reference codes. - View Dependent Claims (2, 3)

4. A method of registering an identification code stored in a first radio unit into a second radio unit, comprising the steps of:
-
generating a first reference code at one of the first and second radio units; establishing a radio link between the first radio unit and the second radio unit; transmitting the first reference code from said one of the first and second radio units to the other one of the first and second radio units over the established radio link; comparing said first reference code with a second reference code previously stored in said other one of the first and second radio units; transmitting the identification code stored in the first radio unit to the second radio unit over the established radio link; and storing the identification code transmitted from the first radio unit into the second radio unit in response to a match of the compared first and second reference codes. - View Dependent Claims (5, 6, 7)

8. A radio telephone system, comprising:
-
a base unit connected to a telephone line; a radio telephone set comprising means for coupling said radio telephone set through a radio link to said base unit; means for electrically connecting said base unit to said radio telephone set; first memory means disposed in said base unit to be optionally written therein; second nonvolatile memory means disposed in said radio telephone set and having an identification code previously written therein which is not previously stored within said base unit; means for writing in said first memory means said identification code previously written in said second memory means, through said radio link; means for inputting an input secret number; means for comparing said input secret number with a preset secret number and for producing a coincidence output when said input secret number and said preset secret number coincide; and means for enabling operation of said writing means only when said comparing means produces a coincidence output. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
