Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular radio telephone, and more particularly to a programming device and a programming method for programming data into a mobile radio telephone.

[0002]

Prior to the first use of cellular radiotelephones,
Functional data (also known as setup or installation data) must first be programmed into the phone. Such data is, for example,
Subscriber's number, coverage area and / or system within which the mobile phone will be used, retailer and / or installer code, and setup data and similar required for use of the mobile phone The date when the data was embedded.

Setup data has traditionally been incorporated into the phone by the retailer at the time of delivery. This is done, for example, using a personal computer programmed for this purpose, through which the setup
Data may be electronically erasable PROM in a telephone, for example
It is input to a programmable read-only memory (PROM) such as (EEPROM).

The above method is uneconomical and complicated, requires additional equipment, and requires the retailer to have the ability to perform its job. Also, after this is done, the cellular telephone network operator will be asked to operate everything programmed into the telephone, which is a time consuming task.

Telephone programming may take place at the factory. This has the disadvantage that the retailer must be able to predict sales in order to have a sufficient number of programmed phones available. In addition, the operator of the cellular telephone network must be commissioned to operate the sold telephone. If the factory has to make changes to the data already programmed, then another programming or service device must be used at the delivery location so that the retailer can make the changes.

The shortcomings of conventional programming methods become more prominent as mobile phones become more and more commonly used and sold in consumer goods stores rather than specialty stores. The present invention has been made in view of the above problems, and an object of the present invention is to provide a programming system and a programming method capable of setting up setup data in a cell-type wireless telephone with a small number of programming devices.

Telephone 10 includes a radio frequency transceiver 13 and all other features traditionally found in cell phones. These aspects are not directly related to the invention and will not be described further herein, but are used by the microprocessor 18 to control all basic telephone functions and keypad and display functions. I will mention that it will be.

Microprocessor 18 is connected to PROM 17, which is preferably an EEPROM,
The PROM 17 stores setup data, software, and index numbers for useful telephone numbers, for example. The software needed to program the setup data is stored in PROM 17. Phone 10
Includes an earphone 11 and a microphone 12 for inputting and outputting voice, as is conventionally done in all telephones. The earphone 11 and the microphone 12 are connected via switches 15 and 16 to a radio frequency (RF) transceiver 13 of the telephone 10 during normal operation, and dual tone multi-frequency when programming setup data into the EEPROM 17. (Dual
-Tone multi-frequency (DTMF) signal encoder / decoder (hereinafter referred to as DTMF codec) 14
Connected to.

The DTMF codec 14 encodes and decodes the DTMF signals transmitted and received through the microphone 17 and the earphone 11, respectively. A programming device 40 with acoustic rejection characteristics, for example a computer terminal located in a central office, comprises software for loading setup data into the telephone 10 and is coupled to the terminal device 20 via a link 30. DT is done
It includes means for transmitting and receiving MF data signals.

The terminal device 20 is a known device that converts an acoustic signal into a form that can be transmitted via the link 30 such as an acoustic coupler. In the simplest embodiment, a suitable cable can be used as the link 30, but in view of the present invention, a general network such as an optional telephone network, cellular telephone network, or the like is used. It is advantageous to use it as the link 30.

The terminal device 20 is located at a place, such as a retail store, where the setup data should be loaded into the telephone.
