Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a cellular radio telephone device which requires a registration process with an RJ11 interface.

[0002]

2. Description of the Related Art In a general cellular radio telephone system, there are a plurality of base stations and registration processing (Registratio
The base station to communicate with is selected by n). This registration process is the first communication with the base station, and if this process is not performed, neither transmission to the base station nor reception from the base station is possible. In the registration process, when the power of the mobile station is turned on, a registration message including the mobile station's telephone number, manufacturing number, etc. is automatically transmitted to the base station. This registration message enables the base station to communicate with the mobile station.

When an RJ11 interface (for example, the interface disclosed in Japanese Examined Patent Publication No. 4-16982) is added to this mobile station, a terminal using a two-line signal of a telephone line as an input / output signal, such as an additional telephone or A FAX or personal computer communication device can be connected and used. The telephone number of this terminal may be the same as the telephone number of the mobile station body, or may be a different telephone number.

[0004]

When the telephone number of the terminal is different from the telephone number of the mobile station body,
After performing the registration process for the mobile station main phone number, the registration process is automatically performed for the terminal phone number. Since the mobile station performs registration processing based on the telephone number of the terminal written in the storage unit, the mobile station will register the terminal with the base station even when the terminal is not connected to the RJ11 interface. For this reason, the base station has a drawback that it performs a calling operation and occupies a channel even when there is an incoming call to that number.

[0005]

The present invention has been made in view of the above points, and a first feature thereof is a connection detecting unit for detecting whether or not a terminal is connected to the RJ11 interface, and the connection detecting unit. It is provided with a control unit that performs the registration process of the terminal based on the output of the detection unit. A second feature is that a signal detection unit that detects a signal from the terminal is provided, and the control unit performs the registration processing of the terminal based on the output of the signal detection unit. A third feature is that a registration key is provided, and the control unit performs the registration process of the terminal based on the operation of the registration key.

[0006]

Function: The registration operation is performed only when the connection of the terminal is detected, and the registration operation is not performed when the connection is not established. Alternatively, registration processing is performed when a signal from the terminal is detected.
Alternatively, when the registration key is pressed, the registration operation is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a cellular radio telephone device (1) of the present invention.
FIG. 3 is a block diagram showing a state in which an external telephone (2) is connected to. (2) is a general modular type telephone that is connected to a telephone line by a modular jack. The telephone (2) may be replaced with a terminal such as a FAX or a personal computer communication device.

(3) is the RJ11 interface,
It is an interface that enables a touch tone or pulse dial type telephone adapted to two-line signals of a telephone line to be adapted to a cellular type wireless telephone device (transceiver). The RJ11 interface (3)
Comprises a 2-line to 4-line converter (4), a DTMF receiver (5) and a hook detector (6). The 2-wire to 4-wire conversion unit (4) is a 2-wire signal to be input to and output from the telephone (2) and a 4-wire inside the main body.
Converts line signals. The DTMF receiver (5) outputs the DTMF signal (phone number of the other party) output from the telephone (2).
Is detected as a signal compatible with the cellular system. The hook detector (6) detects whether the telephone (2) has been off-hook. (7) is the RJ11 interface (3)
It is a connection detection unit that detects whether or not the telephone (2) is connected to. The detection method includes, for example, a method in which a mechanical switch is provided at the terminal portion of the modular jack for detection, or a method in which a dedicated telephone having a modular jack to which a line for detecting connection is added is used for detection. (8) is a handset for the main body. (9) is a switch for switching between connecting the communication signal line with the control unit (10) to the handset (8) or the telephone set (2).

The control unit (10) controls each unit based on the program stored in the storage unit (11). Memory (1
1) is composed of a ROM, a RAM, etc., and stores at least the above-mentioned program and information relating to the registration processing to the base station. The contents are ESN (Equipment Serial No.), MI
N (Mobile Identity No.) and the like. The ESN is 32-bit data and is a device identification number assigned to each device at the factory. MIN is 34-bit data, and consists of 3-digit MIN2 (for example, city code) and 7-digit MI.
Indicates the telephone number of N1 (for example, the local area code). Two types of MIN, a main body and a telephone, are attached by a dealer. (1
Reference numeral 2) is an operation unit, which has at least a ten-key pad (13) for inputting a telephone number. (14) is a display unit that displays a telephone number, time, and the like.

Reference numeral (15) is a transmission section, which is a control section (10).
The RF signal is RF-encoded and transmitted from the base station via the duplexer (16) and the antenna (17). Reference numeral (18) is a receiver, which receives an RF signal from the base station through an antenna (1
7) and the duplexer (16) to convert the signal into a baseband signal and output it to the control unit (10). The duplexer (16) enables the antenna (17) to be used for both reception and transmission.

A call originating from the telephone set (2) after the registration process (described later) with the base station will be described. When the handset (not shown) of the telephone (2) is raised, the hook detection unit (6)
Detects that it is off-hook. As a result, the control unit (10) waits for a DTMF signal (telephone number input) from the telephone (2). When the telephone number is entered, D
The TMF signal is detected by the DTMF receiver (5), whereby the control unit (10) sends a calling signal to the base station via the transmission unit (15), the duplexer (16) and the antenna (17). When there is a response from the called party and a call is made, in the case of receiving a call, the RF signal from the base station is converted into a baseband signal through the antenna (17), the duplexer (16) and the receiving unit (18). Then, the control unit (10) demodulates the data signal into an audio signal, and the two-wire to four-wire conversion unit (4)
To output a voice signal to the telephone set (2). When sending a call, the voice signal input from the telephone (2)
The line (4) is passed through the line conversion unit (4), encoded by the control unit (10), converted into an RF signal by the transmission unit (15), and the duplexer (1
6), transmit to the base station through the antenna (17).

Prior to the above-mentioned calling operation, the base station must be registered. The present invention relates to this registration process, which will be described. When the power of the main body is turned on, the control unit (10) reads out registration information such as ESN, MIN, etc. regarding the main body from the storage device (11). The channel having the strongest communication channel is searched, a registration message based on the registration information is sent to the base station, and the registration process of the main body is completed. Conventionally, the same registration process was performed on the telephone set (2) immediately after completing the registration process of the main body. In the case of the first embodiment, when the registration process of the main body is completed, the control unit (10) checks whether or not the telephone set (2) is connected based on the input from the connection detection unit (7). If it is connected, the registration processing of the telephone (2) is performed similarly to the main body, and if it is not connected, the registration processing of the telephone (2) is not performed. The registration process is performed not only when the power of the main body is turned on, but also periodically.

A second embodiment will be described with reference to the drawings. Second
In the embodiment, the telephone (2) is output by the telephone (2).
The connection is recognized. FIG. 2 is a block diagram of the second embodiment. In FIG. 2, the connection detection unit (7) of FIG. 1 is replaced with a signal detection unit (19). The signal detection unit (19) detects that the telephone (2) connected to the RJ11 interface (3) has been operated and outputs this signal to the control unit (10).

The registration processing of the second embodiment will be described. In the main body registration process, the power is turned on as in the first embodiment.
If set to, it will be done automatically. The registration process of the telephone (2) is not performed at this time, but is performed after the control unit (10) confirms the signal of the telephone (2) by the signal detection unit (19). For the sake of explanation, the signal detection unit (19) is RJ11.
Although the configuration is different from the interface (3), RJ1
The cost can be reduced by sharing one interface (3). As an example, a case where the hook detector (6) is used as the signal detector (19) will be described. The user connects the telephone (2) to the RJ11 interface (3), turns on the power of the main body, and then carries a handset (not shown) of the telephone (2) for a call test. As a result, the hook detector (6) detects off-hook,
As a result, the control unit (10) recognizes that the telephone (2) is connected, performs the registration processing of the telephone (2), and confirms that the telephone (2) is connected to the storage unit (11). Write the information shown. After that, the registration process is periodically performed based on the above information, and the registration process that takes about 2 to 3 seconds each time the handset of the telephone (2) is lifted is not performed.

In this example, as compared with the conventional cellular radio telephone apparatus, only the program of the storage unit (11) needs to be changed, and the effect of the present invention can be obtained without increasing the hardware cost.

A third embodiment will be described with reference to the drawings. Third
In this embodiment, the registration process is performed by the intention of the operator. FIG. 3 is a block diagram of the third embodiment. FIG.
Is the one in which the connection detection unit (7) in FIG. 1 is stopped and a registration key (20) is added to the operation unit. The registration key (20) is attached to a toggle switch (not shown) whose contacts open and close each time it is pressed. The control unit (10) detects opening / closing of the toggle switch, and if "open", the registration process of the telephone (2) is not performed, and if "closed", the registration process of the telephone (2) is performed.

In this way, the registration process, that is, whether or not the telephone (2) can be used can be set by the user's intention.
The setting method is easy, and when it is not used, it does not occupy a channel when receiving a call to the telephone (2).
The registration key (20) is not limited to the toggle switch, but may be a tact switch, and the ten keys can be shared by a program.

[0018]

As described above, if the terminal is not connected to the RJ11 interface, the registration process to the base station is not performed.
Even if there is an incoming call to the terminal, the calling operation is not performed, and a finite number of channels can be used without waste.
