Abstract

PURPOSE: To attain dual mode radio communication with excellent operability by detecting a DTME signal from a terminal connecting to an interface and selecting and an analog signal communication or a digital signal communication with a base station. CONSTITUTION: When a terminal equipment 2 connecting to a 2/4-wire conversion section 5 is hooked off, a control circuit 9 recognizes an output of a hook detection section 7 and awaits an input of a DTME signal from the terminal equipment 2. When the signal is received, a DTMF receiver 6 detects it and the control circuit section 9 checks whether the signal is an analog signal or a digital signal and when the signal is neither the analog signal nor the digital signal, the number is discriminated and the detection data are stored tentatively in a storage section 10 as an OR output. When the signal is an analog signal, MSG data in the storage section 10 are set to be 00000, and when the signal is a digital signal, MSG data in the storage section 10 are set to be 00010, and dial processing is conducted. In this case, the MSG data are used to make request of analog or digital communication to the base station. Thus, the analog or digital communication is set by the DTME signal not effecting the opposite number.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device suitable for including a dual mode wireless telephone device and an RJ11 interface.

[0002]

2. Description of the Related Art A dual mode radio telephone device and RJ11
A communication device having an interface (for example, the interface disclosed in Japanese Examined Patent Publication No. 4-16982) uses either an internal telephone or a terminal (for example, an external telephone, a facsimile, a modem, etc.) via an RJ11 interface. Used to communicate with the base station. This base station includes a base station capable of only analog communication and a dual mode base station capable of both analog and digital communication. Dual-mode radiotelephone devices can communicate with dual-mode base stations, usually internal channels use digital channels, terminals use external digital channels, and terminals use facsimile or modem analog channels. To do.
The designation of the voice channel type is performed by setting which one is used in advance and sending this data to the base station at the time of calling.

[0003]

When selecting a voice channel type (analog or digital) using a terminal connected to the RJ11 interface, the setting change of the voice channel type is manually performed by the input unit of the wireless device. It had to be done, and it was not easy to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a state in which a terminal (2) is connected to the communication device (1) of the present invention. The terminal (2) is a general modular type terminal connected to a telephone line by a modular jack, and is, for example, an external telephone, a facsimile (FAX), a personal computer communication device, or the like. The communication device (1) is a dual mode wireless telephone device (3) and an RJ.
11 interface (RJ11 I / F) (4).

The RJ11 interface (4) is an interface that enables a touch tone or pulse dial type telephone adapted to a two-line signal of a telephone line to be adapted to a wireless telephone device. The RJ11 interface (4) consists of a 2-line to 4-line converter (5), a DTMF receiver (6) and a hook detector (7). The 2-wire / 4-wire conversion unit (5) converts a 2-wire signal which is an input / output to / from the terminal (2) and a 4-wire signal inside the main body. The DTMF receiver (6) detects the DTMF signal output from the terminal (2). The hook detection unit (7) detects whether the terminal (2) is off-hook.

The dual mode wireless communication device (3) is configured as follows. (8) is a handset for the main body. A control unit (9) controls each unit based on a program stored in the storage unit (10). Storage unit (10)
Is composed of ROM, RAM, etc., and stores at least the above-mentioned program and setting data (MSG data) whether to use an analog channel or a digital channel. The MSG data is the data name in the call message transmitted from the communication device (1) to the base station at the time of calling, and as shown in the data structure diagram of the call message of FIG.
It is included in the second WordB of the four words. MSG
Data consists of 5 bits, where 00000 indicates an analog channel and 00010 indicates a digital channel.
Reference numeral (11) is an input unit for operating various settings such as input of a telephone number and automatic dialing when the handset (8) is used. (12) is a display unit that displays a telephone number, time, and the like.

Reference numeral (13) is a transmitter, which outputs a signal from the handset (8) or the two-wire / four-wire converter (5) to the RF.
It is encoded and transmitted to the base station via the duplexer (14) and the antenna (15). Reference numeral (16) is a receiving unit, which receives an RF signal from a base station via an antenna (15) and a duplexer (14), converts the signal into a baseband signal, and then a handset (8) or two-wire four-wire Output to the conversion unit (5). The duplexer (14) enables the antenna (15) to be used for both reception and transmission. The transmission unit (13) and the reception unit (16) can perform analog and digital transmission / reception processing, and perform either one of transmission / reception processing under the control of the control unit (9). Reference numeral (17) is a switch unit, which connects the transmitter unit (13) and the receiver unit (16) to the handset (8) or a two-wire to four-wire conversion unit (5).
It is a switch unit for switching whether to connect to.

The present invention provides an RJ11 interface (4).
The present invention relates to a setting method for analog communication or digital communication when a call is made from a terminal connected to. FIG. 3 is a flow chart showing a call-out operation of the control circuit (9) in the case where a call-out operation is performed by analog / digital designation after a telephone number, and the operation will be described based on this.

When the terminal (2) connected to the 2-wire / 4-wire conversion unit (5) is off-hooked, the control circuit (9) recognizes this by the output of the hook detection unit (7) (Y in S1).
ES). Then, it enters a waiting state (S2) for inputting a DTMF signal from the terminal (2). The DTMF signal consists of numbers 0 to 9, * and #. The numbers 0-9 are the other party's telephone numbers, *
Indicates an analog channel and # indicates a digital channel. D
When the DTMF receiver (6) detects the TMF signal, the control unit checks whether the detected data is * or # (S3, S4). If neither * nor # (N in S4
O) determines that it is the telephone number of the other party, and temporarily stores this detection data in the storage unit (10) by logical sum (buffering S5), and returns to step S2. That is, the telephone numbers are stored by adding the pressed numbers one after another. If the detection data is *, the MSG data in the storage unit (10) is set to 0.
After setting 0000 (YES in S3), the process proceeds to the calling process in step S8. If #, MSG data is 00010
Then (YES in S4), the process proceeds to the calling process in step S8. In step S8, the MSG data necessary for the calling message and the number of the buffered partner are read out,
Causes the base station to send a call message. At this time, MS
If the G data is 00000, the base station is requested to communicate through the analog channel. Similarly, 000
If the value is 10, the base station is requested to communicate via the digital channel.

As in the above example using * and #, the analog channel or the digital channel can be set by the DTMF signal that does not affect the telephone number of the other party.

[0013]

When a call is made from the terminal connected to the RJ11 interface, the terminal side can perform setting operation as to whether the communication with the base station is analog or digital. As a result, the setting operation does not have to be performed on the main body of the wireless telephone device, and it is possible to provide a convenient dual mode wireless telephone device.
