Abstract

PURPOSE:To connect a master set connected to plural telephone sets in radio to plural trunk lines by connecting plural radiotelephone sets and connecting devices in radio and using a controller connected to the connecting devices with cables and connected to the plural trunk lines. CONSTITUTION:The radiotelephone system is constituted by the controller 12 connected to the plural trunk lines 11, the plural connecting devices 13 connected to the controller, and plural radiotelephone sets connected respectively to the connecting device via a radio line 14. When an incoming call exists to one of the trunk lines 11, the controller 12 detects a call signal, transmits an incoming signal A to one of the connecting device 13 and transmits an incoming signal B including a connecting device identification number specific to the connecting device as signal infomation to the radiotelephone set side. A radiotelephone set responding to the said sigal by hook-off transmits an incoming response signal C as the specific identification number signal iformation to the connecting device to set the radio line with the connecting device.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a plurality of telephones for connection to one or more central office lines, a main telephone connected to the central office line for controlling these telephones, and The present invention relates to a wireless telephone system in which the first part between the base unit and the telephone of a telephone device is made wireless, thereby increasing the convenience of the telephone device.

[Prior Art] FIG. 1 is a block diagram showing an example of the configuration of a conventional telephone device consisting of a plurality of telephones for connection to a plurality of office lines and a base unit for controlling these telephones. .

In FIG. 1, when there is an incoming call on any of the central office lines 1, Jll! fi2 detects the 16Hz ringing signal related to the incoming call, controls multiple telephone charges 3, and rings these bells, etc. 1III. Then, when the user answers from any telephone, the base unit turns on the line relay of the office line corresponding to this telephone, thereby making a call.

On the other hand, when one of the plurality of telephones 3 makes a call, the parent 2 detects the call signal from the telephone and calls the station number.
A call is made by turning on any of the line relays a1.

[Problem that the invention seeks to solve, α]

Conventional telephone devices of this type require a large number of lines, such as a call line, a control signal line, and a lamp line for displaying the status of the return line or extension line on the telephone to communicate with multiple telephones. Therefore, the wired part between the base unit and the phone is a multi-core cable, which takes time and effort to install, and the cost of the cable is also high. The drawback was that it was difficult to move the 82 and telephone.

In addition, in order to deal with these drawbacks, a system that connects the base unit and telephone wirelessly is being considered, but this type of telephone device using the conventional wireless system cannot support multiple central office lines. The drawback was that it was not possible.

In order to eliminate these drawbacks, the present invention aims to provide a wireless telephone system in which a base unit that is wirelessly connected to a plurality of telephones can be connected to a plurality of office lines.

Hereinafter, the groove bottom and the like of the present invention will be explained in detail based on the drawings of the embodiments.

〔Example〕

FIG. 2 is a block diagram showing the v1 configuration of one embodiment of the present invention.

In Figure 2, originally #iT! In the L talk system, multiple stations #
111, a plurality of connection devices RA13 connected to this i1i+ control device, and a plurality of wireless telephones 15 and 5 connected to these connection devices via wireless lines 14, respectively. has been done. Here, when there is an incoming call at one of the stations Mll, the control device 12
detects a 16 Hz calling signal and sends an incoming call signal A to one of the connecting devices 13. The connecting device that has detected this incoming call signal sends an incoming call signal B that includes a connecting device identification number unique to the connecting device as signal information to the wireless telephone system. Among the multiple wireless telephones that have detected this incoming call signal B, the one that has responded by hook-off has a connection device identification number unique to the connection device and a phone g identification number unique to the wireless telephone. An incoming call response signal C containing the signal information as signal information is sent to the connection device, and a wireless line is set up with the connection device. The connecting device that detected this incoming call response number C sends an incoming call response signal to the Ril control device 12, and then the control device that detected this incoming call response signal sends the incoming call response signal to the Ril control device 12. By turning on the line relay,
6. On the other hand, when a call is made from a wireless telephone, the wireless telephone with the 7. A calling signal E including a device identification number as signal information is sent to the connected device side.The connecting device that detects the second calling signal E sends a calling response including a connecting device identification number unique to the connected device as signal information. The signal F is sent to the wireless telephone, a wireless line is set up with the wireless telephone, and the calling signal G is sent to the control device, and the control device that detects the calling signal G connects the central office line. By turning on the relay, a call is made from a wireless telephone.

FIG. 3 is a block diagram showing the configuration of another embodiment of the present invention.

In FIG. 3, this wireless telephone system has an extension line connecting device 21 in addition to a central office line connecting device as a connecting device.
Originally M? 1. In addition to the operation explained in Figure 2, there is also an extension connection like this. It is possible to configure a configuration in which communication connections between internal IQa are also performed via the A location.

On the other hand, in a telephone system that uses wireless lines, for example, a configuration is adopted in which multiple call channels and a common control channel for connection control separate from the call channels are provided, and connection control is performed using the control channel. In this case, radio wave interference may occur when multiple connection operations occur at the same time, but in the configuration shown in Figure 2 or 3, the This kind of radio wave interference can be avoided by restricting the incoming and outgoing call connection operations of connection devices other than the connection device during mutual call connection operations, or the call connection operations between extension lines.

In addition, in the configuration shown in FIG. 2 or 3, by sending a control signal including information on the office line or internal μλ in use from the control device 12 to the wireless telephone via the connection device 13, If a wireless telephone other than the wireless telephone in question is notified of the central office line or extension in use, no matter where the individual wireless telephone is within the service area, the user will be able to check the central office line or extension on the display on the wireless telephone side. You can know the usage status of.

〔Effect of the invention〕

As explained above in detail, according to the method of the present invention,
Since it is possible to connect multiple telephones and wirelessly connected parents (6) to multiple return lines, and because the telephone 1 and the configuration are connected wirelessly, this has been a problem in the past. This eliminates the need for multi-core cables containing many wires such as communication lines between the configuration and multiple telephones, and lamp wires for displaying the status of the station or extension on the telephone using lamps, etc., making sterilization work easier. It has the advantage of being greatly simplified, eliminating the need for multiple cable costs, and making it easy to change the configuration and location of the telephone.
