Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is used within a certain area such as a golf course, construction site, or factory, and is composed of a plurality of slave units and one or more master units. This article relates to a cordless telephone system that allows users to see the charges for calls made to outside lines by these cordless handsets.6 [Conventional example] In recent years, cordless telephones have been proposed by various manufacturers as new home appliance products. has been done. A cordless telephone consists of a connection device (base unit) and a handset (slave unit) that are connected to a telephone line, and signals such as calls, ID codes, voice communications, etc. are transmitted and received by radio waves between them. Therefore, the connection device is equipped with a radio wave transmitting and receiving function, and the handset also has a built-in radio wave transmitter and receiver. In other words, the other party's voice is converted from an electrical signal to a radio wave signal by the connecting device and sent to the handset. Conversely, a voice signal transmitted by radio waves from a handset is converted from a radio wave signal to an electrical signal by the connecting device, and then transmitted to the other party via a line.

[Problem to be solved by the invention] The above-mentioned cordless telephones include a low power type for home use and a low power type for business use, but in both cases, the base unit and slave unit correspond on a one-to-one basis. , it is not possible to use multiple handsets.

Therefore, the base unit may be one, and the slave units may be N (any number), or the base unit may be M (any number), and the slave units may be N.
Cordless telephone systems have been proposed for use in, for example, golf courses in certain areas, construction sites, event venues, and various recreational facilities.

However, in the above-mentioned cordless telephone system, it is possible to make calls not only between the handset and other handsets or other extensions, but also with outside lines, so it is necessary to add a billing function to calculate charges for the use of outside lines by the handset. However, in the already known billing function, the billing calculation unit is based on the call time by the extension terminal, so if there are multiple handsets using one extension terminal, it is difficult to determine which handset is charged how much for the call. A problem arises in that it is not possible to determine whether or not it has been used.

This invention has been made in view of the above-mentioned problems, and its purpose is to provide a cordless telephone system that can calculate charges for the usage time of each handset when an outside line is used by a plurality of handsets. It is in.

[Means for Solving the Problems] In order to achieve the above object, the cordless telephone system of the present invention includes a plurality of handsets used within a predetermined area, and a communication system between the handsets placed in the area and the handsets. Call with ID
Calculate at least one or more base units that perform cord and voice communications, etc., the exchange function that connects this base unit with a wired line, and connects the slave unit with an extension or outside line, and the call charges for this outside line. and a billing interface circuit that inputs handset information from the parent device via the wired line and converts this information into a format for the billing process,
When the slave unit uses an outside line, the base unit sends a "0" call to the switching equipment via the wired line, and sends information on the slave unit using the outside line to the billing interface circuit, The switching equipment switches to an outside line and activates the billing function, and when the usage of the outside line ends, the charging interface circuit sends the information to the switching equipment, and this switching equipment switches to the predetermined line and the slave unit. The main point is that the information and call charges due to billing processing are stored.

[Function] With the above configuration, when each handset uses an outside line, in the switching equipment, the billing function is activated and the charge for one call is calculated in addition to the connection to the outside line, and the charge for the call is calculated based on the extension number used. The number and handset information (ID code) are stored.

In this way, since the per-call charge and the ID code of the handset are stored, it is possible to determine which handset is using what line, and
You will be able to see how much call charges you have used.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

In Figure 1, a predetermined area (for example, the site of a golf course, etc.)
For example, a base unit (connection device) 1 is provided, and a slave unit (handset) 21.22°...t2N is provided in the area.
There are now multiple , and base unit 1 is connected to a wired line (
It is connected to an exchange device 4 via an extension (extension line) 3. In addition, the switching device 4 includes a switching device 4a and a known function (
In addition to a predetermined line (extension number) of the wired line, information on each handset 21, 22, . Note that an extension line and an outside line are connected to the exchange 4a.

In the billing system 4b, data for each region is stored in advance because call charges differ depending on the region of the outside line used.
When using an outside line, charges are calculated based on the data and usage time. Furthermore, a billing interface circuit 5 is connected to the wired line 4, and this billing interface circuit 5 constantly monitors the wired line 4 and determines whether the handset 21122 is sent from the base unit 1. . . . It has a function of inputting t2N information, converting the information into the format of the billing system 4b, and sending it to the switching equipment 4.

The base unit 1 has a wireless control function for transmitting and receiving signals such as ID codes and voice communication to and from the slave units 21, 2□, . , 110 F1 call request handset information (
For example, an ID code, etc.) and a wired control function for outputting the information to the billing interface circuit 5.

On the other hand, slave units 21, 22. ... t2N is equipped with a display section (for example, a liquid crystal display section), and this display section shows the power state 1.
Call status and information are displayed.

As a further supplement, the above cordless telephone system:
A duplex system is adopted, and voice communication including various data transmissions within the voice band is performed.

Next, we will explain the operation of the cordless telephone system with the above configuration in a second manner.
The explanation will be based on the time chart shown in the figure.

First, when it is assumed that an external line is used at the specified handset (IDOI) 21, when using the external line, the handset (IDOI) 21
0L) 2□0 When the call button is pressed, the handset (IDO)
I) A call request is made in 2, a response call is made on an empty channel with base unit 1, and the caller handset (IDO)
I) 2. and base unit 1 are brought into a linked state via a wireless line.

At this time, the code (IDOI) of the linked slave device 21 is stored in the base device 1. On the other hand, the calling device (
100L) In 2□, following the call button operation described above, the designated dial number is pressed using the pushbutton button, but since an outside line is being used, "0" is first dialed (
(External line request) is placed (shown at A in the figure). Then,
The "07+ call" is sent from the base unit 1 to the exchange equipment 4 via a predetermined line (predetermined extension number) of the wired line 3 (as shown in B in the figure), and information on the slave unit 21 (code;
ID0I) is sent to the billing interface circuit 5 via the same predetermined extension (as shown in C in the figure).

Subsequently, in the exchange device 3, the exchange 4a switches the extension line to an outside line, and the billing system 4b is activated to start billing calculation. At this time,
In response to the external line operation of handset 21.

The area of the outside line is determined, and the call charge data for this area is read. Further, when the dial signal for the outside line number is sent to the outside line via the switching equipment 4 and the called telephone goes off-hook, the handset 21 and the called telephone are placed in a conversation state.

Subsequently, when the outside line call is terminated, the billing interface circuit 5 transmits the line used (extension number) and handset 2.
The data of the information (IDOI) of □ is sent in the format of the billing system of the exchange 3 (shown as D in the same figure), and in the billing system 4b, the extension number and ID
Along with the 0L data, the data on the call charges resulting from the 9 billing process will be stored. Therefore, when using an outside line, it is possible to know which handset used how much call charge.

In this way, when the handset 2□, ..., 2N uses an outside line, the billing function of the switching equipment 3 is activated, the call fee is calculated, and the extension number used by the handset and information about the handset are (ID code) etc. are stored.

Therefore, since which handset uses an outside line and its call charges are stored, it is possible to know which handset used what call charge. Also, in response to a request from the handset 21 using an outside line, the stored information is sent to the handset 21,
It may also be displayed on the display section of the handset 21.

In the above embodiment, the case where there are multiple handsets 2□, 2□, ... t2N for one base unit 1 was explained, but the case where there are multiple base units 1 and multiple handsets The same is true even if the base unit 1 is provided with a billing interface circuit 5 corresponding to each base unit 1, so that it becomes possible to know which handset used how much call charge.

Moreover, the handset 21, 2. , . . . Predetermined 1 of wired line 3 at +2N? When making a call to another handset or extension phone (system representative, etc.) via IJ11 (extension), the above-mentioned billing function is not activated and the extension number and handset information are stored in the billing system 4b. There's nothing wrong with that.

[Effects of the Invention] As explained below, the cordless telephone system of the present invention has a billing function that calculates the call fee when the handset uses an outside line, and the calculated call fee is calculated by the handset when using an outside line. Since the extension number used and the information (ID code) of the handset are memorized, it is now possible to know which handset used how much call charge, which is a useful feature that can resolve problems. effective.
