Description

[Detailed description of the invention] [Industrial field of application] The present invention is a button telephone device that accumulates and stores call usage such as call charges, and displays the cumulative call usage during a call based on this content. It is related to.

[Conventional technology]

In recent key telephone devices, when accommodating multiple outside lines, charging lines from which charging signals arrive are mixed, and when making a long distance call or a third party's paid call, etc., the charging line is used. It shall be designated as a specific outside line, and in addition to making calls and making calls using this line, the amount of call usage required for one call will be accumulated in the memory, and the accumulated amount of call usage will be displayed during the call based on the contents of this. Efforts have been made to facilitate the management of call charges, and details are disclosed in, for example, Japanese Patent Laid-Open No. 60-236350.

In other words, in the same publication, data on call charges is stored in memory and displayed based on the contents, but this content is cleared by selecting and capturing an arbitrary outside line. Even if there is no response to an outside line call due to the other party being busy, etc., the memory contents are cleared and preparations are made for the next outside line call and start of the conversation.

[Problem that the invention attempts to solve]

However, the call usage using a specific outside line often needs to be confirmed after the call ends, and with the above-mentioned configuration, if the outside line is captured by another key telephone before checking the call usage, The contents of the memory have already been cleared, creating a problem in which it is impossible to check the call charges.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention is constructed by the following means.

That is, a call usage memory for accumulating and storing the call usage of a specific outside line call is provided in correspondence with the pushbutton telephone with a display, and based on the contents of the call usage memory, the call usage is calculated by the pushbutton telephone with a display during a call. The button telephone device that displays the call usage of the call includes a determining means for determining whether an outside line captured by the button telephone with a display is a specific outside line, and a determining means for determining whether the outside line captured by the button telephone with a display is a specific outside line based on the determination output of the determining means. a clearing means for clearing the call usage amount memory when a call is started by a button; a detection means for detecting the last call usage display operation by a button telephone with a display device in an idle state; and a detection means for detecting call usage according to the detection output of the detection means. The present invention is provided with a control means for reading the immediately preceding call usage amount from the data memory, switching the display data from the idle state display data to the call usage amount, and transmitting the data to the button telephone with display.

[Effect]

Therefore, the contents of the call usage memory provided for a pushbutton telephone with display are retained until the telephone acquires a specific outside line and starts a call, and the telephone is in an idle state based on the contents of the memory. By performing a specific display operation at this time, the previous call usage amount will be displayed on the display of the telephone.

Note that the SRC 34 has a power separation function, extracts the power supplied from the KSU 1 side via the signal line 33, stabilizes it, and supplies it as a local power V to each part that requires it.

Therefore, when off-hook is performed in any ST4, the operation data of this is transferred to the CPU 14.
The key operations in KB37 are also the same, and the CPU 14 outputs TSW1 according to the operation of the outside line key or extension key and the operation of the dial key.

For each area set up for call usage aggregation and accumulation, call usage such as call frequency and call charges are sequentially added and accumulated, and the call usage is memorized and stored. ST in call
In addition to displaying the cumulative call usage amount for ST 4 by DGP, in response to the prescribed operation of each ST 4 ₁ to 4 _n ,
The corresponding contents are read out and displayed using DGP.

FIG. 1 is a diagram showing the contents of the RAM 16,
Total tally area (hereinafter referred to as TSE) 21 for adding and storing the total call usage of external lines 2 ₁ to 2 _o ;
External lines 1 and 2 _o are provided corresponding to each of external lines 2 ₁ to 2 o, and are used to add and store each individual call usage amount.
Individual tally area - outside line n/individual tally area (hereinafter referred to as LSE) 22 ₁ to 22 _o , ST4 ₁ to 4 _n , and a telephone set 1 that adds and stores the usage of each individual outside line call.・Individual aggregation area ~ Telephone _o・Individual aggregation area (hereinafter referred to as SSE) 23 ₁

24 ₁ to 24 _n etc. are available, and with these,
It is assumed that the usage amount of each call is stored.

However, in FIG. 1, if all of the outside lines 2 ₁ to 2 _o are charging lines where charging signals arrive,
Assuming that all ST4 ₁ to 4 _n have DGP, LSE22 ₁ to 22 corresponding to these
_o , _SSE231 to _23n , and _SME241 to _24n , but under conditions where the number of specific outside lines and the number of STs having DGP are small, the number of each area may be determined accordingly.

FIG. 3 is a flowchart showing the storage control status of call usage by the CPU 14, in which the presence or absence of a billing signal is determined based on the "billing signal?"101;
If this is N (NO), "other input signal response processing"
102, while step 101 is Y.
(YES) If the outside line is a “billing line?”1
11 is determined according to the setting data in the RAM 16, and when the determination result is Y, the external line in question is a specific external line, and the billing signal for which step 101 is Y is the "first signal after transmission?" 112. Judging, this is Y
If so, the call is started, and ``corresponding SME, clear, initial value set'' 113 is performed, and the contents of this are transmitted to the corresponding ST4 and displayed by DGP, ``charging display start processing'' 112 is performed.

In addition, in response to N in step 112, the second and subsequent billing signals have arrived, and the "applicable SME/addition"
121, and ``accounting display update'' 122 is performed based on the contents.

Next, "TSE/addition" 13 for TSE21
1 and then the corresponding LSE22 and SSE
“Applicable LSE/Addition” for 23, 132, “Applicable
Step 101 and subsequent steps are repeated via ``End'' and other routines.

Therefore, in response to the arrival of the charging signal, it is necessary to respond accordingly.
In each of LSE22, SSE23, and SME24,
As the call usage amount is sequentially added, integrated, and stored, the contents of the TSE 21 are also sequentially increased, and the total outside line call usage amount for the entire device is added and stored.

FIG. 4 is a flowchart of a situation in which the CPU 14 performs display control based on the contents of the SME 24, and is performed in response to reception of operation data from the ST 4 having the DGP.

That is, the operation data determines "Memory key operation?" 201 in KB37, and if this is Y, checks "On-hook state?" 202 based on the status data in RAM 16, and depending on N of this, "Other state?" If step 202 is also Y, ``set accumulation confirmation flag'' 204 is performed, and steps 201 and subsequent steps are repeated via ``End'' and other routines.

Similarly, when step 201 is N, "Relay key operation?" 211 in KB37 is determined, and if this is also N, "Other key response processing" 21 is determined.
2, when step 211 is Y, check ``On-hook state?'' 221 as in step 202, and in response to step 204, check ``Set accumulation checking flag?'' 222. Check.

Note that if either step 221 or 222 is N, the process moves to "relay key processing in other states" 223.

On the other hand, if all of steps 211, 221, and 222 are Y, it means that ST4 is in the idle state and the last call usage display operation has been performed, and the contents of the corresponding SME24 are read and From the data displayed by DGP,
Switch to the content of SME 24 and send it as display data to ST4, perform "Display applicable SME/content" 231, display the last call usage amount to DGP of ST4, and then perform steps corresponding to step 204. ``Reset flag during integration confirmation'' 232 is performed.

Therefore, in this example, if the memory keys in the KB 37 are sequentially operated in the idle state of on-hook, the DGP will display the cumulative call usage by the immediately preceding specified external line stored in the ST 4 and the corresponding SME 24. This can be verified.

In addition, the contents of SME24 are preserved by the corresponding ST4 until the next call using a specified outside line is started, so they are not cleared unnecessarily.
The above-mentioned operation does not cause any trouble in confirmation.

However, for the stored content and display, numbers indicating call usage such as call charges and call frequency may be used depending on the conditions, and charging signals from the outside line 2 are not used.
Various modifications are possible, such as generating a charge counting signal using a timer or the like and using the call usage amount based on autonomous billing.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the amount of call usage immediately before using a specific outside line is saved until the next call using the specific outside line is started, and the amount of call usage accumulated during one call is stored in this way. It can be confirmed reliably and easily after the end of the call, and a great effect can be obtained in various key telephone devices that manage call charges for specific outside lines.
