Description

本発明は、PBX内線電話機の履歴発信方式に関し、特に、使用者が局線捕捉を意識しなくても、着信履歴あるいは発信履歴を利用して正しく発信できるようにしたPBX内線電話機の履歴発信方式に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a history transmission system for a PBX extension telephone, and more particularly, to a history transmission system for a PBX extension telephone that allows a user to make a correct call using the incoming call history or the transmission history without being aware of the acquisition of the office line About.

PBX内線電話機には履歴発信機能を備えたものがある。この履歴発信機能を利用すれば相手電話番号をいちいち入力する必要がなく、着信履歴あるいは発信履歴を表示させて選択操作することで簡単に発信できる。図7は、従来の着信履歴発信の動作の概略説明図である。   Some PBX extension telephones have a history transmission function. If this history transmission function is used, it is not necessary to input the other party's telephone number one by one, and it is possible to easily make a call by displaying the incoming call history or the outgoing call history and performing a selection operation. FIG. 7 is a schematic explanatory diagram of a conventional incoming call history transmission operation.

まず、相手電話機(発信者番号「03-5370-XXXX」)から公衆網(電話網)3および主装置2を通してPBX内線電話機(以下、端末と称する。)1に着信があると、公衆網3を介して通知される発信者番号「03-5370-XXXX」は端末1内のメモリに着信履歴として記憶される。   First, when there is an incoming call from the other party telephone (caller number “03-5370-XXXX”) to the PBX extension telephone (hereinafter referred to as a terminal) 1 through the public network (telephone network) 3 and the main unit 2, the public network 3 The caller number “03-5370-XXXX” notified via the URL is stored in the memory in the terminal 1 as an incoming call history.

端末1より着信履歴発信を行う場合、着信履歴表示より「03-5370-XXXX」を選択して発信を行う。このとき、局線捕捉状態でなければ、局線アクセス番号、例えば「0」により局線を捕捉した後に発信者番号が送出されるようにする必要がある。
特開2002−77360号公報
When making an incoming call history transmission from the terminal 1, select "03-5370-XXXX" from the incoming call history display to make a call. At this time, if the station line is not captured, it is necessary that the caller ID is transmitted after the station line is captured by the station line access number, for example, “0”.
JP 2002-77360 A

しかしながら、局線捕捉を行うことなく、履歴発信機能を利用して発信を行うと誤接続が生じることがあるという課題がある。例えば、上記例で端末1が局線捕捉状態にないにも拘わらず局線捕捉を行わずに、着信履歴表示より単に「03-5370-XXXX」を選択して発信を行うと、最初の番号「0」は局線アクセス番号であると認識されてこれにより局線捕捉がなされ、続く「35370XXXX」が発信者番号として誤ダイヤルされてしまう。   However, there is a problem in that an erroneous connection may occur if a call is transmitted using the history transmission function without capturing a station line. For example, in the above example, if the terminal 1 does not capture the station line even though it is not in the station line acquisition state, simply select “03-5370-XXXX” from the incoming call history display and make a call. “0” is recognized as an office line access number, thereby capturing the office line, and subsequently “35370XXXX” is erroneously dialed as a caller ID.

本発明は、上記課題を解決し、使用者が局線捕捉を意識しなくても、着信履歴あるいは発信履歴を利用して正しく発信できるようにしたPBX内線電話機の着信履歴発信方式を提供することにある。   The present invention solves the above-mentioned problems and provides an incoming call history transmission method for a PBX extension telephone that allows a user to make a correct call using an incoming call history or an outgoing call history even if the user is not conscious of catching a local line.

以下、図面を参照して本発明を説明する。図1は、本発明が適用される電話交換システムを示すブロック図であり、基本的には図7と同様に、端末1を収容する主装置2が公衆網3に接続された構成を有する。   The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a telephone exchange system to which the present invention is applied, and basically has a configuration in which a main apparatus 2 accommodating a terminal 1 is connected to a public network 3 as in FIG.

端末1は、端末全体の制御を行う制御部11、着信時に発信者番号を履歴情報として記憶し、さらに着信時の局線アクセス番号を記憶するメモリ12、発信時に相手先番号などを表示する表示部13、履歴発信キーを含む操作部14、および主装置2と接続するための入出力インタフェース(I/F)15を備える。その他、送話器、受話器なども備えるが図示省略している。   The terminal 1 has a control unit 11 that controls the entire terminal, stores a caller ID as history information when receiving a call, and further stores a memory 12 that stores a local line access number when receiving a call, and displays a destination number when calling Unit 13, an operation unit 14 including a history transmission key, and an input / output interface (I / F) 15 for connecting to main device 2. In addition, although a transmitter, a receiver, etc. are provided, they are not shown.

着信時、メモリ12に発信者番号を履歴情報として記憶することにより、着信時に得られた発信者番号に基づく着信履歴発信を行うことができるが、発信時、相手先番号を履歴情報としてメモリ12に記憶すれば、発信時に得られた相手先番号に基づく発信履歴発信も行うことができる。   By storing the caller number as history information in the memory 12 at the time of an incoming call, it is possible to make an incoming history call based on the caller number obtained at the time of the incoming call. , It is possible to perform outgoing call transmission based on the destination number obtained at the time of outgoing.

主装置2は、主装置全体の制御を行う制御部21、交換における各種設定情報を記憶するためのデータベース22、端末1や局線等外部機器を接続するための入出力I/F23を備える。データベース22には、局線に対応して局線アクセス番号も記憶されている。   The main device 2 includes a control unit 21 that controls the entire main device, a database 22 for storing various setting information in exchange, and an input / output I / F 23 for connecting an external device such as the terminal 1 or a station line. The database 22 also stores office line access numbers corresponding to the office lines.

端末1において操作部14が操作されてその状態が変化したとき、主装置1から端末1に、図2に示すように、端末1の状態が通知される(S1)。ここで通知される端末1の状態には、空き状態、内線捕捉状態、内線通話状態、局線捕捉状態、局線通話状態などがある。これにより、端末1は、自装置の現在の状態を認識できる。   When the operation unit 14 is operated in the terminal 1 and its state changes, the state of the terminal 1 is notified from the main apparatus 1 to the terminal 1 as shown in FIG. 2 (S1). The state of the terminal 1 notified here includes an idle state, an extension acquisition state, an extension call state, a station line acquisition state, a station line call state, and the like. Accordingly, the terminal 1 can recognize the current state of the own device.

図3は、相手端末から端末1へ着信があった時の動作を示す図である。着信時、主装置2には相手端末から公衆網3を介して発信者番号が通知される(S2)。制御部21は、着信した局線に対応する局線アクセス番号をデータベース22から読み出す(S3)。これにより読み出された局線アクセス番号は、入出力I/F23を介して、公衆網3から通知された発信者番号とともに端末1に通知される(S4)。   FIG. 3 is a diagram illustrating an operation when an incoming call is received from the partner terminal to the terminal 1. When receiving an incoming call, the main apparatus 2 is notified of the caller number via the public network 3 from the partner terminal (S2). The control unit 21 reads the office line access number corresponding to the incoming office line from the database 22 (S3). The office line access number thus read is notified to the terminal 1 together with the caller number notified from the public network 3 via the input / output I / F 23 (S4).

端末1のメモリ12は、主装置2から通知された発信者番号を着信履歴情報として記憶し、さらに通知された局線アクセス番号を記憶する(S5)。   The memory 12 of the terminal 1 stores the caller number notified from the main device 2 as incoming call history information, and further stores the notified office line access number (S5).

図4は、端末1から相手端末へ発信した時の動作を示す図である。端末1において操作部14が操作されて局線発信および相手先番号がダイヤルされると、それらの情報は主装置2の制御部21に送出される(S6)。表示部13には相手先番号が表示部13に表示され、局線が捕捉されればその旨も表示される。   FIG. 4 is a diagram illustrating an operation when a call is transmitted from the terminal 1 to the partner terminal. When the operation unit 14 is operated in the terminal 1 and the local line transmission and the destination number are dialed, such information is sent to the control unit 21 of the main apparatus 2 (S6). The other party number is displayed on the display unit 13 on the display unit 13, and if the station line is captured, this is also displayed.

制御部21は、局線を捕捉し、相手先番号をダイヤル発信させるとともに、データベース22から発信中の局線の局線アクセス番号を読み出す(S7)。これにより読み出された局線アクセス番号は相手先番号とともに、入出力I/F23を介して端末1へ通知される(S8)。   The control unit 21 captures the station line, dials the destination number, and reads the station line access number of the station line being transmitted from the database 22 (S7). The station line access number read out is notified to the terminal 1 through the input / output I / F 23 together with the destination number (S8).

端末1のメモリ12は、主装置2から通知された相手先番号を発信履歴情報として記憶し、さらに局線アクセス番号を記憶する(S9)。   The memory 12 of the terminal 1 stores the destination number notified from the main device 2 as outgoing call history information, and further stores the office line access number (S9).

以上のようにして、端末1のメモリ12は、着信時には公衆網から通知される発信者番号と局線アクセス番号を記憶し、発信時には端末1でダイヤルされた相手先番号と局線アクセス番号を記憶する。   As described above, the memory 12 of the terminal 1 stores the caller number and the office line access number notified from the public network when receiving a call, and stores the destination number and the office line access number dialed by the terminal 1 when making a call. Remember.

図5は、端末1からの履歴発信の動作を示す図である。端末1において操作部14が操作されて表示部13の着信履歴あるいは発信履歴の表示に基づく履歴発信操作が行われると(S10)、端末1が空き状態にあれば、制御部11は、メモリ12から局線アクセス番号と該当する履歴情報、すなわち発信者番号または相手先番号(以下、履歴ダイヤルと称す。)を呼び出し(S11)、履歴ダイヤルの前に局線アクセス番号を付加して主装置2に送出する(S12)。   FIG. 5 is a diagram showing an operation of history transmission from the terminal 1. When the operation unit 14 is operated in the terminal 1 and a history transmission operation based on the display of the incoming history or outgoing history on the display unit 13 is performed (S10), if the terminal 1 is in an empty state, the control unit 11 stores the memory 12 From the main line 2 by calling the station line access number and the corresponding history information, that is, the caller number or the destination number (hereinafter referred to as history dial) (S11), and adding the station line access number before the history dial. (S12).

主装置1は、端末1から送出された局線アクセス番号に該当する局線を捕捉し、続いて履歴ダイヤルを発信する。このとき、端末1の表示部13に履歴ダイヤルとともに局線アクセス番号を表示させたり、履歴ダイヤルとともに局線捕捉状態になった旨の表示を行わせたりすることができる。履歴ダイヤルの表示と局線アクセス番号の表示、履歴ダイヤルの表示と局線捕捉状態になった旨の表示は別個の手段(LCDとLEDなど)でもよい。   The main device 1 captures the office line corresponding to the office line access number sent from the terminal 1, and then sends a history dial. At this time, the station line access number can be displayed together with the history dial on the display unit 13 of the terminal 1, or the fact that the station line has been captured can be displayed together with the history dial. A separate means (LCD, LED, etc.) may be used for the history dial display and the office line access number display, and the history dial display and the office line capture state display.

上記は端末1が空き状態の場合であるが、端末1が内線捕捉状態にある場合も同様に端末1から局線アクセス番号が先頭に付加された履歴ダイヤルが主装置2に通知され、主装置2は、通知された局線アクセス番号で局線を捕捉し、履歴ダイヤルを発信する。   The above is a case where the terminal 1 is idle, but when the terminal 1 is in the extension acquisition state, the terminal 1 similarly notifies the main apparatus 2 of the history dial with the office line access number added to the head, and the main apparatus 2 2 captures the office line with the notified office line access number and sends a history dial.

端末1が既に局線捕捉状態にある場合には、端末1から主装置2への局線アクセス番号の通知は不要である。この場合には、局線アクセス番号を付加することなく履歴ダイヤルだけを端末1から主装置2へ通知し、主装置2は、通知された履歴ダイヤルを発信する。なお、端末1が内線通話状態や局線通話状態にある場合には履歴発信操作を無効とする。   When the terminal 1 is already in the station line acquisition state, the notification of the station line access number from the terminal 1 to the main apparatus 2 is not necessary. In this case, only the history dial is notified from the terminal 1 to the main apparatus 2 without adding the office line access number, and the main apparatus 2 transmits the notified history dial. When the terminal 1 is in the extension call state or the office line call state, the history call operation is invalidated.

図6は、本発明による着信履歴発信動作をまとめた概略説明図である。まず、相手端末(発信者番号「03-5370-XXXX」)から公衆網3および主装置2を通して端末1に着信があると、主装置2は発信者番号「03-5370-XXXX」とともに局線アクセス番号、例えば「9」を端末1に通知する。端末1は、通知されたに発信者番号「03-5370-XXXX」を着信履歴情報として記憶し、さらに局線アクセス番号「9」を記憶する。   FIG. 6 is a schematic explanatory diagram summarizing the incoming call history transmission operation according to the present invention. First, when there is an incoming call from the other terminal (caller number “03-5370-XXXX”) to the terminal 1 through the public network 3 and the main device 2, the main device 2 sends a local line together with the caller number “03-5370-XXXX”. An access number such as “9” is notified to the terminal 1. The terminal 1 stores the notified caller number “03-5370-XXXX” as incoming call history information, and further stores the office line access number “9”.

端末1より着信履歴発信を行う場合、着信履歴表示より「03-5370-XXXX」を選択して発信を行う。このとき、端末1が空き状態あるいは内線捕捉状態にあれば、局線アクセス番号「9」が着信履歴の発信者番号「03-5370-XXXX」の前に付加されて端末1から主装置2に通知される。主装置2は、局線アクセス番号「9」で局線捕捉し、発信者番号「035370XXXX」を発信する。   When making an incoming call history transmission from the terminal 1, select "03-5370-XXXX" from the incoming call history display to make a call. At this time, if the terminal 1 is in the idle state or in the extension acquisition state, the office line access number “9” is added before the caller number “03-5370-XXXX” in the incoming call history, and the terminal 1 transfers to the main device 2. Be notified. The main device 2 captures the station line with the station line access number “9” and transmits the caller number “035370XXXX”.
