[0002]
[Prior art]
In general, a key telephone system is composed of a main device connected to a telephone line and one or more key telephones connected to the main device. The key telephone detects the key operation and the state of the handset, and transmits the operation information to the main unit. The main unit performs function processing based on the operation information from the key telephone, thereby enabling an external call with the telephone line. Various functions such as extension calls with other key telephones are realized.
In recent years, in offices that use both a key telephone and a personal computer, as one of the configurations of a key telephone system, an information processing terminal such as a personal computer (hereinafter referred to as a PC terminal) is connected to the main device to provide advanced functions. CTI (Computer Telephony Integration) systems are becoming popular.
[0003]
FIG. 15 is a block diagram showing a configuration of a conventional CTI system. Main apparatus 91 is connected to telephone line 90, and each of key telephones 93 </ b> A to 93 </ b> N is connected to main apparatus 91 via extension transmission path 92. Each of the key telephones 93A to 93N is associated with a PC terminal 97A to 97N, and these PC terminals 97A to 97N are connected to the server 95 via a LAN line 96. The main apparatus 91 and the server 95 are connected via a data communication path 94 and exchange various information as necessary.
[0004]
In the server 95, personal information such as name and office is registered as a database in correspondence with the telephone number of the other party. In each of the PC terminals 97A to 97N, the database information of the server 95 connected by the LAN line 96 can be displayed as a list on the screen and searched, and a calling operation to the searched partner can be performed. For example, when a call operation is performed to the other party selected from the list displayed on the screen on the PC terminal 97A, the server 95 extracts the other party telephone number from the database and requests the main apparatus 91 to make a call. In response to this, the main apparatus 91 performs an outside line transmission process based on the other party telephone number as if the transmission operation was performed by the key telephone 93A installed in association with the PC terminal 97A.
[0005]
Further, when the caller telephone number is notified from the telephone line 90 when an outside line is received, the caller telephone number is notified from the main device 91 to the server 95. The server 95 searches the database based on the notified caller telephone number, and obtains personal information about the caller obtained from the key telephone responding to the incoming call, for example, the PC terminal associated with the key telephone 93A. It is displayed on the 97A screen.

When the data transfer means 12B of the main control unit 12 receives information from the server 3, first, a command is acquired from the received data (step 80), and the information is based on the type information and the function processing means of the main device 1 is used. It is determined whether or not it is for use in 12A (step 81).
[0039]
FIG. 10 is an explanatory diagram showing a configuration example of information transmitted from the server. As shown in FIG. 7B, the information includes a command, a telephone ID, and detailed data. For example, the information for instructing the phone book list display is composed of a command “40” corresponding to the instruction, a telephone ID indicating the transmission destination of the information, and detailed data indicating the actual phone book list data.
If the received data is information for use by the function processing means 12A (step 81: YES), the received data is captured and analyzed (step 82), and the corresponding function processing is performed by the function processing means 12A. Execute (step 83).
[0040]
When transmission data to the key telephone 2 is newly generated by the function processing in the function processing means 12A (step 84: YES), among the transmission buffers provided in the extension I / F unit 13, The transmission data is stored in the transmission buffer corresponding to the telephone ID of the key telephone 2 (step 87). As a result, the transmission data is read from the transmission buffer and transmitted to the extension transmission path 20 to which the destination key telephone 2 is connected (step 88). If no new transmission data is generated (step 84: NO), the process is terminated. On the other hand, if the received information is not information to be used by the function processing means 12A (step 81: NO), the telephone ID is deleted from the received data as shown in FIG. 7A (step 74). ), And proceeds to step 87. As a result, the received data is transferred to the key telephone 2 corresponding to the telephone ID.
[0041]
As described above, the main device 1 is provided with the data transfer means 12B, so that the operation information from the key telephone is transferred to the server 3 as necessary, and the information from the server 3 is transferred to the corresponding key telephone 2. The main control unit 12 of the main device 1 does not need to take in all the information and perform analysis processing, thereby reducing the processing load on the main control unit 12 and more data from the server 3 to the key telephone 2. It can be transmitted at high speed and abundant information can be displayed on the key telephone 2 with a short waiting time.
[0042]
Further, since the data transfer means 12B determines whether or not the information transfer is necessary based on the command indicating the instruction content of the received information, the data transfer means 12B includes the information of the information in the information transmitted from the key telephone 2 or the server 3. It is not necessary to separately include transfer destination information for designating a transfer destination, and it is possible to determine whether transfer is necessary or not without increasing the capacity of information to be exchanged. Furthermore, in the data transfer means 12B, the telephone ID is added according to the transmission source of the received data, or the telephone ID is deleted and transmitted to the corresponding extension transmission line. The information of each key telephone 2 can be mixed and communicated between the main apparatus 1 and the server 3 without increasing the amount of information exchanged between the two.
[0043]
Next, the operation of the entire key telephone system according to the present invention will be described with reference to FIG. FIG. 11 is a sequence diagram showing a telephone directory calling operation for calling from a key telephone using a database of the server.
First, when the telephone directory key is pressed on the key telephone 2A operating in the TEL mode (step 100), this operation is detected by the operation input unit 24, and operation information corresponding to this operation is generated by the operation information generating means 22B. Then, the data is transmitted from the transmission I / F unit 21 to the main apparatus 1 via the extension transmission path 20 (step 101).
[0044]
In the main apparatus 1, the extension I / F unit 13 receives this operation information, and the data transfer means 12B determines whether the information is used by the function processing means 12A based on the command. Here, since it is information used by the function processing means 12A, the operation information is taken in, and the telephone book function is executed by the function processing means 12A. First, a telephone directory display request for requesting transmission of telephone directory list data addressed to the key telephone 2A is transmitted to the server 3 via the communication I / F unit 15 and the data communication path 30 (step 102).
[0045]
Before and after this, the main control unit 12A registers that the key telephone 2A has shifted to the CTI mode, and switches from the extension I / F unit 13 to the key telephone 2A via the extension transmission path 20 to switch to the CTI mode. A CTI mode instruction is transmitted (step 103).
The key telephone 2A receives this CTI mode instruction via the transmission I / F unit 21 at time T1, and switches its operation mode from the TEL mode to the CTI mode.
[0046]
The server 3 receives the phone book display request via the communication I / F unit 31, and the server control unit 32A reads out the desired phone book list data from the database 33 and confirms that the information is related to the key telephone 2A. The telephone ID of the indicated key telephone 2A is added and transmitted from the communication I / F unit 31 to the main apparatus 1 via the data communication path 30 (step 104).
The main apparatus 1 receives this telephone directory list data via the communication I / F unit 15, confirms the command by the data transfer means 12B, and determines whether the information is used by the function processing means 12A. In this case, since it is not information used by the function processing means 12A, it is transferred to the key telephone 2A of the telephone ID added to the telephone directory list data.
[0047]
As a result, the telephone directory list data is directly transferred from the server 3 to the key telephone 2A via the main device 1 and received by the key telephone 2A. The display management means 22A of the key telephone 2A determines that the phone book list data is from the server 3 from the command of the received data, stores it in the CTI screen memory 26B, and self displays the CTI in the subsequent display processing. Since this is the mode, the telephone directory list data stored in the CTI screen memory 26B is read and displayed on the screen display unit 27. FIG. 12 shows a screen display example of the phone book list data.
[0048]
In the key telephone 2A, the cursor (refer to the white display portion in FIG. 12) is moved by operating the arrow keys (step 105). The operation information generation unit 22B generates operation information indicating an arrow key operation in the CTI mode corresponding to these operations, and transmits the operation information to the main apparatus 1 (step 106). The data transfer unit 12B of the main apparatus 1 determines that these pieces of information are not used by the function processing unit 12A based on the received commands of the operation information, and transfers them to the server 3.
[0049]
As a result, the operation information is directly transferred from the key telephone 2 </ b> A to the server 3 via the main device 1. Then, the telephone-corresponding means 32A of the server 3 receives the operation information from the key telephone 2A, and the destination information selected by the cursor of the key telephone 2A based on the contents of the operation is sequentially updated. Further, the updated contents are retransmitted to the key telephone 2, and the telephone directory list data with the cursor moved is displayed on the screen display unit 27 of the key telephone 2A as described above.
In the key telephone 2A, when the call destination is determined by pressing the enter key (step 107), the operation information generating unit 22B generates operation information indicating the enter key operation in the CTI mode, and sends it to the main apparatus 1. (Step 108).
[0050]
The data transfer means 12B of the main apparatus 1 transfers this operation information to the server 3 because it is not information used by the function processing means 12A. In the telephone corresponding means 32A of the server 3, since the received operation information indicates the confirmation key operation, the telephone number of the other party selected at the time of the key telephone 2A is read from the database, and the telephone number is set as the destination. The external line transmission request including the telephone ID of the key telephone 2A is transmitted to the main apparatus 1 (step 109).
[0051]
In the main device 1, an external line transmission request from the server 3 is received, and the function processing means 12A transmits a TEL mode instruction to the key telephone 2A designated by the request (step 110), and connects a call path (step 110). 111). Thereby, at time T2, the key telephone 2A is switched from the CTI mode to the TEL mode, and the call path between the main apparatus 1 and the key telephone 2A is connected. Further, display data indicating that the outside line is being transmitted, which is received from the main apparatus 1 and stored in the TEL screen memory 26A prior to the TEL mode instruction, is displayed on the screen display unit 27.
[0052]
Thereafter, the function processing means 12A controls the external line I / F unit 11 as an external line transmission operation to capture any external line that can be transmitted from the telephone line 10 (step 112), and makes a call with the key telephone 2A. In addition to connecting to the path, the server 3 is notified of the connection confirmation that the call path has been connected (step 113). Then, a dial signal indicating the destination telephone number is sent to the telephone line 10 (step 114).
[0053]
In this way, in response to the operation information indicating confirmation of the other party from the key telephone 2A, the telephone corresponding means 32A of the server 3 transmits an external line transmission request to the main apparatus 1, and the function processing means 12A of the main apparatus 1 Since the key telephone 2A is returned to the TEL mode and the call path with the main apparatus 1 is connected, the outside line is transmitted using the telephone line 10, so that information processing is performed for each key telephone as in the conventional system. There is no need to install a terminal or a means for converting information held in the information processing terminal and distributing it to the key telephone, and the abundant information stored in the information processing terminal without increasing the scale of the system configuration Various services using various information.
In addition, since the outside line is transmitted using the telephone line 10 after connecting the call path between the key telephone 2A and the main apparatus 1, complicated control in the main apparatus 1 and special operation on the key telephone 2A are possible. It becomes unnecessary.
[0054]
Next, another example of the telephone directory transmission operation will be described with reference to FIG. FIG. 13 is a sequence diagram showing another example of the telephone directory transmission operation for transmitting from the key telephone using the database of the server.
In FIG. 11 described above, the case where the outside line is transmitted using the telephone line 10 after connecting the call path between the main apparatus 1 and the key telephone 2A has been described. A case will be described in which a call path is connected at the time when confirmation is made.
[0055]
The processing operation from sending the phone book list data from the server 3 to displaying it on the key telephone 2A and confirming the desired destination is the same as in FIG. In the telephone corresponding means 32A of the server 3, since the received operation information indicates the confirmation key operation, the telephone number of the other party selected at the time of the key telephone 2A is read from the database, and the telephone number is set as the destination. The external line transmission request including the telephone ID of the key telephone 2A is transmitted to the main apparatus 1 (step 109).
[0056]
The function processing means 12A of the main apparatus 1 determines whether or not an outside line can be transmitted from the telephone line 10 (step 120), and if it can make a call, the telephone line 10 is captured (step 121), and the button specified in the request A TEL mode instruction is transmitted to the telephone 2A (step 122), and a call path is connected (step 123). Thereby, at time T3, the key telephone 2A is switched from the CTI mode to the TEL mode, and the call path between the main apparatus 1 and the key telephone 2A is connected. Then, the function processing means 12A notifies the server 3 that the call path has been connected by connection confirmation (step 124).
[0057]
In response to this, the telephone corresponding means 32A of the server 3 generates display information indicating "calling" based on the connection confirmation and transmits it to the key telephone 2A (step 125), whereby the screen of the key telephone 2A is displayed. The display unit 27 displays that “calling”.
The function processing means 12A sends a dial signal indicating the destination telephone number to the captured telephone line 10 (step 126).
[0058]
When the outside line cannot be transmitted in step 120, the reason is notified to the server 3 by the connection confirmation (step 127). In response to this, the telephone corresponding means 32A of the server 3 generates display information indicating the reason why the call cannot be made based on the connection confirmation and transmits it to the key telephone 2A (step 128), whereby the key telephone 2A. The reason why the call cannot be made is displayed on the screen display unit 27.
[0059]
As described above, since the call path is connected when it is confirmed that the call can be made from the telephone line 10, the key telephone 2 </ b> A enters a call state only when the outside line can be sent. Accordingly, when the outside line cannot be transmitted, the call state is not shifted, and the subsequent operation such as disconnection of the call path becomes unnecessary. Further, when there is no free outside line and the telephone line cannot be captured, the server 3 can be easily performed without performing unnecessary processing such as disconnection of the call path when performing subsequent re-transmission control.
[0060]
Next, another example of the telephone directory transmission operation will be described with reference to FIG. FIG. 14 is a sequence diagram showing another example of the telephone directory transmission operation for transmitting from the key telephone using the database of the server.
In FIG. 11 described above, a case has been described in which a call path between the main apparatus 1 and the key telephone 2A is connected, and then an outside line is transmitted using the telephone line 10, but here, after calling from the telephone line 10, a call is made. A case where a call path is connected when the start is confirmed will be described.
[0061]
The processing operations from sending the phone book list data from the server 3 to displaying it on the key telephone 2A and determining the desired destination are the same as in FIG. In the telephone corresponding means 32A of the server 3, since the received operation information indicates the confirmation key operation, the telephone number of the other party selected at the time of the key telephone 2A is read from the database, and the telephone number is set as the destination. The external line transmission request including the telephone ID of the key telephone 2A is transmitted to the main apparatus 1 (step 109).
[0062]
The function processing means 12A of the main apparatus 1 determines whether or not an external line can be transmitted from the telephone line 10 (step 120). If the telephone line 10 can be transmitted, the telephone line 10 is captured (step 121), and the destination telephone number is dialed out. (Step 130). Thereafter, when a ringback tone (RBT) indicating a ringing or a ringing message is detected from the telephone line 10 and it is confirmed that the ringing is started (step 131), a TEL mode instruction is transmitted to the key telephone 2A. Then (step 132), the call path is connected (step 133).
[0063]
Thereby, at time T4, the key telephone 2A is switched from the CTI mode to the TEL mode, and the call path between the main apparatus 1 and the key telephone 2A is connected. Then, the function processing means 12A notifies the server 3 that the call path has been connected (step 134). In response to this, the telephone corresponding means 32A of the server 3 generates display information indicating "calling" based on the connection confirmation and transmits it to the key telephone 2A (step 135), whereby the screen of the key telephone 2A is displayed. The display unit 27 displays that “calling”.
[0064]
If a busy tone (BT) or busy message is detected instead of being called (step 136), the server 3 is notified of this by connection confirmation (step 137). In response to this, the telephone corresponding means 12A of the server 3 generates display information indicating “busy” on the basis of the connection confirmation and transmits it to the key telephone 2A (step 138). The screen display unit 27 displays that the other party is busy.
[0065]
As described above, since the call path is connected when it is confirmed that the call is started, the key telephone 2A enters the call state only when the call state is set. Therefore, even if the outside line can be transmitted, when the other party is busy, the call state is not changed, and the subsequent operation such as disconnection of the call path becomes unnecessary. Further, when performing subsequent retransmission control, it can be easily performed from the server 3 without performing useless processing such as disconnection of a call path. In step 131, the other party's response may be confirmed instead of being called. In this case, only when the other party answers, the call state is entered. Operations such as path disconnection are not required.
[0066]
