Description

  The present invention relates to a mobile radio system such as PHS (Personal Handy-phone System) as an extension telephone of a small-sized telephone device such as a button telephone device controlled by CTI (Computer Telephone Integration) or a private telephone exchange device. The present invention relates to a computer-controlled telephone exchange system that uses a portable telephone and controls a telephone exchange function using a personal computer.

  As a conventional CTI control method, for example, there is a CTI system presented in Patent Document 1 below. In the proposed CTI system, for example, as shown in FIG. 12, a private branch exchange (hereinafter abbreviated as PBX) 110 and a plurality of extension telephones 101-A and 101-B connected to the PBX 110 , A CTI server 120 for comprehensively controlling the PBX 110 and personal computer (hereinafter abbreviated as PC) terminals 130-A and 130-B installed in association with the extension telephones 101-A and 101-B, respectively. Provided. The PBX 110 is connected to the CTI server 120 and notifies the state change of the extension telephones 101-A and 101-B.

  The CTI server 120 is connected to the PC terminals 130-A and 130-B via a LAN (Local Area Network) 140 to exchange information. The CTI server 120 stores in the PC address / extension number correspondence table 122 a pair of the extension number of the extension telephone and the PC address installed in association with the extension telephone at the time of CTI operation. Therefore, the PC terminals 130-A and 130-B can take in the status of the corresponding extension telephones 101-A and 101-B from the CTI event table 121 and display them on the screen. be able to.

  On the PC terminal side, there is an advantage that a large amount of information can be instantly taken out and responded to on the screen, for example, related information of a customer or the like that makes a call with an extension telephone is taken out. Furthermore, various requests to the PBX can be immediately input from the keyboard of the PC terminal instead of a simple input button of the extension telephone. Therefore, computer control over the telephone exchange function is expanding its use.

  However, even in private branch exchanges, portable telephones have become popular as extension telephones, particularly in small telephone apparatuses such as button telephone apparatuses, and recently, digital cordless telephone systems using a small number of radio channels have been adopted. .

  However, since a small number of radio channels are transmitted from the telephone main unit constituting the small-scale telephone apparatus via the radio base station (CS), it is more portable than an extension telephone directly connected to the telephone main apparatus by wire. Setting time for line connection to phone is long. Furthermore, when the number of portable telephones is large with respect to a small number of radio channels, there are many opportunities to make a call because the call channel is insufficient.

JP 2001-119735 A

  The problem to be solved is that in a telephone device using a wireless channel, when a mobile phone starts communication, not only does it take time to search for and secure a usable wireless channel, but also a wireless channel cannot be secured. There are many opportunities for communication.

In the CTI control method according to the present invention, when the CTI application and the PHS perform CTI cooperation, the first processing request including any of a call request , a proxy response request, and a park hold response request in the PHS from the CTI application is performed. When this occurs, the telephone main unit accommodating the extension is made to search and secure a radio channel with the PHS over a predetermined time in preference to the other second processing request, and the first processing request is requested the PHS extension in to call back, by those the PHS extension terminal answers, using the radio channel which has been reserved in the callback is characterized by performing the originating automatically.

Also, the CTI control system according to the present invention increases the probability of securing a radio channel in the telephone device as much as possible when the portable telephone starts communication, so that the personal computer associated with the portable telephone is connected to the telephone main device. For example, when a first processing request such as a call request , a proxy response request , or a park hold response request is sent, the telephone main unit receives the first processing request when receiving the first processing request. If the extension telephone that issued the processing request is a portable telephone, the wireless telephone with the portable telephone is searched and secured with a predetermined time prior to the other second processing request and called back. The main feature is that the communication channel is automatically completed by using the radio channel secured at the time of callback in response to the above.

  Specifically, a telephone main apparatus that accommodates and interconnects a plurality of extension telephones, on the one hand, a portable telephone as the extension telephone is connected via a wireless channel, and on the other hand, the telephone main apparatus and a communication line are connected. And at least one personal computer associated with each of the extension telephones, on the other hand, connected to the telephone main unit to receive notification of a change in the state of the extension telephone in the telephone main unit and A CTI server that sends a request received from a personal computer, receives a request to the corresponding extension telephone connected to the personal computer over the network, and sends information received from the telephone main unit to the corresponding personal computer; is there.

  Here, when the CTI server receives a communication start request from the personal computer associated with the mobile phone, the CTI server sends the request to the telephone main unit together with the associated mobile phone information. .

  In the CTI control system of the present invention, when a request received by the CTI control relates to a connection from a mobile phone, the radio channel with the mobile phone is searched and secured in preference to other processing requests. For this reason, when a callback is made to the mobile phone, an extra waiting time for other request processing that has been received can be deleted, so that a callback can be made to the mobile phone to be called back in the shortest processing time. There is an advantage.

The present invention is a CTI (Computer Telephone Integration) control system, which increases the probability of securing a radio channel in a telephone main unit when a mobile phone starts communication such as a call origination, proxy response, or park hold response. The goal of improving as much as possible was realized. That is, when a predetermined processing request is sent from a personal computer (hereinafter abbreviated as a PC) to the telephone main unit, the main processing unit that receives the processing request is a portable telephone. by confirming that, it calls back to search reserving radio channel with priority to other processing requests the portable telephone with a predetermined time limit, its time of call back by the response of the mobile phone The communication channel is automatically established using the reserved radio channel.

  A first embodiment of the present invention will be described with reference to FIG.

  FIG. 1 is an explanatory diagram showing an embodiment of a block configuration in the CTI control system of the present invention. The CTI control system shown in the figure is for CTI control of a button telephone apparatus that accommodates a plurality of multifunction telephones 1 and a plurality of PHS telephones 2 as extension telephones in the telephone main apparatus 10. As the CTI control unit, the CTI server 20 and the plurality of PC terminals 30 are connected to the LAN 40 together with the telephone main device 10 to operate in cooperation. That is, the CTI server 20 has a CTI control application installed and its operation is controlled by a driver. The PC terminal 30 has a CTI application installed and its operation is controlled by a driver. These controls are based on TCP / IP (Transmission Control Protocol / Internet Protocol).

  The telephone main device 10 connects an external line, a base station (CS) 10-1, and the multi-function telephone 1 to an internal switching network via each port. The external line is, for example, an office line connected to a telephone office or a dedicated line. The base station (CS) 10-1 is a standard for a digital cordless telephone system in Japan, and is a PHS (Personal Handy-phone System) compiled as a standard (RCR-STD-28) of the Radio Industries Association (ARIB). It is a base station. The base station (CS) 10-1 is connected to the PHS telephone 2, which is a personal portable telephone for which a connection request has been made, through a wireless channel, and the other is connected to the telephone main device 10 through a wired channel.

  The telephone main device 10 includes a state change notification unit 11, a call control unit 12, and a CS control unit 13. The state change notification unit 11 notifies the CTI server 20 of the state change of the telephone main device 10 via the LAN 40. The call control unit 12 includes, for example, an out-of-service timer that detects power outage or out-of-communication service for the PHS telephone 2 that uses a radio channel, a response waiting timer that detects no response to a call, and the like. Control call processing for functions. Furthermore, when the call control unit 12 receives a communication start request from the PHS telephone 2 from the PC terminal 30, the call control unit 12 controls the CS control unit 13 to give priority to other processing requests for the corresponding PHS telephone 2. Search and secure the wireless channel. The CS control unit 13 grasps the position of the PHS telephone 2 via the base station 10-1 and controls call connection to the PHS telephone 2. In particular, the CS control unit 13 cooperates with the control of the call control unit 12 when a communication start request from the PHS telephone 2 is received from the PC terminal 30.

  Here, PHS will be described with reference to FIGS. 2 and 3 together.

  The base station (CS) 10-1 and the PHS telephone 2 of the mobile terminal employ a time division multiple access and time division bidirectional multiplexing (TDMA-TDD) system. As shown, there are 4 slots each for transmission and reception, each slot for 625 microseconds, and therefore one frame length is set to 5 milliseconds. Also, since one of the four slots for transmission and reception is a control slot, the number of PHS telephones 1 to which one base station (CS) 10-1 can be connected is limited to three.

  The telephone main device 10 accommodates a multifunction telephone 1 that is fixed in position and a PHS telephone 2 that can be moved cordlessly as extension telephones. These extension telephones have a minimum function as a telephone. The telephone main device 10 changes the state of the external line and the internal line according to the processing request and the response transmitted / received via the external line and the internal line, and stores the state.

  The CTI-controlled telephone main unit 10 is connected to the CTI server 20 and notifies the CTI server 20 of the status of the external line and the extension. When receiving a processing request from the CTI server 20 in addition to the processing described above, In accordance with the request, the state of the external line and the internal line is changed, and the state change is stored and notified to the CTI server 20 by the state change notification unit 11. Further, the telephone main device 10 starts communication such as a call request, a proxy response request, or a park hold response request from the CTI server 20 by the PHS priority selection function that is a feature of the present invention of the CS control unit 13 described above. When there is a request, the target extension telephone is confirmed by the PHS priority selection function.

  On the other hand, the CTI server 20 includes a CTI event table 21, a call control information table 22, a storage unit 23, and a CTI control unit 24.

  FIG. 4 shows an example of the CTI event table 21 and FIG. 5 shows an example of the call control information table 22.

  At startup, the CTI server 20 requests the telephone main device 10 for information including the extension number of the extension telephone connected to the telephone main device 10, the terminal type, key information, and the information on the accommodated external line. Accordingly, the requested information is returned from the telephone main apparatus 10 to the CTI server 20. The CTI event table 21 updates and holds the received information. Accordingly, the state change of the external line and the internal line in the telephone main apparatus 10 is held in the CTI event table 21 by event notification each time. This content can be taken out at any time by the PC terminal 30. Therefore, when receiving a request from the PC terminal 30, the CTI server 20 can pass usable extension and outside line information to the PC terminal 30.

  The PC terminal 30 includes a telephone number table 31 and a PC control unit 32. The telephone number table 31 is a telephone directory created by a user, and may be provided in an external storage device or in a CTI server. The PC control unit 32 has a CTI application and its driver.

  The CTI application of each PC terminal 30 selects the number of the extension telephone to be linked from available lines and notifies the CTI server 20 to create a call control information table 22 indicating the correspondence between the PC address and the extension number. By selecting and fixing the correspondence to be linked, an event is notified from the CTI event table 21 to the CTI application of each PC terminal 30 every time the state of the extension telephone changes. Accordingly, each PC terminal 30 can request the CTI server 20 to start communication with the corresponding extension telephone, such as calling and holding response.

  In FIG. 5, in order to effectively achieve the object of the present invention, the call control information table 22 is intended only for the PHS telephone 2 intended for cordless telephones, but includes the multi-function telephone 1 and includes all extension telephones. You may make it a target. One PC terminal may support a plurality of extension telephones.

  The CTI server 20 is connected to the PC terminal 30 via the LAN 40. Each PC terminal 30 is input by a user as a keyboard as an input unit, a display screen as an output unit, a driver as a control unit, and an area in which various programs for CTI application and other telephone functions are installed in a storage unit It includes a memory area for information, a temporary memory area for processor operation, and the like. For example, the installed CTI application may make a communication start request by simply clicking on a destination telephone number from a telephone directory displayed on the screen.

  Next, an operation procedure in which the PC terminal 30-A and the CTI server 20 specify the destination telephone number 101 and request the start of communication will be described with reference to FIGS. The PC terminal 30-A corresponds to the extension PHS telephone 2-A based on the call control information table 22, and both are used by the same user.

  First, the user can retrieve the contents of the CTI event table 21 on the screen of the PC terminal 30 -A and check the extension telephone state of the telephone main device 10. Accordingly, the user inputs a communication start request specifying the destination extension number 101 by clicking the extension number 101 on the display screen of the PC terminal 3-A.

  Accordingly, the PC terminal 30-A accepts a communication start request designating the destination extension number 101 by a user's click input (step S1), so the CIT application accepts the “communication designating the destination extension number 101” to the driver. Request "start". Since the driver holds the CTI server 20 and the TCP board number, the driver transmits a “communication start request specifying the destination extension number 101” to the CTI server 20 via the LAN 40 (step S2).

  In the CTI server 20, the driver receives a communication start request specifying the destination extension number 101 from the PC terminal 30-A (step S3) and passes it to the CTI control application. The CTI control application searches the call control information table 22 for the extension number 201 and the port number 257 given to the PHS telephone 2-A controlled by the PC terminal from the requesting PC terminal name “3-A” (procedure) S4) to determine the request source. Therefore, in the CTI server 20, the CTI control application passes the connection from the port number 257 of the caller extension number 201 to the designated destination extension number 101 to the driver as a communication start request. Accordingly, the driver transmits this communication start request to the IP address of the telephone main device 10 via the LAN 40 (step S5).

  Next, an operation procedure in which the telephone main apparatus 10 designates the destination telephone number 101 and requests the start of communication will be described with reference to FIGS. 6 to 7 together with FIGS.

  When the telephone main apparatus 10 accepts a communication start request from the port number 257 of the caller extension number 201 to the designated destination extension number 101 from the CTI server 20 (step S6), it returns the acceptance to the CTI server 20. At the same time, the PHS priority selection function of the call control unit 12 checks the terminal type as to whether the calling terminal is a PHS terminal (step S7).

  In this step S7, since the caller extension number 201 is the PHS telephone 2-A (step S8 is YES), the telephone main unit 10 starts a callback process to the PHS telephone 2-A and the number 257. The measurement of the out-of-service timer is started (step S9). That is, the telephone main apparatus 10 searches for a radio channel to the PHS telephone 2-A via the base station (CS) 10-1 and waits for its confirmation (YES in step S10). This is because if the wireless channel cannot be determined because the procedure S10 is “NO” and the PHS telephone 2-A is out of the communication range or is in the power-off state, the wireless channel is not reached when the out-of-range timer is not reached (NO in step S11). It is confirmed that “YES” in step S10 is realized.

  The telephone main device 10 knows that the call request is from the PHS telephone 2-A, and the procedure S10 determined by searching the radio CH via the base station (CS) 10-1 in preference to other processing requests is “ In the case of “YES”, the timer is initialized and the callback to the PHS telephone 2-A is started (step S12), and then the response waiting timer is started (step S13). Since the user usually holds the corresponding PHS telephone 2-A when operating the PC terminal 3-A, the user can immediately respond with the PHS telephone 2-A. However, if there is no response to the callback (NO in step S14), the telephone main apparatus 10 waits for a response to the callback while the response waiting timer has not yet reached (NO in step S15).

  When the procedure S14 is “YES” and the response from the PHS telephone 2-A is received, the telephone main apparatus 10 initializes the timer (procedure S16) and secures the wireless CH for the call. Then, the multi-function telephone 1-A having the extension number 101 designated as the destination is called by the call signal (step S17). At the same time, the telephone main device 10 notifies the corresponding PC terminal 3-A of “calling start” via the CTI server 20 (step S18).

  Thereafter, when the telephone main device 10 receives a response from the multi-function telephone 1-A, the telephone main apparatus 10 controls the internal switching network using the previously secured radio channel, and the PHS telephone 2-A and the multi-function telephone 1- A normal operation of forming a speech path by connecting the line to A is automatically performed.

  If step S8 is “NO” and the terminal is not a PHS terminal, a normal communication start processing procedure (step S20) is executed.

  When the procedure S11 is “NO” and the time limit of the out-of-service timer is reached, or when the procedure S15 is “NO” and the response waiting timer is reached, the telephone main device 10 initializes the timer (step S21), and the CTI server 20 is notified to the PC terminal 3-A corresponding to the PHS telephone 2-A of the caller (step S22).

  The state change due to the above-described operation is notified from the telephone main apparatus 10 to the CTI server 20, and predetermined matters are recorded in the CTI event table 21.

  Next, the flow described above will be described again using the sequence chart of FIG.

  First, the user of the PC terminal 3-A retrieves the contents of the CTI event table 21 obtained from the telephone main apparatus 10 on the display screen, confirms the extension telephone state of the key telephone apparatus, and transmits the CTI server from the PC terminal 3-A. 20 specifies the connection extension number 101 and inputs a communication start request (step S31).

  The CTI server 20 determines that the communication start request from the PC terminal 3-A is a request from the extension number 201 of the corresponding PHS telephone 2-A based on the call control information table 22. Therefore, the CTI server 20 requests the telephone main apparatus 10 to connect from the extension number 201 to the extension number 101 (step S32).

  The telephone main device 10 knows that the connection request is from the PHS telephone 2-A by the PHS priority selection function of the call control unit 12, and prioritizes other processing requests through the base station (CS) 10-1. The wireless CH is searched and confirmed, and the PHS telephone 2-A is called back through the confirmed wireless CH (step S33). The user can immediately respond to this callback by the PHS telephone 2-A (step S34).

  When the telephone main device 10 receives a response from the PHS telephone 2-A, the telephone main device 10 secures the wireless CH for a call (step S35), and is given the extension number 101 designated as the connection destination. The port of the telephone 1-A is selected for line connection (step S36). Next, the telephone main unit 10 controls the internal switching network, and automatically connects the ports of the PHS telephone 1-A and the multi-function telephone 2-C (step S37) to automatically form a communication path. Calls and communications are possible. In the above step S36, in the case of a call request, the called party may be via an external line, so the line selection to the connection destination is made.

  The communication start request described above includes a call, a proxy response, a park hold response, and the like.

  Since such an embodiment is adopted, the telephone main unit of the key telephone apparatus can call back the PHS telephone by establishing a radio channel in preference to other processes. Therefore, the user can obtain a communication start ready state in the shortest time without waiting for other processing only with the required time for setting the radio channel. Since the user can know the line status of the key telephone apparatus at the PC terminal, even the PHS telephone can be connected to the other party without any extra waiting at the start of communication.

  Although the PHS telephone is described here, as described above, the present invention can be applied not only to the digital cordless telephone system but also to all mobile communication systems using a wireless network.

  Next, as a second embodiment of the present invention, a case where a PHS telephone makes a call request will be described with reference to FIGS. 1 to 5 in FIG.

  In FIG. 9, the communication start request described in FIG. 8 is a call request, and the connection destination telephone is a called telephone. Therefore, the second embodiment describes a communication start procedure when a user makes a call from the PHS telephone 2-A having the extension number 201 using the PC terminal 3-A. The PC terminal 3-A corresponds to the PHS telephone 2-A according to the call control information table 22, and the same user uses both the PC terminal 3-A and the PHS telephone 2-A.

  First, the user of the PC terminal 3-A retrieves the contents of the CTI event table 21 obtained from the telephone main apparatus 10 on the display screen, confirms the extension telephone state of the key telephone apparatus, and transmits the CTI server from the PC terminal 3-A. 20 designates the called extension number 101 and inputs a call request (step S41).

  The CTI server 20 determines that the call request from the PC terminal 3-A is a request from the extension number 201 of the corresponding PHS telephone 2-A based on the call control information table 22. Therefore, the CTI server 20 requests the telephone main apparatus 10 to establish a communication path connection from the caller extension number 201 to the called extension number 101 (step S42).

  The telephone main device 10 knows that the call request is from the PHS telephone 2-A by the PHS priority selection function of the call control unit 12, and prioritizes other processing requests via the base station (CS) 10-1. Two wireless CHs are searched and confirmed, and the PHS telephone 2-A is called back via the confirmed wireless CH (step S43). The user can immediately respond to this callback by the PHS telephone 2-A (step S44).

  When the telephone main apparatus 10 receives the response from the PHS telephone 1-A, the telephone main apparatus 10 secures the wireless CH for the call (step S45) and has the extension number 101 designated as the called party. -A is called by a call signal (step S46). The telephone main device 10 receives the response of the multifunction telephone 1-A (step S47), controls the internal switching network, and connects the line between the PHS telephone 2-A and the multifunction telephone 1-A (procedure S48), a communication path is formed to enable communication and communication.

  Next, as a third embodiment of the present invention, a case where a PHS telephone makes a proxy response request will be described with reference to FIGS. 1 to 5 in FIG.

  In FIG. 10, the communication start request described with reference to FIG. 8 is a proxy response request, and the connected telephone is a called telephone that receives a call but cannot answer. Therefore, the third embodiment describes a procedure in which the user performs a proxy response to the incoming call to the multi-function telephone 1-A, which is the called telephone, using the PC terminal 3-A and the PHS telephone 2-A having the extension number 201. ing. The PC terminal 3-A corresponds to the PHS telephone 2-A according to the call control information table 22, and the same user uses both the PC terminal 3-A and the PHS telephone 2-A.

  First, the multi-function telephone 1-A has an incoming call and the bell is ringing by a ringing signal (step S50).

  The user of the PC terminal 3-A retrieves the contents of the CTI event table 21 obtained from the telephone main apparatus 10 on the display screen, confirms the extension telephone state of the key telephone apparatus, and transfers from the PC terminal 3-A to the CTI server 20. A proxy response request (procedure S51) is input by designating the extension number 101 in which the bell is ringing.

  The CTI server 20 determines that the proxy response request from the PC terminal 3-A is a request from the extension number 201 of the corresponding PHS telephone 2-A based on the call control information table 22. Accordingly, the CTI server 20 requests the telephone main apparatus 10 to make a proxy response instead of the caller extension number 201 instead of the callee extension number 101 (step S52).

  The telephone main device 10 knows that the proxy response request is from the PHS telephone 2-A by the PHS priority selection function of the call control unit 12, and prioritizes other processing requests via the base station (CS) 10-1. One wireless CH is searched and confirmed, and the PHS telephone 2-A is called back through the confirmed wireless CH (step S53). The user can immediately respond to this callback by the PHS telephone 2-A (step S54).

  When the telephone main device 10 receives the response from the PHS telephone 2-A, the telephone main device 10 secures the wireless CH for a call as described above. Further, the telephone main unit 10 controls the internal switching network as a proxy of the multifunction telephone 1-A having the extension number 101 called from a caller not shown, and is indicated as PHS telephone 2-A. A line is connected to a caller that does not exist (procedure S55) to form a speech path, enabling speech and communication.

  Next, as a fourth embodiment of the present invention, a case where a PHS telephone makes a park hold response request will be described with reference to FIGS.

  In FIG. 11, the communication start request described in FIG. 8 is a park hold response request, and the connection destination telephone is an extension telephone that is parked together with a plurality of telephones. Therefore, the fourth embodiment describes a procedure in which the user makes a park hold response to the multifunction telephone 1-A, which is a park hold telephone, by the PHS telephone 2-A having the extension number 201 using the PC terminal 3-A. . The PC terminal 3-A corresponds to the PHS telephone 2-A according to the call control information table 22, and the same user uses both the PC terminal 3-A and the PHS telephone 2-A.

  First, multifunction telephone 1-A is parked with another telephone (step S60).

  The user of the PC terminal 3-A retrieves the contents of the CTI event table 21 obtained from the telephone main apparatus 10 on the display screen, confirms the extension telephone state of the key telephone apparatus, and transfers from the PC terminal 3-A to the CTI server 20. A park hold response request (step S61) is input by designating the extension number 101 that is parked.

  The CTI server 20 determines that the park hold response request from the PC terminal 3-A is a request from the extension number 201 of the corresponding PHS telephone 2-A based on the call control information table 22. Accordingly, the CTI server 20 requests the telephone main apparatus 10 to make a park hold response from the caller extension number 201 to the partner extension number 101 (step S62).

  The telephone main device 10 knows that the park hold response request is received from the PHS telephone 2-A by the PHS priority selection function of the call control unit 12. Accordingly, the telephone main apparatus 10 searches and determines one wireless CH via the base station (CS) 10-1 in preference to other processing requests, and then determines the PHS telephone 2-A via the determined wireless CH.
