Description

  The present invention relates to outgoing / incoming control in a communication network.

  In recent years, a communication system including a PBX (private branch exchange) that uses a public mobile terminal as an extension telephone has become widespread.

  An example of a configuration that uses both a public mobile terminal that uses a connection service of a mobile carrier and a PBX is shown below.

  In FIG. 1, PBX 110 is a private branch exchange, EX-TEL (120, 122) is a PBX extension telephone, BS (112, 114) is a private base station for using private PHS, PSTN 106 is a fixed public network, and TEL 108 is Subscriber telephone, P-PHS 104 is a public PHS network, CS 102 is a public PHS base station, PS (130, 132) is a public PHS (connection with CS), and private PHS (connection with BS) is possible It is a PHS terminal.

  In FIG. 1, the PS 130 is used as a public PHS terminal when used outside the office, and can be used as an extension terminal of the PBX 110 in the private PHS mode when used in an office.

  FIG. 2 shows a case where a mobile terminal such as 3G is used as a public mobile terminal. MT 210 is a mobile terminal, MVN 230 is a mobile phone network, and RFE 220 is an antenna facility.

  In FIG. 2, the portable terminal MVN230 is used outside the office, and the office PHS terminal PS130 is used as an extension inside the office.

  However, in both FIG. 1 and FIG. 2, it is necessary to prepare equipment (BS112, BS114) such as a base station of a private PHS. In the example in FIG. 2, two separate terminals (PS 130 and MT 210) are required inside and outside the office.

  There is a technique in which a PBX is arranged between a public PHS network and a public base station, and a connection related to a public PHS number registered in the PBX is an extension connection (see, for example, Patent Document 1).

  Also, in the PBX that accommodates the PHS base station, a plurality of extension numbers are assigned to the same PS, or the same extension number is assigned to a plurality of PSs, and each of the PS and PBX is assigned using dedicated PS identification information. Thus, there is a technology for performing connection and status management based on the PS identification information (see, for example, Patent Document 2).

  In the following embodiments of the present invention, a PBX (private branch exchange) will be mainly described as an example of an outgoing / incoming control device, but the PBX in the various embodiments may be present in a network such as the Internet. Good. Needless to say, the target line is not limited to wireless communication or wired telephone communication, but can be used for Internet telephones and other communications using the Internet. The various embodiments of the present invention are not intended only for voice calls, and may be used for communication of images and other contents. In addition, the present invention is not limited to the protocol related to the communication of the embodiment exemplified in this specification. It should also be noted that the various embodiments of the present invention need not be physically located in a particular location or machine, but may be implemented in a distributed form on the network.

  FIG. 3 shows an example in which a public mobile terminal is used even in an office.

  In the case of FIG. 3, the PBX 110 is registered in advance in the variable absent forwarding table 310 using the variable absent forwarding from the extension to the PS. For this reason, the extension number (DN 312) for performing variable unattended transfer and the subscriber number (TRS 314) of the public PHS of the variable unattended transfer destination of this extension number are registered in the variable unattended transfer table 310.

  In the call management table 320, a call management number (CDN 322) is assigned when a call is generated, and information related to the call is stored in association with the CDN 322. FIG. 3 shows an example in which information on the call origination side connection destination (ORG 324) and the call termination side connection destination (TRM 326) is included in the call management table.

  FIG. 4 shows an example of transmission from the PS 130 in the configuration of FIG.

  In FIG. 4, the PS 130 indicates the line number (0411111222) of the fixed network of the PBX 110 as the called party number (A :) of the call setup message transmitted to the public PHS base station (CS 102), and the connection destination number after receiving the PBX 110. Set the destination subaddress (SA :) and make a call. In this example, since the call originates from the PS corresponding to the extension telephone 3001, (07011113001) is set in the calling number (OA).

  The user of the PS 130 uses the PS 130 to register, for example, the line number of the fixed network of the PBX 110 in advance in the telephone directory, etc., and after reading this, add “*” indicating the called sub address and information to be put on the called sub address. The call setting message may be transmitted by an operation such as making a call.

  The calling number is written in the PS 130 at the time of the line contract and is automatically set.

  As for the information of this call setting 402a, the PBX 110 receives the call setting 402b via the PSTN 106 and processes the information of the called subaddress, so that the local line transmission is determined at the leading “0”, and the subsequent address becomes the called address. The call is transmitted to the PSTN 106 as a call setting 402c, and the connection destination (TEL) responds to complete the connection between the PS 130 and the TEL 108.

  Details of FIG. 4 are as follows. In addition, the part described as P-PHS / PSTN means passing through P-PHS and PSTN. This is the same in other drawings. Call setting acceptance (CALL PROC 404a, 404b, 404c) is returned for the call setting (SETUP 402a, 402b, 402c), respectively. At this time, the local line transmission connection 401 is made from the PBX 110 to the PSTN 106. From the PSTN 106, an incoming signal 408 is sent to the TEL 108, and a call (ALERT 406c, 406b, 406a) is sent to the PS 130. As a result, the ringing tone 410 is sent from the PSTN 106 to the PS 130. When the TEL 108 returns the response 411 to the PSTN 106, a response (CONN 412c, 412b, 412a) is sent to the PS 130. In response to this, a response confirmation (CONN ACK 414b, 414c) is returned and a ringing tone stop 416 is made. Thereafter, the state becomes 418 during a call.

  In this connection, the PBX 110 associates this call with the CDN 332, and as the information of CDN = n, the line number (TRKa) of the call origination-side fixed network line accommodating trunk is set in the ORG 324, and the call termination side is fixed. The line number (TRKb) of the network line accommodating trunk is set in the TRM 326.

  If the information on the destination subaddress received by the PBX 110 is an extension number, it is connected to the extension of the PBX 110.

  When a call is disconnected, a disconnection signal is received from the connection destination of the ORG 324 or the connection destination of the TRM 326. The call management table 320 is referred to, a call being connected is detected, and the connection destination release processing of the ORG 324 and the TRM 326 is performed. I do. As a result, the call is disconnected. At this time, the information of CDN = n is cleared and CDN = n is released.

  Specifically, the disconnection (DISC 420a, 420b, 420c) is transmitted from the PS 130 to the PSTN 106, and the busy tone 424 is transmitted to the TEL 108. Along with this, a release (REL 422a, 422b, 422c) is sent. Then, release completion (REL COMP 426a, 426b, 426c) is sent for release (REL 422a, 422b, 422c) in each section. The TEL 108 becomes free by sending a disconnect 428 to the PSTN 106.

  FIG. 5 shows an example of an incoming call to the PS 130 in the configuration of FIG.

  In FIG. 5, when the subscriber telephone (TEL 108) of the PSTN 106 makes a call with the dial-in number corresponding to the extension telephone 3001 of the PBX 110, the PBX 110 receives this called number from the PSTN 106 and determines that it is an incoming call to the extension telephone 3001. To do. Since the variable absence transfer is registered so that the extension telephone 3001 is transferred to the public PHS number, the call is transmitted to the PS 130 under the public PHS via the PSTN 106. When the PS 130 responds, the connection between the TEL 108 and the PS 130 is completed.

  In detail, the TEL 108 starts the transmission 502 and sends (044222223001) as the dial 504 to the PSTN 106. The PSTN 106 sends the call setup (SETUP 506c, 506b, 506a) to the PS 130. In response to this, call setting acceptance (CALL PROC 508c, 508b, 508a) is returned. At that time, since the variable absent transfer is registered as described above, the PBX 110 sends the number (07011113001) of the PC 130 in the call setup SETUP 506b to perform automatic transfer to the PS 130. Thereafter, a call (ALERT 410 a, 510 b, 510 c) is sent from the PC 130 to the PSTN 106. Then, a ringing tone 512 is sent from the P-PHS 104 to the TEL 108. The PS 130 sends a response (CONN 514a, 514b, 514c) to the PSTN 106, a response confirmation (CONN ACK 516a, 516b, 516c) is returned, and a ringing tone stop 518 is made. Then, it becomes 520 during a call.

  In addition, a cut 521 is made to the PSTN 106 from the TEL 108. Thereafter, the disconnection (DISC 522c, 522b, 522a) is transmitted from the PSTN 106 to the PS 130, and the busy tone 525 is transmitted from the P-PHS 104 to the PS 130. Also, release (REL 542c, 542b) and release completion (REL COMP 542c, 542b) are sent, respectively. Thereafter, release (REL 528) and release completion (REL COMP 530) are exchanged between PS 130 and P-PHS 104.

  Similarly, when a call is made from the extension telephone 2000 to the extension telephone 3001, it is similarly connected to the PS 130 under the public PHS.

  As described above, the CDN 322 numbering in the case of an incoming call to the PS 130 and the processing of the call management table 320 are performed in the same manner as in the case of the outgoing call from the PS 130 described above.

  In the connection between the public mobile terminal and the PBX 110 shown in FIG. 3, since the public mobile terminal is connected via the mobile communication carrier network, the state of the public mobile terminal cannot be managed in the PBX 110. Alternatively, the public mobile terminal cannot transmit information for controlling the call to the PBX 110 during a call of the public mobile terminal. For this reason, additional services of the PBX 110 such as hold / transfer, pickup, and camp-on cannot be used.

  Therefore, regarding the connection between the public mobile terminal and the PBX 110, it is desirable to make the additional service of the PBX 110 available to the public mobile terminal without adding functions of the public mobile terminal and the mobile carrier network.

  FIG. 6 shows the configuration of an embodiment of the present invention.

  In FIG. 6, DN 612 is an extension number, PUBN 614 is a PS 130 public PHS subscriber number, STAT 616 is a PS 130 state, PUG 618 is a pickup group information, and HTG 619 is an extension representative group information. In the STAT 616, the idle state is “0”, but the information is updated every time the state of the PS 130 connected via the fixed line changes. The PUG 618 and the HTG 619 can be configured in the same group as the extension telephone.

  The embodiment of FIG. 6 sets this extension number in the O-PS 638 when the caller is the PS 130 registered in the PS management information in the call management table 630. If the called party is PS 130 registered in the PS management information, this extension number is set in T-PS 639.

  As shown in FIG. 4, when a call originates from the PS 130, the PBX 110 is set to (07011113001) in the SETUP call origin number (O-A), and thus the PS 130 in which PS management information is registered. Judge that there is. Then, the corresponding extension number (3001) is set in the O-PS 638 of the call management table 630, and 1 (during outgoing call) is set in the STAT 616 column of the corresponding extension number in the PS management information 610. An example of the correspondence between values stored in the STAT and states is shown in the correspondence table 620.

  In the case of an incoming call to the PS 130 as shown in FIG. 5, it is determined that the incoming call is a dial-in incoming call from the destination address of the call setup SETUP message received by the PBX 110 to the extension number 3001. Since this extension number 3001 is an extension number registered in the PS management information 610, when there is an incoming call via the fixed network line, it is transferred to 07011113001. At this time, the corresponding extension number (3001) may be set in the T-PS 639 of the call management table 630, and 2 (incoming) may be set in the STAT 616 of the corresponding extension number DN612 of the PS management information 610.

  When the call related to the PS 130 registered in the PS management information 610 is terminated, call disconnection is detected from the connection destination of the ORG 634 or the TRM 636 in the call management table 630. At this time, if the extension number of the PS 130 registered in the PS management information is set in the O-PS 638 or T-PS 639, the connection destination of the corresponding ORG 634 and TRM 636 is released and the correspondence of the PS management information 610 The STAT 616 of the extension number to be changed is changed to 0 (empty).

  In this way, the PBX 110 uses the PS management information 610 or the call management table 630 to update the PS management information 610 whenever a call of the PS 130 registered in the PS management information 610 is generated, changed, or terminated. It can be recognized that it is a registered extension number. Then, the status of the STAT 616 in the PS management information 610 is updated.

  Hereinafter, embodiments of each additional service will be described using the configuration example of FIG.

  FIG. 7 is an embodiment of hold / hold release.

  When the PS 130 is disconnected during a call 702, the PBX 110 may automatically hold the connection partner (701) and send a hold sound 705 to the connection partner.

  That is, when the PBX 110 detects disconnection from the fixed network line (704b), the call management number (CDN 632) can be known from the call management table 630 from the line number of the fixed line accommodating trunk. It is possible to check whether or not the extension number registered in the PS management information 610 is set in the O-PS 638 or T-PS 639 registered in the CDN 632. When an extension number is stored in the O-PS 638 or T-PS 639 corresponding to the disconnection source (ORG 634 or TRM 636) registered in the call management table 630, the connection partner is automatically held for a predetermined time. May be. Then, the status (STAT) of the corresponding extension number in the PS management information 610 is changed to 4 (pending). If no extension number is registered in the O-PS 638 or T-PS 639 corresponding to the disconnection source (ORG 634 or TRM 636) registered in the call management table 630, the call is released without holding. You may do it.

  If there is an incoming call with the same calling number as that of the held PS 130 during this hold, and the special number 16 corresponding to the hold release instruction is set in the destination subaddress of this incoming call information, the hold is released and the original call state is restored. You may perform the process which returns.

  That is, since the calling number included in the SETUP message (712a) is the public PHS number (07011113001) registered in the PS management information 610, the PBX 110 has the extension number (3001) registered in the PS management information 610. It is detected that the PS 130 is outgoing. In addition, it is detected that the hold release special number 16 is set for the destination subaddress. In this case, when the PS management information 610 recognizes that the state of the extension number (3001) is pending (STAT = 4), the call management table 630 causes the O-PS 638 or T-PS 639 to The CDN 632 in which the extension number (3001) is set is detected. Then, the line number of the fixed network line accommodating trunk that has received an incoming call from the PS 130 is set in the ORG 634 or the TRM 636 in which the extension 3001 of the CDN 632 is set, and the STAT 616 corresponding to the extension number in the PS management information 610 is set to 3 ( Change to busy. Then, the path between the PS 130 and the connection partner who was listening to the hold tone is connected.

  Note that, when making a call from the PS 130, the hold release special number 16 may be set as the destination subaddress, for example, in the same procedure as the method of setting the connection destination number as the destination subaddress in FIG.

  When there is no hold release request from the PS 130 during the hold and a timeout occurs, processing may be performed to release the call by sending a busy tone that prompts the other party on hold to disconnect.

  In this case, the STAT 616 corresponding to the extension number in the PS management information 610 is changed to 0 (free).

  If a timeout occurs during the hold, processing such as a call back may be performed.

  Details of FIG. 7 are as follows.

  Assume that the PS 130 and the TEL 108 are busy 702. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description. In the description of the other embodiments, the same pattern will be used.

  The disconnection (DISC 704a, 704b) is sent from the PS 130 to the PBX 110. At subsequent timing 701, the PBX 110 may hold the TEL 106 without releasing the call. For this reason, the hold sound 705 may be sent to the TEL 106. Then, the countdown of the timer T set with a predetermined time may be started (710). On the other hand, between the PS 130 and the PBX 110, release (REL 706a, 706b) and release completion (REL COMP 708a, 708b) may be exchanged to release the call. Thus, after the call is released, the PS 130 can perform other communications.

  Thereafter, when the PS 130 wishes to cancel the hold, the following processing is performed. Call setting (SETUP 702a, 702b) is sent from the PS 130 to the PBX 110. At this time, the PS 130 may set the hold cancellation instruction 16 in the destination subaddress SA. Then, call setting acceptance (CALL PROC 714a, 714b) is returned. The PBX 110 may return a response (CONN 716b, 716a) to the PS 130 that has received the call setup SETUP 706b before the timer times out. Then, a response confirmation CONN ACK 718 is returned. Further, for the TEL 108, the hold sound stop 717 is executed. Then, the PBX 110 resumes the call between the PS 130 and the TEL 108 (during call 720).

  FIG. 8 is an embodiment of transfer.

  The call on hold with the PS 130 is put on hold as in FIG. If there is an incoming call with the same calling number as the PS 130 that was on hold during the hold, and the special number 17 indicating transfer and the transfer destination number are set in the destination subaddress of this incoming call information, the transfer processing may be performed. .

  That is, the PBX 110 calls the transfer destination, changes the STAT 616 of the corresponding extension number of the PS management information 610 to 1 (during outgoing call), and changes the STAT 616 to 3 (during a call) when the transfer destination responds. The transfer process is performed in the same manner as the conventional process.

  Note that, when making a call from the PS 130, the transfer special number 17 and the transfer destination number are set in the destination subaddress as in the method of setting the connection destination number in the destination subaddress in FIG. 4, for example.

  Details of FIG. 8 are as follows.

  Assume that the PS 130 and the TEL 108 are 802 during a call. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description.

  FIG. 7 shows disconnection from the PS 130 (802a, 802b), automatic hold 801, hold sound 804 from the PBX 110 to the TEL 108, release (REL 806a, 806b), timer T countdown 810, release completion (REL COMP 808a, 808b). It is the same as that of description.

  With the above processing, the PS 130 can start processing for a call with the extension telephone 2000 as a transfer destination. First, the call setting (SETUP 812a, 812b) is sent from the PS 130 to the PBX 110. Call setting acceptance (CALL PROC 814a, 814b) is returned respectively. A call (ALERT 810b, 816a) is sent from the PBX 110 to the PS. Then, the incoming call is received from the PBX 110 to the extension telephone 2000 (818). When the extension telephone 2000 returns a response 820 to the PBX 110, the PBX 110 sends a response (CONN 822b, 822a) to the PS 130. A response confirmation CONN ACK 823 is returned to the PBX 110. Then, PS 130 and the extension telephone 2000 become busy 824. Here, the speaker of PS 130 may notify the speaker of extension telephone number 2000 that the TEL 108 call will be transferred. Thereafter, the PS 130 sends a disconnect (DISC 826a, 826b) to the PBX 110. In contrast, release (REL 828a, 828b) and release completion (REL COMP 830a, 830b) are exchanged between PS 130 and PBX 110, respectively. After sending the REL 828b, the PBX 110 executes the hold tone stop 829 for the TEL 108. Thereafter, the PBX 110 starts a call between the extension telephone 2000 and the TEL 108 (during call 840).

  FIG. 9 shows an embodiment in which a call that is received by an extension telephone is picked up from PS 130. Pick-up refers to a process for setting a call by answering a call received by another extension telephone from another extension telephone.

  Extension telephone 2000 and PS 130 (extension telephone 3001) are set to the same pickup group (G1).

  A pickup group may be set for the extension telephone 2000 and other extension telephones. The pickup group may be set by the PUG 618 of the PS management information 610, for example. The incoming call status may be managed in STAT 616. For the management of the extension pickup group, a conventional technique may be used.

  Assume that the subscriber telephone (TEL 108) of the PSTN 106 has made a call with a dial-in number corresponding to the extension telephone 2000, and the extension telephone 2000 is receiving a call. If there is an incoming call from the PSTN 106 in which the public PHS subscriber number (07011113001) corresponding to the extension telephone 3001 is set as the calling party number and the pickup special number 12 is set as the called subaddress, the PBX 110 stops receiving the extension telephone 2000 Then, the TEL 108 and the PS 130 are connected.

  That is, since the PBX 110 has the public PHS number (07011113001) registered in the PS management information 610 set in the calling number (OA) of the SETUP message (SETUP 916b) received from the fixed network line, the PS management information It is detected that the call originates from PS 130 registered in 610. Then, it is detected that the pickup special number 12 is set as the destination subaddress. Therefore, it is confirmed whether the incoming call is in the same pickup group as the pickup group (G1) corresponding to the extension number 3001. Then, it detects that the extension telephone 2000 of the same pickup group is receiving a call. Then, the PS 130 is connected to a fixed network line trunk that is receiving a call via the fixed network line. The extension telephone 2000 that has been processing the incoming call is made free. Then, the STAT 616 of the corresponding extension number (3001) in the PS management information 610 is changed to 3 (during a call).

  Note that, when making a call from PS 130, setting pickup special number 12 as the destination subaddress may be the same as the method of setting the connection destination number as the destination subaddress in FIG. 4, for example.

  Details of FIG. 9 are as follows. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description.

  Assume that a call is received from the TEL 108 to the extension telephone 2000.

  First, the TEL 108 starts a transmission 902 and sends (044222222000) as a dial 904 to the PSTN 106. The PSTN 106 sends a call setup SETUP 906 to the PBX 110. The PBX 110 returns a call setting acceptance CALL PROC 908. An incoming call 910 is made from the PBX 110 to the extension telephone 2000. The PBX 110 sends a call ALERT 912 to the PSTN. Then, a ringing tone 914 is sent from the PBX 110 to the TEL 108.

  In this state, a call has arrived at the extension telephone 2000. The PS 130 sends the call setup (SETUP 916a, 916b) to the PBX 110. At this time, the pickup special number 12 is stored in the destination subaddress. Call setting acceptance (CALL PROC 918a, 918b) is returned respectively. At this point, the PBX 110 executes a pickup process 901. If pick-up is possible, a response (CONN 920b, 920a) is sent to the PS 130, a response confirmation CONN ACK 922 is returned to the PBX 110, and an incoming call stop 924 from the PBX 110 to the extension telephone 2000 is performed. Then, the PBX 110 starts a call between the PS 130 and the TEL 108 (during call 930).

  FIG. 10 shows an embodiment in the case of picking up an incoming call to the PS 130 from the extension telephone 2000 of the PBX 110.

  Similarly to the above, it is assumed that the extension telephone 2000 and the PS 130 (extension 3001) are set to the same pickup group (G1).

  Assume that there is an incoming call from the subscriber telephone TEL 108 of the PSTN 106 to the extension telephone 3001. The PBX 110 calls the PS 130 via the PSTN 106 based on the PS management information 610 and updates the STAT 616 corresponding to the extension telephone 3001 of the PS management information 610 to “2” during the incoming call.

  In this state, when there is a call from the extension telephone 2000 and the pickup special number 12 is dialed, since the extension telephone 3001 (PS 130) in the same pickup group is receiving a call, the incoming call to the PS 130 is stopped and the call to the PS 130 is made. The TEL 108, which is a user, is connected to the extension telephone.

  That is, the PBX 110 is receiving the PS 130 corresponding to the extension telephone 3001 in the same pickup group (G1) as the extension telephone 2000 dialing the pickup special number. This incoming call is detected because the STAT 616 of the corresponding extension number (3001) in the PS management information 610 is 2 (incoming call). Therefore, the extension telephone 2000 is connected to the incoming fixed network line trunk. Then, the call of the fixed network line trunk calling the PS 130 is released.

  Also, the STAT 616 corresponding to the extension telephone 3001 in the PS management information 610 is updated to a free “0”.

  Details of FIG. 10 are as follows. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description.

  Assume that a call is received from TEL 108 to PS 130.

  First, the TEL 108 starts a call 1002 and sends (044222223001) as a dial 1004 to the PSTN 106. The PSTN 106 sends the call setup (SETUP 1006c, 1006b, 1006a) to the PS 130. Call setting acceptance (CALL PROC 1008c, 1008b, 1008a) is returned, respectively. Thereafter, a call (ALERT 1010a, 101b, 1010c) is sent from PS 130 to PSTN 106, and a ringing tone 1012 is sent from P-PHS 104 to TEL 108.

  In this state, a call is received from the TEL 108 to the PS 130. The extension telephone 2000 starts the call 1022 and sends the dial special number 12 to the PBX 110. In the PBX 110, a pickup process 1001 is executed. If it can be picked up, a connection completion 1026 is sent to the extension telephone 2000. The PBX 110 sends a response CONN 1028 to the PSTN 106 and receives a response confirmation 1031. In addition, the PBX 110 sends a release (REL 1030b, 1030a) to the PS 130 in order to release the call with the PS 130. Release complete (REL COMP 1032b, 1032a) is returned, respectively. Then, a call is made between the TEL 108 and the extension telephone 2000 (during call 1040).

  FIG. 11 shows an embodiment in the case where camp-on (waiting) registration is performed from the PS 130 to a busy extension telephone (EX-TEL). Camp-on refers to a function that registers an extension in a call with another party, recalls the registered extension at the end of the call, and enables connection with the other party in the call.

  First, when a call is made from the PS 130 to the extension telephone 2000 that is busy, the call is busy. Therefore, the PS 130 temporarily releases the call and receives the special number 15 indicating the camp-on function and the extension number (2000) for performing the camp-on. A call is made to the PBX 110 with the sub address set.

  When calling from PS 130, the camp-on special number 15 and the extension number (2000) for camp-on are set as the called sub-address, for example, in the same manner as the method of setting the connection destination number as the called sub-address in FIG. There may be.

  Upon receiving this incoming call, the PBX 110 confirms that the extension telephone 2000 is busy and registers camp-on from the extension telephone 3001 corresponding to the calling number to the extension telephone 2000. Then, the STAT 616 of the PS management information 610 of the extension telephone 3001 is updated to “6”. A reception confirmation sound for camp-on registration is transmitted to PS 130. In response, the PS 130 releases the camp-on registration call.

  Thereafter, when the extension telephone 2000 becomes idle, the PBX 110 calls back the PS 130. When the PS 130 responds, the extension telephone 2000 (EX-TEL) is called, and the extension responds, whereby the connection between the PS 130 and the extension telephone 2000 is completed.

  Details of FIG. 11 are as follows. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description.

  Assume that the extension telephone 2000 is busy. First, the call setting (SETUP 1102a, 1102b) is sent from the PS 130 to the PBX 110. Call setting acceptance (CALL PROC 1104a, 1104b) is returned, respectively. Since the extension telephone 2000 is busy, the release completion REL COMP 1106 is sent from the PBX 110 to the P-PHS 104, and the disconnect DISC 1108 is sent to the PS 130. From the PS 130, the release REL 1110 is sent to the P-PHS 104, and the release completion REL COMP 1112 is returned. By this process, the call from the PS 130 is released.

  Processing when PS 130 wishes to camp on is shown below.

  The PS 130 sends the call setup (SETUP 1114a, 1114b) to the PBX 110. At this time, a camp-on special number 15 and an extension number 2000 connected (152000) are set in the destination subaddress. Call setting acceptance (CALL PROC 1116a, 1116b) is returned, respectively. A response (CONN 1118b, 1118a) is sent from the PBX 110 to the PS 130, a camp-on registration process 1101 is executed, and a response confirmation CONN ACK 1120 is returned from the PSTN 106. Thereafter, a camp-on acceptance confirmation sound 1122 is sent from the PBX 110 to the PS 130. The PS 130 sends a disconnect (DISC 1124a, 1124b) to the PBX 110, and the release (REL 1126a, 1126b) and release confirmation (REL COMP 1128a, 1128b) are exchanged between the PS 130 and the PBX 110.

  Thereafter, when the disconnection 1130 of the extension telephone 2000 is sent to the PBX 110, the following processing is performed. Call setting (SETUP 1132b, 1132a) is sent from the PBX 110 to the PS 130. Call setting acceptance (CALL PROC 1134b, 1134a) is returned, respectively. Calls (ALERT 1136a, 1136b) are sent from the PS 130 to the PBX 110. Thereafter, a response (CONN 1138a, 1138b) is sent from the PS 130 to the PBX 110. An incoming call 1140 is made from the PBX to the extension telephone 2000. A ringing tone 1142 is sent from the PBX 110 to the PS 130. Thereafter, when the extension telephone 2000 returns a response 1144, a call between the extension telephone 2000 and the PS 130 is started (during call 1150).

  FIG. 12 shows an embodiment in the case where camp-on (waiting) registration is performed from the extension telephone to the PS 130 when the PS 130 is busy.

  First, when there is a call from the extension telephone 2000 to the PS 130 corresponding to the extension telephone 3001, the PS 130 is busy with the PS management information 610 (STAT 616 is “3”), so a busy tone is transmitted to the extension telephone 2000. To do.

  On the other hand, when the hooking signal and the camp-on special number 15 are transmitted from the extension telephone, the PBX 110 registers the camp-on with respect to the PS 130 from the extension telephone 2000, and sends an camp-on confirmation confirmation sound to the extension telephone 2000. The extension telephone user confirms this and disconnects the call.

  Thereafter, when the call of PS 130 corresponding to the extension telephone 3001 is released, the released call is detected from the line number of the released fixed network line trunk using the call management table, and the O-PS of this CDN, Alternatively, since 3001 corresponding to the extension number of the PS 130 is set in the T-PS, the STAT 616 corresponding to the extension telephone 3001 in the PS management information 610 becomes empty “0”. The PBX 110 performs processing for periodically monitoring the vacant state of the extension number during camp-on registration. When the vacancy of the PS 130 is detected by this monitoring, the extension telephone (EX-TEL) is first called back. When the extension telephone answers this call back, it calls PS130. When PS 130 responds, the connection between extension telephone 2000 (EX-TEL) and PS 130 is completed.

  Note that the STAT 616 of the PS management information 610 corresponding to the extension number (3001) is 2 (incoming) during a call, and is 3 (during a call) after answering.

  Details of FIG. 12 are as follows. In the following description, the update processing of the PS management information 610 and the call management table 630 is omitted for the sake of clarity and to avoid redundant description.

  Assume that PS 130 is busy. First, there is a call 1202 from the extension telephone 2000 to the PBX 110. The extension telephone 2000 dials the extension number 3001 (1204). Since the PS 130 having the extension number 3001 is busy, the PBX 110 sends a busy tone 1206 to the extension telephone 2000. The extension telephone 2000 hooks (1208) and dials the camp-on special number 15. At this point, the PBX 110 performs a camp-on registration process 1201. The PBX 1212 sends a reception confirmation sound 1212 to the extension telephone 2000. The extension telephone 2000 executes disconnection (1214).

  Thereafter, a process for ending the busy of PS 130 is performed. The disconnection (DISC 1216a, 1216b) is sent from the PS 130 to the PBX 110. Release (REL 1218a, 1218b) and release completion (REL COMP 1220a, 1220b) are exchanged, respectively. At this point, the PBX 110 knows that the call related to the PS 130 has been released. Therefore, the extension telephone 2000 receives the incoming call 1222 from the PBX 110. The extension telephone 2000 answers (1224). In response to this response, the PBX 110 sends a call setting (SETUP 1226b, 1226a) to the PS 130. Call setting acceptance (CALL PROC 1228b, 1228a) is returned. Then, a call (ALERT 1230a, 1230b) is sent from the PS 130 to the PBX 110. Then, a ringing tone 1232 is sent from the P-PHS 104 to the extension telephone 2000. Then, responses (CONN 1234a, 1234b) are sent from the PS 130 to the PBX 110. When the response confirmation CONN ACK 1236 is returned, a call between the extension telephone 2000 and the PS 130 is started (busy 1240).

  For the extension representative, the HTG 619 information of the PS management information 610 and the STAT 616 information may be used. When an incoming call extension is in use with respect to an incoming call within the same extension representative group, a process for receiving an incoming call at another extension within the same extension representative group can be performed.

  The management of extension representative groups of extension telephones and the processing of extension representatives may be realized by using basic functions (not shown) that the PBX originally has.

  FIG. 13 shows a functional block diagram of one embodiment. In this embodiment, a state storage unit 1302, a table 1304, a determination unit 1306, and an additional service control unit 1308 are included.

  Call information and a special number instruction (1310) may be input to the status storage unit 1302 and the additional service control unit 1308. The state storage unit acquires the state of the public mobile terminal and the call state based on the call information and instructions. The acquired information may be used to update the table 1304. Specific examples of the table 1304 include, but are not limited to, PS management information 610 and a call management table 630 shown in FIG. For example, the determination unit 1306 may check the calling number of the connected public mobile terminal and check whether the public mobile terminal is a terminal having an extension number. Then, the additional function exemplified in this specification may be provided only for the processing related to the public mobile terminal having the extension number. Further, in the processing related to the pickup, it may be checked whether or not a plurality of terminals related to the pickup belong to the same pickup group. In addition, as described above, the extension representative HTG 619 may be used to determine processing related to the extension representative. The supplementary service control unit 1308, based on the call, the instruction 1310, the information in the table 1304, the information in the determination unit 1306, and the like, for example, the extension supplementary services such as transfer, hold / hold release, pickup, camp-on, etc. provide. Note that the types of services are not limited to these.

  FIG. 14 shows a processing flow of one embodiment.

  FIG. 14A shows an example of the processing flow for updating the table 1304. This processing flow may be started by an interruption due to various events such as a change in the state of a call or an instruction by a special number (1402).

  In step 1404, for example, it is determined whether the state of the mobile terminal has changed. If the determination result is “Yes”, the process proceeds to Step 1406. If the determination is “No”, the process proceeds to Step 1408.

  In step 1406, the contents of the table 1304 are updated. For example, the state of the STAT 618 in the PS management information 610 in FIG. 6 may be updated based on the correspondence table 620.

  In step 1408, for example, it is determined whether the call state has changed. If the determination result is “Yes”, the process proceeds to Step 1410. If the determination result is “No”, the process returns (1412).

  In step 1410, the contents of the table 1304 are updated. For example, the contents of the call management table 630 in FIG. 6 may be updated.

  FIG. 14B shows a flow of additional service control processing. This processing flow may be initiated by an interrupt due to various events such as a change in the state of a call or an instruction by a special number (1452).

  In step 1453, for example, the calling number of the connected public mobile terminal may be checked, and it may be checked whether or not the public mobile terminal is a terminal having an extension number. Then, only the process related to the public mobile terminal having the extension number may be instructed to step 1454 to provide the additional function exemplified in this specification. Further, in the processing related to the pickup, it may be checked whether or not a plurality of terminals related to the pickup belong to the same pickup group. Further, as described above, the extension representative HTG 619 may be used to determine the processing related to the extension representative. These determination results are passed to step 1454.

  In step 1454, processing for providing services such as transfer, hold / hold release, pick-up, camp-on, etc., which are extension services, for example, is performed. Note that the specific processing contents are as described above using, for example, the sequences of FIGS. 6 to 12 are examples, and the sequence order may be changed as long as there is no contradiction. In addition, it goes without saying that other sequences may be adopted in order to realize the same function.

  According to at least one of the plurality of embodiments described above, it is not necessary to add functions of the public mobile terminal and the mobile carrier network. Then, additional services of the PBX 110 can be used for public mobile terminals. For this reason, facilities (antenna, transmitter / receiver, etc.) such as a self-employed PHS are not required in the office, and the cost can be reduced. In addition, it is possible to improve the services of public mobile terminals and users of PBX 110 extensions.

  In the above description, both the PS management information 610 and the call management table 632 may be stored in the storage unit in a table format. For convenience of explanation, FIG. 6 is divided into two tables, but the table may be further divided or may be combined into one. Further, it goes without saying that the information of these tables does not need to maintain the table format in the storage unit.

  Moreover, you may implement | achieve operation | movement of various embodiment of this invention only in a specific transmission origin and the group of a specific transmission origin.
