Description

  The present invention relates to a telephone system, a telephone call transfer method, and a telephone call transfer program.

  In recent years, as a communication terminal, in addition to a conventional fixed desk phone terminal, a mobile phone terminal, a personal digital assistant (PDA), a software phone terminal that operates on a computer, and the like have appeared. A system in which a plurality of telephone terminals owned by one user is managed by a single user number (or extension number) has been studied. Further, as a form of development of such a system, a telephone call is made based on presence information (presence information) indicating a user's location where the user is present until recently in which of the plurality of telephone terminals. A telephone system that determines whether or not a telephone terminal is capable of answering a call or responding to an incoming call, and transfers a telephone call to the telephone terminal that the user has determined to be able to answer It is being considered.

  An example of a telephone system for transferring a telephone call based on presence information, which has been studied so far, is disclosed in Japanese Patent Application Laid-Open Publication No. 2006-238428, “Method and System for Transferring a Telephone Call Based on Presence Information”. "It is described in. A telephone system for transferring a telephone call based on the presence information described in Patent Document 1 has a system configuration as shown in FIG. FIG. 8 is a system configuration diagram showing a system configuration of the telephone system described in Patent Document 1. As shown in FIG.

  As shown in FIG. 8, the telephone system includes a presence system 50, a telephone exchange 60, client computer systems 71, 72,... 73, and telephone terminals 91 associated with the client computer systems 71, 72,. , 92, and 93, and the client computer systems 71, 72,..., 73 are connected to the presence system 50 and the telephone exchange 60 via a communication link 80.

  Here, the presence system 50 holds the current presence status of each user who uses the telephone system (that is, information indicating the current location of each user). When the computer systems 71, 72, ..., 73 are used, the client computer system in which the user was last active can be identified as the presence information of the client computer systems 71, 72, ..., 73. . That is, it is possible to identify which client computer system the user has operated most recently.

  The telephone exchange 60 controls the operation of making and receiving telephone calls from the telephone terminals 91, 92,..., 93 associated with the client computer systems 71, 72,. It consists of a private branch exchange (PBX), a packet switch, a VoIP (Voice over Internet Protocol) server, and the like. Further, the client computer systems 71, 72,..., 73 exemplify a computer system used by a certain user, and such a plurality of client computer systems are used by a single user according to their location. An example that makes it possible. The client computer systems 71, 72,..., 73 are, for example, a desktop PC (Personal Computer), a laptop PC, a portable information terminal, or the like.

  Further, telephone terminals 91, 92,..., 93 are associated with the client computer systems 71, 72,..., 73, respectively, and indicate a plurality of telephone terminals used by the user. It consists of telephone terminals, PHS terminals, software telephone terminals, and the like. Each of the client computer systems 71, 72,... 73 receives presence information indicating the latest location of the user from the presence system 50 and holds it. The telephone system shown in FIG. 8 having such a configuration operates as follows.

  When the telephone exchange 60 accepts a telephone call to a telephone terminal of a certain user, the telephone exchange 60 sends all of the client computer systems 71, 72,..., 73 associated with the telephone number of the user. Send the phone call.

  On the other hand, the presence system 50 allows each client computer system 71, 72,..., 73 to subscribe to the presence information of each other client computer system, and each client computer system 71, 72,. ..., 73 holds presence information indicating the latest state of the user. For example, when the presence system 50 receives updated presence information about a certain client computer system, for example, the client computer system 71 from the client computer system 71, the presence system 50 is permitted to subscribe to the updated information on the presence information of the client computer system 71. All other client computer systems such as client computer systems 72,.

  When each client computer system 71, 72,..., 73 used by a certain user receives an incoming call event from the telephone exchange 60 for each client computer system, the client computer system refers to presence information possessed by each client computer system. Thus, it is determined whether or not the user was last active at the location of the client computer system, that is, the client computer system among the client computer systems 71, 72,. It is determined whether or not the computer system has been operated until the time.

  For example, if the user was last active at the location of the client computer system 71, the client computer system 71 notifies the telephone exchange 60 of a telephone terminal associated with the client computer system 71, such as a telephone terminal 81. Request to forward the outgoing call. On the other hand, the remaining client computer systems 72,..., 73 determined not to be the user's last active computer system do not perform an operation of requesting the telephone switch 60 to transfer a telephone call.

JP 2006-238428 A (page 6-9)

  As described above, in the conventional technique described in Patent Document 1, the destination of the telephone call is determined based on the presence information on the telephone receiving side, and the presence information is sent to the client computer system. If it is set in advance, for example, when the user on the incoming side is out, the outgoing call is automatically transferred to the mobile phone terminal carried by the user, while on the other hand, By automatically transferring a telephone call to a desktop fixed telephone terminal, it is possible to automatically make a telephone call to a telephone terminal that is most likely to be answered by a user on the receiving side.

  However, as described above, the selection operation in which the transfer destination telephone terminal is selected based only on the presence information of the incoming call side at the time of the incoming call is the incoming side telephone terminal that can immediately respond to the incoming call. Only the immediacy of communication is considered.

  For this reason, if you use the same carrier's telephone service as the communication path from the calling party's telephone terminal to the called party's telephone terminal, you want to use the telephone service of various carriers such that the communication fee will be fixed. Even in such a case, the communication path is determined only by the incoming telephone terminal regardless of the outgoing telephone terminal. For example, if a call comes from one of the mobile phone operators' mobile phone terminals, even if the mobile phone operator's mobile phone terminal is provided on the receiving side, depending on the presence information on the receiving side The incoming call can be received only at the determined telephone terminal, and the incoming call cannot be made at the mobile telephone terminal for the mobile communication carrier.

  Therefore, taking into account information about the telephone terminal on the calling side, the communication path is determined according to the telephone service of the telecommunications carrier, and then the communication path of the same telecommunications carrier between the outgoing and incoming telephone terminals. It is not possible to implement a mechanism for making a direct call using the mobile phone, and the communication service by the telecommunications carrier becomes diverse, such as a flat fee for communication between telephone terminals for the same telecommunications carrier. In the meantime, there has been a problem that the benefit of the telephone service of such a carrier cannot be fully received.

(Description of operation of the first embodiment)
Next, an example of the operation of the telephone system according to the first embodiment of the present invention shown in FIG. 1 will be described in detail.

  When the telephone terminals 31, 32, 33, and 34 for each user are registered in the telephone exchange 20 in the telephone terminal information registration table 1 shown in FIG. 2 and the user telephone number registration table 2 shown in FIG. The telephone terminal name for identifying the terminal, the user name for identifying the user, the user number for uniquely identifying the user, the telephone number of the telephone terminal, as well as the carrier code 1c of the telephone terminal information registration table 1 In addition, as shown in the identification code (Company A, Company B) for uniquely identifying the communication carrier and the terminal classification 1d in the telephone terminal information registration table 1, identification information such as the terminal classification (mobile phone, fixed telephone) is also included. sign up.

  Further, the telephone exchange 20 periodically accesses the user presence information setting table 4 of FIG. 5 held by the presence system 10 at a predetermined cycle, and the latest location of the user who uses each telephone terminal. Presence information indicating is acquired. Instead of accessing the presence system 10 from the telephone exchange 20, the presence system 10 may periodically transmit the presence information of each user to the telephone exchange 20 at a predetermined period. Alternatively, it may be transmitted whenever presence information is changed.

  Next, when the telephone exchange 20 receives presence information about the user of each telephone terminal from the presence system 10, the telephone exchange 20 refers to the destination registration table 3 according to receiver presence for each telephone terminal and calls the user on the receiving side. Based on the correspondence relationship between the recipient presence 3b indicating the presence information of the caller and the caller terminal type 3a indicating the terminal type of the caller telephone terminal, the optimum communication path and the callee of the callee in the current situation of the callee user The terminal, that is, the telephone number indicating the optimum destination is obtained.

  That is, the telephone exchange 20 uses the telephone terminal information registration table 1 in FIG. 2, the user telephone number registration table 2 in FIG. 3, and the destination presence-specific destination registration table 3 in FIG. For each telephone terminal, the user name of each destination that is the call destination is associated with the destination telephone number of the telephone terminal that is the optimal destination, and is generated as user destination information, with a predetermined cycle Periodically notify each telephone terminal corresponding to the caller, or change the user destination information from the previous notification (that is, the terminal type of the caller terminal and the presence of the user of the callee) When the information change occurs, the changed user destination information is notified to the corresponding telephone terminals.

  For example, when the presence information of the user 3 is “attended”, the user 3 is connected to the mobile phone terminal 31 for company A used by the user 1 in preparation for making a call to the user 3. And the telephone number 'DDDD' of the mobile phone terminal 34 for company A carried by the user 3 so as to use the same communication path of the carrier A as the user 1 as the destination telephone number. In addition, for the company B mobile phone terminal 32 used by the user 2, the destination user 3 uses only a telephone terminal of a communication carrier different from the user 2, indicating the user 3. Along with the user name, the telephone number “CCCC” of the fixed telephone terminal 33 to which the user 3 who is present can respond immediately is notified as the destination telephone number.

  Each telephone terminal that has received the user destination information notified from the telephone exchange 20 is based on the received user destination information, and indicates a telephone number indicating a telephone terminal to which the user of each telephone terminal that is the destination can respond. That is, the communication path for each destination and the destination telephone terminal) are edited in a format associated with each destination user, and set and registered by overwriting the destination registration table 5 shown in FIG. . The destination registration table 5 is overwritten each time user destination information is received from the telephone exchange 20.

  When each telephone terminal dials a user number for uniquely identifying a destination user who is a call partner when making a call, the telephone terminal refers to the destination registration table 5 in FIG. The dial information (telephone number indicating the destination) is converted into a destination telephone number corresponding to the dialed user number, and a telephone call is made. Thus, it is possible to set a route for making a call between the outgoing and incoming phone terminals using the optimum communication route according to the combination of the terminal types of both the incoming and outgoing phone terminals and the presence information of the user on the incoming side. it can.

  For example, when the company A mobile phone terminal 31 used by the user 1 dials the user number '0003' uniquely identifying the user 3 and makes a call, the destination presence-specific destination registration table 3 in FIG. As shown in the receiver presence 3b, the presence information (information indicating the current location) of the destination user 3 is stored in the destination registration table 5 of the user A's mobile phone terminal 31 of company A. Regardless of whether it is “going out” or “going out”, the telephone number “DDDD” is set as the destination telephone number 5c. Accordingly, in the mobile phone terminal 31 for company A, the destination registration table 5 is indexed by the user number “0003”, and the mobile phone terminal 34 for company A having the telephone number “DDDD” is used as the telephone terminal of the user 3 as the destination. When selected, a telephone call is made to the mobile phone terminal 34 for company A having the telephone number “DDDD”, and direct communication is performed via the wireless communication network 100 operated by the carrier of company A.

  As a result, in the case of a telephone call between telephone terminals of the same carrier such as the mobile phone terminal 31 for company A and the mobile phone terminal 34 for company A, the destination user 3 uses the fixed telephone terminal 33 when the user 3 is present. Even if it is possible, by transferring to the mobile phone terminal 34 for Company A, it is possible to fully enjoy the communication service of the carrier of Company A, for example, it is possible to perform communication at a flat rate become.

  On the other hand, even when communication is performed between mobile phone terminals, such as between the mobile phone terminal 32 for company B used by the user 2 and the mobile phone terminal 34 for company A used by the user 3, different communication is performed. In the case of communication between the telephone terminals of the business operators, as shown in the receiver presence 3b of the receiver registration table 3 by receiver presence in FIG. 5, the telephone number “CCCC” is set as the destination telephone number 5 c when the presence information of the destination user 3 is “present”, and the telephone number “DDDD” is set as the destination telephone number 5 c when “outing”. Has been. Therefore, only when the presence information of the destination user 3 is “going out”, the call is made to the mobile phone terminal 34 for company A with the telephone number “DDDD” carried by the user 3, but the destination user 3 When the presence information is “attended”, the telephone call to the fixed telephone terminal 33 with the telephone number “CCCC” is selected, and the call is transferred to the fixed telephone terminal 33 that can be used immediately by the user 3. It is possible to select a proper communication path.

  Note that the setting trigger of the destination registration table 5 in FIG. 6 held by each telephone terminal is not limited to the above case. For example, depending on the time of day, the communication charge may be lower for the call service between the mobile phone terminal and the mobile phone terminal than for the call service between the mobile phone terminal and the fixed phone terminal. The setting contents of the destination registration table 5 in FIG. 6 may be changed and set for each time zone.

  Alternatively, the setting contents of the destination registration table 5 in FIG. 6 may be set according to the organization to which the destination user belongs. For example, the telephone terminals used by employees belonging to the same organization are overwhelmingly often used by the same carrier, so when the user 1 goes out with the mobile phone terminal 31 for company A In addition, when making a call to the user 3 who is an employee of the same organization as the user 1, the incoming call shown in FIG. By setting the setting contents of the destination registration table 5, it is possible to reduce the communication fee.

(Description of the effect of the first embodiment)
As described in detail above, the telephone system according to the first embodiment of the present invention has the following effects. In other words, it is possible to select a communication path as intended by the system administrator of the telephone system without making the user aware of it while ensuring the desired immediacy of certain communication. The reason is that a mechanism that can flexibly select an optimal communication path is adopted depending on the combination of the terminal type of both the outgoing and incoming telephone terminals and the presence information of the user on the incoming side.

(Second Embodiment)
Next, a transfer example of a telephone call that is different from the first embodiment will be described as a second embodiment.

  In the first embodiment described above, a case has been described in which an optimal communication path is selected and a telephone call is transferred based on a combination of the terminal types of both the outgoing and incoming telephone terminals and the presence information of the receiving user. However, an optimal communication path may be selected according to a combination of presence information of both the incoming and outgoing users to transfer a telephone outgoing call.

  That is, in the second embodiment, instead of the destination registration table by destination presence shown in FIG. 4 of the first embodiment, the destination registration table by destination presence 6 shown in FIG. It is held in the exchange 20.

  FIG. 7 is a table showing an example of a destination registration table according to the presence / absence of a caller / caller held in the telephone switch 20 in the telephone system of FIG. 1, and one of the telephone terminals connected to the telephone switch 20 is shown in FIG. For all telephone terminals in the case where there are a plurality of telephone terminals used by the user, for each user, a combination of the presence information of the caller and the presence information of the user on the receiving side and the incoming call for each user on the receiving side The association with the previous telephone number is registered in advance.

  That is, the destination registration table 6 by caller presence / presence of FIG. 7 shows the caller presence 6a indicating the presence information of the caller user (that is, the caller) and the presence information of the callee user (that is, the callee). It is configured to include at least the correspondence relationship of the destination telephone number determined from the combination with the receiver presence 6b. In addition, in the destination registration table 6 according to the presence / absence of the caller / caller in FIG. 7, the caller is the user 1 who uses the company A mobile phone terminal 31 and the callee is the user 3 who uses two phone terminals. Is shown as an example.

  For example, as shown in the caller presence 6a and the callee presence 6b, the user 1 who uses the mobile phone terminal 31 for company A on the caller side is present and the user 3 on the callee side is also present. Only when the user is present, the fact that the telephone number “CCCC” of the fixed telephone terminal 33 out of the two telephone terminals used by the user 3 on the receiving side is to be used as a destination is registered. In the case of other combinations of both incoming calls (ie, when the caller is out or when the callee is out), the two phones used by the called user 3 Among the terminals, the fact that the telephone number “DDDD” of the mobile phone terminal 34 for company A is to be used as a destination is registered.

  Similarly to the setting operation to the destination presence destination registration table 3 in FIG. 4 in FIG. 4 in the first embodiment, the telephone exchange 20 periodically holds the user presence in FIG. 5 held by the presence system 10 at a predetermined cycle. The information setting table 4 is accessed to obtain presence information indicating the latest location of the user who uses each telephone terminal. Instead of accessing the presence system 10 from the telephone exchange 20, the presence system 10 may periodically transmit the presence information of each user to the telephone exchange 20 at a predetermined period. Alternatively, it may be transmitted whenever presence information is changed.

  Next, when receiving the presence information regarding the user of each telephone terminal from the presence system 10, the telephone exchange 20 refers to the destination registration table 6 according to calling party presence in FIG. Based on the correspondence between the caller presence 6a indicating the presence information of the user and the callee presence 6b indicating the presence information of the destination user, the optimum destination in the current situation of each user between the caller and the callee Get the phone terminal or phone number.

  That is, the telephone exchange 20 uses the telephone terminal information registration table 1 in FIG. 2, the user telephone number registration table 2 in FIG. 3, and the destination registration table 6 by calling party presence in FIG. For each telephone terminal, the user name of each destination that is the call destination is associated with the destination telephone number of the telephone terminal that is the optimal destination, and is generated as user destination information, with a predetermined cycle Periodically, each telephone terminal corresponding to the caller is notified, or each time the user destination information is changed from the previous notification (that is, the presence information of the user of the outgoing / incoming user is changed), The changed user destination information is notified to the corresponding telephone terminals.

  For example, when the presence information of the user 3 is “present”, the user A uses the mobile phone terminal 31 for Company A used by the user 1 in preparation for making a call to the user 3. When the presence information of 1 is “attended”, the telephone of the fixed telephone terminal 33 that can be immediately answered by the user 3 present as the destination telephone number together with the user name indicating the user 3 When the number “CCCC” is notified and the presence information of the user 1 is “going out”, the communication path of the same carrier A company as the user 1 is used as the destination telephone number together with the user name indicating the user 3. The phone number “DDDD” of the mobile phone terminal 34 for company A carried by the user 3 is notified so as to be used.

  Each telephone terminal that has received the user destination information notified from the telephone exchange 20 is based on the received user destination information, and indicates a telephone number indicating a telephone terminal to which the user of each telephone terminal that is the destination can respond. That is, the communication path for each destination and the destination telephone terminal) are edited in a format associated with each destination user, and set and registered by overwriting the destination registration table 5 shown in FIG. . The destination registration table 5 is overwritten each time user destination information is received from the telephone exchange 20.

  When each telephone terminal dials a user number for uniquely identifying a destination user who is a call partner when making a call, the telephone terminal refers to the destination registration table 5 in FIG. The dial information (telephone number indicating the destination) is converted into a destination telephone number corresponding to the dialed user number, and a telephone call is made. Thus, by combining the presence information of both the incoming and outgoing users, it is possible to set a route for making a call between the outgoing and incoming telephone terminals using the optimum communication route.

(Third embodiment)
Next, a transfer example of a telephone call that is further different from the first embodiment will be described as a third embodiment.

  In the first embodiment described above, the telephone exchange 20 refers to the telephone terminal information registration table 1 in FIG. 2 and the called party presence-specific destination registration table 3 in FIG. In the third embodiment, the telephone exchange 20 has been described with reference to FIG. 2 in which the optimum communication path is selected and the telephone outgoing call is transferred according to the combination of the presence information of the user on the called side. Instead of holding the telephone terminal information registration table 1, each time the outgoing telephone terminal makes a call, identification information, that is, the terminal type of the telephone terminal and the carrier type code (Company A, Company B, etc.) are exchanged. The telephone exchange 20 that has received the identification information about the outgoing call accesses the presence system 10 and acquires the presence information on the called side each time. It determines the transfer destination becomes a telephone call destination, shows the case of performing the transfer process.

  For example, from the mobile phone terminal 31 for company A used by the user 1, the user ID of the user 3 together with the identification information relating to the outgoing call, that is, the terminal type and the communication carrier type code (company A, company B, etc.) When the telephone call information including the dial information “0003” is received, the telephone exchange 20 accesses the user presence information setting table 4 held by the presence system 10 and acquires the presence information regarding the user 3 on the receiving side.

  The telephone exchange 20 that has acquired the presence information regarding the user 3 on the called side, that is, the presence of the called party, receives information on the outgoing call (terminal type, carrier type code, etc.) received from the telephone terminal on the calling side, 4, the callee registration table 3 by callee presence in FIG. 4 is referred to, the callee telephone number indicated by the presence information of the callee user 3 is obtained, and the call originating call from the user 1 to the user 3 is obtained. Is the fixed telephone terminal 33 having the telephone number 'CCCC' or the mobile phone terminal 34 for company A having the telephone number 'DDDD'. Thereafter, the telephone exchange 20 converts the user number “0003” of the dial information included in the telephone call information from the caller telephone terminal into the determined caller telephone number, and converts the call call information into Send in relay form.

  Here, when the transfer destination of the telephone outgoing call is determined, the telephone exchange 20 determines that the communication between the determined outgoing and incoming telephone terminals is to make a direct call via the wireless communication network. Instead of relaying call transmission information, if necessary, make a direct call via the wireless communication network to both the call terminal and either the call terminal. A command instructing to do so is sent out, and a transfer process to the wireless communication network is performed. Thus, it is possible to set a route for making a call between the outgoing and incoming phone terminals using the optimum communication route according to the combination of the terminal types of both the incoming and outgoing phone terminals and the presence information of the user on the incoming side. it can.

  Note that the destination registration table 3 by recipient presence in FIG. 4 can be set by changing to different information (telephone number indicating the destination) for each time zone, and calling from the telephone terminal on the caller side When the information is received, the telephone exchange 20 acquires the time when the telephone call information is received, and refers to the setting contents of the destination registration table 3 according to the receiver presence in the time zone corresponding to the time. May be.

  The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such examples are merely illustrative of the invention and do not limit the invention in any way.
