1-5. Functional Configuration of Server Device FIG. 7 is a diagram illustrating a functional configuration of the server device 1. The control unit 11 functions as a detection unit 111, a request unit 112, an acquisition unit 113, a specification unit 114, a calculation unit 115, and a selection unit 116. The detection unit 111 monitors the communication content sent from the terminal 2 to the server device 1 via the communication unit 13, and detects the transmission transmitted by the terminal 2a, which is the transmission side terminal, from the communication content. When the request unit 112 analyzes the content of the outgoing call detected by the detection unit 111 and specifies the terminal 2b for which a call is requested, the request unit 112 requests connection to the terminal 2b.

  When the request unit 112 receives a notification indicating that the connection is accepted from the terminal 2b as a response to the connection request, the request unit 112 forms a communication path between the terminal 2a and the terminal 2b. On the other hand, when the request unit 112 receives notification from the terminal 2b that the connection is rejected and the incoming call is transferred, the request unit 112 notifies the acquisition unit 113 of the notification.

  The acquisition unit 113 refers to the transfer destination database 121 stored in the storage unit 12 when the request unit 112 receives a notification that the incoming call is to be transferred from the terminal 2b. The telephone number of the terminal 2b is searched. Then, the acquisition unit 113 reads the transfer destination list 1211 associated with the telephone number of the terminal 2b, and generates the transfer destination table 110 on the RAM of the control unit 11.

  The specifying unit 114 reads the telephone number of the terminal 2c that is a candidate for the transfer destination described in the transfer destination table 110, and provides the position information indicating the position to the terminal 2c that is the transfer destination identified by each telephone number. Request. The specifying unit 114 also requests location information indicating the location from the terminal 2a that has made the transmission detected by the detection unit 111. Receiving this request, each terminal 2 (terminal 2a and terminal 2c) measures the position of its own device by each positioning unit 28, and transmits position information indicating the position to the server device 1 via the communication network 3. . The communication unit 13 of the server device 1 receives the position information from each terminal 2 and transmits it to the specifying unit 114. The specifying unit 114 acquires the position information of each terminal 2, specifies the position of each terminal 2, and writes the position information in the transfer destination table 110.

  When the location information of the terminal 2a on the transmission side and each terminal 2c that is a transfer destination candidate is written into the transfer destination table 110 by the specifying unit 114, the calculation unit 115 calculates the distance between the terminal 2a and each terminal 2c. The calculation result is written in the transfer destination table 110. And the calculation part 115 rearranges each terminal 2c in order with the shortest written distance, and ranks it. The selection unit 116 sequentially selects each terminal 2c ranked by the calculation unit 115 in accordance with the rank, and tries to transfer the incoming call from the terminal 2b to the selected terminal 2c.

1-6. Operation of Call System FIG. 8 is a flowchart for explaining the operation of the call system 9. The control unit 11 of the server device 1 monitors the state of the terminal 2 and determines whether or not a transmission is detected from the terminal 2 (step S101). And while transmission is not detected (step S101; NO), the control part 11 continues this determination. When the transmission from the terminal 2 (hereinafter, this terminal 2 is referred to as the terminal 2a) is detected (step S101; YES), the control unit 11 analyzes the content of the transmission and analyzes the incoming terminal 2 (hereinafter, this terminal 2). A connection request is made to the terminal 2b (step S102).

  Next, the control unit 11 determines whether or not it has been requested to transfer the incoming call from the terminal 2b as a response to the connection request in Step S102 (Step S103). When it is determined that the terminal 2b does not request transfer of the incoming call (step S103; NO), the control unit 11 connects the terminal 2a and the terminal 2b to form a speech path (step S104), and performs processing. finish.

  On the other hand, when it is determined that the terminal 2b is requesting transfer of the incoming call (step S103; YES), the control unit 11 refers to the transfer destination database 121 stored in the storage unit 12 and refers to the telephone number of the terminal 2b. The transfer destination list 1211 associated with is acquired, and the transfer destination table 110 is generated based on the acquired transfer destination list 1211 (step S105). Then, the control unit 11 specifies the position of the terminal 2a on the transmission side (step S106), and the terminals 2 described in the transfer destination table 110 as the transfer destination of the terminal 2b on the reception side (hereinafter, these terminals 2). Is identified as a terminal 2c) (step S107). The order of step S106 and step S107 may be the reverse of the order described above. When the respective positions of the terminal 2a and each terminal 2c are specified, the control unit 11 writes position information indicating these positions in the corresponding columns of the transfer destination table 110.

  The control unit 11 calculates each distance between the terminal 2a and each terminal 2c based on the position information in the transfer destination table 110 (step S108). Specifically, it is as follows.

  If the coordinates indicating the position of the terminal 2a are (X0, Y0) and the coordinates indicating the position of the terminal 2c are (X1, Y1), the distance L between the terminal 2a and the terminal 2c is calculated by the following equation (1). The

  FIG. 9 is a diagram illustrating an example of the transfer destination table 110 that changes with the operation of the call system 9. In the transfer destination table 110 illustrated in FIG. 9A, a position information column is written according to position information indicating the position of each terminal 2 specified by the control unit 11 functioning as the specifying unit 114. For example, in the transfer destination table 110 shown in FIG. 9A, since the terminal 2a is associated with the rank “0”, the telephone number is “03-xxxx-xxx1”, and the position information indicating the position Is (210, 200). That is, X0 = 210 and Y0 = 200. In the transfer destination table 110 shown in FIG. 9A, the terminal 2c with the rank “1” has the telephone number “03-xxx-xxx6” and the position information is (100, 100). That is, X1 = 100 and Y1 = 100. When these are substituted into the above equation (1), the distance L = 148.86. The control unit 11 writes the calculated distance L for each terminal 2c in the distance column of the transfer destination table 110 shown in FIG. Since it is obvious that the distance between the terminal 2a and its own device is 0.00, the calculation need not be performed.

  When the distance column is written for all the terminals 2, the control unit 11 sorts the transfer destination table 110 based on each distance. In other words, the order of each row in the transfer destination table 110 is switched so that the shorter the distance, the higher. By this operation, the transfer destination table 110 shown in FIG. 9A is rearranged to become the transfer destination table 110 shown in FIG. 9B.

  When rearrangement is performed for all the terminals 2c described in the transfer destination table 110, the control unit 11 selects the terminals 2c in accordance with the order (step S109), and requests connection to the selected terminals 2c. The terminal 2b tries to transfer the incoming call (step S110).

  Then, the control unit 11 determines whether or not there is a response to the connection request described above from the selected terminal 2c (step S111), and determines that there is no response (step S111; NO). Continue. If it is determined that there is a response (step S111; YES), the control unit 11 connects the terminal 2a and the terminal 2c to form a speech path (step S112), and ends the process.

  For example, when the transfer destination table 110 shown in FIG. 9B is obtained by the rearrangement, the control unit 11 first selects the terminal 2c having the rank “1”, and the telephone number “090-xxxx”. Attempt to transfer the incoming call of terminal 2b using -xxx8 ". If there is no response from the selected terminal 2c even after a predetermined time has elapsed, the control unit 11 selects the terminal 2c with the rank “2”. And the control part 11 tries to transfer the incoming call of the terminal 2b, using the telephone number "03-xxxx-xxx9".

  As described above, in the call system 9, the server device 1 selects and transfers the incoming call of the terminal 2b requesting transfer from the transfer destination terminals 2c registered in association with the terminal 2b. Try to do so. The transfer destination terminal 2c is selected with priority as the distance from the caller terminal 2a is shorter. Therefore, for example, since the delivery person's terminal 2c with a short distance to the user (sender) of the terminal 2a on the calling side receives the transfer preferentially, the delivery person who owns the transferred terminal 2c It will be easier to contact the caller directly.

2. Modification The above is the description of the embodiment, but the contents of this embodiment can be modified as follows. Further, the following modifications may be combined.
2-1. Starting point of distance In the above-described embodiment, the terminal 2 that is the starting point when calculating the distance to each terminal 2c is the originating terminal 2a, but the receiving terminal 2b may be the starting point. FIG. 10 is a flowchart for explaining the operation of the call system 9 in this modification. In this modification, the control unit 11 of the server device 1 executes step S106a instead of step S106 described in the embodiment, and executes step S108a instead of step S108. In step S106a, the control unit 11 specifies the position of the terminal 2b on the incoming side, not the position of the terminal 2a on the outgoing side. In step S108a, the control unit 11 calculates each distance between the terminal 2b and each terminal 2c. With this configuration, for example, the delivery person's terminal 2c that is close to the user (recipient) of the terminal 2b on the receiving side is preferentially transferred, so the delivery person who owns the transferred terminal 2c. Makes it easy to get in touch with the callee directly.

2-2. Elimination of duplicate forwarding destinations In the above-described embodiment, the forwarding destination list 1211, which the forwarding destination database 121 has for each terminal 2b on the receiving side, does not affect the operation regardless of which terminal 2 is described as the forwarding destination. However, when the transfer destinations described in the respective transfer destination lists 1211 overlap, the control unit 11 may be configured to execute a process different from the case where the transfer destinations do not overlap.

  FIG. 11 is a diagram showing the configuration of the server device 1b in this modification. The server device 1 b includes a control unit 11 b instead of the control unit 11 in the embodiment, and a storage unit 12 b instead of the storage unit 12. The control unit 11b generates a transfer destination table 110b and stores it in the RAM. The storage unit 12b stores a transfer destination database 121b. Since the other structure of the server apparatus 1b is common in the server apparatus 1 of embodiment mentioned above, description is abbreviate | omitted.

  FIG. 12 is a diagram showing a functional configuration of the control unit 11b in this modification. In this modification, the control unit 11b functions as a reception unit 117, a comparison unit 118, and a registration unit 119.

  The accepting unit 117 accepts a signal transmitted from the registration terminal 4 via the interface 14. When receiving a list of terminals 2c determined as transfer destinations for a certain incoming terminal 2b from the registration terminal 4, the reception unit 117 hands over the received list to the comparison unit 118.

  The comparison unit 118 refers to the transfer destination database 121b and compares the telephone number group described in the list delivered from the reception unit 117 with the transfer destination telephone number group described in the transfer destination database 121b. Then, it is determined whether any one of the transfer destination telephone numbers is described in the list delivered from the reception unit 117.

  When there is no duplication described above, the registration unit 119 adds the list delivered from the reception unit 117 to the transfer destination database 121b as a transfer destination list corresponding to the certain terminal 2b on the receiving side. On the other hand, if there is an overlap as described above, the transfer destination database 121b is added with the lowest transfer destination rank in the list delivered from the accepting unit 117.

  FIG. 13 is a diagram showing an example of the transfer destination database 121b in this modification. As illustrated in FIG. 13, the transfer destination database 121b includes a receiving terminal list 1210b and a transfer destination list 1211b. The receiving terminal list 1210b is common to the receiving terminal list 1210 in the embodiment, and thus description thereof is omitted.

  First, the storage unit 12b stores the transfer destination database 121b illustrated in FIG. In FIG. 13A, one telephone number “03-xxxx-xxx1” is described in the receiving terminal list 1210b. One transfer destination list 1211b is stored in association with this telephone number. Unlike the transfer destination list 1211 described above, the transfer destination list 1211b includes a distance calculation column (hereinafter referred to as a calculation column) in addition to a rank column and a telephone number column. This calculation column describes whether or not the distance between the corresponding terminal 2c and the terminal 2a may be calculated. For example, in the transfer destination list 1211b shown in FIG. 13A, “O” is described in the calculation column for all the rows from the rank “1” to “5”. This indicates that the distance between each terminal 2c described in the transfer destination list 1211b shown in FIG. 13A and the terminal 2a is calculated.

  Here, the server apparatus 1b receives a list of a plurality of terminals 2c determined as transfer destinations for a certain terminal 2b from the registration terminal 4 via the interface 14. For example, this list is the list shown in FIG. The telephone number of this certain terminal 2b is “06-xxxx-xxx2”. The control unit 11 functions as the comparison unit 118 described above, and determines whether or not the telephone numbers already described in the transfer destination database 121b are included in the telephone numbers described in this list. judge. In this case, in the transfer destination list 1211b shown in FIG. 13A, the telephone number “03-xxxx-xxx6” is described in association with the rank “1”. The telephone number corresponding to the rank “1” in the list shown in FIG.

  Therefore, the control unit 11 moves the duplicate telephone number to the lowest rank and moves up the rank of other telephone numbers. Then, the list after such adjustment is added to the transfer destination database 121b as the transfer destination list 1211b corresponding to the certain terminal 2b described above. At this time, “×” is described in the calculation column corresponding to the telephone number that has been moved to the bottom of the list because duplication has been found. In other words, the registration unit 119 realized by the control unit 11 includes the telephone number already stored in the transfer destination database 121b by the storage unit 12b in the telephone number received by the reception unit 117. The telephone number is stored in the storage unit 12b as a duplicated telephone number (referred to as a duplicate telephone number) in distinction from other telephone numbers received by the receiving unit 117. The telephone number “06-xxxx-xxx2” of the certain terminal 2 is added to the receiving terminal list 1210b in the transfer destination database 121b.

  FIG. 14 is a diagram showing a transfer destination table 110b in this modification. The transfer destination table 110b is generated on the RAM of the control unit 11b based on the transfer destination database 121b. The transfer destination table 110b is provided with a calculation column in addition to the transfer destination table 110 in the embodiment. The transfer destination table 110b shown in FIG. 14A is a transfer destination list associated with “03-xxxx-xxx1” which is the terminal 2b on the receiving side in the transfer destination database 121b shown in FIG. 13C. It is generated based on 1211b. In the transfer destination table 110b shown in FIG. 14A, the calculation column corresponding to all ranks from “1” to “5” is “◯”. Therefore, the control part 11 requests | requires the positional information from all these terminals 2c, and calculates the distance with the terminal 2a.

  On the other hand, the transfer destination table 110b shown in FIG. 14B is associated with “06-xxxx-xxx2” which is the terminal 2b added later in the transfer destination database 121b shown in FIG. 13C. It is generated based on the transfer destination list 1211b. In the transfer destination table 110b shown in FIG. 14B, the calculation columns corresponding to the rank “1” and the rank “2” are both “◯”, but the calculation corresponding to the rank “3” is performed. The column is “x”. Therefore, the control unit 11 requests the position information from the terminal 2c corresponding to the rank “1” and the rank “2” and calculates the distance to the terminal 2a, but the terminal 2c corresponding to the rank “3” Does not request location information and does not calculate the distance to the terminal 2a. That is, the calculation unit 115 realized by the control unit 11 does not calculate the distance between the terminal 2a corresponding to the duplicate telephone number and the terminal 2a or the terminal 2b.

  As described above, in this modification, the terminal 2c already associated with the transfer destination of the other terminal 2b overlaps with the terminal 2c described in the transfer destination list of the newly added terminal 2b. Sometimes, the rank of the duplicated terminal 2c added later is lowered. And since the distance is not calculated for the terminal 2c whose rank has been lowered, there is no fluctuation in the rank due to this calculation. Therefore, when the terminals 2c described as transfer destination candidates overlap each other, the rank of the terminal 2c added later is lowered, and the rank is fixed. That is, the selection unit 116 realized by the control unit 11 does not calculate the distance for the terminal 2c corresponding to the duplicate telephone number, so that the terminal 2c identified by the telephone number that is not the duplicate telephone number Selection is given priority over the terminal 2c identified by the number. Due to such a configuration, in the call system 9, the concentration of transfer of incoming calls to the terminal 2 c identified by the duplicate telephone number is suppressed.

  In this modification, the rank of the duplicated terminal 2c added later is lowered, but the rank of the terminal 2c stored previously may be lowered. In short, when there are a plurality of transfer source terminals 2 that request transfer of an incoming call and the transfer destination terminals 2 set by the transfer source terminals 2 overlap each other, the server device 1 As for the use of the duplicated terminal 2 as the transfer destination, any one of the transfer source terminals 2 may be given priority.

2-3. The program executed by the control unit 11 of the program server device 1 is a recording readable by a computer device such as a magnetic recording medium such as a magnetic tape or a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, or a semiconductor memory. It may be provided in a state stored in a medium. It is also possible to download this program via a network such as the Internet. Note that various devices other than the CPU may be applied as the control means exemplified by the control unit 11. For example, a dedicated processor or the like is used.

2-4. Terminal The terminal 2 described above may be a mobile phone, a PDA (Personal Digital Assistant), a portable music player, a portable video player, a game machine, an electronic book browsing device, a navigation device, a personal computer, or the like.

2-5. Telephone number In the above-described embodiment, the telephone number is used as the identification information of the terminal 2, but other identification information may be used. For example, a MAC (Media Access Control) address may be used as identification information unique to each terminal 2. In this case, a correspondence table in which the MAC address is associated with the telephone number of the terminal 2 identified by the MAC address may be stored in the storage unit 12 of the server device 1. Then, when the control unit 11 forms a speech path, the corresponding telephone number may be specified from the MAC address with reference to this correspondence table.

2-6. Positioning The positioning unit 28 of the present invention is not limited to the one based on the GPS positioning method, but may employ other positioning methods. For example, the positioning unit 28 may perform positioning by a base station positioning method. In the base station positioning method, when the base station which is a node of the communication network 3 has the position information of the own station and the terminal 2 becomes communicable with the base station, the position information of the base station is This is a method for acquiring position information. The location information of the base station may be information on latitude and longitude as in the above-described embodiment, but may be information on location such as lot numbers and facility names.

  In the above-described embodiment, when the terminal 2 is a fixed telephone terminal, the positioning unit 28 acquires each position information via the communication network 3 from the server device that stores the position information of each terminal 2 in advance. Also good. The terminal 2 according to the present invention may include a plurality of positioning units having different positioning methods. The terminal 2 according to the present invention may include, for example, a first positioning unit using a base station positioning method and a second positioning unit using a GPS positioning method. In this way, even in a situation where positioning by one positioning unit is not possible, positioning by the other positioning unit may be possible.

2-7. In the above-described embodiment, the specifying unit 114 acquires the position information of each terminal 2 to specify the position of each terminal 2, and the calculation unit 115 is based on each position specified by the specifying unit 114. However, if the distance between the two target terminals 2 is directly acquired, the control unit 11 specifies the position information indicating the position of each terminal 2. It does not have to be.

  FIG. 15 is a diagram showing a functional configuration of the server device 1c in this modification. The server device 1c includes a control unit 11c. The control unit 11c is different from the control unit 11 described above in that a distance specifying unit 114c is provided instead of the specifying unit 114 and the calculating unit 115. The distance specifying unit 114c reads out the telephone number of the terminal 2c that is a transfer destination candidate described in the transfer destination table 110, and also uses the terminal 2 (terminal 2a as a starting point when calculating the distance to the terminal 2c. Alternatively, the telephone number of the terminal 2b) is acquired. And the distance of each terminal 2c and the terminal 2a or the terminal 2b is specified.

  This distance is specified as follows, for example. The distance specifying unit 114c transmits the telephone numbers of the two target terminals 2 to the external device via the communication unit 13, and causes the external device to obtain the distance between the two terminals 2. When the external device acquires the phone numbers of the two terminals 2 from the server device 1, the external device requests the location information indicating the location from the terminal 2 identified by each phone number, and acquires the location information from each terminal 2. Thus, the distance between the terminals 2 is calculated. Then, this external device transmits information indicating the calculated distance to the server device 1. The distance specifying unit 114c specifies the distance between the two terminals 2 by obtaining information on the distance obtained by the external device and transmitted via the communication unit 13.

  Note that the specifying unit 114 and the external device described in this modification in the above-described embodiment request the terminal 2 for the position information of the terminal itself and acquire the position information from each terminal 2. This position information may be acquired by For example, each terminal 2 may measure the position of its own terminal at a predetermined cycle, and the position information of the position measured at each measurement may be transmitted to the server device 1 or an external device. In this case, the server device 1 and the external device acquire the position information without requesting the terminal 2 for the position information.
