  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of a telephone system according to the present invention.

  In this embodiment, as shown in FIG. 1, a calling terminal A101 with a calling number “0001”, a call connection device 201, a receiving terminal B1002 with a called number “1002”, and a called number “1003”. An incoming call terminal C 1003 and an incoming call terminal D 1004 whose incoming call number is “1004” are connected via an IP network 301. Further, a representative group 1001 having a representative incoming call number “1001” of the receiving terminal B 1002, the receiving terminal C 1003, and the receiving terminal D 1004 is provided.

  The calling terminal A 101 is a first communication terminal that is connected to the IP network 301 and performs voice communication and video communication with the receiving terminal B 1002, the receiving terminal C 1003, or the receiving terminal D 1004 via the call connection device 201. Here, for convenience of explanation, the transmission terminal A101 performs transmission, but also has an incoming call function.

  When the call connection device 201 is installed in the IP network 301 and receives a call connection request signal from the calling terminal A 101, the call connection device 201 transmits a call connection request signal to the receiving terminal corresponding to the called number included in the received call connection request signal. And establish communication between terminals.

  The representative group 1001 includes a plurality of receiving terminals (in this embodiment, the receiving terminal B 1002, the receiving terminal C 1003, and the receiving terminal D 1004). When a call is connected to “1001”, which is the representative incoming number of the representative group 1001, one of the incoming terminals in the representative group 1001 is selected to be able to receive a call, and communication is provided. The incoming call terminal is selected by the call connection device 201.

  Receiving terminal B 1002, receiving terminal C 1003, and receiving terminal D 1004 are second communication terminals that are connected to IP network 301 and perform voice communication and video communication with calling terminal A 101 via call connection device 201. In addition, the receiving terminal B 1002, the receiving terminal C 1003, and the receiving terminal D 1004 are a terminal group constituting the representative group 1001. Here, for the convenience of explanation, the receiving terminal B 1002, the receiving terminal C 1003, and the receiving terminal D 1004 perform incoming calls, but also have a calling function.

  Note that the number of receiving terminals constituting the representative group 1001 is not limited to three. In addition, the representative incoming number of the representative group may be any number of the terminal group constituting the representative group.

  FIG. 2 is a diagram illustrating a configuration example of the call connection device 201 illustrated in FIG.

  As shown in FIG. 2, the call connection device 201 shown in FIG. 1 includes a call connection information storage unit 211, a call connection processing unit 212, a timer control unit 213, a terminal information storage unit 214, and a representative group information storage. Part 215 is provided.

  The call connection information storage unit 211 stores (stores) a transmission number and an incoming call number for each communication for which the call connection device 201 performs connection processing.

  FIG. 3 is a diagram illustrating an example of the structure of the call connection information storage unit 211 illustrated in FIG.

  The structure of the call connection information storage unit 211 shown in FIG. 2 is such that a call identification number, a calling number, and a called number are stored in association with each other as shown in FIG. The call identification number is information uniquely assigned to each call in order to identify the call. The calling number is the number of the calling terminal that made the call (for example, a telephone number). The incoming call number is the number (for example, telephone number) of the receiving terminal that has received the incoming call.

  For example, the call identification number “ABCD”, the transmission number “0001”, and the incoming call number “1003” are stored in association with each other. This indicates that the call with the call identification number “ABCD” is a call between the calling terminal having the calling number “0001” and the receiving terminal having the called number “1003”. .

  Further, the call connection processing unit 212 analyzes the call connection request signal transmitted from the calling terminal A101, determines whether or not to connect, and determines the connection destination, and transmits the call connection request signal to the determined connection destination.

  The timer control unit 213 has a timer that is activated by the call connection processing unit 212 to measure time, and notifies the call connection processing unit 212 that the timer has expired when a predetermined time has elapsed.

  FIG. 4 is a flowchart for explaining processing in the timer control unit 213 shown in FIG.

  First, when a timer activation request for activating a timer is received from the call connection processing unit 212 (step S1), the timer is activated (started) (step S2).

  Thereafter, it is determined at any time whether a preset time has elapsed, that is, whether the timer has expired (step S3). If it is determined that the timer has expired, a timer expiration notification indicating that the timer has expired is sent. The call connection processor 212 is notified (step S4).

  The terminal information storage unit 214 stores (stores) a service provided for each terminal number.

  FIG. 5 is a diagram illustrating an example of the structure of the terminal information storage unit 214 illustrated in FIG.

  The terminal information storage unit 214 shown in FIG. 2 has a structure in which a terminal number and provided service information are stored in association with each other as shown in FIG. The terminal number is the incoming number of the incoming terminal, and also includes the representative incoming number of the representative group 1001. The provided service information is information on a service provided to the terminal.

  For example, the terminal number “1001” and the provided service information “representative selection incoming call, representative group 1001” are stored in association with each other. This indicates that the service provided to the terminal whose terminal number is “1001” is the representative selective incoming service of the representative group 1001. This “representative selection incoming call” is to select one incoming call number from among a plurality of incoming call numbers represented by the representative group 1001 when there is an incoming call to the representative group 1001. Further, the terminal number “1002” and the provided service information “transfer service, transfer destination number: 1005” are stored in association with each other. This indicates that the service provided to the terminal having the terminal number “1002” is a transfer service that transfers the incoming call to the terminal number “1002” to the transfer destination number “1005”.

  The representative group information storage unit 215 stores (stores) terminal number information in the representative group 1001.

  FIG. 6 is a diagram showing an example of the structure of the representative group incoming number search data stored in the representative group information storage unit 215 shown in FIG.

  As shown in FIG. 6, the representative group incoming number search data stored in the representative group information storage unit 215 shown in FIG. 2 is associated with representative group identification information, representative incoming number, and incoming number. It has been stored. The representative group identification information is information uniquely assigned to each representative group in order to identify the representative group. The representative call number is the call number of the representative group. These are stored in advance.

  For example, representative group identification information “1001”, representative incoming call number “1001”, incoming call number 1 “1002”, incoming call number 2 “1003”, and incoming call number 3 “1004” are stored in association with each other. Yes. This is because the representative incoming number of the representative group whose representative group identification information is “1001” is “1001”, and the incoming call numbers of the receiving terminals included in this representative group 1001 are “1002”, “1003”, and “1004”. ".

  FIG. 7 is a diagram showing an example of the structure of the representative group priority call number search data stored in the representative group information storage unit 215 shown in FIG.

  As shown in FIG. 7, the representative group priority call number search data stored in the representative group information storage unit 215 shown in FIG. 2 is associated with representative group identification information, calling number, and priority call number. Is stored. The representative group identification information is the same as the representative group identification information of the representative group incoming call number search data shown in FIG. The priority incoming call number is the incoming call number of the receiving terminal that receives the call with priority.

  For example, representative group identification information “1001”, transmission number “0001”, and priority incoming call number “1003” are stored in association with each other. This is because when a call connection is requested from a calling terminal having a calling number “0001” to a representative group (representative called number) having representative group identification information “1001”, the priority connection destination of the call is the called number. Indicates that the receiving terminal is “1003”. Also, representative group identification information “1001”, transmission number “0005”, and priority incoming call number “1004” are stored in association with each other. This is because, when a call connection is requested from a calling terminal having a calling number “0005” to a representative group (representative called number) having representative group identification information “1001”, the priority connection destination of the call is the called number. Indicates that the receiving terminal is “1004”.

  Further, a representative incoming call number may be stored instead of the representative group identification number.

  FIG. 2 shows only the components related to the present invention among the components configuring the call connection device 201.

  FIG. 8 is a diagram showing a configuration example of the receiving terminal C1003 shown in FIG.

  As shown in FIG. 8, the receiving terminal C1003 shown in FIG. 1 is provided with a communication unit 1201, a disconnection detection unit 1202, and a registration signal creation unit 1203.

  The communication unit 1201 has an interface function with the IP network 301.

  The disconnect detection unit 1202 detects the disconnection of communication with the terminal that is communicating with the receiving terminal C 1003 via the communication unit 1201.

  The registration signal creation unit 1203 creates a registration signal for requesting the call connection apparatus 201 to register the correspondence between the transmission number and the incoming number.

  FIG. 8 shows only the components related to the present invention among the components configuring the receiving terminal C1003. Also, the configurations of the receiving terminal B 1002 and the receiving terminal D 1004 shown in FIG. 1 are the same as the configuration of the receiving terminal C 1003 shown in FIG.

  The incoming call selection method in the call connection device 201 shown in FIG. 2 will be described below. First, a process when a call connection request signal is received from the calling terminal A101 shown in FIG. 1 will be described. Here, a case where call connection is requested from the calling terminal A101 to the representative group 1001 will be described as an example.

  FIG. 9 is a flowchart for explaining processing when a call connection request signal is received from calling terminal A 101 shown in FIG. 1 in the incoming call selection method in call connection apparatus 201 shown in FIG.

  First, when a call connection request signal transmitted from the calling terminal A101 is received (step S11), the call connection processing unit 212 responds to the incoming call number based on the incoming call number included in the received call connection request signal. The provided service information is retrieved from the terminal information storage unit 214 (step S12). In this example, the provided service corresponding to the incoming number of the representative group 1001 is searched.

  The provided service information searched in the terminal information storage unit 214 is notified from the terminal information storage unit 214 to the call connection processing unit 212 (step S13). Here, taking the information shown in FIG. 5 as an example, “representative selection incoming call, representative group 1001” is notified.

  Since the notified provided service is “representative selection incoming call”, the representative group identification information is searched from the representative group incoming number search data in the representative group information storage unit 215 based on the incoming call number. Subsequently, based on the transmission number included in the received call connection request signal and the retrieved representative group identification information, the priority incoming call number is searched from the representative group priority incoming call number search data in the representative group information storage unit 215. (Step S14). By this search, it is determined whether or not the priority call number associated with the transmission number and the representative group identification information is registered (step S15). Here, taking the information shown in FIG. 7 as an example, it is determined that the incoming call number “1003” associated with the outgoing call number “0001” and the representative group identification information “1001” is registered as the priority incoming call number. Is done.

  When it is determined that the priority call number associated with the transmission number and the representative group identification information is registered, the call reception number “1003” is notified from the representative group information storage unit 215 to the call connection processing unit 212 ( Step S16).

  Then, a call connection request signal is transmitted from the call connection processing unit 212 to the notified incoming call number “1003” (step S17). Thereafter, it is determined whether or not communication has been established between the calling terminal A101 and the receiving terminal C1003 (step S18). If it is determined that communication has been established, the calling number and the called number are associated with each other and called. It is stored in the call connection information storage unit 211 by the connection processing unit 212 (step S19). Here, a method for determining whether or not communication has been established may be any method that uses a general method, and is not particularly defined here. Thereafter, communication is started between the transmitting terminal A101 and the receiving terminal C1003.

  On the other hand, if it is determined in step S15 that the priority call number associated with the calling number and the representative group identification information is not registered, the call connection processing unit 212 uses the representative group in the representative group information storage unit 215. The incoming call number stored in association with the representative group identification information “1001” is acquired from the incoming call number search data (step S20). Here, taking the information shown in FIG. 6 as an example, incoming numbers “1002”, “1003”, and “1004” are acquired.

  If it is not determined in step S18 that communication has been established, the process of step S20 is performed.

  An arbitrary incoming call number is selected from the acquired incoming call numbers by the call connection processing unit 212, and a call connection request signal is transmitted from the call connection processing unit 212 to the selected incoming call number (step S21). Here, the method for arbitrarily selecting the incoming call number is not particularly defined. A round robin method may be used, a random number table may be used, or a general method may be used. Thereafter, in step S 19, the call number and the incoming number are associated with each other by the call connection processing unit 212 and stored in the call connection information storage unit 211.

  Next, a process when a call disconnection signal is received from the transmitting terminal A101 or the receiving terminal C1003 shown in FIG. 1 after the process described using FIG. 9 will be described.

  FIG. 10 is a flowchart for explaining processing when a call disconnection signal is received from calling terminal A101 or receiving terminal C1003 shown in FIG. 1 in the incoming call selection method in call connection apparatus 201 shown in FIG. .

  When the call disconnection signal transmitted from the calling terminal A101 or the receiving terminal C1003 that is in the call connection is received by the call connection processing unit 212 (step S31), the call is disconnected to the other party that has transmitted the call disconnection signal. A signal is transmitted (step S32). That is, when a call disconnection signal is transmitted from the calling terminal A101, the call disconnection signal is transmitted to the receiving terminal C1003. When a call disconnection signal is transmitted from the receiving terminal C1003, the call disconnection signal is transmitted to the transmitting terminal A101.

  Then, the timer of the timer control unit 213 is started by an instruction from the call connection processing unit 212 (step S33).

  Thereafter, it is determined at any time whether or not a preset time has elapsed, that is, whether or not the timer has expired (step S34). When it is determined that the timer has expired, the call connection processing unit 212 deletes the association between the caller ID of the caller terminal A101 and the caller ID of the caller terminal C1003 stored in the call connection information storage unit 211 (step S35).

  Further, until it is determined that the timer has expired, the call connection processing unit 212 determines whether or not a registration signal has been received (step S36). This registration signal is transmitted from the receiving terminal C1003, and is a signal including the receiving number of the receiving terminal C1003. When the call connection processing unit 212 determines that the registration signal has been received, the call connection processing unit 212 extracts the incoming call number (terminal number) from the received registration signal. Then, the call connection processing unit 212 searches whether the extracted incoming call number is stored in the call connection information storage unit 211 (step S37).

  When the incoming call number extracted from the registration signal is stored in the call connection information storage unit 211 (step S38), the call connection processing unit 212 extracts the outgoing call number from the call connection information storage unit 211, and the outgoing call number And the call reception number are associated with each other and stored (registered) in the representative group priority call number search data of the representative group information storage unit 215 (step S39). At this time, the representative incoming call number representing the incoming call number is searched from the representative group incoming call number search data in the representative group information storage unit 215, and the outgoing call number and the incoming call together with the representative group identification information corresponding to the searched representative incoming call number. A number is stored. The outgoing call number and the incoming call number may be stored together with the representative incoming call number. Further, a response signal indicating that the correspondence between the calling number and the called number can be registered is transmitted from the call connection processing unit 212 to the called terminal C1003 (step S40).

  On the other hand, if the incoming call number extracted from the registration signal is not stored in the call connection information storage unit 211, a response signal indicating that the correspondence between the outgoing call number and the incoming call number cannot be registered is sent to the call connection processing unit 212. To the receiving terminal C1003 (step S41).

  As described above, when a call connection request is received from the same calling terminal by registering the calling number and the called number in the representative group priority called number search data of the representative group information storage unit 215, In the process of step S15 described using the flowchart shown in FIG. Then, a call connection request signal is transmitted to the registered incoming number.

  Hereinafter, a method for creating a registration signal in the receiving terminal C1003 shown in FIG. 8 will be described.

  FIG. 11 is a flowchart for explaining a method of creating a registration signal in receiving terminal C1003 shown in FIG. Here, a case where call connection is requested from the calling terminal A101 via the call connection device 201 will be described as an example.

  First, after a call connection request signal transmitted from the calling terminal A101 via the call connection device 201 is received by the communication unit 1201 (step S51), a response signal corresponding to the call connection request signal from the communication unit 1201. Is transmitted to the calling terminal A101 via the call connection device 201, whereby communication is started between the calling terminal A101 and the receiving terminal C1003 (step S52).

  Thereafter, when the disconnection detection unit 1202 detects that the communication has been disconnected via the communication unit 1201 (step S53), a registration signal generation unit 1203 generates a registration signal (step S54). This registration signal includes information indicating registration and the incoming call number of the receiving terminal C1003. In addition, about a cutting | disconnection detection method, what is necessary is just a general thing, and it does not prescribe | regulate in particular here.

  In addition, it is indicated that the call connection apparatus 201 is instructed to register the incoming call number and the outgoing call number that has been connected until immediately before.

  When the registration signal creation unit 1203 creates a registration signal, the created registration signal is transmitted from the communication unit 1201 to the call connection device 201 (step S55).

  Hereinafter, with respect to the incoming call selection method described above, an operation sequence in the outgoing terminal A 101, the call connection device 201, and the incoming terminal C 1003 will be described. First, a process from when a call connection is requested from the calling terminal A 101 to the call connection apparatus 201 until the caller ID and the incoming call number are registered in the call connection apparatus 201 will be described.

  FIG. 12 shows a method of selecting an incoming call at the calling terminal A 101, the call connection device 201, and the receiving terminal C 1003. The call number and the called number are called after the call connection from the calling terminal A 101 to the call connection device 201 is requested. FIG. 6 is a sequence diagram for explaining processing until registration in a connection apparatus 201.

  When a call connection request signal to the representative group 1001 is transmitted from the calling terminal A101 to the call connection device 201 (step S61), the representative selection is performed based on the content stored in the terminal information storage unit 214 by the call connection processing unit 212. The incoming call is activated (step S62). This is because the terminal information storage unit 214 is searched for the incoming call number included in the call connection request signal transmitted from the caller terminal A101, thereby recognizing that the incoming call signal is a representative selection incoming call. Is due to being done.

  Then, the call connection processing unit 212 selects the incoming call number associated with the incoming call signal and stored in the representative group information storage unit 215 (step S63). A call connection request signal is transmitted to the called terminal (in this case, called terminal C1003) of the selected called number (step S64), and a response is transmitted from the called terminal C1003 to the calling terminal A101 via the call connection device 201 ( Step S65). Thereby, communication is performed between the transmitting terminal A101 and the receiving terminal C1003. At this time, the processing at step S52 described using the flowchart shown in FIG. 11 is performed at the receiving terminal C1003.

  Thereafter, when a call disconnection signal is transmitted from the calling terminal A101 to the receiving terminal C1003 via the call connection device 201 (step S66), a response is transmitted from the receiving terminal C1003 to the calling terminal A101 via the call connection device 201. (Step S67).

  Then, the timer of the timer control unit 213 is started by the call connection processing unit 212 of the call connection device 201 (step S68).

  When the call disconnection signal is received by the receiving terminal C1003 after the process of step S66, the receiving terminal C1003 performs the processes of steps S55 and S56 described with reference to the flowchart shown in FIG. Then, a registration signal is transmitted from the receiving terminal C1003 to the call connection device 201 (step S69).

  When the registration signal transmitted from the terminating terminal C1003 is received by the call connection device 201, the incoming number included in the registration signal and the transmission number associated with the information in the call connection information storage unit 211 are call-connected. The information is stored (registered) in the representative group priority call number search data of the representative group information storage unit 215 in association with the processing unit 212 (step S70). At this time, the incoming call number is stored as a priority incoming call number. Specifically, the process of step S70 is the process of steps S37 to S39 described using the flowchart shown in FIG. Then, a response signal indicating that the correspondence between the calling number and the called number can be registered is transmitted from the call connection processing unit 212 to the receiving terminal C1003 (step S71).

  In the following, a process when a call connection is requested again from the calling terminal A 101 to the call connection device 201 after the transmission number and the called number are registered in the call connection device 201 as described above will be described.

  FIG. 13 shows a method of selecting an incoming call at the calling terminal A 101, the call connection device 201, and the receiving terminal C 1003. It is a sequence diagram for demonstrating a process when a call connection is requested | required again.

  When a call connection request signal to the representative group 1001 is transmitted from the calling terminal A101 to the call connection device 201 (step S81), the representative selection is performed based on the content stored in the terminal information storage unit 214 by the call connection processing unit 212. The incoming call is activated (step S82). This is because the terminal information storage unit 214 is searched for the incoming call number included in the call connection request signal transmitted from the caller terminal A101, thereby recognizing that the incoming call signal is a representative selection incoming call. Is due to being done.

  Then, the call connection processing unit 212 extracts the priority call number from the intra-representative group priority call number search data associated with the incoming call signal and stored in the representative group information storage unit 215 (step S83). The specific process of step S83 is the process of steps S12 to S16 described using the flowchart shown in FIG. A call connection request signal is transmitted to the called terminal of the extracted called number (in this case, called terminal C1003) (step S84), and a response is sent from the called terminal C1003 to the calling terminal A101 via the call connection device 201 ( Step S85). Thereby, communication is performed between the transmitting terminal A101 and the receiving terminal C1003.

  In this way, a call connection is requested to the call connection device from the calling terminal to which the calling number is given to the representative called number that represents the called number assigned to each of the plurality of receiving terminals. After the communication is started and completed between the receiving terminal assigned with one incoming number selected by the call connection device and the outgoing terminal, the incoming call terminal is connected to the call connection device from the incoming terminal to immediately before. Registration in association with the outgoing number is required. Then, the call connection device stores (registers) the transmission number and the incoming call number in association with each other. Thereafter, when the call connection from the calling terminal to the representative called number is requested again, the called number associated with the calling number assigned to the calling terminal based on the association stored in the call connecting device. Call connection is requested from the call connection device to the receiving terminal to which is given. Therefore, for communication between the calling terminal registered from the receiving terminal and the receiving terminal, if there is a call connection request from the calling terminal to the representative called number, a specific incoming call is made directly without performing representative selection. The terminal can be called. In addition, when a specific incoming terminal cannot be received, it is possible to improve the incoming call completion rate by performing representative selection.
