[Configuration example of telephone control device 1]
FIG. 2 is a block diagram for explaining a configuration example of the telephone control device 1. The communication I / F 101 is a part that performs communication processing through the communication network 5. That is, the communication I / F 101 converts the signal addressed to the own machine transmitted via the communication network 5 into a signal in a format that can be processed by the own machine, and captures the signal. Further, the communication I / F (Interface) 101 converts a signal transmitted from its own device to a target destination, converts it into a signal in a transmission format, sends it to the communication network 5, and transmits it to the destination. ..

Although not shown, the control unit 102 is a microprocessor including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a non-volatile memory, and the like, and controls each part of the telephone control device 1. .. The storage device 103 includes, for example, a storage device such as a hard disk and a driver thereof, and writes, reads, changes, deletes, and the like data to the storage device. The storage device 103 records various application programs, data required for processing, and the like, and is also used as a work area for temporarily storing the intermediate results of processing.

The address management DB (Date Base) 104 stores and holds address information and other management information about the fixed-line telephone terminal and the mobile phone terminal housed in the own machine. FIG. 3 is a diagram for explaining an example of stored data of the address management DB 104. As shown in FIG. 3, the address management DB 104 includes an "extension number", a "type", and an "IP (Internet Protocol) address" for each fixed telephone terminal or mobile phone terminal accommodated in the telephone control device 1. , "Mobile phone number", "Group master unit", "Pairing information (described as pairing in FIG. 3)", "Usage status", and "Other" information are stored and retained.

The "extension number" is a number for an extension telephone assigned to all telephone terminals accommodated in the telephone control device 1. The "type" is information indicating either a "fixed telephone terminal" or a "mobile phone terminal" added to all the telephone terminals accommodated in the telephone control device 1. An IP address is assigned to a device that can connect to the Internet, such as an IP phone terminal or a mobile phone terminal, by, for example, a DHCP (Dynamic Host Configuration Protocol) server, and each of the IP phone terminal or the mobile phone terminal is uniquely identified. Information that can be done. In this embodiment, the fixed telephone terminal housed in the telephone control device 1 will be described as, for example, an IP telephone terminal.

The "mobile phone number" is a telephone number assigned to a mobile phone terminal to be accommodated in the telephone control device 1. The mobile phone terminal accommodated in the telephone control device 1 is installed with the above-mentioned cooperation application so that it can function as an extension telephone housed in the telephone control device 1 in cooperation with the telephone control device 1. It means a mobile phone terminal that has been used.

The "group master unit" is an extension number of a fixed telephone terminal associated with a mobile phone terminal to be accommodated in the telephone control device 1. The "pairing information" is "ON" in the case of a mobile phone terminal existing in the vicinity of the associated fixed-line telephone terminal, and is "ON" in the case of a mobile phone terminal not existing in the vicinity of the associated fixed-line telephone terminal. Is information that is "OFF". Therefore, if the "pairing information" is "ON", it can be determined that the user of the mobile phone terminal is "attended", and conversely, if it is "OFF", it can be determined that the user is "absent".

The "use state" is information that is "1" if it is in use and "0" if it is not in use for all the telephone terminals accommodated in the telephone control device 1. For example, if it is in the off-hook state, is calling in response to an incoming call, or is in a call, it is determined that it is in use, and it is in the on-hook state and is not being called in response to an incoming call. Is determined to be unused. Then, as "others", it is possible to add various necessary information such as a port number, a MAC address (Media Access Control address) of each telephone terminal, and a URL (Uniform Resource Locator).

From the stored data of the address management DB 104, the telephone control device 1 can grasp what each telephone terminal accommodated in its own unit is and manage its state. Therefore, if a telephone terminal is connected to the telephone control device 1, management data for the connected telephone terminal is added. Further, if the telephone terminal connected to the telephone control device 1 is removed, basically, the management data for the removed telephone terminal is deleted.

The connection I / F (Interface) 105 is connected to a fixed telephone terminal accommodated in the telephone control device 1 and enables communication between the telephone control device 1 and the fixed telephone terminal. Therefore, the signal from the telephone control device 1 to each fixed telephone terminal is converted into a signal in the form for transmission at the connection I / F 105 and transmitted to each fixed telephone terminal. Further, the signal from each fixed telephone terminal is converted into a signal in a format that can be processed by the own machine at the connection I / F 105 and is taken in.

In this embodiment, as shown in FIG. 1, each of the fixed telephone terminals 2 (1), 2 (2), 2 (3), ... Is connected to the telephone control device 1 through the connection I / F 105 by wire. Be connected. Further, the fixed telephone terminals 3 (1), ... Are wirelessly connected to the telephone control device 1 through the access point AP (1), ... Connected to the connection I / F 105. Communication with the mobile phone terminal accommodated in the telephone control device 1 is performed through a communication network such as the Internet or a mobile phone network, as described above. Therefore, communication with the mobile phone terminal accommodated in the telephone control device 1 is performed via the communication I / F 101.

The pairing processing unit 111 updates the "pairing information" of the address management DB 104 based on the pairing registration data described later which is sequentially transmitted from the fixed telephone terminals 2 and 3 connected through the connection I / F 105. Perform the processing to be performed. That is, when the fixed telephone terminals 2 and 3 are in a state where data can be transmitted and received by short-range wireless communication with the associated mobile phone terminal 4, the fixed telephone terminals 2 and 3 form pairing registration data to control the telephone. It is transmitted to the device 1. Further, the fixed telephone terminals 2 and 3 do not transmit the pairing registration data when the data cannot be transmitted / received to / from the associated mobile phone terminal 4 by short-range wireless communication. The pairing processing unit 111 updates and manages this state in the address management DB 104, thereby managing the presence / absence of the user of the mobile phone terminal 4.

Specifically, the pairing processing unit 111 sets the "pairing information" to "ON" when the pairing registration data for the mobile phone terminal 4 whose "pairing information" is "OFF" is transmitted. .. Then, the pairing processing unit 111 maintains "ON" of the "pairing information" while the pairing registration data is transmitted at predetermined timings. In this way, the mobile phone terminal 4 in which the "pairing information" of the address management DB 104 is "ON" is paired (or is in a pairing state) with the associated fixed-line telephone terminal. That is.

Further, when the pairing registration data for the mobile phone terminal 4 whose "pairing information" is "ON" is not transmitted for a predetermined time or more (for example, 1 minute or more), the pairing processing unit 111 of the address management DB 104 Turn off pairing. Then, the "OFF" state of the "pairing information" is maintained until the pairing registration data is transmitted. As described above, the mobile phone terminal 4 in which the "pairing information" of the address management DB 104 is "OFF" is not paired with the associated fixed-line telephone terminal (or is in the unpaired state). That is.

The call control unit 112 uses the management information of the address management DB 104 to control outgoing calls, incoming calls, answers, and disconnections between the fixed telephone terminals 2 and 3 and the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3. I do. That is, the call control unit 112 receives an incoming call addressed to the fixed telephone terminals 2 and 3, notifies the fixed telephone terminals 2 and 3 of the incoming call, and when the user of the fixed telephone terminal performs an answering operation, the call line. Connect to enable calls. Further, the call control unit 112 receives the outgoing call request from the fixed telephone terminals 2 and 3 and calls the other party, and when the other party answers, the call line is connected to enable the call. Incoming / outgoing calls in this case include both internal and external lines.

Similarly, incoming call processing and outgoing call processing for the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3 are also performed. In this case, as described above, the telephone control device 1 and the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3 exchange control information via the Internet, and the call is made through the mobile phone network. Connect the line so that you can make a call. Further, the call control unit 112 controls the display on the display unit of the fixed telephone terminals 2 and 3 housed in the own unit and the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3, and the LED (Light Emitting Diode). It also controls the lighting / extinguishing of.

Further, the call control unit 112 updates the usage status of the fixed telephone terminals 2 and 3 housed in the own unit and the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3 to the address management DB 104. I do. That is, when the fixed telephone terminals 2 and 3 are in the off-hook state or when there is an incoming call and the call is being made, it is determined that the fixed telephone terminals 2 and 3 are in use, and the use state of the address management DB 104 is set to "1". The off-hook state includes a case where a call is being made or a call is being made to the other party.

Further, when the address management DB 104 is in the on-hook state and is not being called in response to an incoming call, the usage state of the address management DB 104 is set to "0". Similarly, the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3 is also determined to be in use when it is in the off-hook state or when there is an incoming call and is calling, and the address management DB 104 is used. Set the state to "1". Further, the mobile phone terminal 4 paired with the fixed telephone terminals 2 and 3 is also in the on-hook state, and when the call is not being made in response to an incoming call, the usage state of the address management DB 104 is set to "0".

Then, the call control unit 112 cooperates with the use / non-use determination unit 113 and the presence / absence determination unit 114 to receive an incoming call addressed to the paired mobile phone terminal 4 from the fixed telephone terminal 2. 3 is used preferentially so that it can respond. That is, when the telephone control device 1 receives an incoming call addressed to the paired mobile phone terminal 4, the control unit 102 first controls the use / non-use determination unit 113 to be the initial destination. It is determined whether the fixed telephone terminals 2 and 3 to which the mobile phone terminal 4 is associated are in use or not. The use / non-use determination unit 113 refers to the "use state" of the fixed telephone terminals 2 and 3 associated with the destination mobile phone terminal 4 of the address management DB 104, and is used by the fixed telephone terminals 2 and 3. Determine if it is medium or not.

When the use / non-use determination unit 113 determines that the fixed telephone terminals 2 and 3 are not in use, the control unit 102 controls the presence / absence determination unit 114 to perform the initial call destination. Let the user of the mobile phone terminal 4 determine whether he / she is present or absent. The presence / absence determination unit 114 refers to the "pairing information" of the mobile phone terminal 4 of the initial destination of the address management DB 104, and determines whether or not the user of the mobile phone terminal 4 is present. ..

It is assumed that the user of the mobile phone terminal 4 is determined to be present by the presence / absence determination unit 114. That is, it is assumed that the fixed telephone terminals 2 and 3 associated with the mobile phone terminal 4 of the initial destination are not used, and it is determined that the user of the original mobile phone terminal 4 is present. In this case, the control unit 102 controls the call control unit 112 to notify the fixed telephone terminals 2 and 3 associated with the mobile phone terminal 4 of an incoming call to the mobile phone terminal 4. As a result, an incoming call to the mobile phone terminal 4 can be answered through the associated fixed-line telephone terminals 2 and 3.

Further, the call control unit 112 notifies the associated fixed-line telephone terminals 2 and 3 of an incoming call addressed to the mobile phone terminal 4, and when the fixed-line telephone terminals 2 and 3 are in use, the fixed-line telephone terminals 2 and 3 are in use. When an incoming call addressed to the telephone terminals 2 and 3 is received, the caller is controlled to notify that the call is in use. That is, even when an incoming call addressed to the mobile phone terminal 4 is transferred and the fixed-line telephone terminal is in use, the other party is notified that the call is in use.

Further, it is assumed that the use / non-use determination unit 113 determines that the fixed telephone terminals 2 and 3 to which the mobile phone terminal 4 which is the initial destination is associated is in use. In this case, the call control unit 112 notifies the mobile phone terminal 4 of the incoming call to the mobile phone terminal 4 as it is, regardless of whether or not the associated mobile phone terminal 4 is present.

Further, it is assumed that the user of the mobile phone terminal 4 is determined to be absent by the presence / absence determination unit 114. Also in this case, the call control unit 112 notifies the mobile phone terminal 4 of the incoming call to the mobile phone terminal 4 as it is, regardless of whether or not the associated fixed-line telephone terminal is in use.

In this way, under the control of the control unit 102, the pairing processing unit 111, the call control unit 112, the use / non-use determination unit 113, and the presence / absence determination unit 114 act and function. As a result, it is possible to preferentially use the fixed telephone terminals 2 and 3 to which the mobile phone terminal 4 is associated to answer an incoming call addressed to the paired mobile phone terminal 4.

The short-range wireless communication unit 209 and the short-range wireless communication antenna 209A are parts that realize short-range wireless communication of the Bluetooth (registered trademark) standard in this embodiment. Then, the pairing processing unit 210 is paired when it is in a situation where it can communicate with the mobile phone terminal 4 associated with its own device through the short-range wireless communication unit 209 and the short-range wireless communication antenna 209A. The process of forming the registration data and providing it to the telephone control device 1 is performed.

In this embodiment, in the fixed telephone terminals 2 and 3, for example, identification information such as a telephone number of a mobile phone terminal associated with the own unit is registered in advance in a predetermined internal memory (not shown). Then, the pairing processing unit 210 performs short-range wireless communication through the short-range wireless communication unit 209 and the short-range wireless communication antenna 209A, so that the mobile phone terminal 4 associated with the own device is associated with the own unit at predetermined timings. It is assumed that the identification information from is obtained.

In this case, the pairing processing unit 210 forms pairing registration data at predetermined timings and provides the pairing registration data to the telephone control device 1. The predetermined timing may be the timing at which the identification information is acquired from the associated mobile phone terminal 4, or may be a timing different from that. For example, if the identification information from the associated mobile phone terminal 4 is acquired twice, a pairing registration request can be formed and provided to the telephone control device 1.

The pairing processing unit 210 may also record and manage the pairing state with the mobile phone terminal 4 associated with the own device in the non-volatile memory of the control unit 220, for example. .. As a result, when the identification information of the mobile phone terminal 4 is no longer transmitted from the mobile phone terminal 4 in the paired state, pairing deletion data is formed and provided to the telephone control device 1. Can be done. In this case, the telephone control device 1 can control the pairing registration process when the pairing registration data is transmitted and the pairing deletion process when the pairing deletion data is transmitted. ..

As described above, the fixed telephone terminals 2 and 3 can receive and make a telephone call through the telephone control device 1. Further, when the fixed-line telephone terminals 2 and 3 are in a state where short-range wireless communication is possible with the mobile phone terminal 4 associated with the own device, the fixed-line telephone terminals 2 and 3 form pairing registration data and perform the pairing registration process. It is something that can be done.

When the fixed-line telephone terminals 2 and 3 cannot perform short-range wireless communication with the mobile phone terminal 4 associated with the own device, the fixed-line telephone terminals 2 and 3 stop the process of forming and transmitting the pairing registration data. Therefore, in the telephone control device 1, the pairing registration data is provided at predetermined timings, but when the pairing registration data is not provided, it is determined that the mobile phone terminal 4 is separated from the fixed telephone terminals 2 and 3, and the pair is paired. The ring can be released.

Further, the fixed telephone terminals 2 and 3 form pairing registration data regardless of whether or not they are associated with the own unit when there is a mobile phone terminal 4 capable of short-range wireless communication with the own unit. It may be provided to the telephone control device 1. In this case, in the telephone control device 1, it is determined by referring to the stored data of the address management DB 104 whether or not the fixed telephone terminals 2 and 3 of the transmission source and the mobile phone terminal 4 have a corresponding relationship. Then, when there is a correspondence relationship, the pairing information about the mobile phone terminal 4 may be set to "ON".

[Operation of the telephone system centered on the telephone control device 1]
7 and 8 are sequence diagrams for explaining the operation of the telephone system of this embodiment centered on the telephone control device 1. FIG. 9 is a diagram for explaining changes in the main data of the address management DB 104 in the processes shown in FIGS. 7 and 8. Here, there are fixed telephone terminals 2 (1), 2 (2), and 2 (3) that are wiredly connected to the telephone control device 1, and the mobile telephone terminal 4 is connected to the fixed telephone terminal 2 (3). The case where (1) and 4 (2) are associated with each other will be described as an example. Then, in the following, for the sake of simplicity, the case of making an extension call from the fixed telephone terminal 2 to the mobile phone terminal 4 will be described as an example, but when an outside line incoming call with an extension number is generated occurs. Is the same process.

First, it is assumed that short-range wireless communication is possible between the fixed-line telephone terminal 2 (3) and the mobile phone terminal 4 (1) associated with the fixed-line telephone terminal 2 (3). In this case, the mobile phone terminal 4 (1) transmits a pairing request including the mobile phone number as the identification information of the own device from the mobile phone terminal 4 (1) to the fixed telephone terminal 2 (3) by the function of the cooperation application. (Step S1). When the pairing processing unit 210 of the fixed telephone terminal 2 (3) receives the pairing request from the mobile phone terminal 4 (1) associated with the own device, the pairing processing unit 210 forms pairing registration data and pairs the pairing registration data. It is transmitted to the telephone control device 1 as a ring registration request (step S2).

Then, it is assumed that the telephone control device 1 receives the pairing registration data from the fixed telephone terminal 2 (3). In this case, the pairing processing unit 111 of the telephone control device 1 functions, and the pairing information of the stored data for the mobile phone terminal 4 (1) associated with the fixed telephone terminal 2 (3) of the address management DB 104. Is set to "ON" (step S3). As a result, the mobile phone terminal 4 (1) is paired with the fixed telephone terminal 2 (3) (pairing state).

After that, an extension call is made from the fixed telephone terminal 2 (1) to which the extension number "101" is assigned to the mobile phone terminal 4 (1) to which the extension number "501" is assigned. Suppose (step S4). In this case, the call control unit 112 of the telephone control device 1 performs a determination process for determining the called destination (step S5).

The determination process in step S5 is performed based on the stored data of the address management DB 104. Specifically, (1) the call control unit 112 refers to the stored data of the address management DB 104, and confirms the fixed telephone terminals 2 and 3 to which the destination mobile phone terminal 4 (1) is associated. Then, (2) when there are the associated fixed telephone terminals 2 and 3, the call control unit 112 controls the use / non-use determination unit 113 to control the associated fixed telephone terminal 2 and 3. Judge the use / non-use of 3. Further, (3) the call control unit 112 controls the presence / absence determination unit 114 to determine whether or not the user of the destination mobile phone terminal 4 (1) is present.

In the case of this example, since the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (1) is associated is not in use (in an unused state), the fixed-line telephone terminal 2 (3) of the address management DB 104 ) Corresponds to the usage state of the stored data is "0". Therefore, it can be determined that the fixed telephone terminal 2 (3) is in an unused state. Further, by the processing of steps S1 to S3 described above, the pairing information of the stored data for the mobile phone terminal 4 (1) is turned "ON" in the address management DB 104 of the telephone control device 1. Therefore, it can be determined that the user of the mobile phone terminal 4 (1) is present.

In this way, it is determined that the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (1) to which the extension telephone is received is associated is in an unused state, and the mobile phone terminal 4 (1) is used. It is assumed that a person is present. In this case, the call control unit 112 does not notify the mobile phone terminal 4 (1), which is the original destination, of the incoming call, but the extension number to which the mobile phone terminal 4 (1) is associated is "103". Notify the fixed-line telephone terminal 2 (3) of the incoming call (step S6). That is, the call control unit 112 can transfer the called destination based on the determination result of the use / non-use determination unit 113 and the determination result of the presence / absence determination unit 114. In other words, an incoming call to the mobile phone terminal 4 (1) can be temporarily answered using the fixed telephone terminal 2 (3).

If there is no fixed-line telephone terminal to which the mobile phone terminal 4 (1) is associated, or if the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (1) is associated is in use, the mobile phone The terminal 4 (1) may not be paired with the fixed telephone terminal 2 (3). In these cases, the extension call to the mobile phone terminal 4 (1) is notified to the mobile phone terminal 4 (1).

Then, the fixed-line telephone terminal 2 (3) to which the extension call to the mobile phone terminal 4 (1) is transferred rings in response to the incoming call notification (step S7) to notify the user of the incoming call. In this case, the user of the mobile phone terminal 4 (1) should be present at his / her own seat, so that the user of the mobile phone terminal 4 (1) performs a response operation (step S8). .. As a result, the control unit 220 of the fixed-line telephone terminal 2 (3) returns the incoming call response to the telephone control device 1, so that the call control unit 112 of the telephone control device 1 receives an incoming call from the fixed-line telephone terminal 2 (1) of the caller. A telephone line is connected to the fixed telephone terminal 2 (3), and a telephone call is started (step S9). Further, the call control unit 112 registers "1" indicating that the stored data of the fixed telephone terminal 2 (1) and the fixed telephone terminal 2 (3) of the address management DB 104 are in use (step S10).

After that, when the call is completed and either the fixed telephone terminal 2 (1) or the fixed telephone terminal 2 (3) performs an on-hook operation, the connected call line is disconnected and the call ends (step S11). After that, the call control unit 112 registers "0" indicating non-use in the usage status of the stored data for the fixed telephone terminal 2 (1) and the fixed telephone terminal 2 (3) of the address management DB 104 (step S12). ).

At this point, as shown in FIG. 9A, it can be seen that only the mobile phone terminal 4 (1) having the extension number "501" is paired with the fixed telephone terminal 2 (3). Further, all of the "usage states" of the fixed-line telephone terminals 2 (1), 2 (2), 2 (3) and the mobile phone terminals 4 (1) and 4 (2) are set to "0". , It can be understood that all the telephone terminals are in an unused state.

After that, it is assumed that the process shown in FIG. 8 proceeds to enable short-range wireless communication between the fixed telephone terminal 2 (3) and the mobile phone terminal 4 (2) associated with the fixed telephone terminal 2 (3). In this case, the mobile phone terminal 4 (2) transmits a pairing request including the mobile phone number as the identification information of the own device from the mobile phone terminal 4 (2) to the fixed telephone terminal 2 (3) by the function of the cooperation application. (Step S21). When the pairing processing unit 210 of the fixed telephone terminal 2 (3) receives the pairing request from the mobile phone terminal 4 (2) associated with the own device, the pairing processing unit 210 forms pairing registration data and pairs the pairing registration data. It is transmitted to the telephone control device 1 as a ring registration request (step S22).

Then, it is assumed that the telephone control device 1 receives the pairing registration data from the fixed telephone terminal 2 (3). In this case, the pairing processing unit 111 of the telephone control device 1 functions, and the pairing information of the stored data for the mobile phone terminal 4 (2) associated with the fixed telephone terminal 2 (3) of the address management DB 104. Is set to "ON" (step S23). As a result, in addition to the mobile phone terminal 4 (1), the mobile phone terminal 4 (2) is also paired with the fixed telephone terminal 2 (3) (pairing state).

After that, an extension call is made again from the fixed telephone terminal 2 (1) to which the extension number "101" is assigned to the mobile phone terminal 4 (1) to which the extension number "501" is assigned. It is assumed that it has been performed (step S24). In this case, the call control unit 112 of the telephone control device 1 performs a determination process for determining the called destination (step S25). The determination process in step S25 is the same as the determination process in step S5 described above. In this case, as shown in FIG. 9A, the "usage state" of the fixed-line telephone terminal 2 (3) associated with the mobile phone terminal 4 (1) is "0", and it is determined that the mobile phone terminal 2 (3) is not in use. can. Further, the "pairing information" of the mobile phone terminal 4 (1) is "ON", and since it is paired with the fixed telephone terminal 2 (3), the user of the mobile phone terminal 4 (1) is present. Can be judged.

In this way, it is determined that the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (1) to which the extension telephone is received is associated is in an unused state, and the mobile phone terminal 4 (1) is used. It is assumed that a person is present. In this case, the call control unit 112 does not notify the mobile phone terminal 4 (1), which is the original destination, of the incoming call, but the extension number to which the mobile phone terminal 4 (1) is associated is "103". Notify the fixed-line telephone terminal 2 (2) of the incoming call (step S26). That is, the call control unit 112 sends a call destination to the mobile phone terminal 4 (1) based on the determination result of the use / non-use determination unit 113 and the determination result of the presence / absence determination unit 114. Transfer to 2 (3).

Then, the fixed-line telephone terminal 2 (3) to which the extension call to the mobile phone terminal 4 (1) is transferred rings in response to the incoming call notification (step S27) to notify the user of the incoming call. In this case, the user of the mobile phone terminal 4 (1) should be present at his / her own seat, so that the user of the mobile phone terminal 4 (1) performs a response operation (step S28). .. As a result, the call control unit 112 of the telephone control device 1 connects a call line between the fixed-line telephone terminal 2 (1) of the call source and the fixed-line telephone terminal 2 (3) of the call destination, and starts a call ( Step S29). Further, the call control unit 112 registers "1" indicating that the stored data of the fixed telephone terminal 2 (1) and the fixed telephone terminal 2 (3) of the address management DB 104 are in use (step S30).

At this point, as shown in FIG. 9B, the mobile phone terminal 4 (1) having the extension number "501" and the mobile phone terminal 4 (2) having the extension number "502" are fixed telephone terminals. It can be grasped that it is paired with 2 (3). Further, the fixed telephone terminal 2 (1) and the fixed telephone terminal 2 (3) have a "use state" of "1", and it can be grasped that these are "in use". Further, both the "usage state" of the fixed-line telephone terminal 2 (2) and the mobile phone terminals 4 (1) and 4 (2) are set to "0", and these are "non-used". I can grasp it.

After that, an extension call is made from the fixed telephone terminal 2 (2) to which the extension number "102" is assigned to the mobile phone terminal 4 (2) to which the extension number "502" is assigned. (Step S31). In this case, the call control unit 112 of the telephone control device 1 performs a determination process for determining the called destination (step S32). The determination process in step S32 is the same as the determination process in steps S5 and S25.

In the case of this example, as shown in FIG. 9 (B), in the address management DB 104, the “usage state” of the stored data for the fixed telephone terminal 2 (3) to which the mobile phone terminal 4 (2) is associated. Is "1". Therefore, it can be determined that the fixed telephone terminal 2 (3) is in use. Further, by the processing of steps S21 to S23 described above, the pairing information of the stored data for the mobile phone terminal 4 (2) is turned "ON" in the address management DB 104 of the telephone control device 1. Therefore, it can be determined that the user of the mobile phone terminal 4 (2) is present.

In this way, it is assumed that the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (2) to which the extension telephone is received is associated is determined to be in use. In this case, the call control unit 112 notifies the mobile phone terminal 4 (2), which is the original destination of the call whose extension number is "502", of the incoming call (step S33). That is, when it is determined that the fixed-line telephone terminal 2 (3) to which the mobile phone terminal 4 (2) to which the extension telephone is received is associated is in use, for example, the mobile phone terminal 4 (2) ), Even if it can be determined that the user is present, the mobile phone terminal 4 (2) is notified of the incoming call. This is because the fixed-line telephone terminal 2 (3) is in use and cannot notify an incoming call.

Then, the mobile phone terminal 4 (2) rings in response to the incoming call notification (step S34) to notify the user of the incoming call. The user of the mobile phone terminal 4 (2) performs a response operation to the mobile phone terminal 4 (2) (step S35). As a result, the control unit 410 of the mobile phone terminal 4 (2) returns the incoming call response to the telephone control device 1, so that the call control unit 112 of the telephone control device 1 receives an incoming call with the caller's fixed telephone terminal 2 (2). A call line is connected to the mobile phone terminal 4 (2) above, and a call is started (step S36). Further, the call control unit 112 registers "1" indicating that the stored data of the fixed telephone terminal 2 (2) and the mobile telephone terminal 4 (2) of the address management DB 104 are in use (step S37).

At this point, as shown in FIG. 9C, the mobile phone terminal 4 (1) having the extension number "501" and the mobile phone terminal 4 (2) having the extension number "502" are fixed telephone terminals. It can be grasped that it is paired with 2 (3). Further, the fixed-line telephone terminal 2 (1), the fixed-line telephone terminal 2 (3), and the mobile phone terminal 4 (2) have a "use state" of "1", and these can be grasped as "in use". Further, the "usage state" of the mobile phone terminal 4 (1) is "0", and it can be grasped that only the mobile phone terminal 4 (1) is "not used".

In this way, when the user of the mobile phone terminal 4 (1) or the mobile phone terminal 4 (2) is present, the incoming call to the mobile phone terminal 4 (1) or the mobile phone terminal 4 (2) is received. If the fixed-line telephone terminal 2 (3) is not used, it is transferred to the fixed-line telephone terminal 2 (3). In this case, when the fixed telephone terminal 2 (3) is used to answer the incoming call, the fixed telephone terminal 2 (3) is in use, and even if the fixed telephone terminal 2 (3) receives an incoming call, the caller is notified. You will be notified that it is in use.

Further, even when the users of the mobile phone terminal 4 (1) and the mobile phone terminal 4 (2) are present, when the fixed telephone terminal 2 (3) is in use, the mobile phone terminal 4 (1), the incoming call to the mobile phone terminal 4 (2) is notified to the called party as it is. Further, when the users of the mobile phone terminals 4 (1) and 4 (2) are absent, the mobile phone terminals 4 (1) and 4 (2) are not used even if the fixed telephone terminal 2 (3) is not used. ) Can not be answered through the fixed telephone terminal 2 (3). In this case as well, the incoming call to the mobile phone terminals 4 (1) and 4 (2) is notified to the mobile phone terminals 4 (1) and 4 (2) as it is.

In this way, the use of the mobile phone terminals 4 (1) and 4 (2) cannot be answered through the fixed telephone terminal 2 (1) to which the mobile phone terminals 4 (1) and 4 (2) are associated. Suppose it is in. In this case, the incoming call to the mobile phone terminals 4 (1) and 4 (2) is notified to the mobile phone terminals 4 (1) and 4 (2) as they are. Therefore, the incoming call to the mobile phone terminal 4 (1) or the mobile phone terminal 4 (2) may be in use by the fixed telephone terminal 2 (3) or may not be paired with the fixed telephone terminal 2 (1). You will not be notified to do so. Therefore, the situation that the incoming call to the mobile phone terminals 4 (1) and 4 (2) cannot be answered does not occur.

[Other examples of pairing]

The fixed-line telephone terminals 2 and 3 register pairing with the telephone control device 1 when they can communicate with each other by short-range wireless communication. However, it is not limited to this. For example, the pairing can be registered for the telephone control device 1 through a personal computer connected to the LAN.

FIG. 10 is a diagram for explaining the overall configuration of another telephone system configured by using the telephone control device 1. In the telephone system shown in FIG. 10, the same reference is given to a portion configured in the same manner as the telephone system shown in FIG. 1, and the description of that portion will be omitted because it will be duplicated. However, in the telephone system shown in FIG. 10, the fixed telephone terminals 2 (1), 2 (2), 2 (3), ... And the mobile telephone terminals 4 (1) and 4 (2) are all short-range wireless. It is assumed that it does not have a communication function.

Then, in the case of the telephone system shown in FIG. 10, user PCs (Personal Computers) 6 (1), 6 (2), ..., 6 (n) are LANs (Local Area Network) with respect to the telephone control device 1. It is connected. Then, each of the user PCs 6 (1), 6 (2), ..., 6 (n) can connect to the Internet through the telephone control device 1 to browse Web pages and send / receive e-mails. ing.

Each of the user PCs 6 (1), 6 (2), ..., 6 (n) is fixedly arranged and used on the desk of the office of the company. In this example, the user PC 6 (1) is for the user of the mobile phone terminal 4 (1), and the user PC 6 (2) is for the user of the mobile phone terminal 4 (2). do. Further, also in this example, it is assumed that the mobile phone terminal 4 (1) and the mobile phone terminal 4 (2) are associated with the fixed telephone terminal 2 (3). Therefore, the user PCs 6 (1) and 6 (2) are arranged in the vicinity of the fixed telephone terminal 2 (3).

Then, when the user of the mobile phone terminal 4 (1) is at his / her own seat in the company, the mobile phone terminal 4 (1) is connected to the user PC 6 (1) through, for example, a USB (Universal Serial Bus) cable 7 (1). Then, it will be possible to charge and transfer data. Similarly, when the user of the mobile phone terminal 4 (2) is at his / her own seat in the company, the mobile phone terminal 4 (2) is connected to the user PC 6 (2) through, for example, a USB cable 7 (2) to charge the data. To be able to do and migrate data.

In this case, the user PC 6 (1) can detect when the mobile phone terminal 4 (1) is connected through the USB cable 7 (1). Similarly, the user PC 6 (2) can detect when the mobile phone terminal 4 (2) is connected through the USB cable 7 (2). Therefore, when the user PC 6 (1) detects that the mobile phone terminal 4 (1) is connected through the USB cable 7 (1), the user PC 6 (1) notifies the telephone control device 1 of this. Similarly, when the user PC 6 (2) detects that the mobile phone terminal 4 (2) is connected through the USB cable 7 (2), the user PC 6 (2) notifies the telephone control device 1 of this.

However, it is conceivable that various external devices are connected to the user PCs 6 (1), 6 (2), ..., 6 (n) by USB. Therefore, the user PCs 6 (1), 6 (2), ..., 6 (n) are mobile phone terminals 4 associated with the fixed telephone terminal 2 and the like, and are mobile phones connected to the own device via USB. Register the identification information of the terminal 4. As the identification information, various information such as a mobile phone number, an IP address, and a MAC address can be used. In this example, a mobile phone number is used, for example, in consideration of enabling identification by the telephone control device 1.

Then, each of the user PCs 6 (1), 6 (2), ..., 6 (n) requests the external device to provide the identification information when the external device is connected to the own device by USB. When receiving the same identification information as the identification information registered in the own device in response to this, it is determined that the external device connected by USB is the mobile phone terminal 4, and the pairing registration including the identification information is performed. A request is formed and provided to the telephone control device 1 via a LAN. In the telephone control device 1 that has received the pairing registration request, the pairing information of the stored data for the corresponding mobile phone terminal 4 of the address management DB 104 is set to "ON", and the associated fixed telephone terminals 2, 3 In the paired state.

The operation may be performed. In this case, the fixed telephone terminals 2, 3 and the user PC 6 form a pairing registration request and a pairing deletion request in response to the operation input from the user received by the fixed telephone terminals 2, 3 and the user PC 5. Then, it may be provided to the telephone control device 1.

Further, when the user of the mobile phone terminal 4 wants to receive the incoming call to the mobile phone terminal 4 at the mobile phone terminal 4 without transferring the incoming call to the fixed telephone terminal associated with the mobile phone terminal 4 even when he / she is present. There is also. In this case, for example, a pairing refusal flag is provided in the corresponding stored data of the address management DB 104 of the telephone control device 1, and when the pairing refusal flag is "on (1)", the pairing refusal flag is set. Even if the user of the mobile phone terminal 4 is present, the corresponding pairing information may not be turned "ON". As a result, the mobile phone terminal 4 whose pairing refusal flag is "on (1)" is always "absent", and even if there is an associated fixed-line terminal, the incoming call is reflected back to it. There is no such thing.

Further, in the above-described embodiment described above, for example, a case where two mobile phone terminals are associated with the fixed telephone terminals 2 and 3 has been described as an example, but the present invention is not limited to this. One or more mobile phone terminals can be associated with the fixed telephone terminals 2 and 3.
