In addition, in the components of the telephone transfer device 20 according to the present embodiment, those having the same configuration and function as those of the telephone transfer device 10 described in the first embodiment are denoted by the same reference numerals. Detailed description thereof will be omitted.

Here, the outline | summary of the telephone transfer system in this Embodiment is demonstrated with reference to FIG.
The femto BTS 2 is a very small radio base station whose communication range 2-1 is about several tens of meters, and is connected to the mobile communication service network 1-2 via the broadband line 1-1. A femto BTS installed in a specific area, such as a weak radio wave area or in a home, performs wireless communication with a terminal device that cannot wirelessly communicate with a normal mobile communication radio base station 4 or a terminal device that exists in the home. The mobile communication by these terminal devices is realized.
For example, as shown in FIG. 4, a femto BTS 2 installed at home has its communication range 2-
1, that is, by performing wireless communication with the terminal device 3-a of the user A located at home and the terminal device 3-b of the user B, the terminal devices 3-a, 3 -B
Realizes mobile communication.

The telephone transfer device 20 is connected to the femto BTS 2 via the network 1 such as the broadband network 1-1, and is a terminal device (in the communication range 2-1 of the femto BTS 2) (
In FIG. 4, the incoming calls of the terminal devices 3-a and 3-b) are monitored to determine whether or not to transfer the incoming calls. When an incoming call is transferred, a transfer destination terminal device is selected from the terminal devices existing in the communication range 2-1 of the femto BTS 2 and transfer control for connecting the incoming call to this terminal device is performed. Run.
Specifically, as shown in FIG. 4, when the user X sends a call signal to the user B, the call signal is transmitted via the normal mobile communication radio base station 4 to the mobile communication service network 1-2. The terminal device 3-b of the user B is called through At this time, since the terminal device 3-b exists in the communication range 2-1 of the femto BTS 2, the telephone transfer device 20 monitors the incoming call from the user X to the terminal device 3-b and performs this incoming call. If it is determined that the call needs to be transferred, another terminal device existing in the communication range 2-1 of the femto BTS 2, that is, the terminal device 3-a of the user A is selected as the transfer destination, and the incoming call is selected as the terminal device. Connect to 3-a.

Next, the configuration and function of the telephone transfer device 20 according to the present embodiment will be described in detail.
As shown in FIG. 3, the telephone transfer device 20 according to the present embodiment includes a communication execution unit 110 that performs packet communication with the femto BTS 2 via a broadband network, and terminal devices 3-a to 3-.
The area information acquisition unit 220 that acquires area information indicating whether or not 3-n is in a state where wireless communication with the femto BTS 2 is possible, and the area information includes information specifying the terminal devices 3-a to 3-n. From the member information storage unit 230 that stores the member information 231 associated with the information, and the transfer control unit 240 that performs transfer control on the incoming call of the terminal device 3-n existing in the communication range of the femto BTS 2 It is configured.

The location information acquisition unit 220 exists in the communication range of the femto BTS 2 and the femto BTS 2
The terminal device 3-n in a state where wireless communication with the femto BTS 2 can be performed, and the terminal device 3-n not in the communication range of the femto BTS 2 or in a state where wireless communication with the femto BTS 2 cannot be performed In-zone information is acquired with n as an “out-of-service terminal”.

Specifically, as illustrated in FIG. 4, the terminal devices existing in the communication range 2-1 of the femto BTS 2 are the user A terminal device 3-a and the user B terminal device 3-b. Here, if both of these terminal devices 3-a and 3-b are in a state in which wireless communication with the femto BTS 2 is possible (power is turned on and in a standby state), the presence of the terminal devices 3-a and 3-b is present. The area information is both “area terminal”.

On the other hand, the terminal device 3- of the user C existing outside the communication range 2-1 of the femto BTS 2
That is, since c is a terminal device that cannot perform wireless communication with the femto BTS 2, the location information of the terminal device 3-c is “out-of-service terminal”. Further, even if the terminal device existing in the communication range 2-1 of the femto BTS 2 cannot perform wireless communication with the femto BTS 2 because the power is turned off, the in-zone information is similarly “out-of-service terminal”. Become.

The member information storage unit 230 updates the member information 231 with the latest location information acquired by the location information acquisition 220. That is, when new location information is acquired by the location information acquisition unit 220, the member information storage unit 230 receives the new location information as an input, and the member information 2
31 is updated and the latest member information is stored.
Here, the member information 231 stored in the member information storage unit 230 is the femto BTS2
A telephone number for identifying the terminal devices 3-a to 3-n capable of wireless communication, ID information corresponding to the telephone number (corresponding to the name of the terminal device), and the location information acquisition unit 220 acquires It can be information associated with the zone information.

For example, FIG. 5 shows an example of member information 231. As shown in FIG. 5, member information 231
Is data in which “ID”, “phone number”, and “location information” are associated with each terminal device. The member information 231 in the configuration shown in FIG. 4 will be described as an example. The telephone number of the terminal device 3-a with the ID “user A” is “090-1111-***”, and “user A” is “
The member information 231 indicates that the terminal is in the “service area terminal” state.
As a result, the member information 231 stored in the member information storage unit 230 is stored in the femto BT.
It can be the latest information indicating whether or not the terminal device exists in the communication range of S2 and can wirelessly communicate with the femto BTS.

The transfer control unit 240 stores transfer setting information in which the connection order of incoming calls by transfer is set for each information (for example, ID information) in the member information 231 corresponding to the telephone number of the caller. The terminal device 3-n that is a transfer destination of the incoming call is selected based on the member information 231 and the transfer table 241, and the incoming call is connected to the selected terminal device 3-n. The transfer control to be executed is executed.
An example of the transfer table 241 is shown in FIG. As shown in FIG.
1 shows transfer setting information in which the priority order of the terminal device 3-n serving as the transfer destination is set for each caller source number of the incoming call in accordance with each “ID” stored in the member information 231 shown in FIG. It is the stored information.
When the femto BTS 2 of the telephone transfer system according to the present embodiment is installed at home, all the users registered in the member information 231 may be automatically registered as transfer destinations of transfer setting information.

For example, when an incoming call to the user A whose source number is “090-4444-****” needs to be transferred, the transfer control unit 240 sets the user B as a candidate for the terminal device to be transferred. Is preferentially selected. If the location information of the user B in the member information 231 is “a visited terminal”, the transfer control unit 240 determines the user B as the transfer destination. Here, member information 23
1, if the location information of the user B is “absent terminal”, the transfer control unit 240
The user C having the next priority order is selected from the transfer table 241 as a transfer destination candidate, and if the user C's location information in the member information 231 is confirmed and is a “location terminal”, the user C is set as the transfer destination. decide.

Further, in the transfer setting table 241 shown in FIG. 6, the transmission source number is “090-4444- *.
The transfer setting information corresponding to the incoming calls “***” and “090-5555-***” is stored for both users A and B, but the source number is “090-666-***”. Transfer setting information corresponding to the incoming call is stored only in user A. That is, "090-44
44-*** ”and“ 090-5555-*** ”are the caller source numbers of user A,
B is a transmission source number that permits transfer of an incoming call (hereinafter referred to as “transfer permission number”). The transmission source number of “090-6666-***” is a transfer permission number for user A. However, in User B, the caller number is not permitted to transfer an incoming call (hereinafter referred to as “transfer prohibited number”).
Thereby, the transfer control unit 240 can select the transfer destination according to the caller of the incoming call.
For an incoming call from a caller number that is not stored in the transfer setting table 241, a predetermined terminal device 3-n may be selected as the highest priority transfer destination.

Next, the operation of the telephone transfer apparatus 20 according to the present embodiment will be described with reference to the flowchart shown in FIG. 7 and the block units shown in FIGS.
As illustrated in FIG. 7, the telephone transfer device 20 according to the present embodiment includes the location status (location information) of the terminal devices 3-a to 3-n existing in the communication range 2-1 of the femto BTS 2. If there is no change (S201: “No”), a standby state for detecting a change in the location information is continued (S201).

If there is a change in the location information (“Yes” in S201), the location information acquisition unit 220 acquires the latest location information from the femto BTS 2 and stores the member information stored in the member information storage unit 230. Is updated with the latest location information obtained (S202).
After updating the member information 231, the transfer control unit 240 determines whether there is an incoming call for the terminal device 3-n whose in-zone information stored in the member information 231 is “in-zone terminal” (S
203) If there is no incoming call to the terminal in the area (“No” in S203), the femto BTS2
(S201).

When there is an incoming call in the serving terminal (“Yes” in S203), the transfer control unit 240 determines whether or not transfer control is required for the incoming call of the serving terminal (S204). When the transfer control unit 240 determines that transfer control is not necessary (“No” in S204), the telephone transfer device 20 ends the operation without executing transfer control for the incoming call.
Here, regarding the determination of whether or not the transfer control unit 240 requires transfer control for an incoming call, for example,
Whether or not transfer control is necessary can be determined by detecting an incoming call that does not receive an incoming call response even after a predetermined time has elapsed. Further, the transfer control unit 240 may determine whether or not the transfer control of the incoming call is necessary by receiving the transfer request signal of the incoming call with no incoming response transmitted from the femto BTS 2.
Note that the transfer control unit 240 may determine whether or not transfer control is necessary for an incoming call depending on the presence or absence of a ringback tone. Specifically, when there is a ringback tone (during a normal call), check if there is an incoming call response after a certain period of time, and when there is no ringback tone (during a call or out of service area, etc.) May determine that there is immediate transfer control.

On the other hand, when it is determined that transfer control is necessary (“Yes” in S204), the transfer control unit 240 uses the caller source number (transfer permission number) for which transfer is permitted for the caller number of the incoming call that executes the transfer control. Whether or not there is is determined based on the transfer setting table 241 (S205).
If the transfer setting information corresponding to the caller number is not stored in the transfer table 241, that is, if the caller source number of the incoming call is a transfer non-permission number (“No” in S205), the telephone transfer device 20 The operation is terminated without executing transfer control for the incoming call.
When transfer setting information corresponding to the caller number is stored in the transfer table 241, that is, when the caller source number of the incoming call is a transfer permission number (“Yes” in S205), the transfer control unit 240 receives the incoming call The presence / absence of a call transfer destination is determined (S206).

Here, the operation of determining whether or not there is a transfer destination by the transfer control unit 240 will be described. Based on the transfer setting table 241, the transfer control unit 240 sequentially selects terminal devices 3-n having a higher priority as transfer destination candidates, and member information 231 corresponding to the selected transfer destination candidate terminal device 3-n. It is executed by checking the status of the location information in the area.
That is, the transfer control unit 240 determines that “there is a transfer destination” if the location information in the member information 231 of the terminal device 3-n that is the transfer destination candidate selected based on the transfer table 241 is “a visited terminal”. If it is “out-of-service terminal”, it is determined that “no forwarding destination”.

When it is determined by the transfer control unit 240 that “no transfer destination” (“No” in S206),
The telephone transfer device 20 ends the operation without executing the transfer control for the incoming call.
When the transfer control unit 240 determines that “there is a transfer destination” (“Yes” in S206)
The transfer control unit 240 executes transfer control for connecting the incoming call to the terminal device 3-n that is the selected transfer destination. Here, the transfer control by the transfer control unit 240 may be executed by transmitting a control signal from the transfer control unit 240 to the femto BTS 2, or the transfer control unit 2.
It may be executed by transmitting a control signal from 40 to a call control system (not shown) of the mobile communication service network 1-2.

When transfer control is executed by the transfer control unit 240, the telephone transfer device 20 determines whether or not the transfer destination has responded to the incoming call by transfer after a predetermined time has elapsed (S208).
When it is determined that the transfer destination is not responding to the incoming call (“No” in S208), the telephone transfer device 20 causes the transfer control unit 240 to confirm the presence / absence of the transfer destination again (S206).
If it is determined that the transfer destination is responding to the incoming call (“Yes” in S208), the telephone transfer device 20 ends the transfer operation because the transfer control of the incoming call has been completed normally.

Next, the execution sequence of the telephone transfer service of the telephone transfer system in the present embodiment will be described with reference to the sequence diagram shown in FIG.
As shown in FIG. 3, the telephone transfer system according to the present embodiment includes a radio base station (femto BTS) 2, a telephone transfer device 20, and terminal devices 3-a to 3-n. As shown in FIG. 4, when the incoming call of the terminal device 3-b existing in the communication range 2-1 of the femto BTS 2 is transferred by the telephone transfer device 20, the telephone transfer service by the telephone transfer system in the present embodiment The execution sequence will be described.

As shown in FIG. 8, the latest location information is transmitted from the femto BTS 2 to the telephone transfer device 20 (S301). When the telephone transfer apparatus 20 acquires the area information transmitted from the femto BTS 2, the telephone transfer apparatus 20 updates the member information 231 with the latest area information acquired (S302).
As shown in FIG. 4, when the user X makes a call to the user B, the femto BTS 2 transmits a call signal (incoming call notification) to the terminal device 3-b of the user B (S303).

The telephone transfer device 20 is connected to the terminal device 3- existing in the communication range 2-1 of the femto BTS 2.
The incoming call of b is monitored (S304), and if there is no incoming response by the user B to the incoming notification from the femto BTS 2 after a predetermined time has passed, transfer control is required for the incoming call of the user B Judge. Specifically, the telephone transfer device 20 receives the transfer request transmitted from the femto BTS 2 (S305), and determines that transfer control for the incoming call of the terminal device 3-b is necessary. In addition, regarding the determination of the necessity of transfer control for an incoming call, if it is a method that can identify that no incoming call response has been made even after a certain period of time,
The transfer request from the femto BTS need not be received.

For example, as shown in FIG. 4, when the user B is located on the first floor of the home but the terminal device 3-b of the user B is located on the second floor, the incoming call to the terminal device 3-2 is made. If the user B does not respond even after a certain period of time, the femto BTS 2 transmits a transfer request to the telephone transfer device 20. When receiving the transfer request transmitted from the femto BTS 2, the telephone transfer device 20 determines that transfer control for the incoming call of the user B is necessary.

The telephone transfer device 20 sets the transfer destination candidate of the incoming call of the terminal device 3-b as the transfer setting table 241.
Is selected based on the transfer setting information (S307).
For example, if the telephone number (source number) of the user X is “090-5555-***”, according to the transfer setting table shown in FIG. The user C is the user C, and the telephone transfer apparatus 20 selects the user C as a transfer destination candidate.

When the user C is selected as a transfer destination candidate, the telephone transfer device 20 confirms the location information of the terminal device 3-b of the user C in the member information 231 and determines whether transfer is possible (S30).
7).
For example, according to the member information 231 shown in FIG. 5, the location information of the user C is “out-of-service terminal”, indicating that wireless communication with the femto BTS 2 is impossible. Therefore, the telephone transfer device 20 determines that transfer of the incoming call to the user C is impossible.

If it is determined that the incoming call transfer to the user C is impossible, the telephone transfer device 20 selects the transfer destination of the incoming call again (S309). Specifically, according to the transfer setting table shown in FIG. 6, the next priority transfer destination candidate corresponding to the caller source number “090-5555-***” is the user A. The transfer device 20 selects the user A as a transfer candidate.

When the telephone transfer apparatus 20 confirms that the area information of the terminal apparatus 3-a of the user A is the area terminal based on the member information 231, the telephone transfer apparatus 20 determines the user A as a transfer destination for the incoming call of the user B ( (S310), transfer control for connecting the incoming call of user B to user A is executed (step S310).
S311, S312).
Here, the transfer control executed by the telephone transfer device 20 transmits the transfer destination information (transfer control information) to the femto BTS 2 (S311), and receives the transfer control information from the femto BT.
This may be realized by connecting the incoming call to the transfer destination in S2 (S312).

When transfer control for connecting the incoming call of user B to user A is executed, femto BTS 2
Transmits a call signal (transfer incoming notification) by transfer to the terminal device 3-a of user A (
S313).
The terminal device 3-a of the user A who is the serving terminal transmits an incoming call response to the forward incoming call notification to the femto BTS 2 (S314), and starts a call with the user X.

When the incoming call response from the user A is received, the femto BTS 2 notifies the telephone transfer device 20 that the transferred incoming call has been “call response” (S315). As a result, the telephone transfer apparatus 20 that has recognized that the telephone transfer service has been executed normally ends the telephone transfer operation.

Thus, according to the telephone transfer system including the telephone transfer device according to the present embodiment, the latest state of the terminal device existing in the radio communication area of the radio base station is managed as member information. By executing a telephone transfer service for the terminal device in the wireless communication area of the wireless base station based on the latest member information, it is possible to communicate in the area where the terminal device corresponding to the transfer source telephone number is located It is possible to select another terminal device as the transfer destination.
