Among these, when the lines 51 and 52 are assigned to the portable terminals 11 and 12 of another telephone system, it is necessary to notify the telephone control device 1 of the terminal telephone number for designating the portable terminal from the network when receiving an incoming call. There is a need to use a telephone line capable of notifying additional information such as an ISDN line or an IP telephone line.

Normally, when these mobile terminals use the mobile network 4, the location registration processing is performed in advance on the management device 2 via the mobile network 4 to register that the mobile terminal 4 is accommodated in the mobile network 4. To do. On the other hand, these mobile terminals, when using the fixed network 3 via the telephone system, by performing the location registration processing to the management apparatus 2 via the fixed network 3 in advance phone system, the host terminal fixed network 3 is registered.
By performing such location registration processing, when there is an incoming call to the mobile terminal, an inquiry is made to the management device 2 from the fixed network 3 or the mobile network 4, and the obtained location registration content of the management device 2 is obtained. Based on this, the incoming call request is transferred to the network in which the portable terminal is accommodated, and the portable terminal is called.

Next, the telephone control device 1 will be described with reference to the drawings.
FIG. 2 is a block diagram of the telephone control device 1 according to the embodiment of the present invention.
As shown in FIG. 2, the telephone control device 1 includes an accommodation fixed line I / F (InterFace) 110 that is an interface connected to the fixed terminal 1-1 via the extension fixed line 7, and an extension mobile line 8. Various operations of the mobile terminal I / F 120, which is an interface connecting to the mobile terminal 1-2 and the mobile terminals 11, 12, and the fixed line I / F 130, which is an interface connecting to the fixed network 3, and various operations of the telephone control device 1 are realized. The storage unit 140 is a memory for storing programs to be executed and various data, and the control unit 150 is a functional unit for controlling each functional unit.

The storage unit 140 includes a storage table 141 that stores a priority (type) and location registration status in association with a telephone number of a portable terminal that is permitted to be stored by an administrator who manages the telephone control device 1.
The accommodation table 141 corresponds to the storage means in the present invention. As shown in FIG. 3, the telephone number and type registered in advance by the administrator of the telephone control device 1 and the location registration of the portable terminal in the management device 2 The location registration status updated in accordance with the status is associated with each other.

  For example, the type “A” is assigned to the telephone number “060-XXXXXX”, the type “B” is assigned to the phone number “060-XXXXXX-XXX”, The telephone number “060-ΔΔΔΔ-ΔΔΔΔ” is associated with the type “C”. The type “A” indicates the type for the administrator of the telephone control device 1, and the corresponding portable terminal 1-2 is a telephone set that gives top priority to establishing a communication path by outgoing and incoming calls via the fixed line 5. It is shown that. The type “B” indicates the type for the guest permitted by the administrator of the telephone control device 1, and the corresponding mobile terminal 11 sets the type “A” for establishing a call path by calling and receiving via the fixed line 5. This indicates that the telephone is the next priority after the mobile terminal. The type “C” indicates a type for a guest permitted by the administrator of the telephone control device 1, and the corresponding mobile terminal 12 is a telephone that is only allowed to establish a communication path by calling through the fixed line 5. It shows that there is.

  In addition, the location registration status of the telephone number “060-xxx-xxx” is “registered”, and that of the telephone number “060-xxx-xxx-xxx” is “waiting”. The telephone number “060-ΔΔΔΔ-ΔΔΔΔ” is “unregistered”. Among these, “registered” indicates that both the location registration of the mobile terminal with respect to the management device 2 and the extension location registration with respect to the mobile terminal in the telephone control device 1 have been completed. “Standby” indicates that the location registration of the mobile terminal with respect to the management device 2 has been completed, but the extension location registration with respect to the mobile terminal in the telephone control device 1 has not been completed and is in a standby state. Yes. “Unregistered” indicates that the location of the mobile terminal is not scheduled to be registered with the management apparatus 2 and the extension position registration with respect to the mobile terminal in the telephone control apparatus 1 is not performed.

  The control unit 150 has a function of controlling the entire telephone control device 1, and includes a storage unit 140 that is a memory that stores programs and various data for realizing various operations of the telephone control device 1, and a CPU (Central Processing Unit). And a main storage device (not shown) and the like, and by reading and executing the program of the storage unit 140, the hardware and the program cooperate to realize the above-described functions.

The control unit 150 includes an accommodation control unit 151 and a speech path establishment control unit 152.
The accommodation control unit 151 corresponds to accommodation means in the present invention, and performs a function of performing wireless communication with a mobile terminal located within the extension mobile line 8 and performs extension location registration for storing the mobile terminal in the telephone control device 1. It has a function and a function for performing a location registration process to the management apparatus 2 having the fixed line 5 relating to the portable terminal as a destination and a management process for the registration status.
The communication path establishment control unit 152 corresponds to the communication path establishment means in the present invention, and has a function of establishing a communication path between the portable terminal accommodated by the accommodation control unit 151 and the fixed network 3.

  A shared mobile terminal that can use both the fixed network 3 and the mobile network 4 with a single telephone number uses the fixed line 5 preferentially over the mobile network 4 when there is an extension mobile line 8 available. Then, a location registration request is made to the telephone control device 1. At this time, the accommodation control unit 151 transmits a control signal indicating the communication area of the telephone control device 1, for example, and performs extension position registration in response to a position registration request from the mobile terminal that has received the control signal. Thereby, wireless communication with the portable terminal becomes possible, and a communication path with the fixed network 3 can be established through the fixed line 5.

  Such a shared portable terminal is premised on the preferential use of the network side line used for location registration. For example, when the mobile terminal 11 performs location registration to the management device 2 via the mobile network 4, the mobile network 4 side, that is, the mobile line 6 is preferentially used, and a fixed network is received in response to a location registration request to the telephone control device 1. 3, the location of the extension mobile line 8 on the fixed network 3 side is preferentially used. Therefore, once the location is registered from the telephone control device 1, the mobile terminal 11 does not use the mobile line 6 and does not make or receive calls using the mobile network 4.

  On the other hand, when the telephone control device 1 accommodates the mobile terminals 11 and 12 of other telephone systems, there are situations where the mobile terminals 11 and 12 cannot use the fixed line 5 depending on the usage status of the fixed line 5 and the type of the mobile terminal. It is possible. For this reason, when all the mobile terminals located outside the service area of the telephone system 100 are automatically registered in the management device 2, the mobile network 4 can be used in the mobile terminal even though the mobile network 4 can be used for this reason. Unusable situations can occur.

In the present embodiment, the location control unit 151 of the control unit 150 manages the timing of location registration in the management device 2 and the location registration status according to the type of mobile terminal to be accommodated.
Specifically, the accommodation control unit 151 can preferentially use the fixed line 5 for the portable terminal of the type “A” having a high priority, so that the fixed network 5 can be used in response to a location registration request from the portable terminal. 3 performs location registration processing from 3 to the management apparatus 2 with the fixed line 5 as the destination. In addition, the extension position registration process to the telephone control device 1 is performed with the portable terminal, and the position registration status of the accommodation table 141 is updated to “registered”.

  On the other hand, since there is a possibility that the fixed line 5 may not be used depending on the line usage status for the mobile terminal of the type “B” having a lower priority than the type “A”, in response to the location registration request from the mobile terminal, While performing location registration processing to the management device 2 in the same manner as the type “A”, the extension location registration processing for the mobile terminal is not immediately performed, and the extension location registration is performed for the first time when the mobile terminal is made or received. And the location registration status of the accommodation table 141 is updated to “standby”. Accordingly, the portable terminal can use the fixed line 5 with priority over the portable line 6, and can particularly respond to an incoming call to the portable terminal using the fixed line 5. Further, since the mobile network 4 is kept in a usable state, the mobile network 4 can be used when the fixed line 5 cannot be used.

  In addition, for the portable terminal of the type “C” having the lowest priority, there is a high possibility that the fixed line 5 cannot be used. Therefore, the location registration processing and the extension location registration processing to the management device 2 are not performed, and the storage table 141 Update the location registration status to “unregistered”. As a result, the mobile terminal responds to an incoming call to the mobile terminal using the mobile line 6, but the fixed line 5 is given priority over the mobile line 6 as with the type “B”. It can be used. Further, since the mobile network 4 is kept in a usable state, the mobile network 4 can be used when the fixed line 5 cannot be used.

Next, the management apparatus 2 will be described with reference to the drawings.
As shown in FIG. 4, the management device 2 is composed of an information processing device such as a server device connected to the fixed network 3 and the mobile network 4 via the control line 9, and each terminal telephone number assigned to the shared mobile terminal. And a set of a storage network in which the portable terminal is currently stored and a destination telephone number in the network are associated with each other.
The fixed network 3 and the mobile network 4 transmit, to the management device 2, an incoming call destination inquiry for inquiring about the location of the mobile terminal that is the incoming call request destination via the control line 9. Then, the fixed network 3 and the mobile network 4 notify the mobile terminal of the incoming call using the accommodation network and the destination telephone number notified by the incoming call response from the management apparatus 2.

  The internal structure of the management apparatus 2 includes a communication network I / F 210 that is an interface connected to the fixed network 3 and the mobile network 4 via the control line 9, and programs and various data for realizing various operations of the management apparatus 2 described later. It comprises a storage unit 220 that stores data and a control unit 230 that controls the entire management apparatus 2.

The storage unit 220 includes a storage network capable of notifying each mobile terminal of an incoming call in the telephone system 100 and a location registration table 221 that stores a destination telephone number at that time.

As shown in FIG. 5, the location registration table 221 includes, for each calling telephone number, a receiving network that accommodates a mobile terminal corresponding to the calling telephone number and a telephone number used for calling in the receiving network. A telephone number is associated.

  For example, in the example of FIG. 5, the calling telephone number “060-XXXXX-XXX” includes the accommodation network “fixed network” and the destination telephone number “060-XXXXXX-XXXXXX”. "Is associated. This is because the call to the portable terminal corresponding to the calling telephone number “060-XXXXXX-XXX” is performed on the fixed network 3 by the destination telephone number “060-XXXXXX-XXX”. It shows that it is performed using. In addition, the calling telephone number “060-XXXXXX-XXX” is associated with the accommodation network “fixed network” and the destination telephone number “03-XXXXXX-ΔΔΔΔ”. This is because the call to the mobile terminal corresponding to the calling telephone number “060-xxx-xxxx-xxx” is made by the destination telephone number “03- ○○○○-△△△△” in the fixed network. "Indicates that this is to be done. In addition, for a state where the location is not registered and the destination telephone number is unknown, the accommodation network “-” and the destination telephone, for example, as the calling telephone number “060- □□□□-□□□□” The number “−” is associated.

The control unit 230 includes an incoming call processing control unit 231 and a location registration table control unit 232.
When receiving an incoming call inquiry about a specific mobile terminal from the fixed network 3 or the mobile network 4 via the control line 9, the incoming call processing control unit 231 refers to the location registration table 221 and sets the target call telephone number and It is a functional unit that transmits a destination response including a corresponding accommodating network and a destination telephone number. For example, as shown in the location registration table 221 of FIG. 5, upon receiving a request for the destination telephone number “060- □□□□-□□□□”, the incoming call processing control unit 231 receives the accommodation network “-”. And the destination telephone number "-". Upon receiving a request for the destination telephone number “060-XXX”, the incoming call processing control unit 231 receives the accommodation network “mobile network” and the destination telephone number “060-XXX”. “○-○○○○” is indicated.

The location registration table control unit 232 is a functional unit that controls the location registration table 221.
This location registration may be performed from each network that accommodates the mobile terminal. In the present embodiment, for example, when the mobile terminal 1-2 is accommodated in the telephone control device 1, the accommodation network is a “fixed network”. The telephone control device 1 registers the location of the destination telephone number as “060-XXXXX-XXX”. Further, when the portable terminal 1-2 is accommodated in the portable network 4, the accommodated network is “mobile network”, and its destination telephone number is “060-XXXXXX-XXXXXX”. The location is registered by the mobile network 4.

Further, when the portable terminal 11 is accommodated in the telephone control device 1, the accommodation network is “fixed network” and the destination telephone number is “03-XXXXXX-ΔΔΔΔ”. The location is registered by the telephone control device 1. Further, when the portable terminal 11 is accommodated in the portable network 4, it is confirmed that the accommodated network is “mobile network” and the destination telephone number is “060-XXXXXX-xxx”. 4 is registered.
Further, the destination telephone number is changed in response to a request from the telephone control device 1 with the calling telephone number as an initial value.

  The control unit 230 includes a storage unit 220 that is a memory that stores programs and various data for realizing various operations of the management device 2, a CPU, a main storage device, and the like, and reads and executes the programs in the storage unit 220. As a result, the hardware and the program cooperate to realize functional means described later.

If the location registration status is other than “unregistered” (step S404: NO), the presence / absence of a fixed line that can be used for the type of the terminal is confirmed (step S405). At this time, if there is no available line, whether or not the line can be used is determined in the priority order corresponding to the type of each line using terminal. When a terminal having a lower priority than the mobile terminal is in use of the line, the use of the line is stopped and a free line is prepared. Note that the usage status of the fixed line 5 is stored and managed in the storage unit 140 by the control unit 150 as call control information.
If there is no fixed line that can be used (step S405: NO), the process proceeds to step S406 to reject the incoming call.

  On the other hand, when there is a fixed line 5 that can be used (step S405: YES), extension location registration is performed by transmitting a location registration response from the accommodating mobile line I / F 120 to the terminal via the extension mobile line 8 ( Step S407). As a result, data communication with the terminal becomes possible via the extension mobile line 8, an incoming request is transmitted to the terminal (step S408), and a series of telephone control device incoming operations are terminated. As a result, the terminal displays an incoming call, and in response to a subsequent response from the terminal, the communication path establishment control unit 152 sends an incoming call response specifying a fixed line usable by the terminal from the fixed line I / F 130. The data is transmitted to the fixed network 3 and a call path between the fixed network 3 and the terminal is established using the fixed line. As a result, the terminal shifts to a call state.

As described above, since only the portable terminal set in advance in the accommodation portable table 141 by the administrator uses the fixed line network 5 associated with the telephone control device 1, the administrator uses the telephone control device 1 comfortably. it can.
In the present embodiment, the types “A”, “B”, and “C” are managed in association with telephone numbers, but the present invention is not limited to this.
