The wired telephone call system 100 using the wireless communication module according to the present invention has a wired telephone connection unit 30, and a plurality of wired telephones 1a, 1b, 1c, ... 1n in the wired telephone connection unit 30. Is connected via a telephone line. Each of the landline telephones 1a, 1b, 1c, ..., 1n has a unique telephone number.

The system 100 further includes a plurality of wired telephones 1a, 1b, 1c, 1n connected to the plurality of wireless communication modules 10a, 10b, 10n and the wired telephone connection portion. It has an exchange unit 23 for exchanging the connection, and further has a guide unit 24 for transmitting the information necessary for a telephone call to the wireless communication module or wired telephone connected to the switch unit 23 is connected. The exchange unit 23 may exchange in the same manner as the exchange connection in a known private branch exchange (PBX) or key system (Key system). The guide unit 25 is a wireless communication module (10a, 10b, ..., 10n) or wired telephone (1a) connected to the exchange unit 23 for information necessary for a telephone call, such as a ring signal, a ring tone signal or a busy signal , 1b, ..., 1n). In addition, according to the present invention, as will be described later, delivers the message required for the call.

The system 100 according to the present invention has a decoder unit 24 which decodes and converts a telephone signal having a DTMF form input from a wireless communication module or a wired telephone connected to the exchange unit 23 to data it.

The plurality of wireless communication modules 10a, 10b, ..., 10n, the plurality of wireline telephones 1a, 1b, ..., 1n connected through the wired telephone connection unit, and the exchange unit 23. ), The guide unit 25 and the decoder unit 24 are connected to the control unit 21 and are controlled by the control unit 21. The control unit 21 is composed of a central processing unit (CPU) and a memory unit, and the memory unit stores a control program for determining the operation order of the central processing unit or data to be stored in the central processing unit.

The telephone signal decoded and decoded by the decoder unit 24 is input to the controller 21, and the controller 21 utilizes the inputted telephone signal data to connect an external telephone to a landline telephone (or a wired telephone). Set the currency path between them.

At this time, the switching unit 23 is a wireless communication module switching unit 232 for switching a wireless communication module for receiving or transmitting a telephone signal, and a wired telephone connected to the landline telephone connection unit for receiving or transmitting a telephone signal It may have a wired telephone switching unit 231 to. In addition, the decoder unit 24 is connected to the wireless communication module decoder unit 242 and the wired telephone exchange unit 231 for decoding a telephone signal input from a wireless communication module connected to the wireless communication module exchange unit 232. It may have a genetic telephone decoder 241 for decoding the telephone signal input from the landline telephone.

2 illustrates a case where a plurality of wireline telephone systems 100 using a wireless communication module having the configuration of FIG. 1 are installed. With respect to the wireless communication telephone network 300, the systems 100 may be installed for each region, or when the system 100 is completed in a mobile manner, a plurality of systems may be installed even in the same region, depending on a moving place.

In a landline telephone call system using a wireless communication module according to the present invention having such a configuration, a call is typically realized between an external telephone 210 or 410 and the landline telephones 1a, 1b, ..., 1n. The process is as follows.

First, a process of making a call from the external telephone 210 or 410 to the wired telephones 1a, 1b, ..., 1n will be described.

The external telephone 210 or 410 transmits a telephone signal to any one of the wireless communication modules 10a, 10b, ..., 10n. The signal is received by the target wireless telephone communication module through the wireless telephone communication network 200, and the call mode is maintained between the external telephone 210 or 410 attempting to make the call and the target wireless communication module. In other words, when a user of an external telephone enters a telephone number of a wireless communication module into a working telephone, the telephone transmits a telephone signal and the transmitted telephone signal is received by a desired wireless communication module via the wireless telephone communication network 200. The call mode is maintained between the external telephone and the wireless communication module.

In this case, the switching center 350 of the wireless telecommunication network 200 assigns a representative telephone number to any one of the wireless communication modules 10a, 10b, ..., 10n, and forwards the telephone numbers of the remaining wireless communication modules. Can be assigned by number. Then, when the external telephone user makes a call to the representative telephone number, if the wireless communication module to which the representative telephone is assigned is in use, the switching center 350 of the wireless communication network automatically sends an outgoing telephone signal to another wireless communication module. Forward it. Therefore, the external telephone user does not need to know all the telephone numbers of each wireless communication module, but needs to call only the representative telephone.

The control unit 21 is connected to the wireless communication module (10a, 10b, ..., 10n) and always check their telephone signal reception status. When the wireless communication module receives a telephone signal from the external telephone (210, 410), the control unit 21 detects this. Then, the control unit 21 causes the switching unit 23 to connect the wireless communication module receiving the telephone signal thereto and to operate the decoder unit 24 connected to the switching unit 23.

Next, the control unit 21 causes the guide unit 25 to transmit a message for guiding the input of the unique number of the intended wireline telephone to the wireless communication module that detects the telephone reception. Since the wireless communication module has already established a call mode with an external telephone, the guide message of the guide unit 25 is transmitted to an external telephone.

Accordingly, when the user of the external telephone 210 or 410 inputs the unique number of the target wired telephone, the input signal is transmitted to the decoder 24 through the switching unit 23 via the wireless communication module in which the call mode is set. . An input signal, which is a telephone number of a telephone object of a telephone call input by an external telephone, is transmitted to the decoder unit 24 in the form of a DTMF signal through a wireless communication module, and the decoder unit 24 decodes the signal into data. The unique telephone number data of the decoded destination wireline telephone is input to the control unit 21.

The control unit 21 that reads the destination wireline phone unique number data checks whether the destination wireline phone is busy. If a call is in progress, the controller 21 causes the guide unit 25 to transmit a busy message to the wireless communication module to inform the external telephone user that the destination wired talker is busy.

If the destination wired telephone is not in a call, the controller 21 causes the switch 23 to connect the destination wired telephone. Then, the guide unit 25 delivers the ring to the destination wireline telephone connected to the exchange unit (23). When the user of the target wired telephone receives a call, the call can be made between the external telephone and the target telephone period.

A case where a telephone is made to an external telephone 210 or 410 by using any one of a plurality of landline telephones 1a, 1b, ..., 1n connected to the system 100 will be described.

First, for example, the wired telephone attempts to make a call by turning off the hook. The control unit 21 is connected to a plurality of wired telephones 1a, 1b, ..., 1n connected thereto via the wired telephone connection unit 30 to check the telephone signal state of the wired telephone.

If there is a hook-off, the control unit 21 detects a call attempt of the wireline telephone. Then, the control unit 21 controls the exchange unit 23 so that the wired telephone that attempts to make a call is connected to the exchange unit 23. Also, the decoder unit 24 connected to the exchange unit 23 is operated.

Next, the controller 21 finds whether there is a resting wireless communication module.

If the resting wireless communication module is not found, the control unit 21 causes the guide unit 25 to notify the wired telephone that is attempting to call a busy message (for example, a ring tone). And the control unit 21 cuts off the connection of the exchange unit 23 of the wired telephone attempting the call.

If a resting wireless communication module is found, a call tone is transmitted to the landline telephone, and the landline telephone user inputs a telephone number of an external telephone to be called. The external telephone signal, which is a DTMF signal, is transmitted to the decoder unit 24 through the exchange unit 23, decoded and dataized therein, and input to the control unit 21. In this case, the control unit 21 determines whether the external telephone number input is completed. For example, when there is no input for 8 seconds, it may be determined that the input of the target external telephone number has ended. Alternatively, if the user of the landline phone enters special characters, for example, * and # characters, the input may be determined to have been terminated.

Next, the control unit 21 connects the found break wireless communication module to the exchange unit 23. And the phone number data of the external telephone for the call is transferred to the wireless communication module connected to the exchange unit (23). In this case, for example, the control unit 21 and the wireless communication module may be connected by RS 232C communication to transmit data. The wireless communication module transmits the destination external telephone number to the base station 310 of the wireless telephone communication network 200 using the destination telephone number.

In this way, the present invention exchanges and connects a plurality of wireless communication modules and a plurality of wired telephone periods connected to an external wireless telephone communication network through an exchange unit to establish a communication path between the wireless communication module and the wired telephone. The telephone is connected to an external telephone connected to an external wireless telephone communication network and the landline.

The charge for the normal use of the radiotelephone is that the radiotelephone transmits a telephone signal with its own phone number data to the base station of the radiotelephone network, and receives the radiotelephone network which confirms the radiotelephone connected to the radiotelephone network. The exchange shall charge by measuring the usage time of the radiotelephone network of the radiotelephone.

Since the wired telephone call system 100 using the wireless communication module according to the present invention makes a call between an external telephone and the wired telephone through a wireless telephone communication network, the use of the wired telephone becomes a use of the wireless telephone communication network. Therefore, it is possible to charge the wired telephone user based on the time of use of the wireless telephone communication network used by the wireless communication module in which the communication path is established in exchange with the wired telephone.

In this case, the wireless communication module can measure the usage time in the same manner as in the conventional wireless telephone, and accordingly, charging can be made for the wired telephone. However, in order to charge each wired telephone, it is necessary to check which wired telephone is connected to the wireless telephone communication network 300 to which wireless telephone module is connected to which wireless communication module. In such a case, the wired telephone connected to the specific wireless communication module can be charged based on the network usage time of the wireless communication module.

According to the present invention, the wireless communication module connected to the base station 310 of the external wireless telephone communication network 300 transmits the wired telephone number data exchanged with itself to the base station. Accordingly, the switching center of the radiotelephone communication network 300 can identify which wired telephone used the radiotelephone communication network 300 using which radio communication module, and therefore, it is possible to charge the specific wired telephone.

When the wired telephone that attempts to make a call to an external telephone 210 or 410 is exchanged and connected to any one of the plurality of wireless communication modules 10a, 10b, ..., 10n, the control unit 21 is configured to make a call. Wireline telephone number data together with the external telephone number is transmitted to the wireless communication module. Then, the switched wireless communication module inputs the wireline telephone number data to the exchange field 350 and the protocol field promised with the wireless communication network 300 and transmits the data to the base station. Accordingly, the switching station of the wireless communication network specifies the wired telephone using the wireless communication module, measures the use time of the wireless communication module exchanged with the wired telephone, and charges the wired telephone.

Referring to FIG. 3, when a specific wireline telephone attempts to make a call with an external telephone, a process of establishing a call path between the wireline telephone and the base station of the external wireless telephone communication network 300 will be described.

First, any of the landline telephones attempt to make a call. (S301) Then, the controller 21 detects this and stores the wired telephone. For example, the controller 21 configures a record for each landline telephone number so as to record call detection in another field using the telephone number of each landline telephone as a key field. If a call is detected, the call detection is recorded in the field.

Next, the control unit 21 controls the exchange unit 23 so that the wired telephone that attempts to make a call is connected to the exchange unit 23. (S303) Also, the decoder 24 connected to the exchange 23 is operated. (S304)

Next, the controller 21 finds whether there is a resting wireless communication module (S305).

If the resting wireless communication module is not found, the control unit 21 causes the guide unit 25 to notify the wired telephone that is attempting to call a busy message (for example, a ring tone). (S306) And the control unit 21 blocks the connection of the exchange unit 23 of the wired telephone attempting the call. (S307)

If a resting wireless communication module is found, a call tone is transmitted to the landline telephone, and the landline telephone user inputs a telephone number of an external telephone to be called. (S308) The destination external telephone telephone number signal, which is a DTMF signal, is transmitted to the decoder unit 24 through the exchange unit 23, decoded and dataized therein (S309), and input to the control unit 21 (S310). In this case, the control unit 21 determines whether the external telephone number input is completed. (S311)

When the input of the destination wireline telephone number is completed, the controller 21 connects the found break wireless communication module to the switch 23. (S312)

And the phone number data of the external telephone for the call and the phone number data of the wired telephone to attempt the call is transmitted to the wireless communication module connected to the exchange unit (23). For example, the control unit 21 and the wireless communication module are connected by RS 232C communication, and the control unit 21 can transmit data to the wireless communication module.

Referring to FIG. 2, a plurality of systems 100 of the present invention that enable a call with an external telephone 210 or 410 using a wireless telephone communication network 300 may be installed. In this case, there may be a telephone number of the same landline telephone for another system. In the same system, each landline telephone has a different number, but in another system, a landline telephone having the same telephone number may exist. Thus, exchanges in wireless telecommunication networks must be able to distinguish substantially the same landline telephone number for billing purposes.

5 shows the format of data transmitted from the control unit 21 to the wireless communication module.

In the case of (a) of FIG. 5, the controller 21 transmits header information, data having a target wireline telephone number, and data having a telephone number of a wireline telephone to a wireless communication module connected thereto. At this time, the switching center 350 of the wireless telephone communication network 300 should store the telephone number of the wireless communication module usable for each wired telephone. For example, it has a wireless communication module telephone number available for each genetic telephone telephone number as a database. The switching center 350 may then distinguish them as a wireless communication module telephone number for the same wired telephone telephone number.

As shown in (b) of FIG. 5, the controller 21 may transmit data having a system identification number in addition to the header information, the target wireline telephone number, and the wireline telephone number to the wireless communication module connected to the exchange. In this case, the switching center 350 of the wireless switched telecommunication network should store the system number to which each landline telephone belongs. Thus, the switching center can distinguish the same landline telephone telephone number as the system number. At this time, the control unit 21 stores the identification number of the system for the wireline telephones.

The wireless communication module receiving data including the wired telephone number from the controller 21 transmits a telephone signal to the base station of the wireless telephone communication network 300. In this case, the wired telephone telephone number or the wired telephone telephone number and the system number are inputted in the protocol field already defined with the switching center of the wireless telephone communication network 300. For example, when the wireless telecommunication network 300 is CDMA, for the protocol shown in FIG. 6, the record type of the Origination Continuation Message is set to the Keypad Facility (0000 0011), and the telephone number is set to the telephone line in the Type-Specific fields. Alternatively, you can make a call to a base station by entering your landline phone number and system number. In this case, an ASCII code, which is not used to confirm the number of the landline telephone, may be input in the field.

In this way, the exchange station of the wireless telecommunication network 300 can identify which wired telephone has used the wireless telecommunication network 300 using which wireless communication module, and therefore, it is possible to charge the specific wired telephone. .

4 is a flowchart illustrating a processing operation of the controller 21 according to the present invention.

First, when a specific wired telephone attempts to make a call, the controller 21 detects this and stores the wired telephone even when making a call. (Step S401)

Next, the conventional wireless communication module connection procedure as described above is performed. (Step S402) That is, when the call is connected to the wired telephone to the switching unit 23, the decoder unit 24 is operated, and if a break wireless communication module is found, the call tone is notified to the wired telephone side, and the target wired telephone number is input. When the decoder is decoded by the decoder 24 and inputted, the input end is checked and the found break wireless communication module is connected to the switch 23.

Next, the controller 21 transmits the data as shown in FIG. 5 to the wirelessly connected wireless communication module. (Step S504)

Thereafter, the wireless communication module causes the base station of the wireless telephone communication network 300 to be transmitted. At this time, the landline telephone number or the landline telephone number and the system number are transmitted to the base station. (Step S505)

As described above, the present invention transmits the telephone number data of the wired telephone to the wireless communication module exchanged with the wired telephone, and the wireless communication module transmits the telephone number data to the wireless telephone communication network. Accordingly, the switching station of the wireless communication network can specify a wired telephone using the wireless communication module, and can charge the wired telephone by measuring the use time of the wireless communication module exchanged with the wired telephone.

It will be appreciated that this has been achieved the object of the present invention.
