Description

Wireless LAN system and wireless LAN system control method and control program {WIRELESS LAN SYSTEM AND CONTROL METHOD AND CONTROL PROGRAM OF WIRELESS LAN SYSTEM}

In recent years, mobile telephones have developed remarkably, and the number of subscribers to mobile telephone lines (hereinafter referred to as wireless telephone lines) of mobile communication lines has exceeded the number of subscribers of fixed telephone lines due to the reduction in call charges and the release of new models. . For this reason, it is common to use a division in which a user possesses both a mobile telephone using a wireless telephone line and a fixed telephone using a fixed telephone line to communicate with a fixed telephone indoors and to communicate with a mobile telephone while going out.

Reflecting such a situation, the number of subscribers of fixed telephone lines is currently decreasing, but further improvements are being made in the future regarding the usage rates (basic charges and call charges), communication speed, and reliability of mobile telephone lines. Assuming the equivalent of a fixed telephone, in the near future the use of fixed telephone lines by users will inevitably decrease significantly.

On the other hand, it is expected that communication functions will be added to a large number of electronic devices (such as television receivers, video decks, various cameras, etc.) in the near future, and that various data can be transmitted and received to and from server devices. In this case, it is conceivable that transmission and reception means for performing communication using a wireless telephone line is added to each electronic device.

Here, assuming that a case where a transmission / reception means using a wireless telephone line is added to various electronic devices, if a different wireless telephone line is set for each electronic device, that is, a separate telephone number is given for each one, And a number of electronic devices, because a number of problems arise, such as a problem of a telephone number managed by a host station, an increase in the basic charge of a wireless telephone line borne by a user, and exhaustion of telephone number resources. You should build a system that can be used in common.

In order to construct such a system, it is conceivable to establish a network connection using a LAN. For example, a short-range wireless communication device such as Bluetooth (see January 17, 2000, page 37-44) of each electronic device may be attached to a wireless device. In addition to establishing a LAN, an originated call from a telephone device outside the LAN is received by a master communication device such as a cellular phone in which a unique wireless telephone line is set in the wireless LAN to establish communication. In the communication establishment state by the wireless communication system, another electronic device (slave communication device) in the wireless LAN further communicates with the source telephone apparatus through the master communication device by further communicating with the near field wireless device with respect to the master communication device. It is becoming.

However, in this method, only the mobile phone serving as the master communication device is used directly by the wireless telephone line, and each other electronic device which is a slave communication device does not use the wireless phone line, so that the mobile phone can be used as a repeater. It is simply indirectly connected to the line.

Therefore, since the master communication device must always be in a communication connection state during communication between the telephone device outside the LAN and the slave communication device, unnecessary power consumption occurs. In addition, for example, when the telephone apparatus outside the LAN is a computer such as a server apparatus, and when receiving large-capacity data such as video information transmitted from the computer to an electronic device (slave communication apparatus) in the wireless LAN, the portable telephone ( The amount of power consumed by the master communication device) becomes excessive, and as a result, the processing of the microprocessor of the current mobile phone is excessive.

On the other hand, it is conceivable to mount a large-capacity battery or a microprocessor capable of processing large-capacity data with respect to the mobile phone. However, such a configuration impairs the portability of the mobile phone and increases the cost considerably. Not realistic

Furthermore, in this method, since the mobile phone is used as the master communication device, there is a problem that the mobile phone cannot be moved and used in order to perform communication between the telephone device outside the LAN and the electronic device (slave communication device). In addition to the cellular phone, a wireless telephone line is required to have a mobile communication function for each electronic device in the WLAN.

On the other hand, in the current radiotelephone system, since the radiotelephone line is managed by a host station having a plurality of base stations and one central control station, the position registration with respect to the base station must be performed in order to use the radiotelephone line. Here, if a plurality of communication devices in the wireless LAN each perform location registration using the same telephone number, the current host station cannot cope. Therefore, in order to construct a wireless LAN system using a wireless telephone line, a configuration in consideration of the location registration problem of each communication device should be taken.

Moreover, as a measure for solving such a problem, the present applicant first proposed "control system for delegation of telephone lines" (Japanese Patent Application No. 2000-122791, Japanese Patent No. 3132213). When this system is applied to a wireless LAN using a wireless telephone line, each slave communication device is a slave ID (for example, a phone number generated based on the master ID (for example, telephone number "090-1234-5678") of the master communication device. (090-1234-5678-01), "090-1234-5678-02", ...) separately register the location to the base station to perform communication through the host station, and therefore from the master communication device After receiving control delegation, it becomes possible to establish a wireless telephone line without using a master communication device as a repeater.

However, in this system proposed earlier, when each slave communication device that has been delegated control performs wireless telephony communication to a telephone device outside the LAN by using the slave ID, the host station must authenticate the correspondence between the slave ID and the master ID. Therefore, there was a weak point that the host station (communication service provider) puts a burden on the processing.

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

First, the basic principle and the like of the present invention will be described with reference to FIGS.

Industrial Applicability The present invention is applied to a wireless LAN system in which a plurality of electronic devices are connected to a network and short-range wireless communication is performed between each electronic device by a radio signal. As a hardware configuration for this, as shown in FIG. 1, each electronic device uses a short range wireless communication unit 4, which is a short range wireless communication means for transmitting and receiving wireless signals between each electronic device in a network, and a wireless telephone line. A transmitter / receiver 5, which is a transmission / reception means for transmitting and receiving a wireless signal, and a control unit 6, which is a control means for controlling the short-range wireless communication unit 4 and the transceiver 5, are provided.

Each short-range wireless communication unit 4 provided in each electronic device is for transmitting and receiving various signals within a short distance by a radio signal such as radio waves or infrared rays. The short-range wireless communication unit 4 is always different during the operation of the WLAN system. It is in an on state where wireless signals can be transmitted and received between and.

Here, each electronic device in the network holds identification information (for example, an IP address, a MAC address, etc.) for identifying each other, and each identification information is registered in a memory (not shown) or the like of each electronic device, respectively. The data transmitted / received to the short range wireless communication unit 4 includes data of this identification information as destination information, so that data, commands, and the like can be transmitted only to a specific electronic device. In addition, by including the data of the identification information as the source information, it is possible to identify which electronic device the signal is sent from.

Each short-range wireless communication unit 4 is a means for transmitting / receiving a status signal indicating a state of each communication device and a means for transmitting a control delegate signal from the master communication device 1 to the slave communication device 2, and furthermore, a slave communication device. It serves as a means for transmitting a request signal from the master communication device 1 to the apparatus 2, and details thereof will be described later.

Radio waves, infrared rays, or the like can be used for the radio signals transmitted and received by the near field communication unit 4.

The transceiver 5 provided in each electronic device transmits and receives radio signals in order to communicate with various telephone apparatuses outside the WLAN system (outside the network) using a radio telephone line.

In the present invention, it is assumed that it is applied to the existing wireless telephone system. Therefore, the transmission / reception unit 4 of each electronic device in the LAN performs wireless telephone communication with the telephone apparatus outside the network through the existing host station 3 which manages the wireless telephone line, as shown in FIG. Although the detailed description is omitted, the host station 3 includes one central control station 31 and a plurality of base stations 32 (32a to 32n), and the base station 32 performs processing relating to location registration for the wireless telephone line. The central control station 31 performs processing such as ID (telephone number) management of wireless telephone lines and line connection between telephone apparatuses.

The control section 6 of each electronic device controls its short-range wireless communication section 4 and the transmission / reception section 5 while performing various processes based on the control program. Details of the control of the control unit 6 will be described later.

Although not shown in the drawings, for each electronic device, operations such as a key switch for supplying an operation input signal to the control unit 6 for operation setting of the short range wireless communication unit 4 or the transmission / reception unit 5, or for the convenience of a user. A display unit such as an LCD for displaying the input unit, the state of the electronic device, or the like is provided as a user interface. These operation input units and display units may be configured to use key switches, LCDs, or the like that accompany electronic devices, or may be configured to be remotely operated using a remote controller or the like.

In addition, since the present invention is based on the premise of network connection of various electronic devices (television receivers, video decks, personal computers, various domestic telephone products, etc.), the various functions for realizing each function of the electronic devices are provided. Means are provided.

In the present invention, one of the plurality of electronic devices in the network becomes the master communication device 1, and in order to use one wireless telephone line in common in each electronic device, the other electronic devices are slave communication devices (2; 2A). , 2B, 2C, ..., 2n). Each slave communication device 2 temporarily uses a wireless telephone line based on the control delegate signal transmitted from the short range wireless communication unit 4 of the master communication device 1.

More specifically, in the present invention, one wireless telephone line is set in the network, and therefore, the wireless telephone line is used by the transceiver 5 at least in a memory (not shown) in the master communication device 1. An ID (telephone number) for storing is stored.

Each slave communication device 2 normally turns off the transmission / reception unit 5, and receives the control delegate signal transmitted from the master communication device 1 to the slave communication device to the short-range wireless communication unit 4, thereby transmitting and receiving the transmission / reception unit. (5) is turned on so that a wireless telephone line can be used. That is, the control delegation signal is a signal that allows the transmission / reception unit 5 of the slave communication device to be turned on, and the details thereof will be described later.

Here, "off" of the transmission / reception unit 5 is a state in which the output of the position registration radio signal is prohibited to the transmission / reception unit 5 at least. For example, by prohibiting the supply of power to the transmission / reception unit 5. It can be realized. On the other hand, "on" of the transmission / reception unit 5 means that the output prohibition of the position registration radio signal is released and the radio telephone line can be used. The meaning of off and on of the transmission / reception unit 5 is commonly used by each slave communication device 2 and the master communication device 1.

In addition, as an embodiment of the present invention, the ID (telephone number) for using the wireless telephone line by the transceiver 5 is always stored only in the memory in the master communication device 1 and in the memory of the slave communication device 2. Although the configuration is not stored and the configuration in which the same ID (telephone number) is always stored in the memory of each communication device 1 and 2 can be roughly classified, in the following embodiments, the ID is the master communication device 1. The case where the configuration is always stored only in the memory within) is described.

Next, a specific control example will be described with reference to the flowchart of FIG. 2. In the initial state and the normal state of the WLAN system, only the transceiver 5 of the master communication device 1 is turned on, and each slave communication is performed. Each transceiver 5 is controlled so that the transceiver 5 of the apparatus 2 is turned off completely (step S1).

In order to make this state, the master communication device 1 performs the control which turns off the transmission / reception part 5 of each slave communication device 2 in a network via the short-range wireless communication part 4, or each slave communication device ( What is necessary is just to perform control which turns off the transmission / reception part 5 of itself automatically until 2) receives control control signal.

In the following embodiments, the slave communication apparatus 2 side automatically turns off its own transmission / reception unit 5 until the control delegate signal is received by the slave communication apparatus 2 in consideration of the possibility of communication failure of the short range wireless communication unit 4. A control example in the case of performing control to be described will be described.

In the state shown in FIG. 1 (first state), only the transceiver 5 of the master communication device 1 is turned on to register the position with respect to the base station 32 of the host station 3 (base station 32b in FIG. 1). And the call to and from the unspecified telephone apparatus outside the network is performed only by the master communication apparatus 1.

In this first state, the master communication device 1 determines from the control section 6 as to whether or not a control delegation reason to a predetermined one slave communication device in each slave communication device 2; 2A to 2n occurs ( In step S2), when it is determined that the reason for control delegation has occurred, the transmission / reception unit 5 of its own is turned off, and only the transmission / reception unit 5 of the predetermined one slave communication apparatus 2 in each slave communication apparatus is turned on. The control delegate signal is transmitted from the short range wireless communication unit 4 to the slave communication apparatus so as to switch to the second state (step S3).

Here, at the time of occurrence of the control delegation reason, in the first state, when the master communication device 1 occurs during the call-in / out waiting (in the case of outgoing control delegation described later), and unspecified outside the network with the master communication device 1. It is roughly classified into a case that occurs during communication between telephone apparatuses (in the case of call control delegation described later).

The state of each communication apparatus 1, 2 in a 2nd state is shown in FIG. As shown in Fig. 3, in the second state, only the transceiver 5 of one slave communication device 2 (slave communication device 2A in Fig. 3) that has received the control delegate signal from the master communication device 1 is turned on. The host station 3 registers the location with the base station 32b, and only the slave communication device 2A is used for incoming and outgoing calls to unspecified telephone apparatuses outside the LAN.

And in this 2nd state, it is monitored about the presence or absence of the control delegation termination reason with respect to the one slave communication apparatus 2 which performed control delegation (step S4), and when a control delegation termination reason generate | occur | produced, in FIG. Control processing for switching to the illustrated first state is performed in the master communication device 1 and its slave communication device 2 (step S5). In addition, the specific example of the reason for end of control delegation is mentioned later.

As a control for returning from the second state to the first state in step S5, the control process and the transceiver 5 to turn on / off the transceiver 5 of the slave communication device 2, which is the object of control delegation, are performed. The processing which the master communication device 1 senses that it is turned off, and the control process which turns on / off the transmission / reception part 5 of the master communication device 1 are included.

As described above, in the present invention, the normal state of the first state in which the transceiver 5 of the master communication device 1 is turned on and the transceiver 5 of each slave communication device 2 is turned off, and either slave When delegation of control to the communication device occurs, the control unit 5 of the master communication device 1 is turned off and only the transmission / receiver 5 of the predetermined one slave communication device 2 is turned on. Since each transmitting and receiving means 5 is controlled to switch the second state of the communication apparatus, only the transmitting and receiving unit 5 of one communication device is always on, so that one radio telephone line is connected to each communication device 1, 2. By using in common, it is possible to avoid simultaneous use, so that no special processing such as authentication of the host station 3 side (communication service provider side) is caused, and further, the problem of location registration is solved.

Next, with reference to FIGS. 4-12, the specific control content etc. in the WLAN system which applied this invention are demonstrated in detail.

First, from the viewpoint of the occurrence time of the above-mentioned control delegation reason (step S2 in FIG. 2) and the communication mode of the slave communication device which has received the control delegation, any one of the master communication device 1 in the waiting state for the call-in / out When one slave communication device 2 receives control delegation and enters a second state, and the slave communication device 2 makes a call to a telephone device outside the LAN, and in the first state, the master communication device 1 And communication between an unspecified telephone apparatus outside the network, which one of the slave communication apparatuses 2 receives the control delegation, enters the second state, and can be roughly established when establishing communication with the telephone apparatus and the slave communication apparatuses 2. have. Therefore, for convenience of explanation and difference in control contents, the former control delegation is called outgoing control delegation, and the latter control delegation is called incoming control delegation, and the following are distinguished and described.

FIG. 4 shows an overview of the overall system processing when any slave communication device 2 receives control delegation (outgoing control delegation) from the master communication device 1 and transmits to a telephone device outside the LAN. . In this case, in the first state (step S1) in which only the transceiver 5 of the master communication device 1 is turned on, the control unit 6 of the master communication device 1 is either slave communication device 2. Monitoring the reception of the request signal requesting transmission control delegation from the short-range wireless communication unit 4 of the master communication device 1 (step S2A), and upon receiving the request signal, the control delegation described in step S2 of FIG. Reason (outgoing control delegation reason) occurs and transmits the transmission control delegation signal from the short range wireless communication unit 4 of the master communication device 1 to the slave communication device 2, and at the same time transmits and receives the master communication device 1 The section 5 is controlled to be turned off (step S3A).

Here, the request signal includes, for example, destination information such as the MAC address described above, source information, a signal for requesting transmission control delegation, and the like.

In addition, the source control delegation signal includes, for example, destination information such as the above-described MAC address, source information, ID (telephone number) information of the master communication device 1, and the transmission / reception unit 5 of the slave communication device 2. Instructions for allowing the transmission to be made. Therefore, the slave communication apparatus 2 which receives the transmission control delegation signal in front of itself from the short range wireless communication unit 4 can use the wireless telephone line based on the ID received by turning on its own transceiver 5. Become. In addition, the on / off of the transmission / reception units 5 of the master communication device 1 and the slave communication device 2 are switched, respectively, so that the whole system is switched from the first state to the second state.

In this second state, only the transmission / reception unit 5 of one slave communication device 2 serving as the source of the request signal is turned on, and the position registration with respect to the host station 3 (base station 32b in Fig. 3) is performed. Therefore, the slave communication device 2 can be transmitted by itself without relaying the master communication device 1, and problems such as an increase in the processing burden of the host station 3 can be avoided.

When the transmission / reception unit 5 is turned on and the position registration with respect to the base station 32b is performed, the slave communication device 2 which has received the transmission control delegation returns to the other party's telephone number as the target based on the operation of the operation input unit by the user. The transmission will start.

Here, it becomes possible to apply a restriction or the like to the radiotelephone communication function of the slave communication device 2 that has received the transmission control delegation signal by a command or information included in the transmission control delegation signal.

For example, by including in the originating control delegation signal a command for inhibiting the incoming call by the transmitting and receiving unit 5 of the slave communication device, the control delegation of the origination only is set, and the originating operation of the slave communication device 2 which has received the originating control delegation. Even if a call is made from an unspecified telephone apparatus outside the network to a LAN (to the telephone number of the master communication apparatus), it is possible to reject the call and prevent the user's originating operation from interfering.

It is also possible to limit the transmission destination by the transmission / reception unit 5 of the slave communication device 2 to a predetermined range by using the transmission control delegation signal including an instruction for limiting the transmission destination of the slave communication device.

For example, in the predetermined memory of the master communication device 1, a telephone number (for example, an international call with a high call charge, a dial Q2, etc.) forbidding outgoing registration is registered, and the information of this telephone number at the time of transmission of the transmission control delegation signal. And a command to prohibit the call to the telephone number can be prevented from being transmitted to the slave communication device 2 for the predetermined telephone number.

In the second state, the control delegate end reason for the slave communication device 2 is monitored (step S4), and when it is determined that the control delegate end reason has occurred, the first state is described. The control returns to the initial state by performing the control for return (step S5).

FIG. 5 shows a slave communication device 2 receiving control delegation (incoming control delegation) from the master communication device 1 during communication by a telephone line outside the network and a wireless telephone line of the master communication device 1. The outline of processing of the whole system in the case of performing communication with the slave communication device 2 and the telephone apparatus outside the network is shown.

In this case, in the first state (step S1) in which only the transceiver 5 of the master communication device 1 is turned on, the master communication device 1 receives a call from an unspecified telephone device (source telephone device) outside the network. And the communication unit 5 start the communication (step S1A) and start communication, and in the communication state with the source telephone apparatus, the control unit 6 of the master communication apparatus 1 identifies any slave communication apparatus 2. It is determined whether or not a predetermined signal to be received has been received (step S2B).

This predetermined signal is a signal triggered to specify a slave communication device that is the subject of call control delegation, for example, a signal such as an ID indicating a slave communication device transmitted from an originating telephone apparatus (hereinafter referred to as slave ID), Operation input signals and the like for delegation of the incoming call control according to the operation of the operation input unit (key switch, etc.) of the master communication apparatus 1 based on conversations between the user of the source telephone apparatus and the user of the master communication apparatus 1; .

Here, when the master communication device 1 monitors the reception signal of the transmission / reception unit 5 for the determination of the reception of the slave ID, and the reception signal from the operation input unit for the determination of the reception of the operation input signal, good. Regarding the slave IDs, for example, with respect to the slave communication devices 2A to 2n, different numbers (e.g., 01, 02, 03 ...) are assigned as slave IDs in advance, and each slave ID is assigned to the master communication device ( The memory may be stored in correspondence with identification information such as the MAC address of each slave communication device 2A to 2n managed by 1).

And when this predetermined signal is input, the control part 6 of the master communication apparatus 1 should generate the control delegation reason (reception control delegation reason) demonstrated in step S2 of FIG. 2, and should establish communication with a source telephone apparatus. Specify one slave communication device to perform (step S2C), transmit the incoming control delegation signal from the short range wireless communication unit 4 of the master communication device 1 to the specific one slave communication device 2, and The transmission and reception section 5 is controlled to be turned off (step S3B).

Here, in the incoming control delegation signal, for example, destination information such as the above-described MAC address, source information, ID (telephone number) information of the master communication device 1, and the transceiver 5 of the slave communication device 2 are turned on. Command to allow the device to be allowed to be used. Therefore, the slave communication apparatus 2 which received the incoming call control delegation signal to the near field communication unit 4 can use the radio telephone line based on the ID received by turning on its own transceiver 5. Become. Further, the on / off of the transmission / reception units 5 of the master communication device 1 and its slave communication device 2 are switched, respectively, so that the whole system is switched from the first state to the second state, and master communication with the source telephone apparatus. The communication between the devices 1 is terminated once.

In this second state, since only the transmission / reception unit 5 of one slave communication device 2 that has received the incoming control delegation signal is turned on, the position registration with respect to the host station (base station 32b in FIG. 3) is performed. When the call is made again from the source telephone apparatus to the LAN (to the telephone number of the master communication apparatus 1), the call is transmitted / received to the slave communication apparatus 2 without transmitting the call to the master communication apparatus 1 (5). Can be directly received, and problems such as an increase in processing burden on the host station can be avoided.

The slave communication device 2 that has received the incoming control delegation signal performs processing for bringing communication to the source telephone apparatus based on the information included in the incoming control delegation signal (step S3C).

Here, it becomes possible to apply a restriction or the like to the radiotelephone communication function of the slave communication device 2 that has received the incoming control delegation signal by a command or information included in the incoming control delegation signal.

For example, by including a command to prohibit transmission by the transmission / reception section 5 of the slave communication device in the incoming control delegation signal, only the incoming call is delegated to control, and the LAN is again transferred from the source telephone device (master communication device 1). When a call is made to a phone number, the call can be quickly received by the transmission / reception unit 5 of the slave communication device 2.

For example, the incoming control delegation signal includes the telephone number information of the calling party telephone device and a command to permit incoming call only from the calling party telephone device, and the incoming communication delegation waits for the slave communication device 2 receiving the incoming call delegation. In the meantime, when a call is made from another telephone apparatus outside the LAN to the LAN, it is also possible that the slave communication apparatus 2 does not disturb the call waiting state for the originating telephone apparatus without receiving the call.

For example, the incoming control delegation signal includes the telephone number information of the calling party telephone apparatus and an instruction (or an instruction to be sent) for allowing the originating telephone number to be sent, thereby declaring the incoming control delegation. From the received slave communication device 2 to the source telephone device, a call based on the user's call operation can be executed or automatically sent.

In the second state, the control delegate end reason for the slave communication device 2 is monitored (step S4), and when it is determined that the control delegate end reason has occurred, the first state is described. The control returns to the initial state by performing the control for returning (step S5).

Next, with reference to the flowchart of FIG. 6, the control process performed by the control part 6 of the master communication apparatus 1 is demonstrated centering on the case of transmission control delegation.

The control unit 6 of the master communication device 1 controls the transceiver 5 to turn on the transceiver 5 in the initial state (step S1), and the position with respect to the host station (base station 32b in FIG. 1). Register.

Subsequently, the control unit 6 of the master communication device 1 monitors the received signal of the near field communication unit 4 and determines whether or not a request signal from the slave communication device 2 has been received (step S2A). A process of determining whether or not a call from a telephone outside the LAN has been received (received) by monitoring the reception signal of the transmission / reception unit 5 (step 13), and in front of the telephone outside the LAN by monitoring the input signal from the operation input unit. The process of determining whether or not to transmit is performed (step S14), and the determinations of step S2A, step S13, and step S14 are repeated until either of these determinations is yes.

Here, if it is determined that the request signal has been received, the process proceeds to step S15, if it is determined that there is an incoming call, the process goes to step S21, and if it is determined that the call is sent, the process proceeds to step S25.

In step S15, the control unit 6 of the master communication device 1 controls the short-range wireless communication unit 4 to transmit the transmission control delegation signal to the slave communication device 2 of the request signal transmission source, and transmits and receives its own transmission / reception unit ( The transceiver 5 is controlled so that 5) is turned off (step S16). The control unit 6 of the master communication device 1 transmits a short-range wireless communication unit to each slave communication device to transmit a status signal indicating that its own transmission / reception unit 5 is turned off when the transmission / reception unit 5 is turned off. 4) (step S17).

Thereafter, the slave communication device 2 that has received the transmission control delegation signal turns on the transmission / reception unit 5 to thereby transition from the first state to the second state.

The control unit 6 of the master communication device 1 monitors the reception signal of the short range wireless communication unit 4, specifically, a status signal sent from the slave communication device 2 which delegates originating control, and the slave communication device. The state and operation of the transmission / reception unit 5 are monitored, and whether or not the transition to the second state has been performed, whether or not the slave communication device 2 that has delegated the control has been sent or not is appropriately checked.

In this embodiment, both of the control unit 6 of the slave communication device 2 and the control unit 6 of the master communication device 1 determine whether the control delegation termination reason occurs (step S4 in FIG. 4). When the control delegation termination reason occurs, the control unit 6 of the slave communication device 2 turns off its own transmission / reception unit 5 and transmits a status signal to the communication device from the short range wireless communication unit 4. It is supposed to transmit in the future.

For this reason, the control part 6 of the master communication device 1 monitors whether the transmission / reception part 5 of the slave communication device 2 which delegated control in the 2nd state has turned off (step S18). , When the state signal indicating that the signal is turned off is received by the short range wireless communication unit 4, the control delegate 5 is turned on as the reason for the control delegation termination occurs (step S19), and the state indicating that the state is on. The short range wireless communication unit 4 is controlled to transmit a signal to each slave communication device 2A to 2n (step S20), and the process returns to the decision loop processing of steps S2A to S13 to S14.

On the other hand, when a call from a telephone device outside the LAN is received (received) by the transmission / reception unit 5, the control unit 6 of the master communication device 1 receives a status signal indicating that the call is being received (out of standby state). The short range wireless communication unit 4 is controlled to transmit to each slave communication device 2 (step S21), and various processes for establishing communication with the source telephone apparatus are performed to enter the communication state (step S22). Although the reception control delegation processing described in FIG. 5 is performed during this communication state, the processing performed when the control unit 6 of the master communication device 1 is the reception control delegation will be described later in FIG. 8.

In the communication state with the source telephone apparatus, the control unit 6 of the master communication apparatus 1 monitors the reception signal or the like of the transmitting / receiving unit 5 to determine whether or not communication with the source telephone apparatus has ended (step S23). If it is determined that the communication has ended, the short-range wireless communication unit 4 is controlled (step S24) so as to transmit a status signal to the slave communication apparatus in order to send the status signal to the slave communication device (step S24). The process returns to the judgment loop process of step S14.

In addition, when making a call from the master communication device 1 to a telephone device outside the LAN, the control unit 6 of the master communication device 1 transmits a short-range wireless signal to transmit a status signal indicating that the call is being sent (out of standby state). The communication unit 4 is controlled (step S25), and various processes for establishing communication with the other party's telephone apparatus are performed to enter the communication state (step S26).

5 can be performed even in the communication state of step S26. In this case, the process of acquiring the telephone number information of the other party's telephone apparatus to the master communication apparatus 1 (Fig. 8). Step S51) becomes unnecessary.

In the communication state of step S26, the control unit 6 of the master communication device 1 monitors the reception signal or the like of the transmission / reception unit 5 to determine whether or not communication with the other party's telephone apparatus has ended (step S27), In the case where it is determined that the communication has ended, the short range wireless communication unit 4 is controlled to transmit the status signal for that purpose (the purpose of entering the standby state again) to each slave communication device 2A to 2n (step S28), and the step The process returns to the decision loop process of steps S2A to S13 to S14.

Next, with reference to the flowchart of FIG. 7, the control process performed by the control part 6 of the slave communication apparatus 2 is demonstrated centering on the case of transmission control delegation.

The control unit 6 of the slave communication device 2 controls the transceiver 5 to turn off the transceiver 5 in the initial state when the power is applied (step S1). In this embodiment, the power consumption is reduced by prohibiting the supply of power to the transceiver 5 in step S1.

Subsequently, the control unit 6 of the slave communication device 2 monitors the reception signal of the short range wireless communication unit 4 to determine whether or not an incoming control delegate signal from the master communication device 1 has been received (step) S32), and a process (step S33) is performed to monitor whether an input signal from the operation input unit is monitored and whether a trigger signal for transmitting a request signal to the master communication device 1 is input (step S33). The determination of steps S32 and S33 is repeated until yes.

Here, in the case where it is determined that the incoming control delegation signal has been received, the incoming control delegation process described later in FIG. 9 is performed, and when it is determined that there is an input of the trigger signal, the flow proceeds to step S34.

When the trigger signal is input, the control unit 6 of the slave communication device 2 checks the received signal of the short range wireless communication unit 4, specifically, the status signal from the master communication device 1, and checks the master communication device ( It is judged whether 1) is a standby state (the decision loop state of steps S2A to S14 in FIG. 6), and if it is not in the standby state, the master communication device 1 is using a wireless telephone line or another slave communication. Delegation of control to the apparatus 2 is performed, and the display unit is displayed to display an error (step S35), and the process returns to the decision loop of steps S32 and S33.

On the other hand, when the master communication device 1 is in the standby state, the control unit 6 of the slave communication device 2 controls the near field communication unit 4 to transmit a request signal to the master communication device 1 (step) S36) By monitoring the received signal of the near field communication unit 4, the apparatus waits until the outgoing control delegation signal from the master communication device 1 is received (step S37). When receiving the transmission control delegation signal, the control unit 6 of the slave communication device 2 extracts data (various information or commands) included in the transmission control delegation signal and appropriately stores the memory (RAM, etc. in the control unit 6). ] Is stored (step S38).

Subsequently, the control unit 6 of the slave communication device 2 monitors the reception signal (status signal from the master communication device 1) of the short range wireless communication unit 4 and transmits and receives the transmission / reception unit 5 of the master communication device 1. Wait until) is turned off (step S39), and when turned off, the transmitter / receiver 5 is controlled to turn on its own transceiver 5 (step S40), indicating that its transceiver 5 is on. The short-range wireless communication unit 4 is controlled to transmit the indicated status signal to the master communication device 1 and the other slave communication device 2 (step S41).

Then, the control unit 6 of the slave communication device 2 monitors the input signal from the operation input unit and determines whether or not a trigger signal for transmitting to a counterpart telephone apparatus outside the LAN is input (step S42). If it is input, the transmitter / receiver 5 is controlled to transmit to the other party's telephone apparatus to establish communication (step S44).

In addition, during communication with the other party's telephone apparatus, the control unit 6 of the slave communication apparatus 2 monitors the reception signal or the like of the transmission / reception unit 5 and determines whether or not the communication is terminated (step S45). In the case of the determination, it is assumed that the reason for the termination of control delegation in step S4 of FIG. 4 has occurred, the transmission / reception unit 5 is turned off, and the processing for erasing and initializing various information or instructions stored in the memory in step S38 is performed. (Step S46).

Then, when the transceiver 5 is turned off, the controller 6 of the slave communication device 2 sends a status signal indicating that the transceiver 5 is turned off to the master communication device 1 and the other slave communication devices 2. The short range wireless communication unit 4 is controlled to transmit in the future (step S47), and the process returns to the decision loop of steps S32 and S33.

On the other hand, the control unit 6 of the slave communication device 2 monitors whether or not a predetermined time has elapsed while a trigger signal for transmitting to a counterpart telephone apparatus outside the LAN is not input (step S43), and the predetermined time has elapsed. In one case, it is assumed that the reason for the termination of control delegation in step S4 of FIG. 4 has occurred, and the above-described processing of steps S46 and S7 is performed to return to the decision loop of steps S32 and S33.

In the present embodiment, by providing the processing in step S43, the slave communication device 2, which has been delegated the originating control, does not transmit forever and does not return to the first state, but the transmission / reception unit of the master communication device 1 5) It becomes possible to prevent the situation of not using for a long time. In addition, in this embodiment, after the transmission control delegation, the slave communication device 2 itself makes a determination as to whether or not a control delegation termination reason has occurred and performs control for switching the transmission / reception unit 5 from on to off. The processing burden on the master communication device 1 side is reduced, and furthermore, even if the communication state with the master communication device 1 by the short range wireless communication unit 4 is unsuccessful after the transmission control delegation, for example. It becomes possible (2) to turn off the transceiver 5 by itself.

FIG. 10 shows a signal flow and the like in the case where the master communication device 1 delegates outgoing control to the slave communication device 2 based on the processing in FIG. 6 and FIG. 7.

As can be seen in FIG. 10, in the present embodiment, the slave, which has been delegated outgoing control by waiting for the transceiver 5 of the master communication device 1 to be turned off when switching from the first state to the second state. The transmission / reception section 5 of the communication device 2 is turned on, and when the transition from the second state to the first state is made, the transmission / reception section 5 of the slave communication device 2 which has received the transmission control delegation is turned off. Since each transceiver 5 is controlled so that the transceiver 5 of the master communication device 1 is turned on, the situation where two or more transceivers 5 are turned on at the same time can be avoided. The state and the second state are smoothly switched.

Next, with reference to the flowchart of FIG. 8, the control process regarding incoming control delegation which the control part 6 of the master communication apparatus 1 performs is demonstrated. In the flowchart of Fig. 8, steps S51 to S54 are performed in a communication state (step S12 in Fig. 6) with an out-of-LAN source telephone apparatus, and steps S55 to S59 are the first state and the second. The processing for switching the state is shown. In addition, the process corresponding to the process in FIG. 6 is shown with the same step number.

The control unit 6 of the master communication device 1 stores the telephone number of the source telephone apparatus in an internal memory or the like during communication connection with the source telephone apparatus or during communication (step S51).

In addition, the control unit 6 of the master communication device 1 monitors the reception signal of the transmission / reception unit 5 while communicating with the source telephone apparatus, and designates a slave communication apparatus from the source telephone apparatus (for example, the slave ID described above). ) Is transmitted (step S52) and whether or not communication with the source telephone apparatus is terminated (step S23 in FIG. 6), and if communication is terminated without receiving a signal specifying the slave communication apparatus, FIG. Is transmitted from the short range wireless communication unit 4 to the standby state (steps S2A to S14 in FIG. 6), and the signal for designating the slave communication device is received by the transceiver 5 at step S24 of FIG. The flow proceeds to step S53.

In step S53, the control unit 6 of the master communication device 1 controls the short-range wireless communication unit 4 to transmit the incoming control delegation signal to the designated slave communication device 2, and at the same time, the transmission / reception unit 5 It is determined whether or not communication with the source telephone apparatus is terminated by monitoring the received signal of (step S54). When communication with the source telephone apparatus is terminated, the transmission / reception unit 5 is turned off (step S55) to indicate that it is off. The status signal is transmitted from the short range wireless communication unit 4 to each slave communication device 2 (step S56).

Thereafter, the slave communication device 2 that has received the incoming control delegation signal turns on the transceiver 5 so as to transition from the first state to the second state, so that the control unit 6 of the master communication device 1 Monitors a reception signal of the short range wireless communication unit 4, specifically, a status signal transmitted from the slave communication device 2 that has delegated the incoming control, and monitors the state or operation of the transmission / reception unit 5 of the slave communication device. Then, it is appropriately checked whether or not the transition to the second state has been performed, whether or not communication has been established with the slave communication device 2 and the source telephone apparatus delegated to control.

In this embodiment, both of the control unit 6 of the slave communication device 2 and the control unit 6 of the master communication device 1 determine whether or not the control delegation termination reason has occurred (step S4 in FIG. 4). In the configuration, when the control delegation termination reason occurs, the control unit 6 of the slave communication device 2 turns off its own transmission / reception unit 5 and transmits a status signal to the effect from the short range wireless communication unit 4. have.

For this reason, the control part 6 of the master communication device 1 monitors whether the transmission / reception part 5 of the slave communication device 2 which delegated control was off in the 2nd state (step S57), When the state signal indicating that the signal is turned off is received by the short range wireless communication unit 4, it is controlled to turn on its own transmission / reception unit 5 on the assumption that the end of control delegation has occurred (step S58), and a status signal indicating that it is on. Control the short-range wireless communication unit 4 so as to transmit to the slave communication apparatuses (step S59), and return to the decision loop (standby state) of steps S2A to S13 to S14 in FIG.

As can be seen in comparison with Fig. 6, the basic processing (steps S55 to S59) after completion of communication with the source telephone apparatus in incoming call control delegation is steps S16 to S20 in Fig. 6 in outgoing control delegation. Since the same processing is realized as described above, the program can be simplified.

In addition, the process of FIG. 8 can be performed also when calling from the master communication apparatus 1 to the telephone apparatus outside a LAN (step S26 of FIG. 6), In this case, a call originating telephone apparatus is carried out in a counterpart telephone apparatus. Therefore, step S23 may be read into step S27 and step S28, respectively.

Next, with reference to the flowchart of FIG. 9, the control process which the control part 6 of the slave communication apparatus 2 performs at the time of call control delegation is demonstrated. In addition, in FIG. 9, the control process of the control part 6 of the slave communication apparatus 2 after having determined that the incoming control delegation signal was received in step S32A of FIG. 7 is shown.

When the control unit 6 of the slave communication device 2 receives the incoming control delegation signal from the short range wireless communication unit 4 (step S71), the controller 6 extracts data (various information or commands) included in the incoming control delegation signal and stores an appropriate memory. (RAM in the control unit 6, etc.) is stored (step S72).

Subsequently, the control unit 6 of the slave communication device 2 monitors the reception signal (status signal from the master communication device 1) of the short range wireless communication unit 4 and transmits and receives the transmission and reception unit 5 of the master communication device 1. Wait until) is turned off (step S73), and when off, the transceiver 5 is controlled to turn on its own transceiver 5 on the basis of the extracted data (step S74), and its own transceiver ( The short-range wireless communication unit 4 is controlled to transmit a status signal indicating that 5) is on to the master communication device 1 and the other slave communication device 2 (step S75).

As a result, the entire system is switched from the first state to the second state, and the position registration to the host station (base station) is performed by the transmitting and receiving unit 5 of the slave communication device 2.

Then, the control unit 6 of the slave communication device 2 monitors the reception signal of the transmission / reception unit 5 to determine whether there is an incoming call (step S76), and when a signal indicating the incoming call is received, automatically or The transmission and reception unit 5 is controlled to wait for the operation of the operation input unit to connect communication to the source telephone apparatus (step S78).

In addition, during communication with the source telephone apparatus, the control section 6 of the slave communication apparatus 2 monitors the reception signal of the transmission / reception section 5 and the like to determine whether or not the communication is terminated (step S79). In the case of the determination, it is assumed that the reason for the control delegation termination in step S4 in FIG. 4 has occurred, the transmission / reception unit 5 is turned off, and the processing for erasing various information or instructions stored in the memory in the previous step S72 is performed. (Step S80).

When the transmission / reception unit 5 is turned off, the control unit 6 of the slave communication device 2 transmits the state signal to the master communication device 1 and the other slave communication device 2 so as to transmit the short-range wireless communication unit ( 4) (step S81), the process returns to the decision loop of step S32 and step S33 in FIG.

On the other hand, while a signal indicating an incoming call is not received by the transmission / reception section 5, the control section 6 of the slave communication device 2 monitors whether a predetermined time has elapsed (step S77), and the predetermined time has elapsed. In this case, after the above-described processing of step S80 and step S81 is assumed that the control delegation termination reason in step S4 of FIG. 4 has occurred, the process returns to the decision loop of step S32 and step S33 in FIG.

In the present embodiment, according to this processing step S77, a signal indicating an incoming call is not received by the transmitting / receiving unit 5 due to, for example, a failure on the source telephone apparatus or the host station 3 side, and so on, without returning to the first state. This can prevent the situation where the transceiver 5 of the master communication device 1 cannot be used for a long time.

In addition, in the present embodiment, after the incoming control delegation, the slave communication device 2 itself makes a determination as to whether or not a control delegation termination reason has occurred and performs control to switch the transceiver 5 on and off. The processing burden on the master communication device 1 side is reduced, and furthermore, even if the communication state with the master communication device 1 by the short range wireless communication unit 4 is unsuccessful after the incoming call control delegation, for example, the slave communication device. (2) it becomes possible to turn off the transceiver 5 automatically.

FIG. 11 shows a signal flow and the like in the case where the master communication device 1 delegates incoming control to the slave communication device 2 based on the processing in FIG. 8 and FIG. 9.

As can be seen from FIG. 11, in the present embodiment, the slave which has received the call control delegation by waiting for the transceiver 5 of the master communication device 1 to be turned off when switching from the first state to the second state. The transmission / reception section 5 of the communication device 2 is turned on, and upon switching from the second state to the first state, the transmission / reception section 5 of the slave communication device 2 which has received the call control delegation is turned off. Since each transceiver 5 is controlled so that the transceiver 5 of the master communication device 1 is turned on, the situation where two or more transceivers 5 are turned on at the same time can be avoided. The transition between the state and the second state is smoothly performed.

In the above-described embodiment, a configuration in which an ID (telephone number) for using a wireless telephone line is set only in the master communication device 1 and not in the slave communication device 2 has been described, but each communication device 1, A configuration in which the same ID (telephone number) is set in 2), that is, the configuration is always stored in the memory of the slave communication device 2 or the like.

In this case, when transmitting the control delegation signal to the slave communication device 2 on the master communication device 1 side, there is no need to include the ID of the radiotelephone line.

In addition, in the above-described embodiment, the case where the master communication device 1 receives the request signal from the slave communication device 2 has been described with respect to the occurrence of the originating control delegation reason, but is not limited thereto. In the state where the master communication device 1 is in the call-in / out standby state in the state 1, any slave communication device may be specified by the operation input unit of the master communication device 1 to perform operation input for transmission control delegation. Reasons for delegation may occur.

FIG. 12 shows a specific example in which the above-described master communication device 1 and slave communication device 2 are applied to various electronic devices. In the example of FIG. 12, a telephone with a fixed facsimile is used as the master communication device 1, and a personal computer 2A, a television receiver 2B, and a video deck 2C are used as the slave communication device 2, respectively. An example of a WLAN in which these are network-connected to each other is shown.

When a wireless LAN is arranged in this way, a telephone with a fax, which is usually the master communication device 1, performs wireless telephone communication with a telephone device outside the LAN, and if necessary, the master communication device 1 or a telephone outside the LAN is connected. By performing the above-mentioned incoming control delegation based on the operation of the operation input unit or the like, communication connection between the telephone apparatus and the slave communication apparatus 2 is enabled. In addition, the above-described transmission control delegation is performed on the basis of the operation of the operation input unit of the slave communication device 2, and the slave communication device 2 alone transmits to the telephone device outside the LAN and through the host station 3. It is possible to establish wireless telephone communication.

Thus, for example, when a large amount of data that cannot be received by the master communication device 1 (telephone with a fax) from the server device outside the LAN as the source telephone device is transmitted via the host station 3 to the wireless telephone line, Receive the data to the slave communication device 2 such as the personal computer 2A and display or download the data, or receive the video data for the VOD (video on demand) from the television receiver 2B, or the video deck. Various methods of recording in (2C) are possible.

Since the present invention is configured as described above, it is possible for each slave communication device to perform wireless telephone communication via a host station independently without relaying the master communication device while using one wireless telephone line. It is possible to provide a basic configuration, a control method, a control program, and the like for a WLAN system that does not require special processing such as authentication at the station side, which is very useful in industry.
