In addition, a buzzer or a vibrator that emits a ringtone or the like may be provided.

The control unit 66 has a home base station storage unit 661 in which information of the home base station in which the control unit 66 is registered is registered, and a visitor base station which is registered when wireless communication with the home base station cannot be performed. The visitor base station storage unit 662 in which the information of the visitor is registered, and the data in the form input by the input / output unit 64 are converted into a data form that can be wirelessly transmitted from the wireless unit 65 to the corresponding base station, or It has a data conversion unit 663 for converting data in the wireless reception buffer 653 of the wireless unit 65 that has received the wireless reception into data in a form corresponding to the input / output unit 64. Specifically, the CPU, the ROM, and the R
It is composed of an AM and the like, and controls the input / output unit 64, the radio unit 65, and the whole slave unit.

FIG. 6 shows an example of information storage in the home base station storage section 661 and the visitor base station storage section 662 taking the slave unit 5452 as an example. Base station 515 is registered as a home base station, and base station 51 is stored in home base station storage section 661.
5, extension number "50", address "C5.50", base station call code (CS-ID) specified by ARIB recommendation "2nd generation cordless telephone system standard", and flag indicating current state “2” is stored. Similarly,
The base station 511 is registered as a visitor base station, and the extension number “10”, the address “C1.10” of the base station 511 and the calling code of the base station (CS
−ID) and a flag “1” indicating the current state are stored. Note that the storage elements are not limited to these storage elements, and other elements may be stored.

As a flag indicating the current state, "1" indicates a state in which wireless communication with the base station is possible, and "2" indicates a state in which wireless communication with the base station is disabled. The flag indicating the current communication state is determined by monitoring the radio wave transmitted by the base station by the wireless communication state determination unit 651 of the wireless unit 65 of the slave unit 5452 to determine whether communication with the base station is possible.
It is updated at a predetermined timing. Therefore, the slave 5452
By looking at the flag indicating the current state, it is possible to determine whether or not the slave unit can perform wireless communication.

Next, the operation of each device will be described with reference to the connection sequences shown in FIGS. FIG. 7 is a diagram showing an outline of a main connection sequence when a call is selected from the slave unit 5411 to the slave unit 5421 by selecting voice as a service type. In advance, the home child unit registration storage unit 633 of the base station 511
Has been registered, the flag indicating the current state is also set to "1", and the slave unit 5411 and the base station 511 are in a state in which wireless communication is possible. Similarly, the slave unit 5421 is registered in the home slave unit registration storage unit 633 of the base station 512, a flag indicating the current state is set to "1", and the slave unit 5421 and the base station 512 can perform wireless communication. It is in a state.

On the other hand, home base station storage section 6 of handset 5411
The base station 511 is registered in 61, and a flag indicating the current state is also set to "1".
At 62, no base station is registered. Similarly, base station 512 is also registered in home base station storage section 661 of handset 5421, and the flag indicating the current state is also "1".
Is set, and no base station is registered in the visitor base station storage unit 662.

Further, the base stations 511 and 512 are
They are connected by a wired network 53 according to the TCP protocol, and the system storage unit 631 of the base stations 511 and 512 stores flags indicating the wired network addresses of the base stations 511 and 512, the type of device, and the current state. , An extension number, and a calling code (CS-ID) of a base station defined in the “second generation cordless telephone system standard” recommended by ARIB. The flag indicating the current state is a state in which “1” indicating the state in which the device is turned on and communication is possible via the wired network 53 is stored.

In such a state, the slave unit 5411 makes a call to the base station 511 in a method based on the "second generation cordless telephone system standard". That is,
The slave unit 511 first wirelessly transmits a link channel establishment request to the base station 511 by a control signal, and when the base station 511 wirelessly transmits a link channel assignment, the base station 511 transmits the link channel request to the base station in the communication slot of the already allocated communication carrier. Synchronize with station 511.

After the synchronization is established, the handset 5411 wirelessly transmits to the base station 511 the extension number “21” of the handset 5421 as the communication destination and a call setting in which voice is specified as the service type, and the call is accepted by the base station 511. Then, a response to the call setting acceptance is wirelessly transmitted from the base station 511.

Next, the slave unit 5411 wirelessly transmits a secret key for authentication to the base station 511, performs a function setting (not shown), and then wirelessly receives an authentication request including a random number from the base station 511. The result of performing the authentication operation on the base station 51 using the authentication key
Transmit to 1 wirelessly. The base station 511 compares the authentication calculation result wirelessly transmitted from the handset 5411 with the calculation result of the base station 511 to determine whether the handset 5411 is valid, and if so, continues the call connection. Note that authentication or function setting in the above procedure may be omitted.

Next, the base station 511 sets the wired network address “C2.21” corresponding to the extension “21” according to the call setting contents, and converts the wirelessly received call setting contents into the form of the wired network 53. By doing
Generate a packet that can be transmitted on the wired network 53,
The data is transmitted to the address “C2.21” through the wired network 53.

The base station 512 receives the packet of the destination address "C2.21" transmitted by the base station 511, and the slave unit 5421 capable of wireless connection to the base station 512 from the destination address.
Identify the communication as addressed to it. The base station 512 determines that the wireless communication with the slave 5421 is possible by seeing that the flag indicating the current state of the home slave registration storage unit 633 is “1”. Calls are received by a method based on the "2nd generation cordless telephone system standard".

That is, the base station 512 wirelessly transmits an incoming call to the slave unit 5421 by a control signal. Upon receiving the incoming call from the base station 512, the handset 5421 wirelessly transmits a link channel establishment request to the base station 512 using a control signal, similarly to the call connection procedure between the handset 5411 and the base station 511.
When the link channel assignment is wirelessly transmitted from the base station 12, the base station 512 synchronizes with the base station 512 in the communication slot of the communication carrier already assigned.

After synchronization is established, handset 5421 wirelessly transmits an incoming call response to base station 512, and then similarly transmits a call setup to base station 512, and when this is accepted by base station 512, the base station 512 receives the call setting. The response of the call setting acceptance is wirelessly transmitted from 512. Then, secret key setting, function setting, authentication, and the like are performed in the same manner. When performing authentication, the authentication result
Only in the case of K, the call connection is continued. The secret key setting, function setting, authentication, and the like may be omitted.

Next, handset 5421 activates a ringer for notifying its user of an incoming call, and transmits a call to base station 5.
The call is wirelessly transmitted to 12. Upon wirelessly receiving the call, the base station 512 converts the contents of the wirelessly received call into data in the form of the wired network 53, sets the wired network address "C1.11" as the destination address, and transmits the packet.

The base station 511 receives the "C1.11" packet as the destination address transmitted by the base station 512, and identifies from the address that the communication is directed to the slave unit 5411 wirelessly connected to the base station 511. Then, the received call contents are converted into data in the form of wireless communication and wirelessly transmitted to the child device 5411, and a ringback tone indicating that the child device 5421 is being called is wirelessly transmitted to the child device 5411.

When the handset 5421 is off-hook manually by its own user or automatically by the handset 5421, the handset 5421 wirelessly transmits a response to the base station 512 and transmits the response to the wired network 53. As a result, a packet is transmitted from the base station 512 to the base station 511, and the base station 51
A response is wirelessly transmitted from 1 to the slave unit 5411 to establish and connect an information channel.

The wireless communication between the handset 5411 and the base station 511 and between the base station 512 and the handset 5421 conform to the "second generation cordless telephone system standard".
The transmission speed is 32 Kbps full duplex, while the wired network 53 is, for example, 10BASE-T or 10B.
Transmission speed 10 represented by Ethernet such as ASE-2
A Mbps LAN or a 100 Mbps LAN, which is half-duplex communication. However, since the transmission speed is higher than that of a wireless section, communication between base stations can be performed in real time.

FIG. 8 shows a case in which a call is made from
FIG. 3 is a diagram showing a main connection sequence in the case of performing data communication with 1. The handset 5411 makes a call to the base station 511 in a method based on the "second generation cordless telephone system standard". That is, the slave unit 5411 first wirelessly transmits a link channel establishment request to the base station 511 by a control signal, and when the base station 511 wirelessly transmits a link channel assignment, the slave unit 5411 shifts to a communication slot of a communication carrier already assigned. To synchronize with the base station 511.

After the synchronization has been established, the slave unit 5411 communicates with the base station 511
Extension number "10" and service type of 32Kbps
Base station 511
When this is received by the base station 511, the base station 511 wirelessly transmits a response to the call setting reception.

Next, the slave unit 5411 wirelessly transmits a secret key for authentication to the base station 511 and performs function setting and the like.
An authentication request including a random number is wirelessly received from the base station 511, and the result of the authentication calculation of the random number using the authentication key is wirelessly transmitted to the base station 511. The base station 511 compares the authentication calculation result wirelessly transmitted from the slave unit 5411 with the calculation result of the base station 511 to determine whether the slave unit 5411 is legitimate, and if so, continues the call connection. Note that authentication or function setting in the above procedure may be omitted.

Next, base station 511 wirelessly transmits a response to slave unit 5411, an information channel is established, and slave unit 5411 and base station 511 are connected. Next, the handset 5411 and the base station 511 communicate with the PIAFS (PHS Internet Access Forum) described in the "PIAFS Specification" recommended by the PHS Internet Access Forum, which is an industry standard procedure for transmission control procedures for 32 Kbps unrestricted digital information. In accordance with the standard, a negotiation procedure called an in-band negotiation procedure is performed to complete the PIAFS connection procedure.

When the PIAFS connection procedure is completed, "PIAFS
According to the ARQ transmission control procedure described in the “AFS specification”,
Data is wirelessly communicated between the handset 5411 and the base station 511. The slave unit 5411 sets the communication destination address “E1” and the communication source address “C1.11” at the beginning of data or the beginning of each PIAFS frame, and then wirelessly transmits the data to the base station 511.

The base station 511 sets the received communication destination address “E1” and the communication source address “C1.11”, and converts the following data into the form of the wired network 53, so that the data can be transmitted through the wired network 53. A packet is generated and transmitted to the address “E1”, that is, the device 521 via the wired network 53. In parallel, if there is data to be transmitted to the child device 5411, the device 521 puts the communication destination address "C1.
11 "and the communication source address" E1 "are set, and the packet is transmitted. The base station 511 converts the received packet data into a form of wireless communication and wirelessly transmits it to the slave unit 5411.

The wireless communication between the handset 5411 and the base station 511 conforms to the "second generation cordless telephone system standard" and the "PHS Internet Access Forum standard specification", and has a transmission rate of 29.2 Kbps.
While the full-duplex wireless communication is performed, the wired network 53 is, for example, 10BASE-T or 10BASES.
Transmission speed 10Mb represented by Ethernet such as E-2
It is a LAN of 100ps and a LAN of 100Mbps, and it is half-duplex communication, but since the transmission speed is faster than the wireless section,
Data communication between the base station 511 and the device 521 can be performed in real time.

FIG. 7 shows an example in which the extension number “21” of the slave unit 5421 of the communication destination is specified in the call setting at the time of calling of the slave unit 5411, but as shown in FIG. A similar connection can also be established by designating the base station 511 first and attaching the address "C2.21" of the slave unit 5421 of the communication destination to the head at the time of data transmission on the information channel.

As described above, between the base stations 511 to 51n and between the base stations 511 to 51n and the devices 521, 5 such as personal computers.
22 is connected only by the wired network 53, and the information terminals 55 connected to the slaves 5411 to 54nm or the slaves 5412 are connected to the devices 521 and 522 and other slaves or slaves via the base station or the wired network 53. It can communicate with other information terminals connected to the device. In addition, there is no need for switching equipment and master cluster equipment that were used in the past.Furthermore, it was not necessary to lay telephone lines that were required in parallel with the wired network in the past, reducing costs and installation work. And the installation can be facilitated.

Next, a method of registering a base station will be described. FIG. 9 is a flowchart showing a series of processing up to determining whether wireless communication with the home base station is possible in the slave unit and registering a visitor slave unit when determining that wireless communication is not possible. Is received at the same timing as the control signal transmitted intermittently by the base station as defined in the “Second Generation Cordless Telephone System Standard”.

At the reception timing of the control signal of the home base station, the slave unit holds the reception level Lh of the control signal of the home base station in the wireless communication state determination unit 651 in the slave unit radio unit 65 at S1. Then, in step S2, a comparison is made with a preset threshold level Lth, and if the reception level Lh is higher, it is determined that wireless communication with the home base station is possible.
At 3, the count value a of the number counter for counting the number of times the reception level Lh has become equal to or less than the threshold level Lth is cleared, and the process waits until the next control signal reception timing. Note that a
Is initially set to 0 in S0 as an initial value.

If the reception level Lh is equal to or lower than the threshold level Lth, the count value a of the number counter is incremented in S4, and the reception level Lh is increased in S5.
It is determined whether or not the number a of times equal to or less than th exceeds a predetermined value A. If not, the process waits until the next control signal reception timing. If the count value a of the number counter exceeds a predetermined value A, it is determined that wireless communication with the home base station is impossible, and the process of registering a base station other than the home base station as a visitor slave unit is performed. Perform

In this process, first, in S6, the slave unit continues to receive a control signal until a control signal from any base station other than the home base station is correctly received by radio. When the control signal is received, the system information such as the CS-ID of the base station is read from the content of the control signal received in S7, and the reception timing is reset according to the control signal transmitted by radio from the base station. I do.

When the reception timing is matched, a link channel establishment request is wirelessly transmitted to the base station by a control signal in S8, a communication slot of a communication carrier is allocated from the base station in S9, and the communication carrier is transmitted in S10. And synchronizes with the base station. Next, at S11, the slave unit sets the extension number, address and PS-I of the slave unit.
A registration request including D or the like is wirelessly transmitted to request the base station to register as a visitor slave.

Next, the slave unit, by wirelessly transmitting the secret key used for authentication to the base station in S12, performs function setting and the like.
At S13, an authentication request including a random number used for authentication is wirelessly received from the base station. Subsequently, the slave unit wirelessly transmits to the base station the result of performing an authentication operation on the random number wirelessly received in S14 using the authentication key. In this way, the base station compares the authentication calculation result wirelessly transmitted from the slave with the calculation result of the base station to determine whether the slave is valid, and when the base is valid, the visitor slave registration storage unit 634 Then, a predetermined information is stored, and the child device is registered as a visitor child device, and a registration reception is wirelessly transmitted to the child device. Note that authentication or function setting in the above procedure may be omitted.

Upon receiving the registration reception from the base station by radio in S15, the slave unit stores predetermined base station information in the visitor base station storage section 662 in the control section 66 in S16, and stores the base station in the visitor base station. Register as a station. When the above registration procedure is completed, the slave unit releases and disconnects the wireless channel in S17,
At 18, the operation returns to the control signal reception state of the visitor base station, and the operation for monitoring the reception level of the control signal of the visitor base station is started.

On the other hand, the base station notifies the home base station of the slave via the wired network 53 that the slave has become a visitor base station. As a result, the home base station changes the flag indicating the current state of the home slave unit in the home slave unit registration storage unit 633 in the control unit 63 to “4” and changes the base station portion of the address. For example, when the child device 5452 registers a visitor child device with the base station 511, the home base station of the child device 5452 sets the address of the child device 5452 in the home child device registration storage unit 633 in the control unit 63 to “C5.
52 ”to“ C1.52 ”. The slave unit serving as the home slave unit is registered and set in the home base station in advance, or registered when the power is turned on by the processing in the flowchart of FIG.

In FIG. 10, in a state where the slave unit 5452 is registered as a visitor slave unit in the base station 511, the slave unit 5421 to the slave unit 5
It is a figure which shows the general | schematic sequence at the time of communicating with 452. This operation is basically the same as the case of FIG. 7, except that the base station 512 is connected to the home base station 51
5 cannot communicate with the base station 511 and does not know that the visitor has been registered with the base station 511. Therefore, after authentication, the wired network address "C5.52" corresponding to the extension "52" according to the call setting contents wirelessly received from the slave 5421. By converting the call setting contents received wirelessly into the form of the wired network 53, a packet that can be transmitted through the wired network 53 is generated and transmitted to the address “C5.52” through the wired network 53.

The base station 515 receives the packet from the wired network 53 because the head of the packet address is C5. Then, the base station 515 stores the address received from the wired network 53 and the home
From the contents of 33, it is recognized that the slave unit 5452 has become the visitor base station of the base station 511, and in order to notify the base station 512 of the fact, the address of the slave unit 5452 is changed from "C5.52" to "C1.52". Is changed to the wired network 53
To notify the base station 512.

The base station 512 recognizes that the slave 5452 has become the visitor base station of the base station 511 from the address change notification of the slave 5452 received from the base station 515, and changes the wired network address to “C1.52”. , And regenerates a packet that can be transmitted on the wired network 53 corresponding to the call setting content wirelessly received, and transmits the packet to the address “C1.52” on the wired network 53. Thereafter, the same operation as in FIG. 7 is performed.

In FIG. 10, the base station 515 recognizes that the handset 5452 has become the visitor base station of the base station 511 based on the address received from the wired network 53 and the contents of the home handset registration storage unit 633. Base station 512
To notify that the address of the slave unit 5452 has been changed from "C5.52" to "C1.52"
3, the base station 515 generates a packet in which the destination address is changed to "C1.52" for the packet received from the wired network 53, and the base station 515 transmits the packet. This can be dealt with by a method of transmitting a packet to the base station 511.

As described above, the child device or the information terminal connected to the child device can communicate efficiently in all the support areas of all the base stations. That is, even if the slave or the information terminal connected to the slave moves and the wireless communication state with the home base station fluctuates, the slave continues to select the home base station to perform wireless communication, or The determination as to whether to select the base station is simplified, and the processing related to the wireless connection of the slave unit is reduced. Furthermore, even if the base station having the best wireless communication state with the slave unit is a base station other than the home base station, the slave unit selects the home base station if wireless communication with the home base station is possible. To perform unnecessary wireless communication with other base stations or unnecessary wired communication between the visitor base station and the home base station via the wired network 53 to reduce the occurrence of communication collision and communication waiting. Can be suppressed.

(Second Embodiment) This embodiment is different from the first embodiment in that
Another processing example of visitor child device registration will be described. In the case of this processing example, the child device is provided with a visitor child device registration permission input switch. If visitor child device registration permission is selected, the child device performs visitor child device registration in accordance with the flowchart shown in FIG. FIG. 11 shows the case where the visitor child device registration rejection is selected.
Is performed based on.

First, the count value a of the number counter and the count value b of the continuous number counter are set to the initial value 0 in S20. Subsequently, at the reception timing of the control signal of the home base station, the slave unit holds the reception level Lh of the control signal of the home base station in the wireless communication state determination unit 651 in the slave unit wireless unit 65 at S21. Then, in S22, the reception level Lh is compared with a preset threshold level Lth, and if the reception level Lh is higher, it is determined that wireless communication with the home base station is possible. In S23, the reception level Lh becomes equal to or lower than the threshold level Lth. Count value a of the number counter that counts the number of times
And wait until the next control signal reception timing.

If the reception level Lh is equal to or lower than the threshold level Lth, the count value a of the number counter is incremented in S24, and the reception level Lh is increased to the threshold level L in S25.
It is determined whether or not the number a of times equal to or less than th exceeds a predetermined value A. If not, the process waits until the next control signal reception timing. If the count value a of the number counter exceeds the predetermined value A, it is determined that wireless communication with the home base station is impossible, and in S26, the display unit 641 of the slave unit displays on the display unit 641 of the slave base station the communication with the home base station. Indicates that wireless communication is not possible.

Here, when the user of the slave unit selects the registration of the visitor slave unit with the visitor slave unit registration permission input switch, a search is made for the visitor base station, and the flow shifts to the flow of the registration of the visitor slave unit. Also,
When the slave user does not select the visitor slave registration with the visitor slave registration permit input switch, the home base station continuously monitors the reception level Lh of the control signal transmitted by radio, and adjusts the reception timing of the control signal of the home base station. Then, in S27, the reception level Lh of the control signal of the home base station is held in the wireless communication state determination unit 651 in the slave unit wireless unit 65. Then, in S28, the reception level Lh is compared with a preset threshold level Lth.
In S29, the count value b of the continuous number counter in which the reception level Lh has exceeded the threshold level Lth is cleared, and the process waits until the next control signal reception timing.

The reception level Lh is equal to the threshold level Lth
If it is larger, the count value b of the continuous number counter is incremented in S30, and it is determined in S31 whether the continuous number b in which the reception level Lh exceeds the threshold level Lth exceeds a predetermined value B. If the number of consecutive times b exceeds the predetermined value B, it is again determined in S32 that wireless communication with the home base station is possible, and this is displayed on the display unit 641 of the slave unit. Alternatively, the display indicating that wireless communication with the home base station is not possible is deleted.

As described above, when the slave user is clearly outside the area or when the slave user determines that the connection with the visitor base station is unnecessary, the visitor slave registration processing is performed. And the power consumption of the slave unit can be prevented from being wasted. In addition, since the address of the slave unit is added to the address of the base station, if each base station knows the extension number of the slave unit except for the slave unit that has become the visitor slave unit, the address of the slave unit and the address of the slave unit are known. The home base station address can be automatically known. Therefore, except for the home slave unit registration storage unit 633 whose address indicating the current state is “4”, there is no need to store the address, and the storage area can be reduced. That is, as the slave unit registration storage unit 501, for example, as shown in FIG. 12, a home slave unit registration storage unit 6331 in which address registration is omitted and a visitor slave unit registration storage unit 6341 in which extension number registration is omitted are formed. do it.

Thus, the slave unit registration storage unit 50 of the base station
Since the amount of data recorded in 1 can be reduced, the circuit scale can be reduced and the cost can be reduced. Also, when a slave requests a base station other than the home base station to register as a visitor slave, the visitor base station can immediately recognize the slave base station by looking at the slave network network address. The registration of the slave unit can be performed quickly and easily.
