Next, the operation of the above configuration will be described.
The voice signal of the other party from the telephone line is the telephone network 1
The signal processing is performed in the order of 0, the modulation circuit 21, and the wireless transmission circuit 8, and communication is performed from the base station 1 to the mobile station 2 through the radio wave (wireless line 3) from the antenna 13. This radio wave is received by the radio reception circuit 7 from the antenna 14 of the mobile station 2, then demodulated by the demodulation circuit 20, amplified by the receiver drive circuit 11, and output to the receiver 16.

On the contrary, the voice signal of the transmitted voice inputted from the microphone 17 is processed by the amplifier 12, the modulation circuit 22 and the radio transmission circuit 9, and is transmitted as a radio wave from the antenna 14 through the radio line 3 to the base station from the mobile station 2. 1 is communicated.
This radio wave is transmitted from the antenna 13 of the base station 1 to the wireless reception circuit 6
Is received by the telephone circuit 10 and demodulated by the demodulation circuit 19.
Output to the telephone line.

As described above, in the above-mentioned conventional example, the wireless line 3 is used for the communication of both voice signals.

In the data communication from the base station 1 to the mobile station 2, after the signal is inputted from the control circuit 4 to the modulation circuit 21 and modulated, the signal is transmitted via the wireless transmission circuit 8 to the antenna 13 to the wireless line 3. Then, it is received by the radio reception circuit 7 from the antenna 14 of the mobile station 2, demodulated by the demodulation circuit 20, and then communicated to the control circuit 5 of the mobile station 2.

For this reason, the base station 1 and the mobile station 2 respectively assign the same calling code to the ID memory 23,
The data is stored in 24 and is transmitted prior to communication to authenticate each other to prevent erroneous connection with other cordless telephone devices.

[0009]

However, the above-mentioned conventional cordless telephone device has the following problems.

(1) The cordless telephone device stores the same calling code in each ID memory in the base station connected to the telephone line and the mobile station, and authenticates the communication at the start of communication to make a match. You can only communicate with each other. Then, when a plurality of telephone lines are installed in the same home or the like and a cordless telephone device is connected to each telephone line, each mobile station is restricted in operation for each telephone line. Therefore, a different mobile station must be used for each telephone line, which is very inconvenient.

(2) Similarly, when a plurality of telephone lines are installed in the same home or the like and a cordless telephone device is connected to each telephone line and a different line service is provided for each telephone line, cordless When performing a call operation to a telephone line in a mobile station of a telephone device, a person needs to select the mobile station. As an example, when some of the lines are call-only lines, it is necessary to find a mobile station that can be used for calling, and the mobile station must be selected and used while paying attention to the service content of the connected line.

(3) Similarly, a plurality of telephone lines are installed in the same home or the like, and a cordless telephone device is connected to each telephone line, and each telephone line is supported when receiving an incoming call from the telephone line. When there is an incoming call at a mobile station that has been called, when there is no person near the incoming mobile station, or when it is not possible to answer immediately even if there is, a person who can answer near the mobile station on the other telephone line side is available. Even if you are there, you cannot answer the above because you cannot know the incoming call.

(4) Similarly, a plurality of telephone lines are installed in the same home or the like, and a cordless telephone device is connected to each telephone line. When receiving an incoming call from the telephone line, the telephone line side is moved. In the case where the station cannot operate due to battery exhaustion or the like, similarly to the above (3), the mobile station on the side connected to the other telephone line is inconvenient because it cannot receive or respond to incoming calls.

(5) Similarly, a plurality of telephone lines are installed in the same household or the like, and a cordless telephone device is connected to each telephone line. When receiving a call from the telephone line, the base station is connected to the base station. Add only the registered call code,
Send the mobile station call signal. Therefore, even if a mobile station of another cordless telephone device connected to another telephone line has a different function, this function cannot be utilized.
As an example, when a mobile station or the like having a function of notifying an incoming call by light instead of sound is required, such a cordless telephone device must be purchased for the number of telephone lines.

(6) When different cordless telephone devices are installed on a plurality of telephone lines, transfer between mobile stations connected to these different devices cannot be performed.

(7) As in the case of (6) above, a call between mobile stations connected to different devices cannot be performed.

(8) When a plurality of cordless telephone devices are used in the vicinity, the base stations are asynchronous with each other during simultaneous incoming call from the telephone line and simultaneous call operation from the mobile station. In some cases, data communication may collide, and incoming calls cannot be made, resulting in communication failure.

(9) In a conventional cordless telephone device, however, a plurality of telephone lines are accommodated in one base station from the beginning, and an incoming call from each telephone line is received by each mobile station with a single call code. Is also on sale, which provides a mobile station that can be commonly used for multiple telephone lines.
It is also possible to solve some of the above problems. However, it is necessary to purchase a product with a sufficient number of lines in advance in anticipation of additional telephone lines in the future, and it is uneconomical including the case where more than the planned number of lines is required.

(10) Further, even in the case of the product described in (9) above, when the accommodation ports of a plurality of telephone lines are distant from each other, such as in a two-family house or a store-combined house, etc. However, wiring work is required, and the ease of installation, which is a feature of the cordless telephone device, is impaired.

The present invention is to solve the above problems, and provides a mobile station which can be commonly connected to a plurality of base stations connected to a plurality of telephone lines ((1)) to provide a single mobile station. A mobile station can connect to multiple telephone lines with different service contents to make a call, and at the same time, set the priority order of which telephone line to connect to ((2)), and receive calls from multiple telephone lines. On the other hand, any mobile station can acknowledge the incoming call and respond to it ((3)). Even if the mobile station connected to the base station receiving the incoming call cannot receive the incoming call due to the dead battery, other mobile stations can receive the incoming call ((( 4)), even if each mobile station has a different function, it exerts each function for incoming calls from any telephone line ((5)), and is a mobile station of a cordless telephone device connected to a plurality of telephone lines. Can be transferred between mobile stations ((6)), and similarly, calls between mobile stations are possible. ((7)), excellent cordless telephone device that can be operated reliably and reliably during simultaneous incoming and outgoing operations ((8)), economical ((9)), and easy to install ((10)) The purpose is to provide.

5 is an operation key for the base station 1, 16 is a receiver, 17 is a microphone, 18 is an operation key for the mobile station 2, 19 is a demodulation circuit for the base station 1, 20 is a demodulation circuit for the mobile station 2, and 21 is for the base station 1. A modulation circuit, 22 is a modulation circuit of the mobile station 2.

23 is the base station 1, 25 is the base station 1 ',
An ID memory 24 stores the calling code of the mobile station 2. ID memory 23, 25 of base station 1, 1 '
The call codes "A" and "B" are stored in the pair.
A priority order is set for the plurality of call codes, and the priority order is higher for the call codes on the left side of the drawing. Similarly, a plurality of calling codes “A”, “B”, “C” ... “N” are stored in the ID memory 24 of the mobile station 2, and the left one has a higher priority order. These N call codes correspond to N base stations.
Then, the control circuits 4 and 5 operate by using the calling code having the highest priority.

Next, the operation of the above configuration will be described. (1) An incoming signal from the telephone line is input to the control circuit 4 from the telephone line network 10 in both the base stations 1 and 1 '. Then, the calling code stored in the ID memory 23 or 25 is added to the transmission data for notifying the mobile station 2 of the incoming signal to assemble the signal. After that, the signal is modulated by the modulation circuit 21 and becomes a radio wave from the radio circuit 8. Then, the ring tone is received from the antenna 13 via the radio station 3 and from the antenna 14 of the mobile station 2 by the radio receiving station circuit 7, demodulated by the demodulation circuit 20 and notified to the control circuit 5 to notify the user of the incoming call. And so on. At this time, when the incoming call is received from the base station 1, the calling code “A” is sent.
Then, the call code "B" sent from the base station 1'is stored in the ID memory of the mobile station 2 and can be authenticated. Therefore, even when an incoming call is received from one of the base stations 1 and 1 ', one mobile station 2 can perform the incoming call display response operation. That is, as an example, in a two-family house, when one household goes out and the other household is requested to make an unattended telephone call, it is not necessary to use a different mobile station for each telephone line. , You can immediately respond to incoming calls from either telephone line.

On the other hand, when the mobile station 2 makes a call,
The operation key 18 is operated. As a result, the control circuit 5 which has received the calling operation information outputs a calling signal in which the calling code stored in the ID memory 24 is added to the calling data to the modulation circuit 22. Then, the signal is transmitted from the wireless transmission circuit 9 via the antenna 14 to the wireless line 3 and is transmitted.
Or reach 1 '. The base station 1 or 1'is the demodulation circuit 1
The telephone line is captured by the calling data input from 9 to the control circuit 4.

When connecting the wireless line 3, the base station 1,
The control circuit 4 of 1 ′ compares the call code stored in the ID memory 23 or 25 with the received call code, and if the call code is verified to be the same,
After that, the wireless line 3 is formed and the incoming call operation, the answer operation and the call operation are started. If it's authenticated as a different call code,
The operation returns to the waiting operation without forming the wireless line 3. At this time, the calling code stored in the ID memories 23 and 25 of the base stations 1 and 1'is the ID memory 2 shown in FIG.
The contents of the first blocks 3 and 25 are different, as referred to as “A” and “B”, respectively. In order to connect to a base station having these different calling codes, a plurality of calling codes are stored in the ID memory 24 of the mobile station 2 so that they can be selected.

When the mobile station 2 makes a call, the I of the mobile station 2
Of the calling codes stored in the D memory, the calling code of the base station 1 or 1'of the other party to call and connect to is selected and added to the calling data, so that the target base station 1 or 1 ' Can only be connected to.

(2) In the above (1), when calling from the mobile station 2, the calling code added to the calling signal can be selected in advance according to the usage pattern of the user's telephone line. The priority order shall be set to the call code of. As a result, the operation of selecting the calling code of the base station corresponding to the telephone line used for each calling operation is omitted.

The priority order of the calling codes is set by the storage block setting in the ID memory. In the embodiment of FIG. 1, "A" is given the highest priority in the ID memory 24 and is transmitted first, so that the base station 1 side is selected first. If the base station 1 cannot be selected because it is being used by another mobile station or the like, the mobile station 2 cannot receive the capture response signal from the base station 1 or the mobile station 2 receives the non-capture signal. It is judged that calling to 1 is impossible. Then, after that, the call signal to which the second call code "B" is added is transmitted, and the base station 1'is selected.

(3) In the above (2), the mobile station 2 has I calling codes corresponding to a plurality of base stations 1, 1 '... 1 ^n.
It is stored in the D memory 24 as A, B, and C to n. When the mobile station 2 receives a connection request from a plurality of base stations 1, 1 '... 1 ⁿ , the mobile station 2 compares the call request with the call code of the content of the call code ID memory 24 for each base station, and at the same time, Using the authenticated priority order as it is, in the case of FIG. 1, the call code “A” is given the highest priority, and the call code “A” is added to the response signal to add the modulation circuit 22, the wireless transmission circuit 9 and the antenna 14. Sent via. As a result, the base station 1 corresponding to the calling code “A” receives and demodulates via the antenna 13, the wireless reception circuit 6, the demodulation circuit 19 and the control circuit 4, and when the matching of the calling codes is observed, the connection operation is performed. Move. The other base station (base station 1'in FIG. 1) cannot receive the call code "B" of its own station and cannot connect, and returns to standby or shifts to another connection operation. Thus, even if there are multiple connection requests due to simultaneous incoming calls, the mobile station 2 connects only to the base station 1 designated in the priority order of the calling codes set in the ID memory 24 in advance, and is stable. Since the above-mentioned operation is performed and the user does not need a selection operation request in the congestion operation state, convenience is improved.

(4) ID memory 2 of base stations 1 and 1 '
The call codes of a plurality of mobile stations (only 2 is shown in FIG. 1) can be registered and stored in 3, 25, and the above (1)
The conveniences (3) to (3) are realized between a plurality of base stations and mobile stations. As a result, as in the conventional case, a plurality of one cordless telephone devices each including the base station 1 and the mobile station 2 having the original parent-child relationship paired with the same call code are installed, each cordless telephone device is installed. This enables connection and communication not only between the base station 1 and the mobile station 2 of the telephone device but also between the base station and the mobile station extending between cordless telephone devices.

(5) When a plurality of cordless telephone devices are installed and the function levels of the respective devices are different, the function information indicating the function level is stored in the ID memories 23, 24, which store the calling code. It is stored together with 25. Then, prior to the communication, in the authentication operation of the call code exchanged as described above, the function information is sent at the same time as the call code is sent, and the control circuits 4 and 5 judge the function level of the other party to be connected, The operation is adapted to each function.

(6) In the cordless telephone having the internal structure shown in FIG. 1, the related operation between the plurality of base stations and the mobile station will be described with reference to FIG.

In FIG. 2, 1 and 1'denominate base stations and 2-
1, 2-2 and 2-3 are mobile stations, and 3-1 to 3-5 are radio lines for connecting the base stations 1 and 1 ′ and the mobile stations 2-1 to 2-3 to make a call. .. In this embodiment, there are two base stations.
The explanation is for the case where there are three mobile stations and three mobile stations, but the basic operation is the same even if the number of each increases or decreases.

Different call codes are stored in the ID memories (corresponding to 23 and 25 in FIG. 1) built in the base station 1 and the base station 1 '. The ID code (corresponding to 24 in FIG. 1) of the mobile station 2-1 stores the same call code as that of the base station 1, and the mobile station 2-3 stores the same call code as that of the base station 1 '. As a result, the mobile station 2-1 is exclusively paired with the base station 1 and the mobile station 2-3 is exclusively paired with the base station 1 '. Two sets of cordless telephone devices thus paired are installed in one residence or store. In the ID memory of the mobile station 2-2, the calling codes of both the base station 1 and the base station 1'are stored, and as described in (1) above, it is possible to make a connection call with both the base stations 1 and 1 '. It is in.

At this time, from the mobile station 2-1 to the wireless line 3-
At 1, the base station 1 transmits a signal for designating communication to the mobile station 2-3. The call code "A" of the base station 1 is added to this transmission. The base station 1 receiving this signal communicates with the mobile station 2-2 via the wireless line 3-3.
The mobile station 2-2 determines that the notification should go through the base station 1 ', replaces the call code portion with the call code "B" of the base station 1', and communicates via the wireless line 3-4. When this is received by the base station 1 ', the final notification destination is the mobile station 2-
3 is added, the calling code “B” of the base station 1 ′ is added via the wireless line 3-2, and the mobile station 2-3 is added.
Communicate to. As a result of the above, by intermediating the mobile station 2-2 from the mobile station 2-1 connected to the base station 1 to the mobile station 2-3 connected to the base station 1 ′ having a different calling code, information of Can be transferred. For example, in an actual use state, an incoming call received by the mobile station 2-1 on the telephone line 1 of the base station 1 can be transferred to the mobile station 2-3 connected to another base station 1 '.

(7) As described in (6) above, the notification between the dedicated mobile stations 2-1 and 2-3 of the base stations 1 and 1'having different call codes "A" and "B" is performed. The call code "A" is added to the signal indicating the designation, and not only the call received on the telephone line of the base station 1 is transferred to the mobile station 2-3 on the base station 1'side, but also the call is transferred in the opposite direction. By doing so, the call can be made. That is, in the process of communication from the mobile station 2-1 to the mobile station 2-3 in (6) above, the mobile station 2-2, which acts as an intermediary, calls the call code of the call destination (here, the base station 1 ' In the state where "B") is added, the base station 1 is notified via the wireless line 3-4, and the content is received by the mobile station 2-3 via the wireless line 3-2.
Then, this time, the calling code from the mobile station 2-3 is obtained as "A" of the base station 1, and the station line acquisition signal is transmitted. This signal is directly received by the base station 1 via the wireless line 3-5, and a call is ready.

(8) When two cordless telephones as shown in FIG. 2 are operated at the same time, the control channel that is transmitted first becomes a problem during the connection operation, but the same as (7) above. In addition, if the base stations 1 and 1'having different calling codes are notified of each other's states via an intervening mobile station such as the mobile station 2-2 that stores the calling codes of the two, a wireless link is established. It is possible to avoid collision of control 4 channels. For example, when there is an incoming call to the telephone line 1 and the telephone line 2 at the same time, the incoming call operation is not immediately started, but the incoming call to the other mobile station 1 ′ is made by the own station 1 via the mobile station 2-2 in advance. Notify that the operation will be started. The mobile station 2-2 has I
As described in (2) above, since the priority order is designated for each calling code in the D memory, the notification is given priority from the base station 1 having a higher priority order and the contents are transmitted to the base station 1 '. It The base station 1'is informed of the possibility of collision with the base station 1 and can temporarily suspend the incoming call operation to prevent the collision of the wireless line.

[0056]

As is apparent from the above description, the present invention has the following advantages.
It has the following effects.

Since an incoming call from a plurality of base stations having different calling codes can be known by one mobile station, on the other hand, one mobile station can be connected to a telephone line connected to a plurality of base stations. , Operate with different mobile stations for each telephone line,
Convenience is improved without having to make a call (the invention of claim 1, the problem (1)).

Even if a plurality of telephone lines having different service contents are accommodated in base stations having different calling codes by using a plurality of cordless telephone devices, one mobile station can access a target telephone line. It is possible to easily connect and make a call (the invention of claim 1, problem (2)). At the same time, if the base station that is going to be used is in use, the base station is automatically connected to the next base station specified in the set priority order, and the operability for the user can be improved (the invention of claim 2). ).

Since any mobile station can know and respond to incoming calls from a plurality of telephone lines, that is, incoming calls from a plurality of base stations, convenience is improved (the invention of claim 3).
Challenge (3)). Further, it is economical because it is not necessary to purchase a cordless telephone device having a capacity for a telephone line which will be required in the future from the beginning, and the necessary amount can be added in a timely manner (problem (9)).

Even if the mobile station having the same calling code as the base station that received the call cannot receive the call because the battery has run out,
Since the mobile station connected to another base station can know the incoming call (problem (4)), the incoming call will not be missed.

Since the ID memory of the base station can store a plurality of calling codes, the above effect can be achieved between a plurality of base stations and mobile stations (the invention of claim 4).

Since different functions can be utilized depending on the mobile station (the invention of claim 5 and problem (5)), even if the functions are different, the basic operation part can be operated without any trouble, and the cordless telephone device to be sequentially purchased. There is no limit to the function.

Since it is possible to communicate between mobile stations of different cordless telephone devices connected to a plurality of telephone lines (the invention of claim 6 and problem (6)), the convenience is improved.

Furthermore, the mobile station that has received the transfer can capture the telephone line of the call destination and make a call (the invention of claim 7, problem (7)). Therefore, it is not necessary to go to the place where another mobile station exists.

Even when receiving calls from a plurality of telephone lines at the same time and making calls from a plurality of mobile stations at the same time, it is possible to control the transmission to the wireless lines from the plurality of base stations mutually, so that stable and reliable operation can be achieved. It can operate (the invention of claim 8 and problem (8)).

Further, the wiring work is unnecessary as compared with the case where a plurality of telephone lines are accommodated in one base station like the conventional products. That is, even when the accommodation openings of a plurality of telephone lines are separated, the above effect can be obtained by the wireless line without changing the wiring of the telephone line.
0)).

As described above, an excellent cordless telephone device can be provided.
