Abstract

PURPOSE:To attain communication between slave stations relating to a different connection device not through a general subscriber telephone network by providing a common ID number in common to connection devices in one and same system and including the common ID number to a control signal from a slave station. CONSTITUTION:An ID number includes an ID 1 number and an ID 2 number. The ID 1 number is a common ID number given in common to a connection device 1(2) and a connection device 2(7), and an ID 2 number is an individual ID number given differently to the connection device 1(2) and the connection device 2(7) respectively. When a slave station desires the communication with a slave station under the control of other connection device, the ID 2 number is kept the same and the individual ID 1 number of a connection device corresponding to a slave station making a request is used to attain the communication between slave stations under the control of different connection devices not through a general subscriber telephone network (1).

Description

Description: TECHNICAL FIELD The present invention relates to a cordless telephone device, and more particularly to a connecting means between slave stations associated with different connecting devices.

[Prior Art] FIG. 4 shows an example configuration of a conventional cordless telephone device.

As shown in this figure, the connection device (2) connected to the general subscriber telephone network (1) is provided with a slave station 1 (3) and a slave station 2 (4) correspondingly. The connection device (2), the slave station 1 (3) and the slave station 2 (4) are provided with an antenna (5) and a handset (6), respectively.

FIG. 5 shows a flow of operation of the inter-slave station call in this conventional example.

In this conventional example, when the slave station 1 (3) or the slave station 2 (4) requests a connection to another slave station 2 (4) or the slave station 1 (3), the connection device (2 ) To the control signal.

The control signal has a structure as shown in FIG. 6, for example. That is, it is composed of a bit synchronization signal and a frame synchronization signal for respectively establishing the synchronization of bits and frames, an ID number which is a number unique to the connection device (2), and a control code relating to call control.

In the connection device (2), first, the ID number included in this control signal is checked (S1). Next, the checked ID number is the self ID, that is, the connection device (2) own.
It is determined whether the ID numbers match (S2).

If the result of this judgment (S2) shows that they do not match,
The connection device (2) terminates its operation because it is considered that the control signal for reception is not the control signal for itself. On the contrary, if it is determined that they match, the process proceeds to the next step (S3).

In step (S3), an empty channel is designated by the control code included in the received control signal. As a result, the call channel related to the call between the slave station that issued the control signal and the connection device (2) is determined.

Next, the connection device (2) similarly makes a call using the control code to the slave station requested to be connected (S4). As a result, the communication channel between the connection device (2) and the slave station is determined.

Thus, for example, the slave station 1 (3) and the connection device 1
(2) By determining the communication channel between the connection device (2) and the slave station 2 (4) in steps (S3) and (S4),
Calls will be made between the slave stations (S5).

[Problems to be Solved by the Invention] However, in the conventional cordless telephone device, since the ID number is different for each connecting device, it is impossible to make a call between the slave stations under different connecting devices. That is, if the connecting devices are different, it is necessary to once make a call through the general subscriber telephone network.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a cordless telephone device capable of making a call between slave stations under different connection devices. To do.

[Means for Solving the Problems] In order to achieve such an object, a cordless telephone device of the present invention includes a plurality of connection devices and one or a plurality of connection devices provided for each of the connection devices. With a child station of
A slave station requesting a connection to another slave station then sends a control signal containing at least an individual ID number with a different number for each connecting device and a common ID number with a common number among a plurality of connecting devices in the same system. Send. Further, the connection device receives the control signal from the slave station, and if the individual ID number related to the reception matches the individual ID number of its own, the slave device corresponding to the own connection device is the transmission source of the control signal. Connect to the child station. Then, if the individual ID number related to reception does not match the individual ID number of own and the common ID number matches the common ID number of own, the individual ID number equal to the individual ID number related to reception is attached. A slave station corresponding to another connection device in the same system is connected to a slave station which is a transmission source of the control signal.

[Operation] In the cordless telephone device of the present invention, when a slave station under a certain connection device issues a control signal, the connection device performs a connection operation based on the individual ID number and the common ID number included in this control signal. To do. This connection operation is preferentially performed for the individual ID number. That is, when the connecting device determines that the individual ID number matches the own individual ID number, the slave station corresponding to this connecting device and the slave station of the control signal transmission source are connected. If the connection device determines that the individual ID number related to the transmission does not match its own individual ID number, the connection device makes a determination based on the common ID number. When the transmitted common ID number matches its own common ID number, the connecting device connects the slave station corresponding to the other one connecting device to the slave station of the control signal transmission source. As a result, it becomes possible to request a connection to a slave station corresponding to another connection device, and to make a direct call without going through the general subscriber telephone network.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.

The same components as those in the conventional example shown in FIGS. 4 to 6 are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 shows the configuration of a cordless telephone device according to an embodiment of the present invention. In this figure, slave station 1
(3) and the connection device 1 (2) related to the slave station 2 (4),
Connection device 2 (7) related to slave station 3 (8) and slave station 4 (9)
Is connected to the general subscriber telephone network (1).

The connection device 1 (2) and the connection device 2 (7) are each given a unique individual ID number. For example, when the slave station 1 (3) requests a connection with the slave station 2 (4), the slave station 1 (3) gives the connection device 1 (2) an individual ID indicating the connection device 1 (2). The number must be included in the control signal for transmission. Similarly, the slave station 3 (8) is connected to the connection device 2
When requesting (7) to connect to the slave station 4 (9), the slave station 3 (8) needs to transmit a control signal including an individual ID number indicating the connection device 2 (7).

Further, the connection device 1 (2) and the connection device 2 (7) are provided with a common ID number having a common value. This common
The ID number is a number according to the features of the present invention. That is,
It is shown that both the connection devices to which the same common ID number is assigned belong to the same cordless telephone system. For example, when the slave station 1 (3) requests the slave device 2 (7) to join the slave station 4 (9), the slave station 1 (3)
Includes a common ID number indicating that the connection device 1 (2) is a connection request within the same system, and an individual ID number indicating the connection device 2 (7) corresponding to the slave station 4 (9). Control signals also need to be sent.

FIG. 2 shows a flow of operations relating to inter-slave station connection in this embodiment.

In this embodiment, when the slave station transmits a control signal, the connecting device 1 (2) or the connecting device 2 (7) executes an ID number check (S6).

In this embodiment, the control signal has a structure as shown in FIG. 3, for example. That is, similar to the control signal of the conventional example shown in FIG. 6, a bit synchronization signal,
The frame sync signal and the control code are included,
Further, ID1 number and ID2 number are included as ID numbers. The ID1 number is a common ID number commonly given to the connection device 1 (2) and the connection device 2 (7) as described above, and the ID2 number is the connection device 1 (2) and the connection device 2
The individual ID numbers are given different values in (7).

In this embodiment, after the step (S6) is executed, first, the determination (S7) for the ID2 number is executed. In this determination (S7), it is determined whether the ID2 number of the connection device that received the control signal and the ID2 number of the control signal match. That is, it is determined whether or not the control signal transmitted from the slave station is for requesting connection with the slave station corresponding to the same connection device. In this determination (S7), if it is determined that they match, step (S8) is executed. This step (S8) has the same contents as steps (S3) to (S5) in the conventional example.

On the other hand, if it is determined in the determination (S7) that they do not match, the determination (S9) is executed. In this determination (S9), it is determined whether or not the ID1 number of the connection device that has received the control signal matches the ID1 number of the control signal. That is, it is determined whether or not the control signal from the slave station requests a call between the slave stations within the same system.

If it is determined in this determination (S9) that they do not match, the process in the connection device ends.

On the other hand, if it is determined that they match, the subsequent steps (S10), (S11) and (S12) are sequentially executed.

That is, if it is determined in the determination (S9) that the two match, the control device for receiving the control signal determines the call channel with the mobile station for transmitting the control signal (S10), and the mobile station to be connected. The call channel to and from is confirmed (S11), and as a result, a call is made between the slave stations (S12). The operations in these steps (S10) to (S12) are the same as the steps (S3) to (S5) in the conventional example.

As described above, in this embodiment, the control signal transmitted from the slave station includes the ID1 (common ID) number.
The (common ID) number is given to the connection device so that it has the same value in the same system. Therefore, if the slave station wants to talk to a slave station corresponding to another connection device,
The ID1 (common ID) number may be used as the connection device ID2 (individual ID) number corresponding to the requested slave station while maintaining the ID2 (individual ID) number. By doing so, it becomes possible to talk between the slave stations corresponding to different connection devices without using the general subscriber telephone network (1).

In this embodiment, for example, when the slave station 1 (3) requests a connection to the slave station 4 (9), the connection device 1
Although (2) shows an example in which this connection is in charge, the connection device 2
(7) may be in charge. Even in this case, the same effect can be obtained.

[Effect of the Invention] As described above, according to the present invention, a common common ID number is given to connection devices in the same system, and the common ID number is included in the control signal from the slave station. It is possible to make a call between the slave stations associated with different connection devices without going through the general subscriber telephone network.
