Description

TECHNICAL FIELD The present invention relates to a method for connecting a communication path of a cordless telephone,
In particular, the present invention relates to the connection between the master unit and the slave units in a system having a master unit and slave units as one set and a plurality of sets.

[Prior Art] Conventionally, this type of cordless telephone has
In some cases, one slave unit is used and a plurality of slave units are installed and used.

Here, the one set of the master unit and the slave unit have independent ID codes different from the other sets, and this type of ID code is provided in all the sets.

When an incoming call is received by any of the parent devices, an ID code unique to the group is transmitted from the parent device, and a wireless line connection can be established with a child device that matches the ID code. It prevented interference with other groups.

[Problems to be Solved] In the above-mentioned conventional cordless telephone set, the ID code is determined for each set of the base unit and the handset unit. If you leave your seat without a handset and you receive an incoming call to that phone, you must go to the location of the child device to pick up the call, and you cannot effectively take the call. There was a problem.

Therefore, an object of the present invention is to solve the above-mentioned conventional problems and, when an incoming call is received by one set of telephones, without operating the one set of telephones, any other set of telephones is operated. Is to provide a method for connecting a call path of a cordless telephone capable of answering an incoming call on the telephone.

[Means for Solving Problems] According to the communication path connection method for a cordless telephone of the present invention, a master unit connected to a telephone line and a slave unit wirelessly connected to the master unit are set as one set, and a plurality of sets are provided. When connecting a call path to a cordless telephone set, it has an independent ID code for each group and an ID code common to each group. , An independent ID code is transmitted, a slave unit corresponding to the code is called, and if there is no response from the slave unit for a certain period of time, the common ID code is switched to be transmitted and all the slave units are called. .

[Embodiment] The present invention will be specifically described below with reference to an illustrated embodiment.

FIG. 1 is a schematic explanatory diagram of a cordless telephone system for carrying out the method of the present invention.

In the figure, this cordless telephone system is
o. 1-No. It is composed of 4 sets of cordless telephones up to 4.

Each group is provided with a master unit 2 connected to the telephone line 1 and a slave unit 3 wirelessly connected to the master unit 2.

In the present embodiment, an independent unique ID code is set for each set. That is, No. 1 set of unique I
D = 0001, No. 2 sets of unique ID = 0002, N
o. 3 unique ID = 0003, No. 3 4 sets of unique ID = 0004.

In addition, common ID =
0000 is set.

Further, each child device 3 has a unique sub ID code. That is, No. 1 set of sub ID = 1, No. Two
Sub-ID = 2, No. 3 sets of sub ID = 3, N
o. 4 sets of sub-ID = 4.

Next, an example of the method of the present invention using the apparatus of the above embodiment will be described below.

From the oscillation side (not shown), for example, No. The case where there is an incoming call to the master unit 2 of the first set will be described. A line is connected only to the slave unit 3 of one set, and a ringing tone is emitted to this slave unit 3.

Here, No. The owner of the telephone set of 1 is the slave unit 3
If the user leaves the seat without holding the key, the child device 3 cannot respond.

Therefore, in this embodiment, when the response is not received for a certain period of time,
A call is made to all the slaves 3 of the groups of the plurality of groups. In this case, some slaves 3 may respond, but the one that responds first is given priority and the slave 3 and the calling side are connected.

A specific explanation will be given below with reference to various IDs in FIG.
o. When there is an incoming call to the master device 2 of No. 1, first, this master device 2
Sends unique ID 0001, and No. An incoming call is made to the child device 3 of No. 1 and a ringing sound is given to the child device 3.

However, no. When the slave device 1 of 1 does not respond for several seconds, the call from the master device 2 is switched to the common ID 0000.

Then, an incoming call is made to all the slaves 3 in this group, and each slave 3 makes a ringing tone.

Here, No. If the child device 3 of 2 responds first,
This No. The second slave 3 transmits the sub ID 2 of the slave 3 together with the common ID 0000, and the sub ID 2 of the slave 3 is received by the calling side via the radio, the master 2, and the telephone line 1. Thereafter, the caller side returns a common ID 0000 + sub ID2, and the caller side and the No. The second slave unit 3 is wirelessly connected to the main unit 2 and the telephone line 1.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.

[Effects of the Invention] As described above, according to the present invention, when the slave unit does not respond for a certain period of time due to the transmission of the unique ID, all the slave units of a plurality of cordless telephone sets such as a system or a group can be called. Therefore, it is possible to use a plurality of sets of cordless telephones as one system, and even if the user leaves his / her seat without having the child device, any one of the telephones can surely respond.
