Description

Description: TECHNICAL FIELD The present invention relates to a wireless telephone device, and more particularly, to registration of an identification code for collation at the time of wireless connection between a parent device and a wireless telephone.

[Conventional technology]

As a wireless telephone device of this type, there is a cordless telephone device. In this cordless telephone device, when the parent device and the wireless telephone are connected to each other by a wireless line, an identification code is stored in a storage means provided in each to prevent erroneous connection. The identification code was collated.

[Problems to be solved by the invention]

In the above-mentioned conventional cordless telephone device, the content of the identification code is written and fixed at the time of manufacture and cannot be rewritten. On the other hand, there is also one in which the user can arbitrarily set the identification code by using a DIP switch or the like. However, the number of digits of this is not sufficient and there is a risk that the identification code will be the same as other wireless telephones.

When a plurality of wireless telephones are connected to one parent device for use as in a wired parent-child telephone device and a key telephone device, an identification code that matches the identification code of the parent device is attached to each wireless telephone. Need to be remembered. In this case, if the identification code is written and fixed during manufacturing,
When adding a wireless telephone later, there is a drawback that it becomes impossible because the identification codes do not match.
In order to eliminate this drawback, it is necessary to prepare a storage means for storing the identification code of the parent device each time or to equip the parent device in advance.

In addition to the above, there is also a method in which the wireless telephone to be newly added can store the same identification code as the identification code of the parent device, but in this case, the identification code of the parent device is known to others. Therefore, there is a risk of so-called "free-for-all" being stored in the new wireless telephone.

[Means for solving problems]

The wireless telephone device of the present invention is, in the parent device, a telephone circuit, a wireless transceiver, a storage unit for storing a first identification code, and a first wireless telephone from the first wireless telephone. If a second identification code of a wireless telephone other than the above and an identification code registration request signal including the extension number to be registered are received, the wireless telephone storing the second identification code is called and the first identification is performed. The wireless telephone has a control unit for controlling to transmit an identification code registration signal including a code, and in addition to the handset and the wireless transceiver, the first and second wireless telephones.
When the identification code registration signal is received from the parent device, the first identification code is stored as a rewritable storage means for storing the identification code of It has a control unit which stores it in the storage means and thereafter performs collation using the stored first identification code when making a call to, receiving a call from, and making a call to the parent device.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The parent device 1 accommodates the telephone line 101 in the telephone circuit 11 and sends an audio signal 102 to the wireless transceiver 12. The parent device 1 also receives an audio signal 103 from the wireless transceiver 12. As is well known, the telephone circuit 11 includes an incoming call detection circuit, a dial circuit, and a two-wire / four-wire conversion circuit, and is controlled via a telephone circuit control line 104 from the control unit 13. The wireless transceiver 12 is the wireless transceiver control line 10
The control unit 13 controls the transmission / reception on / off and channel switching via 5. In FIG. 1, the parent device 1
Has one telephone circuit and one wireless transceiver, but it may have more than one if necessary. Further, the control unit 13 is connected to an identification code memory 14 formed of a ROM that stores a first identification code having a function as an ID number, and collates the contents with the identification code from each wireless telephone at the time of sending and receiving, If it does not match, it will not be accepted.

In the wireless telephone 2, the wireless transceiver 22 controlled by the telephone controller 23 via the wireless transceiver control line 203.
And a wireless transmitter / receiver 22 which is connected to the wireless transceiver 22 via a reception signal line 201 and a transmission signal line 202. The telephone control unit 23 stores a rewritable identification code memory 24 by EEPROM for storing a first identification code as an ID number common to each telephone and a second identification code different for each telephone. The ROM is connected to the identification code memory 26 and the data input unit 25 which is an input means such as a dial.

Although the identification code memory 24 and the identification code memory 26 are shown separately in FIG. 1 for the sake of description, they may be stored at different addresses on the same memory and can be distinguished from each other.

The wireless telephone 3 and subsequent elements have the same configuration as the wireless telephone 2.

Next, the procedure for registering the identification code will be described.

FIG. 2 is a sequence chart showing the procedure for registering the identification code. Here, the wireless telephone 2 is first the parent device 1
The first identification code that matches the first identification code of the parent device 1 is stored in advance as the first identification code.

The wireless telephone 3 is a wireless telephone to be registered and will be added later, so the first identification code does not match the first identification code of the parent device.

In addition, the second identification code of the wireless telephone 3 is input from the wireless telephone 2. This second identification code is made to correspond to, for example, the manufacturing number given to each radio telephone, and the radio telephone 3
It is stored in the identification code memory 26 at the time of manufacturing (S101). Next, the registration request signal including the first identification code of the wireless telephone 2 and the input second identification code is transmitted from the wireless telephone 2 to the parent device 1 (S102). When the parent device 1 receives the registration request signal, it checks whether or not the first identification code therein matches the first identification code of the parent device 1. Then, if they match, the parent device 1 calls the wireless telephone having the same second identification code as the second identification code in the registration request signal, that is, the wireless telephone 3 (S).
103).

The wireless telephone 3 confirms whether the second identification code of the call from the parent device 1 matches the second identification code of the wireless telephone 3 (S104), and if they match, returns a response to the parent device 1. (S105). Next, the parent device 1 is the first
The registration signal including the identification code is transmitted (S106), and the wireless telephone 3 stores the first identification code in the identification code memory 24 (S107). After that, when the wireless telephone 3 makes and receives a call, a signal with the first identification code is transmitted to perform verification.

Before the above-described registration, since the first identification code of the wireless telephone 3 does not match that of the parent device 1, it is not possible to connect the parent device 1 to the wireless line to make outgoing and incoming calls. .

〔The invention's effect〕

As described above, according to the present invention, the wireless telephone is provided with a rewritable means for storing the first identification code and the second identification code, and the activation is performed from the wireless telephone in which the first identification code matches the parent device. Thus, by rewriting the first identification code of the wireless telephone to be newly added via the wireless line so as to match the first identification code, the wireless telephone can be easily added. As a result, it is not necessary to prepare a storage means for storing the first identification code of the parent device each time it is added and replace or additionally mount it. There is an effect that it is not necessary to have the storage means.

In addition, since the same first identification code as that of the parent device cannot be stored only by the wireless telephone to be newly added, there is an effect that there is no risk of being so-called “free-lance” by another person's wireless telephone. .
