[0009]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. A public exchange 7 is connected to a base station 5 and a private electronic exchange 1. A mobile telephone 6 is connected via a base station 5, and an extension telephone 2, a maintenance terminal 3, and a database 4 are connected to the private branch exchange 1. The public exchange 7 performs a well-known authentication operation with the mobile phone 6. When an arithmetic expression for performing the same authentication operation as that of the authentication operation is input from the maintenance terminal 3, it is stored in the database 4. When a special number is entered from the extension telephone 2 and then a subscriber number of the mobile telephone 6 is entered, data corresponding to the subscriber number of the mobile telephone 6 and the extension telephone 2 is stored in the database 4. .

Next, the operation of this embodiment will be described with reference to FIGS. First, as shown in step 10 of FIG. 2, the operation formula of the authentication operation of the mobile phone 6 is registered in the database 4 from the maintenance terminal 3. This arithmetic expression is input as the same arithmetic expression as the one that is authenticated by the public exchange 7. In the case where the incoming call from the public exchange 7 to the mobile telephone 6 is set to be received by the extension telephone 2, in order to prevent the signal exchange between the public exchange 7 and the mobile telephone 6 from being performed thereafter, the process proceeds to step 11. Mobile phone 6 as shown
Is turned off so that communication with the base station 5 is disabled. Then, as shown in step 12, the extension telephone 2 dials, for example, a special number as a number indicating a location registration request, and then dials the subscriber number of the mobile telephone 6.

The private branch exchange 1 having received the dial signal analyzes the special number and recognizes that the request is a transfer request to the portable telephone, so as shown in step 13, the number of the extension telephone 2 and the portable telephone 6 The information corresponding to the subscriber number is registered in the database 4. Then, as shown in step 14, the subscriber number of the mobile phone 6 is set as one of the parameters in the signal for requesting the start of location registration, and the signal for requesting the location registration is transmitted to the public exchange 7. .

This signal is received by the public exchange 7 as shown in step 15. Thereby, the public exchange 7
Sets the authentication information of the mobile phone 6 as one of the parameters of the signal requesting the start of authentication, and transmits it to the private branch exchange 1 as shown in step 16. At this time, the same authentication information as that used in the public exchange 7 is transmitted. In addition, the public exchange 7 performs an authentication operation according to a preset operation expression as shown in step 17.

After transmitting the location registration request in step 14 and receiving the authentication request signal from the public exchange 7 in step 18, the private branch exchange 1 receives the authentication calculation signal from the database 4 as shown in step 19. Read the expression. Then, using the authentication information transmitted from the public exchange 7, the authentication operation is performed by the authentication operation expression as shown in step 20. The authentication result is Step 2
As shown in FIG. 1, it is transmitted to the public exchange 7.

The public exchange 7 receives the authentication result in step 22 and compares it with the authentication operation result calculated in step 17 in step 23. If they match, the mobile phone 6 is determined to have been successfully authenticated, and location registration information for transferring the incoming call to the mobile phone 6 to the private branch exchange 1 is stored as shown in step 24, and step 25 is performed. The end of the location registration is transmitted to the private branch exchange 1 as shown in FIG.

After transmitting the authentication operation result to the public exchange 7 in step 21, the private electronic exchange 1 receives a signal notifying the end of the location registration as shown in step 26, thereby notifying the end of the location registration. You can know.

On the other hand, as shown in step 30 of FIG.
If there is an incoming call to the mobile phone whose location has been successfully registered, the public exchange 7 sends an incoming signal in which the subscriber number of the mobile phone 6 is set on the premises based on the location registration information of the mobile phone 6 as shown in step 31. Since the private branch exchange 1 transmits the signal to the private branch exchange 1, the private branch exchange 1 receives the signal as shown in step 32.

Thereafter, the public exchange 7 transmits the authentication information to the private electronic exchange 1 in step 33, so that the public exchange 7 and the private electronic exchange 1 perform the same authentication as described above as shown in steps 33 to 40. Perform processing. If both are successfully authenticated, the public exchange 7 receives a response signal, that is, a notification of the authentication calculation result from the private electronic exchange 1, as shown in step 45, so that it can be known that the authentication has been successful.

Then, as shown in step 42, the private branch exchange 1 reads out information corresponding to the subscriber number of the mobile telephone from the database 4, and in step 43, replaces the subscriber number of the mobile telephone with the number of the extension telephone 2. Then, as shown in step 44, an incoming signal is transmitted to the extension telephone. As a result, the incoming call to the mobile phone arrives at the extension telephone registered in advance.

By transmitting predetermined information from the extension telephone to the public exchange 7 without performing an authentication operation,
It is conceivable that an incoming call to a mobile phone is made to reach its extension phone.However, since the public exchange is configured to perform the authentication calculation, it must be modified so as not to perform the authentication calculation. Switch 7 is special. Rather than having such a configuration, it is more economical to use the existing authentication calculation function as it is and to make a secure connection by performing the authentication calculation.

[0020]

As described above, the first aspect of the present invention is:
Authentication calculation of mobile phone performed in public exchange
It is performed at the private branch exchange, and the result of the authentication calculation is
To the public exchange, and the authentication result of the public exchange and the private branch exchange.
A match was detected. This allows mobile phones
Ensures public and private exchanges even when the power is off
To reduce the power consumption of mobile phones.
This has the effect of

[0021] The invention of claim 2 is in addition to the invention of claim 1.
The incoming call from the public exchange to the mobile phone
The call is transferred to the private branch exchange, and the transferred mobile phone
Incoming calls to the designated extension phone
Therefore, there is an effect that an incoming call to the mobile telephone can be transferred to the extension telephone while the function of the public exchange is kept as it is.
