A description will be given of a case where a call setting request is transmitted from the PS 43 to an extension number that does not exist in the extension number management table 41 of the CS 4. At this time, PS ・ 4
From 3, a call setting request is sent to CS 4 using a non-existent extension number as a telephone number.

The CS 4 is a telephone number determining means 4
According to 2, it is determined whether the input telephone number is an extension number or an external line number (a telephone number starting with 0 is determined as an external number, and a telephone number other than 0 is determined as an internal number). At this time, since the head of the telephone number is 0, the telephone number determination means 42 determines the telephone number of the call setting request as an extension number.

Then, since the telephone number determining means 42 has determined that the input telephone number is an extension number, it searches this extension number in the extension number management table 41 and finds the extension number in the extension number management table 41. It is determined whether or not to perform the operation (for example, the extension number management table 4).
It is determined that this extension number (extension PHS number) does not exist in No. 1. As a result, the CS 4 immediately transmits the call setup request to the CS controller 3 without transferring it to the CS controller 3.
3 is rejected and the communication is terminated.

Next, it is assumed that an extension number is transmitted from the PS 43 to the PS 53 existing in the extension number management table 41, for example. At this time, a call setting request is transmitted from the PS 43 to the CS 4 with the extension number of the PS 53.

The CS 4 determines whether the input telephone number of the call setting request is an extension number or an external line number by the telephone number determining means 42 (if the telephone number starts with 0, the external line number is used). Number, a case other than 0 is determined as an extension number). At this time, when the telephone number determining means 42 confirms that the head of the input telephone number is 0,
The input telephone number is determined as an extension number.

Then, the telephone number determining means 42
Since the telephone number input from 43 is determined as an extension number, the extension number is searched in the extension number management table 41 to determine whether or not this extension number exists in the extension number management table 41 (presence or absence). Do. As a result, the telephone number determination means 42, for example,
(S number) is present in the extension number management table 41.

Thus, the CS 4 transfers the call setting request from the PS 43 to the CS control device 3. And C
Since it is known that the PS 53 has been registered in the area of the CS 5, the S control device 3 sends a call setting request to the CS 5. As a result, PS
If a response is made to CS 5 in response to the call setting request, the connection between PS 43 and PS 53 is established by CS controller 3 via CS 4 and CS 5.

Finally, a case is described in which a call is made from the PS 43 to the PS 63 using an outside line number.
Call setting request transmission from PS3 / 63 using the outside line number is CS
-This is done for 4.

Then, CS · 4 is a telephone number determining means 4
According to 2, it is determined whether or not the telephone number from the PS 43 is an extension number or an external number (when the leading part of the telephone number is 0, it is determined as an external number, and when it is other than 0, it is determined as an internal number). . When confirming that the beginning of the input telephone number is a number other than 0, the telephone number determination means 42 determines the input telephone number as an outside line number.

As a result, the CS 4 determines that the input telephone number is an outside line number by the telephone number determining means 42,
The call setting request from the PS 43 is transferred to the CS control device 3 as it is. As a result, the CS control device 3
A call setting request from the PS 43 is sent to the CS 6 via the HS network 1, and if the PS 63 responds to the call setting request, the connection between the PS 43 and the PS 63 is established. .

As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. The present invention is also included in the present invention.
