Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and more particularly to a system for reducing dial operation in a mobile telephone terminal.

[0002]

2. Description of the Related Art Conventionally, a mobile telephone terminal has designated a called number by dialing with a maximum of 10 digits and a minimum of 9 digits when entering a general telephone network.

[0003]

As described above, the conventional mobile telephone terminal always requires a dial operation of 9 digits or more when entering the general telephone network, and the same operation is required from a mobile terminal located in a certain city. Even when making a call to a general telephone network terminal in a city, the number was dialed from the area code.

For this reason, erroneous dialing such as an incorrect area code has occurred.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, the object of the present invention is to make a dial from the area code to call anywhere in the mobile terminal. In a mobile phone terminal that can be solved by dialing from the local number only when calling to the nearest city, preventing the user from dialing incorrectly, and solving the above problems inherent in the conventional technology. It is to provide a new dial operation reduction system.

[0006]

In order to achieve the above object, a dial operation mitigation system for a mobile telephone terminal according to the present invention is applied to a mobile telephone terminal, a radio base station and an exchange which constitute a mobile communication network. It is characterized by having the following functions.

Mobile telephone terminal: A function that indicates to which city from the place where the own terminal is connected by an area code. Radio base station: A local area telephone that indicates which city the own station is connected to. Function to notify mobile phone terminals in number units Telephone exchange: Identify whether or not the call from the terminal is a local call, and when making a local call, add the area code specific to the wireless base station. Function to give and carry on general fixed net access

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings with reference to its preferred embodiments.

FIG. 1 is a block diagram showing an embodiment of the present invention. 11 is a wireless base station, 12 is a wireless base station 11
A mobile telephone terminal wirelessly connected with and a telephone exchange 13 accommodating the radio base station 11, respectively.

The radio base station 11 continuously or periodically transmits the area code of the city to which it is connected, which is designated by the exchange 13, to the mobile telephone terminal 12 through a radio control channel.

The mobile telephone terminal 12 displays the area code received from the radio base station 11, and the user performs the calling operation while referring to this area code, but the mobile telephone terminal 12 uses this area code. The dialed number according to the calling operation is transmitted to the wireless base station 11 according to the operation.

The radio base station 11 which has learned the call from the mobile telephone terminal 12 also transmits the call from the mobile telephone terminal 12 to the telephone exchange 13 while keeping the dialed numbers as they are.
Determines the first dialed number among the dialed numbers of this call according to the flowchart shown in FIG. 2, that is, when the first number is any number from "2" to "9". It is determined that the call is a local call, and when the call is a local call, a unique area code is added to the radio base station 11 before the dialed number to enter the general fixed-line telephone network.

The telephone exchange 13 also performs the conventional exchange operation when the first digit is "0" or "1".

[0013]

As described above, according to the present invention,
When making a call from a mobile telephone terminal, the area code is automatically added on the side of the telephone exchange by the passing wireless base station, so dial operation with a minimum of 2 digits and a maximum of 6 digits can be eliminated. The effect is obtained.
