Abstract

PURPOSE: A phone number storing method of a mobile communication switching system is provided to reduce a dangerous condition during driving and increase utilization of a mobile phone in a situation that a memo is not available by receiving a phone number of a called party through a send burst DTMF(dual tone multi frequency) message during a call communication and storing and originating the received phone call after termination of the call. CONSTITUTION: A caller dials a phone number by using a mobile phone, and depresses a transmission key to transmits the phone number to a mobile communication exchange(22). The mobile communication exchange requests an authentication of the caller from an authentication center, processes the call, and forms a speech path between the caller and a callee if the caller is in an idle state(24). The caller and the callee communicate through the speech path(26). The mobile phone determines whether a send burst DTMF message is received from the callee during communication(28). If the send burst DTMF message is received, the mobile phone extracts a phone number from the send burst DTMF message(30). The mobile phone determines whether a call is terminated(32). If the call is terminated, the mobile phone determines whether the extracted phone number is selected to be stored by a user when the call is terminated(34). If the user has selected to store the extracted phone number, the mobile phone stores the phone number for reading it anytime later(36). If the user has not selected to store the extracted phone number, the mobile phone determines whether the user has selected to originate the extracted phone number(38). If the user has elected to originated the extracted phone number, the mobile phone originates a call to the mobile communication exchange(40). The mobile communication exchange processes the call and arranges formation of a speech path between the mobile phone and a callee(42).

Description

How to store the phone number of the mobile switching system {METHOD FOR STORING A TELEPHONE NUMBER OF MOBILE COMMUNICATION EXCHANGE SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing a telephone number of a mobile communication switching system, and more particularly, to a method for receiving a telephone number of a counterpart during a telephone call, and then storing and calling the telephone number.

A user who makes a phone call using a mobile phone has many difficulties compared to a user who makes a phone call through a general phone. For example, a user who makes a phone call using a mobile phone is not only inconvenient but dangerous to take note of the phone number that the other party calls while driving. In addition, since the mobile phone user remembers the phone number that the other party announces and needs to remember the phone number until the end of the call in order to call later, the mobile phone user does not concentrate on a phone call with the other party.

Accordingly, the present invention has been made to solve the above-mentioned drawbacks of the prior art, and receives a telephone number of the other party through a send burst Dual Tone Multi Frequency message during a telephone call and then receives the call after the call is terminated. It is an object of the present invention to provide a method for storing a telephone number of a mobile communication switching system for storing and calling a telephone number.

A mobile communication switching system comprising a mobile telephone having a storage function, comprising: a first step of making a telephone call using the mobile telephone; A second step of determining whether a send burst DTMF message including a telephone number is provided from the other party; Extracting a telephone number from the send burst DTMF message when a send burst DTMF message is provided from the counterpart; A fourth step of determining whether or not the telephone call with the other party has ended; A fifth step of determining whether or not to store the extracted telephone number when the telephone call with the counterpart is terminated; A sixth step of storing the extracted telephone number if the extracted telephone number is selected for storage; A seventh step of determining whether or not the extracted telephone number has been selected for outgoing processing when the extracted telephone number has not been stored and selected; And if the extracted telephone number is selected for outgoing processing, an eighth step of calling using the extracted telephone number.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an embodiment of a mobile communication switching system for applying a phone number storage method of a mobile communication switching system according to the present invention, a mobile telephone (2), a base station (BS) (4), A base station controller (BSC) 6, a mobile communication exchange 8, an authentication center 10, and a home location register (HLR) 12.

In the figure, it will be described with reference to FIG.

Figure 2 is a flow chart showing step by step an embodiment of a phone number storage method of a mobile communication switching system according to the present invention.

First, the caller dials a predetermined telephone number using the mobile telephone 2 and presses the transmit key to transfer the dialed telephone number to the mobile communication switch 8 through the base station 4 and the base station controller 6. Send (step 22). The mobile phone 2 and the base station 4 are wirelessly connected, and the base station 4 and the base station controller 6 are wired.

The mobile communication exchange 8 requests the authentication center 10 to authenticate the caller and processes the call based on the call to form a call path between the caller and the called party when the called party is idle (step 24). The mobile communication switch 8 calls the called party through a preset network when the called party is in an idle state.

The caller and the called party make a call through the communication path formed by the mobile communication switch 8 (step 26). The home location register 12 provides location information and the like of a specific subscriber at the request of the mobile communication switch 8.

The mobile telephone 2 determines whether a send burst DTMF message containing a predetermined telephone number is received from the other party through the forward traffic channel during the call with the other party (step 28). When the other party transmits the send burst DTMF message including the phone number, the other party does not need to perform a separate mode setting process.

When the send burst DTMF message is received, the mobile phone 2 extracts the telephone number from the send burst DTMF message through a predetermined extraction unit (step 30).

The mobile telephone 2 determines whether the call with the other party has ended (step 32).

The mobile telephone 2 determines whether the user has selected to store the extracted telephone number when the call with the other party is terminated (step 34).

When the user selects to store the extracted telephone number, the mobile telephone 2 stores the telephone number in a predetermined storage device so that it can be read out at any time later (step 36).

On the other hand, the mobile telephone 2 determines whether the user has selected the origination of the extracted telephone number if the user has not selected to store the extracted telephone number (step 38).

The mobile telephone 2 transmits to the mobile communication exchange 8 through the base station 4 and the base station controller 6 when the user selects the origination of the extracted telephone number (step 40).

The mobile communication exchange 8 processes the call according to the origination of the mobile telephone 2 and arranges the formation of a call between the other party and the mobile telephone 2 (step 42).

As described above, according to the present invention, the telephone number of the other party is received through the send burst DTMF message during the telephone call, and the telephone number received after the call is terminated is stored and transmitted. Therefore, it is possible to reduce the risk of an accident while driving and to double the use of the mobile phone in a situation where other memos are difficult.
