Abstract

PURPOSE: A method for displaying and calling a phone number of a mobile terminal is provided to display and originate a phone number by discriminating when a user is connected to a wireless private network and when the user is connected to a public network, although the user inputs a partial number only of the phone number for searching the phone number. CONSTITUTION: When a function key and search numbers are inputted(402), a controller checks to determine whether a phone number including the inputted numbers exists in a phone book of an internal memory(404,406). If there is a phone number including the inputted numbers in the phone book, the controller determines whether a user is positioned in a private network service area(407). If the mobile terminal is within the private network service area, the controller adds a public network access character in front of the searched phone number and displays it on a display unit(408). When a user selects the phone number displayed on the display unit(410), the controller determines whether an origination key is selected for the corresponding phone number(412). When the user originates a call with the selected phone number, the controller originates a call to the phone number displayed on the display unit(414).

Description

How to Display and Call a Mobile Phone Number {METHOD FOR DISPLAYING AND CALLING TELEPHONE NUMBERS OF MOBILE COMMUNICATION TERMINAL}

The present invention relates to a mobile communication system, and more particularly, to a method for displaying and calling a telephone number of a mobile communication terminal in a mobile communication system capable of providing both public and private mobile communication services.

In general, a mobile communication network may be classified into a public mobile communication network and a private mobile communication network. Recently, a lot of researches have been conducted so that subscribers of mobile terminals registered in public mobile communication networks can receive private mobile communication services. That is, a system for registering a public network mobile communication terminal with a private mobile communication network to receive private network service has been developed so that a subscriber of the mobile terminal can be provided with a public mobile communication service and a private mobile communication service as a single mobile terminal. .

Accordingly, in a system capable of providing both public and private mobile communication services, the mobile communication terminal must dial the public network access letter first and make a phone call in the company's wireless private network when making a call to the public network in the private network.

On the other hand, when a user presses a phone number to make a call, the existing mobile communication terminal searches for a phone number stored in an internal phonebook if only a part of the outgoing phone number is entered, for example, only four numbers are entered. Mark it. Accordingly, the user of the mobile communication terminal selects one of the searched phone numbers so that the user can make a call without having to press the phone number.

1 is a flowchart illustrating a method of searching for a telephone number using only some numbers in a conventional mobile communication terminal.

Referring to FIG. 1, when the mobile communication terminal receives a search number in step 202, the mobile communication terminal proceeds to step 204 to search whether a phone number including the input number is in an internal phone book. The mobile communication terminal determines whether there is a searched phone number as a result of the search in step 206, and if the searched phone number is found as a result of the determination, the mobile communication terminal proceeds to step 208 and displays the searched one or more phone numbers on the display unit. Accordingly, the user can select one of the one or more telephone numbers displayed on the display unit. The mobile communication terminal selects the telephone number by the user in step 210 and proceeds to step 212 to check whether the user selects the calling key for the selected telephone number. The user may select and transmit one of the telephone numbers displayed on the display unit of the mobile communication terminal. If the user calls the selected phone number, the mobile communication terminal transmits the phone number selected in step 214 as the phone number displayed on the display unit.

However, when a mobile communication terminal provided with public and private mobile communication services is in a private network, the user of the mobile communication terminal searches only and selects a phone number stored in the phone book of the terminal by inputting only four digits of the outgoing telephone number. In the case of making a call, the mobile communication terminal transmits the call number stored in the phone book without using a public network access character. Therefore, the mobile communication terminal had to enter all the phone numbers to be sent together with the public network access character in order to transmit through the company's wireless private network.

Accordingly, an object of the present invention is to distinguish between when accessing a wireless private network and when accessing a public network even when a user searches a phone number by inputting only some numbers of outgoing phone numbers in a public and private mobile communication serviceable system. And it provides a phone number display and calling method of the mobile communication terminal to be able to call.

Each of the plurality of MSCs 2-1, .., 2-n may connect a plurality of BSCs (eg, 4-1, .., 4-m) connected to the PSTN / ISDN (Public Switch Telephone Network / Integrated). It controls access with other MSCs in the Services Digital Network) or public telecommunication network. Each of the plurality of BSCs 4-1, ..., 4-m performs radio link control and handoff functions, and each of the plurality of BTSs 6-1, ..., 6-k, 8-1,. .8-k), together with MSs 20, 22, and 24 belonging to its own communication service area, that is, its cell area, perform a function of configuring a wireless communication path and managing radio resources. In the HLR / VLR 10, the HLR performs a subscriber location registration function and a database function for storing subscriber information, and the VLR is in charge of a corresponding MSC among a plurality of MSCs 2-1, .., 2-n. It is a database that temporarily stores information of the MS existing in the cell area. If the MS moves to a cell area managed by another MSC, the information stored in the VLR is deleted. In the present specification, in order to distinguish the public / private shared cell area 14, the communication service area of BTSs 6-1, .. 6-6-k, 8-1, .. of the public mobile communication system is public. This is called a dedicated cell area. In FIG. 1, as an example, the communication service area of the BTS 8-1 among the BTSs 6-1,..., 6-k, 8-1,... ). Typically, the public dedicated cell area 15 is much wider than the public / private shared cell area 14 that is intended to benefit a particular group of communications services.
