KR20040021894A - Caller ID Display Method in Mobile Communication System - Google Patents

Abstract

PURPOSE: A method for displaying a caller ID in a mobile communication system is provided to authorize a caller ID service subscriber to display his caller ID to a called terminal, even though the user of the called terminal hasn't joined the caller ID service. CONSTITUTION: If a caller ID service subscriber's mobile station(10) sends a location registration request to an MSC(40) through a BS(Base Station)(20) and a BSC(Base Station Controller)(30), the MSC(40) transmits a location registration message, including the subscriber's location registration information, to an HLR(Home Location Register)(50). The HLR(50) confirms the subscriber's authorization information and transmits a location registration notification response message to the MSC(40), including the subscriber's authorization information, extrinsic information, and caller ID service information. Afterwards, if the subscriber dials a destination number, the relevant signal is transferred to the MSC(40) through the BS(20) and the BSC(30). At this moment, the caller's number information is also transferred to the MSC(40), as well as the destination number. At this moment, the MSC(40) analyzes the caller's number as well as the destination number and judges whether a trigger for the caller's caller ID service is active. In case that the caller ID service is active, the MSC transmits an origination request message to the HLR(50). The HLR(50), receiving the origination request message, transmits a remote user interaction order message, containing an associated announcement code, to the MSC(40) in order to request the caller to input a number to be displayed at the destination mobile station.

Description

Caller ID Display Method in Mobile Communication System

The present invention relates to a caller ID display method in a mobile communication system, and in particular, when a subscriber makes a call in a mobile communication system, the caller is authorized to provide caller information to the called party even if the called party does not subscribe to the caller ID service. The present invention relates to a calling number display method in a communication system.

In general, a caller ID service by a caller in a mobile communication system is a service provided to a called party, and the caller's number to the mobile station (MSC) for the call received by the called party is sent to the called party. So that subscribers can make selective calls.

As shown in FIG. 1, a conventional mobile communication system for achieving a caller ID display service includes an originating mobile station 1, an originating base station 2, an originating base station controller 3, an originating mobile exchange 4, And a destination home location register (5), a destination mobile switch (6), a destination base station controller (7), a destination base station (8), and a destination mobile station (9).

The mobile stations 1 and 9 are communication terminals in which the mobile subscribers are provided with communication services, the base stations 2 and 8 are in charge of wireless communication with the subscriber mobile stations, and the base station controllers 3 and 7 control the base stations. And transfers the message of the exchange period with the corresponding base station, and the corresponding mobile exchange (4, 6) connects the call, classifies the exchange in which the caller is located to the calling mobile exchange and the exchange in which the called party is the destination mobile exchange, and the corresponding home. The location register 5 permanently stores information of a subscriber for providing a mobile communication service.

Caller ID display method in the conventional mobile communication system is described with reference to the scenario of FIG.

First, when a caller attempts to call a called party in a mobile communication system, the caller's information (hereinafter referred to as "caller number") is sent through the calling base station 2 and the calling base station controller 3, and the calling movement where the caller is located. Outgoing call operation to the exchange 4 is required. At this time, not only the called number dialed by the caller, but also the caller number indicating the caller is transmitted to the calling mobile switch 4.

The outgoing mobile switchboard 4 transmits the called party's location information request message to the called party's home location register 6 to establish a call to the called party's called party. At this time, the outgoing mobile switching center 4 transmits the called party number and the calling party number dialed by the caller to the called home location register 6. Receiving the corresponding location information request message, the destination home location register (6) searches the database of the called party with the dialed called number to obtain routing information necessary for call setup when the called party registers and activates the calling indication service. When transmitting the routing information request message to the destination mobile switch 7 in which the called party is located, the caller number received through the corresponding location information request message is included in the message.

The destination mobile switch 7 checks the current state of the called party and, if it is determined that the call can be set up, allocates a temporary routing number, stores the received caller number, and requests the routing home location register ( 6) transmits a routing information response message including the temporary routing number.

The destination home location register 6 which has received the temporary routing number from the destination mobile switch 7 transmits the location information request response message including the temporary routing number to the originating mobile switch 4 which has transmitted the location information request message.

Thereafter, the outgoing mobile exchange 4 attempts to set up the call with the destination mobile switch 7 with the corresponding temporary routing number, and the incoming mobile exchange 7 which has been requested to set up the call sends the calling party number to the destination mobile station 10. When sending an incoming call, the called party sees the calling number displayed on its mobile station and optionally accepts the call.

As described above, the caller ID display service is a service that displays the caller's number on the called party's mobile communication terminal when the call is transmitted by the mobile communication system. The conventional caller ID service provided by the mobile communication system allows the called party to selectively make a call by authorizing the called party to show the calling party's number.

However, the caller ID service provides a service to prevent the called party from receiving unwanted calls and to receive only the desired calls. However, in return for providing these rights to the called party, the caller's point of view is to provide his / her own information. Regardless of the will, personal information is infringed upon being viewed by the called party.

There is an advantage in that the called party can be selectively picked up so that the called party does not receive calls that he does not want to talk to, but rather the possibility of the caller's number being misused by the called party cannot be ignored.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned general problems, and an object thereof is to give a caller authority in a mobile communication system so that the caller's number is displayed to the caller even if the caller does not subscribe to the caller ID service.
