Abstract

A method for providing a service of refusing to receive an anonymous call in a mobile communication system is provided to enable a user, who has subscribed for an anonymous call receipt refusal service, to receive an international call by temporarily releasing the anonymous call receipt refusal service in case of receiving an international call whose sending side can be clearly discriminated. A method for providing a service of refusing to receive an anonymous call in a mobile communication system comprises the following several steps. MSCs(Mobile Switching Centers) connected to base stations receive a call connection request(S1). A receipt side MSC which has checked a subscriber profile from an HLR(Home Location Register) checks a phone number of a call sending side terminal when an anonymous call receipt refusal service is performed(S2). If the receipt side MSC determines that a sending number can not be checked(S3), the receipt side MSC checks a signal point of the sending side terminal(S4). If the sending number can be checked, the receipt side MSC transmits a sending number to a receipt side terminal(S5) and makes the receipt side terminal receive the call(S7). If the signal point of the sending side terminal is an international call whose sending side can be discriminated(S6), the receipt side MSC releases the anonymous call receipt refusal service and normally connects the sending side terminal to the receipt side terminal(S7). If not, the receipt side MSC stops a call connection via the anonymous call receipt refusal service(S8).

The present invention relates to an anonymous call rejection service method in a mobile communication system, and more particularly, to an anonymous call rejection service that rejects a call request when a caller number is not verified when providing a caller identification service in a wireless communication service system. In the method, when the caller can clearly distinguish the calling party, the present invention relates to an anonymous call rejection service method in a wireless communication system which temporarily releases an anonymous call rejection service so that a normal call is received.

As computers, electronics, and communication technologies evolve rapidly, various wireless communication services using wireless networks have been provided.

The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which provides a voice call service regardless of time and place.

In addition, recently, a wireless Internet service for providing an Internet communication service to a user of a mobile communication terminal through a wireless communication network is provided.

Accordingly, the subscribers of the mobile communication service can freely move and talk with the other party anytime and anywhere by using the wireless communication service, and various information necessary for life through the wireless Internet service, for example, news, weather, sports, securities, and exchange rates. Alternatively, the traffic information may be provided in various forms such as text, voice, or image.

On the other hand, current mobile communication service providers are providing a caller identification service that displays the caller's number to the terminal of the receiver when a call request is received.

This caller identification service is limited in terms of privacy, and additionally, the caller protection service is added to prevent the caller's number from being sent when the caller wishes.

However, when the caller protection service is performed at the same time as the caller verification service, the caller ID may not be known when there are many recipients, and thus the meaning of the caller identification service is weakened.

Accordingly, in the related art, an anonymous call rejection service is provided to prevent the fading of the purpose of implementing the caller identification service while simultaneously performing the caller identification service and the caller protection service.

This anonymous call rejection service is a service that allows a recipient to specify a call rejection for a call that the caller has specified caller ID restriction. For example, a caller restricts the caller ID to a customer who is using an anonymous call rejection service. If you are calling, "The other party is refusing to receive a call that does not have a number. Please remove the restriction and call back." It provides the announcement.

However, since the conventional anonymous call rejection service is applied collectively to all local calls, local calls, and international calls, a method of temporarily releasing only a specific calling party (eg, an international call) may be used. There was no.

Therefore, in the conventional anonymous call rejection service method, the subscriber often wants to be called when the international call is made. However, since there is no service system that can support this, even if the caller is an international caller that can clearly distinguish the calling party, There was a problem of rejecting the incoming call.

The present invention was made to solve the problems of the prior art, in the anonymous call reception service method for rejecting a call request when the caller ID is not confirmed when providing a caller identification service in a wireless communication service system; In the case of an outgoing call that can clearly distinguish the calling party, the wireless call system provides an anonymous call rejection service method to temporarily release the anonymous call rejection service.

The present invention for achieving the above object is an anonymous call reception denial service method for rejecting an incoming call when the caller's caller ID is not confirmed in the wireless communication service system, the caller signaling point when the caller ID is not confirmed For a specific signal point that can identify the calling party by checking the temporary call to the anonymous call rejection service to receive a normal call; further comprises.

In the present invention, the anonymous call rejection service temporary release is characterized in that when the calling party signaling point is a GLR (Gateway Location Resistor), the anonymous call rejection service is temporarily determined by determining that the calling party is a specific calling party signal point that can distinguish the calling party. It is done.

Herein, the specific calling party signaling point is an international calling signal.

As described above, in the anonymous call rejection service method, when the caller can clearly distinguish the calling party, the anonymous call rejection service subscriber can receive an international call by temporarily releasing the anonymous call rejection service temporarily. Customer satisfaction.

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

1 is a block diagram illustrating an anonymous call reception service method in a mobile communication system according to the present invention, and FIG. 2 is a flowchart illustrating an anonymous call reception service method in a mobile communication system according to the present invention.

First, as shown in FIG. 1, the wireless communication system performs a base station 20 for exchanging information with the mobile communication terminals 10 and 11 through a transmission / reception antenna, wired / wireless channel management terminal protocol matching, and base station protocol matching and control. A base station controller which performs base station management functions such as system loading failure management, and a central control function that processes signals transmitted and received at the base station and adjusts the base station controller so that the base station controller can be efficiently operated. (MSC: Mobile Switching Center) and the home location register (HLR) 40 for informing the subscriber location and various information such as the subscriber's origination, incoming status, and additional services.

The HLR 40 stores information about the assigned subscriber mobile terminals 10, 11, including location information and service information, in its database (not shown). In addition, the database of the HLR 40 stores information on whether to subscribe to the caller identification service of each of the mobile terminals 10 and 11 in the service subscription information file according to the present invention.

The exchange 30 31 interfaces a user call from a wireless network to a wired network or other wireless networks. The exchange 30 is connected to a plurality of base stations 20 and connected to other communication networks, for example, when receiving a call request from a PSTN, the subscriber profile of the HLR 40 determines whether the called party is a caller identification service subscriber. Check through.

At this time, when the call requesting subscriber is a caller identification service subscriber, the switch 30 and 31 confirm the existence of a caller ID identification presentation (CNIP) of the caller. In addition, when the call requesting subscriber is an anonymous call rejection service subscriber, the caller rejects the incoming call for the specified caller ID restriction.

As shown in FIG. 2, the present invention provides an anonymous call reception rejection service method for rejecting an incoming call when a caller's caller ID is not confirmed in a wireless communication service system. For the specific calling party signaling point that can identify the calling party, the anonymous call rejection service is temporarily released to make a normal call.

First, when the exchanges 30 and 31 connected to the plurality of base stations 20 receive the call request (S1), it is determined whether the subscriber who received the call is the caller verification service subscriber or the anonymous call rejection service subscriber of the HLR 40. Check through the subscriber profile.

The caller identification service or anonymous call reception service is performed according to the subscriber's subscription information.

In particular, when the anonymous call reception service is performed, the called party exchanger 31, which checks the subscriber's profile from the HLR 40, checks the calling party's phone number (S2) and determines that the calling number cannot be verified (S3). The method may further include checking a side signal point (S4).

Of course, when the calling number is confirmed, the calling party transmits the calling number to the called terminal 11 (S5) and receives the call (S7).

The originating signal point check (S4) determines that a specific originating signal point that can distinguish the originating party when the signal coming into the exchange 31 is a Global System for Mobile Communication (GSM_GLR) or Code Division Multiple Access (CDMA_GLR). .

When a specific calling party signaling point capable of distinguishing the calling party, that is, the calling party is an international caller (S6), even if the called party is an anonymous call rejection service subscriber, the temporary call rejection service is temporarily released. The terminal and the called terminal are called normally (S7).

Of course, even if the calling party cannot check the calling number and is not an international outgoing call, the call connection is normally stopped through the anonymous call reception service (S8).

In other words, the anonymous call reception service determines whether the call is anonymous at the step of requesting the location information of the called party from the calling exchange in the HLR, and if the anonymous call is an anonymous call, the call including the access denied reason (Access Denied Reason). Pass it to stop.

The present invention checks the originating signal point at the step of determining whether an anonymous call is made in the HLR, so that the GSM_GLR and CDMA_GLR receive the normal call without performing the anonymous call verification. Allows you to perform a function.

As described above, in the anonymous call rejection service method, when the international caller can clearly distinguish the calling party, the anonymous call rejection service subscriber can receive an international call by temporarily releasing the anonymous call rejection service. Make sure

As described above, in the anonymous call rejection service method, in the case of an international outgoing call which can clearly distinguish the calling party, the anonymous call rejection service subscriber makes an international call by temporarily releasing the anonymous call rejection service. There is an advantage of realizing customer satisfaction by allowing them to receive.
