Abstract

Provides a method for restricting anonymous call reception in an asynchronous IMT-2000 network to prevent an incoming call when a caller attempts to include a caller ID indication restriction identifier.

In order to restrict anonymous call reception in asynchronous IMT-2000 network, called party should register calling number display service and anonymous call reception service. If caller ID restriction call is attempted to user of this additional service, After connecting to voice mail service center, send message to the caller and deliver the message to the called party.

The present invention implements such an anonymous call reception restriction service in the asynchronous IMT-2000 network, so that the service provided to the subscriber in the synchronous mobile communication system can be continuously provided to the subscriber of the asynchronous IMT-2000 network.

Description

Restriction of anonymous call reception in asynchronous IMT-2000 network {Method for Restriction of Anonymity Call in Asynchronous IMT-2000 Network}

The present invention relates to a method for providing an additional service in an asynchronous IMT-2000 network, and more particularly, when a caller attempts to include a caller ID indication restriction identifier or a caller ID service attempted call. The present invention relates to a method for restricting anonymous call reception in asynchronous IMT-2000 for preventing such an operation.

With the high penetration rate of wired and wireless terminals, subscribers can try to make calls with the desired party anytime and anywhere, and can conveniently use various services such as using voice services as well as data services such as wireless Internet using mobile terminals. It became.

Recently, in order to solve various problems (mischief, indecent, violent calls, etc.) due to the anonymity of the incoming call, the caller ID service has been provided. However, in response to the caller ID restriction service is implemented for subscribers who do not want their phone number known to the called party. Caller ID restriction service is registered with the mobile communication system whether to attempt to call with a specific identifier that indicates caller ID restriction when calling, or to restrict the caller ID display to its terminal. When the call is attempted to the terminal, there is a method of not displaying the calling number on the called party's terminal.

However, the called party using the calling number display service, when an anonymous call is received by the caller ID restriction, can not be sure of the identity of the caller, and thus refuses to receive the anonymous call. In the current synchronous mobile communication system, the service specification for the rejection of anonymous calls is defined, but in the asynchronous IMT-2000 network represented by the WCDMA system, there is no standard for providing such a service. have.

The present invention has been made to solve the above-described problems, and in the asynchronous IMT-2000 network, when a caller is a caller ID service user or attempts to call with a specific identifier for caller ID restriction, the caller calls the called party's terminal. There is a technical problem in providing an anonymous call reception service in an asynchronous IMT-2000 that does not connect.

In order to apply the anonymous call reception restriction service according to the present invention, the called party must register the calling number display service and the anonymous call reception restriction service. When a call number display restriction call is attempted to the user of the additional service, the asynchronous IMT-2000 network of the present invention delivers the message to the called party by ending the call without connecting the call to the called party or by inputting a message to the calling party. .

The called party can reject the anonymous call without any known procedure without any troublesome procedure. In case of an important call, the called party can receive the message inputted by the caller and confirm the condition. Furthermore, by allowing such a service to be provided in the asynchronous IMT-2000 network, the subscriber can receive the same service provided in the existing 2G network in the 3G asynchronous IMT-2000 network.

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

1 is a block diagram of an asynchronous IMT-2000 network according to the present invention.

As shown, the asynchronous IMT-2000 network (WCDMA system) is for controlling the Node B 20 and the Node B 20 as a base station for wireless section communication with the mobile communication terminals 10-1 to 10-n. Connected to a Radio Network Controller (RNC) 30, one or more Radio Network Controllers 30, a Mobile Switching Center (MSC, 40) for call exchange, management of subscriber information and availability of additional services, etc. Home Location Register (HLR) 50, an intelligent network service control point (SCP) 60 that stores and manages control information and subscriber data for intelligent network services, and a wireless network controller 30 and an IP network. Data service node (SGSN, 70) for monitoring the location of mobile communication terminals 10-1 to 10-n, and performing security and access control functions. Access to SGSN 70 over packet domain PLMN backbone Is a data service gateway node (GGSN, 80), a customer-oriented information system designed, built, and operated in a mobile communication system. It is a comprehensive customer information center that manages customer management, billing, billing, and payment. Oriented Information System (COIS, 90), is connected between the exchange 40 and the home location register 50, the exchange 40 receives the voice message from the calling subscriber as the call setup request message stored and stored, Voice message service center (VMS) 100 for transmitting the message to the called party.

Referring to the voice message service center 100 applied to the present invention in more detail, when the called party is a calling number display service user and has applied for an anonymous call reception restriction service, the calling number display restriction service user calls the called party. Or when the originator attempts to originate with a specific identifier for limiting the origination number indication, the call from the originating exchange 40 by the routing number sent by the home location register 50 to the originating exchange 40. Receives a setting request message and receives and stores a voice message from the caller. In addition, the voice message input by the caller is delivered to the called party so that the called party can check and cope with the voice message.

In addition, the home location register 50 of the present invention, if the mobile communication service subscriber requests registration of various additional services (calling number display service, anonymous call reception restriction service, etc.) through the COIS 90, the subscriber's information field is entered in the information field of the subscriber. Register whether to activate the supplementary service. In addition, when the caller attempts to call the caller ID restriction state, the called party is notified to the calling exchange that the caller is an anonymous call reception restriction service, and when the calling party transmits the announcement code, the calling exchange is sent to the calling terminal. Broadcast announcements.

2 is a flowchart illustrating a method for restricting anonymous call reception in an asynchronous IMT-2000 network according to the present invention. In order to apply the present invention, the called terminal user must register the calling number display service and the anonymous call rejection service.

First, when the call is attempted together with the calling number and the called number from the calling subscriber terminal (MS _O ) (S101), the calling side exchange (MSC _O ) checks the calling party information and then requests the called party information to the home location register (MAP_SRI). MAP Send Sending Information (S102). That is, the MAP message used in the asynchronous IMT-2000 network includes the information indicating that the caller requests the restriction of the calling party number in the message (MAP_SRI) requesting the destination side path information and transmits it to the home location register. At this time, the caller enters a specific identifier (for example, * 23 #) together with the calling number to limit the calling number display, and attempts to make a call, or before calling the home address to the home location register through the COIS (90). You can register caller ID restriction service. In addition, when the calling side exchange (MSC _O ) requests the called party information to the home location register, the calling side exchange (MSC _O ) transmits the calling number, the called number, and the additional service usage status of the caller (that is, calling number = display restriction state).

The home location register confirms that the caller is restricted from displaying the calling number by the message (MAP_SRI) received from the calling exchange (MSC _O ), while referring to the called number, the called party's additional service setting status, that is, displaying the calling number. Check whether to use the anonymous call reception service at the same time as the service (S103).

The home location register which checks the additional service setting status of the called party performs the general call processing process when the called party is not the calling party number service and the anonymous call reception restriction service user, and the called party uses the calling number display service and the anonymous call reception restriction service user. In case of, it notifies the originating exchange (MSC _O ) of the reception restriction fact, and at this time, the home location register may transmit the announcement broadcast code to the originating exchange (MSC _O ) together (S104). Here, the announcement code means a code of announcement for notifying the reception restriction fact among announcements stored in the MSC _O. In addition, when the called subscriber is a voice message service user, the home location register transmits a reception restriction fact and announcement code to the calling side exchange (MSCO), and sends a routing number for transferring the call to the voice message service center 100. Send together.

Reception restriction In fact, the MSC _O receiving the announcement code and routing number sends a announcement to the originating terminal MS _O to inform the reception that the reception has been rejected, and then releases the call. (S105).

It is not a method of transmission by a guide broadcast code in the response signal for the call information request signal (MAP_SRI) defined in the current caller-side switching center (MSC _O) in an asynchronous IMT-2000 network by, but, to the destination information request, in the present invention Information received by the calling exchange (MSC _O ) to the calling terminal (MS _O ) by transmitting to the calling exchange (MSC _O ) by including a specific parameter (for example, SKTInformationToSend) for transmitting the announcement code in the response signal to the calling terminal (MS _O ) The announcement broadcast corresponding to the broadcast code can be transmitted.

In a preferred embodiment of the present invention, the MSC _O may transmit a call setup request message to a voice message service center by referring to a routing number received from a home location register after transmitting an announcement before releasing a call. There is (S106). Voice message service center, and be prompted to enter the voice message to the originating terminal (MS _O) in accordance with the call set-up request from the caller-side switching center (MSC _O), Accordingly, when the caller inputs a voice message (S107), this called party Transmitting to the switching center (MSC _T ) (S108) and the receiving side switching center (MSC _T ) transmits a voice message to the called terminal with reference to the called number (S109).

As such, when the caller inputs a voice message, the called party can check the caller's condition even if the caller refuses to receive the call. In other words, when an anonymous call is received, the caller can unnecessarily reject the call and check the service afterwards. The caller can forward the call without exposing his / her phone number to the caller.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, the present invention enables an anonymous call reception restriction service in an asynchronous IMT-2000 network. The anonymous call reception limit service does not receive an anonymous call to a subscriber using the caller ID display service and the anonymous call reception limit service, thereby limiting the anonymous call without the recipient knowing it. In addition, when an anonymous call is restricted, the calling subscriber can input a message to the called subscriber without exposing his / her phone number.
