Abstract

A system and method for providing a reception limit service in a mobile communication network are provided to remove a problem that a callee must check an origination number whenever a bell rings to receive a call and that the callee rejects an incoming call whenever an undesired caller keeps calling maliciously. A CSS(Call Screening Server)(116) registers/stores information on mobile terminals in a mobile communication network registered for a reception limit service, and provides reception limit information of an origination terminal when searching of an origination terminal which has been set for the reception limit is requested. When an HLR(Home Location Register)(120) receives a phone number of an origination terminal, it checks whether the origination terminal has been set for the reception limit, and provides result information together with position information. A sound source transmission server(114) transmits a message informing the reception limit-set origination terminal that destination to a destination-requested terminal is not possible, through an MSC(Mobile Switching Center)(112). The MSC(112) transmits the number of the origination terminal to the HLR(120) to check whether the origination terminal is a reception-limited terminal, and if so, the MSC(112) transmits a destination unavailable message stored in the sound source transmission server to the origination terminal(114).

Description

Restriction service system and method in mobile communication network {SYSTEM FOR RESTRICTING CALLS FROM CALLER IN MOBILE COMMUNICATION SYSTEM AND METHOD THEREOF}

TECHNICAL FIELD The present invention relates to a mobile communication system, and more particularly, to a reception restriction service system and method for restricting reception of a specific caller number in a mobile communication network.

In general, a reception restriction service in a mobile communication terminal refers to a service that allows a mobile communication terminal user to restrict reception of an unwanted call from an external caller. Conventionally, when a called party is subscribed to a PCA, a specified password is input. External caller that the user of the device does not want through the PCA service, which allows the caller to call only if the password is correct, and the pre-receipt service that allows the caller to enter a phone number, confirm the caller in advance, and optionally make a call. It has been supported to restrict incoming calls.

However, in the PCA service, all callers except the unwanted caller should be notified of their passwords, and callers who want to make calls must enter their passwords each time, and passwords can be easily leaked, effectively preventing reception from unwanted callers. There was a problem that could not be done.

In addition, in the pre-receipt confirmation service, if the caller's phone rings, the caller has to make a call after checking the caller's number every time. There was a ham.

Therefore, the object of the present invention is to implement the call screen by registering the calling number to the server in the mobile communication only, so that the caller's phone does not ring, and do not need to notify the caller of the password to the caller's position It is an object of the present invention to provide a system and a method for restricting reception in a mobile communication network that can conveniently and safely receive a call.

The present invention for achieving the above object, a specific number reception restriction system and method in a mobile communication network, registers and stores the information of the mobile communication terminals in the mobile communication network registered in the reception restriction service, and retrieves the information on the calling terminal set the reception restriction CSS for providing reception restriction information of a corresponding calling terminal requested to be searched upon request; An HLR that checks the reception restriction information of the calling terminal through the CSS and provides the location information together with the location information when receiving the telephone number of the calling terminal requesting the calling through the mobile communication network; A sound source sending server configured to send a message indicating that the incoming call to the called party which has been set to the reception restriction cannot be received through an MSC; MSC for transmitting a caller terminal number to the HLR when the caller requests from the caller terminal to check whether the caller is limited to the receiving terminal, and transmits the unreachable message stored in the sound source server to the caller. Implementing a reception restriction service system, and (a) transmitting the calling number of the calling terminal to the HLR when the call request of the calling terminal through the mobile communication network; (b) checking whether the originating number is a registered originating terminal restricted to the incoming called terminal by applying the received originating number to CSS; (c) transmitting the registration restriction information and the registered location information of the calling terminal checked from the CSS to an MSC; (d) transmitting a non-receiving message to a corresponding called terminal set in advance according to the reception restriction registration of the calling terminal to limit the incoming call to the called terminal; .

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

1 is a block diagram of a mobile communication system capable of a call screen service according to an exemplary embodiment of the present invention. Referring to Figure 1 below,

Mobile stations (MSs) 100 and 106 are user interface devices, and establish a wireless transmit / receive channel with a counterpart mobile communication terminal through a mobile communication network to enable voice and data transmission / reception between terminal users.

Base Transceiver Station (BTS) 102,108 is a device configured as a wireless transceiver, and transmits / receives voice calls, SMS messages, MMS messages, etc. via a wireless link with the mobile communication terminals 100,106. The base station controllers (BSCs) 104 and 110 manage a plurality of BTSs 102 and 108 and are responsible for radio channel setup, frequency hopping, and handover processing.

The Mobile Switching Center (MSC) 112 is responsible for mobility management, location registration / management, authentication, handover, roaming, etc. of the mobile communication terminals 100 and 112. In addition, when receiving an incoming request from the mobile communication terminal (100, 106) through the base station (BTS) (102, 108), an outgoing signal is transmitted to the called party of the incoming request, and there is a response from the other party's terminal to the incoming signal. In this case, channels are allocated to form communication paths between the mobile communication terminals 100 and 106.

Meanwhile, the MSC 112 transmits the changed location registration information of the terminals to a home location register (HLR) 120 that manages location registration information of the corresponding terminal implemented in the No. 7 network 118. The location information of the communication terminal is periodically updated, and in response to an incoming call from a calling terminal registered with a call screen service with a reception restriction according to the present invention to a called terminal registered with the call screen service, a sound source transmission server ( 114) the pre-stored incoming impossible message is received and transmitted to the corresponding calling terminal to inform that the incoming call is impossible.

When the HLR 120 receives the telephone number of the calling terminal requesting the call from the MSC 112 through the mobile communication network, the calling terminal phone number is transmitted to the Call Screening Server (CSS) 116 connected through the IP network 122. Request to check whether the calling terminal is a calling terminal registered as a receiving limit terminal of a called terminal subscribed to the call screen service, and whether to register a receiving limit for the calling terminal from the CSS 116. Information is received and provided to the MSC 112 together with the location information of the calling terminal.

CSS 116 stores the information of the mobile communication terminals registered in the reception restriction of each incoming terminal subscribed to the call screen service, and when the request to check the reception restriction setting for the calling terminal from the HLR 120, It checks the reception restriction state of the calling terminal and provides the reception restriction registration information to the HLR 120.

In this case, when the user wants to register for a call screen service, the user sets a list of calling terminal numbers to be restricted in the CSS 116, and sets a call processing method to handle the incoming call when the incoming call is received from the restricted calling terminal. The CSS 116 also provides call processing method information registered by the user when providing the reception restriction status registration information of the calling terminal to the HLR 120, so that the MSC 112 processes the registered call. Depending on the method, the incoming call can be handled.

In the call processing method, a user sends a message to a corresponding destination terminal such as, for example, a default guidance message transmission, VMS switching, automatic call termination, music transmission, transmission of a message recorded by him, and transmission of pseudo paging. Various types of messages indicating that the incoming call is impossible may be set to be transmitted. The unreachable message may be stored in various forms in advance by a user in the sound source server 114 connected to the CSS 116 and then received. When the incoming call of the restricted calling terminal is transmitted to the corresponding calling terminal through the MSC 112. The COIS 124 refers to a server that manages various additional service information such as new opening and termination of subscribers and subscription of a call screen service according to the present invention.

2 illustrates an operation control flow for processing a call screen service in a mobile communication system according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when there is an incoming request from the mobile communication terminals in the mobile communication network to the called terminal registered in the call screen service (S200), the MSC 112 inputs the incoming request of the mobile communication terminal and the incoming call to the HLR 120. The request for location information including the calling party number of the calling party is requested (S202).

Then, the HLR 120 checks whether the MSC 112 sets a call restriction for the caller ID of the caller terminal, which has been called through the mobile communication network, and transmits the caller terminal caller number to the CSS 116 using the CSS 116. The transmission request is made to check the reception restriction registration for the calling terminal telephone number (S204).

Next, CSS 116 receives the reception restriction registration check request message for the calling terminal from the HLR 120 (S206), and the calling terminal number is registered with the reception restriction of each called terminal subscribed to the call screen service. After checking whether the reception limit is set by checking whether the mobile communication terminal is included in the mobile communication terminal, the reception limit registration information is provided to the HLR 120 (S208).

Accordingly, the HLR 120 receives the reception restriction registration response message from the CSS 116 and transmits the reception restriction registration information and the location information of the originating terminal to the MSC 112 (S210).

Then, the MSC 112 receives the reception restriction registration information for the calling terminal from the HLR 120 (S212), and if the calling terminal is a terminal registered in the reception restriction setting of the called terminal registered in the call screen service, the call is called. When the screen service is registered, a call forwarding message indicating that the call to the called terminal is impossible according to the call processing method set by the called terminal user is transmitted (S214). The unreachable message is a message informing that the incoming call cannot be stored in advance in the sound source transmission server according to the call processing method. For example, a default announcement message, VMS switching, automatic call termination, music transmission, and a message recorded by the user are transmitted. Various types of messages informing that the incoming call to the called terminal are not possible, such as sending out and sending out pseudo paging sounds, may be set to be sent.

Accordingly, the originating terminal 100 outputs a message of impossible to receive from the MSC 112 to the terminal user to inform that the incoming call to the called terminal is impossible (S216).

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, in the present invention, in a service for restricting reception of a specific caller number in a mobile communication network, a call screen of a called party is not ringed by registering a caller ID that is not desired to be received in a server to enable a call screen. Since there is no need to notify the caller of the password, there is an advantage that the caller can receive the call more conveniently and safely.
