Abstract

PURPOSE: A method for reporting an extrinsic service enable state to a mobile terminal is provided to previously prevent termination from being not made continuously by informing a subscriber's terminal that the presently enabled extrinsic service is hindering termination to the subscriber terminal. CONSTITUTION: In case that a subscriber moves to another cell or switches on his terminal(11), the terminal sends a location registration request message to the MSC(12) of the present cell(2-j). The MSC(12) analyzes the message and transmits a registration notification signal to a VLR(13)(2-k). The VLR(13), in case that the subscriber's location registration is made within the coverage of the VLR(13), executes registration processing according to the registration notification signal and transmits a response signal to the MSC(12)(2-n). In case that the subscriber's location registration is made from the outside of the coverage of the VLR(13), the VLR(13) sends a registration notification signal to an HLR(14)(2-l). The HLR(14) carries out processing for the subscriber's location registration according to the registration notification signal from the VLR(13) and transmits a response signal to the VLR(13)(2-m). At this moment, if the subscriber's extrinsic service is in an active state, the VLR(13) transmits this state to the MSC(12) together with the response signal(2-n).

Description

Method for Informing Activation State of Additional Service to Terminal In Mobile Communication}

The present invention relates to a method of notifying an additional service active state from a mobile communication to a terminal. More specifically, a call is made to a terminal for a long time to the user's site by notifying that an additional service such as call forwarding or call rejection is currently activated. It's about how to lose.

Many additional services are currently provided to users in mobile communication networks. These additional services can activate or deactivate the service function according to the user's intention after registering the additional service application with the operator, and also can register / change / delete / query the additional information required for each additional service.

The activation / deactivation of the supplementary service is performed by the subscriber directly by using the supplementary code or by the operators at the request or operational purpose of the subscriber. The additional code is a code designated for recognition of the additional service for each additional service and may be differently designated for each mobile communication service company.

1 illustrates an additional service processing procedure using an additional code in a conventional mobile communication.

As shown in FIG. 1, the subscriber first sends the supplementary code to the mobile switching center of the cell to which the subscriber belongs through the terminal for activating / deactivating the supplementary service (1-a). Receiving the additional code, the mobile exchange determines that the additional code is an additional code, and transmits the additional function request signal to the home location register of the subscriber station sending the additional code (1-b). This is because the additional service information of the subscriber should be stored in the home location register of the subscriber terminal, so that the home location register is notified and processed. The home location register analyzes the additional function request signal received from the mobile switch, and confirms whether the additional code corresponds to which additional service, and whether the additional code is a signal for activation or a signal for deactivation. The analyzed information is stored in the database of the home location register and transmits a response signal to the additional function request signal to the mobile switch (1-c). However, if the additional code sent by the subscriber corresponds to the additional service not registered by the subscriber, the additional code fails. The mobile exchange receiving the response signal from the home location register analyzes the response signal and notifies the subscriber terminal of the processing result (1-d). In some cases, the notification method simply uses a tone, and in some cases, the announcement of the contents of the notification is made. If the supplementary service requested by the subscriber is to activate call forwarding or call rejection, the mobile switcher disconnects the call to the subscriber station (1-e).

As described above, when the state of the supplementary service is changed by the subscriber's request, the visitor location register which temporarily manages the subscriber's information at the current location of the subscriber is not stored only in the home location register. In the Visitor Location Register), additional service information of the subscriber may need to be registered. This is different for additional services. (1-f) to (1-i) of FIG. 1 illustrate this procedure. After the additional service information is registered in the home location register by the subscriber, the home location register transmits the authority data command signal to the visitor location register (1-f). The visitor location register receiving the signal from the home location register registers additional service information of the subscriber and transmits a response signal to the home location register (1-g). In addition, the visitor location register transmits the authority data command signal to the mobile exchange for the registered data, and the visitor exchange sends a response signal to the mobile exchanger (1-h, 1-i).

As described above, when the additional service information of the subscriber is changed, the additional code is used by the subscriber in most cases, but there is a case where the information change is requested through the customer center of the operator. In this case, unlike the case of using the additional code, there is no special difference from the case of using the additional code except that the additional service information is registered in the home location register directly in the customer center without passing through the mobile exchange.

Additional services provided by the mobile communication network include additional services such as call forwarding and call rejection. When this supplementary service is activated, incoming calls are not made to the subscriber station. In the event that a subscriber encounters any special purpose or special situation, there may be cases in which these services are activated to temporarily prevent interference from the telephone. Often you forget to activate it and never disable it again. According to the above-described prior art, there is no method of informing the subscriber of the activation state of the supplementary service, so that the subscriber does not receive a call until the subscriber recognizes the supplementary service activation state.

In the present invention, in order to solve the problems of the prior art as described above, if the activated additional service corresponds to a service that does not make a call to the subscriber's terminal, by notifying the subscriber's terminal, the subscriber terminal continuously I would like to propose a way to prevent the incoming call in advance.

1 is a diagram illustrating an additional service processing procedure using an additional code in a conventional mobile communication;

2 illustrates a method of notifying an additional service activity state when a subscriber moves from location to location;

3 illustrates a method of notifying an active state of an additional service when a subscriber attempts to make a call to a terminal.

In order to achieve the above object, in the mobile communication according to the present invention, the additional service activation status notification method to a terminal moves or registers or transmits a location movement when a subscriber moves or attempts to make a call through the terminal. Requesting to the exchange (a); (B) performing location registration and origination processing according to the subscriber request of step (a), and transmitting supplementary service activity status information of the subscriber station to the mobile switchboard; And (c) notifying the subscriber station of the additional service activation state received in step (b).

On the other hand, when there is a subscriber's location movement, the location registration and additional service activation state transmission in step (b) may include: transmitting, by the mobile exchange, a registration notification signal to the visitor location register for location registration; If the subscriber requesting the registration is a subscriber managed by the visitor location register, the subscriber registers the location registration, grasps the additional service activation status of the subscriber, and adds the detected additional service activation status information to the response signal for the registration notification. Transmitting to the mobile exchange, including; If the subscriber who requested the registration is not a subscriber managed by the visitor location register, the home location register requests the location registration to the home location register to which the subscriber terminal belongs, and the home location register processes the location registration and includes the subscriber's additional service active state. And transmitting a response signal to the notification of registration to the visitor location register, wherein the visitor location register transfers it to the mobile exchange.

On the other hand, when there is an outgoing subscriber, the originating and additional service active state transmission of step (b) may include: performing a corresponding outgoing process when the mobile switch has the subscriber information including the additional service active state; If the mobile exchange does not have subscriber information including an additional service active state, requesting it from a visitor location register, wherein the visitor location register sends the subscriber information to the mobile exchange; If the visitor location register does not have subscriber information including an additional service active state, the visitor location register requests this to a home location register, the home location register sends the subscriber information to the visitor location register, and the visitor location register And transmitting the received subscriber information to the mobile exchange.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the method for notifying the additional service active state to the terminal in the mobile communication according to the present invention.

In the embodiment of the present invention, the active state of the supplementary service proposes a method of notifying when the subscriber attempts to make a call or when the subscriber moves to a location. It is not limited to.

2 illustrates a method of notifying an additional service activity state when a subscriber moves.

In FIG. 2, the procedure of (2-a) to (2-i) is a process of activating an additional service by a subscriber as in the prior art, and thus proceeds in the same manner as in the prior art. Therefore, I will not duplicate the explanation.

Location registration occurs when a subscriber moves from a cell of a mobile communication network in which a subscriber is currently located to another cell, or turns off a terminal and turns it back on. At the time of location registration, the terminal 11 first sends a message requesting registration to the mobile switching center 12 of the current location (2-j).

The mobile switch 12 analyzes the message to determine that the message is a request for location registration, and transmits a registration notification signal to the visitor location register 13 performing the location registration process of the subscriber (2-k).

The visitor location register 13 operates differently depending on whether or not the location registration of the subscriber is made in its own area. If the location registration is made within the area of the visitor location register, the registration process according to the change of the subscriber's location is performed according to the registration notification signal, and the mobile switch 12 transmits the response signal according to the registration notification signal (2-n). ).

When the location registration is made outside the area of the visitor location register 13, the visitor location register 13 sends a registration notification signal to the home location register 14 to which the subscriber terminal belongs, requesting location registration processing (2-l). .

The home location register 14 performs processing for the subscriber's location registration according to the registration notification signal from the visitor location register 13, and transmits a response signal to the visitor location register 13 (2-m). ).

In the case where the visitor location register is directly processed by the visitor location register as well as the home location register, the visitor location register is notified of the registration of the subscriber to the mobile exchange. When transmitting the response signal indicating that the location has been registered to the mobile switching center 12, if the additional service of the subscriber is active, this status is included in the response signal and transmitted together (2-n).

The mobile exchange 12 may analyze the response signal from the visitor location register 13 to determine that the subscriber's supplementary service is active, and inform the subscriber's terminal that the supplementary service is active (2-o). According to a preferred embodiment of the present invention, it is preferable to use a short message when notification of the active state of the additional service. The short message may be transmitted directly from the mobile switching center 12 to the terminal, or alternatively, the short message center may be used to notify the additional service activation state. When a short message is sent through the short message center, the short message is stored in the short message center and needs to be transmitted when the terminal is ready to receive the short message. According to another embodiment of the present invention, the active state of the additional service may be notified through Pip Tone.

In the above description, the method of notifying the additional service activation status when registering a location of the terminal will be described below.

3 illustrates a method of notifying an active state of an additional service when a subscriber attempts to make a call to a terminal.

In FIG. 3, the procedure of (3-a) to (3-i) is a process of activating an additional service by a subscriber as in the prior art, and thus proceeds in the same manner as in the conventional art.

The outgoing through the subscriber's terminal begins by sending an outgoing signal to the mobile switch 12 of the cell to which the terminal belongs (3-j). The mobile switch 12 analyzes the signal from the terminal 11 to determine the calling number and the calling party number, and performs the calling process using the caller's subscriber information.

If the caller's subscriber information does not exist in the mobile switchboard 12, the mobile switchboard sends an authorization data request signal to the visitor location register 13 to request the subscriber information including whether the additional service is activated (3-k). .

When the visitor location register 13 has subscriber information, the visitor location register 13 includes the subscriber information in the response signal for the authorization data request and transmits it to the mobile switch 12 (3-n). If the visitor location register also does not have subscriber information, the visitor location register 13 transmits the authority data request signal to the home location register 12 to which the terminal belongs (3).

The home location register 14 analyzes the authority data request signal received from the visitor location register 13 and transmits subscriber information of the corresponding subscriber to the visitor location register (3-m). The visitor location register transfers the received subscriber information to the mobile switch (3-n). This signal becomes the response signal to the authority data request signal of the mobile exchange.

Since the subscriber information includes information on whether the supplementary service is activated, the mobile switcher can check whether the supplementary service such as call forwarding or call forwarding is activated when the call processing is performed using the subscriber information. . When the supplementary service such as call forwarding or call rejection is activated, the mobile switch 12 proceeds to call processing (3-o), and notifies the originating subscriber's terminal of the active state of the supplementary service (3). -p). The notification method may be notified through a short message or via a pipton as in the case of the above-described location change. As in the case of FIG. 3, the short message may be transmitted directly from the mobile switch 12, or may be transmitted through the short message center.

In the above embodiment, a case where the subscriber changes the location and attempts to make an outgoing call has been described as an example. However, when using the intelligent mobile communication network, it is possible to notify the subscriber of the desired time or the active state of the periodic additional service.

As described above, according to the method of notifying the additional service activation status to the terminal in the mobile communication according to the present invention, when the subscriber is activated to the additional service such as call forwarding or call rejection, the incoming call to the terminal is prohibited. By notifying the subscriber of the active state of the additional service, there is an advantage that the subscriber can recognize the fact that the call is not received and allow the subscriber to take appropriate measures.
