Description

Method and system for providing temporary refusal service {Method and system for providing extraordinary DND service}

The present invention relates to a Do Not Disturb (DND) service that allows a call to a user terminal to be prohibited at the request of a user. In particular, the present invention relates to a method and a system for providing a temporary refusal service to allow a refusal service to be set for a user-specified time and to terminate the refusal service by a general outgoing call of a user terminal.

As communication and calls using mobile communication networks have become commonplace, various kinds of call services have been provided. For example, a call service includes an incoming call service, a caller ID display service, a caller ID display restriction service, an anonymous call rejection service, and a Do Not Disturb Service (DND service).

Among these, the refusal service is a service that prevents incoming calls to the mobile phones of the first subscriber who set the refusal. Such a rejection service is disclosed in Korean Patent Laid-Open Publication Nos. 2006-0129762, 2007-0109368, 2005-0061945, and the like.

[0001] The present invention relates to a method for setting a call rejection in a mobile terminal. In the case where an incoming call is not received by granting a call rejection function (button) to a mobile terminal, a user sets a call rejection function to receive an incoming call. You can refuse.

Patent Publication No. 0109368 relates to a method for providing an incoming call rejection function and a mobile communication terminal, and allows a user to reject a call by setting a function to reject a call for a specific telephone number for a predetermined time. In addition, Patent Application Publication No. 061945 relates to a call rejection method using group information in a mobile communication terminal, wherein a call reception list is registered in a call reject list by registering a call rejector and a call reject time zone. Depending on whether the incoming time corresponds to the rejection time, the mobile communication terminal performs the rejection of the incoming call.

However, since the conventional rejection service provides the call rejection service in the mobile phone, there is a problem that the call rejection service cannot be provided in the mobile phone without the call rejection function. In addition, in the mobile communication system, the conventional rejection service does not reduce the load by performing all normal call processing processes in devices in all networks. In addition, the conventional rejection service has a problem in that a user needs to directly register and cancel the rejection service.

The technical problem to be achieved by the present invention is to enable a user to provide a refusal service for a time through a mobile communication network to all users. In addition, the technical problem to be achieved by the present invention is to enable the user to easily terminate the incoming call rejection service.

According to an aspect of the present invention, there is provided a method of providing a call rejection service to a first terminal. The method includes a first step in which a first exchange receives a first call signal transmitted from the first terminal, including a service special number and a user-specified valid time, by the first exchange to the first home location register. A second step of requesting a special number processing for an outgoing call; a third step of setting, by the first home location register, the rejection service for the first terminal to be valid during the valid time according to the service special number; and the incoming call While the rejection service is set up, when the first home location register receives the current location request corresponding to the call arrival to the first terminal, a fourth step of rejecting the call arrival to the first terminal is included.

In addition, the present invention according to another feature for achieving the above technical problem provides a temporary call rejection service system. The system is responsible for call processing, the exchange which makes a special processing request for the first outgoing signal upon receiving a first outgoing signal including a service special number and a user specified valid time from the first terminal, and the special processing request. According to the service special number included in the registration of the rejection service for the valid time, and receives the current location request corresponding to the call to the first terminal during the valid time call rejection to the first terminal It includes a home location register to indicate.

According to the above-described embodiment, the present invention is activated only during the time desired by the user to block the call to the user, and after the desired time has elapsed to allow the call to the user to allow the user to face the situation This allows flexible use of the refusal service.

In addition, the present invention enables to cancel the temporary refusal service simply by attempting a call to a third party while activating the temporary refusal service, thereby eliminating inconvenience caused by the service release.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

Now, with reference to the accompanying drawings will be described a method and system for providing a temporary rejection service according to an embodiment of the present invention.

First, the concept of the present invention will be described with reference to FIG. 1 is a conceptual diagram of a service for describing a poetic rejection service of the present invention.

Registration and termination of the rejection service (DND) according to the present invention is made by the mobile communication system 200, and the user informs the mobile communication system 200 of the desired time when the rejection service is requested, and the rejection service is maintained. Time (hereinafter referred to as "effective time") can be set.

Referring to FIG. 1, the user terminal 100 requests the mobile communication system 200 to set up a rejection service (S1), and together with the request (S1), the user terminal 100 transmits a valid time to the mobile communication system 200. Notify (S2).

When the mobile communication system 200 receives the valid time together with the request for setting the rejection service, the mobile communication system 200 sets the rejection service corresponding to the user terminal 100 to be maintained for the valid time (S3).

In FIG. 1, the rectangular box in the solid line shows that the refusal service is set during the effective time, and accordingly, the mobile communication system 200 performs the third party terminal 310, 320, during the effective time when the refusal service is set. In step 330, the call request to the user terminal 100 requested is rejected (S4).

On the other hand, the mobile communication system 200 automatically terminates the rejection service set during the validity time when the validity time elapses. The mobile communication system 200 terminates the call rejection service upon receiving the request for canceling the setting of the call rejection service from the user terminal 100 in the state where the valid time has not elapsed.

As another example, the mobile communication system 200 may automatically terminate the rejection service when a call from the user terminal 100 to any called party occurs in the state in which the valid time has not elapsed (S6). ).

Here, the mobile communication system 200 is a system of a second generation mobile communication network (eg GSM, CDMA, etc.), a system of a third generation mobile communication network (eg WCDMA), or a system of a 3.5 generation mobile communication network (eg HSPDA). It can be one.

Hereinafter, a mobile communication system 200 (hereinafter referred to as a "service system") for achieving the concept of the present invention will be described with reference to FIG. 2 based on a second generation mobile communication system. A service system according to an embodiment of the present invention will be described. 2 is a block diagram illustrating a request device of a service system according to an exemplary embodiment of the present invention.

The service system 200 according to an embodiment of the present invention is a general mobile communication system including a base station, an exchange, a home location register, and the like, but some devices have a separate function for the temporary refusal service of the present invention. .

That is, as shown in Figure 2, the service system 200 according to an embodiment of the present invention includes a switch 210 and a home location register 220 for the temporary rejection service of the present invention.

In addition to the general call processing function, the exchange 210 has a function of registering a user (or a specific terminal) requesting registration of the temporary rejection service in connection with the home location register 220 and corresponding to the termination of the temporary rejection service. .

In detail, the exchange 210 includes a call processor 211, a special processor 212, a DND manager 213, and a first timer 214.

The call processing unit 211 determines in connection with the home location register 220 through which path the call signal received from the caller is transmitted to the called party. If the service signal is included in the call signal, the call processing unit 211 causes the call processing unit 212 to process the call signal. Of course, if the general number does not include a special number in conjunction with the home location register 220 performs the call processing.

If the call processing unit 211 registers the temporary rejection service for any terminal, the call processing unit 211 monitors whether a general call is received from the terminal registered as the temporary rejection service for a valid time period, and if the general call is received, the call processing unit 211 sends it to the DND management unit 213. Inform.

The special number processing unit 212 generates a special request signal (Feature Request Message) for requesting the service special number processing and transmits the service special number to the home location register 220 of the terminal that sent the service special number, and responds to the special number request signal. Process the call. The special number processing request signal has a reserved field, and information of a valid time designated by a user is recorded in the reserved field. Of course, the special processing request signal includes at least unique identification information of the caller terminal.

The DND management unit 213 registers or deletes any user (or a specific terminal) as a target of the temporary rejection service in synchronization with the home location register 200 according to the instruction of the special number processing unit 212. When the DND management unit 213 registers the temporary refusal service for any user, the DND manager 213 drives the first timer 214 and registers the temporary refusal service when the time specified by the user is reached through the first timer 214. Delete it. The first timer 214 is driven by the DND management unit 213 to make a time counter.

Next, the home location register 220 manages the termination of the temporary refusal refusal service and the setting of the temporary refusal refusal service together with a function of identifying and providing a general called party's location.

In detail, the home location register 220 includes a location determiner 221, a special number analyzer 222, a DND service unit 223, and a second timer 224.

The location locator 221 detects the current location of the called party terminal using the unique identification information of the called party terminal and provides the current location to the exchange 210.

The special number analyzing unit 222 analyzes the special number included in the special number request signal received from the exchange 210, and grasps that the special number is a special number (hereinafter referred to as "service special number") indicating the setting of the temporary refusal service. .

The DND service unit 223 determines the valid time included in the special number processing request signal according to the instruction of the special number analyzing unit 222, and sets the temporary rejection service and the valid time by matching the unique identification information of the caller terminal. The DND service unit 223 monitors whether the valid time is reached by driving the second timer 224 with the setting of the temporary rejection service. The second timer 224 is driven by the DND service unit 223 to perform a time counter. In addition, when the DND service unit 223 requests a location from the third party terminal 300 to the user terminal 100, the user terminal 100 is set as the temporary rejection service target to the location determiner 221. Notify them that they do not receive a call.

On the other hand, the configuration of the switch 210 and the home location register 220 described above is a configuration corresponding to the case where the temporary rejection service is canceled by the outgoing call sent by the user terminal 100 in the state that the temporary rejection service is set to be.

In the case of using a feature code or using a separate identifier for the termination of the temporary refusal service, the exchange 210 does not have to have a separate configuration (ie, the DND management unit and the first timer) for the present invention. In this case, the present invention interprets the request (including the special number) requesting the termination of the temporary refusal service by the special number analyzing unit 222 of the home location register 220, and accordingly the corresponding user set in the DND service unit 223. Will terminate the temporary refusal service.

Hereinafter, a method of providing a temporary rejection service according to an embodiment of the present invention based on the service system shown in FIG. 2 will be described with reference to FIGS. 3 to 6.

First, referring to FIG. 3, a process of setting up a temporary refusal service according to a user's request in the method of providing a temporary refusal service according to an exemplary embodiment of the present invention will be described. 3 is a data flow diagram illustrating a process of processing a temporary refusal refusal service setting in a method of providing a temporary refusal refusal service according to an exemplary embodiment of the present invention. .

When the user terminal 100 inputs a service number indicating a DMS temporary refusal service and a valid time for keeping the temporary refusal refusal service to be registered, a call including a service special number (ie, a temporary refusal refusal service request) is removed. It is provided to the first exchanger (210a) (S302).

Here, the first exchange 210a becomes the originating exchange when the user terminal 100 is used as a reference.

When the call processor 211 of the first exchanger 210a receives the call signal, the call processor 211 checks whether a call number is included in the call signal (S303). If the call signal is included, the call processor 211 receives a call processing request signal through the call processor 212. It generates and transmits to the first HLR 220a (S304).

The special number processing request signal includes a service number, unique identification information of the user terminal 100, and an effective time. The first HLR 220a is an outgoing HLR that manages location information of the user terminal 100 when viewed from the position of the user terminal 100 that originated the call.

 The special number analyzing unit 221 of the first HLR 220a analyzes the service special number included in the received special number request signal (S305), and grasps that it is a request for setting the temporary rejection service (S306), and the DND service unit ( The valid time is determined through 223 (S307).

After the DND service unit 223 of the first HLR 220a sets the temporary rejection service and the valid time by matching the unique identification information of the user terminal 100 (S308), the second timer 224 is driven. The termination time of the temporary rejection service, that is, the time when the effective time is monitored (S309).

Thus, in response to the service number, the first HLR 220a that registers the user terminal 100 to the temporary rejection service transmits a signal indicating the completion of the special number processing to the first switch 210a in response to the special number request (S310). .

Accordingly, the DND manager 213 of the first exchanger 210a registers the call rejection service on with respect to the user terminal 100 (S311), and drives the first timer 214 to monitor the time when the valid time is reached.

On the other hand, the process of processing the setting of the temporary rejection service according to an embodiment of the present invention is modified in various forms according to the difference of the method of canceling the temporary rejection service according to the user's request.

That is, the process of setting up the temporary refusal refusal service according to an exemplary embodiment of the present invention may terminate the temporary refusal refusal service only by the user who sets the temporary refusal refusal service as described with reference to FIG. 3. A first service termination method, a second service termination method, and the like, in which a temporary rejection service is terminated by using a feature code.

The process of processing the setting of the temporary rejection service according to the first service canceling method is the same as that described with reference to FIG. 3, and the process of processing the setting of the temporary rejection service according to the second service canceling method is performed in step S311. And does not require the S312 process.

Here, the second service cancellation method is generally similar to the process of FIG. 3, wherein the special number is a special number requesting the termination of the temporary refusal refusal service, and the first HLR 220a terminates the setting of the temporary refusal refusal service according to the special number. .

Hereinafter, referring to FIG. 4, a temporary call rejection service providing method according to an exemplary embodiment of the present invention will be described. 4 is a data flow diagram illustrating a method of providing a temporary rejection service according to an embodiment of the present invention.

The user sets a temporary call rejection service to the first HLR 220a which is the home location register of the user terminal 100 using the user terminal 100 (S401) (see FIG. 3).

At this time, if the user designates the validity time as 2 hours, the temporary rejection service is maintained for 2 hours from the moment it is set.

When the temporary rejection service is set for the user terminal 100 as described above, the present invention rejects the call to the user terminal 100 during the effective time.

Specifically, when any third party calls the user terminal 100 using its terminal 300 (S402), the first HLR 220a is a user terminal in response to the location request of the second switch S403. Using the unique identification information of the 100 to determine the current location of the user terminal 100 (S403, S404), the user terminal 100 to determine that the temporary call-back rejection service is registered (S405). Accordingly, the first HLR 220a notifies the second exchange 30 of the call rejection in response to the location request (S406), and the second exchange 30 terminates the call (S407).

In addition, when the temporary refusal service is terminated after the effective time of 2 hours has elapsed, the present invention normalizes the incoming call to the user terminal 100 so that a call can be established between any third party terminal 300 and the user terminal 100. (S408, S409, S410, S411, S412, S413).

Hereinafter, the first service cancellation method will be described with reference to FIGS. 5 and 6.

Prior to the description, in order to terminate the temporary rejection service according to the first service termination method, the user terminal 100 registers with the temporary rejection service at the exchange receiving the call request (that is, the outgoing call) of the user terminal 100. It must be understood. When the originating exchange that receives the outgoing signal of the user terminal 100 does not know whether or not the temporary rejection service is registered with the user terminal 100, the outgoing exchange does not use the first HLR 220a that is the home location register of the user terminal 100. This is because the general call processing procedure is performed by accessing the home location register of the third party terminal 300. That is, the originating exchange receiving the outgoing signal of the user terminal 100 needs to know the registration of the temporary rejection service for the user terminal 100 to access the first HLR 220a and request the termination of the temporary rejection service. .

However, since the user terminal 100 is often moved according to time, the exchange which receives an outgoing signal is changed. Therefore, there is a need for information management that allows the user terminal 100 to store registration information of a temporary refusal service in any exchange that receives an outgoing call in response to the movement of the user terminal 100.

A method of managing registration information of a temporary rejection service between exchanges in response to a change in the location of the user terminal will be described with reference to FIG. 5. FIG. 5 is a data flow diagram illustrating a process of managing an incoming call rejection service registration information set in an exchange according to a change of a location of a user terminal according to an exemplary embodiment of the present invention.

When the user terminal 100 requests the temporary rejection service to the first HLR 220a through the previous switch 201 (S501 and S502), the first HLR 220a may request the temporary rejection service of the user terminal 100. It registers as a subject and notifies the previous switch 201 (S503).

Then, the previous exchange 201 registers that the user terminal 100 is registered with the temporary refusal service for the validity time according to the service registration notification received from the first HLR 220a, and is temporarily limited to the first HLR 220a. Synchronize the information on the rejection service (S504).

Subsequently, when the user terminal 100 moves (or handovers) a position and requests registration of the current position through the current exchange 202, the current exchange 202 requests the first HLR 220a of the user terminal 100. Inform the current position (S506).

When the first HLR 220a receives the location request, the first HLR 220a identifies the unique identification information of the user terminal 100 included in the location request signal, and the user terminal 100 uses the identified unique identification information of the user terminal 100. It is checked whether or not it is registered in the temporary refusal service (S507).

If it is confirmed through the checking process (S507) that the user terminal 100 is registered in the temporary rejection service, the first HLR 220a registers the current location of the user terminal 100 and then responds to the location registration request. In this case, the switch 202 is notified that the user terminal 100 is registered with the temporary rejection service during the valid time (S508). Here, the first HLR 220a provides the current trainer 202 with the time counted by the first timer 224 to synchronize the valid time count with the current exchange 202.

Then, the current exchange 202 registers the temporary rejection service with respect to the user terminal 100 and drives the first timer 214 to monitor the valid time (S509).

 On the other hand, if the user terminal 100 leaves the area in which the first HLR 220a is in charge, the current location of the user terminal 100 is not the first HLR 220a, but the VLR (Visitor Location Register) of the corresponding area. ) Will be registered. However, even if the current location is registered in the VLR, the first HLR 220a is notified that the current location of the user terminal 100 is registered in the VLR. Therefore, the first HLR 220a always knows that the location of the user terminal 100 has been changed, and accordingly, it can inform that the temporary rejection service for the user terminal 100 is currently registered in the exchange 202.

Here, of course, the first HLR 220a notifies the switch 202 that the user terminal 100 is currently registered with the temporary refusal service, and the user terminal 100 registered with the previous switch 201. Instructs the deletion of the temporary refusal service registration information.

Hereinafter, referring to FIG. 6, a second service canceling method according to an exemplary embodiment of the present invention, that is, a temporary rejection service canceling method, will be described. 6 is a data flow diagram illustrating a method of canceling a temporary rejection service in a method of providing a temporary rejection service according to an embodiment of the present invention.

The user terminal 100 registers the temporary rejection service with the first HLR 220a as an effective time of 2 hours (S601).

In this state, when the user terminal 100 calls for a call with the third party terminal 320 (S602), the first switch 210a confirms that the user terminal 100 is registered in the temporary refusal service. (S603), the service cancellation request is made to the first HLR 220a (S604), and at the same time, the current state of the third party terminal 310 is transmitted to the second HLR 220, which is the home location register of the third party terminal 320 (S604). The position is requested (S605).

When the first HLR 220a receives the service termination request signal, the first HLR 220a terminates the registration of the temporary rejection service for the user terminal 100 (S606), and the service cancellation request for notifying that the service has been terminated to the first exchange 210a. Send a response (S607).

Accordingly, the first exchange 210a deletes the registration of the temporary rejection service for the user terminal 100 (S608).

In addition, the second HLR 220b detects the current position of the third party terminal 320 according to the position request of the first exchanger 210a (S609), and informs the first exchanger 210a of the user terminal 100. ) And a call is made between the third party terminal 320 (S610 and S611).

Therefore, when the user terminal 100 makes a call request within the effective time of the temporary refusal service, the temporary refusal refusal service is terminated, and after termination, any third party terminal 310 is terminated as shown in FIG. 6. When the user terminal 100 is called within the valid time, a call is made between the third party terminal 310 and the user terminal 100 (S612 to S615).

The embodiments of the present invention described above are not only implemented by the apparatus and method but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded, The embodiments can be easily implemented by those skilled in the art from the description of the embodiments described above.
