VOICE CALL RESTRICTION SYSTEM AND METHOD FOR MOBILE COMMUNICATION TERMINAL}

The present invention relates to a voice call blocking system and method of a mobile communication terminal, and more particularly to a voice call blocking system and method of a mobile communication terminal to selectively block only a voice call without a user's operation in a place where voice call blocking is required. It is about.

As the users of mobile communication terminals increase rapidly, many people have come to carry the mobile communication terminals. As a result, side effects due to the use of the mobile communication terminal are also generated, and ringtones or voices that are indiscriminately generated in public places are representative problems that may cause discomfort to others.

The noise caused by these mobile communication terminals is more problematic in places where quietness is required. Noise generated in places where concentration is necessary, such as movie theaters, libraries, various performance halls, presentation halls, churches or courts, can cause considerable damage to others. Can be.

Therefore, in these places, the use of the mobile communication terminal is banned, but noise is often generated inadvertently or intentionally by the user.

Various methods for preventing noise caused by the mobile communication terminal have been proposed, some of which will be introduced.

First of all, a method of totally prohibiting the use of a mobile communication terminal includes installation of a device that may interfere with communication of the mobile communication terminal or designing a structure such that a radio signal cannot pass through a building structure. However, in this case, since the radio call is prevented at the source, it is impossible to contact in an emergency, and since the communication with the base station is not possible, the power consumption of the mobile communication terminal is increased, the communication output is high, and the device is overheated and generates a lot of electromagnetic waves. . In addition, the cost of changing the structure of the building is expensive, there is a limit to the structure.

As another method, there is a method of activating a conference mode applied to a mobile communication terminal. When the conference mode is activated for the purpose of blocking a ringing by a voice call or an incoming call, a voice call from an external device can be blocked. However, in this case, a call made by the user who set the conference mode is not blocked and a problem arises in that the user must manually set the conference mode. This is the same problem that occurs even when the mobile communication terminal is set in the silent mode.

As another method, there is a method of newly designing a terminal to block transmission and reception when the mobile communication terminal belongs to a predetermined area, or a method of determining a location of the terminal to block transmission and reception of a voice call. Since the terminal and the base station equipment cannot be used as it is, it is difficult to generalize.

Therefore, there is a need for a new system and method that can use existing terminals and base station equipment as is, and to enable the use of a message service or a data communication service as it is, and to prevent the transmission and reception of voice calls in order to ensure the validity of an emergency or contact. .

As described above, in order to prevent ringtones and voices that are indiscriminately ringing in places where quietness is required, a device that prevents or blocks radio waves is installed in the place or the place is constructed in such a way that wireless communication is impossible. Since the wireless communication is cut off at the source, it is not only impossible to contact in an emergency, but also has a problem in that a lot of load is generated in the communication device. In addition, although the user may be induced to operate the terminal in the non-receiving mode, there is a problem that can not prevent the transmission of voice calls, noise occurs if the user does not operate, and newly designed terminal or communication network in a specific place Although it is possible to prevent the voice call, there is a problem that the practical application is impossible because it is not effective for the existing devices.

In view of the above problems, the present invention uses the existing mobile communication terminal and communication network as it is, and stores the terminal information located in the area in the base station in charge of the area where the voice call should be limited, and whether or not the voice call for the terminal And a method for controlling a voice call of a mobile communication terminal to enter a voice call restriction area and to restrict a voice call transmission and reception for a terminal in which information is stored in the means added to the base station. The purpose is to provide.

The present invention for achieving the above object is to receive and store the location information of the mobile communication terminal entering a specific area, block the call so that the voice call is not received in the mobile communication terminal and the voice call originated from the mobile communication terminal A voice call controller for blocking the call; Register the location of the mobile communication terminal entering a specific area belonging to its own area and provide it to the voice call controller, and if voice call transmission / reception is necessary, contact the voice call controller to determine whether to block the voice call according to the result. It characterized in that it comprises a base station for determining.

It is characterized in that it further comprises a voice call register that is disposed in the specific area, and connected to the mobile communication network connected to the base station or the voice call controller to determine whether the voice call controller has made a voice call.

In addition, the present invention provides a voice call blocking method of a mobile communication terminal using a voice call controller added to a base station in charge of a specific area in which a voice call is restricted, when the mobile communication terminal enters the specific area. Communicating by a base station to perform location registration, and storing the information in the voice talk controller; When the voice call connection is requested from the outside through the communication network to the mobile communication terminal in the area of the base station, the voice call controller is inquired whether to block the voice call, and according to the result, the voice call targeting the terminal entering the specific area Blocking and informing the sender of the facts; If the mobile communication terminal in the specific area attempts to make a voice call, searching for mobile communication terminal information stored in the voice call controller and blocking the voice call if the terminal exists; And when the mobile communication terminal leaves the specific region, the terminal and the base station communicate with each other to release the location registration, thereby deleting the terminal information stored in the voice talk controller.

When the mobile communication terminal information is registered in the voice call controller or removed from the voice call controller, and when voice call transmission / reception occurs for the mobile communication terminal registered in the voice call controller, the processing result is moved. And notifying the communication terminal in a text message.

When described in detail with reference to the embodiments of the present invention as described above.

Figure 1 shows a simple configuration of the present invention, for illustrating the concept of the present invention. The present invention prevents a mobile communication terminal belonging to a specific area from receiving or making a voice call. This function will be referred to as a public example mode, that is, a public polite mode, and will be referred to as a PPM.

Such a specific region is called a PPM zone 30, and a mobile communication terminal entering the specific region will be referred to as a PPMS 10. In addition, the equipment additionally added to the existing base station 40 managing the area including the PPM zone 30 to perform the voice call-related processing is referred to as a PPM controller (PPMC) 45.

That is, the minimum component for the present invention is a public switched telephone network (PSTN) 60 for managing wired and wireless communication with respect to an external mobile communication terminal 70b or a wired terminal 70a, and control thereof. Any base station 40 connected to the station 50, an additional PPMC 45 connected to the base station 40, a PPM zone 30 and the PPM zone to which voice calls will be controlled by the PPMC 45; PPMS 10 located at 30. The illustrated PPMR (PPM Register) 20 is a means for determining the operation of the PPMC 45, an independent device connected to the PPMC 45, the base station 45 or the control station 50 by a network Although it may be, the manager who manages the PPM zone 30 may indirectly request to control the operation of the PPMC 45 by making a call to the wireless network manager or a service center through wired or wireless communication.

The PPMC 45 is connected to the base station 45, stores the information of the PPMS 10 provided by the base station 45, and then, the PPMS 10 from the voice call transmitted and received through the base station 45 ) As a reception target or to block transmission from the PPMS 10.

For this operation, when the PPMS 10 enters the PPM zone 30, the base station 40 needs to know the fact. Therefore, whether or not the PPMS 10 enters the PPM zone 30 is performed by location registration occurring between the PPMS 10 and the base station 40. The base station 40 can know the location of the terminal. It is possible to use one or more of a variety of methods. For example, a method of tracking the location of a mobile communication terminal through a satellite or various base stations (using GPS), and a method of identifying a mobile communication terminal entering / exiting a specific area after designating a specific area as a user area (user Various methods may be used, including using a user zone.

Now, in order to explain the operation of the present invention according to the specific operation method and situation of the PPMC 45 used in the present invention will be described with reference to the accompanying drawings according to the embodiments according to each situation.

FIG. 2 is a signal development diagram illustrating a registration and external signal processing procedure according to an exemplary embodiment of the present invention.

First, when a predetermined terminal enters the PPM zone, the terminal 10 and the base station 40 communicate with each other so that the location of the terminal 10 is registered in the base station 40. This is a step in which the base station 40 recognizes that the location of the terminal 10 belongs to the PPM zone. This may be implemented through various positioning methods as described above, and this function is already implemented in the current communication network.

The base station 40 requests registration of the PPM function together with the information of the terminal 10 to the PPMC 45 connected to the information of the terminal 10 registered as described above. The PPMC 45 receives the terminal information (telephone number or unique number, etc.), stores the information in the internal memory, and informs the base station 40 that the PPM function of the terminal 10 is registered. The base station 40 informs the terminal 10 that has entered the PPM zone through a short message, and the user of the terminal 10 can confirm that his terminal is operated in the PPM mode.

In this case, when an external voice call is requested for a terminal registered with the PPM function, that is, the PPMS 10, the voice call request from the external wired / wireless terminal 70 is transmitted to the base station of the region where the PPMS 10 is located. 40), the base station 40 operates in the PPM mode of the terminal targeted to the PPMC 45 before processing the corresponding voice call (you can know the type of the call by looking at the service option of the call). The PPMC 45 searches for terminal information stored in a memory and provides a PPM mode activation confirmation signal to the base station 40 if the PPM mode is activated. Since the base station 40 can confirm that the target of the requested voice call is currently operating in the PPM mode, the base station 40 blocks the voice call, and guides the result to the external wired / wireless terminal 70 requesting voice call connection. In this case, the corresponding PPMC 10 is informed that there is a voice call request through a short message service. Of course, this specific known method may be variously changed or omitted.

If a message service or data service call for a terminal registered with the PPM function is required, since the call service is not a voice call, the normal service is performed as in the prior art regardless of the PPM function.

Then, the outgoing signal processing procedure from the terminal registered with the PPM function will now be described with reference to FIG. 3.

When the voice call origination is requested from the PPMS 10 operating in the PPM mode as shown, the base station 40 receiving the voice call origination request before the PPMC 10 processes the voice call origination request. 45, inquires whether the PPMS 10 requesting the call is operating in the PPM mode, and the PPMC 45 confirms that the PPMS 10 registered in the PPMC 45 is the PPMS 10 operating in the PPM mode. The base station 40 cuts off the voice outgoing signal requested from the PPMS 10 and notifies the PPMS 10 in a short message. Of course, this known method may be changed or omitted.

If the message transmission or the data service call request from the PPMS 10 is received by the base station 40, the process is performed as before.

When the PPMS 10 is out of the PPM zone, the base station 40 can recognize this, and requests the PPMC 45 to release the PPM function together with the information of the corresponding terminal. Upon receiving the request, the PPMC 45 deletes the information of the corresponding terminal from the memory and provides the base station 40 with the PPM mode release confirmation signal. Accordingly, the base station 40 informs the terminal outside the PPM zone through the short message service that the PPM function has been released.

Through the above basic operation description, it would be possible to understand the operation method of the PPMC, the base station, and the PPMS. Although the present invention may operate normally with only the above description, an additional function that enables the PPM zone administrator to activate or deactivate the PPM function in the PPM zone may be further applied to the system of the present invention, thereby activating the PPM function accordingly. And an operation procedure of deactivation.

4 is an operation procedure when the PPMR 20 directly or indirectly connected to the PPMC 45 is installed in the PPM zone so that the PPM zone manager can control whether the function of the PPMC 45 is activated.

First, when the PPM zone manager transmits a signal requesting activation of the PPM function for the PPM zone managed by the PPM zone by using the connected PPMR 20, the PPMC 45 which is not yet activated is transmitted to the base station 40. Require subscriber information to register). The base station 40 provides the PPMC 45 with information of terminals located in the PPM zone managed by the base station 40, and the PPMC 45, having received the information, stores the information in its memory, and then the PPM subscriber. Notifies the base station 40 that registration is complete. Then, the connected PPMR 20 notifies that the PPM function of the corresponding PPM zone is activated, and sends a short message indicating that the PPM function is activated to all registered PPMS 10.

If the PPM zone manager wants to deactivate the PPM function for the PPM zone managed by the PPM zone manager, the PPMC 45 transmits a signal for requesting deactivation of the PPM function to the PPMC 45 using the PPMR 20. ) Deletes the information of the PPMS 10 stored in its memory, informs the base station 40 that the PPM subscriber release is completed, and then sends a short message to all of the deleted PPMS 10 informing that the PPM function has been deactivated. (At the base station), it informs the connected PPMR 20 that the PPM function of the corresponding PPM zone is deactivated.

Therefore, in the case of using the system of the present invention described above, the communication function except for the voice call can be made effective, and only the incoming and outgoing call of the voice call causing noise can be selectively controlled, thereby enabling more effective and flexible use of the mobile communication terminal. .

As described above, the voice call blocking system and method of the present invention store the terminal information located in the area in the base station in charge of the area where the voice call should be restricted while using the existing mobile communication terminal and the communication network. And adding a means for controlling whether or not to transmit or receive a voice call to the terminal, and enters the voice call restriction area so that the voice call transmission and reception for the terminal in which information is stored in the means added to the base station is restricted. It is possible to effectively block only incoming and outgoing voice calls that can cause noise while maintaining the network function to be used, and there is no effect of changing the terminal, thereby providing a highly practical mobile terminal limitation system at low cost.
