Description

Termination call limited system in public facilities of cellular network

The technology to which the invention belongs and the prior art

The present invention is a device similar to the base station 110 applied to a mobile communication network (GSM / CDMA / WCDMA, etc.), the call is installed in public places (schools, performance halls, meeting rooms, etc.) in the mobile communication network to reach the subscribers in the public place It is an incoming call limiting device (110-1) that automatically limits and supports to provide a caller to the caller, a text message to the caller.

The current CDMA mobile communication network consists of the systems as shown in FIG. 1 to provide a service.

The base station 110 performs a function of connecting the mobile communication terminal 100/200 and the control station 120, is wirelessly connected to the terminal 100/200, and is connected to the control station 120 by wire.

The control station 120 manages / controls the base stations 110, interworks with the exchange 130 for voice calls, and interworks with the data core system 160 for data services.

Switch 130 is responsible for call processing by translating the number of mobile communication subscribers, the control station 120, the visited location register 140, home location register 150, intelligent network equipment 170, short message server 180 ), The voicemail system 190 and the like.

The visited location register 140 may be located in the exchange 130 or may be separated, and manages information of subscribers located in the area of the exchange 130.

The home location register 150 records and manages information on the subscriber in association with the exchange 130 and the visited location register 140.

4 shows an incoming and outgoing call procedure in the current mobile communication network.

The mobile communication terminal 100/200 registers a location with the home location register 150 through the base station 110 periodically while the power is turned on (401).

The home location register 150 receives the location information of the current terminal and records which base station 110 is present in the area (402). Among the subscriber information stored in the home location register 150, the location information is recorded only in which base station 110 an area exists.

If any caller 100 attempts to make a call (403), the exchange 130 requests the home location register 150 for the information of the called party 200 (404) and the caller 200 receives the exchange ( In step 130, a paging message is delivered to the called party without any restriction (405) and the incoming call is connected (406).

Therefore, the called party 200 is ringing in the school, a performance hall, a meeting room, etc., during a performance, or during a meeting, the ringing bell rings and the incoming call is made to disturb others or interfere with important tasks.

The present invention is a device for preventing incoming calls or incoming calls by automatically limiting incoming calls even if the mobile communication subscribers do not directly turn off the terminal or switch to the vibration mode in such a public place.

The present invention is added to an existing mobile communication network as shown in FIG.

The present invention is manufactured in a very small wall-mounted type to be easily installed in public places and installed on the wall, and the output is adjusted by cell planning to be limited to the range of incoming calls. In addition, when the incoming call limiter 110-1 is installed, an ID (ID for classifying a school, a performance hall, a conference room, etc.) is set according to the characteristics of a public place to be installed.

The hardware of the apparatus is configured in the same form as the existing base station 110. However, it should be a 1FA / OMNI Type Micro Base Station according to the features installed in public places.

It is manufactured in the form of small-capacity, ultra-small base station composed of RF unit 301, digital radio unit 302, modem unit 303, interface unit 304, processor unit 305, etc. suitable for mobile communication system. You should add an ID that provides the functionality but identifies the characteristics of the public space.

Approximate configuration of the apparatus is shown in FIG.

The RF unit 301 is a part that interworks with the terminal 100/200 wirelessly, performs antenna connection, Amp function, and the like.

The digital radio unit 302 performs IF (Intermediate Frequency) up / down conversion, analog / digital conversion, and the like.

The modem unit 303 performs a function of demodulating data with the terminal 100/200.

The interface unit 304 implements functions for matching between the base station 110 and the control station 120.

The processor unit 305 performs a call processing function control, an operation maintenance function, and the like for the base station 110.

In order to provide call restriction service in public places by using this device, some software change of existing mobile communication system is required.

Identification code (ID, namely school, performance hall, conference room) of the call forwarding device 110-1 in the location registration message of the base station controller 120, the exchange 130, the visited location register 140, and the home location register 150. ID) for distinguishing and the like), and the switch 130 restricts the incoming call according to the location information of the called subscriber and transmits the guided broadcast, and attempts to call in conjunction with the short message system 180. You need to add features that let you send information about text messages.

It will be described in detail with reference to Figures 2 and 5 below.

The incoming call limiting device 110-1 installs the incoming call communicating service in a desired public place in the same manner as the existing base station 110 is installed in the current mobile communication network as shown in FIG. 2. At this time, the base station 110 in charge of the public place area and the incoming call limiting device 110-1 in the public place occupy the general base station 110 by the mobile communication terminal 100/200 in the public place through cell planning. On the contrary, the mobile communication terminal 100/200 outside the public place should not occupy the incoming call control device 110-1.

5 shows a call processing procedure when an incoming call is attempted to a public place where the incoming call limiting device 110-1 is installed.

When a registration signal for location registration is generated in the mobile communication terminal 200 entering the area of the incoming call limiting device 110-1, the incoming call limiting device 110-1 receives this signal and exchanges the exchange 130 through the mobile communication network. ), Together with the terminal information, the visited location register 140 and the home location register 150 transmits an ID (ID for distinguishing a school, a performance hall, a conference room, etc.) together with the terminal communication device (501).

The exchange 130 registers the location information transmitted from the device to which the incoming call is connected to the visited location register 140, and the visited location register 140 registers subscriber information to the home location register 150 again (502). . In this case, the location registration message transmitted between the exchange 130, the visited location register 140, and the home location register 150 should be provided with an identifier for distinguishing the ID of the device for which the incoming call has been made.

The terminal which has completed the location registration in the terminating call restriction device 110-1 is provided with the call restriction function until it leaves the area.

If any caller 100 attempts to make a call to the called party 200 in a public place where the called call device 110-1 is installed (504), the calling party exchange 130 converts the called party 200 number. In operation 505, the home location register 150 requests information about the called party 200 to obtain the location information of the called party 200.

After confirming that the called party 200 is located in the area of the called party call device 110-1, the exchange 130 provides the called call service without transmitting a paging message to the called party 200. In other words, the announcement broadcast to the caller 100 to the ID of the device (110-1) for the call-talking device ("Currently can not answer the phone because you are in class," or "Currently can not answer the call") In step 506, the announcement broadcasting apparatus is controlled to transmit the " In addition, in conjunction with the short message system 180, the caller 100 controls the sender 100 and the calling time information to be sent to the caller 200 as a text message (507).

However, even if it is within the area of the incoming call limiting device 110-1, the outgoing call of the subscriber 100 should not be limited in case of an urgent outgoing call or an outgoing call.

In addition, when the subscriber (100/200) in the area of the incoming call limiting device (110-1) of the public place moves out of the area is registered through the existing base station 110, the normal incoming call is made without restriction.

Radio blocking devices may be installed to solve the inconvenience caused by cell phone ringing and call sound that are often ringing in public places such as schools, performance halls and conference rooms. However, this equipment cannot be installed as an illegal device under related laws.

However, the present invention does not block the radio waves and operates according to the general mobile communication call procedure, and automatically restricts the ringing tone and the incoming call only in public places. In addition, the caller 100 can know the situation that the called party 200 does not receive, the caller 200 can not only check the information on the call that has been sent to them, but also turn off the terminal or switch to the vibration mode to others There are advantages that do not cause inconvenience.
