Description

Manner Mode Switching Apparatus and Method in Private Mobile Communication Network

The present invention relates to a manner mode switching apparatus and a method thereof, in particular, when a user moves from a public mobile communication network to a private mobile communication network, a base station of a private mobile communication network located in a court or a performance hall is forced to operate in a mobile communication terminal. The present invention relates to a manner mode switching device and a method in a private mobile communication network to be switched to silent mode.

Recently, with the development of mobile communication, the use of mobile phones has become more common and the supply has increased exponentially. However, this leads to various problems. In particular, indiscriminate ringtones in public places can be said to infringe public interests.

In general, the mobile phone ring tone can be adjusted by pressing several function buttons on the mobile phone itself. Therefore, the user selects the ring tone according to the taste of the mobile phone user.

However, such a mobile phone ringtone may cause inconvenience in public places.

In other words, cell phone ringtones in public places, such as the suspension of trial in court due to cell phone ringtones and the case of the player's refusal to play due to noise outside the common sense in concert, are becoming various social problems.

In order to solve the above problems, a mobile phone communication breaker has been already developed or developed to disable mobile phone ringtones by disturbing transmission and reception of mobile phones and radio calls to radio waves in a limited space not only in the US and Japan but also in Korea. .

Such a cellular communication circuit breaker will be described briefly. First, when a user having a mobile phone installed in a restricted space enters a restricted space, the cellular communication circuit breaker emits a frequency wave such as a cellular phone to disturb the reception function of the radio receiver inside the cellular phone.

In other words, the mobile phone blocks the incoming call as well as the outgoing call using the principle that the mobile phone cannot distinguish between the radio wave of the mobile communication service provider and the radio wave breaker within the limited space.

However, the blocking of the communication of the mobile phone by the jamming is contrary to the universal right that the user can enjoy the convenience of communication and is against the public interest.

In addition, there is a problem that a situation in which a user having a mobile phone blocked by jamming does not contact when an emergency situation occurs at home or at work.

In order to solve this problem, a "method of automatic mode switching using Bluetooth in a mobile phone" of the domestic application number 10-1999-0034536 has been developed.

The disclosed "method for automatically switching to silent mode using a Bluetooth in a mobile phone" is to automatically switch an alarm mode of a mobile phone to a silent mode in a public place requiring quietness using Bluetooth wireless communication. A method for automatically switching a mode of the mobile phone to silent mode by performing a Bluetooth wireless communication with a mobile phone equipped with a module, the Bluetooth communication device collecting information of all mobile phones located within a communication radius through Bluetooth wireless communication. And transmitting a manner mode switching request data packet from the Bluetooth communication device to each mobile phone of the collected information, and changing the mode to the manner mode in each mobile phone receiving the manner mode switching request data packet from the Bluetooth communication device. Automatic switching process It characterized by true.

In addition, a "portable communication device having a mode switching function and a mode switching control system" of Korean Patent Application No. 10-2002-0000490 have been developed.

The disclosed "portable communication device having a mode switching function and a mode switching control system" relates to a portable communication device capable of setting an appropriate call mode according to a use environment, and is not familiar with noise of a mode switching signal for switching a call mode. Receiving means for receiving from an external transmitter installed at a place; And a mode switching means for detecting a current call mode state when the mode switching signal is input from the receiving means, and switching the current call mode to an environmentally friendly mode when the current call mode is a sound mode. It automatically changes the calling mode of all portable communication devices entering and leaving an unfamiliar place to the environment-friendly mode, so that it is possible to prevent the discomfort of people around by the ringing sound.

On the other hand, recently, a private mobile communication service system has been developed in which a wired subscriber and a mobile communication service subscriber can make a call without being charged in the same building (the conventional mobile communication service system is called a public mobile communication service system). To distinguish it from a private mobile communication service system).

The developed private mobile telecommunication service system is connected to other mobile telecommunications subscribers or private exchanges registered in the private telecommunication service system without additional charge in the area where private telecommunication service is registered. By extension, they can receive each other's call service.

Since the private mobile communication service system described above is generally installed in a building, the service is often provided in a limited area, and therefore, it is good to provide a manner mode switching service when it is installed in a court or a performance hall.

Accordingly, the present invention has been made in order to meet the above needs, when a user moves from a public mobile communication network to a private mobile communication network, a base station of a private mobile communication network located in a court or a performance hall is forcibly operated with respect to a mobile communication terminal. It is an object of the present invention to provide a manner mode switching device and a method in a private mobile communication network that can switch from mode to silent mode.

Characterized in that the made up.

In addition, the present invention provides a method of switching to the manner mode applied to a mobile communication service system including a mobile communication terminal and a private base station supporting a private mobile communication service, the mobile communication terminal in the public dedicated cell area public / private shared cell A first step of transmitting a location registration update message to the private base station when moving to an area; A second step of performing, by the private base station, location registration when the mobile communication terminal requests a location registration update by moving to a public / private shared cell area; A third step of determining, by the private base station, the position of the mobile communication terminal and transmitting a manner mode switch signal when the mobile communication terminal is located in a restricted area; And a fourth step of switching from the alert mode to the silent mode when the silent mode switch signal is received from the private base station.

1 is a network diagram illustrating the concept of a public and private mobile communication service to which the present invention is applied.

In an embodiment of the present invention, as shown in FIG. 1 to provide a public and private mobile communication service, a public / private shared cell area 14, which is a public and private shared communication service area, is provided. The public / private communication service device 12 is provided.

The public / private shared cell area 14 is preferably defined to benefit a particular group of communications services.

For example, if a particular company is using one building, the area to which the building belongs may be designated as the public / private shared cell area 14.

Determining the public / private shared cell area 14 is preferably done in consultation with a public telecommunication service provider.

This is for the private base station (private BTS) 8-k in the public / private shared cell area 14 to be recognized as a public base station from the perspective of a public mobile communication system.

In the present specification, a base station (BTS) belonging to a public mobile communication system, that is, the BTSs 6-1, 6-k, and 8-1 shown as an example in FIG. 1 and a public / private shared cell area In order to distinguish the private base station 8-k in (14), the private base station 8-k is referred to as' pBTS (private BTS).

The pBTS 8-k, together with the MS 24 belonging to the public / private shared cell region 14, performs functions of configuring a wireless communication path and managing radio resources, and perform a public / private communication service device 12. It is connected to the BSC of the public mobile communication system, for example, the BSC (4-m) shown in FIG.

The pBTS 8-k sends a system parameter message through the paging channel to all MSs belonging to the public / private shared cell area 14 to distinguish it from the BTSs 6-1, 6-k and 8-1. When broadcasting to (24), broadcast a specific bit on.

In this way, the MS 24 supporting the private mobile communication service can see that a specific bit of the system parameter message is turned on and thus enter the public / private shared cell area 14, and thus the public / private shared cell area 14 When the MS 24 detects that the mobile station has entered a message, the MS 24 sends a newly defined location registration update message (for example, a signal of turning on a reserved specific bit of the location registration update message) when the location registration update message is transmitted. k).

The pBTS 8-k, which has received a specific location registration update message from the MS 24 supporting the private mobile communication service existing in the public / private shared cell area 14, locates the MS 24. (PBTS #, Sector #) transmits a silent mode switch signal when the determined position is a silent mode setting region. This manner mode switching signal may be achieved by setting a predefined value in the IS-95 Information Records Field of the Feature Notification message. In doing so, the MS 24 automatically switches to silent mode if a predefined value is set in the IS-95 Information Records Field of the Feature Notification message.

As such, the pBTS 8-k is installed in a building where the use of the MS 24, such as a hospital, an airport, and a performance hall, is limited and passes through the public / private shared cell area 14 where the pBTS 8-k is installed. 24) transmits a silent mode switch signal.

The public / private communication service device 12 is connected to the BSC (4-m), the PSTN / ISDN 16, and the IP network (Internet Protocol Network) 18 of the public mobile communication system.

The public / private communication service device 12 selectively provides public mobile communication service and private mobile communication service to MSs in the public / private shared cell area 14, for example, to the MS 24 of FIG. Perform mobile communication service to be possible.

If the MS 24 is registered in the public / private communication service device 12 to receive a private mobile communication service, the MS 24 may receive a private mobile communication service as well as a public mobile communication service. Can be.

However, if the private mobile communication service registration for the MS 24 is not in the public / private communication service device 12, the MS 24 may receive only the public mobile communication service.

In addition, the MS 24 switches to silent mode when a silent mode switch signal is received from the pBTS 8-k.

The public / private communication service device 12 also performs a wired communication service with the PSTN / ISDN 16 and the IP network 18.

On the other hand, a public mobile communication network is commonly referred to as a public land mobile network (PLMN), and an example configuration of the public mobile communication system is shown in FIG. 1, wherein a plurality of mobile switching centers (MSCs) ( 2-1, .., 2-n), a plurality of base station controllers (BSC: 4-1, .., 4-m), a plurality of base stations (BTSs) (6-1, .., 6-k, 8-1, .., 8-k), Mobile Stations (MS: 22,24), and HLR / VLR (Home Location Register / Visitor Location) Register) 10.

A plurality of BSCs 4-1, ..., 4-m are connected to each of the plurality of MSCs 2-1, ..., 2-n, and a plurality of BSCs 4-1, ..., ... 4-m) A plurality of BTSs 6-1, ..., 6-k, 8-1, ..., 8-k are connected to each other.

In particular, pBTS (8-k) is connected as one of a plurality of BTS (8-1, ..., 8-k) connected to the BSC (4-m) of the public mobile communication system according to an embodiment of the present invention have.

Each of the plurality of MSCs 2-1, .., 2-n may connect a plurality of BSCs (eg, 4-1, .., 4-m) connected to the PSTN / ISDN (Public Switch Telephone Network / Integrated). Control access to other MSCs in the Services Digital Network) or public mobile communication network.

Each of the plurality of BSCs 4-1, ..., 4-m performs radio link control and handoff functions, and each of the plurality of BTSs 6-1, ..., 6-k, 8-1,. .8-k), together with MSs 20, 22, and 24 belonging to its own communication service area, that is, its cell area, perform a function of configuring a wireless communication path and managing radio resources.

In the HLR / VLR 10, the HLR performs a subscriber location registration function and a database function for storing subscriber information, and the VLR is in charge of a corresponding MSC among a plurality of MSCs 2-1, .., 2-n. It is a database that temporarily stores information of the MS existing in the cell area.

If the MS moves to a cell area managed by another MSC, the information stored in the VLR is deleted.

In the present specification, in order to distinguish the public / private shared cell area 14, the communication service area of the BTSs 6-1, .. 6-6-k, 8-1, .. This is called a public dedicated cell area.

1 illustrates a communication service area of a BTS 8-1 among BTSs 6-1, ..., 6-k, 8-1, ... of a public mobile communication system. 15).

Typically, the public dedicated cell area 15 is much wider than the public / private shared cell area 14 that is intended to benefit a particular group of communications services.

Now, with reference to Figure 1 will be described in detail a preferred embodiment of the present invention.

When the idle MS 24, which is powered on, enters the public / private shared cell region 14 of pBTS 8-k, the pBTS 8-k indicates that the MS 24 is a public / private shared cell region. Detecting presence in 14, the pBTS 8-k sends a silent mode switch signal to the located MS 24.

That is, pBTS 8-k transmits a location registration value different from BTSs 6-1, .. 6-k, 8-1, and pBTS 8-k transmits BTSs 6-k. 1,, 6-k, 8-1) to turn on a particular bit when broadcasting a system parameter message through the paging channel to all MSs 24 belonging to the public / private shared cell area 14. (on) to broadcast.

Allow the idle MS 24, which is in a powered-on state, to enter the public / private shared cell region 14 of pBTS 8-k from BTSs 6-1, ..., 6-k, 8-1. PBTS 8-k can grasp this MS 24 through a method of location registration update.

The MS 24 performs location registration update according to various criteria, among which zone-based location registration is a location registration zone value of the location registration zone value transmitted by the pBTS 8-k and the current location stored in the MS 24. If the location registration zone values are different from those in the list, the location registration update is performed through the control channel to pBTS (8-k).

In addition, the MS 24 supporting the private mobile communication service can see that the specific bit of the system parameter message is turned on, so that the MS 24 enters the public / private shared cell area 14, and thus the public / private shared cell area 14 When the MS 24 detects that the mobile station has entered a message, the MS 24 sends a newly defined location registration update message (for example, a signal of turning on a reserved specific bit of the location registration update message) when the location registration update message is transmitted. k).

At this time, the location registration message transmitted by the MS 24 to the pBTS 8-k includes the terminal identification number / terminal electronic serial number (MIN / ESN) of the MS 24.

When the pBTS 8-k detects that the MS 24 exists in the public / private shared cell area 14, the pBTS 8-k transmits a manner mode switching signal to the MS 24. Transmit with electronic serial number (MIN / ESN).

This manner mode switching signal may be achieved by setting a predefined value in the IS-95 Information Records Field of the Feature Notification message.

When the MS 24 receives a silent mode switch signal from the pBTS 8-k, the MS 24 switches to the silent mode, in which the MS 24 sets a predefined value in the IS-95 Information Records Field of the Feature Notification message. If it is, it automatically switches to silent mode.

In the context of the present invention, the silent mode is used in a sense corresponding to the alarm mode, the alarm mode means a mode for notifying that the call is coming to the ringtone or melody, and thus, the silent mode is a vibration mode for notifying the vibration of the call, It doesn't even notify you that you have a phone call, but when it is in silent mode, it means sleep mode.

FIG. 2 is a configuration diagram of pBTS of FIG. 1.

Referring to the drawings, pBTS is a signal receiving unit 30 for receiving the position registration update signal through the control channel transmitted from the MS, and the terminal position for detecting the presence of the MS from the position registration update signal received by the signal receiving unit 30 When the MS is detected by the grasping unit 31 and the terminal position detecting unit 31, the control unit 32 generates a mode switching signal by controlling the corresponding mode switching signal generating unit 33 so that the MS switches to the silent mode. And a mode switching signal generation unit 33 for generating a manner mode switching signal, a transmitter 34 for transmitting a manner mode switching signal generated by the mode switching signal to the MS, and a position registration updating unit 35.

The pBTS detects the presence of the MS when the MS enters the public / private shared cell area through the terminal location determiner 31.

The idle MS sends a message to the pBTS requesting a location registration update when entering the public / private shared cell area of the pBTS, and the busy MS sends a message to the BTS requesting handoff.

At this time, the pBTS broadcasts a specific bit on when broadcasting a system parameter message to all MSs belonging to the public / private shared cell area through a paging channel so as to be distinguished from the BTSs.

In this way, the MS supporting the private mobile communication service can see that a specific bit of a system parameter message is turned on and thus enter the public / private shared cell area. When transmitting a registration update message, a newly defined location registration update message (for example, a signal for turning on a reserved specific bit of the location registration update message) is transmitted to the pBTS.

Accordingly, the pBTS detects that the terminal exists in the public / private shared cell area by the handoff function through the location registration update function received through the signal receiver 30.

When the MS requests the location registration update from the pBTS, the terminal position detecting unit 31 detects the existence of the MS and applies it to the control unit 32, and the control unit 32 knows the existence of the MS.

When the MS registers the location by the location registration updater 35, the controller 32 determines the location of the MS (BTS #, Sector #), and if the determined location is the manner mode setting area, the mode switching signal generation unit. The controller 33 generates a manner mode switching signal and transmits the generated manner mode switching signal to the MS through the transmitter 34.

At this time, the manner mode switch signal may be achieved by setting a predefined value in the IS-95 Information Records Field of the Feature Notification message.

That is, when the MS receives a silent mode switch signal from the pBTS, the MS switches to silent mode. In this case, the MS automatically switches to silent mode when a predefined value is set in the IS-95 Information Records field of the Feature Notification message. Perform.

3 is a configuration diagram of the MS of FIG. 1.

The control unit 40 controls the general operation of the MS, and transmits a location registration update signal when moving to the public / private shared cell area of the pBTS, and controls the mode switching unit 58 when a manner mode switching signal is received. Switch to silent mode.

The memory 44 stores a predetermined program that controls the overall operation of the mobile phone, and stores data input and output and various data processed while the program is being executed.

The duplexer 48 communicates with the base station through the antenna so that the signal from the transmitter 50 is transmitted to the base station through the antenna, and the signal from the base station through the antenna is received by the receiver 52.

The receiver 56 is controlled by the controller 40 and receives a radio signal output from the duplexer 48. The transmitter 50 transmits the modulated radio signal from the audio unit 54 to the duplexer 54.

The audio unit 54 is controlled by the control unit 40, modulates the voice signal input through the microphone (MIC) into a radio signal, and demodulates the radio signal received through the receiver 52 to the speaker (SP) The audio signal is sent to the camera.

In addition, the audio unit 54 detects the ring signal through the receiver 56 when the ring signal is generated from the base station and transmits the ring signal through the ringer. Accordingly, the user acoustically confirms that a ring signal is generated from the base station.

The key input unit 42 includes a numeric key, a voice mailbox switching key, and various function keys. When the user presses a predetermined key, the key input unit 42 generates a corresponding key input signal and outputs it to the control unit 40. The display unit 46 controls the control unit. Controlled by 40, a key input signal generated by the key input unit 42 and various information signals from the control unit 40 are received and displayed.

At this time, the display unit 46 is composed of a liquid crystal display (LCD) for displaying a variety of information. The voice synthesizer 56 reads the voice data corresponding to the automatic response guide message from the memory 54 under the control of the controller 40, synthesizes the voice signal into a voice signal, and outputs the voice signal to the audio unit 54. The audio signal corresponding to the business message inputted from 54 is analyzed and stored in the memory 54.

Now, look at the operation of the MS with reference to Figure 3 as follows.

When the idle MS in the power-on state enters the public / private shared cell area of the private base station from the public base station, the control unit 40 stores the location registration value of the current location being stored and the location registration area value received from the private base station. In comparison, the private base station requests a location registration update using a control channel. At this time, the location registration update message transmitted to the private base station by the control unit 40 includes a terminal identification number / terminal electronic serial number (MIN / ESN).

In addition, the control unit 40 may determine that a specific bit of the system parameter message transmitted from the pBTS is turned on and enter the public / private shared cell area. When transmitting a registration update message, a newly defined location registration update message (for example, a signal for turning on a reserved specific bit of the location registration update message) is transmitted to the pBTS.

On the other hand, when receiving a location registration update response message from the private base station, the control unit 40 controls the mode switching unit 58 to switch to the silent mode when the manner mode switching signal is included.

That is, the controller 40 switches to the silent mode when the silent mode switch signal is received from the pBTS. In this case, the MS automatically sets the silent mode when a predefined value is set in the IS-95 Information Records field of the Feature Notification message. To perform the conversion.

In addition, the control unit 40 displays a message informing the display unit 46 that the mobile station is forcibly switched to the silent mode (for example, "currently moving to the silent mode application area, and automatically switches to the silent mode.")

4 is a flowchart illustrating a manner mode switching method according to an embodiment of the present invention.

Referring to the drawing, first, pBTS transmits a location registration value different from that of a general base station. In this case, pBTS, unlike BTSs, broadcasts a system parameter message to all MSs belonging to the public / private shared cell area through a paging channel. The specific bit is turned on for broadcasting (step S10).

Subsequently, when the idle MS in the power-on state enters the service area of the pBTS from the public base station (step S12), the MS determines the location registration area list of the location registration area value transmitted by the pBTS and the current location stored in the MS. If the location registration zone value is different from the value and the specific bit of the system parameter message is turned on, the specific location registration update message is transmitted to update the location registration through the control channel to the pBTS (step S14).

In this case, the location registration update message transmitted to the pBTS by the MS includes the terminal identification number / terminal electronic serial number (MIN / ESN) of the MS.

When the PBTS receives the specific location registration update message from the MS, the pBTS performs the location registration update and then detects the location of the MS (step S16), and transmits a manner mode switching signal to the MS if the determined location is a manner mode setting area. (Step S18). At this time, the manner mode switching signal may be achieved by setting a predefined value in the IS-95 Information Records Field of the Feature Notification message.

Thereafter, when the MS receives a silent mode switch signal from the pBTS, the MS switches to silent mode, and the MS automatically switches to silent mode if a predefined value is set in the IS-95 Information Records field of the Feature Notification message. Do this.

On the other hand, the MS determines whether it has left the public / private shared cell area (step S22), and if it has left the public / private shared cell area, it releases silent mode (step S24).

Although the present invention has been described in detail with reference to preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims.

According to the present invention as described above, when a person possessing a mobile communication terminal moves to a restricted area of the mobile communication terminal, the private base station detects the location of the terminal and transmits a manner mode switching signal through a control channel. By switching to silent mode, it is possible to prevent others from being harmed by the terminal.
