Description

Method and apparatus for receiving mode control of mobile terminal using femtocell {METHOD AND APPARATUS FOR CONTROLLING RECEIVE MODE OF MOBILE TERMINAL USING FEMTO CELL}

The present invention relates to a technique for controlling an incoming mode of a mobile terminal, and more particularly, to a method and apparatus for receiving mode control of a mobile terminal for controlling the incoming mode of a mobile terminal located in a femtocell region.

The mobile terminal provides not only a voice call function but also a variety of additional functions such as wireless Internet function, MP3, and video playback function. These mobile terminals are rapidly spreading, and almost everyone owns them and becomes an essential portable device.

When the mobile terminal is equipped with various functions as described above and is in a place requiring quietness such as a conference room, an education place, a library, or the like, the mobile terminal is normally set to a vibration mode. This is because if the mobile terminal is set to ringing mode in a place requiring quietness, ringing occurs according to the incoming call, which causes discomfort to others.

However, the vibration mode or the ring tone mode of the mobile terminal is set by the user's direct manipulation, and many users forget to set the mobile terminal to the vibration mode when attending an unscheduled meeting or attending a sudden important presentation. Throw it away.

Accordingly, a method of forcibly converting a mobile terminal of a user who enters a restricted place requiring quiet such as a theater or a library into a vibration mode has been proposed. The following patent document discloses a system for forcibly switching a reception mode of a portable communication device of a user who has entered a specific place.

Meanwhile, due to the development of communication systems, various communication networks have been developed to support faster speeds and response rates. Among them, a femtocell communication network is a representative communication network.

Femto Cell (Femto Cell) is a technology that provides a mobile communication service to a region much smaller than the existing mobile communication radius through the femto base station (Femto AP). Femtocells are also used to guarantee the quality of mobile communication services in areas where shadows of the macro cell are degraded, such as at home or inside buildings, or in shaded areas. Used to relieve the load. In addition, femtocells are also used as a means of providing low rates through femtozone services. Furthermore, since femtocells use a universal Internet line for connection to the core network, the installation cost and maintenance cost are low, and the area where the Internet line is installed can be installed anywhere, so it has excellent mobility. .

In particular, the mobile terminals 210 and 220 set the incoming mode to the vibration mode or the silent mode, or the LCD brightness mode to the minimum brightness mode based on the mode change parameter included in the paging message transmitted from the femto base station 400. Set to. In addition, when the mobile station 210 or 220 receives the mode return message from the femto base station 400, the mobile station 210 or 220 changes the setting mode to the incoming mode or the LCD brightness mode before the change. In addition, the mobile terminal 210, 220 receives a call forced termination notification message from the femto base station 400 forcibly canceling the call connection, and outputs this notification message on the screen that the call connection with the specific user is forcibly terminated. It can also be made known to the user.

The macro base station 110 is a base station transceiver subsystem (BTS), a NodeB, an e-NodeB, and the like, and communicates with the mobile stations 210 and 220 through one or more frequencies and is controlled by the base station controller 120.

The base station controller 120 is a base station controller (BSC), a radio network controller (RNC), etc., and assigns and releases radio channels to the mobile stations 210 and 220, the mobile stations 210 and 220, and the macro base station 110.

The exchange 130 is a mobile switching center (MSC), a serving GPRS support node (SGSN), etc., and provides an interface function with the base station controller 120, and controls voice calls, data transmission and reception, and various additional services.

The location register 140 stores and manages subscriber profile information, additional service information for each subscriber, and location information of the mobile terminals 210 and 220.

The gateway 150 connects the wired broadband network 30 and the mobile communication core network, and the mobile terminal 210 connected to the femto base station 400 and the mobile terminal 220 connected to the mobile communication core network. Enable communication between them. In addition, the gateway 150 transmits data (for example, Internet content) received through the wired broadband network 30 to the mobile terminal 220 connected to the mobile communication core network. In addition, the gateway 150 transmits the data (for example, mobile content) received through the mobile communication core network to the mobile terminal 210 connected to the femto base station 400. In addition, the gateway 150 performs a protocol conversion function between the mobile communication core network and the wired broadband network 30.

The femto base station 400 is mainly for guaranteeing the quality of mobile communication service in the area or shadow area where the radio wave of the macro base station 110 is degraded, such as a home or a building, for providing a fast communication service, or a femtozone. A femtocell AP (Access Point) used for the purpose of providing a low rate, such as a service, is connected to the wired broadband network 30, which is a general-purpose Internet line. The mobile terminal 210 entering the femtocell 20 is connected to the femto base station 400 and is connected to a wired broadband circuit and a mobile communication core network through the femto base station 400.

Then, the femto base station 400 establishes a wireless connection with the called terminal 210 and transmits the call connection request message to the called terminal 210 (S213). Next, the called terminal 210 outputs information (eg, a lamp or vibration) indicating that the call is received without outputting a ring tone, and then transmits a response message to the femto base station 400 when the user inputs a call connection operation signal. (S215). Then, the femto base station 400 forms a communication path between the calling terminal 220 and the called terminal 210, so that the voice call is performed between both terminals 210 and 220 (S217).

Next, when the called terminal 210 receives the call termination operation signal from the called party, the called terminal 210 transmits a connection release message to the femto base station 400 (S219). Then, the femto base station 400 releases the call path formed in step S217 by transmitting a connection release message to the exchange 130 (S221). Subsequently, the femto base station 400 transmits a mode return message to the called terminal 210 (S223). Then, the incoming terminal 210 extracts the incoming call mode information and the screen brightness value from the memory in the memory, and changes the incoming call mode changed in step S209 to the incoming call mode before the change based on the incoming call mode information. Change to the brightness value before the change to return to the user-set mode (S225).

Meanwhile, the femto base station 400 may receive a connection release message from the exchange 130. That is, when the calling terminal 220 receives a call termination operation signal from the caller, the calling terminal 220 transmits a disconnection message to the switch 130, and the femto base station 400 connects the switch 130 to the call. Receive a release message. In this case, the femto base station 400 recognizes that the call is terminated and transmits a mode return message to the called terminal 210 to return the called mode of the called terminal 210 to the called mode set by the user.

Then, the exchange 130 confirms that the destination terminal 210 is located in the femtocell 20 through the location register 140, and transmits a call connection request message to the femto base station 400 (S303, S305).

Next, the femto base station 400 transmits a paging message to the called terminal 210 to perform a call connection between the calling terminal 220 and the called terminal 210 (S307). At this time, the femto base station 400 records the incoming mode change parameter for changing the incoming mode of the called terminal 210 into the silent mode or the vibration mode in the paging message and the screen brightness changing parameter for changing the screen brightness to the minimum brightness. Is additionally recorded in the paging message.

Then, the called terminal 210 changes its incoming mode to silent mode or vibrate mode based on the parameter recorded in the paging message, and also changes the screen brightness to the minimum brightness (S309). At this time, the called terminal 210 temporarily stores the incoming call mode information and the screen brightness setting value before the change in the memory. When the mode change is completed, the called terminal 210 transmits a paging response message to the femto base station 400 (S311).

Then, the femto base station 400 extracts the telephone number of the calling terminal 220 from the call connection request message received from the exchange 130 (S313). Subsequently, the femto base station 400 transmits a call failure message to the calling terminal 220 through the gateway 150 and the exchange 130 (S315). Preferably, the femto base station 400 requests the switch 130 to send out the voice call to the exchange 130, the switch 130 is a voice message indicating that the called party can not proceed to the call terminal ( 220). For example, the exchange 130, at the request of the femto base station 400, transmits a voice message to the calling terminal 220 such as "The caller is located in a place where the called party cannot answer. Please try again later." Can transmit

Next, the femto base station 400 transmits the notification message according to the interruption to the called terminal 210 to the called terminal 210 (S317). At this time, the femto base station 400 records the telephone number of the calling terminal 220 extracted in step S313 to the notification message. Preferably, the femto base station 400 may write the notification message in the SMS message standard, and then transmit the notification message to the called terminal 210 using a message center (not shown) of the mobile communication network. Then, the called terminal 210 does not output the ringtone, but notifies the user that the notification message has been received through screen activation, lamp lighting or vibration output. Accordingly, the user of the receiving terminal 210 can check who the call was received, and after the performance, lectures, etc., attempts to speak with the caller or immediately moves to a place where no damage is caused to others. A call can be attempted with the terminal 220.

Next, the femto base station 400 transmits the incoming mode return message to the called terminal 210 (S319). Then, the incoming terminal 210 extracts the incoming call mode information and the screen brightness value from the memory, and changes the incoming call mode changed in step S309 to the incoming call mode before the change based on the incoming call mode information.
