The communication technologies described below include code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), and single carrier-frequency division multiple (SC-FDMA). It can be used in various multiple access schemes such as access. CDMA may be implemented in radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. The TDMA may be implemented in a wireless technology such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). OFDMA may be implemented in wireless technologies such as IEEE (Institute of Electrical and Electronics Engineers) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Evolved UTRA (E-UTRA). UTRA is part of the Universal Mobile Telecommunications System (UMTS). 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution) is a part of E-UMTS (Evolved UMTS) using E-UTRA, adopting OFDMA in downlink and SC-FDMA in uplink.

4 is a diagram illustrating an example of a multiple radio access system.

Referring to FIG. 4, a multiple radio access system includes a base station 1100 and a plurality of communication devices 100, 1120, and 1130.

In FIG. 4, the devices 100, 1120, and 1130 denoted as communication devices are source devices and source devices which are connected to other communication devices and communicate with the base station with the help of other communication devices. ) May be a candidate cooperative device other than a cooperative device that serves as a relay that helps the base station communicate with the base station or a source device that does not serve as a cooperative device.

In a multiple radio access system, the plurality of communication devices 100, 1120, and 1130 may establish a cooperative scheme with each other. In a multi-radio access system in which a cooperative system is established, a source device can transmit data to a base station together with a cooperative device. Furthermore, the Source Device may receive data from the base station along with a cooperative device.

Here, a direct wireless communication scheme between a plurality of devices may be different from a direct wireless communication scheme between the base station and a plurality of devices. That is, data is transmitted and received by applying a wireless LAN connection method (e.g., Wi-Fi) between a plurality of devices, and a mobile communication network access method (e.g., IEEE 802.16 (WiMAX) Etc.) can be applied to transmit and receive data.

For example, a plurality of devices can directly communicate with each other according to an IEEE 802.11 (Wi-Fi) technology scheme or a Bluetooth technology scheme. On the other hand, each of the plurality of devices may directly communicate with each other using IEEE 802.16 (WiMAX) technology.

However, the present invention is not limited thereto, and a base station and a plurality of devices can communicate with each other according to the same wireless communication scheme.

Referring to FIG. 4, in a multiple wireless access system having a cooperative scheme, the source device 100 may transmit data to the base station 1100 together with the cooperative device 1130. As a result, the communication device can efficiently transmit data, thereby ensuring excellent performance. In addition, the throughput of each device can be enhanced through the multi-radio access system in which the cooperative system is established, and the effect of reducing the power consumption through the data communication through the cooperative system is also guaranteed.

Also, in a multi-radio access system in which a cooperative system is established, a source device can transmit data to a base station through a cooperative device. Furthermore, the Source Device may receive data from the base station via a cooperative device.

Referring to FIG. 4, in a multi-radio access system in which a cooperative scheme is established, the source device 100 may transmit data to the base station 1100 through the cooperative device 1120. This allows the communication device to efficiently transmit data, thereby preventing deterioration of system performance.

In FIG. 4, an example in which the source device transmits data to the base station through the cooperative device has been described, but the above description may also be applied when the base station receives data from the source device.

In addition, when transmitting other data, the source device 00 in FIG. 4 may be a cooperative device or a neighbor device not participating in the transmission of data, and the cooperative device 1120 and 1130 may also transmit the source device or data. It may be a neighboring device that does not participate in.

5 is a diagram illustrating an example of an operation of a multiple radio access system.

Referring to FIG. 5, a multiple radio access system includes a base station 1110 and a plurality of communication devices 1140 and 100.

In the multiple wireless access system, the plurality of communication devices 1140 and 100 may establish a cooperative scheme with each other through a wireless technology such as 802.11 (Wi-Fi).

In general, each of the plurality of communication devices 1140 and 100 may directly transmit or receive data through a base station 1110 and a wireless technology such as IEEE 802.16 (WiMAX).

In this case, when the current communication quality of the source device 100 is drastically reduced, the source device 100 may indirectly transmit data to the base station 1110 through the cooperative device 1140. In addition, the source device 100 may receive data indirectly from the base station 1100 through the cooperative device 1140.

Accordingly, in a multi-radio access system, a communication device can directly communicate data directly with a base station, indirectly communicate with the help of a cooperative device having excellent communication quality, Deterioration can be prevented and efficient data communication can be performed.

In a multi-radio access system, in order for a plurality of communication devices to cooperate with each other to transmit and receive data, a preliminary procedure for exchanging information in advance is required.

In the multi-radio access system, information exchange steps to be performed between a base station and a plurality of communication devices can be roughly classified into four steps. That is, it may include a general network entry step, a negotiation step for cooperation of a plurality of devices, a search for a neighboring device of the source device, a selection of a cooperating device among the discovered neighboring devices, and a connection to the selected cooperating device .

Meanwhile, in a multi-radio access system, a plurality of communication devices cooperate to communicate with each other by using an infrastructure basic service set (Infrastructure BBS) and an independent basic service depending on whether an access point (AP) is used. It can be divided into a set (Independent Basic Service Set (BBS)).

An access point (AP) refers to a connection point between a base station and a plurality of terminals in a multi-radio access system, and may be referred to as an interconnection point. For example, an access point (AP) is an intermediary between a wired LAN and a wireless LAN.

The access point may be referred to as an access point, an access point, an AP, etc., but for convenience of description, the access point will be referred to as an access point.

When using an access point in a multi-radio access system, a point-to-point function for connecting terminals located at two points to each other and communicating with each other may be provided.

Also, unlike the point-to-point function, a point-to-multipoint function that allows a plurality of connected terminals to communicate with each other by connecting a plurality of terminals at the same time may be provided.

 In addition, by wirelessly connecting to a base station and another access point (AP), it is possible to provide a repeater (Repeater) function to extend the data communication to the wireless area. That is, an access point (AP) configured as a repeater may communicate with another access point (AP) while providing a connection with a base station.

In addition, a wireless client ( Wireless) which is connected to a plurality of terminals capable of exchanging signals with a wired or near-field communication network, Client ) function may be provided.

FIG. 6 is a diagram illustrating a specific example of a basic service set (BSS) according to whether an access point is used.

FIG. 6A illustrates an example of an infrastructure basic service set (BBS).

In an Infrastructure Basic Service Set (BBS), a plurality of terminals perform communication using access points (APs).

The multiple wireless access system may include a plurality of access points (APs), and a plurality of terminals may exist around each of the plurality of access points.

6B illustrates an example of an independent basic service set (Independent BBS).

An independent basic service set (Independent BBS)), a plurality of terminals are directly connected to each other.

The foregoing includes both cases where a plurality of terminals are located within the coverage of each of a plurality of access points, connected wirelessly, or detected within a coverage area. That is, when the terminal and the access point are correlated, an Infrastructure Basic Service Set (BBS) can be implemented.

However, for convenience of explanation, it is assumed that each terminal is connected to each access point to constitute an infrastructure basic service set (Infrastructure BBS (Basic Service Set)).

An example of an infrastructure based service set is tethering technology. As one of the additional functions of the mobile terminal, the mobile terminal itself serves as a wireless modem is called tethering technology.

In other words, by connecting IT devices such as laptops, netbooks, tablet PCs, desktop PCs, e-book readers, PDAs to mobile phones via USB or Bluetooth devices, Wi-Fi, etc. This function can be used.

In order to use the wireless Internet in Korea, 3G (3rd generation mobile communication technology), WiBro (WiBro, high-speed wireless mobile Internet service), and a wireless LAN using a wireless access device should be utilized.

For example, the tethering service may utilize a 3G communication network as described above. Due to the nature of the 3G network, it is slower, more expensive, and more power-consuming than WiBro or WLAN. However, it can be accessed from anywhere in the mobile phone coverage area. In particular, when you want to send data to a laptop or netbook or search the Internet in areas where there is no wireless Internet, you only need a mobile phone that can use tethering.

On the other hand, when using the tethering (tethering) technology through the mobile terminal 100, the user has to inconvenience the need to enter the tethering network setting menu to set the contents.

Furthermore, when the LTE (Long Term Evolution) network is used, there is a problem that there are more tethering setting menus, more complicated, and less information provided to the user. That is, when setting the tethering function, only an icon indicating that the tethering function is used without displaying network information is often displayed.

In addition, there is a problem that the communication speed of the mobile terminal 100 connected to the lower side may be changed irregularly according to the access point to which the mobile terminal 100 can be connected.

Accordingly, the present invention is to provide a method for the base station and the mobile terminal 100 to communicate more quickly by changing the access point sequentially selected using the threshold communication speed.

Details of the present invention will be described with reference to FIG. 7.

FIG. 7 is a flowchart illustrating an example of performing communication using a threshold communication speed of sequentially selected access points according to an embodiment of the present invention.

Referring to FIG. 7, the mobile terminal 100 may receive a signal indicating the presence of a plurality of APs from a plurality of candidate APs through the wireless communication unit 110 (S710).

When receiving a signal indicating the presence of the plurality of access points, the controller 180 controls the list in which the plurality of access points are arranged in a predetermined form to be displayed in a predetermined region of the display unit 151 (S720).

When the list is displayed on the display unit 151, the user may sequentially select at least some access points using the user input unit 130 (S730). Access points selected according to the selected order are prioritized.

In this case, the user may sequentially select the first access point 811, the second access point 814, and the third access point 812 using the user input unit 130.

In this case, as shown in FIG. 8B, only the first access point 811, the second access point 814, and the third access point 812 may be displayed in a predetermined area of the display unit 151.

Although not illustrated, the controller 180 may control the first access point 811, the second access point 814, and the third access point 812 to be provided with a predetermined visual effect so that the selected order is divided. have. In this case, the predetermined visual effect may include at least one of color change, sharpness change, and transparency change.

Returning to FIG. 7, when at least some access points are selected, the user may input the threshold communication speed using the user input unit 130 (S740).

In this case, the unit of the critical communication speed may be mega bit per second (Mbps).

9A and 9B are diagrams illustrating an example of inputting a critical communication rate in accordance with an embodiment of the present invention.

First, referring to FIG. 9A, the controller 180 displays a first menu 910 for adding an access point and a second menu 920 for inputting a threshold communication speed in a predetermined area of the display unit 151. can do.

In this case, the user may select the second menu 920 using the user input unit 130 and input a communication speed in the threshold communication speed input window 921 as shown in FIG. 9B. For example, the user can set 2 Mbps as the threshold communication rate.

After the threshold communication speed is input, when the communication speed between the first access point and the first selected access point among the at least one selected access point and the mobile terminal 100 is equal to or higher than the set threshold communication speed, the controller 180 selects the first access point. Perform communication with the base station by using (S750).

However, when the communication speed is lower than the threshold communication speed during communication between the first access point and the mobile terminal 100, the controller 180 communicates with the second access point selected next to the first access point among the at least one selected access point. If the speed is greater than or equal to the threshold communication speed, communication with the base station is performed using the second access point (S760).

If the communication speed with the second access point is less than the threshold communication speed, the controller 180 determines whether the communication speed between the third access point and the mobile terminal 100 selected next to the second access point is greater than or equal to the threshold communication speed. You will be judged.

10A and 10B illustrate an example of performing communication using a new access point when a communication speed with a selected access point becomes less than a threshold communication speed while continuing communication in accordance with an embodiment of the present invention.

First, referring to FIG. 10A, the controller 180 communicates with a base station using a first access point 811 selected first among the plurality of selected access points 811, 814, and 812.

Subsequently, when the communication speed with the first access point 811 becomes less than the threshold communication speed, the controller 180 stops communication with the first access point 811 and with the next selected second access point 812. Detect communication speed.

If the detected communication speed between the second access point 812 and the mobile terminal 100 is greater than or equal to the threshold communication speed, as illustrated in FIG. 10B, the controller 180 communicates with the base station using the second access point 812. Do this.

Although not shown, the controller 180 controls the mobile terminal 100 to display a pop-up window for notifying that the mobile terminal 100 communicates with the base station using the second access point 812 in a predetermined area of the display unit 151. You may.

Therefore, the user can prioritize a plurality of access points that can be connected to the mobile terminal 100 without any manipulation, and can conveniently perform communication for the current environment using a threshold communication speed.

On the other hand, if there is a single access point selected by the user, the threshold communication speed may not be applied.

FIG. 11 is a diagram illustrating an example of a single access point selected in accordance with an embodiment of the present invention. FIG.

Referring to FIG. 11, the access point 812 selected by the user is singular. In this case, even when the communication speed between the selected access point 812 and the mobile terminal 100 is less than the threshold communication speed, the controller 180 may control to communicate with the base station using the selected access point 812.

This is to prevent interruption of communication between the mobile terminal 100 and the base station when the selected access point 812 is excluded from the communication.
