BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

In order to provide users with a wider range of data in a complex wireless communication network composed of different heterogeneous networks, the user should be able to easily use a connection environment and have to decide which wireless network to use.

It is an important issue in the mobility access control technology for this purpose to provide policy information to the terminal in consideration of how to make decisions and optimize the switching of the wireless network.

The present invention is a scenario of how to collect the state of each wireless network in the composite wireless communication network, predict the traffic congestion from the collected information and how to run which terminal using the traffic information based on the usage of the terminal The invention is about providing.

The present invention provides an apparatus and method for allowing a terminal to predict congestion of traffic in a composite wireless network without entailing complicated procedures between the terminal and the composite wireless network or excessively consuming resources (battery and CPU load) of the terminal. do.

1 is a diagram illustrating a network configuration of a terminal control apparatus for data offload of the present invention.

FIG. 1 illustrates a data offload in a hybrid wireless network in which a mobile station (MS) 110 is composed of a heterogeneous network of a third generation network (3G) (WCDMA) 130 and a Wi-Fi (WiFi) 120. Offload) is a view showing a configuration for detecting the area in one embodiment.

The data offload area is a complex wireless network in which heterogeneous networks are mixed, and an area in which a switch to another wireless network is required when the traffic of the wireless network that the terminal accesses and receives a sudden increase in traffic cannot receive normal service. it means.

In the data offload area, the terminal should be able to receive the service continuously by switching the wireless network.

The terminal control apparatus 100 for data offload of the present invention receives location information of a base station and a terminal from a location based service (LBD) system 170, and an operation support system (OSS). Support Systems) 180 receives network state information, i.e., traffic information.

The mobile station 110 transmits its location information and status information to the terminal control apparatus 100 for data offload, and the terminal control apparatus for data offload. Receive information on whether to switch the wireless network and the repeated connection attempt period from the (100).

2 is a diagram illustrating an embodiment of a terminal control process for the data offload of the present invention.

In the present invention, the terminal control apparatus for data offload (100 in FIG. 1) is primarily based on the base station-based position from the LBS system 170 until the position of the terminal requesting registration is approached near the offload area. Are provided.

The base station determines whether the base station corresponds to a data offload region based on the received base station location information.

The mobile station (MS) 110 sends the context information to the terminal control device (100 of FIG. 1) for data offload or provides information according to a predetermined pattern according to a predefined state.

It describes a data offload area detection discovery process considering the relationship between the location of the terminal and the base station.

A mobile station (MS) 110 in a state of using a wireless network transmits its primary location information and state information to a terminal control device (100 of FIG. 1) for data offload.

The terminal control apparatus (100 in FIG. 1) for data offload determines the policy and the repetition attempt period for the wireless network switching according to whether the mobile station 110 belongs to the offload region. do.

If the MS (Mobile Station) 110 does not belong to the Offload area, it provides information indicating how far the Offload area is located for the next location search.

For example, in FIG. 2, the terminal control apparatus for data offload (100 in FIG. 1) is 20 minutes depending on whether the terminal has a distance from the base stations G, I, D, and C. In step 3, the location information of the 10-minute interval is provided by the LBS (170 of FIG. 1), and the terminal belonging to the K base station transmits a message requesting to try again from the initial process after 30 minutes.

As another method of receiving the location information from the LBS (170 of FIG. 1) by the terminal control apparatus (100 of FIG. 1) for data offload, information about terminals belonging to the neighboring base stations of the base station requiring offloading may be obtained. Receiving is possible, and many similar methods can be applied.

The OSS (180 of FIG. 1) providing network status information provides status information such as traffic of an individual mobile communication base station unit, and the terminal control apparatus (100 of FIG. 1) for data offloading provides the corresponding information. Based on the determination of the traffic situation of the base station.

In order to use the periodic information, the traffic information is configured to predict through the process of comparing with the past information.

The order of traffic prediction or the case where the current traffic condition requires data offload is ordered according to the urgency, and the UEs are unconditionally switched to a wireless network or a similar emergency processing method is applied to an emergency area.

In FIG. 2, base stations I and G are areas where traffic is excessively concentrated, and D and C are areas where traffic concentration is expected.

The exact location of the actual terminal is collected for the candidate area scheduled to align the location of the actual terminal based on the base station and perform data offload.

Terminal 1, 2, 7, and 8 around the base stations are required to confirm the exact location information, as a result it was determined that terminal 1 will have a great effect in the offload area.

The collection of traffic information is provided by using a certain period, and accordingly, the traffic change is performed by considering the predetermined period or more.

Detailed location information of individual terminals is provided to the terminal control device (100 in FIG. 1) for data offload via the LBS system. In this case, a global positioning system (GPS) or a WPS ( LBS method such as Wi-Fi Positioning System) is applied to provide precise positioning.

The terminal may be directly triggered by the terminal control device (100 of FIG. 1) or the LBS for data offload to provide detailed location information.

The decision of whether to use the Global Positioning System (GPS) or the Wi-Fi Positioning System (WPS) can also be determined by the methods provided by the upper systems.

As a cumulative statistical result, the LBS method is applied at a corresponding base station location by setting a method having a superior precision among a GPS (GPS) or a Wi-Fi Positioning System (WPS). Use first.

Terminals entering the data offload area should basically transmit their information to the wireless network at the start of the service and if the previous policy is valid according to the policy provided (when time is valid or frequent failures are repeated). Etc.) may not provide information at the start of the service.

The method of notifying information to the wireless network by the terminal does not need to maintain real time in the case of data offload and transmits using a protocol of a general application development level.

On the contrary, the message provided by the terminal control device (100 in FIG. 1) for data offload uses a similar application protocol while simultaneously using a short message service (SMS) push service and an unstructured supplementary USUS. Use similar real-time protocols such as Services Data.

By providing such an asymmetric information transmission structure, it is possible to process the concentrated information from a large amount of terminals while maintaining the instantaneousness of the wireless network information.

In the case of a terminal located in the offload region for a long time, it is determined whether to switch the access network for offload based on the existing information.

Therefore, in case of a terminal that continuously fails, a scenario in which a terminal priority is selected low and only a terminal having a high priority is induced is applied.

FIG. 3 is a diagram illustrating a configuration of a terminal control apparatus for data offload of the present invention.

The terminal control apparatus for data offload of the present invention includes a location receiver 310, a traffic information receiver 320, an offload region determiner 330, a terminal position aligner 340, and a data policy establisher. It comprises 350.

The location receiving unit 310 receives the location of the plurality of first base stations providing the first wireless network service, the location of the plurality of second base stations providing the second wireless network service, and the location information of the plurality of terminals.

In one embodiment, the first wireless network may be a Wi-Fi wireless network, and the second wireless network may be a third generation network (3G) (WCDMA). In contrast, the second wireless network may be a Wi-Fi wireless network, and the second wireless network may be a third generation network (3G) (WCDMA).

The location receiving unit 310 receives the location information of the base station and the location information of the terminal connected to the base station from a global positioning system (GPS) or a Wi-Fi positioning system (WPS).

It is not necessary to adopt the same LBS scheme for each base station cell, and a scheme that provides various location information precisions can be selectively selected.

The traffic information receiver 320 receives a data traffic amount of the first base station or the second base station.

The terminal control apparatus for data offload of the present invention receives traffic information of each base station from an operations support system (OSS).

The offload zone determination unit 330 is configured to switch the first base station or the second base station from the first wireless network service to the second wireless network service or the second wireless network based on the amount of data traffic received from the OSS. It is determined whether a data offload region is required to switch from a service to the first wireless network service, and the data offload region is ranked.

That is, as shown in FIG. 2, the base stations I and G may be determined to be data offload regions in which the traffic is excessively concentrated, and the base stations I and G may be determined as the concentration of traffic is lower than that of the base stations I and G. G is ranked first, and base stations D and C are second, and the remaining base stations are also ranked according to the traffic information received from the OSS.

The terminal position aligner 340 calculates the separation distance between the base station and the terminals whose rank of the data offload region is higher than the reference rank.

In FIG. 2, terminals 1, 2, 7, and 8 may have a short distance from the base stations I and G, and a short distance between the terminal 1 and a long distance between the terminal 3 and the terminal 4 may be the longest.

As the separation distance between the terminals becomes shorter, the data policy establishment unit 350 switches the position information receiving period of the terminal, the receiving period of the data traffic amount, and the switching from the first wireless network service to the second wireless network service or the second wireless. The data transmission period including the switching information from the network service to the first wireless network service is shortened.

The terminal control apparatus for data offload of the present invention can minimize the load of the terminal control apparatus by adjusting the access period of the terminal by using a distance between the terminal and the base station in the data offload region, It has the effect of reducing the resource consumption of.

FIG. 4 is a flowchart of a terminal controlling apparatus for data offload of the present invention in which a terminal manages an automatic connection to a wireless router (AP) in a wi-fi wireless network.

FIG. 4 is a diagram illustrating an example in which a terminal is automatically connected to an AP when a first wireless network or a second wireless network controlled by a terminal control device for data offload of the present invention is a wi-fi wireless network. It is a schematic of the connection process.

When the terminal control device for data offload of the present invention has incorrect location information of the terminal and attempts to access a desired access point (AP), it minimizes repetitive access attempt failure and provides efficient update information to other terminals. It shows a method for providing.

When the terminal control apparatus for data offload recognizes a change in the position of the terminal (S410), the terminal control apparatus for data offload may be connected to a location center of an area where the wireless terminal is present and an AP accessible. In consideration of the distance (R), as shown in the embodiment shown in S420, a policy of different access attempts is established according to each case and transmitted to the terminal.

The position of the radio terminal received by the terminal control apparatus for data offload may be implemented in the form of a circle located within a certain radius, and R is from the center point P of the circle where the terminal is likely to exist. The distance to the AP that you want to access.

S420 illustrates an embodiment in which the terminal control apparatus for data offload transmits a repetition period differently to the terminal in consideration of R, Wi-Fi AP coverage D, and user position error T.

Here, the user position error T is an error that may occur due to the movement of the user in the terminal's current estimated position of the terminal for data offload.

(1) Distance between position center point (P) of wireless terminal and accessible AP (R)> Wi-Fi AP coverage D plus user position error (T) (R> D + T (Type1 in FIG. 5)

That is, there is no probability that the wireless terminal exists in the Wi-Fi AP coverage D.

(2) Wi-Fi AP when the distance between the position center point (P) of the wireless terminal and the accessible AP (R) <Wi-Fi AP coverage D plus the user position error (T) (R <D + T) There is a possibility that the terminal exists within the coverage (D) of, but the terminal location center point (P) does not exist within D (PT in AP) (Type2 of FIG. 5)

That is, the circle representing the location radius of the wireless terminal overlaps with the coverage D of the wifi AP, but the terminal location center point P does not exist within D, and the terminal is closer to the AP than the case of (1).

(3) When the location center point P of the terminal exists in the wifi AP coverage D (P in AP) (Type3 of FIG. 5),

(4) When the entire circle indicating the location radius of the terminal exists within the Wifi AP coverage (P + T in AP) (Type 4 of FIG. 5), etc., the number of reconnection attempts is more likely to belong to the coverage D ( The method of increasing N) is applied.

That is, as proceeding from (1)-> (4), the terminal is closer to the WiFi AP, and is determined to have a high priority, so that the terminal is connected by the data policy establishment unit 350 of the terminal control apparatus for data offload. Develop a policy to increase the number of attempts.

The terminal that has received the information including the number of access attempts from the terminal control apparatus for data offload determines whether the AP that it attempts to access is the same AP that is the basis for determining the number of attempts in S420 (S430). .

The terminal repeats the access attempt to the corresponding AP based on the number of reconnection attempts determined in S420 (S440).

When the terminal fails to access the corresponding AP, the terminal control apparatus for data offload increases the size of a cell that is an AP coverage (S470) or decreases the size of a cell that is an AP coverage (S460).

The terminal control apparatus for data offload takes into account the state of use of the wireless terminal, changes the traffic pattern, uses a specific application, or defines a certain period according to a separation distance or a specific rule through the collected information. It is determined how often to re-run the series of connection attempt procedure described above (S480).

FIG. 5 is an embodiment of a method of variably applying Wi-Fi access coverage based on whether a user successfully connects, and assumes that an attempt to reconnect to an AP is performed based on the set number of connection attempts in S420 of FIG. 4. .

When the repeated access attempt period is set according to the location of each terminal by the data offload system, the terminal proceeds with the actual access attempt and classifies the same WiFi AP and notifies the offload system of the result when the connection fails, thereby increasing the AP access range. Or reduce it.

The number of reconnection attempts according to the location of each terminal may be set higher as the terminal approaches the Wifi AP.

In the case where the coverage D of the Wifi AP of FIG. 5 is greater than the location radius of the terminal, an embodiment according to the distance between the terminal and the AP is illustrated in detail.

However, when the coverage D of the Wifi AP is smaller than the location radius of the terminal (550, 560, 570), even if the location radius of the terminal is present in the coverage D of the Wifi AP, it is not considered in the present invention as an exception.

Type 1 510 of FIG. 5 is a case where (1) R> D + T in S420 of FIG. 4, and the existence probability of the terminal does not exist at all in the coverage D of the Wifi AP.

However, exceptionally, even though the terminal succeeds in accessing the AP, the coverage indicating the accessible range of the AP is increased based on the distance between the center point P of the terminal and the AP.

Type 2 (520) of FIG. 5 is (2) PT in AP in S420 of FIG. The case exists outside the coverage D of the Wifi AP.

When the terminal fails to access the AP based on the number of reconnection attempts, the terminal control apparatus for data offloading reduces the coverage D of the Wifi AP.

Type3 530 of FIG. 5 is (3) P in AP in S420 of FIG. 4, where the center point P of a circle, which is an area where a terminal may exist, is within the coverage D of the Wifi AP.

When the terminal fails to access the AP by the number of reconnection attempts established by the terminal control apparatus for data offload, the terminal control apparatus for data offload reduces the coverage D of the Wifi AP.

Type 4 540 of FIG. 5 is a case of (4) P + T in AP in S420 of FIG. 4, in which the entire circle, which is an area where a terminal may exist, is within the coverage D of the Wifi AP.

When the terminal fails to access the AP by the number of reconnection attempts established by the terminal control apparatus for data offload, the terminal control apparatus for data offload reduces the coverage D of the Wifi AP.
