Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a diagram illustrating a heterogeneous network-based simultaneous data transmission service system according to a preferred embodiment of the present invention.

As shown in FIG. 1, a heterogeneous network-based data simultaneous transmission service system according to the present invention includes a management apparatus 400 for supporting a simultaneous transmission service in which data to be transmitted is divided into two or more partial data and transmitted through two or more networks. And at least one transmitter 100 connected to the management device 400 to use a simultaneous transmission service.

Here, two or more networks, i.e., heterogeneous networks, may include WCDMA, CDMA, WiBro, WLAN (WiFi) and Long Term Evolution (LTE).

In the present invention, for convenience of explanation, a first network (hereinafter referred to as a "3G network"), which refers to a wireless packet service network (WCDMA) among two or more networks, and a second network 2 network (hereinafter referred to as "WiFi network"). Accordingly, the first network device 200 refers to a gateway GPRS support node (GGSN) device for operating a 3G network, that is, a wireless packet service network, and the second network device 300 is a WiFi network, It refers to an access point (AP) for operating a local area wireless network.

In addition, the heterogeneous network-based data concurrent transmission service system according to the present invention includes an external device 500 that receives data combined / restored according to a simultaneous transmission service from the management device 400, and a policy management (600). ≪ / RTI >

Here, the external device 500 refers to a server device that performs data transmission and reception with the transmission device 100 through the management device 400, to the transmission device 100 through data transmission and reception through the management device 400. For example, various services such as a portal service and a content providing service may be provided.

In addition, the policy management apparatus 600 may include, for example, a transmission apparatus 100 and a management apparatus according to various network parameters and network state variations on heterogeneous networks including subscriber preferences, subscriber types, subscription plans, types of service target applications, and the like. The network selection policy is determined based on the network state information received from 400 and provided to the transmitting apparatus 100 and the managing apparatus 400.

Accordingly, the heterogeneous network-based data transmission service according to the present invention divides one piece of data between the transmission device 100 and the management device 400 for data transmission and reception between the transmission device 100 and the external device 500. The divided partial data is transmitted using a plurality of heterogeneous networks (eg, 3G and WiFi), and a simultaneous transmission service for combining the received partial data and restoring the original data is implemented.

In order to use the simultaneous transmission service, the transmitting apparatus 100 must maintain a state of being connected to two or more networks (eg, 3G and WiFi) to be used in the simultaneous transmission service.

Here, in the case of the WiFi network in general, the connection change such as changing the connection from the AP currently connected to another AP due to the movement of the transmitting device 100, or changing the connection to another AP due to the traffic overload of the currently connected AP. Has a frequent network environment. In a WiFi network environment, when a transmitter 100 accesses an AP, a password is set for network security, and a user of the transmitter 100 inputs a password to authenticate the access and then allow the connection.

Therefore, when the transmitting device 100 using the simultaneous transmission service uses the WiFi network, a cumbersome situation in which a user inputs a password, that is, information for access authentication, may occur every time the AP is connected.

Accordingly, according to the present invention, the transmitter 100 will in turn connect to two or more networks to be used in the simultaneous transmission service. At this time, it is preferable that the transmitter 100 first connects to the first network, that is, the 3G network, of two or more networks.

In addition, the transmitter 100 searches for at least one network device (eg, an AP) located in the second network to access a specific network, that is, a second network corresponding to WiFi, from among two or more networks.

The transmitter 100 is connected to the access information providing apparatus 700 via a network other than a specific network (for example, WiFi), for example, a 3G network that is connected first and relatively secure among two or more networks. The terminal may request access information corresponding to the found at least one network device (eg, an AP).

When the connection information providing apparatus 700 receives a connection information request corresponding to at least one network device (for example, an AP) from the transmitter 100, at least one network device (for example, an AP) according to the connection information request. To provide the connection information of the transmitter 100.

In this regard, the transmission apparatus 100 performs a connection procedure for a specific second network apparatus 300 among at least one searched second network apparatus using the access information provided from the access information providing apparatus 700. You will be connected to a WiFi network.

In other words, the transmitting apparatus 100 requests the connection authentication information by providing the connection authentication information (for example, a password) included in the connection information obtained as described above to the second network device 300, and thereby the second network device. The device 300 determines whether to allow access to the transmitting device 100 by determining whether or not it is the same by comparing with pre-owned connection authentication information (eg, a password), and transmits the result (for example, access permission) to the transmitting device. By returning to 100, a connection procedure between the transmitting device 100 and the second network device 300 is performed.

Accordingly, the transmitter 100 accesses the second network, that is, the WiFi network, by performing an access procedure and accessing the second network apparatus 300.

As described above, according to the present invention, the transmitter 100 obtains access information about a network device (AP) to which it can access through a 3G network secured, and automatically connects to the network device (AP) using the WiFi. By connecting to the network, it is possible to prevent the user from having to manually enter access authentication information (eg, a password) for security.

Thereafter, the transmitter 100 accesses the management apparatus 400 through each of at least two connected networks (for example, 3G and WiFi) to perform service registration for a simultaneous transmission service, and then the transmitter 100 and For data transmission and reception between the external device 500, one data is divided between the transmitting device 100 and the management device 400, and the divided partial data are transmitted using a plurality of heterogeneous networks (for example, 3G and WiFi). It will then run a concurrent transmission service that combines the received partial data and restores the original data.

Meanwhile, while the transmitting device 100 uses the simultaneous transmission service through two or more networks (eg, 3G and WiFi), an existing AP handover occurs due to factors such as movement of the transmitting device 100 or traffic overload. According to an algorithm, a case may occur in which the second network apparatus 300 in the current connection state is connected to another second network apparatus 300.

In this case, too, the transmitter 100 accesses the new second network apparatus through the network apparatus search, the request for the access information of the found network apparatus, and the access procedure using the obtained access information as described above. You will stay connected to the WiFi network.

Alternatively, while the device search unit 120 uses the simultaneous transmission service through two or more networks (eg, 3G and WiFi) in the simultaneous transmission service unit 150, the device search unit 120 may move or access the connected network device. When a connection movement occurs from a currently connected second network device of a specific second network (for example, WiFi) to another second network device due to a traffic overload, etc., a specific second network (for example, At least one second network device (eg, an AP) located in the WiFi may be searched for.

In this case, the method of searching for at least one accessible network device located in a specific network (eg, WiFi) by the device searching unit 120 will correspond to a method of searching for an existing WiFi AP, and thus a detailed description thereof will be omitted. .

The connection information acquisition unit 130 obtains connection information corresponding to the at least one network device searched by the device search unit 120 through a network other than the specific network among two or more networks.

In more detail, before transmitting to the WiFi network, the transmitter 100 may first be connected to at least one network (eg, 3G) of two or more networks to be used in a simultaneous transmission service.

Accordingly, the access information acquisition unit 130 connects to the access information providing apparatus 700 that manages the access information through a network having the highest security in the remaining network except for a specific network among two or more networks, and the searched at least one network. The connection information corresponding to the device may be requested.

That is, the access information acquisition unit 130 recognizes a network having the highest security among remaining networks except for a specific second network (for example, WiFi) among two or more networks. At this time, the access information acquisition unit 130, it is preferable to recognize that the first network that is secured, that is, the 3G network as the highest security network.

The connection procedure between the transmitting device 100 and the second network device 300 is performed by determining whether to allow the connection and returning the result (for example, allowing connection) to the connection controller 140.

Accordingly, when a result of allowing the connection is returned from the second network device 300, the connection controller 140 connects to the second network device 300 to connect to the second network, that is, the WiFi network.

As such, when the transmitter 100 is connected to each of two or more networks (eg, 3G, WiFi) to be used in the simultaneous transmission service, the simultaneous transmission service unit 150 converts the transmission target data into two or more partial data as described above. It is possible to divide and transmit the data through two or more networks (eg, 3G, WiFi), and to combine / create the partial data received correspondingly into one data.
