Furthermore, the heterogeneous network-based data concurrent transmission service system according to the present invention includes an external device 500 that receives combined data from the management device 400 and a policy management device 600 that provides a network selection policy .

The heterogeneous network-based data concurrent transmission service according to the present invention is a service for simultaneously transmitting data between a terminal device 100 and an external device 500 by dividing data and transmitting data using a plurality of heterogeneous networks (e.g., a 3G network and a WiFi network) / Receive < / RTI >

Accordingly, in the present invention, the session is divided in the management apparatus 400 in order to realize simultaneous link transmission through a plurality of heterogeneous networks for one session. At this time, since the terminal device 100 is connected to each of a plurality of heterogeneous networks (for example, a 3G network and a WiFi network), the management apparatus 400 can access a plurality of heterogeneous networks (e.g., a 3G network and a WiFi network) It is necessary to recognize that each terminal device 100 is a link of each terminal device 100 and manage it as one terminal device 100, that is, a single entity. For this purpose, it is inevitably required to allocate / manage additional virtual network connection information (e.g., virtual IP) for the coexistent transmission service corresponding to the terminal device 100. [

The external device 500 refers to a server device that transmits and receives data to and from the terminal device 100 through the management device 400. The external device 500 may transmit and receive data to and from the terminal device 100 through the management device 400, Portal service, and content providing service.

[

Meanwhile, the heterogeneous networks may be various access networks including WCDMA, CDMA, WiBro, WLAN (WiFi) and LTE (Long Term Evolution), for example. However, in the present embodiment, (Hereinafter referred to as a " WiFi network ") which refers to a first network (hereinafter referred to as a 3G network) and a second wireless network (WiFi)

Accordingly, the first network device 200 refers to a 3G network, that is, a Gateway GPRS Support Node (GGSN) for operating a wireless packet service network. In addition, the second network device 300 includes a WiFi network, And an access point (AP) for operating a short-range wireless network.

Also, the terminal device 100 and the management device 400 may be a transmission device according to a service flow, i.e., a subject that transmits data using a simultaneous data transmission service, that is, according to an uplink process and a downlink process , Or a receiving device. For convenience of description, the present embodiment assumes that the terminal device 100 is located in a heterogeneous network environment and performs data transmission and reception, and assumes a management device 400 that provides a simultaneous data transmission service to the terminal device 100 .

First, in order to use the data concurrent transmission service in the heterogeneous network environment, the connection information acquisition procedure between the terminal device 100 and the management device 400 must be preceded.

In this regard, the terminal device 100 performs location registration with respect to the 3G network, and transmits its first network connection information (e.g., 3G IP) according to the existing connection information allocation scheme from the first network device 200 And requests the first network device 200 for the connection information of the management apparatus 400 for access to the 3G network. In addition, the terminal device 100 performs connection to the WiFi network and receives its second network connection information (e.g., WiFi IP) from the second network device 300 according to an existing connection information allocation scheme .

The first network device 200 transmits access information for the 3G network connection to the management apparatus 400 from the address assignment apparatus 700, for example, DNS server in response to the connection information request transmitted from the terminal apparatus 100, Acquires the connection information of the management apparatus 400 for 3G network access as a private IP, and transfers the acquired information to the terminal apparatus 100. Accordingly, the terminal device 100 recognizes the connection information (e.g., management device 3G IP) of the management apparatus 400 for 3G network connection that can access the management apparatus 400 via the first network, that is, the 3G network.

Further, the terminal device 100 further requests the first network device 200 to connect the connection information of the management device 400 for connection to the WiFi network.

Accordingly, the first network device 200 can access the WiFi network connection information for the management apparatus 400, that is, the access information of the 3G network connection management apparatus 400, from the address assigning apparatus 700, Acquires the connection information of the management device 400 for WiFi network connection as a public IP to be mapped and transmits the acquired connection information to the terminal device 100. Accordingly, the terminal device 100 recognizes the connection information (e.g., management device WiFi IP) of the management device 400 for connection to the WiFi network which can be connected to the management device 400 via the second network, that is, the WiFi network.

On the other hand, when the terminal device 100 requests the first network device 200 as described above, the access information (e.g., the management device 3G IP) of the management device 400 for access to the management server 400 Acquiring / recognizing the connection information (e.g., the management device WiFi IP) of the management device 400 for accessing the WiFi network is only an embodiment, and the access information of the management device 400 for access to the 3G network in the terminal device 100 Acquiring / recognizing the connection information (e.g., the management device 3G IP) and the connection information (e.g., management device WiFi IP) of the management device 400 for connection to the WiFi network will be possible through various other procedures.

Next, when the connection information acquisition procedure for the management apparatus 400 is completed, a service registration procedure between the terminal apparatus 100 and the management apparatus 400 should be performed.

In this regard, the terminal device 100 accesses the management apparatus 400 via the respective networks based on the acquired 3G network connection access information and WiFi network connection access information, and requests service registration.

For example, the terminal apparatus 100 is connected to the management apparatus 400 via the first network, that is, the 3G network, based on the obtained connection information (for example, the management apparatus 3G IP) of the management apparatus 400 for access to a public network And transmits a binding update message (Binding Update) to request registration of the service for the terminal device 100 itself. Accordingly, the management apparatus 400 receives the additional information included in the service registration request, such as device identification information (e.g., IMSI), first network connection information (e.g., 3G IP) (Binding Update Ack) to the terminal device 100 by checking service type information (e.g., 3G) and service classification information (Initial, Update, and Remove) By returning, the service registration procedure through the 3G network can be performed.

The terminal device 100 accesses the management device 400 via the second network, that is, the WiFi network, based on the acquired connection information (e.g., management device WiFi IP) of the management device 400, and transmits a binding update message ), Thereby requesting service registration of the terminal device 100 itself. Accordingly, the management apparatus 400 transmits the additional information included in the service registration request, such as device identification information (e.g., IMSI), second network connection information (e.g., WiFi IP) (Binding Update Ack) to the terminal device 100 by confirming the type information (e.g., WiFi) and the service classification information (Initial, Update, and Remove) , The service registration procedure through the WiFi network can be performed.

At this time, the terminal device 100 allocates and holds separate virtual network access information (e.g., virtual IP) for the simultaneous network-based data concurrent transfer service according to the present invention, and the management device 400 can manage .

Accordingly, the terminal apparatus 100 can receive and retain the virtual network connection information (e.g., virtual IP) allocated from the management apparatus 400 in the service registration procedure through the 3G network or the WiFi network as described above, or (E.g., 3GN, IMSI, IMEI, etc.) based on the stored device identification information (e.g., MDN, IMSI, IMEI, etc.) And may be used / retained as network connection information.

In addition, the management apparatus 400 can manage subscriber-specific table information, for example, terminal apparatuses registered for each subscriber, based on the supplementary information included in the service registration request of the terminal apparatus 100 received via the 3G network and the WiFi network, (E.g., 3G IP and WiFi IP), virtual network connection information (e.g., virtual IP), service classification information (Initial, etc.) mapped based on the device identification information (e.g., IMSI) Update, Remove), and the like.

The management apparatus 400 includes a network selection policy for traffic distribution in a heterogeneous network environment, for example, source IP, source port, destination IP, destination port, protocol (UDP, TCP, And the traffic distribution rate per network can be additionally managed to the subscriber-specific table information.

Herein, the management apparatus 400 can register and manage the network selection policy provided from the policy management apparatus 600 when registering the service for the terminal apparatus 100. In addition, in order to efficiently provide the data concurrent transfer service, The network selection policy through detection can be changed in real time.

That is, when registering the service for the terminal device 100, the management device 400 receives the network selection policy provided from the policy management device 600 from the terminal device 100, registers the management information in the subscriber-specific table information, The network selection policy directly transmitted from the device 600 and the network selection policy transmitted through the terminal device 100 when registering the service for the terminal device 100 can be combined and managed.

In the case of changing the network selection policy through the network status detection, for example, when using the data concurrent service between the terminal device 100 and the management device 400, it is possible to check the throughput per second The management apparatus 400 recognizing the status report based on the link status detection and the network disconnection detection through the status signal reception having the predetermined period performs the traffic distribution rate change according to the 3G network and the WiFi network, If necessary, is transmitted to the policy management apparatus 600 so as to be utilized in the new network selection policy.

As described above, when the procedure for registering the service between the terminal device 100 and the management device 400 is completed, the data transmission / reception between the terminal device 100 and the external device 500 can be performed using a heterogeneous network, that is, a 3G network and a WiFi A mobile communication service over a network will be initiated. The following description will be made on the basis of an uplink procedure in which the terminal device 100 transmits data to the management device 400. [

The terminal device 100 divides the transmission target data into partial data to use the simultaneous transmission service.

That is, the terminal device 100 divides data to be transmitted in correspondence to the number of networks for simultaneous transmission of data using a heterogeneous network environment, that is, a 3G network and a WiFi network. According to the changed network-specific traffic distribution rate received from the management apparatus 400 according to the network selection policy transmitted or the real-time network status detection.

In other words, the terminal device 100 confirms a first transmission rate for data transmission to the first network device 200 included in the network selection policy and a second transmission rate for data transmission to the second network device 300 Selects the first partial data to be transmitted to the first network device 200 among the divided partial data based on the confirmed transmission ratio and selects the second partial data to be transmitted to the second network device 300 among the remaining partial data .

Accordingly, the terminal device 100 performs the above-described data division process based on the network selection policy and the traffic distribution rate for each network that is changed in real time, so that the relative use ratio of the 3G network and the WiFi network is changed to 10% 90% of WiFi network, 90% of 3G network and 10% of WiFi network, 50% of 3G network and 50% of WiFi network, 0% of 3G network and 100% of WiFi network and 100% of 3G network and 0% of WiFi network have.

Then, the terminal device 100 includes virtual network connection information (e.g., virtual IP) in the first partial data and virtual network connection information (e.g., virtual IP) in the second partial data.

Of course, the terminal device 100 may transmit first network access information (for example, 3G IP) corresponding to the first network, as well as virtual network connection information (e.g., virtual IP) The connection information of the corresponding management apparatus 400, that is, the connection information (e.g., management apparatus 3G IP) of the management apparatus 400 for access to the 3G network and the connection information of the external apparatus 500 corresponding to the final destination .

In addition to the virtual network connection information (for example, virtual IP), the terminal device 100 transmits its second network connection information (e.g., WiFi IP) corresponding to the second network to the second partial data, (For example, management device WiFi IP) of the management device 400 corresponding to the WiFi network, and connection information of the external device 500 corresponding to the final destination .

Thereafter, the terminal device 100 transmits the first partial data to the first network device 200 located in the 3G network, and the first network device 200 transmits the first partial data to the management device 400 ). Then, the terminal device 100 transmits the second partial data to the second network device 300 located in the WiFi network, and the second network device 300 transmits the second partial data to the management device 400 as the receiving device Lt; / RTI >

The first partial data divided in the terminal device 100 is transmitted to the management device 400 via the 3G network and the divided second partial data is transmitted to the management device 400 via the WiFi network.

The management device 400 receives the first partial data from the first network device 200 and receives the second partial data from the second network device 300 and includes the received first partial data and the second partial data The first partial data and the second partial data according to the specific virtual network connection information are combined based on the virtual network connection information and the data is generated to restore the transmission target data to be transmitted from the terminal device 100. [

That is, the management apparatus 400 generates first partial data having the same virtual network connection information (e.g., virtual IP) based on the virtual network connection information (e.g., virtual IP) included in the received partial data, The original transfer target data can be generated by recognizing the data and combining / combining them according to the order information included in the corresponding partial data.

Then, the management apparatus 400 may use the connection information of the external device corresponding to the final destination recognized through the partial data of at least one of the first partial data and the second partial data, And transmits the data to be transmitted.

The first partial data and the second partial data divided in the terminal device 100 are combined by the management device 400 in the course of passing through the management device 400 via the heterogeneous network (3G and WiFi network) And the restored data to be transmitted is transmitted as one piece of data to the external device 500 which is the final destination.

In the following description, a description will be given of a data concurrent transfer service procedure between the terminal device 100 and the management device 400 based on the downlink procedure in which the management device 400 transmits data to the terminal device 100 .

For data requested to be transmitted from the external device 500 to the terminal device 100, the management device 400 divides the data to be transmitted into partial data to use the simultaneous transmission service.

That is, the management apparatus 400 divides the data to be transmitted in correspondence with the number of the network in order to simultaneously transmit data using the heterogeneous network environment, that is, the 3G network and the WiFi network. The division process is transmitted from the policy management apparatus 600 Based on the network selection policy or the real-time network state detection.
