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

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

As shown in FIG. 1, the multi-network-based 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 terminal device 100 connected to the management device 400 to use a simultaneous transmission service.

Here, two or more networks, that is, multiple networks, may include WCDMA, CDMA, WiBro, WLAN (WiFi), Long Term Evolution (LTE), and the like.

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 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.

Furthermore, the multi-network based simultaneous transmission service system according to the present invention, the external device 500 for receiving the combined / restored data according to the simultaneous transmission service from the management device 400 and the policy management device for providing a network selection policy (Not shown).

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 is connected to the terminal device 100 through data transmission / For example, various services such as a portal service and a content providing service can be provided.

Accordingly, the multi-network-based simultaneous transmission service according to the present invention divides and divides one data between the terminal device 100 and the management device 400 for data transmission and reception between the terminal device 100 and the external device 500. The data is transmitted using a plurality of multiple networks (eg, 3G and WiFi), and the received data is combined to implement a simultaneous transmission service to restore the original data.

At this time, the terminal device 100 and the management device 400 may be devices on the transmission side according to the uplink process and the downlink process, depending on the subject of data transmission using the service flow, that is, the data transmission service And may be a device on the receiving side. In the present embodiment, for convenience of description, a management apparatus 400 as a transmission apparatus for providing data simultaneous transmission service to a terminal apparatus 100 is provided and described in a multiple network environment based on a downlink process. Assuming that the terminal device 100 as a receiving device for performing data transmission and reception with 400 will be described.

Therefore, since the simultaneous transmission service provided by the present invention simultaneously transmits the partial data divided from one data using a plurality of multiple networks (for example, 3G and WiFi), the plurality of multiple transmissions are performed on the terminal apparatus 100 side. It is very important to restore all the partial data received through the network (eg 3G and WiFi) without loss / loss and combine them according to the partitioning order.

However, there is a difference between the latency of each network because the network quality (throughput, delay, loss, etc.) between each network is different from each other and the network state of each network is variable in real time. Therefore, even though each piece of data is simultaneously transmitted using a plurality of multiple networks (eg, 3G and WiFi), the terminal device 100 may not actually transmit each network (eg, 3G and WiFi) due to differences in transmission latency between networks. There is a difference in the point of reception of the partial data received through.

Therefore, in consideration of the fact that the reception time of the partial data received through each network is different due to the transmission delay of each network, the receiving side rearranges the partial data received through each network in the receiving buffer in order and advances. If the partial data of the sequence is not received, it waits for the unreceived partial data to be received.

Therefore, on the receiving side, the more partial data packets arrive out of order in each network, the longer the waiting time for correct partial data packet rearrangement and the more reordering operations, which is not good for simultaneous transmission performance quality. Will be affected.

Therefore, in the present invention, in the environment for providing simultaneous transmission service, the independent network transmission order information for the transmission order for each network is inserted and received, as well as the transmission order information for the entire order of transmission without division of multiple networks into each partial data. The network calculates the reordering rate for each network based on the network transmission order information of the partial data received for each network, and the sender transmits the partial data for transmission to the network having low network quality based on the reordering rate for each network. By using the redundant transmission, we propose a configuration that improves the transmission performance and quality of the simultaneous transmission service.

For convenience of description, referring to the downlink, the management apparatus 400 as the transmitting apparatus, that is, the multiple network-based simultaneous transmitting apparatus, transmits data to be transmitted from the external apparatus 500 to the terminal apparatus 100. When received, it is divided into partial data.

At this time, it is preferable that the management apparatus 400 combines the partial data divided from the transmission target data and adds / inserts the division order information to each partial data so that the original transmission target data can be restored.

Then, the management apparatus 400 selects each divided partial data for each connection network based on the predetermined data transmission ratio for each connection network.

That is, when the management apparatus 400 receives the transmission target data to be transmitted from the external apparatus 500 to the terminal apparatus 100, the management apparatus 400 divides the transmission target data into partial data and transmits the data transmission rate (for example, WiFi and 3G) That is, a first transmission rate for data transmission to the first network device 200 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 partial data and selects the second partial data to be transmitted to the second network device 300 among the remaining partial data.

Then, the management apparatus 400 transmits each partial data selected for each access network (e.g., WiFi and 3G) through each access network (e.g., WiFi and 3G) The second network device 300 transmits the first partial data transmitted from the management device 400 to the terminal device 100 and the second network device 300 transmits the second partial data transmitted from the management device 400 to the terminal device 100 .

In this case, the management apparatus 400 assigns / inserts transmission order information for the entire order of transmission without distinction of network types to each partial data transmitted through the access network (eg, WiFi and 3G).

For example, as shown in FIG. 7, the management apparatus 400 assigns / inserts transmission order information 1, 2, and 3 to first, second, and third partial data transmitted to a second network, that is, a WiFi network. Assign / insert transmission sequence information 4,5 to the fourth and fifth partial data transmitted to one network, that is, 3G network, and assign / insert transmission sequence information 6 to the sixth partial data transmitted to the WiFi network, and to the 3G network. Transmission order information 7 can be assigned / inserted to the seventh partial data to be transmitted, and transmission order information 8 can be assigned / inserted to the eighth partial data transmitted to the WiFi network.

At this time, the transmission order information and the division order information described above to be given / inserted to each partial data may be the same or different from each other.

Furthermore, the management apparatus 400 inserts network transmission order information relating to an order of transmitting the specific partial data through the specific access network, into the specific partial data selected corresponding to the specific access network.

In this case, the specific access network may be one access network selected from two or more access networks, or may mean each of two or more access networks.

That is, the management apparatus 400 may insert independent network transmission order information of the transmission order for each of the two or more access networks into each partial data.

For example, as illustrated in FIG. 7, the management apparatus 400 may respectively correspond to partial data of transmission sequence information 1, 2, 3, 6, and 8 selected to be transmitted to the WiFi network, corresponding to each of the 3G and WiFi networks. Network transmission order information 1, 2, 3, 4, and 5 can be assigned / inserted for the order of transmission through the WiFi network, and each of the partial data of the transmission order information 4, 5, and 7 selected for transmission to the 3G network is added. Network transmission order information 1, 2, and 3 can be assigned / inserted for the order of transmission through the 3G network.

Referring to FIG. 7, referring to the partial data of the transmission order information 1 to be transmitted via WiFi as an example, the information as the transmission order information according to the order transmitted from the management device 400 in the area ⓐ without distinguishing between 3G and WiFi networks. 1 is included, and the area ⓑ may include information 1 as network transmission order information according to the order transmitted from the management apparatus 400 via WiFi.

Accordingly, the terminal device 100 can restore the transmission object data by combining the partial data received through two or more networks based on the division order information.

More specifically, the terminal device 100 receives the first partial data from the first network device 200 via two or more access networks (e.g., WiFi, 3G) and transmits the second partial data to the second network device 200 (300).

Accordingly, the terminal device 100 recognizes partial data having the same identification information (eg, virtual IP) indicating that the data is divided from one data based on identification information (eg, virtual IP) included in the received partial data. And, they can be rearranged to the receiving buffer based on the transmission order information included in the corresponding partial data.

At this time, the terminal device 100 corresponds to each piece of data received through two or more access networks (eg, 3G, WiFi), and when the unbuffered part data is confirmed as a result of the reordering of the reception buffer, the part data that is not received is not received. After that, the partial data of the transmission sequence information is waited without being delivered to a higher layer (for example, an application using a simultaneous transmission service) for a preset waiting time. Subsequently, the partial data of the transmission order information is transferred to a higher layer, so that a retransmission request such as Dup Ack related to the unreceived partial data may be generated, thereby retransmitting a request for the lost unreceived partial data, for example, a duplicate arc. (Dup Ack) can be provided to the management apparatus 400 of a transmitting side.

Through this process, the terminal device 100 may restore the transmission target data by combining the rearranged partial data based on the split order information included in the corresponding partial data.

At this time, the terminal device 100 confirms the partial data received through a specific access network of two or more access networks (eg, 3G, WiFi). Here, the specific access network may be one access network selected from two or more access networks as described above, or may mean each of two or more access networks.

In an embodiment of the present invention, a specific access network will be described as meaning each of two or more access networks (eg, 3G, WiFi).

In addition, the terminal device 100 checks the partial data received through each specific access network, that is, the access network (eg, 3G, WiFi), and then is transmitted from each of the checked partial data through the access network (eg, 3G, WiFi). Check the network transmission sequence information related to the sequence.

Accordingly, the terminal device 100 is associated with each of the access networks (eg, 3G, WiFi) based on the network transmission order information of the partial data received through a specific access network, that is, each access network (eg, 3G, WiFi). The reordering rate can be calculated.

For example, referring to FIG. 7, the partial data of the transmission order information 4, 5, and 7 transmitted through the 3G from the management device 400 is transmitted to the terminal device 100 as shown in FIG. 7. Partial data of transmission order information 1,2,3,6,8 received in partial data order of 5,7 and transmitted from the management device 400 via WiFi is transmitted to terminal device 100 in order of transmission information 1,6 Assume that the data is received in the order of partial data of, 2,3,8.

Accordingly, the terminal device 100 receives each of 3G and WiFi separately from rearrangement based on the transmission order information in response to the partial data received through two or more access networks (eg, 3G and WiFi) as described above. The partial data. Accordingly, the terminal device 100 may check the partial data of the transmission order information 4, 5, 7 received through 3G, and transmit the partial data of the transmission order information 1, 6, 2, 3, 8 received via WiFi. You can check it.

The terminal device 100 confirms the network transmission order information from the partial data confirmed for each of 3G and WiFi.

For example, the terminal device 100 may transmit the network transmission order information 1, 4, 2, related to the order of transmission via WiFi from the partial data of the transmission order information 1, 6, 2, 3, 8 received via WiFi. 3,5 can be confirmed.

Of course, the terminal device 100 may check the network transmission order information 1,2,3 related to the order of transmission through WiFi from the partial data of the transmission order information 4,5,7 received through 3G.

Accordingly, the terminal device 100 may calculate the reordering rate in relation to WiFi on the basis of the network transmission order information 1, 4, 2, 3, 5 of the partial data received via WiFi, and the received portion via 3G. The reordering rate can be calculated in relation to 3G based on network transmission order information 1,2,3 of data.

Preferably, the terminal apparatus 100 uses the number of specific partial networks corresponding to the specific access network and the number of partial data requiring rearrangement according to the network transmission order information within the specific partial data. The reordering rate can be calculated.

For example, the terminal device 100 includes the number of partial data of transmission order information 1, 6, 2, 3 and 8 received through WiFi, and the partial data of transmission order information 1, 6, 2, 3 and 8. Checks the number 2 of partial data (partial data of network transmission order information 2 and 3) requiring reordering according to the network transmission order information 1, 4, 2, 3, and 5, and the rearrangement rate with respect to WiFi. (= 40%) can be calculated.

On the other hand, the terminal device 100, the network transmission order information 1, 2, 3 in the partial data number 3, the transmission order information 4, 5, 7 of the transmission order information 4, 5, 7 received through 3G According to the present invention, the number of partial data (none) requiring realignment can be checked, and the reordering rate 0/3 (= 0%) can be calculated in relation to 3G.

In addition, the terminal device 100 provides the management apparatus 400 with the reordering rate calculated in relation to each of a specific access network, that is, 3G and WiFi.

For example, the terminal device 100, if the rearrangement rate exceeding the preset limit rate (eg 30%) of the reordering (eg 0%, 40%) rate calculated for each of the 3G, WiFi, the limit rate (E.g., 30%), the WiFi-related rearrangement rate (eg, 40%) can be provided to the management device 400, and at the same time, it can also provide another access network, that is, 3G-related rearrangement rate (eg, 0%). have.

Alternatively, the terminal device 100 may provide the management device 400 with the reordering calculated for each of 3G and WiFi for each preset reporting period.

Alternatively, the terminal device 100 calculates the reordering rate as described above using the preset number of partial data for each 3G and WiFi (for example, 100), and manages the reordering calculated for each 3G and WiFi. It may be provided to the device 400.

The management device 400 may receive and obtain a reordering rate calculated for a specific access network, that is, 3G and WiFi, from the terminal device 100.

Accordingly, the management apparatus 400 may duplicately transmit the partial data to be transmitted later corresponding to each of the 3G and the WiFi through two or more access networks, that is, the 3G and the WiFi, based on the rearrangement rates of the 3G and the WiFi, respectively. Determine whether or not. Preferably, the management apparatus 400, based on the re-arrangement rate of each of the 3G, WiFi, whether the partial data to be transmitted later corresponding to each of the 3G, WiFi redundant transmission over the other access network of two or more access networks You can decide whether or not.

For example, as described above, the management device 400 may obtain the 3G related rearrangement rate (eg, 0%) and the WiFi related rearrangement rate (eg, 40%) from the terminal device 100. Accordingly, the management device 400 determines whether there is a reordering rate exceeding a preset limit rate (eg, 30%) among the acquired 3G-related reordering rate (eg, 0%) and WiFi-related reordering rate (eg, 40%). By checking whether or not, it is possible to determine whether to transmit duplicated based on the reordering rate.

That is, if it is determined that there is a WiFi-related rearrangement rate (eg, 40%) exceeding the limit rate (eg, 30%), the management device 400 connects another part to the partial data to be transmitted later in response to WiFi. It may be decided to redundantly transmit over a network such as 3G.

Thus, the management device 400 may duplicately transmit the partial data to be transmitted later through 3G in response to WiFi.

Hereinafter, a configuration of a multi-network based simultaneous transmission receiving apparatus, that is, a receiving apparatus according to the present invention will be described in more detail with reference to FIG. 2. For convenience of description, reference numbers of the terminal apparatus 100 are referred to based on the downlink, and reference is made to the transmitting apparatus 400 using the reference numbers of the management apparatus 400.

The communication unit 110 refers to a communication module for interfacing with the first network device 200 using the 3G network and interworking with the second network device 300 using the WiFi network.

Thus, the communication unit 110 may receive a plurality of pieces of partial data divided from the transmission target data from the above-mentioned transmission apparatus 400 through two or more access networks (eg, 3G, WiFi).

The information checking unit 120 confirms specific partial data received through a specific access network among two or more access networks (eg, 3G, WiFi), and a network related to an order of transmission from the specific partial data through the specific access network. Check the transmission order information.

That is, the information checking unit 120 confirms the partial data received through each specific access network, that is, the access network (eg, 3G, WiFi).

The information confirming unit 120 checks the partial data received through each specific access network, that is, the access network (eg, 3G, WiFi), and then transmits the data from the checked partial data through the access network (eg, 3G, WiFi). Check the network transmission sequence information related to the sequence.

For example, referring to FIG. 7, the information checking unit 120 may check partial data of the transmission order information 4, 5, and 7 received through 3G, and the transmission order information 1, 6, and 2 received through WiFi. You can check the partial data of, 3,8.

Then, the information checking unit 120, the network transmission order information 1, 4, 2, 3 related to the order of transmission through the WiFi from the partial data of the transmission order information 1, 6, 2, 3, 8 received via WiFi , 5 can be checked, and network transmission order information 1,2,3 related to the order of transmission through WiFi can be confirmed from the partial data of the transmission order information 4, 5, and 7 received through 3G.

The control unit 130, based on the network transmission order information of the partial data received through each of the specific access network, that is, access network (eg, 3G, WiFi), the rearrangement rate with respect to each of the access network (eg, 3G, WiFi) Can be calculated.

Preferably, the controller 130 is associated with the specific access network by using the number of specific partial data corresponding to the specific access network and the number of partial data requiring reordering according to the network transmission order information in the specific partial data. The reordering rate can be calculated.

In more detail with reference to FIG. 7, the controller 130 may transmit the partial data number 5, the transmission order information 1, 6, 2, 3 of the transmission order information 1, 6, 2, 3, and 8 received through WiFi. In the partial data of 8, the number 2 of partial data (partial data of the network transmission order information 2, 3) required to be rearranged in accordance with the network transmission order information 1, 4, 2, 3, 5 is checked and associated with WiFi. We can calculate the reordering rate 2/5 (= 40%) by

On the other hand, the control unit 130, the network transmission order information 1, 2, 3 in the partial data number 3, the transmission order information 4, 5, 7 of the transmission order information 4, 5, 7 received through 3G Accordingly, the number of partial data (none) requiring realignment can be checked, and the reordering rate 0/3 (= 0%) can be calculated in relation to 3G.

In addition, the controller 130 may provide the transmitting apparatus 400 with the reordering rate calculated for each specific access network, that is, 3G and WiFi.

For example, the control unit 130, if the re-arrangement rate exceeding the preset limit rate (eg 30%) of the reordering (eg 0%, 40%) rate calculated for each of 3G and WiFi, the limit rate ( For example, the WiFi-related rearrangement rate (eg, 40%) over 30%) may be provided to the transmitter 400, and at this time, another access network, that is, 3G-related rearrangement rate (eg, 0%) may be provided. .

Alternatively, the controller 130 may provide, to the transmitter 400, the reordering calculated for each of 3G and WiFi for each preset reporting period.

Alternatively, the controller 130 calculates the reordering rate as described above using the preset number of partial data for each of 3G and WiFi (for example, 100), and transmits the reordering calculated for each of 3G and WiFi. 400 can be provided.

Accordingly, the transmitter 400 may determine whether to repeatedly transmit the partial data to be transmitted later through another access network based on the re-arrangement rates of 3G and WiFi, respectively, If it is determined that the transmission is redundantly transmitted through 3G in response to the access network (for example, WiFi), the partial data to be transmitted later (for example, partial data of the transmission sequence information 2 and 3 of FIG. 8) is duplicated through 3G. Can transmit
