Problems solved by technology

[0005] When the user data flow is switched from an LTE network (such as a cellular network) to a WiFi network (such as a WLAN) for some reason (such as network congestion), and the user terminal accesses both the cellular network and the WLAN network at the same time, it will In this way, users use different IP addresses in the LTE network and WiFi network, according to the traditional offload data transmission method, the IP address bound to the user application will be changed, resulting in interruption or restart of the user application. question

Embodiment 1

[0042] This embodiment provides a split data transmission method, such as image 3 As shown in , it mainly includes steps:

[0043] Step 11: Obtain the IP address IP1 of the user terminal on the first network;

[0044] Step 12: Obtain the physical address MAC2 of the second network access module of the user terminal;

[0045] Step 13: When the user data stream is diverted from the first network to the second network due to some reasons, such as network congestion or low signal-to-noise ratio, etc., the downlink service of the user terminal:

[0046] According to the obtained address, the IP message whose destination address is the IP address of the user terminal in the first network is encapsulated into a message in a format corresponding to the media access layer of the second network;

[0047] Step 14: Transmit the packet encapsulated in the format corresponding to the second network media access layer to the user terminal.

[0048]The above-mentioned first network and th...

Embodiment 2

[0051] In this embodiment, the method for offloading data provided by the present invention is described in detail by taking the first network as an LTE network and the second network as a WiFi network as an example.

[0052] Since the multi-service data gateway MSG is usually a service aggregation point of a heterogeneous network, in this embodiment, the offload data device can be integrated in the packet multi-service data gateway MSG; since the first network in this embodiment is an LTE network, The second network is a WiFi network, therefore, the first network access module of the user terminal UE is an LTE module, and the second network access module of the user terminal UE is a WiFi module.

[0053] Such as Figure 4 As shown in , the user terminal is connected to the LTE network and the WiFi network respectively, and has an IP address LET-IP in the LTE network, and an IP address WiFi-IP in the WiFi network; at the same time, the access module of the user terminal in the...

Embodiment 3

[0060] This embodiment provides a shunt data transmission device, such as Figure 6 As shown in , it mainly includes:

[0061] Address obtaining module: used to obtain the IP address of the user terminal on the first network, and obtain the physical address of the second network access module of the user terminal;

[0062] Encapsulation and transmission module: used to encapsulate the IP packet whose destination address is the IP address of the user terminal in the first network into the second network according to the obtained address when the downlink service of the user terminal is distributed from the first network to the second network The message in the format corresponding to the media access layer is then transmitted to the user terminal through the second network.

[0063] Since the multi-service data gateway MSG is usually a service aggregation point of a heterogeneous network, in this embodiment, the distribution data device can be integrated into the packet multi-...

Abstract

The invention relates to the technical field of communication, in particular to a distributing data transmission method, distributing data transmission equipment and a user terminal. The distributing data transmission method provided by the embodiment of the invention comprises the following steps of obtaining an IP (internet protocol) address of the user terminal at a first network and a physical address of a second network access module of the user terminal; and when downlink services of the user terminal are distributed from the first network to the second network, according to the obtained addresses, packaging the IP message of the target address which is the IP address of the first network of the user terminal into the message with the corresponding format of a media access layer of the second network, and transmitting the message to the user terminal through the second network. As the IP address which is bound by the user application is not changed, the seamless switching of the downlink services from the first network to the second network is realized, the problem of unnecessary interruption and restarting of the user application is avoided, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a split data transmission method, split data transmission equipment and a user terminal. Background technique [0002] WLAN (Wireless Local Area Network, Wireless Local Area Network) refers to a group of computers and related equipment interconnected using IEEE802.11 wireless technology. And it has gradually become a vital part of the computer network, and it is widely used in fields that require mobile data processing or cannot carry out physical transmission medium wiring. With the formulation and development of the IEEE802.11 wireless network standard, the wireless network technology is more mature and perfect. And has been widely used in many industries, such as financial securities, education, large enterprises, industrial and mining ports, government agencies, hotels, airports, military and so on. Products mainly include: wireless access point, wireless...
