Example 1

An embodiment of the present invention provides a data transmission method, as shown in FIG. 1, the method includes:

101. Access the hotspot device to obtain a data request initiated by the terminal device.

It is worth noting that the access hotspot device in this embodiment may be an AP (AccessPoint, access point) device in a mobile communication network, or other network element devices with AP functions, such as wireless routers, wireless gateways, etc. , is not limited here.

102. The hotspot access device selects a communication network with the highest current transmission rate from at least two available communication networks as the designated network for the data request.

For ease of understanding, this embodiment takes an AP device as an example for illustration; the above-mentioned "available communication network" refers to a communication network that the AP supports the network standard of the network and has the authority to use the network for data transmission, including but not limited to : GPRS (General Packet Radio Service, General Packet Radio Service) network, 3G network, 4G (4th-Generation, fourth generation mobile communication technology) network, WIFI network, WAP network, and wired network etc.; A scenario where there are two communication networks available.

Specifically, the AP can determine the currently available communication network by querying its own network status. For example, the AP can determine whether the 3G network is an available communication network by querying the 3G wireless air interface message; determine whether there is a WIFI network through the real-time scanning results of WIFI available communication network.

103. The hotspot access device establishes a data transmission link in the specified network.

In the data transmission method provided by the embodiment of the present invention, the terminal device can perform data transmission through multiple communication networks available to the AP device. Using the method provided by the embodiment of the present invention, the Internet access bandwidth of the terminal device is the sum of the bandwidths of multiple communication networks that the AP can use. Compared with the prior art, the Internet access bandwidth of the user terminal device can be effectively improved, and the The received data transmission requirements are allocated to a communication network with a high transmission rate, so that users can obtain a better online experience.

Example 2

An embodiment of the present invention provides a data transmission method, as shown in FIG. 2, the method includes:

201. The AP device detects and determines currently available communication networks, where there are at least two available communication networks.

It is worth noting that the AP device in this embodiment may also be replaced by network element devices with specific AP functions such as wireless routers and wireless gateways, which are not limited here. Specifically, the above "available communication network" refers to the communication network that the AP supports the network standard of the network and has the authority to use the network for data transmission. The communication network includes but is not limited to: GPRS network, 3G network, 4G network , WIFI network, WAP network, and wired network, etc. Among them, 3G and 4G networks include various standards. For example, 3G networks include: CDMA2000 (Code Division Multiple Access, Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), WiMAX (Worldwide Interoperability for Microwave Access, Global Microwave Interconnection Access) 4 standards.

The above-mentioned communication networks of different standards are all based on the TCP/IP protocol (Transmission Control Protocol/Internet Protocol) when realizing the transmission of business data, and the AP device can be compatible with the communication networks of the above-mentioned different standards at the same time, so that Simultaneous data transmission through multiple communication networks of different standards mentioned above.

For ease of understanding, this embodiment takes a typical scenario where the currently available communication network of the AP device is a 3G network and a WIFI network as an example for specific description. It should be noted that, in practical applications, the communication networks available to the AP device are not limited to two.

202. The AP device obtains a data request initiated by a TE (Terminal Equipment, terminal device).

It is worth noting that the AP device can obtain the data request initiated by the TE in at least two ways as follows: 1) The AP device receives the service request from the TE, and splits the service request into at least two data requests.

For example, when an AP device receives a web browsing request initiated by a TE, and the web browsing request includes video data, audio data, and text data, the AP device can divide the web browsing request into three data requests: video data request, audio data request, and audio data request. Data Request and Text Data Request.

2) The AP device receives the data request sent by the TE from the TE, that is, the AP device directly obtains the data request from the TE.

The TE in the embodiment of the present invention is a terminal with a wireless communication function, such as a PC (Personal Computer, personal computer), a notebook computer, a smart phone, a tablet computer, and the like.

203. The AP device detects the transmission rates of the current 3G network and the WIFI network, determines the communication network with the highest transmission rate, and uses the communication network as a designated network for the data request obtained by the AP.

For example, the AP device can send a ping message (or other types of service messages) to the network server, and determine the transmission rate according to the time interval for returning the response message.

It is worth noting that the transmission rate of the communication network depends on the idle bandwidth, the bandwidth of the data transmission link in the 3G network depends on the bandwidth of the 3G network provided by the operator, and the bandwidth of the data transmission link in the WIFI network depends on the bandwidth provided by the WIFI hotspot. bandwidth. In practical applications, TE often initiates multiple parallel service requests or data requests (for example, while browsing the web, TE initiates a file download request to download files), and also terminates the currently running multiple service requests. A certain business, so the idle bandwidth of the 3G network and the WIFI network changes in real time. In order to ensure the transmission rate, after the AP device obtains the data request initiated by the TE, it will select the communication network with the largest idle bandwidth and the highest transmission rate as the designated network for the data request.

For example, take the 2M bandwidth provided by the 3G network and the 4M bandwidth provided by the WIFI hotspot as an example: when the TE initiates a video data request, if both the 3G network and the WIFI network are idle, the AP device will implement the video data through the WIFI network. Data request; if the implementation of the video data request occupies 1M bandwidth of the WIFI network (at this time, the idle bandwidth of the WIFI network is 3M, and the idle bandwidth of the 3G network is 2M), then when the AP device obtains the next data request initiated by the TE , the WIFI network will be selected as the specified network for the next data request.

Specifically, in order to clearly and completely describe the network structure allocation information of this embodiment, the following takes the AP device to obtain TE to initiate a web page browsing request, video playback request and file download request as an example for example:

For ease of understanding, it is assumed here that the bandwidth of the 3G network is 2M, and the bandwidth of the WIFI network is 4M; the bandwidth occupied by web browsing requests, video playback requests, and file download requests is 1M, 2M, and 2M in turn; the distribution of the communication network as follows:

①AP receives the webpage browsing request initiated by TE, detects that the idle bandwidth of the current 3G network is 2M, and the idle bandwidth of the WIFI network is 4M, and selects the WIFI network to realize the webpage browsing request;

②AP receives the video playback request initiated by TE, detects that the idle bandwidth of the current 3G network is 2M, and the idle bandwidth of the WIFI network is 3M, and selects the WIFI network to implement the video playback request;

③ AP receives the file download request initiated by TE, detects that the idle bandwidth of the current 3G network is 2M, and the idle bandwidth of the WIFI network is 1M, and selects the 3G network to realize the file download request.

The network structure diagram allocated according to the above method is shown in Fig. 3 .

Further, preferably, when the AP device receives the webpage browsing request initiated by the TE, the AP device can divide the webpage browsing request into three data requests: a video data request, an audio data request, and a text data request, and sequentially split the webpage browsing request into three data requests: The 3 divided data requests are allocated to the network with the highest transmission rate as the designated network for the data request, so that the bandwidth resources of multiple communication networks can be fully utilized, enabling TE to obtain a higher data transmission rate.

204. The AP device establishes a data transmission link for each data request in the specified network, and records the link connection information established for each data request, and the link connection information includes the information of the communication network allocated for the data request. logo.

Wherein, the link connection information can represent the network information allocated by the current AP device for each data request, and is used to guide each data request to obtain service data.

It is worth noting that if different data requests are initiated by different applications, different applications in TE and external network links use different ports and the same connection handshake request, and the link connection information also records The port number corresponding to each data request.

205. The AP device sends the data request to the server through the data transmission link established for each data request to obtain the data.

That is to say, with the method provided in this embodiment, when the TE performs Internet access services, the Internet access bandwidth of the TE is the sum of the bandwidths of all communication networks supported by the AP device, and the Internet access speed can be significantly improved, effectively improving user experience.

206. When the data transmission link established by the AP device for a certain data request needs to be disconnected, the AP disconnects the data transmission link established for the data request, releases the load of the link, and deletes the link related to the data request connection information.

Wherein, "the data transmission link established for a certain data request needs to be disconnected" includes but is not limited to the following scenarios: the data transmission corresponding to the data request has been completed, or the data request is terminated by the TE.

In the data transmission method provided by the embodiment of the present invention, the TE can perform data transmission through multiple communication networks available to the AP device. By adopting the method provided by the embodiment of the present invention, the Internet access bandwidth of the TE is the sum of the bandwidths of multiple communication networks available to the AP device. Compared with the prior art, the Internet access bandwidth of the TE can be effectively improved, so that users can obtain a better Internet access experience .
