The communication network of above-mentioned different systems is based on ICP/IP protocol when the transmission of business datum is realized
(Transmission Control Protocol/Internet Protocol, transmission control protocol/Internet Interconnection association
View), AP equipment is capable of the communication network of compatible above-mentioned different systems simultaneously, such that it is able to logical by the multiple of above-mentioned different systems
Communication network carries out data transmission simultaneously.
In order to make it easy to understand, the present embodiment with the currently available communication network of AP equipment as 3G network and WIFI network allusion quotation
It is specifically described as a example by type scene.What deserves to be explained is, in actual applications, the available communication network of AP equipment and not only
It is limited to two.
202nd, AP equipment obtains the request of data that TE (Terminal Equipment, terminal device) is initiated.
What deserves to be explained is, AP equipment can obtain the request of data that TE is initiated by following at least 2 kinds modes：1) AP sets
It is standby to receive service request from TE, the service request is split as at least 2 request of data.
For example：AP equipment receives the web page browsing request of TE initiations, and web page browsing request includes video data, sound
Frequency evidence and text data, then AP equipment can by the web page browsing request be divided into 3 request of data：I.e. video data please
Ask, voice data is asked and text data requests.
2) AP equipment receives the request of data of TE transmissions, i.e. AP equipment from TE direct access request of data from TE.
TE in the embodiment of the present invention is the terminal for possessing radio communication function, for example：PC (Personal Computer,
Personal computer), notebook computer, smart mobile phone, panel computer etc..
203rd, AP equipment detects the transmission rate of current 3G network and WIFI network, determines transmission rate highest communication network
Network, the specified network of the request of data that the communication network is obtained as AP.
For example：AP equipment can send ping message (or other kinds of service message) by the webserver,
Time interval according to response message is returned determines transmission rate.
What deserves to be explained is, the transmission rate of communication network depends on idle bandwidth, data transmission link in 3G network
Bandwidth depends on the bandwidth of the 3G network that operator provides, and the bandwidth of data transmission link depends on WIFI hot spot in WIFI network
The bandwidth of offer.In actual applications, TE often initiates multiple parallel service requests or request of data (for example：Browsing
While webpage, TE can initiate the following published article part of file download request), in also terminating the multiple business being currently running
Certain business, so the idle bandwidth of 3G network and WIFI network is real-time change.In order to ensure transmission rate, AP equipment exists
After obtaining the request of data that TE is initiated, current idle bandwidth maximum, transmission rate highest communication network can be selected as the number
According to the specified network of request.
For example, a width of 2M of band provided with 3G network, as a example by a width of 4M of band that WIFI hot spot is provided：When TE initiates video counts
During according to request, if 3G network and WIFI network are all in idle condition, AP equipment can realize the video by WIFI network
Request of data；If the realization of video data request occupies bandwidth (the now idle band of WIFI network of WIFI network 1M
A width of 3M, the idle bandwidth of 3G network is 2M), then AP equipment can be selected when next request of data that TE is initiated is obtained
WIFI network as next request of data specified network.
Specifically, in order to the network structure of description the present embodiment that is clear, completing distributes information, next being obtained with AP equipment
TE is taken to initiate to be illustrated as a example by web page browsing request, video playback request and file download request successively：
In order to make it easy to understand, it is assumed herein that a width of 2M of the band of 3G network, a width of 4M of band of WIFI network；Realize web page browsing
The bandwidth that request, video playback request and file download request take is followed successively by 1M, 2M, 2M；The then distribution condition of communication network
It is as follows：
1. AP receives the web page browsing request that TE is initiated, and detects the idle bandwidth of current 3G network for 2M, WIFI network
Idle bandwidth be 4M, selection WIFI network realize the web page browsing ask；
2. AP receives the video playback request that TE is initiated, and detects the idle bandwidth of current 3G network for 2M, WIFI network
Idle bandwidth be 3M, selection WIFI network realize the video playback ask；
3. AP receives the file download request that TE is initiated, and detects the idle bandwidth of current 3G network for 2M, WIFI network
Idle bandwidth be 1M, selection 3G network realize this document download request.
It is as shown in Figure 3 according to the network structure that the above method is distributed.
Further, it is preferred that when the web page browsing that AP equipment receives TE initiations is asked, AP equipment can be by the webpage
Browse request is divided into 3 request of data：I.e. video data request, voice data are asked and text data requests, and are followed successively by
3 request of data that fractionation is obtained distribute specified network of the transmission rate highest network as the request of data such that it is able to
Make full use of the bandwidth resources of multiple communication networks so that TE obtains message transmission rate higher.
204th, AP equipment is that each request of data sets up data transmission link in the specified network, and is recorded as each data
Asking the link connection information set up, the link connection information includes the mark of the communication network for request of data distribution
Know.
Wherein, link connection information can characterize the network information that current AP equipment is each request of data distribution, for drawing
Lead each request of data and obtain business datum.
What deserves to be explained is, it is different in TE if different request of data is initiated by different application programs
Application program is linked using different ports and same connection handshake request from outer net, then also record has in link connection information
The corresponding port numbers of each request of data.
205th, AP equipment by the data transmission link set up for each request of data by request of data send to server with
Obtain data.
That is, the method provided using the present embodiment, when business of networking is carried out, the online bandwidth of TE is that AP sets to TE
The bandwidth sum of the standby whole communication networks supported, networking speed can be significantly improved, and effectively improve Consumer's Experience.
206th, when AP equipment is that the data transmission link that a certain request of data is set up needs to disconnect, AP is broken as the data
The data transmission link set up is asked, the load of link is discharged, and delete the link connection information on the request of data.
Wherein, following scene is included but is not limited to " for the data transmission link that a certain request of data is set up needs to disconnect "：
The corresponding data transfer of the request of data has been completed or the request of data is terminated by TE.
Data transmission method provided in an embodiment of the present invention, TE can be carried out by the available multiple communication networks of AP equipment
Data transfer.Using method provided in an embodiment of the present invention, the online bandwidth of TE is the available multiple communication networks of AP equipment
Bandwidth sum, compared with prior art, is capable of the online bandwidth of effective TE, user is obtained preferable online experience.
