Amount；Registrar is for binding private ip and the card number of APN card, it is provided that the registration of card number and inquiry service；Web proxy services
Device, for providing all rotating functions of the network information, such as sends an external resource access request when terminal end, this request quilt
Proxy server identification and by proxy server on behalf of outwards asking resource, when external resource server responds this access request
Time, this response results is fed back to terminal by proxy server again.
In the present embodiment, mobile terminal can be mobile phone, and panel computer etc. has the equipment of network access functions.At end
When end uses APN card to carry out network access request, the flow-control module being positioned in corporate intranet receives the network of terminal and accesses
Ask and obtain URL (Uniform Resource Locator, the URL) address of this network access request, i.e.
The network address, the network information resource that terminal will access is pointed in this network address.
Step S20, determines the type of service of described network access request, described service class according to the URL address got
Corresponding network traffics allocated in advance by type.
After flow-control module gets the URL address of described network access request, further according to the URL ground got
Location determines that the type of service of described network access request, described type of service have allocated corresponding network traffics in advance.
In the present embodiment, controlling to realize the fine granularity of flow, those skilled in the art can be primarily based on URL ground
Network is classified by location, and the URL of standard generally comprises type of server, host name, path and filename, service class
Type can divide according to different filenames, such as can be divided into basic business (such as word, picture, link), show business
Business (such as video, music), downloading service and other business etc..Usually, there is larger difference in the flow of different business consumption, than
As less in word class business consumed flow and video class business consumed flow is more, therefore Network is classified and with evidence
The used flow that different business demands is differently configured, it is possible to realize management and control more targeted to flow.
Then, the used network flow data by the type of service classified in advance and for every kind of type of service configuration is deposited
Storage is in respective memory unit, and memory element is additionally operable to real time record residual flow.Flow-control module is according to URL address search
Business categorical data in memory element, and then can determine the type of service of network access request and the residual flow of correspondence.

To realize user to the individual cultivation of different business utilizable flow and amendment by terminal related service, can enter in being embodied as
Row selects flexibly.
Step S30, it is judged that whether the residual flow of the type of service of described network access request currently correspondence meets is preset
Use condition.
Flow-control module judges whether the residual flow of the type of service currently correspondence of described network access request meets
The use condition preset, such as, can disappear residual flow currently corresponding for type of service more than or equal to network access request
The flow of consumption is as default use condition, if condition is not satisfied, then refusal network accesses and returns error message to terminal.
Step S40, if the residual flow of the type of service of described network access request currently correspondence meets default use
Condition, then the network traffics consumed described network access request according to described residual flow are controlled.
Such as, there is residual flow and residual flow more than or equal to working as when the business classification belonging to described URL address
When front network access request needs the flow consumed, it is determined that this residual flow meets default use condition, now, flow-control
Module can send this request to Web proxy server and automatically deduct current network access request consumption from residual flow
Flow；Certainly, by terminal service, flow-control module can also display to the user that the lower residue of current this business classification is how many
Flow, by the user decide whether that network to be proceeded accesses.
In the present embodiment, flow-control module receives the network access request that terminal sends when using APN card, obtains
The URL address of described network access request；The type of service of described network access request is determined according to the URL address got,
Described type of service has allocated corresponding network traffics in advance；Judge the type of service currently correspondence of described network access request
Whether residual flow meets the use condition preset；The most then according to described residual flow, described network access request is consumed
Network traffics be controlled.The present embodiment is by arranging what this enterprise was issued by flow-control module realization in corporate intranet
APN card carries out flow-control, it is not necessary to additionally develop for APP internal logic；Additionally, the present embodiment is by URL address pair
Network is classified, and is pre-configured with the utilizable flow under every APN card each business classification, is receiving the net of terminal
During network access request, determined the type of service of described network access request by URL address, and the most right by this type of service
The residual flow answered realizes the control of the network traffics to this access request.The present embodiment is by the flow to different network service
It is controlled and limits such that it is able to realizing the control using flow more to become more meticulous on APN card.
Further, with reference to the schematic flow sheet that Fig. 3, Fig. 3 are inventive network flow control methods the second embodiment.Base
Before the embodiment shown in above-mentioned Fig. 1, described step S10, it is also possible to including:
Step S50, the type of service different for network access request distributes corresponding network traffics.
As a kind of embodiment, flow-control module can be the type of service distribution that network access request is different in real time
Corresponding network traffics, such as, obtain the residual flow that current APN card is total, then according to every kind of traffic assignments set in advance
Flow percentage, calculating should be for every kind of traffic assignments how many network traffics, to realize the dynamic distribution of network traffics；When
So, flow-control module can also be that the type of service distribution that network access request is different is corresponding according to certain time interval
Network traffics, can be arranged in being embodied as flexibly.
In the present embodiment, by distributing corresponding network traffics for the type of service different for network access request, it is achieved
The dynamic distribution of network traffics, i.e. flow-control module can make full use of the residual flow of current APN card, it is to avoid certain industry
Residual flow under service type is more and can not get the situation generation used.
Further, reference Fig. 4, Fig. 4 is the refinement flow process in second embodiment of the invention being controlled network traffics
Schematic diagram.Based on the embodiment shown in above-mentioned Fig. 3, described step S30 may include that
Step S31, obtain described network access request request data package take flow, and accessed by described network please
The residual flow of the type of service asked currently correspondence is as the first residual flow；
Step S32, if the flow that takies of described request data package is less than or equal to described first residual flow, then judges institute
State the first residual flow and meet default use condition.
Described step S40 may include that
Step S41, if the residual flow of the type of service of described network access request currently correspondence meets default use
Condition, then update, according to the flow that takies of described request data package, the network traffics that described network access request consumes.
In the present embodiment, the flow consumed due to network access request is usually by request data package size and number of responses
Determining according to bag size, therefore, flow-control module can first obtain the request data package of described network access request and calculate
Go out and take uninterrupted, then this request data package is taken flow and current corresponding business classification lower residual flow that is first residue
Flow contrasts, if the flow that takies of described request data package is less than or equal to the first residual flow, then judges the first residue
Flow meets default use condition, and request data package now takies the flow network traffics as consumption, to complete to consume
The renewal of network traffics, then network request is forwarded to proxy server；If described request data package to take flow big
In current residual flow, the most do not update network traffics and return error message to terminal.
Further, with reference to Fig. 5, Fig. 5 it is another refinement in second embodiment of the invention, network traffics being controlled
Schematic flow sheet.Described step S30 can also include:
Step S33, obtain described network access request response data packet take flow, and by described first residual stream
The difference taking flow of amount and described request data package is as the second residual flow；
Step S34, if the flow that takies of described response data packet is less than or equal to described second residual flow, then judges institute
State the second residual flow and meet default use condition.
Described step S40 can also include:
Step S42, if the residual flow of the type of service of described network access request currently correspondence meets default use
Condition, then update, according to the flow that takies of described response data packet, the network traffics that described network access request consumes.
When receiving the response that network accesses, flow-control module obtains corresponding Web server by proxy server
Response data packet also calculates and takies uninterrupted, meanwhile, by taking of described first residual flow and described request data package
The difference of flow is as the second residual flow, then this response data packet takies flow residual stream lower with current corresponding business classification
I.e. the second residual flow of amount contrasts, if the flow that takies of described request data package is less than or equal to the second residual flow, this
Time response data packet taken flow as the network traffics consumed, to complete the renewal of the network traffics consumed, meanwhile, by net
Network response is forwarded to mobile terminal, completes network access procedure；If the flow that takies of described response data packet is more than current residual
Flow, does not the most update network traffics and returns error message to terminal.
The present embodiment considers request and two stages of response of terminal network access request, carries out network access in terminal
During request, the use flow in two stages is respectively controlled by flow-control module by the condition preset, and then judgement is
No permission terminal proceeds network and accesses, it is possible to ensure that the residual flow under every kind of business classification will not be for negative value, i.e. every kind
The flow that network access under business classification consumes, not over preset value, meets user's fine-grained flow-control demand.
Further, with reference to the schematic flow sheet that Fig. 6, Fig. 6 are inventive network flow control methods the 3rd embodiment.Base

Row step: determine the type of service of described network access request according to the URL address got, described type of service is allocated in advance
There are corresponding network traffics.
In the present embodiment, the registration of APN card includes the write of APN card data, such as system of real name information, the card number of APN card
Binding information etc. with private ip.After flow-control module extracts private ip from URL, private ip can be uploaded to registration clothes
Business device, registrar detects whether the log-on message of this APN card meets pre-conditioned, must be such as system of real name register and
Card number is bound with private ip, if this private ip is bound with APN card, and APN card is system of real name registration, then sentence
Fixed described APN card is registered, and now, registrar returns registered message to flow-control module, and flow-control module is again
The type of service of described network access request is determined according to the URL address got；Otherwise, if this private ip does not sticks into APN
Row binding, or the registration of APN card not system of real name, then judge that described APN card is unregistered, and now refusal network accesses and to terminal
Return error message.Certainly, what whether APN card was registered pre-conditioned can be arranged flexibly, the most only needs private ip and APN to stick into
Row binding.
Especially, if the URL that flow-control module gets is registration message, the most directly send the message to registration clothes
Business device, is completed the registration service such as binding of private ip and APN card, so that mobile terminal can carry out network by registrar
Access.
It should be noted that the IP address that private ip i.e. terminal uses in local area network, connect shakiness at terminal network
Fixed, or when being switched to the reasons such as data cube computation to cause network to reconnect by WIFI, terminal is required for uploading registration message to note
Volume server, to complete the binding of new IP and card number, reason is that the private ip of APN card is dynamically distributed by operator, often
Secondary terminal reconnects network and IP all can be caused to change.Flow-control module middle extraction private ip from URL ground just can identify and be
Which APN is stuck in carries out network access.
