Prior art is using DPI technology, it is achieved during for the policy control of the business of specific SP, is usually and issues control in advance
System strategy, in control strategy in addition to including concrete policy content, in addition it is also necessary to include the scope being suitable for, this scope is usually
By a URL(Uniform/Universal Resource Locator, URL) collect incompatible and be given.
During user accesses webpage, PCEF(Policy and Charging Enforcement Function, strategy and meter
Take execution function) or TDF(Traffic Detection Function, flow monitoring function) utilize DPI technical point to separate out
The URL of accessed webpage, if this URL belongs to aforementioned set of URL and closes, then uses aforementioned special strategy control to this access request
System, otherwise, uses common policy control to this access request.
But, in actual applications, often there is situations below: a main application page may be embedded with the resource of outer net,
Such as, may be embedded with the picture resource from Sina in a facebook page, so, user is accessing this facebook
During the page, if having accessed the picture resource of this Sina, then the target that PCEF or TDF identifies access request is corresponding
URL is also not belonging to the set of URL conjunction that facebook control strategy is corresponding, then can be used for common policy control.But,
For certain specific transactions, either access the outer net resource that Intranet resource is also embedded into, all should use and specifically control plan
Slightly.It is to say, prior art is using DPI technology, it is achieved during for the policy control of the business of specific SP, it is impossible to suitable

The most such as, control in (PCC, Policy and Charging Control) framework in strategy and charging, policy control
System, including omiting and charging rule functions (PCRF, Policy and Charging Rule Function) and tactful and charging
Perform function (PCEF, Policy and Charging Enforcement Function).Wherein PCEF can be that gateway sets
A standby part, for realizing the detection of business, strategy execution and billing function based on stream.PCRF can accept from PCEF
Input, for implementation strategy control decision and based on flow based charging control function, to PCEF provide about business data flow detection,
Gate, network control function based on flow based charging (in addition to diameter credit control), the self-defined information in conjunction with PCRF makes PCC decision.
Wherein the work process between PCEF and PCRF is not repeated herein.
In the embodiment of the present invention, in order to when using special policy control for specific transactions so that special strategy control
System can either be applied to the main application page of business, can apply to again the outer net resource being embedded in the main application page, can be to master
The URL of outer net resource embedded in the application page modifies, and mainly adds outer net resource identification in the URL of outer net resource.
This outer net resource identification includes the identification information of specific transactions, say, that this outer net resource identification is used for indicating this resource to need
The specific control strategy using certain specific transactions is controlled, and which specific transactions indicates be.So implementation strategy control
The entity of system just can be determined need to use certain special control strategy to control according to this outer net resource identification in URL
System, and the specific transactions of correspondence can be known, then according to the control strategy of this specific transactions, the request of this this resource of access is entered
Row policy control.Below this is introduced in detail.
Seeing Figure 1B, aforementioned policy controlling system can perform the policy control method that the embodiment of the present invention provides, including following
Step:
S101: policy controlling system obtains the control strategy information for specific transactions, and described control strategy information includes control
Policy content processed, and described control strategy content be suitable for uniform resource position mark URL set and outer net resource identification,
Described set of URL closes the URL of each the main application page including described specific transactions, and described outer net resource identification includes
The identification information of described specific transactions；
Firstly the need of explanation, include concrete control strategy content in control strategy information, such as concrete how to this spy
Determine business and carry out charging, how to distribute bandwidth for this specific transactions, or how this specific transactions is carried out location-based application control
System etc., will also include the scope of application information of this control strategy content simultaneously.Scope of application information is usually by a set of URL
Incompatible expression, the element in the conjunction of this set of URL is exactly the URL of each main application page of this specific transactions.Wherein, so-called
The main application page, be primarily referred to as some pages of specific transactions self, the URL of these pages is directed to this specific transactions
The server of oneself.
As a example by PCC framework, control strategy information (URL of the most main application page) can be to be provided, concurrently by SP
Cloth is in PCRF, then is handed down to PCEF by PCRF.Wherein the operation principle between PCRF and PCEF is with reference to prior art, example
As being dynamic socket pattern or static interface pattern.Except concrete control strategy content and scope of application information thereof it
Outward, in embodiments of the present invention, also including an outer net resource identification in the control strategy information that PCRF issues, this mark needs
Embody the identification information of the specific transactions of correspondence.Such as, for this specific transactions of facebook, this outer net resource identification
Can be src=facebook etc..Certainly, outer net resource identification can also is that other form, hereinafter has detailed Jie
Continue.
S102: after policy controlling system receives accessing page request, the Web server corresponding from the accessed page obtains
Resource content, and obtain the URL of the accessed page；
The accessing page request of subscriber equipment typically can first be sent to policy controlling system (PCEF the most therein or
TDF), the Web server of correspondence, accordingly, the page that Web server returns it are transmitted to the most again by policy controlling system
Resource content also can first arrive policy controlling system, and afterwards, this page resource content is returned to user by policy controlling system again
Equipment end.Exactly because access request and response all can be through policy controlling systems, the page could be visited by policy controlling system
The request of asking carries out various policy control.Concrete, policy controlling system can use DPI technology, therefore, is receiving certain page
After the access request of face, it is possible to utilize DPI technical limit spacing to the URL of the accessed page.
S103: when determining the URL of the main application page that URL is described specific transactions of the described accessed page, to described
The origin url of the outer net resource comprised in resource content is modified so that described amended URL includes described outer net
Resource identification, and the resource content including amended URL is returned to subscriber equipment；
After getting the URL of the accessed page, can fit with the control strategy content of each specific transactions got in advance
Each URL compare, if the control strategy content belonging to certain specific transactions be suitable for set of URL close, then can make
With the control strategy of this specific transactions, this visit request is carried out policy control, including charging control, bandwidth control etc..
Meanwhile, after getting the resource content of the accessed page that Web server returns, need resource content is entered
Row processes, and returns again to afterwards to subscriber equipment end.Concrete processing procedure, it is judged that in the resource content of the accessed page be
No comprising embedded outer net resource, if included, then modifying the URL of outer net resource, the process of amendment is mainly
The outer net resource identification got before can be added in the URL of outer net resource.
It should be noted that a corresponding HTML(Hypertext Markup Language of webpage, hypertext mark
Note language) file, when accessing certain webpage, Web server returns to the page resource content of PCEF/TDF and is exactly typically
This html file.Html file is with .htm or .html as suffix name, and the resource content comprised in webpage is all at HTML
Defined in document, for the outer net resource being embedded in a page, this outer net money can be write in html document exactly
The URL in source, so when user clicks on the link of this outer net resource in this page, will provide to outer net according to this URL
Access request initiated by the Web server at place, source, obtains concrete resource content.And in embodiments of the present invention, strategy
Control system (PCEF or TDF as therein in this policy controlling system) after getting the html file of a webpage A,
If the URL of this webpage A is certain specific transactions main application page, then in the embodiment of the present invention, it is possible to from webpage A's
Html file finds out the URL of the embedded outer net resource wherein comprised, then the URL of these outer net resources is carried out
Amendment, namely it is respectively outer net resource identification in the URL interpolation of each outer net resource.URL for each outer net resource adds
After having added outer net resource identification, it is possible to replace the original URL of each outer net resource in html file respectively, preserve it
The most just can return to subscriber equipment.
S104: determine when the URL of the described accessed page comprises described outer net resource identification, then according to described control strategy
Content carries out policy control.
Subscriber equipment is receiving the quilt that policy controlling system (PCEF or TDF as therein in this policy controlling system) returns
After the resource content of accession page, browser just can carry out parsing to resource content and render, and shows the page of correspondence.
During showing the page, the server that browser may be applied to other for embedded some picture resources etc.
Initiate to obtain the request of these picture resources, in order in the page, show this picture.After showing the page, Yong Hushe
Standby can also continue in this page, perform the operations such as clickthrough and initiate new accessing page request.These are clicked
Link may point to Intranet resource, namely another main application page, it is also possible to points to outer net resource.If sensing Intranet
Resource, then the URL of the accessed page that accessing page request is corresponding will be included in the main application page URL of corresponding business
In set, therefore, the control strategy implementation strategy that this policy controlling system just can use this business corresponding accordingly controls.As
Fruit points to outer net resource, then in the operation before will being included in the URL of the accessed page that accessing page request is corresponding
Add outer net resource identification, and can recognize that correspondence be which specific transactions, therefore, this policy controlling system with
Sample can use the control strategy implementation strategy that this specific transactions is corresponding to control accordingly.
Although it should be noted that in step s 103 the URL of each outer net resource embedded in accessed webpage being entered
Go amendment, but the display of accessed webpage can't have been affected.This is because, for embedded each in accessed webpage
For individual outer net resource, usually representing in the form of a link in accessed webpage, what we revised is the equal of this
Plant the URL of target pages corresponding to link, but the content shown in the source web page at this link place is chain of each link
Connecing text, image etc., these information will not change along with the change of the URL of target web.Certainly, at user's point
After having hit the link of certain outer net resource, if subscriber equipment is directly to send request to the Web server of target web,
Then owing to have modified the URL of target web, it is thus possible to can cannot get corresponding resource.But, the present invention implements
In example, after user clicks the link of certain outer net resource, the request accessing target web can first be sent by subscriber equipment
To this policy controlling system (PCEF or TDF as therein in this policy controlling system), one can be carried out at this policy controlling system
Fixed process, it is ensured that subscriber equipment can show target pages normally.Concrete, this policy controlling system is receiving
After one accesses web-page requests, if it find that the URL of the accessed page includes the outer net resource identification pre-set, then may be used
First the outer net resource identification in the URL of the accessed page is removed, concrete to corresponding Web server request the most again
Outer net resource.
Visible, in embodiments of the present invention, owing to outer net resource representation can be also added in the control strategy issued, and
The URL of the outer net resource that can comprise in the application page main to specific transactions modifies, and adds upper outer net resource identification wherein,
And in outer net resource identification, embody the identification information of this specific transactions, so, after receiving accessing page request, as
Fruit finds to be accessed in the URL of the page and includes outer net resource identification, it is possible to use the control strategy of corresponding specific transactions to this
Access request carries out policy control.Therefore, it is possible in the case of there is embedded outer net resource, it is also possible to carry out and main application
The policy control that the page is identical.
In actual applications, the above-mentioned side of the embodiment of the present invention can be realized by a proxy entity in logic
Case.Concrete, outer net resource identification can be the identification information combination of the URL by preset proxy server and specific transactions
URL fragment.Such as, as a example by this specific transactions of Facebook Zero, it is assumed that the URL of proxy server is:
Www.proxyserver.com/forward.action, then outer net resource identification can be following URL fragment:
www.proxyserver.com/forward.action?Src=facebook, it is seen then that this outer net resource identification is to be taken by agency
The URL www.proxyserver.com/forward.action of business device splices with mark src=facebook of specific transactions
?.So, when the URL of outer net resource is modified, it is possible to former by this URL fragment and outer net resource
Beginning, URL spliced, and forms new URL, and new URL is pointed to proxy server.For example, it is assumed that certain main application
Embedded in the page is certain picture resource of outer net, and corresponding HTML code is <img src=
" www.sina.com/sample.GIF "/>, that is, the URL of outer net resource is www.sina.com/sample.GIF,
The most amended URL be exactly can:
www.proxyserver.com/forward.action?src=facebook&des=www.sina.com/sample
.GIF, accordingly, amended HTML code is:
<img src=
“www.proxyserver.com/forward.action?src=facebook&des=www.sina.com/sample.gi
f”/>
So, the browser of subscriber equipment end is after initiating the request of this picture resource of access, and policy controlling system will detect
Go out in the URL of picture resource and include www.proxyserver.com/forward.action?Src=facebook this
URL fragment, accordingly, it is possible to determine that needs are controlled according to the Special controlling strategy that certain specific transactions is customized, enters
And, by this mark of facebook comprised in this fragment, it may be determined that go out these specific transactions and belong to Facebook
Zero, therefore, is controlled according to the control strategy of Facebook Zero service customizing.Then, concrete money is obtained
During source, first access request can be sent to proxy server by PCEF/TDF, proxy server after the requests have been received,
The original URL of outer net resource according to preset rule, can be extracted from URL, then according to this original URL to right
Concrete resource data asked by the Web server answered, and is then returned to this policy controlling system, then by this policy controlling system
Return to subscriber equipment, thus can show the page of correspondence at subscriber equipment end.
In order to be more fully understood that the embodiment of the present invention, below as a example by the communication system using PCC framework, real to the present invention
The policy control method that executing example provides is introduced.See Fig. 2, may comprise steps of:
S201:PCRF issues control and charging policy to PCEF or TDF.In present embodiment, this control and charging
Strategy generally comprises: main application service mark or set of URL close, and for this main application service and this main application service
The control strategy of the business of middle nesting or charging policy.Can be generally referred to as the service package for this main application service.
Set of URL conjunction is a part for Policy content, can close for these set of URL and do special control strategy, such as visit
Ask and limit on service bandwidth, time, place.In addition to this it is possible to by by proxy server URL and should
The URL fragment that the expression information of business combines increases in the control strategy of this service package, in order to provide as outer net
The mark in source, and represent correspondence be which specific transactions.As a example by this service package is for Facebook Zero, can
With by www.proxyserver.com/forward.action?Src=facebook increases to Facebook Zero business
In the control of set meal and charging policy.
S202: user passes through the browser access Facebook page, and access request is sent to PCEF or TDF；
S203:PCEF or TDF sends service request to the Web server of Facebook；
The Web server of S204:Facebook returns the resource content (a corresponding html file) of service response；
S205:PCEF or TDF identifies the URL of the Web page of the Web server return of Facebook by DPI
The set of URL being included in service package closes interior, then, by the content (example from other application services embedded in this page
The picture resource provided such as outer net, video, audio frequency, text etc.) URL be converted to URL corresponding on proxy server.
URL after conversion meets three below condition: 1. the URL after conversion can point at proxy server；2. after conversion
URL in can comprise in service package control with charging policy in for proxy server setting URL fragment；3. act on behalf of
Server can by conversion after URL obtain outer net resource origin url, in order to obtain resource return to PCEF or
The most such as, embedded is picture resource, then can be by code <img src=corresponding in html file
" www.sina.com/sample.GIF "/>, be converted to<img src=
“www.proxyserver.com/forward.action?src=facebook&des=www.sina.com/sample.gi
f”/>.Wherein, www.proxyserver.com/forward.action represents the URL of proxy server,
Src=facebook represents service identification, the origin url of des=www.sina.com/sample.GIF representative picture resource.
So, PCEF or TDF can recognize the need for using Facebook Zero service package according to src=facebook
Control and charging policy, proxy server, can be to corresponding Web according to des=www.sina.com/sample.GIF
Server obtains concrete picture resource.
S206:PCEF or TDF will comprise the facebook page of URL corresponding to amended outer net picture resource
Html file returns to the browser of subscriber equipment, and the browser of subscriber equipment can show facebook page of correspondence
Face；
Outer net picture resource embedded in S207: the terminal browser request Facebook page.Such as in previous example
That picture；
S208:PCEF or TDF sends outer net resource content request to proxy server；
S209: proxy server analysis also obtains this embedded content from other application services (such as original image money
Source) URL, to these other application services server (i.e. source material) send request；
The server returned content response of S210: these other application services；
S211: proxy server returns this content response to PCEF or TDF；
This content response from the server of other application services received is returned to use by S212:PCEF or TDF
Family device navigator；
S213:PCEF or TDF identifies amended resource URL and includes following URL fragment:
www.proxyserver.com/forward.action?Defined in this URL fragment i.e. step S201 of src=facebook(
URL fragment in service package charging policy), therefore, mate Facebook Zero service package, carry out corresponding
Control and the control of charging policy: such as, carry out traffic monitoring, and to OCS(Online Charging System,
Online Charging System) report the flow quota making to be finished and apply for new flow quota.
It should be noted that in actual applications, the outer net resource being embedded in the main application page not only includes that picture provides
Source, it is also possible to include the resources such as audio frequency, video, text, as long as be embedded in current application from other application services
Resource, just may be by the embodiment of the present invention provide mode carry out policy control.Wherein, due to finally need by

" http://www.sina.com/sample.flv "/>, according to the suffix name " flv " of URL it appeared that this is one
Individual video resource, and this form in the terminal cannot normal decoder, then need it is changed, therefore,
Can be able to be with amended URL just:
www.proxyserver.com/forward.action?src=facebook&format=3gp&des=http://www.si
Na.com/sample.flv, it is seen then that for the URL in previous example, adds this letter of format=3gp
Breath.So, when user accesses this video resource, the URL of the accessed resource that PCEF or TDF receives is exactly that this is repaiied
URL after changing, owing to including this information of format=3gp, therefore, receiving the server of other application services
After the resource content returned, need first the form of video to be converted to 3gp, then return again to terminal unit.Close
