Embodiment one
The flow chart of the user redirection method that Fig. 2 provides for the embodiment of the invention one, present embodiment is described from the angle of PCEF, and as shown in Figure 2, the user redirection method of present embodiment comprises:
Step 21, PCEF receives the connection request that establishes a communications link that the user sends, and wherein connection request comprises user ID;
Wherein connection request is initiated by the user, and user ID can be subscriber phone number, fixed telephone number, personal computer Number for access etc. according to the difference of user terminal.
Wherein, PCEF is according to inserting request generation strategy request message, and be specially: PCEF obtains the user ID in the request of access, and user ID is packaged into credit control request (the Credit Control Request that meets Diameter; Abbreviate as: CCR) message, i.e. strategy request message in the step 22.And after generating CCR message, PCEF sends to PCRF by the Gx interface with CCR message, to control to the PCRF request strategy.
Concrete, after PCRF receives the CCR message that PCEF sends, obtain user ID in the CCR message by resolving CCR message, and remove the inquiring user subscribed database according to user ID, obtain the pairing user signing contract information of user ID; Then, PCRF is according to user signing contract information, and for example flow information, duration information, cost information or precedence information etc. are made and are redirected strategy, and will be redirected strategy as Credit Control Answer (Credit Control Answer; Abbreviate as: the CCA) parameter of message sends PCEF by CCA message.Wherein, if PCRF is according to the customer service CAMEL-Subscription-Information, for example flow information, duration information or cost information etc. are formulated when being redirected strategy, also will use information in conjunction with customer service, for example use traffic, duration or cost information etc. are to generate the more targeted and abundanter redirected policy information of content information.
Wherein, comprise the redirect operation indication in the redirected strategy, be used to indicate PCEF that the user is carried out redirect operation; Also comprise the Redirect Server address, be used to indicate PCEF where the user is redirected to.
The user redirection method that present embodiment provides, when the user sends the access request, be redirected strategy by PCEF to the PCRF request, PCRF generates redirected strategy according to user's CAMEL-Subscription-Information, can formulate multiple redirected strategy based on the CAMEL-Subscription-Information that the user enriches, compare based on the redirected of expense with existing, present embodiment can provide redirection function to the user in plurality of application scenes, and realization has improved quality of services for users user's redirect operation.
Concrete, present embodiment provides several instantiation explanations how to formulate redirected strategy according to user signing contract information.For example, formulate redirected strategy based on the flow information in the user signing contract information, concrete: obtain this user's signatory flow as PCRF after, the difference of the flow that uses according to the signatory flow that obtains and active user, generate and be redirected strategy, promptly user regularly (for example every day or weekly, PCRF can be provided with voluntarily) when connecting first, by the user being redirected to the residual flow information of flow prompting interface (being Redirect Server) with the prompting user.Wherein, be redirected the chained address (being equivalent to the Redirect Server address) and the indication of flow redirect operation that also comprise flow prompting interface in the strategy, be used for indication and carry out redirect operation according to flow.
Again for example, formulate redirected strategy based on the duration information in the user signing contract information, concrete: when PCRF obtains this user for the time contracted user, the signatory duration and the user that obtain the user have used duration, and formulate user's redirected strategy according to the difference of two durations, so that when the user regularly connects first, long prompt interface (Redirect Server) is with prompting user's information remaining time when the user is redirected to.In like manner, be redirected the chained address (being equivalent to the Redirect Server address) and the indication of duration redirect operation at long prompt interface when also comprising in the strategy, be used for indication and carry out redirect operation according to duration.
Again for example, formulate redirected strategy based on the authority of user's signing service, concrete: when PCRF obtains this user for the contracted user, obtain user's signing service information, and formulate user's redirected strategy according to the signing service scope, so that when the user carries out service request, if surpass described user's signing service scope, then by the user being redirected to the signing service scope of prompting interface (being Redirect Server) with the prompting user.
Further, PCEF can return connection to the user and confirm response behind the redirected strategy that receives the PCRF transmission in the present embodiment.After the user receives and connects the affirmation response, send the Operational Visit request to PCEF, this moment is as described in the step 24, PCEF can indicate the Redirect Server that the user is redirected to Redirect Server address correspondence according to the redirect operation that is redirected in the strategy when receiving the Operational Visit request of user's transmission.Present embodiment provides the specific implementation of two kinds of described operations of step 24:
A kind of implementation is: PCEF receives the Operational Visit request that the user sends, and when receiving the Operational Visit request, the redirected strategy that inquiry PCRF provides is to obtain redirect operation indication and Redirect Server address; And after obtaining above-mentioned information, indication sends to the user with the Redirect Server address according to redirect operation, for the Redirect Server of user capture Redirect Server address correspondence, finishes redirect operation.
In this method, PCEF offers the user with the Redirect Server address, is redirected on the Redirect Server by user oneself, has guaranteed user ' s right to a certain extent.
Another kind of implementation is: PCEF receives the Operational Visit request that the user sends, and wherein the Operational Visit request comprises the access server address; And when receiving the Operational Visit request, inquiry is redirected strategy to obtain redirect operation indication and Redirect Server address; Then, PCEF replaces with the Redirect Server address with the access server address in the Operational Visit request, and the Operational Visit request after will replacing according to redirect operation indication sends to the Redirect Server of Redirect Server address correspondence, realizes redirected to the user.
In this method, PCEF is when receiving the Operational Visit request, directly indication is redirected to Redirect Server with the user according to redirect operation, compare with first kind of implementation, this method is simpler on operating process, save the process that sends the Redirect Server address between user and the PCEF, saved system resource.
What deserves to be explained is at this, in the present embodiment in the customer service access request except comprising the access server address, also can comprise multiple other information, the for example title of user ID, station address, customer service authority, access service, the supplier of access service etc., because above-mentioned information does not relate to technical solution of the present invention, therefore, present embodiment does not elaborate.
To how use technical solution of the present invention in actual applications by the embodiment explanation below.

Wherein, the Redirect-Server specified server can be HTML (Hypertext Markup Language) (Hyper Transfer Proyocol in the present embodiment; Abbreviate as: HTTP) reset to server or conversation initialized protocol (Session Initiation Protocol; Abbreviate as: SIP) reset to server.The type of the Redirect Server address of Redirect-Server-Address appointment and the Redirect Server address of Redirect-Server-Address appointment, and both combine unique definite Redirect Server.
Wherein, specifically defined following several address styles among the Redirect-Server-Address:
The IPv4 address, its value is set to 0, and the specific address type is the IPv4 form of definition in [IPv4].
The IPv6 address, its value is set to 1, and the specific address type is the IPv6 form of definition in [IPv6].Address format can be the first-selected form (preferred form) or the standby form (alternate form) of definition in [IPv6].Wherein require Redirect Server must support first-selected form, preferably should support standby form simultaneously.
URL(uniform resource locator) (Uniform Resource Locator; Abbreviate as: URL) address, its value is set to 2, and the specific address type is the URL form of definition in [URL].
SIP universal resource identifier (Universal Resource Identifier; Abbreviate as: URI) address, its value is set to 3, and the specific address type is the SIP URI form of definition in [SIP].
Based on above-mentioned AVP value, illustrate to the present invention is based on the concrete principle that policy control realizes the technical scheme that the user is redirected:
The flow chart of the user redirection method that Fig. 3 provides for the embodiment of the invention three, as shown in Figure 3, the method for present embodiment comprises:
Step 31, user terminal is initiated PDP to PCEF and is activated request, and wherein PDP activates in the request and comprises user terminal identification;
Wherein, user terminal identification can be phone number, user identification module (SubscriberIdentity Module; Abbreviate as: SIM card) number or international mobile station equipment identifier (International Mobile Equipment Identity; Abbreviate as: IMEI), network insertion number, user terminal number of registration etc., to activate request be example to initiate PDP in this enforcement, but be not limited thereto, and can also be the request of setting up the IP network meeting.
Concrete, present embodiment is an example with the GPRS network, and then PCEF is GGSN, and then the PDP that sends of user terminal activates request and can send to PCEF with text SMS or the form of the multimedia message gateway interface by GGSN.
Step 32, PCEF resolves this PDP activation request according to the data format of PDP agreement after the PDP that receives the user terminal transmission activates request, obtains user ID wherein; Then, this user ID is encapsulated in the CCR message, and CCR message is sent to PCRF by the Gx interface, comprise also in the CCR message that wherein expression PCEF is redirected the content of strategy to the PCRF request;
Step 33 after PCRF receives CCR message, is resolved CCR message according to the data format of Diameter, obtains user ID wherein and obtains the purpose that PCEF sends CCR message, promptly is redirected strategy to the PCRF request;
Step 34, PCRF obtains user signing contract information according to user ID inquiring user subscribed database (SPR);
Concrete PCRF is undertaken alternately by Sp reference point and SPR, promptly send look-up command to SPR by the SP reference point, and regain lookup result by the Sp reference point, and wherein PCRF carries out mutual technical scheme by Sp reference point and SPR and belongs to prior art, and present embodiment is not described in detail.
Step 35, PCRF generates the redirected strategy of respective user sign according to the user signing contract information that gets access to, and will be redirected strategy and be encapsulated in the CCA message;
Wherein, the information such as situation, User Priority that can comprise type, the user capture business of total duration, total flow, the access network of the access network that the user contracts in the user signing contract information, in order to improve quality, can select the information of outbalance in the user signing contract information as the scene that generates redirection information according to user's actual conditions to user's service.It is example that present embodiment is selected total duration, the total flow of access network, when every day, the user initiated PDP activation request first, the user is redirected to duration or flow prompting interface.Concrete, the AVP value that PCRF is provided with Final-Unit-Action is 1, the chained address of the AVP value of Redirect-Server-Address for Redirect Server is set, http://redirect-server.com for example, and the AVP value that Redirect-Address-Type is set is 2, and other parameters are set, generate each AVP fields such as Final-Unit-Indication, Final-Unit-Action, Redirect-Server, Redirect-Server-Address and Redirect-Address-Type according to the predefined form of present embodiment.
Add above-mentioned AVP field in CCA message by the mode of calling addAvp, promptly issue to PCEF and be redirected strategy by CCA message.
Step 36, PCRF returns CCA message by the Gx interface to PCEF, wherein carries the AVP value that is used to finish redirect operation of the pre-defined form of PCRF generation in the CCA message;
Step 37 after PCEF receives CCA message, is resolved CCA message according to the data format of Diameter, obtains each AVP value of wherein carrying, and promptly is redirected strategy, and storage should be redirected strategy; Then, execution in step 38 is returned the PDP activation response that corresponding PDP activates request to user terminal, and expression connects sets up.
Step 38, PCEF returns the PDP activation response that corresponding PDP activates request to user terminal;
Step 39, user terminal sends the Operational Visit request of visiting first server to PCEF, wherein comprises the address of first server in the Operational Visit request;
For example, the IMSI number is that 460123412345678 user terminal need be inquired about a business, this business is on first server, then user terminal sends the URL1 of first server to PCEF, this user terminal is inserted first server of this URL1 correspondence by PCEF, user terminal obtains the business that will inquire about, the operation when aforesaid operations receives the Operational Visit request that user terminal sends for existing PCEF.But, in the present embodiment, PCEF is when receiving the Operational Visit request of user terminal transmission, need remove to inquire about the redirected strategy that obtains from PCRF, according to the value of Final-Unit-Action, Redirect-Server-Address etc. wherein, getting access to needs for example URL2 of execution redirect operation and Redirect Server address, and execution in step 38 then;
Step 40, PCEF sends to user terminal with the Redirect Server address, need carry out redirect operation with indicating user terminal, promptly visits Redirect Server;
Concrete, PCEF sends to user terminal with URL2, and user terminal receives URL2.
User terminal is initiated connection request to Redirect Server in the HTTP mode by URL2, and waits for the response that the reception redirect services is returned.
Wherein, under Session Initiation Protocol, redirect services can be returned response message to user terminal by HTTP 200OK message.
In the present embodiment, connect between user terminal and the Redirect Server and follow-up interactive operation belongs to prior art, present embodiment is discussed no longer in detail.
