Below in conjunction with concrete example, the policy control method of the third-party application that the embodiment of the present invention is recorded is carried out
Explanation.
Example one
This example describes under the SCEF deployment scenario shown in Fig. 2, and in the first side, SCEF is to third party
The overall signing QoS of AS carries out authorization decision, in the second side, PCRF to the IP-CAN session of UE and
In session, data service stream QoS carries out authorization decision, namely in the first side, the second both sides, side grading authorized
Utility cession Establishing process.In the present embodiment, the overall CAMEL-Subscription-Information of third party AS is stored in SCEF.
As it is shown in fig. 7, the policy control under SCEF framework comprises the following steps:
Step S301:UE is attached to network, sets up IP-CAN session.
It is attached to network at UE, during setting up IP-CAN session, sets up between PCEF and PCRF
For strategy and charging control Gx session, if IP-CAN session relates to BBERF, then BBERF with
The gateway control session for policy control is set up between PCRF.
Step S302:UE is mutual with third party AS, initiates Operational Visit.
Step S303: perform specific interaction flow between third party AS and AF.
Third party AS transmission service request, to AF, carries the business of user's request, the business pair of user's request
The QoS answered, can use HTML (Hypertext Markup Language) (HTTP, Hyper Text Transfer Protocol) or
The form of application programming interfaces (API, Application Program Interface) sends service request, industry
Business request can also comprise the consumption (such as application bandwidth, time or flow) of request QoS.
The interface of the transmission service request between third party AS and AF is non-standard interface, right in actual application
Message and the function of this interface do not limit.
Step S304:AF sends QoS request to SCEF.
Such as can send QoS request, in QoS request to use the form of HTTP POST or API message
Carry UE IP, the business information of UE IP, UE request, the QoS information corresponding to business of UE request.
AF is to send QoS request based on the discernible standard interface of SCEF to SCEF, it is thus possible to right
QoS request from third party AS carries out form conversion, screens including to the information in QoS request
And filling.
QoS request may also include application identities and Media Stream describes, and the QoS that the business of UE request is corresponding believes
Breath can comprise QoS level information, such as Business Processing waiting time or the information such as time delay and processing priority；
Preferably, QoS information can comprise the consumption (such as application bandwidth, time or flow) of request QoS.
Step S305:SCEF carries out authorization decision to the overall signing QoS of third party AS.
SCEF is according to the overall CAMEL-Subscription-Information of locally stored third party AS, namely the entirety of third party AS
Predefined QoS (pre-defined QoS) CAMEL-Subscription-Information and the QoS request of third party AS, to the
The overall signing QoS of tripartite AS carries out authorization decision；If authorizing successfully, then perform subsequent step, as
Really authorization decision failure, SCEF can be by authorization failure message informing third party AS.
As it was previously stated, the overall CAMEL-Subscription-Information of third party AS at least include the Business Processing waiting time, time delay,
And the information such as processing priority；The overall CAMEL-Subscription-Information of third party AS can also be third-party application business and
The QoS level instruction of operator negotiation agreement, the concrete mode consulting agreement needs and operator according to realization
Strategy execution.
The overall CAMEL-Subscription-Information of third party AS is stored in SCEF, including at least one of: third party AS
Mark, GBR that MBR, the third party AS that third party AS contracts in advance contracts in advance, third party
The maximum number of user that AS contracts in advance, permission class of business that third party AS contracts in advance and type, and
The QoS level information (including processing priority and the processing delay etc. of signing service in advance) of third party AS.
Preferably, when actual deployment network performs, SCEF carries out the overall signing for third party AS
During the authorization decision of QoS, can realize by the way of following, which kind of mode specifically used can be according to reality
The carrier policy that internet is disposed selects.
1) third party's AS network element, number of users and bandwidth consumption etc. are related to for static state unrelated with multidate information
Parameter authorization (such as third party AS whether contract accessible etc.), the overall signing QoS to third party AS
Authorization decision can complete alternately in the first time after SCEF powers on, and according to authorization cycles update to the 3rd
The authorization decision of the overall signing QoS of side AS, it is to avoid repeat to hold in the service request of each UE processes
The authorization decision of this kind of parameter of row.
2) for signing parameter authorization (the such as third party of non-specific business for single (Per) UE
The maximum number of user that AS allows, it is allowed to access user class etc.), can at UE for the first time and third party AS
AF session establishment during complete the authorization decision of the overall signing QoS to third party AS, and according to
Authorization cycles is updated the authorization decision of the overall signing QoS to third party AS, it is to avoid at each UE
Service request process in repeat the authorization decision of this kind of parameter.
3) for the authorization decision of concrete business of third party AS, rather than the business for UE request is correlated with
Signing parameter authorization decision-making, the permission type of service of such as this third party AS signing and service priority etc.
Time, for the first time and the entirety to third party AS can be completed during the session establishment of SCEF at third party AS
The authorization decision of signing QoS, and it is updated the overall signing QoS to third party AS according to authorization cycles
Authorization decision, it is to avoid repeat the authorization decision of this kind of parameter in the service request of each UE processes.
Step S306:SCEF sends QoS request (such as with Diameter AAR message to PCRF
Form sends), QoS request is carried the business information QoS corresponding with the business that UE ask of UE request and is believed
Breath, and the overall QoS authorization decision information of third party AS.
QoS request also can comprise Internet protocol (IP, the Internet distinguishing SDF for policy control
Protocol) application message such as information and application type, application bandwidth demand, the entirety of third party AS are filtered
The information such as CAMEL-Subscription-Information, the time cycle of request QoS or flow threshold, further authorize certainly for PCRF
Plan makes reference.
Step S307:PCRF returns AAA to SCEF and confirms message.
Step S308:SCEF returns to AF/AS and confirms message (such as HTTP or API message).
Step S309:PCRF, based on the QoS request received, carries out authorization decision to the business of UE request.
The business information of UE request, UE requested service that the third party AS that SCEF transmits provides are corresponding
QoS information, and the overall QoS authorization decision information of third party AS and based on such as network strategy and
The information such as the load status information of current network and user's signing, enter the QoS of the business of UE request
Row authorization decision.
When the IP-CAN session of UE and the QoS of gateway control session are carried out authorization decision, being additionally based upon please
The QoS asked is the service generation PCC rule in the transmission of IP-CAN conversation request, if BBERF exists,
Then PCRF is always according to PCC Rulemaking QoS rule.
Step S310:PCRF provides QoS rule to BBERF.
Step S311:PCRF provides PCC rule to PCEF.
After PCEF installs and executes strategy, return to PCRF and confirm message.
Step S312:PCRF sends (RAR, Re-Auth-Request) message to SCEF, by step
The authorization decision result of the UE requested service QoS that S309 generates notifies to SCEF.
Step S313:SCEF sends API or HTTP PUT message to AF, informs UE requested service
The authorization decision result of QoS.
Step S314:AF returns to SCEF and confirms message.
Step S315:SCEF returns to PCRF and confirms message.
Step S316:AF and third-party particular message, such as report application server to accumulative consumption
Report etc. application related information.
This example is applicable to conventional third party's business, and third party's sponsorship data business.When praising for third party
When helping data service, the AF message that SCEF receives comprises the various information that sponsorship data is relevant, such as, praises
Business is helped to indicate, the information such as sponsor identifies, application provider's mark, preferably can comprise relevant amounts
Threshold value, the information such as charging rate main body.In the message that the PCRF that SCEF receives provides, it will comprise patronage
The information that data are relevant, and optional business consumption report, concrete sponsorship data operation flow can refer to
Correlation technique flow process realizes, because the QoS authorization decision flow process recording the present embodiment does not affect, the most not
Specifically describe.
Example two
This example describes under SCEF deployment scenario, SCEF forward third party AS QoS request to
PCRF, PCRF have unified in the IP-CAN session to third-party overall signing QoS, UE and session
The QoS of data service stream carries out authorization decision, to complete the flow process that utility cession is set up；Wherein, third party
It is local that the overall CAMEL-Subscription-Information of AS is stored in SPR or is predefined in PCRF.
As shown in Figure 8, comprise the following steps:
Step S401:UE is attached to network, sets up IP-CAN session.
In this process, the Gx session controlled for strategy and charging is set up between PCEF and PCRF.
If IP-CAN session relates to BBERF, then set up the net for policy control between BBERF and PCRF
Close and control session.
Step S402:UE is mutual with third party AS, initiates Operational Visit.
Step S403: perform specific interaction flow between third party AS and AF.
Third party AS provides the UE business information of request, and the QoS corresponding to business of request to AF
Information, third party AS sends one and asks to AF, and the information of the business of UE request is carried in this request, with
And the QoS information corresponding to business of request, this request can be sent to use the form of HTTP or API；Excellent
Selection of land, can also comprise the consumptions such as the request application bandwidth of QoS, time and flow in this request.
Step S404:AF sends QoS request (such as HTTP POST or API message) to SCEF,
QoS request is carried information and the UE requested service pair of the business of UE IP, UE ID, UE request
The QoS information answered.
QoS request may also include application identities and Media Stream describes；QoS information can comprise Business Processing and wait
Time or time delay, the information such as processing priority, preferably can also comprise consumption, as asked the application of QoS
Bandwidth, time and flow etc..
Step S405:SCEF carries out processing locality (to be converted to what PCRF can identify to QoS request
Form) and send QoS request by Rx interface to PCRF.
QoS request (can send with the form of Diameter AAR message) is carried the business of UE request
The QoS information corresponding to business of information, UE request；Also can comprise the IP distinguishing SDF for policy control
Application message, application bandwidth demand, the entirety of third party AS such as filtration information and application type predefine QoS
CAMEL-Subscription-Information (namely overall CAMEL-Subscription-Information of third party AS), the time cycle of request QoS or flow threshold
Etc. information, make reference for the further strategic decision-making of PCRF.
SCEF can possess the entirety of third party AS and predefine the mapping function of QoS CAMEL-Subscription-Information, as front
Described, the entirety of third party AS predefines QoS CAMEL-Subscription-Information and at least includes QoS level information, such as business
Processing latency or time delay and processing priority information；The entirety of third party AS predefines QoS and signs
About information can also be mapped as current Rx interface qos parameter；Or the QoS after mapping for SCEF
Rank instruction (such as operator is self-defining or operator and the QoS level of the third Protocol agreement),
Concrete mode is according to realizing needs and carrier policy execution.
Step S406:PCRF returns AAA to SCEF and confirms message.
Step S407:SCEF returns to AF/AS and confirms that message (confirms that message can be with HTTP or API
The form of message sends).
Step S408: if now PCRF is not the most mutual with SPR, then now PCRF needs and SPR
Interact.
PCRF judges according to UE mark if the CAMEL-Subscription-Information of the most not this UE, then send to SPR
Document of contracting is asked, and carries UE mark and PDN mark in this signing document is asked.
Step S409:SPR identifies according to ID and PDN and returns user signing contract information (that is, signing
Document response).
The overall CAMEL-Subscription-Information of third party AS can be stored in SPR, including third party AS mark, third party
GBR, third party AS that MBR, the third party AS that AS contracts in advance contracts in advance contract the most in advance
Permission class of business that large user's number, third party AS contract in advance and type and third party AS are signed in advance
The about QoS level information (such as processing latency or time delay and processing priority etc.) of business.
If sponsorship data business, the most now SPR can provide sponsorship data to connect document and patronage to PCRF
The overall CAMEL-Subscription-Information of business.Sponsorship data connects document and includes the instruction of patronage business, sponsor's mark, application
The information such as provider's mark；Preferably comprise the information such as relevant amounts threshold value, charging rate main body；Sponsor
The project that includes of overall CAMEL-Subscription-Information can refer to the overall CAMEL-Subscription-Information of third party AS of above record.
After step S410:PCRF is to the overall signing OoS authorization decision success of third party AS, based on receipts
The CAMEL-Subscription-Information of the SPR arrived, SCEF transmit third party AS provide UE request business information,
The corresponding QoS information of business of UE request, and the overall CAMEL-Subscription-Information of third party AS, in conjunction with network
The information such as information and user's signing such as the load condition of strategy and current network, the business to UE request
QoS carry out authorization decision.
The QoS that UE carries out IP-CAN session and gateway control session carries out authorization decision, and based on UE
The QoS of requested service is this service generation PCC rule；If BBERF exists, then PCRF is always according to PCC
Rulemaking QoS rule.
In this example, the overall CAMEL-Subscription-Information of third party AS is in addition to being stored in SPR, it is also possible to according to
Carrier policy is self-defined in PCRF this locality, and particular content can include that third party AS identifies, third party AS
The maximum that GBR, the third party AS that MBR, the third party AS contracted in advance contracts in advance contracts in advance
Permission class of business that number of users, third party AS contract in advance and type and third party AS are signed in advance
The about QoS level information such as the processing priority of business and processing delay.
It is pointed out that the QoS of the business to UE request carries out authorization decision, premise is to third party
The overall signing QoS of AS authorizes successfully；In other words, in this step, substantially comprise third party AS
Overall signing QoS carries out authorization decision and the OoS to UE requested service carries out authorization decision the two poles of the earth and awards
Power.
Step S411:PCRF provides QoS rule to BBERF.
Step S412:PCRF provides PCC rule to PCEF, after PCEF installs and executes strategy, to
PCRF returns and confirms message.
Step S413:PCRF sends RAR message to SCEF, by UE requested service QoS authorization decision
Result notifies to SCEF.
Step S414:SCEF sends API or HTTP PUT message to AF, informs UE requested service
QoS authorization decision result.
Step S415:AF returns to SCEF and confirms message.
Step S416:SCEF returns to PCRF and confirms message.
Step S416:AF and third-party particular message, such as report application server to accumulative consumption
Report etc. application related information.
This example is applicable to conventional third party's business, and third party's sponsorship data business.When praising for third party
When helping data service, the AF message that SCEF receives comprises the various information that sponsorship data is relevant, such as, praises
Business is helped to indicate, the information such as sponsor identifies, application provider's mark, preferably comprise relevant amounts threshold value,
The information such as charging rate main body.In the message that the PCRF that SCEF receives provides, it will comprise sponsorship data phase
