Description

Service quality update method and the system of a kind of strategy and charging regulation

Technical field

The present invention relates to strategy and charging control technology in the wireless communication system, relate in particular to a kind of service quality update method and system of the middle strategy of grouping system (EPS, Evolved Packet System) with charging regulation of evolution.

Background technology

Fig. 1 is 3GPP evolved packet system structural representation, as shown in Figure 1,3GPP evolved packet system (EPS, Evolved Packet System) by the universal mobile telecommunications system land radio access web (E-UTRAN of evolution, Evolved Universal Terrestrial Radio Access Network), mobile management unit (MME, Mobility Management Entity), gateway (S-GW, Serving Gateway), grouped data network gateway (PDN GW or P-GW, Packet Data Network Gateway), home subscriber server (HSS, Home Subscriber Server), authentication and authorization charging (the AAA of 3GPP, Authentication, Authorization and Accounting) server, "Policy and Charging Rules Function entity (PCRF, Policy and Charging Rules Function) and other support node form.

Wherein, MME is used for the chain of command related works such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, forwarding data between E-UTRAN and P-GW, and be used for the pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and PDN, is used for the access of PDN and the function such as forwarding data between EPS and PDN.

EPS supports the intercommunication with non-3 GPP system.Pass through S2a, S2b, S2c Interface realization with the intercommunication of non-3 GPP system, P-GW is as the anchor point between 3GPP system and the non-3 GPP system.Wherein, non-3 GPP system is divided into the non-3GPP connecting system of trusted and trustless non-3GPP connecting system.The non-3GPP connecting system of trusted can directly be connected with P-GW by the S2a interface; Trustless non-3GPP connecting system need link to each other with P-GW through the packet data gateway (ePDG, Evolved Packet Data Gateway) of evolution, is the S2b interface between ePDG and the P-GW.The S2c interface provides subscriber equipment (UE, User Equipment) with P-GW between relevant control and the mobility support of user's face, the mobility management protocol of supporting is for supporting the mobile IP v 6 (DSMIPv6, Moblie IPv6 support for dual stack Hosts and Routers) of two stacks.

The EPS system introduces policy and charging control (PCC, Policy and Charging Control) functional framework user's Operational Visit is carried out dynamic policy and charging control.Fig. 2 is the PCC structural representation under the non-roaming scene among the Rel-8, as shown in Figure 2, Application Function (AF, Application Function) is used for providing the access point of service application, and the employed Internet resources of these service application need to carry out dynamic policy control.When service surface was carried out parameter negotiation, AF passed to PCRF with related service information.If these business information are tactful consistent with PCRF's, then PCRF accepts this negotiation; Otherwise PCRF refuses this negotiation, and provides the acceptable service parameter of PCRF when feedback.Subsequently, AF can return to these parameters subscriber equipment (UE, User Equipment).Wherein, the interface between AF and the PCRF is Rx interface.

PCRF is the core of PCC, is responsible for the formulation of strategic decision-making and charging regulation.PCRF provides the network control rule of service based data flow, these network controls comprise the charging regulation etc. of detection, gate (Gating Control), service quality (QoS, Quality of Service) control and the data flow-based of business data flow.PCRF sends to strategy and charging execution function entity (PCEF, Policy and Control Enforcement Function) execution with strategy and the charging regulation of its formulation; Simultaneously, PCRF needs also to guarantee that these rules are consistent with user's CAMEL-Subscription-Information.PCRF generates strategy and the foundation of charging regulation comprises: from AF obtain with the information of traffic aided, from user-subscribed database (SPR, Subscription Profile Repository) obtain the CAMEL-Subscription-Information relevant with user policy, billing control, obtain from PCEF by the Gx interface with the information of carrying network of relation.

PCEF is usually located in the gateway (GW, Gate-Way), carries out strategy and the charging regulation that PCRF formulates at loading end.Business datum flow filter in the rule that PCEF sends according to PCRF detects business data flow, and then these business data flows are carried out strategy and the charging regulation that PCRF formulates.When carrying was set up, the rule that PCEF sends according to PCRF was carried out the QoS mandate, and carried out gate control according to the execution of AF.Simultaneously, PCEF reports event on the bearer network according to the Event triggered that PCRF subscribes to.According to the charging regulation that PCRF sends, PCEF carries out corresponding service data flow charge operation, and charging both can be online charging, also can be offline charging.If online charging, then PCEF needs and Online Charging System (OCS, Online Charging System) carry out credit management together.During offline charging, the charge information of exchange correlation between PCEF and the off-line accounting system (OFCS, Offline Charging System).Interface between PCEF and the PCRF is the Gx interface, and the interface between the OCS is the Gy interface, and the interface between the OFCS is the Gz interface.PCEF generally is positioned on the gateway of network, grouped data network gateway (PDN-GW), GPRS (GPRS such as EPS, General Packet Radio Service,) in GGSN (GGSN) and interconnected wireless network local area network (LAN) (I-WLAN, Interworking WLAN,) in packet data gateway (PDG, Packet Data Gateway).

Bearing binding and event reporting function entity (BBERF, Bearer Binding and Event Reporting Function) are usually located in the Access Network gateway (Access Network Gateway).As adopting proxy mobile internet protocol version 6 (PMIPv6 between EPS, gateway S-GW and the P-GW when subscriber equipment accesses by E-UTRAN, Proxy Mobile Internet Protocol version 6) during agreement, just there is BBERF among the S-GW.When subscriber equipment accessed by the trusted non-3 GPP access network, also there was BBERF in the trusted non-3 GPP access network Central Shanxi Plain.

SPR has stored the user policy, billing control and subscription information relevant with policy control and charging.Interface between SPR and the PCRF is the Sp interface.

Online Charging System (OCS, Online Charging System) and PCEF carry out the control and management of user credit under the online charging mode together.

Off-line accounting system (OFCS, Offline Charging System) is finished billing operation under the offline charging mode with PCEF.

Above PCC framework has been realized UE is packet data network (Packet Data Network of access by each functional entity, referred to as PDN) IP that sets up connects the policy and charging control of Access Network (IP Connectivity Access Network is referred to as IP-CAN) session.The policy and charging control information of an IP-CAN session is only determined by a PCRF.

In the prior art, after UE was established to the IP-CAN session of certain PDN, network for the Internet resources that its business provides transfer of data to need, can as required be changed its QoS in the business procedure by the QoS of corresponding mandate.Professional for the IMS class, then AF will provide new QoS information to PCRF, and PCRF initiates the modification process of IP-CAN session.PCRF is in conjunction with QoS and the corresponding subscription data of SPR/UDC of the new request of AF, new PCC/QoS rule is authorized and issued to bottom-layer network bearing resource information etc. again to PCEF/BBERF, PCEF/BBERF upgrades respective rule and revises bearing resource, for this business provides new QoS.Professional for non-IMS class, operator can come on-premise network according to self-demand, and self-defined non-IMS class business platform and data center trigger its PCRF initiation IP-CAN session modification flow process by self defined interface and change QoS.Own business platform does not provide if such business is not operator, and then operator can sign proprietary protocol with such service provider, comes to trigger its PCRF initiation IP-CAN session modification flow process by self defined interface and changes QoS.

Mobile operator need to provide for different equipment growing miscellaneous service to process at present simultaneously, and these business may come from own data center of operator, also may be the third party's market demand provider outside the domain of operator.Therefore at present operator reaches proprietary protocol with third party's market demand provider separately and supports the mode of privately owned function and non-3GPP interface to bring the frequent upgrading of carrier network and the policy management mechanisms of complicated confusion.Therefore, realize that mobile operator is that unified 3GPP interface is used in different market demand provider intercommunications, supports the function of this class interworking scenarios at aspects such as authentication, mandate, strategy, charging, mobility and conversation continuities to become the current necessary problem that solves.

Operator can and the certain applications service provider between set up cooperative relationship, for user's applied business provides good service quality and uses and experience, but, the value volume and range of product of network third party application provider is more and more at present, and operator can not accomplish and all application providers possess the business collaboration relation.Therefore, operator needs to possess the independent ability that the needed service quality of applied business is provided for the contracted user of this network under this scene, can promote and reduction service quality according to customer requirements, and can make a strategic decision whether this high quality-of-service is carried out charged extra by user intention.For example, the contracted user A of certain MNO Y of operator, at the business of using certain X of third party application provider to provide (for example online film), because MNO Y and X do not have cooperative relationship, therefore should business use the service quality of the non-assured bandwidth that default bearing provides; In professional use procedure, it is relatively poor to the Y of operator initiation request that user A feels that the user experiences, this professional service quality of requirement lifting, and then the Y of operator need to revise the IP-CAN session of this current UE, promotes corresponding QOS; Simultaneously because high quality-of-service needs charged extra, be necessary to notify the user whether be satisfied with after this liftings service quality and be ready to pay for this reason, after obtaining the user and confirming permission, operator could additionally collect the charges for the lifting of this service quality.Yet, in the existing network technology, do not have support to the processing scheme of lifting and the affirmation of such service quality in existing UE and the flow through a network.

Summary of the invention

Below by specific embodiment explanation this programme.

Embodiment one

As shown in Figure 4, present embodiment has been introduced the Trigger Function of this programme on the framework basis of Fig. 2, the interface that has increased UE and Trigger Function newly (is the interface of UE and application function herein, can adopt http agreement or other application layer signaling), also increased the interface Rx ' (the similar Rx interface of this Rx ' can adopt Diameter communication) of Trigger Function and PCRF newly.

The UE that present embodiment is described accesses the 3GPP network under non-roaming scene, use the business that does not have the third party application service provider of cooperative relationship with operator.Third party's application that operator is responsible for UE provides transfer resource, and can adjust service quality and notice UE affirmation according to the demand of UE, and as shown in Figure 5, service quality is upgraded and the method for affirmation specifically comprises the steps:

Step 501:UE is attached to belonging area network, sets up radio bearer and creates the IP-CAN session.

Step 502:UE logs in and successful access Non-IMS AS, and non-IMS AS provides applied business for UE.Can use http protocol and application layer signaling when wherein, UE communicates by letter with Non-IMS AS.

Step 503:Non-IMS AS and PCRF carry out the PCC flow process.

Non-IMS AS initiates the request of Rx session establishment to PCRF, portability UE ID/IP wherein, traffic ID/application ID, and data flow relevant information.PCRF obtains signatory AS information to SPR/UDC, formulates and issue the PCC rule to PCEF, sets up the related data carrying.

Because this AS and operator be cooperation not, authorizing QoS is default bearing QoS; And for the AS that does not have cooperation, the QoS information of this Rx mouth and PCRF and business information transmission are optional step.

Step 504: finish the establishment of the required carrying of this business.

Concrete, PCRF is according to AS, and SPR/UDC, the client such as PGW hold the relevant information that sends to formulate the PCC/QoS rule, and are issued to PCEF/BBERF; PCEF/BBERF installs and carries out dependency rule, finishes bearing binding, if the coupling carrying does not then issue the request of foundation of carrying, creates carrying; When PCRF issues rule, also may carry relevant event trigger, and consumption monitoring threshold value, the out of Memory such as monitoring keyword; PCEF arranges and carries out dependent event report and consumption monitoring function after receiving information.

Step 505: service bearer creates and finishes, and network is by authorizing QoS that the downlink transfer of this business datum is provided for UE.

Step 506: in the business procedure, that UE lookup service quality Q oS or user experience is dissatisfied (for example, causing owing to mobility or network condition cause the factors such as the unstable or bandwidth of data stream transmitting is too low), and UE initiates QoS to Trigger Function and promotes request.

Wherein, QoS promotes portability UEIP/ID in the request, and preferential flow is processed indication/QoS, and traffic flow information, can also carry traffic ID/application ID in the situation of needs.

Wherein, the communication protocol between UE and Trigger Function is not construed as limiting, and http or application layer signaling all can realize.

Step 507: after Trigger Function received that the QoS of UE promotes request, the service/application of related UE Id/IP and required lifting QoS sent to PCRF and sends QoS lifting request, and the request initiation session revises to promote the QoS of corresponding session.

This QoS promotes portability UEIP/ID in the request, and preferential flow is processed indication/QoS, and traffic flow information, can also carry traffic ID/application ID in the situation of needs.

After step 508:PCRF receives the request message of Trigger Function, inquiry SPR/UDC described user whether contracted high preferential flow process (inquiring user whether contracted mode that high preferential flow processes also can or use by the employed business of inquiring user the high preferential flow of whether having contracted process realize), if so, then according to request initiation session modification process.

PCRF also formulates the PCC rule that issues after the renewal to PCEF/BBERF, and the orADC rule is given TDF.PCEF/BBERF/TDF upgrades the PCC/QoS/ADC rule, revises or newly-built carrying, and the QoS after execution promotes and the binding of relevant bearer, and send response message to PCRF, the Feedback Rule execution result.

Step 509:PCRF returns and promotes QoS modification response message (CCA) to Trigger Function, and whether notice QoS revises and be accepted, and is rejected if QoS revises, and carries the related causes value.

Step 510: after promoting the QoS success, Trigger Function sends to UE and promotes QoS affirmation request message, requires the QoS after the user is confirmed whether satisfied the renewal.

After step 511:UE receives the affirmation message of this Trigger Function, if satisfied and be ready to pay the expense that preferential flow is processed to upgrading business data flow after (for example promoting), then this message is confirmed that UE will send to acknowledge message to this Trigger Function.This Trigger Function returns alternatively and confirms response message to PCRF after receiving the affirmation response of UE, and operator will continue to provide the QoS after promoting (for example, proceed preferential flow and process, high priority or high bandwidth resource are provided) to this business.If UE to the service quality of the business data flow after promoting or the user experiences dissatisfied and or the outer priority treatment expense of amount paid of being unwilling, then the user does not confirm (not returning response message) to this affirmation request or returns negative acknowledgement message to this Trigger Function (if namely the user disagrees with that carrying out new service quality provides this business but the affirmation of not answering in the negative answer, then terminal equipment makes up alternatively negative acknowledgement message according to operator's demand and sends to Trigger Function).

Wherein, if the user does not confirm that then terminal equipment may make up Negative Acknowledgement and return to network, distinguish the user during the technology of being convenient to realizes and do not send and confirm and abnormal case that acknowledge message is lost, but concrete the processing according to carrier network realized processing.

In the such scheme, Trigger Function can arrange QoS and promote timer Timer1 (the Timer1 term of validity should be able to guarantee that IP-CAN session modification that normal PCRF initiates upgrades QoS and is disposed and provides applied business by new QoS for UE) in step 506, overtime at the PCRFCCA acknowledge message and the Timer1 that receive step 509, send the affirmation request message to UE.

Trigger Function also can directly trigger the affirmation message to UE after step 507, message notifying user (this time interval can guarantee effectively that IP-CAN session modification that PCRF initiates upgrades QoS and is disposed and provides applied business by new QoS for UE) within certain time interval processes this preferential flow and confirms, and does not need timer1; Specifically arrange according to realizing, present embodiment is not specifically limited.

Trigger Function is opened the user and is confirmed timer Timer2 after can also sending in step 510 and promoting QoS affirmation request message.

Step 511a: if Trigger Function at the appointed time (for example timer2 duration) do not receive user's affirmation receipt message, or received user's affirmation refuse information, then will send the QoS request of upgrading (for example, reducing the QoS request) to PCRF;

After step 511b:PCRF receives the reduction QoS request message of Trigger Function, in conjunction with CAMEL-Subscription-Information and local policy (for example user confirm to receive the Preview timer of updateQoS is overtime then need to reply original QoS), initiate IP-CAN/GWcontrol/TDF session modification flow process, upgrade relevant PCC/QoS/ADC rule, recover the former QoS of this business;

Step 511c: after the QoS Recovery processing is finished or promote the QoS acknowledging time overtime after, network will return to the QoS of UE request before promoting to the processing of this business data flow.

Wherein, the QoS fallback mechanism is not in the limited range of this programme, can adopt for example rollback time of the mechanism of the timer between network element processing session modification, can locally store update QoS before, carry QoS information before this when perhaps Trigger node sends downgrade QoS request message, perhaps portably use acquiescence QoS indication etc. in the request message.

In the said method, step 510 is optional steps.Can also adopt terminal self to trigger the mode that updating service quality is confirmed request.

In the above flow process, if Trigger Function and PCRF are integrated, then with the processing as internal interface alternately of PCRF.Between all trigger function and the PCRF all is that built-in function realizes alternately.PCRF carries out modification, renewal and the affirmation service quality of IP-CAN session according to the triggering of described Trigger Function.

In the above flow process except policy control, also there is charging relevant treatment flow process, after for example upgrading QoS, may issue new charging keyword (corresponding new charging rate) in the new PCC rule, may exist the network elements such as PCRF, PCEF/BBERF/TDF and charging network element OCS/OFCS and other charge system alternately; This section processes within this programme description is enclosed, is not described further.

Above step 501-511 is the handling process of non-roaming scene, in the professional use procedure, as shown in Figure 6, if UE roams into visited place (roaming ownership place route scene), ownership place PCRF needs notification triggers function UE that roaming has occured, if then also need the UE to reaffirm whether to need to keep high QoS/ high priority flows to process (to process if the user confirms the high QoS of this business for having promoted QoS before this, then may need the outer high priority flows disposal cost of amount paid), if the user confirms that then the visited place is still for this UE provides high QoS, if the user does not confirm or Negative Acknowledgement then will adopt acquiescence QoS that this business is provided in the visited place; As shown in Figure 7, concrete steps are as follows:

Step 512:HPCRF knows that roaming has occured UE, send QoS and confirm that indication is to Trigger Function (for example RAR message), notify the UE roaming, and the affirmation message that the indication Trigger Function sends the preferential flow processing asks UE to be confirmed whether will continue to use the QoS Business Stream to process in the visited place to UE;

Wherein, portability is confirmed indication, UEID/IP, QoS in this message, and may have other business information, traffic flow information for example, traffic ID/application ID etc.

Step 513: Trigger Function sends the indication request message of confirming response message (for example RAA) answer HPCRF.

Step 514: Trigger Function sends the affirmation request message that preferential flow is processed high QoS to UE, the requirement user is confirmed whether to keep high QoS stream and processes, if return sure affirmation message (the preferential flow processing provides extra rate to confirm to need for this reason by the high QoS of reservation); If disagree with the preferential flow disposal cost that amount paid is outer, then return negative affirmation or do not confirm (if the user does not confirm, then terminal equipment may make up Negative Acknowledgement and return to network, distinguish the user during the technology of being convenient to realizes and do not send and confirm and abnormal case that acknowledge message is lost, but concrete the processing according to carrier network realized processing); This handling process, Trigger Function can arrange the user and confirm timer Timer3 when send confirming request, if if timerout does not receive that yet positive acknowledgement then initiates to reduce the QoS handling process);

After step 515:UE receives the affirmation message of this Trigger Function, if want to keep high QoS and be ready to pay the expense that preferential flow is processed, then this message is confirmed that UE will send to acknowledge message to this Trigger Function.This Trigger Function returns alternatively and confirms response message to PCRF after receiving the affirmation response of UE, and operator will continue to provide high QoS (for example, proceed preferential flow and process, high priority or high bandwidth resource are provided) to this business.

The outer priority treatment expense of amount paid if UE is unwilling and do not want to use high preferential flow processing/high QoS, then the user (not returning response message) do not confirmed in this affirmation request or return negative acknowledgement message to this Trigger Function (if namely the user disagrees with and provides the high QoS of this business but the affirmation of not answering in the negative answer, then terminal equipment makes up alternatively negative acknowledgement message according to operator's demand and sends to Trigger Function), execution in step 515a-c.

Step 515a: if Trigger Function at the appointed time (for example timer3 duration) do not receive user's affirmation receipt message, or received user's affirmation refuse information, then will send the QoS request of upgrading (for example, reducing QoS) to PCRF;

After step 515b:HPCRF receives the reduction QoS request message of Trigger Function, in conjunction with CAMEL-Subscription-Information and local policy (for example the user confirms that the timer expiry that keeps high QoS then needs to reduce QoS), initiate IP-CAN/GWcontrol/TDF session modification flow process, upgrade relevant PCC/QoS/ADC rule, recover the acquiescence QoS of this business;

Step 515c: network returns to acquiescence QoS to the processing of this business data flow, issues this business data flow by default bearing QoS.

In the description with embodiment, roaming confirms that the default treatment of notice processes for low QoS, and namely the user does not confirm or QoS (default bearing provides this business) then falls in Negative Acknowledgement; The user returns positive acknowledgement and then continues to keep high priority to process.The default treatment mode of actual treatment can also be to be defaulted as high priority flows to process (i.e. the rear user of roaming does not confirm or positive acknowledgement adopts high priority that this business is provided), falls QoS (providing QoS for this business with default bearing) if the user provides Negative Acknowledgement.Be not construed as limiting for the default treatment mode this programme after the concrete roaming.

Timer among the above embodiment, for example the timer1 of Trigger Function and timer2 can be same timer.Specifically according to realizing requirement, this programme is not done restriction.

Existing techniques in realizing is deferred in the S9 session of concrete ownership place and roaming place in the above flow process; In addition, the scene of the local access of roaming, Notification Validation and QoS modification process are processed the same, and this specification is not repeated in this description.

More than the deployment of roaming is the ownership place network element based on trigger function, trigger function and ownership place PCRF, and UE is mutual.Real network is disposed also can be UE and visited place trigger function direct interaction, and then visited place trigger function and visited place VPCRF are mutual, the information of VPCRF forward pass trigger function depends on specifically that to HPCRF operator disposes with roaming agreement.

Through above-mentioned flow process, can realize that resource when operator provides non-cooperation third party application provider professional for user UE distributes and the policy control processing such as renewals; The user can promote or reduction service quality/user's experience according to self-demand, and change operator is the corresponding service tariff rate of consumption of natural resource that this business transmits;

Embodiment two

Fig. 8 is mutual a kind of introducing universal guiding structure (Generic Bootstrapping Architecture is referred to as the GBA) scheme for current solution mobile operator and third party application provider; Except EPS network and PCC framework, introduced GBA as authentication and the authentication of mobile operator to third party application provider, coming provides related application professional for UE.(the Bootstrapping Server Function of guide service function among the figure, referred to as BSF) for using the functional entity in the net of discussing, the all user securitysettingups (GUSS) of GBA all are stored among the HSS, BSF by and HSS between interface (Zh) obtain user security information and authentication information.Between BSF and UE, produce a session key (Ks) by authentication mechanism between UE and the BSF; network application function (Net Application Function; referred to as NAF) responsible Service control; can obtain this session key from BSF; in this way; NAF and UE just can have a shared key, and this shared key can provide safeguard protection for application subsequently, particularly authentication UE and NAF when utility cession begins.Therefore operator can finish relevant authentication and authentication, for the contracted user provides the third party applied business.

As shown in Figure 9, introduced the Trigger Function function of this programme at Fig. 8 based on the non-roaming network configuration of GBA basis, and the interface that has increased UE and Trigger Function newly (is the interface of UE and application function here, can adopt http agreement or other application layer signaling), increased the interface (the Rx ' here is similar Rx interface, can adopt Diameter communication) of Trigger Function and PCRF newly.This Trigger Function can independently be disposed, or is integrated in other network element for newly-increased logic function; Support and the application layer communication of UE, communicate by letter with the diameter of PCRF.

The UE that present embodiment is described is under non-roaming scene, and access 3GPP network uses the business that does not have the third party application service provider of cooperative relationship with operator.Operator is responsible for UE and third party application provider carries out authentication and transfer resource distributes, and adjusts service quality according to the demand of UE, and needs notice UE to confirm, as shown in figure 10, specifically comprises the steps:

Step 1001:UE is attached to belonging area network, sets up radio bearer and creates the IP-CAN session;

Step 1002:UE access Non-IMS AS/NAF, the bootstrapping mode of employing GBA, UE sends registration request to BSF, carries UEID; BSF obtains CAMEL-Subscription-Information and authentication vector to HSS, and BSF finishes the authentication to UE, generates Ks and B-TID, and B-TID is returned to UE, and UE sends application request to NAF/Non-IMS AS, carries B-TID; NAFNon-IMS AS utilizes this BTID to initiate authentication request to BSF, and the backward UE of success returns response.UE and Non-IMS AS set up secured session;

Step 1003:NAF/Non-IMS AS initiates the request of Rx session establishment to PCRF, carries UE ID/IP, traffic ID/application ID, and the data flow relevant information is to PCRF.PCRF obtains signatory AS information to SPR/UDC, formulates and issue PCC rule to PCEF, sets up the related data carrying.Because this AS and operator be cooperation not, authorizing QoS is default bearing QoS; And for the AS that does not have cooperation, the QoS information of this Rx mouth and PCRF and business information transmission are optional step;

Step 1004: finish the establishment of the required carrying of this business; PCRF is according to Non-IMS AS, and SPR/UDC, the client such as PGW hold the relevant information that sends to formulate the PCC/QoS rule, and are issued to PCEF/BBERF; PCEF/BBERF installs and carries out dependency rule, finishes bearing binding, if the coupling carrying does not then issue the request of foundation of carrying, creates carrying; When PCRF issues rule, also may carry relevant event trigger, and consumption monitoring threshold value, the out of Memory such as monitoring keyword; PCEF arranges and carries out dependent event report and consumption monitoring function after receiving information;

Step 1005: this service bearer creates and finishes, and network is by authorizing QoS that the downlink transfer of this business datum is provided for UE;

Step 1006-1011/1015c: in the business procedure, that UE lookup service quality Q oS or user experience is dissatisfied (for example, because mobility or network condition cause the unstable or bandwidth of data stream transmitting too low etc.), and UE initiates to promote the QoS request to operator; This request process and operator ask to upgrade QoS according to the user and send acknowledge message to the user, according to the user confirm to continue or the relevant treatment of adjusting QoS with step 506-515c.

Embodiment three

Figure 11 is the scheme of introducing GBA and OpenID framework for the mutual another kind of current solution mobile operator and third party application provider; Open ID is the solution that realizes the whole network unified certification: when website of supporting Open ID of terminal use UE login, be relying party (Relying Party, referred to as RP) time, from carry out user's login mode different (these terminal uses perhaps do not register in this website) in this website, this user selection login this website in the mode of Open ID.Open ID be this user in another website, i.e. account number provider (OpenID Provider is referred to as OP), a URL(uniform resource locator) of registration (Uniform Resource Locator is referred to as URL).RP will remove to find OP according to the Open ID that the user provides, and then asks this OP that this user identity is carried out authentication.OP can require the user to login the OP certification page and carry out authentication after receiving the RP request, and after the authentication, OP can remind this user whether to allow the external website authentication.After the user agreed, OP returned to relying party RP with authenticating result; The OP authentication has here adopted the bootmode of GBA, and OP is equivalent to the NAF in the GBA framework.

Among Figure 12 in the Trigger Function function of having introduced this programme based on OpenID and the GBA network configuration basis of Figure 11, and the interface that has increased UE and Trigger Function newly (is the interface of UE and application function here, can adopt http agreement or other application layer signaling), increased the interface (the Rx ' here is similar Rx interface, can adopt Diameter communication) of Trigger Function and PCRF newly.This Trigger Function can independently be disposed, or is integrated in other network element for newly-increased logic function; Support and the application layer communication of UE, communicate by letter with the diameter of PCRF.

As shown in figure 13, specifically comprise the steps:

Step 1301:UE is attached to belonging area network, sets up radio bearer and creates the IP-CAN session.

Step 1302:UE request login RP website (third party application provider) has been selected to login in Open ID mode; RP passes through OP is found in the standardization of user's Open ID, sets up escape way with OP and is used for transmission information (for example RP request OP carries out authentication to user identity); RP returns to the terminal use with the login interface of Open Id, or redirects the user to OP; The user logins OP, and OP is to subscription authentication, and the request user carries out login authentication (having adopted the GBA authentication mode here); Then UE sends registration request to BSF, is with UEID; BSF obtains CAMEL-Subscription-Information and authentication vector to HSS, and BSF finishes the authentication to UE, generates Ks and B-TID, and B-TID is returned to UE, and UE sends application request to NAF/OP, carries B-TID; NAF/OP utilizes this BTID to initiate authentication request to BSF, and the backward UE of success returns response.UE and NAF/OP set up secured session; OP returns to RP with authenticating result, and RP analyzes the result of OP, then returns subscription authentication successfully as the user is legal, can use the RP service; Finish thus authentication and the authentication of UE and RP;

Step 1303:RP/Non-IMS AS initiates the request of Rx session establishment to PCRF, carries UE ID/IP, Service ID/application ID, and flow information relevant information is to PCRF.PCRF obtains signatory AS information to SPR/UDC, formulates and issue PCC rule to PCEF, sets up the related data carrying.Because this AS and operator be cooperation not, authorizing QoS is default bearing QoS; And for the AS that does not have cooperation, the QoS information of this Rx mouth and PCRF and business information transmission are optional step;

Step 1304: finish the establishment of the required carrying of this business; PCRF is according to Non-IMS AS, and SPR/UDC, the client such as PGW hold the relevant information that sends to formulate the PCC/QoS rule, and are issued to PCEF/BBERF; PCEF/BBERF installs and carries out dependency rule, finishes bearing binding, if the coupling carrying does not then issue the request of foundation of carrying, creates carrying; When PCRF issues rule, also may carry relevant event trigger, and consumption monitoring threshold value, the out of Memory such as monitoring keyword; PCEF arranges and carries out dependent event report and consumption monitoring function after receiving information;

Step 1305: this service bearer creates and finishes, and network is by authorizing QoS that the downlink transfer of this business datum is provided for UE;

Step 1306-1314/1315c: in the business procedure, that UE lookup service quality Q oS or user experience is dissatisfied (for example, because mobility or network condition cause the unstable or bandwidth of data stream transmitting too low etc.), and UE initiates to promote the QoS request to operator.This request process and operator ask to upgrade QoS and send acknowledge message to the user according to the user, according to the user confirm to continue or the relevant treatment of adjusting QoS with step 506-515c.

Embodiment four

As shown in figure 14, present embodiment strengthens PCRF on the framework basis of Fig. 2 and possesses Trigger Function, has increased the interface (can adopt http agreement or other application layer signaling herein) of UE and PCRF newly.

The UE that present embodiment is described accesses the 3GPP network under non-roaming scene, use the business that does not have the third party application service provider of cooperative relationship with operator.Third party's application that operator is responsible for UE provides transfer resource, and can adjust service quality and notice UE affirmation according to the demand of UE, and as shown in figure 15, service quality is upgraded and the method for affirmation specifically comprises the steps:

Step 1501:UE is attached to belonging area network, sets up radio bearer and creates the IP-CAN session.

Step 1502:UE logs in and successful access Non-IMS AS, and non-IMS AS provides applied business for UE.Can use http protocol and application layer signaling when wherein, UE communicates by letter with Non-IMS AS.

Step 1503:Non-IMS AS and PCRF carry out the PCC flow process.

Step 1504: finish the establishment of the required carrying of this business.

Step 1505: service bearer creates and finishes, and network is by authorizing QoS that the downlink transfer of this business datum is provided for UE.

Step 1506: in the business procedure, UE lookup service quality Q oS or user experience dissatisfied (for example, cause owing to mobility or network condition cause the factors such as the unstable or bandwidth of data stream transmitting is too low), UE initiates QoS to the PCRF that strengthens Trigger Function and promotes request.

Wherein, the communication protocol between UE and PCRF is not construed as limiting, and http or application layer signaling all can realize.

After step 1507:PCRF receives the request message of UE, inquiry SPR/UDC described user whether contracted high preferential flow process (inquiring user whether contracted mode that high preferential flow processes also can or use by the employed business of inquiring user the high preferential flow of whether having contracted process realize), if so, then according to request initiation session modification process.

Step 1508:PCRF returns and promotes QoS modification response message to UE, and whether notice QoS revises and be accepted, and is rejected if QoS revises, and carries the related causes value.

Step 1509: after promoting the QoS success, PCRF sends to UE and promotes QoS affirmation request message alternatively, requires the QoS after the user is confirmed whether satisfied the renewal.Perhaps in step 1508, carry this affirmation indication.

After step 1510:UE receives the affirmation message of this PCRF, if satisfied and be ready to pay the expense that preferential flow is processed to upgrading business data flow after (for example promoting), then this message is confirmed, UE will send to acknowledge message to PCRF, operator will (for example continue to provide lifting QoS afterwards to this business, proceed preferential flow and process, high priority or high bandwidth resource are provided).If UE to the service quality of the business data flow after promoting or the user experiences dissatisfied and or the outer priority treatment expense of amount paid of being unwilling, then the user does not confirm (not returning response message) to this affirmation request or returns negative acknowledgement message to PCRF (if namely the user disagrees with that carrying out new service quality provides this business but the affirmation of not answering in the negative answer, then terminal equipment makes up alternatively negative acknowledgement message according to operator's demand and sends to PCRF).

In the such scheme, PCRF can arrange QoS and promote timer Timer1 (the Timer1 term of validity should be able to guarantee that IP-CAN session modification that normal PCRF initiates upgrades QoS and is disposed and provides applied business by new QoS for UE) in step 1507, Timer1 is overtime, sends to UE and confirms request message.Specifically arrange according to realizing, present embodiment is not done restriction.

PCRF opens the user and confirms timer Timer2 after can also sending in step 1509 and promoting QoS affirmation request message.

Step 1510a: then will send the QoS request of upgrading (for example, reducing the QoS request) to PCRF if the user confirms refusal;

Step 1510b: if PCRF at the appointed time (for example timer2 duration) do not receive user's affirmation receipt message, or after PCRF receives that UE reduces the QoS request message, in conjunction with CAMEL-Subscription-Information and local policy (for example user confirm to receive the Preview timer2 of update QoS is overtime then need to recover original QoS), initiate IP-CAN/GWcontrol/TDF session modification flow process, upgrade relevant PCC/QoS/ADC rule, recover the former QoS of this business;

Step 1510c: after the QoS Recovery processing is finished or promote the QoS acknowledging time overtime after, network will return to the QoS of UE request before promoting to the processing of this business data flow.

Wherein, the QoS fallback mechanism is not in the limited range of this programme, can adopt for example rollback time of the mechanism of the timer between network element processing session modification, can locally store update QoS before, carry QoS information before this when perhaps UE sends downgrade QoS request message, perhaps portably use acquiescence QoS indication etc. in the request message.

In the said method, step 1509 is optional steps.Can also adopt terminal self to trigger the mode that updating service quality is confirmed request.

In the above flow process, PCRF is integrated or strengthen Trigger Function, and PCRF carries out modification, renewal and the affirmation service quality of IP-CAN session according to the triggering of internal trigger function.

Above step 1501-1510 is the handling process of non-roaming scene, in the professional use procedure, as shown in figure 16, if UE roams into visited place (roaming ownership place route scene), ownership place PCRF needs notification triggers function UE that roaming has occured, if then also need the UE to reaffirm whether to need to keep high QoS/ high priority flows to process (to process if the user confirms the high QoS of this business for having promoted QoS before this, then may need the outer high priority flows disposal cost of amount paid), if the user confirms that then the visited place is still for this UE provides high QoS, if the user does not confirm or Negative Acknowledgement then will adopt acquiescence QoS that this business is provided in the visited place; As shown in figure 17, concrete steps are as follows:

Step 1511:HPCRF knows that roaming has occured UE, sends QoS and confirms Indication message to UE, and notice UE roaming, and send the affirmation that preferential flow processes and indicate to UE, request UE is confirmed whether to continue to use the processing of QoS priority business stream in the visited place;

Step 1512: Trigger Function sends the affirmation request message that preferential flow is processed high QoS to UE, require the user to be confirmed whether to keep high QoS stream and process, if keep then return sure affirmation message (confirm to keep high QoS may need for this reason preferential flow to process extra rate are provided); If disagree with the preferential flow disposal cost that amount paid is outer, then return negative affirmation or do not confirm (if the user does not confirm, then terminal equipment may make up Negative Acknowledgement and return to network, distinguishing the user during the technology of being convenient to realizes does not send and confirms and abnormal case that acknowledge message is lost, but concrete the processing according to carrier network realizes processing), execution in step 1513a-c.This handling process, PCRF can arrange the user and confirm timer Timer3 when send confirming request, if if timeout does not receive that yet positive acknowledgement then initiates to reduce the QoS handling process);

Step 1513a: if PCRF at the appointed time (for example timer3 duration) do not receive user's affirmation receipt message, or received user's affirmation refuse information, then UE will send the QoS request of upgrading (for example, reducing QoS) alternatively to PCRF;

Step 515b:HPCRF receive the reduction QoS request message of UE/or negative acknowledgement response message after, in conjunction with CAMEL-Subscription-Information and local policy (for example the user confirms that the timer expiry that keeps high QoS then needs to reduce QoS), initiate IP-CAN/GWcontrol/TDF session modification flow process, upgrade relevant PCC/QoS/ADC rule, recover the acquiescence QoS of this business;

Step 515c: finish session modification, recover the acquiescence QoS to this business data flow, issue this business data flow by default bearing QoS.If UE has sent 1513a request QoS downgrade to PCRF before this, then PCRF send Ack message to UE as response.

More than the deployment of roaming strengthens Trigger Function based on ownership place PCRF, and is mutual with UE.Real network is disposed also can be UE and visited place PCRF direct interaction (VPCRF strengthens Trigger Function), and then VPCRF forward pass information depends on specifically that to HPCRF operator disposes with roaming agreement.

Based on Fig. 3-2 method, strengthen the embodiment of Trigger Function based on PCRF on the network configuration basis of GBA and OpenID, with reference to embodiment two and three and the contrast of embodiment one, and Figure 15,16,17; No longer be repeated in this description herein.
