Description

A kind of method, system and PCRF for realizing reflection QoS mechanism

Technical field

The present invention relates to third generation partner program (3GPP, 3rd Generation Partnership Project) Service quality is reflected with Broadband Forum (BBF, Broadband Forum) interconnection and interflow technical field, more particularly to a kind of realize The method, system and PCRF of (QoS, Quality of Service) mechanism.

Background technology

Grouping system (EPS, the Evolved Packet System) structure composed of existing 3GPP evolution as shown in Figure 1, In the EPS network architectures of non-roaming scene shown in Fig. 1, include the Universal Mobile Communication System land radio access web of evolution (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), mobile management unit (MME, Mobility Management Entity), gateway (S-GW, Serving Gateway), packet data network Gateway (P-GW, Packet Data Network Gateway, also referred to as PDN GW), home subscriber server (HSS, Home Subscriber Server), "Policy and Charging Rules Function entity (PCRF, Policy and Charging Rules ) and other support nodes Function.

Wherein, PCRF is the core of strategy and charging control (PCC), is responsible for strategic decision-making and the formulation of charging regulation. PCRF provides the network control rule based on business data flow, and the control of these networks includes the detection of business data flow, gate (Gating Control), QoS control and the charging regulation based on data flow etc..The strategy and charging rule that PCRF is formulated Then it is sent to strategy and charging execution function entity (PCEF, Policy and Charging Enforcement Function) Perform, meanwhile, PCRF also needs to ensure that these rules are consistent with the signing information of user.PCRF generates strategy and charging regulation Foundation includes：Obtained and the relevant information of business from Application Function (AF, Application Function)；Signed from user About database (SPR, Subscription Profile Repository) obtains user policy, billing control and subscription information；From PCEF obtains the information with carrying network of relation.

EPS supports the intercommunication with non-3 GPP system, and the intercommunication of EPS and non-3 GPP system is realized by S2a/b/c interfaces, P- GW is as the anchor point between 3GPP and non-3 GPP system.As shown in Figure 1, wherein, non-3 GPP system is divided into trusted non-3 gpp IP Access and trustless non-3 gpp IP accesses.Trusted non-3 gpp IP accesses can be directly connected by S2a interfaces with P-GW；No Trusted non-3 gpp IP accesses packet data gateway (ePDG, Evolved Packet Data Gateway) that need to be Jing Guo evolution It is connected with P-GW, the interface between ePDG and P-GW is S2b interfaces, and user equipment (UE, User Equipment) and ePDG Between protection is encrypted to signaling and data using Internet protocol security (IPSec).S2c interfaces provide UE and P- The relevant control of user plane and mobility support between GW, its mobility management protocol supported are the movement for supporting double stacks IPv6 (DSMIPv6, Mobile IPv6 support for dual stack Hosts and Routers).

At present, many operator's concern fixed network mobile fusions (FMC, Fixed Mobile Convergence), and be directed to 3GPP and BBF interconnects and is studied.For user by the scene of BBF access mobile core nets, it is necessary to the whole of data QoS on a transmission path (data can pass through fixed network and mobile network transmits) is ensured.In the prior art, by PCRF with Broadband policy control framework (BPCF, Broadband Policy Control Framework) in BBF accesses interacts, Realize that QoS is ensured.BPCF is the policy control architecture in BBF accesses, and to the resource request message of PCRF, BPCF connects according to BBF The network strategy that enters, signing information etc. carry out resource and admission control or resource request message are transmitted to its of BBF access nets His network element, such as wideband network gateway (BNG, Broadband Network Gateway), then perform resource and admission by other network elements Control (entrusts other network elements to perform resource and admission control).Such as：When UE accesses 3GPP cores by WLAN (WLAN) During heart net, in order to which the total bandwidth need for all UE access services for ensureing to access by a WLAN line attachment is no more than the line The bandwidth (the greatest physical bandwidth supported such as signing bandwidth or the circuit) on road, PCRF is needed when carrying out QoS mandates and BPCF Interaction, so that BBF accesses the admission control of net execution resource.

The research that 3GPP and BBF interconnect at present mainly includes two aspects：3GPP UE are accessed by the WLAN of BBF The scene and 3GPP UE of the packet-based core networks (EPC, Evolved Packet Core) of evolution access 3GPP cores by H (e) NB The scene of heart net, wherein, BBF access nets are connected to 3GPP core nets by H (e) NB as Backhaul (routed path).

Fig. 2 is in the prior art, UE accesses the configuration diagram of 3GPP core nets by WLAN, as shown in Fig. 2, BBF connects Network and be used as fly-by-night non-3 GPP access.At present, based on the framework shown in Fig. 2, accessed in the prior art in UE by BBF During net access EPC, S9a sessions can be established between BPCF and PCRF, to carry out tactful intercommunication.When UE carries out business visit Ask need network for its distribute resource when, the QoS information of the PCC rules of formulation is sent to BPCF by PCRF first, so that BBF connects Network and perform admission control.Then, BBF is accessed the PCC rules netted and received and is sent to PCEF by PCRF.For business data flow Downlink data, PCEF carry out the head (being known as internal packet header) of the IP bags of corresponding data flow downlink data according to PCC rules The mark of differentiated services code points (DSCP, Differentiated Services Code Point), when the business data flow Downlink data IP bags reach ePDG when, ePDG will to IP bags carry out IPSec encapsulation, and encapsulation when according to IP bags (inside Packet header) DSCP the head (being known as exterior packet header) of the IP bags of IPSec is marked.In this way, BBF access nets can basis The DSCP of the IP packet headers of IPSec carries out data packet and forwarded.For the upstream data of business data flow, since UE can not be obtained The qos policy of formulation, provides a kind of mechanism for being known as reflection (Reflective) QoS and realizes business data flow in the prior art The QoS controls of upstream data, its main thought are：UE is according to the DSCP values of the downlink data of business data flow to the business datum Flow the corresponding upstream data of downlink data and carry out DSCP marks, the upstream data of business data flow and the IP bags n members of downlink data Group (n-tuple) is symmetrical.

In the prior art, the scene of net access EPC is accessed by BBF for UE, is performed when UE access BBF accesses net During 3GPP-based access authentications, 3GPP AAA (award by Authentication Authorization Accounting, certification Power charging) whether server will perform the decision of reflective QoS mechanism and notify to UE.But this method is lacked there are following Fall into：

First, not every UE is carried out 3GPP-based access authentications when accessing BBF access nets；

Secondly, network can not effectively control the UE not performed by network decision in this method, even if network refers to Show that the UE does not perform reflective QoS mechanism, but UE still carries out reflective QoS mechanism, and network can not prevent The UE seizes the resource of other UE.

At present, the scene of net shunting access service is accessed by BBF for UE, Reflective QoS mechanism can be used Realize the QoS controls of business data flow upstream data, but whether the prior art also performs without a kind of method notice UE of proposition Reflective QoS mechanism, and allow the network to be controlled accordingly.

It is further detailed to the above-mentioned method and system for realizing Reflective QoS mechanism with reference to specific embodiment Illustrate.

The embodiment of the present invention one as shown in figure 4, Fig. 4 for UE by trustless BBF access net access 3GPP core nets, Under non-roaming scene, whether network performs UE the flow that Reflective QoS mechanism carries out strategic decision-making.In Fig. 4, ePDG GPRS Tunnel Protocol (GTP, GPRS Tunnel Protocol) agreement is used between P-GW.The flow mainly includes following step Suddenly：

Step 401, alternatively, after UE access BBF access systems, the access authentication based on 3GPP is performed, UE provides international Mobile identification number (IMSI, International Mobile Subscriber Identification Number), is used In access authentication.

In access authentication procedure, 3GPP aaa servers determine whether the UE performs reflective QoS mechanism, and By the decision notification UE.Alternatively, UE whether it is performed first reflective QoS mechanism ability instruction notice to 3GPP aaa servers, 3GPP aaa servers indicate to determine whether the UE performs reflective QoS machines further according to the ability System.

Step 402, UE obtains local ip address from BBF access nets, and the address is by home gateway (RG, Residential Gateway) or BNG is distributed.

Step 403, the triggering of step 401 or step 402 is received, BPCF is notified UE access BBF access nets.If step In 401, whether 3GPP AAA perform the UE reflective QoS mechanism and carry out decision-making, then BPCF obtains the result of decision.

Step 404, BPCF sends gateway control session to PCRF and establishes message, wherein carrying the user identifier of UE, local IP address.If in step 403, BPCF obtains the result of decision whether UE performs reflective QoS mechanism, then BPCF The result of decision is sent to PCRF.

Step 405, PCRF returns to gateway control session to BPCF and establishes confirmation message.

Optionally, PCRF needs and SPR interactions obtain contracted user's strategic decision-making of user.

Step 406, after UE selects ePDG, Internet Key Exchange (IKEv2) tunnel establishment procedure is initiated, and adopt It is authenticated with Extensible Authentication Protocol (EAP, Extensible Authentication Protocol).If UE and ePDG are deposited NA (P) T (there are NA (P) T such as on RG), then IKEv2 signalings will perform network address translation (NAT, Network Address Translation) pass through.During ipsec tunnel is established, 3GPP aaa servers determine whether the UE performs Reflective QoS mechanism, and the decision notification UE, ePDG can be obtained into the decision-making.

Optionally, UE whether it is performed first reflective QoS mechanism ability instruction notice give 3GPP AAA clothes Business device, 3GPP aaa servers indicate to determine whether the UE performs reflective QoS mechanism further according to the ability.

Optionally, local ip address or access network type can be also sent to 3GPP aaa servers, 3GPP AAA by ePDG Server judges that UE accesses net access by BBF according to local ip address or access network type, so as to further determine that the UE is No execution reflective QoS mechanism.

Passed through since IKEv2 signalings may have passed through NA (P) T, the source address and source port number that ePDG is received can Source address and source port number when can be sent from UE is different.If not passed through by NA (P) T, source address is that UE is being accessed The local ip address obtained during BBF access nets.

Scene for NA (P) T is not present between UE and ePDG, the source for the IKEv2 signalings that the UE that ePDG is received is sent Address is the local ip address of BBF access net distribution, and the address can be encapsulated with the unique mark UE by the ipsec tunnel Business data flow.

For having (1 between UE and ePDG：1) scene of NAT, the source for the IKEv2 signalings that the UE that ePDG is received is sent Address is the public network IP address after NAT, but due to being (1：1) NAT, the address still can be with the unique mark UE by this The business data flow of ipsec tunnel encapsulation.

For there is (N between UE and ePDG：1) scene of NAT (i.e. NAPT), business data flow are needed in passing through NAT User Datagram Protocol (UDP, User Datagram Protocol) encapsulation is carried out, NAPT can be that the ipsec tunnel distributes source UDP port number (for the up direction of UE).Therefore, for business that the unique mark UE is encapsulated by the ipsec tunnel Data flow, at least needs the source address (public network i.e. after NAT is netted in BBF accesses for the IKEv2 signalings that the UE that ePDG receives sends IP address, if NAT is located at RG, which is exactly the address of RG) and the source ports of IKEv2 signalings that send of the UE that receive of ePDG Number (i.e. IPSec sources UDP port number).

For convenience of description, UE is also referred to as local ip address by the IP address of NAT.

Step 407, after ePDG selects P-GW, sent to P-GW and create conversation request message, creating conversation request message In carry UE user identifier, packet data network (PDN, Packet Data Network) mark and local ip address With source UDP port number (if detecting NA (P) T, source UDP port number is carried in message).

The network obtained in step 406 can also be determined whether UE performs the decision-making of reflective QoS mechanism by ePDG It is sent to P-GW.

Step 408, P-GW distributes IP address for UE, and the PCEF positioned at P-GW sends the instruction of IP-CAN session establishments to PCRF Message, carries the user identifier of UE, PDN is identified, the IP address for UE distribution, UE in IP-CAN session establishment instruction messages Local ip address and source UDP port number (if detecting NA (P) T, source UDP port number is carried in message).Meanwhile P-GW The decision-making whether network decision UE can be performed to reflective QoS mechanism is sent to PCRF.

Step 409, when PCRF formulates PCC rules, except considering subscription data, network strategy and access net attribute etc., also To determine whether UE performs the decision-making of reflective QoS mechanism according to network.If network determines that UE performs Reflective QoS mechanism, then to formulate the PCC rules of Reflective QoS mechanism, i.e., the PCC of same business data flow up-downlink direction The QoS of rule is identical, i.e. QoS classification logotypes (QCI, QoS Class Identifier) and/or distribution keeps priority (ARP, Allocation and Retention Priority) is identical；If network determines that UE does not perform Reflective QoS Mechanism, then can formulate be not Reflective QoS mechanism PCC rule, i.e., same business data flow up-downlink direction The QoS of PCC rules differ, i.e. QCI and/or ARP are differed.

The PCC rules of formulation are sent to PCEF by PCRF by IP-CAN session establishment confirmation messages.

Further, PCRF is according to PCC Rulemakings QoS rules.

Step 410, P-GW sends renewal P-GW IP address message to AAA Server, and the address of P-GW is sent to AAA Server, AAA Server are further interacted with HSS and the address of P-GW are saved in HSS.

Step 411, P-GW is returned to ePDG and is created session confirmation message, and promising UE is carried in session confirmation message is created The IP address of distribution.

Step 412, ipsec tunnel is established between UE and ePDG.

Step 413, ePDG sends the last item IKEv2 signalings to UE, wherein carrying the IP address of UE.

Step 414, if step 404, step 405 perform, PCRF performs gateway control and QoS rules provide flow, to BPCF provides UE local ip address, source UDP port number (if detecting NA (P) T, providing source UDP port number), and formulates QoS rule.

If being not carried out step 404, step 405, PCRF performs the gateway control session Establishing process that PCRF is initiated, to BPCF provides UE local ip address, source UDP port number (if detecting NA (P) T, providing source UDP port number), and formulates QoS rule.

Step 415, strategy is supplied to BNG/ Broadband Remote Access Server (BRAS, Broadband Remote by BPCF Access Server)。

By above-mentioned flow, UE obtains network and determines whether UE performs the decision-making of Reflective QoS mechanism, at the same time PCRF also obtain the decision-making.Hereafter, when UE, which carries out Operational Visit, needs network to distribute resource for it, PCRF is formulating PCC The decision information will be considered when regular, specifically：If network determines that UE performs Reflective QoS mechanism, then to formulate The PCC rules of Reflective QoS mechanism, i.e., the QoS of the PCC rules of same business data flow up-downlink direction be it is identical, That is QCI and/or ARP are identical；If network determines that UE does not perform Reflective QoS mechanism, then can formulate is not The PCC rules of Reflective QoS mechanism, i.e., the QoS of the PCC rules of same business data flow up-downlink direction are differed, That is QCI and/or ARP are differed.Then, the QoS information of the PCC rules of formulation is sent to BPCF by PCRF, so that BBF accesses net Perform admission control and strategy execution.BBF access nets can be mapped to specific DSCP, therefore BBF according to QCI and/or ARP Access the corresponding bandwidth of each DSCP of each UE of strategy decision that net can be provided according to PCRF.

Certainly, PCRF can also by BBF access net provide one it is explicit whether execution Reflective QoS machines The instruction of system come notify BBF access net the UE whether perform Reflective QoS mechanism.Such as performing Reflective QoS During mechanism, PCRF is provided to BPCF performs the instruction of Reflective QoS mechanism, and BBF, which accesses net, at this time can know that the UE's is same The QCI and/or ARP of a business data flow uplink and downlink are identical (even if the QCI in PCC rules or QoS rules that PCRF is issued And/or ARP is different).

Since in the prior art, BBF access nets can realize the bandwidth limitation of per UE per DSCP, therefore combine this Whether the embodiment of invention, PCRF allow the different strategy of the decision-making of UE execution Reflective QoS mechanism for network BBF access nets are handed down to, whether BBF access nets, which can perform UE Reflective QoS mechanism, control effectively, especially It is that the UE that those are not performed with Reflective QoS mechanism by network decision can also control effectively.

The embodiment of the present invention two as shown in figure 5, Fig. 5 for UE by trustless BBF access net access 3GPP core nets, Under non-roaming scene, whether network performs UE the flow that Reflective QoS mechanism carries out strategic decision-making.In Fig. 5, ePDG Proxy mobile IPv 6 (PMIPv6) agreement is used between P-GW.The flow mainly includes the following steps that：

Step 501~506 are identical with step 401~406, and details are not described herein again.

Step 507, ePDG sends gateway control session to PCRF and establishes message, wherein carrying the user identifier of UE, PDN Mark and local ip address and source UDP port number (if detecting NA (P) T, source UDP port number is carried in message).

The network obtained in step 506 can also be determined whether UE performs the decision-making of reflective QoS mechanism by ePDG It is sent to PCRF.

Step 508, PCRF returns to gateway control session to ePDG and establishes confirmation message.

Step 509, after ePDG selects P-GW, agent binding update messages are sent to P-GW, in agent binding update messages In carry UE user identifier and PDN mark.

Step 510, P-GW distributes IP address for UE, and the PCEF positioned at P-GW sends the instruction of IP-CAN session establishments to PCRF Message, carries the user identifier, PDN marks, the IP address for UE distribution of UE in IP-CAN session establishment instruction messages.
