Description
Technical field
The present invention relates to the communications field, insert the policy and rule synchronization method of 3GPP network in particular to a kind of subscriber equipment.
Background technology
As shown in Figure 1, EPS (the Evolved Packet System that 3GPP proposes, the grouping system of evolution) by E-UTRAN (Evolved Universal Terrestrial RadioAccess Network, the universal terrestrial access network of evolution), MME (MobilityManagement Entity, mobile management unit), S-GW (Serving Gateway, gateway), P-GW (PDN GW, Packet Data Network Gateway, grouped data network gateway), HSS (Home Subscriber Server, home subscriber server), 3GPP AAA (Authentication Authorization and Accounting, authentication and authorization charging) server, PCRF (Policy and Charging Rules Function, "Policy and Charging Rules Function), reaching other support nodes forms.
Wherein, MME is responsible for the processing of mobile management, Non-Access Stratum signaling, user's chain of command related works such as the contextual management of mobile management;
S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory;
P-GW is the EPS of 3GPP and the borde gateway of PDN (Packet Data Network, packet data network), be responsible for to insert PDN and transmit function such as data between EPS and PDN;
PCRF obtains business information on the one hand by Rx interface and operator's IP operation network interface; It links to each other with gateway device in the network by the Gx/Gxa/Gxc interface on the other hand, is responsible for initiating the foundation of IP carrying, the QoS (Quality ofService, service quality) of assurance business datum, and the control of chargeing.
EPS realizes and the intercommunication of non-3GPP network that by the S2a/b/c interface P-GW is as 3GPP and the internetwork anchor point of non-3GPP.Wherein, non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP access.The non-3GPP IP of trusted inserts can be directly by S2a and P-GW interface; Trustless non-3GPP IP inserts to be needed to link to each other with P-GW through E-PDG (Evolved Packet Data Gateway, the packet data gateway of evolution), and the interface between E-PDG and P-GW is S2b.S2c is the interface between UE and the P-GW, adopts DSMIPv6 (Dual Stack Mobile IPv6, two stack mobile IP v 6s) agreement that control and mobile management are provided.
With reference to figure 1, in traditional 3GPP network, PCEF (Policy and chargingenforcement function, strategy and charge execution function) exist only among the P-GW, PCRF needs only the control that can finish all functions with the P-GW interface, passes through Gx interface exchange message between PCRF and P-GW.Interface when between P-GW and S-GW is based on PMIPv6 (Proxy Mobile Internet Protocol version 6, the proxy mobile IP protocol sixth version) time, policy enforcement function part in the PCEF function also is present among the S-GW, be called bearing binding and event reporting function (Bearer Binding and Event ReportingFunction, abbreviate BBERF as), pass through Gxc interface exchange message between S-GW and the PCRF.When subscriber equipment inserts by the non-3GPP connecting system of trusted, the also resident BBERF in the trusted non-3 GPP access network Central Shanxi Plain.Pass through Gxa interface exchange message between trusted non-3 GPP access network pass and the PCRF.When UE roamed, the S9 interface was as the interface of ownership PCRF and visit PCRF.For providing professional AF (ApplicationFunction, application function), UE sends the business information that is used to formulate PCC (Policy and Charging Control, the strategy and the control of chargeing) strategy to PCRF simultaneously by the Rx+ interface.
Fig. 2 is that UE passes through the attachment flow figure that the trusted non-3 GPP access network inserts 3GPP and adopts the PMIPv6 agreement.As shown in Figure 2, this method may further comprise the steps:
Step S201, UE inserts the trusted non-3 GPP access network;
After step S202, UE are linked into the trusted non-3 GPP access network, to HSS/AAA request carrying out EPS access authentication.After HSS/AAA receives the request of EPS access authentication, the UE of the request of sending is authenticated.After HSS/AAA finishes authentication to UE, close to the trusted non-3 GPP access network and to send the APN (Access Point Name abbreviates APN as) that the signatory P-GW of UE selects information and UE;
Step S203, behind the authentication success, the attachment flow of layer 3 is triggered;
Step S204, trusted non-3 GPP access network close to PCRF transmission gateway control session and set up request message, set up network access Identifier (Network Access Identifier abbreviates NAI as) and the APN that carries UE in the request message in gateway control session;
Step S205, PCRF receives after gateway control session sets up request message, according to the CAMEL-Subscription-Information of the NAI of UE and APN inquiry UE, formulate qos policy according to the CAMEL-Subscription-Information that inquires, and set up acknowledge message by gateway control session and send to the non-3GPP gateway of trusted;
After step S206, trusted non-3 GPP access network close and receive P-GW selection information,, and, carry NAI and the APN of UE in the agent binding update messages to selected P-GW transmission agent binding update messages according to the selected P-GW of P-GW selection information;
Step S207, after P-GW receives agent binding update messages, send IP-CAN (IP Connectivity Access Network, IP connects Access Network) session to PCRF and set up indication, setting up the NAI, the P-GW that carry UE in the indication in the IP-CAN session is UE IP address allocated and APN;
Step S208, PCRF receive after the IP-CAN session sets up indication, according to the NAI of UE and the CAMEL-Subscription-Information of APN inquiry UE, formulate PCC rule and QoS rule according to the network strategy that disposes among user's CAMEL-Subscription-Information and the PCRF.After PCRF finishes PCC and QoS Rulemaking, send the IP-CAN session to P-GW and set up acknowledge message, set up in this IP-CAN session and carry the PCC rule in the acknowledge message;
Step S209, P-GW receive after the IP-CAN session sets up acknowledge message, install also to carry out the IP-CAN session and set up the PCC rule of carrying in the acknowledge message, and the IP address with himself sends to HSS simultaneously;
Step S210, P-GW close to the trusted non-3 GPP access network and return proxy binding acknowledgment messages;
Step S211, if the QoS rule that issues in the QoS that formulates in the step 208 rule and the step 205 is different, then PCRF gives trusted non-3 GPP access network pass by gateway control and the qos policy rule QoS rule downloading that will upgrade that gives information;
Step S212, trusted non-3 GPP access network close to install the QoS rule, and return gateway control and the qos policy rule provides affirmation;
Step S213, layer 3 adheres to be finished;
Step S214 sets up the PMIPv6 tunnel between trusted non-3 GPP access network pass and the P-GW, and UE can carry out the data transmission or accept, and flow process finishes.
By this flow process, UE has set up an IP to PDN and has connected, and is called the IP-CAN session; And P-GW and PCRF and trusted non-3 GPP access network close and PCRF has set up a Diameter session respectively.These two Diameter sessions are relevant with the IP-CAN session of UE foundation.
Fig. 3 is that UE inserts the attachment flow figure that adopts GTP (General Data Transfer Platform, conventional data transmission platform) between 3GPP and S-GW and the P-GW by E-UTRAN.As shown in Figure 3, this method may further comprise the steps:
Step S301, UE send Attach Request message to MME, and MME initiates the identifying procedure to UE, exchanges authentication-related information between MME and the HSS as required.Behind the authentication success, MME initiates more new technological process of position, and HSS sends to MME with the subscription data of UE.In verification process, HSS sends to MME with the selection information of P-GW, and MME selects S-GW and P-GW;
Step S302, MME sends the default bearing request of setting up to S-GW;
Step S303, S-GW sends the default bearing request of setting up to P-GW;
Step S304, P-GW sends the IP-CAN session to PCRF and sets up indication;
Step S305, PCRF be according to user's CAMEL-Subscription-Information, and network strategy is formulated the PCC strategy, and set up acknowledge message by the IP-CAN session and bring P-GW;
Step S306, P-GW return to S-GW and set up default bearing and reply;
Step S307, S-GW return to MME and set up default bearing and reply;
Step S308, MME initiates to set up radio bearer, and notice UE adheres to successfully;
Step S309, MME initiates bearer update, and radio bearer information is sent to S-GW;
Step S310 sets up RAB between UE and the S-GW, sets up GTP tunnel between S-GW and the P-GW.
By above-mentioned flow process, UE and PDN have set up an IP-CAN session, and have set up a Diameter session between P-GW and the PCRF, and this Diameter is relevant with the IP-CAN session of UE foundation.
The attachment flow that inserts EPS by above-mentioned two kinds of UE is as can be known: when UE closes by the trusted non-3 GPP access network and adopts PMIPv6 to insert, PCRF needs and trusted non-3 GPP access network pass is carried out mutual, close to the trusted non-3 GPP access network QoS rule downloading, and, PCRF also will carry out alternately with P-GW, gives P-GW with the PCC rule downloading; And UE is when inserting EPS by adopting the GTP agreement between E-UTRAN and S-GW and the P-GW, and PCRF only needs carry out alternately with P-GW, issues the PCC rule to it.
Because the PCC rule comprises control and the charging of QoS, and has only the control of QoS in the QoS rule.The charge information of PCC rule is relevant with the QoS that provides, and the QoS control in control of the QoS in the QoS rule and PCC is inequality, and it is inaccurate to cause chargeing, thereby the mismatch of policy and charging control occurs.
When UE closes by the trusted non-3 GPP access network and adopts PMIPv6 to insert, the trusted non-3 GPP access network closes does not support dynamic PCC, and during the dynamic PCC of 3GPP network support, PCRF can be with the PCC rule downloading to P-GW, and the QoS rule downloading can't be closed to the trusted non-3 GPP access network, cause P-GW and trusted non-3 GPP access network to close and carry out unmatched strategy.
Equally, when UE roams, home network is supported PCC if access zone network is not supported dynamic PCC, and PCRF can be with the PCC rule downloading to the P-GW that is in home network, and the QoS rule downloading can't be given S-GW or the trusted non-3 GPP access network pass that is in access zone network.
In realizing process of the present invention, the inventor finds that the QoS control between a plurality of in the prior art network elements is asynchronous with the control of chargeing.
