Description
Technical field
The present invention relates to communication technical field, relate in particular to method, the equipment and system of a kind of definite user ID and notice user ID.
Background technology
Local network (home network, enterprise network etc.) refers to the IP network that non-operator disposes, and user terminal (UE) can pass through the access way access local networks such as Home eNodeB, WLAN.Local network comprises: UE is accessed to the LIPA(Local IP Access of local network by local gateway, local IP access) technology, and the SIPTO(Selected IP Traffic Offload that accesses the business networks such as Internet by local gateway, the selectivity IP traffic) technology.In LIPA or SIPTO scene, set up the end user path between Home eNodeB and local gateway, make user data without through the core net transmission, can obtain preferably data route path.
At the LTE(Long Term Evolution) in system, being connected as shown in Figure 1 between Home eNodeB subsystem and core net, wherein, MME(Mobility Management Entity, Mobility Management Entity) be the control node of core net, be responsible for carrying out LIPA access control, carrying foundation etc.; LGW(Local Gateway, local gateway) by S5 interface and SGW(Serving Gateway, gateway) be connected, when the LIPA connection is set up, between LGW and SGW, also to set up carrying; In addition, LGW and H (e) NB(Home(evolved) NodeB, (evolved) Home eNodeB) between, by the Sxx interface, be connected, after LIPA connects foundation, user's face will directly enter local network by H (e) NB and LGW, without the core net of operator; PGW(PDN GW, Packet Data Network Gateway, grouped data network gateway) be gateway in core net; PCRF(Policy Control and Charging Rules Function, strategy and charging regulation entity) provide dynamic PCC(Policy and Charging Control to PGW, strategy and charging are controlled) rule, in 3GPP R11, under same LGW, can connect a plurality of HeNB.
In this system architecture, after MME access control success, can be the LIPAPDN connection that UE is established to LGW, user's face that this LIPA PDN connects is without core net, it is with the difference that common PDN is connected, the control node of core net is selected the PGW in LGW rather than core net, and also needs to set up directapath between LGW and H (e) NB.
When core net is enabled dynamic PCC, PGW sets up IP-CAN(IP-Connectivity Access Network to PCRF, IP connects access network) session ask the PCC rule, wherein PGW provides user ID and APN(Access Point Name, APN).For PDN connects the process of establishing schematic diagram, wherein, MME is that terminal is set up the PDN connection, after sending the establishment conversation request message to PGW, enters the request of PCC rule and issues process as shown in Figure 2:
Step 201:PGW sends and creates the IP-CAN conversation request message to PCRF, this message comprises user ID and packet data network identification, in the LTE core net, user ID is by IMSI(International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity) the UE NAI(User Equipment Network Access Identifier that structure forms, user equipment network access sign), packet data network identification is APN;
Step 202:PCRF carries out strategic decision-making, PCRF may need the Repository to SPR(Subscription Profile, user information store) the request CAMEL-Subscription-Information carrys out aid decision, and PCRF adopts user ID and optional APN to ask CAMEL-Subscription-Information to SPR.
Step 203:PCRF returns to IP-CAN session establishment response message, comprising the PCC rule.
Connect process of establishing according to the PDN defined in agreement TS23.401 afterwards and complete subsequent process.
Wherein, use PMIP(Proxy Mobile IP between SGW and PGW, proxy-mobile IP) during agreement, also need to set up gateway control session (GW Control Session) between SGW and PCRF in PDN connection process of establishing, to SGW, to transmit bearing binding relevant parameter and QoS(Quality of Service, service quality) rule (now PGW does not carry out bearing binding and carries level QoS and controls function).As shown in Figure 3, the gateway control session process between SGW and PCRF is as follows:
Step 301:SGW, after receiving the establishment conversation request message of MME, sends gateway control session to PCRF and sets up request message initiation process of establishing, and this request message comprises user ID (IMSI), APN etc.; PCRF returns to gateway control session and sets up response, and comprising the QoS rule etc., in this process, PCRF may ask CAMEL-Subscription-Information to SPR;
Step 302:SGW sends the agent binding request message to PGW, sets up the PMIP tunnel between SGW and PGW, and PGW initiates IP-CAN session establishment process to PCRF, obtains the PCC rule that PCRF issues;
Step 303:PGW returns to the agent binding response message to SGW.
Known according to agreement 3GPP TS23.203, have same subscriber sign corresponding with the IP-CAN session with the gateway control session of APN same PDN be connected.
Known according to current standard, PGW need to provide user ID during to the PCRF request strategy, and PCRF also needs the user to identify from SPR to obtain CAMEL-Subscription-Information, carry out session association etc., and, in the LTE core net, user ID is the UE NAI that the IMSI structure forms.
3GPP R10 and R11 stage are not supported to be connected dynamic PCC rule is provided to LIPA or SIPTO, yet for providing QoS better, the user to the access local network experiences in follow-up evolution, need to support locally-attached policy control, PCRF need to issue the PCC rule to LGW.Because LGW does not belong to the entity in core net, the IMSI of UE is passed to LGW and will have security threat, therefore core net node can not pass to LGW by IMSI, but, if can't get user ID from LGW according to existing protocol PCRF, just can't ask CAMEL-Subscription-Information to SPR, also just can not carry out the PCC rule and issue.
