The control node of net, is 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, work as LIPA
During connection establishment, carrying to be set up between LGW and SGW；Additionally, LGW Yu H (e) NB(Home
(evolved) NodeB, (evolved) Home eNodeB) between be connected by Sxx interface, LIPA is even
After connecing foundation, user face directly will enter local network by H (e) NB and LGW, without operator
Core net；PGW(PDN GW, Packet Data Network Gateway, grouped data network gateway)
It it is gateway in core net；PCRF(Policy Control and Charging Rules Function, strategy and meter
Take rule entity) provide dynamic PCC(Policy and Charging Control, strategy and meter to PGW
Take control) rule, in 3GPP R11, multiple HeNB under same LGW, can be connected.
In this system architecture, after MME Access Control success, can be the UE LIPA that sets up LGW
PDN connects, and the user face that this LIPA PDN connects is without core net, and it is connected with common PDN
Difference is, the node that controls of core net selects the PGW in LGW rather than core net, and LGW
And also need between H (e) NB to set up directapath.
When core net enables dynamic PCC, PGW sets up IP-CAN(IP-Connectivity to PCRF
Access Network, IP connect access network) session and ask PCC rule, wherein PGW provide use
Family mark and APN(Access Point Name, APN).Connect for PDN as shown in Figure 2
Setting up process schematic, wherein, MME is that terminal sets up PDN connection, sends to PGW and creates session
After request message, enter the request of PCC rule and issue process:
Step 201:PGW sends to PCRF and creates IP-CAN conversation request message, and this message includes
ID and packet data network identification, in LTE core network, ID is by IMSI
The UE of (International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity) structure
NAI(User Equipment Network Access Identifier, user equipment network accesses mark), point
Group data network is designated APN；
Step 202:PCRF carries out strategic decision-making, and PCRF may need to SPR(Subscription Profile
Repository, user information store) ask CAMEL-Subscription-Information to carry out aid decision, PCRF uses ID
And optionally APN asks CAMEL-Subscription-Information to SPR.
Step 203:PCRF returns IP-CAN session establishment response message, including PCC rule.
Subsequent process is completed afterwards according to the PDN connection establishment process defined in agreement TS23.401.
Wherein, between SGW and PGW, PMIP(Proxy Mobile IP, proxy-mobile IP are used)
During agreement, also need to set up gateway control session between SGW and PCRF during PDN connection establishment
(GW Control Session), with to SGW transmission bearing binding relevant parameter and QoS(Quality of
Service, service quality) rule (now PGW does not perform bearing binding and carrying level QoS control 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 to PCRF
Control session establishment request message initiate set up process, this request message include ID (IMSI),
APN etc.；PCRF returns gateway control session and sets up response, including QoS rule etc., during being somebody's turn to do
PCRF may ask CAMEL-Subscription-Information to SPR；
Step 302:SGW sends agent binding request message to PGW, between SGW and PGW
Setting up PMIP tunnel, PGW initiates IP-CAN session establishment process to PCRF, it is thus achieved that PCRF issues
PCC rule；
Step 303:PGW returns agent binding response message to SGW.
According to agreement 3GPP TS23.203, there is same subscriber mark and the gateway control meeting of APN
Words correspond to same PDN with IP-CAN session and are connected.
According to current specification, PGW needs to provide ID, PCRF when PCRF request strategy
ID obtains CAMEL-Subscription-Information from SPR, conversate association etc. to be also required to use, and LTE core network
In, ID is the UE NAI of IMSI structure.
3GPP R10 and R11 stage are not supported to connect to LIPA or SIPTO to provide dynamic PCC rule,
But in order to provide preferably QoS to experience to the user accessing local network in follow-up evolution, need to support
To locally-attached policy control, i.e. PCRF needs to issue PCC rule to LGW.Due to LGW not
Belong to the entity in core net, the IMSI of UE is passed to LGW and will there is security threat, therefore core
IMSI will not be passed to LGW by net node, but, if cannot be from LGW according to existing protocol PCRF
Get ID, just cannot ask CAMEL-Subscription-Information to SPR, also cannot carry out PCC rule and issue.
