Step 8, if used PCRF in the network, then PGW will carry out alternately to obtain the PCC rule with PCRF.(Evolved Packet System EPS) carries, and then uses predefined PCC rule in PGW for acquiescence evolved packet system to be set up.
Step 9, PGW returns one to SGW and creates conversational response message, and this message comprises user plane PGW address and TEID, chain of command PGW TEID, parameters such as PDN type, PDN address, protocol configuration option.
Step 10, SGW returns one to MME and creates conversational response message, and message comprises PDN type, PDN address, user plane SGW address and TEID, chain of command SGW TEID, EPS bearing identification symbol, PGW address etc.
Step 11, MME sends one to eNB and adheres to and accept message.If MME has distributed new global unique user's temporary mark (GUTI); Then the GUTI parameter also will be included in this message, and it is that initial context is set up in request (Initial Context Setup Request) message that this message is included in a S1-MME message.
Step 12, eNB sends RRC to UE and connects reconfiguration message, comprises in this RRC connection reconfiguration message to adhere to accept message (wherein carrying S-TMSI, PDN address, tracking area (TA) tabulation and PDN address information).
Step 13, UE sends the RRC connection to eNB and reshuffles completion message.
Step 14, eNB sends initial context message to MME, and this message comprises TEID and the eNB of the eNB downlink transfer address at S1-U interface.
Step 15, UE sends direct-sending message to eNB, comprises in this message to adhere to completion message.
Step 16, eNB transmits to adhere to and accomplishes message to MME.On the S1-MME reference point, it is that initial context is provided with in the completion message that this message is included in chain of command message, has also comprised TEID and the eNB address of eNB simultaneously in the chain of command message.
UE from adhere to accept to obtain the message PDN address information after, just can send the upstream data bag and give eNB, eNB sends to SGW and PGW through the address, tunnel with this packet subsequently.
Step 17, MME sends a bearer update request message to SGW.
Step 18 is not switched indication if in step 17, carry in the bearer update request message, then directly jumps to step 20.Switch indication if carry in the bearer update request message, then SGW need send the bearer update request message to PGW.
Step 19 if PGW receives the bearer update request, is then replied the bearer update response to SGW.
In concrete enforcement scene, the formation of INITIAL UE MESSAGE can be referring to agreement 3GPP TS 36.413V9.3.0.The formation of Attach Request message can be referring to agreement 3GPP TS 24.301V9.3.0.
In realizing process of the present invention, the inventor finds to exist in the prior art following technical problem:
In the prior art, when UE does not have attachment removal in advance, when same MME adhered to once more, MME at first can do the integrity protection verification to Attach Request after receiving that S1-MME interface message is Attach Request message again.If the integrity protection verification succeeds then can find user's context according to the GUTI among the Attach Request, and judge when CAMEL-Subscription-Information exists, no longer ask for authentication vector and CAMEL-Subscription-Information to HSS.Usually can not change owing to custom strategies simultaneously, so under signatory constant situation, PCRF can not assign new Qos information yet.
Then, MME needs the original tunnel of deletion earlier, and sets up new tunnel.Deleting the tunnel and setting up in the new tunneling process, need MME, SGW, PGW, four network elements of PCRF to carry out interacting message.Need earlier the tunnel on the S5/8 interface between PGW and the SGW to be deleted the tunnel deletion of again the S11 interface between MME and the SGW being set up.On S11, S5/8 interface, set up new tunnel more afterwards.
