Long-time when inactive as UE, eNodeB will initiate Release radio resource process, be released to the user plane bearer resource on the S1 interface between radio open bearing resource and eNodeB and the SGW that UE distributes, and after this UE enters Idle state.When UE is in the time that Idle state will send data, eNodeB need to, with MME alternately to revert to the bearing resource of UE distribution, comprise the user plane bearer resource of the S1 interface between empty port load-supporting resource, eNodeB and the SGW on eNodeB.
Fig. 2 is the recovery flow chart that UE is attached to the bearing resource in the time that Idle state (RRC-IDLE state) will be initiated transmitting uplink data after network, when UE is in Idle state, will for example, send data to far-end (application server) time, UE must first set up RRC and connect, and returns to connected state.The recovery flow process of bearing resource when above-mentioned initiation transmitting uplink data comprises the following steps:
S201, UE sends RRC connection request (RRC Connection Request) message to eNodeB, wherein carries the identification information of UE, uses interim mobile signatory mark (S-TMSI, S-Temporary Mobile Subscriber Identity) here.
Under Idle state, it is that SRB0 initiates RRC connection request message that UE utilizes #0 Signaling Radio Bearer resource (SRB, Signaling Radio Bearer).SRB0 is shared Signaling Radio Bearer resource, and the message capacity of designed every UE is very little, and general is carried the most necessary cell for initiating initial RRC message, and as the ID of UE, the ID that here UE provides is S-TMSI.
S202, eNodeB receives after RRC connection request message, sends RRC connect foundation (RRC Connection Setup) message to UE.
This message is used to indicate UE, and to set up #1 Signaling Radio Bearer be SRB1, and SRB1, based on every user assignment, can carry the NAS signaling of certain length.When distributing after SRB1, UE can initiate NAS message with SRB1 Signaling Radio Bearer.
S203, UE sends RRC connection to eNodeB and has set up (RRC Connection Setup Complete) message.In this message, UE carries Non-Access Stratum (NAS, the Non Access Stratum) message that will send.Here, the entrained NAS message of UE is service request (SR, Service Request) message.
In this step, UE sends NAS message with SRB1 Signaling Radio Bearer.Itself also has certain capacity limit SRB1 Signaling Radio Bearer, can not make for sending large NAS message.In subsequent step, it is SRB2 that eNodeB can indicate UE to set up #2 Signaling Radio Bearer, and Data Radio Bearer (DRB, Data Radio Bearer), and these two kinds of radio bearers can carry the NAS message that capacity is larger.DRB also flows for transmission of IP data conventionally.
S204, eNodeB receives after the RRC connection setup complete message of UE, obtains NAS message wherein, NAS message is encapsulated in initial UE transmission (Initial UE Transfer) message of S1 interface, sends to MME.The NAS message that all UE send, is all passed through MME by eNodeB.
S205, MME receives after service request (Service Request) message of UE transmission, and UE is proceeded to connected state (ECM-CONNECTED).Meanwhile, MME sends initialization context request (Initial Context Request) message to eNodeB, comprises the information such as SGW address, the wireless capability of UE that safe key, EPS bearer context information, the UE of UE are assigned with in this message.
S206, eNodeB initiates safe mode to UE and sets up (Security Mode Command) message, requires UE encryption method to transmit follow-up signaling and data.
When eNodeB receives after initialization UE context request (the Initial UE Context Request) message of S205 step MME transmission, eNodeB comes to set up and ask to UE initiation safe mode with safe key wherein.
S207, UE replys safe mode to eNodeB and has set up (Security Mode Complete) message, represents that safe mode request receives, and safe mode has been set up.,, between UE and network, send signaling and data with cipher mode thereafter.
S208, eNodeB sends RRC to UE and connects reconfiguration request (RRC Connection Reconfiguration Request) message, wherein carries concrete radio bearer (RAB, Radio Access Bearer) information.
By this RAB information, eNodeB requires UE to set up specified radio bearer, and these radio bearers specifically comprise that #2 Signaling Radio Bearer is SRB2, and several Data Radio Bearer DRB, and the core net carrying of these DRB and UE is corresponding one by one.
S209, UE sends RRC connection to eNodeB and has reshuffled (RRC Connection Reconfiguration Complete) message, shows that radio bearer configuration completes.
After S209 step is carried out, UE can carry out the NAS message that initiation capacity is larger with SRB2; Can also send up IP traffic, this IP traffic is sent to the corresponding SGW of UE by eNodeB, and SGW further sends to PGW.
S210, the RRC connection that receives UE transmission has been reshuffled after message, and eNodeB returns to initial context configuration response (Initial Context Setup Response) message to MME.
S211, MME receives after the initial context configuration response message of eNodeB transmission, sends bearing modification request (Modify Bearer Request) message to SGW/PGW.
In this step, MME modifies to carrying to the reception condition notice SGW/PGW of carrying according to UE/eNodeB.This message allows SGW recover the bearing resource of the S1-U between eNodeB simultaneously.
S212, SGW/PGW returns to bearing modification response (Modify Bearer Response) message to MME.
After step S212, SGW can receive the up IP packet that UE sends, and the up IP data packet receiving is transmitted to PGW.
S213, receives at eNodeB after the RRC request of UE, and eNodeB is that UE arranges a deactivation timer, after timer exceeds the time limit, if inertia of UE triggers resource dispose procedure.
S214, the UE deactivation timer on eNodeB expires, UE inertia, eNodeB initiates UE context releasing request (the UE Context Release Request) message on S1 interface to MME.
S215, MME receives after UE context releasing request (the UE Context Release Request) message of eNodeB initiation, sends and discharges access bearer request (Release Access Bearer Request) message to SGW.
S216, SGW has discharged after the carrying of the S1-U interface between eNodeB, returns and discharges access bearer response (Release Access bearer Response) message to MME.
S217, MME sends UE context release command (UE Context Release Command) message to eNodeB.
S218, eNodeB receives after UE context release command (the UE Context Release Command) message of MME, if UE current can and, send radio bearer to UE and discharge (RRC Connection Release) message, eNodeB discharges the contextual information of UE on the other hand.
S219, eNodeB returns to UE context to MME and has discharged (UE Context Release Complete) message;
Through step S214 ~ step S219, when after UE inertia, eNodeB is by the bearer context of the radio bearer of release UE, UE context, S1-U interface, and MME will discharge the context of UE and UE be inserted to Idle state, and SGW will discharge the bearer context of S1-U interface.
Fig. 2 shows UE and enters into connected state from Idle state, and recovering bearing resource is initiated transfer of data, and the flow process that finally enters again Idle state.In this flow process, for IP data being sent to SGW, first eNodeB need to search out SGW and recover the data transmission tunnel between SGW, and this bearer related information that needs eNodeB and MME alternately and obtain SGW and S1 interface from MME.When great amount of terminals is initiated small data transmission continually, and sending enter Idle state very soon again after small data transmission in the situation that, the flow process shown in Fig. 2 is easy to cause network signal to overload, and easily causes the congested of control network element.On the other hand, the data traffic that these terminals send enters the caused signaling traffic of connected state much smaller than these terminals from Idle state, has caused the efficiency of system extremely low.
