Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of report method and gateway of wireless access type.
Background technology
Existing evolved packet system (EPS, Evolved Packet System) adopts new core network architecture, as shown in Figure 1, comprising: Serving GPRS Support Node (SGSN, Serving GPRSSupport Node), gateway (S-GW, Serving Gateway), Mobility Management Entity (MME, Mobility Management Entity), packet data network gateway (PDN Gateway, Packet DataNetwork Gateway), strategy and charging rule functions (PCRF, Policy and Charging RulesFunction) entity etc.
The EPS system supports a new function: idle state signaling optimization (ISR, Idle State SignalingReduction) function.After the ISR function of SGSN and MME activation UE, will notify the ISR function of this UE of Serving GW to be activated.After the ISR of UE function is activated, this UE just is registered on this SGSN and this MME, at this moment, this UE has two mobile management controlled entities, be SGSN and MME, serve the Serving GW of this UE like this and serve the SGSN of this UE and MME between maintain the GPRS Tunnel Protocol control (GTP-C of S4 interface and S11 interface simultaneously, GPRS TunnelingProtocol Control) connects, promptly two GTP-C connect, this SGSN and this MME also are registered on the home subscriber servers (HSS, Home Subscriber Server) simultaneously.
But, when the ISR of UE function is not activated by the ISR function of deexcitation or UE, the mobile management controlled entity of serving this UE has only one (SGSN or MME), at this moment, maintaining a GTP-C between the Serving GW that serves this UE and this mobile management controlled entity is connected, just when the ISR of UE function is not activated by the ISR function of deexcitation or UE, have only a GTP-C to be connected between the mobile management controlled entity of serving this UE and the Serving GW that serves this UE.
After the ISR of UE function is activated, the EPS carrying (Bearer) of UE is at MME, SGSN, corresponding EPS bearer context (EPS Bearer Context) is all arranged on the Serving GW, and need MME, it is synchronous that SGSN and Serving GW keep on EPS Bearer Context, for example: when UE at evolved universal terrestrial radio access network (E-UTRAN, Evolved Universal Terrestrial RadioAccess Network) activates a new EPS Bearer in, get back to universal terrestrial access network (UTRAN then, Universal Terrestrial Radio Access Network)/the enhancing data transfer rate Radio Access Network (GERAN of GSM/GSM evolution, GSM/EDGE (Enhanced Data rates for GSMEvolution) Radio Access Network) in the time of in, SGSN will set up the EPS Bearer corresponding with this EPS Bearer among the MME by the synchronous mode of Context in SGSN; As UE EPS Bearer of deexcitation in E-UTRAN, when getting back among the UTRAN/GERAN then, SGSN will delete SGSN by the synchronous mode of Context and go up the EPS Bearer corresponding with this EPS Bearer among the MME; Service quality (QoS as the EPS Bearer of UE in UTRAN/GERAN, Quality ofService) has been modified, when getting back among the E-UTRAN then, MME will revise the QoS of EPS Bearer Context corresponding with this EPS Bearer among the SGSN among the MME by the synchronous mode of Context.
When UE is in connection status, its ISR function by deexcitation after, the current mobile management controlled entity of this UE, be currently to set up SGSN or the MME that signaling is connected with this UE, with notification service in the ISR function of this UE of the Serving of this UE GW by deexcitation, this Serving GW will delete the pairing EPS session management context of another mobile management controlled entity (MME or SGSN) (ESM Context, EPS Session Management Context) of this UE.For example, when UE is in when setting up the connection status that signaling is connected with MME, its ISR function by deexcitation after, MME with notification service in the ISR function of this UE of the Serving of this UE GW by deexcitation, this Serving GW will delete the pairing ESM Context of another mobile management controlled entity SGSN of this UE then.
Defined the session management procedure of EPS system in the chapters and sections 5.4 of TS23.401v8.1.0, wherein defined session management procedure all is the session management procedure when UE is in connection status.When UE is in connection status, the Serving GW that serves this UE can will set up the identification information of the wireless access type (RAT Type) of this UE that MME that signaling is connected or SGSN provide with this UE, by bearing binding and event reporting function (BBERF, Bearer Binding and Event Reporting Function) entity reports the PCRF entity, when using the GTP agreement between Serving GW and the PDN GW, BBERF is positioned at PDN GW place, and this moment, the BBERF entity was as PDN GW; When using proxy-mobile IP (PMIP, Proxy Mobile IP) agreement between Serving GW and PDN GW, BBERF is positioned at ServingGW, and at this moment, the BBERF entity is as Serving GW.After this, this PCRF entity can be made corresponding strategy control and charging regulation (PCC Rules) according to the RAT Type of this identification information correspondence, provide this PCC Rules to BBERF then, then BBERF can carry out the management process of EPSBearer according to this PCC Rules.Wherein, the RAT Type identification information that MME provides can only be the type that sign E-UTRAN inserts, and the RAT Type identification information that SGSN provides can be the type that sign UTRAN or GERAN insert.Defined 6 kinds of RAT Type at present, as shown in table 1.
