Description
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of method and apparatus of deleting bearing.
Background technology
In the evolved packet system (EPS) of third generation collaborative project, adopted new core network architecture, the user mobility control and management entity that the enhancing data transfer rate Radio Access Network (UTRAN/GERAN) of universal terrestrial access network/global system for mobile communications in this core network architecture/global system for mobile communications evolution and two kinds of connecting systems of evolved universal terrestrial radio access network (E-UTRAN) are corresponding respectively is that service universal packet wireless business affair service node SGSN and Mobility Management Entity MME are common the existence.In order to be adapted to the user mobility management under the new core network architecture, a kind of idle state signaling optimization (ISR) technology has been proposed in the evolved packet system.The signaling amount of mobility management process when the user terminal (UE) that this technology can reduce idle condition resides at the borderline region of UTRAN/GERAN and two kinds of connecting systems of E-TURAN, described idle condition are meant between UE and the pairing user mobile control management entity in current resident district does not have the signaling of Non-Access Stratum to be connected.When the ISR of UE function is activated, UE will be registered on the corresponding respectively user mobile control management entity of two kinds of connecting systems of UTRAN/GERAN and E-TURAN simultaneously, be SGSN and MME, at this moment, the gateway of UE (Serving GW) also will keep GTP control plane (the GTP Control of S3 interface and S11 interface simultaneously with described SGSN and MME, GTP-C) connect, promptly the GTP-C of two interfaces connects.After activating the ISR function, the UE that is in idle condition distributes between the route district of UE and a plurality of tracking areas that MME distributes to UE when mobile at SGSN, need not to do general Routing Area Update or general tracing section updating operation, can avoid UE issuable frequent route district or tracing section updating operation when mobile between the zone of MME and SGSN management thus, reduce space interface signaling.
After the ISR of UE function is activated, if Serving GW and grouped data network gateway (Packet Data Network GateWay, PDN GW) uses the general packet radio service gprs tunnel protocol between, then UE EPS is carried on MME, all preserve corresponding EPS bearer context on Serving GW and the PDN GW, simultaneously on SGSN, also preserve this EPS and carry pairing packet data protocol (PDP) context, and after this need MME and SGSN on EPS bearer context and PDP Context, to keep synchronous.For example, when UE has activated a new EPS carrying in the E-UTRAN connecting system after, when getting back to the UTRAN/GERAN connecting system afterwards, SGSN will set up corresponding PDP Context by the synchronous mode of context; Carry when UE has deleted an EPS in the E-UTRAN connecting system, when getting back to UTRAN/GERAN afterwards, SGSN will delete corresponding PDP Context by the synchronous mode of context; The QoS of a PDP Context that inserts at UTRAN/GERAN as UE has been modified, and when UE gets back to E-UTRAN afterwards, MME will revise the QoS of the EPS bearer context of correspondence by the synchronous mode of context.In addition, when UE during in connection status its ISR function by deexcitation after, the ISR function that the active user's mobile management controlled entity MME of UE or SGSN will notify this UE of Serving GW is by deexcitation, and Serving GW will delete pairing evolution session management of another user mobility management control entity (ESM) or session management (SM) context that self preserves.For example, when UE was in connection status, the ISR function of this UE of its active user's mobile management controlled entity MME notice Serving GW was during by deexcitation, and Serving GW will delete the pairing SM context of SGSN of its preservation.
Existing EPS system has provided the method for the deletion EPS carrying of being initiated by PDN GW.In the method, PDN GW is by sending the deleting bearing request to Serving GW, and Serving GW will move the control and management entity and finish corresponding deleting bearing processing according to the active user of deleting bearing request triggering UE.But the ISR function that this method is only applicable to UE inactive I SR function or UE is by the ISR function of deexcitation or the UE situation of back UE when being in connection status that be activated.Because, when the ISR function of UE inactive I SR function or UE during by deexcitation, only there is a user mobility management control entity to serve this UE, corresponding, also have only a GTP-C to be connected between the user mobility management control entity of this UE and the Serving GW of this UE.When after the ISR of UE function is activated, being in connection status, this UE is that active user's mobile management controlled entity keeps the signaling of Non-Access Stratum to be connected with its current resident area relative user mobility management control entity only, and GTP-U connection that this moment, Serving GW can be by judging the S1U interface and the notice of SGSN know that active user's mobile management controlled entity that this UE is in connection status and this UE is MME or SGSN.Therefore, in these cases, adopt the method for existing deletion EPS carrying, Serving GW can determine that the active user's mobility control and management entity to UE sends the deleting bearing request message and triggers it and finish corresponding deleting bearing and handle.But, when after the ISR of UE function is activated, being in idle condition, because UE is connected with the signaling that MME does not all set up Non-Access Stratum with SGSN, the Serving GW of UE has all kept GTP-C to be connected with SGSN and MME, therefore Serving GW can't determine to trigger the processing which user mobility control and management entity is deleted the EPS carrying, and after guaranteeing to delete the EPS carrying, it is synchronous that MME and SGSN keep on EPS bearer context and PDP Context.If Serving GW just sends deleting bearing request message or deletion PDP Context request message to SGSN, and do not send the deleting bearing request message to MME, after SGSN receives message, find that UE is in idle condition, will be not can paging UE, and the EPS bearer context of deletion UE in its SM context just; Though realized between SGSN and the Serving GW like this on the EPS loaded state synchronously, but MME and Serving GW and SGSN do not realize on the EPS loaded state synchronously, be that ESM context on the MME does not obtain upgrading, if UE is positioned at E-UTRAN at this moment, even and realized the synchronous of EPS carrying by the tracing section updating process between UE and the MME, but because of the ESM context of MME does not obtain upgrading, MME does not know that described EPS carrying is deleted, so UE can not realize synchronous in the EPS carrying of UE and network by the tracing section updating process.Therefore, the method for existing deleting bearing of being initiated by PDN GW is not suitable for the ISR function back UE that is activated and is in the situation of idle condition.
In addition, when using proxy-mobile IP (PMIP) agreement between Serving GW and the PDN GW, strategy also can trigger gateway (Serving GW) with charging rule functions (PCRF) and initiate the deleting bearing process.Same reason, the method for existing deleting bearing of being initiated by PCRF are not suitable for the ISR function back UE that is activated and are in the situation of idle condition.
In sum, the method for existing deleting bearing of being initiated by PDN GW or PCRF is not suitable for the ISR function back UE that is activated and is in the situation of idle condition.
