Description

The processing method of user profile and system

Technical field

The present invention relates to the communications field, in particular to a kind of processing method and system of user profile.

Background technology

Third generation partner program (3rd Generation Partnership Project, abbreviate 3GPP as) system architecture (the Evolved Packet System of evolution, abbreviate EPS as) by E-UTRAN (Evolved Universal Terrestrial Radio Access Network, abbreviate the UTRAN of evolution as), mobile management unit (Mobility ManagementEntity, abbreviate MME as), gateway (Serving Gateway, abbreviate S-GW as), grouped data network gateway (Packet Data Network Gateway, abbreviate P-GW as), home subscriber server (Home Subscriber Server, abbreviate HSS as), 3GPP authentication and authorization charging server (abbreviating aaa server as), and other support nodes are formed.

Wherein, E-UTRAN is the Access Network of EPS system, and inside comprises the base station (Evolved NodeB abbreviates eNB as) of many evolution; The packet-based core networks of evolution (EvolvedPacket Core Network abbreviates EPC as) are the core net of EPS, comprise MME, network elements such as S-GW and P-GW; MME is responsible for the chain of command related work; S-GW is the accessing gateway equipment that links to each other with E-UTRAN; P-GW is the borde gateway of EPS and packet data network (Packet Data Network abbreviates PDN as) network, be responsible for PDN access, between EPS and PDN, transmit data; P-GW still is the access data gateway that terminal is passed through 3GPP Access Network and non-3 GPP access network, and is user's face anchor point that terminal is switched between 3GPP access and non-3GPP access.

Third generation partner program 2 (3rd Generation Partnership Project 2, abbreviate 3GPP2 as) (the High Rate Packet Data of high-speed packet system, abbreviate HRPD as), by HRPD-AN (HRPD Access Network, HRPD Access Network), PDSN (packet data serving node, Packet Data Serving Node), HA (home agent, HomeAgent), 3GPP2AAA server (3GPP2 authentication and authorization charging server) and other support nodes form.PDSN is the accessing gateway equipment that links to each other with HRPD-AN, is responsible for user's mobile management, context management, and between HRPD-AN and HA, transmit data, and be responsible for pending datas such as paging are carried out buffer memory; HRPD-AN and HA are respectively Access Network and home agent.

Interconnect (the Connectivity andInterworking) of EPS network support and HRPD network, the intercommunication framework is seen accompanying drawing 1, wherein, in the framework that interconnects, the HRPD technology has upgraded to eHRPD for unified with the EPS network element, renames as HRPD gateway (HRPD Serving Gateway abbreviates HSGW as) behind the PDSN function upgrading, HRPD-AN is called HRPD-eAN (Access Network of evolution, evolvedAccess Network) behind function upgrading.In the intercommunication scene, data anchor point P-GW, no matter current terminal is to insert or insert by the eHRPD Access Network by the E-UTRAN Access Network, the up-downgoing transfer of data must be passed through data gateway P-GW.In order to realize that multimode terminal passes through different connecting system and inserts, and can guarantee that it is the continuity of business that terminal is switched, has increased some interfaces newly: S101 interface, S103 interface and S2a interface in different access systems.The S101 interface is used for terminal transmission pre-registration signaling and hand off signaling when E-UTRAN and the switching of eHRPD system; The S103 interface is used for terminal by E-UTRAN system converting downlink data when the eHRPD system is switched.The S2a interface transmits control and bearer service between HSGW and P-GW, adopt the PMIPv6 agreement.

In the prior art, subscriber equipment (User Equipment abbreviates UE as) is divided into two stages from the E-UTRAN connecting system to the step that the eHRPD connecting system switches:

Phase I, UE detects current E-UTRAN wireless signal and begins to become more weak, the wireless signal of eHRPD is fine, UE is before formally switching to eHRPD, doing pre-registration to the eHRPD system earlier prepares, because terminal is singly to treat terminal (being that terminal can not be opened multiple wireless transmission and reception simultaneously), (analysis of existing procedure is seen below in concrete operations) that the eHRPD signaling of this pre-registration stage is delivered to HRPD-eAN and HSGW through the wireless signal and the S101 interface of encapsulation by E-UTRAN.

After finishing the pre-registration preparation, UE may not switch to the eHRPD system immediately, as long as the wireless signal of E-UTRAN can also prop up the current business of being strong enough to support, UE just can not switch, and like this, UE needs to keep in the pre-registration of eHRPD.

Second stage, UE detects current E-UTRAN signal can not support current business, so formally switch to the eHRPD system.Because UE has had pre-registration in the eHRPD system, UE switches to the eHRPD system and just becomes quick and made things convenient for like this.

The concrete operations of switching can by Fig. 2 and concrete steps analysis show more clear.As shown in Figure 2, the switching flow of UE from E-UTRAN to EPC specifically may further comprise the steps:

201.UE be linked into EPC by E-UTRAN, and be in activation (Active) state.

202.UE by measuring wireless signal, it is more weak to detect current E-UTRAN wireless signal, the wireless signal of eHRPD is fine, and decision UE does pre-registration to the eHRPD system and prepares.

203.UE and HRPD-eAN sets up the eHRPD session.

204.HRPD-eAN and set up data channel between the HSGW.Be to set up A10 by the A11 signaling to connect herein.

205.UE insert the authentication and authorization of eHRPD system.

206.UE and set up PDN between the HSGW and connect, finish the reservation of resource and the foundation of carrying.To this step, UE finishes the pre-registration in the eHRPD system.

207.UE after finishing the pre-registration preparation, may not can switch to the eHRPD system immediately, as long as the wireless signal of E-UTRAN can also ensure the business that (support) is current, UE just can not switch, therefore, eHRPD need keep the pre-registration of UE.

Need explanation, UE from the time interval that pre-registration is accomplished between the formal switching be uncertain, so pre-registration to refresh and keep the duration also be uncertain.

208. the signal that detects E-UTRAN as UE is not enough to support current when professional, UE formally switches to eHRPD from E-UTRAN.

In above processing procedure, signaling is set up in eHRPD session between UE and the HRPD-eAN, authentication and authorization signaling between UE and the HSGW, and the maintenance of PDN establishment of connection signaling and pre-registration to refresh all be to pass through eNB, MME transmits, by the E-UTRAN wireless signal between UE and the eNB, the tunnel signaling between eNB and the MME, the S101 signaling bear between MME and the HRPD-eAN.

Because UE is behind the eHRPD pre-registration, do not switch in the eHRPD system immediately, if during attachment removal, the eHRPD system but confiscates relevant signaling to UE from the EPS system, the HSGW of eHRPD system also will keep the pre-registration of UE and relevant context with eAN.Because UE is from the EPS attachment removal, pre-registration can not get upgrading timely, adheres to again even work as terminal, these pre-registration are useless, need rebulid context, like this, just be the resource of eHRPD system of having preserved some useless information wastes.Certainly, system exists corresponding exception handling can delete these pre-registration certainly behind certain hour, but as abnormity processing, generally to there be timer to go control, before timer does not expire, these information still are occupying system resources, and the operation of the attachment removal than UE from eHRPD, all contextual informations relevant with UE will be deleted by the eHRPD system, for the uniformity that guarantees to operate, under this scene, that is: UE is behind the eHRPD pre-registration, UE do not switch to immediately in the eHRPD system, if during attachment removal, should notify the contextual information of eHRPD system-kill correspondence from the EPS system.

When during to scene that the E-UTRAN connecting system switches, also there is same problem from the eHRPD connecting system in UE.Fig. 3 is the flow chart that is switched to E-UTRAN by eHRPD according to the UE of correlation technique, and as shown in Figure 3, this handling process may further comprise the steps:

301.UE be linked into EPC by eHRPD, and be in activation (Active) state;

302.UE by measuring wireless signal, it is more weak to detect current eHRPD wireless signal, the wireless signal of E-UTRAN is fine, and decision UE does pre-registration to the E-UTRAN system and prepares;

303.UE send " adhering to request " to MME.

304.UE insert the authentication and authorization of eHRPD system.

Upgrade 305.MME send the address, and obtain up-to-date user signing contract information to HSS/AAA.

Different with S-GW 306.MME " carrying is set up and asked/reply " signaling, notice S-GW sets up the carrying that needs;

Finish 307. adhere to.To this step, UE finishes the pre-registration in the E-UTRAN system, and this moment, MME will preserve the pre-registration contexts such as authentication information, positional information, beared information of UE, and S-GW also will keep the bearer context of this UE.

308.UE after finishing the pre-registration preparation, may not can switch to goal systems immediately, therefore, the E-UTRAN system need keep the pre-registration of UE;

309. the signal that detects eHRPD as UE is not enough to support current when professional, UE formally switches to E-UTRAN from eHRPD.

In above processing procedure, the signaling between UE and the MME all is to transmit by HRPD-eAN, by the eHRPD wireless signal between UE and the HRPD-eAN, the S101 signaling bear between MME and the HRPD-eAN.

UE has carried out pre-registration by the wireless signal of eHRPD to the EPS system, and the contextual information of pre-registration has been kept at the EPS system, if it is preceding just from the attachment removal of eHRPD system that UE does not also formally switch to the EPS system, do not delete the contextual technology of the pre-registration of this UE in the EPS system so in the prior art yet.

Announcing above-mentioned analysis can draw, and the pre-registration of UE can not get handling timely, is the useless information of the UE that preserves attachment removal, has wasted the resource of system.
