Description

User equipment access method, Apparatus and system
Technical field
The present invention relates to the communications field, in particular to a kind of user equipment access method, Apparatus and system.
Background technology
In order to keep the strong competitiveness of 3-G (Generation Three mobile communication system), must improve its network performance and reduce networking and operation cost at moving communicating field.Therefore; Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) the standardization effort group just endeavouring to study core network system evolution---packet-based core networks (the Evolved Packet Core of evolution of future generation at present; Abbreviate EPC as), purpose is can be for the user provides higher transmission rate, shorter propagation delay time.The EPC system supports the access of the universal land radio access web (Evolved Universal Terrestrial Radio Access Network abbreviates E-UTRAN as) of evolution; The EPC system supports the access of Non-3GPP Access Network, for example, and WLAN (Wireless Local Area Network abbreviates WLAN as) Access Network.
Fig. 1 is the system architecture diagram of the grouping system (Evolved Packet System abbreviates EPS as) of evolution.As shown in Figure 1, subscriber equipment (User Equipment abbreviates UE as) is under the non-roaming situation, and UE can insert the sketch map of EPC through mistrustful Non-3GPP Access Network access EPC and UE through E-UTRAN.
Network element shown in Figure 1 also comprises: mobile management unit (Mobility Management Entity; 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 (3GPP aaa server), the packet data gateway of evolution (Evolved Packet Data Gateway abbreviates ePDG as).Wherein, MME is responsible for mobile management, the processing of Non-Access Stratum (Non-Access Stratum abbreviates NAS as) signaling, user's chain of command related works such as the contextual management of mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and P-GW, transmits data; P-GW is the borde gateway of the IP operation that provides of 3GPP EPS and public land mobile network (Home Public Land Mobile Network abbreviates HPLMN as), be responsible for IP operation access, between EPS and IP operation net, transmit data.
Mistrustful non-3 GPP access network (Untrusted Non 3GPP Access): do not have trusting relationship between 3GPP network and this non-3GPP connecting system, non-3GPP connecting system must at first insert the ePDG of 3GPP network, inserts P-GW through the S2b interface again.At this moment set up a secure tunnel between UE and the ePDG, guarantee the safe transmission of data between UE and the 3GPP network.Wherein, the S2b interface uses proxy mobile IP protocol sixth version (Proxy Mobile Internet Protocol version 6 abbreviates PMIPv6 as) or GPRS Tunnel Protocol (GPRS Tunnel Protocol abbreviates GTP as).
(Session Initiation Protocol SIP) can be used for setting up Session initiation Protocol, the calling between the user of change and termination IP based network.
In Fig. 1, use the NAS agreement between UE and the MME, mainly be used for supporting mobile management and the session management of UE, wherein, session management comprises: set up and keep UE and connect to the IP between the PGW.
Fig. 2 is the chain of command protocol stack sketch map between UE and the ePDG in the correlation technique.Wherein, L2/L1 is data link layer and physical layer; IPv4/v6 is the IP layer; Internet key change second edition (Internet Key Exchange Version 2 abbreviates IKEv2 as) is used between UE and ePDG arranging key and set up IP safety (IP security abbreviates IPSec as) tunnel.
Fig. 3 is that UE passes through the flow chart that mistrustful non-3 GPP access network inserts EPC.As shown in Figure 3, this flow process mainly comprises following processing:
Set up Security Association between step S302:ePDG and the UE, carry out safety certification between EPC network and the UE simultaneously;
Step S304:ePDG accomplishes after the authentication to UE, initiates the PDN connection to PGW and sets up request message.
Wherein, when S2b used PMIPv6, this message was agent binding update, and PGW sends the agent binding affirmation after receiving this message, wherein is included as this UE addresses distributed; When S2b used GTP, this message was for setting up conversation request, and the session answer was set up in transmission after PGW received this message, wherein comprised this UE addresses distributed.
Step S306:ePDG sends the above-mentioned PGW IP address allocated of IKEv2 message informing UE, accomplishes the foundation of ipsec tunnel.
When UE inserts the 3GPP network, for some Packet Data Network (packet data network abbreviates PDN as); UE need carry out the external authentication in this PDN network, and this moment, UE need be with authentication information (for example, usemame/password etc.); Through protocol configuration option (protocol configuration option; Abbreviate PCO as) issue PGW, PGW and outside PDN carry out authentication to this user afterwards, and authentication result is returned to UE.
Yet, in the correlation technique, because the limitation of IKEv2 agreement; In some cases; Subscriber equipment can't adopt the IKEv2 agreement to access to the packet data gateway of evolution, thereby makes the information of part 3GPP network needs to obtain through the IKEv2 agreement, causes partial function to realize.
For example: when UE inserted the 3GPP network through Fig. 2 mode, UE can't send to ePDG with external authentication information in the step 301, so PGW can't get access to external authentication information, caused carrying out the authentication of outside PDN network to the user.
For example; When UE when E-UTRAN and WLAN insert EPC simultaneously; If keep UE to use same IP address to insert same outside PDN network, present IKEv2 agreement can't hope that IP stream (IP flow) information that inserts at WLAN issues ePDG with the user, so network can't be realized the migration of flowing.
Summary of the invention
Information to part 3GPP network in the correlation technique needs can't be obtained through the IKEv2 agreement; The problem that partial function can't be realized and propose the present invention; For this reason, main purpose of the present invention is to provide a kind of improved user equipment access method and system, one of to address the above problem at least.
