Description
Technical field
The present invention relates to network technology, relate in particular to a kind of method for selecting gateway during for subscriber equipment access 3GPP network, home subscribed services device, select subscriber equipment, the packet data gateway of evolution and the block data system of evolution of gateway when accessing the 3GPP network.
Background technology
The block data system of evolution (Evolved Packet System, EPS, the block data system of evolution) support to utilize non-3GPP IP(3rd Generation Partnership Project Internet Protocol, 3GPP IP, the 3rd Generation Partnership Project Internet Protocol) Access Network access 3GPP(3rdGeneration Partnership Project, 3GPP, 3rd Generation Partnership Project) packet data core network of evolution (Evolved Packet Core, EPC, the packet data core network of evolution), to improve the coverage of EPS, reduce the load of 3GPP Access Network simultaneously.Whether authentication, licensing process that the 3GPP core net adopts according to non-3GPP IP Access Network meet the requirement of 3GPP to fail safe, judge that non-3GPP IP Access Network is trusted network or trustless network.
When fly-by-night non-3GPP IP Access Network access 3GPP EPC, existing gateway selects mechanism not consider subscriber equipment (User Equipment, UE, subscriber equipment) position, gateway distance relation each other.When UE accesses 3GPP EPC by fly-by-night non-3GPP IP Access Network, UE is to packet data network gateway (Packet Data Network Gateway, PDN GW, packet data network gateway) Route Selection comprises packet data gateway (the Evolved Packet Data Gateway of evolution, ePDG, the packet data gateway of evolution) select and PDN GW selection.
Existing 3GPP 23.402 agreements adopt ePDG and PDN GW separately to select mechanism.
Wherein, ePDG selects to comprise: in non-3 GPP access network access authentication/licensing process, UE utilizes the gateway selecting function on UE, and according to ePDG FQDN(Full Qualified Domain Name, FQDN, universe name) from home domain name system server (Domain Name System Server, DNS server, domain name system server) obtain ePDG IP(Internet Protocol, IP, Internet Protocol) address list.UE selects randomly an IP address as purpose ePDG IP address from this IP address list.In this process, UE is by the PLMN ID(Public Land Mobile Network ID of network of living in, and public land mobile network identifies) form ePDG FQDN as carrier ID.
Perhaps, ePDG selects to comprise: UE has selected an initial ePDG, and has set up the IPsec tunnel with initial ePDG.IPsec(Internet Protocol Security in UE foundation with initial ePDG, internet protocol secure) tunnel this IPsec tunnel is carried out in 3GPP authentication/licensing process, initial ePDG sends to HSS/AAA server(Home Subscriber Server or Authentication Authorization Accounting, home subscribed services device or authentication/mandate/accounting server by non-3GPP network identity).HSS/AAA server finds the target ePDG nearer apart from this UE, and target ePDG selection information is sent to initial ePDG.Initial ePDG is transmitted to UE by target ePDG information.UE sets up the IPsec tunnel with target ePDG, and this tunnel is carried out in the 3GPP network to authentication/mandate.The IPsec tunnel of UE disconnection afterwards and initial ePDG.
PDN GW selects to comprise: the PDN GW selection function on ePDG, in IPsec tunnel authentication/licensing process, is obtained alternately PDN GW with 3GPP AAA Server/Proxy and is selected information, and this selection information offers 3GPP AAA Server/Proxy by HSS.This selection information comprises PDN GW ID(Identity, ID, sign), or comprise APN(Access Point Name, APN) and an indication.Wherein, PDN GW ID comprises FQDN or comprises IP address and APN; Whether this indication explanation PDN GW is to distribute from visit public land mobile network (Visited Public Land Mobile Network, VPLMN, visit public land mobile network).PDN GW selection function on ePDG by with DNS server reciprocal process, gateway selection information is sent to DNS server, and obtains PDN GW IP address from DNS server.
Because PDN GW selects to select to separate to carry out with ePDG, and HSS do not consider the distance relation between ePDG and PDN GW, causes UE-> ePDG-> the route optimum not of PDN GW.For example: UE utilizes existing ePDG to select mechanism to choose the ePDG1 that turns jumping minimum (as 1 time) with the IP of UE, ePDG1 utilizes existing PDN GW to select mechanism to choose the PDN GW1 that turns jumping minimum (as 3 times) with the IP of ePDG1, and now UE turns jumping to 4 IP of the minimum needs of PDN GW1.If existing the IP of ePDG2 and UE to turn and jumping is 2 times, it is 1 time that the IP between ePDG2 and PDN GW2 turns jumping.The prior art of utilizing like this ePDG and PDN GW separately to select just can not be chosen the optimization route between UE and PDN GW.

Step 77:ePDG selects information and DNS server interactive selection to PDN GW according to UE to the PDN GW in the best routing iinformation of PDN GW.
Step 78, ePDG send " IKE v2(internet key exchange Version2, second version of the Internet Key Exchange) " message that has comprised the IP address to UE.
Successfully set up the IPsec tunnel between step 79, UE and ePDG.
Step 710, UE and PDN GW complete the MIPV6 security association and set up and the home address configuration, carry out authentication/mandate between PDN GW and HSS.
Step 711, UE send " Binding Update " message to PDN GW.
Step 712, PDN GW and PCRF set up the IP-CAN session.
Step 713, PDN GW send " binding acknowledgement " message to UE.
Then complete the foundation in IPsec tunnel and DSMIPv6 tunnel, remaining step is the operation in traditional attachment flow.
In the embodiment of the present invention, pass through the sight of S2c interface accessing 3GPP core net for the UE in fly-by-night non-3GPP network, range information between the positional information of the access network that HSS is used according to UE and ePDG and PDN GW, can obtain on the whole the best routing iinformation of subscriber equipment to PDN GW, by best routing iinformation is issued to UE, and UE selects corresponding gateway according to best routing iinformation, realized the best route of UE to PDN GW.
In prior art, UE only forms ePDG FQDN with PLMN ID as foundation, do not consider that the residing Access Network of UE do not consider the residing position of UE, so can't form location comparison ePDG FQDN accurately, thereby the problem that accurate selection ePDG is exerted an influence, and, with respect in prior art, set up the IPsec tunnel between UE and the ePDG that utilizes prior art one to select after, HSS/AAA reselects ePDG.Cause between UE and network carrying out one time the IPsec tunnel establishment procedure more, carry out authentication/licensing process that IPsec tunnel is undertaken by the 3GPP network more, carry out IPsec tunnel delete procedure one time more, the 3GPP core network signalling caused increases, initially adhere to the problem that time delay increases, the embodiment of the present invention has not only been considered the positional information of UE when HSS selects UE to the route of PDN GW, make the HSS can the nearest route optimization of chosen distance UE, more importantly also considered the distance relation between ePDG and PDN GW, make HSS can choose UE to the best route between PDN GW, and for providing ePDG, UE select information and PDN GW to select information.And the embodiment of the present invention completes the best route selection of UE to PDN GW by HSS in the initial access authentication/licensing process of UE, thereby obtain ePDG, select information and PDN GW to select information.Than prior art, reduced by IPsec tunnel establishment procedure, reduced tunnel by 3GPP network authentication/licensing process, reduced IPsec tunnel delete procedure one time, reduced network load.
It should be noted that; the access network that subscriber equipment uses can be also the 3GPP network; when the access network used when subscriber equipment is the 3GPP network; corresponding network configuration, message or signaling etc. can be revised accordingly according to the concrete condition of 3GPP network; the access network that basic invention thinking can be used with reference to subscriber equipment is the situation of each embodiment of non-3GPP network, and this is also in protection scope of the present invention.
