Description
Technical field
The present invention relates to wireless communication field, information maintenance method, Apparatus and system that particularly a kind of non-seamless WLAN shunting connects.
Background technology
3GPP(3rd Generation Partnership Project, third generation partner program) SaMOG(S2a Mobility based On GTP, based on GTP(GPRS Tunnelling Protocol, GPRS(General Packet Radio System, the mobility of S2a interface General Packet Radio System) tunnel protocol)) working group's research is: when S2a interface is used GTP agreement, terminal (UE) is by WLAN access network of network framework and relevant information flow process, as initial attaching process, bearing modification process and handoff procedure etc.
UE is used WLAN access to be connected to EPC(Evolved Packet Core by S2a interface, the packet-based core networks of evolution) network, for operator, this wlan network is believable access network, be referred to as TWAN(Trusted WLAN(Wireless Local Area Network, WLAN (wireless local area network)) Access Network, believable WLAN access network), to use WLAN access to be connected to EPC network of network framework shown in Figure 1 for UE, wherein, TWAN inside further can be divided into WLAN AN(WLAN Access Network according to function again, WLAN access network), TWAP(Trusted WLAN AAA Proxy, believable WLAN authentication, authorize and charging proxy) and TWAG(Trusted WLAN Access Gateway, believable WLAN IAD) three parts, shown in Figure 2.
WLANAN is WLANAP(Access Point, access point) set, by one or more WLAN AP, formed, wherein, TWAG is default router for UE, also be DHCP(Dynamic Host Configuration Protocol, DHCP) Server(server), TWAG and PGW(Packet Data Network Gateway, packet data network gateway) between, by S2a interface, communicate, chain of command and data surface as UE, when TWAN provides the service of access EPC for UE, TWAG is responsible for the data retransmission of UE to PDN(Public Data Network, public data network) GW(Gateway, gateway), TWAP and 3GPP AAA(Authentication, Authorization and Accounting, authentication，authorization，accounting) between server (Server), by STa interface, communicate, for the access authentication procedure of UE, be responsible for forwarding AAA information between WLANAN and 3GPPAAA server.
In 3GPP agreement, a solution of SaMOG system comprises: NSWO(Non-Seamless WLAN Offload is set up in the initial attaching process of UE, UE request, non-seamless WLAN shunting) connect or the process that new PDN connects and the process that UE deexcitation PDN connects or deexcitation NSWO connects.Wherein, it is the logic connection between UE and PDN GW that PDN connects, and the flow that connects transmission by PDN all needs the route through EPC, just can be sent to external network or send to UE; The flow that NSWO connects transmission does not need the route through EPC, directly by wlan network, just can be sent to external network or be sent to UE.
In SaMOG system, UE can set up PDN simultaneously and connect and to be connected with NSWO, and 3GPP AAAServer only safeguards the information of PDN connection, and does not safeguard the information with NSWO join dependency.When UE deexcitation the last item PDN connects and NSWO connects while still existing, owing to there is no other contextual informations of UE in 3GPP AAA Server, 3GPP AAA Server goes initiation UE to registration process, in this process, the address information of HSS(Home Subscriber Server, home subscriber server) deleting this 3GPP AAA Server from the context of the UE of its preservation.
Known according to the content of 3GPP TS23.402, when the CAMEL-Subscription-Information of UE changes, HSS will upgrade the CAMEL-Subscription-Information of the UE storing in 3GPP AAA Server, and then 3GPP AAA Server is responsible for upgrading the CAMEL-Subscription-Information of the UE preserving in TWAN.In above-mentioned scene, after HSS has deleted the address information of the above-mentioned 3GPP AAA Server storing in the context of UE, if the CAMEL-Subscription-Information of UE changes, the address information that there is no above-mentioned 3GPP AAA Server in context due to the UE of HSS storage, so TWAN cannot obtain the new CAMEL-Subscription-Information of UE, can only use old CAMEL-Subscription-Information to provide service for UE.For example, if the CAMEL-Subscription-Information after this UE upgrades and NSWO join dependency are (, NSWO connects signing inefficacy), because TWAN can not obtain the new CAMEL-Subscription-Information (being that TWAN cannot know that NSWO connects signing inefficacy) of UE, TWAN is still for UE provides NSWO Connection Service.
From foregoing, in prior art, for having set up the UE that PDN connection is connected with NSWO, conventionally in 3GPP AAA Server, only record the information of the PDN connection of UE foundation, do not record the information of the NSWO connection of UE foundation.After all PDN of its foundation of UE deexcitation connect, owing to not storing other contextual informations of UE in 3GPP AAA Server, 3GPP AAAServer initiates UE to HSS and goes registration process; At this, go after registration process finishes, HSS deletes the IP address of this 3GPP AAA Server from the context of UE.Now, if the NSWO CAMEL-Subscription-Information of UE changes (as the NSWO due to this UE connects signing expiring, network no longer connects for UE provides NSWO), owing to not recording the IP address information of above-mentioned 3GPP AAA Server in HSS, HSS cannot upgrade the CAMEL-Subscription-Information relevant to NSWO of the UE storing in 3GPP AAA Server, this causes the CAMEL-Subscription-Information relevant to NSWO of the UE that stores in TWAN to be upgraded, so TWAN is still used the old CAMEL-Subscription-Information of UE (being invalid user signing contract information) to provide NSWO Connection Service for UE.
In sum, in prior art, because 3GPP AAA Server does not safeguard the information with NSWO join dependency of UE, cause when the NSWO of UE connection status changes, TWAN is used invalid user signing contract information to provide service for UE.
