Description

The information maintenance method of non-seamless WLAN shunt connection, Apparatus and system

Technical field

The present invention relates to wireless communication field, particularly to a kind of non-seamless WLAN shunt connect information maintenance method, Apparatus and system.

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, General Packet Radio System) tunnel protocol) the mobility of S2a interface) working group's research is: when S2a connects When mouth uses GTP agreement, terminal (UE) passes through WLAN access network of network framework and relevant information flow process, as the most attached Process, bearing modification process and handoff procedure etc..

UE uses WLAN to access and is connected to EPC(Evolved Packet Core, the block core of evolution by S2a interface Net) network, for operator, this wlan network is believable access network, is referred to as TWAN(Trusted WLAN (Wireless Local Area Network, WLAN) Access Network, believable WLAN access network), then It is shown in Figure 1 that UE uses WLAN access to be connected to EPC network of network framework, wherein, and the most again can basis inside TWAN Function is divided into WLAN AN(WLAN Access Network, WLAN access network), TWAP(Trusted WLAN AAA Proxy, believable WLAN authentication, authorization, accounting is acted on behalf of) and TWAG(Trusted WLAN Access Gateway, believable WLAN accesses gateway) three parts, shown in Figure 2.

WLANAN is WLANAP(Access Point, access point) set, be made up of one or more WLAN AP, its In, TWAG is default router for UE, is also DHCP(Dynamic Host Configuration Protocol, dynamic State host configuration) Server(server), TWAG Yu PGW(Packet Data Network Gateway, grouped data Net gateway) between communicated by S2a interface, as chain of command and the data surface of UE, access EPC's when TWAN provides for UE During service, TWAG is responsible for being forwarded to the data of UE PDN(Public Data Network, public data network) GW(Gateway, Gateway)；TWAP Yu 3GPP AAA(Authentication, Authorization and Accounting, certification, mandate and Charging) communicated by STa interface between server (Server), for the access authentication procedure of UE, it is responsible at WLANAN And between 3GPPAAA server, forward AAA information.

In 3GPP agreement, a solution of SaMOG system includes: NSWO is set up in the initial attaching process of UE, UE request (Non-Seamless WLAN Offload, non-seamless WLAN shunt) connects or new PDN connects process and UE deactivate The PDN that lives connects or the process of deexcitation NSWO connection.Wherein, it is that the logic between UE and PDN GW connects that PDN connects, and passes through PDN connects the flow of transmission and is required for the route through EPC, just can be sent to external network or be sent to UE；NSWO connects The flow of transmission needs not move through EPC route, directly just can be sent to external network by wlan network or is sent to UE.

In SaMOG system, UE can set up PDN simultaneously and connect and NSWO connection, and 3GPP AAAServer only safeguards that PDN is even The information connect, and do not safeguard and connect relevant information to NSWO.When UE deexcitation the last item PDN connection, NSWO connection is still deposited Time, owing to 3GPP AAA Server not having other contextual informations of UE, 3GPP AAA Server initiation UE is gone note Volume process, in this process, HSS(Home Subscriber Server, home subscriber server) upper from its UE preserved Hereinafter delete the address information of this 3GPP AAA Server.

According to the content of 3GPP TS23.402, when the CAMEL-Subscription-Information of UE changes, HSS will update 3GPP The CAMEL-Subscription-Information of the UE of storage in AAA Server, then 3GPP AAA Server is responsible for updating the label of the UE preserved in TWAN About information.In above-mentioned scene, the address letter of the above-mentioned 3GPP AAA Server of storage in HSS deletes the context of UE After breath, if the CAMEL-Subscription-Information of UE changes, owing to the context of the UE of HSS storage not having above-mentioned 3GPP AAA The address information of Server, so TWAN cannot obtain the new CAMEL-Subscription-Information of UE, can only use old CAMEL-Subscription-Information is that UE carries For service.If the CAMEL-Subscription-Information after this UE updates connects relevant (such as, NSWO connects signing and lost efficacy), due to TWAN to NSWO Can not obtain the new CAMEL-Subscription-Information (i.e. TWAN cannot know that NSWO connects signing and lost efficacy) of UE, TWAN remains as UE and provides NSWO Connection Service.

From the foregoing it can be that in prior art, for establishing the UE that PDN connects and NSWO connects, generally The information that the PDN that in 3GPP AAA Server, only record UE sets up connects, does not record the information that the NSWO of UE foundation connects. After its all PDN set up of UE deexcitation connect, owing to 3GPP AAA Server not storing other contexts of UE Information, then 3GPP AAAServer initiates UE to HSS and goes registration process；After this goes registration process to terminate, upper from UE of HSS Hereinafter delete the IP address of this 3GPP AAA Server.Now, if the NSWO CAMEL-Subscription-Information of UE changes (as due to this The NSWO of UE connects signing and expires, and network no longer provides NSWO to connect for UE), owing to HSS not recording above-mentioned 3GPP AAA The IP address information of Server, HSS cannot update the signing letter relevant to NSWO of the UE of storage in 3GPP AAA Server Ceasing, this causes the CAMEL-Subscription-Information relevant to NSWO of the UE of storage in TWAN to be updated, and therefore TWAN still uses UE old CAMEL-Subscription-Information (the most invalid user signing contract information) be UE provide NSWO Connection Service.

In sum, in prior art, owing to the information relevant to NSWO connection of UE is not entered by 3GPP AAA Server Row is safeguarded, then cause when the NSWO connection status of UE changes, and TWAN uses invalid user signing contract information to provide for UE Service.
