Abstract

The invention provides a method for a 3GPP user obtaining QoS signing in a WLAN. According to the method, for the problem that QoS parameters signed by the user in a 3GPPHLR/HSS cannot be obtained after the 3GPP user is in roam or the WLAN is switched to, WLAN address information is used for mapping an APN of the 3GPP user, AAA obtains QoS parameters corresponding to the APN of the 3GPP user through the HLN or the HSS, and transmits the signed parameter pairs of the APN of the 3GPP user and the QoS to WLANAN where the 3GPP user locates, and therefore the experience of the 3GPP user surfing the Internet through the WLAN is improved effectively.

Description

In a kind of wlan network, 3GPP user obtains the signing method of QoS

Technical field

The invention belongs to the mobile communication technology field, be specifically related to 3GPP user in a kind of wlan network and obtain the signing method of QoS.

Background technology

The non-3GPP network insertion 3GPP EPC(Evolved Packet Core defined in the 4G standard criterion, the packet-based core networks of evolution) as shown in Figure 1 topological structure.In actual application, CDMA2000 HRPD network, wlan network etc., be linked in the EPC network of 4G with the non-3GPP network access mode of credit or non-credit.Wherein, because 3GPP user accesses EPC by wlan network, can effectively reduce the user to the taking of 3GPP Radio Resource, shunt heavy user data traffic, improve user's experiences of surfing the Net, thereby by large-scale the deployment and employing in each large operator.

In Practical Project is disposed, the user accesses the topological structure of 4G by wlan network, as shown in Figure 2: 3GPP user roams or is switched in wlan network, through WLAN AN(WLAN Access Network, the WLAN Access Network) with AAA (Authentication, Authorization, Accounting, authentication and authorization charging) the Radius interface between server, initiate authentication authorization request to aaa server.It is mutual that AAA passes through D '/Gr ' interface or Wx/SWx interface and HLR or HSS, and the user is authenticated.After authentication was passed through, HLR or HSS can license to AAA to the information that the user contracts, and through WLAN AN, license to the user by AAA.Now, this 3GPP user just can directly go up Internet by WLAN AN.Although user or 3GPP user, do not need to use wireless, the cable resource of 3GPP to carry out data service, thereby effectively shunted the load of 3GPP network.

In this process, 3GPP user's CAMEL-Subscription-Information, especially service quality QoS parameter information, the HLR(Home Location Reister that is kept at 3GPP, the user attaching location register)/HSS(Home Subscriber Server, user's subscribed services device), user roaming or when being switched to wlan network and carrying out Certificate Authority, owing in authentication request message, not carrying APN(Access Point Name, the access point name) information, AAA can't accurately license to 3GPP user from the qos parameter of selecting the user to use the authorization message of HLR/HSS, thereby cause the user can not use oneself signing qos parameter, reduce user's experience.

Ways of addressing this issue is the fixing QoS of configuration in local focus or WLAN Access Network WLAN AN at present, no matter what the user contracted in HLR/HSS is what, all adopt local configuration, this method greatly reduces user's experience, and underaction.

Summary of the invention

Technical problem to be solved by this invention is in order to overcome the deficiencies in the prior art, proposes 3GPP user in a kind of wlan network and obtains the signing method of QoS.Described method is the SSID(Service Set Identifier of the WLAN carried in authentication request message, service set) or the MAC Address of focus Hotspot be mapped as corresponding APN, then AAA according to this APN from the authorization message of HLR/HSS, matching corresponding QoS CAMEL-Subscription-Information, license to the 3GPP user who roams or be switched to wlan network and use, thereby the online after improving 3GPP user's roaming or being switched to wlan network is experienced.

The present invention, for solving the problems of the technologies described above, adopts following technical scheme:

In a kind of wlan network, 3GPP user obtains the signing method of QoS, comprises step as follows:

Steps A, 3GPP user roaming or be switched to the zone that the WLAN focus covers after, the 3GPP user equipment (UE) sends the WLAN authentication request message to WLAN AN, the WLAN authentication request message comprises 3GPP User Identity ID;

Step B, after WLAN AN receives the WLAN authentication request message, be encapsulated in 3GPP User Identity ID and WLAN address information in the aaa authentication request message, sends to the 3GPP aaa server;

Step C, after the 3GPP aaa server is received the aaa authentication request message, initiate authentication to HLR or HSS, and described 3GPP user is authenticated; After authentication was passed through, HLR or HSS transmitted 3GPP user's CAMEL-Subscription-Information to the 3GPP aaa server, and described 3GPP user's CAMEL-Subscription-Information comprises APN and the QoS information corresponding with APN;

Step D, 3GPP aaa server, according to the preset WLAN address information in this locality and the mapping relations of APN, obtain the APN of described 3GPP user correspondence in the 3GPP network;

From described 3GPP user's CAMEL-Subscription-Information, the 3GPP aaa server obtains 3GPP user's QoS CAMEL-Subscription-Information according to APN, response aaa authentication request message, send the aaa authentication acknowledge message to WLAN AN, and described aaa authentication acknowledge message comprises described 3GPP user's QoS CAMEL-Subscription-Information;

Step e, after WLAN AN received the aaa authentication acknowledge message, WLAN AN response WLAN authentication request message, sent WLAN authenticate-acknowledge message to the 3GPP user equipment (UE), informs 3GPP user equipment (UE) authentication success, obtained correct QoS CAMEL-Subscription-Information;

After step F, 3GPP user equipment (UE) receive WLAN authenticate-acknowledge message, judge authentication success, and by the direct accesses network of WLAN AN.

In step D, the MAC Address that described WLAN address information is SSID or focus or the IP address of WLAN AN or WLAN AN sign.

Further, if can't obtain SSID or the MAC Address of focus or IP address or the WLAN AN sign of WLAN AN of WLAN, directly use the APN of acquiescence.

The invention has the beneficial effects as follows: proposed 3GPP user in a kind of wlan network and obtained the signing method of QoS.Described method is for after 3GPP user's roaming or being switched to wlan network, can't obtain the qos parameter problem of oneself contracting in 3GPP HLR/HSS, adopt WLAN address information mapping 3GPP user's APN, and then AAA obtains the signing parameter of the QoS corresponding with 3GPP user APN by HLR or HSS, and this 3GPP user's APN and QoS are contracted to parameter to sending the WLAN AN at 3GPP user place to, thereby effectively improved the experience that 3GPP user surfs the Net by WLAN.
