Description

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

Technical field

The invention belongs to 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-3 GPP network access 3GPPEPC(EvolvedPacketCore defined in 4G standard criterion, the packet-based core networks of evolution) topological structure as shown in Figure 1.In the application of reality, CDMA2000HRPD network, wlan network etc., be linked in the EPC network of 4G with the non-3 GPP network access way of credit or non-credit.Wherein, because 3GPP user accesses EPC by wlan network, effectively can reduce user's taking 3GPP Radio Resource, shunt heavy user data traffic, improve user and to surf the Net experiences, thus be disposed and employing by large-scale in Ge great operator.

In Practical Project is disposed, user is by the topological structure of wlan network access 4G, as shown in Figure 2: 3GPP user roams or is switched in wlan network, through WLANAN(WLANAccessNetwork, WLAN Access Network) and AAA(Authentication, Authorization, Accounting, authentication and authorization charging) 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, carries out certification to user.After certification is passed through, the authorizing information that HLR or HSS can contract user, to AAA, licenses to user by AAA through WLANAN.Now, this 3GPP user just directly can go up Internet by WLANAN.Although user or 3GPP user, do not need to use wireless, the cable resource of 3GPP to carry out data service, thus effectively shunted the load of 3GPP network.

In this process, the CAMEL-Subscription-Information of 3GPP user, especially service quality QoS parameter information, the HLR(HomeLocationReister being kept at 3GPP, user attaching location register)/HSS(HomeSubscriberServer, user's subscribed services device) in, user's roaming or be switched to wlan network when carrying out Certificate Authority, owing to not carrying APN(AccessPointName in authentication request message, access point name) information, AAA cannot accurately select user to need the qos parameter used to license to 3GPP user from the authorization message of HLR/HSS, thus cause user can not use oneself signing qos parameter, reduce the experience of user.

Current ways of addressing this issue configures fixing QoS in focus in this locality or WLAN Access Network WLANAN, no matter user is signing in HLR/HSS is what, all adopt local configuration, this method greatly reduces the experience of user, and underaction.

Summary of the invention

Technical problem to be solved by this invention is 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(ServiceSetIdentifier of the WLAN carried in authentication request message, service set) or the MAC Address of focus Hotspot be mapped as corresponding APN, then AAA matches corresponding QoS CAMEL-Subscription-Information according to this APN from the authorization message of HLR/HSS, license to the 3GPP user roaming or be switched to wlan network to use, thus improve 3GPP user's roaming or the experience of the online after being switched to wlan network.

After step B, WLANAN receive WLAN authentication request message, 3GPP User Identity ID and WLAN address information are encapsulated in aaa authentication request message, send to 3GPPAAA server;

After step C, 3GPPAAA server receives aaa authentication request message, initiate authentication to HLR or HSS, certification is carried out to described 3GPP user; After certification is passed through, HLR or HSS transmits the CAMEL-Subscription-Information of 3GPP user to 3GPPAAA server, and the CAMEL-Subscription-Information of described 3GPP user comprises APN and the QoS information corresponding with APN;

Step D, 3GPPAAA server, according to the mapping relations of the preset WLAN address information in this locality and APN, obtains the APN that described 3GPP user is corresponding in 3GPP network;

From the CAMEL-Subscription-Information of described 3GPP user, 3GPPAAA server obtains the QoS CAMEL-Subscription-Information of 3GPP user according to APN, response aaa authentication request message, send aaa authentication acknowledge message to WLANAN, described aaa authentication acknowledge message comprises the QoS CAMEL-Subscription-Information of described 3GPP user;

Step e, after WLANAN receives aaa authentication acknowledge message, WLANAN responds WLAN authentication request message, sends WLAN authenticate-acknowledge message to 3GPP user equipment (UE), informs 3GPP user equipment (UE) authentication success, obtain correct QoS CAMEL-Subscription-Information;

Step F, after 3GPP user equipment (UE) receives WLAN authenticate-acknowledge message, judges authentication success, and by the direct accesses network of WLANAN.

In step D, described WLAN address information is the MAC Address of SSID or focus or the IP address of WLANAN or WLANAN mark.

Further, if IP address or the WLANAN mark of the SSID of WLAN or the MAC Address of focus or WLANAN cannot be obtained, then the APN of acquiescence is directly used.

The invention has the beneficial effects as follows: propose 3GPP user in a kind of wlan network and obtain the signing method of QoS.Described method is for 3GPP user's roaming or after being switched to wlan network, oneself signing qos parameter problem in 3GPPHLR/HSS cannot be obtained, adopt the APN of WLAN mapping address information 3GPP user, and then AAA obtains the QoS corresponding with 3GPP user APN by HLR or HSS and to contract parameter, and parameter of being contracted by APN and the QoS of this 3GPP user is to the WLANAN sending 3GPP user place to, thus effectively improve the experience that 3GPP user surfed the Net by WLAN.
