If the request of setting up of the tunnel of WLAN UE sends to WLAN (wireless local area network) and inserts the critical point, then this step can insert the critical point by WLAN (wireless local area network) and send the authenticated/authorized request message to 3GPP AAA Server.Carry user profile, tunnel information or WLAN user terminal state information in the message, such as user ID, W-APN parameter, adhere to/information such as released state, and comprise that WLAN (wireless local area network) inserts routing iinformations such as critical point sign.
Step 403~404:PDG, 3GPP AAA Server carry out the authentication and authorization process that service tunnel is set up with WLAN UE; And obtain the presentation information of current WLAN UE in the authentication of setting up in the tunnel, licensing process, comprise: the situation that inserts PS territory business, the situation in tunnel etc., for example: the W-APN of user ID and current activation thereof, the quantity in the tunnel of this W-APN correspondence, sign, corresponding service type, the qos parameter in this tunnel, the sign of this user place network etc.
Step 405:3GPP AAA Server sends success message to WLAN UE after authentication success is set up in the tunnel.
Step 406:3GPP AAA Server sends the current presentation information notice of user to PNA, comprise: the situation that inserts PS territory business, the situation in tunnel etc., for example: the sign of the qos parameter in the tunnel quantity of the W-APN of user ID, current activation, this W-APN correspondence, Tunnel Identifier, IP address of terminal, type of service, this tunnel and this user place network etc.
Step 407:PNA returns response to PDG after receiving presentation information notice, and the parameter that receives is converted into presents the content that system will present.
In addition, similar for the processing procedure of HLR, HSS and 3GPP AAA Server.
Embodiment 3:
Fig. 5 provides the process schematic diagram for the presentation information of the 3rd preferred embodiment of the present invention, referring to shown in Figure 5, in another preferred embodiment of the present invention, suppose that the presentation information monitor collecting unit belongs to 3GPP AAA Server, the process of wireless local network user accessing terminal to network is authentication, licensing process.Specifying information presents process and may further comprise the steps:
Step 501:WLAN UE sends the authenticated/authorized request by WLAN AN to 3GPP AAA Server;
Carry out authentication, licensing process between step 502:WLAN UE and the 3GPP AAA Server;
Step 503: carry out in authentication, the licensing process between WLAN UE and 3GPP AAA Server, 3GPP AAA Server obtains the presentation information of WLAN UE.
This step also can be carried out after finishing authentication, licensing process between WLAN UE and the 3GPP AAA Server;
The presentation information of obtaining includes but not limited to:
A) routing iinformation.
If present the current location that service system entity need be known the WLAN user terminal, the business that can provide to this WLAN user terminal with the place network, then 3GPP AAA Server with the routing iinformation of this user terminal correspondence as: the sign of visited network PLMN sign, WLAN access network etc. sends to and presents service system entity.
B) WLAN user terminal state information.
If present the state information that service system entity need be known the WLAN user terminal, then 3GPP AAA Server with the state information of described this WLAN user terminal correspondence as: adhere to (attach) state, separate information such as (detach) state and send to and present service system entity.
C) other presentation information.
Comprise user profile, type of service etc.
Above information can send wherein one according to different needs, also can send many to presenting system entity simultaneously.
Step 505:3GPP AAA Server sends the current presentation information notice of user to PNA, comprising: sign, WLAN UE state such as the information such as Attach state or Detach state of user ID, IP address of terminal, type of service, this user place network.
Step 506:PNA returns response to 3GPP AAA Server after receiving presentation information notice, and the parameter that receives is converted into presents the content that system will present.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
