Access processing, access method and device of WLAN (Wireless Local Area Network)

[0049] image 3 It is a flowchart of a WLAN access processing method according to Embodiment 1 of the present invention. Such as image 3 As shown, the method includes:

[0050] Step S302, the ANDSF entity receives the location information reported by the UE;

[0051] In step S304, the ANDSF entity delivers WLAN access information to the UE according to the received location information, wherein the WLAN access information is used to indicate the UE's access policy to the WLAN network.

[0052] Through the above processing steps, since the ANDSF entity sends the indication information for indicating the UE's access policy to the WLAN network to the UE, the UE can select an appropriate WLAN access according to the above access policy. Therefore, the problem that the ANDSF entity only It simply distributes the discovered WLAN information (such as the WLAN list), and users cannot choose the appropriate WLAN access and other technical issues according to their actual needs, which

[0068] This embodiment corresponds to Embodiment 1, and describes WLAN access on the UE side. Figure 5 It is a flowchart of a WLAN access method according to Embodiment 2 of the present invention. Such as Figure 5 As shown, the method includes:

[0069] Step S502, the UE receives WLAN access information from the ANDSF entity, wherein the WLAN access information is used to indicate the UE's access strategy to the WLAN network;

[0070] Step S504, the UE accesses the WLAN indicated by the above access policy.

[0071] In this embodiment, the access strategy includes at least one of the following information: WLAN geographic location information; location name information of the administrative area where the WLAN is located; WLAN priority information; authentication mode information supported by the WLAN operator; Partner project 3GPP associated cell information.

[0072] In this embodiment, a WLAN access device is also provided, which is located in the UE, and the device is u

[0077] This embodiment provides a method for an ANDSF network element to issue a WLAN location according to the location information reported by the UE.

[0078] In this embodiment, the UE reports its location, and the ANDSF provides WLAN information to the UE. Its main design ideas are:

[0079] ANDSF provides WLAN geographic location information (including longitude, latitude, altitude, etc.) to UE;

[0080] ANDSF provides WLAN city information to UE;

[0081] ANDSF provides WLAN priority to UE;

[0082] ANDSF provides UE with WLAN operator support authentication mode information;

[0083] The ANDSF provides the UE with the information of the 3GPP associated cell to which the WLAN belongs.

[0084] The ANDSF management object tree adds WLAN geographic location information (including longitude, latitude, altitude, etc.), city information, priority, operator support authentication methods, and 3GPP associated cell information. For details, please refer to Figure 7 , the sp
