Problems solved by technology

In other words, when the UE accesses the 3GPP core network successively from 3GPP and WLAN, even if the 3GPP access network and the WLAN access network are the same operator and share the same subscription data, the authentication process needs to go through two set, which will bring a long delay to the connection establishment

Embodiment 1

[0060] The wireless local area network access authentication method provided by the embodiment of the present invention, such as figure 2 As shown, the method steps include:

[0061] S201. The access point device acquires the user identity of the user equipment through the wireless local area network WLAN.

[0062] S202. The access point device finds, according to the user identifier, a key used for air interface encryption between the user equipment and the 3GPP network.

[0063] Before this step, the method may further include: the base station of the 3GPP network receives, through the 3GPP network, the first message including the user identity sent by the user equipment, and extracts and saves the user identity.

[0064] The base station obtains the key, and saves the key and the corresponding relationship between the key and the user identity.

[0065] Further, "the base station obtains the key" may include:

[0066] The base station receives the initial context establ...

Embodiment 2

[0091] The wireless local area network access authentication method provided by the embodiment of the present invention takes the integration scenario of the 3GPP access network and the WLAN access network as an example, and the user identity of the UE is described by taking the MAC address as an example. In addition, in this embodiment, the base station (eNodeB) of 3GPP and the access point device (Wifi) of WLAN are physically the same entity that can communicate with each other, but are relatively independent in function.

[0092] like image 3 As shown, this embodiment is described by taking the steps of the UE first accessing the 3GPP core network from the 3GPP and successfully authenticated and then accessing the 3GPP core network from the WLAN as an example.

[0093] S301. The UE accesses the 3GPP network, and sends an attach request message to the MME.

[0094] S302, the UE completes authentication and encryption with 3GPP through the MME.

[0095] Exemplarily, in thi...

Embodiment 3

[0110] The wireless local area network access authentication method provided by the embodiment of the present invention is basically similar to the second embodiment, except that the 3GPP base station (eNodeB) and the WLAN access point device (Wifi) are in different physical entities that can communicate with each other.

[0111] like Figure 4 As shown, in each step of this embodiment, the initial part is the same as step S301 to step S305 of the above embodiment, and will not be repeated here.

[0112] Later, including:

[0113] S306', the access point device sends a key query message including the MAC address to the base station.

[0114] S306 "The base station sends a key response message including the key corresponding to the MAC address to the access point device, and the access point device extracts the key from the key response message.

[0115] The steps after the access point device extracts the shown key are also the same as step S307 in the above embodiment, and ...

Abstract

Embodiments of the present invention provide a wireless local area network access authentication method, device, and system, which relate to the communication field, and can Realize quick authentication when UE accesses 3GPP core network successively from 3GPP and WLAN. The wireless local area network access authentication method includes: an access point device obtains a user identification of a user equipment through a wireless local area network WLAN; An air interface encrypted key; the access point device sends an authentication success message carrying the key or a derived key of the key to the user equipment through the WLAN, to indicate that the user equipment is allowed to use The key or the derived key accesses the WLAN. The embodiment of the invention is used for wireless local area network access.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless local area network access authentication method, device and system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) access network and the wireless local area network (Wireless Wireless Local Area Network, WLAN) access network integration—that is, the functional integration of the 3GPP access network and the WLAN access network are independent but physically integrated, the authentication process for the existing user equipment (User Equipment, referred to as UE) to access from the 3GPP network and the WLAN network successively is as follows: figure 1 As shown, generally include: [0003] S101. The UE accesses the 3GPP network, and sends an Attach Request to a Mobility Management Entity (MME for short). [0004] S102, 3GPP network authentication and establishment of a NAS (Network Access Server, network access server) security process—tha...
