Connection establishing method, terminal and access point

Abstract

The invention discloses a connection establishing method, a terminal and an access point (AP). The method comprises the following steps of: sending a first authentication message comprising a user identifier to the AP; receiving a second authentication message which is sent by the AP according to the user identifier and comprises an extensible authentication protocol (EAP) method request message and a site value ANonce of the AP; generating a first pairwise transient key (PTK) according to the ANonce, an SNonce and acquired first minimum shift keying (MSK); sending a third authentication message to the AP, wherein the third authentication message comprises an EAP method response message, the SNonce and first minimal inhibitory concentration (MIC) generated according to the first PTK; receiving a fourth authentication message which is sent by the AP when the first MIC is checked to be correct according to a second PTK, wherein the fourth authentication message comprises an EAP success message, configuration information configured by the AP to the terminal, and second MIC; and checking the second MIC according to the first PTK. By the method, the terminal and the AP of the embodiment of the invention, the interaction number of empty messages can be reduced, and the connection establishment time is shortened, so that electric consumption of the terminal can be reduced, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a connection establishment method, terminal and access point in the communication field. Background technique [0002] When a Wireless Fidelity (Wireless Fidelity, "WiFi" for short) terminal (Station, "STA" for short) securely connects to a WiFi access point (Access Point, "AP" for short), it needs to The standard 802.11 protocol completes the prescribed scanning, open authentication, association, 802.1x authentication (that is, Extensible Authentication Protocol (Extensible Authentication Protocol, referred to as "EAP") authentication), four-step handshake and other processes. Protocol, referred to as "IP") address allocation process. [0003] Specifically, generally, the STA can send a probe request frame to the AP, and according to the probe response returned by the AP, discover the AP and query the attributes and capabilities of the AP. Before this, the STA can also listen...

Problems solved by technology

[0008] However, since the STA is entering the WiFi network for the first time, the WiFi network does not have the context information of the STA before, so the STA needs to complete the authentication, association, four-step handshake, IP address allocation and other processes with the AP and AS.

During the initial connection establishment process, there are many air interface message interactions between the STA and the AP, which takes a long time, which will not only increase the power consumption of the terminal, but also seriously affect the user experience.
