Embodiment Construction

[0015] Referring to FIG. 1 , it is an implementation environment diagram of the method for determining a pre-shared key in the present invention. In this embodiment, the wireless communication system includes a first access point 100 , a plurality of second access points 200 and a mobile station (mobile station) 300 . Wherein, the first access point 100 includes a virtual mobile station 120 , and the virtual mobile station 120 is a fake mobile station in the mobile station 100 . The mobile station 300 can be a mobile electronic device such as a mobile computer, a personal digital assistant (PDA), or the like.

[0016] The mobile station 300 communicates with the first access point 100, and both support the same PSK (Pre-sharedKey, PSK), but the mobile station 300 needs to roam from the first access point 100 to one of the multiple second access points 200 . Multiple second access points 200 are within the communication coverage of the first access point 100 . The first acce...

Abstract

The invention includes faking module, and virtual mobile station. The faking module is in use for faking virtual mobile station. Virtual mobile station includes authentication sub module, connection sub module, and handshaking sub module. The authentication sub module is in use for carrying out authentication for multiple other access points. The connection sub module is in use for connecting multiple other access points. The handshaking sub module is in use for carrying out four times of handshaking to multiple other access points and determining whether multiple other access points and the access point support same pre shared cipher key. The access point makes mobile station, which communicates with the access point, know whether other access points within the range of the access point and the access point support same pre shared cipher key in advance. The invention same roam time of mobile station.

Description

【Technical field】 [0001] The invention relates to the field of wireless communication, in particular to an access point and a method for determining a pre-shared key. 【Background technique】 [0002] In a wireless communication system, if a mobile station adopts a pre-shared key (Pre-shared Key, PSK) connection method, the access point communicating with it must support the same PSK connection method. The so-called same PSK means that both adopt the PSK mode, and the keys (Key) of the two PSKs are the same. Therefore, if a mobile station using PSK needs to roam, it must find an access point that supports the same PSK. [0003] In the traditional method, if the mobile station wants to roam, it first disconnects from the old access point (that is, the access point communicating with the mobile station), and then re-scans for a new access point. The mobile station performs a detection connection to the scanned access point, and if it finds that the access point supports a diff...
