Problems solved by technology

[0003] In the WiFi roaming scenario, after the mobile station switches from the current access point to the target access point, the mobile station needs to exchange keys with the target access point to obtain the key corresponding to the target access point. key, but the key exchange process will take a certain amount of time, resulting in high roaming delay

Embodiment Construction

[0030] refer to figure 1 , figure 1 is a schematic flowchart of a wireless roaming method provided by an embodiment of the present invention, figure 1 The roaming method shown is applicable to the current access point side, and includes the following steps. It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.

[0031] In S11, it is judged whether the mobile station is in a boundary state.

[0032] In some embodiments, when the current access point is connected to the mobile station, the current access point determines whether the mobile station is in a boundary state. The current access point refers to an access point connected to the station, that is, the station accesses the current access point. The current access point and the target access point have the same service set identifier (Service SetIdentifier, SSID). The station can switch between the current access point and the ...

Abstract

The invention provides a wireless roaming method, an access point device, and a mobile station. The wireless roaming method comprises steps: determining whether a key of a target access point corresponding to the mobile station is stored; if not, performing key exchange in representative of the mobile station and the target access point to obtain a key corresponding to the mobile station; and transmitting the key to the mobile station. According to the technical scheme, before the mobile station is connected with the target access point, a current access point obtains the key corresponding tothe mobile station from the target access point in representative of the mobile station; and therefore, after the mobile station is accessed to the target access point, the mobile station does not need to perform key exchange with the target access point so that the roaming delay caused by key exchange is reduced, the efficiency of wireless roaming is improved, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless roaming method, an access point device and a mobile station. Background technique [0002] In a wireless fidelity (Wireless Fidelity, WiFi) technology, a mobile station (station, STA) obtains network services by connecting to a wireless access point (Access Point, AP). However, the range covered by one access point is limited. And because of the fluidity of wireless Internet access, the mobile station may move out of the coverage of the access point it is currently connected to. By setting a new access point, the mobile station can connect to the new access point so as to maintain its original Internet access service. [0003] In the WiFi roaming scenario, after the mobile station switches from the current access point to the target access point, the mobile station needs to perform key exchange with the target access point to obtain the key corresponding to th...
