Description

WLAN startup optimization method and device

technical field

The present disclosure relates to the technical field of WLAN, and in particular to a method and device for WLAN start-up optimization.

Background technique

WiFi is one of the wireless broadband technologies. It has developed rapidly in recent years. With the popularization of WiFi, people's daily life and work are increasingly inseparable from WiFi. At the same time, the low price and high transmission rate of WiFi make it obtain rapid development and application. At present, PMK (Pairwise MasterKey, Pairwise Master Key) is required for WiFi connection in the operating system. When each WLAN is started, we need to generate and cache PMKs for all previously connected WiFi access points. It takes a lot of time to generate PMKs using, for example, a hash encryption algorithm. Some mobile phone processors calculate a WiFi at full speed. The PMK time of the access point will be above 80ms, and if there are a large number of tasks running, it may be above 120ms. Statistics on mobile phone users show that some mobile phones store more than 300 WiFi access point information at most. In this case, it may take more than 36000ms to generate a PMK each time WiFi is turned on, that is, more than 36S, which wastes a lot of user time.
