摘要

A positioning cycle adjustment method comprising: obtaining, by a mobile device, a group of environment record information in a current environment; determining, by the mobile device, a location change rate value of the mobile device based on obtained N groups of environment record information, where N is greater than or equal to 2; and then adjusting a positioning cycle of the mobile device based on the determined location change rate value.

說明書

Specifically, the Manhattan distance is also referred to as a city block distance. A Manhattan distance between the location points of the mobile device that are corresponding to the first environment record information and the second environment record information is calculated as:

d 12 = k = 1 M ? ? ? RSS 1 ? k - RSS 2 ? k ? .

Specifically, a Chebyshev distance between the location points of the mobile device that are corresponding to the first environment record information and the second environment record information is calculated as:

d 12 = lim i ? ( k = 1
