TIME CHECK METHOD AND BASE STATION

摘要

A time check method and a base station are provided. The base station receives an authentication interaction message sent by an authentication interaction device; extracts time information in the authentication interaction message; and uses the time information to check local time. Before an Internet Key Exchange (IKE) connection is set up between the base station and a security gateway, relatively accurate time is obtained from an external authentication interaction device and is used for aligning the local time. Therefore, the cost of installing a clock component and a battery is saved, the time on the base station is trustworthy, and the security gateway is authenticated securely.
