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.

Time check method and base station

A method for establishing a connection between a maintenance node and a base station includes the following steps: the base station switches over to a preset standby Operation & Maintenance (OM) channel when an main OM channel fails and sends to the maintenance node via the standby OM channel a notification that the base station has switched over to the standby OM channel; and the maintenance node establishes a connection with the base station over the standby OM channel by using a standby Internet Protocol (IP) address of the base station after receiving the notification. A base station is also provided.
