METHOD, NETWORK ELEMENT DEVICE AND NETWORK SYSTEM FOR ESTABLISHING THE CONNECTION BETWEEN MAINTENANCE STATION AND BASE STATION

摘要

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 includes: a switchover unit, adapted to switch over to a preset standby OM channel when an main OM channel fails; a notification sending unit, adapted to send to a maintenance node via the standby OM channel a notification that the base station has switched over to the standby OM channel; and a connection establishing unit, adapted to establish a connection between the base station and the maintenance node over the standby OM channel by using a standby IP address after the switchover unit switches over to the preset standby OM channel.
