Method for base stations under same routing area to share tunnel resources

Abstract

The invention provides a method for base stations under the same routing area to share tunnel resources, which comprises the following steps that: a terminal is switched to a new base station under a new routing area from an original base station under an original routing area; a tunnel is established between the original base station and the new base station and is subject to link maintenance through a heartbeat message; simultaneously the original base station informs the new base station of a base station list under the original base station and synchronously updates the base station list; the base stations under the same routing area mutually inform of the tunnel load conditions of the base stations; when the load of the original base station is extremely-heavy, the original base station analyzes the tunnel load conditions of other base stations under the original routing area and shares partial load per se to the base stations with low current load; and when the new base station does not receive the heartbeat message of the original base station for a long time, the new base station transmits messages to other base stations under the original routing area and requests the other base stations to take over the tunnel of the original base station. The method can ensure that tunnel loads of various base stations are balanced and the off-line rate of users can be greatly reduced by the timely transfer of the tunnel resources even if a certain base station is abnormal.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for sharing tunnel resources by base stations in the same routing area. Background technique [0002] In a wireless communication system, when a terminal undergoes inter-cell handover, the base station will establish a tunnel for it to achieve correct packet forwarding. With this mechanism, the tunnels are mostly built on the base stations near the cell border, and the service quality provided to users will be reduced due to the heavy load of the cell border base stations; and when these base stations are abnormal, they will not be able to provide users with normal services. Even cause the user to drop the line. [0003] Since there are correspondingly fewer base station tunnels inside the cell, the load is also small. Therefore, it may be considered to share tunnel resources between base stations to share loads. Contents of the invention [0004] In order to s...
