METHOD AND APPARATUS FOR RELOCATING AND RESTORING CONNECTIONS THROUGH FAILED SERVING GATEWAY AND TRAFFIC OFFLOADING

Abstract

PROBLEM TO BE SOLVED: To solve the problem that when a signaling load upon detection of an SGW restart is not appropriately managed by the PGW MME and S4-SGSN it may lead to congestion overload and/or instability in the public land mobile network where the SGW has active PDN connections.

SOLUTION: This invention relates to a method for controlling connections which pass through at least one serving gateway of a radio communication network. The method includes the steps of: receiving a first message in a serving gateway support node from an operator requesting that at least some connections to be offloaded from a first serving gateway; and in response to the first message relocating at least some of the connections from the first serving gateway to a second serving gateway by the serving gateway support node.
