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. |
