Server control plane connections recovery in a server-gateway architecture based telecommunication network

摘要

The present invention concerns a server control plane connections recovery method and a system for a server-gateway architecture based telecommunication network. Predetermined control data is buffered per traffic flow in the server and the buffered control data of a traffic flow is transmitted to the gateway associated with said traffic flow if there is change in said data. The transmitted control data is stored in said gateway. The server is restarted if it malfunctions and an indication about the server restart is transmitted to one or more gateways. The stored control data is transmitted back to the server from one or more gateways in response to a received server restart indication. The server control plane connections are restored to state before restart by utilizing the control data received from the gateways.
