The present invention relates to a communication system supporting communication of packet data. It comprises a core network, which comprises a number of packet data support nodes and a number of gateway nodes for communication with external packet data networks, and a number of radio networks. Each radio network comprises radio network control means. Each of at least some of the packet data support nodes comprises a separate functional server node. A number of said functional server nodes are provided to, in common, control at least a number of radio network control means such that said functional server nodes form a pool of functional server nodes, in which each functional server node is able to control any radio network control means. |
