A telecommunications network is provided comprising a plurality of interconnected communications nodes, each of the communications nodes being connected to at least one of the other communications nodes in the telecommunications network via a communications channel. The communications nodes are arranged to communicate user data to and/or from the other communications nodes to which the communications nodes are connected in accordance with current operating communications parameters. Each of the communications nodes is adapted to communicate status report data to a policy control server, the status report data including an indication of the current operating communications parameters of the communications node and/or the communications channel via which the communications node. The policy control server is operable to determine, from the status report data, a current communications capability of the communications nodes, to identify a change in the operating parameters of one or more of the communications nodes or the communications channels, which could improve the performance of the telecommunications network and to communicate control data to the one or more communications nodes, the change control data indicating the identified change in the operating parameters. The policy control server can provide an improved allocation of network resources and network routing, because the policy control server is provided with a more global view of the telecommunications network, in one mode of operation the policy control server can re-configure the communications nodes and communications channels as a result of a failure of one or more of the nodes or channels. |
