A system for solving a technical problem in a network architecture with at least one service operator network and a plurality of in-house networks supported by the at least one service operator network, includes a computing device adapted to receive in-house network parameters and to determine, based on the received in-house network parameters, a coordination strategy involving the reconfiguration of a number of involved in-house networks being supported by a number of involved service operator servers. The computing device is adapted to inform the number of involved operator servers of the coordination strategy. A service operator server is adapted to reconfigure an in-house network according to the coordination strategy to solve the technical problem.
