摘要

The invention relates to a method for operating a switching node (145) of a communications network, wherein the communications network comprises a layered architectural environment in which a split is provided between the user plane and the control plane (110) and a non-layered architectural environment in which there is no such split (105). The switching node (145) provides operation modes for the processing of communications services both within the layered and the non-layered architectural environment. The method comprises the steps of receiving a communication service request, determining according to at least one predetermined rule an operation mode for processing of the requested communication service and processing the requested communications service in accordance with the determined operation mode of the switching node (145). The invention relates further to a corresponding network node, communiations system and computer program.
