The invention relates to a method, an arrangement and a system for rerouting the useful data flow in a packet network within the frame of a service, whereby the resources for executing said service are provided in the area for action of a switching center. According to said invention, a packet converter is provided in the area for action of said switching center and, within the frame of said service, the useful data flow is carried through the packet converter. The adaptations, which are necessary for rerouting said useful data flow, are executed in said packet converter. The present invention has the advantage that only the switching center, which is responsible for the resource allocation, is concerned when the useful data flow is rerouted. Inter-exchange signaling with other switching centers is thus substantially reduced. Another advantage is that rerouting of said useful data flow does not depend on the performance characteristics of the other switching centers, which are involved, for example, in the setting-up of a call. |
