1. A method for traffic and resource control in a wireless communication device with a plurality of operation modes, the method comprising the steps of:

  • assembling data units of at least one incoming data stream into an output data stream, the data units destined for at least one destination node and a service level requirement attached to each of the at least one destination node;

    selecting a first set of radio transmission resources for the output data stream, wherein the first set of radio transmission resources belongs to radio transmission resources available in the wireless communication device;

    searching for a path that leads from the wireless communication device to one of the at least one destination node and fulfills the service level requirement corresponding to that destination node when one leg of the path is implemented by the first set of radio transmission resources, wherein the searching step is performed with respect to each of the at least one destination node;

    scheduling transmission of the output data stream when the path is found for each of the at least one destination node in the searching step, wherein the transmission is scheduled to occur through the first set of radio transmission resources; and

    , controlling the operation modes of the wireless communication device so that (1) an operation mode corresponding to the first set of radio transmission resources is active when the transmission is scheduled to occur and that (2) the wireless communication device is with respect to its other operation modes in a state where the service level requirement of each destination node is maintained during the transmission.
