Abstract
In the present invention, a pilot packet is created as a response to an indication that a data stream is to take place within a short while. The small pilot packet shall be transported from the sender to the same receiver as the receiver of the subsequent data stream a short time before the first data packet is sent to the receiver. The pilot packet will trig the allocation of transmission resources, typically radio links, along its signalling path. When the data packets are transported along the same path a short time later, the transmission resources are already allocated according to conventional dynamic allocation schemes.

20. Method of transferring data packets in a communications system using a scheme for dynamic allocation of transmission resources, comprising the steps of:
-
preparing, in a data packet handling device, data packets to be transferred;
transferring said prepared data packets over at least one link using dynamic allocation;
detecting initiation of a procedure in said data packet handling device leading to subsequent creation of data for said data packets to be transferred;
creating, as a response of a detected initiation, a pilot packet; and
transferring said pilot packet, prior to completion of said preparing step for a first data packet and thereby prior to said transferring of said prepared data packets, over said at least one link, whereby transmission resources of said at least one link are allocated according to said scheme. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. Device in a communications system having capability of transferring data packets using a scheme for dynamic allocation of transmission resources, comprising:
-
means for preparing data packets to be transferred;
transferring means, connected to said means for preparing data, said transferring means being arranged for transferring said prepared data packets over at least one link using dynamic allocation;
detecting means for detecting initiation of a procedure in said means for preparing data packets; and
means for creating a pilot packet as a response of a detected initiation, connected to said detecting means;
whereby said transferring means is further arranged for transferring said pilot packet, prior to completion of said preparing step for a first data packet and thereby prior to said transferring of said prepared data packets, over said at least one link, whereby transmission resources of said at least one link are allocated according to said scheme. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
