Abstract
The present invention relates to a method and arrangement for triggering a Random Access Channel (RACH) procedure for requesting uplink resources on a random access channel to a radio base station () scheduler based on a change in terminal () buffer status as compared to a Buffer Status Report BSR stored in said terminal. In a first method step, the status of the present terminal buffer content, i.e. terminal buffer data, is compared with the status of said stored buffer status report BSR. A second method step involves initiating a RACH procedure for indicating a service request to said base station scheduler upon detecting a change of buffer status at said comparison. The service request includes an indicator of the status change as a trigger for said scheduler to assign uplink resources to said terminal.
