METHOD AND APPARATUS IN TELECOMMUNICATION SYSTEM Russian patent published in 2014 - IPC H04W74/08 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a method and an apparatus for triggering a random access channel (RACH) procedure for requesting uplink resources on a random access channel to a radio base station (600) scheduler based on a change in terminal (700) buffer status as compared to a buffer status report (BSR) stored in said terminal. In the first step of the method, 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. The second step of the method 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 step. The service request includes an indicator of the status change as a trigger for said scheduler to assign uplink resources to said terminal.

EFFECT: reduced system load.
