Claim Text:
1. A method for triggering a transmission of Buffer Status Reporting (BSR) information from a User Equipment (UE) to a base station (BS) in a wireless telecommunication network, said UE comprising: a transmission buffer for storing data to be transmitted via a logical channel, said logical channel being provided with a priority level and a specific Prioritized Bit Rate (PBR) parameter indicating a resource level to allocate to the UE for transmitting the stored data, said BSR information representing an amount of data present in the transmission buffer of the UE and allowing said base station to schedule an amount of resource to allocate to the UE, the method comprising: triggering the transmission of Buffer Status Reporting information if new uplink data arrives in the UE transmission buffer and said new uplink data belongs to a logical channel for which a PBR is defined and for which no data already existed in the UE transmission buffer, wherein the transmission of the BSR information is triggered if said new uplink data belongs to a logical channel (respectively to a channel of a group of logical channels) having a non null PBR value and a priority level lower than that of a logical channel (respectively than that of a group of logical channels) for which the buffer already contains data to transmit, and for which sufficient resources have already been allocated by the base station to the UE.
