1. A method comprising:
receiving information from an access node in a mobile network providing access for a terminal, said information being indicative of that said terminal is allowed to request establishing a data rate boost with respect to an uplink flow of said terminal;
deciding to request establishment of said data rate boost; and
transmitting, to said access node, a request for establishing said data rate boost, wherein a packet data unit session corresponding to said uplink flow is not modified,
wherein said request is transmitted as a valid code point in a buffer status of a logical channel group containing a logical channel carrying said uplink flow for which said data rate boost is requested,
wherein said data rate is activated by relocating said uplink flow to a dedicated radio bearer providing higher data rate than a current dedicated radio bearer,
wherein said request is indicative of a data rate boost timer upon an expiry of which said data rate boost is to be de-activated, wherein the timer for how long the data rate boost is assumed is part of a configuration of the terminal on a quality of service flow level, and when a data boost occurs for a quality of service flow, the terminal is configured to indicate the data rate boost and signals it to access node,
wherein signaling from the terminal to the access node comprises a special code point in a buffer status of the logical channel group containing the logical channel carrying the quality of service flow, wherein the special code point is made invalid/forbidden when the terminal is configured to signal a data rate boost and a data rate boost does not occur.
