Abstract:
1. A method for a user equipment (UE), comprising: obtaining speed information of the UE in a mobile communication network, wherein the speed information is taken from a speed group comprising a physical speed, a physical speed mapped on a pre-defined speed group, and a virtual speed; setting a prohibit timer when speed information is sent to the network by the UE; detecting a trigger event, wherein the trigger event is taken from a triggering group comprising one of the UE changing from RRC_IDLE state to RRC_CONNECTED state and the UE detecting a background traffic mode in RRC_CONNECTED state, and wherein the background traffic mode is detected when detecting at least one of conditions comprising detecting a specific background application, activating of UE screen power saving, and detecting no interaction from users; and providing the speed information to the network by one or more predefined means when the prohibit timer expired and a sending condition is met, and wherein the sending condition comprises at least one of the trigger event is detected, and a speed exceeds a speed threshold.
