Methods of UE providing speed information to network

摘要

A method of user equipment (UE) providing speed information to network is provided. The method supports obtaining speed information of the UE, detecting a trigger event and providing the speed information to the network by one or more predefined means. The speed information is taken from the group consisting of a physical speed, a physical speed mapped on a pre-defined speed group, and a virtual speed. The virtual speed comprises a cell change count or a number cells that the UE has requested RRC connection during a certain period. The UE can send the speed information to an eNB via RRC connection establishment, RRC connection re-establishment, a new IE in RRC measure report or a new RRC message.

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.
