HANDOVER IMPROVEMENT FOR HIGH SPEED USER EQUIPMENT IN LTE

摘要

Methods and apparatus are disclosed for handing over of a high-speed mobile terminal or user equipment (106) from a source network node (104) to a target network node (108). Reliable methods for measuring the speed of a moving user equipment (106) are disclosed. Parameters used in a handover procedure are also adjusted in accordance with the speed of the user equipment (106). For handing over a high-speed user equipment (106), the present application discloses that the source network node (104) can coordinate with the target network node (108) and other candidate network nodes (110) in transmitting a handover command to prevent handover failures.
