Triggering a handover process based on the activity of a connection

摘要

Embodiments herein relates to a radio network node (12) for controlling a handover process of a user equipment (10) from a first cell (11) to a second cell (14). The user equipment (10) is served in the first cell configured to be controlled by the radio network node. The radio network node comprises an operating circuit configured to operate according to a handover process, which handover process is triggered by a first trigger parameter when a connection to the user equipment is active, and by a second trigger parameter when the connection to the user equipment is inactive.

1. A method in a radio network node comprising:
controlling, by the radio network node, a handover process of a user equipment from a first cell to a second cell, which user equipment is served in the first cell controlled by the radio network node, wherein a first handover process is triggered by a first trigger parameter when a connection to the user equipment is active, and a second handover process is triggered by a second trigger parameter when the connection to the user equipment is inactive; receiving periodically a measurement report from the user equipment, which measurement report indicates signal strengths of the first cell and of the second cell; and initiating the first handover process when a difference of the signal strengths in the measurement report is above a first threshold value and when the connection to the user equipment is active, and initiating the second handover process when the difference of the signal strengths is above a second threshold value and when the connection to the user equipment is inactive, which first threshold value is lower than the second threshold value and wherein the first threshold value is associated with the first trigger parameter and the second threshold value is associated with the second trigger parameter.
