NETWORK NODE AND METHOD THEREIN FOR HANDOVER IN WIRELESS COMMUNICATION NETWORK

摘要

A network node (121) and method therein for assisting a communication device (110) to perform handover from a serving cell (120) to a target cell (130) in a communication network (100) are disclosed. The network node (121) is configured to obtain a first round trip time between the network node (121) and a server (140) and obtain a second round trip time between a target node (131) in the target cell (130) and the server (140). The network node (121) is further configured to instruct the communication device (110) to perform handover from the serving cell (120) to the target cell (130) based on at least the first round trip time and the second round trip time.
