MOBILITY ROBUSTNESS OPTIMIZATION IN A CELLULAR NETWORK

摘要

The present invention relates to a method in a node of a cellular network for supporting mobility, to a method in a user equipment for supporting mobility to in the cellular network, and to corresponding devices. According to one aspect, a method for supporting mobility in a cellular network is provided. The method runs in a node for the cellular network. According to the method, the node receives from a user equipment, an information of a radio link failure of a radio link between the user equipment and the cellular network and the node receives information related to a mobility of the user equipment. Based on the received information, the node adjusts at least one mobility parameter to increase robustness of mobility. The present invention improves robustness of mobility functions in a cellular network.
