Claim Text:
1. A mobility management method of a wireless communication device capable of communication with a wireless communication network according to at least a first radio access technology, the method comprising, when the wireless communication device performs a cell switch from a first cell to a second cell: receiving a first signal related to the first cell; calculating a size of the first cell, based on the first signal, as an estimated distance from the wireless communication device to a base station of the first cell; receiving a second signal related to the second cell; calculating a size of the second cell, based on the second signal, as an estimated distance from the wireless communication device to a base station of the second cell; scaling at least one mobility parameter based on the determined sizes of the first and second cells, wherein the at least one mobility parameter is scaled by a ratio or quantized ratio between the determined sizes of the first and second cells; performing mobility management in the second cell based on the at least one scaled mobility parameter.
