Abstract
A method and system for managing neighbor cell information are disclosed in the present invention. A user equipment is reselected into a current Universal Terrestrial Radio Access (UTRA) cell from a former resident cell belonging to other system, and finds out that the former resident cell is not in a neighbor cell list of the current UTRA cell and the user equipment itself supports a neighbor cell relation maintenance function, and/or after receiving an indication notified by a network side that the user equipment can report neighbor cell relation, the user equipment reports an air interface signaling message carrying cell information of the former resident cell to a Radio Network Controller (RNC); the RNC receives and decodes the air interface signaling message, acquires the cell information of the former resident cell, and updates inter-system neighbor cell information according to the cell information of the former resident cell.
