A method and system for neighbor cell listcreation and verification in a telecommunications system is provided. Over a period of time measurements are performed on signals transmitted and received on measurement channels of cells neighboring the cell for which a neighbor cell list is being created. The results of the signal measurements are used to create an ordered list of the measurement channels on which the measurements were done. A neighbor cell list containing a desired number of cells is then created by placing a certain number of cells having the most interfered measurement channels in the neighbor cell list. The invention also presents a method and system for verifying an existing neighbor cell list. In the method and system measurements are performed on measurement channels of neighbor cells over a period of time. Periodically the measurement results are checked to determine if cells should be added to or deleted from the existing neighbor cell list.

[ What is claimed is:] [1.] In a cellular telecommunications system comprising a plurality of mobile stations, a first cell, and a plurality of neighbor cells, said neighbor cells each comprising at least one base station transmitting and receiving on one or more measurement channels, a method of creating a neighbor cell list for said first cell, said neighbor cell list used for transmission to mobile stations thereby enabling mobile stations to select candidate cells for handoff from said first cell, said method comprising the steps of:establishing a first neighbor cell list for said first cell;over the course of a plurality of calls by mobile stations within said first cell:measuring by those mobile stations in said first cell of signal strength on measurement channels of a group of neighbor cells including cells not in the first neighbor list; andsending the signal strength measurements by those mobile stations to the cellular telecommunications system; andprocessing by the cellular telecommunications system after the plurality of calls of the mobile station sent signal strength measurements, said step of processing including the steps of:creating an ordered list of said measurement channels, said list ordered according to said signal strength measurements obtained by the mobile stations over the course of the plurality of calls;determining one or more of the measurement channels from said ordered list having highest signal strength; andmodifying said first neighbor cell list for said first cell to include the neighbor cells associated with said determined one or more measurement channels having highest signal strength.
