Method and apparatus for frequency planning in a cellular communications system using modified neighbour lists
First Claim
1. A method of determining frequency planning measurement data in a cellular communications system using different neighbor lists allocated to different mobile stations, comprising the steps of:
- allocating different test frequencies in the different neighbor lists for substantially each call conducted by a base station of the cellular communication system;
wherein the different neighbor lists are allocated to different mobile stations on a per call basis to cover, over a plurality of calls, substantially all the test frequencies for the cell served by the base station; and
repeating, on a cyclical basis comprising repeated calls, the allocation of the different neighbor lists on a per call basis covering substantially all the test frequencies;
wherein the different neighbor list is allocated for each of a predetermined number of calls conducted by the base station of the cellular communications system, compared to the predetermined number of directly preceding calls.

Abstract
A method, and apparatus for, determining frequency planning measurement data in a cellular communications system (1), comprising: allocating neighbor lists (208, 210, 212) to provide measurement data for frequency planning; wherein the neighbor lists (208, 210, 212) are allocated on a per call basis. Thus different neighbor lists (208, 210, 212) may be allocated by the same base station (28) to different mobile stations (44, 46, 48) for respective calls (204) that overlap in time. A different neighbor list (208, 210, 212) may be allocated for substantially each call (204) conducted by a base station (28) of the cellular communication system (1), compared to respective directly preceding calls or may be allocated for substantially each of a predetermined number of calls conducted by a base station (28) of the cellular communications system (1), compared to the predetermined number of directly preceding calls. At least substantially all test frequencies (206) for the cell (16) served by the base station (28) may thereby be covered over a plurality of calls (204).
