Abstract

A method, and apparatus for, determining frequency planning measurement data in a cellular communications system (1), comprising: allocating neighbour lists (208, 210, 212) to provide measurement data for frequency planning; wherein the neighbour lists (208, 210, 212) are allocated on a per call basis. Thus different neighbour 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 neighbour 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).

Claims

1. A method of determining frequency planning measurement data in a cellular communications system, comprising:

allocating neighbor lists to provide measurement data for frequency planning;

wherein the neighbor lists are allocated on a per call basis.

2. A method according to claim 1, wherein different neighbor lists are allocated by the same base station to different mobile stations for respective calls that overlap in time.

3. A method according to claim 1, wherein a different neighbor list is allocated for each call conducted by a base station of the cellular communication system, compared to respective directly preceding calls.

4. A method according to claim 1, wherein a different neighbour list (208, 210, 212) is allocated for 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.

5. A method according to claims 1, wherein the neighbor lists are allocated on a per call basis such as to cover, over a plurality of calls, substantially all test frequencies for the cell served by the base station.

6. A method according to claim 5, further comprising repeating, on a cyclical basis comprising repeated pluralities of calls, the neighbor lists allocated on a per call basis covering substantially all the test frequencies.

9. An apparatus for determining frequency planning measurement data in a cellular communications system, comprising:

means for allocating neighbor lists to provide measurement data for frequency planning;

wherein the means for allocating neighbor lists are adapted to allocate the neighbor lists on a per call basis.

10. An apparatus according to claim 9, wherein the means for allocating neighbor lists are adapted to allocate different neighbor lists from the same base station to different mobile stations for respective calls that overlap in time.

11. An apparatus according to claim 9, wherein the means for allocating neighbor lists are adapted to allocate a different neighbor list for each call conducted by a base station of the cellular communication system, compared to respective directly preceding calls.

12. An apparatus according to claim 9, wherein the means for allocating neighbour lists are adapted to allocate a different neighbour list (208, 210, 212) for 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.

13. An apparatus according to claim 9, wherein the means for allocating neighbor lists are adapted to allocate the neighbor on a per call basis such as to cover, over a plurality of calls, at least substantially all test frequencies for the cell served by the base station.

14. An apparatus according to claim 13, wherein the means for allocating neighbor lists are adapted to repeat, on a cyclical basis comprising repeated pluralities of calls, the neighbor lists allocated on a per call basis covering substantially all the test frequencies.
