Claims

1. In a cellular communication system, a method of selecting a target cell for a handoff, such method including the steps of:
A) identifying reported RSSI values of appropriate, opposing BTSs;
B) calculating a power budget value based upon reported RSSI values for each of the identified opposing BTSs; and,
C) selecting the appropriate opposing BTS providing the largest relative magnitude power budget value as the handoff target

2. The method as in claim 1 wherein the step of selecting the opposing BTS providing the largest magnitude power budget value as the handoff target further includes the step of deferring handoff . pon occasion that the reported RSSI value of the serving BTS exceeds the selected opposing BTS.

3. The method as in claim 1 wherein the step of identifying reported RSSI values of appropriate, opposing cells further includes the step of including all opposing BTSs are appropriate opposing BTSs.

4. The method as in claim 1 wherein the step of identifying reported RSSI values of appropriate, opposing ceils further includes the step of including only those opposing BTSs proximate a reporting co-sited BTS.

5. The method as in claim 1 wherein the step of identifying reported RSSI values of appropriate, opposing cells further includes the step of including only those opposing BTSs proximate a proportional, co-sited BTS.

6. In a cellular communication system, an apparatus for selecting a target cell for a timing advance handoff, such method including the steps of:
A) means for identifying reported RSSI values of appropriate, opposing BTSs;
B) means for calculating a power budget value based upon reported RSSI values for each of the identified opposing BTSs; and,
C) means for selecting the opposing BTS providing the largest relative magnitude power budget value as the handoff target

7. The apparatus in claim 7 wherein the means for selecting the opposing BTS providing the largest magnitude power budget value as the handoff target further includes means for deferring handoff upon occasion that the reported RSSI value of the serving BTS exceeds the selected opposing BTS.

8. The apparatus in claim 7 wherein the means for identifying reported RSSI values of appropriate, opposing cells further includes means for including all opposing BTSs are appropriate opposing BTSs.

9. The apparatus as in claim 7 wherein the means for identifying reported RSSI values of appropriate, opposing cells further includes means for including only those opposing BTSs proximate a reporting co-sited BTS.

10. The apparatus as in claim 7 wherein the means for identifying reported RSSI values of appropriate, opposing ceils further includes means for including only those opposing BTSs proximate a proportional, co-sited BTS.
