IFLS can be turned off in a cell by removing all load-sharing neighbors of a cell, that is, by setting the loadSharingCandidate attribute to FALSE in all neighbor-cell relations for that cell. The amount of resource excluded from load-sharing use is specified by the cell parameter loadSharingMargin as a percentage of pwrAdm.
The performance of IFLS can be monitored through the following three counters, refer to Radio Network KPIfor more:
■pmTotNoRrcConnectReq gives the total number of RRC connection requests in a cell
■pmNoLoadSharingRrcConn gives the number of RRC redirections performed for load-sharing reasons in a cell
■pmNoOfReturningRrcConn gives the number of calls that has returned to the original frequency after an RRC-redirection
Note: This counter is stepped in the cell to which the UE returns. It is possible for the UE to return to the same frequency but not to the original cell.
