ACCESS BSC - PMR ImplementationBSC OVERLOAD PROTECTION:

0.4 Signalling link load

80% Ater Utilization (average)

80% TRX Utilization (average)

80% CPU Load (average)

90% Gb link load (average)

BTS REHOMING CONSIDERATION: Ater utilization of target BSC < 80%

Paging load of target BSC < 150000 pages (assuming 1

LAC per BSC) Signaling link load of target BSC < 0.4

CPU load of target BSC < 80%

Gb link load of target BSC < 90%

Gb link license (GPRS/EDGE) must be updated

VLR of target homing MSC < 85%
