RL3188: CELL_PAGING_OVERLOAD
This measurement provides the ratio of the number of times of PCH overload due to heavy CS and PS services to delivered paging messages for CS and PS services. The BTS stores the paging messages from the BSC and the PCU on the downlink CCCH (PCH) to different receiving buffer queues. When the length of the receiving buffer queue exceeds the threshold, the downlink CCCH is considered to be overloaded. When the downlink CCCH in the cell is overloaded, the BTS reports the overload information to the BSC and identifies the reason for the overload. If the overload is due to heavy CS services, the BTS reports a CCCH LOAD IND message to the BSC. If the overload is due to heavy PS services, the BTS reports a PACKET CCCH LOAD IND message to the BSC and then the BSC forwards the message to the PCU.
%.
None.
OVERLOAD rate of paging =
([MSG CCCH LOAD IND (PCH) Messages Sent on Abis Interface] + [PACKET CCCH LOAD IND Messages Sent on Abis Interface]) x {100}
/
([Delivered Paging Messages for CS Service] + [Delivered Paging Messages for PS Service])
