1 3 Resource Access MeasurementResource Access Measurement registers information on all common control channels (CCCH) of the base station controller. The recorded items of data comprise the number of messages sent to the Abis interface. The messages are sorted according to message type, average load on control channels, and the number of traffic channel seizures for mobile originating (MOC) and terminating calls (MTC). Signalling charts are drawn with the accuracy of message interface.

Counter ID: 003008 Network element name: AVE PCH LOAD ON CCCH

Version: 3.0 NetAct name: AVE_PCH_LOAD

Description: When divided by the value of counter 003009, this counter tells the Average PCH load on a CCCH. It indicates the remaining space for Paging Commands associated with this CCCH timeslot, given as the number of additional Paging Commands that it is possible to store. The smaller the value, the greater the load on the PCH.

This counter is updated along with counter 003009.

Updated: Cumulatively during the measurement period every time when the latest value of the PCH load is received in a CCCH_LOAD_INDICATION message from the BTS.

Updated: When the value of the RACH load received in a CCCH_LOAD_INDICATION message exceeds the previous value of the RACH load during the measurement period.

NOTE! This RACH counter is triggered when the RX Level is above -100dBm. Other detection methods (like CRC or S/N) are not applied. This means that high load on RACH may occur even without a significant number of CHANNEL_REQUIRED mes-sages. For example, RACHs from different MSs can clash and cause a high signal level, but the decoding does not find any detectable RACH. The interference causes lot of bursts that trigger the counter, but these bursts are then filtered out in the detec-tion.

Counter ID: 003053 Network element name: AVE DRX AGCH LOAD AIR

Version: 3.0 NetAct name: AVE_DRX_AGCH_LOAD_AIR_SUM

Description: Average radio interference CCCH load radio block occupancy DRX AGCH.

It is used to carry information on the Radio interface load of the associated CCCH timeslot. The range of this parameter is 0...100% with 1% intervals. The radio block occupancy percentage for AGCH messages requiring DRX (occupied radio blocks vs. all radio blocks during reporting period) is calculated and reported in CCCH_LOAD_ IND message.


Updated: When a CCCH_LOAD_INDICATION message is received from the BTS. The average DRX AGCH LOAD AIR value is added to the previous value and the number of events is increased by one.

When CCCH_LOAD_IND message is received by BSC and phase 2 BTS or newer is supported. See figure CCCH load indication if GPRS is activated in BTS and other conditions are valid

In the figure a failure can occur between the first and last position, causing counter 3029 to be updated immediately. Signalling between the first and last position can be partly missing depending on where the failure takes place. Such situations can be caused by timer expiries while waiting for ESTABLISH_CONFIRM message, an ERROR_INDICATION or RELEASE_INDICATION message that is received instead of an ESTABLISH_CONFIRM message, or a corrupted ESTABLISH_CONFIRM message.
