PS Basic Measurement (BSC)PS basic measurement (BSC) aims to make a statistic of the performance related with packet switching service on BSC level. This chapter describes the definition, usage and measurement point of various counters.

OverviewPS basic measurement (BSC) consists of statistic of the number of bytes received from data link and bytes sent to data link. The measurement takes BSC as the statistics unit.

PS Basic Measurement (Cell)PS basic measurement (Cell) collects formation of the PS service (Cell) performance. This chapter gives detailed information about the PS basic measurement (Cell).

OverviewPS basic measurement (Cell) involves the ordinary counters used to measure the PS service performance and status, such as the uplink (UL) /downlink (DL) TBF counter, the flow counter, the UL/DL PACCH counter, the UL/DL RLC counter, the UL/DL GPRS data counter, the UL/DL EGPRS data counter, and the PS resource counter. The measurement takes cell as the statistics unit.

C900040002Definition DescriptionNumber of GPRS DL TBF release due to N3105 overflow

During the DL TBF transmission, the DL block RRBP bit is set to ask MS to respond with a Packet Downlink Ack/Nack message. If the specified block of BSC fails to receive response from MS, then the N3105 counter increments; otherwise, it has a clear. If no response comes from the MS, then the RRBP bit is set again to ask MS to respond with a Packet Downlink Ack/Nack message; if the N3105 counter reaches its maximum value, it is considered that the radio transmission fails and the DL TBF is released abnormally.

Measurement Point

When the N3105 counter value exceeds N3105Max, this counter increments. The measurement point is A1, as shown in Figure 4.

When the user plane is transmitting the DL TBF, at least one block must be transmitted in every 5 seconds. After a DL TBF block is transmitted, BSC will start or restart a 5-second DL block assigning timer. If the timer expires, it is considered that the user plane has an instance suspension and the DL TBF is released abnormally. When the DL block assigning timer expires, this counter increments. The measurement point is A, as shown in Figure 7.

This counter counts the number of establishments of GPRS DL TBF for UL signaling transmission. The UL signaling involves some UL processes such as ATTACH, PDP activation, and routing area update. Measurement Point When the DL TBF is created successfully and the TBF type is GPRS signaling TBF, the counter increments. The measurement point is similar to those of C900040001 and C901000014.

C900040009Definition Description Measurement Point Number of EGPRS DL TBF establishment success on PACCH This counter counts the number of successful DL EGPRS TBF establishments on the UL/DL EGPRS TBF PACCH. When the DL EGPRS TBF is established on the UL/DL EGPRS TBF PACCH and a message indicating assignment success is sent, this counter increments. The measurement points are A as shown in Figure 1 and Figure 2, and A2 as shown in Figure 3.

C900040010Definition Description Number of EGPRS DL TBF release due to N3105 overflow During the DL TBF transmission, the DL block RRBP bit is set to ask the MS to respond with a Packet Downlink Ack/Nack message. If the specified block of BSC does not receive the MS response, then the N3105 counter increments; if it does, then it has a clear; if no response comes from the MS, then the RRBP bit is set again to ask the MS to respond with a Packet Downlink Ack/Nack message; if the N3105 counter reaches its maximum value, it is considered that the radio transmission fails and the DL TBF is released abnormally. Measurement Point When the N3105 counter value exceeds N3105Max, this counter increments. The measurement point is A1, as shown in Figure 8.

If the specified block receives the MS response, then T3191 will stop and the DL transmission ends normally. If T3191 overflows, then it is considered that the radio transmission fails and the DL TBF is released abnormally. The measurement point is A1, as shown in Figure 9.FIGURE 9 MEASUREMENT POINT OF NUMBER OF EGPRS DL TBF RELEASE DUE TO OTHER REASONS MS BSC

C900040013Definition Description Number of EGPRS DL TBF release due to instance suspension When the user plane is transmitting the DL TBF, at least one block must be transmitted in every 5 seconds. After a DL TBF block is transmitted, BSC will start or restart a 5-second DL block assigning timer. If the timer expires, it is considered that the user plane has an instance suspension and the DL TBF is released abnormally. When the DL block assigning timer expires, this counter increments. The measurement point is A1, as shown in Figure 11.
