Sub Cell Statistics

Task of sub cell statistics is to measure channel and handover status among sub cells, with focus on traffic sharing condition at the second sub cell.

This chapter introduces the meaning, usage, and measurement point of sub cell statistics counter.

Overview

Sub cell statistics counter is used to find out operation status of the sub cell in radio environment. It focuses on inter-sub-cell handover and relevant counting at the second sub cell so as to check traffic absorption condition by the second sub cell.

The measurement takes sub cell as the statistics unit.

Sub Cell Statistics Counter Index

Table 5 lists counters related to sub cell statistics.

This counter counts the number of intra-cell handover attempts from the first sub cell to the second sub cell.

This counter is used to find out the frequency of intra-cell handover attempts from the first sub cell to the second sub cell, as one of the parameters to measure radio environment.

When BSC receives measurement reports from MS, it makes handover decision. If it is decided to do intra-cell handover, and current sub cell is the first sub cell, and if handover reason is “too small Ta&PassLoss” or “too large C/I”, this counter increments. The measurement point is A, as shown in Figure 1.

MS TA Measurement This chapter contains detailed information about counters related to MS TA measurement.

Overview

MS TA counters are used to check the value of TA in MS measurement reports. TA can reflect the relative location of MS in the cell. If most of the TAs are in very high level, network planning should be remade, such as, increasing the site density.

The measurement takes cell as the statistics unit.

SAPI3 Measurement This chapter contains detailed information about counters related to SAPI3 measurement.

Overview

MO-SM is short message of mobile originating call; MT-SM is short messages of mobile terminating call. In conversation status, the MS can receive point-to-point message so the mobile caller maybe the other side of receiving short message at one time. On the wireless side, short message could be transmitted by the following five channels: SACCH/F, SACCH/H, SDCCH, FACCHF and FACCHH. So far the statistics counting has been realized by the channel of SACCH/F, SACCH/H and SDCCH.

BSSGP Flow Statistic

BSSGP flow statistics task considers cell as a measurement entity, statistics content includes the number of paging, BVC blocking/unblocking as so on. This chapter introduces the meaning, usage, and measurement point of different BSSGP flow statistics counters.

Overview

BSSGP flow statistics mainly measures the message transmission condition at Gb BSSGP level in GPRS service, to count different signaling messages. This includes the number of packet paging, circuit paging, BVC block, BVC unblock, BVC reset, location request, and location result response, etc.

TRX Measurement

TRX measurement task mainly considers TRX as its object to count its resource distribution, seizure, assignment, traffic, and interference, as an evidence of carrier, channel configuration, and relevant parameter adjustment.

This chapter introduces the meaning and measurement point to measure different performance counters by TRX.

Overview

TRX measurement is to measure the success or failure condition of channel activation, assignment, and handover in the unit of carrier. It also can measure carrier interference band, maximum and minimum UL & DL level condition, to learn the status of different carriers, providing evidence for adjustment and maintenance.

TRX Measurement Counter Index

Table 14 lists counters related to TRX measurement.

PS Basic Measurement (BSC)

PS basic measurement (BSC) aims to make a statistic of the performance related with packet switching service on BSC level.


Overview

PS 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).

Overview

PS 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.

When the DL TBF is created successfully and the TBF type is signaling TBF, the counter increments. The measurement point is similar to those of C900040001 and C901000014.

During the TBF transmission, MS divides the UL LLC frame into RLC blocks and sends them to BSS. Only when BSS correctly receives all these RLC blocks can it recompose the LLC frame. BBS informs MS of the RLC block reception through Packet Uplink Ack. For the reply mode, if any RLC block is lost, MS should transmit again.

The counter counts the number of NACK blocks received on EGPRS UL TBF.

Then counter increments when BSS correctly receives a NACK block. The measurement point is A, as shown in Figure 43.

Number of EGPRS UL TBF establishment with existing UL resource

To accelerate TBF establishment, UPPB caches MS’s UL/DL resource within a period of time. When MS attempts to establish new UL TBF on PACCH, relevant resource is directly assigned to MS if there is resource as indicated by UPPB; otherwise, MS sends request for resource to CMP.

This counter records the number of reestablishing UL EGPRS TBF in released state without having to request for resource.

Number of BSC-controlled inter-cell outgoing handover success

This counter counts the number of successful intra-BSC inter-cell outgoing handovers.

This counter is used to find out the frequency of successful intra-BSC inter-cell outgoing handover. It is one of the parameters that evaluate the handover situation.

During the handover process, when the source cell receives the handover completion message from the target cell, it indicates that MS has accessed the target channel and handover succeeds. In this case, this counter increments. The measurement point is A, as shown in Figure 126.

Number of signaling TCH/H assignment failure

This counter counts the number of failing to assign TCH/H channel as a signaling channel.

After BSC responds to the channel request message to allocate and occupy TCH/H successfully, BSC sends the CHL_ACT message to BTS to activate this TCH/H. If BSC does not receive the MS access notification within a certain time, this assignment fails.
