Key Performance Indicators

This chapter covers the following topics;

Network Performance Measurement

Network Performance Measurement In GSM, performance of the network can be analyzed through KPIs. KPIs are the specific counters, which represent statistics of overall performance of the network. Network performance judgment such as about resource status, service status or channel quality is possible through these statistics. Statistics comes from the basic measurement of the Control System. Degradation in the performance of the specific cells can be identified in OMCR by analyzing the KPIs. In this way specific problem can be resolved accordingly.

Table 4 lists the entire Key Performance Measurement Counters.

BTS Measurement

This chapter covers the following topics:

Power Control Measurement

TRX Service Measurement

Paging Messages Measurement

TRX Basic Measurement

TRX Power & Temperature Measurement

Power Control Measurement Power Control enables the mobile station and/or the BTS to increase or decrease the transmission power on a per-radio link basis.

Power Control is separately performed for the uplink and downlink. In both cases the BSC is responsible for initiating Power Control; the mobile station and the BTS adopt transmit power according to the BSC Power Control commands.

Two modes of power control are:

Normal power control

Rapid power control

Amplitude of power adjustment in rapid control is greater than normal power control.

BTS regularly samples the power of MS and BTS itself, to obtain average power. BTS regularly reports the average power to BSC through PC TEST RPT message, for power control. Measurement report helps in analyzing the coverage quality as well as the effect and rate of power control.

Wireless Channels


Channels Measurement

Channels Measurement Channel Measurement here means wireless channel measurement in a cell, as mobile communication is always through wireless medium. It refers to the measurement of channel properties, which directly affects the Quality of Service (QoS) in wireless communication, in a particular cell. Channel properties such as received level, received quality, Timing Advance (TA) and interference of both uplink and downlink signals. These measurements are for the channels in busy or idle modes.

BTS sends MS measurement report to BSC every 480ms. BSC measures uplink and downlink signal, TA and RQ value in a channel. BSC updates interference band in database when it receives measurement report from BTS.

Random Access


Random Access Measurement

Random Access Measurement Random access measurement provides statistics such as number of:

Random access attempts

Random access processes

Successful random accesses

For random access slot-aloha is used as an access protocol. Single access may have multiple random access requests.

Random access success ratio means of number of successful random accesses divided by successful random access requests. This ratio reflects the channel blocking status.

Collision may occur between numbers of random access requests, for which time interval adjustment is required.

TCH/F Measurement


TCH/F Measurement Counters.

TCH/F Counters TCH/F measurement counters provide statistics for the following channels:

TCH/F allocation requests

TCH/F allocations

TCH/F assignment requests

TCH/F assignments

TCH/F handover requests

TCH/F handovers

Two types of Assignment flow:

Immediate Assignment

Common Assignment

Immediate Assignment: MS originates the assignment request, which BSC has to fulfill.

Common Assignment: MSC originates the assignment command for the MS.

FIGURE 9 and FIGURE 10 illustrates the two types of assignment flows.

SAPI 3 Measurement

SAPI 3 Counters

SAPI 3 Introduction The SAPI is a 6-bit field in LAPDm and defines the type of user to which a message is addressed. Possible values of SAPI on Air-interface is SAPI=3 and SAPI=0. In this chapter SAPI 3 indicates SAPI=3.

This chapter only discusses the SAPI value equals to three (SAPI=3). SAPI value equals to three (SAPI=3) is used for Supplementary Services (SS) and Short Messages Services (SMS) on Air-interface.

If MS sends Short Message (SM), means MS originated SM (MO-SM). Similarly if MS receives Short Message (SM), means MS terminated SM (MT-SM). On the air interface SACCH/F, SACCH/H, SDCCH, FACCH/F and FACCH/H transport short message. Present system implements counters for SACH/F, SACH/H and SDDCH.

General Handover Measurement


Handover Counters

Handover Counters General Handover measurement involves handover counters that provide statistics for handover processes that arises from all types of handover causes. These counters show handover success ratio, number of handover attempts, execution, success and failure. This chapter analyzes handover in aspect of the control entity and provides statistics for both the executions and handover successes. These counters show statistics for request, success and failure of intra-cell handover, intra-BSC inter-cell handover and intra-MSC handover.

Table 19 lists all the handover counters.

A-interface Signal Measurement

This chapter includes counters that provide signaling statistics over the A-interface. This Chapter covers following topics:

BSSAP Message Counters

BSSMAP Message Counters

BSSAP Message Counters Signaling over A-interface is in the form of Base Station Subsystem Application Part (BSSAP) messages. BSSAP itself can be separated into the base station subsystem management application part (BSSMAP) and the direct transfer application part (DTAP).

BSSMAP include all messages exchanges between BSC and MSC that are actually processed by the BSC. Examples are Paging, Handover and Reset messages.

DTAP messages comprise all messages exchanged between subsystem of the NSS and MS. DTAP messages are transparent for the BSS. DTAP messages carry Call Control (CC) and Mobility Management (MM) information.

SMM Assignment Counters

SMM Handover Counters

SMM Call Drop Counters

SMM Assignment Counters SMM Assignment Counters provide statistics for the successful and failed assignments due to different causes, but actually processed by SMM.

Assignment Process Assignment process involves following steps:

1. MSC sends ‘Assignment Request’ message to the SMM through A-interface.

2. SMM checks the circuit status and searches database for the available circuit.

3. SMM also checks the circuit attributes such as circuit rate and voice version.

4. SMM sends ‘Assignment Request’ message to the RMM.

Measurement value Same as the above calculation

Time Time

n

n = Number of times for the System to occupy the trunk circuit

Previous record time = current time

Calculation Formula

Total occupied Time= (Current Time – Previous Represents Time) * n

Previous Represents Time = Current time.

Where:

n: number of times system occupies the trunk circuits.

Current Time: Time instance at which system occupies the trunk circuits.

Previous Represents Time: Time instance at which system occupied the trunk circuit last time.

(Current Time - Previous Represents Time): occupied time for the trunk circuits.

Another way to calculate the Total occupied time is to accumulate the occupied period at discrete time instances, during the single measurement cycle.

Measurement point

Total occupied time is calculated on three time instances;

When system successfully occupies the trunk circuit

Before system has to releases the trunk circuit


C20605 Definition

System represents the congestion time once the congestion mark is set on the trunk circuit in database. System clears the congestion mark once the trunk circuit is released.

Measurement formula

If congestion mark is set on, the Total Congestion Time at this point can be calculated as follows.

Total Congestion Time= (Release Time – Previous record congestion Time)

Where;

Release Time: Time instance at which system releases the trunk circuit.

Previous Record Time: Time instance at which system applies for the trunk circuit, but it unavailable due to congestion.

Another way to calculate the Total Congestion Time is to accumulate the congestion period at discrete time instances, during the single measurement cycle.

Measurement point

Total Congestion Time is calculated on three time instances;

When system successfully occupies the trunk circuit

Before system has to releases the trunk circuit
