The data transmission rate that is achieved separately for downloading and uploading specified test files between a remote web site and a user’s computer. Data transmission speed achieved -Maximum data transmission rate in kbit/s achieved; -Minimum data transmission rate in kbit/s achieved; -mean value and standard deviation of the transmission rate in kbit/s achieved; ETSI EG 202 057-4 Data transmission achieved should be at least 80% of that advertised by the service provider. Note: ETSI EG 202 009-2 (2007-01) may be consulted for user related parameters on a service-specific basis. The guide includes parameters with respect to web browsing, web page hosting, email, etc. Q.9 Do you agree with the proposed set of QoS parameters for Internet services? Q.10 Do you agree with the target values proposed for Internet services? If not, please suggest other benchmarks. 4.2 Proposal for Measurement and Auditing of Results Once the list of QoS parameters and their target values have been agreed upon, it is proposed that same be formalised in an appropriate regulatory instrument, e.g. some directives on QoS. The next important step of the monitoring process is then the measurement of the QoS parameters and subsequent reporting and auditing of results as may be appropriate. The following options are proposed for QoS measurements and auditing: (i) Measurements made by operators and audited by the regulator; (ii) Measurements made by operators and audited by an independent agency; (iii)Measurements made by an independent agency- in which case no further auditing would be required. 4.2.1 Measurements made by Operators Where it is agreed that operators make the measurements, the way these measurements are to be made and the format in which they should be reported to the Authority should be clear and agreeable to all; since even with uniform parameters the way of collecting and collating data may vary for different operators. Some reference measurements methods recommended by ETSI have been reported in the previous section. 25
Only part of the measurements may be audited either at random or upon complaints or suspects of falsification. Prior to auditing, the following issues need to be addressed: o Determine the main QoS parameters to be audited for the services of interest. o Define in details the methodology for auditing. o Determine the sampling methodology for auditing. (i) Auditing Activities It is proposed that the main activities under this audit to include:- o Auditing the raw data/records maintained by service providers to check the veracity of data reported by the latter. o Conducting drive-around tests (either operator-assisted or independent drive tests) to verify quality of service especially for mobile services. Parameters such as dropped call ratio, unsuccessful call ratio, blocked call rate, voice quality may be determined by this method. It is proposed that the drive-around be done at similar times, between similar places and in similar circumstances for all mobile telephony operators. o Performing live tests on a sample basis to check parameters related to efficiency of customer care e.g. service provision, complaint resolution time, directory enquiry, etc. o Making live measurements to assess the network performance of service providers through live figures recorded from servers over, for instance, a three-day period. (ii) whether auditing is to be done by the regulator or an independent external agency; In case it is agreed to appoint an external independent agency for the auditing job, a tender process should be initiated by the Authority. It is proposed that requirement of this tender be worked out by the Authority in consultation with other stakeholders. In the event that the Authority itself carries out the auditing job, then the necessary monitoring equipment should be purchased by the Authority. The technical requirements of the monitoring equipment should be worked out and a tender process initiated accordingly. 4.2.2 Measurements outsourced to independent agency The measurement exercise may otherwise be outsourced to an independent agency. One approach may entail the Authority contracting an industry expert in QoS measurement to design, build and operate a test platform in Mauritius, with the objective of continuously monitoring and reporting on the service quality of different operators. 26
