Plan of the presentation Introduction: QoS background Senegal, Dakar, March 24-25, 2015 7
Background for the Follow up of QoS/QoE ANRT QoE Portal and downloaded applications Device for QoE : Adoption of a communication strategy (publication) An international regulatory framework (standards) : - ITU-T: series E, G, P, Y, QoS Handbook, ... - Regional: ETSI (EG-series), IEEE,... A national regulatory framework: - Responsibilities -QoS obligations for operators A benchmark of best practices and a technological watch The ANRT exercised a steady monitoring of the QoS Use feedbak: - Complaints, - Press, - Associations of consumers, - ... Analysis of the data received from the operators in terms of performance, KPIS and QoE measures. Measures on the field (campaigns) carried out by the ANRT 8
Background for the Follow up of the QoS Full operational Model of KPI data according to the fixed frequencies Establishment of a comprehensive system of reception of KPI of operators: all networks and all services Mastered Externalisation of measures and use of the results by the operators Elaboration of reference documents agreed by all the actors regulating the field measures of the QoS 9
Background for the follow up of the QoS Methodology for the Evaluation of the Quality of service QoS Data for the 3G networks (UMTS or CDMA2000 on PC or SP) is perf ectly valid and adapted for broadband mobile Networks : 4G ( ), Wifi Outdoor (offloading ) ,... 10 Senegal, Dakar, March 24-25, 2015
Plan of the Presentation Types and conditions of Measures QoS : Mobile Internet 3G on PC, Mobile Internet 3G Smartphones on Measures FTP or HTTP 11 Senegal, Dakar, March 24-25, 2015
QoS of the Mobile Internet 3G Types and conditions of QoS Measures : Mobile Internet 3G on PC: USB dongles (Prepaid Or Post- Paid) on computers for the UMTS or the CDMA-2000. Mobile Internet 3G on Smartphones: SIM/ 3G for subscribers on SP/tablets only for the UMTS. Measures in FTP mode or HTTP : to be carried out with sized Files for measures (Up/Dw): 1Mb, 5Mb, ... 12 Senegal, Dakar, March 24-25, 2015
QoS Of The Mobile Internet 3G Types and conditions of QoS Measures : Evaluation of the QoS Evaluation of the Coverage. Any Measure must be carried out only in the areas declared fully covered by all the operators at the same time : exercise of geographical sample and the map of coverage. The exercise of mapping of coverage must be done with full detail of the quarter and not with that of the City. 13 Senegal, Dakar, March 24-25, 2015
Plan of the presentation Measured Indicators 14
QoS of the mobile Internet 3G For each type of measure, what indicators are relevant? Jitter, delay, debit, loss of data, etc. ? Pragmatic objectives (by satisfaction survey) relevant for user experience : measure the accessibility (Rate and connection time), the reliability and the speed (debit of transmission and reception). Transformation of these elements in ten (10) indicators: 15 Senegal, Dakar, March 24-25, 2015
QoS Of The Internet Mobile 3G List of the ten (10) measured Indicators : The rate of successful connections: A connection is successful if it is established in a period of less than 1 minute. The rate of successful connections is calculated on the basis of all of the measures carried out. The rate of successful connections in a period of less than 10 seconds: The rate of successful connections in a period of less than 10 seconds is calculated on the basis of all of the measures carried out. The rate of files of 1 Mb sent within a period of less than 2 minutes: A file is considered to be sent if the file is sent fully within a period Dmax And if its content is correct. The rate is calculated on the basis of the total number of files sent. The rate of files of 5 Mb received within a period of less than 5 minutes: A file is considered received if the file is received in full and if its content is correct. The rate is calculated on the basis of the total number of downloaded files. 16 Senegal, Dakar, March 24-25, 2015
QoS Of The Internet Mobile 3G List of the ten (10) measured Indicators : The data debit achieved for 90% of the files of 1 Mb sent: This indicator corresponds to the percentile at 90 per cent of the files sent. The data debit achieved for 50% of the files of 1 Mb sent: This indicator corresponds to the percentile at 50 per cent of the files sent. The data debit achieved for 10% of the files of 1 Mb sent: This indicator corresponds to the percentile at 10 per cent of the files sent. 17 Senegal, Dakar, March 24-25, 2015
QoS of the Mobile Internet 3G List of the ten (10) measured Indicators : The debit of data achieved for 90% of the files of 5 Mb received : This indicator corresponds to the percentile at 90 per cent of the files sent. The debit of data achieved for 50% of the files of 5 Mb received: This indicator corresponds to the percentile at 50 per cent of the files sent. The debit of data achieved for 10% of the files of 5 Mb received: This indicator corresponds to the percentile at 10 per cent of the files sent. 18 Senegal, Dakar, March 24-25, 2015
QoS of the mobile Internet 3G Measured Indicators : Important Details: The debit for the 3G networks is a debit shared between all users. The actual debit (operated) is always Lower than the theoretical one (marketed). It is a technological consideration. But this debit is measurable for all the operators with the same device. 19 Senegal, Dakar, March 24-25, 2015
QoS of the Mobile Internet 3G Additional Indicator: TUDC The Rate of use of the contractual debit (TUDC) corresponds to the relation between the used debit (observed) and the contractual one (marketed) in the relevant operator s. This relation is expressed in percentage. An actual Example for a 3G network. 36.23% 40.00% D bits observ s/ D bits commercialis s (en %) (D bit atteint par 50% des fichiers re us) 100.00% 90.00% 80.00% 70.00% 60.00% 54.10% 48.83% 50.00% 41.80% 39.53% 31.64% 30.00% 24.61% 20.00% 10.00% 0.00% Casablanca Rabat Agadir Marrakech F s Tanger Moyenne nationale 20 Senegal, Dakar, March 24-25, 2015
Plan of the presentation Platform of servers of Measures 21
QoS Of the mobile Internet 3G Platform of servers of measures: Measuring the performance of a 3G mobile Internet network is performing measurement of the QoS of a connection through this network between a terminal and a data server. Several external factors may impact on one of the segments of the test path. Hence the challenging of the results of measures by the relevant operator. The option of measures with an international server must be set aside. 22 Senegal, Dakar, March 24-25, 2015
QoS of the 3G mobile Internet Platform of servers of measures: Problem: Lack of server (among the hosts), at the national level, connected to all the networks with a capacity greater than the highest debit offer!!! Solution: design of a platform of servers of measures at the level of the regulator s premisses.The capacities of the links are greater than the measured debits (example 10Mb/s to measure 7.2 Mb/s and 20Mb/s to measure 14.4 Mb/s). 23 Senegal, Dakar, March 24-25, 2015
QoS of the 3Gmobile Internet Platform of servers: All the test files are installed in each server of the platform connected by FO to the 3G network of the operator. 24 Senegal, Dakar, March 24-25, 2015
Plan of the presentation Measurement Tools 25
QoS of the 3G Internet Mobile Tools of Measures (Precautions) Terminal Equipment (PC, SP, and dongles/USB) , Criteria Of Choice : Choose among the industrial models the most used in the national market. With performing characteristics that do not curb the the highest measured debits. For the PC (OS, firewalls, antivirus, etc. ) and for the Terminals (Twindowsize, MTU, CPU, RAM, etc. ). 26 Senegal, Dakar, March 24-25, 2015
QoS Of The Internet Mobile 3G Tools of measures (Precautions) Profiles of subscriptions used: Post-paid or prepaid. Beware to downgrade of debit if the download volume reached the thresholds. The tests on the SP must be done in 3G strained mode and not in dual (avoid confusion GPRS or EDGE). For each operator (a server and a link) only one measurement is to be done at once. 27 Senegal, Dakar, March 24-25, 2015
QoS of The 3G Internet Mobile Tools of Measures Application Software (agents installed in the terminals : PC and SP) : To each data connection, the application records information upwardly for automatic calculation of all the QoS indicators of the connection (level of fields, SC, failures, success, etc. ) as well as the GPS position The application allows you to store directly and automatically all the results (indicators) in a server that centralizes the preparation of the required reports in the framework of the dedicated portal. 28 Senegal, Dakar, March 24-25, 2015
Plan of the presentation Conclusions and recommendations 29
Conclusions and Recommendations Recommendation 1 Permanent consultation with the upstream operators on the methodology. Adoption of a concerted approach of reference for the follow up. Recommendation 2 None of the operators is informed on the sites of the measures or about the period. 30 Senegal, Dakar, March 24-25, 2015
Conclusions and Recommendations Recommendation 3 Achieve a significant number of blank QoS measures with the same tools as those used in the campaigns of actual measures and preferably in the presence of the representatives of the operators concerned by the measures (mitigate or do away with any challenge of potential operators). 31 Senegal, Dakar, March 24-25, 2015
Conclusions and Recommendations Recommendation 4 Measures for operators: positive use of results by the operators (use of the platform test servers//objective potential financing of campaigns by the operators). Recommendation 5 Publish the results (comparative), adopt a communication strategy and consider The sanctions For the anomalies as Last resorts. 32 Senegal, Dakar, March 24-25, 2015
Conclusions and Recommendations Recommendation N 5 ( further part) Publication of the results of measures: 1stvoice campaign on a large sample (about thirty cities and concentration points airports, tourist centers etc. ). 1ERQuarter of the year Communication of results to operators 2ndcampaign similar to the first based on practically the same sample. 4ThQuarter of The year Deadline within 5 to 6 months for Correction of abnormalies identified by the ANRT (Publication of Results and communication) 33 Senegal, Dakar, March 24-25, 2015
