ITU-T E.811 (03/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunicatio
14、n Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WT
15、SA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall
16、within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Reco
17、mmendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language su
18、ch as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommen
19、dation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approv
20、al of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB pa

ITU-T E.811 (03/2017) Introduction To ensure a quality of service (QoS) and quality of experience (QoE) in mobile broadband and voice services in and around crowded and large venues, with thousands of people sharing pictures, videos and accessin
27、g social networks simultaneously, is a big challenge for operators and regulators worldwide. This scenario comes as a result of the fast penetration of smartphones and the increase of quality thresholds necessary to guarantee user satisfaction. Taking into account that monitoring strategies to be ad
28、opted by regulators are not well defined yet, the efforts to measure QoS and QoE parameters to assure good quality during major events are based more in empiricism than in standards and trusted technical references. The reports from FIFA World Cup Brazil 2014 and Rio 2016 Summer Olympic Games showed
29、 the explosion of voice, data and SMS traffic during the events, not just inside the game venues at the host country but in many regions around the world, due to the massive sharing of pictures and videos in social media and streaming applications. In this scenario, the biggest challenges faced by o
30、perators is to forecast the traffic demand and then deploy an infrastructure that mix 2G, 3G, 4G, 5G and Wi-Fi offloading approaches to ensure the quality of mobile services during the events, especially inside and around the crowded stadiums. Given the lack of technical references for this specific
31、 context of service provision, the successful experiences and main issues faced by the previous host countries is sometimes the unique reference. Rec. ITU-T E.811 (03/2017) 1 Recommendation ITU-T E.811 Quality measurement in major events 1 Scope This Recommendation addresses the quality assessment o
32、f mobile broadband and voice services provided during major events, such as FIFA World Cups and Olympic and Paralympic Games, by creating a useful international reference to be considered by operators and regulators when preparing to host major events. This Recommendation covers the following: 1) tr
33、affic forecasting and network dimensioning applied to major events 2) establishing strategies of QoS and QoE measurements during major events 3) identifying the relevant key performance indicators (KPIs) to be measured 4) establishing network capabilities and reasonable thresholds that should be ach
34、ieved to assure users satisfaction in the context of major events. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
