The benchmark for call drop set by TRAI is 2% as it is not possible to achieve 100% call retention. As per the access license, the operators are required to provide 90% street coverage. These benchmarks are seldom achievable. There has been a two-fold jump in call drops on 2G networks and 65% on 3G networks in a one-year period. As per a weekly data submitted by the operator, 35,654 sites out of 1.88 million base tower station sites accounted for more than 3% of call drops.<\/p>
Recently telecom operators have improved the performance of 15,549 sites to reduce the call drops whereas 17,200 sites are yet to be improved. As per telecom operators, about 7000-10,000 sites have been locked or shut down across major cities by the government and hence they have sought a uniform national policy for installation of mobile towers.<\/p>
There are several reasons for call drop. The call drop rates in major cities like Delhi and Mumbai are highest in India. Some major sites in Delhi account for 17.29% of call drops while Mumbai has 5.56% of call drops which is much above the 2% benchmark despite significant infrastructure investment in these 2 cities (INR 2.11 trillion in 2014 and INR 2.02 trillion in 2013).<\/p>
\u2022 Fragmented Spectrum:<\/strong> The frequency allocation in India is fragmented and operators hold small chunks of spectrum due to small quantum of spectrum put for auction and competitive market while new technology and high quality of service requires contiguous spectrum. The average spectrum available with operators in India is 13-15 MHz in comparison to 60-100 MHz in China. India has just 0.1 MHz spectrum per million population while European countries have 3-6 MHz.<\/p> \u2022 Debt burden:<\/strong> The debt burden rose to INR 3.5 trillion after the spectrum auction due to high price of spectrum and infrastructure. Telcos also pay a huge share i.e. almost 25% of their revenue as taxes to the government. The players are reluctant to upgrade technology and infrastructure because of the financial burden.<\/p> \u2022 Strict regulations:<\/strong> The radiation norms in India is far more restrictive in global comparison which limits the capability of towers to serve more subscribers and in addition to that towers are being sealed in major cities due to health concerns which has affected the service delivery and is a major concern for high call drop rates. Other countries like Brazil have addressed call drops by strengthening the network, efficient utilization of spectrum, etc.<\/p> The following could help address the call drop problem: 调用下降问题是印度电信景观严重伤害几乎80%的收入仍记录单从语音段。印度是世界上第二大电信市场拥有10亿用户,因此电信公司在全球的大市场。但是网络的质量差、缺乏最新的技术和基础设施,分散光谱电信和金融负担直接影响服务质量。 火车是设定的基准叫下降2%,叫保留不可能达到100%。根据访问许可证,要求运营商提供90%的街道覆盖率。这些基准很少实现。有双重的跳在2 g网络和电话滴65% 3 g网络在一年的时间。根据每周数据提交的操作符,35654个网站的188万个基塔站网站占超过3%的下降。 最近电信运营商提高了15549个站点的性能,减少电话滴而17200网站有待提高。根据电信运营商,7000 - 10000网站被锁定或关闭在主要城市的政府,因此他们寻求一个统一的国家政策移动基站的安装。 有几个原因叫下降。调用下降率在德里和孟买这样的大城市在印度最高。一些主要站点在德里占17.29%的下降而孟买有5.56%的下降,远远高于2%的基准,尽管在这两个城市重大基础设施投资(INR 2.11万亿年2013年2014年和2.02万亿年INR)。 •支离破碎的光谱:频率分配在印度支离破碎和运营商拥有小块由于小量子谱的频谱拍卖和竞争激烈的市场中,新技术和高质量的服务需要连续的光谱。平均可用频谱与运营商在印度是13 - 15 MHz相比在中国60 - 100 MHz。印度刚刚0.1 MHz频段每百万人口,而欧洲国家3 - 6 MHz。 •债务负担:债务负担上升到印度卢比3.5万亿频段的频谱拍卖由于高价格和基础设施。电信公司也付出巨大份额即近25%的收入作为政府的税收。球员不愿意升级技术和基础设施的财政负担。 •严格规定:印度的辐射标准更严格的全球对比这限制了塔的能力服务更多的用户,除了塔被密封在主要城市由于健康问题影响了服务交付和是一个主要关心通话掉线率高。 其他国家像巴西解决电话滴通过加强网络,有效利用频谱等。 以下可以帮助解决通话掉线问题:
Recently the regulator proposed the telcos to compensate the consumers for call drops. Call drop is a localised phenomenon rather than a PAN India problem. To address this issue by compensating the consumer, telcos would need to spend a lot more on upgrading the billing system. Call drop issue is addressed in Bangladesh by offering users free minutes for every dropped call. But the scenario in India is different as there are many other factors along with network infrastructure that affect the call drop directly. Even illegal jammers and wideband repeaters are causing call drops in many places where telcos cannot be made accountable. As per the telcos, 95% of the tariff plans involve billing in seconds and they gain nothing in such cases in a call drop scenario. One of the incumbents shifted all its prepaid customers to second based billing to address the compensation issue.<\/p>
1. Recently announced spectrum sharing and trading rules are expected to help address the problem.
2. In addition, spectrum refarming could help to rationalise spectrum bands across the operators.
3. Release of spectrum in lower frequency bands (700 MHz, 800 MHz) can also improve throughput of network with lesser number of towers.
4. Liberal policies and regulations in infrastructure sharing would be best solution to address infrastructure shortage and quality issues in India.
5. Liberal policies on tower infra in non-commercial sites and right of way policies could help address the problem proactively.<\/p>","blog_img":"retail_files\/blog_1446707700_temp.jpg","featured":0,"status":"Y","seo_title":"Call drop solution: Compensation or root cause analysis","seo_url":"call-drop-solution-compensation-or-root-cause-analysis","cms_link":"call-drop-solution-compensation-or-root-cause-analysis\/1003","updated_at":"2015-11-05 13:02:43","time":"2015-11-05 12:45:01","authors":[{"author_name":"Hemant Joshi","author_description":"Partner, Deloitte India","author_designation":"Partner","author_company":"Deloitte India","profile_pic":"retail_files\/pic_author_1404798937_temp.jpg"}],"tags":[],"url_seo":"call-drop-solution-compensation-or-root-cause-analysis"}">
最近,监管机构提出了电信公司赔偿消费者叫滴。潘叫下降是一种局部现象,而不是一个印度的问题。补偿消费者解决这个问题,电信公司将需要花费更多的时间和精力在升级计费系统。叫下降问题是解决在孟加拉国提供用户免费分钟每一个通话掉线。但在印度的场景是不同的还有很多其他因素以及网络基础设施影响直接调用下降。甚至非法干扰器和宽带中继器造成电话滴在许多地方电信公司无法负责。按照电信公司,95%的关税计划包括在秒计费和他们在这种情况下在叫下降的情况下。的一个基于现有所有预付的客户转移到第二个账单解决赔偿问题。
1。最近宣布频谱共享和交易规则将帮助解决这个问题。
2。此外,光谱refarming可以帮助运营商合理化谱带。
3所示。释放在低频段的频谱(700 MHz、800 MHz)也可以提高网络吞吐量较小数量的塔。
4所示。自由政策和法规在基础设施共享将是最好的解决方案,以解决在印度基础设施短缺和质量问题。
5。自由塔下文政策在非商业网站和权政策可以帮助解决问题主动。
