Zero-rating (also called ''toll-free data'' or ''sponsored data'') is the practice of mobile network operators (MNO), mobile virtual network operators (MVNO), and Internet Service Providers (ISP) not to charge end customers for data used by specific applications or internet services through their network, in limited or metered data plans.〔(【引用サイトリンク】 title=Facebook’s plan to find its next billion users: convince them the internet and Facebook are the same )〕 It allows customers to use provider-selected content sources or data services like an app store,〔 〕 without worrying about bill shocks, which could otherwise occur if the same data was normally charged according to their data plans and volume caps. This has especially become an option to market 4G networks, but has also been used in the past for SMS or other content services. In combination with zero-rating some services, MNOs are typically setting relatively low volume caps for open internet traffic or conversely, over-pricing open internet data volumes. Choosing to ''zero-rate'' existing third-party services trending among an attractive audience for the mobile network operator allows to increase or defend market share for the target segment. This price discrimination works also in favour of the chosen third party service. Building their own services and delivering them at a zero-rate if bundled with their mobile contracts has also been a common practice among mobile operators. In this scenario, network operators can optimize their service together with their network to deliver an optimal service. Together with the existing billing relationship, this can be an important factor to compete with third party services or take control over volume-heavy services. == Existing programs == Internet services like Facebook, Wikipedia and Google have built special programs to use zero-rating as means to provide their service more broadly into developing markets. The benefit for these new customers, who will mostly have to rely on mobile networks to connect to the Internet, would be a subsidised access to services from these service providers. The results of these efforts have been mixed, with adoption in a number of markets, sometimes overestimated expectations and perceived lack of benefits for mobile network operators. In Chile, the national telecom regulator ruled that this practice violated net neutrality laws and had to end by June 1, 2014. Since June 2014, U.S. mobile provider T-Mobile US has offered zero-rated access to participating music streaming services to its mobile internet customers.〔(【引用サイトリンク】url=http://www.theverge.com/2014/6/18/5819804/t-mobile-unradio-rhapsody-free-internet-radio-service )〕 Similarly mobile network operators are also able to use the underlying classification technology like Deep packet inspection to redirect enterprise related data charges for employees using their private tablets or smart phones to their employer.〔 This has the benefit of allowing employees to participate in ''Bring your own device (BYOD)'' programs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zero-rating (also called ''toll-free data'' or ''sponsored data'') is the practice of mobile network operators (MNO), mobile virtual network operators (MVNO), and Internet Service Providers (ISP) not to charge end customers for data used by specific applications or internet services through their network, in limited or metered data plans.(【引用サイトリンク】 title=Facebook’s plan to find its next billion users: convince them the internet and Facebook are the same ) It allows customers to use provider-selected content sources or data services like an app store, without worrying about bill shocks, which could otherwise occur if the same data was normally charged according to their data plans and volume caps.
