A value-added service (VAS) is a popular telecommunications industry〔(【引用サイトリンク】title=Global Mobile Value Added Services (VAS) Market: Worldwide Industry Share, Investment Trends, Growth, Size, Strategy And Forecast Research Report 2013 )〕 term for non-core services, or in short, all services beyond standard voice calls and fax transmissions. However, it can be used in any service industry, for services available at little or no cost, to promote their primary business. In the telecommunication industry, on a conceptual level, value-added services ''add value'' to the standard service offering, spurring the subscriber to use their phone more and allowing the operator to drive up their ARPU. For mobile phones, technologies like SMS, MMS and data access were historically usually considered value-added services, but in recent years SMS, MMS and data access have more and more become core services, and VAS therefore has begun to exclude those services. Mobile VAS services can be mainly categorized into 3. # Consumer VAS # Network VAS # Enterprise VAS A distinction may also be made between standard (peer-to-peer) content and premium-charged content. These are called mobile value-added services (MVAS) which are often simply referred as VAS. Value-added services are supplied either in-house by the mobile network operator themselves or by a third-party value-added service provider (VASP), also known as a content provider (CP) such as All Headline News or Reuters. VASPs typically connect to the operator using protocols like Short message peer-to-peer protocol (SMPP), connecting either directly to the short message service centre (SMSC) or, increasingly, to a messaging gateway that gives the operator better control of the content. ==Major value-added services== * Mobile TV & OTT Services〔(【引用サイトリンク】work=qtelmedia.com )〕 * Ring Back Tone(RBT & RRBT)〔http://medialabasia.in/images/ITRA_Mobile/Abhinav_Mathur.pdf〕 * SMS Chatting & Dating Premium Services〔(【引用サイトリンク】title=Instant VAS -- SaaS USSD/SMS Platforms, Applications & Games for the Mobie VAS Industry )〕 * Music Tracks Play, download and Ring Tones * Sports and Infortainment Services * Location Based Services * Missed Call Alerts and Voice Mail Box * Online Gaming * Live Streaming * Devotional Applications * Mobile Money & M-commerce based services * Mobile Advertisements * Contests & Voting * Phone Backup and Security Services * Outbound Dialer Services * WAP content downloads * Utility Services * Stickering 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「Value-added service」の詳細全文を読む スポンサード リンク
