VoLTEサービスアシュアランス:ベンダーおよびオペレーターにとっての市場機会と課題 VoLTE Service Assurance: Opportunities and Challenges for Vendors and Operators
出版日: 2014年10月02日 ページ情報: 英文 PPT and PDF (41 slides)





  • SRVCCによるネットワークの複雑性の増大・サービスアシュアランスシステムにツァラなる要件を付加
  • IPプローブおよびエンドツーエンドのパフォーマンスモニタリングへの支出額:オペレーターがIMS・VoLTE向けアシュアランスシステムの導入および拡張を行う中で成長する見通し
  • IMSおよびLTEアシュアランスへの支出額はレガシーCS音声が衰退する中で成長する見通し:幅広い対応力を持ったベンダーが利益を享受する見通し


  • 提言


  • VoLTEサービスアシュアランスへの支出額のサービスアシュアランス市場全体に占めるシェアの予測
  • 地域・オペレーターに固有の特徴があることから、積極的なVoLTEの利用が世界的な動向となるとはいえない
  • 欧州・中東・アフリカ地域および北米地域がVoLTE向けCOTSサービスアシュアランスソリューションの支出額で大半のシェアを占める見通し
  • 市場成長推進因子・阻害因子


  • VoLTEは大きなメリットを確約しているが、事例が貧弱で、LTEへの依存度も低いためフルスケールの導入速度は遅い
  • SRVCC技術によるIMSベースのVoLTE:サービスアシュアランスシステムにもっとも大きな影響を持っている
  • アシュアランスベンダー:VoLTEの開始前・開始後で役割が変化する
  • オペレーターはVoLTEトラフィックのモニタリングに対する需要拡大に対応するため、IPプローブの導入を拡大する見通し
  • エンドツーエンドのQoSアシュアランスはオペレーターのVoLTEサービスアシュアランス戦略の中核的テーマを形成する必要がある
  • パフォーマンスデータはQoSの測定とトラブルシューティングのため、各種ネットワークインターフェースから収集され、リアルタイムに近い時間で関連付けされる必要がある
  • VoLTEアシュアランスの包括的アプローチはパケット交換網・回線交換網の両方をカバーしたQoSを測定する必要がある
  • VoLTEサービスマネジメントアプリケーションは、CEMなどの主要な事業目標に対応するため、非常に重要な価値を持つ
  • アシュアランスソリューションは重複した呼び出しのシナリオを検討する必要があるが、開始当初は初期にはVoLTE-to-VoLTEコールのみを提供する傾向にある


  • 将来のLTEの接続数およびモバイル接続に占めるシェアの拡大
  • デフォルトとしてVoLTEを利用するスマートフォンユーザー数の予測
  • VoLTEのサービスを開始するオペレーターの数と試験中のオペレーターの数


著者/Analysys Masonについて


Vendors that have a diverse mix of assurance capabilities covering LTE, legacy CS voice and IMS will be well-placed to win VoLTE assurance contracts.


Voice over LTE (VoLTE) enables operators to fully migrate customers to LTE and accelerate take-up of new data services, at the same time as improving spectral efficiency. However, the quality of service (QoS) expectations of a voice service and the inherent technology complexity of VoLTE will require investments in service assurance systems.

This report provides:

  • a 5-year forecast of the VoLTE service assurance market
  • analysis of the factors driving and inhibiting investments in VoLTE service assurance
  • challenges confronting operators in assuring VoLTE
  • detailed discussion of service assurance considerations and opportunities, including:
  • impact of VoLTE solutions on service assurance and capabilities needed
  • service assurance considerations for VoLTE solutions
  • service assurance vendors' pre- and post-launch roles in VoLTE deployments
  • voice QoS measurement techniques
  • VoLTE service management application architecture and VoLTE call scenarios
  • recommendations for communications service providers (CSPs) and suppliers
  • analysis of the business environment
  • vendor analysis for key service assurance players.

Table of Contents

  • 5.Executive summary
  • 6.Spending on service assurance for VoLTE will reach USD413 million by 2018, driven by Tier 1 operators with mature LTE coverage
  • 7.SRVCC introduces significant network complexity that places additional requirements on service assurance systems
  • 8.Spending on IP probes and end-to-end performance monitoring will grow as operators deploy and scale assurance systems for IMS and VoLTE
  • 9.Spending on IMS and LTE assurance will grow as that on legacy CS voice declines, so vendors with diversified capabilities in these areas will benefit
  • 10.Recommendations
  • 11.Recommendations
  • 12.Forecast
  • 13.VoLTE service assurance spending will account for 10% of the total service assurance market by 2018
  • 14.Unique regional and operator characteristics pointing to aggressive VoLTE take-up will not indicate a general worldwide trend
  • 15.EMEA and NA will account for 73% of spending on COTS service assurance solutions for VoLTE by 2018
  • 16.Market drivers and inhibitors
  • 17.Service assurance considerations and opportunities
  • 18.VoLTE promises significant benefits, but full-scale adoption will be slow because of a weak business case and dependency on LTE coverage
  • 19.IMS-based VoLTE with SRVCC technology has the greatest impact on service assurance systems

  • 21.Operators will increase deployment of IP probes to cater for the increased demand for monitoring VoLTE traffic
  • 22.End-to-end QoS assurance must form the central theme of operators' VoLTE service assurance strategy
  • 23.Performance data must be collated from different network interfaces and correlated in near-real time for measuring QoS and troubleshooting
  • 24.A holistic approach to VoLTE assurance will need to measure QoS covering both packet-switched and circuit-switched networks
  • 25.A VoLTE service management application will be of significant value to operators because it will cater for key business objectives such as CEM
  • 26.Assurance solutions must consider multiple call scenarios, but initial launches are likely to offer only VoLTE-to-VoLTE calls
  • 27.Market environment
  • 28.LTE connections will increase twenty-fold from 80 million in 2012 to reach 1.60 billion in 2018, accounting for 19.7% of mobile connections
