EPC（Evolved Packet Core）は、LTEアクセス用の3GPP規定のコアネットワークで、LTEシステムアーキテクチャの中核を成し、サービスの提供には不可欠です。時間とともに、2G/3Gネットワークにおけるパケット交換サービスの共通コアネットワークとして期待されるようになり、Wi-Fiアクセス統合への優先ポイントとして浮上しています。
The Evolved Packet Core (EPC) is the 3GPP-specified core network for LTE access. It is central to the LTE system architecture and is critical to delivery of services. Over time it is also expected to become a common core network for packet-switch services in 2G and 3G networks, and is emerging as a preferred point of integration for Wi-Fi access.
By virtue of its position at the heart of the mobile network, the EPC must interact with multiple internal and external domains to mesh together the complex web of elements needed to create and deliver services to end-users in way the operator can monetize and scale. Above and beyond the basic mobility, security and subscriber management functions, this role of "service-enabler" is what makes EPC strategic to mobile operators, and takes it from being a cost-center to being a business model enabler.
Because LTE is an all-IP network, EPC must support a diverse mix of services, with variable real-time and best-effort traffic profiles. This requires equipment design and deployment models that balance session management and transaction-rate performance with low-cost packet processing. In terms of design heritage, the EPC equipment draws on the classic, mobile-centric 2G/3G packet-switch core, and on data-centric fixed-line IP platforms, to create a new type of mobile core network that scales both in the control plane and the user plane.
This balance was not easy to deliver in the past, but is now more achievable due to new approaches to system design, advances in processor technology and progress in operating system and middleware design. For operators, EPC deployment represents a major capital investment and because the EPC interacts directly with so many other parts of the network, the definition of a target architecture, and selection of vendor equipment, will absorb intellectual resources in network design and operating teams over a long period. This makes it a strategic, high-risk project with a high cost of failure, but also a project that demands innovation.
Given the need to innovate in EPC, combined with the need to manage risk and complexity, vendor selection is critical. This means not only are product capabilities and roadmaps important, but also, because operators make core network decisions of this magnitude infrequently, the integration and best-practice expertise accumulated by vendors is invaluable.
Evolved Packet Core Market Forecast & Competitive Analysis reviews trends in the mobile packet core equipment market, analyzes the critical factors that operators need to consider when evaluating and deploying EPC and discusses the evolution to an EPC-based common core for multiple access networks. It also considers the various EPC deployment options, including distributed versus centralized models and how the target architecture impacts advanced services, such as VoLTE and cloud.
The report also identifies and evaluates vendor approaches to EPC product design and deployment architectures, and provides a detailed competitive analysis of the portfolios of seven leading EPC equipment vendors.
The key factors operators must consider when investing in EPC can be summarized as follows:
The market for mobile packet core equipment has grown strongly for the past five years, driven by the growth in smartphone users and demand for capacity. Many operators have refreshed their core networks to manage the ramp-up in 3G/HSPA services. More recently, LTE has meant operators have needed to invest in new EPC platforms. We estimate the mobile packet core market was worth $1.9 billion in 2011 and will increase to $2.5 billion by 2015, as shown in the excerpt below.
