eCNS600 Core Network

The Enterprise Core Network System 600 (eCNS600) is developed by Huawei for the enterprise Evolved Packet Core (EPC), and it applies only to the Long Term Evolution (LTE)/System Architecture Evolution (SAE) architecture. It integrates the subscriber management functions of the SAE-HSS, the Mobility Management Entity (MME) functions, and the Serving Gateway (S-GW)/PDN Gateway (P-GW) and Policy and Charging Rules Function (PCRF) functions. The eCNS600 is operated and maintained in a centralized manner.

High Integration

The eCNS600 integrates the authentication management functions of the SAE-HSS, the MME functions, and the S-GW/P-GW functions. Installed in a basic subrack, the eCNS600 implements the EPC functions and has the following features:

  • Large capacity
  • Supports 200,000 UEs and large-size data transmission
  • Integrates multiple logical NEs of the EPC, simplifies the network and maintenance, reduces costs, and allows easy deployment.
  • Low power consumption
  • Reduces maintenance costs because the power consumption is 900 W for an eCNS600 deployed in single-board mode

Advanced ATCA Platform

  • ATCA is a hardware standard. It is the name of the architecture standard for the hardware platform rather than the name of a specific product.
  • The eCNS600 uses the Open Standards Telecom Architecture (OSTA 2.0) platform of Huawei, which is a server system featuring high density and high performance based on the ATCA standard architecture. The eCNS600 can provide reliable data processing services for carrier-grade telecommunications applications:
  • High rate:the data exchange bandwidth intra-subrack can reach 2.5 Tbit/s.
  • High reliability:the reliability of the system reaches 99.999%.
  • High scalability:supports the addition of the interfaces on the ATCA board and cascading between subracks
  • Easy to upgrade
  • Efficient management: can manage any part in the system.

High Reliability

  • Backup of important data:the reliability of the system reaches 99.999%.
  • Operation security managemen:Different management privileges are assigned to different users. During the user login, the eCNS600 checks the user identity.
  • Hardware redundancy design
  • Fault prevention
  • The eCNS600 provides protection mechanisms to avoid the following system faults:
  • System power off
  • Misoperation on the system power switch
  • Lightning surge on the system power
  • High voltage and low voltage
  • Short circuit of power supply
  • Current surge and high voltage on the power supply and interfaces
  • System overload control
  • Board lock and unlock, process lock and unlock
