Position: ZTE Evolved Packet System
ZTE is the only CN vendor supports all radio access technologies in the industry, the products include GSM/UMTS/TD-SCDMA/CDMA/WiMAX/LTE/NGN/IMS, it owns more than 16 years of CN R&D; It has joined more than 50 standard organizations and submitted over 3000 international proposals, which is competent to help operators to realize evolution to the future network.
ZTE puts forward 
concept: C-Convergence, O-Open, R-Reliability, E-Efficiency, and tries to help operators to build an evolvable, reliable and green network with quick response.
ZTE packet core features multimedia express, seamless convergence, embedded intelligence and deep green, which brings simple and easy life to everyone.
● Multimedia Express
Mobile broadband with multimedia services is the trend in telecom industry. ZTE packet core is the express to carry ever-increasing multimedia traffic.
- Large capacity and high performance
- Direct Tunnel
Flat network with low latency is a step forward to LTE/SAE
- MBMS
Complete MBMS features boost the spreading of broadband streaming service
- All IP networking and perfect QoS guarantee mechanism
Gb/Iu over IP, single IP backbone for all interfaces, Diff-Serv and rich QoS control features improve user experience and satisfaction.
- High Reliability
Internal and network level redundancy mechanism eliminate single point failure, SGSN pool and GGSN pool provide double protection for network reliability.
● Seamless Convergence
ZTE converged packet core is compatible for different radio access technologies and realizes seamless service continuity and smooth evolution.
- Mature 2G/3G dual-access solution
Dynamic resource allocation according to 2G and 3G capacities, 2G subs migrates to 3G causes no impact.
- High integrated nodes for both LTE/SAE and legacy networks
Flexible combination and configuration of different functionalities enabled by ZTE uMAC and xGW:
Config options of uMAC : MME, SGSN, MME+SGSN
Config options of xGW : SAE-GW, GGSN, PDSN, AGW, GGSN+SAE-GW…
Unified platform protects operator investment and ensures easy upgrade to evolved core.
- Optimized 2G/3G and LTE handover
Converged core speeds handover between 2G/3G and LTE
- Non-3GPP access capability
Converged core provides non-3GPP radio access and facilitates seamless mobility across different wireless networks.
● Embedded Intelligence
ZTE intelligent packet core provides finer management on charging and services according to 3GPP defined PCC (Policy and Charging Control) architecture. It helps operator regaining the leading role in the mobile service value chain and saves network from becoming a dummy data pipe.
- Deep Packet Inspect for service awareness lays the foundation of charging and service control
Inspection on IP flows from L3 to L7 to identify various services including P2P service.
Content Based Charging, QoS and service control etc. are easily implemented according to operator requirements.
- Wire-speed packet forwarding by dedicated hardware
Multi-core Network processor implements embedded DPI function and wire-speed forwarding.
- Open interfaces for easy networking.
Open Gx, Gy interfaces are provided to PCRF and OCS, Policy and Charging Control functions and Online Charging are easily implemented.
- Quick customization for operators’ specific requirements
ZTE intelligent packet core has rapidly and successfully launched for the largest HK mobile operator-Telstra CSL.
● Deep Green
ZTE adheres to green and sustainable development. It establishes ISO14001 environmental management system and complies with RoHS.
- Intelligent power management
Intelligent board saves power by self-adjusting to traffic statistics, less consumption and emission in idle mode, harmful side-effect is reduced.
- Compact product design
High integration and compact size save equipment room space and conform to the trend of sustainable developing of green network.
- Comprehensive environmental protection
Uniform all-IP platform extends product life cycle for convenient expansion and evolution.
Green material and full consideration of environment friendly recycling technology.
