ZTE provides an integrated core network gateway product, ZXUN xGW (extendable Gateway). It supports 2G, 3G, LTE and non-3GPP access. ZXUN xGW could be deployed as a PDSN, GGSN, SAE-GW, HA and combo function node to satisfy different scenarios during the evolution to pure LTE/EPC network.

Features
- High-performance Based on ZTE Broadband Convergence Platform
Build on broadband convergence packet gateway, featured with large capacity, high performance and high integration. One cabinet in full configuration supports 160Gbps throughput and 24Million PDP.
- TelecomClassHighAvailability
Every hardware unit with redundancy design, every unit supports hot swapping.
Support NSR and online patching and function upgrading.
Geographical redundancy capability provides reliable communication even when one site is out of service.
Multi-level disaster recovery mechanism guarantees that network reliability easily reaches 99.999%.
- Precise Traffic Management Based on Subscriber and Service
Based on 3GPP PCC architecture, provides dynamic charging and policy control for enforcing of access control, QoS management, routing policy and charging policy control based on service, subscriber, network type etc for the operator.
DPI interworking with ZXUN UBAS (user behavior analysis system) product provides service, subscriber and network information reporting and analysis as tools for user behavior analysis, service development analysis and network optimization.
- Green Technologies
High integration saves average power consumption, equipment room space and conforms to the trend of sustainable developing of green network.
Intelligent processing board power control based on system load to reduce power consumption during idle time
Smart fan speed control according to system temperature to save power consumption
- Access Agnostic
Supporting GGSN/ PDSN/ HA/ SAE-GW… in one system, convergent Gateway benefits the operator with TCO saving for multi network co-existence, seamless mobility and migration to future network with software upgrading only.
Capability for BRAS /ePDG /WAG provides fixed and mobile convergence.
- IPv6 Ready
Support IPv4v6 dual stack, IPv4 in IPv6, IPv6 in IPv4 and IP application protocols as DHCPv6, DNS client v6, Radius to solve the shortage of IPv4.
