UGW

The UGW9811 is a Huawei proprietary unified packet gateway. It is intended for use in the Enhanced 3G (E3G) Long Term Evolution/Evolved Packet Core (LTE/EPC) network. The UGW9811 can function as a GGSN, an S-GW, a P-GW, or any combination of them but can be conveniently managed as a single unified gateway.

Features

The UGW9811 provides the following features:

Support for multiple access modes, including General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), LTE, CDMA2000 High Rate Packet Data (HRPD), and Wi-Fi access.

Industry-leading end-to-end collaboration:

The UGW9811 works in conjunction with the RAN to provide end-to-end (E2E) solutions, such as E2E QoS guarantees and detection of cell congestion.

High reliability design:

  • Hot swap and redundant backup, double power supplies, and overvoltage/overcurrent protection for key boards
  • Overload control, flow control, resource check, self fault detection, system software backup, and configuration consistency check for stable and reliable system operation
  • CDR cache function for charging reliability
  • Hot patch technique for software operation reliability
  • Route backup and route-based load balancing for preventing single-point failures and ensuring high network reliability

High security guarantee

  • Strict operator identity check
  • Multiple authentication modes, including Point-to-Point Protocol (PPP), Password Authentication Protocol (PAP), and Challenge Handshake Authentication Protocol (CHAP)
  • Packet filtering and access control list (ACL) to filter packets based on specified conditions
  • Gi interface redirection to prevent packet attacks between mobile subscribers on the same UGW9811
  • Support for IPSec, which provides IP packets with high-quality, interoperable, and cryptology-based security

Applications and Benefits

By integrating the functions of the GGSN, S-GW, P-GW, trusted gateway (TGW), evolved packet data gateway (ePDG), HRPD serving gateway (HSGW), and packet data serving node (PDSN), the Huawei UGW9811 helps reduce operating expense (OPEX) and improves network deployment capabilities. These NE functions can be deployed on one or on multiple UGW9811s. When these NE functions are deployed on a single UGW9811, they share the UGW9811's hardware, cutting down UGW9811 deployment costs.

Key Features Introduction

Smart Bandwidth Management

The Smart Bandwidth Management solution properly utilizes network resources and maximizes returns for carriers from their investments by enhancing user experience. It also provides carriers with business models that create more value, improving their comprehensive competitiveness.

Customer Requirements Overview of the Solution and Its Advantages

In the content-oriented mobile Internet era, carriers are faced with the challenges of improper use of network resources and separation of investments and returns. How to effectively use network resources, ensure user experience, create new business models, and build a favorable business environment.

Overview of the Solution and Its Advantages

In addition to GPRS and UMTS access management, Smart Bandwidth Management provides strong LTE/EPC network management and non-3GPP access (such as CDMA, WiMAX, and Wi-Fi access) capabilities, as well as support for fixed mobile convergence (FMC). This solution has the following advantages

High Reliability and High Performance

Network elements (NEs) in the control domain use the Advanced Telecom Computing Architecture (ATCA) platform that has excellent computing performance. The ATCA platform ensures better performance and higher reliability for the SGSN9810 and USN9810. The gateway domain uses the packet gateway platform (PGP) that provides router functions. This ensures excellent performance of the GGSN9811 and UGW9811 in terms of throughput, forwarding, and reliability.< /p>

Diversified Value-added Services

Based on the standardized policy and charging control (PCC) system architecture, this solution provides flexible bandwidth control policies and rules. This solution provides over 12 bandwidth control methods based on the application type, user class, quota, terminal type, location, and time. For example, it provides the fair usage policy (FUP), VIP treatment, and low-value service management.

Applications and Benefits

Smart Bandwidth Management has been commercially deployed at over 60 sites worldwide. It helps carriers develop new business models, enhance their network competitiveness and manageability, and improve user experience. With this solution, carriers' comprehensive competitiveness is significantly enhanced.
