The USN9810 is our proprietary unified serving node. It can be used in the 2.5G General Packet Radio Service (GPRS) system, 3G Universal Mobile Telecommunications System (UMTS), and evolved packet core (EPC) system.
The USN9810 integrates the serving GPRS support node (SGSN) and the mobility management entity (MME). It can provide functions of the SGSN, MME, or both, and is maintained using the same operation and maintenance system (OMS) regardless of the provided functions.
The USN9810 uses a high-speed forwarding processor to forward data on the user plane, which improves the processing efficiency and system integration.
The USN9810 uses the Open Standard Telecom Architecture (OSTA2.0) hardware platform, which is a server system featuring high density and high performance. The OSTA2.0 hardware platform enables the USN9810 to provide reliable data processing services for carrier-class telecommunications applications. A series of specifications related to boards, backplanes, and software for the next generation telecom devices are stipulated based on the OSTA2.0 hardware platform. The OSTA2.0 hardware platform is developed based on the ATCA standard architecture and conforms to the network equipment building system (NEBS) and European Telecommunications Standards Institute (ETSI) standards.
The USN9810 automatically backs up important data, such as configuration data, performance data, and operation logs.
The USN9810 assigns different permission levels to different users and provides strict identity verification mechanisms. It also records operation details of users in operation logs, ensuring system security.
All critical boards are configured to work in 1+1 backup mode to ensure high reliability of the system.
The USN9810 can protect the system if any of the following exceptions occurs:
If CPU overload or resource congestion occurs, the USN9810 adjusts the traffic properly to prevent system breakdown.
If necessary, board processes and ongoing services can be gradually ended to avoid abrupt service interruption.
The flexible networking helps reduce the operational expenditure (OPEX) of operators.
The high reliability helps operators easily cope with peak traffic.
The Smartphone Optimization solution identifies smartphones, optimizes the signaling behavior, ensures network security, and provides a platform with high performance and large capacity, helping operators minimize the impact of signaling storms.
For the past several years, due to the increasingly popular use of smartphones such as iPhone, Blackberry, and HTC, MBB traffic has increased sharply. However, smartphones' signaling behavior differs from that of feature phones, and brings the following challenges to operators:
An entire end-to-end solution is required to solve the challenges of traffic increase and signaling storms brought by the increased number of smartphones. As an end-to-end solution, our Smartphone Optimization solution provides a variety of measures, including identifying smartphones, optimizing smartphone signaling behavior, and constructing high-performance product architecture. The advantages of this solution are as follows:
High reliability is ensured by the protection mechanism against abnormalities. This protection mechanism can relieve smartphones' signaling impacts on the system in case of a signaling failure on a single node such as the authentication, authorization and accounting (AAA), dynamic host configuration protocol (DHCP), or online charging system (OCS) server. Therefore, the system is protected from breakdown due to single points of failure (SPOFs).
The system can identify smartphone types and ensure end-to-end quality of service (QoS) for VIP subscribers.
The Smartphone Optimization solution identifies smartphones, optimizes the signaling behavior, ensures network security, and provides a platform with high performance and large capacity, helping operators minimize the impact of signaling storms. The smartphone identification and signaling optimization functions help operators better understand the communications behavior of their subscribers and conditions of their networks, reduce the abnormal signaling load, and take precautions for the future network development.
