6 Reliability6.1 Overview

The 3900 series NodeBs introduce a fresh new NodeB system structure and providesa complete redundancy design. It also takes advantage of Huawei large-capacityASIC chips to enhance the integrity of modules, reduce the number of parts, andgreatly improve the reliability of the system.

6.2 System Reliability

The system reliability of the 3900 series NodeBs is embodied in the load-sharing andredundancy configuration design, which optimizes the fault detection/isolationtechnology of boards and systems and greatly improves the reliability of the system.

Redundancy Design

The main control board, transmission board, power supply unit, and fan in the NodeBall support redundancy. The BBU supports load sharing.

The CPRI port that connects the BBU and the RRU supports ring networking. Whenone CPRI link is faulty, the NodeB can automatically switch to another CPRI link.

The key data such as software version and data configuration files in the NodeBsupports redundancy.

Reliability Design

The NodeB can automatically self-detect and diagnose hardware failure andenvironment problems, and then report alarms. It also attempts to conductself-healing to clear faults. If the self-healing fails, it can automatically isolate the

faults.


44/56



6.3 Hardware Reliability

Anti-Misinsertion Function of Boards

When a board is wrongly inserted into the slot of another board, the mistaken board

cannot be connected to the backplane and in this way the equipment is free fromdamage.

Overtemperature Protection

When the ambient temperature of the power amplifier on the RRU is too high, theNodeB generates overtemperature alarms and immediately switches off the poweramplifier to prevent it from damage.

Power Supply Reliability

Power supply units of the 3900 series NodeBs are also reliable in the followingaspects:

The 3900 series NodeBs have wide-range voltage and surge protectionfunctions.

The 3900 series NodeBs provide power failure protection for programs and data.

The boards protect power supply against overvoltage, overcurrent, and reverseconnection of positive and negative poles.

Hierarchical shutdown

The outdoor NodeB performs shutdown for the PA according to the backup powercapacity.

Surge Protection Reliability

The 3900 series NodeBs take surge protection measures on AC/DC power sockets,input/output signal ports (E1 port, interconnection port, and Boolean alarm port),antenna connectors, and GPS ports.

6.4 Software ReliabilityThe software reliability includes the redundancy of key files and data, and the powerfulerror tolerance of software.

Software Redundancy

The 3900 series NodeBs provide redundancy for key files and data such as software

versions and data configuration files to prevent them from damage and to ensure thenormal running of the NodeBs.

Redundancy of software versions

The 3900 series NodeBs provide separate redundancy for software versionsincluding the BootROM software version to avoid version problems. If one versionis faulty, the NodeB can switch to the backup version.

Redundancy of data configuration files


45/56



The 3900 series NodeBs provide separate redundancy for data configuration filesto avoid interrupting the running of the files. If the current file is faulty, the backupfile can still work properly.

Error Tolerance

When the software is faulty, it does not affect the entire NodeB because the system iscapable of self-healing. The software error tolerance functions are as follows:

Scheduled detection of key resources

The 3900 series NodeBs perform occupancy check on software resources. Ifresource hang-up occurs due to software faults, the NodeB can release theunavailable resources in time and export logs and alarms.

Task monitoring

During the running of software, the 3900 series NodeBs monitor the internalerrors of all software and some hardware faults, if any. The 3900 series NodeBsalso monitor task progress and running status, report alarms when the system isfaulty, and try to restore the task by self-healing.

Data Consistency CheckThe 3900 series NodeBs perform scheduled or event-triggered data consistencycheck and can restore the data consistency preferably or preferentially. Also, theygenerate related logs and alarms.

Dongle

The 3900 series NodeBs can detect the irregular running status of the softwareand then automatically reset the system through the dongles at both software andhardware levels.
