6 Reliabili
ty
Overview
The Horizon 3G-nx Node Bs introduce a new system structure and provide a
complete redundancy design. It also takes advantage of large-capacity ASIC chips to
enhance the integrity of modules, reduce the number of parts and greatly improve the
reliability of the system.
System Reliability
The system reliability of the Horizon 3G-nx Node Bs is embodied in the load-sharing
and redundancy configuration design, which optimizes the fault detection/isolation
technology 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 Node B
all support redundancy. The BBU supports load sharing.
The CPRI port that connects the BBU and the RRU supports ring networking. When
one CPRI link is faulty, the Node B can automatically switch to another CPRI link.
The key data such as software version and data configuration files in the Node B
supports redundancy.
Reliability Design
The Node B can automatically self-detect and diagnose hardware failure and
environment related problems and then report alarms. It also attempts to conduct
self-healing to clear faults. If the self-healing fails, it can automatically isolate the
faults.
Page 50 Total 73
Horizon 3G-nx Node B Solutions
Technical Brief
Hardware Reliability
Board Insertion Failsafe
The backplane and boards have been designed to ensure that when a board is
wrongly inserted into a slot [of another board], the board does not connect to the
backplane and as a result damage does not occur.
Software Reliability
Software reliability includes the redundancy of key files and data and the powerful
error tolerance of software.
Software Redundancy
The Horizon 3G-nx Node Bs provide redundancy for key files and data such as
software versions and data configuration files to prevent them from damage and to
ensure the normal running of the Node Bs.
Redundancy of software versions
The Horizon 3G-nx Node Bs provide separate redundancy for software versions
including the BootROM software version to avoid version problems. If one
version is faulty, the Node B can switch to the backup version.
Redundancy of data configuration files
Page 51 Total 73
Horizon 3G-nx Node B Solutions
Technical Brief
The Horizon 3G-nx Node Bs provide separate redundancy for data configuration
files to avoid interrupting the running of the files. If the current file is faulty, the
backup file can still work properly.
Error Tolerance
Should a software fault develop, it does not affect the entire Node B because the
system is capable of self-healing. The software error tolerance functions are as
follows:
Scheduled detection of key resources
The Horizon 3G-nx Node Bs perform occupancy check on software resources. If
a resource hang-up occurs due to software faults, the Node B can release the
unavailable resources in time and export logs and alarms.
Task monitoring
During the running of software, the Horizon 3G-nx Node Bs monitor the internal
errors of all software and some hardware faults, if any. The Horizon 3G-nx Node
Bs also monitor task progress and running status, report alarms when the system
is faulty and try to restore the task by self-healing.
Data Consistency Check
The Horizon 3G-nx Node Bs perform scheduled or event-triggered data
consistency checks and can restore the data consistency preferably or
preferentially. Additionally the Node Bs generate related logs and alarms.
Dongle
The Horizon 3G-nx Node Bs can detect the irregular running status of the
software and then automatically reset the system through the dongles at both
software and hardware levels.
