RRU 3829 RRU Functions The RRU performs the following functions:  Receives downlink baseband data from the BBU and sends uplink baseband data to the BBU. Receives RF signals from the antenna system, down-converts the signals to intermediate frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital conversion. The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion, and up-converts RF signals to the TX band.  Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals. The RRU can be powered by the AC/DC power module. The RRU is called AC RRU..

Alarm Check and Fault management of eNodeB This section describes the basic concepts related to fault, event, and engineering alarms

Fault Alarm A fault alarm is generated when a hardware is faulty or a major function is abnormal. A fault alarm has a higher severity than an event. Based on the status of the faults, fault alarms can be categorized into active alarms and cleared alarms. If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is called a cleared alarm. If a fault is not cleared, the status of the alarm remains active. This type of alarm is called an active alarm.

Event Alarm An event notifies users of important information when the system is running properly. Users need not handle an event when it is generated.

Engineering Alarm If an NE is being installed, commissioned, upgraded, expanded, or relocated, the NE is in the engineering state. The following are engineering alarms: alarms reported by physical or logical equipment in the engineering state; alarms that are generated by the peer equipment but are associated with the alarms reported by the equipment in the engineering state; cleared alarms corresponding to engineering alarms. HUAWEI TECHNOLOGIES CO., LTD.

Huawei Confidential

Page 65

Alarm Severity The alarm severity indicates the severity of an alarm. Based on the severity, all alarms can be categorized into four types: critical, major, minor, and warning. Severity

Definition

Handling Suggestion

Critical

Service-affecting condition. Critical alarms require immediate Alarms must be cleared immediately. Otherwise, the attention, and must be cleared immediately. For example, faulty system may break down. devices are repaired or unavailable resources are restored.

Major

Degradation of service, not a complete loss of service. Major alarms must be cleared during working hours. For example, device performance and resource performance improve.

Minor

Non-service-affecting condition. Minor alarms must be handled This helps maintenance personnel identify and clear within a certain period to avoid severer problems. potential problems in time.

Warning

Potential service-affecting condition. Warning alarms must be cleared as required.


These alarms must be cleared in time. Otherwise, some important functions cannot be implemented.

You only need to learn about the operating status of the system.

Huawei Confidential

Page 66

NM Alarm Type Based on network management (NM) standards, alarms are categorized as follows: Power alarm: related to the power system Environment alarm: related to environment of the equipment room Signaling alarm: related to service signaling Trunk alarm: related to the transport subsystem Hardware alarm: related to boards Software alarm: related to software Running alarm: related to system running Communication alarm: related to the communication system Integrity violation alarm: a type of security alarm, which indicates that information may be modified, added, or removed without permission. Operation violation alarm: a type of security alarm, which indicates that services are unavailable or unreachable due to incorrect operations, faults, or other reasons. Physical violation alarm: a type of security alarm, which indicates that physical resources are unavailable due to possible attacks. Security violation alarm: a type of security alarm, which indicates that the security service or security mechanism detects that the system is experiencing attacks. Time domain violation alarm: a type of security alarm, which indicates that unexpected events have occurred. Processing error alarm: related to other exceptions. HUAWEI TECHNOLOGIES CO., LTD.
