2 Introduction to OMU

2About This Chapter

Introduction to OMU

The physical entity of the OMU is the OMUa/OMUb/OMUc board. The OMU collects and processes the information about operation and maintenance (OM), and then reports the information to the OM terminal: LMT or M2000. 2.1 Position of the OMU in the BSC6900 This section describes the components of the BSC6900 OM subsystem and the position of the OMU in the OM subsystem. 2.2 OMUa and OMUb Board OMUa refers to Operation and Maintenance Unit REV:a. OMUb refers to Operation and Maintenance Unit REV:b. One or two OMUa/OMUb boards must be configured in the BSC6900. The width of the OMUa/OMUb board is twice the width of other boards. Therefore, one OMUa/OMUb board occupies two slots. The board can be installed in slots 0 to 3, slots 20 to 23, or slots 24 to 27 in the MPS at the bottom of the MPR. The OMUa/OMUb board can be installed in slots 20 to 23 in inventory sites and in slots 24 to 27 in new sites. 2.3 OMUc Board OMUc refers to Operation and Maintenance Unit REV:c. A pair of active/standby OMUc boards must be configured. The OMUc boards can be installed in slots 0 to 3, slots 20 to 23, or slots 24 to 27 in the MPS at the bottom of the MPR.

Figure 2-13 OMU Application Structure

NOTE

The bidirectional arrows shown in Figure 2-13 denote communication between modules.

For details about the OMU service processes, see 2.5.3 OMU Service Processes. For details about the service monitoring entities, see 2.5.2 OMU Service Monitoring Entities.

2.5.2 OMU Service Monitoring EntitiesThe OMU applications perform monitoring at two levels: level 1 and level 2. Level 1 is the system-level monitoring, that is, the omud monitors the monitor. Level 2 is the application-level monitoring, that is, the monitor monitors the service processes. When a service process or the monitor is faulty, the two-level monitoring ensures that the faulty service process or monitor can be restarted.

omudAs a service entity, the omud is registered in the operating system and automatically starts when the operating system starts. The monitor is started when the omud starts and the omud monitors the monitor.

monitorThe monitor manages the OMU boards and monitors the service processes in real time.

2.5.3 OMU Service ProcessesThe OMU provides the back administration function with the help of OMU service processes. The service processes of the OMU are as follows: communication module (ems_gate), authentication module (authority), network management agent module (ems_agent), configuration module (configure), maintenance module (maintain), alarm module (alarm), performance module (stat), software management module (software), OMU management module (omu_manager), time server (sntp), FTP module (ftp_server), exchange module (host_gate), fault diagnose module (cfa), base station maintenance module (btsom), OMU log management module (debug_log), and LMT module (weblmt).

Communication Module (ems_gate)The communication module performs the following functions: Receiving messages from the Element Management System (EMS)/Local Maintenance Terminal (LMT), converting the messages into frames for internal communication in the OMU, and then sending the messages to the authentication module. Receiving messages from the OMU modules, interpreting the messages, and then sending the messages to the EMS or LMT.

Authentication Module (authority)The authentication module performs functions such as authority management, log management, and command resolution.

Network Agent Module (ems_agent)The network agent module performs the following functions: l l Batch command processing Scheduled task management

Configuration Module (configure)The configuration module performs the functions of data configuration and management for the BSC6900 host, such as configuring data effective and ineffective modes, formatting the data files loaded by the host, and checking data consistency.

Maintenance Module (maintain)The maintenance module enables the OMU to query the operating status of objects such as the BSC6900 host hardware, physical/logical links, and channels. It also enables the BAM to test and maintain objects.Issue 08 (2012-02-27) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 32



Alarm Module (alarm)The alarm module handles the alarms. It controls the output mode and classification of alarms, and shields alarms.

Performance Module (stat)The performance module collects, stores, computes the performance measurement data of the host, and then reports the data to the M2000.

Software Management Module (software)The software management module performs functions such as BOOTP service for the OMUa board, OMU software management, OMU active/standby workspace management, file synchronization between the active OMU and the standby OMU, version upgrade management.

OMU Management Module (omu_manager)The OMU management module monitors the OMU hardware and software.

Time Server Module (sntp)The time server module performs the following functions: l l The time server provides time for BSC6900 boards and the BTS. The time client synchronizes with the upper-level time server, and provides the standard time on the upper-level time server for the OMU.

FTP Module (ftp_server)The FTP module serves as an FTP server, and provides file transmission function for the host boards, LMT, and EMS.

Exchange Module (host_gate)The exchange module supports the communication between the OMU service processes and the host.

Base Station Maintenance Module (btsom)The base station maintenance module performs the functions of alarm management, performance management, software management, and routine maintenance for the base station.

Fault Diagnose Module (cfa)The fault diagnose module performs the end-to-end functions of collecting link fault information, periodically diagnosing faulty nodes, and performing self-healing on faults.

OMU Log Management Module (debug_log)The OMU log management module performs the functions of regularly collecting and cleaning up OMU logs.Issue 08 (2012-02-27) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 33



LMT Module (weblmt)The LMT module traces messages, monitors performances, and maintains devices. It also provides an interface for issuing MML commands. Each process is logically independent, that is, when one process fails, other processes continue to run normally. When a process stops unexpectedly, the OMU detects it in time and restarts the process quickly.

2.6 OMU Working ModeThe OMU works in single-OMU or dual-OMU mode.

Single-OMU ModeWhen the BSC6900 is configured with one OMUa/OMUb/OMUc board, it works in singleOMU mode. If the OMU is faulty, you cannot perform OM on the BSC6900. Therefore, the system is unreliable when the OMU works in single-OMU mode.NOTE

The GBAM works in only single-GBAM mode. That is, a BSC is configured with only one GBAM.

Dual-OMU ModeWhen the BSC6900 is configured with two OMUa/OMUb/OMUc boards, it works in dual-OMU mode. In dual-OMU mode, the OMUa/OMUb/OMUc board working in active mode is called the active OMUa board, that is, the active OMU; the OMUa/OMUb/OMUc board working in standby mode is called the standby OMUa board, that is, the standby OMU. The active and standby OMU boards must be of the same type. Mixed insertion of OMUc board and OMUa/OMUb board is prohibited. When the BSC6900 is in dual-OMU mode, the OMU can operate properly with high reliability. When a hardware or software fault occurs on the active OMU, the standby OMU is automatically switched over and works in active mode. It continues to provide services for users and the host.NOTE

l Check the OMU working mode before you install the OMU applications. l After the OMU applications are installed, run the DSP OMU command to query the OMU working mode.

2.7 OMU OM MethodsThis section describes several scenarios and methods of the OMU OM.

Scenario 1: Installing the OMU Applications Before Field CommissioningAfter the BSC6900 hardware is installed, the OMU applications should be installed before the OMU commissioning.Issue 08 (2012-02-27) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 34
