maintenance knowledge, basic operation skills, and emergency handling skills of thedevices. You must also strictly follow the operation rules and industrial safety rules toensure personnel safety and device safety.

1.2.2 Requirements for the Running EnvironmentThis topic describes the requirements on the running environment.The aspects equipment room, power supply system, air conditioning system, lighting system,fire prevention, and storage conditions need to meet the requirements on the runningenvironment.

Physical Environmentl The temperature ranges from 15C to 25C. The recommended temperature is 20C 2

C. The hourly temperature variation is less than 3C.l The relative humidity ranges from 40% to 70%. The hourly relative humidity variation is

less than 3%.l A high-voltage static air cleaner is a recommended device in the minicomputer room.l Do not put the articles such as user manuals, software application manuals, report paper

and ribbons in the minicomputer room.

Power Supply Systeml The power supply of the equipment must be exported directly from the main distribution

panel of a factory or a building (independent special power supply). In addition, the powersupply cannot be shared by devices irrelevant to the system, such as lighting devices orduplicating machines.

l The AC power supply regulator should be installed to filter out surge and interference, thusproviding the equipment in the minicomputer room with pure and stable power supply.

l An uninterruptible power supply (UPS) is required to avoid data loss and device damagein case of power failure.

l If the 110 V and 220 V AC sockets are both provided, they must be clearly labeled.l The positions of the power supply cables and sockets must be clearly marked in the switch

board for reference in future troubleshooting or expansion.l Outlets for signal cables/power cables must be left on the raised floor and the edge of the

outlets must be covered with the rubber pad to protect the power and signal cable.l The inlets through which the signal cable power cables are led into the computer room must

be tightly sealed to prevent dirt, rats, and insects from getting in. If the equipment room isdivided into minicomputer room and operation room, the conduit line must be reserved inthe partition wall to avoid leading the signal cable through the wall. The conduit may adoptPVC tube with a diameter of over 6 cm.



1-3

Air Conditioning System, Lighting System, and Fire Preventionl To meet the requirements of the equipment for running time and room cleanness, an

independent air condition system must be adopted for the computer room, but central airconditioning system must be avoided whenever possible.

l The minicomputer room and the operation room must be installed with emergent lightingwith backup power of maintenance-free batteries.

l The minicomputer room should be equipped with automatic fire alarm according to relatedfire fighting regulations for buildings, but automatic sprinklers are strictly prohibited.

l Fire extinguishing devices in the minicomputer room must be applicable to electrical andcommunication devices. Common fire extinguishers such as sprinkler system are notrecommended.

l The operation personnel must have training on fire control knowledge, and they must checkthe fire control device periodically.

StorageAll the components not yet installed must be stored in a suitable storage space.l Equipment: All equipment must be packed properly.l Temperature: 15C to 25C. The hourly temperature variation is less than 10C.l Relative humidity: 30% to 80%.l The air purity must meet the requirements listed in Table 1-1.

Table 1-1 Parameters of air purityParticle Diameter (m) Allowed Number of Particles

(ppm) 1 4 x 107 1.5 4 x 106 5 4 x 105The content of sulfur dioxide cannot exceed 0.14 ppm.

1.2.3 Requirements for Security ManagementThis topic describes the requirements of security management.

Network Securityl The personnel that have no rights are prohibited from touching equipment.l Avoid using terminals on the LAN to access Internet or play games, so as to avoid illegal

access and viruses.l Avoid portable computers to connect to the LAN.




Issue 01 (2010-09-29)

System Securityl Strictly control the enabling of the network services.l The connection status of the network is routinely monitored to ensure that an access to the

network is authorized.l Passwords of users must be changed periodically, and rights must be strictly controlled for

proper tasks.

Data SecurityThe backup plan must be carried out strictly to back up the system data periodically.

1.2.4 Requirements for Equipment DocumentsThis topic describes the requirements of equipment documents.Equipment documents have the following types:l Product documents

Engineering documents of network Engineering documents of device Engineering documents of upgrade Networking diagram Equipment room layout Specifications of special software

l Technical documents, user documents, and maintenance documents delivered withequipment. The completion of equipment documents must be ensured. In addition, filesmust be updated in time along with device configuration and networking changes so as toguide the maintenance more effectively.

l The previous routine maintenance tables for comparison must be ensured, so as to checkcertain performance data, such as CPU, memory usage.

2 Backup StrategiesAbout This Chapter

The important data or files in the CBS system need to be backed up periodically so that they canbe restored if necessary. This chapter describes the backup strategies of the core NEs andneighboring NEs of the CBS system, including the backup strategies of operating systems,databases, applications, logs, configuration files, and CDRs. Each backup strategy covers theinformation such as the backup frequency, storage medium, and the contents to be backed up.2.1 Usage InstructionService engineers need to read the backup strategies before performing backup operations toobtain the information such as backup frequency, storage medium, and backup contents.2.2 Backup Strategy TableThe backup strategy table contains the backup strategies of operating systems, databases,applications, configuration files, logs, and CDRs.

2.1 Usage InstructionService engineers need to read the backup strategies before performing backup operations toobtain the information such as backup frequency, storage medium, and backup contents.

Usage Instruction of Backup StrategiesIt is recommended that service engineers refer to the backup strategies and perform backup tasksaccording to the following instruction:

Figure 2-1 Usage Instruction of Backup Strategies

Maintenance engineers need to understand the backup policy, including the information such asthe backup frequency, backup contents, and backup medium. In addition, maintenance engineersneed to understand the specific backup methods. For details about the backup policy, see 2.2Backup Strategy Table. The backup methods are described in different maintenance cyclechapters according to the backup frequency. The following is an example:

Example[Example 1- Find Backup Task According to Backup Frequency] Backing up the database

2 Backup StrategiesHUAWEI CBS



Issue 01 (2010-09-29)

1. Find the table named "Backup strategy: databases." Read the backup strategies for thedatabase of the XX NE to understand the backup contents and the backup frequency "everyday."

2. In the chapter related to daily maintenance, find the section related to backing up thedatabase of the XX NE, and then refer to the backup operation guide in this section.

[Example 2- Find Directly] Backing up the BMP operating system1. Assume that the on-site BMP uses the ATAE server. full-text search the section related to

backing up the SuSE operating system , and then refer to the backup operation guide in thissection.

2. Maintenance engineers need to know about the backup medium and frequency accordingto the table "Backup strategy: operating systems."

2.2 Backup Strategy TableThe backup strategy table contains the backup strategies of operating systems, databases,applications, configuration files, logs, and CDRs.

NOTE

The values described in this section are recommended values in normal cases. You can change them asrequired. For example, the backup frequency relates to the number of subscribers of an office, so you needto change the backup frequency according to the number of subscribers of this office. Generally, the greaterthe number of subscriber is, the more frequent the data needs to be backed up.

Special description:l Backup retention duration: If no special description is provided, the default retention

duration is to retain the backup files until the next backup is successful.l Backup retention quantity: If no special description is provided, the default retention

quantity for database files is at least two copies. For backup of other data, at least one copyof backup files is required.

l Backup level: If no special description is provided, the full backup is required for thedatabase backup.

l Active and standby nodes: If no special description is provided, all backup contents needto be backed up on both the active and standby nodes.

ExampleNone.

Exception HandlingIf performance monitoring tasks are created, the maintenance engineers receive alarm messageswhen the performance index is abnormal. Then, they can solve the problem in time. To knowhow to process alarms on the I2000, see 3.1 I2000 Alarm Handling.

3.3 Monitoring the CBS Through the SMAPThe monitoring system monitors the running status of an NE such as the CBP, Billing, AR, andDC, monitors the service handling statuses through the Invoicing function, and displays theservice handling statuses in histogram, curve, or pie chart, which helps users to learn about theservice running statuses in time.

Prerequisitel Each NE in the system is connected normally.l The NE data collected by the system is written into the OM central database.

ContextThe monitoring interface focuses on the application running status and load status. Themonitoring interface consists of two layers of view.l The first-layer view is called monitoring layer 0. It collects the status data of each NE in

the system and displays the real-time running status of the entire system.l The second-layer view is called monitoring layer 1. It displays the service running status

of an NE and current data of each node.Table 3-2 describes the detailed alarm information on an NE on the monitoring layer 0.

Exception HandlingMaintenance engineers can handle an alarm or error according to the following thoughts whenfinding the alarm or error prompt on the monitoring interface:Handle a CAPS alarm according to the exception handling of the Evaluating the Traffic onthe SCP.Handle an error CDR according to the exception handling of the Checking the Offline CDRon the CBP.When the bill run data generated by the Billing is incorrect, exception information is recordedin the corresponding task log. Maintenance engineers can rectify the exception according to theexception information. To rectify the exception, do as follows:1. Log in to the Billing.2. Enable the log function by running setval -l debug.



3-9

3. Access the log path ${HOME}/log/debug/bmp_debug.log.When the deregistration data generated by the AR is incorrect, exception information is recordedin the corresponding task log. Maintenance engineers can rectify the exception according to theexception information. To rectify the exception, do as follows:1. Log in to the server where the AR is located.2. Enable the log function by running setval -l debug.3. Access the log path ${HOME}/log/debug/bmp_debug.log.If an error occurs when the Invoicing bills are formatted, maintenance engineers need to try toformat the bills again.If other exceptions occur, contact Huawei engineers.

3.4 Reconciling the CBS Through the SMAPThe reconciliation function is mainly used to display reconciliation information between NEssuch as the CBP, Billing, Invoicing, AR, and DC. The running statuses of system services canbe displayed dynamically in real time, helping users to learn about the system running status.

Prerequisitel Each NE in the system is connected normally.l The NE data collected by the system is written into the OM central database.

ContextReconciliation can be classified into the following types according to involved NEs:l Reconciling the number of CDRs between the CBP and the Billing, that is, checking

whether the number of CDRs generated by the CBP is the same as that of the CDRs receivedby the Billing

l Reconciling the number of bills between the Billing and the Invoicing, that is, checkingwhether the number of bills generated by the Billing is the same as that of bills processedby the Invoicing

l Reconciling the number of accounts between the Billing and the AR, that is, checkingwhether the number of accounts on which the Billing performs bill run is the same as thatof accounts deregistered by the AR

l Reconciling the number of transactions between the DC and the AR, that is, checkingwhether the number of transactions performed by the AR is the same as that of thetransactions processed by the DC

l Reconciling the number of transactions between the CBP and the AR, that is, checkingwhether the number of transactions performed by the AR is the same as that of thetransactions received by the CBP

NOTEIn addition to the inter-NE reconciliation function, the CBP has the intra-NE reconciliation function to reconcilethe number of online CDRs. The reconciliation formula is as follows: Number of messages + Number of splitmessages = Number of charging CDRs + Number of error CDRs + Number of CDRs for
