10 3 Application and Installation Scenarios 3 Application and Installation Scenarios 3.1 Application Scenarios The BTS3902E works well for covering hot spots and reducing blind spots. Insufficient network capacity in hot spots and blind spots greatly affect user experience. With its flexible deployment, the low-cost BTS3902E helps operators solve these problems. Figure 3-1 shows application scenarios for the BTS3902E. Figure 3-1 Application scenarios 7

11 3 Application and Installation Scenarios 3.2 Installation Scenarios The BTS3902E is ideal in outdoor installation scenarios. It can be installed on a wall, pole, or L-shaped rack. The typical installation scenarios are shown in Figure 3-2. Figure 3-2 Installation scenarios 8

12 4 Operation and Maintenance 4 Operation and Maintenance BTS3902E operation and maintenance (O&M) covers management, monitoring, and maintenance of the software, hardware, and configuration of BTS3902Es. In addition, BTS3902Es allow diversified O&M modes in different scenarios. 4.1 Operation and Maintenance Modes The BTS3902Es support near-end, far-end, and local Ethernet service port operation and maintenance (O&M). In near-end O&M mode, maintenance personnel log in the local maintenance terminal (LMT) through a local Ethernet maintenance port to maintain BTS3902Es. In far-end O&M mode, maintenance personnel centrally maintain BTS3902Es on the U2000 or LMT in the radio network controller (RNC) equipment room or operation and maintenance center (OMC). In local Ethernet service port maintenance mode, maintenance personnel maintain a BTS3902E under the same RNC as the current BTS3902E through a local Ethernet service port on the LMT. The IP route between the current BTS3902E and the other BTS3902E is established by the RNC. Figure 4-1 shows the O&M system of BTS3902Es. 9

13 4 Operation and Maintenance Figure 4-1 O&M system of BTS3902E The O&M system of BTS3902Es consists of the following elements: LMT: is mainly used to locally or remotely maintain BTS3902Es and configure data. BTS3902E: is the O&M object. U2000: short for imanager U2000 Mobile Element Management System, which centrally manages Huawei network devices; the U2000 also remotely and centrally manages multiple base stations. CME: short for Configuration Management Express, which can configures and manages data for multiple base stations. BTS3902E O&M modes have the following features: Supports the Dynamic Host Configuration Protocol (DHCP) and Adaptive and Active Cache Pool (AACP). When no data is configured for the system or when the system is faulty, the O&M channel can be automatically set up. This enhances the system reliability and facilitates remote troubleshooting. Supports configuration baseline, simplifying the configuration rollback process and improving configuration rollback reliability. Provides a comprehensive system self-check function, omitting local software commissioning. 4.2 Operation and Maintenance Functions The OM subsystem of the BTS3902E provides functions such as commissioning management, equipment management, software management, alarm management, security management, and environment monitoring Commissioning Management Commissioning management provides the following functions: Equipment performance tests, such as CPU usage test, clock source quality test, and power test Service performance tests, such as uplink channel scanning and statistics for service resource usage 10

14 4 Operation and Maintenance Equipment Management Equipment management consists of equipment maintenance and data configuration. Equipment management has the following functions: Equipment maintenance includes the maintenance of equipment, for example, managing the status of equipment, performing self-check on the equipment, and calibrating the clock. Data configuration includes configuration, query, and backup of equipment parameters, for example, configuring the parameters of the NodeB hardware, parameters of the NodeB clock, algorithm parameters, and RF parameters Software Management Software management provides the following functions: Activating the software Checking the compatibility of software and hardware versions Managing versions, for example, querying hardware and software versions Upgrading the software version, cold patch, and hot patch Alarm Management Alarm management involves equipment alarm management and environment alarm management. Equipment alarm management The alarm management system detects and reports information about faults in real time. The LMT or U2000 then displays the alarm information and provides appropriate handling suggestions. The alarm management system of the U2000 connects to an alarm box through a serial port and supports audible and visual alarms through the LEDs or the alarm box. The maintenance personnel can subscribe to specific alarms. When related alarms are generated, the alarm information is forwarded to the handsets or pagers of the maintenance personnel so that they can rectify the faults in time. Environment alarm management Generally, equipment rooms of NodeBs are unattended and distributed over a large area. The equipment works in a relatively adverse environment, and emergency cases may incur. To help you handle such emergencies, the BTS3902E provides a complete alarm management system. Alarm management provides the following functions: Alarm detecting Alarm reporting Alarm shielding Alarm acknowledging Alarm pre-processing Alarm correlation processing Alarm help processing 11

15 4 Operation and Maintenance Security Management The operation rights of maintenance personnel are classified into multiple levels when both NodeB and U2000 are applied. This ensures that the running equipment is free from misoperations Environment Monitoring The environment monitoring system provides customized solutions regarding door control, infrared, smoke, water immersion, humidity, and temperature. 12
