Table 4-2 Usage scenarios and advantages of the four topologies Topology

Usage Scenario

Advantage

Star

A wild range of areas, especially densely populated areas

l Networking is simple. l Engineering is easy. l Maintenance is easy. l Network capacity expansion is easy. l Transmission reliability is high.

Chain

Strip areas that are sparsely populated such as areas along highways and railways

This topology helps reduce expenditure on transmission device, engineering, and leased transmission cables.

Tree

Areas where network architecture, site distribution, and subscriber distribution are complicated such as an area where large-scale coverage overlaps with hot spot areas or small-scale coverage.

Compared with the star topology, this topology requires fewer transmission cables.

Ring

A wild range of areas. Because of its self-healing capability, this topology is recommended when a route is available.

A ring topology can automatically split into two chains if transmission is disrupted at a breakpoint and base stations before and after the breakpoint can still function properly. This improves the system robustness. As shown in Figure 4-3, transmission is disrupted at B. Before disruption, BTSs 0, 1, and 2 are connected in a clockwise direction, forming a ring topology.

Remarks

Chain

The transmission equipment cost is low.

l The number of cascading levels in a chain and the cascading distance are restricted.

l This topology is applicable to scenarios where capacity is large.

l Faults in an upper-level RF module may affect lower-level RF modules.

l RFUs and RRUs cannot be cascaded.

Compared with other topologies, this topology requires large numbers of optical cables.

This topology is applicable to scenarios where capacity is small.

l The number of cascading levels in a chain and the cascading distance are restricted.

l Only RRUs can be used in the ring topology.

Star

l Installation and maintenance are easy. l Transmission reliability is high. When an RF module or optical cable is faulty, only one sector is affected.

Ring

Transmission reliability is guaranteed.

l Faults in an upper-level RRU may affect lowerlevel RRUs.

l The ring topology is implemented by adding a redundant chain to a chain topology.

Based on the distance between a BBU and an RRU, CPRI networking is classified into shortdistance remote networking and long-distance remote networking. l

For the short-distance remote networking, the longest distance between an RRU and a BBU on a CPRI chain does not exceed 100 m.

l

For the long-distance remote networking, the longest distance between an RRU and a BBU on a CPRI chain ranges from 100 m to 40,000 m.

Different CPRI optical cables are used in the two types of networking. For details, see chapter CPRI Optical Cable in the BBU3900 Hardware Description.

RFU Cabinets Supported by RFUs Restrictions for cabinets supported by RFUs are as follows: l

MRFUd and MRFUe must use Ver.C or Ver.D series cabinets.

l

There is no restriction for other RFUs.

5 RF System

In the same sector

RFUs that can be configured together are as follows: l All types of RFUs except DRFUs support hybrid configuration. l When different types of RFUs are used together, you must upgrade the software of the base station, base station controller, and CME to the required version, as shown in Table 5-25. l When an MRFUd is used together with a 1T2R RFU of another type: – The MRFUd does not work with the RFU to achieve the inter-module radio frequency (RF) frequency hopping function. – The MRFUd does not work with the RFU to achieve the dual-PA power sharing function. PA stands for power amplifier. l When a GRFU is used together with an MRFU or MRFUe: – If the MRFU or MRFUe is working in GSM mode, it can work with the GRFU to achieve the inter-module RF frequency hopping and dual-PA power sharing functions. In this case, the MRFUe supports a maximum of 6 carriers, and the difference between the number of carriers on the GRFU and the number of carriers on the MRFUe must not exceed 1. – If the MRFU or MRFUe is working in GU or GL mode, it cannot work with the GRFU to achieve the intermodule RF frequency hopping or dual-PA power sharing function. Take GRFU V2 hybrid configuration as an example, as shown in Figure 5-31.

Antenna System

The antenna system consists of antennas, feeders, jumpers, the Tower Mounted Amplifier (TMA), the Bias Tee (BT), and the GSM Antenna and TMA Control Module (GATM). It transmits and receives RF signals.

Antenna Antennas are used to radiate and receive radio waves. The working principle of antennas is as follows: RF signals output from a radio transmitter are transmitted to antennas over feeders. After receiving the signals, the antennas transmit them to a destination in the form of electromagnetic waves. At the destination, antennas receive the electromagnetic waves, convert them into RF signals, and transmit the signals to a radio transmitter over feeders. A remote control (RC) can control the downtilt of the remote electric tilt (RET) antennas remotely.

Feeders and Jumpers Feeders and jumpers are used to transmit RF signals between antennas and radio transmitters at minimum loss.

TMA The TMA is a low noise amplifier that is installed close to antennas. One end of the TMA is connected to an antenna port on an RF module while the other end is connected to antennas. By amplifying weak signals received by antennas, the TMA helps improve receive sensitivity of the BTS, expand the uplink coverage, and lower transmit power of MSs.

BT The BT couples the On-Off-Keying (OOK) signals or RF signals into the passive components of feeders.

GATM The GATM must be configured if the DRFU, RET antennas, and TMA are configured. Functions of the GATM are as follows: l

Controlling RET antennas.

l

Feeding power to the TMA.

Operation and Maintenance

About This Chapter Operation and Maintenance (OM) covers management, monitoring, and maintenance of the software, hardware, and configuration of the BTSs. In addition, diversified OM modes are provided in various scenarios. 7.1 OM Modes of the BTS The OM modes of the BTS consist of the Site Maintenance Terminal mode, Local Maintenance Terminal mode, and centralized network management mode. 7.2 OM Functions of the BTS The OM functions of the BTS consist of equipment management, software management, configuration management, service management, performance management, security management, alarm management, and environment monitoring.

Issue 12 (2012-12-30)


70



7.1 OM Modes of the BTS The OM modes of the BTS consist of the Site Maintenance Terminal mode, Local Maintenance Terminal mode, and centralized network management mode. Figure 7-1 shows the components of the BTS OM system. Figure 7-1 Network structure of the OM system

You can maintain the BTS in the following modes: l

Site Maintenance Terminal mode: The Site Maintenance Terminal is locally connected to the BTS through the Ethernet. You can use the Site Maintenance Terminal to operate and maintain the site, cell, Radio Carrier (RC), Baseband Transceiver (BT), channel, and board. In this mode, only one BTS can be maintained at a time.

l

LMT mode: The LMT is used to maintain the BTS through the OM links on the Abis interface, which is an interface between the BSC and the BTS. The LMT communicates with the BSC through a LAN. You can use the LMT to operate and maintain the site, cell, RC, channel, and board. This mode is used in configuring and modifying the data of the BSC and BTS.

l

Centralized network management mode: The Huawei iManager M2000 is used to maintain the BTS through the BSC. The M2000 can operate and maintain the site, cell, channel, and board. In this mode, multiple BTSs can be maintained at a time.

7.2 OM Functions of the BTS The OM functions of the BTS consist of equipment management, software management, configuration management, service management, performance management, security management, alarm management, and environment monitoring. Issue 12 (2012-12-30)


71



Equipment Management Provides the query function for the status of all the components (boards/modules) and all the external devices (power supply/environment monitoring/RET). You can also perform data configuration and status management for some devices.

Software Management Provides various functions, such as downloading and activating the BTS software, upgrading patches, and loading and downloading files. The associated tasks involve consistency check on the software and hardware releases, release management, and software upgrade.

Configuration Management l

Checks whether the added, deleted, or changed BTS data is consistent with the actual situation.

l

Supports automatic data backup.

l

Supports dynamic and static data configuration. In dynamic data configuration, the data immediately takes effect after modification; in static data configuration, the modified data takes effect after the BTS is reset.

Service Management l

Supports parameter setting and alarm query for the baseband boards and environment monitoring devices.

l

Supports complete self-test on hardware installation. The BTS software can be upgraded through the software package saved in the USB disk; thus, shortening the upgrade period. In addition, the local commissioning is not required. NOTE

The security of the USB loading port is ensured by encryption.

Performance Management l

Monitors the performance of the internal and external telecommunications networks and generates alarms when the performance deteriorates.

l

Monitors the operating status of the BTS, such as monitors the traffic volume on the ports and measures the technical data of the BTS.

8 External Reference Clock Sources

External Reference Clock Sources

The BTS supports multiple external reference clock sources, including the IP reference clock, E1/T1 reference clock, synchronous Ethernet reference clock, BITS reference clock, and GPS/ RGPS reference clock. If a BTS fails to obtain clock signals, it works in free-run mode for a certain period of time.

IP Reference Clock When a BTS works in IP over FE mode, it obtains clock signals from an IP reference clock. In this case, an IP clock server must be configured. The server sends the User Datagram Protocol (UDP) packets carrying reference clock information to the BTS. After receiving the packets, the BTS interprets clock signals from the packets and then synchronizes its clock system.

E1/T1 Reference Clock The BBU obtains clock signals from an E1/T1 port. Then, the BBU performs frequency division, phase locking, and phase adjustment on the clock module to export 2 MHz and 8 kHz clock signals for bit synchronization and frame synchronization. An E1/T1 reference clock obtains clock signals from the BSC or transport network. The BTS can obtain clock signals from the BSC using an E1/T1 port. If the BTS adopts IP transmission mode but an IP reference clock is unavailable, the BTS uses an E1/T1 port to obtain clock signals from the transport network.

Synchronous Ethernet Reference Clock When the BTS works in IP over FE mode and the transport network supports the synchronous Ethernet reference clock, the BTS obtains Ethernet clock signals from the transport network.

BITS Reference Clock When the BBU is configured with the USCU board, the GTMU board obtains external BITS clock signals from the USCU board.

GPS/RGPS Reference Clock When the BBU is configured with the USCU board, the GTMU board obtains external GPS/ RGPS clock signals from the USCU board. Issue 12 (2012-12-30)


74


8 External Reference Clock Sources

Free-Run Clock In the absence of external clocks, the internal free-run clock ensures that the BTS keeps working properly for at least ninety days.

NOTE

l * indicates that the UMTS mode is supported in terms of hardware. l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFU is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFU is located at a height of 4500 m to 6000m. l For the MRFU working in GSM mode, the maximum output power of each carrier on the MRFU is 60 W when the S1 configuration is applied. Note that, if the output power of 60 W is required, the related license must be obtained. l For the MRFU V2 working in GSM mode and operating in the 900 MHz frequency band: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFU V2 when the S1, S2, or S3 configuration is used. When the S4, S5, or S6 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFU V2. l For the MRFU V2 working in GSM mode and operating in the 1800 MHz frequency band, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained when the S4, S5, or S6 configuration is used. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFU V2. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFUd is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFUd is located at a height of 4500 m to 6000m. l For the MRFUd working in GSM mode: when the S1 or S2 configuration is applied, the maximum output power of each carrier on the MRFUd is 80 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFUd when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFUd. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFUe is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFUe is located at a height of 4500 m to 6000m. l For the MRFUe working in GSM mode: when the S1 configuration is applied, the maximum output power of each carrier on the MRFUe is 80 W; when the S2 configuration is applied, the maximum output power of each carrier on the MRFUe is 60 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFUe when the S1, S2, or S3 configuration is used. When any of the S4 through S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFUe. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l * indicates that the UMTS mode is supported in terms of hardware. l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3908 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3908 is located at a height of 4500 m to 6000m. l For the RRU3908 V2 working in GSM mode and operating in the 900 MHz frequency band: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3908 V2 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3908 V2. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3928 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3928 is located at a height of 4500 m to 6000m. l For the RRU3928 working in GSM mode: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3928 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3928. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3929 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3929 is located at a height of 4500 m to 6000m. l For the RRU3929 working in GSM mode: when the S1 or S2 configuration is applied, the maximum output power of each carrier on the RRU3929 is 60 W. If the output power of 60 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3929 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3929. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE

l The GSM receiver sensitivity is measured, as recommended in 3GPP TS 51.021, over the central band at the antenna connector on condition that the channel rate reaches 13 kbit/s and the bit error rate (BER) does not exceed 2%. The central band is the 80% of the full band. l The UMTS receiver sensitivity is measured, as recommended in 3GPP TS 25.104, over the full band at the antenna connector on condition that the channel rate reaches 12.2 kbit/s and the BER does not exceed 0.001. l The RRU3926 that works in GSM mode and operates in the 900 or 1800 MHz frequency band complies with the EN 301 502 V9.2.1 standard. The RRU3926 that works in UMTS or multiple service ring (MSR) mode and operates in the 900 or 1800 MHz frequency band complies with the ETSI EN 301 908 V5.2.1 standard and 3GPP TS 37.104 standard. l A x B W in the Output Power column indicates that this RF module is configured with A transmit channels and the maximum output power of each transmit channel is B W. l CD Non-MSR indicates that C data is carried on one transmit channel of an RF module while D data is carried on the other transmit channel of the RF module. CD MSR indicates that C and D data is carried on the same transmit channel of an RF module.

NOTE

l Power sharing assumes a random distribution of UEs in the cell. l If an RRU3926 is placed at an altitude of 3500 to 4500 meters, its power reduces by 1 dB. If an RRU3926 is placed at an altitude of 4500 to 6000 meters, its power reduces by 2 dB. l For the RRU3926 working in GSM mode: when the S1 configuration is applied, the maximum output power of each carrier on the RRU3926 is 80 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3926 when the S1, S2, or S3 configuration is used. When any of the S4 through S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3926. l Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.
