RNC V200R010

Product Description


2 Key Benefits

2.1 About This Chapter The design of the BSC6810 takes into consideration the factors such as services, capacity, transmission, and Operation and Maintenance (OM).

The BSC6810 brings the following benefits:

� All-IP Platform of Advanced Radio Controller � High Integration and Large Capacity � Flexible Configurations Adapting to Traffic Models � Resource Sharing Between Control Plane and User Plane � Multiple Clock Sources � Diverse Transmission SolutionsDiverse Transmission Solutions � Advanced RRM AlgorithmsAdvanced RRM Algorithms � Advanced Solutions to Radio Data ServicesAdvanced Solutions to Radio Data

Services � High Compatibility of Protocols

2.2 All-IP Platform of Advanced Radio Controller The BSC6810 uses the all-IP Platform of Advanced Radio Controller (PARC) developed by Huawei. PARC unifies the switching system of Asynchronous Transfer Mode (ATM), Time Division Multiplexing (TDM), and IP. Thus, it can serve as a uniform platform of GSM, CDMA, and WCDMA controllers. This platform can meet the requirements for the development of high-speed packet services and fully protect your network investment.

2.3 High Integration and Large Capacity The BSC6810 has the following features:

� The BSC6810 is highly integrated. Based on the Gigabit Ethernet (GE) star non-blocking switching on the Medium Access Control (MAC) sublayer, the BSC6810 achieves a central switching capacity of 120 Gbit/s.

� The BSC6810 supports up to 1,700 NodeBs and 5,100 cells.

RNC V200R010

Product Description


� The BSC6810 supports up to 51,000 Erlang voice traffic or a total of 3,264 Mbit/s PS throughput in the uplink (UL) plus downlink (DL). Such capacity, however, is implemented by only two cabinets.

� The BSC6810 provides a single-cabinet solution that supports 24,000 Erlang voice traffic or 1,536 Mbit/s (UL + DL) PS throughput.

2.4 Flexible Configurations Adapting to Traffic Mod els The number of signaling processing boards and that of data processing boards are flexible so that the quantity of resources on the user plane and control plane can meet the requirements of traffic models.

In the case that a single set ratio of board configuration is inconsistent with the actual traffic model, the flexible configurations of boards in the BSC6810 help prevent wasting resources. The waste of control plane resources may attribute to the bottleneck at user plane resources, and the other way round.

2.5 Resource Sharing Between Control Plane and User Plane

In BSC6810, an SPUa board has four independent subsystems. Each subrack has a subsystem working as the Main Processing Unit (MPU) subsystem for the management of resources on the user plane and resource allocation during a call. The other subsystems work as Signaling Process Unit (SPU) subsystems, which process signaling messages on the Iu, Iur, Iub, and Uu interfaces to implement the signaling processing function.

The SPU subsystems, working as the processor for control plane data, form a control plane resource pool; the DSPs, working as the processor for user plane data, form a user plane resource pool.

The resources of control plane and user plane within a subrack are managed and allocated by the MPU subsystem. When a new call travels to the subrack, the MPU subsystem forwards the resources request to other subracks in case of overload. If any subrack has enough resources of control plane and user plane, the new call can be successfully processed.

2.6 Multiple Clock Sources Multiple clock sources are available for the BSC6810. Thus, the BSC6810 can select system synchronization clocks conveniently.

The available clock sources are as follows:

� Building Integrated Timing Supply System (BITS) � Global Positioning System (GPS) � Line clock extracted from the Iu interface � External 8 kHz clock provided by an external device

The BSC6810 can set a priority for each clock source.

RNC V200R010

Product Description


If the BSC6810 fails to obtain any external clock, the BSC6810 obtains its working timing signals from the local oscillator. The timing signals generated by the local oscillator, however, do not meet the requirements of NodeBs for the clock precision. Therefore, when the BSC6810 uses such timing signals, the NodeBs fail to obtain timing signals from the BSC6810.

2.7 Diverse Transmission Solutions The BSC6810 provides diverse transmission solutions by supporting:

� Multiple Iub Network Topologies � Multiple Types of Transmission Port � High Reliability of Transmission � Flexible Configuration of Interface Boards � IP Transport on the Iub/Iur/Iu Interfaces � Hybrid IP Transport on the Iub Interface � ATM/IP Dual Stack on the Iub Interface � Satellite Transmission on the Iub Interface � Efficient Transmission on the Iub Interface � Dynamic Management of the Bandwidth � Inverse Multiplexing on ATM � Fractional Functions � Timeslot Cross Connection � Multilink PPP

2.7.1 Multiple Iub Network Topologies The BSC6810 supports multiple Iub network topologies, such as star, chain, and tree topologies. The type of topology depends on the site requirement.

2.7.2 Multiple Types of Transmission Port The BSC6810 provides multiple types of physical transmission port for the Iub, Iur, and Iu interfaces.

The ATM transmission ports are of the following types:

� E1/T1 � Unchannelized STM-1/OC-3c � Channelized STM-1/OC-3

The IP transmission ports are of the following types:

� E1/T1 � Unchannelized STM-1/OC-3c � Channelized STM-1/OC-3 � Fast Ethernet (FE) � GE

RNC V200R010

Product Description


2.7.3 High Reliability of Transmission To achieve high reliability of transmission, the BSC6810 uses the following solutions:

� Transmission port redundancy

− Unchannelized optical ports support Multiplex Section Protection (MSP) 1:1 or MSP 1+1 redundancy.

− Channelized optical ports support MSP 1:1 redundancy.

− FE or GE ports support redundancy and load sharing between the ports. � Diverse ways of fault detection:

− Quick check based on Bi-directional Forwarding Detection (BFD)

− Address Resolution Protocol (ARP) check

− End-to-end ATM Continuous Check (CC) based on the F5 protocol

2.7.4 Flexible Configuration of Interface Boards The BSC6810 does not place restrictions on which slots hold interface boards for the Iub, Iur, or Iu. A subrack can host different types of ATM and IP interface board at the same time.

2.7.5 IP Transport on the Iub/Iur/Iu Interfaces In addition to ATM transport, the BSC6810 supports IP transport on the Iub, Iur, and Iu interfaces. This is consistent with the evolution to an all-IP network, provides sufficient bandwidth for high-speed and large-volume data services, and reduces the cost of construction, operation, and maintenance of transport networks.

2.7.6 Hybrid IP Transport on the Iub Interface When IP transport is applied to the Iub interface, data of different priorities can be transmitted separately through E1/T1 ports and FE ports. The transmission mode of a service depends on the Quality of Service (QoS) requirement. Services with high QoS requirements are transmitted through E1/T1 ports, and those with low QoS requirements are transmitted on the Ethernet.

Hybrid IP transport guarantees the QoS and provides sufficient interface bandwidth for high-speed PS services such as High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), thus saving the transmission cost and protecting the investment of operators.

2.7.7 ATM/IP Dual Stack on the Iub Interface ATM/IP dual stack is supported between the BSC6810 and a NodeB. Services with high QoS requirements are transmitted through ATM, while those with low QoS requirements through IP.

Such data transmission guarantees the QoS and provides sufficient interface bandwidth for high-speed PS services such as HSDPA and HSUPA, thus saving the transmission cost and protecting the investment of operators.

2.7.8 Satellite Transmission on the Iub Interface The BSC6810 supports satellite transmission on the Iub interface to cover isolated areas.

RNC V200R010

Product Description


2.7.9 Efficient Transmission on the Iub Interface The BSC6810 improves transmission efficiency by taking the following techniques on the Iub interface:

� Iub overbooking and Frame Protocol Multiplexing (FP MUX)

Without additional transmission devices, the BSC6810 improves the efficiency of transmission on the Iub interface, thus increasing the revenue of operators.

− With Iub overbooking, the BSC6810 can estimate the bandwidth of a service on the Iub interface and allocate an appropriate bandwidth to the service. In this way, the Iub transmission efficiency increases greatly.

− With FP MUX, the BSC6810 can multiplex Iub FP data. That is, the BSC6810 multiplexes multiple User Datagram Protocol (UDP) or IP packets into one data packet in a specific format before transmitting it, thus increasing the efficiency of IP transport on the Iub interface.

� IP shaping/policing

Usually, the links on the NodeB side are low-speed ones. When a high-speed port on the BSC6810 connects to a low-speed port on a NodeB, packet loss may occur if the BSC6810 transmits packets to the NodeB. IP shaping/policing, however, can prevent such packet loss, balance traffic, and improve the efficiency of transmission on the Iub interface.

2.7.10 Dynamic Management of the Bandwidth The BSC6810 detects the IP QoS information, such as the packet loss rate, delay, and delay variation. Based on the QoS, the BSC6810 then adjusts the bandwidth of logical ports and of resource groups. Thus, the transmission efficiency is enhanced.

2.7.11 Inverse Multiplexing on ATM The BSC6810 provides the Inverse Multiplexing on ATM (IMA) function over E1/T1 links. An ATM cell stream from a high-speed transport link is multiplexed inversely onto multiple low-speed E1/T1 links. Then, at the receiver end, the low-speed cell streams are converged to the original high-speed cell stream.

The IMA function enables high-speed transmission through low-speed links. Thus, it broadens the application scope of E1/T1 links. In addition, this function has a relatively high fault tolerance. Provided that the number of working links is not smaller than the specified minimum number of active links in an IMA group, services can continue. Thus, the IMA function ensures high transmission reliability.

2.7.12 Fractional Functions The BSC6810 provides the fractional functions, that is, fractional ATM and fractional IMA. The fractional functions enable 3G equipment to share the E1/T1 links of a 2G network with 2G equipment, thus allowing 2G and 3G concurrent transmission.

With the fractional functions, you can quickly deploy NodeBs at an early stage of WCDMA network construction by using the existing 2G transmission resources. Thus, you can launch the system at a comparatively low cost and within a relatively short period of time.

RNC V200R010

Product Description


2.7.13 Timeslot Cross Connection The BSC6810 supports the timeslot cross connection function. The 2G equipment cross-connects the timeslots on a 2G link to the BSC6810, so as to enable concurrent transmission of 2G and 3G data. Such timeslot cross connection does not require additional timeslot cross connection equipment.

2.7.14 Multilink PPP The BSC6810 provides the Multilink PPP (MLPPP) function. This function combines physically independent links to form only one logical channel. Thus, the network layer can send data directly to this logical channel. The MLPPP function provides a relatively high bandwidth and implements rapid data forwarding.

2.8 Advanced RRM Algorithms The BSC6810 uses Huawei-patented Radio Resource Management (RRM) algorithms in the following functions:

� Power control � Handover � Radio resource allocation � Call Admission Control (CAC) � Load control

In addition, the BSC6810 applies these algorithms in new features such as HSDPA, HSUPA, and Multimedia Broadcast and Multicast Service (MBMS). Thus, the BSC6810 offers optimum network coverage, capacity, and quality.

2.8.1 Power Control The BSC6810 uses outer loop power control algorithms. It aims to provide the required quality for UEs when the radio environment changes and to increase the usage of system capacity.

2.8.2 Handover The BSC6810 supports flexible handover strategies and parameter configurations. Based on different coverage areas, services and loads, it performs different kinds of handover, such as intra-frequency handover, inter-frequency handover, and inter-RAT handover. Thus, it improves the speech quality, reduces the call drop rate, and implements traffic absorption in special areas.

2.8.3 Radio Resource Allocation Based on the QoS requirements, actual traffic volume, and actual cell load, the BSC6810 can allocate resources dynamically. Thus, it fulfills the communication requirements and increases the efficiency of radio channel resources.

RNC V200R010

Product Description


2.8.4 CAC and Load Control The BSC6810 applies multiple Huawei-patented technologies, such as load sharing and admission based on rate downsizing, to balance loads between cells and to control service access. Thus, it increases the system capacity and guarantees the current QoS.

2.8.5 Service Differentiation Based on Subscriber P riorities Based on the allocation retention priorities set at the CN for subscribers, the BSC6810 can set the subscribers to three levels: gold, silver, and bronze. The BSC6810 then provides different services for the three levels of subscribers.

� Based on priorities of subscribers, the BSC6810 sets different Guaranteed Bit Rates (GBRs) for Best Effort (BE) services of different subscribers. GBR guarantees that the basic requirements of BE services are met.

� With the pre-emption algorithm, high-priority subscribers can pre-empt the resources over low-priority subscribers.

� With the algorithm of rate downsizing against congestion, the BSC6810 preferentially downsizes the rates of low-priority subscribers to their GBRs.

� With the scheduling algorithm, the BSC6810 proportionally allocates bandwidths to subscribers. This algorithm takes subscriber priorities into account in the condition that the GBRs of the subscribers are guaranteed.

� With the flow control algorithm, the BSC6810 proportionally allocates bandwidths to subscribers. This algorithm takes subscriber priorities into account in the condition that the GBRs of the subscribers are guaranteed.

When radio resources are limited, the BSC6810 can guarantee GBRs of subscribers before allocating the remaining resources proportionally.

2.9 Advanced Solutions to Radio Data Services The BSC6810 adopts the advanced technologies, such as HSDPA, HSUPA, and MBMS, to meet the requirements of different types of data service.

2.9.1 HSDPA The BSC6810 adopts HSDPA as the solution for high-speed DL data transmission. The DL rate for a single UE can reach up to 14.4 Mbit/s on the physical sublayer.

In addition, the BSC6810 supports VoIP over HSDPA and IMS over HSDPA, where VoIP stands for Voice over IP and IMS stands for IP Multimedia Subsystem.

HSDPA enhances the performance of the WCDMA network in the following aspects:

� Higher DL data rate � Shorter service delay and more pleasant user experience in high-speed services � More efficient DL coding and power utilization

2.9.2 HSUPA The BSC6810 adopts HSUPA as the solution for high-speed UL data transmission. The UL rate for a single UE can reach up to 5.76 Mbit/s on the physical sublayer.

RNC V200R010

Product Description


In addition, the BSC6810 supports VoIP over HSUPA and IMS over HSUPA.

HSUPA enhances the performance of the WCDMA network in the following aspects:

� Higher UL data rate � Shorter service delay and more pleasant user experience in high-speed services � Faster UL resource control � Better quality of service

2.9.3 MBMS The BSC6810 adopts MBMS to provide the high-speed multimedia broadcast service. The transmission rate of MBMS services can reach up to 256 kbit/s.

MBMS enhances resource efficiency and provides diversified multimedia services.

2.10 High Compatibility of Protocols The BSC6810 is developed according to 3GPP R6 specifications. It is compatible with other Network Elements (NEs) and UEs based on 3GPP R6, R5, R4, or R99 specifications.

Product Description


RSR

The RSR provides the single-cabinet solution.

The RSR has the following components:

� One RNC Switching Subrack (RSS) � Zero to two RNC Business Subracks (RBSs)

RBR

The RBR is configured when the required service processing capability exceeds the specifications for the RSR. At most one RBR can be configured.

The RBR is configured with only RBSs. The number of RBSs in the RBR ranges from 1 to 3. If the RBR is configured with one or two RBSs, the RBSs should be configured from the bottom to the top.

3.2.3 Subrack Components The BSC6810 has two types of subrack, according to board configuration. They are the RSS and the RBS. The BSC6810 can be configured with up to six subracks. Among the subracks, one is the RSS, and the others are RBSs. The number of RBSs ranges from 0 to 5.

The subracks of the BSC6810 have a standard width of 19 inches, which complies with the IEC60297 standard. The height of a single subrack is 12 U. In a subrack, the backplane is positioned in the middle, and front and rear boards are installed on both sides of the backplane, as shown in Figure 3-3. The slots are of the same length.

BAM: Back Administration Module FAM: Front Administration Module LMT: Local Maintenance Terminal IP: Internet Protocol VLAN: Virtual Local Area Network

The LMT is the OM terminal on the NE side. It can access the BAM through Virtual Local Area Network (VLAN), an intranet, and the Internet.

The LMT is an intelligent Man Machine Language (MML) client working in Graphic User Interface (GUI) mode. It provides the BSC6810 with OM functions.

Through an external alarm box, the LMT can report audible and visible alarms if faults are detected.

4.3 OM Functions The BSC6810 provides MML commands and GUIs as an interface for system management, configuration, maintenance, alarm management, and so on. Such an interface is explicit and easy to use. In addition, the BSC6810 can check the data integrity for an MML command to be run.

This section describes the following OM functions:

� Security Management � Configuration Management � Maintenance Management � Fault Detection

RNC V200R010

Product Description


� Performance Management � Alarm Management � Loading Management � Status Monitoring � Message Tracing � Log Management � Software Management

4.3.1 Security Management BSC6810 security management provides the following functions:

� Grade-based operator right setting

You can set the operator right, operation time limit, and password to ensure system security and operation flexibility.

� Operator information protection

If no operation is performed for a certain period, the user interface is automatically locked.

� File Transfer Protocol (FTP) transmission based on ciphering

This ensures the security of FTP transmission. � Encryption of the communication interface between the BSC6810 and the

Element Management System (EMS)

The BSC6810 uses the Security Socket Layer (SSL) protocol to fulfill transmission of ciphertext over the OM channel between the BSC6810 and the EMS. This ensures data security.

4.3.2 Configuration Management The BSC6810 provides certain functions for configuration management. These functions are described in the following topics.

Automatic Data Configuration

The BSC6810 can automatically generate the configuration data that is necessary for internal physical and logical connections and configure the data for the corresponding parts. No manual configuration is required. You need to configure only the data for connections between the BSC6810 and external devices, thus improving the serviceability of the BSC6810.

Online and Offline Data Configuration

The BSC6810 supports the following configuration modes:

� Offline data configuration

In offline data configuration mode, configuration data is stored only in the BAM. The data is not sent to the host before being loaded onto the host. Therefore, this mode increases the efficiency of configuring a large amount of data. The BSC6810 also supports offline data configuration based on host subracks. Therefore, it allows capacity expansion without disrupting services.

RNC V200R010

Product Description


� Online data configuration

In online data configuration mode, configuration data is sent to the host immediately after the configuration. There is no need to reset the BSC6810 or to reload the data. Thus, dynamic data configuration is enabled.

Dynamic Batch Data Configuration

The BSC6810 supports dynamic configuration of data in batches. With this function, the batch data configuration scripts are executed when the BSC6810 is offline. After the BSC6810 switches to the online mode, the BAM sends all the configuration data to the host in batches. The data takes effect with no need to restart or reset the subracks or boards. This avoids disrupting ongoing services.

In the case of bulk data modification, such as NodeB reparent and change of interface board types, dynamic batch data configuration improves efficiency.

Data Configuration Right Control

Under data configuration right control, only one user has the right to perform data configuration for the BSC6810 at any time. The configuration is allowed on only one configuration console at a time, that is, either on the LMT or on the M2000.

With the control, data configuration on the LMT and that on the M2000 are not allowed at the same time, thus improving reliability of the BSC6810.

Data Configuration Rollback

The BSC6810 provides the data configuration rollback function. If data configuration fails to achieve the expectation or even causes equipment or network exceptions, you can perform rollback to restore the configurations quickly. This ensures proper running of the BSC6810.

Data Backup

When two OMUa boards are configured, they work in active/standby mode. The data on the standby OMUa is synchronized with that on the active OMUa. The BSC6810 supports automatic and manual data backup. It provides a data backup and recovery tool.

Data Validity Check

The BSC6810 can check the integrity and consistency of configuration data, such as the data of a cell.

Configuration Data Query

The BSC6810 supports the object-based query of configuration data.

Online Reconfiguration of the RINT and Backup Mode

The BSC6810 supports online reconfiguration of the RINT and of the board and port redundancy mode, thus facilitating reconfiguration of services.

RNC V200R010

Product Description


Dynamic Assignment of IP Addresses to a NodeB

When ATM transport is applied to the Iub interface, the BSC6810 uses the Bootstrap Protocol (BOOTP) to automatically assign the OM IP address to a NodeB.

When IP transport is applied to the Iub interface, the BSC6810 uses the Dynamic Host Configuration Protocol (DHCP) to automatically assign the OM IP address to the NodeB.

Compared with BOOTP, DHCP has relatively powerful functions. In addition, DHCP is compatible with BOOTP.

Product Description


5 Reliability


� System Reliability � Hardware Reliability � Software Reliability

5.2 System Reliability The system reliability design of the BSC6810 takes into account the following techniques:

� Load control

The system performs load control based on the CPU usage, traffic over each interface, and radio resource load of the system. Thus, the BSC6810 can keep on working in case of CPU overload and resource congestion. In this way, the system reliability is enhanced.

� Dynamic sharing of resources in the system

The DPUb boards and DSPs work in resource pool mode, that is, all the DSPs in a subrack work as a resource pool. The MPU in a subrack manages and allocates all the user plane resources within the subrack to fulfill intra-subrack sharing of user plane resources.

In case of overload, the MPU forwards Radio Resource Control (RRC) connection requests to other subracks, so as to fulfill inter-subrack sharing of user plane resources and intra- and inter-subrack sharing of control plane resources.

� Port trunking

SCUa boards support port trunking. This function allows data backup in case of link failure, thus preventing inter-plane switchover and cascading switchover and improving the reliability of intra-system communication.

� Dual planes for timing signal transmission

The BSC6810 provides the dual planes for transmission of timing signals between the GCUa/GCGa and SCUa boards.

The active and standby GCUa/GCGa boards are connected to the active and standby SCUa boards through the Y-shaped cables. This connection mode ensures proper working of the timing signals for the system if a single-point failure

RNC V200R010

Product Description


occurs to the GCUa/GCGa, cable, or SCUa. In addition, with the Y-shaped cable, switchover between GCUa/GCGa boards does not affect the SCUa boards.

� Transmission port backup

− Unchannelized optical ports support MSP 1:1 or MSP 1+1 redundancy.

− Channelized optical ports support MSP 1:1 backup.

− FE or GE ports support port backup and load sharing between the ports.

All these improve the reliability of transmission. � OM dual planes

To improve the reliability of OM channels, the BSC6810 provides the OM dual planes, including dual OMUa boards, dual Ethernet adapters, and dual main control boards.

� Crystal Aging Compensation technology

The BSC6810 adopts the Huawei-patented Crystal Aging Compensation technology to compensate for frequency deviation caused by the aging of temperature-constant crystal oscillators. This technology protects the clock precision from the influence of the aging of the crystal oscillators and ensures long-term stability and reliability of the system clock.

� Dual –48 V power supplies

The two independent –48 V power supplies operate at the same time to ensure normal operations in case either of them fails. The failed supply can be restored without a power cut. This improves the reliability and availability of the power system.

5.3 Hardware Reliability The BSC6810 adopts the reliability design such as board and port backup and load sharing. In addition, the BSC6810 improves the reliability and maintainability by optimizing the fault detection and isolation techniques for boards and the whole system.

The hardware reliability design of the BSC6810 takes into account the following techniques:

� The system uses the multi-level cascaded and distributed cluster control mode. Several CPUs form a cluster processing system. Each module has distinct functions. The communication channels between modules are based on the backup design or anti-suspension/breakdown design.

� The system uses the redundancy design, as shown in Table 5-1, to support hot swap of boards and backup of important modules. Therefore, the system has great error tolerance.

Table 5-1 Parts redundancy

� When an entity fails, the isolation mechanism transfers the services to another entity for processing. After the system finds a faulty board in the resource pool, it isolates the board. Then another board in the resource pool will process the subsequent services.

� When a board with a single function fails, restarting the system might clear the fault.

� All boards support dual-BIOS. Faults at one BIOS do not affect startup or operation of the boards.

� The system uses the non-volatile memory to store important data. � With advanced integrated circuits, the system features high integration, good

technology, and high reliability. � All the parts of the system pass the aging test. The process of hardware

assembly is strictly controlled. These methods ensure the high stability and reliability for long-term operation.

5.4 Software Reliability The error tolerance ability of the software system indicates the software reliability. In other words, the whole system can keep on working in case of software failure. This indicates that the system has self-healing ability. The BSC6810 derives this ability from the following aspects:

� Regular check of key resources

Usage check is provided for various software resources in the system. If a resource is unavailable because of a software error, the unavailability lasts only a short time. The reason is that the check mechanism ensures the release of this resource and the output of logs and alarms.

� Task monitoring

RNC V200R010

Product Description


During the running of software, the BSC6810 monitors the internal errors of all software and some hardware faults, if any. It then reports the errors and faults to the OM system.

� Load sharing

The FG2a and GOUa boards support inter-board load sharing between ports.

The DPUb boards work in resource pool mode. If a DPUb board is faulty, other DPUb boards in the same subrack take over the services carried on the faulty board.

� Data check

The system is able to perform regular or event-driven check for data consistency and export the related log records and alarms.

� Dual versions

The boards of the BSC6810 have active/standby workspaces. The active workspace stores the current version files, and the standby workspace stores the version files except those in the active workspace.

Switchover between the active and standby workspaces can be performed to upgrade or roll back the RNC version. Therefore, the active and standby workspaces facilitate the upgrade of and rollback for the RNC and greatly reduce the time of service disruption caused by the upgrade.

� Data backup

The BAM data and FAM data can be backed up, so that the reliability and consistency of the data are ensured.

� Storage of operation information

The BSC6810 records the operations that you perform and saves the records in the operation log. You can use the operation log to identify and clear errors or faults caused by operations.

� Flow control

The BSC6810 automatically controls the flows on the Iub, Iur, and Iu interfaces to avoid overload caused by heavy traffic.
