The above-mentioned interfaces are standard interfaces, which can interconnect withequipment from other manufacturers.

1.3 Product FeaturesAdvanced ArchitectureThe ZXUR 9000 UMTS system is based on the ETCA architecture, providing standardplatform architecture for carrier-class applications, with features like high reliability andmaintainability.

The ETCA architecture provides additional rear boards as compared with the standardATCA architecture. Without sacrificing the capacity of front boards, the added rearinterface boards can improve the processing capacity with more interfaces for NEs, whichneed a relatively larger amount of low-speed interfaces.

More Scalable Software PlatformThe ZXUR 9000 UMTS system software adopts the Linux multi-process architecture. Themiddleware concept is introduced for restructuring software design to enable a highlycohesive system with loose coupling.

The multi-process architecture ensures the independence of individual processes,separating the errors occurring within one process from others, and enhancing the systemcapacity and security.

All the key components employ 11 active/standby backup mode, and other componentsadopt load sharing mode. With high application reliability, ZXUR 9000 UMTS employs theLinux operating system, and supports active/standby mode of process-class software.

Environment-Friendly Design

The system is designed by observing relevant environment preserving regulations andstandards. The increasing energy tense and ever deteriorating environment have madeenvironment-friendly design and low power consumption important concerns for telecomoperators, who not only take environment preservation a social responsibility and a meansfor reducing cost, but also promote the formulation of relevant regulations and standards.

Compared with two independent controllers, ZXUR 9000 UMTS reduces the powerconsumption itself by employing a set of physical devices to deploy two logic networks.Besides, the overall power consumption of the system is reduced with advanced technicalmeasures from ZTE corporation. Such as, utilization of radio resources is improvedthrough the message interaction among different modes, to achieve a perfect dynamicpower-consumption management strategy, and some carriers and boards of low utilizationcan be shut off appropriately, to reduce power consumption and save energy.

More Competitive Evolution Potential

ZXUR 9000 UMTS provides varieties of external interfaces that are compatible with bothfull-IP requirements and traditional E1 and ATM network access.

Supporting evolution to IPV6.

In addition, it is compatible with future development: the media access system considersthe operator's investment benefit in that it is compatible with multi-mode application andthe evolution to LTE, HSPA+.

Easy Operation and Maintenance

Besides, ZXUR 9000 UMTS adopts a new hardware architecture, which embodiesthe operation and maintenance board, the data switching and processing board, theinterface board, and the service processing board, to reduce the board backup typesand maintenance costs, and facilitate daily maintenance by providing a unified externaloperation and maintenance platform among different modes.

2.2 Interface Signalling ProcessingInterface signalling processing involves the control-plane processing of each interface. Itimplements the following functions:

l Radio access bearer allocation and releasel Security mode controll Node B Logic Operation & Maintenancel Synchronizationl NAS Message Distributionl System message broadcastl Paging support

2.2.1 Radio Access Bearer Allocation and ReleaseIn the process of call connection setup, the RNC is responsible for allocation of radiochannel resources and ground bearer resources according to the QoS requirements ofthe radio access bearer as well as resource release when they are not used.

2.2.2 Node B Logic Operation & MaintenanceThis function is provided for the logic operation & maintenance of the Node B radionetwork resources. It includes cell and common transmission channel configuration,blocking and unblocking of logic resources according to equipment running, check ofconfiguration consistency with Node B, and so on.

2.2.3 Security Mode ControlSecurity mode control involves radio channel ciphering and deciphering, andcompleteness protection.

l The objective of radio channel ciphering and deciphering is to protect userdata information transmitted over the air to avoid information acquisition by anunauthorized third party. The ciphering and deciphering is performed on the basisof session-related information and key as well as related ciphering algorithms.According to the 3GPP specification, the F8 and KASUMI algorithms are adopted asthe ciphering algorithms.

2-2


Chapter 2 Functions

basis of session-related information and key as well as related ciphering algorithms.According to the 3GPP specification, the F9 and KASUMI algorithms are adopted asthe ciphering algorithms.

2.2.4 SynchronizationSynchronization in UTRAN involves network synchronization, node synchronization, andradio interface synchronization.

2.2.5 NAS Message DistributionRNC should be responsible for forwarding of non-access layer NASmessages betweenUEand CN. During uplink forwarding, the RNC can determine the CN domain that a messageis to be forwarded to according to the CN domain ID carried in the message.

2.2.6 System Message BroadcastThe system message broadcast provides the UE with the access layer and non-accesslayer information needed in acquisition of the UMTS service.

2.2.7 Paging FunctionThe objective of the paging function is to enable a UE to receive the notification of beingcalled in various states, thus contacting the network.

2.3 Radio Resources ManagementRadio resources management (RRM) allocates and uses air interface resources, to ensurethe service quality of the system (QoS), and to obtain the planned coverage area andimprove capacity.

The radio resources management involves the radio measurement, access control, loadcontrol, power control, handover control, dynamic radio bearer control, congestion control,code resources management, and load balance.

2.3.1 Radio Measurement FunctionThe objective of radio measurement is to measure the radio channel quality. Themeasurement types may include the RX signal intensity of the current and adjacent cells,bit error ratios of the current and adjacent cells, RX interference level, total downlink TXpower of each cell, transmission scope, Doppler shift, synchronization status and so on.The measurement results are used in handover decision, access control, load controland so on.

2-3



2.3.2 Access Control FunctionWhen new cell resources are requested (such as new services accessing to a cell,increased rate of PS services borne on DCH, service status switchover between FACHand DCH or between DCH and HSPA), access control function is to decide whetherto access new service requirements according to the current resources, to prevent thesystem from overload, and to keep the system reliable. In addition, access control isto access services to a great extent, when services are adequate, fully utilizing systemresources and ensuring OoS of users.

New services are requested under such scenarios as RRC connection establishment,RAB establishment, RABmodification, SRNC relocation, Iur interface handover, Intra-RNChandover, and dynamic channel allocation. After receiving the request, RNC, accordingto the service attribute and equipment capability, selects the transmission channel type.After that, it decides whether to access corresponding channels according to the resourcesutilization of the target channel of the current cell, and the resources needed by services.When new cell services are requested, RNC balances the system resources in advanceaccording to cell resources utilization, to prevent inadequate resources during access, andprevent the cell from overload after access.

The RAN equipment from ZTE Corporation implements access control according topriorities. That is, users and services with higher priority are likely to obtain more systemresources and better QoS service.

2.3.3 Load Control FunctionLoad control is to monitor the system load. When the system is close to overload or alreadyin the overload status, it is used to control the system so that it can smoothly return to thestable status as best as possible. When the system returns to the stable status, it can alsobe used to control the traffic to acquire better QoS service (such as a better rate, or highertransmission reliability).

2.3.4 Power Control FunctionThe power control of RNC involves the downlink/uplink open-loop power control, powerbalance, and uplink/downlink outer-loop power control.

l Downlink open-loop power control is used to set the initial TX power of a downlinkchannel according to a UEs downlink measurement report.

l Power balance, when RNC achieves macro diversity balance, is to balance thetransmitting power of several downlink radio links and solve power offset.

l Uplink outer loop power control is to set the quality target value of Node B uplink innerloop power control by means of quality estimation of the transmission channel, thusachieving the objective of controlling uplink radio channel quality within a long sector.

l Uplink open-loop power control is used to set the initial TX power of a UE accordingto the UEs measurement report information in cases like random access.

l Downlink outer loop power control is performed by UE. It is to set the quality targetvalue of its downlink inner loop power control by means of quality estimation of the

2-4


Chapter 2 Functions

transmission channel too, thus achieving the objective of controlling the downlinkradio channel quality within a long sector. RNC is responsible for setting of someparameters used in downlink outer loop power control.

2.3.5 Handover Control FunctionHandover control is based on radio measurement, which is used to perform mobilitymanagement over the radio interface and ensure the core networks QoS requirement. Itinvolves the following types of handover control:

l Intra-RNC soft handover

The intra-RNC soft handover indicates that the Node Bs where the cells involved insoft handover are located are under the administration of one RNC.

l Intra-RNC softer handover

The intra-RNC softer handover indicates the handover among several cells under theadministration of one Node B. The cells connect with UE at the same time, which iscalled macro diversity.

l Inter-RNC soft handover

The Inter-RNC soft handover falls into two types: One is performed between sectorswith the same frequency under different Node Bs, the other is performed betweenNode Bs under the administration of different RNCs through crossing the Iur interface.

l Intra-RNC hard handover

Refers to the hard handover between Node Bs under the administration of the sameRNC.

l Inter-RNC hard handover

It refers to the hard handover between Node Bs under the administration of differentRNCs.

l Reverse handover

It refers to the UE-controlled handover in case the configuration fails or underconditions such as adverse radio environment (CELL UPDATE and URA UPDATE forinstance). It also includes intra-RNC and inter-RNC handover, that is, the intra-RNCreverse handover and inter-RNC reverse handover.

l SRNS relocation

It refers to the shift of the Iu interface connection from SRNC to DRNC after all theradio links have been shifted to DRNC.

l Inter-system handover

It refers to the mobility management of UE from one radio access system to anotherradio access system (from UTRAN to GERAN). It requires that UE supports WCDMAand GSM modes. In addition, the GSM system should provide correspondingfunctions to support handover between different systems.

2-5



l Change of HSDPA and HSUPA serving cells

During the soft handover in the system, when the best cell changes, if the HS-PDSCHchannel exists before and after the handover, the HS-PDSCH serving cell is triggeredto change. If the HS-PDSCH channel exists before and after the hard handover, theHS-PDSCH serving cell will be changed. Only one of the HSDPA and HSUPA servingcells exists.

2.3.6 Dynamic Radio Bearer ControlDynamic radio bearer control (DRBC), according to user's demand and system resourcesutilization, is to reasonably allocate resources during the system operation, to fully utilizebandwidth.

The DRBC control module dynamically adjusts the bearing channel of PS and CS servicesand the real-time rate, ensuring the full utilization of radio resources of the system, andthe system reliability and the Qos of services.

The DRBC strategies involve:

l Initial channel allocation. When the channel is set up initially, proper channel and rateconfiguration are allocated to services according to service demand and the systemstatus. It includes the channel allocation of signalling, initial services, and concurrentservices.

l Channel migration. Proper transmission channel configuration is selected for the PSservices according to their actual rates. The channel type can be changed with therate of PS services. When the actual data traffic of users is lower than the bandwidthallocated by the system, the bandwidth is reduced to save resources. When theactual data traffic of users is close to their allocated bandwidth, the bandwidth isproperly improved to prevent services of users from being affected. During thesession, the dynamic radio bearer control is to adjust the service bandwidth inreal time and perform handover between channels according to the measurementresults. The conversational CS services occupy the downlink/uplink DCH channel,the streaming services occupy the DCH-type channel, and the interactive andbackground services occupy the FACH and DCH-type channels. The migration fromPCH to DCH is not supported, but the status migration among PCH, FACH, and DCHis supported.

2.3.7 Congestion Control FunctionCongestion control is to reallocate radio resources when the system is congested, andalleviate congestion according to the service attribute, to improve connection rate, andmake services with different priorities utilize system resources reasonably.

When the uplink/downlink loads are close to or over the access control threshold, newservices cannot be accessed due to inadequate resources. That is, congestion occursto the system, which calls for RNC to implement congestion control strategies. Theservice request includes RAB establishment, modification/negotiation/renegotiation

2-6


Chapter 2 Functions

of SRNC access and relocation, cross-Iur RL setup, intra-RNC incoming handover,inter-system handover, inter-frequency handover, inter-RNC incoming handover, RABtwo establishments of the same user, and the improvement of service rate triggered bythe dynamic radio bearer adjustment.

When congestion occurs to the system, functions preempted by resources can betriggered, to show the difference of users with different priorities and improve the callconnection rate of the system. Two main strategies are as follows:

l Release by force: High-priority services with forcible release capability can releasethe services of users with low priority. User with high priority achieves access throughthe preemption of users with low priority and whose services can be released by force,to show the service difference among users.

l Reduce the rate: The data rate of online users is reduced to improve the callconnection rate.

2.3.8 Code Resources Control FunctionCode resources control is to dynamically allocate downlink channelized code for a cellaccording to a certain standard, to utilize code resources to a great extent, and to improvethe system capacity.

During the service setup, RNC calculates SF and allocate corresponding channelized codeaccording to the service rate. After the service is released, the channelized code is alsoreleased to allocate to other users. For each cell, RNC maintains a channelized codetable, and records such statuses of each code as idle, allocated, or shielded. During codeallocation, the shielding of idle code resources blocks should be reduced initially.

When HSDPA and R99 use the same carrier, the throughput of the HSDPA services ineach cell are affected by the number of the HS-PDSCH channels, that is, the number (16)of SFs allocated to the HS-PDSCH channel. ZTE RNC supports the number of channelsstatically allocated or the number of channels dynamically allocated to HS-PDSCH. Thedynamic allocation can reflect the change of system loads more rapidly and flexibly.

2.3.9 Load Balancing FunctionThe load balancing function is used to appropriately distribute traffic in accordance withcell load and neighbor relations between cells for effective use of system resourcesand improvement of system capacity and QoS. The RNC supports both Intra-RATand inter-RAT load balancing. The intra-RAT load balancing may be implemented byload-based or traffic-based inter-operations among multiple carriers.

With the frequency priority settings, the RNC supports configuring a cell to support HSDPAor HSUPA and setting access priorities for voice traffic, data traffic, or all traffic. The RNCselects an appropriate cell as the target cell of access or handover in accordance withthe traffic type and UE capability during RRC connection establishment, RAB assignment,handover, cell reselection, or channel transfer.

2-7



The RNC supports the variation of settings in different cells. For example, some cells areset to support only HSDPA services but not R99 services, meaning that only HS-DSCHscan be used for traffic bearing while DCHs cannot be used for traffic bearing.

The RNC using the HSUPA technology supports the load balancing of HSUPA trafficamong multiple carriers in a UMTS network or between a UMTS network and a GSMnetwork.

2.4 User Data TransmissionUser data transmission involves signalling data transmission and user data transmission,processing IUUP/RLC/MAC/FP. It implements the data ciphering, and flow control ofMac-C and Mac-hs, and provides users with end-to-end data transmission function.

Overview....................................................................................................................6-1Networking With Base Station ....................................................................................6-1Networking With Core Network...................................................................................6-4Networking With Radio Network Controller .................................................................6-4

6.1 OverviewThe ZXUR 9000 UMTS has good compatibility with the existing 2 G/3 G base stationequipment from operators, and supports to connect to 2 G/3 G base stations and 2 G/3G core networks through several transmission modes. Reasonable networking assists inthe long-term network planning and the reduction of networking costs.

6.2 Networking With Base StationThe networking between ZXUR 9000 UMTS and the base station supports the ATMtransmission, SDH transmission, IP transmission, or the hybrid transmission.

l The ATM STM-1 interface at the base station is available to the operator's ATMnetwork for accessing to ZXUR 9000 UMTS.

l In the SDH transmission network, the base station can be connected to ZXUR 9000UMTS over the narrowband E1/T1, and CSTM-1 interfaces.

l ZXUR 9000 UMTS can be interconnected and interchanged with the IP backbonenetwork. Selecting appropriate access mode and differentiating different VLANscan effectively separate broadcast storms from Ethernet. Meanwhile, setting abroadband network access server (BNAS) in the network is capable of implementingauthentication and security control.

l The hybrid networking, which is applicable to ZXUR 9000 UMTS and the base station,falls into IP network and conventional SDH transmission network based on sites, or theSDH network and IP backbone network based on CS and PS services respectively.

According to the network topology, star networking, chain networking, ring networking(requires supported transmission network), and hybrid networking are applicable to ZXUR9000 UMTS and the base station.

l In start networking, ZXUR 9000 UMTS is directly connected with each base stationwhich is a kind of end equipment. This networking mode is very simple and themaintenance and engineering are very convenient too. Because signal passes

6-1



through fewer intermediate links along the transmission path, the link reliability ismuch higher. Star networking is usually applied in dense-populated urban areas.

l Chain networking is usually applied in strip-shaped, sparse-populated areas, and alarge amount of transmission equipment can be saved. The chain networking modeis also applicable to one site with multiple base stations. Since signals go throughmore links, the line reliability is relatively poor.

In actual engineering networking, since the sites are generally sparse, the differencewith the basic networking mode is that transmission equipment is generally neededbetween ZXUR 9000 UMTS and base stations to serve the purpose of intermediateconnection. The common transmission media include: microwave, optical cable,HDSL cable, and coaxial cable.

l The ring networking mode involves two sets of links running in the active/standbymode. Every node on the ring has two upper-level nodes, which increases the linkreliability. In this case, when a site is damaged or a link fails, the lower-level nodescan select another link as the active link.

Note:

The ring networking between ZXUR 9000 UMTS and base stations is dependent upontransmission equipment.

l Hybrid networking is easily adaptable to the current transmission mode of theoperator. In early establishment of the network, hybrid networking makes the most ofthe established transmission network, thus saving the network cost and speeding thenetwork establishment for the operator to grasp business opportunity. With scatteredbase stations, hybrid networking supports multiple topologies, thus making networkestablishment flexible and simple.

6.2.1 Networking With 2G/3G Base StationsZXUR 9000 UMTS supports to connect with 2G and 3G base station equipmentsimultaneously. It connects with the 2G and 3G base station equipment through theAbis interface and the Iub interface respectively. The transmission media are applicableto such transmission network resources as E1, T1, SDH, and IP. Figure 6-1 shows thenetworking involving ZXUR 9000 UMTS, and 2G/3G base stations.

The transmission media are applicable to suchtransmission network resources as E1, T1, SDH, and IP. Figure 6-2 shows the networkinginvolving ZXUR 9000 UMTS and multi-mode base stations.

6.3 Networking With Core NetworkWhen networking with CN, the ZXUR 9000 UMTS connects with MSC and MGWthrough the Iu-CS interfaces, and connects with SGSN through the Iu-PS interfaces.The transmission protocols involve the ATM and IP protocols. The transmission mediaare applicable to the E1, T1, SDH, and IP transmission network resources. Figure 6-3illustrates the networking with CN.

9.1 Hardware Reliability DesignThe rack and service subracks all adopt dual power supplies, so that at leastdouble-channel cables are used inside the rack. The control plane boards adopt theactive/standby working mode, while the user plane boards adopt the load sharing workingmode. The interface boards adopt either the active/standby or the load sharing workingmode. Therefore, the faults of any individual hardware do not affect the normal operationof the system.

Board Backup Modes

To ensure reliability, the key boards of the ZXUR 9000 UMTS system provide the 1+1backup and load sharing modes.

l 1+1 backup

The two boards working in the active/standby mode operate at the same time andprocess the same service. The board in standby mode does not output serviceinformation.

When the board in active mode becomes faulty, the system immediately performsactive/standby switchover, which does not affect the system functions.

l Load sharing

The boards working in the load sharing mode backups the service data. That is, whenservices are running, related service data is allocated to the load sharing boards. Ifone of the boards is faulty, the system negotiates to rapidly allocate the service datato other load sharing boards, to ensure the normal running of services.

Backup Modes Supported by Boards

Table 9-1 describes the backup modes supported by ZXUR 9000 UMTS boards.

9.2 Clock Synchronization ReferenceThe system has several clock source outputs.Under self-synchronization mode, thelocal oscillator clock signal is applied. Under master/subordinate synchronization mode,the clock source can be the external synchronous BTS clock, GPS clock, or the linesynchronous clock extracted from any of the optical interface boards or trunk interfaceboards. The clock selects one phase-locked circuit from any of the appropriate clocksource and locks its phase. After that, synchronous clock needed by the system isgenerated, drived by the clock, and allocated to the resource shelves in the system andsubsystems.

The clock input source of the clock module involves BITS, local oscillator, line extractor,and GPS.

9.3 EMC DesignEMC design focuses on the rack, and the shielding and grounding of subracks. Subracksare designed with shielding levels. The cabinet is in a complete architecture form even itis not installed with shielding materials.

According to subracks' requirement of EMC electromagnetic shielding, the subrack surfaceis made plating treatment, to make the subrack conductive. The rack is designed withgrounding terminal that should be of reliable grounding and identification. The antistaticgrounding device, which is used for the subrack connecting with rack, is available to thesubrack.

Chapter 9 Reliability

9.4 Grounding and Security DesignGrounding of electronic equipment is for security and preventing interference. ZXUR 9000UMTS has built-in protective grounding cable, system grounding cable, and shieldedgrounding cable. The following requirements are met in design:

l Door-rack is of good electrostatic discharge means with grounding cable connectingdoors (front, rear, left, and right) and the rack.The rack has grounding busbar withobvious identification.

l Subrack-rack has good electrostatic discharge means. The rack is galvanized color-fully. The pole holes for installing subracks and the contacting part between the poleand the rack are secured with conductivity. The inside of subrack panel is also securedwith conductivity. Therefore, subracks have good electrostatic discharge means be-tween poles and the rack. The side beam of subrack is nickel plated, to ensure goodconductivity between the side beam and rack.

l The protective grounding of subracks is implemented through the connection ofsubrack side beam and rack, while the working ground and -48 V ground of subracksare connected to the rack busbar through cables, to connect with the ground busbarof the equipment room.

l The air filter which is added to the air intake at the rack bottom: it uses ABS plasticas the frame, with nylon net inside. The air filter is flexible. The door air filter: it usesmetal as the frame, with polyurethane second foaming plastic inside. Both types of airfilters can be reused after cleaning, and are easy for installation and disassembling.

l The cabinet is designed with unexposed and touchable sharp edge, to preventdamages to operation and maintenance personnel. Operation instruction is pastedon the cabinet door, to regulate installation and maintenance, and ensure security. Inaddition, warning signs are available to corresponding operation and maintenancepositions.

9.5 Software Reliability DesignThe system software adopts reliable design. All the system, except the external operationandmaintenance interfaces, has an internal communication network completely separatedfrom the outer network. Besides, the system is equipped with a built-in firewall to protectthe external O & M interfaces against attacks. At the same time, the O & M subsystemsupports high-security authentication design, which enables the authorization of differentlevels of operations to users.

The product has powerful fault tolerance, which can be illustrated by the following aspects:

l Automatic testing for user-defined configurations. Illegal or improper configuration willbe rejected, and the user will be prompted to make proper settings.

l Supports the backup of the key version or major data as the basis for rollback in thecase of failed loading of a version or relevant data.

l The Watchdog function can restart a board to resume operation when an error occursduring the software operation. Meanwhile, the black box records the runtime errorsfor further analysis.

9-3



l During the backup of hardware, the software can automatically test the faults occurringat ports, links, and other faults. If any fault is tested, the software automatically startor activate the standby unit to ensure proper system operation.
