5. Internal Use Only▲ 1 1.1 Overview Purpose of the Guide Initial radio parameters need to beconfigured and data need to be planned by engineers from Customer Service Department for the newlyestablished or capacity expanded network before commissioning and debugging. The document mainlyintroduces detailed principles and methods for radio parameters planning in newly established network,including cell’s basic information, such as cell’s ID, scrambling codes, neighbor cells, etc. 1.2 ReferenceManual for Newly Established Network Planning By Network Planning and Optimization DepartmentManual for WCDMA Cell Scrambling Code Planning (v1.0) By Network Planning and OptimizationDepartment Guide for WCDMA Radio Parameter Optimization - A1 (v1.00) By Network Planning andOptimization Department Guide for WCDMA LAC Planning By Network Planning and OptimizationDepartment 2 Radio Parameter of WCDMA Newly-constructed Network Radio parameters mentionedhere represent some parameters in each practical network that need to be set according to practicalsituation, such as network number, NodeB number, cell number, routing area code, etc.; some commonlyused parameters such as cell handover parameter and reselection parameter can be generally set as defaultand won’t be described here. These configured parameters need to be set in OMC by engineers fromCustomer Service Department, some need to be set in NodeB, such as cell number. Because there arenumerous data in large networks, data batch input can be realized in OMC for convenient configuration;each parameter owns input template. 2.1 Cell Radio Parameters Controlled by One RNC Attachment 1 is adetailed example and also a configuration template, including parameters need to be configured inWCDMA system. All cell radio parameters that need to be configured are listed in the following table,mainly in sky-blue part, which will be introduced one by one as follows. What need to be noticed is thatthe parameters input in template mode for configuring are controlled by one RNC; if parameters arecontrolled by several RNC, they need to be configured for several times by the same configurationmethod.

If there is only one RNC, RNCId can be set randomly; its default value is 1. If thenetwork dimension is so large that many RNC are used, then RNCId shall be set flexibly anddifferentiated by different construction period, different cities, different NodeB model (R99/HSDPA), etc.2.1.4 NodeB No： NODEB number is valid only to RNC; its value is from 0 to 65535 and is usuallyrestricted by RNC capacity and practical network dimension. There will not be too many NodeBcontrolled by one RNC, so different value range can be used to identify different NodeB. If the site’snumber shall be the same with that in GSM system, we use GSM numbering. NodeB is classified byphase, for instance, 1XXX represents phase one, 2XXX represents phase two, etc. NodeB number can alsobe used for differentiating RNC boundary, cities (for instance, 1XX represents city one, 2XX representscity two, etc.), site types (macro-site/micro-site, R99/HSDPA, etc.) as well as other features. 2.1.5SectorId： Sector Identity is only valid in Node B; its value scope is from 1 to 6. Sectors are named 1, 2,3 This document contains proprietary information of ZTE Corporation and is not to be disclosed or usedexcept in accordance with applicable agreements. 7

8. Internal Use Only▲ clockwise from the North. Generally the site with one carrier and three sectors is incommon use, so sector identity value is usually from 1 to 3. 2.1.6 Cid： Cell Identity’s scope is from 0 to65535, uniquely for identifying cell in RNC. When the network dimension is relatively small, Cid isrepresented as NodeB No ＋ SectorId that limits the maximum NodeB number to 9999; but this isn’tcompulsory, Cid can be set flexibly according to network actual situation. Generally the last digit of Cid isused to identify sector or carrier; as to 1C3S, the last digit of Cid is 1, 2, 3; as to 2C3S, the last digit of Cidis successively 4, 5, 6; as to 3C3S, the last digit of Cid is successively 7, 8, 9. What needs to be noticed isthat when site is omni-site or owns 2 sectors, the left ID in the same group (3 identities comprise a group)will be abandoned, and new cell will be identified again, the demonstration is as follows. Table 2 CidDemonstration Site Number 101 101 101 101 101 101 101 101 101 102 102 102 102 103 104 104 2.1.7Site Type 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 2C2S 2C2S 2C2S 2C2S 1C1S 2C1S2C1S Sector Number 1 2 3 1 2 3 1 2 3 1 2 1 2 1 1 1 Carrier Number 1 1 1 2 2 2 3 3 3 1 1 2 2 1 1 2 CidDemonstration 1011 1012 1013 1014 1015 1016 1017 1018 1019 1021 1022 1024 1025 1031 1041 1044LAC： LAC is Location Area Code. For locating MS, each covering area in PLMN has been divided intoseveral location areas; location area code is to identify different location areas. LAC is a part of LAI (LAI= MCC + MNC + LAC). LAI is Location Area Identity. One location area is composed by several cells.Cell number set in location area is mainly determined by paging capacity, frequency update and trafficdistribution. Paging capacity determines the maximum cell number; too frequent frequency update may

cause low call success rate and limits the minimum site number. LAC boundary shall be located in theplace where traffic is low. Detailed LAC planning please refer to WCDMA LAC Planning Instruction.2.1.8 SACPC： SAC is Serving Area Code, uniquely identifies one cell or several cells in one locationarea. It is used to locate UE for CN. This document contains proprietary information of ZTE Corporationand is not to be disclosed or used except in accordance with applicable agreements. 8

9. Internal Use Only▲ One cell has one or two SAC, one belongs to CS +PS domain, and another belongsto BC domain. One cell has to own one SAC belongs to CS +PS domain, which is SACPC. The value ofcell’s serving area code belongs to CS+PS domain is corresponding to RAC. 2.1.9 SACB： SACB isServing Area Code belong to BC domain; its default value is 0. 2.1.10 SACBPre： SACB ConfigurationTag represents whether SACB is configured; its present default value is 0. 2.1.11 RAC： RAC is RouteArea Code that identifies a route area in location area in GSM-MAP PLMN for packet service. RAC is apart of RAI (RAI = PLMN-ID + LAC + RAC). RAC is set by operator through O&M in RNC. Now RACvalue is usually the same with that of LAC, or refers to GPRS/EDGE value. We need to pay attention thatsite number shall not exceed its scope in route area. 2.1.12 LCId： LCId is Local Cell Identity. Local cellmeans resource of NodeB that can be configured as one certain cell; it is used for identifyingcorresponding cell resource when information exchange between CRNC and NodeB as well as when thereis no certain cell has been established. Notice: local cell identity has to be confirmed according to NodeB,the value of LCId has to be the same with the value of established logical cell identity, and otherwise cellestablishment is failed. 2.1.13 LCGId： LCGId is Local Cell Group ID. Cells can share BP resource onlywhen they are in the same local cell group. 2.1.14 TCell： TCell is used for defining the time delay of acell of a NodeB relative to the NodeB BFN. It determines the time delay between start time of cell SCH,CPICH, downlink PSC and BFN. The parameter is mainly used in Cell setup Request message forestablishing cell. The function of the parameter is to avoid inter-cell interference; for instance, SCHtransmitting time varies with cells that facilitates UE to carry out cell synchronization and avoidsinterference. We suggest that TCell of geographically adjacent cells that belong to the same NodeB shallnot be the same. Now the default settings are 256*0, 256*2 and 256*4 for 3 sectors successively. 2.1.15UUARFCH： UUARFCH is uplink utter radio frequency channel number, corresponding to the centralfrequency of cell uplink channel carrier. Its value is frequency*5. 2.1.16 DUARFCH： DUARFCH isdownlink utter radio frequency channel number, corresponding to the central frequency of cell downlinkchannel carrier. Its value is frequency*5. This document contains proprietary information of ZTECorporation and is not to be disclosed or used except in accordance with applicable agreements. 9

10. Internal Use Only▲ 2.1.17 PrimscraCode： Cell primary scrambling code is used for distinguishingcell; UTRAN system has totally 512 downlink primary scrambling codes. Cell primary scrambling codenumber is informed to NodeB through CELL SETUP REQUEST message when cell is established; it cannot be modified in cell reconfiguration; if it has to be modified, we can only delete the cell and reset a newone. Scrambling code multiplexing distance is mainly considered in scrambling code planning;meanwhile, reservation of boundary area and indoor coverage shall also be noticed. Detailed planningmethods please refer to WCDMA Cell Scrambling Code Planning Instruction (v1.0). Presently, there aretwo types of scrambling code planning. One is planning successively in 1, 2, 3 order. Another is planningwith the interval of 8. If customer hasn’t chosen which type of planning, we use the successive planning.Three scrambling codes are set as a group. For instance, if all of the surrounding sites have 3 sectorsexcept one site owns 2 sectors, then the left third scrambling code isn’t used in the 2-sector site and thenext scrambling code group is used in the next site. Generally, we use network planning and simulationsoftware to plan scrambling code; set Atoll as an example, it can plan cell/site/site cluster separately, andenable different carriers to use same scrambling code, or even introduce neighbor cell relationship as arestraint condition. The detailed operation please refers to related instructions. 2.1.18 URAnum：

URAnum is the number of UTRAN registration area, also the number of URA that cells belong to. Onecell can belong to at most 4 URAs; UE that stays in the cell can belong to different URAs, but UE inURA_PCH status can only belong to one of the URAs. The default value of URAnum is 1. 2.1.19 URA：

URA is UTRAN Registration Area, which is for avoiding too frequent signaling; when using multilayerstructure to carry out cell planning, as to UE that moving in high speed, we can use macro-beehive withlow priority to decrease cell reselection times. According to the same principle, URA update is lower thanCell update, so we can control when making UE stay in Cell_URA status through calculating UE’s cellupdate times; or counting by ourselves and make UE status change automatically from Cell_PCH toURA_PCH when cell reselection times exceeds a certain number during a period of time. Adjacent cellsin different URAs can be configured to belong to many URAs for avoiding frequent URA update. 2.2Neighbor Cell Configuration within the System For insuring UE’s mobility, handover can only be carried

out when neighbor cells are configured in neighbor cell list by OMC. The following table is the inputtemplate of neighbor cell configuration, and these in sky-blue parts are ones require configuration. Notice:in neighbor cell configuration, cells are identified through Cid.

Now all of the network planning and simulation software can be usedfor neighbor cell planning; for instance, the already existed neighbor cell relationship can be input inAtoll. But the accuracy of the present planning result of network planning and simulation software stillneeds to be improved; the situation of too many configured neighbor cells or missing out neighbor cellconfiguration happens, therefore we can use RNA to carry out manual checking and neighbor cellplanning if the site’s scale isn’t large. Whether neighbor cell list setting is reasonable impacts handoverbetween sites; the initial neighbor cell list formed in system design phase is set according to the followingmode, then neighbor cell list will be adjusted according to handover times after system is commissioned.Cells of one same site have to be set as each other’s neighbor cell; the first layer and the second layer cellscan be chosen as the present cell’s neighbor cell according to present cell’s coverage (shown in thefollowing figure). The second layer cells on the same direction of the present sector are set as its neighborcells, the first layer cells on the opposite direction of the present sector are also set as its neighbor cells.The following is an example of neighbor cell setting shown in figure 1. The red one is the present cellwhose scrambling codes are set as 4, 8 and 12; those cells formed in boldfaced broken lines are presentsector’s neighbor cells. Pink ones are the first layer cells; blue ones are the second layer cells.

We try to realize neighbor cell mutual configuration; in principle, neighbor cellnumber shall not exceed 18, neighbor cell mutual configuration rate has to be higher than 90%. The

adjustment order is firstly the second layer cells that aren’t on the direction of the present cell, andsecondly the second layer cells that are on the direction of the present cell.

14. Internal Use Only▲ 2.3 Neighbor Cell Configuration beyond the System When constructing networkwith other system, such as GSM system, on the coverage edge of WCDMA system, UE can continuouslyenjoy services through handover to GSM system due to GSM system’s longtime construction and perfectcoverage. Therefore, neighbor cells among systems need to be configured for handover or reselection. Thefollowing table shows template parameters in neighbor cell configuration among systems.

The method of neighbor cellconfiguration is generally the same with that in the system. There are two types of common mutualoperations between 2G and 3G system. One is handover within This document contains proprietaryinformation of ZTE Corporation and is not to be disclosed or used except in accordance with applicableagreements. 14

When WCDMA network realizes continuous coverage,WCDMA system is only handed over in 2G system on its coverage edge, so only sites on the coverageedge need to be configured with neighbor cells. The following principles are mainly taken into account.1） Co-sited cells with the same direction are configured as neighbor cells; 2） GSM900 cells own thepriority to be chosen as neighbor cells; 3） Try not to configure congested GSM cells as neighbor cells asmuch as possible. When WCDMA network cannot realize continuous coverage, the mutual operationbetween the whole WCDMA network and 2G network shall be taken into account. The 2G neighbor cellconfiguration method in the whole WCDMA network is the same with WCDMA neighbor cellconfiguration method in WCDMA system, but the situation of neighbor cell traffic congestion shall alsobe considered at the same time. 2.4 Neighbor Cell Configuration Controlled by Other RNC Inter-RNChandover is hard handover; besides neighbor cell needs to be configured, corresponding cell informationshall also be configured.
