5. Internal Use Only▲ 1 1.1 Overview Purpose of the Guide Initial radio parameters need to be 
configured and data need to be planned by engineers from Customer Service Department for the newly 
established or capacity expanded network before commissioning and debugging. The document mainly 
introduces 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 Reference

Department 2 Radio Parameter of WCDMA Newly-constructed Network Radio parameters mentioned 
here represent some parameters in each practical network that need to be set according to practical 
situation, such as network number, NodeB number, cell number, routing area code, etc.; some commonly 
used parameters such as cell handover parameter and reselection parameter can be generally set as default 
and won’t be described here. These configured parameters need to be set in OMC by engineers from 
Customer Service Department, some need to be set in NodeB, such as cell number. Because there are 
numerous 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 a 
detailed example and also a configuration template, including parameters need to be configured in 
WCDMA 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 that 
the parameters input in template mode for configuring are controlled by one RNC; if parameters are 
controlled by several RNC, they need to be configured for several times by the same configuration 
method. Table 1 Cell Parameter Description Parameter MCC MNC RncId NodebNo SectorId CId

uniquely identifying countries in which mobile subscriber (or system) is located; it is allocated 
internationally and the code for China is 460, while the code for other countries can be searched out on 
Google website. 2.1.2 MNC: MNC is Mobile Network Code for uniquely identifying a specific PLMN 
in a certain country (determined by MCC), it is provided by operators such as China Mobile and China 
Unicom. 2.1.3 RNCId: RNCId is for uniquely identifying RNC in a specific PLMN in one country 
(determined by MCC). If there is only one RNC, RNCId can be set randomly; its default value is 1. If the 
network dimension is so large that many RNC are used, then RNCId shall be set flexibly and 
differentiated 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 usually 
restricted by RNC capacity and practical network dimension. There will not be too many NodeB 
controlled by one RNC, so different value range can be used to identify different NodeB. If the site’s 
number shall be the same with that in GSM system, we use GSM numbering. NodeB is classified by 
phase, for instance, 1XXX represents phase one, 2XXX represents phase two, etc. NodeB number can also 
be used for differentiating RNC boundary, cities (for instance, 1XX represents city one, 2XX represents 
city two, etc.), site types (macro-site/micro-site, R99/HSDPA, etc.) as well as other features. 2.1.5 
SectorId: 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 used 
except in accordance with applicable agreements. 7 
8. Internal Use Only▲ clockwise from the North. Generally the site with one carrier and three sectors is in 
common use, so sector identity value is usually from 1 to 3. 2.1.6 Cid: Cell Identity’s scope is from 0 to 
65535, uniquely for identifying cell in RNC. When the network dimension is relatively small, Cid is 
represented as NodeB No + SectorId that limits the maximum NodeB number to 9999; but this isn’t 
compulsory, Cid can be set flexibly according to network actual situation. Generally the last digit of Cid is 
used to identify sector or carrier; as to 1C3S, the last digit of Cid is 1, 2, 3; as to 2C3S, the last digit of Cid 
is successively 4, 5, 6; as to 3C3S, the last digit of Cid is successively 7, 8, 9. What needs to be noticed is 
that 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 Cid

LAC: LAC is Location Area Code. For locating MS, each covering area in PLMN has been divided into 
several 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 traffic 
distribution. 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 the 
place 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 location 
area. It is used to locate UE for CN. This document contains proprietary information of ZTE Corporation 
and 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 belongs 
to BC domain. One cell has to own one SAC belongs to CS +PS domain, which is SACPC. The value of 
cell’s serving area code belongs to CS+PS domain is corresponding to RAC. 2.1.9 SACB: SACB is 
Serving Area Code belong to BC domain; its default value is 0. 2.1.10 SACBPre: SACB Configuration 
Tag represents whether SACB is configured; its present default value is 0. 2.1.11 RAC: RAC is Route 
Area Code that identifies a route area in location area in GSM-MAP PLMN for packet service. RAC is a 
part of RAI (RAI = PLMN-ID + LAC + RAC). RAC is set by operator through O&M in RNC. Now RAC 
value is usually the same with that of LAC, or refers to GPRS/EDGE value. We need to pay attention that 
site number shall not exceed its scope in route area. 2.1.12 LCId: LCId is Local Cell Identity. Local cell 
means resource of NodeB that can be configured as one certain cell; it is used for identifying 
corresponding cell resource when information exchange between CRNC and NodeB as well as when there 
is 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 cell 
establishment is failed. 2.1.13 LCGId: LCGId is Local Cell Group ID. Cells can share BP resource only 
when they are in the same local cell group. 2.1.14 TCell: TCell is used for defining the time delay of a 
cell 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 for 
establishing cell. The function of the parameter is to avoid inter-cell interference; for instance, SCH 
transmitting time varies with cells that facilitates UE to carry out cell synchronization and avoids 
interference. We suggest that TCell of geographically adjacent cells that belong to the same NodeB shall 
not be the same. Now the default settings are 256*0, 256*2 and 256*4 for 3 sectors successively. 2.1.15 
UUARFCH: UUARFCH is uplink utter radio frequency channel number, corresponding to the central 
frequency of cell uplink channel carrier. Its value is frequency*5. 2.1.16 DUARFCH: DUARFCH is 
downlink utter radio frequency channel number, corresponding to the central frequency of cell downlink 
channel carrier. Its value is frequency*5. This document contains proprietary information of ZTE 
Corporation 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 distinguishing 
cell; UTRAN system has totally 512 downlink primary scrambling codes. Cell primary scrambling code 
number is informed to NodeB through CELL SETUP REQUEST message when cell is established; it can 
not be modified in cell reconfiguration; if it has to be modified, we can only delete the cell and reset a new 
one. Scrambling code multiplexing distance is mainly considered in scrambling code planning; 
meanwhile, reservation of boundary area and indoor coverage shall also be noticed. Detailed planning 
methods please refer to WCDMA Cell Scrambling Code Planning Instruction (v1.0). Presently, there are 
two types of scrambling code planning. One is planning successively in 1, 2, 3 order. Another is planning 
with 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 sectors 
except one site owns 2 sectors, then the left third scrambling code isn’t used in the 2-sector site and the 
next scrambling code group is used in the next site. Generally, we use network planning and simulation 
software to plan scrambling code; set Atoll as an example, it can plan cell/site/site cluster separately, and 
enable different carriers to use same scrambling code, or even introduce neighbor cell relationship as a 
restraint 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. One 
cell can belong to at most 4 URAs; UE that stays in the cell can belong to different URAs, but UE in 
URA_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 multilayer 
structure to carry out cell planning, as to UE that moving in high speed, we can use macro-beehive with 
low priority to decrease cell reselection times. According to the same principle, URA update is lower than 
Cell update, so we can control when making UE stay in Cell_URA status through calculating UE’s cell 
update times; or counting by ourselves and make UE status change automatically from Cell_PCH to 
URA_PCH when cell reselection times exceeds a certain number during a period of time. Adjacent cells 
in different URAs can be configured to belong to many URAs for avoiding frequent URA update. 2.2 
Neighbor 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 input 
template of neighbor cell configuration, and these in sky-blue parts are ones require configuration. Notice: 
in neighbor cell configuration, cells are identified through Cid. Table 3 Parameter Description in Neighbor

parameter is understandable, so we mainly introduce method and principle of neighbor cell configuration. 
Principle of neighbor cell configuration mainly includes neighbor cell number, geographic topological 
structure, coverage interference, etc. Because the maximum number of neighbor cell list within a system is 
regulated as 31 in protocol, neighbor cell lists will be combined in soft handover status; we need to control 
neighbor cell number in configuration and try to minimize it as much as possible in the precondition of 
insuring the successful handover. Now all of the network planning and simulation software can be used 
for neighbor cell planning; for instance, the already existed neighbor cell relationship can be input in 
Atoll. But the accuracy of the present planning result of network planning and simulation software still 
needs to be improved; the situation of too many configured neighbor cells or missing out neighbor cell 
configuration happens, therefore we can use RNA to carry out manual checking and neighbor cell 
planning if the site’s scale isn’t large. Whether neighbor cell list setting is reasonable impacts handover 
between sites; the initial neighbor cell list formed in system design phase is set according to the following 
mode, 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 cells 
can be chosen as the present cell’s neighbor cell according to present cell’s coverage (shown in the 
following figure). The second layer cells on the same direction of the present sector are set as its neighbor 
cells, 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 cell 
whose scrambling codes are set as 4, 8 and 12; those cells formed in boldfaced broken lines are present 
sector’s neighbor cells. Pink ones are the first layer cells; blue ones are the second layer cells. This

according to each cell’s configured neighbor cell number as well as the situation whether cells are set as 
mutual neighbor cells. We try to realize neighbor cell mutual configuration; in principle, neighbor cell 
number 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, and 
secondly the second layer cells that are on the direction of the present cell. This document contains

14. Internal Use Only▲ 2.3 Neighbor Cell Configuration beyond the System When constructing network 
with other system, such as GSM system, on the coverage edge of WCDMA system, UE can continuously 
enjoy services through handover to GSM system due to GSM system’s longtime construction and perfect 
coverage. Therefore, neighbor cells among systems need to be configured for handover or reselection. The 
following table shows template parameters in neighbor cell configuration among systems. Table 5

what requires attention is that GSM cell is identified through LAC+CI. The method of neighbor cell 
configuration is generally the same with that in the system. There are two types of common mutual 
operations between 2G and 3G system. One is handover within This document contains proprietary 
information of ZTE Corporation and is not to be disclosed or used except in accordance with applicable 
agreements. 14 
15. Internal Use Only▲ GSM system on the coverage edge of WCDMA system; another is the whole 
WCDMA network is handed over in GSM system. When WCDMA network realizes continuous coverage, 
WCDMA system is only handed over in 2G system on its coverage edge, so only sites on the coverage 
edge 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 the 
priority to be chosen as neighbor cells; 3) Try not to configure congested GSM cells as neighbor cells as 
much as possible. When WCDMA network cannot realize continuous coverage, the mutual operation 
between the whole WCDMA network and 2G network shall be taken into account. The 2G neighbor cell 
configuration method in the whole WCDMA network is the same with WCDMA neighbor cell 
configuration method in WCDMA system, but the situation of neighbor cell traffic congestion shall also 
be considered at the same time. 2.4 Neighbor Cell Configuration Controlled by Other RNC Inter-RNC 
handover is hard handover; besides neighbor cell needs to be configured, corresponding cell information 
shall also be configured. Neighbor cell information table is shown as follows; parameter meaning is the 
same with that controlled by one RNC. Table 6 Neighbor Cell Information Table Controlled by One RNC

Internal Use Only▲ 1 1.1 Overview Purpose of the Guide Initial radio parameters need to be configured and data need to be planned by engineers from Customer Service Department for the newly established or capacity expanded network before commissioning and debugging. The document mainly introduces 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 Reference Manual for Newly Established Network Planning By Network Planning and Optimization Department Manual for WCDMA Cell Scrambling Code Planning (v1.0) By Network Planning and Optimization Department Guide for WCDMA Radio Parameter Optimization - A1 (v1.00) By Network Planning and Optimization Department Guide for WCDMA LAC Planning By Network Planning and Optimization Department 2 Radio Parameter of WCDMA Newly-constructed Network Radio parameters mentioned here represent some parameters in each practical network that need to be set according to practical situation, such as network number, NodeB number, cell number, routing area code, etc.; some commonly used parameters such as cell handover parameter and reselection parameter can be generally set as default and won’t be described here. These configured parameters need to be set in OMC by engineers from Customer Service Department, some need to be set in NodeB, such as cell number. Because there are numerous 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 a detailed example and also a configuration template, including parameters need to be configured in WCDMA 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 that the parameters input in template mode for configuring are controlled by one RNC; if parameters are controlled by several RNC, they need to be configured for several times by the same configuration method.

If there is only one RNC, RNCId can be set randomly; its default value is 1. If the network dimension is so large that many RNC are used, then RNCId shall be set flexibly and differentiated 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 usually restricted by RNC capacity and practical network dimension. There will not be too many NodeB controlled by one RNC, so different value range can be used to identify different NodeB. If the site’s number shall be the same with that in GSM system, we use GSM numbering. NodeB is classified by phase, for instance, 1XXX represents phase one, 2XXX represents phase two, etc. NodeB number can also be used for differentiating RNC boundary, cities (for instance, 1XX represents city one, 2XX represents city two, etc.), site types (macro-site/micro-site, R99/HSDPA, etc.) as well as other features. 2.1.5 SectorId: 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 used except in accordance with applicable agreements. 7 8. Internal Use Only▲ clockwise from the North. Generally the site with one carrier and three sectors is in common use, so sector identity value is usually from 1 to 3. 2.1.6 Cid: Cell Identity’s scope is from 0 to 65535, uniquely for identifying cell in RNC. When the network dimension is relatively small, Cid is represented as NodeB No + SectorId that limits the maximum NodeB number to 9999; but this isn’t compulsory, Cid can be set flexibly according to network actual situation. Generally the last digit of Cid is used to identify sector or carrier; as to 1C3S, the last digit of Cid is 1, 2, 3; as to 2C3S, the last digit of Cid is successively 4, 5, 6; as to 3C3S, the last digit of Cid is successively 7, 8, 9. What needs to be noticed is that 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 Cid Demonstration Site Number 101 101 101 101 101 101 101 101 101 102 102 102 102 103 104 104 2.1.7 Site Type 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 3C3S 2C2S 2C2S 2C2S 2C2S 1C1S 2C1S 2C1S 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 Cid Demonstration 1011 1012 1013 1014 1015 1016 1017 1018 1019 1021 1022 1024 1025 1031 1041 1044 LAC: LAC is Location Area Code. For locating MS, each covering area in PLMN has been divided into several 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 traffic distribution. Paging capacity determines the maximum cell number; too frequent frequency update may
  • 20. cause low call success rate and limits the minimum site number. LAC boundary shall be located in the place 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 location area. It is used to locate UE for CN. This document contains proprietary information of ZTE Corporation and 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 belongs to BC domain. One cell has to own one SAC belongs to CS +PS domain, which is SACPC. The value of cell’s serving area code belongs to CS+PS domain is corresponding to RAC. 2.1.9 SACB: SACB is Serving Area Code belong to BC domain; its default value is 0. 2.1.10 SACBPre: SACB Configuration Tag represents whether SACB is configured; its present default value is 0. 2.1.11 RAC: RAC is Route Area Code that identifies a route area in location area in GSM-MAP PLMN for packet service. RAC is a part of RAI (RAI = PLMN-ID + LAC + RAC). RAC is set by operator through O&M in RNC. Now RAC value is usually the same with that of LAC, or refers to GPRS/EDGE value. We need to pay attention that site number shall not exceed its scope in route area. 2.1.12 LCId: LCId is Local Cell Identity. Local cell means resource of NodeB that can be configured as one certain cell; it is used for identifying corresponding cell resource when information exchange between CRNC and NodeB as well as when there is 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 cell establishment is failed. 2.1.13 LCGId: LCGId is Local Cell Group ID. Cells can share BP resource only when they are in the same local cell group. 2.1.14 TCell: TCell is used for defining the time delay of a cell 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 for establishing cell. The function of the parameter is to avoid inter-cell interference; for instance, SCH transmitting time varies with cells that facilitates UE to carry out cell synchronization and avoids interference. We suggest that TCell of geographically adjacent cells that belong to the same NodeB shall not be the same. Now the default settings are 256*0, 256*2 and 256*4 for 3 sectors successively. 2.1.15 UUARFCH: UUARFCH is uplink utter radio frequency channel number, corresponding to the central frequency of cell uplink channel carrier. Its value is frequency*5. 2.1.16 DUARFCH: DUARFCH is downlink utter radio frequency channel number, corresponding to the central frequency of cell downlink channel carrier. Its value is frequency*5. This document contains proprietary information of ZTE Corporation 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 distinguishing cell; UTRAN system has totally 512 downlink primary scrambling codes. Cell primary scrambling code number is informed to NodeB through CELL SETUP REQUEST message when cell is established; it can not be modified in cell reconfiguration; if it has to be modified, we can only delete the cell and reset a new one. Scrambling code multiplexing distance is mainly considered in scrambling code planning; meanwhile, reservation of boundary area and indoor coverage shall also be noticed. Detailed planning methods please refer to WCDMA Cell Scrambling Code Planning Instruction (v1.0). Presently, there are two types of scrambling code planning. One is planning successively in 1, 2, 3 order. Another is planning with 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 sectors except one site owns 2 sectors, then the left third scrambling code isn’t used in the 2-sector site and the next scrambling code group is used in the next site. Generally, we use network planning and simulation software to plan scrambling code; set Atoll as an example, it can plan cell/site/site cluster separately, and enable different carriers to use same scrambling code, or even introduce neighbor cell relationship as a restraint 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. One cell can belong to at most 4 URAs; UE that stays in the cell can belong to different URAs, but UE in URA_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 multilayer structure to carry out cell planning, as to UE that moving in high speed, we can use macro-beehive with low priority to decrease cell reselection times. According to the same principle, URA update is lower than Cell update, so we can control when making UE stay in Cell_URA status through calculating UE’s cell update times; or counting by ourselves and make UE status change automatically from Cell_PCH to URA_PCH when cell reselection times exceeds a certain number during a period of time. Adjacent cells in different URAs can be configured to belong to many URAs for avoiding frequent URA update. 2.2 Neighbor Cell Configuration within the System For insuring UE’s mobility, handover can only be carried
  • 21. out when neighbor cells are configured in neighbor cell list by OMC. The following table is the input template of neighbor cell configuration, and these in sky-blue parts are ones require configuration.

Principle of neighbor cell configuration mainly includes neighbor cell number, geographic topological structure, coverage interference, etc. Because the maximum number of neighbor cell list within a system is regulated as 31 in protocol, neighbor cell lists will be combined in soft handover status; we need to control neighbor cell number in configuration and try to minimize it as much as possible in the precondition of insuring the successful handover. Now all of the network planning and simulation software can be used for neighbor cell planning; for instance, the already existed neighbor cell relationship can be input in Atoll. But the accuracy of the present planning result of network planning and simulation software still needs to be improved; the situation of too many configured neighbor cells or missing out neighbor cell configuration happens, therefore we can use RNA to carry out manual checking and neighbor cell planning if the site’s scale isn’t large. Whether neighbor cell list setting is reasonable impacts handover between sites; the initial neighbor cell list formed in system design phase is set according to the following mode, 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 cells can be chosen as the present cell’s neighbor cell according to present cell’s coverage (shown in the following figure). The second layer cells on the same direction of the present sector are set as its neighbor cells, 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 cell whose scrambling codes are set as 4, 8 and 12; those cells formed in boldfaced broken lines are present sector’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 cell number shall not exceed 18, neighbor cell mutual configuration rate has to be higher than 90%. The

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

The method of neighbor cell configuration is generally the same with that in the system. There are two types of common mutual operations between 2G and 3G system. One is handover within This document contains proprietary information of ZTE Corporation and is not to be disclosed or used except in accordance with applicable agreements. 14 15. Internal Use Only▲ GSM system on the coverage edge of WCDMA system; another is the whole WCDMA network is handed over in GSM system. When WCDMA network realizes continuous coverage, WCDMA system is only handed over in 2G system on its coverage edge, so only sites on the coverage edge 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 the priority to be chosen as neighbor cells; 3) Try not to configure congested GSM cells as neighbor cells as much as possible. When WCDMA network cannot realize continuous coverage, the mutual operation between the whole WCDMA network and 2G network shall be taken into account. The 2G neighbor cell configuration method in the whole WCDMA network is the same with WCDMA neighbor cell configuration method in WCDMA system, but the situation of neighbor cell traffic congestion shall also be considered at the same time. 2.4 Neighbor Cell Configuration Controlled by Other RNC Inter-RNC handover is hard handover; besides neighbor cell needs to be configured, corresponding cell information shall also be configured.
