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.

2.1.1 MCC：MCC is Mobile Country Code for 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

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.

2.1.7 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


6


to locate UE for CN.

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.


7


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 multi-

layer 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.

The meaning of each 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.

Adjust neighbor cells 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.

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 long-

time 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 meaning of each parameter is understandable, 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

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.

system to 2G system, besides neighbor cell needs to configured, GSM cell information shall also be

configured in WCDMA system, which is shown in the following table.

3 Radio Parameters Require to be Configured in GSM System in Mutual Operation between 2G

and 3G System

In mutual operation between 2G and 3G system, besides configuring GSM cell information in WCDMA

system, WCDMA cell information and neighbor cell information shall also be configured in GSM system

that requires cooperation with GSM equipment manufacturer. Provided parameters vary with manufacturers;
