2.1 RAN Reconfiguration Definition
RAN reconfiguration refers to the data reconfiguration in the functioning RAN. RAN
reconfiguration enables the RAN to provide services to more UEs or provide improved services
after the configuration is changed. The RAN consists of at least one RNC and one NodeB.
RAN reconfiguration is based on following reasons:
l Network optimization
Network optimization refers to adption and optimization to network during running course
based on system running data obtained by performance measurement or rounting test.
l System capacity expanding
System capacity expanding aims to serve much more terminal users by adding hardware
or change configuration on exsisting network.
The emphases of RAN reconfiguration is to introduce the data needed preparation and the
process of reconfiguration. The analysing course for network optimization data, the confirmation
course of the hardware in systerm expanding and the link quatity are ensured by specifical
network.
2.2 RAN Reconfiguration Tools
This describes the RAN reconfiguration tools. The tools include LMT and WCDMA
Configuration Management Express (CME) that can be used at either the RNC or the NodeB.
Table 2-1 describes the RAN (including RNC and NodeB) reconfiguration tools.
Table 2-1 RAN reconfiguration tools
NE ReconfigurationTool
Description
RNC LMT By using MML commands, you can configure data for
an RNC in either online or offline mode.
l In online mode, the configuration data is directly sent
to the host of the RNC, and the data takes effect
immediately. This mode applies to data
reconfiguration.
l In offline mode, you must restart the RNC host.
Then, the configuration takes effect. This mode
applies to RNC initial configuration.
For details about the reconfiguration process, refer to
the RAN Reconfiguration Guide.

NE ReconfigurationTool
Description
CME You can configure the data of an RNC on the CME.
l In integrated mode, the configuration data can besent to the RNC host through the M2000
immediately or at a specified time. This mode applies
to data reconfiguration.
l In standalone mode, export the configuration file
after the operation, and then load the configuration
file to the RNC host through the LMT or M2000. The
data takes effect. This mode applies to RNC initial
configuration.
For details about how to use the CME to perform RAN
reconfiguration, refer to the RAN Reconfiguration
Guide (CME-Based).
NodeB LMT By using MML commands, you can configure data for
the NodeB online. The configuration data takes effect
immediately. This mode applies to data
reconfiguration.
For details about the reconfiguration process, refer to
the RAN Reconfiguration Guide.
CME You can configure the data of a NodeB on the CME.
In integrated and standalone modes, export the
configuration file after the operation, and then load the
file to the NodeB host through the LMT or M2000 totake effect.
For details about how to use the CME to perform RAN
reconfiguration, refer to the RAN Reconfiguration
Guide (CME-Based).
2.3 RAN Reconfiguration Process
When reconfiguring the RAN data on the LMT, you must comply with the specific process to
minimize the impact on current services.
Context
During the RAN reconfiguration, note that:
l Unless otherwise stated, the RNC data has to be reconfigured online. In online mode, you
need not restart the host. This helps to minimize the impact on current services. When a
task can be performed only in offline mode, it is indicated at that particular task.
l For a NodeB, the configuration involves reconfiguration or initial configuration.
NOTE
The Huawei NodeB has different models. The board names and MML commands vary with the NodeB
model.

3.2 Setting the IP Address of the NodeB LMT PC
This describes how to set the IP address of the NodeB LMT PC. You must set a correct IP address
for the LMT PC before logging in to the NodeB.
Prerequisite
The TCP/IP protocol is configured on the LMT PC.
Context
Before you perform the maintenance, set the IP address for the LMT PC as follows:
l In local maintenance, IP addresses of the LMT PC and the NodeB local maintenance
channel are in the same network segment.
l In remote maintenance, you need to set the route from the LMT PC to the NodeB; IP 1 and
IP 2 are in the same network segment, as shown in Figure 3-1. IP 1 stands for the IP address
of the LMT PC. IP 2 stands for the IP address of the external network composed of the
entity directly connected to the LMT PC and the LAN where the LMT PC is located, for
example, the IP address of the RNC BAM external network.

6.2.6 Cell/Channel Activation and Deactivation
This describes cell activation, cell deactivation, channel activation, and channel deactivation.
6.2.7 Definition of Neighboring Cell
A neighboring cell is associated with a specific cell. There are three types of neighboring cell
for UMTS cells: intra-frequency neighboring cell, inter-frequency neighboring cell, and
neighboring GSM cell.
6.2.1 Definitions of Sector, Carrier, and Cell
A sector is the smallest radio coverage area unit, which is covered by one or more radio carriers.
Each radio carrier occupies a frequency. A sector and a carrier form a cell that is the smallest
serving unit for UE access.
Sectors are of two types: omnidirectional sector and directional sector. The omnidirectional
sector provides coverage for small traffic. It covers the 360º circle area with the omnidirectional
antenna in the center of the circle. As the traffic grows, the omnidirectional sector is split into
three or six directional sectors. The directional sectors are covered by directional antennas. For
a 3-sector cell, each of the three directional antennas covers a 120º sector area. For a 6-sector
cell, each of the six directional antennas covers a 60º sector area. In fact, the azimuth of the
antenna is greater than the theoretical value, and therefore there is overlap between the sectors.
Number of cells supported by a NodeB = number of sectors x number of carriers in each sector.
Figure 6-1 shows the typical 3 x 2 configuration. The whole circle area is split into three sectors:sector 0, sector 1, and sector 2. Each sector has two carriers, and each carrier forms a cell. There
are six cells in total.
Frequency multiplexing is allowed in a WCDMA system if different downlink primary
scrambling codes are used in neighboring cells of different sectors that use the same frequency.
The different downlink primary scrambling codes lower the interference between cells.
Figure 6-1 shows the relations between sector, frequency, and cell.

6.2.2 Definitions of Local Cell and Logical Cell
In the 3GPP, a service-providing cell is referred to as a local cell in implementation sense and
as a logical cell in logical resource management sense.
Local Cell
A local cell is a combination of physical resources, such as hardware resources and software
resources, in a cell of a NodeB. A local cell is related to the physical implementation of a device.
NodeBs from different vendors have different ways of providing physical resources for cells.Therefore, the concept of logical cell is proposed by the 3GPP to ensure that the RNC can control
the radio resources in certain cells through the standard Iub interface. These cells are carried on
NodeBs from different vendors.
Logical Cell
A logical cell is a standard logical model that helps the RNC control the radio resources in a
cell. The model is independent of local cell implementation and ensures that the Iub interface is
an open interface. For details about the logical cell model, refer to 6.2.3 Logical Cell Model.
The parameters of a local cell are configured at and managed by the NodeB. The parameters of
a logical cell are configured at and managed by the RNC. Each logical cell has a one-to-onerelationship with each local cell.

Cell RF Resources
The NodeB provides the physical RF resources of the cells. Figure 6-3 shows the physical RF
resources mapped onto the NodeB from the sector. Each sector uses one directional antenna.
Each directional antenna provides 2-way receive channels to enhance the receiving sensitivity,
and the two channels can work in mutual diversity mode.
l The RF module of distributed NodeB is RRU or PicoRRU (PRRU).
l The RF module of the macro NodeB is composed of the MAFU and MTRU. The MAFU
and MTRU are always in pairs.

Cell Resource PoolThe macro NodeB puts the UL/DL signal processing resources in the resource pool for the cells
to share. When you configure the cell, specify the type of the resource pool. The two types of
resource pool are as follows:
l GEN_POOL: UL/DL baseband resource pool that consists of the HBBI, HULP, and HDLP
boards. This type of resource pool is commonly used. You must specify the uplink baseband
resource group.
l GRP_POOL: UL/DL baseband resource pool that consists of the HBOI board in slot 15.
You need not specify the uplink baseband resource group.
Uplink baseband resource group. Uplink baseband resource group has the following features
and requirements:
l One uplink baseband resource group consists of one or more uplink processing units. One
uplink processing unit corresponds to one HBBI/HBOI/HULP board or one BBU module.
l The cells in one uplink baseband resource group share the uplink resources. Each uplink
baseband resource group processes signals of up to six cells in 2-way and enhanced 2-way
modes. Each uplink baseband resource group processes signals of up to three cells in 4-
way and economic 4-way modes.
l The softer handover can be performed between the cells in the same uplink baseband
resource group. You are advised to add the intra-frequency cells to the same group.
l The number of resource groups should be kept as small as possible. For example, for a 3 x
4 NodeB, you are advised to divide the resource pools into two groups with each groupsupporting six cells.

6.2.6 Cell/Channel Activation and Deactivation
This describes cell activation, cell deactivation, channel activation, and channel deactivation.
NOTE
l Before activating the HSDPA function of a cell, you need to run the ADD CELLHSDPA command
to add the HSDPA parameters of the cell.
l Before activating the HSUPA function of a cell, you need to run the ADD CELLHSUPA command
to add the HSUPA parameters of the cell.
l As an additional feature of a cell, the HSDPA function needs to be activated by running the ACT
CELLHSDPA command.
l As an additional feature of a cell, the HSUPA function needs to be activated by running the ACT
CELLHSUPA command.
Cell Activation
Before the logical cell is activated, the system checks whether the cell data in the database is
consistent and complete.
If... Then...
The cell data is consistent and
complete,
The cell is successfully activated, and the cell is in active
state. In this case,
l If the data transmission on the Iub interface is normal
and the NodeB works properly, the process to set up
the cell is triggered on the Iub interface, and the cell
on both the RNC and the NodeB will be in service
state.l If the data transmission on the Iub interface is
abnormal or the NodeB does not work properly, the
process to set up the cell is not triggered on the Iub
interface. Though the cell is in active state, it cannot
provide services.
The cell data is inconsistent or
incomplete,
The cell fails to be activated, and the cell is in deactivated
state.
Cell Deactivation
If the logical cell is not activated after configuration, the cell fails to be activated, or the logical
cell is deactivated, the logical cell is in deactivated state.
NOTE
Before deactivating the logical cell, you should perform the forced handover of UEs from the logical cell
and block the logical cell to avoid the impact on subscribers during deactivating the logical cell.
Deactivating a serving cell triggers the cell deletion process on the Iub interface. Then, the cell
is unable to provide services.
Deactivating a channel and deleting a channel are two different operations.
l
Deactivating a cell triggers the cell deletion process on the Iub interface, but still keeps thecell data in the database. You can set up the cell again by activating the cell.

l Deleting a cell deletes the cell data from the database permanently. In addition, this
operation triggers the cell deletion process on the Iub interface.
Channel Activation
After the PRACH or SCCPCH is configured at the RNC, the PRACH or SCCPCH channel is
in active state if the channel is successfully activated.
Before the channel is activated, the system checks whether the channel data in the database is
consistent and complete.
If... Then...
The channel data is consistent
and complete,
The channel is successfully activated, and the channel is in
active state. In this case,
l If the cell where the channel is located is in service state,
activating the channel can trigger the setup of common
transport channel on the Iub interface. Thus, the channel
is also in service state.
l If the cell where the channel is located is in deactivated
state, activating the channel does not trigger the setup of
common transport channel on the Iub interface. If the cell
is activated later, the process is triggered to set up the cell
and common transport channel on the Iub interface to
make them enter the service state at the same time.
The channel data is
inconsistent and incomplete,
The channel fails to be activated, and the channel is in
deactivated state.
Channel Deactivation
If the channel is not activated after configuration, the channel fails to be activated, or the channel
is deactivated, the channel is in deactivated state.
NOTE
If there is only one PRACH or SCCPCH in an active cell, or there are two SCCPCHs but the one carrying
the PCH is deactivated, you must deactivate the cell before deactivating the channel.
Deactivating a serving channel triggers the common transport channel deletion process on the
Iub interface. Then, the channel is unable to provide services.
Deactivating a channel and deleting a channel are two different operations.
l Deactivating a channel triggers the channel deletion process on the Iub interface, but still
keeps the channel data in the database. You can set up the channel again by activating the
channel.
l Deleting a channel deletes the channel data from the database permanently. In addition,
this operation triggers the channel deletion process on the Iub interface.

6.3 RAN Clock Synchronization Configuration
This describes how to configure RAN clock synchronization. The configuration involves the
RNC clock sources, RNC clock strata, switching policy of RNC clock sources, and switching
policy of NodeB clock sources.
6.3.1 RNC Clock SourcesThe RNC has the following clock sources: Building Integrated Timing Supply System (BITS)
clock, Global Positioning System (GPS) clock, line clock, and external 8 kHz clock.
6.3.2 RNC Clock Source Strata
The RNC clock source strata are classified into four strata, that is, strata 1 to 4, in descending
order by priority.
6.3.3 Switching Policy of RNC Clock Sources
The clock sources are classified into current clock sources and non-current clock sources. Based
on the switching policy, the system clock is fixed at the current clock source or switched to
another non-current clock source.
6.3.4 Switching Policy of NodeB Clock SourcesThe NodeB may have multiple clock sources, but it has only one working clock source at a time.
You need to set the clock source working mode to Free or Manual.
6.3.1 RNC Clock Sources
The RNC has the following clock sources: Building Integrated Timing Supply System (BITS)
clock, Global Positioning System (GPS) clock, line clock, and external 8 kHz clock.
BITS Clock
The BITS clock is of three types: 2 MHz, 2 Mbit/s, and 1.5 Mbit/s. The BITS clock has twoinput modes: BITS 1 and BITS 2. The RNC obtains the BITS timing signals through the timing
signal input ports on the GCUa/GCGa board.
NOTE
The 2 MHz and 2 Mbit/s timing signals are E1 timing signals, and the 1.5 Mbit/s timing signals are T1
timing signals.
GPS Clock
The GPS clock provides 1 Pulse Per Second (PPS) timing signals. The RNC obtains the GPS
timing signals from the GPS system. The GCGa board is configured with a GPS card, and the
RNC receives the GPS signals at the ANT port on the GCGa.

http://slidepdf.com/reader/full/ran-reconfiguration-guideran11001 94/103
NOTE
The GCUa board is not configured with a GPS card. Therefore, when the RNC is configured with the GCUa
instead of the GCGa, the GPS clock is unavailable to the RNC.
Line Clock
The line clock is an 8 kHz clock that the Iu interface board in the RSS subrack provides for the
GCUa/GCGa board through the backplane channels. The line clock has two input modes: line
1 and line 2.
External 8 kHz Clock
Through the COM1 port on the GCUa/GCGa board, the RNC obtains 8 kHz standard timing
signals in RS-422 level mode from an external device.
Local OscillatorIf the RNC fails to obtain any external clock, the RNC can obtain its working timing signals
from the local oscillator.
NOTE
The timing signals generated by the local oscillator, however, do not meet the requirements of NodeBs for
clock precision. Therefore, when the RNC uses such timing signals, the NodeBs fail to obtain the timing
signals that meet the precision requirements from the RNC.
6.3.2 RNC Clock Source Strata
The RNC clock source strata are classified into four strata, that is, strata 1 to 4, in descending
order by priority.
During RNC clock source configuration, adhere to the following principles:
l Clock sources and clock source priorities have a one-to-one correspondence.
l The LINE1_8KHZ and LINE2_8KHZ clock sources are locked at the interface board and
sent to the backplane. Each of the 8 KHz clocks can have only one clock source.
In practice, the RNC usually uses line clocks. The system can also use the BITS or GPS clock
in the equipment room if they are available.
6.3.3 Switching Policy of RNC Clock Sources
The clock sources are classified into current clock sources and non-current clock sources. Basedon the switching policy, the system clock is fixed at the current clock source or switched to
another non-current clock source.
Command: SET CLKMODE
l Manual mode
In manual mode, a clock source is specified as the current clock source. The system cannot
use another clock source even if this clock source fails.
l Automatic mode
In automatic mode, you do not need to specify a clock source as the current clock source.
The system automatically selects a clock source with the highest priority. For example, if the current clock source with the priority of PRI3 is faulty, the system selects a clock source

with the priority of PRI4. If the faulty clock source recovers, the system switches the clock
source to PRI3. If all the clock sources are faulty, the system is switched to the free-run
mode. When the clock sources recover, the system is switched to the AUTO mode.
6.3.4 Switching Policy of NodeB Clock SourcesThe NodeB may have multiple clock sources, but it has only one working clock source at a time.
You need to set the clock source working mode to Free or Manual.
l MANUAL
If the switching policy is set to Manual, the NodeB uses the clock source. If the clock source
is faulty, the NodeB works in free-run mode. When the clock source is recovered, the NodeB
reselects it.
l FREE
If the switching policy is set to Free, the NodeB clock works in free-run mode.
