INTRODUCTION
The present document explains the Cell Design Data (CDD) that must be
provided for each cell in an Ericsson GSM system, R10. This data is loaded in
the corresponding BSC by means of a Data Transcript file.
When a new Ericsson GSM system is built or when new cells are added or
changed in an existing Ericsson GSM system, the cell planner provides the
operator with a document for each cell containing data for the insertion of the
cell in the radio network. The data from all such documents is then converted
into a data transcript tape and loaded into the corresponding BSC.
A data transcript tape contains not only CDD information but also other data
needed for the complete configuration of the BSC and its BTSs. A description
of such information is out of the scope of this document.
In addition to the above-mentioned BSC cell parameters, some of the radio
related MSC parameters and exchange properties are included in this
document. These parameters are included in order to present a more complete
picture of the parameters that influence the design and evaluation of a radio
network.
Note: The MSC parameters are only defined for Ericsson Mobile Services
Switching Centres. These parameters may have another name or may not exist
at all in MSC’s manufactured by others than Ericsson.
This document gives references to GSM Recommendations.
This document provides short descriptions of Ericsson’s GSM system R10
parameters. For a full understanding of each of them, it is essential to study the
description of each particular feature. It should be noted that the availability of
a feature could depend on commercial agreements. Due to this it is possible
that certain parameters are not supported by an exchange.
The topics where GSM 800, GSM 900, GSM 1800 and GSM 1900 differ are
indicated.
This document assumes that the reader is acquainted with the channel structure
for GSM 800, GSM 900, GSM 1800 and GSM 1900, the TDMA concept and
the locating algorithm for Ericsson’s GSM systems.

1.1
CDD structure
The parameters in this document are organised according to radio network
features. The aim with this structure is to facilitate a more feature oriented cell
planning and network optimisation.
In each radio network feature section, the parameters are grouped into subsections defined by the network entity where the parameter is defined. This is
described more elaborately in section 1.2.
The CDD is also arranged in a structure that corresponds to the subcell
structure shown in figure 1. Therefore some parameters appear in more than
one part of the CDD.

Channel
group
The subcell structure supported by Ericsson’s GSM system.
A subcell is a set of channels that share some specific characteristics. An
overlaid subcell serves a smaller part of the area of an underlaid subcell.
A cell always has an underlaid (UL) subcell, whereas the overlaid (OL) subcell
is optional. A subcell structure exists when there is an overlaid subcell defined.
The notation “cell/subcell data” (see section 1.2) is used in order to clarify that
these parameters may be defined per subcell.
Each subcell is divided into channel groups, which include a subset of the
frequencies defined for a cell. A channel group can not be shared between
different subcells. One frequency can be defined in only one channel group
within the cell.
1.2
Conventions
In this section, rules and conventions for the parameter section in the CDD
document are issued.
“The parameter is /valid for/set per/ XXXX”

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
Comments:
Base Station output power in dBm for the BCCH RF channel
number.
The BTS can transmit with different power levels on the
frequency that carries the BCCH and on the frequencies that do
not carry it. The power is specified at the Power Amplifier (PA)
output, i.e. immediately after the transmitter unit and before the
combiner.
For RBS 200 the following is valid:
GSM 900:
GSM 1800:
31 to 47 dBm, odd values only
33 to 45 dBm, odd values only.
For RBS 2000 macro the following is valid:
GSM 800:
GSM 900:
GSM 1800:
GSM 1900:
35 to 47, 491), 512) dBm, odd values only
35 to 47, 491), 512) dBm, odd values only
33 to 45, 471), 492) dBm, odd values only
33 to 45, 471), 492) dBm, odd values only.
Note: For GSM 900 - TRU: KRC 131 47/01, the range is 31 to
43 dBm. If one or more GSM TRU type KRC 131 47/01 is used
within one cell the maximum output power for that cell shall be
limited to 43 dBm. To ensure that, the parameter MPWR (see
page 187) shall be set to 43 dBm for all TXs on that cell.
For RBS 2000 micro the following is valid:
GSM 800 (2308 only):21 to 33, 351) dBm, odd values only
GSM 900:
21 to 33, 351) dBm, odd values only
GSM 1800:
21 to 33, 351) dBm, odd values only
GSM 1900:
21 to 33, 351) dBm, odd values only.
For RBS 2401 indoor the following is valid:
GSM 900:
GSM 1800:
GSM 1900:
1)
7 to 19 dBm, odd values only
9 to 21 dBm, odd values only
9 to 21 dBm, odd values only.
Software Power Boost (not applicable for RBS 2401):
The feature Software Power Boost is activated by setting
BSPWRB to a special value that is 2 dB higher than the
maximum possible power at the PA output. TX diversity is used
and each TX supporting the master-slave configuration is
configured. A BTS with filter combiner does not support
Sofware Power Boost.
2)
Transmitter Coherent Combining:
The feature Transmitter Coherent Combining (TCC) is activated
by setting BSPWRB to a special value that is 4 dB higher than
the maximum possible power at the PA output. TCC is
applicable to RBS 2106, 2206 and 2207 only.

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
O&M:
If the cell is an internal cell, the parameter is only allowed to be
changed in cell state HALTED.
Comments:
CGI (Cell Global Identity) is the global identity of the cell in the
whole system. It is composed of four different parameters:
MCC
Mobile Country Code,
MNC
Mobile Network Code identifying the PLMN
(Public Land Mobile Network, i.e. the operator),
LAC
Location Area Code,
CI
Cell Identity within the location area.
CGI is sent to the mobile station (MS) as a part of the system
information message (GSM Rec. 04.08). The combination
MCC-MNC-LAC is also known as the location area identity
(LAI).
BSIC
Type:
NCC-BCC
Range:
NCC: 0 to 7 (Network Colour Code).
BCC: 0 to 7 (Base station Colour Code)
Unit:
–
Default:
–
Command:
RLDEC, RLDEP
O&M:
If the cell is an internal cell, the parameter is only allowed to be
changed in cell state HALTED.
Comments:
BSIC (Base Station Identity Code) is composed of two entities:
NCC
Network Colour Code.
BCC
Base station Colour Code,
BSIC is defined on a per cell basis and it is sent on the logical
synchronisation channel (SCH) on the BCCH frequency.
GSM 03.03, Annex A, assigns one NCC value "n" to each
European country "to ensure that the same NCC is not used in
the adjacent PLMNs". A second operator in a given country
would use the NCC value "n+4".
When an MS reports the results of the measurements made on
the serving cell and the neighbouring cells, it indicates
(GSM 04.08, section 10.5.2.20):
The measured signal levels on the serving cell.
The measured levels, the BSIC and the BCCH frequency of the
neighbouring cells.
90/1553-HSC 103 12/4 Uen Rev PE1 2004-05-26
11(214)
RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
Only measurements from cells with allowed NCC are reported
(see section 0).
The colour code NCC is then used to discriminate cells that use
the same frequency. Though mainly intended for the purpose of
differentiating PLMNs, it also serves to distinguish cells within
one PLMN that use the same frequency provided they have been
assigned different NCC. If there are two operators in a country,
they can use more than two PLMN colour codes each one,
provided that in border areas only the values "n" and "n+4" are
used.
What is stated here should be considered as general guidelines.
Of course any type of NCC assignment must be decided by
agreements between operators and countries.
Regarding the protection against co-channel interference, the
MS reports the BCC value so that the BSC can distinguish
among different cells transmitting on the same frequency. For
this purpose the BCC must be allocated as wisely as possible. If
frequency reuse clusters are used then it is recommended that all
BTSs in a given cluster use the same BCC. In this way the reuse
distance of a certain BCC can be maximised according to the
frequency reuse distance.
Note that only 8 different values (BCC: 0 to 7) are used for the
purpose of recognising co-channel interference.

According to the GSM 800 recommendations the channels are
numbered as follows:
fl(n) = 824.2 + 0.2*(n−128) in MHz, where n (Absolute Radio
Frequency Channel Number, ARFCN) goes from 128 to 251 and
fl is a frequency in the lower band, BTS receiver.
fu(n) = fl(n) + 45 in MHz, where n goes from 128 to 251 and fu is
a frequency in the upper band, BTS transmitter.
According to the GSM 900 recommendations the channels are
numbered as follows:
fl(n) = 890.2 + 0.2*(n−1) in MHz, where n (Absolute Radio
Frequency Channel Number, ARFCN) goes from 1 to 124 and fl
is a frequency in the lower band, BTS receiver.
fu(n) = fl(n) + 45 in MHz, where n goes from 1 to 124 and fu is a
frequency in the upper band, BTS transmitter.
According to the GSM 1800 recommendations the channels are
numbered as follows:
fl(n) = 1710.2 + 0.2*(n−512) in MHz, where n (Absolute Radio
Frequency Channel Number, ARFCN) goes from 512 to 885 and
fl is a frequency in the lower band, BTS receiver.
fu(n) = fl(n) + 95 in MHz, where n goes from 512 to 885 and fu is
a frequency in the upper band, BTS transmitter.
According to the GSM 1900 recommendations the channels are
numbered as follows:
fl(n) = 1850.2 + 0.2*(n−512) in MHz, where n (Absolute Radio
Frequency Channel Number, ARFCN) goes from 512 to 810 and
fl is a frequency in the lower band, BTS receiver.

COMB
indicates that the cell has a combined BCCH and
SDCCH/4 (see section 0).
COMBC
indicates that the cell has a combined BCCH and
SDCCH/4 with a CBCH subchannel.
NCOMB
indicates that the cell does not have any type of
combined BCCH and SDCCH/4.
The BCCH is always allocated to time slot number 0 (TN0) in
the defined ARFCN.
The CBCH is used for transmission of the messages when the
function Short Messages Service Cell Broadcast (SMSCB) is
activated in the cell. SMSCB enables the operator to submit
short messages for broadcasting to a specific area within the
PLMN.

Comments:
Number of reserved access grant blocks.
Number of CCCH blocks reserved for the access grant channel.
The remaining CCCH blocks are used for the paging channel.
In each downlink non-combined SDCCH 51 frames multiframe
there are 9 different CCCH blocks and in the combined
BCCH/SDCCH there are 3 different blocks. They can be used
to:
• Send paging messages, i.e. used as a Paging Channel.
• Send access granted messages, i.e. used as an Access Grant
Channel.
After an MS tunes to the BCCH/CCCH channel and decodes the
System Information, it performs an evaluation that, taking into
account the MS's own IMSI (International Mobile Station
Identity) number, determines to which particular CCCH block in
the physical channel it should listen (GSM 05.02). Every CCCH
in the physical channel (Paging Subchannel) sends paging
messages to a certain group of MSs that are called its paging
group. The reason for the existence of such paging groups is that
14(214)
90/1553-HSC 103 12/4 Uen Rev PE1 2004-05-26
RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
the MSs can save batteries because it only needs to listen to its
own Paging Subchannel messages.
The physical channel (Paging Subchannel) sends paging
messages to a certain group of MSs. As mentioned before these
very same CCCH blocks are also used to send Access Grant
messages to the MSs, i.e. to answer a Random Access message
that an MS wanting to access the system has sent to the system.
The structure of the BCCH regarding Paging messages and
Access Grant messages can be controlled by the two parameters
AGBLK and MFRMS.
AGBLK tells how many of the CCCH blocks that should be
reserved for the Access Grant messages. In Ericsson’s GSM
system, Access Grant messages are given priority over Paging
messages. Together with MFRMS, AGBLK indicates how
many paging groups there will be.
With a non-combined BCCH and AGBLK = 1, there are 8
CCCH blocks in each multiframe. This means that it is possible
to have 16 to 72 different Paging Subchannels, i.e. Paging
Groups. (Since MFRMS can take values between 2 and 9.)
With a combined BCCH/SDCCH and AGBLK = 1, there are 2
CCCH blocks in each multiframe. In this case it is possible to
have 4 to 18 different Paging Groups.
Note 1:
AGBLK must not be 0 when SI 7 and 8 have to be sent or when
short message service cell broadcast (SMSCB) is in use on a cell
not using combined BCCH and SDCCH/4 (GSM 05.02).
Note 2:
Only AGBLK = 0 and 1 is supported by the RBS 200 and RBS
2000 series BTS.

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
MFRMS is also used by the MS to determine downlink
signalling failure in idle mode (GSM 05.08). The downlink
signalling failure criterion is based on the downlink signalling
failure counter DSC. When the MS camps on a cell, DSC shall
be initialised to a value equal to the nearest integer to 90/N
where N is the MFRMS parameter for that cell. Thereafter,
whenever the MS attempts to decode a message in its paging
subchannel; if a message is successfully decoded DSC is
increased by 1, (however never beyond the nearest integer to
90/N), otherwise DSC is decreased by 4. When DSC reaches 0,

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
A maximum of 31 DCHNO per channel group can be defined
except for channel group 0, which allows only 30 DCHNO.
This is because one RF channel has to be reserved for the BCCH
that is defined by BCCHNO.
A channel group may consist of frequencies from different GSM
900 bands with one restriction. If the BCCH frequency is
defined in the P-band other DCHNO are only allowed in the Pband and not in the G1-band.

Required number of SDCCH/8.
Call set up, location updating and SMS are using the SDCCH
channel. The system supports four types of combination for
SDCCH channels (see also 0):
• SDCCH/4: The SDCCH is combined with the BCCH in time
slot 0 on the BCCH carrier. This SDCCH configuration
provides 4 subchannels for signalling. Only one SDCCH/4
can be defined for each cell. (BCCHTYPE = COMB).
• SDCCH/4 including CBCH: One subchannel is replaced by
a CBCH. This SDCCH/4 configuration provides 3
subchannels for signalling and one for transmission of
47SMSCB messages. (BCCHTYPE = COMBC).
• SDCCH/8: This SDCCH configuration provides 8
subchannels for signalling (BCCHTYPE = NCOMB,
CBCH = NO).
• SDCCH/8 including CBCH: One subchannel is replaced by
a CBCH. This SDCCH/8 configuration provides 7
subchannels for signalling and one for transmission of
SMSCB messages (BCCHTYPE = NCOMB, CBCH =
YES).
Up to 32 SDCCH/8 can be specified per cell. This number is
reduced by one if an SDCCH/4 is defined for the cell.
The number of SDCCH/8s in a channel group is limited to a
maximum equal to:
• the number of TRXs in that channel group, when the feature
Increased SDCCH Capacity is not available
• an average of 2 SDCCH/TRX in the cell, when the feature
Increased SDCCH Capacity is available, i.e. more than 2
SDCCH are possible in some channel groups
Note that by the function Adaptive Configuration of Logical
Channels, the number of required SDCCHs in a cell can be
automatically adapted depending on the demand for such
channels.

In Ericsson’s GSM system, the MS power can be controlled by
the parameter CCHPWR, which indicates the maximum

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
transmitter power that the MS is allowed to use when
performing an access to the system (GSM 03.22).
Whilst in idle mode, the MS continuously confirms that it has
chosen the most appropriate cell by calculating the quantity C1
from the received signal level rxlev:
C1 = (rxlev − ACCMIN) − max (CCHPWR − P, 0)
The MS camps on the cell providing the highest positive C1.
The condition states that an MS must measure signal strength
higher than ACCMIN from a cell to be able to access the system
via this cell.
In addition, if the MS maximum possible output power, P, is
lower than CCHPWR then the requirement on the signal
strength increases by the difference between P and CCHPWR.
This means that if the MS cannot reach the maximum output
power then the requirement on the signal strength in the
downlink is harder. In this case, the measured cell is probably
not designed for MSs of that class.
A low value of ACCMIN means that the coverage in idle mode
is improved at the expense of the risk of having an increased
number of call set-up failures.

In order to optimise cell reselection, the additional cell
reselection parameters CRO, TO, and PT are broadcast on the
BCCH of each cell. The cell reselection process employs a
quantity C2 for GSM phase 2 MSs, which depends on these
parameters (GSM 03.22). GSM phase 1 MSs use the quantity C1
for cell reselection instead, i.e. these mobiles do not experience
an offset.
The reselection quantity C2 is defined as:
C2 = C1 + CRO − TO * H(PT − T)
C2 = C1 − CRO
44(214)
for PT ≠ 31
for PT = 31

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
where
H(x) = 0 for x < 0
= 1 for x ≥ 0
T is the timer, started from zero at the point at which the cell
was placed by the MS on the list of strongest carriers. T is reset
to zero whenever the cell is no longer on the list of strongest
carriers. This will tend to prevent fast moving MSs from
selecting the cell (GSM 03.22).
The quantity C1 is given in the description of parameter
ACCMIN (page 36).
CRO applies an offset to the C2 reselection criterion for the cell.
TO applies a negative offset to C2 for the duration of PT after
the timer has started for the cell.
PT is the duration for which TO applies. The value 31 of the PT
parameter is reserved to change the sign of CRO and the value
of TO is ignored as indicated by the equation defining C2.
These parameters are used to ensure that the MS is camped on
the cell with which it has the probability of successful

Filter control – cell data
The measurement results are sent from the BTS to the BSC every SACCH
period (480 ms) starting when the MS is assigned an SDCCH. The measurement results are stored and filtered in the BSC. The signal strength and quality
measurements are filtered in order to smooth out measurement noise. In
addition, some fading components of a duration of about the same as the filter
response time, are filtered out.
When filtering measurements for a cell, always the filters that are assigned to
the cell are used. This means that serving cell and neighbouring cell
measurements can be evaluated by different filters, if different filters are
assigned to the different cells.
The locating filters are numbered from 1 to 9, and correspond to different filter
types:
1-5

General FIR filters.
Straight average filter.
Exponential filter.

Note: For a multislot configuration, only the main channel is evaluated. The

RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
If a measurement on a neighbouring BTS is missing in the
measurement report, that neighbour is not included in the
evaluation. When a new measurement report containing
information about that BTS is received, the missing values are
linearly interpolated. But the interpolation is only allowed if the
number of missing measurements is equal to or smaller than a
certain number that is determined by MISSNM. When the
number of missing measurements exceeds MISSNM all former
measurements from that BTS are discarded and the evaluation of
that BTS starts again when a new value arrives.
If an urgency condition occurs and there are no neighbouring
cells in the current measurement, the last received measurement
containing neighbours is used. If the number of missing
measurements exceeds the parameter MISSNM the old
measurements are considered invalid.
If a measurement from serving cell is missing, locating is
suspended until the serving cell measurements start again.

(Ericsson 1) or HIHYST or LOHYST (Ericsson 3) from the
average cell border, i.e. without hysteresis.
The value ON activates the penalty handling that consists of
sending a handover cause value to the target BSC.
The cause value is interpreted by the target BSC as “urgency
handover”. Both TA urgency as well as bad quality urgency can
be recognised. The target BSC carries out the punishment of the
cell in the old BSC that was abandoned. However, it uses the
penalty parameter value and penalty time of the new cell.
Note: EXTPEN should be set to OFF if the external
neighbouring cell belongs to a BSC from another vendor.

on the TCH, i.e. the locating function prepares a ranking list and
sends it to the handover function.

Handovers on SDCCH are allowed. This applies to both
handovers from and to the cell.

HIGH
The cell is a cell where minor changes of radio
transmission quality can be expected.
LOW
The cell is a cell where radio transmission quality
can be expected to deteriorate rapidly.
The load of the RPD can be automatically regulated by reducing
the rate of locating calculations for the MSs in the cells that are
least likely to perform a handover or to be subject to
disconnection.
In the case of regulation the calculations are performed for every
second measurement result arrival (approximately once per
second). All arrived measurement results are taken into account
in the time evaluation of measurements.
The parameter CELLQ is used to define whether a cell is
suitable for regulation or not. If CELLQ takes the value HIGH
then the regulation can be performed, i.e. it is assumed that there
is no risk for an increasing number of dropped calls if the rate of
locating calculations is reduced. If CELLQ takes the value
LOW then the regulation is not allowed.

Number of measurement periods before the full set of measurements are used.
The measurement results sent to the BSC every SACCH period
(480 ms) include a full set of measurements and a subset of
measurements. The full set of measurements is performed on
each TDMA frame in a basic physical channel. The subset of
measurements is performed on those TDMA frames in the basic
physical where transmission is guaranteed, see GSM 05.08.
The power control algorithm uses the subset if either DTX is
used on a TCH or during a time period after the call has just
been established on a TCH. This time period is specified by the
parameter DTXFUL. In all other cases the power control
algorithm uses the full set.

Dynamic BTS power control
The BTS power level can be dynamically controlled during a connection. The
power control strategy is towards a desired signal strength value received in
the MS.
The BSC calculates the new BTS power level by using the data measured by
the MS, i.e. the signal strength and the quality on the downlink TCH carriers
and the parameters described below. A compensation is performed in the case
of frequency hopping, which takes into consideration that bursts received and
measured by the MS may have been transmitted at different power levels. The
power level on channels at the BCCH frequency is not controlled.
The BTS can change its power level in steps of 2 dB, while the maximum
configurable change is 30 dB.

Command:

O&M:
Changing of this parameter might cause all ongoing calls in the
channel group to be dropped.
Comments:
Mobile Allocation Index Offset.
MAIO is a parameter that will allow the operator to specify a
list of up to 32 MAIO values, in the order in which they are to
be allocated to a channel group. This parameter can also be set
to DEFAULT, which removes the manual MAIO list in favour
for the default MAIO list.
The number of MAIO values in the list stretches from 0 up to
one less than the number of frequencies in the HFS. E.g. If there
are 9 frequencies in the HFS, the MAIO list will contain the
values 0-8.
The order of the MAIO values in the default list is arranged in a
"first even then odd MAIO values" manner. This means that the
beginning of the list will consist of all even MAIO values in
ascending order. After these even values all the odd values are
arranged in ascending order, e.g. for a hopping group with 9
frequencies the default list will be 0, 2, 4, 6, 8, 1, 3, 5 and 7.
The actual MAIO values to be used for a channel group depend
on the number of TRXs in the channel group. If e.g. three TRXs
are used for a CHGR, only the first three MAIO values in the
MAIO list will be used. With 9 frequencies in the hopping group
and three TRX, the used default MAIO values would be 0, 2 and
4. The remaining values will not be used unless additional TRXs
are added.

Baseband hopping.
Synthesiser hopping.
Frequency hopping can be achieved by two methods, baseband
or synthesiser hopping. The parameter FHOP indicates the
frequency hopping mode in the TG. When the TG is connected
to a filter combiner only baseband hopping can be used.
When baseband hopping is performed each TX is transmitting
on a fixed frequency, i.e. frequency hopping for a basic physical
channel (BPC) is obtained by switching TXs between each
TDMA frame.
For synthesiser hopping the TX switches frequencies for every
TDMA frame sent. In other words, each BPC is carried by one
single TX, except when a BCCH burst is transmitted. The
BCCH burst is in that case carried by the TX that transmits the
BCCH frequency.

Overlaid/underlaid subcells / Subcell Load Distribution
The serving area of an overlaid subcell is defined by four parameters. There
are three ways of restricting the size of an overlaid subcell; by restricting the
pathloss, distance to cell border and by limiting the cell radius.
By the use of subcell load distribution, the system attempts to keep as much
traffic in the underlaid cells as possible.
Note: Subcell Load Distribution evaluations are not performed at all for
channels in multislot configurations.

When a fast moving MS connected to a higher layer (lower
priority) cell passes through a lower layer (higher priority) cell's
coverage area, it might be undesirable that the MS performs a
handover to the lower layer cell. Therefore a penalty,
PSSTEMP, can be temporarily assigned to the lower layer cell
while a timer is running. The timer starts when the lower layer
cell is first reported as a neighbour and runs for a period
specified by PTIMTEMP.

areas, maritime environments etc., large cells could be valuable.
In order to configure cells with both normal and extended range
channels, a subcell structure shall be used. The normal range
channels will then be placed in the overlaid cell, while the
extended range channels will be in the underlaid cell.
Note 1:
Extended range is only supported by the RBS 200 using SPPboards. RBS 200 can only support traffic up to a distance of 72

90/1553-HSC 103 12/4 Uen Rev PE1 2004-05-26
RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
The number is the absolute RF channel number for the BCCH
for cells to be measured on by a mobile station in the cell.
MBCCHNO is the BCCH allocation, i.e. it indicates to the MS
the frequencies that must be monitored and measured in idle,
active or both modes. This number is sent to MSs in the system
information messages, on the BCCH channel in idle mode, and
on the SACCH in active mode.
Up to 32 BCCH carriers can be defined by specifying their
ARFCN.
The measurement reports from the MS are sent to the BSC on
the SACCH, indicating the signal strength and quality of the
serving link and the signal strength, frequency, and BSIC from
the six BTSs with strongest signal strength. Only measurements
from neighbouring cells that fulfil the requirement that their
BCCH has a frequency as indicated by MBCCHNO and an
NCC as indicated by NCCPERM are valid. To be allowed to
perform a handover to any of the measured cells it is also
necessary that the measured cell is defined as a neighbour to the
serving cell. Up to 64 different cells can be defined as
neighbours.

Enhanced Multi-Level Precedence and Pre-emption
Service (eMLPP)
The enhanced Multi-Level Precedence and Pre-emption (eMLPP) feature
enables the operator to give high priority users good access to the network.
This is achieved by pre-emption of one low-priority connection either by
handover or disconnection.
The BSS procedure uses two pre-emption indicators, PCI and PVI, that are
provided by the MSC. If a connection has no pre-emption indicator set it is not
influenced at all by pre-emption handling.

seconds to check if the criterion to remove one SDCCH is
fulfilled. A ‘leaky bucket’ counter algorithm determines this

During Urgency conditions for bad quality handovers (pages 67 and 68),
Dynamic MS Power Control (page 93), Dynamic BTS Power Control (page
98) and Intra Cell Handover (page 108), different values for some parameters
have to be considered for AMR FR connections. For this purpose, AMR FR
specific parameters BQOFFSETAFR, QLIMDLAFR, QLIMULAFR,
SSDESULAFR, QDESULAFR, SSDESDLAFR, QDESDLAFR,
SSOFFSETULAFR, QOFFSETULAFR, SSOFFSETDLAFR and

90/1553-HSC 103 12/4 Uen Rev PE1 2004-05-26
RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR ERICSSON’S GSM SYSTEM
In logical model G01 (RBS 200 series), a software function
called TGC is loaded into the transceiver controllers (TRXC) in
the TG. TGC is loaded into each one of the TRXCs, although it
is only activated in one at a time. The TGC handles common
control functions within the TG.
CTEI is used to address the TGC within a TG. CTEI must be
set to the same value for all TRXCs in the TG. The
recommended value is CTEI = 58. CTEI and TEI must not be
identical within the TG.
When LAPD concentration is used, each TRX that is connected
to the same LAPD concentrator should be addressed using
different CTEI values. The CTEI value should start with 58 and
be increased by one for each TRX within one site.
Note that CTEI must also be defined in the BTS.
CTEI is only be specified for a TG in the logical model G01
(RBS 200 series). In the logical model G12 (RBS 2000 series)
there is no TGC.

Command:
All commands where the TX has to be specified as a managed
object instance
O&M:
–
Comments:
The transmitter ID.
TXID is used to identify a certain TX within the TG in the
logical model G01 (RBS 200 series).
In the logical model G01 a TX does not belong to a certain
TRXC and has to be addressed separately. The value of TXID
must be the same as the HW position (0 to 15) of the TRXC to
which it is related.
TXID is not specified for the logical model G12 (RBS 2000
series) as there is only one TX for each TRXC in G12.
MPWR

Default:
–
Command:
RXMOI, RXMOC, RXMOP
O&M:
The parameter is only allowed to be changed when the
transmitter is out of service.
Comments:
Maximum Transmitter Power.
It is necessary to specify the capability of the transmitters
available in the TG. This is done in order to prevent power
orders, which the transmitters cannot handle.
MPWR is the maximum transmitter power of the TX at the
power amplifier (PA) output. MPWR must be specified for each
transmitter in the TG.
RXD
Type:
Identifier
Range:
A, B, AB
Unit:

Command:
RXMOI, RXMOC, RXMOP
O&M:
The parameter is only allowed to be changed when the receiver
is out of service.
Comments:
Receiver Diversity.
Combination of receiver antennae to be used.
A
B
AB
Antenna A used only.
Antenna B used only.
Receiver diversity employed using antenna A and B.
Even when the antenna arrangement is such that it can provide
diversity it is also necessary that the signal processing in the
transceiver unit can process and take advantage of the two
signals. This diversity feature at the transceiver must therefore
be specified for each TRX.
RXD indicates the use of receiver diversity in a given TRX.
