Upgrade Prerequisites




The Core Network can be upgraded either before or after WCDMA RAN
for all upgrade paths.
New hardware must be installed in affected nodes, and old hardware
removed.
Note: All necessary field change orders must have been performed prior
to upgrade.
The old WCDMA RAN P6.x LKF (Licence Key File) will not work in a
WCDMA RAN P7.0 node. The WCDMA RAN P7.0 product must be
correctly ordered to receive the P7.0 LKFs. Those P7.0 LKFs must be
pre-installed in the from-state before upgrading. Note that before
installing the licences it is important that the system clock for the
node is set correctly. Failure to install the licences shall result in lost
functionality or capacity after the upgrade. An alarm is issued when the
LKF is missing. Concerning license controlled features which were active
in the from-state, the AUE will handle the activation. For new features, the
operator has to activate them, when they are to be used.
Capacity licenses in both RBS and RNC must be ordered and installed
with enough capacity in order to retain existing capacity.

System Improvements in WCDMA RAN P7 Release


This is an optional feature in the in WCDMA RAN P7.0.
This feature contains all enhancements and improvements
that are not covered by other features for the WCDMA
RAN 7 release and are of commercial value. Following
enhancements and improvements are added:
- Compliance with 3GPP Release 7, for functions that are
implemented
- Reduced downtime at RNC restart
- ISL Load Control
- Improved In-Service Performance
- Node-level load balancing in the RNC
System Improvements Network Performance Impact




Improvements to streamline the RNC-internal procedures during
restart, resulting in shorter restart times have been introduced.
In RNC a new load control for the Inter-Subrack Links has been
introduced to provide a reliable protection from ISL overload. The
mechanism regularly measures the load on each ISL. When the
load is approaching the link capacity, the Packet Data Router will
reduce the user plane traffic to avoid overload. This ensures robust
behavior also in very high traffic situations and allows for a
Maximum Iub throughput of up to 1200 Mbps.
In-Service Performance for the RNC is improved by introduction of
memory pool protection of USAAL. This is done by flow control of
NBAP-C/D messages sent from RBS to RNC. This features ensures
that the USAAL server will not fill up its pool memory and cause a
module restart in RNC. Traffic overload protection involves a flow
control mechanism allowing USAAL to check if NBAP-D and NBAP-C
are ready to receive more messages. The USAAL, server in
communication with NBAP, will add and receive flow control
information (sequence numbers) in the signal flow, such that it can
protect against buffer overruns and prevent restart during heavy
traffic.
The Module MP processor load balancing mechanism is introduced
in P7 which will balance the load within the complete RNC,
essentially removing the need for frequent remoduling (moving
RBSs between subracks). This will increase the utilization of the
RNC HW.
System Improvements Operation Impact

The WCDMA RAN P7.0 CPI introduces a new concept, a
library collection. The change presents all the
documentation for all WCDMA RAN nodes in one view
providing the end user with better navigation between the
related CPI products for the WCDMA RAN release. It also
provides support for multi-library download and searching
multi-libraries and removes the need for having several
browsers open with various node libraries in parallel. The
change does not impact the end user, in that no actions
need to be taken. The enhancement is graphical and
presents a coherent view of all WCDMA RAN CPI.

Conversational RAB for Multimode AMR speech

This optional feature, Conversational RAB for Multimode AMR
Speech, is enhanced in WCDMA P7.0.
 This feature provides the possibility to increase the capacity for the
speech service by making it possible to use lower codec rates for
speech when there is a high load in the radio network. The feature
also allows for increasing the speech coverage by using the lower
speech codec rates.
 The feature provides a conversational Radio Access Bearer (RAB)
for multi mode AMR speech with the following rates:
- 12.2 kbps
- 7.95 kbps
- 5.9 kbps
- 4.75 kbps
 The operator can choose between two different realization
alternatives for this RAB, that is, either single rate or multi-rate .
Conversational RAB for Multimode AMR speech
 The 12.2 and 7.95 kbps rates use the downlink
spreading factor of 128, while the 5.9 and 4.75 kbps
rates a spreading factor of 256. The higher spreading
factor for the two lower codec rates also gives
improved code utilization.
 The core network assigns this multi-mode AMR RAB by
making a RAB assignment with these 4 rates. The
selection between the two alternatives (that is, single or
multi rate radio bearer) is controlled by the operator on
a cell level. The selection is done at RAB assignment
and the selected alternative will not change due to
mobility.
Conversational RAB for Multimode AMR speech
 WCDMA RAN P7.0 release, the following RAB
combinations will have the AMR multi rate radio bearer
12.2, 7.95, 5.9, 4.75) in the RB combinations:
- Speech + (1-3)x PS interactive on both rel 99 and HSDPA
- Speech + PS streaming on rel 99
- Speech + PS streaming on HSDPA except for the 32/HS and 128/HS
streaming cases and the combinations with multiple interactive bearers
Multimode AMR speech Network Performance Impact




In high load situations there will be an improved speech capacity
in the radio network by reducing the speech codec rate. The
feature enables the higher speech codec rates when the radio
network load allows for that.
Improved code utilization is introduced due to the higher spreading
factor for the two lower AMR rates (applicable for the single rate
radio bearer alternative).
Improved coverage is possible for the speech service with the
lower speech codec rates.
Introduces possibility for the UEs to adapt between the different
uplink codec rates due to uplink coverage (applicable for the multirate radio bearer alternative).
Multimode AMR speech Operation Impact


The feature is under license control.
The following parameter can be set on cell level by the operator,
amrNbSelector, to enable AMR NB MM. Single-rate is the default
configuration.
 New Erlang and traffic volume counters for AMR MM are introduced;
- pmSumAmrNbMmRabEstablish
- pmSamplesAmrNbMmRabEstablish
- pmSumBestAmrNbMmRabEstablish
- pmSamplesBestAmrNbMmRabEstablish
- pmUlTrafficVolumeAmrNbMm
- pmDlTrafficVolumeAmrNbMm
 Following GPEH Parameter is updated to include speech configuration:
- EVENT_PARAM_SOURCE_CONNECTION_PROPERTIES
- EVENT_PARAM_TARGET_CONNECTION_PROPERTIES
 For the multirate case existing parameters are used to configure at which
load in the radio network the different rates shall be selected as maximum
rate and thereby having the higher rates excluded from the selection.
Multimode AMR other requirements





This feature requires the feature Conversational RAB for AMR
Speech FAJ 121 146.
The value of this feature is increased if paired with the feature
Stand Alone SRB 3.4 kbps that adds possibility to use lower
signalling rates and extend the SRB coverage in a cell to match
the coverage area of speech calls when the low rate speech codec
is used.
When this feature is activated and the parameter amrNbSelector is
set to AMR NB MM and the feature Measurement Function Radio
Environment Statistics FAJ 121 514 (RES) is used, there is a
limitation in that RES will not support the recording of AMR NB MM
(there will be fewer samples for the RES service speech).
This feature requires support in the Core Network. Support for
AMR MM is required in the UE.
Iu UP version 1 must be used

Stand alone SRB 3.4 kbps
 The optional feature Stand Alone SRB 3.4 kbps is new
in WCDMA RAN P7.0.
 The possibility to have a stand alone SRB with the rate
3.4 kbps instead of the default SRB rate of 13.6 kbps is
introduced. SRB 3.4 kbps requires less resources than
SRB 13.6 kbps, which means the coverage and
capacity can be improved. In particular, if SRB 3.4 kbps
is combined with using a lower rate speech codec of
AMR NB or AMR WB, the coverage of the speech
service can be improved.
Stand alone SRB 3.4 kbps Network Performance Impact
 When the SRB 3.4 kbps is used this will increase the
SRB stand alone coverage and the number of
simultaneous users of the SRB in a cell (consumes
less resources/lower data speed). The increase in
coverage area can lead to an increase in Accessibility.
 Since the SRB 3.4 kbps has a lower signalling rate, the
call setup signalling will take longer (estimated 1-1.5s
increase) than when SRB 13.6 kbps is used. The
choice to use SRB 3.4 or SRB 13.6 kbps is operator
configurable on cell level. The increased time on SRB
could result in decreased retainability.
Stand alone SRB 3.4 kbps Opration Impact







The feature is under license control.
A cell parameter, standAloneSrbSelector, is used to select if SRB 3.4 or SRB 13.6
kbps will be used in the cell.
New PM counters are introduced;
New Retainability counters for SRB
- pmNoNormalReleaseSrbOnly34
- pmNoSystemReleaseSrbOnly34
- pmNoNormalReleaseSrbOnly136
- pmNoSystemReleaseSrbOnly136

- pmDlTrafficVolumeSrb34
- pmUlTrafficVolumeSrb34
- pmDlTrafficVolumeSrb136
- pmUlTrafficVolumeSrb136
This feature is not dependent on any other feature, but the value of this feature is
increased if paired with the feature Conversational RAB for AMR Speech that adds
possibility to use lower speech coding rates and extend the speech service
coverage in a cell to match the low rate SRB.

Statistical Observability

The optional feature Statistical Observability, is enhanced in
WCDMA RAN P7.0.
 Counters for new and enhanced optional features, for example 64
QAM and Cell Broadcast Service have been added.
 In RBS the possibility to view the blocked calls caused by shortage
of licensed resources have been added. It will also be possible to
observe the level of statistical utilization of the licensed resources
in an enhanced way. The licensed resources in RBS covered are
the following:
- Channel elements
- HS-DSCH users
- HS-PDSCH codes
- E-DCH users
 RBS capacity status can be monitored and resources managed
accordingly. Taking necessary action will ensure that subscribers
experience less access blocking and dropped calls.
Statistical Observability





The operator will be able to predict shortage of licensed capacity and
thereby prepare the system for higher subscriber capacity.
The experienced quality of the network will improve as fewer calls will
be blocked caused by shortage of RBS and RNC resources.
The enhanced observability will predict need for investment in more
licenses of channel elements, but also hardware if all available capacity
is already utilized.
Maintenance personnel will be informed when licensed resources are
scarce and can act accordingly to offset the shortfall.
The observability is supplied with the licenses it monitors. In addition
the following new RBS counters are introduced monitoring the RBS
capacity status:
- pmCapacityDlCe
- pmSamplesCapacityUlCe
- pmSumSqrCapacityHsPdschCodes

Cell Broadcast Service


The CBS feature enables broadcast of short text messages to
defined geographical areas known as Cell Broadcast Service
Areas (CBSAs). The messages are repeated over the air interface
at a frequency and for a duration agreed by the content provider.
CB messages are generated by the Cell Broadcast Center (CBC)
and sent to WCDMA RAN via the Iu-BC interface. The CBC is an
external node provided by the operator, that is, the functionality is
not integrated in the Ericsson Core Network.
Cell Broadcast Service



The Service Area Broadcast Protocol (SABP), is used to distribute
CB messages from CBC to a number of CBSAs in RNC. Each
CBSA contains only one UTRAN cell. Both IP and ATM transport is
supported in WCDMA RAN.
The CB messages received from CBC are stored in WCDMA RAN
and the Broadcast Multicast Control (BMC) protocol is used on the
Uu interface to schedule and broadcast corresponding BMC CBS
messages in the cell. Each BMC CBS message contains one CB
message. The BMC CBS messages are sent on the logical
channel CTCH using RLC unacknowledged mode. The CTCH is
multiplexed on a FACH transport channel carried by a Secondary
CCPCH.
CB messages are received by UEs in Idle mode and in state
URA_PCH. The UE will monitor the CTCH during time intervals
which do not conflict with the UE specific paging occasions on
PICH.
CBS Capabilities



A maximum of 20 CB messages, or a total payload of 2.5 kbyte,
can be stored per CBSA in the RNC. When this limit is reached
new CB messages addressed to the CBSA are discarded. If a CB
message is discarded the cell counter
pmNoDiscardedCbsMsgOrders is stepped.
The maximum number of CBSAs is 65535 within a PLMN and
2304 within an RNC.
The size of incoming SABP messages is limited to 18000 octets.
This should be large enough to cover a SABP WRITE-REPLACE
message containing 2304 CBSAs. If the size exceeds 18000
octets the message is not decoded and WCDMA RAN responds
by sending an SABP ERROR INDICATION to CBC.
Cell Broadcast Service Area





The CBS feature includes the area concept Cell Broadcast Service
Area (CBSA) which represents the smallest geographical area
where a CB message can be broadcast. The CBSA is only used
towards the CBC node and it contains one UTRAN cell.
The service area identity (SAI) for a CBSA is defined as:
PLMN id + Location Area Code (LAC) + CB Service Area Code
The CB Service Area Code is configured in the RNC and the value
is set by the cell parameter cellBroadcastSac. For PLMN id and
LAC the already configured values for the cell are used.
In order to avoid configuration mismatch OSS provides a
consistency check rule for verifying that the CBSAs are unique in
all cells in the network. Warnings will be issued in case on nonunique SAI as same SAI in different cells may cause broadcasting
of CB messages in the wrong area.
If the cellBroadcastSac parameter is set to “undefined” no CB
messages can be broadcast in the cell.
Start of CBS operation




In order to start CBS operation the following criteria must be fulfilled:
1. The CBS feature is activated and the license is loaded,
2. The Iu-BC link is configured,
3. The cells in which CB messages are to be broadcast are enabled and a CBSA is
defined for each cell,
As soon as criteria 1 and 3 are fulfilled, the CTCH configuration is included in
system information, SIB5, and the UE will start monitoring the CTCH occasions on
S-CCPCH in cells where a CBSA has been defined. However, no CB messages
can be broadcast in the cells as long as the Iu-BC link is not configured.
Once all criteria 1, 2 and 3 above are fulfilled, RNC informs CBC about the service
areas that are operable by sending a SABP RESTART message. The SABP
RESTART message contains a list of all defined CBSAs within the RNC.
If a cell with a defined CBSA becomes disabled the broadcast is stopped in that cell
and all stored CB messages are cleared. As soon as the cell is up again a restart
indication is triggered for the cell. To avoid that SABP RESTART messages are
sent too often over the Iu-BC interface a periodic timer of 30 seconds is
implemented in the RNC to monitor the restart indications. Whenever the timer
expires RNC will send a SABP RESTART message to CBC containing a list all
CBSAs that have triggered a restart indication during the last 30 seconds. If there
were no restart indications when the timer expires, no SABP RESTART message is
sent for that period.
Reception of a SABP WRITE-REPLACE message
Scheduling of BMC messages over the Uu interface




The logical channel CTCH is multiplexed on FACH1, carried by the
existing S-CCPCH used for 32 kbps Interactive PS RB and SRBs. The
CTCH is scheduled on S-CCPCH during predefined CTCH occasions.
The CTCH occasions are fixed on the SFN cycle 0...4095 and thus
repeated cyclically.
CTCH occasions are defined as the radio frames in which the following
equation is true:
SFN = K + m*N, m = 0, 1, 2, ... M ( Reference [5])
K is the offset to the first CTCH occasion on the SFN cycle. The value is
hard coded to 0.
N is the period of CTCH occasions on S-CCPCH. The value is set by the
parameter ctchOccasionPeriod.
M is chosen so that K + M*N 4095 (Max SFN)
Note that the TTI for FACH1 is 10 ms, that is, each CTCH occasion
corresponds to one TTI on FACH1
Note: Changing the attribute ctchOccasionPeriod will affect any ongoing
traffic in the cell. Whenever its value is set, the cell is disabled
automatically and then re-enabled.
Iu-BC interface

the Iu-BC interface will be connected to the same O&M IP network as Mur implies the
following:
- QoS must be considered as the Iu-BC traffic will compete for bandwidth with the O&M
traffic
- Iu-BC interface and traffic will experience the same level of network security as O&M
traffic and as provided by the O&M IP network
- The CBC node must be connected to the O&M IP network
- The O&M IP network must allow the TCP port for SABP 3452 and will compete for
bandwidth with the O&M traffic
 From RNC to CBC node the Iu-BC traffic will get the same QoS characteristics as
O&M traffic.
 The dimensioning of the O&M IP network should take into account Iu-BC traffic. The
Iu-BC traffic volume is expected to be low and the impact on the dimensioning should
be small.
C Iu-BC = Msglength * numMsgs/second
Msglength is the length of the SABP message. Note that the maximum length of a
SABP message that can be processed in WCDMA RAN is limited to 18000 octets.
numMsgs/second is the number of SABP messages sent over the Iu-BC interface per
second.
 To improve security it is recommended to turn on the Filter for IP source address
validation in the RNC by setting parameter sourceIpAddressValidation to TRUE. This
filter will avoid the establishment of connections from other IP source addresses than
the configured IP address for the CBC.It is possible to turn this filter off if there is a
need to establish connections from more than one IP address.

RBS Auto Provisioning



The feature simplifies the integration of RBS into the network and
shortens the site integration time. The feature makes it possible for
a site technician to easily and rapidly integrate an RBS into the
network, without any support from the OMC personnel.
Note: For ATM-RBSs the semi automated procedure has to be
used (as ATM-RBSs initially cannot access the DHCP server).
The amount of information needed at the site visit is minimized, as
the preparations are made in advance. During the integration the
RBS configuration is automatically downloaded from network
repositories (FTP (SMRS) and DHCP servers respectively). IP
connectivity to the site is required for taking advantage of the AutoIntegration of RBS feature. This means IP connectivity over
Ethernet or over ATM for IP- or ATM RBSs respectively.
RBS Auto Provisioning



In order to utilize this feature to its full extent the following servers are in operation
in the O&M infrastructure (COMInf) are required:
- Bi-SMRS server (used as a repository for the RBS configuration files)
- DHCP server (based on IP Works)
The Bi-SMRS server requires the hardware servers NESS and NEDSS. However,
the semi-automated process can always be used independently if the Bi-SMRS or
the DHCP servers.
The site technician launches the Auto-Integration of RBS application GUI and
enters the needed information (RBS logical name and so on). The Auto-Integration
process then starts and it consists of a number of steps, all performed
automatically without any operator intervention.
To be able to utilize the Auto-Integration of RBS feature preparations have to be
made in advance. The amount of preparation data differs depending on the type
Auto-Integration procedure (semi automated or not). Not all preparations are
needed in semi automated procedure as the RBS configuration files are stored in
the LCT and not in the network repositories.
(1) When semi automated procedure is used the Basic IP data is included in the
Site Basic configuration file (same as for manual integration of RBS).
(2) When semi automated procedure is used the Site Basic and External HW
configuration files need to be stored on the site technician LCT before travelling to
the site (same as for manual integration of RBS).

HSDPA Users per Cell






This optional feature HSDPA Users per Cell is enhanced in WCDMA RAN P7.0. with support for
upto 64 HSDPA users per cell in RBS. The feature also introduces the possibility for the
operator to configure A-DCH processing capacity. Note that the total number of users in 3 cells
cannot exceed 96.
The feature increases the peak level of subscribers that can be handled in a cell from 32 to 64.
HW capacity (number of HSDPA processing resources and configured A-DCH capacity) should
be matched to the licensed or configured level or users. In RNC, there are cell admission
control parameters that need to be tuned to the correct value, dependent on what license level
there is in the RBS, or how the parameters maxNumHsdpaUsers and
maxNumADchReservation are set. Amount of A-DCH to allow in RBS shall also be tuned via
parameter numAdchReservation
The existing license FAJ 121 1011 is extended to have the following 2 more license levels
allowing up to 64 users:
- 33..48
- 49..64
The new parameter numAdchCeReservation to allow the operator to control the resources for
A-DCH.
Following new counters are introduced,
- pmUsedADch : A-DCH resource utilization
- pmAllocRejADch : A-DCH blocking
- pmAllocRejHwHsDschUsers : number of users blocking
Number of carriers in RUW/RRUW based RBS
 This license Number of Carriers in RRU/RRUW based
RBS is new in WCDMA RAN P7.0. Support for up to 12
carriers per RBS is introduced.
 This license applies to RBS equipped with RUW or
RRUW radio units. In case of an RBS configuration
with a mix of, for example RRUW and RRU22 the
license will only apply to the RRUW subset of the
configuration.
 The licensed level must be equal to, or exceed, the
number of carriers in the RBS.

This license Number of 60W power amplifiers in RRU/RRUW based RBS
is new in WCDMA RAN P7.0. With support for up to 12 power amplifiers
per RBS.
This license applies to RBS equipped with RUW or RRUW radio units. In
case of an RBS configuration with a mix of, for example RRUW and
RRU22 the license will only apply to the RRUW subset of the
configuration.
The licensed level must be equal to, or exceed, the number of power
amplifiers configured to 60W nominal output power in the RBS.
The parameter maxTotalOutputPower is introduced to set the nominal
output power of each RRU/RRUW. Each time a power amplifier is
configured with a certain nominal output power the setting is compared
with the licensed level. Configuring 60W requires that licensed 60W
capacity is left. Configuring 40W requires that either licensed 40W
capacity or licensed 60W capacity is left, although the 40W capacity will
be used first in this case. Configuring 20W requires no license.
This license is closely related to the licenses
NumberOf40WPowerAmplifiers FAJ 121 1347, and Number of Carriers in
RUW and RRUW based RBS, FAJ 121 1344.

IF/IRAT Mobility on HSPA






This feature introduces support for Inter-frequency and Inter-RAT mobility for RAB
combinations mapped on DCH/HS and EUL/HS, that is:
- IRAT and IF handover evaluation using compressed mode measurements
- IRAT handover (IRATHO), IRAT Cell Change (IRATCC) and Inter-frequency
handover (IFHO) execution.
The existing algorithm to start preferred type of HO evaluation and compressed
mode measurements shall be applied for RAB combinations on HSPA channels.
The parameters that control if GSM and/or IF handover is allowed shall be updated
for the affected UeRc states.
For IFHO the target cell must have the same capabilities as used in the source
configuration. A connection on EUL/HS can for example only be handed over to a
cell that is capable of both EUL and HS. If the capabilities of the target cell do not
match the current configuration in the source cell a down switch to DCH/HS or
DCH/DCH is performed before the IFHO is executed.
The same signaling sequences as used today for IRATCC and IRATHO can be
applied for HSPA connections. However, the use-case for IFHO needs to be
updated in order to support the establishment of a new serving HS-DSCH/E-DCH
radio link on the target frequency and at the same time perform a serving cell
change to this radio link.
The feature is optional and controlled by a license key, FAJ 121 1106 – CXC 403
0022.
This feature will only consider compressed mode for 10 ms TTI EUL.

HSDPA and EUL Mobility



For HSDPA and EUL Mobility a number of use-cases are linked together
using the same trigger. A few examples of 2- or 3 step procedures are
given below:
- Event 1b or 1c may trigger a serving cell change followed by a RL
Removal (if the HS/EUL serving cell is to be removed).
- Event 1c may trigger a serving cell change followed by a RL
Replacement (if the HS/EUL serving cell is going to be replaced by a new
EUL capable cell)
- Event 1c may trigger a serving cell change followed by a reconfiguration
from EUL/HS to DCH/HS followed by a RL Replacement (if the HS/EUL
serving cell is going to be replaced by a new non EUL capable cell and
event 1d-RNC is triggered)
If a 2b or 3a Measurement report is received during this time it shall not
be processed until all linked procedures using the same 1b or 1c trigger
have been completed, i.e. the use-cases listed above shall not be
interrupted by an IFHO or an IRAT HO/IRAT CC.
Once the linked procedures have been completed the event buffers shall
be searched using the same priority order as specified in the design base
for RAB combinations on DCH/DCH,
Inter-frequency handover execution
