RAN Optimization
OptiMon Summary
Goal of OptiMon................ Improving the performance,
– of the Radio Network (QoS)
– and the mobile services (QoE)
… and make sure that it remains optimized
While................................. Cutting the costs of the Network Engineering
– by reducing Drive Test
– by improving the problem assessment process
Who should use OptiMon... Optimization departments + Professional Services
– Operators’ optimization teams
– Manufacturers’ professional services
Organizations involved....... Optimization dept.,
– doing the RAN Optimization in two steps, known as Level 1 and Level 2
Operations dept., – doing the RAN monitoring and troubleshooting.
Key values of OptiMon…... based on the analysis of the CP and UP data from all the subscribers
– Independent from Network Equipment vendors – not all NE issues are triggering OMC alarms (sleeping cells…)
– not all vendors communicate the exact definition of their KPIs
– Streamlined suite of tools (all compatible) – Can share information between departments
– Aggregates data from different sources (DT, CP/UP data, NM system)
– Scalable architecture: – can add more processing units when the traffic increases
9

RAN Optimization
Optimization Challenges [1/2]
The need for UTRAN parameters optimization (Level2) is much more
important compared to the 2G
– Due to the complexity of the UTRAN technology
– and 3G pushing the resource management to the access network
More time must be spent on L2 optimization while the other tasks are
not disappearing.
As a consequence, operation organizations are overloaded and don’t
address proactively L2, the most challenging task.

RAN Optimization
Optimization Challenges [2/2]
The number of trouble tickets resulting from a lack of L2 optimization
is significantly growing, representing at least 50% of the 3G+
customer complaints

3G moderate traffic 50 50 30 130
3G high traffic 50 50 50 150

Without proactively addressing L2 issues, operators take the risk to…
– Have increasing customer satisfaction issues
– Lose market share to the competition
– Waste radio resources
– Over invest in radio network due to poor efficiency
16
RAN Optimization
The bandwidth race is not over
With HSPA evolving to Ultra High Speed in 2008, the L2 optimization
will become vital

Analysis for Reference Cell:
Cell spacing: 300…400m
Call setup distance: approx. 11% of call setups occur from >/= 600m (and 4% >/= 1000m)
Distance between sites is not a good indicator
for the actual cell coverage area
QoE problems occur most likely in coverage
spots far away from sites
36
Use Case:
Geo-localization of network problems
Recommended actions:
1. Consider tilting down antenna of cell A
– Check for canyon effect due to long straight
road with buildings
2. Verify that cell B and C are in the neighbor
list of cell A

C
“In this case, a significant quality
improvement was achieved without
any drive test.“

46
Automatic Alarming
OptiMon will generate
automatic alarms that are
submitted to configurable
users by email or SMS.
Users will have the
possibility to define
thresholds:
– absolute thresholds, e.g.
call drop rate exceeds 2%
– relative thresholds, e.g. a
change in call drop rate of
0.5% compared to
previous value
Thus, users do not have to
observe OptiMon
continuously, but will be
notified if any configured
threshold has been
exceeded.

Strategy: – entry-point into optimization
– optimizers: are often not used protocol testing, while other peer
departments have NSA already
– Inexpensive up-sell opportunity for NSA customers
– get foot into the door
– don’t need TrendNavigate
– Positioning compared to Actix & Co.:
– we are not replacing DT post-processing platforms
– only indirectly competing: price & features
Key Values: – access to the entire chain: Uu - Iub - Iur - Iu
– DT is blind on anything else beside Uu!!!
– See all calls in RNC + KPIs
– ---> paving the road for TrendNavigate

DT-Synergy
DT-Synergy supports four DT vendors – R&S Romes
– Agilent Nitro
– E/// TEMS Investigation
– Anite Nemo
– Each vendor has been field-tested (VFD2, SFR, NSN, MKA, …)
How to get support for additional DT tools? – Opportunity – bring us friendly customers
– Approx. 15 different drive test systems are used in the market
– TEMS, Romes, Nitro and Nemo have a market share together of
>66%

Use Case Example: Signaling on Uu, Iub and IuCS RNC Does Not Respond Call Drop
In this period SC 405
is fading out but the red
Color is indicating that
it is still the serving cell
In this period SC 95 is
red because it
is serving the call but
there was no SHO before
55
From this picture you
can see that mobile
behaves correctly. It
sends event 1a with
SC96 towards the
RNC. But RNC does
not react. Either the
neighbor is not
defined or the RNC
is in overload.
RNC is the root
cause for missing
handover
There are red dots that identify
Measurement reports from the
mobile.
But there is no blue icon that
identifies RNC actions – e.g.
Active set update

Femto Cell: Network Topology without Iu-h support
NSA can monitor simultaneously the Iub, IuCS, and IuPS interfaces at the RNC and HNB GW
– Both ATM and IP transport are supported
– 3GPP R6 is fully supported, R7 will be available in Q1’2009
– LTE is also supported
All the interfaces in the Mobile Core are also supported

Femto Access Plan: implement Iu-h
DSL Modem / Router DSLAM
IuCS

With the Iu-h protocol stacks implemented, NSA will be able to trace
the calls end-to-end:
– until IPsec is implemented, the vendor must configure the HNB/HNB-GW
without IPsec encapsulation
