Some general points

• A One Hour Recording will give agood understanding of the site QoS

• This will produce between 50 & 1000Mbytes of Binary data

» All depending on technology traffic loadand covered links.

ALWAYS ENSURE……


• That all relevant signaling links areavailable!

» Anything else will result in anunusable result.

• How to tell?» The File processing report will show whether the file has been processed

correctly or not. A small test recording will tell that quickly.

Product focus.

• Providing network operators with the tools to determine

» Where am I losing revenue?

» Why am I losing revenue?

» How can costumer perceived quality be improved in order to gainrevenue?

• A post-processing tool that gives operators a user-centric view ofthe network


» Is the throughput of this service satisfactory?» Where were calls dropped?

» Is the datacom service too bursty?

• But still with an eye on the network

» Was the correct parameter sent between the BTS and the BSC?

» Are the average cell change times acceptable?

Typical issues investigated using




34

Typical issues investigated using CompassWireless: Congestion.

• Quick identification of the affected cells


•

• Detailed information

on resource usage



35

Network information (OMC).

• Congestion information can of course be collected fromthe network itself

BUT

• It will require that information from various sources aremerged and there will be no details


Compass:

• Collects all information in one program

• Provides details all the way down to decoding

Be aware: Congestion on TCH and SDCCH is more efficiently monitored by OMC-statistics,but analyzing this and congestion on other control channels is a task for Compass



36

Typical issues investigated using CompassWireless: Lost roamers and dropped calls.

• Quick identification of cells where roamersare likely to be lost

• Specific information on where in


the cell the problem lies

• Visual identification ofcoverage issues



37


• Roaming information can of course be collected from thenetwork itself

BUT

• It will require that information from various sources aremerged and there will be no details


Compass:• Collects all information in one program• Provides detailed information on:

» Where roamers camp on the network

» From where roamers is acquired» Where roamers could be lost



38

Typical issues investigated using CompassWireless: Throughput issues.

• Does throughput matchthe mobile class?

• What length of time doesthe average cell change


• Does the userexperience unacceptablyslow round

trip times?

O



39


• Throughput information can of course be collected fromthe network it self

BUT

• No detailed information is available only max, min and avgthroughput information is available


Compass:• Collects the same information, but with more details so

the Compass user can get the real customer feeling ofnetwork access quality:

» Throughput per Cell» Throughput per User» Throughput per Session

40

C



40

Typical issues investigated using CompassWireless: Incorrect parameter in message.

• Visual of up and downlinkquality and strength during

the call


• Correlation of all messages relatedto the call

• Drill down into the individualmessage

41

Network information (OMC, Drive Test).

• Radio information can of course be collected from thenetwork itself, mostly by use of drive test

BUT

• Drive tests onl rovide downlink information


• Drive tests only represent a few MS

Compass:

• Collects all information in one program

• Provides information on both Downlink and Uplink

• Represent all users in the recorded area

T i l bj ti



43

Typical objections.

• I already use drive test. I don’t need your solution» Compass is complementary to drive test and uses your

subscribers as drive testers. Compared to the resources used in

drive test, Compass is a much more cost-effective solution and itprovide you with both up- and downlink.

• I already use OMC statistics» Yes, the OMC can maybe point you in the direction of the


problem, but there is no useful information here that can help you

resolve the real root of the problem.

• My network’s perfect» Quality of mobile networks is always a tradeoff between

acceptable quality level and resources. Compass can tip this

balance and put you ahead of your competitors.» Maybe we can take a look and help identify some areas that could

be improved.

44

T i l bj ti t’d



Typical objections cont’d.

• It’s time-consuming to collect data

» Why not use a distributed approach with fixed probes?

» How much time do you spend today to resolveproblems in the network?

• We’ve developed our own tools in-house


» What’s the annual cost of your R&D?» How does this compare to the cost of Compass

» Compass is developed based on +10 years of know-how and feedback and experience from a largenumber of operators and vendors throughout the world.I’m sure you can use this to your advantage

45

Typical objections cont’d



Typical objections cont’d.

• I already have a protocol analyzer. Why do Ineed another tool?» As a post-processing tool, Compass correlates all

messages to individual users and over multipleinterfaces making it easier and quicker to pinpointproblems


transactions where something has gone wrong, withoutyou having to know what that something is

» Compass provides visual views showing exactly how asubscriber has experienced a service throughout the

service – handovers/cell changes/dropped call, not justindividual message dumps that have to be interpreted
