Secure^QOS

As soon as a mobile service is launched, operator’s obligation is to ensure that network offers the level of service expected by mobile subscribers. A current process starts with supervision team reporting problem identified through alarms or with subscriber complaining about recent bad experience of mobile services. Answer must be given fast in a context of stabilized Average Revenue per User (ARPU) demanding for efficient tools minimizing OPEX.

Technical teams must also encompass always larger technological scope from 2G to 4G, from radio interface to data user plane. This calls for an end-to-end solution providing various views in a same screen.

• Monitor your quality of service in real time 24/7
• Handle customers complaints efficiently
• Immediately identify root causes of reported alarms or network dysfunction
• Reduce customer turnover
• Save time and reduce OPEX in troubleshooting

Customer care activity often needs to be able to replay all transactions performed by a specific user. It is also useful to know what transaction context lead to a studied problem. Subscriber activity displays the list of all transactions, whatever the domain is, related to a selected IMSI or MSISDN.

For any transaction recorded, Secure^QOS gives access to complete message flow in a graphical way displaying all useful information: main protocol information in tooltips, message time on a graphical time scale, used protocols using different colors, etc.

In a second step, it is then possible to extract corresponding raw binary traffic to small files in various formats that can be sent to experts for analysis. All messages related to selected transaction are displayed through all monitored interfaces.

Another mode allows extracting all traffic from every interface during a period of time. All recorded protocol messages can then be visualized in common message viewers from the market.

Secure^QOS provides a complete set of KPIs allowing a clear picture of how network behaves. These KPIs include transaction counts, failure counts, failure percentage, cause distribution for various transaction like voice calls, handovers, Normal Location Update, PDP Context Activation, etc.

By simple click, users get detailed information like causes, involved equipment or subscribers. They can dig down to subscriber activity and binary message decoding.

A complete reporting capability is also included.

To directly draw attention on the right KPI to look after, Secure^QOS provides an alarm module that raise alarms on user pre-defined KPIs crossing threshold or on specific events.

Results are displayed in various format including classical tables and curves showing trends, out of range values or benchmarks.

Depending on features, reports can be then linked together using drill down capability in order to get all required information to put light on selected point of interest.
