Bell Labs Innovation in Performance Monitoring
Industry Standard (Vs) Bell Labs’ CELNET Xplorer
• Mobile and network probes may be needed
• Aggregates all users • Hourly Averaged• Performance assessment• Minimal or no Inter-
technology information
• Per-user / Per-dataflow Monitoring• Event triggered on demand analysis• Correlated Analysis
• Terminal Type• Services Type• Performance metrics

Celnet XP is connected to the customer external switch.
An unused port should be located and a mirroring operation should be done to mirror the VLAN of the appropriate RAN, onto the selected destination port.
If the switch supports multiple RNCs then to monitor all these RNCs, as many mirror operations have to be enabled and as many Celnet Data capture modules should be connected.

Cell Measurements
Session Setup and User Initiated Calls
High Session Setup which exceeds User Initiated Callswhich is atypical for this sector
User Initiated FCA’s
High No RL Acq Rate over a short period
