## Abstract

An Aggregate Location Dynometer (ALD) in a physical wireless network alerts to a problematic crowd risk using location based services (LBS). An Aggregate Location Dynometer (ALD) comprises a Network Monitor, a Crowd Risk Determinant and an Alert Module. The Network Monitor monitors wireless traffic for a potential viral event, associated with a formation of a plurality of wireless devices. The Crowd Risk Determinant requests location information associated with a plurality of wireless devices in a given area regarding a respective viral event. The Crowd Risk Determinant determines if the viral event also indicates a crowd safety risk, based on the shape and movement of observed wireless devices. The Alert Module triggers an alert of an impending crowd problem when crowd risk is above a given threshold. Historical databases are empirically determined and maintained in the Aggregate Location Dynometer (ALD) for use in viral event and crowd risk assessment.

## Claims

### Claim 1

An aggregate location dynometer in a physical wireless network server, said aggregate location dynometer comprising:
a network monitor to monitor a wireless network for an indication of a possible viral event;
a crowd risk determinant to assess location information pertaining to a possible viral event triggered by said network monitor; and
an alert module to alert in an event of a public safety risk determined from an analysis of said possible viral event.

### Claim at position 2
