PTX data analytic engine notifying group list of detected risk event

A method of operating a push-to-talk (PTT) system, the PTT system comprising a data analytics engine (DAE), the method comprising:

• receiving, by the DAE, a first signal from a first sensor;
• providing, by the DAE, analytics of the first signal based on the received first signal and a historical data of the first signal, wherein the analytics of the first signal comprises a first predicted risk indicator, wherein the first predicted risk indicator indicates a level of a security threat at a future time;
• detecting, by the DAE, a potential risk event by comparing the first predicted risk indicator and a first pre-determined risk threshold, wherein the first pre-determined risk threshold corresponds to a pre-determine level of security threat above which risk management sources are deployed;
• and
• notifying, by the PTT system, one or more client devices of the potential risk event, wherein the one or more client devices are in a group list of the PTT system.

A push-to-anything (PTX) system comprising:

• a data analytics engine (DAE), wherein the DAE is configured to:
• receive a first signal from a first source;
• calculate a first risk indicator using the first signal, the first risk indicator indicating a level of a first security threat;
• detect a risk event when the first risk indicator is above a first pre-determined risk threshold, the first pre-determined risk threshold corresponding to a pre-determine level of the first security threat above which an emergency response protocol is initiated;
• generate a first group list in response to detecting the risk event, wherein the first group list comprises one or more client devices of the PTX system;
• send the first group list to a PTX server of the PTX system, wherein the PTX server is configured to notify the one or more client devices in the first group list of the risk event;
• receive a second signal from a second source;
• calculate a second risk indicator using the second signal and a history record of the second signal, the second risk indicator indicating a predicted level of a second security threat at a future time;
• identify a potential risk event when the second risk indicator is above a second pre-determined risk threshold;
• generate a second group list comprising one or more client devices of the PTX system;
• and
• send the second group list to a push-to-talk (PTT) server of the PTX system, wherein the PTT server is configured to notify the one or more client devices in the second group list of the potential risk event.
