When a device operating a communication application that features a custom application layer protocol for formatting messages for transmission cannot connect to the system hosting the application using a default protocol stack that include the custom application layer protocol, it instead connects using HTTP's chunked mode of transfer encoding. Each outgoing communication is encapsulated in a separate HTTP chunk, and communications to multiple different users may be conveyed via the one connection. Incoming communications (e.g., from the multiple users) are received as separate chunks and are unwrapped or de-encapsulated to retrieve the communication for presentation to a user.

A query of a database of organizations, categorized by location and purpose, determines the appropriate organization relevant to a user's location and incident type and generates a full report for review as geolocated on a map with the associated multi-media content. The method and system can also send an automatic message from an organization to a specific user in response to such user's post or request for assistance and establish a two-way communication between the user and the assigned organization based on the foregoing.
Machine learning based signal generation
The present disclosure uses input signals from different sources to fill gaps in the desired signal, for example a heat score signal. Different input signals are categorized so that they can be matched to a desired category of the desired signal. The various signals can be represented in vector format using category tags, for example. There are different latencies for each input signal that is aligned in time with the desired signal. Also, the match to the desired signal may vary from the input signals so that each desired signal's contribution during the gap is weighted accordingly. A composite signal is formulated from the time-adjusted and weighted input signals to fill the gap in the desired signal. Over time, the weighting and time-adjustment for each input signal can be modified with a learning algorithm that takes the approximation during the gap and compares it later with the actual data once the gap is filled in one embodiment.
