Abstract

RFC 6443 'Framework for Emergency Calling Using Internet Multimedia' describes how devices use the Internet to place emergency calls and how Public Safety Answering Points (PSAPs) can handle Internet multimedia emergency calls natively. The exchange of multimedia traffic typically involves a SIP session establishment starting with a SIP INVITE that negotiates various parameters for that session. In some cases, however, the transmission of application data is everything that is needed. Examples of such environments include a temperature sensors issuing alerts, or vehicles sending crash data. Often these alerts are conveyed as one-shot data transmissions. These type of interactions are called 'data-only emergency calls'. This document describes a container for the data based on the Common Alerting Protocol (CAP) and its transmission using the SIP MESSAGE transaction.
