Lifts need to interact with applications through communication networks to provide different kinds of services to end users. In many cases, lifts cannot connect to communication networks directly. Therefore, gateways support the interconnection of such lifts with communication networks. Correspondingly, various lift companies applied their own data models and protocols. For this reason, interoperability problems have occurred. This Recommendation describes a framework of IoT based monitoring and management for lift with a protocol and data model to solve these problems.
