Unified HomeTalk Control Protocol (UHCP)

The UHCP introduces two new protocol layers implemented specified in XML. A common application layer is implemented for accessing all nodes across different control networks, which is called the node access layer. According to that layer each node accepts commands and sends back responses in a synchronous manner. Furthermore it sends notification messages asynchronously upon events.

The node access layer uses the node control interface (NCI) to send commands to a controllable device. The controller access layer is implemented below node access layer and it serves as a carrier for the NCI information elements. The controller access layer uses the controller command interface to deliver node commands to the HomeTalk control block. Apart from carrying node commands, the CCI allows a control client to take advantage of other resources and server functionalities such as browsing the home appliances or create macro commands.
