HOME NETWORK SYSTEM TO WHICH A LIVING NETWORK CONTROL PROTOCOL IS APPLIED, PARTICULARLY FOR PERFORMING A CONTROL COMMAND OF REMAINING FIELDS OF A REQUEST MESSAGE ACCORDING TO A VALUE OF SOME FIELDS OF THE REQUEST MESSAGE TO EFFECTIVELY PROCESS THE MESSAGE

摘要

PURPOSE: A home network system is provided to perform a control command of remaining fields of a request message according to a value of some fields of the request message and a current operational state of a device, and perform plural controls on a device by using a request message including plural control commands. CONSTITUTION: A home network(1) and a client device(4) are connected to an LnCP(Living network Control Protocol) server(3) through the Internet(2). The LnCP server(3) receives a monitoring and control command from the client device(4) and transmits a corresponding message of a certain form to the home network system(1) through the Internet(2). In addition, the LnCP server(3) receives a certain form of message from the home network system(1), and stores it or transmits it to the client server(4). A home gateway(10) performs a function of connection with the Internet(2). Network managers(20-23) perform a function of setting and managing an environment of electric devices(40-49). LnCP routers(30,31) are provided to connect transmission media. LnCP adapters(35,36) allow the network manager(22) and the electric device(46) to be connected with the transmission media. The home network system(1) includes a plurality of electric devices(40-49). The first electric device generates a request message including a certain operational command and sends it to the second electric device. Then, the second electric device reads a certain option value field of the request message and performs a control command included in other remaining fields than the option value field according to the option value field.
