Method, system for accessing home network device and home network access device

A method for accessing a home network, comprising:

• finding, by a home network access device, a home network device, and obtaining information of the home network device through a home network protocol;
• establishing, by the home network access device, a data model of the home network device in the home network access device according to the information of the home network device, so that a remote service device accesses the data model of the home network device through a remote management protocol;
• and
• constructing, by the home network access device, a home network protocol packet according to management information set by the remote service device in the established data model of the home network device through the remote management protocol, and sending the home network protocol packet to the home network device;
• wherein the established data model of the home network device further comprises device information objects, and service information objects which are a next level of the device information objects,
• the device information objects further comprise device information parameters;
• the service information objects further comprise control command information parameters, and the service information objects comprise out parameter information,
• wherein the setting, by the remote service device, the management information in the established data model of the home network device through the remote management protocol comprises:
• setting, by the remote service device, the management information in the control command information parameters of the data model through a remote procedure call (RPC) method,
• wherein the constructing, by the home network access device, the home network protocol packet according to the setting comprises:
• constructing, by the home network access device, the home network protocol packet corresponding to a control command according to control command information of the data model, and setting the out parameter information,
• after the sending the home network protocol packet to the home network device, the method further comprises:
• accepting the remote service device obtaining the out parameter information in the service information objects through the RPC method;
• the service information objects comprise event subscription information and state information;
• and
• after establishing the data model of the home network device, the method further comprises:
• accepting, by the home network access device, the remote service device setting the event subscription information through the RPC method;
• changing, by the home network access device, the state information in the data model according to a state change event message of the home network device after obtaining the state change event message, and notifying state change information of the home network device to the remote service device through the remote management protocol.
