Description

The present invention relates to the field of communications, and in particular to a method and apparatus for controlling a home network device. BACKGROUND The Universal Plug and Play (UPnP) protocol is a protocol developed by the UPnP organization to share content in a home network. In the UPnP protocol, the advantages of the home network can be fully utilized to share media content located on different devices with other UPnP devices. The home network device can be classified into three types: a media server (Media Server, abbreviated as MS), a media controller (Media Controler, abbreviated as MC), and a media renderer (MR). The media server is used to provide sharing of media content for the home network. The media server mainly includes the following services: Connection Manager Service (CMS), Content Directory Service (CDS), and Audio Transport Service (AVT). The connection management service is used to establish a network connection between the media controller and the media server; the content directory service is used to manage the media data in the media server; the audio and video transmission service is used to control the media data transmission between the media controller and the media server. . The media controller is used to manage other media server devices and media renderer devices in the home network. When a media server and a media renderer join or exit the UPnP network, the media controller can update the device list in time; the media controller device also needs to support browsing the media content shared by the media server, and can specify the media renderer device to play and play. Processes can be controlled by the media controller. The media renderer is used to render media content acquired in the home network. The media renderer mainly includes the following services: Rendering Control Service (RCS), connection management service, and audio and video transmission service. The connection management service is used to implement media media protocol and media format negotiation with the media server; the audio and video transmission service is used to implement the control of the playback process; and the rendering control service is used to implement control of the rendering characteristics, such as brightness, contrast, and Volume, etc. Media servers, media controllers, and media renderers can be used individually or integrated.

For example, in a practical application, when the home network device is one of the following: a media server, a media renderer, and a media controller, the following implementation manners may be adopted: When there is a media server device or a media renderer device in the home network, The SSDP NOTIFY broadcast message may be sent through the 239.255.255.250: 1900 address (ie, the predetermined address mentioned above), and the control terminal (in an actual application, may be operated by the media controller of the control terminal) receives the SSDP NOTIFY broadcast message. The LOCATION field is extracted, and the URL included in the field is accessed by the HTTP GET method (that is, the predetermined manner) to obtain the description information of the media server device or the media renderer device, where the description information includes the IP address. Information and device type information. The media controller of the control terminal updates the device list information of the home network device located at the control terminal according to the IP address information and the device type information. When the media server device or media renderer device exits, the SSDP NOTIFY broadcast message can also be sent via the 239.255.255.250: 1900 address. After receiving the message, the media controller of the control terminal confirms that the media server device or the media renderer device has left the network, and timely updates the device list information of the home network device located in the control terminal. When the media controller accesses the home network, the SSDP M-SEARCH message can be sent through the 239.255.255.250: 1900 address (that is, the predetermined address mentioned above) to control the terminal (in actual applications, the media server of the control terminal can perform operations) After receiving the message, the device type restriction of the ST field in the M-SEARCH message may be ignored, and a response message is sent in response to the SSDP M-SEARCH message, and the response message is carried in the response message. LOCATION field, which is mainly used to save the URL of the description information of the control terminal. After receiving the response, the media controller extracts the URL of the LOCATION field from the response message, and accesses the URL by using the HTTP GET method (that is, the predetermined method described above). When the media server of the control terminal finds that another device obtains its description information by accessing the URL, the server controlling the terminal saves the IP address information of the access device, and determines that the media type information of the access device is the media controller type. After obtaining the device description information, the media controller can control the media server of the terminal through a General Event Notification Architecture (GENA) subscription (SUBSCRIBE). When the media controller exits the home network, the subscription can also be cancelled via GENA UNSUBSCRIBE. When the media server of the control terminal finds that other devices cancel the subscription, it can confirm that the device has left the network, and timely update the device list information of the home network device located in the control terminal. Moreover, the control terminal can also actively control the exit of the DLNA device (mainly the home network device). When the control terminal wants a home network device to exit the home network, it only needs to send the IP address of the home network device to the access node (AP) device in the home network, and send a disconnect message to the AP device. For the convenience of the implementation, a listening module can be run on the AP device side. The listening module is mainly used to listen to the disconnection message sent by the control terminal and forward it to the processing module of the AP device. After receiving the disconnection message, the processing module completes the connection between the home network device corresponding to the disconnected IP address information and the home network according to the IP address information. Through the above method, the user can manage the DLNA device in the home network, and can arbitrarily control the exit of the DLNA device. The above method will be described in detail below with reference to FIGS. 2 to 5 and a preferred embodiment. 2 is a flow chart of a media server/media renderer accessing and exiting a home network according to a preferred embodiment of the present invention.

5302. After receiving the broadcast message of the device C, the control terminal B ignores the request of the ST field in the M-SEARCH message, and generates a response message to the unicast response of the M-SEARCH message. S303. After receiving the response message, the device C extracts the URL information of the LOCATION field.

5304. The device C accesses the URL through the HTTP GET mode (that is, the foregoing predetermined manner), and obtains the device description information of the control terminal B.

5305. The control terminal B discovers that another device accesses the description information, saves the IP address of the device, and the default device type is a media controller, and updates the device list of the control terminal. S306, the device C subscribes to the control terminal B by using the GENA SUBSCRIBE mode (the UNSUBSCRIBE message is an exit message).

S307, Device C exits the home network and cancels the subscription by GENA UNSUBSCRIBE. S308. After receiving the UNSUBSCRIBE message, the control terminal B confirms that the device exits the home network, and updates the device list information of the DLNA device (mainly the home network device) on the control terminal. 4 is a flowchart of controlling a home network device to exit a home network according to a preferred embodiment of the present invention.
