总体而言，家庭主网关要起到三个功能： In general, the home main gateway has three functions:
1)Internet接入功能，包括路由、NAT等等； 1) Internet access functions, including routing, NAT, etc.;
2)家庭网络中各种不同通信协议之间的转换，以及家庭网络系统于TCP/IP协议之间的转换。 2) Conversion between various communication protocols in the home network, and conversion of the home network system between TCP/IP protocols.
3)运行家电管理软件，将使用不同通信协议的家用电器都接入到家庭网络中，并统一管理起来； 3) Run the appliance management software to connect the household appliances using different communication protocols to the home network and manage them in a unified manner;
家庭网关就其功能分类，可以分为： The home gateway is classified into its functions and can be divided into:
1)家庭主网关。主网关与家庭主网中的设备互联，实现对家庭主网的配置和管理，同时作为家庭服务器被内部设备和外部网络访问。 1) Home main gateway. The primary gateway is interconnected with the devices in the home network to implement configuration and management of the home network, and is accessed as a home server by internal devices and external networks.
2)家庭控制子网关。家庭控制子网关与家庭控制子网中的设备互联，实现对家庭控制子网的配置和管理，同时为家庭控制子网内的各种设备提供与家庭主网的接口，使各种子网设备可以获得各种基于家庭主网的服务。 2) Home control sub-gateway. The home control sub-gateway is interconnected with the devices in the home control subnet to implement configuration and management of the home control subnet, and provides an interface with the home main network for various devices in the home control subnet to enable various subnet devices. A variety of home based network-based services are available.
基于上述以网关为中心的设备互发现方法，主要分为以下几个步骤实现： Based on the above-mentioned gateway-centric device mutual discovery method, it is mainly divided into the following steps:
1）家庭控制子网关使用'简单服务发现协议'(SSDP)在家庭网络上搜索感兴趣的设备，一旦收到搜索请求，该设备就检查该搜索条件以确定它们是否匹配。如果匹配，一个单播SSDP响应就被发送到该家庭控制子网关。同时，设备也使用SSDP向其他设备或家庭控制子网关宣告其在家庭网络上的存在，并通知它所支持的服务。SSDP定义了网络服务如何在网络上被发现，在设备和家庭网关之间交换的信息只限于一些发现信息，它们提供关于设备及其服务的基本信息，还带有一个说明URL，后者可用来获得设备的其他信息。 1) The Home Control Sub-Gate uses the Simple Service Discovery Protocol (SSDP) to search for interested devices on the home network, and upon receiving a search request, the device checks the search criteria to determine if they match. If matched, a unicast SSDP response is sent to the home control sub-gateway. At the same time, the device also uses SSDP to announce its presence on the home network to other devices or home control sub-gates and informs it of the services it supports. SSDP defines how network services are discovered on the network. The information exchanged between the device and the home gateway is limited to some discovery information. It provides basic information about the device and its services, along with a description URL, which can be used. Get additional information about the device.
2)通过使用在步骤1）中获得的URL，家庭控制子网关可接收到关于设备的XML格式信息，如制造商、型号和序列号。XML是UPnP的核心部分，被用在设备和服务描述、控制消息和事件处理中。另外，获得用于访问设备功能的URL列表。 2) By using the URL obtained in step 1), the home control sub-gateway can receive XML format information about the device, such as manufacturer, model number and serial number. XML is a core part of UPnP and is used in device and service descriptions, control messages, and event processing. In addition, a list of URLs for accessing device functions is obtained.
3)使用步骤2）获得的URL，家庭控制子网关可以访问附加的XML格式信息，此信息说明设备服务可对哪些操作做出响应，同时包含各种操作的参数。控制消息采用XML格式，使用的是'简单对象访问协议'(SOAP)。UPnP采用SOAP向设备发送控制消息并将结果或错误返回到家庭控制字网关。每个UPnP控制请求都是一个SOAP消息，都包含调用操作和一组参数。其响应也是SOAP消息，其中包括状态、返回值以及任何返回参数。 3) Using the URL obtained in step 2), the home control sub-gateway can access additional XML format information indicating which operations the device service can respond to, while including parameters for various operations. Control messages are in XML format using the Simple Object Access Protocol (SOAP). UPnP uses SOAP to send control messages to the device and returns the results or errors to the home control word gateway. Each UPnP control request is a SOAP message, which contains the call operation and a set of parameters. Its response is also a SOAP message, including the status, return value, and any return parameters.
4)家庭控制子网关预定一项服务，则该服务将向家庭控制子网发送时间消息，宣布设备状态的改变。事件消息采用XML格式，而且使用的是'通用事件通知结构'(GENA)。 4) If the home control sub-gate subscribes to a service, the service will send a time message to the home control subnet to announce the change of the device status. The event message is in XML format and uses the 'Generic Event Notification Structure' (GENA).

S202：智能家居设备接收到搜索请求，并根据搜索条件确定是否与家庭控制子网关所匹配，如果智能家居设备匹配成功，则发送单播SSDP响应在数字家庭网络设备中传播； S202: The smart home device receives the search request, and determines whether it matches the home control sub-gate according to the search condition. If the smart home device matches successfully, sending the unicast SSDP response to be transmitted in the digital home network device;
S203：第一家庭控制子网关接收SSDP响应消息，解析SSDP消息中URL的XML格式信息获取访问智能家居设备的URL列表； S203: The first home control sub-gateway receives the SSDP response message, and parses the XML format information of the URL in the SSDP message to obtain a URL list for accessing the smart home device.
S204：第一家庭控制子网关采用简单对象访问协议SOAP将所述获取的URL列表发送到数字家庭网络上的各个家庭控制子网关。 S204: The first home control sub-gateway sends the obtained URL list to each home control sub-gateway on the digital home network by using a simple object access protocol SOAP.
需要说明的是，这里的数字家庭网络设备间采用SOAP发送控制协议消息，或者采用SOAP反馈协议消息。家庭网络设备在数字家庭网络中预定一项服务后，则向数字家庭网络中的数字家庭子网关发布事件消息，宣布智能家居设备的改变状态。该事件消息采用XML格式，使用的是通用事件通知结构GENA。 It should be noted that the digital home network devices here adopt SOAP transmission control protocol messages or adopt SOAP feedback protocol messages. After the home network device subscribes to a service in the digital home network, it issues an event message to the digital home sub-gateway in the digital home network to announce the change status of the smart home device. The event message is in XML format using the generic event notification structure GENA.

S302：智能家居设备接收到搜索请求，并根据搜索条件确定是否与家庭控制子网关所匹配，如果智能家居设备匹配成功，则发送单播SSDP响应在数字家庭网络设备中传播； S302: The smart home device receives the search request, and determines whether it matches the home control sub-gate according to the search condition. If the smart home device matches successfully, sending the unicast SSDP response to be transmitted in the digital home network device;
S303：家庭主网关接收SSDP响应消息，解析SSDP消息中URL的XML格式信息获取访问智能家居设备的URL列表； S303: The home master gateway receives the SSDP response message, and parses the XML format information of the URL in the SSDP message to obtain a URL list for accessing the smart home device.
S304：家庭主网关采用简单对象访问协议SOAP将所述获取的URL列表发送到数字家庭网络上的各个家庭控制子网关。 S304: The home master gateway sends the obtained URL list to each home control sub-gateway on the digital home network by using a simple object access protocol SOAP.
需要说明的是，这里的数字家庭网络设备间采用SOAP发送控制协议消息，或者采用SOAP反馈协议消息。家庭网络设备在数字家庭网络中预定一项服务后，则向数字家庭网络中的数字家庭子网关发布事件消息，宣布智能家居设备的改变状态。该事件消息采用XML格式，使用的是通用事件通知结构GENA。 It should be noted that the digital home network devices here adopt SOAP transmission control protocol messages or adopt SOAP feedback protocol messages. After the home network device subscribes to a service in the digital home network, it issues an event message to the digital home sub-gateway in the digital home network to announce the change status of the smart home device. The event message is in XML format using the generic event notification structure GENA.
