Embodiment

[0032] Such as figure 2 Shown, the u-UPnP architecture in the ubiquitous network. The ubiquitous devices in the ubiquitous network communicate through gateway nodes, and the gateway nodes are connected to control nodes, and identify and control the ubiquitous devices through the gateway nodes. Ubiquitous devices here refer specifically to sensing devices.

[0033] Such as image 3 Shown is the schematic diagram of the protocol system of ubiquitous network UPnP. From the control node to the gateway, the UPnP technology is used, which is based on the TCP / IP protocol stack. This technology is mature and widely used in the industry. From the gateway to the device, it uses a technology similar to UPnP, which is based on a specific private protocol stack. The following briefly introduces the protocol stack. The bottom four layers (PHY, MAC, NKW, APP) are the logical level description of the private protocol, and do not represent a specific protocol. It mainly describes the t...

Abstract

The invention discloses a method for realizing the universal plug and play (UPnP) of ubiquitous devices in a ubiquitous network. The ubiquitous devices in the ubiquitous network communicate through a gateway node, the gateway node is connected with a control node, and the ubiquitous devices are identified and controlled through the gateway node. According to the method, devices and services in the ubiquitous network are discovered by adopting a device and service discovery protocol (DSDP), the devices and the services are accessed and controlled by adopting an object access protocol (OAP), and the condition that the services of gateway-related ubiquitous devices are changed is notified by adopting a simple event notification protocol (SENP). The method has the advantages that an effective means for realizing the UPnP of the devices in the ubiquitous network is provided, the management complexity of the control node is reduced, and the efficiency of a ubiquitous-network UPnP technology is increased.

Description

technical field [0001] The invention belongs to the technical field of ubiquitous network communication, and in particular relates to a method for realizing universal plug and play of ubiquitous devices in a ubiquitous network. Background technique [0002] With the development of industrial technology, the types of electronic devices (such as smart devices, wireless devices, and personal computers, etc.) continue to increase. People hope to interconnect these devices through the network and centrally control them by designated control nodes. In this context, Microsoft and some device manufacturers have proposed Universal Plug and Play (UPnP) technology. Such as figure 1 As shown, UPnP technology includes the entire network and realizes the discovery and control of network devices and services, such as network printers, Internet gateways and consumer electronic devices. UPnP aims to realize a "zero" configuration and "invisible" networking process, and automatically discov...
