1. the application of the internet of things needs to be simultaneously connected with a video management platform and a household appliance management platform in a butt joint mode. For example: the smart home application needs to be integrated with interfaces of multiple internet of things platforms in a butt joint mode, and the development cost of the smart home application is high. Fig. 2A is a schematic diagram of an internet of things application controlling different types of internet of things devices.

2. Different types of internet of things equipment are uniformly accessed into one internet of things platform, because the access protocol and the standard of each internet of things platform are not uniform, the different types of internet of things equipment need to adapt to different protocol access modes, and for internet of things equipment manufacturers, a plurality of internet of things platforms need to be docked, and the access cost is very high. Fig. 2B is another schematic diagram of an application of the internet of things controlling different types of devices of the internet of things.

The problem that when the internet of things application developers and the internet of things equipment developers described above provide complete solutions for the internet of things, the interfaces and protocols of multiple internet of things platforms need to be adapted, and the implementation complexity is very high is solved. According to the solution provided by the application, through communication between the local IoT platform and the third-party IoT platform, the Internet of things equipment accessed by the third-party IoT platform is brought into the local IoT platform for unified management, and differences among different Internet of things platforms are shielded, so that an Internet of things application manufacturer can develop once to interface one IoT platform (which can be called as the local IoT platform) and access more types of Internet of things equipment.

Specifically, a Platform Access Gateway (PAG) service can be introduced, the internet of things devices accessed by the third-party IoT platform can be conveniently and quickly integrated into the local IoT platform, and can be opened to the internet of things application without difference, so that the internet of things devices accessed by the local IoT platform and the internet of things devices accessed by the third-party IoT platform can be managed without difference. For the internet of things equipment, the corresponding default IoT platform (which can be called as a third-party IoT platform) is directly docked, so that the access cost of an internet of things equipment manufacturer and an internet of things application manufacturer is reduced.

It should be noted that, in this embodiment of the application, the internet of things device accessed by the third party IoT platform may be referred to as a third party internet of things device for short, the identifier of the third party internet of things device may be referred to as a third party identifier (3rd ID) for short, the internet of things device accessed by the local IoT platform may be referred to as a local internet of things device for short, and the identifier of the local internet of things device may be referred to as a local identifier (local ID) for short.
