Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for discovering resources.
Background
The data communication between the devices is suitable for scenes such as traffic control management, remote meter reading, remote monitoring, medical monitoring, intelligent home control and the like. In order to implement data communication between devices, a service provider provides a service platform to a device or a device gateway on a user side, and the device on the user side accesses the service platform directly or through one or more device gateways. The general service function module in the service platform and the general service function module in the user side equipment or the equipment gateway carry out data communication through the established data channel. In the above system, the data communication is based on a registration relationship, that is, only when a device is registered in the device gateway or another device, the former sends a message, and the latter directly sends the message, but not to other devices. However, in the above system, the message sent by the device is routed to the service platform, and when the subsequent service platform forwards the message to the device/device gateway, the next hop of the message cannot be determined based on the registration relationship, because the service platform is not registered to another device/device gateway.
Under the current internet of things standardization organization OneM2M architecture, resource discovery (discovery) is limited to a single device. I.e. the application on device a can only retrieve the required resource on device a or send a request message to device B requesting discovery of a certain resource on device B, but the request message may be a hypertext transfer protocol http based request message, where http needs to explicitly specify a particular resource, e.g. a specific photo name, or to save an address of a particular resource, e.g. an internet protocol address of the particular resource. But cannot achieve simultaneous retrieval of either device a or device B. Therefore, a method for discovering resources is needed to solve the above technical problems in the prior art.
