The invention discloses an indirect communication method, a relay node, a network device and a system, and relates to the field of communications. According to the invention, the problem that a terminal device cannot be recognized by the network side when the terminal device is accessed to the network at the identify of the relay node can be solved. The indirect communication method comprises thesteps of receiving a terminal device message from the terminal device by the relay node, encapsulating the terminal device message in a relay node message, indicating the encapsulated content in the relay node message as the terminal device message, sending the relay node message to a network selection device, receiving the relay node message by the network selection device, confirming a core network to which the terminal device belongs according to the terminal device identity information contained in the relay node message, sending the terminal device message to a first core network device corresponding to the core network to which the terminal device belongs, receiving the terminal device message by the corresponding first core network device, and carrying out the subsequent treatment on the terminal device message. The embodiment of the invention is applied to the indirect communication of the internet of things.
Description
technical field [0001] The present invention relates to the communication field, in particular to an indirect communication method, a relay node, a network device and a system. Background technique [0002] For 5G M-IoT (English full name: massive internet of things, Chinese full name: large-scale Internet of Things) scenarios or 4G NB-IoT (English full name: narrow band internet of things, Chinese full name: Narrowband Internet of Things) scenarios, A terminal device (for example, a terminal device) generally directly accesses a network to perform communication. When the network coverage is insufficient or for the consideration of reducing the power consumption of the terminal device, the terminal device may need to use other nearby relay nodes (such as mobile phone terminals or gateway devices) as relays to indirectly access the network for communication. Specifically, when the terminal device is first connected to the relay node through a short-distance connection method...
