Attachment method and communication method of Internet of Things terminal and corresponding system

Abstract

The invention relates to an attachment method and a communication method of an Internet of Things terminal and a corresponding system. The attachment method of the Internet of Things terminal comprises the following steps: RAN equipment receives an attachment request from the terminal, wherein the attachment request comprises a subnet identifier of a subnet to which the terminal belongs and a terminal identifier; the RAN equipment forwards the attachment request to a mobile management entity; the mobile management entity sends an attachment success response to the terminal through the RAN equipment; the mobile management entity subnet control module stores the identifier of the RAN device attached to the terminal, the identifier of the subnet to which the terminal belongs, and the identifier of the terminal. In the communication method of the Internet of Things terminal, a sub-network control module of a mobile management entity compares information in a received service request with stored information, and judges whether a sender terminal and a receiver terminal are users of the same sub-network and are both attached to the same RAN device; if yes, the RAN equipment subnet control module pages the receiver terminal in the RAN and forwards the service flow in the RAN, and low-delay communication between objects of the 6G network is achieved.

Description

technical field [0001] The present invention relates to the field of 6G mobile communication, and more specifically relates to an attachment method and a communication method of an Internet of Things terminal and a corresponding attachment system and communication system. Background technique [0002] 2-5G focuses on the communication between people and people, and between people and machines, in order to solve the problem of the Internet of Everything. The 6G network will pay more attention to the goal of interconnecting all things through user self-organizing networks and operator networks. How to realize the ultra-low latency communication requirements between things has become one of the research focuses of 6G networks. Under the 2-5G network, once the RAN (service access network) equipment receives the service request initiated by the terminal side, it will directly forward it to the core network, and the communication between users must be transferred through the core...

AI Technical Summary

Problems solved by technology

At present, the core network tends to be more and more centralized. Since the communication between users under the same RAN must also go through the centrally deployed core network, this greatly increases the communication delay, so it cannot meet the requirements of ultra-low time between things.
