AI Technical Summary

Technical Problem

RFID technology is limited to small-scale and short-range scenarios, leading to increased costs and reduced communication effectiveness in large-scale, wide-range, and large-coverage environments.

Method used

A relay device communicates with a core network element via a radio access network device to obtain and transmit identifiers of terminal devices within its coverage area, facilitating communication between terminal devices and network devices in high-coverage, large-scale, and wide-area scenarios.

Benefits of technology

Enables effective communication between terminal devices and network devices in large-scale and wide-range scenarios by using a relay device to manage and transmit identifiers, supporting inventory and management operations.

Abstract

The present application provides a communication method and apparatus. A relay device can communicate with a core network element through a first radio access network device, so that the relay device can obtain an identifier of a terminal device within the coverage area of ​​the relay device and transmit the identifier to a first access and mobility management function network element through the first radio access network device. In this way, communication between a terminal device and a network device can be achieved in scenarios where the indoor coverage of a 5G network is weak and where the uplink signal of an RFID terminal device is weak, and communication between a terminal device and a network device can also be achieved in large-coverage, large-scale, and wide-area scenarios.
