Relay Terminal Paging Forwarding for Remote Device Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a challenge in ensuring the correct transmission of downlink data from a remote terminal to a network device, as the network device cannot directly communicate with the remote terminal, and effectively sending a paging message to the remote terminal to facilitate this transmission.
Innovation Solution
A wireless communication method where a network device sends an instruction message to a first terminal device to monitor a paging message of a second terminal device, allowing the network device to accurately send the paging message through the first terminal device, thereby ensuring the correct transmission of downlink data.

Engineering Contradiction Analysis
1Adaptability or versatility
If a relay terminal is used to transmit data for a remote terminal, then the remote terminal can communicate with the network device through the relay terminal, but the network device cannot directly communicate with the remote terminal, making it difficult to send paging messages to the remote terminal
Solution Approach 1:
The patent uses the relay terminal as an intermediary to forward paging messages to the remote terminal. The network device sends the paging message to the relay terminal, which then relays it to the remote terminal, solving the problem of indirect communication while maintaining reliable message delivery.
Solution Approach 2:
The patent implements a feedback mechanism where the relay terminal reports the link state information of the remote terminal to the network device. This feedback enables the network device to make informed decisions about paging message transmission, improving reliability by knowing whether the remote terminal is reachable through the relay.
2Reliability
If the network device sends paging messages through the relay terminal, then the remote terminal can be reached, but the link state information between the relay terminal and remote terminal must be accurately maintained
Solution Approach 1:
The relay terminal autonomously monitors and reports its own link state information to the network device without requiring complex centralized management. This self-service approach simplifies the overall system complexity while maintaining accurate link state information for reliable communication.
Solution Approach 2:
The relay terminal proactively reports link state information to the network device before paging messages need to be sent. This preliminary action ensures that the network device has up-to-date information about the remote terminal's accessibility, enabling reliable paging without complex real-time coordination.
3Reliability
If the relay terminal monitors paging messages for the remote terminal, then correct transmission can be ensured, but the relay terminal needs to be instructed by the network device on what to monitor
Solution Approach 1:
The relay terminal is designed with multi-functionality, serving both as a data transmission relay and as a paging message monitor. The network device sends a unified instruction that configures the relay terminal to monitor paging messages for specific remote terminals, simplifying operation while ensuring reliable transmission through the relay's inherent communication capabilities.

AI summary
Provided are a wireless communication method and a terminal device. A first terminal device sends a state update message to a network device, where the state update message is used for updating link state information of a link between the first terminal device and a second terminal device, the second terminal device communicating with the network device through the first terminal device. The network device receives the state update message from the first terminal device so as to update link state information of a link between the first terminal device and second terminal device.
