Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems support a limited number of connections and are not well-equipped to handle multi-hop relays, leading to inefficiencies and potential compatibility issues when remote terminals with single-hop relay capabilities attempt to access multi-hop relay networks.
Innovation Solution
A method and terminal design that includes sending and receiving relay state information to determine and ensure compatibility between terminals, preventing single-hop capable terminals from accessing multi-hop relay networks, thereby improving communication quality and reducing unnecessary network access operations.

1Area of stationary object
If traditional single-hop relay terminals are allowed to access multi-hop relay networks, then network coverage is expanded, but communication reliability deteriorates due to compatibility issues and inefficient signaling interactions
Solution Approach 1:
The patent applies preliminary action by having the relay terminal send relay state information before the remote terminal initiates connection. This advance notification allows the remote terminal to assess compatibility and decide whether to attempt connection, preventing unreliable signaling interactions from occurring in the first place.
Solution Approach 2:
The patent implements feedback through the relay state information mechanism, where the relay terminal provides status information about its relay capabilities and state to remote terminals. This feedback loop enables remote terminals to make informed decisions about connection attempts, improving overall communication reliability by avoiding incompatible connections.
2Reliability
If relay state information exchange is implemented, then communication reliability is improved, but device complexity increases due to additional signaling protocols
Solution Approach 1:
The patent applies universality by designing the relay state information to serve multiple functions simultaneously: it indicates relay capability status, provides compatibility information, and enables connection decision-making. This multi-functionality reduces the need for separate signaling protocols, thereby limiting the increase in device complexity while maintaining improved reliability.
