Network-Controlled Direct Terminal Communication in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks require terminals to route communication signals through base stations, even when terminals are physically close, leading to inefficient use of spectrum resources and increased network infrastructure usage.
Innovation Solution
Implementing network-controlled terminal-to-terminal direct communication within 3GPP technologies, allowing terminals to communicate directly without base station involvement, using static resources or network-controlled resource allocation, and incorporating proximity detection for handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If terminals communicate through base stations using conventional routing, then network infrastructure control and resource management are maintained, but spectrum resources are used inefficiently and network infrastructure usage increases
Solution Approach 1:
The patent extracts the communication path from the base station routing infrastructure, allowing terminals to establish direct peer-to-peer connections. This removes the unnecessary intermediate routing through base stations for local communications, thereby improving spectrum efficiency while reducing dependency on network infrastructure for such communications
Solution Approach 2:
The patent implements dynamic resource allocation where the network can control and switch between terminal-to-terminal direct communication and conventional base station routing based on conditions such as terminal proximity, resource availability, and communication requirements. This dynamic approach optimizes spectrum usage while maintaining network control
2Ease of operation
If static resources are dedicated for terminal-to-terminal direct communication, then terminals can communicate without network involvement, but resource flexibility and network control are reduced
Solution Approach 1:
The patent implements dynamic resource allocation where resources for terminal-to-terminal communication are not statically assigned but dynamically allocated and controlled by the network based on current conditions, terminal proximity, and communication requirements, maintaining both operational autonomy and resource flexibility
Solution Approach 2:
The patent incorporates network control mechanisms where the network receives feedback about terminal communications and resource usage, then adjusts resource allocation accordingly. This feedback loop ensures that resource allocation remains flexible and adaptable while still enabling terminal autonomy when conditions permit
3Loss of energy
If terminal-to-terminal direct communication is implemented, then spectrum resource efficiency improves, but resource allocation control complexity increases
Solution Approach 1:
The patent introduces the network as an intermediary that manages and controls resource allocation for terminal-to-terminal communications. The network entity coordinates resource distribution, monitors communication conditions, and makes allocation decisions, thereby simplifying the control complexity while maintaining spectrum efficiency benefits

AI summary
A terminal configured to operate in a mobile telecommunication network includes a receiver configured to receive from a network entity other than another terminal a direct communication initiation signal including resource allocation information for establishing terminal-to-terminal direct communication between the terminal and a second terminal using a radio access technology (RAT) in which the terminal is configured to communicate when communicating with the second terminal through one or more base stations or (e)NB and a terminal-end terminal-to-terminal direct communication logic configured to establish terminal-to-terminal direct communication with the second terminal based on the resource allocation information provided by the network entity other than a terminal.
