Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile network architectures are not optimized for Machine to Machine (M2M) communication, leading to inefficiencies and increased operational complexity, particularly in managing direct Device to Device (D2D) communication, including decisions on spectrum usage and relay requirements.
Innovation Solution
A method and system where a network side device determines whether User Equipments (UEs) meet conditions for direct D2D communication, configuring resources accordingly, and switches between direct D2D, relay-based D2D, and architecture communication modes based on proximity and capabilities, reducing network load and dependence.

Engineering Contradiction Analysis
1Productivity
If direct D2D communication is implemented between UEs, then network load is reduced, but network control and management capability is weakened
Solution Approach 1:
The network side device acts as an intermediary that coordinates and manages D2D communication between UEs. It determines whether UEs meet direct D2D communication conditions, configures appropriate resources, and switches communication modes as needed, thereby maintaining network control while enabling direct UE communication to reduce network load.
Solution Approach 2:
The communication mode between UEs is made dynamic rather than static. The network side device continuously monitors UE conditions and switches between direct D2D communication, relay-based D2D communication, and architecture communication modes based on real-time proximity and capability assessments, optimizing network load management while maintaining control.
2Reliability
If licensed spectrum is used for D2D communication, then network management and control are maintained, but resource scheduling complexity increases
Solution Approach 1:
The resource allocation process is segmented into distinct communication modes (direct D2D, relay-based D2D, and architecture communication). The network side device configures resources specifically for each mode based on UE conditions, simplifying the overall resource scheduling complexity while maintaining reliable network management through mode-specific resource allocation.
3Area of stationary object
If relay-based D2D communication is implemented, then coverage is extended, but communication delay increases
Solution Approach 1:
The system dynamically switches between direct D2D communication mode (for low delay when UEs are in proximity) and relay-based D2D communication mode (for extended coverage when UEs are out of proximity). The network side device makes real-time mode decisions based on UE proximity and capability, optimizing the trade-off between coverage area and communication delay.

AI summary
A method and a system for communication between devices in proximity, a network side device and a User Equipment (UE) are disclosed. The method includes that: a network side device determines whether UEs meet a direct Device to Device (D2D) communication condition; when the network side device determines that the UEs meet the direct D2D communication condition, the network side device informs the UEs of the result of the determination, and configures resources for direct D2D communication for the UEs according to requirements of the UEs; and when the network side device determines that the UEs do not meet the direct D2D communication condition, the network side device configures resources for architecture communication for the UEs according to the requirements of the UEs. The disclosure can implement D2D communication between devices in proximity, reduce network load and relieve the dependence of the D2D communication on a network.
