Terminal P2P Communication Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WCDMA mobile telecommunication systems, terminals face challenges with expensive roaming services when communicating with different providers and lack of base station coverage, which existing solutions attempt to address by adding short-range communication modules, increasing costs.
Innovation Solution
A terminal with a transceiver capable of peer-to-peer (P2P) communication, including a transmission module, reception module, receive channel measurer, and communication mode controller, allows direct P2P communication between adjacent terminals when short-range communication is possible, switching between base station and P2P modes based on signal intensity, and stores communication records for billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal uses base station communication mode, then communication coverage is extended, but communication cost increases due to roaming services
Solution Approach 1:
The terminal dynamically switches between base station communication mode and P2P communication mode based on real-time conditions. When base station coverage is unavailable or roaming costs are excessive, the terminal automatically transitions to P2P mode with adjacent terminals, creating a flexible adaptive system that optimizes both coverage and cost.
Solution Approach 2:
Adjacent terminals act as intermediaries to relay communication when base station coverage is unavailable. The P2P communication mode allows terminals to function as intermediate nodes, extending coverage indirectly while avoiding direct base station roaming charges.
2Adaptability or versatility
If a terminal adds short-range communication module, then P2P communication capability is enabled, but terminal cost increases
Solution Approach 1:
The existing transceiver in the terminal is made multi-functional by enabling it to operate in both base station communication mode and P2P communication mode. This eliminates the need for separate short-range communication modules while maintaining full P2P capability, thus reducing terminal cost.
Solution Approach 2:
The patent merges the P2P communication function with the existing base station communication transceiver. By combining both functions into a single transceiver system, the patent eliminates the need for additional dedicated short-range communication hardware, thereby reducing terminal cost.
3Loss of energy
If a terminal switches to P2P communication mode, then base station resources are conserved, but communication reliability may be affected
Solution Approach 1:
The terminal continuously monitors communication conditions and feedback signals to determine when to switch between modes. This feedback mechanism ensures that P2P communication is only activated when necessary, maintaining communication reliability by falling back to base station mode when conditions deteriorate.

AI summary
A terminal supporting peer-to-peer (P2P) communication, wherein a transceiver of the terminal is implemented to support P2P communication with an adjacent terminal in the same cell. Thus, when short-range communication is possible, the terminal performs P2P communication directly with the adjacent terminal, not via a base station. Consequently, when terminals use different mobile telecommunication service providers or there is no base station network, the terminals can be used for short-range communication. More particularly, when a receiving channel state becomes satisfactory while communication with an adjacent terminal is being performed via a base station, the terminal directly switches to a P2P communication mode and performs communication with the adjacent terminal. On the contrary, when the receiving channel state deteriorates while communication with the adjacent terminal is being performed in the P2P communication mode, the terminal directly switches to a base station communication mode and performs communication with the adjacent terminal.
