Transmission Apparatus Optimizing Data Transfer via Terminal Indices

The system changes transmission parameters (division transmission vs. redundancy transmission) based on the reliability index and capacity index of portable terminals. By dynamically adjusting transmission methods according to terminal parameters, the system achieves reliable information transmission while adapting to different terminal capabilities, thus resolving the contradiction between transmission reliability and control complexity.

The transmission control unit dynamically selects between division transmission and redundancy transmission based on real-time assessment of portable terminal indices. This dynamic adaptation allows the system to optimize transmission reliability for each terminal according to its specific characteristics, balancing reliability improvement with controlled complexity through automated decision-making.

The system segments information transmission into two distinct methods: division transmission that splits information across multiple terminals, and redundancy transmission that sends copies to ensure reliability. By segmenting the transmission approach based on terminal indices, the system achieves both high reliability through selective redundancy and high efficiency through optimized division transmission, resolving the contradiction between reliability and transmission efficiency.

The system applies different transmission qualities (redundancy level) to different portable terminals based on their specific reliability and capacity indices. High-index terminals receive division-transmitted partial information, while lower-index terminals receive redundancy-transmitted complete information. This localized quality adjustment optimizes overall transmission efficiency while maintaining information reliability.

The system prepares for potential information loss in division transmission by implementing redundancy transmission as a cushioning mechanism. When terminal reliability indices indicate risk, the system beforehand sends redundant complete information to ensure information completeness is maintained even when fast division transmission is used, thus resolving the contradiction between transmission speed and information completeness.

The transmission control unit acts as an intermediary that mediates between division transmission (for speed) and redundancy transmission (for completeness). Based on portable terminal indices, the intermediary selects the appropriate transmission method, ensuring that information is transmitted quickly when reliable and complete when necessary, thus balancing transmission speed with information completeness.

The transmission apparatus achieves multi-functionality by using portable terminals as intermediate relays, eliminating the need for dedicated wide area wireless communication hardware in the transmission apparatus. The portable terminals, which already possess wide area communication capabilities, serve the dual purpose of receiving information via short-distance wireless communication and transmitting it to the server, thus reducing device complexity while maintaining transmission directness.

The portable terminal acts as an intermediary between the transmission apparatus and the server, mediating the information transmission process. This intermediary approach allows the transmission apparatus to use simple short-distance wireless communication while still achieving direct server transmission through the terminal's wide area communication capability, thus resolving the contradiction between transmission directness and device complexity.
