Solution Overview
Problem
Conventional wireless network information acquisition methods consume excessive power due to the need for direct connection with access points, especially in mobile communication environments where unnecessary power is used to transmit signals over long distances.
Innovation Solution
A network information acquisition apparatus that includes a high power communication unit for connecting with an access point and a low power communication unit for receiving network information from nearby terminals, with a communication control unit managing the transition between these units to minimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile terminal connects directly with an access point to acquire network information, then network information can be obtained reliably, but power consumption increases significantly due to long-distance communication
Solution Approach 1:
The patent introduces nearby terminals as intermediary nodes to relay network information. Instead of directly connecting to the access point, a terminal first shares information with nearby terminals within short distance, which then forward the information further. This multi-hop relay approach reduces the communication distance for each individual transmission, thereby lowering power consumption while maintaining information acquisition reliability.
Solution Approach 2:
The patent segments the network information acquisition process into multiple stages: initial information sharing with nearby terminals at short distance, followed by progressive information forwarding to terminals at increasing distances. This segmentation of the communication path allows the system to achieve reliable information dissemination while minimizing the power consumption of individual transmission segments.
2Adaptability or versatility
If network information is transmitted from access points to all terminals, then complete network coverage is achieved, but unnecessary power is consumed by terminals at maximal communication distance
Solution Approach 1:
The patent implements preliminary action by having terminals first share network information with nearby terminals within short communication distance before expanding the dissemination range. This preliminary information sharing at close range establishes a foundation that reduces the need for high-power long-distance transmissions later, thereby preventing unnecessary power consumption while maintaining comprehensive network coverage.
Solution Approach 2:
The patent applies dynamics by enabling terminals to adapt their communication behavior based on their location and network conditions. Terminals dynamically adjust whether to act as information receivers or forwarders, and dynamically select communication partners based on distance and availability. This dynamic approach optimizes power consumption by activating long-distance high-power transmission only when necessary, while using low-power short-distance communication for routine information exchange.

AI summary
A network information acquisition apparatus is provided for acquiring network information related to a wireless network. The apparatus being located in a wireless network coverage area, which can receive network information related to a wireless network, from a base station of a wireless network, an access point, and another terminal which has already received network information and is located a short distance away, thereby minimizing a power consumption amount required for receiving network information.
