Control Point Information Guidance via Direct Wireless Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information guidance services rely on data service traffic consumption and positioning accuracy, which can be inefficient and unreliable, wasting time and energy for users seeking specific information.
Innovation Solution
A point-to-point communication method where a control point sends a connection request to a user equipment with a guidance identifier, allowing the user to select and receive detailed information, independent of data service traffic or positioning accuracy, using protocols like WiFi Direct or Bluetooth for direct device-to-device communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information guidance services use Internet or positioning function, then information can be sent to user equipment, but data service traffic consumption increases and positioning accuracy is required
Solution Approach 1:
The patent introduces a wireless communication device as an intermediary between the information source and user equipment. This intermediary establishes a direct wireless connection (using protocols like WiFi Direct or Bluetooth) to transmit guidance information, eliminating the need for Internet data traffic and positioning services. The intermediary device receives guidance information and forwards it directly to the target user equipment through peer-to-peer communication.
2Reliability
If information guidance services use Internet or positioning function, then information can be sent to user equipment, but positioning accuracy must be maintained
Solution Approach 1:
The patent extracts the positioning function from the information guidance system entirely. Instead of relying on positioning services to deliver information to user equipment, the system uses direct wireless communication between devices. The guidance information is transmitted through established wireless connections without needing to determine or verify the precise location of the user equipment.
3Loss of information
If users search for information using paper or electronic file guidance, then information can be found, but time and energy are wasted
Solution Approach 1:
The patent implements a push-based information delivery system where guidance information is automatically sent to user equipment through direct wireless communication. Users don't need to actively search for information through paper maps or electronic files; instead, the relevant guidance information is delivered directly to their devices, eliminating the time and energy spent on manual information searching.

AI summary
Embodiments of the present invention disclose an information sending method, device, and system, which are applied in the field of communications technologies. In the embodiments of the present invention, a control point sends a connection request to a target user equipment, where the connection request includes a guidance identifier, so as to request the target user equipment to receive detail information sent by the control point; after displaying the guidance identifier to a user and receiving a guidance identifier selected by the user, the user equipment sends a connection request acceptance message to the control point; and the control point may send detail information that corresponds to the guidance identifier to the target user equipment, where the guidance identifier is selected by the user and included in the connection request acceptance message, thereby implementing information guidance for the user by the control point.
