Wi-Fi Beacon Frame Service Information Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi service information systems require users to access the network to receive service information, leading to low pushing efficiency, particularly for advertisements.
Innovation Solution
A method where a radio access point broadcasts service information in beacon frames according to the 802.11 protocol, allowing terminals to receive information without accessing the network, using indicators and parameters to control and identify service information within the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal side software is developed to enable automatic connection to Wi-Fi network, then service information can be obtained from server, but user must access the network which reduces pushing efficiency
Solution Approach 1:
The patent extracts service information from the network access process by embedding it in beacon frames that are broadcast independently of user authentication or network connection status. This separates the information delivery function from the network access requirement, allowing terminals to receive service information without completing network access procedures.
Solution Approach 2:
The access point performs preliminary action by embedding service information in beacon frames before any user authentication or network access occurs. The information is prepared and broadcast in advance during the beacon transmission phase, which happens continuously regardless of user connection status, enabling immediate delivery without waiting for network access completion.
2Loss of information
If login page with service information is used, then information can be displayed, but user must complete network access which reduces pushing efficiency
Solution Approach 1:
The patent extracts service information from the login page context and embeds it directly in beacon frames. This removes the dependency on users viewing a login page or completing authentication, allowing the same information to be delivered through the beacon frame mechanism independently of user interaction with network access interfaces.
Solution Approach 2:
The beacon frame serves as an intermediary carrier that transports service information from the access point to terminals without requiring user interaction with login pages. The beacon frame mechanism acts as a mediator that delivers information through a different channel (broadcast wireless frames) bypassing the traditional login page interface.
3Productivity
If service information is embedded in beacon frames, then terminals can receive information without network access, but beacon frame structure must be modified
Solution Approach 1:
The beacon frame structure is designed to serve multiple functions: traditional network synchronization and timing functions, plus carrying service information. By making the beacon frame multi-functional, the patent avoids creating entirely new message structures and instead extends the existing beacon frame format to include information elements for service data, reducing overall system complexity.
Solution Approach 2:
Service information is nested within the beacon frame structure as information elements. The patent embeds service information containers inside the existing beacon frame format, allowing the information to be carried within the established protocol structure rather than requiring separate transmission mechanisms, thus minimizing structural complexity changes.

AI summary
Embodiments of the present invention disclose a service information pushing and receiving method, and a related apparatus and system. The service information pushing method includes: obtaining, by a radio access point AP, service information provided by a service provider, adding the service information to a beacon frame, and broadcasting the beacon frame. A method for receiving pushed service information includes: obtaining, by a terminal, a beacon frame that carries service information, and extracting and outputting the service information in the beacon frame. The technical solution provided by the present invention enables a terminal to receive service information in a Wi-Fi network without accessing the network.
