Interworking Information Broker for Wireless LAN Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless LAN systems face inefficiencies in processing interworking information, leading to increased data throughput for access points and requiring multiple messages for information acquisition, with users often unsure of transmission timing points for interworking information.
Innovation Solution
Implementing a method that utilizes an interworking information broker within the distribution system to efficiently acquire and transmit interworking information, reducing data processing throughput for access points and minimizing message count, while providing clear transmission timing points through beacon messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If access points process interworking information directly, then information acquisition is possible, but data processing throughput increases
Solution Approach 1:
The patent introduces an interworking information broker as an intermediary entity that centralizes the processing of interworking information. Instead of each access point processing information independently, the broker receives information requests from access points, acquires the necessary interworking information, and distributes it to the requesting access points. This mediator approach reduces the data processing burden on individual access points while ensuring comprehensive information acquisition.
2Loss of information
If multiple messages are used for information acquisition, then information can be obtained, but message transmission count increases
Solution Approach 1:
The interworking information broker performs preliminary actions by pre-acquiring and caching interworking information before access points need it. When an access point requests information, the broker can provide it from its cache rather than initiating new information acquisition sequences. This preliminary preparation reduces the number of messages required for information acquisition.
Solution Approach 2:
The broker consolidates multiple information acquisition operations into a single centralized process. Instead of access points individually querying for information (generating multiple messages), the broker handles information acquisition once and distributes it to multiple access points, significantly reducing the total message transmission count while maintaining information completeness.
3Adaptability or versatility
If access points handle interworking information, then communication is enabled, but device complexity increases
Solution Approach 1:
The patent separates the complex interworking information processing functions from the access points by introducing a dedicated broker entity. The broker handles the complexity of information acquisition, parsing, validation, and distribution, while access points only need to send simple requests and receive responses. This division of labor maintains communication capability while significantly reducing the complexity burden on access points.
Solution Approach 2:
The patent extracts the complex interworking information processing functionality from the access points and places it in a separate broker entity. By taking out these complex operations, the access points are left with simpler, more manageable tasks, while the broker assumes the complexity of handling diverse information formats, protocols, and acquisition mechanisms.

AI summary
A method for transmitting information of a network interworking with a wireless LAN (802.11, Wi-Fi) network or EMID (ESS MAC ID) provided from an EMID server to a wireless user equipment if the wireless user equipment accesses the wireless LAN network is disclosed. A wireless communication system which performs communication using a plurality of subcarriers includes at least one access point receiving messages from at least one wireless user equipment and communicating with another access point through a distribution system, and at least one interworking information broker receiving information request message of subscriber service provider network (SSPN) through interface with the at least one access point and acquiring response information corresponding to the information request message through interface with a network entity which includes information of the SSPN, the information request message of the SSPN being transmitted from the wireless user equipment to the at least one access point.
