UWB Advertising Poll Frames for Public and Private Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for various advertising methods and devices in an ultra-wideband (UWB) wireless network system, particularly in the context of discovery/initialization and setup processes involving secured/private and unsecured/public advertising messages.
Innovation Solution
The method involves generating and transmitting advertising poll frames with a frame identifier field, where the frame identifier field is set to different values based on whether a public address is used for session initialization, and receiving and performing session initialization processes based on information included in these frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different advertising poll frames are defined for public and private address sessions, then advertising versatility and session management capability are improved, but frame structure complexity and protocol design complexity increase
Solution Approach 1:
The advertising poll frame is segmented into multiple distinct types (public advertising poll frame and private advertising poll frame) based on the address type being used. Each frame type contains specific fields tailored to its purpose, allowing the system to handle both public and private sessions with appropriate frame structures rather than using a single complex frame for all purposes
Solution Approach 2:
The frame identifier field dynamically changes its meaning and required fields based on the type of advertising poll frame being transmitted. When a public address is used, the frame identifier indicates a public advertising poll frame with specific fields; when a non-public address is used, it indicates a private advertising poll frame with different field requirements, allowing flexible adaptation without fixed complexity
2Measurement precision
If frame identifier field is configured to distinguish between public and private advertising poll frames, then session initialization accuracy and address type identification are improved, but frame processing complexity and protocol overhead increase
Solution Approach 1:
The frame identifier field is pre-configured with specific values that immediately indicate the type of advertising poll frame (public or private) before processing begins. This preliminary identification mechanism allows receiving devices to quickly determine the frame type and initialize the appropriate session handling procedures without complex analysis, improving accuracy while keeping processing relatively simple
Solution Approach 2:
The frame identifier field uses different parameter values to represent different frame types. By changing the identifier parameter based on the address type (public or non-public), the system achieves precise session initialization accuracy through simple parameter comparison rather than complex frame processing

AI summary
Disclosed are a method and a device for various types of advertising in an ultra-wideband wireless network system. The method performed by a first device in an ultra-wideband (UWB) wireless network system according to an embodiment of the present disclosure may include the steps of: generating an advertising poll frame including a frame identifier field; and transmitting the advertising poll frame to one or more second devices. On the basis of multiple advertising poll frames being defined in relation to whether a public address is used for session initialization, the frame identifier field may be set to have different values with respect to the multiple advertising poll frames.
