Innovation Solution
A method for establishing a docking protocol between wireless devices involves transmitting probe and service discovery frames, establishing an ASP session, and selectively configuring the protocol based on device capabilities and types, enabling the use of peripheral functions over a Wi-Fi network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wi-Fi Direct technology is used for direct communication between devices, then device connectivity is improved, but the ability to utilize peripheral functions is limited due to lack of standardized docking protocol
Solution Approach 1:
The docking protocol establishment is segmented into distinct phases: probe request/response for device discovery, service discovery request/response for capability identification, and ASP session establishment for functional configuration. This segmentation allows each phase to be handled independently, enabling peripheral function utilization without requiring a complex monolithic setup procedure.
Solution Approach 2:
The probe request and service discovery frames are exchanged beforehand to identify device capabilities and available peripheral functions before actual docking operations commence. This preliminary action allows the system to pre-configure the ASP session with appropriate parameters, eliminating the need for complex real-time configuration during peripheral function utilization.
2Adaptability or versatility
If a standardized docking protocol is established through probe and service discovery frames, then device interoperability is improved, but communication overhead is increased
Solution Approach 1:
The ASP session establishment protocol serves multiple functions simultaneously: it performs device capability negotiation, configures peripheral function access parameters, and sets up communication channels. This multi-functionality reduces the need for separate standardized protocols for each function, thereby improving device interoperability without proportionally increasing communication overhead.
Solution Approach 2:
The probe request frame and service discovery frame are combined into a sequential exchange process where capability identification and session configuration are merged into a single standardized docking protocol flow. This merging reduces the total number of separate communication exchanges needed, balancing interoperability standards with communication efficiency.

AI summary
Disclosed are a method for constructing a docking protocol for using a docking service in a direct communication system, and an apparatus therefor. To this end, a method by which a first wireless device constructs a docking protocol with a second wireless device comprises: a step for searching for a probe; a step for searching for a service; a step for enabling the first wireless device to construct an application service platform (ASP) session with the second wireless device; and a step for enabling the first wireless device to construct a docking protocol with the second wireless device. At this point, the step for constructing the ASP session can be selectively performed according to the capability or the device type of the first wireless device or the second wireless device.
