Wireless A/V Connection Signaling Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in simplifying signaling for connection establishment between devices to transmit audio/video (A/V) data, leading to potential delays in displaying A/V data in wireless networks.
Innovation Solution
A method for controlling connection establishment in wireless networks that involves transmitting a connection request message with necessary information and capability details between devices, followed by a bandwidth reservation procedure to allocate channel resources, and includes specific message formats for connection requests and responses to streamline the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection control signaling is transmitted between devices to establish connection for A/V data transmission, then connection establishment is achieved, but signaling complexity increases and causes delay in displaying A/V data
Solution Approach 1:
The patent applies preliminary action by having devices pre-exchange capability information and perform bandwidth reservation procedures before actual A/V data transmission begins. The connection request message includes pre-configured capability information, and the coordinator performs bandwidth allocation in advance, so that when A/V data transmission starts, the connection is already established and resources are reserved, eliminating setup delays.
2Adaptability or versatility
If detailed capability information is included in connection request messages, then device compatibility is improved, but message complexity increases
Solution Approach 1:
The patent segments the connection establishment process into distinct phases: capability information exchange, connection request, bandwidth reservation, and data transmission. Each phase handles specific information types, so capability information is exchanged separately before connection requests are made. This segmentation allows detailed capability matching without overwhelming the connection request messages themselves.

AI summary
A method of controlling connection establishment to transmit or receive audio/video (A/V) data in a wireless network is provided. The method of controlling connection establishment to transmit or receive A/V data in a first device of a wireless network that includes a coordinator and at least one device includes transmitting connection request information required to request connection establishment with a second device and a connection request message which includes capability information of the first device to the second device and receiving a connection response message from the second device in response to the connection request message.
