Video Call Session Setup with Custom Message Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a video call on mobile terminals is time-consuming due to complex message processing operations, taking longer compared to voice calls.
Innovation Solution
A method and terminal configuration that transmit custom messages to establish a video call, allowing for session replacement with a fast session upon receiving a second custom message during the call, utilizing a communication unit to set up and maintain a high-speed video call connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex message processing operations are used to establish a video call, then the video call can be set up with proper configuration, but the establishment time becomes prolonged
Solution Approach 1:
The patent applies preliminary action by pre-configuring custom messages and processing parameters before the actual video call establishment. The terminal prepares custom messages containing video call parameters in advance, so when a video call is initiated, the complex processing operations can be executed more quickly without delaying the overall setup time. This allows the system to maintain reliable configuration while reducing the perceived establishment time.
2Reliability
If conventional message processing operations are used, then proper video call configuration is achieved, but data transmission speed remains slow
Solution Approach 1:
The patent applies parameter changes by modifying the message processing parameters to optimize for speed. The terminal changes processing parameters such as message validation levels, error checking thresholds, and data transmission rates. By adjusting these parameters dynamically during the call establishment and execution phases, the system maintains configuration accuracy while significantly improving data transmission speed compared to conventional fixed-parameter processing.

AI summary
A terminal includes a communication unit to transmit a first custom message to a called terminal according to a video call request, and to receive a connect message from the called terminal; and a connection unit to setup a session for the video call with the called terminal, and if a second custom message is received from the called terminal, to replace the session with a fast session for a high-speed video call. A method for establishing the fast session of a video call includes transmitting the first custom message to the called terminal, receiving a connect message, setting up a session for the video call with the called terminal, and replacing the session with a fast session for a high-speed video call if a second custom message is received from the called terminal.
