Terminal Device Session Initiation Information Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where both conventional telephone numbers and SIP protocol addresses are used, users face the challenge of maintaining up-to-date contact information, which is time-consuming and often neglected, making it difficult to establish connections efficiently.
Innovation Solution
Terminal devices exchange session initiation information during active communications connections, allowing for automatic updates and storage for future sessions, independent of user intervention, using a software application that facilitates the exchange of address information between devices via the SIP protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually update contact information for both conventional telephone numbers and SIP addresses, then contact information can be kept up-to-date, but this process is time-consuming and laborious
Solution Approach 1:
The terminal device automatically updates its own contact information by extracting and storing session initiation information from incoming SIP calls without requiring user intervention. The device serves itself by monitoring incoming calls, extracting contact details from SIP protocol data, and updating the address book automatically.
Solution Approach 2:
The terminal device performs preliminary actions by pre-extracting and storing contact information from incoming SIP calls before the user needs to make a new connection. This ensures that when the user initiates a call, the contact information is already updated and ready for use.
2Measurement precision
If users manually maintain contact information across multiple communication protocols, then connection accuracy can be maintained, but the complexity of the operation increases
Solution Approach 1:
The terminal device automatically extracts contact information from SIP protocol data structures and updates its address book without requiring user intervention. The device handles the complexity of parsing SIP messages, extracting relevant fields, and storing them in the appropriate format.
Solution Approach 2:
The terminal device acts as an intermediary between the SIP protocol and the user's contact management system. It translates SIP protocol data into a usable format for the address book, handling the complexity of protocol parsing and data transformation automatically.
3Reliability
If users frequently update contact information to ensure connectivity, then connection reliability improves, but the time required for session initiation increases
Solution Approach 1:
The terminal device performs preliminary updates by extracting and storing contact information from incoming SIP calls in real-time. This ensures that contact information is updated continuously in the background, so when the user needs to initiate a call, the information is already current without requiring additional update time.
Solution Approach 2:
The automatic update process operates continuously in the background during incoming calls, constantly refreshing contact information without interrupting the user's workflow. This continuous background operation ensures information is always current while minimizing impact on user time.
