Terminal Interoperation via Functional Characteristic Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication networks face issues when a calling terminal with higher capabilities connects to a called terminal with lower capabilities, leading to potential overload, session failure, and degraded user experience due to differences in access network capabilities.
Innovation Solution
Implementing a system that alters communication sessions by determining and adjusting the data characteristics to match the least capable access network involved, allowing seamless communication by altering data formats, resolutions, or protocols to ensure compatibility and prevent overload.

Engineering Contradiction Analysis
1Productivity
If a calling terminal with higher capabilities initiates a session with a called terminal with lower capabilities, then the calling terminal can provide high-quality services, but the called terminal may become overloaded or the session may fail
Solution Approach 1:
The calling terminal retrieves functional characteristics of the called terminal from a presence server before initiating the session. This preliminary action allows the calling terminal to assess the called terminal's capabilities in advance and adjust session parameters accordingly, preventing overload and session failure while maintaining high-quality service where possible
Solution Approach 2:
The system alters session parameters such as data format, resolution, or protocol based on the functional characteristics of the called terminal. By dynamically changing these parameters to match the called terminal's capabilities, the system ensures session success while optimizing service quality within the constraints of the lower-capability terminal
2Productivity
If the calling terminal uses high-performance data formats and protocols, then service quality is improved, but compatibility with lower-performance access networks deteriorates
Solution Approach 1:
The system dynamically changes data format, resolution, and protocol parameters based on the functional characteristics of the called terminal and its access network. This allows high-performance formats to be used when compatible, while automatically falling back to lower-performance formats when necessary, thus maintaining both service quality and network compatibility
Solution Approach 2:
The session configuration is made dynamic rather than static. The system continuously adapts session parameters based on real-time assessment of the called terminal's functional characteristics, allowing the session to operate at high performance when possible and gracefully degrade when network compatibility requirements demand it

AI summary
Example techniques described herein can permit interoperation between network terminals that have different performance characteristics, or that are connected via access networks having different performance characteristics. A calling terminal (or a core network device) can retrieve an indication of functional characteristics associated with a called terminal. The indication can be included in presence information associated with the called terminal. The calling terminal can determine a altered functional specification based at least in part on the functional characteristics and a functional specification of a session. The functional characteristics can satisfy the altered functional specification. The calling terminal can initiate a altered session with the called terminal via the network based at least in part on the altered functional specification. A terminal can detect network service provided by an access network and transmit presence information to a presence-information server. The presence information can indicate a type of the access network.
