Centralized Terminal Capability Management for Wireless Signaling Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for session initiation and updating in wireless networks result in wastage of radio resources due to frequent transmission of terminal capability information, especially when capabilities change during multiple services, leading to high communication costs.
Innovation Solution
A centralized Terminal Configuration Management (TCM) server manages capability information and versioning, allowing efficient transmission of changed capabilities only when necessary, reducing unnecessary radio resource usage and communication costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal capability information is transmitted frequently to reflect capability changes, then service adaptability is improved, but radio resource wastage increases
Solution Approach 1:
The system performs preliminary registration of terminal capability information with the application server before services are actually needed. When capabilities change, the terminal proactively notifies the server in advance, so that when services are requested, the server already has updated capability information, eliminating the need for frequent capability inquiry transmissions.
Solution Approach 2:
The system establishes a feedback mechanism where the terminal notifies the application server of capability changes proactively. This feedback loop ensures the server maintains current capability information without requiring continuous polling or frequent transmission requests, thus reducing radio resource usage while maintaining service adaptability.
2Reliability
If capability information is re-transmitted for each service when capabilities change, then service accuracy is improved, but communication cost increases
Solution Approach 1:
The application server is designed to handle multiple services while maintaining a single updated capability record for each terminal. When capability information is updated, it becomes universally applicable to all services, eliminating the need to re-transmit capability information for each individual service request.
Solution Approach 2:
The system merges the capability management function into the application server, combining capability storage, update notification handling, and service provisioning into a single integrated system. This consolidation ensures that capability information is maintained centrally and automatically applied across all services without redundant transmissions.
3Loss of information
If full capability information is transmitted whenever any capability changes, then information completeness is improved, but signaling overhead increases
Solution Approach 1:
The system segments capability information into distinct capability elements that can be independently tracked and updated. When a capability changes, only the specific changed capability element is transmitted in the notification, rather than re-transmitting the entire capability information set, thus maintaining information completeness while reducing signaling overhead.
Solution Approach 2:
The system utilizes parameter change notifications where the terminal identifies and transmits only the specific capability parameters that have changed. This selective transmission approach ensures the server receives complete and accurate capability information about changed parameters without the overhead of transmitting unchanged parameters repeatedly.

AI summary
Management of capability information is disclosed. A server in a network acquires information about capability of a user equipment (or terminal) and manages the information in a centralized manner, to reduce signaling through a radio interface between user equipments to thus reduce a waste of radio resources.
