Solution Overview

Problem

Current 3G and 4G wireless communication networks face challenges in dynamically updating user equipment (UE) capability information, leading to potential resource conflicts and interruptions in multiple connections due to static reporting schemes.

Innovation Solution

Implementing a method and apparatus that dynamically determine and signal instantaneous UE capability information (IUCI) and instantaneous network capability information (INCI) to mitigate resource conflicts by continuously updating capability information without disconnecting or reconnecting connections, using processors and software to manage resource allocation and signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static capability information reporting schemes are used in 3G/4G networks, then device capability information can be reported to the network, but resource conflicts and connection interruptions occur due to inability to dynamically update capability information

Engineering Contradiction:
Improvecapability information updating capabilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent transforms the static capability information reporting mechanism into a dynamic one by enabling real-time updates of UE capability information and network capability information. The system allows capability information to be updated during active connections without requiring connection release and re-establishment, thereby resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where the UE continuously reports its capability information to the network, and the network responds with network capability information. This bidirectional feedback enables both parties to adapt to changing conditions while maintaining connection stability, resolving the technical contradiction.

Inventive Principle:
Principle #23Feedback

2Productivity

If capability information is updated dynamically during active connections, then resource conflicts can be mitigated, but additional signaling overhead and processing complexity are introduced

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidsignaling and processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments capability information into different types (UE capability information and network capability information) and updates them independently through targeted signaling messages. This segmentation allows efficient resource allocation without requiring complete capability information exchanges, reducing overall signaling complexity while improving productivity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple connections are maintained simultaneously, then service continuity is improved, but resource conflicts arise due to static capability information not reflecting current resource availability

Engineering Contradiction:
Improveservice continuityVSAvoidresource allocation flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs continuous feedback mechanisms where capability information is exchanged and updated across multiple connections. This enables the system to maintain service continuity while adapting resource allocation to current conditions, resolving the contradiction between reliability and adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent enables dynamic capability information updates across multiple simultaneous connections, allowing the system to adapt resource allocation flexibly while maintaining service continuity. This dynamic approach resolves the contradiction between maintaining multiple connections and avoiding resource conflicts.

Inventive Principle:
Principle #15Dynamics

AI summary

Methods and apparatuses of wireless communications are provided to dynamically determine capability information such that potential configuration and/or resource conflicts may be mitigated among multiple connections while one or more of on-going connections are not interrupted. A user equipment (UE) establishes one or more connections with a network. The UE allocates, in a first resource allocation, one or more resources of the UE to the one or more connections. The UE dynamically determines an instantaneous UE capability information (IUCI) of the UE in response to a change from the first resource allocation to a second resource allocation, the IUCI indicative of the capability of the UE during a predetermined time period. The UE transmits the IUCI to the network to mitigate potential resource allocation conflict among the one or more connections while maintaining at least one of the connections.
