UE Capability Modification for Simultaneous Service Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a mechanism to effectively manage and indicate the simultaneous support of dedicated services and Multimedia Broadcast/Multicast Services (MBMS) beyond minimum benchmarks, leading to limitations in service levels and conflict resolution, where UE capabilities are not accurately represented to the network.
Innovation Solution
A method and system that allow user equipment (UE) to modify its represented capabilities by sending UE CAPABILITY INFORMATION messages to the network, enabling the allocation of processing resources to support both dedicated services and MBMS, with the ability to adjust data rates dynamically to accommodate available resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE indicates its full capability to support dedicated service, then the dedicated service quality is improved, but the UE cannot simultaneously support MBMS service
Solution Approach 1:
The patent applies dynamics by making the UE capability indication flexible and changeable. The UE dynamically modifies its indicated capability from the full capability to a modified capability when MBMS service is detected, and can revert back when MBMS service ends. This dynamic adjustment allows the UE to adapt between different service scenarios, resolving the contradiction between maintaining dedicated service quality and supporting multiple services simultaneously.
Solution Approach 2:
The patent applies parameter changes by modifying the capability parameter that the UE reports to the network. Instead of reporting a fixed capability, the UE changes the capability parameter based on the detected MBMS service conditions. The UE determines a modified capability that reflects the reduced resources available when MBMS is active, and reports this modified capability to the network, enabling the network to reconfigure the dedicated service accordingly.
2Adaptability or versatility
If the UE allocates resources to support MBMS service, then the service diversity is improved, but the dedicated service data rate decreases
Solution Approach 1:
The patent applies partial action by having the UE allocate only a portion of its total capability to the dedicated service when MBMS service is active. Instead of allocating full capability to dedicated service, the UE determines a modified capability that represents the partial allocation remaining after reserving resources for MBMS. This partial allocation allows the UE to support both services simultaneously, with the dedicated service operating at a reduced but still functional data rate.
3Adaptability or versatility
If the network reconfigures dedicated service based on modified capability, then the simultaneous service support is improved, but the system complexity increases
Solution Approach 1:
The patent applies self-service by having the UE autonomously determine and report its modified capability without requiring complex network-side resource allocation algorithms. The UE independently assesses its resource availability when MBMS service is detected, calculates the modified capability, and reports it to the network. This self-service approach simplifies the overall system complexity by shifting the capability determination function to the UE, while still enabling the network to reconfigure the dedicated service based on the reported modified capability.

AI summary
Methods and apparatus for modifying wireless devices represented or available capabilities and for allocating a portion of the UE's actual capabilities for simultaneously supporting a second service is disclosed. A modified capability is determined and offered to maintain the dedicated service while supporting a second service. The modified capability is disclosed to a system in anticipation of a reconfiguration of the dedicated service according to the modified capability. A device is configured to determine a modified capability to maintain a dedicated service while supporting a second service; and to disclose to a system the modified capability as the available capability for reconfiguring the dedicated service.
