Persona Significance in LTE Uplink Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication systems, particularly in LTE networks, fail to effectively manage multiple-persona scenarios where different personas require distinct priority settings for applications, leading to conflicts between persona significance and existing Quality-of-Service frameworks, resulting in inefficient use of resources and suboptimal service delivery.
Innovation Solution
The introduction of persona significance information into the uplink scheduler of user equipment (UE) and evolved Node B, allowing for prioritization of data bearers based on persona significance, aligning Allocation and Retention Priority (ARP) with persona importance, and propagating this significance through the LTE network nodes to ensure optimal resource allocation and service precedence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple personas are supported in a cellular device, then the device can access multiple networks simultaneously for different applications, but resource allocation conflicts arise between personas with different priority requirements
Solution Approach 1:
The patent segments resource allocation by introducing persona-specific priority levels and separate Quality-of-Service (QoS) parameter sets for each persona. The uplink scheduler is divided into persona-aware components that independently manage resources for each persona based on their respective priority requirements, allowing simultaneous multi-network access without allocation conflicts.
Solution Approach 2:
The patent adds a persona dimension to the traditional QoS framework by introducing persona significance information as a new layer of priority classification. This dimensional extension allows the system to differentiate and manage multiple personas with distinct priority requirements, transforming the resource allocation problem from a flat structure to a multi-dimensional one that accommodates persona-specific needs.
2Reliability
If existing Quality-of-Service frameworks are used without modification, then the system maintains standard LTE operation, but it cannot effectively prioritize applications based on persona significance
Solution Approach 1:
The patent modifies the existing QoS framework by introducing new parameters including persona significance information, persona-specific priority levels, and extended QoS parameter sets. These parameter changes enable the system to differentiate between personas and applications, allowing effective prioritization while maintaining backward compatibility with standard LTE operations through the extended parameter structure.
3Productivity
If persona significance information is propagated through all LTE network nodes, then optimal resource allocation is achieved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent introduces persona significance information as an intermediary element that mediates between the UE's multiple personas and the LTE network's resource allocation mechanisms. This intermediary information is propagated through network nodes (eNodeB, core network) to enable coordinated resource management, optimizing allocation efficiency while maintaining a structured approach to handling the added complexity through standardized information exchange.

AI summary
A multiple-persona system and method is described, wherein a UE (user equipment) is able to connect to two different networks simultaneously. In a multiple-persona system, one of the personas may have a higher significance than the other persona. For example, a connection to a work network may be prioritized over connection to a home network. In such a situation, it may be desirable to have applications running on the work network have priority over applications running on the home network. Such a method and system may operate independently of the eNodeB or have the eNodeB actively controlling the priority among the personas. The scheduler in either the eNodeB or the UE may contain anew input for the significance of the persona. The significance of the persona is taken into account when sending data to and from the UE.
