Temporary Bearer Priority Matching for Congested MPS Calls

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless networks fail to provide priority access for non-high priority access (non-HPA) subscribers during network congestion, leading to communication failures for critical services like multimedia priority services (MPS) when HPA subscribers communicate with non-HPA subscribers, especially in RRC-idle mode, and ongoing sessions are vulnerable to preemption.

Innovation Solution

Non-HPA subscribers in RRC-idle mode receive a priority paging message, temporarily elevating their priority status to increase network accessibility, and respond with an RRC Connection Request designating high priority, while in RRC-connected mode, the core network triggers a bearer update process to elevate priority for non-HPA subscribers, ensuring end-to-end priority treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless networks provide priority access for HPA subscribers during network congestion, then critical services for national security and public safety are ensured, but non-HPA subscribers experience access denial and communication failures

Engineering Contradiction:

Improvereliability of critical servicesVSAvoidaccessibility for non-HPA subscribers

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements dynamic priority assignment where non-HPA subscribers temporarily receive high priority status when engaged in MPS sessions with HPA subscribers. The network device dynamically adjusts the priority level of non-HPA subscribers based on session context, allowing them to access the network during congestion while maintaining reliability for critical services.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the priority parameter of non-HPA subscribers from low to high temporarily during MPS sessions. The network device modifies the access priority parameter dynamically based on session type and participant status, enabling non-HPA subscribers to overcome access denial during network congestion while HPA subscribers maintain their critical service reliability.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If non-HPA subscribers are denied access during network congestion to ensure HPA subscriber priority, then network resource allocation is optimized for critical services, but MPS sessions between HPA and non-HPA subscribers fail to establish

Engineering Contradiction:

Improvenetwork resource allocation efficiencyVSAvoidestablishment of MPS sessions

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic priority adjustment where non-HPA subscribers involved in MPS sessions with HPA subscribers are temporarily granted high priority status. This dynamic reassignment allows MPS sessions to establish successfully during congestion while maintaining overall network resource allocation efficiency for critical services.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The network device acts as an intermediary that identifies MPS sessions involving non-HPA subscribers and temporarily elevates their priority status. This intermediary function allows the system to maintain resource allocation efficiency while enabling critical MPS communications that would otherwise fail during congestion.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Quantity of substance

If non-HPA subscribers maintain low priority status during network congestion, then network capacity is preserved for HPA subscribers, but ongoing MPS sessions are vulnerable to preemption

Engineering Contradiction:

Improvenetwork capacity availabilityVSAvoidsession continuity

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent implements dynamic priority maintenance where non-HPA subscribers engaged in MPS sessions with HPA subscribers receive temporary high priority status. This dynamic adjustment protects ongoing MPS sessions from preemption while preserving network capacity for other HPA subscriber communications, ensuring both session continuity and capacity availability.

Inventive Principle:

Principle #15Dynamics

AI summary

Systems and methods establish and maintain end-to-end priority of wireless multimedia priority service (MPS) sessions terminating to subscribers without high priority access. A network device a wireless core network receives a request to establish a bearer for an elevated priority call. The elevated priority call originates from a first user equipment (UE) device in a Radio Resource Control (RRC) connected mode having an elevated priority status and terminates at a second UE device in a RRC connected mode having a non-elevated priority status. The network device determines modification of a terminating bearer for the second UE device is necessary to preclude preemption during periods of network congestion and identifies a high priority parameter of an originating bearer for the first UE device. The network device initiates establishment of the terminating bearer to match the high priority parameter of the originating bearer.
