Priority Service Bearer Creation for Network-Initiated IMS Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not support priority services initiated from the network to a target user, limiting the provision of priority services to users who require them.
Innovation Solution
Methods and apparatuses are developed to determine and create priority service bearers for network-initiated services, ensuring that priority services are provided by updating or allocating bearers to target user equipment, and initiating network access procedures to ensure priority treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system only supports user-initiated priority services, then the complexity of the system is reduced, but the adaptability and versatility of the service are limited
Solution Approach 1:
The system is enhanced to support both user-initiated and network-initiated priority services through a unified bearer creation mechanism. The network device can now initiate priority services by sending service requests to the IP multimedia subsystem, which then triggers bearer creation and routing procedures similar to user-initiated services, making the system more versatile without requiring fundamentally different processing paths
Solution Approach 2:
The traditional model where only users initiate services is inverted to allow network devices to initiate priority services as well. This is achieved by enabling network devices to send service requests through the IP multimedia subsystem, which then processes these requests similarly to user requests, effectively reversing the traditional initiation direction while maintaining system consistency
2Reliability
If a priority service bearer is created for network-initiated services, then the reliability of priority service delivery is improved, but the device complexity increases due to additional bearer management functions
Solution Approach 1:
The IP multimedia subsystem acts as an intermediary between network devices and the bearer management system. When a network device initiates a priority service, it sends a service request to the IP multimedia subsystem, which then handles the bearer creation and management procedures, shielding the network device from complex bearer management while ensuring reliable priority service delivery through dedicated bearers
Solution Approach 2:
The system employs self-service mechanisms where the IP multimedia subsystem automatically manages bearer creation, modification, and teardown based on service requests. When a network-initiated priority service is requested, the subsystem autonomously triggers the appropriate bearer management procedures without requiring manual intervention or complex external coordination, improving reliability while managing complexity through automation
