Mobile Network Scheduling for Privileged User Access Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile network technologies do not effectively prioritize packet switched data services for privileged users during emergency situations, leading to potential congestion and failure in resource allocation for critical services like video calls and multimedia information.
Innovation Solution
The method combines Allocation/Retention Priority (ARP) information with pre-emption strategies, using both service and user-specific Quality of Service (QoS) attributes to prioritize radio resource allocation, employing threshold-based procedures for switching between soft and hard pre-emption, and integrating CS and PS service parameters for admission control, scheduling, and interference reduction.

Engineering Contradiction Analysis
1Reliability
If eMLPP pre-emption is applied for CS services, then privileged users gain preferential access rights, but packet switched data services lack prioritization mechanisms
Solution Approach 1:
The patent extends the eMLPP pre-emption mechanism originally designed for circuit-switched services to packet-switched data services. The core pre-emption logic is made universal across different service domains, allowing privileged users to gain prioritization in both CS and PS domains through a unified approach.
Solution Approach 2:
The patent introduces QoS parameters including ARP (Allocation/Retention Priority) to differentiate and prioritize packet-switched services. By changing the parameter set from traditional CS-domain parameters to PS-domain QoS parameters, the system enables prioritization mechanisms appropriate for data services while maintaining the privileged access model.
2Productivity
If network resources are allocated to ordinary users during congestion, then network utilization is maximized, but privileged users cannot establish calls
Solution Approach 1:
The patent implements pre-emption mechanisms that allow privileged users to preemptively take over network resources when needed. The system prepares for potential privileged user needs by maintaining the capability to reallocate resources dynamically, preventing resource starvation for critical services even when resources are currently allocated to ordinary users.
Solution Approach 2:
The patent creates a dynamic resource allocation system where resource assignment is not fixed but can change based on user priority and network conditions. The scheduler continuously adjusts resource distribution by evaluating QoS parameters and pre-emption rules, allowing the system to adapt between maximizing utilization and ensuring privileged access based on real-time needs.
3Device complexity
If standard QoS parameters are used for resource distribution, then resource allocation is simplified, but privileged treatment for specific user groups cannot be implemented
Solution Approach 1:
The patent merges standard QoS parameters with eMLPP priority levels into a unified scheduling framework. By combining these two parameter sets, the system maintains the simplicity of standard QoS mechanisms while incorporating the privileged access rights of eMLPP, allowing both ordinary QoS differentiation and special privileged treatment to coexist in the resource allocation process.

AI summary
The present invention relates to a mobile communication system. In particular, to the field of handling preferred access rights within the packet switched part of a mobile network. The present invention teaches using both, user specific priority classes standardised for packet switched services as well as priority classes standardised for circuit switched services in the packet switched domain. Further, the present invention relates to a preferred scheduling for prioritised users in the packet switched domain based on priority classes defined for packet switched and circuit switched services. Furthermore, the invention relates to a procedure of controlling preferred access rights and scheduling priority in a communication system serving prioritised and non-prioritised users.
