Dynamic RAN Priority Allocation for First Responder Personal UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio access networks (RANs) face challenges in providing prioritized wireless service to first responders' personal UEs outside their dedicated communication equipment, as these devices are not registered with the responder agency and thus do not receive priority access during emergencies.
Innovation Solution
An Alert and Priority System (APS) identifies relevant personal UEs associated with first responders based on event occurrences, modifying RAN parameters to provide dynamic priority access and notifications, ensuring they receive enhanced service without permanent priority allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated RF resources are allocated to first responder agencies, then priority access is ensured for agency-provided devices, but personal UEs of first responders do not receive priority service during emergencies
Solution Approach 1:
The system enables RF resources dedicated to first responder agencies to serve multiple functions: both agency-provided devices and personal UEs of first responders can access priority service through the same dedicated resources. The APS identifies personal UEs associated with first responders and grants them access to the dedicated RF resources, making the priority service system universal across different device types owned or operated by first responders.
Solution Approach 2:
The Alert and Priority System (APS) acts as an intermediary between the dedicated RF resources and personal UEs. The APS receives alerts, identifies associated personal UEs, and facilitates their access to priority RF resources without requiring permanent configuration changes or direct registration of personal devices with the agency.
2Reliability
If personal UEs are permanently registered for priority access, then reliable communication is ensured during emergencies, but RF resources are permanently allocated reducing availability for other users
Solution Approach 1:
The system dynamically allocates RF resources based on real-time emergency conditions rather than permanent static allocation. When the APS detects an emergency alert, it temporarily grants priority access to associated personal UEs. When no emergency is detected, the dedicated RF resources remain allocated to general pool availability. This dynamic approach ensures communication reliability during emergencies while maximizing RF resource availability during normal operations.
Solution Approach 2:
The system changes the priority parameter of personal UEs dynamically based on emergency alert status. During emergencies, the priority parameter is elevated to enable access to dedicated RF resources. During normal operations, the priority parameter is reduced or removed, allowing resources to be reallocated. This parameter change mechanism enables flexible resource management without permanent commitments.
3Productivity
If RF resources are dynamically reallocated based on events, then resource utilization is optimized, but system complexity increases
Solution Approach 1:
The system performs preliminary identification and association of personal UEs with first responders before emergencies occur. The APS maintains pre-configured associations between first responders and their personal UEs, and pre-identifies which RF resources are dedicated to first responder agencies. When an emergency alert is received, the system only needs to execute the pre-planned allocation logic, significantly reducing the computational complexity during real-time dynamic reallocation.

AI summary
A system described herein may provide a technique for identifying User Equipment (“UEs”) associated with relevant users, such as “personal” UEs associated with first responders, based on the occurrence of an event, notifying the UEs of the event, and modifying radio access network (“RAN”) parameters such that the identified UEs are provided with priority access. Further, such modifications may be temporary (e.g., reverted after the event has occurred). In this manner, personal UEs associated with relevant users may be dynamically provided priority access in situations where such access may be beneficial, without needing to permanently provide the priority access to such UEs.
