Joint Data Flow Admission Control for Synchronized Wireless Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack effective mechanisms for coordinating and enforcing admission control for groups of data flows and user equipment, leading to out-of-sync playback and resource wastage in wireless communication networks.
Innovation Solution
A method and apparatus for a radio access network entity to determine resource availability for joint handling of data flows and user equipment, with mechanisms for resource reservation, timer-based management, and release of unconfigured resources, and signaling between network functions for coordinated resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are reserved for all data flows and user equipment in advance, then resource availability for joint handling is improved, but resource wastage increases when resources are not fully utilized
Solution Approach 1:
The patent applies preliminary action by reserving resources in advance for a group of data flows and user equipment before actual transmission begins. The radio access network entity determines resource availability and reserves resources for joint handling of multiple data flows, ensuring that resources are ready when needed while maintaining the ability to release unused resources later.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting resource allocation based on actual transmission needs. Resources are reserved initially with certain parameters (quantity, time duration), and then these parameters are modified through timer expiration and resource release mechanisms when the actual usage differs from the initial reservation, optimizing both availability and efficiency.
2Stability of the object's composition
If resources are allocated for joint handling of multiple data flows, then synchronized delivery is improved, but system complexity increases
Solution Approach 1:
The patent applies merging by combining multiple data flows and user equipment into a single joint handling group. The radio access network entity treats the group of data flows as a unified resource allocation unit, determining resource availability for the entire group simultaneously and making coordinated resource reservations that ensure synchronized delivery while simplifying management compared to individual flow handling.
Solution Approach 2:
The patent implements universality by creating a multi-functional resource allocation mechanism that can handle multiple data flows and user equipment simultaneously through a single resource reservation process. The same resource reservation and timer management procedures apply whether handling one data flow or multiple data flows jointly, reducing the need for separate specialized mechanisms.
3Productivity
If timer-based resource management is implemented, then resource release efficiency is improved, but control overhead increases
Solution Approach 1:
The patent applies periodic action through timer-based resource management where resources are reserved for a predetermined time period and automatically released when the timer expires. This periodic mechanism ensures that reserved resources are released systematically without requiring continuous manual intervention, improving resource release efficiency while maintaining manageable control overhead through automated timer management.
Solution Approach 2:
The patent implements self-service by enabling resources to be automatically released through timer expiration without requiring explicit release commands from the network function. The radio access network entity autonomously manages resource release based on the timer status, reducing control overhead while maintaining efficient resource turnover and availability for subsequent allocations.
