Service Device Resource Allocation for Real-Time Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia content providing services face limitations in efficiently managing simultaneous user access due to radio resource constraints, leading to low access success rates and long download times, especially when real-time and reserved content requests are made concurrently, and struggle to identify and serve popular reproduction intervals within multimedia content.
Innovation Solution
A service device and method that allocates transmission resources by prioritizing real-time content requests and then allocating remaining resources to reserved content requests, selecting UEs with smaller content capacities or those that re-request content to optimize resource utilization, ensuring a guaranteed transmission rate for both types of requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If transmission resources are allocated to multiple UEs simultaneously requesting content, then the number of served users increases, but the transmission rate per user decreases and download time increases
Solution Approach 1:
The patent segments the content delivery process into two distinct phases: real-time delivery phase and reserved delivery phase. This segmentation allows the system to handle different user requests through different resource allocation strategies, preventing resource contention between simultaneous requests while ensuring both real-time and reserved users are served effectively
Solution Approach 2:
The patent implements preliminary resource allocation for real-time users before handling reserved users. By first allocating resources to real-time users who require immediate service, the system ensures their transmission rate requirements are met, then allocates remaining resources to reserved users, thereby resolving the contradiction between serving multiple users and maintaining transmission speed
2Reliability
If all reserved content requests are served simultaneously, then user satisfaction increases, but resource capacity is exceeded and service quality degrades
Solution Approach 1:
The patent changes the parameter of resource allocation by introducing dynamic selection criteria for reserved users. Instead of serving all reserved users equally, the system selects a subset of reserved users based on their content capacity requirements and service priorities, thereby maintaining service quality while managing total content capacity within available resources
Solution Approach 2:
The patent applies partial action by serving only a portion of the reserved content requests in each time slot. Rather than attempting to serve all reserved users simultaneously (which would exceed resource capacity), the system selectively serves qualified reserved users, ensuring service quality is maintained while progressively fulfilling multiple user requests over time
3Ease of operation
If conventional content classification by popularity is implemented, then users can easily find popular contents, but users cannot efficiently access specific popular intervals within long multimedia contents
Solution Approach 1:
The patent segments multimedia content into multiple time intervals and identifies popular intervals within each content piece. Instead of treating content as a single unit, the system divides it into segments and determines which segments are most popular, allowing users to directly access specific popular intervals without watching or downloading entire long contents, thereby reducing time loss while maintaining ease of operation
Solution Approach 2:
The patent adds a temporal dimension to content classification by analyzing and identifying popular time intervals within contents. This dimensional approach transforms the conventional content-level popularity metric into a more granular time-interval-level metric, enabling users to quickly locate and access specific popular segments without traversing the entire content duration

AI summary
A content providing service system includes a plurality of UEs configured to request and receive real time contents required to be received in real time or reserved contents reserved in advance from a service device and the service device configured to, when the real time contents or the reserved contents are requested from each of the plurality of UEs at a particular time, first allocate transmission resources to the UEs which request the real time contents and allocate the remaining transmission resources except for the first allocated transmission resources to at least some of the UEs which request the reserved contents.
