Multimedia Session Capacity Checking via Aggregated Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and time-consuming process of capacity checking for multimedia sessions in cellular communication systems, particularly in large networks with thousands of radio base stations, where information sharing between organizational units is challenging, leading to inefficiencies in scheduling and planning of eMBMS sessions.
Innovation Solution
A method and system that utilize an aggregated capacity database and a resource capacity database to efficiently check and reserve capacity for multimedia sessions by receiving capacity requests, checking available bandwidth and radio resources, and sending responses, while allowing for detailed location-specific and QoS-class-based capacity management, and the option to reserve capacity without multiplexing with other sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If capacity checking is performed by checking each radio base station individually, then measurement precision is improved, but loss of time increases significantly
Solution Approach 1:
The patent segments the capacity checking process into two distinct phases: (1) an aggregated capacity check at the service area level that provides quick initial assessment, and (2) a detailed radio base station level check that provides precise capacity information. This segmentation allows the system to first filter out obviously insufficient service areas using aggregated data, then perform detailed checks only on promising candidates, thereby maintaining measurement precision while significantly reducing overall checking time.
Solution Approach 2:
The patent performs preliminary capacity assessment at the aggregated service area level before conducting detailed radio base station level checks. By pre-calculating and storing aggregated capacity information for service areas, the system can quickly eliminate service areas that cannot accommodate the requested capacity, thus avoiding time-consuming detailed checks on all radio base stations and significantly reducing total checking time while preserving accuracy for final decisions.
2Manufacturing precision
If detailed capacity checking is performed at radio base station level, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the capacity checking system into two independent but coordinated components: an aggregated capacity database at the service area level and a detailed radio base station capacity database. This segmentation allows each component to maintain appropriate detail level without overwhelming the entire system, reducing overall complexity while preserving the ability to perform precise capacity allocation when needed.
Solution Approach 2:
The patent introduces an intermediary aggregated capacity database that sits between the service area level and the radio base station level. This intermediary layer provides a simplified view of capacity for quick assessments and acts as a filter before detailed radio base station checks, thereby reducing the complexity of the overall system by avoiding the need for direct, continuous interaction between all service areas and all radio base stations.
3Adaptability or versatility
If information is shared between service operation department and RAN operation department, then adaptability is improved, but loss of time increases due to organizational barriers
Solution Approach 1:
The patent merges the capacity information from both the service operation department and the RAN operation department into a unified aggregated capacity database at the service area level. This consolidation allows both organizational units to access the same integrated information without requiring time-consuming back-and-forth communication, thereby improving adaptability while reducing information exchange time.
Solution Approach 2:
The patent introduces a centralized aggregated capacity database as an intermediary that both the service operation department and RAN operation department can access. This intermediary structure eliminates the need for direct, time-consuming communication between the two departments by providing a shared information repository that automatically reflects the current capacity status, thus improving information sharing efficiency.

AI summary
It is presented a method for checking capacity for a multimedia session. The method comprises the steps of: receiving a capacity request for a multimedia session, the capacity request comprising a desired bandwidth, a requested Quality of Service Class Identifier, QCI, a requested time window and a desired location in terms of at least one service area, each service area being served by a plurality of radio base stations; checking whether there is sufficient capacity in each service area for the desired bandwidth and desired QCI during the desired time window of the request by reading available 0 capacity in an aggregated capacity database, the aggregated capacity database comprising available bandwidth capacity on a service area level and by reading available radio capacity on a radio resource level in a resource capacity database; and sending a response based on whether there is sufficient capacity or not.
