Multimedia Services Grouping for Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP MBMS specification lacks a mechanism to identify relevant groups of users based on service and content, leading to sub-optimal use of network resources and potential network congestion due to excessive demand for multimedia services.
Innovation Solution
A method and system for creating multicast groups by determining the type and number of multimedia services subscribed by each UE, grouping UEs based on similarity in services and service numbers, and optimizing resource utilization by forming multicast or broadcast groups accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the same content is transmitted to a large number of subscribers using traditional unicast methods, then each subscriber can receive the content, but network resources are excessively consumed and network capacity is exceeded
Solution Approach 1:
The patent merges multiple unicast transmissions into a single multicast transmission by grouping subscribers with similar service subscriptions into multicast groups. The eNB transmits one copy of the content to the entire group simultaneously, reducing network resource consumption from linear scaling (N subscribers requiring N transmissions) to constant scaling (N subscribers requiring 1 transmission), thereby resolving the contradiction between serving more subscribers and conserving network resources.
Solution Approach 2:
The patent creates universal multicast groups that can serve multiple subscribers with different but overlapping service subscriptions. A single multicast transmission can serve multiple UEs simultaneously, making the transmission mechanism universally applicable to various subscription combinations. This multi-functionality allows the system to efficiently serve a diverse range of subscribers without proportionally increasing network resource consumption.
2Productivity
If multicast groups are formed without considering service similarity, then group formation is simple, but radio resources are not used effectively and service quality deteriorates
Solution Approach 1:
The patent performs preliminary actions by having UEs report their service subscriptions to the eNB before multicast group formation. The eNB pre-processes this subscription information to identify UEs with similar service profiles, then forms multicast groups based on this pre-analyzed data. This preliminary classification simplifies the actual group formation process while ensuring optimal radio resource utilization, as groups are formed based on service similarity rather than arbitrary criteria.
Solution Approach 2:
The patent changes the grouping parameter from simple connection status to service subscription similarity. By using service type and number of services as grouping criteria, the system transforms the approach to multicast group formation, creating groups that are more homogeneous in terms of content requirements. This parameter change enables more efficient radio resource allocation while maintaining manageable group formation complexity through systematic classification.

AI summary
A system and a method for multimedia broadcast and multicast services is disclosed. The method comprises determining, by a multimedia services computing device, at least one of type of multimedia services and number of multimedia services subscribed by each UE of a plurality of UEs. The method further comprises, creating by the multimedia services system, one or more multicast groups of UEs based on a similarity between the at least one of type of multimedia services and the number of multimedia services subscribed by the each UE. Based on the one or more multicast groups the multimedia messages may be multicast or broadcast.
