Service Delivery System Using Broadcast Segmentation for Mobile Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limitations on Over-the-Air (OTA) resources and available power and storage for mobile devices make unicast content delivery challenging, as they are not efficiently scalable for widespread distribution of multimedia services.
Innovation Solution
A method and apparatus for selectively receiving and caching content items associated with a service, using objective measures of user interest, such as popularity and freshness, to mimic a unicast or multicast experience, allowing mobile devices to efficiently distribute content to a population of devices, even with limited resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unicast content delivery is used to provide personalized user experience, then user experience quality is improved, but scalability and resource efficiency deteriorate due to limited OTA resources, power, and storage
Solution Approach 1:
The patent segments content delivery into two parts: popular content items are delivered via efficient broadcast to multiple users simultaneously, while personalized content selections are delivered via unicast to individual users. This segmentation resolves the contradiction by applying the most efficient delivery method to each content type, achieving both scalability for popular content and personalized experience for user-specific content.
Solution Approach 2:
The patent implements partial unicast action by delivering only the specific content items that users have selected from the broadcasted popular content, rather than delivering complete personalized content libraries. This partial action approach maintains scalability while providing personalized experience for the most relevant content.
2Productivity
If broadcast content delivery is used to improve scalability, then resource efficiency is improved, but ability to provide personalized user experience deteriorates
Solution Approach 1:
The system segments the content delivery process into a broadcast phase (delivering popular content efficiently to all users) and a unicast phase (delivering user-selected personalized content). This segmentation allows the system to achieve resource efficiency through broadcast while maintaining personalized user experience through the subsequent unicast delivery of selected content items.
Solution Approach 2:
The patent introduces an intermediary mechanism where mobile devices receive broadcast content locally and then request additional personalized content items from the network based on user selection. This intermediary approach allows the system to combine broadcast efficiency with unicast personalization, resolving the contradiction between resource efficiency and personalized experience.
3Ease of operation
If complete content libraries are delivered to each mobile device, then user experience quality is improved, but device storage requirements and power consumption deteriorate
Solution Approach 1:
The patent applies preliminary action by broadcasting popular content items to mobile devices in advance, so that when users want to access personalized content, the base content is already available locally. This preliminary delivery of popular content reduces the need for each device to store complete content libraries, thereby reducing storage requirements while maintaining user experience quality.
Solution Approach 2:
The system uses copying by delivering popular content items via broadcast to multiple devices simultaneously, creating local copies on each device without requiring each device to obtain and store the complete content library. This copying approach reduces individual device storage requirements while ensuring content availability for personalized delivery.

AI summary
A service distribution system supports creation of a personalized and virtual service broadcast that can be selectively clipped and cached based on content descriptors of popularity, freshness, etc. A method for selectively receiving broadcast of one or more content items associated with a service to provide a unicast or multicast user experience is described. The method may comprise: detecting a characteristic of a service, or detecting a characteristic of one or more content items, wherein the one or more content items are associated with the service, and wherein the characteristic is generated by a mobile operator and pertains to an objective measure of current user interest, selectively receiving by broadcast, to the mobile device, one or more content items associated with the service based on the characteristic, and storing the one or more content items associated with the service for access through a user interface of the mobile device.
