ESG Bootstrap Discovery via OMA DM Management Object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Convergence of Broadcasting and Mobile Service (CBMS) systems, there is a need to select an Electronic Service Guide (ESG) bootstrap entry point without relying on the broadcast network, particularly for mobile terminals to access ESG information efficiently.
Innovation Solution
A method and apparatus are provided to discover an ESG bootstrap entry point using Open Mobile Alliance (OMA) Device Management (DM), where a Management Object (MO) is created to connect ESG bootstrap characteristic information with the entry point, enabling terminals to select an appropriate ESG bootstrap entry point through an interactive channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals rely on broadcast network to access ESG information, then ESG bootstrap entry point can be discovered, but terminals cannot efficiently access ESG information in roaming scenarios or without broadcast network
Solution Approach 1:
The patent introduces an intermediary mechanism (OMA DM server and Management Object) that mediates between terminals and ESG bootstrap entry points. The Management Object contains ESG bootstrap characteristic information and entry point URLs, allowing terminals to discover and access ESG information through interactive networks without relying on broadcast networks, thus resolving the contradiction between reliable ESG access and adaptability to different network scenarios
Solution Approach 2:
The patent creates a universal Management Object structure that can serve multiple functions: storing ESG bootstrap characteristic information, providing entry point URLs, supporting both home and roaming scenarios, and enabling access through interactive networks. This multi-functional approach allows the same mechanism to work across different network environments, improving both reliability and adaptability
2Ease of operation
If ESG bootstrap characteristic information is provided through broadcast network, then ESG selection is possible, but interactive network-based ESG discovery is not enabled
Solution Approach 1:
The patent creates a copied representation of ESG bootstrap information in the form of Management Objects stored on OMA DM servers. Instead of terminals directly accessing broadcast network ESG information, they obtain copied ESG bootstrap characteristic information and entry point URLs through interactive networks, making ESG selection easier while distributing the information storage burden across multiple servers
3Adaptability or versatility
If OMA DM mechanism is used for ESG bootstrap entry point discovery, then interactive network-based ESG access is enabled, but system implementation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring Management Objects with ESG bootstrap characteristic information and entry point URLs on OMA DM servers before terminals need them. This allows terminals to simply query and retrieve pre-prepared information through interactive networks, reducing the complexity of real-time ESG discovery while maintaining versatile network access capability

AI summary
A method of providing discovery information of an Electronic Service Guide (ESG) bootstrap entry point is provided. The method includes listing at least one piece of ESG bootstrap characteristic information for an ESG bootstrap proper for a status of a terminal, creating a Management Object (MO), which connects the ESG bootstrap entry point with said at least one piece of ESG bootstrap characteristic information and transmitting the created MO to the terminal through an interactive channel.
