ESG Bootstrap IPDC Operator Identification for Mobile Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile broadcasting systems, particularly those using Electronic Service Guides (ESG), face challenges in supporting mobility as terminals often need to retrieve and parse multiple ESG bootstraps to find the correct IPDC operator, especially in roaming scenarios, leading to inefficiencies and lack of interactive ESG support.
Innovation Solution
Incorporating IPDC operator information into the ESG bootstrap, allowing terminals to quickly identify the appropriate IP platform and ESG by including this information within the broadcast service information (PSI/SI), thereby reducing the need for extensive ESG bootstrap parsing and enhancing mobility support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminals retrieve and parse multiple ESG bootstraps to find the correct IPDC operator, then the terminal can identify the appropriate service provider, but the process becomes time-consuming and inefficient especially in roaming scenarios
Solution Approach 1:
The patent applies preliminary action by including IPDC operator information (IPDCKMSID and IPDCOperatorID) in the broadcast service information (PSI/SI) before the terminal needs to retrieve ESG bootstraps. This allows the terminal to pre-identify the correct IPDC operator without having to parse multiple ESG bootstraps, thereby resolving the contradiction between identification accuracy and time consumption.
2Adaptability or versatility
If the system provides comprehensive ESG information for all IP platforms, then the terminal has complete service information, but the device complexity and information processing burden increase
Solution Approach 1:
The patent applies the extraction principle by separating IPDC operator identification information from the complex ESG bootstrap structure and placing it in the simpler broadcast service information (PSI/SI). This allows the terminal to extract only the necessary identification information without processing the entire ESG bootstrap structure, thereby reducing device complexity while maintaining adaptability.
3Loss of information
If the terminal retrieves complete ESG information before identifying the IPDC operator, then the terminal has all service details, but the information acquisition process becomes inefficient and non-interactive
Solution Approach 1:
The patent applies preliminary action by providing IPDC operator identification information in the broadcast service information before the terminal retrieves ESG details. This enables the terminal to first identify the correct operator and then selectively acquire only the relevant ESG information, improving productivity while preventing information loss through a two-stage acquisition process.

AI summary
A method and apparatus for supporting mobility in a mobile broadcasting system in which Electronic Service Guide (ESG) discovery is required. The mobility support is classified into three ways. The first way is to provide roaming information for a local IPDC operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with type information of an ESG, an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the type information of the ESG, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.
