Cell ID Signaling in ESG Fragments for Location-Specific Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack a standardized method for providing location-specific information across varying communication protocols, leading to inaccuracies in delivering location-dependent content to mobile users.
Innovation Solution
A method and system for transmitting program or service data and corresponding Electronic Service Guide (ESG) fragments to a subscriber terminal based on Cell ID or group of Cell IDs, ensuring accurate delivery of location-specific information using a network management module that allocates services to the correct location within the communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location-specific information is delivered using existing communication systems, then users can receive location-dependent content, but the delivery is inaccurate due to lack of standardized location identification across different communication protocols
Solution Approach 1:
The patent applies universality by creating a standardized location identification method using Cell ID that works across multiple communication protocols including MBMS, BCMCS, and DVB-H. The ESG (Electronic Service Guide) is enhanced to include location information that can be universally interpreted by different communication systems, allowing a single standardized approach to serve multiple protocol families simultaneously.
Solution Approach 2:
The patent changes the parameter of location identification from protocol-specific methods to a standardized Cell ID parameter. By modifying the ESG structure to include standardized location fields and using Cell ID as the common denominator for location identification, the system achieves both accuracy and cross-protocol compatibility.
2Adaptability or versatility
If a standardized location identification method is implemented across all communication systems, then cross-protocol compatibility improves, but the complexity of integrating multiple protocols increases
Solution Approach 1:
The patent uses the ESG (Electronic Service Guide) as an intermediary structure that mediates between different communication protocols and the location identification system. The ESG contains standardized location information fields that act as a common interface, allowing different protocols to interact with location data through a unified mechanism without requiring direct integration between protocols.
Solution Approach 2:
The patent segments the location identification function into separate, standardized fields within the ESG structure. By dividing the location information into discrete, standardized parameters (such as Cell ID fields), the system reduces integration complexity while maintaining cross-protocol compatibility, as each protocol only needs to handle specific standardized fields rather than the entire location system.
Data Source
AI summary
Provided are apparatuses and methods for providing a program or service transmission with associated ESG fragment(s) to a receiver within a designated location. Parameter, elements or sub-elements may be included in a service guide or other data fragment indicating the location within which the program, service and corresponding ESG fragment(s) may be broadcast. For example, a Cell ID may be indicated as an element or sub-element in an ESG fragment to indicate the location in which a program or service may be broadcast. Also, Cell IDs may be grouped to indicate a larger region in which to broadcast a program or service and corresponding ESG fragment(s) in a service guide.
