Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems lack effective methods for providing location-aware tracking and services, particularly in integrating location-based services with IP multimedia residential gateways, which limits the ability to manage and secure access to services based on device locations.
Innovation Solution
An IP multimedia gateway device and method that determines the location of communication devices, generates maps for display, communicates content based on location, and restricts access by associating locations with devices, detecting cloned devices and managing service access accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location-based services are integrated into IP multimedia residential gateways, then service functionality and user experience are improved, but system complexity increases
Solution Approach 1:
The patent combines location determination functionality, service profile management, and access control mechanisms within the IP multimedia residential gateway. The gateway integrates multiple subsystems including location information handling, service profile storage, and device identification capabilities into a unified architecture, allowing coordinated operation of location-aware services without requiring separate distributed systems.
Solution Approach 2:
The IP multimedia residential gateway is designed to perform multiple functions beyond basic connectivity, including location determination, service profile management, device cloning detection, and access control. This multi-functional approach consolidates what could be separate specialized systems into a single versatile platform, reducing overall system complexity while maintaining service adaptability.
2Measurement precision
If location tracking and service profiles are stored in the gateway, then service delivery accuracy is improved, but information storage requirements and processing load increase
Solution Approach 1:
The patent extracts and stores only essential location-based service information in the gateway, such as service profiles, location thresholds, and device identification data. Rather than storing complete location histories or detailed service configurations, the system maintains minimal necessary information locally while relying on network connections for comprehensive service delivery, thus reducing storage requirements while maintaining accuracy.
3Reliability
If access control based on location association is implemented, then service security is improved, but processing time for access decisions increases
Solution Approach 1:
The system pre-associates device identifiers with location information and service profiles before access requests occur. By establishing these associations in advance and maintaining them in readily accessible storage within the gateway, the system eliminates the need for complex real-time location verification during access decisions. When a device seeks access, the gateway can quickly match the device identifier against pre-stored associations, enabling fast security decisions without extensive processing.

AI summary
In an IP multimedia gateway, locations corresponding to communicatively coupled communication devices are determined and transmitted to a service provider device (SPD) that provides services to the communication devices. Communication devices receive location based service profiles from the SPD based on the determined locations. Services content from the SPD is communicated with the communication devices and/or with the SPD, based on the profiles. The determined locations are received from communication devices which may be local or remote. A device location map is generated to be displayed by communication devices. The gateway may be integrated in a set-top-box / digital television that displays the determined locations. Content is communicated to communication devices based on their location. The SPD may provide content and/or control information for communication device services. Locations are associated with client devices for detecting cloned client devices where determined locations are different than associated locations and/or for restricting services based on location.
