RCS Location Sharing Criteria for Policy-Compliant Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing location sharing using Rich Communications Services (RCS) lack defined criteria for when, how, and to whom location information should be shared, leading to inefficiencies and conflicts with network, regulatory, and user policies.
Innovation Solution
Implementing methods and apparatus that determine criteria and rules for RCS location sharing based on events, device attributes, network attributes, and user policies, using Session Initiation Protocol (SIP) messaging to manage location updates and encrypt sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location information is shared using RCS protocol without defined criteria, then location sharing capability is enabled, but network efficiency and device efficiency deteriorate due to unmanaged location updates
Solution Approach 1:
The patent implements dynamic location sharing criteria that adjust based on event detection, device attributes, network attributes, and user policies. The system transitions from static location sharing to dynamic control where location updates are triggered by specific events (e.g., device motion, network changes) and filtered through multiple policy layers, thereby improving network efficiency while maintaining location sharing capability.
Solution Approach 2:
The patent changes the parameters of location sharing by introducing multiple criteria dimensions (event-based triggers, device attributes like battery level and motion state, network attributes like signal strength, and user policy preferences). These parameter changes enable selective location sharing that optimizes network resource usage while preserving essential location sharing functionality.
2Ease of operation
If location information is shared without policy filtering, then location sharing is simplified, but conflicts with network, regulatory, and user policies arise
Solution Approach 1:
The patent introduces an intermediary policy filtering mechanism that sits between location sharing requests and the actual sharing execution. This intermediary layer evaluates multiple policy dimensions (network policies, regulatory requirements, user preferences) and mediates the location sharing decision, ensuring compliance while maintaining ease of operation through automated policy management.
Solution Approach 2:
The patent segments the location sharing decision-making process into distinct policy layers (network policy, regulatory policy, user policy) and event-based triggers. Each layer independently evaluates specific criteria, and the combined results determine whether location sharing proceeds. This segmentation makes the complex policy compliance process manageable and systematic.
3Measurement precision
If comprehensive location sharing criteria are implemented, then location sharing precision and control are improved, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the device automatically detects events (motion, network changes), evaluates its own attributes (battery level, signal strength), and applies policy filters without requiring constant user intervention. This automation achieves precise location sharing control while minimizing the perceived complexity for users.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring location sharing criteria, event triggers, and policy rules before actual location sharing occurs. The device pre-evaluates multiple criteria dimensions and establishes decision-making frameworks in advance, which reduces the computational burden during active location sharing and simplifies the overall system operation.
4Device complexity
If location sharing is implemented without event detection, then device operation is simpler, but location sharing timeliness and relevance deteriorate
Solution Approach 1:
The patent implements periodic event detection mechanisms that monitor device attributes (motion state, battery level) and network attributes (signal strength, connectivity) at scheduled intervals. This periodic monitoring enables timely location sharing updates without requiring continuous complex processing, balancing timeliness with device operation simplicity.
Solution Approach 2:
The patent establishes feedback loops where event detection results and location sharing outcomes are continuously monitored and used to adjust future location sharing decisions. This feedback mechanism improves location sharing timeliness by automatically responding to changing conditions while maintaining relatively simple device operation through automated adaptive control.
