Autonomous Search Function Management in LTE Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices implementing LTE standards do not clearly distinguish between autonomous search functions (ASFs) used in idle and connected modes, leading to potential disabling of idle mode ASF when connected mode ASF is disabled, which affects the device's ability to independently manage and enable/disable ASFs based on context and system state.
Innovation Solution
A system and method for a mobile device to manage ASFs separately for idle and connected modes, enabling or disabling them based on current mode, whitelist state, and proximity indicators, allowing distinct operations for each mode without affecting the other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous search functions are not clearly distinguished between idle and connected modes, then device complexity is reduced, but reliability of network connectivity deteriorates due to potential disabling of idle mode ASF when connected mode ASF is disabled
Solution Approach 1:
The patent segments the autonomous search function into two distinct functions: idle mode ASF and connected mode ASF. Each function is independently controllable with separate enable/disable flags, allowing the device to maintain reliability by preserving idle mode ASF capability even when connected mode ASF is disabled, while managing complexity through clear functional separation.
2Reliability
If autonomous search functions are clearly distinguished between idle and connected modes, then reliability of network connectivity is improved, but device complexity increases due to separate management requirements
Solution Approach 1:
The patent implements a unified ASF management framework that handles both idle mode and connected mode autonomous search functions through common control mechanisms. The system uses a single control interface that can independently manage both functions, reducing the perceived complexity while maintaining the reliability benefits of distinct function management.
3Ease of operation
If idle mode ASF is disabled when connected mode ASF is disabled, then ease of operation is improved through simplified control, but productivity deteriorates due to loss of cell camping capability
Solution Approach 1:
The patent implements dynamic control of autonomous search functions based on operational context. The system automatically adjusts which ASF is active based on the device's operational state (idle or connected mode), ensuring that the appropriate search function is enabled without requiring manual user intervention. This dynamic adaptation maintains ease of operation while preserving productivity by ensuring the correct ASF remains active for the current operational context.

AI summary
A method for wireless communication in a Long-Term Evolution (LTE) or LTE-equivalent environment which allows a mobile device to manage autonomous search functions (ASF) is disclosed. In an LTE-equivalent environment, a mobile device may function in several modes, including idle and connected. In either mode, the mobile device may need to use an autonomous search function (ASF) to find or exchange information with base stations. The mobile device first determines the mode the current operation pertains to. When modifying the availability of an ASF, the mobile device distinguishes between the modes that will execute the ASF. When calling an ASF, the mobile device determines the availability of that function based on the device's current mode. In idle mode, the mobile device uses the idle mode ASF. Conversely, in connected mode the mobile device uses the connected mode ASF. The two functions are distinctly managed and operated by the mobile device.
