Mobile Device Mobility Management Layer Waiting State Timer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 3GPP mobile communication structure, if the network fails to respond after the mobility management layer of a mobile device enters a waiting state, it becomes passive and unable to provide other services, leading to inefficiencies.
Innovation Solution
A method is introduced where a timer is activated upon entering the waiting state, and if it expires or a specific command is received, the mobility management layer exits the waiting state, allowing the mobile device to resume operations and provide services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobility management layer remains passive in waiting state awaiting network commands, then the device maintains connection readiness, but the device cannot provide other services when network response is delayed or failed
Solution Approach 1:
The patent applies preliminary action by having the mobility management layer proactively transition from waiting state to ready state before network response is actually needed. The layer prepares and switches to ready state after a predetermined waiting period expires, so that when network commands arrive or services need to be provided, the layer is already in the appropriate state to handle them immediately.
Solution Approach 2:
The patent implements dynamics by making the mobility management layer's state transition flexible and adaptive. Instead of remaining statically passive, the layer dynamically transitions between waiting state and ready state based on timing conditions (predetermined waiting period) and network responsiveness, allowing the system to adapt to varying network behaviors while maintaining service provision capability.
2Reliability
If the mobility management layer waits indefinitely for network response, then connection establishment is maintained, but system efficiency decreases due to inability to provide other services
Solution Approach 1:
The patent applies preliminary action by setting a predetermined waiting period that limits the time the mobility management layer spends in waiting state. After this predetermined period expires without network response, the layer proactively transitions to ready state, preventing indefinite waiting and enabling the system to move on to other services or actions.
Solution Approach 2:
The patent implements self-service by having the mobility management layer autonomously manage its own state transitions based on timing conditions. When the predetermined waiting period expires without network response, the layer automatically transitions to ready state without requiring continuous external intervention or network prompting, thereby reducing time loss and improving system efficiency.

AI summary
After a mobility layer of a mobile device enters a waiting state, a timer is activated. The mobile device is configured to await further instructions from a network system before the timer expires and control the mobility layer to leave the waiting state if the timer expires, thereby improving system efficiency.
