Paging ID Generation for Light Connection State Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging mechanisms in LTE systems are not applicable to User Equipment (UE) in a Light Connection (LC) state, as they lack a solution for downlink data delivery, leading to increased signaling overheads and inefficient system performance.
Innovation Solution
The proposed solution involves an evolved Node B (eNB) generating a paging ID and transmitting a paging message to a UE in an LC state when downlink data is received, using dedicated signaling to configure the UE's state and maintain S1 connections, allowing for efficient data transmission and reducing signaling overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a UE is in Light Connection state to reduce signaling overheads, then signaling overheads are reduced, but the existing paging mechanism cannot deliver downlink data to the UE
Solution Approach 1:
The patent segments the traditional connected state into two distinct states: Light Connection (LC) state for minimal signaling overhead and full Connection state for complete data transmission capability. The eNB can transition UE between these states based on data arrival, enabling efficient resource management while maintaining necessary functionality.
Solution Approach 2:
The patent introduces dynamic state transition capability where the UE can switch between LC state and Connection state based on downlink data arrival. This dynamic adaptation allows the system to optimize signaling overhead when no data is present while ensuring reliable data delivery when needed.
2Use of energy by moving object
If the UE monitors paging in DRX mode to save electricity, then energy consumption is reduced, but the UE cannot receive downlink data in LC state
Solution Approach 1:
The patent maintains DRX periodic monitoring behavior for UEs in LC state, allowing them to wake up at predetermined intervals to check for paging messages. This periodic action enables energy-efficient operation while still providing the capability to receive downlink data when the UE is active during the monitoring period.
3Reliability
If the eNB transmits paging message to LC state UE, then downlink data delivery is enabled, but system complexity increases
Solution Approach 1:
The patent extends the existing paging message mechanism to serve dual purposes: traditional idle state UE paging and new LC state UE data delivery. By making the paging message universal for both states, the system avoids creating entirely new signaling procedures, thereby limiting the increase in system complexity.
4Reliability
If the UE enters Connection state to receive data, then data transmission is enabled, but signaling overheads increase
Solution Approach 1:
The patent introduces dynamic state transition capability where the UE can switch between LC state and Connection state based on downlink data arrival. This dynamic adaptation allows the system to optimize signaling overhead when no data is present while ensuring reliable data delivery when needed.
