Paging Enhancement for Signaling Optimization in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in signaling optimizations, particularly in user equipment (UE) centric mobility and light connection modes, where explicit connection suspension/resumption messages do not minimize signaling load effectively, and there is a lack of clarity on the signaling procedures for entering and returning from these modes.
Innovation Solution
A method where a network element identifies and indicates a suitable signaling procedure to user equipment (UE) in response to a paging message, allowing dynamic selection of procedures to minimize signaling load or utilize UE capabilities, using explicit or implicit mechanisms, such as RRC connection setup, resume, or re-establishment requests, based on context availability and UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit connection suspension/resumption signaling is used, then the UE can maintain RRC connection during mobility, but the signaling load increases
Solution Approach 1:
The patent extracts the connection suspension/resumption indication from separate explicit signaling messages and integrates it into the existing paging message structure. This removes the need for additional dedicated suspension/resumption signaling while maintaining the same functional capability, thereby reducing overall signaling load.
Solution Approach 2:
The patent combines the connection suspension/resumption indication with the paging message into a single signaling transmission. By merging these functions, the system eliminates redundant signaling messages and reduces the total quantity of signaling required while maintaining both paging and connection state management capabilities.
2Quantity of substance
If autonomous entry to light connected mode is allowed, then signaling load is reduced, but clarity on procedures for entering and returning to RRC connected state is lost
Solution Approach 1:
The patent implements feedback mechanisms where the network provides clear indications to the UE about the expected response procedures through the paging message. The UE responds based on the indication received, creating a feedback loop that maintains procedure clarity without requiring extensive explicit signaling about the autonomous transition.
Solution Approach 2:
The patent uses parameter changes in the paging message (such as indication fields) to convey procedural information dynamically. By encoding procedure information in existing message parameters, the system maintains clarity about expected UE responses while avoiding the need for separate procedure definition messages.
3Speed
If UE context is stored in both UE and eNB during light connected state, then connection can be quickly re-established, but signaling optimization is compromised when context cannot be fetched
Solution Approach 1:
The patent introduces dynamic decision-making where the network element determines the appropriate response procedure based on current conditions, including whether UE context can be fetched. The system dynamically selects between different response procedures (such as context request vs. direct re-establishment) based on real-time context availability, optimizing both speed and signaling load adaptively.

AI summary
Various communication systems may benefit from optimizations, such as signaling optimizations. For example, certain wireless communication systems may benefit from paging enhancement for signaling optimization. A method can include identifying, by a network element, a procedure to be used by a user equipment as a response to a paging message. The method can also include indicating the procedure from the network element to the user equipment.
