Wireless Signaling Collision Handling via Access Type Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the occurrence of message collisions between different access types leads to packet loss, increased latency, and disruptions in communication, particularly when 3GPP and non-3GPP access technologies are used simultaneously, resulting in out-of-sync scenarios and poor user experiences.
Innovation Solution
The system and method involve transmitting signaling messages with different access types between User Equipment (UE) and the network entity, identifying the access types, and synchronizing them to process messages in parallel or re-trigger them, ensuring seamless communication by handling collisions through parallel processing or re-triggering of signaling messages.

Engineering Contradiction Analysis
1Productivity
If signaling messages with different access types are transmitted simultaneously between UE and network entity, then communication efficiency is improved, but message collisions occur leading to packet loss and increased latency
Solution Approach 1:
The system performs preliminary identification of access types in signaling messages before processing them. By determining whether messages belong to 3GPP or non-3GPP access types in advance, the system can apply different handling procedures to prevent collisions, thereby maintaining both communication efficiency and message delivery reliability
Solution Approach 2:
The signaling message processing is segmented into different pathways based on access type identification. Messages are divided into 3GPP access type messages and non-3GPP access type messages, which are then processed independently through separate procedures, preventing interference and collisions between different access types
2Reliability
If message collisions are handled by sequential processing, then packet loss is reduced, but latency increases
Solution Approach 1:
The system dynamically adjusts the processing approach based on access type identification. For compatible messages, parallel processing is enabled to minimize latency. For conflicting messages, the system dynamically switches to selective re-triggering or sequential processing to ensure reliability, creating a flexible adaptive processing mechanism
Solution Approach 2:
The system changes the processing parameter (parallel vs. sequential) based on the identified access types of colliding messages. When messages have different access types, parallel processing is applied to reduce latency. When messages have the same access type, sequential processing with re-triggering is applied to ensure reliable delivery

AI summary
A method for handling collision of signaling messages between a user equipment (UE) and a network entity is disclosed. The method includes transmitting a first signaling message comprising a first access type and a second signaling message comprising a second access type different from the first access type. The UE is registered on a network for the first access type and the second access type. The method also includes determining that the first access type and the second access type correspond to different access types. The method further includes processing the first signaling message and the second signaling message based on the determination by processing of the first signaling message and the second signaling message in parallel or re-triggering one or more of the first signaling message or the second signaling message.
