UE Paging Message Identification for Multi-Core Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in current LTE systems cannot connect to different core network entities, which is a challenge as the introduction of a next-generation core (NG-Core) in 5G networks enables multiple core network entities and network slices, requiring a method to identify and establish connections with various core network entities.
Innovation Solution
A message identification method and apparatus that allows UE to receive paging messages, determine the appropriate core network entity, and establish data connections by using identification information such as type, device, or time-frequency resources, enabling access to multiple core network entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE accesses multiple core network entities in 5G network, then service diversity and adaptability are improved, but device complexity and connection management difficulty increase
Solution Approach 1:
The patent segments the core network entities into distinct types (EPC and NG-Core) with clear functional boundaries. Each core network entity type has dedicated identification mechanisms and connection management procedures, allowing the UE to handle multiple entities without overwhelming complexity by treating them as separate, manageable units rather than a monolithic system.
Solution Approach 2:
The patent introduces identification information as an intermediary element that mediates between the UE and multiple core network entities. This identification information acts as a key that enables the UE to distinguish between different entity types and establish appropriate connections, simplifying the interaction complexity while maintaining access to diverse services.
2Measurement precision
If UE determines core network entity from paging message, then connection accuracy is improved, but message processing complexity increases
Solution Approach 1:
The patent extracts identification information as a distinct, separable element from the paging message structure. By taking out the entity identification component as a dedicated field or element within the message, the UE can focus processing on extracting this specific information to determine the target core network entity, rather than analyzing the entire message complexity, thus improving accuracy while managing processing load.
3Stability of the object's composition
If LTE network evolves to eLTE network with NG-Core, then backward compatibility is maintained, but network architecture complexity increases
Solution Approach 1:
The patent implements a universal identification mechanism that works across both EPC and NG-Core entities. The same paging message structure and identification fields can universally indicate different types of core network entities, allowing the network to maintain backward compatibility with LTE/EPC while incorporating new NG-Core functionality without requiring separate message formats or protocols for each entity type.
