NodeB Broadcasts HNBGW Identifier for Seamless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack an efficient method to notify the core network node of the identification information for HNBGWs, particularly during handover procedures between macro and femto cells, leading to complications in SRNS Relocation and Self-Organizing Network (SON) functions.
Innovation Solution
A wireless communication system where the first NodeB broadcasts system information including an RNC identifier that identifies the HNBGW, allowing user equipment to acquire and transmit this identifier to the second NodeB, enabling efficient identification and notification of HNBGWs within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core network node is notified of HNBGW identification information through existing signaling methods, then handover procedures can be executed, but the system complexity increases and the notification process becomes inefficient
Solution Approach 1:
The patent extracts the HNBGW identification information (RNC identifier) from the system information broadcast by the HNB and transmits it directly to the core network node through the NodeB, bypassing the need for complex intermediary notification mechanisms. This extraction approach simplifies the overall notification system while ensuring reliable handover execution.
Solution Approach 2:
The NodeB acts as an intermediary that receives system information from the HNB and forwards the RNC identifier to the core network node. This intermediary mechanism simplifies the notification process by using existing infrastructure components rather than introducing new complex signaling pathways.
2Ease of manufacture
If manual operator input is used for network configuration, then network construction can be performed, but the time consumption and operational complexity increase
Solution Approach 1:
The system enables self-service configuration by automatically broadcasting HNBGW identification information through system information messages. The core network node automatically receives and processes this information without requiring manual operator input, thereby eliminating configuration time loss while maintaining full network configuration capability.
3Device complexity
If the HNBGW identification information is not efficiently transmitted, then the system architecture remains simple, but the handover procedures and SON functions become complicated
Solution Approach 1:
The HNBGW identification information is included in the system information broadcast before handover operations are initiated. This preliminary transmission of identification data ensures that the core network node has the necessary information readily available, simplifying subsequent handover procedures and SON functions without requiring changes to the overall system architecture.
