Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are unable to determine the type of local network connected to a base station, which hinders the selection of appropriate connection schemes, leading to suboptimal network access and user experience.
Innovation Solution
A method and device that enable a base station to determine and indicate the type of local network to User Equipment (UE) through high-layer signaling during handover, using modules within the Home NodeB (HNB) and Home evolved NodeB (HeNB) to transmit information about the network type in RRCConnectionReconfiguration messages, allowing the UE to receive and process this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the base station does not indicate the local network type to the UE, then the network configuration remains simple, but the UE cannot determine the network type and cannot select appropriate connection schemes
Solution Approach 1:
The base station performs preliminary action by determining and indicating the local network type to the UE before the UE needs to establish a connection. This is achieved by setting the r9Hnb-Net field in the SIB9 broadcast message during the base station's configuration phase, so that when the UE reads this system information, it already possesses the necessary network type information without needing to perform complex detection or trial connections.
Solution Approach 2:
The patent uses system information broadcast (SIB9) as an intermediary carrier to transmit the network type indication from the base station to the UE. This intermediary mechanism allows the base station to convey network type information in a standardized, publicly available channel that the UE can read without requiring dedicated signaling or complex interaction protocols.
2Productivity
If the UE attempts to access networks without knowing the network type, then the connection process is simpler, but the connection efficiency decreases due to unnecessary attempts
Solution Approach 1:
The base station performs preliminary action by determining and indicating the local network type to the UE before the UE needs to establish a connection. This is achieved by setting the r9Hnb-Net field in the SIB9 broadcast message during the base station's configuration phase, so that when the UE reads this system information, it already possesses the necessary network type information without needing to perform complex detection or trial connections.
Solution Approach 2:
The system provides feedback to the UE about the network type configuration through the r9Hnb-Net field in the broadcasted SIB9 message. This feedback mechanism allows the UE to understand the current network type (home network, local Internet network, or both) and adjust its connection strategy accordingly, eliminating unnecessary connection attempts and reducing access time.
3Ease of operation
If the base station provides detailed network type information, then the UE can make informed connection decisions, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the essential network type information from the complex network configuration and places it in a dedicated, easily readable field (r9Hnb-Net) within the existing SIB9 broadcast message. This extraction approach provides the UE with just the necessary information for connection decisions without overwhelming it with unnecessary configuration details, maintaining simplicity while enabling informed decision-making.
Solution Approach 2:
The patent applies local quality by tailoring the information provision to the specific needs of the UE at different operational states. The r9Hnb-Net field is specifically designed to provide network type information that is relevant and actionable for the UE, whether it is in idle mode reading broadcast messages or in connected mode needing connection guidance. This localized information approach ensures ease of operation without unnecessary complexity.

AI summary
The present application discloses a method and an equipment for processing the local network type of a base station (BS). The method comprises: when a BS has determined its local network type, it indicates to a user equipment (UE) said local network type; and when the UE receives the indication carrying said local network type of the BS, it can determine, according to said indication, the local network type of the BS. The present application solves the problem of a user being unable to acquire the type of network connected to a BS and accordingly being unable to determine the corresponding connection means, and enriches user experience.
