Network Handover Preparation via Difference Group Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handover procedures in telecommunication networks often result in service interruptions due to the disconnection from a serving base station before connection to a target base station is established, leading to reduced network quality and service disruptions.
Innovation Solution
A network apparatus comprising a detecting, selecting, receiving, determining, and sending device to identify and prepare target base stations not initially selected by the network, ensuring they are ready for handover by sending preparation information and confirmation messages, including urgent confirmations for fast ranging, to minimize service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile station disconnects from the serving base station to handover to a target base station, then the handover procedure can be completed, but service interruption occurs during the transition
Solution Approach 1:
The network apparatus performs preliminary actions by identifying potential target base stations and sending preparation information to them before the handover is actually executed. This advance preparation ensures that target base stations are ready to immediately accept the mobile station, minimizing service interruption time while ensuring reliable handover completion.
2Reliability
If the network apparatus prepares additional target base stations beyond initial selections, then service quality is maintained during handover, but network complexity increases
Solution Approach 1:
The network apparatus changes the parameter of target base station selection by considering multiple potential targets and their preparation states, rather than relying on a single predetermined target. This flexible approach maintains service quality by having backup options while managing complexity through dynamic parameter adjustment based on network conditions.
3Ease of operation
If the handover procedure follows traditional protocols, then the procedure is straightforward, but service interruptions cannot be avoided
Solution Approach 1:
The network apparatus acts as an intermediary by coordinating between the mobile station and multiple target base stations. It sends preparation information to potential targets and manages the handover process, ensuring service continuity while maintaining procedural simplicity through centralized coordination rather than complex peer-to-peer negotiations.
