Handover Parameter Management for Cellular Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in cellular networks face challenges in maintaining desired quality of service during handovers between base stations, as they lack efficient mechanisms to determine optimal handover parameters based on the type of communication session, leading to potential service interruptions and quality degradation.
Innovation Solution
The implementation of handover parameters, including signal strength thresholds specific to each communication session type, allows base stations to determine when to initiate handovers to another base station, ensuring that communication sessions are transferred only when the new base station meets the required signal strength criteria, thus maintaining service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover parameters are determined based on communication session type, then quality of service during handover is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by determining handover parameters specifically based on the type of communication session (e.g., voice, data, video). Different handover parameters are assigned to different session types, allowing the system to optimize for the specific requirements of each communication type rather than using a one-size-fits-all approach. This resolves the contradiction by improving QoS through targeted parameter selection while managing complexity through type-based classification.
Solution Approach 2:
The patent changes handover parameters dynamically based on the communication session type. The base station determines appropriate handover parameters (such as signal strength thresholds, timing advance values, and power control parameters) according to the session type, enabling adaptive optimization of handover performance for different service requirements while maintaining manageable system complexity through parameterization.
2Reliability
If signal strength thresholds are enforced for handover, then service quality is maintained, but handover speed decreases
Solution Approach 1:
The patent applies preliminary action by pre-determining handover parameters including signal strength thresholds based on the communication session type before handover is needed. The base station configures appropriate thresholds in advance for different session types, allowing the handover process to proceed efficiently by comparing current signal conditions against pre-established criteria rather than calculating thresholds in real-time, thus maintaining both service quality and handover speed.

AI summary
A device may receive information regarding a communication session associated with a user device and may determine, based on the received information, a type of communication session associated with the communication session. The device may determine, based on the determined type of communication session, handover parameters associated with the communication session and may transmit the handover parameters to the user device. The device may receive information associated with the signal information for one or more other devices and may initiate, based on the received information, a handover operation associated with the user device.
