Handoff Address Association for Multi-Session Mobile Handoffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handoff between different communication networks disrupts the state of multiple communication sessions in multiple mode mobile phones, leading to potential disruptions and misassociations of remote parties.
Innovation Solution
A system and method where handoff addresses are associated with communication sessions based on their temporal order of establishment, ensuring seamless handoffs and maintaining session states by configuring these addresses into mobile phones and handoff servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handoff between different communication networks is performed for multiple mode mobile phones, then network connectivity and communication capability are improved, but the state of multiple communication sessions is disrupted and remote parties may be misassociated
Solution Approach 1:
The patent applies preliminary action by pre-configuring handoff addresses into the mobile phone device before handoff operations are needed. The handoff addresses are stored in the device's memory or configuration database, allowing the device to quickly retrieve and use the appropriate handoff address during network transitions without needing to request or negotiate this information in real-time, thereby preventing session state disruption
Solution Approach 2:
The patent introduces handoff addresses as intermediary elements that mediate between the mobile device and communication networks during handoff operations. These addresses serve as stable identifiers that remain consistent across network transitions, allowing the device to maintain session state by consistently referencing the same handoff address regardless of which network is currently serving the device
2Reliability
If handoff addresses are configured into mobile phones and handoff servers, then seamless handoff and session state maintenance are achieved, but device configuration complexity increases
Solution Approach 1:
The patent applies self-service by enabling the mobile device to autonomously manage handoff address associations with communication sessions. The device automatically retrieves pre-configured handoff addresses from its internal storage and applies them to appropriate sessions based on network conditions, without requiring manual user configuration or complex external coordination. This automation reduces the perceived complexity for users while maintaining reliable session state
3Measurement precision
If separate communication of handoff address associations between mobile phone and network is implemented, then handoff accuracy is improved, but network performance and efficiency deteriorate
Solution Approach 1:
The patent eliminates the need for separate real-time communication of handoff address associations by pre-configuring these addresses into the mobile device during manufacturing or initial setup. The device stores multiple handoff addresses locally and automatically selects the appropriate one based on which communication network is currently active, thereby achieving accurate handoff without requiring additional signaling exchanges that would degrade network performance

AI summary
A system and method for associating a handoff address to a communication session includes determining one or more communication sessions are established in a first network. Each of one or more handoff addresses is associated with each of the one or more communication sessions. Associating each of the one or more handoff addresses is according to a temporal order of establishment of the one or more communication sessions.
