Network Proxy for Seamless Active Session Migration Between Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transitioning between different communication terminals, such as from a cell phone to a landline phone, during an active communication session is cumbersome and requires users to manually hang up and re-establish calls, lacking a seamless migration method.
Innovation Solution
A network proxy with a controller manages communication interfaces to receive requests for terminal migration, establishing a new voice channel and terminating the existing connection automatically, allowing seamless migration between terminals without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual hang-up and re-establishment of calls is used for terminal transition, then service transition between wired and wireless is achieved, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The network proxy acts as an intermediary between the first terminal and the second terminal during migration. It receives the migration request, establishes a new voice channel with the third terminal, connects this new channel to the existing voice channel, and automatically terminates the first terminal's connection. This intermediary mechanism enables seamless terminal transition without requiring user intervention to hang up and re-establish calls.
Solution Approach 2:
The network proxy performs preliminary actions by establishing the new voice channel with the third terminal before terminating the connection with the first terminal. This ensures that the communication path is ready in advance, allowing smooth migration without interruption to the active communication session.
2Adaptability or versatility
If manual call re-establishment is used for terminal migration, then terminal switching is achieved, but communication continuity deteriorates and migration time increases
Solution Approach 1:
The network proxy maintains the voice channel connection throughout the migration process, acting as a mediator that allows the transition from the first terminal to the third terminal without breaking the communication flow. This enables terminal switching to occur during an active communication session without requiring hang-up and re-establishment, thereby reducing migration time and maintaining communication continuity.
Solution Approach 2:
The system maintains the voice channel connection continuously during the migration process. The network proxy connects the new voice channel with the third terminal to the existing voice channel, ensuring that the communication action continues uninterrupted throughout the terminal migration, thus eliminating gaps and reducing overall migration time.
3Ease of operation
If automatic migration with network proxy is implemented, then user convenience improves and operation simplicity increases, but system complexity increases
Solution Approach 1:
The network proxy serves as a centralized intermediary that handles all the complex operations of terminal migration, including receiving migration requests, establishing new voice channels, connecting channels, and terminating old connections. By concentrating this complexity in a single network-level component rather than requiring complex logic in each terminal device, the system achieves automatic migration with improved user convenience while managing system complexity in a controlled manner.
4Duration of action of moving object
If seamless migration is achieved through network proxy, then communication continuity is maintained, but network infrastructure complexity increases
Solution Approach 1:
The network proxy acts as a mediating infrastructure component that maintains voice channel connections throughout the migration process. It receives migration requests, establishes new voice channels with the third terminal, connects these new channels to the existing communication flow, and terminates old connections appropriately. This intermediary infrastructure enables seamless migration and maintains communication continuity by ensuring that the voice channel remains active and connected throughout the transition, even though it does increase network infrastructure complexity.

AI summary
An apparatus and method are disclosed for migrating between terminals. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive a request to migrate a first terminal to a third terminal while active communications are taking place on a first voice channel connecting the first terminal to a second terminal, establish a second voice channel with the third terminal, connect the first and second voice channels, and terminate without action of an end user of the first terminal a connection between the first terminal and the first voice channel. Additional embodiments are disclosed.
