Solution Overview
Problem
Dual-standby mobile terminals cannot facilitate conference calls between mobile devices on different networks, limiting multi-party conversations and data sharing across various communication networks.
Innovation Solution
A multi-standby mobile terminal with two communication modules for distinct networks, a control unit, vocoder, codec, and memory units for voice signal and data transfer, enabling loopback processes and data sharing between devices on different networks, acting as a host for voice and data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-standby mobile terminal communicates with mobile terminals on different networks separately, then it can maintain connections with multiple networks, but it cannot facilitate conference calls between mobile terminals on different networks
Solution Approach 1:
The mobile terminal acts as an intermediary device between mobile terminals on different networks. It receives voice packets from one network, converts them to the appropriate format, and transmits them to the other network, enabling conference calls across network boundaries without requiring direct inter-network communication protocols
Solution Approach 2:
The mobile terminal performs multiple functions simultaneously: it acts as a regular mobile terminal for its home network while also serving as a gateway or bridge for inter-network communication. This multi-functionality allows it to facilitate conference calls between different networks while maintaining its primary communication capabilities
2Reliability
If a dual-standby mobile terminal supports simultaneous communication with multiple networks, then it provides greater availability, but it cannot enable data sharing between mobile terminals on different networks
Solution Approach 1:
The mobile terminal serves as a data intermediary that receives data packets from mobile terminals on one network, stores or processes them temporarily, and forwards them to mobile terminals on another network. This mediation enables data sharing across networks while maintaining reliable simultaneous connections to multiple networks
Solution Approach 2:
The mobile terminal creates copies of data packets received from one network and transmits these copies to mobile terminals on another network. This copying mechanism enables data sharing without requiring direct network-to-network data transmission paths, thus maintaining service availability on both networks simultaneously
3Stability of the object's composition
If mobile terminals on different networks are connected separately, then each connection is stable, but the mobile terminals cannot join a conference call together
Solution Approach 1:
The mobile terminal merges separate voice packet streams from different networks into a unified conference call session. It combines the audio data from multiple sources, manages the call signaling, and coordinates the interaction between participants on different networks, enabling multi-party communication while preserving the stability of individual network connections

AI summary
A multi-standby mobile terminal and a method for providing a host function between different networks in a multi-standby mobile terminal are provided. The method includes creating a call from a first mobile terminal, as a multi-standby mobile terminal, to a second mobile terminal on a first network and to a third mobile terminal on a second network, outputting a received voice signal through a speaker from the first mobile terminal, when the voice signal is received from one of the second mobile terminal and third mobile terminal, and, transmitting, from the first mobile terminal, the received voice signal through a loopback process to the one of the second mobile terminal and third mobile terminal that does not transmit the voice signal.
