Dual Mode Phone Multiparty Call Audio Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not allow for the integration of push-to-talk (PTT) or private calls with interconnect calls on different communication networks, preventing the creation of multiparty calls on dual mode phones.
Innovation Solution
A dual mode communication device with both private and interconnect call capabilities can establish an interconnect call on one network, receive a request for a private call on another network, and mix and route audio signals to enable multiparty calls by using a processor to control the communication and mix microphone inputs with audio from both networks, allowing additional parties to join the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current technology is used for interconnect calls on dual mode phones, then calls can be established on one network, but private calls or push-to-talk calls cannot be completed when already on an interconnect call
Solution Approach 1:
The patent merges interconnect call audio and private call audio into a single multiparty call stream, allowing both networks to operate simultaneously. The audio mixing module combines audio data from the interconnect call (first network) and private call (second network) into one integrated audio stream that can be transmitted to all parties.
Solution Approach 2:
The dual mode phone is enhanced to perform multiple call types and network operations simultaneously. The system can establish interconnect calls on one network while accepting and integrating private calls from another network, creating a universal communication platform that handles multiple protocols and call types through a unified interface.
2Adaptability or versatility
If audio from multiple networks is mixed and routed, then multiparty calls can be created across different networks, but the device must handle complex audio routing and mixing operations
Solution Approach 1:
The audio mixing module serves as an intermediary between the interconnect call audio stream and the private call audio stream. It receives audio data from both networks, performs mixing operations, and outputs a combined audio stream that can be routed to all call parties. This intermediary component simplifies the overall system architecture by centralizing the complex audio routing logic.
3Ease of operation
If push-to-talk activation is used to control multiparty communication, then additional parties can be invited to join, but call control mechanisms become more complex
Solution Approach 1:
The system enables self-service call management where the user can independently invite additional parties to join the multiparty call using push-to-talk activation. The audio mixing module automatically integrates new participants into the existing call stream without requiring manual configuration or complex setup procedures, allowing users to dynamically expand or modify call participants as needed.

AI summary
A method (100) and system (20) for multiparty communication using at least one dual mode communication device includes a dual mode radio (11) having at least a first modem (12) for operation on a first network and a second modem (13) for operation on a second network and a processor (55) coupled to the radio. The dual mode radio can be programmed to establish (102) an interconnect call on a first network between the dual mode radio and a second communication device, receive (104) a request for a private call on a second network from a third communication device, and mix and route (106) audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen. The dual mode radio can be a first modem operating on a CDMA network and a second modem operating on an iDEN network.
