Push-to-talk attachment queue for simultaneous data and voice transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current push-to-talk voice communication services in wireless networks do not allow users to attach or send data objects such as pictures, video, e-mails, contacts, and documents simultaneously with voice messages, and do not enable sending these data objects to multiple recipients at once.
Innovation Solution
Implementing a PTT attachment queue in mobile stations that automatically stores and sends data objects with push-to-talk voice messages, allowing simultaneous transmission with voice data and enabling multiple recipients to receive these data objects during existing voice communication sessions, even when the mobile station is offline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users send data objects separately from push-to-talk voice messages using e-mail, SMS or MMS, then data objects can be transmitted, but it requires additional data traffic events and increases network traffic
Solution Approach 1:
The patent combines data object transmission with push-to-talk voice message transmission by integrating a data object attachment queue into the PTT system. When a user sends a PTT voice message, associated data objects (pictures, video, audio, e-mails, contacts, documents) are automatically attached and transmitted in the same network event, merging what were previously separate communication channels into a unified transmission process.
Solution Approach 2:
The push-to-talk system is enhanced to perform multiple functions: it now handles both voice communication and data object transmission through a single interface and communication channel. The PTT attachment queue enables the system to universally handle various data types (images, video, audio, documents, contacts) alongside voice messages, eliminating the need for separate e-mail, SMS, or MMS applications.
2Adaptability or versatility
If users send data objects to multiple recipients, then comprehensive information distribution is achieved, but it requires separate transmission events for each recipient
Solution Approach 1:
The system merges multiple data object transmissions to different recipients into a single network event. The PTT attachment queue allows a user to attach data objects to a PTT voice message and specify multiple recipients; the system then transmits the same data object set to all recipients simultaneously in one communication event, rather than requiring separate transmissions to each recipient.
3Productivity
If a single communication channel is used for both voice and data, then network efficiency is improved, but floor control complexity increases for push-to-talk
Solution Approach 1:
The system performs preliminary actions by pre-queuing data objects in the PTT attachment queue before the actual PTT voice transmission occurs. This allows data objects to be prepared, validated, and ready for attachment in advance, so that when the PTT message is sent, the data objects are automatically attached without adding complexity to the real-time floor control mechanism during the actual voice communication.

AI summary
Methods and computer-readable mediums for processing push-to-talk voice messages are provided. According to one method, a first mobile station receives a push-to-talk voice message from a second mobile station, determines that a data object is attached to the push-to-talk voice message, determines a type of the data object, and stores the data object in a PTT attachment queue of the first mobile station, based upon the determined type of the data object, which may be a picture, video data, audio data, e-mail, document, contact, or the like.
