Caller Image Delivery via Separate Voice Data Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks based on CDMA technology face challenges in delivering real-time voice calls with data due to limitations in simultaneous voice and data communication capabilities, leading to high power consumption and reduced user experience, especially when using SMS for data delivery.
Innovation Solution
Establishing a dedicated data path between the mobile communication network and the mobile device to deliver caller-specific image content and data in real-time, allowing for separate channels for voice and data communications, enabling the display of caller images and information with incoming calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If CDMA networks deliver voice calls using traditional circuit-switched technology, then voice communication is reliable, but real-time data delivery with incoming calls is not supported
Solution Approach 1:
The network communication path is segmented into separate channels: a circuit-switched channel for voice call delivery and a packet-switched data channel for real-time data delivery. This segmentation allows voice and data to traverse different network paths simultaneously, resolving the contradiction between voice reliability and data versatility.
Solution Approach 2:
A message server acts as an intermediary component that receives caller ID information, retrieves associated image content, and delivers both voice call setup information and data content to the mobile device. This intermediary enables coordinated delivery of voice and data without direct conflict in the network infrastructure.
2Adaptability or versatility
If specialized mobile devices operate simultaneously in two different modes for voice and data, then real-time voice and data communication is achieved, but power consumption increases and cost rises
Solution Approach 1:
The mobile device uses its existing dual capability (circuit-switched voice receiver and packet-switched data receiver) for their intended purposes separately, rather than requiring specialized hardware that operates both modes simultaneously. The network coordinates delivery so the device processes voice and data through its standard multi-functional architecture, avoiding excessive power consumption.
3Adaptability or versatility
If SMS technology is used to deliver data portion of messages with incoming calls, then data delivery is possible, but the amount or kind of data is limited and system performance decreases
Solution Approach 1:
The data delivery mechanism changes from SMS protocol constraints to unrestricted packet-switched data transmission. This parameter change in the communication protocol allows significantly larger data quantities (including high-resolution images and multimedia content) to be delivered with incoming calls, while maintaining system performance through efficient separate channel processing.

AI summary
Systems and techniques are provided for delivering image content and other caller-specific data in real-time with an incoming voice call for a mobile device configured to receive voice calls and data through separate channels of the mobile communication network. In response to receiving a call request from an originating device for a voice call to a recipient mobile device, it is determined whether a database in the mobile communication network includes a caller-specific image associated with a caller at an originating mobile device. When the database is determined to include the caller-specific image, the image is sent via a network data connection to the recipient mobile device for display as part of an incoming call notification at the device. The voice call from the originating mobile device is allowed to proceed to the recipient mobile device, only after the caller-specific image is sent to the recipient mobile device.
