Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile terminals cannot concurrently handle voice calls and data services, leading to interruptions in data services when a voice call is initiated, especially during important data downloads.

Innovation Solution

A method and apparatus that detect data service connections on mobile terminals and notify calling devices to re-initiate calls as video calls, allowing concurrent voice and data services by using a network-side detection module and notification module to manage voice and data concurrency functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile terminal prioritizes voice call over data service, then the voice call quality is improved, but the data service is interrupted

Engineering Contradiction:

Improvevoice call qualityVSAvoiddata service continuity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the service type parameter from traditional voice call to video call, which allows concurrent transmission with data services on different frequency points, thereby maintaining data service continuity while providing voice communication functionality

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments the communication service into audio stream and video stream components, allowing selective transmission where only audio is sent during data connections, preserving data service while maintaining voice communication capability

Inventive Principle:

Principle #1Segmentation

2Reliability

If the mobile terminal interrupts data service for voice call, then the voice call can be established, but data loss occurs

Engineering Contradiction:

Improvevoice call establishmentVSAvoiddata loss

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The network side performs preliminary detection to identify whether the terminal is engaged in data service before establishing a call, and proactively selects video call mode to prevent data interruption before it occurs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network side acts as an intermediary that detects data service status and mediates the call establishment process by selecting appropriate call types (video call instead of voice call) to avoid interrupting ongoing data services

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method and apparatus for realizing concurrency of voice and data are disclosed, wherein the method includes: step A, a network side receiving a voice call request, and when detecting that a called mobile terminal of the voice call request is carrying out a data service connection, executing step B; step B, the network side notifying a calling mobile terminal of the voice call request of a situation that the called mobile terminal is carrying out the data service connection, and prompting the calling mobile terminal to re-initiate a call in a manner of a video call simultaneously. The present invention achieves that the called mobile terminal can notifying the calling mobile terminal of the situation that the called mobile terminal is in the data connection and does not want the data connection to be interrupted when the called mobile terminal is carrying out the data service connection.
