Solution Overview

Problem

Current mobile devices often suspend packet data activities during emergency calls, preventing automatic notification of emergency contacts, especially in networks that do not support concurrent voice and data services.

Innovation Solution

A method and apparatus that allow a mobile device to initiate a packet data call to notify user-defined emergency contacts during or after an emergency voice call, using network capabilities to send data messages without impacting the voice call, and automatically switching to a network that supports concurrent voice and data if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile device suspends packet data activities during emergency calls, then the emergency voice call reliability is improved, but the automatic notification of emergency contacts cannot be sent

Engineering Contradiction:

Improveemergency voice call receptionVSAvoidemergency contact notification

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The mobile device determines network capability to support concurrent voice and packet data sessions before placing the emergency call. If the network supports concurrent sessions, the device preliminarily establishes packet data connectivity so that emergency contact notifications can be sent automatically during the emergency call without suspending data activities.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mobile device dynamically adjusts its operation mode based on network capability. When the network supports concurrent sessions, the device maintains both voice and packet data activities simultaneously. When the network does not support concurrent sessions, the device suspends packet data activities during the emergency call and sends notifications after the call ends.

Inventive Principle:

Principle #15Dynamics

2Extent of automation

If the mobile device sends packet data during emergency calls, then automatic notification of emergency contacts is enabled, but the emergency voice call may be disrupted in networks that do not support concurrent sessions

Engineering Contradiction:

Improveautomatic emergency contact notificationVSAvoidemergency voice call quality

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The mobile device performs a preliminary check of network capability to support concurrent voice and packet data sessions before initiating the emergency call. This preliminary determination allows the device to configure the appropriate operation mode in advance, ensuring that automatic notification can be sent without disrupting the voice call when the network supports concurrent sessions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network capability determination acts as an intermediary condition that mediates between the desire to send automatic notifications and the need to maintain voice call quality. Based on this intermediary assessment, the device selectively enables or disables packet data activities during the emergency call.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the mobile device waits for network support for concurrent sessions, then both voice and data can be sent simultaneously, but the notification is delayed until the voice call ends in non-concurrent networks

Engineering Contradiction:

Improveconcurrent voice and data transmissionVSAvoidnotification timing

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The mobile device determines network capability preliminarily before placing the emergency call. If the network supports concurrent sessions, the device establishes packet data connectivity in advance, enabling immediate automatic notification during the call. If the network does not support concurrent sessions, the device prepares to send notifications after the call ends, minimizing delay.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mobile device dynamically adjusts the notification timing based on network capability. In networks supporting concurrent sessions, notifications are sent immediately during the call. In networks not supporting concurrent sessions, notifications are sent after the call ends, optimizing the balance between concurrent transmission capability and notification timing.

Inventive Principle:

Principle #15Dynamics

AI summary

A method and apparatus for automatically sending a data message from a mobile device to at least one recipient during or soon after an emergency voice call, the method having the steps of: determining whether the data message can be sent over the network during the emergency voice call, and if yes, creating and sending the data message; and if no, waiting until either the mobile device connects to a new network, wherein the method proceeds back to said determining step, or until the voice call has ended and then creating and sending the data message.
