Conference Call Initiation via Pre-Setup and Silent Redial
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems do not allow users to add additional participants to a conference call until the initial call is established, leading to poor user experience due to wait times when the initial caller is in poor coverage or does not answer.
Innovation Solution
A method for wireless communication that enables a user to initiate a mobile conference call by adding a third user equipment (UE) to the call before the mobile call is established with the second UE, by sending a cancelation message for the initial mobile call and performing a silent redial to establish the conference call through a conference server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system requires the initial mobile call to be established before allowing addition of participants, then the call establishment process is simplified and reliable, but the user experience deteriorates due to increased wait times when the initial caller is in poor coverage or does not answer
Solution Approach 1:
The system performs preliminary actions by allowing the user to add participants to the conference call before the initial mobile call is actually established. The conference server pre-configures the call setup with multiple participants, so when the initial call is made, all participants are already prepared and can join simultaneously, eliminating the need to wait for sequential establishment.
Solution Approach 2:
The conference server acts as an intermediary that coordinates between multiple users and the mobile network. It manages the complex process of adding participants before call establishment by buffering participant information and coordinating with the mobile network elements, thereby resolving the contradiction between reliability and wait time.
2Loss of time
If the system allows adding participants before the initial call is established, then user experience is improved by reducing wait times, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The conference server serves as an intermediary that handles the complex operations of managing multiple participants, coordinating call setup, and interfacing with mobile network elements. This shifts the complexity from the user equipment to the server, allowing simple client-side implementation while maintaining advanced functionality.
Solution Approach 2:
The conference server performs multiple functions including participant management, call coordination, network element communication, and call setup optimization. By consolidating these functions in a single intermediary system, the patent reduces the complexity burden on individual devices while enabling sophisticated call management.
3Productivity
If the system uses traditional sequential call establishment, then the processing requirements are minimized, but the productivity decreases due to sequential operations required for multi-participant calls
Solution Approach 1:
The system performs preliminary actions by pre-configuring conference call parameters and participant lists before the actual call begins. The conference server prepares the call setup in advance, allowing for parallel processing of multiple participant connections rather than sequential establishment, thereby increasing productivity without proportionally increasing processing power requirements.
Solution Approach 2:
The patent merges multiple call setup operations into a single coordinated conference call establishment process. Instead of handling each participant addition as a separate sequential operation that consumes additional processing resources, the system combines all participant invitations into a unified conference setup, improving productivity while minimizing processing overhead through efficient resource utilization.

AI summary
Certain aspects of the present disclosure provide techniques for improving conference call initiation at a first user equipment (UE). An example method includes initiating a mobile call associated with a second UE, receiving input requesting to add a third UE to the mobile call prior to the mobile call being established with the second UE, and taking one or more actions to establish a mobile conference call with the second UE and the third UE based on the received input prior to the mobile call being established with the second UE.
