Dual-Standby Mobile Terminal Multiparty Call Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiparty call services limit the number of simultaneous call groups and participants, forcing users to disconnect from existing calls to receive urgent calls, leading to potential missed communications due to full connection channels.
Innovation Solution
A dual standby mobile terminal method that allows simultaneous standby on two networks using two SIM/USIM cards, enabling call diversion to another network when the primary network is in a full state, thus allowing calls to be made or received without disconnecting from existing multiparty calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the mobile terminal participates in the maximum number of multiparty call groups or in a multiparty call with the maximum number of participants, then the network utilization is optimized, but the user cannot make or receive additional calls without disconnecting from existing calls
Solution Approach 1:
The invention divides the call handling capability into two separate network interfaces (first network and second network). When the first network reaches its maximum call capacity, the terminal can segment call requests by routing them through the second network, which has its own independent call capacity. This allows simultaneous participation in maximum call groups on one network while still accepting additional calls on the other network.
Solution Approach 2:
The invention adds a dimensional solution by introducing a second network dimension. Instead of trying to increase capacity within a single network dimension, the system transitions to a multi-dimensional architecture where calls can be distributed across multiple network planes. This dimensional expansion allows the terminal to maintain maximum participation on the primary network while gaining additional call acceptance capability through the secondary network.
2Reliability
If the mobile terminal limits the number of participants in a multiparty call to the maximum number, then the network resource allocation is optimized, but the user experience deteriorates when urgent calls need to be received
Solution Approach 1:
The second network acts as an intermediary channel for urgent calls. When the primary network is at capacity, the system introduces the second network as a mediator to handle additional call requests. This intermediary mechanism allows the system to maintain strict resource allocation on the primary network while providing a backup pathway through the secondary network, thereby preserving both resource optimization and user convenience.
3Device complexity
If the mobile terminal uses a single network for multiparty calls, then the system complexity is minimized, but the productivity of call handling is reduced due to connection channel limitations
Solution Approach 1:
The mobile terminal is designed with multi-functionality by incorporating dual network interfaces that can independently handle call traffic. Each network interface can function autonomously to manage its own set of call groups and participants. This universal design allows the terminal to operate on a single network for simplicity when needed, while simultaneously leveraging both networks to maximize call handling capacity when required, thus achieving both simplicity and high productivity.

AI summary
A multiparty call processing method and mobile terminal implemented with the multiparty call processing method is provided. A multiparty call processing method for a mobile terminal detects a call request to a first network, determines whether the mobile terminal is in a full state of the first network, and sends a call request message to a second network when the mobile terminal is in the full state of the first network.
