MCPTT Terminal Baseband Application Processor Segmentation

Solution Overview

Problem

Current MCPTT service terminals face challenges in reducing power consumption, which is crucial for mission-critical communication scenarios, especially in off-network situations where communication infrastructure is unavailable.

Innovation Solution

The terminal employs a baseband processor and application processor to selectively transmit MCPTT service-related messages and perform operations based on the message type and processor state, including controlling the voice codec and managing floor control messages, to minimize power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the application processor continuously processes MCPTT service-related messages, then the service reliability is improved, but the power consumption increases

Engineering Contradiction:

Improveservice reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the message processing function into two segments: the baseband processor handles reception and initial processing of MCPTT service-related messages, while the application processor handles only those messages that require higher-level processing. This segmentation allows the application processor to remain in a low-power state for extended periods while still maintaining service reliability through coordinated processing between the two processors.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The baseband processor performs preliminary actions by receiving and pre-processing MCPTT service-related messages before they are passed to the application processor. This preliminary processing includes determining whether the application processor needs to be activated and preparing messages for selective transmission, thereby reducing the workload on the application processor and extending its idle periods.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If the application processor remains in idle state, then power consumption is reduced, but the response time to process messages increases

Engineering Contradiction:

Improvepower consumptionVSAvoidresponse time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The baseband processor performs preliminary actions by receiving and pre-processing MCPTT service-related messages before they are passed to the application processor. This preliminary processing includes determining whether the application processor needs to be activated and preparing messages for selective transmission, thereby reducing the workload on the application processor and extending its idle periods.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the baseband processor continuously monitors incoming messages and dynamically determines whether to activate the application processor based on message content and current processor state. This feedback loop ensures the application processor is activated only when necessary, optimizing the balance between power consumption and response time.

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the baseband processor handles all MCPTT operations, then power consumption is reduced, but the service functionality is limited

Engineering Contradiction:

Improvepower consumptionVSAvoidservice functionality

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent divides the message processing function into two segments: the baseband processor handles reception and initial processing of MCPTT service-related messages, while the application processor handles only those messages that require higher-level processing. This segmentation allows the application processor to remain in a low-power state for extended periods while still maintaining service reliability through coordinated processing between the two processors.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The baseband processor acts as an intermediary between the radio frequency interface and the application processor. It receives messages, determines their processing requirements, and selectively transmits them to the application processor when needed. This intermediary role enables the system to maintain full service functionality while minimizing the activation time of the power-intensive application processor.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A terminal participates in a group call based on a Mission Critical Push to Talk (MCPTT) service. The terminal includes a baseband processor and an application processor. In some embodiments, the baseband processor receives an MCPTT service-related message from outside and determines whether to transmit the MCPTT service-related message to the application processor. The baseband processor may make the determination based on the MCPTT service-related message or based on an operation state of the application processor. As a result of the determining, some embodiments include performing, by at least one of the baseband processor and the application processor, MCPTT service-related operations.
