Solution Overview

Problem

Current methods for mobile terminals to receive MBMS service data lack a practical and efficient method for testing and verifying service capabilities, particularly in different connection states, which affects the reliability and effectiveness of MBMS service delivery.

Innovation Solution

A method and system that involves a system simulator informing the mobile terminal to establish a wireless point-to-point service channel, transmitting MBMS service data, and detecting the terminal's state to ensure normal reception, utilizing specific information elements and channels like DCCH and DTCH to manage service activation and data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the terminal initiatively requests to communicate with SS to receive MBMS service, then the service activation process is simplified, but the terminal cannot properly test and verify its service capability in different connection states

Engineering Contradiction:
Improveservice activation processVSAvoidservice capability verification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the MBMS service reception process into multiple connection states ( CELL_DCH state and PS-DCCH+DTCH_DCH state), allowing the terminal to test and verify its service capability in each state separately. This segmentation enables comprehensive verification while maintaining the simplified activation process through the SS notification mechanism.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the SS notifies the terminal to start receiving MBMS service via different logic channels in different connection states, then the service can be delivered in various scenarios, but the complexity of service management increases

Engineering Contradiction:
Improveservice delivery in various scenariosVSAvoidservice management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where the SS notifies the terminal of MBMS service activation through specific logic channels (DCCH for CELL_DCH state, DTCH for PS-DCCH+DTCH_DCH state) based on the terminal's current connection state. This feedback mechanism enables adaptable service delivery while managing complexity through state-dependent channel selection.

Inventive Principle:
Principle #23Feedback
