Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional MBMS service information reporting schemes are not comprehensive, leading to discontinuities in MBMS service reception for terminal devices, as they only report the latest frequency point of an MBMS service without adequately conveying the reception ability, preventing the network from performing correct service cell configuration.

Innovation Solution

The method involves terminal devices reporting MBMS service reception ability information to network devices, including whether the MBMS frequency point is within their reception scope, allowing the network to re-configure serving cells for continuous service delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the terminal device reports only the latest frequency point of MBMS service, then the reporting scheme is simple, but the service reception continuity is disrupted due to incomplete information

Engineering Contradiction:

Improvereporting scheme complexityVSAvoidservice reception continuity

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The reporting information is segmented into multiple distinct components: MBMS service identification information, MBMS frequency point information, and reception ability information. This segmentation allows each component to serve its specific function while collectively providing comprehensive service continuity assurance without excessive overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Reception ability information acts as an intermediary element that bridges the gap between simple frequency point reporting and comprehensive service configuration. It provides the network with sufficient information to make correct serving cell configuration decisions without requiring the terminal to report overly detailed data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the terminal device reports comprehensive MBMS service information including reception ability, then the service reception continuity is ensured, but the information reporting complexity increases

Engineering Contradiction:

Improveservice reception continuityVSAvoidinformation reporting complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The essential reception ability information is extracted from complex terminal device capabilities and reported to the network. This extraction focuses only on the critical information needed for service continuity (whether the MBMS frequency point is within reception scope), avoiding reporting of unnecessary detailed capability data.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The reporting approach changes from reporting raw terminal capabilities to reporting processed reception ability parameters. The terminal evaluates its reception ability against the reported MBMS frequency point and transmits only the relevant evaluation result, simplifying the information while maintaining reliability.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If the network configures serving cells without reception ability information, then the configuration process is simple, but the MBMS service reception cannot be continuously maintained

Engineering Contradiction:

Improveconfiguration efficiencyVSAvoidservice reception continuity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The terminal device performs preliminary evaluation of its reception ability against the MBMS frequency point before service delivery and reports this information to the network. This preliminary action enables the network to make informed configuration decisions in advance, ensuring service continuity without requiring complex real-time adjustments.

Inventive Principle:

Principle #10Preliminary action

4Ease of operation

If the terminal device reports MBMS frequency point without reception ability context, then the reporting is straightforward, but the network cannot perform correct service cell configuration

Engineering Contradiction:

Improvereporting operation simplicityVSAvoidservice cell configuration accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The reporting message merges three key elements: MBMS service identification information, MBMS frequency point information, and reception ability information. This combination provides the network with both the straightforward frequency point data and the contextual reception ability information needed for accurate service cell configuration, maintaining ease of operation while improving precision.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present disclosure discloses an MBMS service reception and capability transmission method and device. In this method, the terminal device may send the information of the MBMS service of interest of the terminal device or the information of the MBMS service, which is being received, to the network device and the MBMS service reception capability information of the terminal device via a message. If an MBMS frequency point corresponding to the MBMS service of interest of the terminal device or the MBMS frequency point corresponding to the MBMS service, which is being received, is within a reception capability scope of the terminal device in a current configuration, the message reported by the terminal device to the network device includes: the MBMS frequency point.
