Solution Overview

Problem

Existing signaling methods for multimedia broadcast multicast service (MBMS) are not applicable to generic access networks (GAN) due to bandwidth constraints, making it difficult to support MBMS over GAN.

Innovation Solution

A method and system that establish an MBMS bearer by delivering an MBMS notification with a generic access network cell description, directing an electronic device to a GAN cell, and utilizing channels like GERAN, UTRAN, LTE, and Wimax for MBMS signaling and application procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing signaling methods for MBMS are used in GAN, then the service can be supported in traditional networks, but the bandwidth constraints of GAN make these signaling methods inapplicable

Engineering Contradiction:

ImproveMBMS service supportVSAvoidbandwidth

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent changes the signaling parameters by delivering MBMS notifications including GAN cell description information through existing channels, and modifies the bearer establishment procedure to be compatible with GAN bandwidth constraints while maintaining MBMS service functionality

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary signaling mechanism where MBMS notifications are delivered through existing channels to convey GAN cell description, serving as a mediator between the MBMS service requirements and the GAN network capabilities

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If MBMS bearer is established with full cell description, then service quality is improved, but signaling overhead increases bandwidth consumption

Engineering Contradiction:

Improveservice deliveryVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential GAN cell description information needed for MBMS service delivery from the full cell description, reducing signaling overhead while maintaining sufficient service quality through selective information delivery

Inventive Principle:

Principle #2Taking out (Extraction)
