Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current MMS network architectures face challenges in scaling to accommodate 'spiky' A2P/P2A traffic patterns, leading to network delays and increased operational management complexity, especially during busy hours when traffic surges occur.

Innovation Solution

Implementing a communication system with a dedicated MMSC for application-specific traffic that isolates A2P traffic from P2P traffic, reducing the impact of surges and simplifying operational management by using a gateway device to route traffic through a limited number of connections, thereby reducing VASP operational complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single MMSC handles all MMS traffic (P2P and A2P), then device complexity is reduced, but network reliability deteriorates during traffic surges

Engineering Contradiction:

ImproveMMSC architecture complexityVSAvoidnetwork performance during traffic surges

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the MMSC functionality into separate entities: a first MMSC for handling P2P traffic and a second MMSC for handling A2P traffic. This segmentation isolates the 'spiky' A2P traffic patterns from P2P traffic, preventing traffic surges from degrading overall network performance and maintaining reliable service during peak times.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If A2P traffic is mixed with P2P traffic in the same MMSC, then operational management is simplified, but network delay increases during busy hours

Engineering Contradiction:

Improveoperational management complexityVSAvoidnetwork delay during traffic surges

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

By separating A2P and P2P traffic into different MMSCs, the patent eliminates the network delay problem that occurs when spiky A2P traffic mixes with P2P traffic. The dedicated second MMSC ensures that A2P traffic surges do not cause delays for other traffic types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a gateway device as an intermediary between the second MMSC and VASPs. This gateway concentrates signaling and manages connections to multiple VASPs, simplifying operational management while maintaining traffic isolation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple connections to VASPs are maintained in each MMSC, then adaptability improves, but device complexity increases

Engineering Contradiction:

ImproveVASP connection flexibilityVSAvoidconnection management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the VASP connection management function into a dedicated gateway device associated with the second MMSC. This gateway handles all connections to multiple VASPs, allowing the MMSC to maintain adaptability to various VASPs while reducing the complexity at the MMSC level through functional consolidation.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A system provides Multimedia Messaging Service (MMS) to mobile stations through a wireless communication network for person-to-person traffic and traffic to/from an application. The network may include a plurality of Multimedia Messaging Service Centers (MMSCs) coupled to the wireless communication network for MMS communication between two mobile stations, and between a mobile station and an application during call origination mode operations. A second MMSC coupled to the wireless communication network, provides MMS communications between mobile stations and one or more applications during call termination mode operations. In a mobile origination mode operation, the second MMSC concentrates signaling from the first MMSCs and forwards received MMS data, and in a mobile termination mode operations, the second MMSC delivers MMS data to a destination mobile station without forwarding the MMS data to one of the first MMSCs.
