Solution Overview

Problem

The existing network architecture in LTE and LTE-A standards is static, leading to inefficient use of network resources due to the same protocol stack being used for diverse services like high-bandwidth video and small-packet M2M services, resulting in suboptimal data transmission and processing.

Innovation Solution

A multiflow transmission method and device that divides data streams into sub-streams based on control instructions, allowing different base stations to process and offload data streams, thereby improving network resource utilization and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a same protocol stack is used to support all services in a static network morphology, then network architecture simplicity is maintained, but network resource utilization is reduced

Engineering Contradiction:
Improvenetwork architecture simplicityVSAvoidnetwork resource utilization
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments the data stream into multiple sub-streams that can be processed through different protocol stacks simultaneously. This allows the network to handle diverse services (video, M2M, etc.) with appropriate protocol treatments without requiring complete architectural redesign, thus improving resource utilization while maintaining manageable complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic protocol stack selection where the protocol configuration can change based on service type and network conditions. This dynamic adaptation allows the same physical infrastructure to efficiently support multiple service types with different requirements, resolving the contradiction between architectural simplicity and resource utilization

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If a same protocol stack is used for diverse services like video and M2M, then protocol implementation simplicity is maintained, but data transmission efficiency is reduced

Engineering Contradiction:
Improveprotocol implementation simplicityVSAvoiddata transmission efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The data stream is divided into sub-streams that can be routed through different protocol stack configurations optimized for specific service types. This segmentation allows video traffic to use protocols optimized for high bandwidth while M2M traffic uses protocols optimized for small packets, improving overall transmission efficiency without requiring complete reimplementation of protocols

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different protocol stack configurations are applied locally to different sub-streams based on their specific requirements. Each sub-stream receives the appropriate protocol treatment for its service type, achieving optimal transmission efficiency for each while maintaining overall system simplicity through standardized segmentation and routing mechanisms

Inventive Principle:
Principle #3Local quality

AI summary

The present invention provides a multiflow transmission method and device, where the method includes: dividing, by a first base station, a data stream into at least two sub-data streams according to a first control instruction, where the first control instruction is generated by a controller, and is used to instruct the first base station to offload the data stream, and the data stream is a data stream processed by at least one protocol module of the first base station; and continuing, by the first base station, to process one sub-data stream of the at least two sub-data streams according to the first control instruction, and separately sending another sub-data stream of the at least two sub-data streams to a corresponding second base station, so that the second base station continues to process the another sub-data stream. According to the foregoing method, network resource utilization is improved.
