Solution Overview

Problem

Current integrated access systems face challenges in decoupling radio frequency and baseband resources, leading to low reliability and maintainability due to shared management systems, which hinders efficient service activation and upgrade processes.

Innovation Solution

The implementation of an integrated access system with separate baseband units (BBUs) connected to distinct base station network management subsystems allows for independent configuration and management of radio frequency and baseband resources, enabling decoupling and improving reliability and maintainability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a same base station network management subsystem is used to manage both radio frequency resource and baseband resource, then device complexity is reduced, but reliability and maintainability deteriorate

Engineering Contradiction:
Improvemanagement subsystem structureVSAvoidsystem reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the management subsystem into separate radio frequency management and baseband management functions. The BBU is separated from the network management subsystem, with independent management paths for radio frequency resources (through RHUB) and baseband resources (through separate management subsystem), enabling independent configuration and maintenance of each function without affecting the other.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a same base station network management subsystem is used to manage both radio frequency resource and baseband resource, then device complexity is reduced, but maintainability deteriorates

Engineering Contradiction:
Improvemanagement subsystem structureVSAvoidsystem maintainability
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The management subsystem is segmented into independent radio frequency management and baseband management modules. This allows operators to maintain and upgrade each function independently - radio frequency resources can be managed through the RHUB while baseband resources are managed through the separate management subsystem, facilitating easier repair and maintenance operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The BBU is extracted from the integrated management subsystem, allowing it to be managed independently. The separation enables specific management functions to be extracted and optimized - radio frequency management through RHUB and baseband management through dedicated management subsystems, improving overall maintainability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If radio frequency resource and baseband resource are managed together, then device complexity is reduced, but service activation and upgrade process deteriorates

Engineering Contradiction:
Improveresource management structureVSAvoidservice activation and upgrade efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The resource management structure is segmented into independent radio frequency management and baseband management paths. Service activation and upgrade operations can be performed independently on each resource type - radio frequency resources can be activated or upgraded through the RHUB while baseband resources are managed through the separate management subsystem, significantly improving service activation and upgrade efficiency.

Inventive Principle:
Principle #1Segmentation

AI summary

Example configuration methods and apparatus are described. In one example method, a first baseband unit (BBU) updates a first line rate, and sends a data frame to the second BBU at an updated first line rate after each update. The first BBU receives a data frame that is sent by the second BBU at an updated second line rate after each time the second BBU updates a second line rate. When the first line rate is equal to the second line rate, the first BBU sends networking relationship information of the first BBU to the second BBU at the first line rate, and receives networking relationship information of the second BBU that is sent by the second BBU at the second line rate. The first BBU establishes a bidirectional upper-layer communication channel with the second BBU based on a communication address of the second BBU allocated by the first BBU.
