Radio Access Control Device Bearer Control Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, the combined architecture of Mobile Switching Center (MSC) and Base Station Controller (BSC) devices limits the ability to optimize service and radio advantages, as it increases system maintenance complexity and costs, and fails to effectively separate bearer from control functions, leading to inefficient IP packet routing and resource wastage.
Innovation Solution
Implementing a radio access control device with a media gateway control application layer that processes signaling messages and routes traffic data based on IP addresses, eliminating the need for a separate media gateway and allowing direct routing between BSCs, thereby reducing IP packet exchanges and maintaining the separation of bearer from control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If MSC and BSC devices are combined into one device, then device complexity is reduced and cost is lowered, but the ability to optimize service and radio advantages is limited, and system maintenance complexity increases
Solution Approach 1:
The patent segments the combined MSC-BSC device into functionally independent modules: control plane functions (MSCe, BSC) and user plane functions (MGW, MRFP). This segmentation allows each module to be independently optimized, maintained, and upgraded, resolving the contradiction by enabling service optimization while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent extracts the media gateway functions (MGW and MRFP) as separate deployable entities from the control device. This extraction enables independent optimization of control and user plane functions, allowing service and radio advantages to be optimized without increasing overall system complexity, as the extracted components can be deployed flexibly across different physical platforms.
2Device complexity
If MSC and BSC devices are combined into one device, then initial device structure is simplified, but system maintenance complexity and costs increase
Solution Approach 1:
The patent segments the system into control plane (MSCe, BSC) and user plane (MGW, MRFP) components that can be independently maintained. This segmentation reduces maintenance complexity by allowing targeted updates and repairs of specific modules without affecting the entire system, while the initial simplified structure is preserved through the logical integration of these segmented components.
Solution Approach 2:
The patent introduces dynamic deployability where MGW and MRFP can be flexibly allocated and reconfigured based on service requirements. This dynamic architecture simplifies maintenance by enabling hot-swapping and incremental upgrades of user plane functions without disrupting control plane operations, reducing both initial complexity and maintenance burden.
3Reliability
If separate media gateway is used, then bearer from control separation is achieved, but IP packet routing requires more switches and wastes system resources
Solution Approach 1:
The patent merges the control device (MSCe/BSC) with user plane processing capabilities through the deployable MGW and MRFP components. This merging maintains bearer-control separation by keeping control and user plane functions logically distinct while physically integrated, eliminating the need for separate media gateway devices and reducing IP packet switching overhead, thus preventing system resource wastage.
Solution Approach 2:
The patent creates a universal control device that can simultaneously perform MSCe, BSC, MGW, and MRFP functions through dynamic configuration. This multi-functionality enables bearer-control separation while eliminating redundant dedicated media gateway devices, reducing the number of IP packet switches required and optimizing system resource utilization through consolidated multi-functional architecture.
