Application Driven Network Segmentation for Signaling Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face congestion issues due to the mixing of different service types, leading to service unavailability and inefficient data channel utilization, especially with the increasing number of intelligent terminals generating frequent, short network signaling.
Innovation Solution
The implementation of an application-driven network with a three-layer structure, comprising a core controller layer, network controller layer, and access point layer, where control channels are separated by application type, allowing for dedicated networks to manage and optimize signaling and data transmission independently, reducing congestion and improving network utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If services of various network types are mixed in one network, then network resource sharing is improved, but signaling congestion causes service unavailability and network breakdown
Solution Approach 1:
The patent segments the network into multiple virtual networks (e.g., voice network, data network, machine-to-machine network) that are logically separated but share the same physical infrastructure. Each virtual network handles specific service types independently, preventing signaling congestion from affecting other services while maintaining resource sharing capabilities.
2Adaptability or versatility
If a large quantity of terminals are connected to the network, then network coverage is improved, but network signaling resources are consumed
Solution Approach 1:
The patent divides the network into multiple virtual networks that can independently manage signaling resources. By segmenting the network traffic into different virtual networks based on service type, the system can handle a large quantity of terminals more efficiently, reducing the overall signaling load on each individual virtual network while maintaining comprehensive coverage.
3Device complexity
If control signaling channels are not distinguished, then network simplicity is maintained, but signaling congestion affects multiple network types
Solution Approach 1:
The patent implements logical segmentation of control signaling channels into separate virtual networks while maintaining a unified physical network structure. This approach provides signaling isolation to prevent congestion propagation without requiring physically separate networks, thus balancing simplicity and reliability.
4Reliability
If application driven networks are established for various applications, then signaling separation is improved, but network complexity increases
Solution Approach 1:
The patent implements a universal virtual network framework that can accommodate multiple application-specific virtual networks within a single unified architecture. This multi-functional approach allows different applications (voice, data, machine-to-machine) to have dedicated virtual networks while sharing the same physical infrastructure and management mechanisms, reducing overall complexity compared to fully separate networks.

AI summary
Embodiments of the present invention provide a communications system of an application driven network, so that control channels in the communications system are classified and separated according to application types. The communications system includes: a core controller, a network controller cluster, and an access point cluster. The core controller is configured to allocate at least one network controller in the network controller cluster and at least one access point in the access point cluster to form an application driven network, where the core controller is configured to: form an application control channel and manage the at least one access point, and the at least one access point is configured to form an application data channel. An access point in the access point cluster is configured to establish a communication channel with a terminal device, so that the terminal device accesses the control channel and the application data channel in the application driven network.
