NGxC Network Service Orchestration via VNF Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G LTE wireless communication networks face limitations in bandwidth, network congestion, latency, and inability to support diverse IoT devices due to dependency on limited bandwidth and lack of native support for Circuit-Switched core networks, which affects service scalability and Quality of Service (QoS).
Innovation Solution
The implementation of a next-generation mobile core (NGxC) network that performs orchestration of services by determining user entitlement and network capability, dynamically provisioning resources, and creating network nodes as needed to ensure efficient delivery of services, utilizing Software Defined Networking (SDN) principles and standardized interfaces for Quality of Service (QoS) management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If 4G LTE network shares bandwidth among increased number of devices, then network coverage is improved, but network throughput is reduced
Solution Approach 1:
The patent segments the core network into multiple Virtual Network Functions (VNFs) that can be independently instantiated and distributed across different physical hosts. This segmentation allows the network to handle multiple service flows simultaneously through parallel processing, thereby maintaining throughput while expanding coverage to serve more devices.
Solution Approach 2:
The patent introduces a virtualization dimension by deploying VNFs as software instances that can be dynamically allocated across the network infrastructure. This adds a logical layer of organization that enables multiple service instances to coexist and operate in parallel, effectively increasing throughput capacity without proportionally increasing physical bandwidth requirements.
2Productivity
If 4G LTE network increases bandwidth capacity, then network throughput is improved, but network cost increases
Solution Approach 1:
The patent creates universal Virtual Network Function instances that can serve multiple service types and traffic flows. A single VNF instance can be dynamically allocated to handle different service requirements (e.g., voice, data, IoT) based on demand, allowing the network to provide high throughput for multiple services without provisioning dedicated bandwidth for each service type.
Solution Approach 2:
The patent implements dynamic resource allocation where VNF instances can be created, migrated, and scaled in real-time based on network conditions and service demands. This dynamic approach allows the network to optimize throughput performance by allocating computational resources to where they are most needed, rather than provisioning fixed bandwidth capacity in advance.
3Loss of time
If 4G LTE network reduces latency, then service responsiveness is improved, but network complexity increases
Solution Approach 1:
The patent pre-positions VNF instances in strategic network locations and maintains ready-to-activate service chains. By having service functions pre-configured and staged in advance, the network can rapidly activate services with minimal processing delay when traffic arrives, reducing latency without requiring complex real-time decision-making algorithms.
4Adaptability or versatility
If 4G LTE network supports diverse IoT devices, then service versatility is improved, but QoS management becomes difficult
Solution Approach 1:
The patent applies local quality by allowing different VNF instances to be configured with service-specific parameters and policies tailored to their particular service function. Each VNF can implement QoS handling appropriate to its service type (e.g., strict QoS for voice, best-effort for data), enabling diverse IoT device support while keeping QoS management localized and manageable at each service boundary.
Data Source
AI summary
A method and system for performing orchestration of services in a next generation mobile core (NGxC) is disclosed. The method includes receiving a request from a user for accessing a service from a plurality of services supported by the NGxC network. Upon receipt of the request, the method includes determining at least a type of requested service and a feasibility of delivering the requested service at least based on an entitlement of the user and a capability of a network node for delivering the requested service. The method further includes performing an orchestration of services and one or more resources of the NGxC network for delivering the requested service, based on the determined feasibility.
