Dynamic IP Anchor Placement for Low Latency Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network deployments statically place network functions, which limits the ability to dynamically allocate resources based on user device and application requirements, such as low latency needs for applications like autonomous vehicle-to-vehicle communications, leading to suboptimal network performance.
Innovation Solution
An anchor point platform dynamically places Internet Protocol (IP) anchor points based on user devices and applications by determining whether an application requires low latency or best effort services, designating appropriate network devices as anchor points, and dynamically allocating control plane and user plane functions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network functions are statically placed in existing network deployments, then network deployment simplicity is maintained, but network performance and latency optimization for specific applications cannot be achieved
Solution Approach 1:
The patent implements dynamic placement of IP anchor points and network functions based on real-time application requirements and user device locations. The system transitions from static network function deployment to dynamic deployment, allowing network functions to be relocated according to service demands, thereby improving network performance without permanently increasing deployment complexity
Solution Approach 2:
The system changes the operational parameters of network functions by adjusting their placement locations based on application type (low latency vs. best effort) and user device characteristics. This parameter adjustment enables the same network infrastructure to serve different performance requirements without requiring entirely separate deployments
2Loss of time
If network functions are placed closer to user devices to reduce latency, then latency for low-latency applications is improved, but computing resources are consumed
Solution Approach 1:
The patent applies different network function placement strategies to different applications based on their specific requirements. Low-latency applications receive network functions placed closer to user devices, while best-effort applications use standard placement. This localized optimization reduces overall computing resource consumption by avoiding unnecessary replication of network functions for all applications
Solution Approach 2:
The system dynamically adjusts network function placement based on real-time application requirements rather than maintaining fixed proximity for all services. This dynamic approach allows computing resources to be allocated efficiently, placing functions closer to users only when latency-critical applications are detected
3Ease of operation
If manual placement of network functions is performed, then precise control over function location is achieved, but automation and efficiency are reduced
Solution Approach 1:
The system implements automated feedback mechanisms that monitor application requirements, user device locations, and network conditions to automatically determine optimal network function placement. This feedback loop replaces manual placement while maintaining precise control through algorithmic decision-making based on real-time network state
Solution Approach 2:
The network system automatically performs network function placement without requiring manual intervention. The system serves itself by autonomously detecting application requirements and configuring network functions accordingly, thereby achieving both automation and operational precision simultaneously

AI summary
A device determines whether an application, utilized by a user device and associated with a network, is a low latency application or a best effort application. The device designates a first network device or a second network device as a designated network device to be an IP anchor point for the application based on a set of rules. The first network device is designated as the designated network device when the application is the low latency application, or the second network device is designated as the designated network device when the application is the best effort application. The device provides, to the user device, information informing the user device that the designated network device is to be the IP anchor point for the application, and provides, to the network, information instructing the network to utilize the designated network device as the IP anchor point for the application.
