Dynamic Anchor Network Component Switching for Wireless Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in providing seamless and efficient data session continuity for mobile devices as they move, leading to increased latency and reduced performance due to the fixed anchoring of mobile data sessions at packet data network gateways, which hinders the delivery of local content and edge computing applications.
Innovation Solution
A communication management component (CMC) dynamically manages connections between communication devices and network components, allowing for the switching of anchor and serving network components based on location and communication conditions to optimize data routing and reduce latency, ensuring that data sessions follow the user even when they move across different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mobile data sessions are anchored at fixed packet data network gateways, then network management is simplified, but latency increases and performance deteriorates as devices move
Solution Approach 1:
The patent implements dynamic anchor network component selection where the anchor PDU session gateway is no longer fixed but changes based on device location and network conditions. The system dynamically determines which anchor PDU session gateway to use by evaluating communication conditions between the wireless device and potential anchor gateways, allowing the network to adapt to mobile device movements and maintain optimal performance.
2Device complexity
If anchor network components are fixed, then network architecture is simplified, but local content delivery and edge computing performance are hindered
Solution Approach 1:
The patent enables local content delivery by selecting anchor PDU session gateways that are geographically or network-proximity close to the wireless device. This local quality approach ensures that data sessions are anchored at network components that can provide low-latency access to local content and edge computing services, rather than forcing all traffic through distant fixed gateways.
3Ease of operation
If data sessions are anchored at fixed gateways, then connection management is easier, but seamless mobility and application continuity are compromised
Solution Approach 1:
The system continuously monitors communication conditions between the wireless device and anchor PDU session gateways, using this feedback to determine when to switch anchors. This feedback mechanism ensures that application continuity is maintained by proactively switching to a better anchor gateway before performance degradation occurs, rather than relying on fixed pre-configured anchors.

AI summary
Connecting user equipment (UE) to an application can be managed based on UE movement and location. During data session between UE and application, a communication management component (CMC) associated with anchor network component (ANC) or serving network component (SNC) determines UE location, and connects UE to the ANC and SNC, which enables access of the application via a data network associated with ANC. As UE moves, CMC tracks UE movement and communication conditions. If, when UE is at second location, a communication condition breaches threshold level, CMC determines whether interruption of the data session is permitted. If not, CMC determines whether there is a local SNC in proximity to second location. If there is, CMC can switch UE from SNC to local SNC, which can access local application content via local data network associated with application. If interruption permitted, UE deactivates and reactivates to connect to local ANC.
