Base Station Virtual MME Selection for Traffic Offloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network congestion relief techniques are limited to terminals capable of using multiple radio systems, and cannot effectively offload communication traffic in environments where such access is not possible, thereby failing to reduce congestion in all scenarios.
Innovation Solution
A base station and communication system that select a Mobility Management Entity (MME) based on terminal information, allowing the selection of a virtual MME operating through a virtual machine to manage network traffic, enabling traffic offloading independent of the terminal's radio environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network switching technique is used to ease congestion, then communication traffic can be offloaded, but the technique is limited to terminals capable of accessing multiple radio systems and cannot work in locations where such access is not possible
Solution Approach 1:
The patent introduces a virtual MME as an intermediary component that enables traffic offloading without requiring terminal capability changes. The virtual MME acts as a mediator between the base station and the core network, allowing the network to perform traffic routing decisions independently of terminal radio capabilities. This resolves the contradiction by providing a network-side solution that works universally regardless of terminal type or location.
Solution Approach 2:
The patent shifts the traffic offloading mechanism from the terminal dimension (requiring multi-radio capability) to the network dimension (virtual MME selection). By moving the decision-making and traffic routing functions to the network side through virtualization, the system achieves offloading effectiveness without being constrained by terminal capabilities or geographic location.
2Productivity
If a virtual MME is selected based on terminal information, then traffic offloading can be performed independently of terminal radio environment, but the system complexity increases due to virtual machine management
Solution Approach 1:
The virtual MME is designed as a universal component that can serve multiple functions: it handles mobility management, performs traffic routing decisions, and enables traffic offloading. By consolidating these functions into a single virtualized entity that can be selected and instantiated as needed, the patent reduces operational complexity while maintaining enhanced traffic offloading capability.
Solution Approach 2:
The system dynamically selects virtual MMEs based on changing network conditions and terminal information. By changing the selection parameters and routing decisions in real-time, the system achieves effective traffic offloading without requiring complex permanent reconfiguration. The virtual MME infrastructure provides flexible parameter-based control that simplifies deployment and operation.

AI summary
A technique that can enhance the effectiveness of traffic offloading is provided. A base station of the present invention includes: a first means for selecting an MME (Mobility Management Entity), based on information included in a message sent from a terminal; and a second means for sending a connection request sent from the terminal to the selected MME, wherein the first means is able to select a virtual MME that operates a function of the MME through a virtual machine, based on the information included in the message.
