Virtual Network Nodes for Paging Message Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing communication traffic due to smartphones and emerging M2M and IoT services leads to a surge in requests for calling multiple terminals in a mobile network, causing a significant increase in C-plane processing load on the Mobility Management Entity (MME) when multiple terminals respond with control signals simultaneously.
Innovation Solution
A control device and communication system that utilize virtual network nodes running on virtual machines to process control signals, allowing the MME to request virtual network nodes to transmit paging messages with delayed transmission times, thereby dispersing the timing of control signal receptions and reducing the load on the MME.

1Productivity
If the MME transmits paging messages to multiple terminals simultaneously in response to a call request, then the terminals can be called efficiently, but the C-plane processing load on the MME increases significantly when multiple terminals respond with control signals simultaneously
Solution Approach 1:
The invention segments the MME's paging processing function by introducing virtual network nodes (VNNs) that can be distributed across multiple physical hosts. Each VNN handles paging messages for specific terminals, dividing the centralized processing load into distributed segments. This allows the MME to maintain efficient paging transmission while distributing the control signal processing load across multiple VNN instances, thereby reducing the processing burden on any single MME instance.
Solution Approach 2:
The invention adds a spatial dimension to paging processing by deploying VNNs across multiple physical hosts and network locations. Instead of all paging processing occurring in a single centralized MME, the processing is distributed across multiple dimensional spaces (different hosts, different network nodes), allowing parallel processing of control signals from multiple terminals without overwhelming a single processing point.
2Speed
If multiple terminals simultaneously transmit control signals to the MME in response to receiving paging messages, then the terminals can establish sessions quickly, but the MME cannot process the control signals within a short period due to increased load
Solution Approach 1:
By segmenting the control signal processing function across multiple virtual network nodes distributed on different hosts, the system can parallelize the processing of simultaneous control signals from multiple terminals. Each VNN can independently process control signals received from terminals it pages, enabling faster aggregate processing capacity while maintaining quick session establishment for individual terminals.
Solution Approach 2:
The virtual network nodes act as intermediaries between the MME and the terminals. When the MME transmits paging messages, the VNNs receive and process the subsequent control signals from terminals, mediating the communication flow. This intermediary layer distributes and manages the control signal processing load, preventing bottlenecks at the MME while maintaining fast session establishment through efficient parallel processing.

AI summary
The objective of the invention is to suppress increases in a C-Plane processing load on a mobile network side even if requests to call a plurality of terminals in the mobile network are generated within a short period of time. In some embodiments, a terminal transmits a control signal for connecting to a network in response to receiving a paging message. In some embodiments, a plurality of virtual network nodes, each capable of running on a virtual machine, have a function of processing the control signal from the terminal. Also disclosed is a control device which, in response to receiving a packet addressed to the terminal, requests at least one of the plurality of virtual network nodes to transmit a paging message addressed to the terminal.
