MME Traffic Control via SCEF Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic control methods in mobile networks, particularly for IoT terminals, do not consider the traffic characteristics between application servers and communication terminals, leading to potential service failures and increased network resource consumption.
Innovation Solution
A method involving a mobility management entity (MME) and a base station that receives communication pattern parameters from a service capability exposure function (SCEF) via a home subscriber server, using these parameters to control transmission resources for uplink and downlink data, thereby optimizing traffic control and reducing resource consumption.

Engineering Contradiction Analysis
1Loss of energy
If the SCEF performs independent traffic control to prevent large data inflow into the core network, then resource consumption in the core network is reduced, but the application server may perform retransmission causing further traffic increase
Solution Approach 1:
The patent introduces the MME as an intermediary between the SCEF and the base station. The MME receives communication pattern parameters from the SCEF, stores them in the HSS, and then provides them to the base station. This intermediary role allows the system to implement traffic control while avoiding direct rejection mechanisms that would trigger retransmissions, thereby reducing core network resource consumption without causing traffic increases from retransmission attempts.
Solution Approach 2:
The patent implements preliminary action by pre-configuring communication pattern parameters (such as data amounts, time periods, and transmission intervals) in the HSS before actual data transmission occurs. The base station retrieves these pre-stored parameters to control uplink and downlink traffic. This preliminary configuration enables proactive traffic management that prevents excessive data transmission before it can congest the core network, while still allowing legitimate traffic to pass through without triggering retransmissions.
2Loss of energy
If the communication terminal performs independent traffic control based on SCEF information, then data inflow into the core network is prevented, but the application service may not function normally
Solution Approach 1:
The MME acts as an intermediary that reconciles the conflict between traffic control and service functionality. Instead of relying on the communication terminal to independently block traffic (which would disrupt service), the MME uses the pre-stored communication pattern parameters to intelligently control traffic at the network level. This allows the terminal to maintain normal service operations while the MME ensures that traffic patterns align with network capacity and service requirements.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting transmission resources based on communication pattern parameters such as data amounts, time periods, and transmission intervals. These parameters are stored in the HSS and retrieved by the base station to control uplink and downlink traffic. By changing these parameters rather than simply blocking traffic, the system maintains service functionality while achieving effective traffic control and preventing core network congestion.
3Loss of energy
If traffic control is implemented without considering application traffic characteristics, then network resource consumption is reduced, but service failures occur
Solution Approach 1:
The patent applies parameter changes by incorporating application-specific traffic characteristics into the communication pattern parameters stored in the HSS. These parameters include data amounts, time periods, and transmission intervals that are tailored to specific application requirements. The base station uses these customized parameters to control uplink and downlink traffic, ensuring that traffic control measures align with application characteristics. This approach reduces network resource consumption while preventing service failures by maintaining appropriate traffic patterns for each application.

AI summary
An object is to provide a control device which can control, in consideration of a traffic characteristic of an application operating between an application server and a communication terminal, traffic or a data amount transferred on a core network. A control device (10) according to the present example embodiment includes: a communication unit (12) configured to receive, via a service control device (20) which authenticates an application server (30) providing a service for a communication terminal (50), information relating to a transmittable data amount determined in the application server (30); and a control unit (11) configured to execute, by using the information relating to the transmittable data amount, traffic control on data transmitted from the communication terminal (50).
