Terminal Management Device Group Load Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the evolved packet core (EPC) network of current mobile phone communication services, the redistribution of processing load between mobility management entities (MMEs) leads to a significant amount of information being transmitted and received, causing increased infrastructure costs and potential call losses due to processing delays, which existing techniques are insufficient to address.
Innovation Solution
A mobile communication control system that includes a terminal management device capable of generating group information for mobile terminal devices based on specific criteria, allowing for the redistribution of processing loads among MMEs by associating devices into groups, thereby reducing the amount of information needed for load redistribution and minimizing processing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If load redistribution is performed between MMEs by transmitting information with mobile terminal device as a unit, then load balancing is achieved, but the amount of information transmitted and received becomes enormous
Solution Approach 1:
The patent groups multiple mobile terminal devices into a single group managed by one MME. When load redistribution is needed, the entire group is transferred as a unit rather than individual devices. This merging approach dramatically reduces the amount of information that needs to be transmitted during load balancing operations, as the MME only needs to exchange group identification information rather than detailed subscriber data for each device.
Solution Approach 2:
The patent segments the managed devices into distinct groups that can be independently transferred between MMEs. Each group is identified by a group ID that is stored and managed by the MME. This segmentation allows for efficient load redistribution by transferring entire groups as atomic units, reducing the complexity and volume of information exchange required during MME failover or load balancing scenarios.
2Productivity
If high degree of processing capability is provided in MME, S-GW, and eNodeB to handle enormous information amount, then load redistribution can be performed, but construction cost of communication infrastructure rises
Solution Approach 1:
By merging multiple terminal devices into a single manageable group, the patent reduces the overall information processing requirements of the MME, S-GW, and eNodeB. Instead of handling detailed information for each individual terminal during load redistribution, the system only needs to manage group-level information. This significantly lowers the processing capability requirements and consequently reduces the construction cost of the communication infrastructure.
3Productivity
If delay occurs in processing of redistributing load between MMEs due to enormous information amount, then call loss may occur
Solution Approach 1:
The patent combines multiple terminal devices into groups that can be transferred as single units between MMEs. This merging approach drastically reduces the amount of information that needs to be processed during load redistribution, enabling faster transfer operations. The reduced information volume allows the system to complete load redistribution quickly, minimizing processing delays and preventing call losses that would otherwise occur during extended transfer periods.
4Productivity
If existing techniques (PTL 1 and PTL 2) are used for load redistribution, then some processing optimization is achieved, but they are insufficient to solve the problem of enormous information amount
Solution Approach 1:
The patent introduces a novel segmentation approach by grouping terminal devices into manageable units with unique group IDs. This segmentation strategy fundamentally differs from existing techniques by creating hierarchical management structures. The group-based segmentation enables the system to handle load redistribution at an aggregated level, making the solution adaptable to various network scales and configurations, thereby overcoming the limitations of existing techniques that cannot effectively manage large numbers of terminals.
