Connection Control Device for Multi-SGW UE Path Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network environment where a user equipment (UE) can be connected to multiple serving gateways (SGWs), conventional connection control methods may lead to inconsistency in managing the connected status of the UE, affecting packet transmission and reception.
Innovation Solution
A connection control method and device that receive path establishment requests from multiple communication control devices, process the establishment of communication paths for all involved devices, and update information on the establishment status of these paths to ensure consistency across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional connection control method is applied to a network environment where a UE can be connected to multiple SGWs, then the UE can access the network through multiple gateways, but inconsistency may occur in management of the connected status of the UE within the network
Solution Approach 1:
The connection control device receives establishment result information from communication control devices and updates the stored establishment status based on this feedback. This feedback mechanism ensures that the centralised information accurately reflects the actual connection status across multiple SGWs, preventing inconsistency.
Solution Approach 2:
The connection control device acts as an intermediary between multiple communication control devices and the UE. It centralizes the management of connection status information, receiving requests from any SGW and coordinating the establishment process across all involved devices, thereby ensuring consistent status management throughout the network.
2Productivity
If path establishment requests are processed independently for each communication control device, then processing is simpler and faster, but inconsistency in establishment status information may occur across devices
Solution Approach 1:
The connection control device merges the management of establishment status information from multiple communication control devices into a single centralized location. Instead of each device maintaining separate status information that could become inconsistent, all establishment status data is consolidated and updated in one place, ensuring uniformity across the network.
Solution Approach 2:
The system implements a feedback loop where the connection control device receives establishment result information from communication control devices and uses this feedback to update the stored establishment status. This ensures that the centralized information remains synchronized with the actual state of communication paths across all devices.

AI summary
A connection control method is implemented by a communication system including a UE, two or more SGWs, and an MME for performing processing related to establishment and release of communication paths between the two or more SGWs and the UE. The connection control method includes a request reception in which the MME receives an establishment request of a communication path associated with the UE from one SGW, a path establishment starting processing related to establishment of communication paths between the UE and all SGWs, and an information updating in which the MME updates information related to an establishment status of the communication path stored in a storage unit on the basis of a result of establishing the communication path.
