Base Station Direct Data Transfer Bypassing Core Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular network techniques fail to adequately reduce the load on the core network and manage data transmission and reception efficiently, as they often require data to pass through the access gateway, leading to increased service delays and communication quality issues.
Innovation Solution
An apparatus and method where a base station or network device controls data transmission directly between terminal devices without going through the gateway, using a table to determine eligible routes and transmitting related information to the gateway or specific nodes for management purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through the access gateway in the core network, then network management and control are maintained, but the load on the core network increases and service delay increases
Solution Approach 1:
The patent segments data transmission into two paths: control plane traffic continues through the access gateway for management, while user plane traffic is routed directly between base stations. This segmentation allows management capabilities to be preserved while reducing core network load and service delay for data transmission.
Solution Approach 2:
The patent introduces a direct peer-to-peer communication path between base stations as an intermediary route, bypassing the access gateway for user data transmission. This intermediary path reduces the load on the core network while the access gateway retains management functions.
2Productivity
If data is transmitted directly between base stations without going through the access gateway, then the load on the core network is reduced and service delay is decreased, but network management becomes difficult
Solution Approach 1:
The patent divides network functions into control plane (managed through access gateway) and user plane (direct base station communication). This segmentation enables high-speed data transmission while maintaining centralized management capabilities for network operations.
Solution Approach 2:
The patent implements feedback mechanisms where base stations report transmission status and data information to the access gateway, allowing the gateway to maintain management oversight despite direct transmission paths. This feedback loop ensures network management remains effective while benefiting from reduced core network load.
3Reliability
If all data transmission routes are managed through the access gateway, then network control is centralized, but the complexity of the network architecture increases
Solution Approach 1:
The patent segments the network architecture into control plane functions (centralized at access gateway) and user plane functions (distributed at base stations). This reduces architectural complexity by allowing base stations to handle user data independently while the gateway manages control functions.
Solution Approach 2:
The patent extracts user plane data transmission functions from the access gateway and places them directly at base stations. This extraction simplifies the overall network architecture by removing unnecessary routing through the gateway while maintaining centralized control for management functions.

AI summary
[Object] To enable management related to transmission and reception of data to be performed while reducing the load on the core network. [Solution] Provided is an apparatus including: an acquiring unit configured to acquire data destined for a second terminal device which is transmitted from a first terminal device to a base station of a cellular system; and a control unit configured to control transmission of the data in a manner that the data is transferred from the first terminal device to the second terminal device without going through a gateway configured to perform data transfer in the cellular system. The control unit controls transmission of information related to the data to the gateway or a specific node, and the specific node is a node configured to receive, from the gateway, information related to another data transferred via the gateway.
