Service Linkage Control via DPI Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication technologies face challenges in service linkage identification and control when control and data channels are separated, as only control or data information can be inspected and determined independently, making individual identification of services on either channel meaningless.
Innovation Solution
A service linkage control system and method that employs a Deep Packet Inspection (DPI) identification module, a DPI identification device information collection database, a linkage information control center, and a linkage strategy management module to generate and implement control strategies for service linkage identification and control, using predefined templates and rules to associate and control services across separated channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control channel and data channel are separated for network service implementation, then network service flexibility and scalability are improved, but service linkage identification and control capability deteriorates
Solution Approach 1:
The patent introduces a linkage control center as an intermediary component that collects control channel information and data channel information separately, then correlates them to achieve service linkage identification. This mediator enables the system to maintain channel separation while recovering the linkage control capability through centralized information correlation.
Solution Approach 2:
The patent segments the service control function into separate control channel processing and data channel processing components. The control channel is handled by a control plane entity while the data channel is handled by a data plane entity, with linkage information managed by a separate linkage control center. This segmentation allows independent optimization of control and data paths while maintaining linkage awareness.
2Ease of operation
If only control channel message is inspected, then control information processing is simplified, but data channel service identification capability deteriorates
Solution Approach 1:
The patent merges control channel information collection and data channel information collection into a unified linkage control framework. The linkage control center aggregates control plane messages and data plane messages, correlating them to achieve comprehensive service identification. This merging enables precise data channel service identification while maintaining simplified control processing through structured information aggregation.
3Ease of operation
If only data channel message is inspected, then data channel processing is simplified, but control channel service identification capability deteriorates
Solution Approach 1:
The linkage control center serves as an intermediary that collects data channel information and correlates it with control channel information. This mediator enables the system to maintain simplified data channel processing while achieving comprehensive control channel service identification through information correlation at the linkage control center.
4Device complexity
If control channel and data channel are completely separated, then network architecture simplicity is improved, but service linkage control capability deteriorates
Solution Approach 1:
The linkage control center acts as a lightweight intermediary layer that maintains network architecture simplicity while enabling service linkage control. It collects control plane and data plane information separately, then correlates them to achieve linkage awareness without requiring intimate integration of control and data channels, thus preserving architectural simplicity.
Solution Approach 2:
The patent adds a new dimensional layer - the linkage control center - that operates independently from both control and data channels. This additional dimension enables service linkage control by correlating information from control and data channels without requiring modification of the fundamental separated architecture, thus maintaining simplicity while achieving control capability.

AI summary
A service linkage control system and method are disclosed for implementing service linkage identification and control for separated control channel and data channel in the communication system. The method includes that: a linkage strategy management module (102) sends a first service template of the service needing linkage identification to a Deep Packet Inspection (DPI) identification module (101) to identify the service needing linkage identification, and sends after classification a service identification result and linkage related information to a linkage strategy management module (102) via a DPI identification device information collection database (104) and a linkage information control center (105); the linkage strategy management module (102) generates a service control strategy according to the received service identification result and a predetermined control rule, and issues the control strategy to a DPI control module (103); and the DPI control module (103) receives and implements the control strategy.
