Session Management Network Element Terminal Communication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a method for managing and controlling the communication behavior of terminals in vertical industries, such as ports, hospitals, and factories, which can lead to security and stability issues.
Innovation Solution
A terminal management and control method is introduced, where a session management network element and a user plane network element obtain authorized communication information for terminals or terminal groups. When these terminals communicate with unauthorized devices, the network elements take management and control measures, such as packet discarding or reporting to a third-party device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal management and control measures are implemented to prevent unauthorized communication, then communication security and stability are improved, but device complexity and operational overhead increase
Solution Approach 1:
The network element obtains authorized communication information in advance before terminal communication occurs. This preliminary action establishes a whitelist of authorized devices beforehand, enabling the network to prevent unauthorized communication without requiring complex real-time analysis or decision-making during actual communication sessions.
Solution Approach 2:
The session management network element acts as an intermediary between terminals and the network. It receives authorized communication information from authentication network elements, processes this information, and uses it to control terminal communication behavior. This intermediary approach centralizes security management logic, reducing the complexity burden on individual terminals while maintaining strong security control.
2Stability of the object's composition
If authorized communication information is obtained and verified for each terminal communication, then communication stability is improved, but processing time and network overhead increase
Solution Approach 1:
The network element obtains and stores authorized communication information in advance during terminal authentication or session establishment. This preliminary preparation allows the network to perform simple lookup and verification operations during actual communication, rather than performing complex authentication and authorization analysis in real-time, thus reducing processing delay while maintaining communication stability.

AI summary
To manage and control a communication behavior of a terminal and ensure communication security of the terminal, this application provides a terminal management and control method, an apparatus, and a system. The method includes: A session management network element obtains authorized communication information of a first terminal or a terminal group, where the authorized communication information includes information about a device with which the first terminal or the terminal group is allowed to communicate; when the first terminal or a second terminal in the terminal group communicates with a device not listed in the authorized communication information, the session management network element learns that a management and control measure needs to be taken on communication of the first terminal or the second terminal; and the session management network element takes the management and control measure.
