Roaming Content Filtering via Home Network Rule Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content screening technologies for roaming users in communication networks lead to network processing resource waste and longer processing times due to the need for sequential screening by both home and visited networks, increasing the likelihood of single-point failures and negatively impacting user experience.
Innovation Solution
A method where the visited network obtains and converts the screening rules from the home network, allowing for simultaneous screening of contents by both networks, thereby reducing processing time and resource consumption, and enhancing user experience by minimizing the impact of single-point failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential content screening is performed by both home network and visited network for roaming users, then content security coverage is improved, but network processing time and resource consumption increase
Solution Approach 1:
The home network performs content screening in advance before the roaming user accesses content in the visited network. The screened content is then forwarded to the visited network, which can directly deliver it to the user without performing redundant screening. This preliminary action ensures security requirements are met while avoiding duplicate processing time.
Solution Approach 2:
The content screening process is divided into two segments: home network screening and visited network delivery. The home network handles the screening function while the visited network handles the delivery function, allowing parallel processing and reducing overall time loss by eliminating sequential dependency.
2Reliability
If sequential content screening is performed by both home network and visited network for roaming users, then content security coverage is improved, but network processing resource consumption increases
Solution Approach 1:
The home network performs content screening in advance before the roaming user accesses content in the visited network. The screened content is then forwarded to the visited network, which can directly deliver it to the user without performing redundant screening. This preliminary action ensures security requirements are met while avoiding duplicate processing time.
Solution Approach 2:
The home network creates a copy of the screened content and forwards it to the visited network. The visited network then uses this copy for delivery without needing to perform its own screening, thereby reducing resource consumption while maintaining security coverage.
3Reliability
If sequential content screening is performed by both home network and visited network for roaming users, then comprehensive rule application is improved, but system complexity and failure risk increase
Solution Approach 1:
The content screening function is extracted from the visited network and centralized in the home network for roaming users. The home network applies all necessary screening rules (both home network rules and visited network rules) in one location, then delivers the screened content to the visited network for straightforward delivery, reducing system complexity and failure risk.
4Reliability
If sequential content screening is performed by both home network and visited network for roaming users, then comprehensive rule application is improved, but processing time increases
Solution Approach 1:
The home network performs content screening in advance before the roaming user accesses content in the visited network. The screened content is then forwarded to the visited network, which can directly deliver it to the user without performing redundant screening. This preliminary action ensures security requirements are met while avoiding duplicate processing time.
Solution Approach 2:
The content delivery process maintains continuity by having the home network continuously screen and forward content to the visited network, which then continuously delivers it to users without interruption or redundant processing steps, thereby improving overall productivity while maintaining comprehensive rule application.

AI summary
A method for filtering communication content of roaming user is provided, including: the second network of the roaming user acquires the rules for filtering received or transmitted contents from the first network of the roaming user, filters the received or transmitted contents based on the filtration rules. A content filtration server, a system for filtering the communication content of the roaming user and home network content filtration server and visited content filtration server are also provided. The problems of wasting of network resource and time cost when processing the received or transmitted contents in the visited network are solved.
