NBIFOM Routing Rule Consistency via Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication technologies, when a terminal receives a routing rule from a network in the network-initiated NBIFOM mode, it often cannot enforce the rule, leading to incorrect transmission of traffic flows.
Innovation Solution
A method where a terminal sends an NBIFOM routing rule request to an intermediate network device, receives and acknowledges routing rules from the device, and communicates this acknowledgement to the gateway device to ensure consistency and correct transmission of traffic flows by identifying and rejecting non-enforceable routing rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network sends routing rules to the terminal in the network-initiated NBIFOM mode, then the network can control traffic flow routing, but the terminal cannot enforce the routing rules leading to incorrect transmission
Solution Approach 1:
The terminal sends routing rule acknowledgement information back to the network to indicate whether it can enforce the received routing rules. This feedback mechanism allows the network to know if the terminal can properly enforce the routing rules, enabling reliable routing rule transmission while maintaining network control.
Solution Approach 2:
The terminal performs a check before enforcing routing rules to determine whether it can enforce them. This preliminary action prevents incorrect transmission by ensuring the terminal is capable of enforcing the routing rules before actually using them for traffic flow routing.
2Reliability
If the terminal acknowledges routing rules to ensure consistency with the gateway device, then correct traffic flow transmission is achieved, but additional communication overhead is introduced
Solution Approach 1:
The terminal sends routing rule acknowledgement information containing identifiers of acknowledged and rejected routing rules to the intermediate network device, which forwards it to the gateway device. This feedback ensures consistency between the terminal and gateway device for correct traffic flow transmission while keeping the overhead minimal through efficient information exchange.

AI summary
Embodiments of the present invention provide a method and a system for routing rule transmission, and a device. The method includes: sending, by a terminal, an NBIFOM routing rule request to a gateway device through an intermediate network device; sending, by the gateway device, at least one routing rule to the terminal through the intermediate network device according to the NBIFOM routing rule request; sending, by the terminal, routing rule acknowledgement indication information to the gateway device through the intermediate network device according to the at least one received routing rule; and determining, by the gateway device according to the routing rule acknowledgement indication information, a routing rule rejected by the terminal in the at least one routing rule, so that the gateway device transmits a traffic flow by using a routing rule other than the routing rule rejected by the terminal in the at least one routing rule. This ensures consistency of routing rules used by the gateway device and the terminal, and ensures correct transmission of the traffic flow.
