5GLAN Group Communication Rule Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G local area network (5GLAN) service faces a significant increase in configuration workload due to changes in the number of terminal members, as each terminal addition or removal requires updating forwarding rules across all members, leading to inefficiencies in group communication.
Innovation Solution
A group communications method and system where a group management function network element manages forwarding rules, updating only the rules associated with the terminal member accessing the network, while keeping rules for other members unchanged, thereby reducing the configuration workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing packet forwarding solution is applied to group communication, then group communication functionality is achieved, but configuration workload increases significantly when terminal members are added or removed
Solution Approach 1:
The patent segments the forwarding rule configuration into two parts: (1) a group-level forwarding rule that applies to all members of a 5GLAN group, and (2) individual terminal-specific configurations. When a terminal is added or removed, only the group-level forwarding rule needs to be updated, not the configurations for all individual terminals. This segmentation reduces the configuration workload from O(n) to O(1) where n is the number of terminal members.
Solution Approach 2:
The patent creates a universal forwarding rule at the group level that can be applied to multiple terminals simultaneously. This group-level forwarding rule serves as a template that automatically applies to all current and future members of the 5GLAN group, eliminating the need to create individual forwarding rules for each terminal. This multi-functionality approach reduces repeated configuration operations.
2Reliability
If forwarding rules are updated for all members when a terminal joins or leaves, then communication consistency is maintained, but time consumption increases
Solution Approach 1:
The patent separates forwarding rule management into group-level and terminal-level segments. The group-level forwarding rule ensures communication consistency for all members, while terminal-level configurations handle individual connectivity. When a terminal joins or leaves, only the group-level rule needs updating, maintaining consistency without requiring time-consuming updates to all individual terminal configurations.
Solution Approach 2:
The patent pre-establishes a group-level forwarding rule template that defines the forwarding behavior for the entire 5GLAN group. This preliminary configuration serves as a foundation that automatically applies to any terminal joining the group, eliminating the need for time-consuming individual configurations and ensuring consistent communication behavior from the moment a terminal joins.

AI summary
A group communications method and system, and a device are provided. The method includes: when a first terminal initiates access to a local area network group, obtaining, by a group management function network element, an identifier of a first user plane network element to be accessed by the first terminal, context information of the local area network group, and a first session port identifier; creating, for the local area network group, a rule group applied to a first session port, and creating or updating, for the local area network group based on the context information, a local area network group forwarding action rule (FAR) applied to the first user plane network element; and sending a first message to a session management network element, for configuring the rule group on the first session port, and configuring the local area network group FAR on the first user plane network element.
