UPF Internal Broadcast Interfaces for 5G Virtual Network Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G virtual network groups lack an effective solution for one-to-many communication, as existing technologies do not readily implement this functionality.
Innovation Solution
The implementation of at least two internal broadcast interfaces in a user plane function (UPF) allows for the transmission of broadcast data packets to all members or local members within a virtual network group, enabling one-to-many communication by using a target internal broadcast interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one-to-many communication is implemented in 5G virtual network group, then communication functionality is improved, but device complexity increases
Solution Approach 1:
The UPF is segmented into multiple internal broadcast interfaces, with each interface responsible for specific broadcast groups. This segmentation allows the system to handle one-to-many communication by dividing the complex broadcasting task into manageable interface-level operations, thereby improving communication functionality while controlling device complexity through modular design
Solution Approach 2:
The UPF is designed with multi-functional internal broadcast interfaces that can handle different broadcast groups and communication scenarios through a unified architecture. Each interface can serve multiple purposes including receiving broadcast packets, determining target groups, and forwarding to appropriate members, thus improving versatility without proportionally increasing overall device complexity
2Adaptability or versatility
If broadcast data packets are transmitted to all members in virtual network group, then communication coverage is improved, but network traffic increases
Solution Approach 1:
The patent implements local quality by allowing different internal broadcast interfaces to serve different broadcast groups with specific membership. Instead of uniformly broadcasting to all network members, each interface targets specific groups based on their characteristics and requirements, thereby improving communication coverage for relevant members while reducing unnecessary traffic to unrelated parts of the network
Solution Approach 2:
The internal broadcast interfaces act as intermediaries between the incoming broadcast packet and the final destination members. The interface determines the target broadcast group and selectively forwards packets only to relevant members within that group, thus achieving comprehensive coverage for targeted groups while minimizing overall network traffic by preventing unnecessary broadcasts to unrelated members

AI summary
A broadcast method is provided for a virtual network group. The method includes receiving a broadcast data packet transmitted by a member in a virtual network group, a target address of the broadcast data packet being a broadcast address, transmitting the broadcast data packet to a target internal broadcast interface in at least two internal broadcast interfaces, and transmitting the broadcast data packet to all members or all local members in the virtual network group by using the target internal broadcast interface.
