5G VN Group VLAN Port Type Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G virtual network (VN) group data lacks port type information for VLAN ports, which hinders dynamic VLAN provisioning and management.
Innovation Solution
Incorporating VLAN port type indicators, such as access or trunk port types, into the 5G VN group configuration data, allowing for dynamic provisioning and management through enhanced UDM and UDR support, including VLAN ID lists and usage indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 5G VN group data is enhanced with VLAN configuration information including port type indicators, then dynamic VLAN provisioning capability is improved, but data structure complexity increases
Solution Approach 1:
The patent embeds VLAN configuration information (including port type indicators, VLAN ID lists, and usage indicators) within the existing 5G VN group data structure. This nested approach allows the enhanced data structure to carry additional VLAN management capabilities while maintaining compatibility with the original 5G system architecture, thus improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The enhanced VN group data structure serves multiple functions: it stores traditional 5G network information and simultaneously carries VLAN configuration information for dynamic provisioning. By making the data structure multi-functional, the patent enables a single data structure to support both 5G core network operations and VLAN management, reducing the need for separate complex systems.
2Adaptability or versatility
If VLAN configuration information is added to 5G system data structures, then network flexibility is improved, but information processing complexity increases
Solution Approach 1:
The patent pre-defines the structure and format of VLAN configuration information (including port type indicators, VLAN ID lists, and usage indicators) before integration into the 5G system. This preliminary structuring establishes clear processing rules and data formats in advance, which simplifies the information processing complexity when the data is actually processed, while still providing the necessary network flexibility.
3Measurement precision
If port type indicators are included in VLAN configuration, then VLAN management precision is improved, but data transmission overhead increases
Solution Approach 1:
The patent applies port type indicators selectively to specific VLAN configuration entries where needed, rather than uniformly adding the same level of detail to all data structures. This localized enhancement provides precise VLAN management information only where required for dynamic provisioning decisions, minimizing unnecessary data transmission overhead in other areas of the system.
Data Source
AI summary
Methods and apparatuses for control of virtual local area network (VLAN) are disclosed. According to an embodiment, a service consumer sends, to a service provider of a Fifth Generation System (5GS) that provides Ethernet bridging operations for User Equipments (UEs) acting as Ethernet access ports or Ethernet trunk ports, a request for providing configuration information related to a VLAN. The configuration information indicates a port type of at least one port related to the VLAN.
