Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single address information sending method is used, then the system is simple, but multiple user plane address information cannot be sent to the core network
Solution Approach 1:
The address information is segmented into multiple distinct components: first address information (including first transport layer address and first GTP-TEID) and second address information (including second transport layer address and second GTP-TEID). Each segment corresponds to a specific user plane, allowing the system to send address information for multiple user planes separately while maintaining clear organization and management of each address component.
Solution Approach 2:
The solution extends the traditional single address sending mechanism by adding another dimension of address information. Instead of a single address tuple, the system now handles multiple address tuples (first and second address information) with distinct transport layer addresses and GTP-TEIDs, enabling multi-user plane support while building upon the existing signaling framework.
2Productivity
If transmission capacity is increased to Tbps level, then higher rate requirements are met, but deployment costs and network complexity increase substantially
Solution Approach 1:
The user plane functionality is segmented into multiple independent user planes (first user plane and second user plane), each with its own address information (transport layer address and GTP-TEID). This segmentation allows the network to handle high transmission capacity requirements by distributing traffic across multiple user planes, thereby meeting Tbps-level rate requirements while maintaining manageable network complexity through modular organization.
Solution Approach 2:
The address sending mechanism is enhanced to support multiple user planes universally. The same signaling interface can carry both first address information and second address information, allowing a single interface to serve multiple functions (multiple user planes) without requiring separate dedicated interfaces for each user plane, thus controlling deployment complexity.
3Loss of information
If multiple user plane address information needs to be sent, then complete address coverage is achieved, but existing signaling interfaces are insufficient
Solution Approach 1:
The solution merges the sending of first address information and second address information through the same signaling interface between the RAN node and core network node. By combining multiple address information transmissions into a unified signaling mechanism, the system achieves complete address coverage for multiple user planes without requiring separate dedicated interfaces for each user plane, thereby avoiding excessive interface complexity.
Solution Approach 2:
The signaling interface is enhanced to serve multiple functions: it can carry both first address information (first transport layer address and first GTP-TEID) and second address information (second transport layer address and second GTP-TEID). This multi-functional interface design ensures complete address information delivery for multiple user planes while maintaining interface simplicity and reusability.
