Physical Service Communication Proxy Domains for Overlapping IP Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks face challenges in efficiently managing interconnections between service communication proxy (SCP) domains due to the lack of clear mapping between Internet Protocol (IP) addresses or Fully Qualified Domain Names (FQDNs) and SCP domains, particularly in complex network environments with overlapping IP address spaces.
Innovation Solution
Enhancing SCP profiles registered in the Network Repository Function (NRF) to include specific mappings of IP addresses or FQDNs to SCP domains, allowing SCPs to identify and communicate with appropriate domains based on their own domain connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP address spaces are overlapped across multiple physical networks to improve network flexibility and resource utilization, then network adaptability is improved, but message routing accuracy deteriorates due to inability to distinguish source domains
Solution Approach 1:
The patent introduces Service Communication Proxy (SCP) domains as intermediary layers between physical networks and application services. Each SCP domain acts as a mediator that maintains the mapping relationship between IP addresses/FQDNs and their corresponding network domains, enabling accurate message routing even when IP address spaces overlap across multiple physical networks. The SCP domain profile stored in NRF serves as the intermediary data structure that resolves the routing ambiguity.
2Measurement precision
If SCP profiles are enhanced to include detailed mappings of IP addresses and FQDNs to SCP domains to improve routing accuracy, then message routing precision is improved, but profile complexity and storage requirements worsen
Solution Approach 1:
The patent segments the network information management into hierarchical layers: physical networks are abstracted into SCP domains, and each SCP domain is assigned a unique identifier. The SCP domain profile in NRF stores mappings at the domain level rather than individual IP address level, segmenting the complexity management. This allows routing decisions to be made at the domain level while maintaining the ability to map multiple IP addresses and FQDNs to each domain through structured profile data.
3Adaptability or versatility
If multiple physical networks with overlapping IP spaces are interconnected to expand network coverage and connectivity, then network versatility is improved, but communication reliability deteriorates due to domain identification errors
Solution Approach 1:
The patent introduces an additional dimension of abstraction by mapping IP addresses and FQDNs not directly to physical networks but to SCP domains as an intermediate layer. This dimensional transformation allows the system to handle overlapping IP address spaces from multiple physical networks by resolving them through the SCP domain dimension stored in NRF, thereby maintaining communication reliability while supporting diverse network interconnections.

AI summary
Systems, methods, apparatuses, and computer program products for implementing a physical service communication proxy domain A method may include interconnecting a first network element with one or more service communication proxy domains, each associated with one or several internet protocol addresses or fully qualified domain names used for the interconnection. The method may also include registering the first network element with a network repository function by sending a service operation to the network repository function. Further, the service operation may include profile information of the first network element. In addition, the profile information may include one or more service communication proxy domains, each associated with one or several internet protocol addresses or fully qualified domain names.
