MNO ASN Routing in Cloud-Native 5G Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud-native 5G wireless networks, mobile network operators (MNOs) face the challenge of interconnecting with other communication service providers (CSPs) where the CSPs require the use of the MNO's autonomous system number (ASN) instead of the cloud computing service provider's ASN.
Innovation Solution
The MNO causes the ASN of the MNO to be used for network traffic from its network functions (NFs) to the other CSP network by routing the traffic through a virtual router controlled by the MNO within the public cloud, ensuring the MNO's ASN is utilized instead of the cloud computing service provider's ASN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cloud computing service provider's ASN is used for network traffic, then the network infrastructure complexity is reduced, but the ability to interconnect with other CSP networks is compromised
Solution Approach 1:
The patent introduces a BGP speaker component that acts as an intermediary between the cloud-native network functions and the external CSP networks. This BGP speaker translates and announces the MNO's ASN to external networks, enabling interconnection while the internal cloud infrastructure continues to use the cloud provider's ASN. The intermediary resolves the contradiction by decoupling the internal networking from external networking requirements.
2Quantity of substance
If the MNO deploys network functions in a public cloud, then hardware investment is reduced, but control over ASN usage is lost
Solution Approach 1:
The patent extracts the ASN control function from the cloud provider's infrastructure and places it within the MNO's controlled environment. By deploying a BGP speaker that the MNO controls within the cloud network, the MNO can maintain its own ASN and routing policies while still utilizing the cloud provider's physical infrastructure. This extraction of the control plane from the data plane resolves the contradiction between reduced hardware investment and maintained operational control.

AI summary
Example embodiments are directed towards systems and methods for a fifth generation (5G) cloud-native wireless telecommunication network operated by a mobile network operator (MNO) implemented on a public cloud of a cloud computing service provider. Such a method may include the MNO operating telecommunication network functions (NFs) of the 5G wireless telecommunication network running within the public cloud. An indication may be received that one or more of the NFs of the 5G wireless telecommunication network running within the public cloud has a requirement to connect to another communication service provider (CSP) network different than the 5G cloud-native wireless telecommunication network operated by the MNO. Based on the indication, the system causes an autonomous system number (ASN) of the MNO to be used for network traffic from the one or more NFs to the other CSP network instead of an ASN of the cloud computing service providers.
