MNO ASN Routing for Cloud-Native 5G Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud-native 5G wireless networks operated by mobile network operators (MNOs) face challenges in interconnecting with other communication service provider (CSP) networks, as the latter often 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 use of its own ASN for network traffic to other CSP networks by routing traffic through virtual routers controlled by the MNO within the public cloud, bypassing the cloud computing service provider's ASN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cloud-native 5G wireless networks use the cloud computing service provider's ASN for network traffic, then the network can operate within the public cloud infrastructure, but the network cannot interconnect with other CSP networks that require the MNO's own ASN
Solution Approach 1:
The patent introduces a border router as an intermediary device between the cloud-native 5G network and external CSP networks. This border router is configured with both the cloud computing service provider's ASN and the MNO's own ASN, allowing it to translate and forward packets between different ASN domains. The border router acts as a mediator that enables interconnection compatibility without requiring the entire cloud-native network to change its ASN configuration, thus resolving the contradiction between using cloud infrastructure ASN and maintaining MNO identity for external interconnection.
2Ease of operation
If the MNO uses the cloud computing service provider's ASN, then the deployment flexibility and agility of cloud-native architecture is maximized, but the MNO loses control over ASN usage for interconnection with other CSP networks
Solution Approach 1:
The patent segments the network into two distinct functional zones: the cloud-native 5G core network that operates with the cloud computing service provider's ASN for maximum deployment agility, and the border router interface that handles MNO's ASN for external interconnection. This segmentation allows each part of the network to operate with appropriate ASN assignments - the cloud-native portion maintains deployment flexibility while the border router portion ensures interconnection compatibility with other CSP networks.
Solution Approach 2:
The patent applies local quality by assigning different ASN characteristics to different parts of the network infrastructure. The cloud-native 5G network functions operate with the cloud provider's ASN locally, maintaining deployment agility, while the border router is configured with dual ASN capability to provide MNO identity locally at the interconnection point. This localized ASN assignment strategy allows the network to optimize for deployment flexibility in the cloud portion while ensuring interconnection flexibility at the network boundary.
3Ease of manufacture
If the MNO deploys network functions within the public cloud of a cloud computing service provider, then infrastructure costs and operational complexity are reduced, but the MNO cannot satisfy CSP network requirements for using the MNO's ASN
Solution Approach 1:
The border router serves as a mediator that enables reliable interconnection between the cloud-deployed 5G network and external CSP networks. By configuring the border router with both the cloud provider's ASN and the MNO's ASN, the system maintains the simplicity of cloud deployment while ensuring reliable interconnection through ASN translation and packet forwarding at the border router, thus resolving the contradiction between deployment ease and interconnection reliability.

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.
