TL;DR
This paper proposes the MS-Router concept, enabling next-generation mobile systems to support IP routing for behind-UE subnetworks by modeling the mobile system as an IP router with dynamic topology learning.
Contribution
It introduces the MS-Router architecture, allowing mobile systems to act as IP routers with routing protocol capabilities for supporting behind-UE subnetworks.
Findings
MS-Router models mobile system as an IP router per User Plane
Enables dynamic topology learning of behind-UE subnetworks
Supports optimal routing configuration for IP subnetworks
Abstract
The upcoming generation of mobile telecommunication systems is expected to support new use cases, where the mobile network serves one or more IP subnetworks located behind the User Equipment (UEs). This would create new challenges for the mobile system to efficiently serve such behind-UE subnetworks, as the latter are commonly not visible to the mobile system. In 3GPP, there have been works on Time-Sensitive Networking (TSN) and Deterministic Networking (DetNet), where the 5G System (5GS) is considered as a bridge or a DetNet node. In order to efficiently serve behind-UE IP subnetworks, we foresee the need for a further generalization where the mobile system (5GS and beyond) acts as a set of IP routers with more generic capabilities. In this article, we introduce the concept of Mobile System Router (MS-Router) which aims to provide a reference architectural design to enable the support…
