Network slicing is a key enabler of 5G's promise to deliver a wide range of services, from enhanced mobile broadband (eMBB) to ultra-reliable low-latency communications (URLLC) and massive machine-type communications (mMTC). By allowing multiple networks to coexist on the same physical infrastructure, network slicing provides several benefits: By allowing multiple networks to coexist on the

: VoLTE and 5G VoNR networks run voice traffic completely over SIP. During global roaming, an operator must route SIP traffic over external internetwork connections (IPX/GRX), dramatically scaling the potential entry points for a malicious payload. Architectural Pillars of GSMA FS.38
