name: VPLMN
full_form: Visited PLMN
context: In this use case the subscriber is roaming in a VPLMN with user plane traffic routed to the HPLMN. The subscriberâs access to the VPLMN is any of the following: a) a trusted non-3GPP access with S2a interface to the VPLMN S-GW or to the HPLMN P-GW; b) a non-trusted non-3GPP access with a Wn* interface to the VPLMN ePDG, and an S2b interface from the VPLMN ePDG to the VPLMN S-GW or to the HPLMN P-GW; c) a connection over the S2c interface from the UE to the VPLMN S-GW or to the HPLMN P-GW over trusted or non-trusted non-3GPP access or 3GPP access. The network architecture for this use case is specified in clause 4.2.2 in TS 23.402 [4], and also depicted in clause 4.2.2 in the present document. Editorâs note: Other possible roaming scenarios are currently studied in SA2.
description: A Visited Public Land Mobile Network (VPLMN) is a network that a subscriber is visiting or roaming on, as opposed to their Home PLMN (HPLMN). The VPLMN provides the subscriber with access to telecommunications services while they are outside of their home network.
explanation: The context describes a use case where a subscriber is roaming in a VPLMN and accessing various types of networks and interfaces. This indicates that VPLMN refers to a specific type of network, which justifies its classification as a Network entity.
