1. A method, comprising:
storing, at a first network node, a user equipment-specific uplink small data transmission context for a user equipment in a non-connected radio resource control state, wherein the first network node previously had initiated, without anchor relocation from an anchor network node, a small data transmission procedure via the first network node or a second network node, and wherein the stored user equipment-specific uplink small data transmission context comprises user equipment-specific radio link control context for small data transmission, functional split (F1) uplink tunnel endpoint identifiers associated with centralized unit-user plane of the anchor network node of the user equipment's data radio bearer, and user equipment identifier.
