Embodiments include methods for a second radio access network (RAN) node configured to support positioning of user equipment (UEs) in the RAN. Such methods include receiving, from a UE, a request to resume the UE's connection to the RAN that is currently suspended. The request includes a first indication that UE had an ongoing positioning procedure with a first RAN node before the UE's connection to the RAN was suspended, and/or a second indication that the UE reported positioning measurements to the first RAN node before the UE's connection was suspended. Such methods include retrieving, from the first RAN node, positioning measurements made by the first RAN node during the positioning procedure and continuing the positioning procedure for the UE while the UE is connected to the RAN via the second RAN node. Other embodiments include complementary methods for the UE, the first RAN node, and a positioning node.
