As further shown in FIG. 17, node processor(s) 54-1 of wireless access node 22-1 may comprise message generator 60; plural path controller 162; and report handler 163. The message generator 60 serves to generate, e.g., plural path activation message 140 as described herein. The plural path controller 162 serves, e.g., to activate the plural paths, including first signaling data path SRB_f and second signaling data path SRB_s. The report handler 163 is configured to receive and process a report from child node 30 which is based on a notification representing a radio condition detected on one of the signaling data paths.
