The new radio resource control inactive state has become the main status of user equipments (UEs) in 5G networks, because of its low power consumption and energy saving features. To deal with the massive signaling overhead in 5G networks, in this paper, we introduce a UE assisted dynamic RAN notification area (RNA) configuration scheme to effectively reducing the paging and the RNA update overhead of inactive UEs. Especially, UEs are divided into two categories, namely, the speed-priority type and the rate-priority type based on their communication rate, mobility, as well as the location. Accordingly, we further extensively investigate the dynamic RNA configuration update process in both the theoretical and the practical manner. The performance of proposed schemes is evaluated via simulations and the results demonstrate the effectiveness and the efficiency in achieving the design goals, which could achieve a considerable performance improvement with respect to schemes in literatures.
