Abstract: A system, apparatus, method, and non-transitory computer readable medium for reducing and/or optimizing signaling messages between a radio access network (RAN) node and a core network based on an operation mode of the RAN node may include a core network server including: a memory storing computer readable instructions; and at least one processor configured to execute the computer readable instructions to establish a control plane connection with at least one radio access network (RAN) node, the at least one RAN node supporting at least a first connection mode and a second connection mode, determine a connection mode of the at least one RAN node, and restrict transmission of at least one signaling message to the at least one RAN node based on results of the determining the connection mode of the at least one RAN node.

Abstract: In accordance with an example embodiment of the present invention, a method comprising: sending, by a user equipment, a radio resource control (RRC) message, wherein the RRC message triggers transition of the user equipment from an RRC inactive state to an RRC connected state, wherein the RRC message is interpreted as a radio access network notification area (RNA) update; and receiving, by the user equipment, an RRC response message. The RRC message comprises a cause value indicating a combined RNA update with a non-access stratum (NAS) message.
