Apparatuses, systems, methods, and non-transitory computer readable media for reducing signaling messages between a ran node and a core network

A radio access network (RAN) node supporting at least one of a standalone architecture (SA) connection mode or a non-standalone architecture (NSA) connection mode, comprising:

• a memory storing computer readable instructions;
• and
• at least one processor configured to execute the computer readable instructions to,
• set a connection mode of the RAN node, the connection mode being at least the SA connection mode or the NSA connection mode;
• and
• transmit at least one control plane connection request message to at least one core network server, the at least one control plane connection request message including an indication of the connection mode of the RAN node,
• the transmitted at least one control plane connection request message causing the at least one core network server to selectively restrict transmission of at least one signaling message based on the indication of the connection mode.

A method of operating at least one core network server, the method comprising:

• establishing, using at least one processor, a control plane connection with at least one radio access network (RAN) node, the at least one RAN node supporting at least one of a standalone architecture (SA) connection mode or a non-standalone architecture (NSA) connection mode;
• determining, using the at least one processor, a connection mode of the at least one RAN node based on an indication from the at least one RAN node;
• setting, using the at least one processor, a signaling message configuration value corresponding to the at least one RAN node based on results of the determining the connection mode of the at least one RAN node;
• and
• determining, using the at least one processor, whether to transmit at least one signaling message based on the signaling message configuration value for the at least one RAN node.
