1. A method performed by a gateway of a communication node, comprising:
receiving a first signal from a distributed unit of a base station at a first dynamic port of the gateway during a first duration of time, wherein the distributed unit of the base station is located within a satellite or an unmanned aerial vehicle (UAV);
directing the first signal from the first dynamic port to a static port of the gateway based on transport network layer information during the first duration of time, wherein the static port is connected to a fixed port of a fixed network portion;
receiving a second signal from the distributed unit of the base station at a second dynamic port of the gateway during a second duration of time after the first duration of time; and
directing the second signal from the second dynamic port to the static port during the second duration of time based on the transport network layer information, wherein the distributed unit of the base station and the fixed network portion maintain radio network layer application protocol connection instances while the distributed unit of the base station is in motion, wherein the radio network layer application protocol connection instances include one or both of: a next generation application protocol interface (NGAP) and an F1 application protocol interface (F1AP),
wherein the first dynamic port, the second dynamic port, and the static port are within the gateway of the communication node.
