This disclosure relates generally to wireless communications and, more particularly, to systems and methods for maintaining signal and data connections from a mobile base station portion relative to a fixed network portion. In one embodiment, a method performed by a communication node gateway, includes: receiving a signal from a mobile communication node portion at a first dynamic port during a first duration of time; directing the signal from the first dynamic port to a static port associated with transport network layer information during the first duration of time; receiving the signal at a second dynamic port during a second duration of time after the first duration of time; and directing the signal from the second dynamic port to the static port during the second duration of time by using the transport network layer information.
