A system and method for beam switching by a User Terminal (UT). The method includes initiating a beam switch between an old beam and a new beam when the UT is disposed in an overlap area of the old beam and the new beam; duplicating over the new beam, at a Network Access Point (NAP), user traffic to the UT; and assigning a Time Division Multiplex Access (TDMA) allocation for the UT on the new beam, prior to an arrival of the UT on the new beam, where the user traffic traversing a satellite network remains uninterrupted during the beam switch and the NAP redirects user traffic for the UT via the old beam to the new beam.
