Methods and systems for mobility management in non-terrestrial networks are disclosed. In one embodiment, a method performed by a first communication node, includes: during a first time period, communicating with a non-terrestrial communication node utilizing a first communication link, wherein the non-terrestrial communication node provides at least one geographic cell in which a user equipment device (UE) is present during the first time period; during a second time period, communicating with a second communication node utilizing a second communication link, wherein a third communication link is established between the non-terrestrial communication node and the second communication node and the first communication link is no longer utilized during the second time period; and determining to maintain the first communication node as an anchor node for communications between a core network and the UE during both the first and second time periods.
