1. A radio access network (RAN) node, comprising:
a memory having computer readable instructions stored thereon; and
processing circuitry configured to execute the computer readable instructions to cause the RAN node to perform the following operations:
collect network handover information associated with at least one first user equipment (UE) device traveling between at least one cell pair, the at least one cell pair including a cell served by the RAN node and at least one neighboring cell of the RAN node;
transmit positioning service requests for each of the at least one first UE device to an network device;
receive position information corresponding to each of the at least one first UE device from a location management function (LMF) network device in response to the transmitted positioning service requests;
collect the received position information as historical position information for the at least one first UE device;
determine whether to update a mobility policy associated with the RAN node based on the collected network handover information and a desired threshold condition;
perform a first mobility policy update procedure for the RAN node based on results of the determination, wherein the performing comprises:
generating mapping information based on the historical position information and the collected network handover information, wherein generating the mapping information comprises:
determining boundaries for a plurality of boundary areas based on handover failure type information associated with each of the plurality of boundary areas included in the network handover information;
updating the mobility configuration parameters for each of the plurality of boundary areas associated with the at least one cell pair, wherein the updated mobility configuration parameters includes an updated cell individual offset (CIO) value and an updated time-to-trigger (TTT) value;
transmitting the determined mapping information to the LMF network device, and
transmitting the updated mobility configuration parameters to the RAN node;
transmit the historical position information to a centralized entity (CE) network device for each of the at least one first UE device, the historical position information including the network handover information corresponding to the at least one first UE device; and
receive the updated mobility configuration parameters from the CE network device;
receive current location information corresponding to at least one second UE device traveling between the at least one cell pair from the LMF network device in response to the performed first mobility policy update procedure, the current location information including a boundary area identifier of a current boundary area corresponding to the current location of the at least one second UE device; and
assign updated mobility configuration parameters to the at least one second UE device based on the boundary area identifier, the received current location information of the at least one second UE device, and the mapping information associated with the cell served by the RAN node, the mapping information including a plurality of boundary areas associated with the at least one cell pair.
