12. A control method executed by a base station apparatus, comprising:
acquiring information of a tracking area identifier (TAI) of a neighbor cell adjacent to a cell formed by the base station apparatus and a TAI list that comprises a plurality of TAIs belonging to a same tracking area to which the cell formed by the base station apparatus belongs, wherein the plurality of TAIs indicate tracking areas that can provide an identical network slice;
providing, when performing registration of a position of a terminal apparatus, the terminal apparatus with TAIs belonging to the TAI list; and
transmitting, after providing the TAIs belonging to the TAI list to the terminal apparatus, a broadcast signal including the TAI of the neighbor cell and cell identifier of the neighbor cell.
