7. A method comprising:
sending, to a location management function or enhanced-serving mobile location center, a location request to determine a location of a terminal, the location request comprising an indication of an area and information for determining an accuracy requirement for the location of the terminal;
receiving, from the location management function or enhanced-serving mobile location center, an approximate current location of the terminal and an indication of whether the terminal is inside of the area;
using at least the indication to determine whether to restrict network access to the terminal;
determining, based on the approximate current location of the terminal and a predicted or observed mobility of the terminal, how frequently to request the location of the terminal from the location management function or enhanced-serving mobile location center;
sending, based on the determining, to the location management function or enhanced-serving mobile location center, another location request to determine the location of the terminal;
receiving, from the location management function or enhanced-serving mobile location center, another approximate current location of the terminal and another indication of whether the terminal is inside of the area;
using at least the another indication to determine whether to restrict network access to the terminal; and
again determining, after the receiving the another approximate current location and the another indication, based on the another approximate current location of the terminal and the predicted or observed mobility of the terminal, how frequently to request the location of the terminal from the location management function or enhanced-serving mobile location center.
