S. Park et al., LOCALITY BASED LOCATION TRACKING USING VIRTUALLY HIERARCHICAL LINK INPERSONAL COMMUNICATIONS SERVICES, IEICE transactions on communications, E81B(9), 1998, pp. 1779-1781
The proposed method tracks the user location in a hierarchically distr
ibuted fashion. Call patterns in personal communications services (PCS
) have the locality. The virtually hierarchical link (VHL) is used to
support the call locality and makes the fast call set up possible. The
locality consideration effectively reduces the query traffic compared
with non-locality consideration.
