The multiple registration schemes (MRSs) proposed here are classified into 3 cases by combining five registration schemes which are power up registration scheme (PURS), power down registration scheme (PDRS), zone based registration scheme (ZBRS), distance based registration scheme (DBRS), and implicit registration scheme (IRS) as follows: the first is MRS1 which covers PURS, PDRS, and ZBRS; the second is MRS2 which covers PURS, PDRS, and DBRS; the third is MRS3 which covers PURS, PDRS, IRS, and DBRS. The three proposed schemes are compared each other by analyzing their combined signaling traffic of paging and registration with considering various parameters of a mobile station behavior (unencumbered call duration, power up and down rate, velocity, etc.). Also, we derive allowable location areas from which the optimal location area is obtained. Numerical results show that MRS3 yields better performance than ZBRS, DBRS, MRS1, and MRS2 in most cases of a mobile station behavior, and it has an advantage of distributing the load of signaling traffic into every cell, which is important in personal communication system.
