1. In a personal communication system (PCS) comprising at least one base station manager (BSM) for downloading softwares to processors of a plurality of PCS devices, a method for managing software, comprising the steps of:

  • (a) setting a processor type to each processor, where each processor type is a string of bits including a plurality of bits equal to 0 and one bit equal to 1, and similar processor types have an identical string of bits and dissimilar processor types differ in that bit positions equal to 1 do not overlap;

    (b) setting a software type to each software, where each software type is a string of bits including a plurality of bits equal to 0 and at least one bit equal to 1, and each software type corresponds to at least one processor type by having a bit equal to 1 located in the same position as the bit equal to 1 in the processor type;

    (c) determining a processor type of a processor generating a loading request; and

    (d) downloading a software to the processor when a result of an AND operation between the bit position equal to 1 of the processor type and the corresponding bit position of a software type of the software equals 1.
