Abstract

A method for managing software in a code division multiple access (CDMA) base station system of a personal communication system (PCS) includes the step of setting a processor type to each processor in the base station system, where each processor type is a string of bits including a plurality of bits equal to 0 and one bit equal to 1. Similar processor types have an identical string of bits and dissimilar processor types differ in that bit positions equal to 1 do not overlap. A software type is set to each software in the base station system, 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. Each software corresponds to at least one processor by having a bit equal to 1 located in the same position as the bit equal to 1 in the processor type string. Software is downloaded to a download requesting processor when the result of an AND operation between the bit position of the processor type equal to 1 and the corresponding bit position of the software type equals 1.

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.

2. The method of claim 1, wherein a newly added processor has its processor type set according to step (a).

3. The method of claim 1, wherein a newly added software has its software type set according to step (b).

4. The method of claim 2, wherein the software type of a new software corresponding to the newly added processor is set to the processor type of the newly added processor.

5. The method of claim 2, wherein the software type of a previously downloaded software corresponding to the newly added processor is set to the sum of an OR logic function which ORs the software type of the previously downloaded software and the processor type of the newly added processor.

6. The method of claim 1, further comprising the step of deleting a type of a processor to be deleted.

7. The method of claim 1, further comprising the step of deleting a type of a software to be deleted.

8. The method of claim 1, wherein the processor types and the software types both have the same number of bits.

9. The method of claim 1, wherein the software type of a newly added software which does not correspond to a newly added processor is set to a sum of an OR logic function which ORs the processor types of the processors which are to receive the newly added software.

10. 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 including newly added processors, where each processor type is a string of a predetermined number 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 including newly added softwares, where each software type is a string of bits of the same predetermined number of bits as the processor types and includes 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 1located 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
