Abstract

An operator MUX interface (OMI) (102) includes a data base manager (203) that manages at least two data bases. The first comprises a substantially non-temporary data base, and the second comprises a substantially temporary data base. The latter includes information from both the first data base, and other information as well. The data base manager (203) automatically alters the data storage structure of the second data base whenever either the data storage structure for the first data base is changed, or whenever new information must be added to the second data base, and the data storage structure of the second data base will not readily accommodate that addition.

Claims

1. A method of maintaining data in a communications network having at least first and second communication systems, the method comprising the steps of:

providing a first data base having a data storage structure directly related to characteristics of operating parameters for the first communication system and storing a first set of information relating to operating parameter characteristic values for the first communication system;

providing a second data base having a data storage structure directly related to characteristics of operating parameters for the second communication system and storing a second set of information and a third set of information, wherein the second set of information includes at least some of the first set of information, and wherein the third set of information relates to operating parameter characteristic values for the second communication system;

modifying the data storage structure of the first data base by changing the operating parameter characteristics when the operating parameter characteristic values for the first communication system are modified due to an environmental change in the first communication system and said operating parameter characteristic value modification cannot be readily accommodated by a current data storage structure of the first data base;

automatically modifying the data storage structure of the second data base by changing the operating parameter characteristics whenever any of the following occur;

the data storage structure of the first data base is modified; and

new operating parameter characteristic values must be added to the second data base, and the new operating parameter characteristic values cannot be readily accommodated by a current data storage structure of the second data base.

2. The method of claim 1, wherein the first data base comprises a substantially non-temporary data base.

3. The method of claim 2, wherein the first data base resides in EEPROM.

4. The method of claim 2, wherein the first data base is not altered during ordinary operation and use of the first data base.

5. The method of claim 1, wherein the second data base comprises a substantially temporary data base.

6. The method of claim 5, wherein the second data base resides in EEPROM.

7. The method of claim 5, wherein the second data base is altered, from time to time, during ordinary operation and use of the second data base.

8. The method of claim 1, wherein:

the first data base comprises a substantially non-temporary data base; and

the second data base comprises a substantially temporary data base.

9. The method of claim 8, wherein:

the first data base is not altered during ordinary operation and use of the first data base;

the second data base is altered, from time to time, during ordinary operation and use of the second data base.

10. An operator interface for use in interfacing a communications console to a radio communication system network that is comprised of at least a first and second radio communication system, the communications console being a part of the first radio communication system, the operator interface comprising:

first data base means having a data storage structure directly related to characteristics of operating parameter for the first communication system and for storing, on a substantially non-temporary basis, a first set of information relating to operating parameter characteristic values for the first radio communication system wherein the data storage structure of the first data base means can be modified by changing the operating parameter characteristics when the operating parameter characteristic values for the first communication system are modified due to an environmental change in the first communication system and said operating parameter characteristic value modification cannot be readily accommodated by a current data storage structure of the first data base means;

second data base means having a data storage structure directly related to characteristics of operating parameters for the second communication system and for storing, on a substantially temporary basis;

a second set of information comprising at least part of the first set of information; and

a third set of information relating to operating parameter characteristic values for at least the second radio communication system;

data base management means operably coupled to the first data base means and the second data base means, for automatically modifying the data storage structure of the second data base by changing the operating parameter characteristics whenever any of the following occur;

the data storage structure of the first data base is modified; and

new operating parameter characteristic values must be added to the second data base, the new operating parameter characteristic values not being readily accommodated by a current data storage structure of the second data base.
