Abstract

A carrier rate module contains item rating instructions for rating an item for a carrier and self-registration instructions for storing registration information in a registry about the carrier rate module. The self-registration instructions are stored at an entry point with a predefined name so that a standard registration program can invoke the self-registration instructions through the entry point. The registration information stored in the registry includes a carrier identifier for the carrier in a one-to-one association with a module identifier. The module identifier indicates how to load the carrier rate module, so that a carrier manager librarian can identify an entry point of the item rating instructions based on the registration information stored in the registry.

Claims

1. A method of installing a carrier rate module for rating an item for a carrier on a computer system, said method comprising the computer-implemented steps of:

(a) making a computer readable medium bearing the carrier rate module accessible to the computer system; and

(b) executing self-registration instructions contained in the carrier rate module, causing the computer system to perform the step of storing registration information about the carrier rate module in a registry.

2. The method of claim 1, wherein the step of executing the sequences of self-registration instructions includes the computer-implemented steps of:

(a) executing a registration program with a parameter indicative of the carrier rate module;

(b) loading the carrier rate module into the executable space of the executing registration program;

(c) identifying an entry point having a predefined name for the sequences of self-registration instructions; and

(d) calling the entry point to execute the sequences of self-registration instructions.

3. The method of claim 1, wherein the step of storing registration information about the carrier rate module in a registry includes the step of storing in the registry a carrier identifier indicative of the carrier in one-to-one association with a module identifier indicative of how to load the carrier rate module.

4. The method of claim 3, wherein the step of storing a carrier identifier and a module identifier includes the step of storing a pathname of the carrier rate module in the registry.

5. A carrier management system, comprising:

(a) a plurality of carrier rate modules containing self-registration instructions and item rating instructions arranged to rate an item for respective carriers of a plurality of carriers;

(b) a registry recording registration information about the carrier rate modules; and

(c) a carrier management librarian module for loading a selected carrier rate module corresponding to a carrier specified by a client application based on registration information recorded in the registry;

wherein, the self-registration instructions of the selected carrier rate module, when executed, cause a computer system to store registration information for the selected carrier rate module in the registry.

6. The carrier management system of claim 5, wherein the self-registration instructions of a selected carrier rate module, when executed, further cause the computer system to store in the registry a carrier identifier indicative of the carrier in one-to-one association with a module identifier indicative of how to load the selected carrier rate module.

7. The carrier management system of claim 6, wherein the carrier management librarian module, which when executed, causes the computer system to:

(a) access the registry to obtain the carrier identifiers in a one-to-one association with the module identifiers;

(b) load a selected carrier rate module corresponding to the selected carrier, based on the module identifiers accessed in the registry, into the executable space of a the client application executing the carrier management librarian module; and

(c) identify an entry point of the item rating instructions in the selected carrier rate module based on an associated module identifier corresponding to the selected carrier.

8. The carrier management system of claim 7, wherein the carrier management librarian module is further configured to load all the carrier rate modules corresponding to the carriers into the executable space of the client application based on all the module identifiers recorded in the registry.

9. The carrier management system of claim 7, wherein the carrier management librarian module is further configured to:

(a) identify the selected carrier rate module from among the plurality of carrier rate modules based on an identifier specified by the client application; and

(b) load the selected carrier rate module after identifying the selected carrier rate module.

10. The carrier management system of claim 7, wherein the carrier management librarian module is further configured to dynamically link the carrier rate module into the executing client application.

11. The carrier management system of claim 7, further comprising a carrier rate data access module containing data access instructions arranged to access carrier rate data stored in a file on a non-volatile computer readable medium;

wherein at least one of the carrier rate modules is configured to;

(a) load the carrier rate data access module;

(b) execute the data access instructions for accessing the carrier rate data for the corresponding carrier; and

(c) execute the item rating instructions for rating the item based on the carrier rate data.

12. A computer-readable medium bearing a carrier rate module, said carrier rate module comprising:

(a) item rating instructions arranged to cause a computer system to rate items for a carrier; and

(b) self-registration instructions arranged to cause a computer system to store registration information for the carrier rate module in a registry.

13. The computer-readable medium of claim 12, wherein the self-registration instructions are further arranged to cause the computer system to store in the registry a carrier identifier indicative of the carrier in one-to-one association with a module identifier indicative of how to load the carrier rate module.

14. The computer-readable medium of claim 12, wherein the self-registration instructions are further arranged to cause the computer system to store a pathname of the carrier rate module in the registry.

15. The computer-readable medium of claim 12, wherein carrier rate module further includes instructions arranged to cause the computer system to:

(a) load a carrier rate data access module containing data access instructions arranged to access carrier rate data stored in a file on a nonvolatile computer readable medium;

(b) execute the data access instructions for accessing the carrier rate data for the corresponding carrier; and

(c) execute the item rating instructions for rating the item based on the carrier rate data.
