Abstract

A software platform in one example comprises a plurality of software applications. The plurality of software applications comprise a first software application that performs a determination of a load level associated with the first software application. The first software application employs the determination of the load level to manage a quality of service level associated with the first software application.

4. The software platform of claim 3, wherein the first operational mode comprises an overload mode of the plurality of overload modes that is configured to reduce the load level associated with the first software application;

wherein the first software application operates based on the first operational mode;

wherein the first software application reduces the load level to manage the quality of service level associated with the first software application.

5. The software platform of claim 4, wherein the first operational mode comprises one or more call gapping procedures;

wherein the first software application performs the one or more call gapping procedures to manage the quality of service level associated with the first software application.

6. The software platform of claim 3, wherein the first software application selects a second operational mode upon an occurrence of a predetermined event.

7. The software platform of claim 6, wherein the predetermined event comprises an expiration of a predetermined timer that corresponds to the first operational mode;

wherein the first software application selects the second operational mode upon the expiration of the predetermined timer that corresponds to the first operational mode.

8. The software platform of claim 6, wherein the determination of the load level comprises a first determination of a first load level;

wherein the first software application comprises a load monitor that performs the first determination of the first load level;

wherein the comparison of the load level with the plurality of predetermined thresholds comprises a first comparison of the first load level with the plurality of predetermined load thresholds;

wherein the load monitor performs, upon the occurrence of the predetermined event, a second determination of a second load level associated with the first software application;

wherein the first software application performs a second comparison of the second load level with the plurality of predetermined thresholds;

wherein the first software application selects a second operational mode, of the plurality of operational modes, that corresponds to the second load level;

wherein the first software application manages the quality of service level based on the second operational mode.

9. The software platform of claim 1, wherein the software application employs one or more resource level indicators to perform the determination of the load level.

10. The software platform of claim 9, wherein the one or more resource level indicators comprise resource level indicators for one or more of:

processor usage;

memory usage;

communication port usage;

response time; and

/or

calls in progress;

wherein the software application employs the one or more resource level indicators for the processor usage, the memory usage, the communication port usage, the response time, and/or the calls in progress to perform the determination of the load level.

11. The software platform of claim 1, wherein the software application employs one or more previous load levels and/or one or more near real-time load levels to select the operational mode.

12. The software platform of claim 1, wherein the first software application performs one or more of:

a ringback tone service;

a call waiting service; and

/or

a voicemail service.

13. The software platform of claim 1, wherein each software application of the plurality of software applications comprises a load monitor that performs a determination of a load level associated with each software application of the plurality of software applications;

wherein each software application of the plurality of software applications employs the determination of the load level associated with each software application of the plurality of software applications to manage a quality of service associated with each software application of the plurality of software applications.

14. A call processing platform, comprising:

an application server, of a cellular communication network, that comprises a plurality of call processing applications that perform one or more of;

a ringback tone service;

a call waiting service; and

/or

a voicemail service;

wherein the plurality of call processing applications comprise a first call processing application that comprises a load monitor that determines a number of calls in progress of the first call processing application;

wherein the first call processing application performs a comparison of the number of calls in progress with a plurality of predetermined load thresholds that correspond to a plurality of operational modes;

wherein the first call processing application selects a first operational mode, from the plurality of operational modes, that corresponds to the number of calls in progress;

wherein the plurality of predetermined load thresholds comprise a normal threshold that corresponds to the normal mode, wherein the plurality of predetermined load thresholds comprise one or more overload thresholds that correspond to the plurality of overload modes;

wherein the first call processing application selects the normal mode if the number of calls in progress is less than or equal to the normal threshold;

wherein if the number of calls in progress is greater than the normal threshold the first call processing application selects an overload mode that corresponds to a highest overload threshold, of the one or more overload thresholds, that is lower than the number of calls in progress;
