ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention is related in general to the field of telecommunications. More particularly, the invention is related to a programmable call processing system and method therefor.
BACKGROUND OF THE INVENTION
Telecommunications service providers who purchase switching systems may often desire to make modifications or extensions to the purchased system. The extensions are generally subscriber features which may provide additional revenue to the service provider. For example, the service provider may wish to implement new call processing features, develop custom features for special end users, collect specific information about a particular call, and collect specific traffic metering and measurement (TM&M) data about certain call processing operations.
However, adding extensions to the switching systems has proven difficult in the past because the switching systems are large and complex. Generally, only the switching system manufacturer and vendor has the expertise to affect the changes desired. Therefore, there may be some lead time required to implement these changes.
SUMMARY OF THE INVENTION
From the foregoing, it may be appreciated that a need has arisen for a call processing system and method that facilitates the provision of customized and non-standard call processing logic without long lead time. It is also advantageous for the service providers to have the capability and know-how to develop and implement the expanded subscription services in house.
In accordance with the present invention, a programmable call processing system and method therefor are provided which substantially eliminates or reduces disadvantages and problems associated with conventional call processing systems and methods.
According to one aspect of the invention, a programmable call processing system provides a standard call processing process performing call processing according to industry standard call models, at least one database storing call processing data accessible by the set of standard call processing process, and at least one customized call logic program for implementing extended subscriber features on the telecommunications switching system. Further, an application program interface provides access by at least one customized call logic program to at least one call processing database and further interrupting the standard call processing processes to execute the customized call logic program.
According to another aspect of the invention, a method for programmable call processing for a telecommunication switching system is provided. The method includes the steps of providing at least one customized call logic program extending subscriber services provided by a standard call processing process, initializing the standard call processing process, and upon the occurrence of a specified event, transferring control from the standard call processing process to at least one customized call logic program.
