Abstract

Methods and apparatus for dynamically loading signaling definition files for operations involving multiple signaling variants. Transmission links that transmit communications corresponding to one of several signaling variants are associated with one of several signaling definition files, where each signaling definition file corresponds to one of the signaling variants and, thus, can be employed during switching, signaling, and other processing of the communications without requiring such processing to be specifically hard-coded, or even designed, for each individual signaling variant.

Claims

1. An apparatus, comprising:

a plurality of transmission links collectively configured to transmit a plurality of communications each including at least one of voice data and signaling data corresponding to one of a plurality of signaling system variants;

a plurality of signaling definition files each corresponding to one of the plurality of signaling system variants; and

an associative device configured to associate each of the plurality of communications with a corresponding one of the plurality of signaling definition files, wherein the plurality of signaling definition files is stored in memory prior to receiving the plurality of communications, wherein each of the plurality of signaling definition files is dynamically loadable on an as-needed basis and includes commands and signaling event definitions usable, by a signaling interpreter, for processing signaling data associated with a corresponding communication.

2. The apparatus of claim 1 wherein the variants are region 2 (R2) signaling system variants.

3. The apparatus of claim 1 wherein the variants are channel associated signaling (CAS) signaling system variants.

4. The apparatus of claim 1 wherein the variants are common channel signaling (CCS) signaling system variants.

5. The apparatus of claim 1 wherein the variants correspond to at least one of inbound and outbound signaling.

6. The apparatus of claim 1 wherein the associative device is configured to associate each of the transmission links with a corresponding one or more of the signaling definition files.

7. The apparatus of claim 1 wherein the association of each of the plurality of communications with a corresponding one of the plurality of signaling definition files permits line and register signaling within a system in which the apparatus is located.

8. The apparatus of claim 1 wherein each signaling definition file is at least one of a line signaling definition file and a register signaling definition file.

9. The apparatus of claim 1 further comprising an input for dynamically-receiving the plurality of signaling definition files.

10. The apparatus of claim 1 further comprising at least one compiler function configured to compile one or more of the plurality of signaling definition files.

11. The apparatus of claim 1 further comprising at least one conversion function configured to convert at least one of a language, a format, and a protocol of at least one of the signaling definition files.

12. The apparatus of claim 1 further comprising at least one transcoding function configured to perform at least one of encoding, decoding, and transcoding of at least one of the signaling definition files.

13. The apparatus of claim 1 further comprising at least one translator function configured to translate at least one of the signaling definition files between first and second languages, wherein the first and second languages are each one of a programming language and a machine language.

14. The apparatus of claim 1 wherein the apparatus is a media gateway configured to perform switching.

15. A method, comprising:

receiving a plurality of communications each corresponding to one of a plurality of signaling variants;

associating each of the plurality of communications with one of a plurality of signaling definition files, wherein the plurality of signaling definition files is stored in memory prior to receiving the plurality of communications, wherein each of the plurality of signaling definition files is dynamically loadable on an as-needed basis and includes commands and signaling event definitions usable, by a signaling interpreter, for processing signaling data associated with a corresponding communication, wherein each of the signaling definition files corresponds to one of the signaling variants; and

translating ones of the plurality of received communications by employing associated ones of the plurality of signaling definition files.

16. The method of claim 15 further comprising dynamically loading the signaling definition files.

17. The method of claim 15 wherein associating includes binding each of the communications with an associated one of the signaling definition files.

18. The method of claim 15 wherein the signaling definition files include at least one of a plurality of line signaling definition files and a plurality of register signaling definition files.

19. The method of claim 15 further comprising establishing a communication channel for each of the communications pursuant to the association of that communication with a corresponding one of the signaling definition files.

20. A method, comprising:

receiving a communication corresponding to a signaling variant;

associating the communication with a signaling definition file corresponding to the signaling variant, the plurality of signaling definition files is stored in memory prior to receiving the plurality of communications, wherein each of the plurality of signaling definition files is dynamically loadable on an as-needed basis and includes commands and signaling event definitions usable, by a signaling interpreter, for processing signaling data associated with a corresponding communication; and

translating the received communication by employing the associated signaling definition file.

21. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:

receiving a communication corresponding to a signaling variant;

associating the communication with a signaling definition file corresponding to the signaling variant, wherein the plurality of signaling definition files is stored in memory prior to receiving the plurality of communications, wherein each of the plurality of signaling definition files is dynamically loadable on an as-needed basis and includes commands and signaling event definitions usable, by a signaling interpreter, for processing signaling data associated with a corresponding communication; and

translating the received communication by employing the associated signaling definition file.
