Abstract

A system and method may provide identifying an initialization signal, receiving one or more pattern elements after identifying the initialization signal, and analyzing the one or more pattern elements based on an identified dialing plan to determine whether the one or more pattern elements correspond to a complete address. The system and method also may provide identifying that the one or more pattern elements or a subsequence of the one or more pattern elements are associated with a command.

Claims

1. A method comprising:

identifying an initialization signal;

receiving one or more pattern elements after identifying the initialization signal;

analyzing the one or more pattern elements based on an identified dialing plan to determine whether the one or more pattern elements correspond to a complete address, wherein the dialing plan comprises one or more matching rules and wherein the analyzing compares the one or more pattern elements for alternative matches within the one or more matching rules;

forwarding the one or more pattern elements in a connection request to a server if the one or more pattern elements correspond to the complete address;

identifying that the one or more pattern elements or a subsequence of the one or more pattern elements match a matching rule that identifies a command, wherein the command is based on the one or more matching rules in the dialing plan; and

generating a tone or a response message based on the command.

2. The method of claim 1, wherein the one or more pattern elements correspond to the complete address if the one or more pattern elements satisfy the one or more matching rules.

3. The method of claim 1, further comprising:

querying the server for the dialing plan; and

receiving the dialing plan.

4. The method of claim 1, further comprising, when the analysis determines that the one or more pattern elements do not correspond to the complete address:

receiving one or more additional pattern elements; and

determining whether the one or more pattern elements and the one or more additional pattern elements correspond to the complete address.

5. The method of claim 1, wherein the complete address includes a destination address code.

6. The method of claim 1, wherein the complete address includes a destination address code and a modifier code.

7. The method of claim 6, wherein the modifier code comprises a feature access code, a facility access code, or a carrier access code.

8. The method of claim 1, wherein the analysis determines that the one or more pattern elements correspond to the complete address after an expiration of a predetermined amount of time.

9. The method of claim 1, further comprising:

identifying an end-of-dialing pattern element in the one or more pattern elements; and

determining that the one or more pattern elements correspond to the complete address based on the identified end-of-dialing pattern element.

10. The method of claim 1, further comprising inserting a pattern element based on the command.

11. The method of claim 1, further comprising identifying a service code based on the command.

12. The method of claim 1, further comprising monitoring a timer based on the command.

13. The method of claim 1, wherein the one or more pattern elements comprise digital representations of DTMF signals or digital representations of pulse dialing signals.

14. The method of claim 1, further comprising determining whether the one or more pattern elements correspond to an emergency call.

15. A non-transitory computer readable storage media comprising code to perform the acts of the method of claim 1.

16. A system comprising:

an initialization processor to identify an initialization signal received from an communication device;

a receiver communicatively coupled to the initialization processor and configured to receive one or more pattern elements after the initialization processor identifies the initialization signal;

an analysis processor communicatively coupled to the receiver and configured to analyze the one or more pattern elements based on a dialing plan to determine whether the one or more pattern elements correspond to a complete address, the analysis processor further being configured to identify that the one or more pattern elements or a subsequence of the one or more pattern elements match a matching rule that identifies a command; and

wherein the dialing plan comprises one or more matching rules and wherein the analysis processor compares the one or more pattern elements for alternative matches within the one or more matching rules, wherein the command is based on the one or more matching rules in the dialing plan, wherein the analysis processor is further configured to generate a tone or response message based on the command.

17. The system of claim 16, further comprising:

a buffer to store the one or more pattern elements received by the receiver.

18. The system of claim 16, further comprising:

a request processor to generate a connection request based on the one or more pattern elements if the analysis processor determines that the one or more pattern elements correspond to the complete address.

19. The system of claim 16, further comprising:

a registration processor to query a server and to receive the dialing plan from the server.

20. A system comprising:

a server;

an gateway device communicatively coupled to a communication device and to the server, the gateway device comprising;

an initialization module to identify an initialization signal received from the communication device;

a receiver module communicatively coupled to the initialization module and configured to receive one or more pattern elements after the initialization module identifies the initialization signal; and

an analysis module communicatively coupled to the receiver module and configured to analyze the one or more pattern elements based on a dialing plan to determine whether the one or more pattern elements correspond to a complete address, the analysis module further being configured to identify that the one or more pattern elements or a subsequence of the one or more pattern elements match a matching rule that identifies a command, wherein the dialing plan comprises one or more matching rules and wherein the analysis module compares the one or more pattern elements for alternative matches within the one or more matching rules, wherein the command is based on the one or more matching rules in the dialing plan, wherein the analysis module is further configured to generate a tone or response message based on the command.
