Abstract

A method for reducing a call establishment time in real-time communication between at least two devices. The method includes: receiving, at a first internal server of a system, a first communication from a caller, wherein the first communication is a push request that comprises an attempt to initiate a connection with a callee; and sending a push notification via the first internal server to the callee, wherein the first internal server has at least two interfaces, wherein each interface of the at least two interfaces comprises a User Datagram Protocol (UDP) port, wherein the sending includes: embedding, by the first internal server and inside the push notification, an external UDP (IP, port) pair, of the at least two interfaces, to which the callee is able to connect.

Claims

1. A non-transitory computer-readable storage medium having instructions stored thereon which, when executed, cause a computer processor to perform a method for reducing a call establishment time in real-time communication between at least two devices, said method comprising:

receiving, at a first internal server of a system, a first communication from a caller, wherein said first communication is a push request that comprises an attempt to initiate a connection with a callee; and

sending a push notification via said first internal server to said callee, wherein said first internal server has at least two interfaces, wherein each interface of said at least two interfaces comprises a User Datagram Protocol (UDP) port, wherein said sending comprises;

embedding, by said first internal server and inside said push notification, an external UDP (IP, port) pair, of said at least two interfaces, to which said callee is able to connect.

2. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

receiving communication from at least one of a second internal server of said system, said caller, and said callee, wherein said receiving communication comprises;

receiving bundled information, wherein separate portions of said bundled information are capable of being serially sent or received between said first internal server, said second internal server, said caller, and said callee.

3. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

concurrently using said UDP port and a transmission control protocol (TCP) port to initiate a call or accept a call, wherein said each of said at least two interfaces comprises said TCP port;

utilizing said UDP port as a default port of at least said UDP port and said TCP port; and

if said UDP port is determined to be working, terminating a use of said TCP port.

4. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

seamlessly switching between network types associated with said callee and said caller, utilizing said UDP port.

5. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

relaying, by said first internal server, a set of communications between said caller, a second internal server, and said callee, wherein said set of communications comprises at least said first communication.

6. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

interpreting, by said first internal server, information contained within a control packet sent as part of said push request.

7. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

decrypting, by said first internal server, a control packet received at said first internal server, said control packet being part of said push request.

8. The non-transitory computer-readable storage medium of claim 7, further comprising instructions for:

accessing, by said first internal server, a password encapsulated in a header of said control packet; and

decrypting, by said first internal server, said control packet using said password.

9. The non-transitory computer-readable storage medium of claim 8, further comprising instructions for:

comparing, by said first internal server, a first signature corresponding to said caller with a second signature positioned in said header; and

authenticating said control packet, by said first internal server, if said first signature matches said second signature and said decrypting is successful.

10. The non-transitory computer-readable storage medium of claim 1, further comprising instructions for:

receiving dynamic configuration information from a second internal server of said system, wherein said dynamic configuration information comprises a selected protocol to utilize based on caller information and callee information, wherein said caller information and said callee information comprises a device time and a memory time of said caller and said callee, and wherein said selected protocol comprises a best fit method, wherein said selected protocol comprises an audio/video protocol.

11. A system for reducing a call establishment time in real-time communication between at least two devices, said system comprising:

a first internal server coupled with a second internal server, said first internal server comprising;

a push request receiver configured for receiving, at a first internal server of a system, a first communication from a caller, wherein said first communication is a push request and an attempt to initiate a connection with a callee; and

a push notification sender configured for sending a first push notification via said first internal server to said callee, wherein said first internal server has at least two interfaces, wherein each interface of said at least two interfaces comprises a User Datagram Protocol (UDP) port, wherein an external UDP port, of said at least two interfaces, is embedded inside said push notification, such that said callee is able to connect to said external UDP port.

12. The system of claim 11, wherein said first internal server further comprises:

a communication receiver configured for receiving communication from at least one of said second internal server of said system, said caller, and said callee, wherein said communication comprises;

bundled information, wherein separate portions of said bundled information are capable of being serially sent or received between said first internal server, said second internal server, said caller, and said callee.

13. The system of claim 11, wherein said first internal server further comprises:

a security module coupled with said first internal server and comprising a control packet, said control packet interpreter configured for interpreting information contained within a control packet sent as part of said push request.

14. The device of claim 13, wherein said security module further comprises:

a decrypter configured for decrypting a control packet received at said first internal server, said control packet being part of said push request.

15. The system of claim 14, wherein said security module further comprises:

a password accessor configured for accessing a password encapsulated in a header of said control packet, wherein said decrypter is further configured for decrypting said control packet using said password.

16. The system of claim 15, wherein said security module further comprises:

a signature comparer configured for comparing a first signature corresponding to said caller with a second signature positioned in said header; and

a control packet authenticator coupled with said signature comparer, said control packet authenticator configured for authenticating said control packet, if said first signature matches said second signature and said decrypting is successful.

17. The system of claim 11, wherein said first internal server further comprises:

a dynamic configuration information receiver configured for receiving dynamic configuration information from said second internal server, wherein said dynamic configuration information comprises a selected protocol to utilize based on caller information and callee information, wherein said caller information and said callee information comprises a device time and a memory time of said caller and said callee, and wherein said selected protocol comprises a best fit method and is an audio/video protocol.
