Method and system for decoding tokenized session initiated protocol packets
View Patent ↗The present invention relates to a method of decoding tokenized Session Initiated Protocol. A token from a tokenized Session Initiated Protocol packet is received. A decoding table is accessed and the corresponding entry for the token is determined. The token is executed according to the corresponding entry. This may be done for all tokens in a tokenized Session Initiated Packet. Once the tokens have been executed according to their entries in a decoding table, the decoded tokenized Session Initiated Protocol packet is provided.
1. A method of decoding tokenized Session Initiated Protocol, the method comprising:
receiving, at a server, a first tokenized Session Initiated Protocol packet;
extracting, at the server, a string table from a user datagram payload in the first tokenized Session Initiated Protocol packet;
decoding, at the server, the string table from the user datagram payload;
creating, at the server, an index for the string table, wherein the index includes an IP address for a server that generated the first tokenized Session Initiated Protocol packet;
storing, at the server, the index for the string table;
accessing, at the server, a decoding table;
determining, at the server, a corresponding entry in the decoding table for each token in the first tokenized Session Initiated Protocol packet;
executing, at the server, the corresponding entry for the each token to decode the first tokenized Session Initiated Protocol packet; and
displaying, through a user interface communicatively coupled to the server, a decoded representation of the first tokenized Session Initiated Protocol packet on a display device as a Session Initiated Protocol message.
2. The method of claim 1 , wherein executing the corresponding entry decodes the each token into Session Initiated Protocol element.
3. The method of claim 1 , wherein said each token is a textual element representing a Session Initiated Protocol element.
4. The method of claim 1 , further comprising:
receiving, at the server, the user datagram payload.
5. The method of claim 4 , further comprising:
determining, at the server, whether the user datagram payload is tokenized Session Initiated Protocol.
6. The method of claim 1 , wherein the corresponding entry for the each token to decode is a subroutine.
7. The method of claim 6 , wherein the subroutine includes one of receiving a next token, accessing a token dictionary, accessing the string table or combinations thereof.
8. A method for providing decoded tokenized Session Initiated Protocol packets for review, the method comprising:
receiving, at a server, a tokenized Session Initiated Protocol packet;
receiving, at the server, a first token from the tokenized Session Initiated Protocol packet;
extracting, at the server, a string table from a user datagram payload in the tokenized Session Initiated Protocol packet;
decoding, at the server, the string table from the user datagram payload;
creating, at the server, an index for the string table, wherein the index includes attribute values describing a server that generated the tokenized Session Initiated Protocol packet;
storing, at the server, the index for the string table;
accessing, at the server, a decoding table;
determining, at the server, a corresponding entry in the decoding table for the first token;
executing, at the server, the corresponding entry to decode the first token; and
displaying, through a user interface communicatively coupled to the server, a decoded representation of the first token.
9. The method of claim 8 , further comprising:
receiving, at the server, a second token from the tokenized Session Initiated Protocol packet;
accessing, at the server, the decoding table;
determining, at the server, the corresponding entry in the decoding table for the second token; and
executing, at the server, the corresponding entry to decode the second token.
10. A method of decoding tokenized Session Initiated Protocol, the method comprising:
receiving, at a server, a first tokenized Session Initiated Protocol packet;
extracting, at the server, a string table from a user datagram payload in the first tokenized Session Initiated Protocol packet;
decoding, at the server, the string table from the user datagram payload;
creating, at the server, an index for the string table;
storing, at the server, the index for the string table;
accessing, at the server, a decoding table;
determining, at the server, a corresponding entry in the decoding table for each token in the first tokenized Session Initiated Protocol packet; and
executing, at the server, the corresponding entry for the each token to decode the first tokenized Session Initiated Protocol packet.
11. The method of claim 10 , wherein executing the corresponding entry decodes the each token into Session Initiated Protocol element.
12. The method of claim 10 , wherein said each token is a textual element representing a Session Initiated Protocol element.
13. The method of claim 10 , further comprising:
receiving, at the server, the user datagram payload.
14. The method of claim 13 , further comprising:
determining, at the server, whether the user datagram payload is tokenized Session Initiated Protocol.
15. The method of claim 10 , wherein the corresponding entry for the each token to decode is a subroutine.
16. The method of claim 15 , wherein the subroutine includes one of receiving a next token, accessing a token dictionary, accessing the string table or combinations thereof.
17. The method of claim 10 , further comprising displaying, through a user interface communicatively coupled to the server, a decoded representation of the first tokenized Session Initiated Protocol packet on a display device as a Session Initiated Protocol message.
18. The method of claim 10 , wherein the first tokenized Session Initiated Protocol packet contains information used to set up a phone call involving a wireless device.
