Peer to peer connection

1. A method comprising: sending, by a first communication device and to a second communication device, a request for establishing a peer-to-peer Internet Protocol (IP) connection between the first communication device and the second communication device; receiving, by the first communication device, a message from the second communication device, the message including information identifying: an identifier associated with the first communication device, and an IP address associated with the second communication device; generating, by the first communication device and based on the identifier, a signature associated with the first communication device; and sending, by the first communication device, the signature to the IP address of the second communication device to establish the peer-to-peer IP connection, the second communication device authenticating the first communication device based on the signature, and the peer-to-peer IP connection being established based on the second communication device authenticating the first communication device.

2. The method of claim 1 , further comprising: using the peer-to-peer IP connection to share an application with the second communication device.

3. The method of claim 1 , where sending the request to establish the peer-to-peer IP connection includes: sending one of a short message service message or a multimedia messaging service message, the one of the short message service message or the multimedia messaging service message including the request to establish the peer-to-peer IP connection.

4. The method of claim 1 , where sending the request to establish the peer-to-peer IP connection includes: sending a trigger to the second communication device, where the trigger causes the second communication device to start an application for enabling the second communication device to act as a server.

5. The method of claim 4 , where sending the trigger includes: addressing the request to establish the peer-to-peer IP connection to a particular port of the second communication device, where the particular port is associated with the application.

6. The method of claim 1 , further comprising: sending, via the peer-to-peer IP connection, a request to access a server associated with the second communication device.

7. The method of claim 6 , where the server is external to the second communication device.

8. A first device comprising: a processor to: send, to a second device, a request for establishing a peer-to-peer Internet Protocol (IP) connection between the first device and the second device; receive, from the second device, a message that includes information identifying: an identifier associated with the first device, and an IP address associated with the second device; generate, based on the identifier, a signature associated with the first device; and send the signature to the IP address of the second device to establish the peer-to-peer IP connection, the second device authenticating the first device based on the signature, and the peer-to-peer IP connection being established based on the second device authenticating the first device.

9. The first device of claim 8 , where the processor is further to: share multimedia content with the second device via the peer-to-peer IP connection.

10. The first device of claim 8 , where, when sending the request to establish the peer-to-peer IP connection, the processor is to: use a telephone number associated with the second device to send one of a short message service message or a multimedia messaging service message to the second device, the one of the short message service message or the multimedia messaging service message including the request to establish the peer-to-peer IP connection.

11. The first device of claim 8 , where, when sending the request to establish the peer-to-peer IP connection, the processor is to: use an application to send a trigger to the second device, where the trigger causes the second device to start a same application on the second device.

12. The first device of claim 8 , where, when sending the request to establish the peer-to-peer IP connection, the processor is to: direct the request to establish the peer-to-peer IP connection to a particular port of the second device, where receiving the request to establish the peer-to-peer IP connection at the particular port causes the second device to automatically start an application that is associated with the particular port.

13. The first device of claim 8 , where the processor is further to: send, via the peer-to-peer IP connection, a request to access a server associated with the second device.

14. The first device of claim 8 , where, when receiving the message from the second device, the processor is to: receive, from the second device, one of: a short message service message, or a multimedia messaging service message.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by a processor of a first device, cause the processor to: send, to a second device, a request for establishing a peer-to-peer Internet Protocol (IP) connection between the first device and the second device; receive, from the second device, a message that includes information identifying: an identifier associated with the first device, and an IP address associated with the second device; generate, based on the identifier, a signature associated with the first device; and send the signature to the IP address of the second device to establish the peer-to-peer IP connection, the second device authenticating the first device based on the signature, and the peer-to-peer IP connection being established based on the second device authenticating the first device.

16. The non-transitory computer-readable medium of claim 15 , where the instructions further comprise: one or more instructions to share multimedia content with the second device via the peer-to-peer IP connection.

17. The non-transitory computer-readable medium of claim 15 , where the one or more instructions to send the request for establishing the peer-to-peer IP connection include: one or more instructions to use a telephone number associated with the second device to send one of a short message service message or a multimedia messaging service message to the second device, the one of the short message service message or the multimedia messaging service message including the request for establishing the peer-to-peer IP connection.

18. The non-transitory computer-readable medium of claim 15 , where the one or more instructions to send the request to establish the peer-to-peer IP connection include: one or more instructions to use an application to send the request for establishing the peer-to-peer connection to the second device, where the request for establishing the peer-to-peer connection includes a trigger, where the trigger causes the second device to start a same application on the second device.

19. The non-transitory computer-readable medium of claim 15 , where the one or more instructions to send the request for establishing the peer-to-peer IP connection include: direct the request for establishing the peer-to-peer IP connection to a particular port of the second device, where the particular port is associated with a particular application, and where receiving the request for establishing the peer-to-peer IP connection at the particular port causes the second device to automatically start the particular application.

20. The non-transitory computer-readable medium of claim 15 , where the instructions further comprise: one or more instructions to browse a server associated with the second device via the peer-to-peer IP connection.
