System and method of exchanging identification information for mobile stations
View Patent ↗A system is provided for allowing mobile stations to exchange identification information using a predetermined communication path for the purpose of obtaining identification information to use in establishing a different communication path for communicating.
1. A method in a mobile device comprising:
detecting that a first network identification code associated with the mobile device has changed and, in response, sending a first message comprising the first network identification code to another mobile device;
receiving from the other mobile device a second message, the second message comprising a second network identification code that is associated with the other mobile device; and
requesting a communication link with the other mobile device using the second network identification code.
2. The method of claim 1 wherein a message type for the first and second messages is the same and wherein the communication link is for transmitting messages of a different type than the message type of the first and second messages.
3. The method of claim 2 wherein the message type of the first and second messages is selected from a group comprising an email message, a SMS message and a HTTP message.
4. The method of claim 1 wherein the communication link is for transmitting messages of a different type than a message type of the second message.
5. The method of claim 4 wherein the message type of the second message is selected from a group comprising an email message, a SMS message and a HTTP message.
6. The method of claim 1 wherein the communication link is for transmitting messages of a different type than a message type of the first message.
7. The method of claim 6 wherein the message type of the first message is selected from a group comprising an email message, a SMS message and a HTTP message.
8. The method of claim 1 wherein the first message is sent using a first type of service gateway and the communication link does not use the first type of service gateway.
9. The method of claim 1 wherein the second message is received using a second type of service gateway and the communication link does not use the second type of service gateway.
10. The method of claim 1 wherein the first message is sent using a first type of service gateway, the second message is received using a second type of service gateway, and the communication link does not use either the first type or the second type of service gateway.
11. The method of claim 1 wherein the first message is sent and the second message is received using a same type of service gateway, and wherein the communication link does not use the same type of service gateway.
12. The method of claim 1 wherein the first and second network identification codes comprise IP addresses assigned by a wireless network.
13. The method of claim 1 wherein the communication link is a peer-to-peer communication link, an instant messaging communication link, or a communication channel for a web server to provide web pages for information exchange.
14. The method of claim 1 further comprising:
storing the second network identification code in a mapping table wherein the mapping table is used to store email addresses or SMS addresses of mobile devices that are registered as associates.
15. A mobile device configured to:
detect that a first network identification code associated with the mobile device has changed and, in response, send a first message comprising the first network identification code to another mobile device;
receive from the other mobile device a second message, the second message comprising a second network identification code that is associated with the other mobile device; and
request a communication link with the other mobile device using the second network identification code.
16. The mobile device of claim 15 wherein a message type for the first and second messages is the same and wherein the communication link is for transmitting messages of a different type than the message type of the first and second messages.
17. The mobile device of claim 16 wherein the message type of the first and second messages is selected from a group comprising an email message, a SMS message and a HTTP message.
18. The mobile device of claim 15 further comprising:
a mapping table in memory for storing the second network identification code, wherein the mapping table is used to store email addresses or SMS addresses of mobile devices that are registered as associates.
