Determining characteristics of a mobile user of a network

1. A system for determining characteristics of a mobile user of a network, comprising:

a first provider; and

a mobile device communicating with the first provider, wherein a communication with the first provider includes a header having user characteristics, wherein the user characteristics are based on usage information accumulated by a network service provider during mobile device communications, wherein the user characteristics are provided to the mobile device from the network service provider, wherein the first provider and the network service provider are different providers, and wherein the first provider is configured to determine a content to provide to the mobile device based on the user characteristics in the header.

2. The system of claim 1 , further comprising a server to supply a user characteristics legend to the first provider for use to interpret at least a first portion of the user characteristics.

3. The system of claim 2 , wherein the server is further configured to modify the user characteristics to prevent the first provider from interpreting the user characteristics.

4. The system of claim 3 , further comprising another user characteristics legend, wherein the server is further configured to provide the other user characteristics legend to the first provider to interpret the user characteristics.

5. The system of claim 2 , wherein the first portion of the user characteristics that the first provider can interpret is based on a first subscription.

6. The system of claim 5 , further comprising a second provider to interpret a second portion of the user characteristics based on a second subscription.

7. The system of claim 6 , wherein the second provider is further configured to decrypt the second portion of the user characteristics based on the second subscription.

8. The system of claim 1 , further comprising:

a first encryption key for use by a server to encrypt the user characteristics in the header; and

a first decryption key for use by the first provider to decrypt the user characteristics in the header.

9. The system of claim 8 , further comprising a second encryption key, wherein the server is further configured to encrypt the user characteristics based on the second encryption key to prevent the first provider from decrypting the user characteristics.

10. The system of claim 9 , further comprising a second decryption key, wherein the server is further configured to provide the second decryption key to the first provider to decrypt the user characteristics.

11. The system of claim 1 , further comprising a server to provide a decryption key and a user characteristics legend to the first provider during off-peak hours.

12. The system of claim 1 , wherein the user characteristics comprise at least one of a hardware characteristic, a software characteristic, an operating system, a geographic location, demographics, and usage information.

13. The system of claim 1 , wherein the mobile device is one of a mobile telecommunication device, a mobile handset, a personal digital assistant, a mobile computer, a handheld gaming device, a wireless mobile device, a pager, a digital camera, a digital music player, and a digital calculator.

14. A computer implemented method for determining characteristics of a mobile user of a network, comprising:

receiving, at a provider, a mobile device communication, wherein the mobile device communication includes a header having user characteristics, wherein the user characteristics are based on usage information accumulated by a network service provider during mobile device communications, wherein the header is provided by the network service provider in response to a request by the mobile communication device to provide the mobile device communication to the provider, wherein the provider and the network service provider are different providers, and wherein the user characteristics comprise at least one of: a hardware characteristic, a software characteristic, an operating system, demographic information, or usage information; and

determining a content to provide to the mobile device based on the user characteristics in the header.

15. The computer implemented method of claim 14 , further comprising collecting, by the network service provider, usage information for a user of the mobile device during a communication with the provider for inclusion in the user characteristics.

16. The computer implemented method of claim 14 , further comprising updating the user characteristics.

17. A computer implemented method for determining characteristics of a mobile user of a network, comprising:

providing user characteristics to a mobile device from a network service provider, wherein the user characteristics are based on usage information accumulated by the network service provider during mobile device communications;

receiving, at a provider, a communication from the mobile device via the network, wherein the communication includes a header having the user characteristics, wherein the provider and the network service provider are different providers;

receiving, at the provider, a user characteristics legend;

interpreting, at the provider, at least a first portion of the user characteristics in the header using the user characteristics legend; and

determining a content to provide to the mobile device based on the interpreted user characteristics in the header.

18. The computer implemented method of claim 17 , wherein the provider is at least one of an advertisement provider and a content provider.

19. The computer implemented method of claim 17 , wherein the content is a selected advertisement transmitted to the mobile device based on the user characteristics and the mobile device is one of a portable computer, a tablet computer, and a laptop computer.

20. The computer implemented method of claim 19 , wherein the advertisement is one of an unsolicited advertisement and an advertisement displayed with requested content.
