Abstract

A system and method are provided for implementing a web server on a mobile station. A first mobile station may include a database of information. A network address for the first mobile station may be transmitted to a second mobile station to enable the second mobile station to communicate with the first mobile station directly over a wireless network. The second mobile station may then be provided access to the database of information by communicating directly over the wireless network with the first mobile station, wherein the first mobile station operates as the wireless server for the second mobile station.

Claims

1. A wireless server for use within a wireless network, comprising:

a communication subsystem operable to send and receive communications over the wireless network;

a memory subsystem operable to store data and program information, including a server database;

a processing subsystem operable to store and retrieve data in the memory subsystem, execute programs stored in the memory subsystem, and cause the communication subsystem to transmit and receive communications over the wireless network; and

a wireless server module stored in the memory subsystem and executed by the processing subsystem, the wireless server module when executed by the processing subsystem being operable to cause the wireless server to transmit a network address for the wireless server to a wireless client, the network address enabling the wireless client to communicate with the wireless server directly over the wireless network to access information in the server database;

wherein the network address is an IP address of the wireless server, and the IP address is dynamically assigned by the wireless network;

wherein the wireless server module includes an IP monitoring agent that is operable to monitor the IP address assigned to the wireless server and transmit an updated network address to an IP address exchange service if the IP address is changed, wherein the IP address exchange service is configured to forward the updated network address to a plurality of wireless clients that are registered to access information in the server database, the plurality of wireless clients including one or more wireless clients that are not in a communication session with the wireless server when the updated network address is forwarded;

wherein the IP address exchange service is external to the wireless server and maintains a list of all wireless clients that are registered to receive IP address updates from the wireless server.

2. The wireless server of claim 1, wherein the wireless server module causes the wireless server to transmit the network address from the wireless server to the wireless client in an electronic message (email) transmitted via an electronic messaging service.

3. The wireless server of claim 1, wherein the wireless server module causes the wireless server to transmit the network address from the wireless server to the wireless client in a short messaging server (SMS) message transmitted via a SMS messaging service center.

4. The wireless server of claim 1, wherein the wireless server module causes the wireless server to transmit the network address from the wireless server to the wireless client in a short messaging server (SMS) message transmitted via an IP address exchange service.

5. The wireless server of claim 4, wherein the IP address exchange service maintains a list of a plurality of wireless clients that are registered to access information in the server database.

6. The wireless server of claim 1 wherein the IP monitoring agent is operable to transmit an updated network address to the wireless client if the IP address is changed.

7. The wireless server of claim 6, wherein the IP monitoring agent determines a plurality of wireless clients that are registered to receive information from the wireless server and is operable to transmit an updated network address to the plurality of wireless clients if the IP address of the wireless server is changed.

8. The wireless server of claim 1, wherein the wireless server module is further operable to receive a network address of the wireless client to enable two-way communication between the wireless server and the wireless client directly over the wireless network.

9. A method of providing a wireless server having access to a database of information for use within a wireless network, comprising:

assigning a network address to the wireless server upon the wireless server connecting with an Internet service;

the wireless server initiating a communication by distributing the wireless server network address to a wireless client, the network address enabling the wireless client to communicate with the wireless server directly over a wireless network;

the wireless client being operable to access the database of information by communicating directly over the wireless network with the wireless server using the network address of the wireless server, wherein the network address of the wireless server is an IP address;

monitoring the IP address of the wireless server; and

if the IP address of the wireless server changes, transmitting an updated network address to an IP address exchange service, located external to the wireless server, wherein the IP address exchange service is configured to forward the updated network address to the wireless client, the wireless client registered to access information in the database of information, wherein the IP address exchange service maintains a list of a plurality of wireless clients that are registered to receive IP address updates from the wireless server and forwards the updated network address to the plurality of wireless clients, the plurality of wireless clients including one or more wireless clients that are not in a communication session with the wireless server when the updated network address is forwarded.

10. The method of claim 9, further comprising receiving a network address for the wireless client at the wireless server to enable two-way communication between the first mobile station and the second mobile station.

11. The method of claim 9, further comprising:

consolidating an address space of two networks through a VPN or wide area network bridge using the mobile server, whereby a number of directly addressable IP addresses is increased.

12. The method of claim 9, wherein the wireless server distributes the network address to the wireless client in an e-mail transmitted via an electronic messaging service.

13. The method of claim 9, wherein the wireless server distributes the network address to the wireless client in an SMS message transmitted via an SMS messaging service center.

14. The method of claim 9, wherein the IP address of the wireless server is dynamically assigned by the wireless network;

the method further comprising;

monitoring the dynamic IP address of the wireless server; and

if the dynamic address of the wireless server is changed, then transmitting an updated IP address for the wireless server to the wireless client, the updated IP address enabling the wireless client to communicate with the wireless server directly over the wireless network.
