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 mobile station operating as a wireless server within a wireless network, the mobile station comprising:

a wireless server module configured to provide, to wireless clients, access to a database of information;

a communication subsystem configured to send and receive communications over the wireless network, wherein the wireless network assigns a first dynamic network address to the mobile station that may be used to enable direct two-way communication with the wireless server module over the wireless network;

the database for storing information to be accessed from the wireless server module over the wireless network; and

a network address monitoring agent that is configured to

maintain a registration database that includes a list of the wireless clients along with contact information for each of the wireless clients,

transmit the first dynamic network address for the mobile station to the wireless clients on the list using the contact information in the registration database,

detect a new dynamic network address being assigned to the mobile station to replace the first dynamic network address, and

in response to detecting the new dynamic network address, transmit the new dynamic network address to the wireless clients on the list using the contact information.

2. The mobile station operating as a wireless server of claim 1, wherein any updates in the dynamic network address are transmitted to the wireless client via email.

3. The mobile station operating as a wireless server of claim 1, wherein the dynamic network address is an IP address.

4. The mobile station operating as a wireless server of claim 1, wherein the network address monitoring agent is configured to transmit said updates in the dynamic network address to the wireless client using an email message.

5. The mobile station operating as a wireless server of claim 1, wherein the network address monitoring agent is configured to transmit said updates in the dynamic network address to the wireless client using a short message service (SMS) message.

6. A method in a mobile station operating as a wireless server for providing access to a database of information, the method comprising:

maintaining a registration database that includes a list of wireless clients that access a database of information via the wireless server, the registration database further including contact information for the wireless clients;

receiving a first temporary network address that is dynamically assigned by a wireless network;

transmitting the first temporary network address to the wireless clients on the list;

detecting that the wireless network has assigned a new temporary network address to replace for the first temporary network address; and

in response to receiving the new temporary network address, transmitting the new temporary network address to the wireless clients on the list using the contact information in the registration database.

7. The method of claim 6, wherein said transmitting the new temporary network address comprises sending the new temporary network address to a network address exchange service, the network address exchange service configured to communicate the new temporary network address to wireless clients registered to access the wireless server.

8. The method of claim 6, wherein said transmitting the new temporary network address comprises transmitting an email message to an email messaging service that is configured to deliver the email message to the wireless client.

9. The method of claim 6, wherein said transmitting the new temporary network address comprises sending a short message service (SMS) message to a SMS Service Center (SMS-C) of the wireless network, the SMS-C configured to deliver the SMS message to the wireless client.

10. The method of claim 6, wherein prior to said detecting, the first temporary network address may be used by the wireless client to access the wireless server directly via the wireless network, and after said detecting the new temporary network address may be used by the wireless client to access the wireless server directly via the wireless network.
