Abstract

A system and method for downloading information from a content server to a mobile device in communication with a wireless communication network. The mobile device is assigned a network address and registers with the content server by providing the network address as an identification information. The content server establishes a communication channel to the mobile device by opening a socket to the network address and downloads the information to the mobile device through the communication channel. If the content server cannot open a communication channel to the network address, the content server sends a message to the mobile device.

Claims

1. A method for transmitting information from a content server to a mobile device in communication with a wireless communications network, wherein the mobile device is assigned to a network address and registered with the content server, comprising the steps of:

retrieving the network address stored in the content server for the mobile device;

if the network address is valid, sending a request to open a communication channel to the network address;

if the request is successful, establishing the communication channel to the mobile device and transmitting the information to the mobile device;

if the request is unsuccessful, marking the network address as invalid; and

if the network address is invalid, sending a message to the mobile device indicating the information is available at the content server.

2. The method of claim 1, further comprising the steps of:

receiving and storing a registration request from the mobile device, wherein the registration request includes the network address; and

marking the network address received with the registration request as valid.

3. The method of claim 1, further comprising the steps of:

in response to the step of sending the message to the mobile device, receiving a download request from the mobile device; and

upon receiving the download request, downloading the information to the mobile device.

4. The method of claim 1, wherein the message is an SMS message.

5. The method of claim 1, wherein the step of sending the request to open a communication channel to the network address further comprises the step of opening a socket to the network address.

6. The method of claim 1, wherein the network address is an IP address.

7. The method of claim 1, further comprising the step of, if the request is unsuccessful, receiving a failure message.

8. The method of claim 1, wherein the wireless communications network is a GSM network.

9. A method for establishing a communication channel between a content server and a mobile device in communication with a wireless communications network, wherein the mobile device is registered with a gateway server, comprising the steps of:

receiving a registration request from the mobile device at the gateway server;

in response to the registration request, assigning a network address to the mobile device;

storing the assigned network address in the gateway server;

receiving a communication channel request from the content server directed to the network address;

retrieving the network address upon receiving the communication channel request;

forwarding the communication channel request to the mobile device;

if the mobile device acknowledges the communication channel request, sending an acknowledgement to the content server and establishing a communication channel between the mobile device and the content server; and

if the mobile device does not acknowledge the communication channel request, sending a failure message to the content server.

10. The method of claim 9, further comprising the step of receiving an acknowledgement from the mobile device acknowledging the communication channel request.

11. The method of claim 9, wherein the communication channel request is an open socket request.

12. The method of claim 9, wherein the content server is an email server.

receiving a failure message from the content server indicating the communication channel request has failed; and

closing the communication channel to the mobile device.

17. The method of claim 9, further comprising the steps of:

receiving a content from the content server; and

transmitting the content received from the content server to the mobile device.

18. A method for a mobile device to receive information from a content server, the mobile device being in communication with a wireless communications network, comprising the steps of:

sending a first registration request to a gateway server;

in response to sending the first registration request, receiving a network address from the gateway server;

after receiving the network address, sending a second registration request to a content server;

after registering with the content server, receiving an open communications channel request from the gateway server;

in response to receiving the open communications channel sending an acknowledgement to the gateway server; and

after sending the acknowledgement to the gateway server, receiving the information from the content server.

19. The method of claim 18, wherein the step of sending the first registration request further comprises the step of sending identification information to the gateway server, wherein the identification information includes a mobile identification number.

20. The method of claim 18, wherein the step of sending the second registration request further comprises the steps of:

opening a socket to the content server;

after opening the socket, providing the network address to the content server; and

after providing the network address to the content server, closing the socket to the content server.

21. The method of claim 18, further comprising the step of sending a SMS message to the content server.

22. The method of claim 18, wherein the network address is an IP address.

23. A method for delivering a message to a mobile terminal from a message server, the mobile terminal and message server operating as part of a wireless communication network, the method comprising the steps of:

at the mobile terminal;

sending a packet data protocol context request;

receiving a response to the packet data protocol context request, the response including context data with a packet data protocol address assigned to the mobile terminal;

opening a first socket connection between the mobile terminal and the message server to convey the packet data protocol address;

closing the first socket connection after conveying the packet data protocol address; and

maintaining active at least part of the context data received in response to the packet data protocol context request;

at the message server;

obtaining the packet data protocol address for the mobile terminal conveyed with the first socket connection between the mobile terminal and the message server;

storing the packet data protocol address as being associated with the mobile terminal independent of any socket connection with the mobile terminal;

obtaining a message destined for the mobile terminal after the first socket connection is closed;

when the stored packet data protocol address is valid for the mobile terminal,

opening a second socket connection with the mobile terminal in response to receipt of the message, using the stored packet data protocol address; and

transmitting the message to the mobile terminal using the second socket connection.

24. The method of claim 23, further comprising the steps of,

at the message server:

when there is no stored packet data protocol address that is valid for the mobile terminal, transmitting a short message service message to the mobile device notifying the mobile device of an available message; and

transmitting the message to the mobile terminal on demand from the mobile device.
