Abstract

A system and method establishes a data session between a mobile device and a destination server. A radio traffic channel is established between the mobile device and a radio network. At least partially simultaneous to establishing the radio traffic channel, the radio network establishes a connection between the mobile device and the destination server.

Claims

1. A method for establishing a data session between a mobile device and a destination server comprising:

establishing a radio traffic channel between the mobile device and a radio network; and

at least partially simultaneous to establishing the radio traffic channel, establishing, by the radio network, a connection between the mobile device and the destination server.

2. The method of claim 1, wherein establishing the radio traffic channel between the mobile device and the radio network and establishing the connection between the mobile device and the destination server are initiated by a first message.

3. The method of claim 2, wherein sending the first message comprises sending an initiation message to the radio network, the initiation message comprising radio network information used to establish the radio traffic channel between the mobile device and the radio network, and protocol information used by the radio network to establish the connection between the mobile device and the destination server.

4. The method of claim 3 wherein establishing the connection comprises:

establishing, by the radio network, a first connection between the radio network and the destination server using the protocol information;

establishing, by the radio network, a second connection between the radio network and the mobile unit using the protocol information;

establishing, by the radio network, a third connection between the mobile unit and the destination server by utilizing the first and second connections; and

terminating, by the radio network, the first and second connections upon the establishment of the third connection.

5. The method of claim 3 wherein sending the initiation message to the radio network comprises sending a message selected from a group comprising a Reconnect message, a Data Burst Message, and a Short Data Burst Message.

6. The method of claim 5 wherein the protocol information comprises high level protocol information and low level protocol information.

7. The method of claim 6, wherein the high level protocol information includes information selected from a group of information comprising:

Hyper Text Transfer Protocol (HTTP) information, File Transfer Protocol (FTP) information, Session Initiation Protocol (SIP) information, Simple Mail Transfer Protocol (SMTP) information, Post Office Protocol (POP) information, and Intermediate Message Access Protocol (IMAP) information.

8. The method of claim 6 wherein the low-level protocol information comprises protocol ID, a source port number, and a destination port number.

9. The method of claim 1, wherein establishing the connection between the mobile device and the destination server comprises determining, by the radio network, a destination address corresponding to the destination server.

10. The method of claim 1 wherein establishing a radio traffic channel is performed in a network chosen from a group comprised of a code division multiple access (CDMA)-2000 network, Universal Mobile Telecommunications System (UMTS) network, a General packet Radio System (GPRS) network, and a satellite network.

11. A proxy device in a radio network for facilitating a connection between a destination server and a mobile device on a radio network comprising:

a receiver for receiving an initiation message, the initiation message comprising protocol information; and

a processor, the processor coupled to the receiver and receiving the protocol information and initiating connection and resolution messages with the destination server and, responsively, receiving messages from the destination server, the connection and resolution messages being sent and received to and from the destination server at least partially simultaneous with radio channel establishment on the radio network.

12. The proxy device of claim 11 wherein the initiation message comprises a message selected from a group of messages comprising a Reconnect message, a Data Burst Message, and a Short Data Burst message.

13. The proxy device if claim 11 wherein the radio network is chosen from a group comprised of a code division multiple access (CDMA)-2000 network, a Universal Mobile Telecommunications System (UMTS) network, a General Packet Radio System (GPRS) network, and a satellite network.

14. The proxy device of claim 11 wherein the processor comprises means for reverting to a passive mode once the radio channel establishment is completed.

15. The proxy device of claim 11 wherein the connection and resolution messages are used for DNS resolution and TCP connection establishment.

16. The proxy device of claim 11 wherein the protocol information comprises information indicating a high-level protocol information and a low-level protocol information.

17. A system for establishing a data session between a destination server and a mobile device comprising:

a destination server;

a proxy device in a radio network, the proxy device coupled to the destination server;

the radio network establishing a traffic channel with the destination server, the proxy device receiving an initiation message from the radio network, the initiation message including protocol information, the proxy device initiating connection and resolution messages with the server and, responsively, receiving messages from the destination server, the messages being sent and received from the destination server at least partially simultaneous with radio channel establishment on the radio network.

18. The system of claim 17 wherein the initiation message is a message selected from a group comprising a Reconnect message, a Data Burst message, and a Short Data Burst message.

19. The system of claim 17 wherein the network is chosen from a group comprised of a code division multiple access (CDMA)-2000 network, a Universal Mobile Telecommunications System (UMTS) network, a General Packet Radio System (GPRS) network, and a satellite network.

20. The system of claim 17 wherein the proxy device includes means for reverting to a passive mode once the radio channel is established on the radio network.

21. The system of claim 17 wherein the connection and resolution messages exchanged between the proxy device and the server are used for DNS resolution and TCP connection establishment.
