Abstract

A system (20) and method (50) of establishing a rapid push-to-send data exchange in a multi-wireless network environment can include a first wireless network (24 and 26) having a fast network channel to exchange an Internet Protocol (IP) address or other data, a second wireless network (23 and 27) operatively coupled to the first wireless network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer, and a communication protocol. The first wireless network can be an iDEN network and the second wireless network can be a CDMA network. The communication protocol can relinquish (66) communication using the first wireless network once a dedicated data channel on the second wireless network is established. The communication protocol can also simultaneously transfer (56) voice traffic on the first network when the first network is exchanging the IP address.

Claims

1. A method of rapid push-to-send data exchange in a multi-wireless network environment, comprising the steps of:

exchanging signals from at least a first network having a fast network channel to exchange an Internet Protocol (IP) address or other data;

switching to a second network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer;

simultaneously transferring voice traffic on the first network when the first network is exchanging the IP address;

requesting and receiving a mobile network IP address on the second network and sending the mobile network IP address on the first network from a first multimode wireless device to a second multimode wireless device; and

disconnecting from first network once the second multimode wireless device receives the mobile network IP address for the first multimode wireless device.

2. The method of claim 1, wherein the method further comprises the step of sending a request by a first multimode wireless device to send data on the second network to a second multimode wireless device.

3. The method of claim 2, wherein the method further comprises the step of receiving a mobile network IP address in response to the request to send data.

4. The method of claim 1, wherein the method further comprises the steps of establishing a data call set up between a first multimode wireless device and the second network and establishing a data call set up between a second multimode wireless device and the second network.

5. The method of claim 4, wherein a mobile network IP address of the second multimode wireless device is obtained and exchanged during the data call set up between the second multimode wireless device and the second network.

6. The method of claim 1, wherein the step of exchanging signals from at least the first network comprises the step of receiving a push-to-send request from a mobile radio to an iDEN network serving as the first network and a CDMA network serving as the second network.

7. The method of claim 1, wherein the step of exchanging signals comprises the step of sending and receiving a push-to-send request from a mobile radio to a CDMA EVDO network serving as the second network and an iDEN network serving as the first network.

8. A system of establishing a rapid push-to-send data exchange in a multi-wireless network environment, comprising:

a first wireless network having a fast network channel to exchange an Internet Protocol (IP) address or other data;

a second wireless network operatively coupled to the first wireless network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer; and

a communication protocol among an originating mobile subscriber unit, a target mobile subscriber unit, the first wireless network, and the second wireless network, wherein the first wireless network and the second wireless network receive a request for a fast paging network connection to transfer the IP address for use by the second wireless network in the wireless peer to peer data transfer, wherein the communication protocol further relinquishes communication using the first wireless network once a dedicated data channel on the second wireless network is established using the high bandwidth data channel and wherein the communication protocol simultaneously transfers voice traffic on the first network when the first network is exchanging the IP address.

9. The system of claim 8, wherein the system further comprises an optional push-to-send server operatively coupled to the first wireless network and the second wireless network that stores the IP address.

10. The system of claim 8, wherein the first wireless network is an iDEN network and the second wireless network is a CDMA network.

11. The system of claim 8, wherein the communication protocol further exchanges setup traffic between the originating mobile subscriber unit and the second network substantially in parallel to when the originating mobile subscriber unit sends a push-to-send or page request to the first network.

12. The system of claim 11, wherein the communication protocol further exchanges setup traffic between the target mobile subscriber unit and the second wireless network immediately after the first wireless network informs the target mobile subscriber of the IP address for the originating mobile subscriber unit.

13. The system of claim 8, wherein the communication protocol further receives setup traffic between the originating mobile subscriber unit and the second wireless network and between the target mobile subscriber unit and the second wireless network substantially simultaneously.

14. A mobile wireless device having a rapid push-to-send data exchange function in a multi-wireless network environment, comprising:

a first transceiver operating on a first wireless network having a fast network channel to exchange an Internet Protocol (IP) address or other data;

a second transceiver operating on a second wireless network having a high bandwidth data channel and operatively coupled to the first wireless network to exchange data using the IP address in a wireless peer to peer data transfer; and

a processor coupled to the first transceiver and the second transceiver, wherein the processor is programmed to;

exchange signals on the first network to exchange the IP address;

switch to the second network using the IP address to transfer data in the wireless peer to peer data transfer; and

simultaneously transferring voice traffic on the first network when the first network is exchanging the IP address;

wherein the mobile wireless device uses a communication protocol as an originating mobile subscriber unit or a target mobile subscriber unit in conjunction with the first wireless network and the second wireless network, wherein the first wireless network and the second wireless network receive a request for a fast raging network connection to transfer the IP address for use by the second wireless network in the wireless peer to peer data transfer, wherein the communication protocol further relinquishes communication using the first wireless network once a dedicated data channel on the second wireless network is established using the high bandwidth data channel.

15. The mobile wireless device of claim 14, wherein the data transferred on the second network is image, video, sound recording, or multimedia data.
