Abstract
A wireless device may establish a data connection with a 2G or 3G wireless network, which the wireless device can then use to engage in packet data communications with other devices on packet data networks. The wireless device may then roam from one wireless network to the other wireless network, such by roaming from the 2G wireless network to the 3G wireless network or vice versa. The wireless device may then transfer its data connection between the networks, thereby allowing the wireless device to continue in any established data sessions with other devices.
