A method and apparatus for selecting a data connection IP (Internet Protocol) type during roaming. At a device a comprising a processor, a memory storing data indicative of radio access technologies and associated internet protocol (IP) types to use under different roaming conditions, and a communication interface, it is determined, using the communication interface, that roaming is occurring and a given radio access technology being used in the roaming is also determined. The data is processed to select an IP type associated with the given radio access technology. Thereafter, the IP type selected is used, during the roaming, in requests to a gateway to a network.

Method and apparatus for selecting an IP type during roaming

Described are systems and methods for managing data transfer from a communication device to a communication network over a wireless connection comprising determining that a requesting process on the communication device is authorized to establish a protected connection to the communication network; and, configuring a network interface on the communication device to allow data packets to be transmitted from the requesting process to the communication network over the protected connection, wherein the network interface is associated with the protected connection.
