Abstract: In one embodiment the modem has a network interface, application interface, processor, and memory. The network interface exchanges radio data with a network. The application (or host) interface exchanges application data with an application (or host) processor. The processor converts a unit of radio data to a corresponding unit of application data. The memory stores each unit of application data received by the modem. The processor is configured to execute a selective discard function to reduce traffic by determining if a newly arrived unit of application data is a duplicate of a stored unit of application. In the case that the newly arrived unit of application data is a duplicate of the stored unit of application data, the processor is further configured to selectively discard the duplicate unit of application data in dependence on whether an acknowledgement of the data has been already recognized by the processor.

A processing unit executes the first application to provide access to the first network when the first authentication procedure has been completed, and executes the second application to provide access to the second network when the second authentication procedure has been completed. An actuation component responds to an authentication command received via a host interface to identify at least one of the first and second pieces of user authentication data to perform an authentication task in relation to the identified user authentication data.
