Assignee: CSL DUALCOM LIMITED
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC H

Claim 0:
1. A universal integrated circuit card (UICC) for controlling radio communications via a radio communications network to and from a host device in which the UICC is installed in use, the UICC comprising:
a microprocessor for controlling the operation of the UICC;
a data store for storing data relating to the operation of the UICC, the data store comprising:
a plurality of mobile operator network profiles including:
an operational profile comprising radio communications network settings for connecting the host device to a first radio communications network; and
a bootstrap profile comprising radio communications network settings for connecting the host device to a second radio communications network; and
a program comprising a plurality of instructions for configuring operation of the UICC;
wherein, in use, the microprocessor is configured by the program to:
use the operational profile to connect the host device to the first radio communications network;
detect a loss of operational connectivity with the first radio communications network; and
use the bootstrap profile to connect the host device to the second radio communications network to re-establish radio communications to and from the host device;
start a cancellation timer, for a predetermined time period when a loss of connection on the first network has been detected; and
deselect the bootstrap profile and re-select the operational profile once the cancellation timer is completed, and use the operational profile to re-connect to the first radio communications network in order to re-establish radio communications network connectivity between the host device and the first radio communications network.
