Abstract:
A mobile device is provided having a smart card. The smart card is powered by the mobile device and a maximum power supply value is defined by the mobile device to control the power drawn by the smart card. Provision is made for the smart card or the mobile device to renegotiate the maximum power supply level for the smart card without having to reset the mobile device. This provides the mobile device with dynamic control of the power drawn by the smart card, which can help the mobile device to optimize the power saving management.
