Abstract
A communication terminal is described comprising a modem; a first memory configured to store configuration data for the modem; a second memory configured to store a system boot firmware; and a processor configured to execute the system boot firmware and to read the configuration data from the memory and provide it for the modem under the control of the system boot firmware.
Claims18
A communication terminal comprising
- a modem;
- an application processor external to the modem;
- a first memory configured to store configuration data for the modem;
- and
- a second memory configured to store a system boot firmware for the application processor,
- the application processor configured to;
- execute the system boot firmware as part of a boot service;
- while under the control of the system boot firmware, read the configuration data from the first memory and to store the configuration data in a temporary memory prior to initialization of a modem driver for the modem;
- and
- after completion of the boot service, execute the modem driver to retrieve the configuration data from the temporary memory and provide the configuration data to the modem.

A communication terminal comprising
- a modem;
- an application processor external to the modem;
- a first memory configured to store configuration data for the modem;
- and
- a second memory configured to store a firmware interface for the application processor,
- the application processor configured to:
