CONTACTLESS RECHARGING OF MOBILE TERMINAL BATTERY
First Claim
Patent Images
1. A method of recharging a battery through a contactless function (CLF) module of a mobile terminal, comprising:
- checking, by the CLF module, a power supply for the mobile terminal;
detecting, by the CLF, a radio frequency (RF) field when no power supply is detected by the checking step;
activating a secure element to detect whether any transaction is requested; and
transferring the power inducted by the radio frequency (RF) field to the battery for recharging when no transaction is ongoing.

Abstract
A mobile terminal has a contactless function module that is used to perform a contactless transaction and also used to perform battery recharging, and a power source operatively connected with the contactless function module and adapted to be recharged by induced current created by electromagnetic fields detected by the contactless function module.

6. A method of controlling a wireless function module of a mobile terminal, comprising:
-
detecting an electromagnetic field; and performing at least one of a transaction with another terminal using the detected electromagnetic field and battery recharging as a lower priority compared with the transaction. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of controlling a wireless function module, comprising:
-
detecting whether electromagnetic fields are present; performing both battery recharging and transactions with another device, if the detected electromagnetic fields are sufficient to support both operations; and performing battery recharging as a lower priority compared with the transactions that are a higher priority, if the detected electromagnetic fields are insufficient to support the transactions. - View Dependent Claims (13, 14, 15)
