Embodiments of the invention concern a method for mitigating interference between near field communication and an audio stream in a mobile user equipment, wherein the method includes a step of replacing at least part of the interfered audio stream by a sound representative of an interfering near field communication transaction.

Wireless communication system and method for replacing at least part of an interference signal to mitigate interference

Embodiments of the invention concern a method for mitigating interference between near field communication and an audio stream in a mobile user equipment (), wherein the method includes a step (S) of replacing at least part of the interfered audio stream by a sound representative of an interfering near field communication transaction.

Interference mitigating method

The invention concerns a security chip of a communication device, comprising: a near field communication interface (), a first processing unit (), a first non volatile storage capability (), adapted to store first information related to near field communication, and connected to be accessed, from outside the security chip, through said near field communication interface (), under the control of said first processing unit (), wherein it also comprises a second non volatile storage capability (), adapted to store second information related to near field communication different from said first information, and connected to be accessed, from outside the security chip, independently from said first processing unit ().

Security chip of a communication device

There is described a method of, and a circuit for supplying power to an integrated circuit card, ICC, of a wireless device comprising a first power supply unit. The circuit comprises a power pin connected configured to selectively operate as a power input pin or as a power output pin, and adapted to be connected to the first power path of the device through a second power path of the device; a second power supply unit; and a controller configured to cause the power pin to operate as a power input pin in the first operation mode of the device, or as a power output pin in the second operation mode of the device. A wireless device comprising the circuit and a method of supplying power to an ICC are further disclosed.
