Embodiment Construction

[0049] figure 1 An NFC enabled device WP (eg NFC mobile phone) is shown.

[0050] The device WP comprises a device DIS comprising a contactless front element HCC, for example an NFC controller, which is responsible for wireless (non-contact) communication via the antenna ANT1 with an external RF reader RDR or an external tag or another peer NFC device. contact) communication, such as radio frequency (RF communication). The non-contact communication protocol is, for example, a protocol disclosed in ISO / IEC 14443-4.

[0051] The device also comprises a secure element SE connected to the NFC controller NCC.

[0052] A secure element is, for example, an element suitable for containing secure or protected information (eg banking information, information related to telephone subscriptions).

[0053]The secure element SE may be an embedded secure element, eg fully embedded in an integrated circuit containing an NFC controller and eg packaged with said NFC controller. In other wo...

Abstract

Disclosed is a method for managing information communication between an NFC controller (NCC) coupled to an antenna (ANT1) for a contactless communication with an object (RDR), to a device host (DH) and to at least one secure element (SE). The method comprises routing all said information through said NFC controller, communicating first information (INF1) to be communicated between said at least one secure element and said device host through a first communication link (LK1) between said NFC controller (NCC) and said device host (DH) and through a second communication link (LK2) between said NFC controller (NCC) and said at least one secure element (SE), communicating second information (INF2) coming from and / or intended to said antenna through a third communication link (LK3) between said NFC controller (NCC) and said at least one secure element (SE), said first (LK1) and second (LK2) communication links having bandwidths greater than the bandwidth of said third communication link (LK3).

Description

technical field [0001] Embodiments of the invention relate to communication between components or elements, more particularly a contactless element (e.g. an NFC ("Near Field Communication") controller element), at least one element (such as a UICC or a secure element) and, for example, a wireless Communication between device hosts within a device such as a mobile phone. Background technique [0002] In addition to the normal telephony functions of mobile phones, mobile phones can be used to exchange information with contactless devices by using contactless communication protocols. [0003] This allows information to be exchanged between the contactless device and elements located within the mobile phone. Many applications are thus possible, such as mobile ticketing (mobile phone used as ticket) or mobile payment (mobile phone used as debit / credit payment card) in public transport. [0004] Near Field Communication, or NFC, is a short-range high-frequency wireless communica...
