Abstract

A method and device for adapting a communication from a mobile terminal equipped with a near-field communication module. The mobile terminal is able to be placed in NFC mode or in IBC mode to carry out contactless transactions. It is able to receive a message in an electromagnetic field over a near-field channel. The method includes, on the mobile terminal, the following steps: receiving, from a terminal placed in read mode, called the reader terminal, a message inviting to open communications according to a type of near-field communication; detecting a type of near-field communication in the received invitation message; if the type of communication indicates an IBC communication, and the mobile terminal is placed in IBC mode, sending a pairing request over a return channel distinct from the near-field channel.

Claims (35)

1 . A method for adapting a communication of a mobile terminal equipped with a near-field communication (NFC) module, said mobile terminal being able to be set to an NFC mode or to an IBC (Intra-Body Communication) mode in order to carry out contactless transactions, and to receive a message in an electromagnetic field over a near-field channel, the method being implemented on the mobile terminal and comprising:

receiving, from a reader terminal, an invitation message inviting communications alternately according to types of near-field communication;

and

transmitting, in response to said invitation message indicating an IBC communication, and the mobile terminal being set to IBC mode, a pairing request over a return channel distinct from the near-field channel.

2 . The method for adapting the communication of a mobile terminal as claimed in claim 1 , wherein the method further comprises:

transmitting a command to switch to IBC mode to the near-field communication module.

3 . The method for adapting the communication of a mobile terminal as claimed in claim 1 , wherein transmitting a pairing request over a return channel is followed by:

establishing a two-way communication with the reader terminal over the return channel.

4 . The method as claimed in claim 1 , wherein said invitation message contains a random datum for establishing the return channel.

5 . The method as claimed in claim 1 , wherein said invitation message contains a type of IBC application.

6 . The method as claimed in claim 1 , wherein said invitation message is received during an ISO (International Standard Organization) 14443 type communication.

7 . The method as claimed in claim 1 , wherein the type of IBC communication is indicated in a field of the invitation message left empty by an NFC standard for a future use.

8 . The method as claimed in claim 1 , wherein the type of IBC communication is indicated in a field of the invitation message defined by an NFC standard for a proprietary application.

9 . A device for adapting a communication of a mobile terminal equipped with a near-field communication (NFC) module, said device being adapted to set the mobile terminal to an NFC mode or to an IBC (Intra-Body Communication) mode in order to carry out contactless transactions, so as to receive a message in an electromagnetic field, wherein the device comprises:

a processor and a non-transitory computer readable medium comprising instructions stored thereon which when executed by the processor configure the device to implement the following on the mobile terminal:

receiving, from a reader terminal, an invitation message inviting communications alternately according to types of near-field communication;

and

transmitting, in response to said invitation message indicating an IBC communication, and the mobile terminal being set to an IBC mode, a pairing request over a return channel distinct from the near-field channel.

10 . A method for inviting communications on a terminal, called reader terminal, of an NFC (near-field communication) type, said reader terminal being adapted to invite according to at least one NFC type near-field communication and one IBC (Intra-Body Communication) type near-field communication, the method comprising, on the reader terminal set to NFC reader mode so as to transmit a message in an electromagnetic field:

transmitting, to a mobile terminal, an invitation message inviting communications alternately according to types of near-field communication; and

receiving, in response to said invitation message indicating an IBC communication and the mobile terminal being in IBC mode, a pairing message over a return channel distinct from the near-field channel.

11 . The method for inviting communications on a reader terminal as claimed in claim 10 , wherein inviting according to at least one NFC type near-field communication and one IBC type near-field communication comprises the following sub-steps, repeated cyclically:

transmitting invitation messages to the mobile terminal according to an NFC type communication, according to a standardized NFC polling mechanism; and

transmitting an invitation message to the mobile terminal according to an IBC type communication.

12 . A device for inviting communications on a reader terminal equipped with a near-field communication (NFC) module, said device being adapted to set the reader terminal to NFC reader mode so as to transmit a message in an electromagnetic field, and to invite communications according to at least one NFC type near-field communication and one IBC (Intra-Body Communication) type near-field communication, wherein the device comprises:

transmitting an invitation message inviting communications alternately according to types of near-field communication to a mobile terminal; and

13 . A non-transitory computer readable medium comprising a computer program stored thereon and able to be implemented on a mobile terminal, the program comprising code instructions which, when the program is executed by a processor of the mobile terminal, carries out a method for adapting a communication of the mobile terminal, wherein the mobile terminal is equipped with an NFC (near-field communication) module, said mobile terminal being able to be set to an NFC mode or to an IBC (Intra-Body Communication) mode in order to carry out contactless transactions, and to receive a message in an electromagnetic field over a near-field channel, the method comprising:

receiving, from a reader terminal, an invitation message inviting communications alternately according to types of near-field communication;

and

14 . A non-transitory computer readable medium comprising a computer program stored thereon and able to be implemented on a reader terminal, the program comprising code instructions which, when the program is executed by a processor of the reader terminal, carries out a method for inviting communications on the reader terminal, of an NFC (near-field communication) type, said reader terminal being adapted to invite according to at least one NFC type near-field communication and one IBC (Intra-Body Communication) type near-field communication, the method comprising, on the reader terminal set to NFC reader mode so as to transmit a message in an electromagnetic field:

transmitting, to a mobile terminal, an invitation message inviting communications alternately according to types of near-field communication; and
