FIELD: radio engineering, communication.SUBSTANCE: invention relates to wireless communication systems and describes an improved mechanism for updating parameters for communication between a device host (DH) and a remote NFC endpoint. A DH connected to a NFC device may be configured to determine that one or more parameters included in a parameter selection request message are different from one or more corresponding parameters used when detecting a remote NFC endpoint, using a frame RF interface, and transmit the parameters to a NFC controller using a parameter update message. A NFCC connected to the NFC device may be configured to receive, using a NFC-DEP interface, a parameter selection request message which includes one or more parameters, determine the need to make one or more changes to the parameters based on the received one or more parameters and transmit an activation message to the DH, indicating the values to which the NFC controller changed one or more parameters.EFFECT: improved mechanism for updating parameters for communication between a device host (DH) and a remote NFC endpoint.56 cl, 13 dwg |
