Method for near field communication operation, a device and a system thereto

摘要

A method, a user terminal and a system for performing a NFC operation by a NFC equipped user terminal. According to a method a common application residing in a secure element of the user terminal can be authenticated by receiving, in the common application, an authentication request message including identification information on at least service provider of the NFC reader. Based on the identification information authentication related data on a service provider of NFC service is retrieved from a database. Furthermore, a data request message is received from the NFC reader. The data is retrieved, on the basis of identification information on at least service provider of the NFC reader and identification information for data, from the database residing in the secure element of the user terminal. The data requested is delivered to the NFC reader.

主权项

1. A method for performing a Near Field Communication (NFC) operation by an NFC-equipped user terminal communicating with an NFC reader, the method comprising:
obtaining data from a database by
receiving a data request message, in a common application residing in a secure element of the NFC-equipped user terminal, from the NFC reader, the data request message comprising identification information of at least a service provider of the NFC reader and identification information for data to be retrieved from the database residing in the secure element of the NFC-equipped user terminal, the secure element being implemented on an integrated circuit card provided by a telecom operator, anddelivering a response message comprising the requested data, the data being retrieved by the common application from the database based on the identification information of the service provider of the NFC reader and the identification information for data to be retrieved from the database residing in the secure element of the user terminal; and encrypting the data request message from the NFC reader and the delivered response message by an encryption method and at least one encryption key, wherein the NFC reader of the service provider is configured to initiate communication with the NFC-equipped user terminal in response to detecting the NFC-equipped user terminal in the vicinity of the NFC reader, the vicinity being below an activation distance of the NFC operation.
