Radio frequency identification (RF-ID) based discovery for short range radio communication with reader device having transponder functionality
First Claim
1. A method, comprising:
- a) generating a RF-ID interrogation signal by a first terminal equipped with a RF-ID tag reader device;
b) detecting the RF-ID interrogation signal by a second terminal when within the range of the RF-ID interrogation signal;
c) in response to detecting the presence of the RF-ID interrogation signal, providing a notification to activate a processor in the second terminal, the processor using the notification for setting a short-range communication module in the second terminal into a page scanning mode for detecting paging signals directed to the second terminal;
d) responding to the RF-ID interrogation signal by transmitting a RF-ID response signal to the first terminal including identification information relating to the short-range communication module of the second terminal;
e) processing the received RF-ID response signal by the first terminal to activate a short-range communication module in the first terminal to initiate a shortened session setup by skipping the inquiry stage;
transmitting a short-range paging signal directed to the second terminal based on information of the received RF-ID response signal and entering a page mode to establish a short-range connection with the second terminal; and
f) detecting the paging signal by the short-range communication module in the second terminal for immediate establishment of a short-range connection between the first and second terminals by skipping the inquiry stage.

Abstract
A RF-ID based wireless terminal includes a reader device with transponder functionality implementing ECMA 340 standard for near field communication and has shortened session set-up and user identification. The reader device is operable in an active communication mode or a passive communication mode. During the active mode, one RF-ID tag reader simulates a RF-ID tag while the other simulates a RF-ID tag reader. The reader includes a transponder, which operates during periods of time when the reader is not energized. A radio frequency interface provides signal for operation of the reader in the reader operation mode or transponder mode of operation. An RF-ID reader upon receiving a response signal from a semi-passive or active RF-ID tag of reader emulating a tag informs the terminal CPU which instructs the short-range communication to enter e.g. a page scanning mode which shortens session set-up time and user identification.
