Abstract
A method, software tool, computer program product and low power radio device are provided for transponder aided wake-up and connection set-up by detecting a wake up event in a sleep mode of the low power radio device, putting the radio device into an operative state, transmitting at least one advert message by radio transmission, wherein the low power radio devices put into a passive mode for a predetermined period of time in case no answer is received in response to the at least one transmitted advert message.

22. Method in a communication comprising:
-
detecting a wake up event through a radio frequency sensor interface of low power radio device, putting said radio device into an operative state including powering a radio frequency communication interface in response to detection of said wake up event, transmitting at least one advertising message via the radio frequency communication interface, determining whether a response to said at least one advertising message is received through the radio frequency communication interface; and
putting said low power radio device into a passive operation mode for a predetermined period of time, in the passive operation mode including shutting down the radio frequency communication interface, if it is determined that no response to said at least one transmitted advertising message is received, and ignoring subsequent wake up events detected during said predetermined period of time of passive operation mode so as to avoid using power to put said radio device into said operative state to transmit another advertising message via the radio frequency communication interface during said predetermined period of time of passive mode operation. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 34)

33. Computer program product comprising program code, downloadable from a server for carrying out a method for transponder aided wake up and connection set up when said program product is run on a computer by carrying out:
-
detecting a wake up event through a radio frequency sensor interface of said low power radio device, putting said radio device into an operative state including powering a radio frequency communication interface in response to detection of said wake up event, transmitting at least one advertising message via the radio frequency communication interface, determining whether a response to said at least one advertising message is received through the radio frequency communication interface, and putting said low power radio device into a passive operation mode for a predetermined period of time, in the passive operation mode including shutting down the radio frequency communication interface, if it is determined that no response to said at least one transmitted advertising message is received, and ignoring subsequent wake up events detected during said predetermined period of time of passive operation mode so as to avoid using power to put said radio device into said operative state to transmit another advertising message via the radio frequency communication interface during said predetermined period of time of passive mode operation.

35. Apparatus comprising:
-
a transponder adapted to respond to received radio transmission for setting up a radio connection for transmitting data, said transponder comprising;
a transceiver adapted to transmit and receive data and a transponder controller connected to said transceiver, a state controller adapted to control the operative state of said apparatus, said state controller comprising;
a detector adapted to detect a wake up event in a sleep mode of said apparatus and to notify said state controller to put said apparatus into an operative state if a wake up event is detected, wherein said state controller is connected to said transponder and is adapted to put said apparatus to a sleep mode, according to signals received from said transponder, wherein said state controller further comprises a timer, said timer being adapted to be active for a predetermined period of time, wherein said timer is adapted to be activated by said state controller when the apparatus is put to a passive mode, and said state controller is adapted to be inactive while said timer is active so as to avoid said transponder responding to said received radio transmission while in said passive mode. - View Dependent Claims (36, 37, 38, 39, 40, 41)

42. Apparatus comprising:
-
transponder means adapted to respond to received radio transmission for setting up a radio connection for transmitting data, said transponder means comprising;
transceiver means adapted to transmit and receive data and a transponder controller means connected to said transceiver means, state controller means adapted to control the operative state of said apparatus, said state controller means comprising;
detector means adapted to detect a wake up event in a sleep mode of said apparatus and to notify said state controller means to put said apparatus into an operative state if a wake up event is detected, wherein said state controller means is connected to said transponder means and is adapted to put said apparatus to a sleep mode, according to signals received from said transponder means, wherein said state controller means further comprises timer means, said timer means being adapted to be active for a predetermined period of time, wherein said timer means is adapted to be activated by said state controller means when the apparatus is put to a passive mode, and said state controller means is adapted to be inactive while said timer means is active so as to avoid said transponder responding to said received radio transmission while in said passive mode.
