Abstract

In an example embodiment, a method includes determining, by an apparatus, whether the apparatus provides data for other wireless devices to request from the apparatus in response to wireless device discovery messages transmitted by the apparatus; and transmitting, by the apparatus, wireless device discovery messages including an indication that additional information should not be requested from the apparatus in response to the wireless device discovery messages, without establishing a connection with the apparatus, the indication being in response to the determination that the apparatus does not provide data for other wireless devices to request from the apparatus in response to the wireless device discovery messages.

First claim

What is claimed is:

1 . A method, comprising:
determining, by an apparatus, whether the apparatus provides data for other wireless devices to request from the apparatus in response to wireless device discovery messages transmitted by the apparatus; and transmitting, by the apparatus, wireless device discovery messages including an indication that additional information should not be requested from the apparatus in response to the wireless device discovery messages, without establishing a connection with the apparatus, the indication being in response to the determination that the apparatus does not provide data for other wireless devices to request from the apparatus in response to the wireless device discovery messages.

2 . The method of claim 1 , wherein the apparatus includes information in an advertising channel packet header, to inform other wireless devices that requests for information from the apparatus, shall not be transmitted in response to the wireless device discovery messages.

3 . The method of claim 1 , wherein the wireless device discovery messages are advertising packets that inform scanning wireless devices that the scanning wireless devices shall not transmit an information request packet in response to the advertising packets, without establishing a connection with the apparatus.

4 . The method of claim 1 , wherein the wireless device discovery messages are Bluetooth™ Low Energy advertising packets, which use four bits in a Packet Data Unit type (PDU type) field of an advertising channel PDU header, to indicate to scanning wireless devices a need to comply with a rule as to whether the scanning wireless devices are allowed to transmit a Bluetooth™ Low Energy SCAN_REQ packet in response to the advertising packets.

5 . The method of claim 1 , further comprising:
altering, by the apparatus, the indication that additional information should not be requested from the apparatus, if the apparatus has available information for scanning wireless devices, the alteration including allowing scanning wireless devices to transmit requests for information from the apparatus, on a schedule specified by the apparatus in the wireless device discovery messages.

6 . The method of claim 1 , further comprising:
altering, by the apparatus, the indication that additional information should not be requested from the apparatus, in response to the apparatus determining a number of received information requests or CRC failures.

7 . A method, comprising:
receiving, by an apparatus, wireless device discovery messages from a wireless device, including an indication that additional information should not be requested from the wireless device in response to the wireless device discovery messages, without establishing a connection with the wireless device; and refraining, by the apparatus, from transmitting information request messages to the wireless device, in response to receiving the wireless device discovery messages, if the apparatus does not wish to establish a connection with the wireless device, in response to the wireless device discovery messages.

8 . The method of claim 7 , further comprising:
transmitting, by the apparatus, one or more wireless connection request messages to the wireless device, if the apparatus wishes to establish a connection with the wireless device, in response to the wireless device discovery messages.

9 . The method of claim 7 , wherein the wireless device discovery messages are Bluetooth™ Low Energy advertising packets, which use four bits in a Packet Data Unit type (PDU type) field of an advertising channel PDU header, to indicate to scanning wireless devices a need to comply with a rule as to whether the scanning wireless devices are allowed to transmit a Bluetooth™ Low Energy SCAN_REQ packet in response to the advertising packets.

10 . The method of claim 7 , further comprising:
transmitting, by the apparatus, requests for information to the wireless device, on a schedule specified by the wireless device in the wireless device discovery messages.

11 . An apparatus, comprising:
at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine whether the apparatus provides data for other wireless devices to request from the apparatus in response to wireless device discovery messages transmitted by the apparatus; and transmit wireless device discovery messages including an indication that additional information should not be requested from the apparatus in response to the wireless device discovery messages, without establishing a connection with the apparatus, the indication being in response to the determination that the apparatus does not provide data for other wireless devices to request from the apparatus in response to the wireless device discovery messages.

12 . The apparatus of claim 11 , wherein the apparatus includes information in an advertising channel packet header, to inform other wireless devices that requests for information from the apparatus, shall not be transmitted in response to the wireless device discovery messages.

13 . The apparatus of claim 11 , wherein the wireless device discovery messages are advertising packets that inform scanning wireless devices that the scanning wireless devices shall not transmit an information request packet in response to the advertising packets, without establishing a connection with the apparatus.

14 . The apparatus of claim 11 , wherein the wireless device discovery messages are Bluetooth™ Low Energy advertising packets, which use four bits in a Packet Data Unit type (PDU type) field of an advertising channel PDU header, to indicate to scanning wireless devices a need to comply with a rule as to whether the scanning wireless devices are allowed to transmit a Bluetooth™ Low Energy SCAN_REQ packet in response to the advertising packets.

15 . The apparatus of claim 11 , further comprising:
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: alter the indication that additional information should not be requested from the apparatus, if the apparatus has available information for scanning wireless devices, the alteration including allowing scanning wireless devices to transmit requests for information from the apparatus, on a schedule specified by the apparatus in the wireless device discovery messages.

16 . The apparatus of claim 11 , further comprising:
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: alter the indication that additional information should not be requested from the apparatus, in response to the apparatus determining a number of received information requests or CRC failures.

17 . An apparatus, comprising:
at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive wireless device discovery messages from a wireless device, including an indication that additional information should not be requested from the wireless device in response to the wireless device discovery messages, without establishing a connection with the wireless device; and refrain from transmitting information request messages to the wireless device, in response to receiving the wireless devi
