For example, a first peer-to-peer device may set a waiting timer to count a waiting period during a connection session setup of a session with a second peer-to-peer device; and during the waiting period, check whether the second peer-to-peer device is in the connection session setup by transmitting a probe request to the second peer-to-peer device, the probe request including an Information (Info) attribute. ## Claims ### Claim 1 An apparatus comprising circuitry and logic configured to cause a first peer-to-peer device to: set a waiting timer to count a waiting period during a connection session setup of a session with a second peer-to-peer device; and during the waiting period, check whether the second peer-to-peer device is in said connection session setup by transmitting a probe request to the second peer-to-peer device, the probe request comprising an Information (Info) attribute. ### Claim 2 (depends on 1) The apparatus of claim 1 configured to allow the first peer-to-peer device to determine a failure of the connection session setup and stop the waiting timer during the waiting period, if a probe response, which comprises the Info attribute, is not received from the second peer-to-peer device. ### Claim 3 (depends on 1) The apparatus of claim 1 configured to cause the first peer-to-peer device to retransmit the probe request during the waiting period, if a probe response, which comprises the Info attribute, is not received from the second peer-to-peer device. ### Claim 4 (depends on 1) The apparatus of claim 1 configured to allow the first peer-to-peer device to determine the failure of the connection session setup and stop the waiting timer during the waiting period, if no probe response is received from the second peer-to-peer device. ### Claim 5 (depends on 1) The apparatus of claim 1 configured to allow the first peer-to-peer device to determine the failure of the connection session setup and stop the waiting timer during the waiting period, if a probe response, which does not include the Info attribute, is received from the second peer-to-peer device. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the Info attribute comprises a Session Identifier (ID) Info attribute. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the Session ID Info attribute comprises a Session ID field comprising a value of a session ID, and a session Media Access Control (MAC) address field comprising a peer-to-peer device address. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein a combination of the session ID and the peer-to-peer device address is to uniquely identify said session. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the session MAC address field comprises a peer-to-peer device address of a peer-to-peer device, by which the session ID is as signed. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the session comprises an Application Service Platform (ASP) session between a first ASP of the first peer-to-peer device and a second ASP of the second peer-to-peer device. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the waiting timer comprises a 120 second timer. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein the probe request comprises a unicast frame individually addressed to the second peer-to-peer device. ### Claim 13 (depends on 1) The apparatus of claim 1 comprising a radio. ### Claim 14 (depends on 1) The apparatus of claim 1 comprising one or more antennas, a memory and a processor. ### Claim 15 An apparatus comprising circuitry and logic configured to cause a first peer-to-peer device to: set a waiting timer to count a waiting period during a connection session setup of a session with a second peer-to-peer device; and during the waiting period, upon receipt of a probe request from the second peer-to-peer device comprising an Information (Info) attribute, transmit to the second peer-to-peer device a probe response, which comprises the Info attribute, when the first peer-to-peer device is still in the connection session setup. ### Claim 16 (depends on 15) The apparatus of claim 15 configured to cause the first peer-to-peer device to, in response to the probe request, transmit to the second peer-to-peer device a probe response, which does not comprise the Info attribute, when the first peer-to-peer device is not in the connection session setup. ### Claim 17 (depends on 15) The apparatus of claim 15 configured to cause the first peer-to-peer device to, in response to the probe request, select not to transmit the probe response, when the first peer-to-peer device is not in the connection session setup. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the Info attribute comprises a Session Identifier (ID) Info attribute. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the Session ID Info attribute comprises a Session ID field comprising a value of a session ID, and a session Media Access Control (MAC) address field comprising a peer-to-peer device address. ### Claim 20 (depends on 15) The apparatus of claim 15, wherein the session comprises an Application Service Platform (ASP) session between a first ASP of the first peer-to-peer device and a second ASP of the second peer-to-peer device. ### Claim 21 (depends on 15) The apparatus of claim 15 comprising one or more antennas, a memory and a processor. ### Claim 22 A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement operations at a first peer-to-peer device, the operations comprising: generating a probe request comprising a Session Identifier (ID) Information (Info) attribute; and transmitting the probe request to a second peer-to-peer device during a connection session setup of a session with the second peer-to-peer device. ### Claim 23 (depends on 22) The product of claim 22, wherein the Session ID Info attribute comprises a Session ID field comprising a value of a session ID, and a session Media Access Control (MAC) address field comprising a peer-to-peer device address. ### Claim 24 A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement operations at a first peer-to-peer device, the operations comprising: processing a probe request received from a second peer-to-peer device during a connection session setup of a session with the second peer-to-peer device, the probe request comprising a Session Identifier (ID) Information (Info) attribute; and transmitting a probe response to the second peer-to-peer device in response to the probe request. ### Claim 25 (depends on 24) The product of claim 24, wherein the session comprises an Application Service Platform (ASP) session between a first ASP of the first peer-to-peer device and a second ASP of the second peer-to-peer device.
