Embodiment approach 1
[0094] Embodiment 1 - In the case of a new P2P connection
[0095] In the case where the advertiser device is configured to defer a session request during new P2P connection establishment, a process of transmitting information on the deferred session to the seeker device will be described below as an embodiment applied to the present invention.
[0096] Figure 7 is a flowchart showing an example of a session deferred establishment procedure according to an embodiment of the present invention.
[0097] Such as Figure 7 As shown in , when device A (first device) is a service advertiser and device B (second device) is a service seeker, device A as an advertiser can call the AdvertiseService method and send a service that can thereby be offered to its ASP (S702). During a call to the AdvertiseService method, session deferred establishment means the case of auto_accept=false, which indicates a state in which session requests are not automatically accepted.
[0098] Device B a...
Embodiment approach 1-1
[0100] Implementation Mode 1-1: Session Delay Establishment During AdvertiseService Method Call
[0101] First, the procedure of setting up a session deferral by an advertiser device will now be described.
[0102] The advertiser device may transmit information about the service advertised by the advertiser device to the ASP (S702), and then receive a discovery request (then receive a probe request frame) from the seeker device. That is, the advertiser device can perform service advertisement with respect to the ASP through the AdvertiseService method.
[0103] The AdvertiseService method provides information so that a service seeker can search for a service advertised on another device and start an ASP session. The AdvertiseService method is as follows.
[0104] AdvertiseService(service_name, auto_accept, service_information, service_status, session_information_response)

Embodiment approach 1-2
[0113] Embodiment 1-2: Provisioning Discovery Request / Response
[0114] Before the seeker device discovers the advertiser device, the seeker device can call the above-mentioned AdvertiseService method to discover the devices in the process of sending and receiving probe discovery request / response frames (S706 and S708), and then send the service discovery request after sending and receiving / WFDS service to be used in the process of responding to the frame (S710 and S712). Thereafter, provisioning discovery request / response frames are sent and received during service session request / response. Now, a method for transmitting session postponement information will be described in detail.
[0115] The provisioning discovery process is mandatory before establishing a P2P connection for an ASP session. The main purpose of this process is to ensure the network function of each device and to decide various parameters such as the working channel. The provisioning discovery process...
