Communication apparatus, method of controlling the same, and non-transitory computer-readable storage medium

A method of controlling a communication apparatus, comprising:

• in a first period which is a Discovery Window defined in Neighbor Awareness Networking (NAN), in a case when a signal for searching for a predetermined service or a reply corresponding to the signal is communicated with another communication apparatus, determining whether there is a communication parameter that was shared with the other communication apparatus;
• in a case when it is determined that there is a communication parameter shared with the other communication apparatus, using the shared communication parameter to establish a data link with the other communication apparatus;
• and
• in a second period including a period different to the first period, executing the predetermined service by a data link established by the data link control unit.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of a communication apparatus, the method comprising:

• in a first period which is a Discovery Window defined in Neighbor Awareness Networking (NAN), in a case when a signal for searching for a predetermined service or a reply corresponding to the signal is communicated with another communication apparatus, determining whether there is a communication parameter that was shared with the other communication apparatus;
• in a case when it is determined that there is a communication parameter shared with the other communication apparatus, using the shared communication parameter to establish a data link with the other communication apparatus;
• and
• in a second period including a period different to the first period, executing the predetermined service by a data link established by the data link control unit.
