Communication apparatus, communication method, and storage medium

A communication apparatus comprising:

• a first connection unit configured to connect to a first access point;
• a first establishment unit configured to, to execute a service between the communication apparatus and another communication apparatus, share address information of the communication apparatus and the another communication apparatus, identification information of a service, and identification information of a session, and establish a session with the another communication apparatus via the first access point connected by the first connection unit;
• a detection unit configured to detect an occurrence of a condition for switching from a communication method using the first access point to a communication method for communicating directly with the another communication apparatus after establishing a session with the another communication apparatus via the first establishment unit;
• a storage unit configured to store the address information of the communication apparatus and the another communication apparatus, the identification information of the service, the identification information of the session, and status information of the session;
• a disconnection unit configured to disconnect from the first access point based on the detection by the detection unit;
• a second connection unit configured to connect with the another communication apparatus after the disconnection by the disconnection unit;
• and
• a second establishment unit configured to, to continue the service between the communication apparatus and the another communication apparatus, establish a session with the another communication apparatus connected by the second connection unit by using the address information of the communication apparatus and the another communication apparatus, the identification information of the service, the identification information of the session, and the status information of the session stored by the storage unit.
