Document Type and Number:
WIPO Patent Application WO/2016/051724
Kind Code:

Abstract:
A communication apparatus has a first communication function and a second communication function that has lower power consumption than the first communication function, and keeps information for communication based on the first communication function stored, even after the communication based on the first communication function with a partner apparatus is stopped. The communication apparatus determines whether the stored information is valid through communication based on the second communication function with the partner apparatus, and resumes the communication based on the first communication function with the partner apparatus upon re-obtaining the information for the communication based on the first communication function from the partner apparatus when at least a part of the stored information is not valid, and without re-obtaining the information for the communication based on the first communication function from the partner apparatus when the stored information is valid.
