Abstract
A communicating apparatus which stores communication obstacle information in the case where a communication obstacle occurs. The apparatus comprises a memory to store communication information and a managing unit to manage the information stored in the memory in accordance with information stored in a communication partner, wherein the managing unit processes the information stored in the memory in accordance with the recovery of the communication obstacle or the number of communication obstacles.
