A communication apparatus determines whether to delete a packet yet to be transmitted that is stored in a transmission queue from the transmission queue when new data to be transmitted to another communication apparatus is generated. In a case where the packet yet to be transmitted is determined to be deleted, the communication apparatus deletes the packet yet to be transmitted that is stored in the transmission queue while maintaining the communication connection with the another communication apparatus, and transmits a packet to be transmitted corresponding to the new data to the another apparatus.
