In a communication system arranged by a cordless handset, a base unit, and a charging base, the charging base is constructed by employing a cordless handset power supply unit for charging a secondary battery of the cordless handset; a portable terminal appliance power supply unit for charging the portable terminal appliance; and further, a data transmitting and receiving unit capable of transmitting and receiving data between the portable terminal appliance and the cordless handset data storage unit. With employment of this arrangement, the data transmitting and receiving unit of the charging base transmits and receives data between the portable terminal appliance and the cordless handset, and transfers a telephone number from the cordless handset to the portable terminal appliance, or from the portable terminal appliance to the cordless handset. This transferred telephone number can be utilized so as to make a telephone call. Also, data which is entered to the portable terminal appliance is transmitted via the charging base and the cordless handset to a base unit data storage unit, so that this data can be utilized by the base unit.
