A communication control terminal apparatus employs one CPU to control two or more communication procedures, without adversely affecting each other. The communication control terminal apparatus includes a storage unit for storing information by using predetermined codes, a codec unit for coding and decoding the information, and communication control units for transmitting the information. A communication code obtained by the codec unit through conversion is transmitted via the communication control units. An execution time for the codec unit is changed in accordance with types of the communication procedures performed by the communication control units.
