1. A communication apparatus providing common data service, the apparatus comprising:
an input unit in which a user:
inputs, in a first recipient field provided at the apparatus, identification (ID) information on a plurality of communication apparatuses;inputs first data to generate common data that includes the first data, in a data field provided at the apparatus; andselects, in a second recipient field provided at the apparatus, ID information on a second communication apparatus, which first receives the common data, that includes the first data, from among the ID information on the plurality of apparatuses input into the first recipient field, wherein the second communication apparatus of the plurality of apparatuses is the only apparatus, among the plurality of apparatuses, which receives the common data and the ID information on the plurality of apparatuses from the communication apparatus; a display unit that displays a menu list having a general message menu and a common message, displays the first recipient field for inputting the ID information on the plurality of apparatuses in response to the common message menu being selected, and displays the data field for inputting the first data and the second recipient field for selecting the ID information on the second communication apparatus of the plurality of apparatuses among the ID information on the plurality of apparatuses; a transmission unit that transmits the common data, that includes the first data, and the ID information on the plurality of apparatuses to only the second communication apparatus of the plurality of apparatuses using the selected ID information on the second communication apparatus; a packet generating unit which generates the common data by adding the first data; and a reception unit that receives answer data from the second communication apparatus of the plurality of apparatuses, wherein the packet generating unit is further configured to add the answer data to the common data that includes the first data, wherein the input unit is further configured to input, in the second recipient field displayed at the apparatus providing common data service, ID information on a third communication apparatus of the plurality of apparatuses that is permitted by the user to receive the common data that includes the first data and the answer data and to add the other data to the received common data, and wherein the transmitting unit is further configured to transmit the common data, that includes the first data and the answer data, and the ID information on the plurality of apparatuses to the other apparatus using the ID information on the third apparatus, and wherein the first data and the other data are data exchanged between wireless handheld devices through a short message service (SMS) or long message service (LMS) provided for the wireless handheld devices. |
