Abstract

A communication apparatus is disclosed which communicates with a second communication apparatus via a base station. The communication apparatus includes an incoming call notice receiving unit for receiving an incoming call notice including picture transmission information signaling that the second communication apparatus is planning to send a picture via the base station; a picture receiving unit for receiving the picture sent from the second communication apparatus; and a display unit for displaying the picture received by the picture receiving unit. The picture transmission information has identification information for identifying the type of the picture to be sent by the second communication apparatus, and the display unit displays the picture type along with the picture.

Claims

1. A communication apparatus for communicating with a second communication apparatus via a base station, said communication apparatus comprising:

an incoming call notice receiving unit which receives an incoming call notice including picture transmission information signaling that said second communication apparatus is planning to send a picture via said base station;

a picture receiving unit which receives said picture sent from said second communication apparatus; and

a display unit which displays said picture received by said picture receiving unit;

wherein said picture transmission information has identification information for identifying the type of said picture to be sent by said second communication apparatus; and

wherein said display unit displays the picture type along with said picture.

2. A communication apparatus according to claim 1, wherein said identification information identifies said picture as either a real-time picture or a stored picture.

3. A communication apparatus according to claim 1, further comprising a storage unit which stores telephone numbers of a plurality of communication apparatuses;

wherein, if the telephone number of said second communication apparatus is not stored in said storage unit, then said display unit gives a display requesting a decision whether or not to display said picture received by said picture receiving unit.

4. A communication apparatus according to claim 1, further comprising:

a reception determining unit which determines whether or not to receive said picture depending on said picture transmission information; and

a sending unit which, if said reception determining unit has determined not to receive said picture, then sends to said base station information signaling a refusal to receive said picture.

5. A communication apparatus for communicating with a second communication apparatus via a base station, said communication apparatus comprising:

a picture sending unit for sending a picture;

an outgoing call request sending unit for sending to said base station an outgoing call request including picture transmission information asking whether said picture sending unit may send said picture to said second communication apparatus; and

a control unit which, upon receipt of reception refusal information from said second communication apparatus signaling a refusal to receive said picture, causes said picture sending unit not to send said picture.

6. A communication apparatus according to claim 5, wherein, if said reception refusal information is not received before the receipt of a notice from said base station signaling establishment of a communication circuit with said second communication apparatus, then said control unit causes said picture sending unit to send said picture.

7. A communication apparatus according to claim 5, wherein, upon receipt of reception acceptance information signaling that said second communication apparatus is ready to receive said picture, said control unit causes said picture sending unit to send said picture.

8. A communication apparatus according to claim 5,

wherein said picture transmission information has identification information for identifying said picture as either a real-time picture or a stored picture.

9. A communication apparatus having a telephone capability, comprising:

an input unit for inputting a telephone number;

a determination unit for determining whether or not to send a picture to a destination corresponding to said telephone number input by said input unit; and

a sending unit which, if said determination unit has determined to send said picture, then sends to said destination said picture along with identification information for identifying the sent picture either as a real-time picture or a stored picture.

10. A communication system for allowing a first communication apparatus and a second communication apparatus to communicate with each other via a base station;

said communication system comprising;

(a) said first communication apparatus which comprises;

an outgoing call request sending means for sending to said base station an outgoing call request including picture transmission information signaling that said first communication apparatus is planning to send a picture to said second communication apparatus; and

a picture sending means for sending said picture; and

(b) said second communication apparatus which comprises;

an incoming call notice receiving means for receiving from said base station an incoming call notice including said picture transmission information signaling that said first communication apparatus is planning to send said picture;

a picture receiving means for receiving said picture sent from said first communication apparatus; and

a displaying means for displaying said picture received by said picture receiving means;

wherein said picture transmission information has identification information for identifying the type of said picture to be sent by said second communication apparatus; and

wherein said displaying means displays the picture type along with said picture.
