Abstract

The present invention provides a communication system which includes a mobile communication apparatus, a modem, a gateway server, and a program processing apparatus. In addition, the communication system according to the present invention integrates mobile communication and instant messaging. More particularly, the communication system of the present invention is capable of providing an instant messaging user and a mobile communication user to perform instant video communication.

Claims

1. A communication system, for providing a first user to perform instant video communication with a second user, the communication system comprising:

a mobile communication apparatus, for generating a first video data stream related to the first user by operation of the first user, and transmitting the first video data stream to a modem via a mobile communication network, and the mobile communication apparatus receiving a second video data stream related to the second user via the mobile communication network from the modem, wherein the first video data stream has a first communication protocol, and the second video data stream has the first communication protocol;

the modem, for receiving the first video data stream via the mobile communication network, and transmitting the first video data stream to a gateway server, and receiving the second video data stream from the gateway server and transmitting the second video data stream to the mobile communication apparatus via the mobile communication network;

the gateway server, for receiving the first video data stream from the modem, and converting the first video data stream to a third video data stream related to the first user, and transmitting the third video data stream to a program processing apparatus via an internet, and the gateway server receiving a fourth video data stream from the program processing apparatus, and converting the fourth video data stream to the second video data stream, and transmitting the second video data stream to the modem, wherein the third video data stream has a second communication protocol, and the fourth video data stream has the second communication protocol; and

the program processing apparatus, for performing an instant messaging program, and generating the fourth video data stream related to the second user by operation of the second user, and transmitting the fourth video data stream to the gateway server via the internet, and receiving the third video data stream related to the first user from the gateway server.

2. The communication system of claim 1, wherein the mobile communication apparatus further comprises:

a first photographic device, for capturing a first image related to the first user; and

a first processing device, for converting the first image to the first video data stream.

3. The communication system of claim 2, wherein the mobile communication apparatus is a mobile phone or a personal digital assistant (PDA).

4. The communication system of claim 2, wherein the mobile communication apparatus is capable of supporting the third generation mobile communication.

5. The communication system of claim 2, wherein the mobile communication apparatus is capable of supporting the global system for mobile communication (GSM).

6. The communication system of claim 3, wherein the mobile communication apparatus is capable of supporting the general packet radio service (GPRS).

7. The communication system of claim 1, wherein the program processing apparatus further comprises:

a second photographic device, for capturing a second image related to the second user; and

a second processing device, for converting the second image to the fourth video data stream.

8. The communication system of claim 7, wherein the program processing apparatus is a computer or a personal digital assistant.

9. The communication system of claim 1, wherein the first communication protocol is a H.323 communication protocol or a WCDMA communication protocol.

10. The communication system of claim 1, wherein the second communication protocol is a session initiation protocol (SIP).

11. The communication system of claim 1, wherein the mobile communication apparatus is capable of providing the first user to dialing a represent number, and when the first user dials the represent number, the mobile communication apparatus is capable of displaying a list with a plurality of contact persons and brevity codes, wherein each of the brevity codes corresponds to one of the contact persons.
