Abstract

The invention discloses a communication system for assisting a user for retrieving geography-associated multimedia information, and the communication system comprises a data processing device and several mobile communication devices. The data processing device receives a first request information including a location term and a time term from a terminal device of the user, and broadcasting a second request information, based on the time term, to the mobile communication devices located within a region relative to the location term. The data processing device receives responding messages and captured audio and/or video data from the mobile communication devices accepting the second request information, and transmitting a location-related information to the terminal device based on the responding messages. The user transmits responding information responsive to the location-related information to the data processing device via the terminal device. The data processing device transmits the captured audio and/or video data (representative of the retrieved geography-associated multimedia information) relative to the responding information to the terminal device.

Claims

1. A communication system for assisting a user in retrieving geography-associated multimedia information, the user communicating with the communicating system via a terminal device, the communication system comprising:

a plurality of mobile communication devices; and

a data processing device, capable of communicating with the mobile communication devices, receiving a first request information including a location term and a time term from the terminal device, broadcasting a second request information, based on the time term, to the mobile communication devices located within a region relative to the location term, receiving a plurality of responding messages and captured audio and/or video data from the mobile communication devices accepting the second request information, and transmitting a location-related information to the terminal device based on the responding messages,

wherein the user transmits a responding information responsive to the location-related information to the data processing device via the terminal device, the data processing device transmits the captured audio and/or video data, relative to the responding information and representative of the retrieved geography-associated multimedia information for the user, to the terminal device.

2. The communication system of claim 1, wherein each mobile communication device comprises a positioning module for receiving a positioning signal and transforming the positioning signal into a positioning information, the mobile communication devices transmit the positioning information to the data processing device, the data processing device broadcasts the second request information to the mobile communication devices transmitting the positioning information relative to the location term.

3. The communication system of claim 2, wherein the positioning module is a wireless fidelity (Wi-Fi) positioning module, a global positioning system (GPS) module, an assisted global satellite positioning system (AGPS) module, or a Galileo satellite positioning module.

4. The communication system of claim 1, wherein the time term is a time interval, the terminal device generating a moving path information according to the time interval and the location-related information received in the time interval.

5. The communication system of claim 1, wherein the first request information further comprises an event term, the data processing device receiving a plurality of event information from the mobile communication devices and broadcasting the second request information to the mobile communication devices which transmit the event information relative to the event term and is located within the region relative to the location term.

6. The communication system of claim 1, wherein the data processing device communicates with mobile communication devices via a wireless communication network.

7. The communication system of claim 6, wherein the wireless communication network is a high speed packet access (HSPA) network, a wireless fidelity (Wi-Fi) positioning network, or a worldwide interoperability for microwave access (WiMAX) network.

8.
