Abstract

A communication system and method for dispatch service is suitable for RF communication system of a group, wherein the mobile device receives dispatch services of paging message on the first channel, then executes quick reply function via 2-Way Radio or GSM network, so as to transmit text or voice message to the dispatch center; the mobile device also comprises a channel scanning function and a double frequency scanning function, of which the channel scanning function is used to monitor and select a second channel and write into the device, and then the double frequency scanning function is executed to transmit message on the second channel

Claims

1. A communication method for dispatch service, with the communication procedures described below:

provide a RF mobile device at least with quick reply function, double frequency scanning function and channel scanning function, set it on the first channel to receive dispatch information sent from the dispatch center;

execute the quick reply function to send back a reply message to the dispatch center, confirming that the dispatch information is received;

execute the channel scanning function to capture an efficient channel related to the place of event;

make sure to define the channel captured as the second channel and write into the mobile device;

execute the double frequency scanning function for switching to the second channel to receive the message of current event.

2. The method defined in claim 1, wherein the quick reply function enables the reply message to be sent to the dispatch center through 2-Way Radio or GSM network.

3. The method defined in claim 1, wherein the reply message refers to message sent from the dispatch center or pre-stored in the mobile device;

the reply message is a text or voice message, comprising at least the name of the member or personal ID code.

4. The method defined in claim 3, wherein the reply message also comprises the position data of the mobile device.

5. The method defined in claim 1, wherein capturing a channel related to the place of event means that users may use a channel indicated in the dispatch information;

or execute the channel scanning function to scan and capture a channel from a plurality of channels in the air or pre-stored in the mobile device.

6. A communication system for dispatch service, which comprises at least a dispatch center and a plurality of mobile devices;

of which;

the dispatch center is equipped with at least a terminal, which is linked to a transmitter and a receiver via the host computer, and used to send message to the mobile devices of all members, or receive message from any mobile device, such that the dispatch center can communicated with the members with the mobile devices, monitor and manage the dispatching jobs;

the mobile device is selected from either the text/voice pager or two-way radio and carried separately by a member;

it at least comprises a processing control module, a RF receiving module, a display unit, an input module and a network communication module;

a) processing control module, connected to control various components;

it at least comprises quick reply function, double frequency scanning function and channel scanning function;

b) RF receiving module, in a normal open state;

it is firstly set on the first channel to receive the calling signals from the dispatch center, and select a second channel to receive the calling signals from the place of event, then input into the processing control module for interpretation;

c) display unit, used to display the audible or visible message interpreted by the processing control module on the mobile device;

d) input module, comprising at least the defined reset key, operating key and scanning key, which are separately used to execute quick reply function or double frequency scanning function, channel scanning function;

e) network communication module, selected at least from either 2-Way Radio or GSM network in a normal close state;

activated by the signals executing quick reply function or double frequency scanning function, used to send out the message from the processing control module.

7. The system defined in claim 6, wherein the processing control module is also connected with a conversation key and a microphone, of which the conversation key is used for executing push-to-talk functions;

and the microphone is used to receive the voice of the member, which is converted into paging signal by the processing control module, and then sent out by the communication module.

8. The system defined in claim 6, wherein the network communication module can be activated by the remote-controlled dispatch center when it is a GSM network.

9. The system defined in claim 8, wherein the mobile device can be provided with a GPS positioning module, which is activated by the quick reply function or the command of the dispatch center, so as to receive GPS data of the mobile device from the GPS system.

10. The system defined in claim 6, wherein the mobile device can be provided with a Bluetooth communication module, so as to transmit and receive voice signals for communication with a Bluetooth earphone.

11. The system defined in claim 6, wherein if the network communication module is selected from 2-Way Radio network, the RF communication module is a receiving circuit of the network communication module of 2-Way Radio network.
