Abstract

A master-slave Bluetooth mobile communication system includes a host device and an extension device. The host device includes a call module, a first Bluetooth module and a first communication module. The extension device includes a second Bluetooth module and a second communication module. The first and second communication modules log in to a first and a second network domain respectively. The first and second Bluetooth modules provide an information channel between the host device and the extension device to transmit a data. The extension device informs the host device a login data of the second network domain. The host device communicates with a remote device through the first network domain or the information channel and the second network domain that the extension device logs into. Therefore, in a specific range, the host device uses functions of the extension device and a Bluetooth technology to log in to two network domains.

Claims

1. A master-slave Bluetooth mobile communication system, comprising:

a host device including a call module, a first Bluetooth module and a first communication module, the call module for receiving or transmitting at least one signal, the first communication module for logging in to a first network domain, and for enabling a primary telecommunication channel to be set up between the first communication module and a remote device through the first network domain, and the primary telecommunication channel for transmitting the signal between the host device and the remote device; and

an extension device including a second Bluetooth module and a second communication module, the second communication module for logging in to a second network domain, and the first Bluetooth module for detecting and connecting to the second Bluetooth module to form an information channel, wherein

the host device directs the extension device to enable, through the second communication module and the second network domain, a secondary telecommunication channel to be set up for connecting to the remote device, and the secondary telecommunication channel and the information channel are for transmitting the signal between the host device and the remote device.

2. The master-slave Bluetooth mobile communication system according to claim 1, wherein the first network domain is a GSM network domain, a CDMA network domain, a PHS network domain, a WCDMA network domain or a TD-SCDMA network domain.

3. The master-slave Bluetooth mobile communication system according to claim 1, wherein the second network domain is a GSM network domain, a CDMA network domain, a PHS network domain, a WCDMA network domain or a TD-SCDMA network domain.

4. The master-slave Bluetooth mobile communication system according to claim 1, wherein the call module includes a microphone, a speaker, a keyboard or a screen.

5. The master-slave Bluetooth mobile communication system according to claim 4, wherein the call module further includes a camera.

6. The master-slave Bluetooth mobile communication system according to claim 1, wherein the signal represents something selected from a group consisting of texts, voices and images.

7. The master-slave Bluetooth mobile communication system according to claim 1, wherein after the information channel is set up, the extension device transmits periodically configuration data of the second communication module through the information channel to the host device.

8. The master-slave Bluetooth mobile communication system according to claim 7, wherein a format of the configuration data corresponds with a profile defined according to Logical Link Control and Adaption Protocol.

9. The master-slave Bluetooth mobile communication system according to claim 7, wherein the second communication module is configured with an identification module for allowing the second communication module to log in to the second network domain, and the configuration data record a type of the identification module and a login state of the second communication module.

10. A network domain login method applied to a host device capable of communicating with an extension device by a Bluetooth standard, wherein the host device includes a first Bluetooth module and a first communication module which is used for logging in to a first network domain, the extension device includes a second Bluetooth module and a second communication module, and the network domain login method comprises:

detecting the second Bluetooth module of the extension device by the first Bluetooth module of the host device;

when the second Bluetooth module is detected, setting up an information channel between the first Bluetooth module and the second Bluetooth module;

accessing configuration data of the second communication module of the extension device through the information channel; and

the host device directing, according to the configuration data, the second communication module to log in to a second network domain and to access a packet from the second network domain.

11. The network domain login method according to claim 10, wherein a format of the configuration data corresponds with a profile defined according to Logical Link Control and Adaptation Protocol.

12. The network domain login method according to claim 11, wherein the second communication module is configured with an identification module for allowing the second communication module to log in to the second network domain, and the configuration data record a type of the identification module and a login state of the second communication module.

13. The network domain login method according to claim 10 further comprising:

determining whether the host device is to stand by under the first network domain and the second network domain simultaneously;

if it'"'"'s determined that the host device is not to stand by under the first network domain and the second network domain simultaneously, determining whether the host device is to stand by under the second network domain; and

if it'"'"'s determined that the host device is to stand by under the second network domain, analyzing a configuration state of the second communication module of the extension device based upon the configuration data, recording the configuration state in the host device, and the second communication module logging in to the second network domain.

14. The network domain login method according to claim 10 further comprising:

using the host device to output dial data and then transmitting the dial data to the extension device through the information channel;

using the second communication module to connect to a remote device, based upon the dial data, through the second network domain;

determining whether the connection to the remote device is successful; and

if it'"'"'s determined that the connection to the remote device is successful, setting up a telecommunication channel between the second communication module and the remote device, reporting back to the host device that the telecommunication channel is set up, and using the telecommunication channel and the information channel to transmit at least one signal between the host device and the remote device.

15. The network domain login method according to claim 14, further comprising reporting back to the host device, through the information channel, on connection failure, if it'"'"'s determined that the connection to the remote device is not successful.

16. The network domain login method according to claim 14, further comprising:

determining whether the host device receives a disconnection command;

if it'"'"'s determined that the disconnection command is received, requesting the extension device to disconnect a call; and

if it'"'"'s determined that the disconnection command is not received, determining whether a disconnection signal transmitted by the extension device is received.

17. The network domain login method according to claim 16, further comprising:

if it'"'"'s determined that the disconnection signal is received, outputting a message for disconnecting the call according to the disconnection signal; and

if it'"'"'s determined that the disconnection signal is not received, proceeding to the step of determining whether the host device receives the disconnection command.
