## Background
FIELD OF THE INVENTION
The present invention relates to an instant message audio connection management system, and more particularly to an instant message audio connection management system for integrating plural instant message tools therewith and dynamically selecting an audio device. The present invention also relates to an instant message audio connection management method.
BACKGROUND OF THE INVENTION
With increasing development and cost-effectiveness of the network technology, instant message software now rapidly gaining in popularity. For example, the well-known instant message software such as MSN Messenger, Skype, Yahoo Messenger and the like becomes the popular instant message tool. Such instant message software usually has a voice chat function. For most users, many different instant message tools are used to execute the voice chat function.
Although many different instant message tools installed in a same computer system provide diversity of executing the voice chat function, there are still some drawbacks. For example, when a remote user sends a chat invitation to a local user, the local user should find out the corresponding instant message tool at first. When the local user is invited to chat, a chat window is displayed on the computer screen. Next, the chat window is used as the foreground window, and then the local user may trigger a confirmation key on the foreground window to have the instant message software execute the voice chat function. That is, the procedure of executing the voice chat function by a specified instant message tool is both complicated and time-consuming.
Moreover, before the voice chat function is executed, the audio device should have been previously defined, which is also troublesome. Typically, there are two approaches of switching the audio device. The first approach defines or switches the audio device via the operation system of the computer. After the audio device is defined or switched, the instant message tools should be rebooted. The second approach defines or switches the audio device via the functional option menu provided by the instant message tools. If a voice chat is proceeding, the procedure of switching the audio device is not permitted. In other words, the voice chat needs to be terminated in order to switch the audio device. Therefore, such an approach is very inconvenient.
As known, the commercial audio devices for voice chat include for example bluetooth earphones, USB phones and the like. Unlike the conventional mobile phone, the instant message tools fail to be directly used with the Bluetooth device to respond the chat invitation or have a chat. In other words, the bluetooth earphones can be used as the general audio devices. After the Bluetooth connection software is executed, the bluetooth earphone is communicated with the computer. Then, the bluetooth earphone is defined or switched as the audio device by the above-mentioned inconvenient approaches.
In views of the above-described disadvantages resulted from the prior art, the applicant keeps on carving unflaggingly to develop an instant message audio connection management system and method according to the present invention through wholehearted experience and research.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic functional block diagram illustrating an instant message audio connection management system according to a preferred embodiment of the present invention; and
FIG. 2 is a flowchart illustrating an instant message monitoring and controlling method of the present invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
An instant message audio connection management system according to a preferred embodiment of the present invention is illustrated with reference to the schematic functional block diagram of FIG. 1. The instant message audio connection management system 100 of FIG. 1 can be applied to a notebook computer and/or a personal digital assistant (PDA).
Several different instant message tools 112, 114 and 116 are integrated into this system, so that the local user can receive the chat invitation from the remote user employing one of these instant message tools. Moreover, the audio data can be rerouted between different audio devices. Even when the local user is having a chat, the audio device may be switched as required.
The instant message audio connection management system 100 of the present invention further refers to the use mode of the bluetooth earphone, so that the voice chat is accepted or terminated when the multifunction key thereof is activated. As a consequence, the instant message audio connection management system 100 of the present invention is convenient and user-friendly.
The instant message audio connection management system 100 of FIG. 1 includes an instant message monitoring and controlling module 110, a user operation interface 120 and a bluetooth module 130. By wired communication networks or wireless communication networks, the instant message monitoring and controlling module 110 is communicated with the instant message tools 112, 114 and 116 in order to monitor and control these instant message tools 112, 114 and 116. An example of the wired communication networks include but are not limited to world wide webs, wide area networks (WANs), local area networks (LANs) or various special lines. Exemplary wireless communication networks include mobile phone networks or wireless local area networks (WLANs). For example, the instant message tools 112, 114 and 116 are MSN Messenger, Yahoo Messenger and Skype, respectively. The instant message monitoring and controlling module 110 is responsible for detecting the packets transmitted by the instant message tools 112, 114 and 116, and discriminating whether someone invites to chat or whether either of the instant message tools 112, 114 and 116 is being used to have a chat with the system 100.
By the instant message monitoring and controlling module 110, the priority order of the instant message tools 112, 114 and 116 is determined. In an embodiment, according to the priority order setting, the instant message tool 112 (e.g. MSN Messenger) has a higher priority than the instant message tool 114 (e.g. Yahoo Messenger) and the instant message tool 114 has a higher priority than the instant message tool 116 (e.g. Skype). When the local user is invited to chat by several chat invitations at the same time, the instant message tool having a higher priority is selected to respond the invitation. For example, in a case that chat invitations are simultaneously received by the instant message tools 112 and 114, the connection management system will respond to the instant message tool 112 according to the priority order setting. Even when the local user is having a chat with the system 100 by the instant message tool 116, the chat will be interrupted and an audio connection between the instant message monitoring and controlling module 110 and another instant message tool having a higher priority (for example the instant message tool 112, e.g. MSN Messenger) will be established.
Via the user operation interface 120 of the system 100, the functions of a bluetooth device 132 and a non-bluetooth device 134 are defined. For example, the bluetooth device 132 is a bluetooth earphone to be defined as a first audio device or a preset audio device. The non-bluetooth device 134 is for example an external speaker and microphone to be defined as a second audio device or an external audio device.
In accordance with a feature of the present invention, the bluetooth module 130 will automatically search a paring code of the bluetooth device 132. Take a bluetooth earphone as the bluetooth device 132 for example. The instant message monitoring and controlling module 110 may actively locate the bluetooth earphone and try to communicate with the bluetooth earphone by searching the paring codes (e.g. 4444, 0000, 1234, etc.) of the general bluetooth earphone. If there is a successful paring, the connection between the instant message monitoring and controlling module 110 and the bluetooth device 132 is established. Under this circumstance, the local user may chat with the remote user by using one of the instant message tools 112, 114 and 116.
Moreover, the instructions issued from the bluetooth device 132 can be transmitted to the instant message monitoring and controlling module 110 through the bluetooth module 130, thereby controlling the audio communication operations of the instant message tools 112, 114 and 116. Examples of the audio communication operations include but are not limited to reception of audio chat invitations, call waiting of audio chats, ending chats, having video chats, and so on. For example, after the bluetooth module 130 successfully searches a pairing code and the connection between the instant message monitoring and controlling module 110 and the bluetooth device 132 is established, the bluetooth device 132 can receive the chat invitation sent from the instant message tool 112 when the multifunction key thereof is activated.
In some embodiments, the system 100 further includes a hot key module 140. By actuating the hot key module 140, an audio device is disabled but another audio device is enabled. For example, via the user operation interface 120, a hot key is defined to implement the functions originally triggered by several individual function keys. In an embodiment, a specified function key on the bluetooth device 132 is a hot key. When the hot key is pressed down, the built-in audio device (not shown) of the system 100 can be switched to the bluetooth device 132. It is noted that, however, those skilled in the art will readily observe that numerous modifications and alterations of the functions of the hot key module may be made while retaining the teachings of the invention. For example, by actuating the hot key module 140, the bluetooth device 132 is switched to the non-bluetooth device 134, or the built-in audio device (not shown) of the system 100 is switched to the non-bluetooth device 134, or the bluetooth device 132 is switched to another bluetooth device (not shown). Accordingly, the above disclosure should be limited only by the bounds of the following claims.
Moreover, the hot key module 140 is also used for controlling the audio communication operations of the instant message tools 112, 114 and 116. Likewise, via the user operation interface 120, a hot key of the hot key module 140 is defined to implement the functions originally triggered by several individual function keys.
In some embodiments, the system 100 further includes an audio screening module 150. For example, the audio screening module 150 is composed of an audio screening proxy (not shown) and an audio screening driver (not shown). When one of the instant message tools 112, 114 and 116 is executed to have a chat with the system 100, an audio device switching instruction may be issued to the system 100 by the user operation interface 120 and the hot key module 140. In response to the audio device switching instruction, the built-in audio device is switched to the external audio device such as the bluetooth device 132 or the non-bluetooth device 134. The specified information issued from the system 100 will be received by the audio screening proxy of the audio screening module 150 and then transmitted to the audio screening driver. Under this circumstance, the audio data will be rerouted from the built-in audio device to the selected audio device such as the bluetooth device 132 or the non-bluetooth device 134. The detailed description of the audio screening module 150 is disclosed in for example a co-pending Taiwanese Patent Application No. 094147667, entitled “Dynamic audio data rerouting system, structure and method”, which was filed by the same assignee of the present application on Dec. 30, 2005, and the contents of which are hereby incorporated by reference.
Hereinafter, an instant message monitoring and controlling method will be illustrated with reference to the flowchart of FIG. 2. This method is applied to the instant message monitoring and controlling system 100 as shown in FIG. 1. The system 100 of FIG. 1 includes an instant message monitoring and controlling module 110 for monitoring and controlling the instant message tools 112, 114 and 116; a user operation interface 120 for defining the selected audio device such as the bluetooth device 132 or the non-bluetooth device 134; a bluetooth module 130 for automatically searching the pairing codes required for connection with the bluetooth device 132; a hot key module 140 actuated to be switched to the desired audio device; and an audio screening module 150 for rerouting the audio data to the selected audio device such as the bluetooth device 132 or the non-bluetooth device 134.
First of all, the instant message monitoring and controlling module 110 monitors and controls the data of the instant message tools 112, 114 and 116 (Step 202). For example, the instant message monitoring and controlling module 110 is responsible for detecting the packets transmitted by the instant message tools 112, 114 and 116, and discriminating whether someone invites to chat or whether either of the instant message tools 112, 114 and 116 is being used to have a chat with the system 100.
If one of the instant message tools 112, 114 and 116 is invited to chat (Step 204), it is determined whether either of the instant message tools 112, 114 and 116 is being used to have a chat with the system 100 (Step 206). For example, if the instant message tool 114 is being used to have a chat with the system 100 and the instant message tool 112 is invited to chat, the instant message monitoring and controlling module 110 will determine the priority order of the instant message tools 112 and 114 (Step 208). If the instant message tool 112 has a higher priority than the instant message tool 114, the chat by the instant message tool 114 will be interrupted and an audio connection between the instant message monitoring and controlling module 110 and the instant message tools 112 will be established. Whereas, if the instant message tool 112 has a lower priority than the instant message tool 114, the chart invitation by the instant message tool 112 is ignored.
Whereas, if no other instant message tool is being used to have a chat with the system 100 (Step 206), the instant message monitoring and controlling module 110 will accept the chat invitation of the instant message tool 114 (Step 210). When the chat is proceeding, the built-in audio device can be switched to the bluetooth device 132 via the user operation interface 120 and/or the hot key module 140 (Step 212).
In a case that the selected audio device is the bluetooth device 132, the bluetooth module 130 will automatically search paring codes required for connection with the bluetooth device 132. For example, if the bluetooth earphone is defined as the bluetooth device 132 via the user operation interface 120, the instant message monitoring and controlling module 110 may actively locate the bluetooth earphone and try to communicate with the bluetooth earphone by searching the paring codes (e.g. 4444, 0000, 1234, etc.) of the general bluetooth earphone. If there is a successful paring, the connection between the instant message monitoring and controlling module 110 and the bluetooth device 132 is established. Under this circumstance, the local user may chat with the remote user by using one of the instant message tools 112, 114 and 116.
In response to the audio device switching instruction, the specified information issued from the system 100 will be received by the audio screening proxy of the audio screening module 150 and then transmitted to the audio screening driver. Under this circumstance, the audio data will be rerouted from the built-in audio device to the selected audio device such as the bluetooth device 132 or the non-bluetooth device 134 (Step 214).
Alternatively, the audio device switching instruction may be transmitted from the bluetooth device 132 to the system 100 through the bluetooth module 130, thereby controlling audio communication operations of the instant message tools 112, 114 and 116. Examples of the audio communication operations include but are not limited to reception of audio chat invitations, call waiting of audio chats, ending chats, having video chats, and so on. For example, after the bluetooth module 130 successfully searches a pairing code and the connection between the instant message monitoring and controlling module 110 and the bluetooth device 132 is established, the bluetooth device 132 can receive the chat invitation sent from the instant message tool 112 when the multifunction key thereof is activated.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
