BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. FIG. 1 is a schematic structural diagram of a video conference system according to an embodiment of the present invention. As shown in FIG. 1 , a video conference system according to an embodiment of the present invention includes: a host mobile terminal 12 for establishing a video call connection with one or more other host mobile terminals, and one or more connections with the access host mobile terminal. The mobile terminal is engaged in audio and/or video data interaction and forwards audio and/or video data from the access mobile terminal to one or more of the other host mobile terminals. One or more access mobile terminals 14 are used to access the host mobile terminal 12 and perform audio and/or video data interaction with the host mobile terminal 12. In the above video conference system, the use of the mobile terminal device to establish a video conference breaks the limitation of the traditional video conference hardware to the video conference itself, breaks through the regional limitation of the video conference, and greatly improves the portability and the freedom of conference establishment. Preferably, the mobile terminal 12 is further configured to send an operation instruction to the one or more access mobile terminals 14, wherein the operation instruction comprises: inviting to join the conference, allowing the speaking application, or the command to exit the conference. Preferably, the one or more access mobile terminals 14 may further send a request instruction to the host mobile terminal, where the request instruction includes: requesting to join the conference, requesting to speak, or applying to withdraw from the conference. After the video conference is established, the video conference system may further manage and adjust the video conference itself, and host the mobile terminal 12 to invite an access mobile terminal to join the conference, or allow a certain mobile terminal to apply for a speech. Let it speak at the conference, or order an access mobile terminal to leave the conference. Similarly, the accessing mobile terminal may send an application to the host mobile terminal to request to join the conference, or submit a request for speaking to the host mobile terminal, or voluntarily withdraw from the video conference. Preferably, the host mobile terminal can establish a video call connection with other host mobile terminals through the 3G mobile network. Preferably, the access mobile terminal can access the mobile terminal through a wireless local area network (Wireless LAN, WLAN for short). The videophone service is a multimedia communication service integrating image and voice, and is an iconic service of 3G mobile communication. It can realize face-to-face real-time communication, that is, both parties can see each other's scene during the call. At present, mobile operators all over the world have turned to the third generation mobile communication network, and video telephony is becoming a key part of the 3G service and its characteristic business. The WLAN is a LAN that uses a wireless connection. It uses radio waves as a medium for data transmission. The transmission distance is generally several tens of meters. The primary network of the wireless local area network usually uses a cable (CABLE), and the wireless office i or the network user accesses the wireless office i or the network through one or more wireless access points (WAP). Wireless Office i or Network is now widely used in business districts, universities, airports, and other public areas. The most common standard for wireless local area networks is the IEEE defined 802.11 family of standards. 802.1 lb defines a physical layer with a data transmission rate of up to l lMbit/s on the 2.4 GHz ISM band, and the 2.4 GHz ISM band is the vast majority of the world. Nationally versatile, so 802.11b is the most widely used. With such a high transmission rate, each access device in the same WLAN can not only perform simple data communication but also share video information. Moreover, with the spread of 3G networks and the popularity of WIFI networks, mobile phones with these two functions are becoming more and more popular, creating a good environment for the realization of the invention. Therefore, the two methods are used as a way to establish a video call connection and access the mobile terminal to access the mobile terminal, and all of the wireless connections can be implemented, which is the most convenient. Preferably, the host mobile terminal can also periodically broadcast the conference invitation information in the wireless office i or the network. After the video conference is built, there may be situations where you need to join a new conference member. In the case that the access mobile terminal accesses the mobile terminal through the wireless local area network access, if the member who newly joins the WLAN network cannot obtain the host IP, the new member cannot join the video conference, and the host mobile terminal periodically broadcasts the conference invitation in the wireless local area network. Information is to prevent this from happening. A preferred embodiment of the above video conferencing system is described below in conjunction with FIG. 2 is a block diagram showing the structure of a video conference system in accordance with a preferred embodiment of the present invention. As shown in FIG. 2, the system includes two host mobile terminals, namely, a host mobile terminal 222 and a host mobile terminal 224, which establish a videophone connection through a 3G network. After the videophone is established, the mobile terminals at both ends are hosted. 222 and 224 will enable the WLAN access function, increase the mobile terminal of the video conference by listening to the access request used in the local area network, pre-host the mobile terminal to set the password for joining the conference, and only use the access mobile that can correctly input the password. The terminal can join the video conference. The WLAN network also does not need to access the Internet, as long as the basic communication function of the local area network can be realized. Accessing mobile terminals such as 240 to 242 (only three access mobile terminals are shown in the figure, which may actually be one or more) may be connected to the mobile terminal 222 via the WLAN network, and the access mobile terminals 243 to 245 may also be connected. Such a video conferencing system is established through a 3G network and a WLAN network by connecting to the mobile terminal 224 via a WLAN network. When the mobile terminal specified by the conference is added to the video conference system, the conference can be officially started. The role of hosting a mobile terminal is not only to complete the establishment of a videophone channel, but also to be responsible for the activities of each mobile terminal in its own area, such as joining a conference, applying for a speech, withdrawing from a conference, and so on. If the access mobile terminal at one end wants to speak, he can make a request to the mobile terminal that hosts the mobile terminal. After the mobile terminal agrees, the mobile terminal will give the floor to the access mobile terminal, and then he can speak. At the other end of the conference system, all mobile terminals can hear his voice. If the access mobile terminal has a 4 head, the host mobile terminal can also transmit the video of the access mobile terminal to the other end. After the conference ends, the access mobile terminal can disconnect itself, and the host mobile terminal can also actively disconnect, so that the video conference system is completely completed. Using the above-mentioned video conferencing system architecture, it solves the problem between 3G mobile phones of different operators.

The 3G mode is not compatible and cannot be used for video calls. It is only necessary to host the same mode between the mobile terminals, and a video call connection can be established. There is no specific restriction on accessing the mobile terminal, and the mobile terminal is connected to establish a mobile terminal by using various methods such as WLAN in the prior art. The data is interactively connected. After the connection is established, the mobile terminal can be indirectly joined to the conference, which greatly improves the convenience of video conference formation. FIG. 3 is a flowchart of a method for implementing a video conference system according to an embodiment of the present invention. As shown in FIG. 3, the video conference system implementation method according to the embodiment of the present invention may include the following processing: Step S302, the host mobile terminal establishes a video call connection with one or more other host mobile terminals. Step 4: S304: After the mobile terminal establishes a connection with one or more access mobile terminals, perform audio and/or video data interaction with the one or more access mobile terminals. Step S306, the host mobile terminal forwards audio and/or video data between the one or more access mobile terminals and the one or more other host mobile terminals. Through the above method, that is, the use of the mobile terminal device to establish a video conference, the portability and the freedom of conference establishment are greatly improved. At the same time, using this specific architecture, the 3G mode between different operators' 3G mobile phones is not compatible, which makes it impossible to make video calls, which greatly improves the convenience of video conferencing. Preferably, after the video conference is established, one of the following processes may also be included: The host mobile terminal may perform an operation on the access mobile terminal, including but not limited to: inviting to join the conference, allowing the speaker to apply, and the command to exit the conference. The accessing mobile terminal may also send a request to the host mobile terminal, including but not limited to: requesting to join the conference, requesting to speak, or applying to withdraw from the conference. Through these processes, video conferences can be managed and adjusted to suit different situations. Preferably, the host mobile terminal establishes a video call connection with other host mobile terminals through the following network: a 3G mobile network. Preferably, the host mobile terminal establishes a connection by accessing the mobile terminal through the following network: a wireless office i or a network. In the preferred implementation process, the 3G mobile network and the wireless local area network are the most convenient and convenient way to establish a video call connection and access the mobile terminal to access the mobile terminal. The reason is described in detail in the system embodiment, and details are not described herein. . Preferably, after the video conference is established, the host mobile terminal can also periodically broadcast the conference invitation information in the wireless local area network. The host mobile terminal broadcasts the invitation information to the WLAN at intervals, which prevents the access mobile terminal that joins the WLAN network from obtaining the host IP. The above preferred embodiment will be described below in conjunction with FIG. 4 is a flow chart of a method of implementing a video conferencing system in accordance with a preferred embodiment of the present invention. As shown in FIG. 4, the implementation method of the video conference system mainly includes the following processing: Step S402: The hardware environment is ready for work. There are three conditions that must be met here:

(1) Mobile terminals that require participation in the video conference support WLAN functions;

(2) Two mobile terminals in the two places need to establish a mobile phone for videophone. The two mobile terminals will serve as the host mobile terminal. The role of the mobile terminal is not only to complete the establishment of the videophone channel, but also Responsible for the activities of each mobile terminal in your area, such as joining a meeting, applying for a speech, withdrawing from a meeting, etc.;

(3) The mobile terminals that need the two places are each located in two WLAN networks. If there is no WLAN network, the computer and the wireless router can be used to set up themselves, and the network does not need to be connected to the Internet, and only the communication function of the local area network can be realized. After the WLAN network is established, all mobile terminals in the two places need to connect to their respective WLAN networks. After obtaining the IP address, the video conference system can be established. Step 4: S404: The two mobile terminals selected as the host mobile terminal perform a videophone connection. The basic function of video conferencing is video transmission. The mobile terminals in the two places use 3G mobile network to realize audio and video communication. Step S406: After hosting the mobile terminal to establish a videophone, the mobile terminal is invited to join the video. meeting. The specific implementation method is as follows: (1) Hosting the mobile terminal to start to broadcast the invitation information of the video conference in the respective WLAN network, so that all the mobile terminals under the WLAN receive the invitation message;

(2) After each mobile terminal obtains the invitation information, it can know the IP address of the mobile terminal, and then the mobile terminal that wants to join the video conference sends the application information of the video conference to the IP address; (3) Hosting the mobile terminal After searching for the application information of other mobile terminals, the password-school insurance information is sent to the mobile terminal;

(4) After obtaining the verification information, the mobile terminal that wants to access will send the pre-defined password information to the host mobile terminal;

(5) After the mobile terminal-risk certificate is correct, the data channel is established with the mobile terminal that wants to access, so that the mobile terminal can share audio and video information with the host. The use of password verification can prevent any mobile terminal in the WLAN from joining the video conference, which enhances the confidentiality of the video conference;

(6) Hosting the mobile terminal will broadcast the invitation information in the WLAN at intervals, which can prevent the mobile terminal that joins the WLAN network from obtaining the host IP. Step 4: S408: At all mobile terminals; *卩 After joining the video conference, host the mobile terminal to organize the conference to begin. In the initial stage, the access mobile terminals in both places can only obtain the audio and video information of the mobile terminal, and the access mobile terminal connected to the video cannot speak casually, which is also determined by the characteristics of the videophone. If the access mobile terminal wants to speak, the following steps are required:

(1) The access mobile terminal needs to send a request for the floor to the mobile terminal hosting the network; (2) after the mobile terminal agrees, the local party's floor is handed over to the access mobile terminal, that is, the audio information is connected. Into the videophone, if the access mobile terminal has a camera, the host mobile terminal also accesses his video information to the videophone, so that all the mobile terminals at the other end can not only hear the speaker's voice, but also can see His appearance; (3) When his speech is over, he can voluntarily give up the right to speak, so that the mobile terminal can transfer the floor to the next access mobile terminal;

(4) All the mobile terminals in the two places can hear the voice of the two calls, and the video information can be obtained by self-selection. The choice is to receive the video of the other end speaker or the video of the local speaker. This fully realizes the function of a video conference. Step S410: After the conference ends, each mobile terminal may disconnect the host mobile terminal by itself, and the host mobile terminal may also actively shut down the system and disconnect the access mobile terminal. The host mobile terminal at the last two ends disconnects the videophone, and the entire video conference ends. In summary, with the above embodiments provided by the present invention, a convenient and fast video conference system is established by combining the 3G network and the WLAN, and the video conference system can be realized in an extremely convenient manner. At present, mobile phones with WLAN function are very popular, and the videophone function is quite mature. If the WLAN network cannot find a suitable one, it can be easily built by using a portable computer and a wireless router. This method of implementing a video conference is not only inexpensive, but also requires the payment of the videophone charges of the two hosts, and is not limited by hardware conditions, and the video conferencing system can be established by using simple devices and mobile phones even outdoors.
