In the present embodiment, suppose to set up Bluetooth personal local area network between the mobile phone of user A and the PC, and the mobile phone of user A has the function of embodiment three described PAN conventional equipments, the PC of user A supports the function of embodiment four described PAN central apparatus, after then the mobile phone of user A and PC set up Bluetooth personal local area network, the party A-subscriber opens video communication software such as QQ, MSN etc., user B also opens video communication software and connects by external network with user A on the PC of oneself at this moment, and user A just can directly use mobile phone to carry out multimedia messages (as video information or audio-frequency information) alternately by PC and user B like this.
Particularly, as user A by mobile phone cam capture video image and use the microphone speech of mobile phone, mobile phone sends to video image and sound on the video communication module of PC of user A through the Bluetooth personal local area network between mobile phone and PC, the PC of user A sends video image and the sound that the video communication module receives on the PC of external network user B to then; User B also can turn back to multimedia messages on the PC of user A simultaneously, then the PC of user A by and mobile phone between the Bluetooth personal local area network set up information that user B is returned be sent on the mobile phone of user A, like this user A directly use mobile phone just can realize by PC and user B between interaction of multimedia information.
If the corresponding a plurality of mobile phones of the PC of user A, these a plurality of mobile phones a plurality of users in corresponding external networks simultaneously then, the PC of user A can realize each mobile phone corresponding one by one with a plurality of users in the external network, and the interaction of multimedia information between a plurality of users in a plurality of mobile phones and the external network is provided.
In the present embodiment, set up Bluetooth personal local area network between PC by user A and at least one mobile phone, can realize the interaction of multimedia information between at least one mobile phone and the external network, thereby realized the practicality of mobile phone greatly, not only bring convenience efficiently and experience, can also save the expense that direct use mobile phone carries out interaction of multimedia information to the user.
At last, the all or part of step that realizes in the foregoing description method is understood in art technology those of ordinary skill field to be made and can instruct relevant hardware to finish by program, and described program can be stored in the computer read/write memory medium as ROM/RAM, magnetic disc, CD etc.
Certainly, the above is a preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
