Processed in specific BS270 to link signal.The data of acquisition are forwarded to the BSC275 of correlation.BSC provides call
Resource allocation and the mobile management function of the coordination including the soft switching process between BS270.BSC275 is also by the number for receiving
According to MSC280 is routed to, which is provided for the extra route service with PSTN290 formation interfaces.Similarly, PSTN290 with
MSC280 forms interface, and MSC and BSC275 form interface, and BSC275 correspondingly controls BS270 with by forward link signals
It is sent to mobile terminal 1 00.
Based on above-mentioned mobile terminal hardware configuration and communication system, the inventive method each embodiment is proposed.
The present invention is the screen prjection interaction solutions based on record screen function.With ARIXTRA in this specific embodiment
Illustrate based on (Android4.4 and above version) system, wherein：
Virtualdisplay：Virtual screen shows；
RTSP Server：RTSP streaming media servers；
Soft-AP：Hot spot networks；
WLAN Direct：WiFi is direct-connected.
Refer to Fig. 3, screen prjection method first embodiment of the present invention, for supporting the mobile terminal of record screen, the screen
Curtain projecting method comprises the steps：
Step S100, receives screen prjection instruction.
Step S200, by the display information for recording screen gain-of-function screen, that is, gathers the mobile terminal current screen
Display information.
Step S300, the display information is sent to streaming media server RTSP Server.Wherein, media server
RTSP Server start, or start when display information is obtained when can instruct the screen prjection is connected to.
Step S400, is sent the display information to network by the streaming media server RTSP Server, to
The screen that the mobile terminal is obtained by streaming media server RTSP Server described in network link access for receiving terminal is drawn
Face.
The present embodiment, by the display information for recording screen gain-of-function screen, then passes through streaming media server RTSP again
Server is distributed to network；Obtain by then receiving terminal is only needed by streaming media server RTSP Server described in network access
Display information, then can be played out by the built-in video player of receiving terminal, so as to realize the projecting function of screen-picture.
Relative to the Screen sharing scheme that must have screen prjection function realize, the receiving terminal of the present embodiment is realizing screen altogether
The technical requirements enjoyed are low, it is only necessary to access webpage, and there is video player to be capable of achieving Screen sharing, so as to have compatibility
Strong effect.Also, the present embodiment can access streaming media server RTSP Server for multiple receiving terminals, so as to realize screen
Curtain picture is shared to the effect of multiple equipment.
Refer to Fig. 4, screen prjection method second embodiment of the present invention, the present embodiment based on first embodiment, newly
