         [0129]    For the convenience of description, each part of the above apparatus is functionally divided into various modules or units to describe respectively. Of course, the function of each module or unit may be realized in the same or multiple software or hardware during the implementation of the disclosure. 
         [0130]    The disclosure will be illustrated below by means of an example. However, the following embodiments illustrated below are only used to illustrate and explain the disclosure, instead of constituting a limitation to the technical solution of the disclosure. 
         [0131]      FIG. 7  is a schematic flowchart of implementing remote video live broadcast based on streaming media. As shown in the figure, it may be included: 
         [0132]    Step  701 : a master mobile terminal (master streaming media client) initiates a voice call to a special service number; 
         [0133]    in specific implementation, the special service number is provided by an operator and configured to identify a service being operated by a user; when the mobile terminal calls the special service number, it means that the mobile terminal is intended to provide streaming media data; 
         [0134]    Step  702 : after receiving the voice call from the master mobile terminal, a network side device notifies a streaming media server; 
         [0135]    in specific implementation, the network side refers to an existing wireless communication network, including a wireless access network, a core network and the like; 
         [0136]    Step  703 : after receiving a notification, the streaming media server starts to establish a temporary access user packet and feeds back a message to the network side; at the same time, the streaming media server is in a state of waiting for the user to access; 
         [0137]    Step  704 : the network side device notifies, to the master mobile terminal, a message that the streaming media server is ready; 
         [0138]    in specific implementation, the notification message may include information of the temporary user packet of the streaming media server (the packet number being the number of the master mobile terminal) and the address and port information of the server, and the notification message may be transmitted by a wireless signalling procedure and be invisible to the user; 
         [0139]    Step  705 : after receiving the notification, the master mobile terminal initiates a connection with the streaming media server through a packet-switched domain according to the information in the message; 
         [0140]    in specific implementation, the connection simultaneously requests for accessing the temporary user packet provided by the streaming media server; 
         [0141]    Step  706 : after receiving a connection request sent by the master mobile terminal, the streaming media server establishes a connection with the master mobile terminal and notifies the network side device; 
         [0142]    Step  707 : the network side device issues a call success message and a connection establishment success message to the master mobile terminal; 
         [0143]    Step  708 : after receiving the call success message and the connection establishment success notification, the master mobile terminal displays a voice call completion interface which simultaneously displays an option of sending audio and video; and the user chooses to send audio and video, starts a local camera, starts to acquire audio and video data previewed by the camera, codes the audio and video data into streaming media data flows and sends the streaming media data flows to the streaming media server; 
         [0144]    in specific implementation, after receiving the connection establishment success notification, the master mobile terminal starts call transfer (all transfer) simultaneously and automatically, wherein the transfer number is the special service number; 
         [0145]    if the terminal is provided with a front camera and a back camera, the cameras may be switched during a video acquisition process; 
         [0146]    audio and video acquisition is the same as processing of a local camera module; however, since the audio and video acquired by the camera cannot be applied to streaming media playing directly, the acquired audio and video data needs to be coded in accordance with streaming media international standards; 
         [0147]    a Transmission Control Protocol/Internet Protocol (TCP/IP) is applied in the sending process of the data flows; 
         [0148]    Step  709 : after receiving the data flows sent by the master mobile terminal, the streaming media server distributes the data flows to all slave mobile terminals (slave streaming media clients) in the temporary user packet; 
         [0149]    the data flows are distributed by using a User Datagram Protocol (UDP), which can improve the utilization ratio of wireless bandwidths and the forwarding efficiency of the data flows. 
         [0150]    A processing flow of the master mobile terminal is described above, and processing of the slave mobile terminal will be described below. 
         [0151]    Step  710 : starting with Step  708 , the slave mobile terminal can initiate a call to the master mobile terminal at any time, and the call will be transferred to the special service number automatically according to the call transfer number; 
         [0152]    Step  711 : the network side notifies the number of the master mobile terminal and the number of the slave mobile terminal to the streaming media server; 
         [0153]    Step  712 : after receiving a notification, the streaming media server adds the number of the slave mobile terminal to the packet according to the packet number representative of the number of the master mobile terminal, and notifies the network side after adding the number of the slave mobile terminal to the packet successfully; 
         [0154]    Step  713 : the network side feeds a call success message back to the slave mobile terminal, and simultaneously notifies information of the streaming media server to the slave mobile terminal; 
         [0155]    in specific implementation, the information of the streaming media server includes information of the temporary user packet (the packet number being the number of the master mobile terminal) and the address and port information of the server, and the information of the streaming media server is transmitted by a wireless signaling procedure and is invisible to the user; 
         [0156]    Step  714 : after receiving the message notification, the slave mobile terminal displays a voice call completion interface which displays an option of receiving audio and video; the user chooses to receive audio and video, starts a local streaming media player, establishes a connection with the streaming media server through a packet-switched domain, starts to receive the streaming media data flows forwarded by the streaming media server, and decodes and plays the streaming media data flows locally; 
         [0157]    in specific implementation, the master mobile terminal and the slave mobile terminal may be exchanged, which means that any master mobile terminal may may serve as the slave mobile terminal while any slave mobile terminal may also serve as the master mobile terminal; 
         [0158]    the involved coding and decoding of the streaming media audio and video accord with standard requirements of the 3 rd  Generation Partnership Project (3GPP) and the Request for Comments (RFC) of the Internet Engineering Task Force (IETF); and 
         [0159]    the involved call signalling procedures accord with the standards of the 3GPP. 
         [0160]    The solution above may be implemented in any wireless terminal provided with a built-in camera, a streaming media module and protocols thereof. 
         [0161]    In specific implementation, the master mobile terminal may also serve as the mobile terminal which receives streaming media, while the slave mobile terminal may serve as the mobile terminal which provides the streaming media; the master mobile terminal refers to the terminal which provides streaming media data, while the slave mobile terminal refers to the mobile terminal which receives the streaming media data, that is, when a mobile terminal is providing streaming media data, the mobile terminal is the master mobile terminal, and when another mobile terminal is receiving the streaming media data, the another mobile terminal is the slave mobile terminal. 
         [0162]    It can be seen from the embodiments above that the technical solution provided by the embodiments of the disclosure solves the problem of the present unitary streaming media service and can be widely applied to mobile value-added fields including remote video teaching, training, conferences and the like. In addition, since mobile phone terminals are convenient to carry, the present solution can be used in any place with network coverage wherever and whenever in principle. The technical solution provided by the embodiments of the disclosure is an important expansion to streaming media service.
