Problems solved by technology
[0006] However, when the real-time media stream data transmission is realized through the protocol conversion gateway, the capability requirements of the video terminal are very high; for example, the above-mentioned traditional video service system requires that the H. Codec function, which will inevitably increase the production cost of the new terminal, but adopting this solution requires such a high-cost terminal, which increases the construction cost of the entire system; at the same time, when the transmission of mobile real-time media streams is realized based on the fixed-line network, Data is mainly transmitted through the circuit domain (CS domain), and the carrying capacity of the CS domain is very limited, only 64kbps, but this transmission rate cannot provide smooth video effects

The invention relates to a method, device and video conference system for transmitting real-time media stream data. The method comprises the following steps: receiving a transmission request of real-time media stream data from a terminal; encapsulating various protocol data contained in the request to obtain packet switch data packet which is loaded by mobile network; and using mobile network to transmit the switch data packet to a core network device so that the core network device transmits the decapsulated real-time media stream data to a target side terminal through IP network. Therefore, the method, device and system of the invention can be used to realize the effective transmission of mobile real-time media stream data; and the mobile network is adopted for transmission so as to ensure the broad bandwidth demand on the transmission of mobile real-time media stream data, and the existing terminal is not needed to modify and update, thus effectively controlling the cost.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for transmitting real-time media stream data and a video conferencing system. Background technique [0002] With the development of communication technology, people have higher and higher requirements for the transmission of various data services, especially the transmission of real-time media streaming data, such as video conferencing, teleconferencing, etc.; however, the existing real-time media streaming data Transmission is mainly realized through GSTN (General Switched Telephone Network, public switched telephone network), and with the increasing demand for real-time media stream data transmission, the demand for real-time media stream transmission anytime and anywhere while moving is also increasing. The more intense; and a possible solution to the mobile real-time media stream data transmission is to connect the mobile communication network system to the fi...
