Method, system, content server, GGSN, and SGSN for switching traffic during real time stream transmission

摘要

A method for switching traffic during real time stream transmission depends on a network side device to identify the start and end of the stream transmission, and to perform a switching between Best Effect traffic and the streaming traffic. The network side device can be a stream media content server, a Serving General Packet Radio Service (GPRS) Support Node (SGSN) or a Gateway General Packet Radio Service Supporting Node (GGSN) of a Core Network (CN). A system for switching traffic during a real time stream transmission, a content server for real time stream transmission, a GGSN for real time stream transmission, an SGSN for real time stream transmission are also disclosed.
