METHOD AND APPARATUS FOR ADAPTIVELY PROCESSING CONCURRENT SESSION IN IMS NETWORK

The present invention relates to the technical field of communications, and provides a method and an apparatus for adaptively processing a concurrent session in an IMS network. The method comprises the following steps: the IMS network receiving and storing parameters of a terminal maximum concurrent session quantity sent by a user terminal in a registration process; the IMS network determining a judging criterion value of the terminal maximum concurrent session quantity by using the parameters of the terminal maximum concurrent session quantity; the IMS network collecting statistics of a current concurrent session quantity of the terminal in real time, comparing the current concurrent session quantity of the terminal with the judging criterion value when a session about the user terminal is received, and then determining whether the user terminal is at a busy state, wherein the IMS refers to an IP multimedia sub-system. In the present invention, it is adaptively determined whether a user terminal is at a busy
