(The circuit domain of the R4 core network includes MSCServer/VLR, MGW, SGW, and HLR equipment. The MSCServer first terminates the functions of call control, mobility management, authentication and encryption in the CS domain. The MGW terminates the bearer control and bearer transmission functions, and performs bearer resource management and bearer establishment and release according to the request of the MSCServer. The SGW is generally embedded in the MSCServer or the MGW network element, and firstly terminates the conversion of signaling.)
