A series of pure polyoxometalate salts, Kx[PMo12O40]3- (KxPMo, x=1,2,3, 4), have been successfully prepared used F127 as template by one pot hydrothermal method. This obtained KxPMo materials are with mesoporous,...

In view of IP multimedia subsystem (IMS) which is the focus of technical research in the field of communication, analyse the scheme of IMS network based on service provision and service triggering mechanism. According to the application triggering architecture, service triggering data and service triggering process, this paper carried out a detailed analysis, and set up IMS system basing on Linux operating system. Then take a test to the system function whose results show that the service scheme ensures the normal use of services provided by IMS service architecture when a user is performing IMS calling.
