Mainly contain dummy node, finite-state automata (Finite status Automation at satellite communication network network state acquisition methods commonly used at present, abbreviation FSA), snapshot series, dynamic virtual topology (Dynamic Virtual Topology, be called for short DVTR) etc., general all is to make up the corresponding static topology according to specific satellite network, and utilizes this static topology to detect the signal intelligence of particular satellite network.
Existing these satellite communication network network state acquisition methods generally all are simply the satellite network period T evenly to be divided into the individual state of N (N is the integer greater than zero), and suppose network topological novariable in time between per two states, in certain approximate extents, satellite communication network is equal to traditional communication network, thereby can utilize existing mature technology, obtain the network state of mobile satellite network communication system based on fixed topology.
But existing method is to the not check and analysis in depth of network state of mobile satellite communication network system, for example: do not consider the state when mobile-satellite switches, but it is summed up as the change in topology of next state, can accurately not obtain the network state of mobile satellite network, because the network state that obtains is accurate inadequately, caused the network service Effect on Performance, only be adapted to node and switch fewer satellite network (as some special individual layer satellite network); Simultaneously, these methods generally also are to provide by rule of thumb for choosing of status number N, do not have strict theoretical direction, and diverse ways all only at a certain class satellite network, has significant limitation.
