step 3, selecting a virtual subnet; the virtual subnet selects by the terminal starting up, reading IMSI and VSNID from SIM card, the terminal executing virtual subnet selecting process in PLMN selecting process, the terminal only selecting access network corresponding to VSNID in SIM card, the access network selecting corresponding core network element according to VSNID, the access network broadcasting its own virtual subnet identification information list in system broadcast message, the terminal reading signed virtual subnet identification information from SIM card, the terminal comparing VSNID after receiving system broadcast message, the terminal only selecting access network having same virtual subnet identification as itself to execute subsequent process, the access network directly sending register request to core network of the virtual subnet.
9. The satellite ground access station system based on the dynamic resource pool virtualization technology as claimed in claim 1, wherein the ground access station constitutes hardware resources, the hardware resources adopt a centralized architecture, and the computing resources are subjected to centralized deployment, horizontal pooling and statistical multiplexing, and then a virtual resource pool is established on a unified infrastructure hardware facility by using the virtualization technology in the centralized architecture, so as to further support flexible scheduling of the ground access station resources, the centralized architecture logic function is separated from physical hardware, and the creation as required, dynamic deployment and resource allocation of the virtual ground access station are completed through a unified open software interface, and coordination and optimized intelligent control of various software and hardware resources are uniformly performed.
