    Abstract: A control method and a control device in a heterogeneous three-dimensional hierarchical network, and a communication system are provided. The control method includes: obtaining a coverage mode of a terminal; when the coverage mode is single-layered sub-network coverage, setting a non-ground mobile communication sub-network or a ground mobile communication sub-network corresponding to the single-layered sub-network coverage to be in a standalone operating mode or an intra-layer carrier aggregation mode; and when the coverage mode is multi-layered sub-network coverage, setting the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, or the ground mobile communication sub-network and the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, to be in a cross-layer carrier aggregation mode. The ground mobile communication sub-network and the non-ground mobile communication sub-network use a same or unified radio access technology.

    Abstract: The present application provides a method and a device for determining sending parameters of a terminal. The method comprises: firstly determining a pre-estimated uplink signal-to-noise ratio of at least one reference position in a cell range corresponding to a satellite beam, determining, according to the pre-estimated uplink signal-to-noise ratio, an EIRP value corresponding to the preset uplink carrier bandwidth of the corresponding reference position, determining, according to the EIRP value corresponding to the preset uplink carrier bandwidth, a maximum rate supported by the preset uplink carrier bandwidth, determining, according to the maximum rate supported by the preset uplink carrier bandwidth, a maximum uplink rate supported by the terminal, and determining uplink sending parameters of the terminal according to an uplink rate which is inputted by the user, is not greater than the maximum uplink rate supported by the terminal and is to be supported by the terminal. The method can quickly and reasonably determine uplink sending parameters of a terminal, so that a control device in a satellite mobile communication system allocates a relevant resource to the terminal according to the obtained uplink sending parameters of the terminal, thereby guaranteeing reasonable use of system resources.
