    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.

    Abstract: Disclosed in embodiments of the present application are a resource allocation method, a device, and a medium. The method comprises: a terminal device determines N NPRACH transmission resources corresponding to a sending period of an ephemeris-bearing SIB bearing according to said sending period as well as configuration information for an NPRACH transmission resource indicated in an SIB2, where N is a natural number greater than zero; the terminal device randomly selects one NPRACH transmission resource from among the N NPRACH transmission resources; and the terminal device performs random access on a network device by means of the selected NPRACH transmission resource. By means of the present method, a terminal can randomly select one transmission resource to perform random access from among a plurality of available transmission resources, causing randomly delayed sending when the terminal performs random access, allowing for dispersion among different transmission resources, the probability of a collision is lowered, and the problem of random access failure caused by a transmission resource sending collision due to terminals initiating random access on a same transmission resource is effectively prevented.

    Abstract: Embodiments of the present application relates to a method and device for random access, for use in resolving the problem that no current random access process can satisfy requirements of a satellite communication system. The method of the embodiments of the present application comprises: receiving and obtaining a related parameter in a configuration message, the related parameter comprising common cell delay information; generating a physical random access channel random access preamble (PRACH Preamble) sequence, and determining an uplink sending timing location according to the common cell delay information; and sending the PRACH Preamble sequence on a time-frequency resource corresponding to the uplink sending timing location. A relative transmission delay and a multi-path channel delay from a terminal, to a satellite, and to a base station are compensated according to the determined uplink sending timing location, thereby reducing overheads of a PRACH channel.
