[0002] Communication satellites are typical bandwidth and power-constrained systems. Therefore, how to efficiently utilize the scarce communication resources of satellites while ensuring the quality of service for various services is the key to improving the usability of communication satellites. In broadband satellite systems, efficient reuse of resources in the time domain, frequency domain, and power domain is conducive to the transmission of higher-speed services, greatly improving the communication capacity of the system.

A satellite communication system resource allocation mode lightweight reconfigurable modeling system according to claim 5, characterized in that: The TDMA allocation method comprises the following steps: S71, according to the ID information of the applied transponder, combined with the bandwidth resource pool information sent by the ground station model and the resource application information sent by the terminal model, determine whether the remaining bandwidth resource pool under the applied transponder meets the bandwidth resources applied by the terminal, if yes, proceed to step S72; otherwise, proceed to step S73; S72, allocate bandwidth resources according to the priority and the order of arrival of the application, generate a carrier resource allocation result, and proceed to step S76; S73, according to the sequence of the allocated terminal ID set sent by the ground station model, compare the priorities of the terminals to which resources have been allocated and the terminals to which resources are to be allocated under the repeater; S74. If the priority of the terminal with allocated resources under the allocated carrier is higher than the priority of the terminal with resources to be allocated, compare the priority of the terminal with allocated resources under the next carrier; otherwise, record the low-priority terminal ID under the carrier and send it to the ground station model; S75, repeating steps S71-S74, if the bandwidth demand of the terminal to be allocated resources still cannot be met after releasing all bandwidth resources under the forwarder, it is determined that the resource allocation fails; S76, determining whether the remaining time slot resource pool under the allocated carrier meets the terminal application requirements; if so, generating a final resource allocation result; If not, a priority comparison is performed between the terminals to which resources have been allocated and the terminals to which resources are to be allocated under the carrier according to the order of the terminal ID sets allocated under the carrier; S77, if the priority of the terminal with allocated resources under the allocated carrier is higher than the priority of the terminal with resources to be allocated, compare the priority of the next terminal with allocated resources; otherwise, send the terminal ID to the ground station model; S78. Repeat steps S76-S77. If the application requirements of the terminals to be allocated resources cannot be met after releasing all time slot resources under the allocated carrier, it is determined that the resource allocation has failed.

8. A satellite communication system resource allocation mode lightweight reconfigurable modeling system according to claim 5, characterized in that: The method for determining the cross-link relationship of the forwarders comprises the following steps: S81. According to the resource application information sent by the terminal model, the applied uplink beam is obtained, and in combination with the resource pool information sent by the ground station model, all transponder resource pools under the applied uplink beam are traversed; it is determined whether there is a transponder with remaining bandwidth resources, if not, it is determined that the crosslink fails; if so, the transponder with the most remaining resources is obtained and determined as the uplink transponder ID; S82. According to the resource application information sent by the terminal model, the applied downlink beam is obtained, and the resource pools of all transponders that meet the cross-link relationship under the applied downlink beam are traversed in combination with the cross-link relationship sent by the satellite model and the resource pool information sent by the ground station model; it is determined whether there are transponders with remaining bandwidth resources or transponders that meet the cross-link relationship under the downlink beam. If not, it is determined that the cross-link fails; if so, the transponder with the most remaining resources is obtained and determined as the downlink transponder ID; S83: Determine the uplink transponder ID and the downlink transponder ID as the applied transponder IDs.

9. A satellite communication system resource allocation mode lightweight reconfigurable modeling system according to claim 5, characterized in that: The resource release method comprises the following steps: S91. Acquire a carrier corresponding to the carrier resource ID to be released according to the carrier resource ID information to be released sent by the ground station model; S92, according to the time slot to be released and the carrier resource ID information sent by the ground station model, traverse the time slot ID corresponding to the carrier, and obtain the time slot with the same ID number as the time slot to be released; S93: Release the carrier and time slot resources.
