example 1

[0071] Example 1: Inter-satellite computing information exchange process based on request

[0072] LEO2 obtains the computing status information of LEO1 based on the requested inter-satellite computing information exchange process, which is specifically implemented through the following steps:

[0073] Step 1-1: LEO1 establishes the calculation load information table

[0074]LEO1 obtains the current computing load information table through historical data statistics in one or more satellite operation cycles, as shown in the following table:

[0075] Table 4-1 Computing load information table of LEO1 (based on computing load status)

[0076] period 0-0.5h 0.5h-1h 1h-1.5h 1.5h-2h Calculate load status 0.9 0.2 0 0.6

[0077] Table 4-2 Compute Load Information Table for LEO1 (Based on Compute Load Level Indication)

[0096] Example 2: Inter-satellite computing information exchange process initiated by satellites

[0097] In the specific implementation steps of the computing load status information actively reported by LEO1 to GEO, the difference from Example 1 is that steps 1-2 and 1-3 of Example 1 are replaced by the following steps 2-2, and other steps are the same as those of Example 1. same.

[0098] Step 2-2: LEO1 actively reports a calculation load information table message to GEO, the message includes: the calculation load information table of LEO1, the total calculation resource C used by LEO1 for the calculation task tot .

[0099] All or part of the steps for implementing the above method embodiments may be completed by hardware related to computer programs. Based on this understanding, the present invention also provides a computer program product comprising one or more computer instructions. The computer instructions may be stored in a computer-readable storage medium. The ...

Abstract

The invention provides a method for interacting with calculation information between satellites, which comprises the following steps that: a satellite 1 establishes a calculation load information table which is used for representing calculation load states of the satellite 1 in different time periods in a satellite operation period; the satellite 1 provides the calculation load information table and the total calculation resource of the satellite 1 for the calculation task to a satellite 2; the satellite 2 sends a signaling for confirming calculation of the load information table to the satellite 1 after receiving successfully; the satellite 1 generates a correction information table after receiving the signaling, wherein the correction information table is used for representing the changeof the calculated load state of the satellite 1 in different time periods in the satellite operation period; the satellite 1 sends the generated correction information table to a satellite 2; and thesatellite 2 sends a signaling for confirming the correction information table to the satellite 1 after successfully receiving, and updates and calculates the load information table according to the correction information table. Important calculation load state information is provided for inter-satellite calculation resource sharing and calculation task cooperation, and effective signaling and step design are provided for inter-satellite calculation load state information interaction.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for interacting computing information between satellites and a method for generating an applied information table. Background technique [0002] The satellite communication network can make up for the insufficient coverage of the terrestrial communication network and realize the global stereoscopic coverage without blind spots. With the emergence of a large number of new space services such as satellite Internet of Things and satellite multimedia, in addition to the demand for satellite communication resources, the requirements for satellite computing resources are also getting higher and higher. With the rapid development of spaceborne satellite computing platform technology, satellite computing resources and computing capabilities have been greatly improved. However, due to the geographical and time-domain non-uniform characteristics of wide-area comput...
