Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202310832362.6, filed with the China National Intellectual Property Administration on July 7, 2023, entitled "Information Transmission Method, Apparatus, Terminal, and Network Device," the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the field of satellite communication technologies, and in particular to an information transmission method, apparatus, terminal, and network device. BACKGROUND In a satellite-based store-and-forward scenario, a satellite storage device allocates storage space of a specific capacity (also referred to as store-and-forward space) for a User Equipment (UE) based on its request for storing data. Typically, this storage space of a specific capacity is valid for a specific period, which is generally the maximum validity period of the storage space serving the UE. When the specific period allocated for the UE expires, the storage space of that specific capacity will be released. It is also important to note that if the satellite storage device cannot allocate storage space for a newly requesting UE, it will affect the provision of storage services for this UE. In actual operation, when the satellite device re-establishes a link with a ground device to forward data stored in the satellite storage device, or when the uplink connection on the UE side is restored to complete data reception, or when stored data expires and is discarded, the storage space of that specific capacity will be in an idle state with no cached data. Therefore, how to efficiently utilize the aforementioned storage space of a specific capacity is key to improving storage space utilization, meeting the store-and-forward demands of more UEs, and providing high-quality satellite-based store-and-forward services. SUMMARY Embodiments of the present disclosure provide an information transmission method, apparatus, terminal, and network device, to improve storage space utilization to meet the store-and-forward demands of more UEs and provide high-quality satellite-based store-and-forward services.
