Description

Communication control method, network device, network system, and storage medium Technical Field The present disclosure relates to the field of communications technologies, and in particular, to a communication control method, a network device, a network system, and a storage medium. Background In the current 3GPP standard specifications, NTN satellites support only transparent forwarding modes, including transparent forwarding between ground terminals and ground base stations, or between ground base stations and a ground core network. However, due to geographical location limitations, NTN (Non Terrestrial Network, non-terrestrial network) gateway stations cannot be widely deployed, resulting in coverage limitations. Therefore, the 3GPP SA2 considers the satellite reproduction mode in the R19 stage, namely the base station and/or (part of) the core network are/is functional, thereby reducing the dependence on the ground network, realizing flexible networking and reducing the communication delay. In view of the terrestrial gateway station deployment limitations, the satellite-to-terrestrial connection may be intermittently/temporarily unavailable, such as when the satellite is servicing terminals under its coverage, the satellite is disconnected from the terrestrial feeder link. Store-and-forward operations may be provided for delay tolerant/delay insensitive traffic. Specifically, for uplink, "store" refers to storing uplink information from a UE (User Equipment) on the satellite, and "forward" refers to forwarding the stored uplink information to the ground network. For downlink, "store" refers to storing downlink information from the terrestrial network on the satellite, and "forward" refers to forwarding the stored downlink information to the UE.
