In some embodiments, fig. 1B is a schematic diagram of a satellite communications architecture, shown in accordance with an embodiment of the present disclosure. As shown in fig. 1B, a satellite in the satellite access network supports the gNB function; the satellite establishes a communication connection with the UE via a service link and the satellite establishes a communication connection with the ground station via a feeder link. The satellite access network is respectively connected with the core network and the UE; the core network includes an MME, an S-GW, and a packet data network gateway (Packet Data Network Gateway, P-GW). The core network is connected with the data network. Alternatively, the ground station may be a ground receiving station. Alternatively the UE may be the terminal in the previous embodiment.
In some embodiments, the satellite access network may not provide continuous coverage services due to problems such as insufficient number of satellite deployments, limited coverage, etc. Such discontinuous coverage includes: there are intermittent situations in the service link (service link) between the satellite and the UE or in the feeder link (service link) between the satellite and the ground station.
In some embodiments, mobility enhancement, power saving techniques, etc. in the case of discontinuous coverage are presented for the case of discontinuous coverage of a service link.
In some embodiments, for the case of discontinuous coverage of the feeder link, although the communication requirement that delay tolerant services need to be supported in the case where the feeder link cannot provide a continuous connection has been proposed, there is currently no technology that clearly how to support the services.
In some embodiments, for the case of a feeder link outage (when the satellite is disconnected from the ground station), a satellite access network is proposed to support the data storage and forwarding functions to enable traffic communication in the case of a feeder link outage.
For example, FIG. 1C is a schematic illustration of a satellite mode of operation; as shown in fig. 1C, in the "normal satellite operation" mode, signaling and data interaction between the UE and the satellite access network, the terrestrial core network, requires simultaneous activation of the service link and the feeder link, so that the UE can interact with the satellite through the service link. There is a continuous end-to-end connection path between the UE, satellite and terrestrial networks.
For example, FIG. 1D is a schematic illustration of another satellite mode of operation; as shown in fig. 1D, the end-to-end interaction of signaling/data is split into two processes (step a and step B), which may not run simultaneously: in step a, the UE performs signaling/data interaction with the satellite, where no connection is required between the satellite and the terrestrial network (i.e., the satellite runs the service link, but there is no active feeder link); in step B, the connection of the feeder link between the satellite and the ground network is established for signaling/data interaction, and satellite movement changes from establishing the service link in step a to establishing the feeder link connection in step B.
In some embodiments, satellite operations supporting store and forward functionality are particularly well suited for delay tolerant services or non-real-time internet of things satellite services deployed over non-stationary orbit (NGSO) satellite access networks. For example, during periods when the feeder link is not available, uplink data and/or signaling may be stored in the base station and downlink data and/or signaling may be stored in the core network device (e.g., S-GW, MME). Once the feeder link is available, the stored data and/or signaling may be forwarded to the remote peer (e.g., stored uplink data and/or signaling may be forwarded from the base station to the core network device or stored downlink data and/or signaling may be forwarded from the core network device to the base station).
However, there is no provision for how to store data and how to forward data using satellite access with intermittent or temporary satellite connections to support delay tolerant traffic.
