In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

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.

The information processing method provided by the embodiment of the disclosure can comprise the storage of data and/or the forwarding of the data.

In some embodiments, the storing of the data may include: in case it is detected that a feeder link or satellite connection is not available, the MME determines to store downlink data. The downlink data, i.e., the data in the following embodiments.

Optionally, the data comprises signalling and/or user plane data. For example, the signaling may include at least one of: EPC connection management signaling, EPC session management signaling, and EPC mobility management signaling. The signaling may be signaling related to service acceptance, tracking area update acceptance, routing area update acceptance, and/or IP-can sessions. Illustratively, the user plane data is related to traffic data. The user plane data may be transmitted through a user plane (i.e., a connection between a base station and an S-GW) or a control plane (i.e., a connection between a base station and an MME).

Alternatively, the signaling may be the first signaling in the previous embodiment; the user plane data may be the first data in the previous embodiments.

Optionally, the following results may be determined for signaling: store signaling or reject signaling. For example, whether to store the signaling or reject the signaling may be determined based on a procedure to which the signaling belongs. For example, if the signaling is an attach accept belonging to an attach procedure, determining to reject the signaling; as storing the attachment signaling is not meaningful.

Optionally, the following results may be determined for the user plane data: store user plane data or discard user plane data. For example, whether to store user plane data or discard user plane data may be determined based on user subscription information and/or traffic type, etc. For example, if the storage capacity of the user plane data exceeds the storage capacity indicated by the subscription of the user, or the user plane data is not data of delay tolerant traffic, it is determined to discard the user plane data.

Alternatively, the data may be stored at the MME or the serving gateway.

Illustratively, the MME stores data. For example, the signaling may be stored at the MME. As another example, user plane data may be stored at the MME.

Illustratively, the S-GW stores data. For example, user plane data may be stored at the S-GW. As another example, the MME provides the determined data storage information to the S-GW. The data storage information may include a storage duration indicating how long the data should be stored and a capacity indicating the data can be stored. Alternatively, the data storage information may be the first indication information in the previous embodiment; the storage duration is the first time in the previous embodiment; the capacity may be the first capacity in the previous embodiment.

Optionally, during the feeder link outage, the MME stores the S1 application protocol (S1 Application Protocol, S1 AP) of the UE and/or the bearer context of the UE. The base station stores the S1 AP of the UE and/or the bearer context of the UE. Alternatively, the UE may be the terminal in the previous embodiment.

In some embodiments, the forwarding of data may include: in case it is detected that a feeder link or satellite connection is available, the MME determines the forwarding of downlink data. Alternatively, if the MME detects that a satellite connection becomes available, the MME uses the S1 AP of the UE and/or the bearer context of the UE to resume connection with the base station (i.e., resume connection of the feeder link). The downlink data, i.e., the data in the following embodiments.

Optionally, for data stored at the S-GW, at least one of the following may be performed: the MME notifies the G-GW to forward the stored data if the satellite connection is detected to be available; the S-GW forwards the stored data based on the data store information received from the MME (e.g., if the store duration expires, the S-GW forwards the stored data); and the S-GW forwarding data may be forwarded based on the priority of each data.
