Background

In a satellite network, if satellite access provides network services for User Equipment (UE), the satellite access may be affected by an insufficient number of satellites in a satellite chain or a satellite beam break, and the signal coverage provided to the ground may be discontinuous.

For ease of understanding by those skilled in the art, the embodiments of the present disclosure enumerate a plurality of implementations to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will appreciate that the various embodiments provided in the embodiments of the disclosure may be implemented separately, may be implemented in combination with the methods of other embodiments of the disclosure, and may be implemented separately or in combination with some methods of other related technologies; the embodiments of the present disclosure are not so limited.

For a better understanding of the technical solutions described in any embodiment of the present disclosure, first, a part of the related art will be described:

in some application scenarios, the discontinuous coverage of satellite access needs to be considered. For example, when the UE is not covered by satellite signals, the UE is in a sleep or power saving state to save power consumption of the UE; when the UE resumes the satellite signal coverage, the UE can wake up in time to reestablish connection with the network or develop services. For another example, when the network device sends signaling and/or data to the UE, it needs to determine whether the UE is reachable at the moment; if the UE is in the coverage area of the signal and the UE is reachable, the network equipment sends the signaling and/or data to the UE; if the UE is in the coverage area without signal, the network equipment caches signaling and/or data; and when the network equipment judges that the satellite signal is recovered to cover the UE, the network equipment sends the signaling/data to the UE. In summary, in case the UE uses a satellite access network and there is discontinuous coverage of the satellite access; when signaling and/or data occurs, the UE and the network equipment need to judge whether the UE is reachable or not by combining satellite coverage conditions, and communication interaction is performed only when the UE is reachable.

In one embodiment, the application function (Application Function, AF) needs to perceive the satellite coverage information of the UE. For example, before starting a service with a relatively long interaction time, the AF may acquire satellite coverage information of the UE from the network device; and determining whether to currently perform the service based on network coverage information of the UE. In this way, the situation that the UE transitions to no signal coverage before the end of the service can be reduced.

In one embodiment, the AF obtains satellite coverage information of the UE from a current serving network of the UE (e.g., public land mobile network (Public Land Mobile Network, PLMN)); and determines service related operations based on satellite coverage information of the UE. The business-related operation may be whether to conduct a business and/or when to conduct a business. However, the service network can only acquire satellite coverage information that the UE currently uses for satellite access; for example, if a handover occurs between the access network and/or the service network, the AF cannot accurately acquire satellite coverage information of the UE.

As shown in fig. 2, an embodiment of the present disclosure provides an information processing method, performed by AF, including:

step S21: transmitting a first request to a service network device, wherein the first request is used for requesting satellite coverage information of the UE;

Step S22: and receiving satellite coverage information sent by the service network equipment.

Here, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to, a cell phone, a computer, a server, a wearable device, a vehicle terminal, a Road Side Unit (RSU), a game control platform, a multimedia device, or the like.

Here, the service network device may be a logical node or a function, etc. that can be flexibly deployed in the service network, and the service network device is not limited herein.

In one embodiment, the serving network apparatus includes, but is not limited to, at least one of:

Session management functions (Session Management Function, SMF);

a policy control function (Policy Control Function, SCF);

unified data management (Unified Data Management UDM).

In another embodiment, the serving network apparatus may be, but is not limited to being: a source serving network device or a target serving network device.

Here, the source service network device is a network device of the source service network; the source service network is the service network before the service network switch occurs. The target service network is a network device of the target service network; the target service network is a service network after service network switching or access occurs. For example, if the UE is handed over from the first serving network to the second serving network; the source service network device is a network device of a first service network; the target serving network device is a network device of a second serving network.

In yet another embodiment, the serving network device may be a network data analysis function (Network Data Analytics Function, NWDAF). For example, the serving network device may be a source network data analysis function (S-NWDAF) or a target network data analysis function (H-NWDAF).

Here, the satellite coverage information may be, but is not limited to: satellite coverage time and/or satellite non-coverage time. Here, the satellite coverage period may be a period in which a certain area is covered with a satellite signal; the satellite coverage duration may also be a start time of satellite signal coverage and/or an end time of satellite signal coverage. Here, the satellite non-coverage period may be a period in which a certain area is not covered by a satellite signal; the satellite non-coverage period may also be a start time without satellite signal coverage and/or an end time without satellite signal. The satellite coverage to which embodiments of the present disclosure relate may be satellite signal coverage; satellite non-coverage may be that there is no satellite signal coverage.

In another embodiment, the satellite coverage information may be other information, and the satellite coverage duration and/or the satellite non-coverage duration may be determined according to the satellite coverage information; the satellite coverage information is not limited herein.

In one embodiment, a first request is for satellite coverage information of a UE for a first event. Here, the first event is used to indicate, but is not limited to, an event that indicates one of: satellite coverage information of the UE; and reachability information for the UE. As such, satellite coverage of the corresponding UE may be requested for the first event.

Thus, in the embodiment of the disclosure, the AF sends a first request to the serving network device, the first request being for requesting satellite coverage information of the UE; receiving satellite coverage information sent by service network equipment; this allows the AF to accurately obtain the satellite coverage information of the UE from the serving network device. Thus, the UE is facilitated to determine whether the UE has satellite signal coverage based on the satellite coverage information; therefore, when the service interaction between the network equipment and the UE is facilitated, effective service interaction can be performed according to the condition that whether the UE has satellite signal coverage or not.

For example, when it is determined that the UE does not have satellite signal coverage, the UE is put into a sleep or power saving state and/or the network device is not caused to send data and/or signaling to the UE; therefore, the power consumption and the like of the UE and the network equipment can be saved, and the probability that the UE does not monitor the data and/or the signaling sent by the network equipment is reduced. For another example, when it is determined that the UE has satellite signal coverage, the UE may be in an awake state, and/or the network device may send data and/or signaling to the UE; thereby, the probability that the UE monitors the data and/or signaling sent by the network equipment can be improved.

Here, the network device may be a logical node, a function or a device in the access network and/or the core network, etc. For example, the network device may be a base station.

The embodiment of the disclosure provides an information processing method, which is executed by AF and comprises the following steps:

Here, the current coverage time range and the next coverage time range may be time ranges of arbitrary lengths. For example, the current coverage time range, the next coverage time range may be a time range of 1 minute, 2 minutes, 10 minutes, 1 hour, and the like.

In one embodiment, the duration of the current coverage time range is the same as the duration of the next coverage time range.

In another embodiment, the duration of the current coverage time range is different from the duration of the next coverage time range.

Here, the developing service may perform a service-related operation; for example, but not limited to: receiving and/or transmitting information, etc. Here, the information includes, but is not limited to, signaling and/or data.

For example, if the AF determines that satellite signal coverage exists in the current coverage time range based on the satellite coverage duration in the satellite coverage information of the UE, determining to perform service in the current coverage time range; or if the AF determines that the satellite signal does not exist in the current coverage time range based on the satellite non-coverage time length in the satellite coverage information of the UE, determining that the service is not developed in the current coverage time range.

For example, if the AF determines that there is no satellite signal coverage in the current coverage time range based on the satellite coverage duration in the satellite coverage information of the UE, and determines that there is satellite signal coverage in the next coverage time range, it determines to perform service in the next coverage time range; or if the AF determines that the satellite signal coverage does not exist in the current time range and the satellite signal does not exist in the next coverage time range based on the satellite non-coverage time in the satellite coverage information of the UE, determining that the service is not carried out in the current time range and the service is not carried out in the next coverage time range.

As such, in the embodiments of the present disclosure, the AF may determine whether the UE may perform a service in a current coverage time range and/or a next coverage time range based on satellite coverage information of the UE; thereby improving the effectiveness of service development and saving the power consumption of the UE.
