For a better understanding of the embodiments of the present disclosure, the following describes an application scenario in wireless communication:

in one embodiment, the terminal may decide to enter a power save mode for power saving purposes during loss of current satellite access coverage, or the terminal may select other available satellite accesses as well. Therefore, when the terminal uses the satellite access with discontinuous coverage, the network needs to acquire the satellite coverage condition of the area where the terminal is located, so as to determine the behavior of the terminal during the period of losing the current satellite network signal according to the satellite coverage information, for example, determine the power saving parameter, let the terminal enter the power saving mode during the period of losing the current satellite signal, or instruct the terminal to use other available satellite access networks when losing the current satellite network signal.

In one embodiment, the radio access network can only acquire ephemeris information for 4 satellites adjacent to the current access location, and thus the ephemeris information may not be sufficient for determining terminal-related satellite coverage information, e.g., when it is desired to determine terminal-related satellite coverage information based on the motion trail of the terminal, the future designated location of the terminal is not covered by the currently broadcasted ephemeris information.

For a better understanding of the disclosed embodiments, the present disclosure is further described below by way of one exemplary embodiment:

the process involved below allows the provision and modification of satellite coverage availability information associated with a particular area and time horizon to the AMF.

Satellite coverage availability information (Sat Cover) refers to location and time information related to the expected coverage availability of satellites/satellite constellations providing discontinuous coverage.

Referring to fig. 15, an embodiment of the present disclosure provides an information transmission method, where the method includes:

the AMF may obtain sat_cover by subscribing to sat_cover from SCMF, which may refer to step 151 and step 152:

step 151, sending an nnef_satconvegeinfo_subscore message. As a prerequisite to receiving push notifications, the AMF subscribes to sat_cover notifications from SCMF, optionally via NEF, by sending nnef_satconvegeinfo_subscnibe message. The information contains location information and/or time information for obtaining sat_cover. The location information indicates that sat_cover needs to be obtained at that location. The time information indicates that sat_cover needs to be obtained at this time. At least one of the above types of information needs to be provided. The NEF sends a corresponding subscription message to the SCMF.

Step 152, send an nnef_satconvegeinfo_notify message. If Sat_cover is available in relation to the desired location and/or time, the SCMF invokes a notification procedure to notify the AMF that has subscribed to Sat_cover. If the SCMF receives an allowed delay for Sat_cover, then the SCMF will allocate the Sat_cover for the indicated time interval.

AF may provide Sat_cover to SCMF:

step 153, send nnef_satovertprovision_create/Updaterequest. The message contains location, time, sat_cover, allowed delay, AF identifier. The allowable delay is an optional parameter. If the allowed delay is included, it indicates that the Sat_cover in the request should be provided to the AMF that has subscribed to the Sat_cover using the Nnef_SatCoverageInfo_Subscribe service operation within the time interval indicated by the allowed delay.

Step 154, confirmation processing. The NEF checks if the AF is authorized to perform this request (to provide the second information) and the NEF checks if the AF is authorized to provide this sat_cover based on the operator policy.

Step 155, send NSCMF_SATCoverProvisionCreateUpdate Request. If the AF is authorized to provide Sat_cover, NEF invokes NSCMF_SATCoverProvisionCreate/Update service to provide Sat_cover to SCMF.

Step 156, SCMF authorization. The SCMF verifies that the location and/or time associated with sat_cover is consistent with the value range of interest (AMF) to the network.

Step 157, send nudr_dm_create/Update Request. If the verification is successful, SCMF calls Nudr_DM_Create/Update (location, time, sat_cover, allowed delay) to UDR.

Step 158, save_cover is stored. The UDR updates sat_cover for location and/or time.

Step 159, send nudr_dm_create/Update Response. The UDR sends a nudr_dm_create/Update response to the SCMF.

Step 160, send NSCMF_SATCOVERPROVION_CREATE/Update Response. The SCMF sends an NSCMF_SATCOVERPROVION_CREATE/Update response to the NEF.

Step 161, send NNEF_SATCOVERPROVION_CREATE/Update Response. The NEF sends an NNEF_SATCOVERPROVION_CREATE/Update response to the AF.

In addition to the access and mobility management function (AMF, access and Mobility Management Function) subscribing to sat_cover from SCMF, AMF may also call nnef_satcover_fetch service operations to obtain sat_cover:

step 162, triggering the AMF to obtain information through the nnef_satcover_fetch service operation. The AMF needs to determine the UE unavailable period based on sat_cover of the UE using satellite access with discontinuous coverage. If the Sat_cover is not available or invalid, triggering the AMF to acquire information through the Nnef_Satcover_Fetch service operation.

Step 163, send nnef_satcover_fetch. AMF calls Nnef_SatCover_Fetch to NEF.

Step 164, send nscmf_satcover_fetch. NEF calls Nscmf_SatCover_Fetch (location, time) to SCMF. Step 165, SCMF authorization. The SCMF checks whether sat_cover is valid or invalid in relation to location, time. If the information is invalid, the SCMF requests the AF to provide the corresponding Sat_cover.

Step 166, send nudr_dm_query. If a position, time-dependent sat_cover is available, the SCMF invokes nudr_dm_query (position, time) to retrieve the sat_cover from the UDR.

Step 167, send nudr_dm_query Response. The UDR provides nudr_dm_query response (location, time, sat_cover) to the NEF.

Step 168, send nscmf_satcover_fetch Response. The SCMF returns (location, time, sat_cover) to the NEF by calling the nscmf_satcover_fetch response.

Step 169, send nnef_satcover_fetch Response. The NEF replies to the AMF with Nnef_SatCover_Fetch (location, time, sat_Cover).

Step 170, AMF stores Sat_cover. And generating a UE unavailable period based on the sat_cover.
