Wave position: a satellite mobile communication system or a terrestrial area in which a beam is directed in a terrestrial mobile communication system.

The method is applied to a star-ground fusion network, and the star-ground fusion network can be built by adopting the existing star-ground fusion core network architecture. Referring to fig. 1, the so-called star-to-ground converged network may comprise a user terminal UE, a base station BS, an access and mobility management function network element AMF, and a network data analysis network element NWDAF, the UE and BS may be one or more. Specifically, the UE referred to in the present invention may refer to either one of the terrestrial mobile communication system user terminal UE _t or the satellite mobile communication system user terminal UE _s as shown in fig. 1. The BS referred to in the present invention may refer to either one of the ground mobile communication system base station BS _t or the satellite mobile communication system base station BS _s as shown in fig. 1. The satellite gateway of the satellite mobile communication system base station BS _s and the ground mobile communication system base station BS _t are connected into an AMF in the satellite-ground fusion core network by adopting the satellite-ground fusion core network architecture, and the AMF is connected with an NWDAF in the satellite-ground fusion core network, and the NWDAF is further connected to a database.

In fig. 1, a terrestrial mobile communication system is configured among all BSs _t and all UEs _t. All BSs _s and all UEs _s form a satellite mobile communication system.

For ease of understanding, the following description will be given by taking a plurality of UEs and a plurality of BSs as examples. It is noted that the plurality of so-called UEs includes at least one of the above-mentioned so-called UE _t and one so-called UE _s; the plurality of so-called BSs includes at least one of the so-called BSs _t and one of the so-called BSs _s.

In the present invention, each BS is configured with one or more wave bits for a corresponding UE. Specifically, each BS _t may configure one or more wave bits for each UE _t in its cell. Each BS _s may configure one or more wave positions for its respective UE _s with which the phased array hops are associated. In the star-to-ground fusion network, the number of wave numbers configured by each BS _t and each BS _s is the same.

Further, the invention provides a spectrum resource allocation method applied to the star-ground fusion network shown in fig. 1. Referring to fig. 2, a flow chart of a spectrum resource allocation method provided by the present invention is described in terms of BS in a star-to-ground fusion network as described above, and specifically includes:

s201: the BS determines a traffic load scenario for one or more wave bits.

For convenience of description, a BS is illustrated as an example, and the BS may be any BS _t or any BS _s in a star-to-ground fusion network. In particular, so-called one BS determines the traffic load scenario for one or more of the wave bits, i.e. so-called one BS determines the traffic load scenario for each wave bit it configures.

Alternatively, the BS may determine the traffic load scenario for one or more wave bits in two ways:

mode 1: the BS determines a traffic load scenario for one or more of the wave bits based on the configured number of wave bits and BS sampling frequency.

In mode 1, the BS determines a corresponding traffic load scenario by combining the configured number of wave bands with the BS sampling frequency. It can be appreciated that when the so-called BS is embodied as BS _t in a star-to-ground converged network, it is the corresponding traffic load scenario that is determined by its number of configured wave bands for each UE _t in combination with its own BS _t sampling frequency. When the BS is specifically a BS _s in a star-to-ground converged network, it is the corresponding traffic load scenario that is determined by the number of allocated wave bits for each UE _s in combination with its own BS _s sampling frequency. All subsequent BSs of the present application may be divided into BS _t and BS _s, and are not described in detail for convenience of understanding.

The specific discriminant of the BS determining the traffic load scenario in mode 1 is as follows:

Num_Beam*Frequency_BS≥th1

Here, num _Beam refers to the number of wave bits configured by the BS, frequency _BS refers to the BS sampling Frequency, and th1 refers to a first discrimination threshold set by the pointer for the traffic load scenario.

In mode 1, when the value of the left discriminant is greater than or equal to the set first discriminant threshold, the traffic load scenario of the BS is determined to be a large traffic load scenario. Otherwise, when the value of the left discriminant is smaller than the set first discriminant threshold, determining that the traffic load scene of the BS is a light load scene.

Optionally, in mode 1, the BS may also send a local handover command to NWDAF through the AMF to transfer the corresponding traffic load scenario determined by the BS to NWDAF.

Mode 2: the BS determines, in response to the global scenario switching instruction sent by NWDAF, a traffic load scenario for one or more slots based on the global to-be-switched scenario indicated by the global scenario switching instruction.

Optionally, in mode 2, after sending the global scenario switching instruction to the BS through the AMF at NWDAF, the BS may determine, in response to the global scenario switching instruction, a corresponding traffic load scenario based on the global to-be-switched scenario indicated by the global scenario switching instruction. Wherein: the global to-be-switched scenario is determined by the NWDAF based on the number of wave bits of each of at least one target BS and the BS sampling frequency of each of the at least one target BS, where the target BS is any BS associated with the NWDAF.

In this embodiment, the at least one target BS may refer to all BSs associated with NWDAF in the star-to-ground fusion network, or may be individual BSs manually selected by those skilled in the art from all BSs according to actual needs, which is not limited.

The specific discriminant of NWDAF for determining the traffic load scenario in mode 2 is as follows:

Wherein, Refers to the number of wave bits of the ith target BS,/>Refers to BS sampling frequency of the ith target BS, N refers to the number of target BSs, and th2 refers to a second discrimination threshold set for the traffic load scenario by the pointer.

In mode 2, when the value of the left discriminant is greater than or equal to the set second discriminant threshold, it is determined that the global to-be-switched scene is a large traffic load scene. Otherwise, when the value of the left discriminant is smaller than the set second discriminant threshold, determining that the global scene to be switched is a light load scene.

In the present application, the first discrimination threshold and the second discrimination threshold may or may not coincide. There is no limitation in this regard.

Optionally, before responding to the spectrum resource scheduling request sent by the target UE, the BS may acquire uplink channel measurement data of each associated UE, and receive downlink channel measurement data sent by each associated UE, and then generate a summary report for one or more wave bits at least according to each uplink channel measurement data, each downlink channel measurement data, and the traffic monitoring data of the BS. And then, sending a summary report to the AMF or NWDAF according to a data acquisition rule preset corresponding to the service load scene.

Specifically, the BS may obtain uplink channel measurement data of each UE associated with the BS through a Sounding reference signal (english: sounding REFERENCE SIGNAL, abbreviated as SRS) transmitted to the BS by each UE associated with the BS. The BS may also obtain downlink channel measurement data of each UE associated by transmitting a channel state Information reference signal (english: CHANNEL STATE Information-REFERENCE SIGNAL, abbreviated as CSI-RS) or a channel state Information interference level measurement (english: CHANNEL STATE Information-INTERFERENCE MEASUREMENT, abbreviated as CIS-IM) to each UE associated. Wherein each UE associated with the BS, e.g., a respective UE in the coverage of the BS.

In the embodiment of the present application, the SRS, CSI-RS and CSI-IM may be configured periodically, and a single port SRS, CSI-RS and CSI-RM occupy one Resource Element (RE) on each Resource block. In order to avoid collision with other physical channels or physical signals, the configuration of SRS, CSI-RS and CSI-RM utilizes multiplexing of RE time, frequency and code domains, so that the sounding reference signal of the UE in the application cannot collide with the following signals: a. any set of control resources (including SRS, CSI-RS, CSI-IM, etc.) configured for the terminal and other terminals in the region; b. demodulation reference signals related to PDSCH, PUSCH transmissions; c. synchronization signal block SSB.

Further, the traffic monitoring data of the so-called BS includes at least: physical resource block, PRB, usage of the BS and radio resource control, RRC, connection number of the BS. Optionally, the service monitoring data further includes: base station parameters of the BS, such as base station location, frequency band used, etc. In practical application, the BS base station industrial parameter can generate a corresponding summary report by combining uplink channel measurement data, downlink channel measurement data and service monitoring data of the BS when updating; when not updated, corresponding summary reports are generated only according to the uplink channel measurement data, the downlink channel measurement data and the service monitoring data of the so-called BS.

Optionally, the BS may send the summary report to the AMF or NWDAF according to the data collection rule preset corresponding to the traffic load scenario in two ways:

mode 1: the BS sends a summary report to the AMF according to a first data acquisition rule preset corresponding to the light load scenario, and instructs the AMF to send the summary report to NWDAF.

Mode 2: the BS sends application interaction information to the AMF according to a second data acquisition rule preset corresponding to the large service load scene, wherein the application interaction information is used for indicating the AMF to create the connection between the BS and NWDAF; the BS sends a summary report to NWDAF over the connection between the BS and NWDAF.

S202: and the BS responds to the frequency spectrum resource scheduling request sent by the target UE, and sends transfer request information to the AMF or NWDAF according to a transfer request rule preset corresponding to the service load scene.

Specifically, the target UE refers to any UE associated with a BS, such as any UE _t within the coverage area of the BS _t or any UE _s within the coverage area of the BS _s.

Optionally, the BS may send the transfer request information to the AMF or NWDAF according to a transfer request rule preset corresponding to a traffic load scenario in the following two ways:

Mode 1: the BS transmits transfer request information to the AMF according to a first transfer request rule preset corresponding to the light load scenario, and instructs the AMF to transmit the transfer request information to NWDAF.

Mode 2: the BS sends or does not send application interaction information to the AMF according to a second transmission request rule preset corresponding to the large service load scene, wherein the application interaction information is used for indicating the AMF to establish the connection between the BS and NWDAF; the BS transmits transfer request information to NWDAF through a connection between the BS and NWDAF.

Corresponding to the large traffic load scenario, the BS may send or not send the application interaction information to the AMF according to a preset second delivery request rule, and then send the delivery request information to NWDAF. For example, the BS may transmit the application interaction information to an appropriate one of the AMFs, so that after the AMFs reply, the delivery request information is transmitted to NWDAF. Or the BS may request to create a connection to the same AMF in S201, and may directly send a transfer information request to NWDAF without sending the application interaction information.

S203: the BS receives the spectrum resource allocation scheme sent by the AMF or NWDAF corresponding to the transfer request information, and allocates the corresponding spectrum resource to the target UE according to the spectrum resource allocation scheme.

In particular, the BS may receive a spectrum resource allocation scheme corresponding to the transfer request information forwarded from NWDAF through the AMF. Or the BS may also receive NWDAF a spectrum resource allocation scheme corresponding to the transmission of the transfer request information.

Based on the above manner, the present application supports the BS to respond to the spectrum resource scheduling request sent by the target UE according to the preset delivery request rule corresponding to the service load scenario, and sends the delivery request information to the AMF or NWDAF. When the BS receives the spectrum resource allocation scheme sent by the AMF or NWDAF corresponding to the transfer request information, the BS allocates the corresponding spectrum resource to the target UE according to the spectrum resource allocation scheme, so as to improve the spectrum resource utilization rate and solve the problems of traffic burst and the like in the satellite-to-ground user shared spectrum scene.

In particular, the above-described procedure may have four possible interactions between BS, UE, AMF and NWDAF in a star-to-ground converged network. For convenience of description, it will be referred to as interaction 1 to interaction 4. These four interactions will be described in detail below.
