[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0051] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0052] Figure 1 FIG. 1 is a system architecture diagram of a satellite communication network according to an exemplary embodiment. Figure 1 As shown, the system includes a user side, a satellite core network and a ground core network.

[0053] The user side includes UE (User Equipment), which includes but is not limited to mobile phones, smart terminals, multimedia devices, streaming media devices, etc. UE is a basic component of the 5G network architecture. It includes not only devices directly used by users, such as smart phones, but also other types of smart terminal devices.

[0054] The satellite core network includes RAN (Radio Access Network). RAN is a key element in the mobile communication system architecture and acts as a channel for transmitting information between user equipment (UE) and the core network. In 5G networks, RAN is called NG-RAN (next generation radio access network), where gNB acts as an access node (the corresponding physical entity is a base station) and provides services to terminals by using user plane and control plane protocols.

[0055] The ground core network includes UDM (Unified Data Management), AMF (Access and Mobility Management Function), NSSF (Network Slice Selection Function) and NWDAF (Network Data Analytics Function). AMF is one of the 5G core network elements, which is mainly responsible for the access and mobility management of user terminals UE, and specifically handles UE access control, including UE identity authentication, security policies, mobility management, etc. In addition, AMF is also responsible for establishing and maintaining a secure tunnel between UE and SMF (session management function) to ensure the secure transmission of data.

[0056] NSSF is mainly responsible for providing services during the network slice selection process. In 5G networks, NSSF plays a vital role, especially in the management and selection of network slices. Network slicing is a mechanism that virtualizes physical network resources into multiple independent virtual networks, each of which can meet specific business needs. NSSF retrieves and provides information about allowed network slices (Allowed NSSAI, Configured NSSAI), target AMF sets or lists of candidate AMFs through a series of service operations, such as NSSelection services, to ensure that user equipment (UE) can access the network slice that best suits its needs.

[0057] As an important part of the 5G core network architecture, NWDAF is responsible for data collection, model training, reasoning and intelligent prediction, and outputs analysis results for network, network management and application execution policy decisions. The working principle of NWDAF is to collect data from multiple network functions, such as user experience data, wireless resource data, etc., and then analyze the data intelligently, identify traffic types and detect user experience in real time, and generate QoS (quality of service) strategies, so as to fully guarantee the differentiated experience of users in the 5G era.

[0058] In such Figure 1In the network architecture shown, for sparsely populated areas, a longer SSB cycle is generally configured to put the base station in a deep sleep state, thereby achieving the purpose of reducing base station power consumption for energy saving. That is, the SSB cycle is generally adjusted only by the number of users, regardless of the specific service type of the user. If the number of users is small, a longer SSB cycle is configured to facilitate energy saving. However, in the ocean or polar regions, the number of users is very small, but some scientific expedition teams need real-time navigation or interaction with data centers, which requires low latency. Therefore, the SSB cycle cannot be blindly lengthened due to the small number of users, resulting in the inability to conduct sensitive experiments and services. Based on this, Figure 2 The method flow chart of a synchronization signal block period adjustment method according to an exemplary embodiment is shown. The method is executed by a network data analysis function NWDAF; the method includes:

[0059] Step 201, send a slice service type request to the terminal device, and receive slice information sent by the terminal device.

[0060] In the 5G network, after powering on, the UE will send a registration request to the AMF to complete the 5G network registration. During this process, the UE needs to send a slice information request, and the slice information corresponding to the slice information request is still stored on the terminal device UE after the 5G network registration process is completed.

[0061] If the SSB cycle needs to be adjusted at this time, the network data analysis function NWDAF can send a slice service type request to each terminal device, thereby requesting the slice information of each terminal device UE registered in the 5G network.

[0062] Optionally, in an embodiment of the present application, the slice information includes a service type of the terminal device UE, and the service type is used to indicate the type of service performed by the terminal device.

[0063] Step 202: Perform a service type ratio analysis on the slice information received from each terminal device, and send the analysis result to the radio access network RAN ​​on the satellite to adjust the SSB period of the radio access network RAN.

[0064] In one possible implementation, when in the analysis results, when the proportion of slice information of service types uRLLC and HDLLC high data rate and low latency communication exceeds a specified threshold, the SSB cycle is set to low latency mode.

[0065] When the proportion of terminal devices UE with service types of high reliability and low latency communication uRLLC and high data rate and low latency communication HDLLC is high, the terminal devices in the area have high requirements for latency. Therefore, in order to ensure the quality of communication, even in maps with low user density, a shorter SSB cycle should be set to ensure that the terminal devices in the map can handle the business normally. Correspondingly, when the proportion is low, most of the terminal devices in the area do not have high requirements for latency. Therefore, the SSB cycle can be set longer to reduce the consumption of communication resources.

[0066] In summary, the network data analysis function NWDAF terminal device sends a slice service type request, receives slice information sent by the terminal device, and performs a service type ratio analysis on the slice information of each terminal device, and then sends the analysis result to the radio access network RAN ​​on the satellite. The radio access network RAN ​​adjusts the SSB cycle of the radio access network RAN ​​based on the ratio analysis result. The above scheme dynamically adjusts the SSB cycle according to the service type in the slice requested by the above UE. Even in areas with low user density, if there is a high proportion of users requiring low-latency services, a shorter SSB cycle is set, which balances the communication quality and communication overhead in sparsely populated areas.

[0067] Figure 3 The present invention is a method flow chart of a synchronization signal block period adjustment method according to an exemplary embodiment. The method is executed by a network data analysis function NWDAF; the method is executed by a radio access network RAN ​​on a satellite, and the method includes:

[0068] Step 301, obtain the analysis result sent by the network data analysis function NWDAF; the analysis result is obtained by the network data analysis function NWDAF performing a service type ratio analysis on the slice information received from each terminal device.

[0069] Specifically, in an embodiment of the present application, the network data analysis function NWDAF will analyze the slice information uploaded by each terminal device UE, determine the service type of each terminal device UE registered in the area, and perform a proportion analysis on the service type of each terminal device UE to determine which service types in the area have a relatively large proportion, and send the analysis results of the proportion analysis to the wireless access network RAN.

[0070] Step 302: Adjust the SSB period of the radio access network RAN ​​according to the analysis result.

[0071] In a possible implementation, the wireless access network RAN ​​obtains the proportion of slice information of service types of high reliability and low latency communication uRLLC and HDLLC high data rate and low latency communication in the analysis results; if the proportion of slice information of service types of high reliability and low latency communication uRLLC and HDLLC high data rate and low latency communication in the analysis results exceeds a specified threshold, the SSB period is set to a low period.

[0072] Specifically, the SSB period is configured according to the terminal service type in the area. Since the satellite is moving, the SSB period of the satellite beam changes dynamically at different times.

[0073] In the 3G era, terminal services are classified according to their different requirements for latency and packet loss rate:

[0074] Conversational: Voice and video calls are latency-sensitive services with high latency requirements.

[0075] Streaming media: online music and videos, which are one-way transmissions with low latency requirements;

[0076] Interactive: web browsing, games, etc., with low latency requirements;

[0077] Background: email, text messages, etc., with low latency requirements.

[0078] There are three common business scenarios in the 5G era:

[0079] Enhanced Mobile Broadband (eMBB): It needs to focus on indicators such as peak rate, capacity, spectrum efficiency, mobility, and network energy efficiency, which is similar to traditional 3G and 4G.

[0080] Massive Machine Type Communication (mMTC): focuses on the number of connections and is less concerned with indicators such as download rate and mobility.

[0081] Ultra-reliable and low-latency communication (uRLLC): focuses on high reliability, mobility, and ultra-low latency, and does not have much demand for indicators such as the number of connections, peak rate, capacity, spectrum efficiency, and network energy efficiency.

[0082] According to the definition in 3GPP, the values ​​of the six service types are:

[0083]

[0084] Table 1. Service type values

[0085] The above table includes two low-latency services, namely uRLLC and HDLLC, and the SST values ​​are 2 and 6 respectively.

[0086] In the NR NTN scenario, to identify the service type, it is necessary to collect the terminal's slice information, namely S-NSSAI (Single Network Slice Selection Auxiliary Information), which is one of the core parameters of 5G network slicing and is used to identify a specific network slice. S-NSSAI consists of two parts, SST (Slice / Service type) and SD (Slice Differentiator). SST is the slice / service type, which refers to the expected network slice behavior in terms of functions and services.

[0087] Slice number SST SD 00001 1 128-255 00002 2 128-255 00003 2 128-255 00004 4 128-255 00005 6 128-255 00006 6 128-255

[0088] Table 2. Slice / Serving Types

[0089] According to the service type values ​​in Table 1, identify and count the number of slices with SST values ​​of 2 and 6 and the number of all slices;

[0090] Calculate the proportion of slices with values ​​of 2 and 6 in all slices. When the proportion exceeds 50%, the service under the beam is considered to be a low-latency service area. In this case, even in areas with low user density, there is no need to set a higher SSB period. Instead, a relatively low SSB period should be set based on delay sensitivity.

[0091] In a possible implementation, each time the satellite switches its beam, the number of terminal devices registered in the network under the beam of the satellite is obtained; and based on the number of devices, the initialization SSB period of the satellite is determined.

[0092] Further, when the number of the devices is greater than a threshold, the low period is determined as the initialization SSB period of the satellite;

[0093] When the number of devices is less than or equal to a threshold, a high period is determined as an initialization SSB period of the satellite.

[0094] That is to say, in the embodiment of the present application, the SSB cycle needs to be initialized first, and the basis for initialization is the number of terminal devices in the area. If the number of terminal devices in the area is high, it can be directly set to a smaller SSB cycle to ensure the communication quality of the terminal devices in the area; if the number of terminal devices in the area is low, it can be set to a larger SSB cycle to reduce the consumption of communication resources, and then the SSB cycle can be adaptively adjusted according to the service type of the terminal devices in the area.

[0095] Please refer to Figure 4 , which shows a schematic diagram of a process of collecting slice information and analyzing it by a terminal according to an embodiment of the present application. Figure 4 As shown, the process includes the following steps:

[0096] 1. The UE sends a registration request, which carries "requested NSSAI", "network slice indication", "5GS registration type", etc.;

[0097] 2.AMF requests the UE's slice selection subscription data from UDM to decide whether to reroute the UE's registration request;

[0098] 3. The UDM provides slice selection subscription data upon request from the AMF, including the S-NSSAIs applicable to the subscription of the PLMN and an indication of whether each S-NSSAI is the default S-NSSAI;

[0099] 4. If the AMF cannot serve the UE that sent the Registration Request, the AMF queries the NSSF with various information, including the "Requested NSSAI", "Default Configured NSSAI" indication, the mapping of the "Requested NSSAI" to the HPLMN S-NSSAI, the "Subscribed S-NSSAIs" (with an indication if it is marked as the default S-NSSAI), any "Allowed NSSAs" of other access types that may have (including their mapping to the HPLMN S-NSSAI), the PLMNID of the SUPI and the current tracking area of ​​the UE;

[0100] 5. The NSSF returns to the initial AMF the mapping of each S-NSSAI of the "Allowed NSSAI" and the optional "Allowed NSSAI" to the "Subscribed NSSAI";

[0101] 6.AMF forwards the registration acceptance message to the UE, indicating that the registration request has been accepted;

[0102] 7. The NWDAF requests the UE for information related to the slices obtained by the UE in the above steps;

[0103] 8.UE sends slice information to NWDAF;

[0104] 9. After receiving the slice information, NWDAF performs service type ratio analysis.

[0105] If the SSB period is set only considering the number of users, poor communication quality may result when the number of users is small. Therefore, in the above solution, the service type requested by the user is determined by obtaining the slice parameters requested by the user, and the proportion of each service type to all service types is counted. If it is found that most services require low latency, then even in areas with low user density, a lower SSB period should be set to ensure the service experience of these users.

[0106] In summary, the network data analysis function NWDAF terminal device sends a slice service type request, receives slice information sent by the terminal device, and performs a service type ratio analysis on the slice information of each terminal device, and then sends the analysis result to the radio access network RAN ​​on the satellite. The radio access network RAN ​​adjusts the SSB cycle of the radio access network RAN ​​based on the ratio analysis result. The above scheme dynamically adjusts the SSB cycle according to the service type in the slice requested by the above UE. Even in areas with low user density, if there is a high proportion of users requiring low-latency services, a shorter SSB cycle is set, which balances the communication quality and communication overhead in sparsely populated areas.
