Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] The present application will be described below with reference to embodiments:

[0033] According to one aspect of the embodiments of this application, a paging method is provided. Optionally, in this embodiment, the paging method can be applied to, for example... Figure 1 The hardware environment shown consists of server 101 and terminal device 103. For example... Figure 1As shown, server 101 is connected to terminal device 103 via a network and can be used to provide services to terminal device or applications installed on terminal device. Application 107 can be video application, instant messaging application, browser application, educational application, game application, etc. Database 105 can be set up on the server or independently of the server to provide data storage services for server 101, such as a game data storage server. The network mentioned above can include, but is not limited to, wired networks and wireless networks. The wired network includes local area networks, metropolitan area networks, and wide area networks. The wireless network includes Bluetooth, WIFI, and other networks that enable wireless communication. Terminal device 103 can be a terminal configured with an application, and can include, but is not limited to, at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), laptops, tablets, handheld computers, MID (Mobile Internet Devices), PADs, desktop computers, smart TVs, smart voice interaction devices, smart home appliances, vehicle terminals, aircraft, virtual reality (VR) terminals, augmented reality (AR) terminals, mixed reality (MR) terminals, and other computer devices. The server mentioned above can be a single server, a server cluster composed of multiple servers, or a cloud server.

[0034] Combination Figure 1 As shown, the paging method described above can be executed by an electronic device, which can be a terminal device or a server. The paging method can be implemented by the terminal device or the server separately, or by the terminal device and the server together.

[0035] The above is merely an example, and this embodiment does not impose any specific limitations.

[0036] Alternatively, as an optional implementation, such as Figure 2 As shown, the paging method described above includes:

[0037] S202, Receive frequency band information transmitted by satellite base station, wherein, if the number of spectrum bandwidths of satellite base station meets the first condition, the frequency band information includes the base station spectrum bandwidth corresponding to the satellite base station, and / or, if the number of spectrum bandwidths of satellite base station meets the second condition, the frequency band information includes the terminal spectrum bandwidth corresponding to the terminal device.

[0038] Optionally, in the embodiments of this application, the above-mentioned frequency band information refers to the spectrum bandwidth currently used by the satellite base station or terminal equipment. This frequency band information can be represented by the NR Frequency Band field. Based on the above-mentioned frequency band information, the frequency band information of NR (New Radio Access Technology) can be obtained, such as different frequency bands such as Ka, S, C, and L.

[0039] Optionally, in this embodiment of the application, the first condition for the quantity of spectrum bandwidth refers to the situation where the quantity of spectrum bandwidth configured by the satellite base station is small, or the spectrum bandwidth information is relatively fixed, including but not limited to a single frequency band service scenario or a scenario where the frequency band information is stable. The second condition for the quantity of spectrum bandwidth refers to the situation where the quantity of spectrum bandwidth configured by the satellite base station is large, or the spectrum bandwidth information changes frequently, including but not limited to a scenario where multiple frequency band service scenarios or a scenario where the frequency band information changes frequently, for example, the number of times the frequency band information changes exceeds a preset threshold within a certain period of time.

[0040] For example, the first condition mentioned above refers to the number of spectrum bandwidths of the satellite base station being equal to 1, or the number of spectrum bandwidths of the satellite base station being more than 1 but the frequency band information being relatively fixed and not easily changed over a period of time. That is, the first condition mentioned above corresponds to the configuration attributes of the spectrum bandwidth of the satellite base station to adapt to two different scenarios of spectrum bandwidth configuration of the satellite base station. The second condition mentioned above is the opposite of the first condition. Specifically, if the first condition mentioned above refers to the number of spectrum bandwidths of the satellite base station being equal to 1, then the second condition mentioned above indicates that the number of spectrum bandwidths of the satellite base station is not equal to 1; or, if the first condition mentioned above refers to the number of spectrum bandwidths of the satellite base station being more than 1 but the frequency band information being relatively fixed and not easily changed over a period of time, then the second condition mentioned above indicates that the number of spectrum bandwidths of the satellite base station is more than 1 and the frequency band information changes frequently over a period of time.

[0041] Optionally, in this embodiment, the aforementioned satellite base station may include, but is not limited to, LEO (Low Earth Orbit), MEO (Medium Earth Orbit), and GEO (Geostationary Earth Orbit) satellite communication base stations; the spectrum bandwidth corresponding to the aforementioned satellite base station refers to all frequency band resources that the satellite base station can provide services, which may cover multiple frequency bands such as L, C, S, and Ka, depending on the configuration and service requirements of the satellite communication system; the aforementioned base station spectrum bandwidth refers to the spectrum bandwidth range that the satellite base station reports to the core network when establishing a connection with the core network, which is currently bound to the connection, enabling the core network to identify the frequency band information that the connected terminal device may use, thereby more accurately and efficiently locating and paging the target terminal in paging control.

[0042] For example, frequency band information sent by a satellite base station is received. If the number of spectrum bandwidths of the satellite base station meets the first condition mentioned above, the frequency band information includes the base station spectrum bandwidth corresponding to the satellite base station during the process of establishing a connection between the satellite base station and the core network. If the number of spectrum bandwidths of the satellite base station meets the second condition (equivalent to meeting the second condition mentioned above), the frequency band information includes the terminal spectrum bandwidth corresponding to the terminal device during the process of the terminal device requesting registration in the core network.

[0043] For example, when the spectrum bandwidth configured by the satellite base station meets the first condition mentioned above, during the process of establishing an NG (Next Generation) connection with the core network, the satellite base station will carry NR Frequency Band information (new radio frequency band information) and report the spectrum bandwidth currently supported by the base station. After receiving the NGSetup Request message, the core network will parse and save the correspondence between the current NG connection and the spectrum bandwidth resources, enabling the core network to identify that all terminal devices accessing through this connection use the same spectrum bandwidth. Furthermore, when a paging event occurs, the core network can quickly locate the pre-stored spectrum bandwidth information, calculate the list of base stations and frequency bands that need to be paging, and directly paging these base stations and frequency bands, avoiding unnecessary full-band traversal paging and significantly improving paging efficiency and response speed.

[0044] Optionally, in this embodiment, the aforementioned quantity of spectrum bandwidth not meeting the first condition refers to situations where the number of spectrum bandwidths configured by the satellite base station is large or the spectrum bandwidth information changes frequently, including but not limited to multi-band concurrent service scenarios or environments with high frequency band switching requirements; the aforementioned connection established between the satellite base station and the core network refers to situations where the satellite base station has successfully established a communication link with the core network through the NG interface, and can transmit control plane and user plane data; the aforementioned terminal device refers to user equipment that communicates through the satellite network, including but not limited to mobile phones, IoT devices, vehicle communication terminals, etc.; the aforementioned terminal spectrum bandwidth refers to the frequency band information currently being used by the terminal device, used to determine the paging range and communication service quality of the terminal device.

[0045] Optionally, in this embodiment of the application, the aforementioned base station spectrum bandwidth refers to the frequency band resources that the aforementioned satellite base station can provide services, which may include, but are not limited to, L, C, S, Ka, etc., depending on the configuration of the satellite communication base station; the aforementioned terminal spectrum bandwidth refers to the frequency band actually used by the terminal device when accessing the satellite base station, including but not limited to one of the aforementioned frequency bands, which is specifically determined by the communication needs of the terminal device and the satellite band coverage of its location.

[0046] For example, when the number of spectrum bandwidths corresponding to a satellite base station meets the second condition, multiple frequency bands provide services simultaneously, which cannot be accurately distinguished through connection-level information. Therefore, the standard NG connection established between the satellite base station and the core network will not carry spectrum bandwidth information. When the terminal device sends a registration request message, the satellite base station will determine which frequency band it is using based on the specific cell information (cell information) accessed by the terminal device, that is, determine the aforementioned terminal spectrum bandwidth.

[0047] Furthermore, the satellite base station reports the terminal's spectrum bandwidth information to the core network in the Initial UE Message. The core network receives and stores this information in the user context for subsequent paging. When a paging event occurs, the core network accurately calculates the corresponding frequency band's wavelet information based on the stored terminal spectrum bandwidth, thus initiating a paging request only to the relevant base station and wavelet, avoiding the inefficiency of full-band traversal paging and significantly improving the efficiency and accuracy of paging.

[0048] S204, paging the terminal device to be paging is performed based on frequency band information.

[0049] For example, when the core network needs to page a terminal device (i.e., the aforementioned device to be paged), firstly, the core network determines the frequency band currently used by the terminal device based on the stored terminal user context information, i.e., the terminal spectrum bandwidth; then, in conjunction with the spectrum bandwidth information reported by the satellite base station, i.e., the base station spectrum bandwidth, it calculates the list of base stations and the list of frequency bands to be paged; finally, it sends a paging request to the satellite base station, carrying the precise list of frequency bands, to achieve accurate paging of terminal devices on a specific frequency band.

[0050] In one exemplary embodiment, satellite networks are gradually introducing multi-band support to meet the needs of different service scenarios. Specifically, when a satellite base station simultaneously provides services on multiple frequency bands, the significant differences in coverage and wavelet information between different frequency bands lead to considerable uncertainty in the paging control of the core network. Therefore, using the paging method proposed in this application embodiment can improve paging determinism and stability. Figure 3 This is a schematic diagram of an optional paging method according to an embodiment of this application. The paging process is as follows: Figure 3 As shown:

[0051] Taking the application scenario of low-Earth orbit satellite networks as an example, when a terminal device is not performing any ongoing services and is in CM-IDLE state (call manager idle state), the paging process is triggered when the network side needs to send data or signaling to the terminal device. At this time, the core network calculates all the frequency bands covering the possible locations of the terminal device based on the stored spectrum bandwidth information of the terminal device and the spectrum bandwidth configuration of the low-Earth orbit satellite base station, and sends paging requests only to the base stations corresponding to these frequency bands, avoiding blind searching of other frequency bands and significantly improving the efficiency and accuracy of paging.

[0052] It should be noted that the terminal device in this embodiment can be various types of mobile devices, including but not limited to handheld terminals, vehicle communication devices, IoT sensors, etc.; and the paging device can be one or more of the terminal devices mentioned above, or the paging device can be other terminal devices besides the terminal devices mentioned above, but is a terminal device that is accessing for the first time. The embodiments of this application are also applicable to high-orbit satellite networks, medium-orbit satellite networks, and scenarios of multi-satellite and multi-frequency band hybrid networking, and this application does not limit them.

[0053] In an exemplary embodiment, taking a satellite communication network application scenario as an example, the spectrum bandwidth configuration of the satellite base station affects the paging strategy of the core network. The specific paging operations implemented using the embodiments of this application include, but are not limited to:

[0054] S1-1, when a satellite base station is configured with a single frequency band, such as the Ka band, and the number of such frequency bands meets the first condition (the first condition means that the number of spectrum bandwidths configured by the base station is equal to 1, i.e., only a single frequency band service is provided), during the connection establishment process with the core network, the satellite base station will report the NR Frequency Band field (the field in the above frequency band information) to the core network through the NG Setup Request message in the NGAP (Next Generation Application Protocol) signaling, indicating that the current spectrum bandwidth of the base station is the Ka band. After receiving this message, the core network saves the base station's spectrum bandwidth information and associates it with the connection established with the satellite base station for use when the paging terminal device performs paging operations later.

[0055] S1-2, when a satellite base station is configured with multiple frequency bands simultaneously, such as L, C, S, and Ka bands, and the second condition is met, the core network will not directly obtain the base station's spectrum bandwidth information during the connection establishment process. Instead, when the paging terminal device first accesses the network for registration, the satellite base station will determine and report the frequency band information currently accessed by the paging terminal device, such as the C band, as the terminal's spectrum bandwidth information via the Initial UE Message. After receiving this message, the core network stores the terminal's spectrum bandwidth information in the user context of the paging terminal device for subsequent paging control.

[0056] S2, when the core network needs to page a certain terminal device to be paged, it can calculate the corresponding band list based on the saved base station spectrum bandwidth information or the terminal spectrum bandwidth information stored in the user context of the terminal device to be paged, and send the paging request only to the base station that can receive the specified frequency band.

[0057] It should be noted that if the core network has already saved the base station's spectrum bandwidth information before this paging, paging can be performed according to the base station's spectrum bandwidth; otherwise, the core network will perform paging according to the terminal spectrum bandwidth information of the terminal device to be paging, ensuring that the paging message only covers the frequency band of the target terminal device, thereby improving paging efficiency and accuracy.

[0058] Through the embodiments of this application, frequency band information transmitted by satellite base stations is received. Wherein, if the number of spectrum bandwidths of the satellite base stations meets a first condition, the frequency band information includes the base station spectrum bandwidth corresponding to the satellite base station, and / or, if the number of spectrum bandwidths of the satellite base stations meets a second condition, the frequency band information includes the terminal spectrum bandwidth corresponding to the terminal device. Through dynamic frequency band information management, the goal of improving paging efficiency and accuracy is achieved, thereby realizing the technical effects of optimized spectrum resource utilization and network performance improvement, and thus solving the technical problem of low paging efficiency.

[0059] As an optional approach, the above-mentioned receiving of frequency band information sent by the satellite base station includes: receiving a first request message sent by the satellite base station when the number of spectrum bandwidths corresponding to the satellite base station meets the first condition, wherein the first request message includes the spectrum bandwidth of the base station and is used to instruct the satellite base station to request the establishment of a connection; saving a first mapping relationship between the spectrum bandwidth of the base station and the satellite base station based on the first request message, wherein the first mapping relationship is used to page the paging terminal device associated with the satellite base station; and returning a first response message to the satellite base station, wherein the first response message is used to indicate permission to establish a connection with the satellite base station.

[0060] Optionally, in this embodiment, the first request message refers to the NG Setup Request message sent by the satellite base station to the core network to request the establishment of a connection with the core network. This message includes NR FrequencyBand information to indicate the spectrum bandwidth currently supported by the base station. The base station spectrum bandwidth is used to identify the service frequency band of the base station. The first mapping relationship refers to the correspondence between NG connections and spectrum bandwidth resources stored by the core network, used for quickly locating and identifying the frequency band of the terminal device on the connection in subsequent paging control. The first response message refers to the NG Setup Response message (5G establishment response) returned by the core network to the satellite base station to confirm the connection establishment request and indicate successful connection establishment.

[0061] For example, in the initial stage of establishing a connection with the core network, the aforementioned satellite base station carries NR Frequency Band information in the NG Setup Request message, indicating the frequency band it currently serves. After receiving the first request message, the core network parses and saves the first mapping relationship between the base station's spectrum bandwidth and the satellite base station, so that it can quickly identify the frequency band information based on the connection in subsequent paging control. Subsequently, the core network returns a first response message to the satellite base station, confirming permission to establish a connection with the satellite base station, thus completing the connection establishment process.

[0062] In one exemplary embodiment, Figure 4 This is a schematic diagram of a node connection-level control scenario for an optional paging method according to an embodiment of this application, as shown below. Figure 4 As shown, it includes:

[0063] Step S1: When the satellite base station initiates the establishment of an NG connection, it reports the NR Frequency Band information in the NG SetupRequest message (first request message) according to the spectrum bandwidth configuration information.

[0064] Step S2: The core network parses the NG connection establishment request, determines and stores the correspondence between the current NG connection and the spectrum bandwidth (first mapping relationship);

[0065] Step S3: When the core network receives a terminal registration request from the current NG connection, it stores the saved spectrum bandwidth information into the user context.

[0066] Step S4: When paging occurs, the core network calculates the list of base stations to be paging and the corresponding bandgap list based on the spectrum bandwidth information stored in the context of the paging terminal, and initiates a paging request for the paging base station list, carrying the bandgap list information.

[0067] In another exemplary embodiment, taking a single-band service scenario in a Low Earth Orbit (LEO) satellite network as an example, when an LEO satellite base station establishes a connection with the core network, the satellite base station reports its currently supported frequency bands (such as the Ka band) as its base station spectrum bandwidth via a first request message (NG Setup Request). Upon receiving the request, the core network establishes a first mapping relationship based on the NRF frequency band information, binding the base station spectrum bandwidth to the satellite base station's NG connection. This ensures that paging control for all terminal devices using this connection can be optimized based on this frequency band. After the core network completes saving the mapping relationship, it sends a first response message (NG Setup Response) to the satellite base station, indicating successful connection establishment, and then begins providing services and executing the optimized paging control process.

[0068] It should be noted that, Figure 5 This is a schematic diagram of a transparent forwarding mode for an optional paging method according to an embodiment of this application. Figure 6 This is a schematic diagram of an on-board regeneration mode of an optional paging method according to an embodiment of this application; the satellite base station in this embodiment can be applied to different satellite orbits, such as high-Earth orbit, medium-Earth orbit, low-Earth orbit, etc., and under different network architectures, such as... Figure 5 The transparent forwarding mode shown or as Figure 6The on-board regeneration mode is shown; meanwhile, the establishment and maintenance of the first mapping relationship can employ various technical means, including but not limited to database storage, memory-mapped tables, etc., to adapt to different network scales and needs. This application does not limit this.

[0069] Through the embodiments of this application, a core network paging control optimization scheme based on spectrum bandwidth and connection mapping is adopted, which achieves the technical effect of accurate paging control of terminal devices in a single-frequency band service scenario of satellite network, thereby reducing paging resource consumption, improving paging efficiency and network service quality.

[0070] As an optional solution, receiving the first request message sent by the satellite base station when the number of spectrum bandwidths corresponding to the satellite base station meets the first condition includes: receiving the first request message sent by the satellite base station when the number of spectrum bandwidths corresponding to the satellite base station meets the first condition, wherein the first request message includes a first field, the first field being used to indicate the spectrum bandwidth of the base station; and saving the first mapping relationship between the spectrum bandwidth of the base station and the satellite base station based on the first request message includes: in response to detecting the first field in the first request message, saving the first mapping relationship based on the first field.

[0071] Optionally, in the embodiments of this application, the first field mentioned above refers to NR Frequency Band, which is used to indicate the spectrum bandwidth currently supported by the satellite base station.

[0072] For example, when the first condition is met, that is, the spectrum bandwidth configured by the satellite base station is small or relatively fixed, the satellite base station carries a first field (NRFrequency Band) indicating the current spectrum bandwidth when sending the first request message (NG Setup Request); after receiving the first request message, the core network parses the first field therein and saves the first mapping relationship between the base station spectrum bandwidth and the satellite base station to ensure that subsequent paging control can be optimized based on frequency band information.

[0073] In an exemplary embodiment, taking a single-band service scenario in a low-Earth orbit (LEO) satellite network as an example, when an LEO satellite base station is configured to use only the Ka band for service, during the process of establishing a connection with the core network, it reports the first field (NR Frequency Band) through a first request message (NG Setup Request), indicating that the current spectrum bandwidth is the Ka band. After receiving the first request message and parsing the first field, the core network saves the first mapping relationship between the base station spectrum bandwidth (Ka band) and the satellite base station. Thus, when performing paging control in the future, it can directly calculate the list of base stations and frequency bands to be paging based on the mapping relationship, thereby achieving accurate paging.

[0074] It should be noted that the carrying and parsing of the first field (NR Frequency Band) can be implemented using the control logic of a software-defined network or processed by a hardware accelerator to meet the performance requirements of different network environments; the connection between the satellite base station and the core network can be a fixed ground link or a dynamic link established through other satellites or relay stations, and this application embodiment does not limit this.

[0075] Through the embodiments of this application, by adopting a first request message based on spectrum bandwidth indication and a first mapping relationship storage mechanism, the core network achieves efficient and accurate paging control technology for terminal devices in a single-band satellite network service scenario. This reduces resource consumption during the paging process, improves paging efficiency and network service quality, and also provides a flexible and effective reference framework for paging control in multi-band service scenarios.

[0076] As an optional solution, receiving the frequency band information sent by the satellite base station includes: receiving a registration request message sent by the terminal device through the satellite base station; saving a second mapping relationship between the terminal's spectrum bandwidth and the terminal device based on the registration request message, wherein the second mapping relationship is used to page the terminal device to be paged corresponding to the terminal's spectrum bandwidth; and returning a registration response message to the satellite base station, wherein the registration response message is used to indicate whether the terminal device is allowed to register.

[0077] Optionally, in this embodiment, the registration request message refers to the Initial UE Message, which the terminal device sends to the core network to request registration when accessing the satellite network; the second mapping relationship refers to the mapping between the spectrum bandwidth stored in the core network and the terminal device, which is used for accurate positioning and addressing in subsequent paging control; the registration response message refers to the Initial Context Setup Response message, which the core network confirms the registration request of the terminal device and allows the terminal device to register through the registration response message.

[0078] For example, when the spectrum bandwidth configured by the aforementioned satellite base station meets the second condition, the standard connection (NG Setup, next-generation network procedure) established between the base station and the core network will not carry specific frequency band information, because the frequency band information may change frequently or multiple frequency bands may provide services simultaneously, making it impossible to accurately distinguish them through connection-level information. When the terminal device registers for network access, the satellite base station reports the terminal spectrum bandwidth information to the core network through the aforementioned registration request message (Initial UE Message). After receiving the registration request, the core network saves the second mapping relationship between the terminal spectrum bandwidth and the terminal device for quickly identifying the frequency band information of the terminal device during subsequent paging control. Finally, the core network returns a registration response message to the satellite base station, confirming the registration of the terminal device and allowing it to access the network.

[0079] In one exemplary embodiment, Figure 7 This is a user-level control scenario diagram of an optional paging method according to an embodiment of this application, such as... Figure 7 As shown, it includes:

[0080] Step S1: The satellite base station establishes a standard NG connection with the core network;

[0081] In step S2, the satellite base station receives the terminal registration request, obtains the spectrum bandwidth information used based on the cell information accessed by the terminal, and reports the NR Frequency Band information to the core network in the Initial UE Message.

[0082] Step S3: The core network saves the spectrum bandwidth information to the user context;

[0083] Step S4: When paging occurs, the core network calculates the list of base stations to be paging and the corresponding bandgap list based on the spectrum bandwidth information stored in the context of the paging terminal, and initiates a paging request for the paging base station list, carrying the bandgap list information.

[0084] In another exemplary embodiment, taking a multi-band concurrent service scenario in a Low Earth Orbit (LEO) satellite network as an example, an LEO satellite base station simultaneously supports multiple frequency bands such as L, C, S, and Ka. However, due to the abundance of frequency band resources and their complex usage, frequency band information cannot be directly reported when an NG connection is established. When a terminal device attempts to register with the network, the specific frequency band it accesses is reported to the core network by the base station via a registration request message. The core network receives and parses the registration request message, stores it as the terminal's spectrum bandwidth in the terminal device's context, and establishes a second mapping relationship with the terminal device. Subsequently, the core network sends a registration response message to the satellite base station, confirming the terminal device's registration and allowing it to use the specified frequency band for communication. When there is a paging request, the core network can directly obtain the terminal device's spectrum bandwidth information from the second mapping relationship, thereby accurately paging the terminal.

[0085] It should be noted that the connection establishment process between the aforementioned satellite base station and the core network (the interaction between the second request message and the second response message) can employ various communication protocols and standards, including but not limited to 3GPP definitions; when sending the registration request message, the aforementioned terminal equipment can use different access technologies, such as... Figure 5 Transparent forwarding as shown or as Figure 6 The on-board regeneration mode shown; the second mapping relationship stored in the core network can adopt various data structures and storage mechanisms, such as databases, memory-mapped tables, etc., to adapt to different network sizes and complexities. This application does not limit this aspect in its embodiments.

[0086] Through the embodiments of this application, a mechanism based on the reporting of spectrum bandwidth information when the paging terminal device registers and a strategy for saving the second mapping relationship between the terminal spectrum bandwidth and the paging terminal device are adopted. This achieves efficient and accurate paging control technology for the paging terminal device in the scenario of concurrent service in multiple frequency bands of satellite network, thereby optimizing network resource utilization, improving paging efficiency and ensuring user service quality.

[0087] As an optional solution, receiving the registration request message sent by the terminal device through the satellite base station includes: receiving the registration request message sent by the terminal device through the satellite base station, wherein the registration request message includes a second field, the second field being used to indicate the terminal's spectrum bandwidth; and saving a second mapping relationship between the terminal's spectrum bandwidth and the terminal device based on the registration request message, including: in response to detecting the second field in the registration request message, saving the second mapping relationship between the terminal's spectrum bandwidth and the terminal device.

[0088] Optionally, in this embodiment of the application, the second field mentioned above refers to NR Frequency Band, which is an indicator field in the registration request message used to report the spectrum bandwidth information currently accessed by the terminal device.

[0089] For example, when the aforementioned terminal device accesses the aforementioned satellite base station, it sends a registration request message (Initial UEMessage). This message contains a second field (NR Frequency Band) to indicate the spectrum bandwidth it is currently accessing. After receiving the registration request message, the core network detects and parses the second field to obtain the terminal spectrum bandwidth information of the terminal device. Subsequently, it saves the second mapping relationship between the terminal spectrum bandwidth and the terminal device for subsequent paging control, ensuring that paging can accurately reach the service range of the frequency band where the terminal device is located.

[0090] In an exemplary embodiment, taking a multi-band service scenario of a high-orbit (GEO) satellite network as an example, when a terminal device attempts to access the GEO satellite network, it sends an Initial UE Message containing a second field (NR Frequency Band), indicating that it is currently using the C band. Upon receiving this message and detecting the second field, the core network saves the second mapping relationship between the C band and the terminal device. When paging the terminal device is required, the core network can quickly locate the C band from the saved mapping relationship, thereby sending a paging request to base stations within the C band coverage area. This avoids full-band traversal paging, improving paging efficiency and network service quality.

[0091] It should be noted that the reporting of spectrum bandwidth information of the aforementioned terminal devices can be achieved through various technical means, including but not limited to adding fields to the registration request message or utilizing the extended functions of existing fields. This application embodiment does not limit this.

[0092] Through the embodiments of this application, by adopting the mechanism of reporting spectrum bandwidth information during terminal registration and the strategy of saving the second mapping relationship between terminal spectrum bandwidth and terminal device, the technical effect of precise paging control of terminal device in multi-band satellite network environment is achieved, thereby reducing paging resource consumption, improving paging efficiency and ensuring user experience quality.

[0093] As an optional approach, receiving the frequency band information transmitted by the satellite base station includes: receiving the base station spectrum bandwidth transmitted by the satellite base station when the number of spectrum bandwidths corresponding to the satellite base station is unique; and receiving the terminal spectrum bandwidth transmitted by the satellite base station when the number of spectrum bandwidths corresponding to the satellite base station is not unique.

[0094] Optionally, in the embodiments of this application, the number of spectrum bandwidths mentioned above is unique, which means that the satellite base station is configured with one and only one type of spectrum bandwidth resource for service, including but not limited to a specific frequency band such as the Ka band, for providing satellite communication services; the number of spectrum bandwidths mentioned above is not unique, which means that the satellite base station is configured with multiple spectrum bandwidth resources for service, including but not limited to simultaneously supporting multiple frequency bands such as L, C, S, and Ka, to meet different communication needs or environments.

[0095] For example, if the number of spectrum bandwidths corresponding to the aforementioned satellite base station is unique, the base station spectrum bandwidth sent by the aforementioned satellite base station is received; if the number of spectrum bandwidths corresponding to the aforementioned satellite base station is not unique, the aforementioned satellite base station has established a connection with the core network, and the aforementioned satellite base station has received the aforementioned registration request message, the terminal spectrum bandwidth sent by the aforementioned satellite base station is received.

[0096] For example, when the spectrum bandwidth resource corresponding to the satellite base station is unique, the core network directly receives the base station spectrum bandwidth information sent by the satellite base station; however, when the spectrum bandwidth resource is not unique, in the scenario where the satellite base station and the core network have established a standard connection, the core network does not directly obtain the frequency band information from the connection, but waits to receive the registration request message (Initial UE Message) sent by the terminal device through the satellite base station, which contains the terminal spectrum bandwidth information, and then saves and processes the information to achieve precise paging control.

[0097] Through the embodiments of this application, an optimized paging control mechanism based on spectrum bandwidth information reporting and storage is adopted, which achieves efficient and accurate paging control of terminal devices in both single-band and multi-band satellite network service scenarios, thereby improving paging efficiency, optimizing network resource utilization, and enhancing user experience quality.

[0098] As an optional approach, the above-mentioned paging of the terminal device to be paging based on the base station spectrum bandwidth and the terminal spectrum bandwidth includes: determining a mapping relationship set based on the frequency band information, wherein the mapping relationship set includes the mapping relationship between the satellite base station and the base station spectrum bandwidth that satisfies the first condition and the mapping relationship between the terminal device associated with the satellite base station and the terminal spectrum bandwidth that satisfies the second condition; and paging the terminal device to be paging based on the mapping relationship set.

[0099] Optionally, in the embodiments of this application, the aforementioned mapping relationship set refers to a dataset established within the core network for storing and managing the mapping relationship between base station spectrum bandwidth and terminal spectrum bandwidth and associated satellite base stations or terminal devices.

[0100] For example, after receiving the spectrum bandwidth information from the aforementioned satellite base stations, the core network can determine how to establish a mapping relationship set based on whether the spectrum bandwidth of the aforementioned base stations is unique and whether it meets the first condition or the second condition. Specifically:

[0101] For a single-frequency band base station, the core network directly stores the mapping relationship between the base station's spectrum bandwidth and the satellite base station; while for a multi-frequency band service base station, the core network constructs a mapping relationship between the terminal device and the terminal spectrum bandwidth based on the terminal spectrum bandwidth information reported when the terminal device registers. Subsequently, the core network executes paging control for the terminal device based on this mapping relationship set.

[0102] It should be noted that the establishment and maintenance of the above mapping relationship set can be implemented using various data structures and algorithms, such as hash tables, tree structures, or database records, to adapt to different network environments and needs. The judgment of the first and second conditions mentioned above may vary depending on the network operator's strategy, the characteristics of the satellite network, and the complexity of the frequency band configuration. For example, it may be set based on the number of frequency bands, the frequency used, or the frequency that changes. This application does not limit this. The update mechanism of the above mapping relationship set can be real-time or based on an event-triggered or periodic update strategy.

[0103] Through the embodiments of this application, a dynamic mapping relationship set construction and maintenance mechanism based on spectrum bandwidth information is adopted to achieve the effect of precise paging control technology for satellite base stations and terminal equipment under different frequency band services, thereby improving paging efficiency, reducing network resource consumption, and enhancing user service quality.

[0104] As an optional approach, the paging of the terminal device to be paging based on the aforementioned mapping relationship set includes: obtaining the target satellite base station associated with the terminal device to be paging; searching for the base station spectrum bandwidth corresponding to the target satellite base station in the aforementioned mapping relationship set; if the base station spectrum bandwidth is found, paging is performed based on the base station spectrum bandwidth; if the base station spectrum bandwidth is not found, the terminal spectrum bandwidth is found, and paging is performed based on the terminal spectrum bandwidth.

[0105] Optionally, in this embodiment of the application, the satellite base station associated with the terminal device to be paged refers to the satellite base station currently connected to the terminal device that needs to receive the paging message, including but not limited to low Earth orbit (LEO), medium Earth orbit (MEO), or high Earth orbit (GEO) satellite base stations.

[0106] For example, when the core network needs to page the aforementioned terminal device, it first obtains the satellite base station information associated with the terminal device, and then searches for the base station spectrum bandwidth corresponding to the satellite base station in the mapping relationship set. If the base station spectrum bandwidth is found, the core network will directly perform paging control based on this spectrum bandwidth information; if the base station spectrum bandwidth is not found, the core network will search for the terminal spectrum bandwidth information associated with the terminal device and perform paging operation based on this information to ensure that the paging request is only sent to the satellite base station that can receive the frequency band of the target terminal device.

[0107] In an exemplary embodiment, taking the multi-band service scenario of the LEO satellite network as an example, assume that the terminal device A to be paging is currently connected to satellite base station B, and base station B simultaneously supports L, C, S, and Ka band services. When the core network receives a paging request, it first obtains the satellite base station B information associated with terminal device A. According to the stored mapping relationship set, the core network finds that the spectrum bandwidth information corresponding to base station B is Ka band. Therefore, it performs paging control according to Ka band, sending paging requests only to base stations within the Ka band coverage area. Conversely, if the core network's mapping relationship set does not directly store the spectrum bandwidth information of base station B, the core network will look up the terminal spectrum bandwidth information of terminal device A, assuming it is C band. The core network will perform paging control according to C band information, sending paging requests only to base stations within the C band coverage area, ensuring accurate and efficient paging operations.

[0108] It should be noted that the core network obtains the satellite base station information associated with the terminal device to be paged in the above-mentioned manner, which may be achieved in various ways, including but not limited to the UE context information in NGAP signaling; the above-mentioned paging operation may involve multiple components and protocols in the network, including base stations, core network, paging policy server, etc., which are not limited in this application.

[0109] Through the embodiments of this application, a spectrum bandwidth information lookup and application mechanism based on a mapping relationship set is adopted to achieve the technical effects of rapid positioning and efficient paging control of the terminal device to be paging in the satellite network, thereby reducing resource waste during the paging process, improving network response speed, and enhancing the user's communication experience.

[0110] As an optional approach, the above-mentioned paging of the terminal device to be paging based on the above-mentioned mapping relationship set includes: determining a band position list based on the above-mentioned mapping relationship set, wherein the above-mentioned band position list corresponds to the above-mentioned frequency band information in the above-mentioned mapping relationship set; and initiating a paging request to the terminal device to be paging according to the above-mentioned band position list.

[0111] Optionally, in the embodiments of this application, the above-mentioned wave position list refers to a list containing the physical beam positions or numbers covered by satellite base stations corresponding to each spectrum bandwidth, used to indicate under which wave positions or under which paging requests are initiated to the target terminal device.

[0112] For example, on the core network side of a satellite network, when it is necessary to page a terminal device, the core network first accesses the mapping relationship set to find the spectrum bandwidth information corresponding to the terminal device, which may be the base station spectrum bandwidth or the terminal spectrum bandwidth. Based on the base station spectrum bandwidth or the terminal spectrum bandwidth, the core network further calculates or queries the band list. The band list contains the satellite beam positions or numbers that can cover the target terminal device. Then, according to the position or number in the band list, the core network sends a paging request to the base station in the relevant band coverage area to ensure that the paging message is only sent to the satellite base station that can receive messages in that specific frequency band.

[0113] Through the embodiments of this application, a wavelet list calculation and application mechanism based on spectrum bandwidth information is adopted to achieve accurate positioning and efficient paging control of the terminal device to be paging in the satellite network, improve the accuracy and response speed of the paging process, and achieve the purpose of optimizing network resource utilization, reducing system overhead and improving user communication experience.

[0114] Optionally, as an alternative implementation, another paging method includes: when the number of spectrum bandwidths configured by the satellite base station is a first number, receiving a first request message sent by the satellite base station, wherein the first request message includes base station spectrum bandwidth information of the satellite base station, the base station spectrum bandwidth information being used to indicate the spectrum bandwidth corresponding to the satellite base station; when the number of spectrum bandwidths configured by the satellite base station is a second number, the satellite base station has established a connection with the core network, and the satellite base station has received a registration request message sent by the terminal device, receiving a second request message sent by the satellite base station, wherein the second request message includes terminal spectrum bandwidth information sent by the terminal device based on the registration request message, the terminal spectrum bandwidth information being used to indicate the spectrum bandwidth corresponding to the terminal device, the second number being greater than the first number; and paging the terminal device to be paging based on the first request message and the second request message.

[0115] In an exemplary embodiment, taking the multi-band parallel service scenario of a low-Earth orbit (LEO) satellite network as an example, the satellite base station is configured to provide services for four frequency bands, namely L, C, S, and Ka, at the same time. In this case, the second quantity (multi-band) is greater than the first quantity (single-band).

[0116] S1: When the LEO satellite base station is configured with only a single frequency band, assuming it is the Ka band, the base station will send an NG Setup Request message (i.e., the first request message) during the connection establishment process with the core network. This message contains the base station's spectrum bandwidth information (NR Frequency Band field), indicating that its current service frequency band is the Ka band. After receiving this message, the core network stores the mapping relationship between the base station's spectrum bandwidth information and the satellite base station for subsequent paging control.

[0117] S2: When the LEO satellite base station is configured to serve four frequency bands (L, C, S, and Ka), when the terminal device accesses the network for the first time, the satellite base station receives the Initial UE Message (registration request message) sent by the terminal device. The satellite base station will then report the NR Frequency Band field in the second request message (which may be an Initial Context Setup Request or other appropriate message) to indicate the frequency band currently accessed by the terminal device, such as the C band. After receiving this message, the core network saves the mapping relationship between the terminal's spectrum bandwidth information and the terminal device to prepare for accurate paging control.

[0118] S3: When the core network needs to page a terminal device, it calculates the correct bandgap list based on the spectrum bandwidth information stored in the first and second request messages, combined with the mapping relationship set. Then, it sends paging requests only to base stations in the corresponding frequency band coverage area, achieving accurate paging. In scenario S1, the core network directly uses the base station spectrum bandwidth information for paging; in scenario S2, the core network uses the terminal spectrum bandwidth information for paging, ensuring that paging messages are only sent to base stations capable of receiving messages in that specific frequency band.

[0119] It should be noted that the implementation of the first and second request messages may be accomplished through different 3GPP signaling procedures, depending on the satellite network architecture and the operator's network configuration. The construction and maintenance of the mapping relationship set can be varied, such as using memory-mapped tables, database records, or other data structures; the specific implementation should be flexibly selected based on network scale and requirements. Furthermore, the registration and paging procedures for the aforementioned terminal devices may vary depending on different network standards and protocols, and this application embodiment does not limit this.

[0120] Through the embodiments of this application, a first request message and a second request message mechanism based on spectrum bandwidth information are adopted to achieve the technical effects of accurate positioning and efficient paging control of terminal devices in satellite network environments of different frequency bands, thereby reducing resource consumption during the paging process, improving network response speed, and ensuring user experience quality.

[0121] Optionally, as an alternative implementation, another paging method includes: determining the spectrum bandwidth of the satellite base station during the process of establishing a connection between the satellite base station and the core network, provided that the quantity of spectrum bandwidth of the satellite base station meets a first condition; determining the spectrum bandwidth of the terminal device during the process of the terminal device requesting registration in the core network, provided that the quantity of spectrum bandwidth of the satellite base station meets the second condition; and paging the terminal device to be paging based on the spectrum bandwidth of the satellite base station or the spectrum bandwidth of the terminal device.

[0122] In an exemplary embodiment, taking a low-Earth orbit (LEO) satellite network application scenario as an example, assume that the satellite base station is configured with a single frequency band (Ka), satisfying a first condition (the first condition may be that the number of satellite base station spectrum bandwidths is equal to 1, i.e., only a single frequency band service is configured). During the connection establishment process between the base station and the core network, the satellite base station reports the NR Frequency Band field in the NG Setup Request message, indicating that its spectrum bandwidth is the Ka band. After receiving this message, the core network records the base station spectrum bandwidth information and establishes a connection with the satellite base station. When it is necessary to paging a specific terminal device, the core network calculates a band position list based on the saved base station spectrum bandwidth information (i.e., the Ka band), and then sends paging requests only to the base stations corresponding to the satellite beams covered by the Ka band, achieving precise paging.

[0123] In another scenario, the satellite base station is configured with four frequency bands simultaneously: L, C, S, and Ka, satisfying the second condition (the second condition is that the number of satellite base station spectrum bandwidths is greater than one, i.e., multi-band service is configured and changes frequently). In this case, the core network does not directly determine the base station's spectrum bandwidth during connection establishment. Instead, during the terminal device's registration process with the core network (i.e., when receiving the Initial UE Message), the satellite base station reports the NR Frequency Band field in the message, indicating the frequency band currently used by the terminal device, such as the C band. The core network associates this terminal spectrum bandwidth information with the terminal device and stores it in a mapping set. When paging this terminal device is required, the core network determines the band list based on the stored terminal spectrum bandwidth information (i.e., the C band) and sends paging requests only to the base stations corresponding to the satellite beams covered by the C band, thus achieving accurate paging.

[0124] Through the embodiments of this application, a flexible paging control strategy based on spectrum bandwidth information is adopted, which realizes the technical effect of determining the paging range according to the actual frequency band usage of satellite base stations or terminal equipment, thereby achieving the purpose of improving paging efficiency, reducing network resource waste, and improving user service quality.

[0125] In an exemplary embodiment, the paging method proposed in this application can be applied to the field of satellite communication. Specifically, in mobile communication scenarios, when the terminal is not performing any service, it enters the CM-IDLE state (idle state). When the network side needs to send data or signaling to the UE (terminal device), the paging process is triggered. When the UE is in the CM-CONNECT state (connection management connection state), it can also activate certain specified PDU sessions (Protocol Data Units) through the paging process to establish a user plane connection for data transmission. The UE's paging process is as follows: Figure 3 As shown; based on the high dynamic characteristics of satellites, satellite paging schemes will be optimized and enhanced. Taking the satellite's on-board regeneration mode as an example, a paging optimization scheme based on wave positions is generally adopted. A typical approach is to optimize paging based on the terminal location. Taking the last reported location of the terminal in the idle state as the center, a Delta (distance threshold) is set, and a range is defined for the terminal with Delta as the radius. Targeted and precise paging is performed on the wave positions involved within the range.

[0126] Furthermore, to differentiate between LEO, MEO, and GEO, 3GPP (3rd Generation Partnership Project, the international standards organization) added a RAT Information field (providing information about Radio Access Technology) to the NG Setup Request message. This field distinguishes satellite base station access for different orbital plane types. In actual satellite networking scenarios, even within the same orbital plane, such as LEO, user links may utilize multiple frequency bands, such as L, C, S, and Ka bands. The base stations handling different frequency bands may operate independently or be fully reused. Because the coverage areas of different frequency bands vary, the paging range also differs. Since 3GPP has not currently considered this situation, the core network may lack necessary information during processing and be unsure how to paging the base station.

[0127] For example, taking the on-board regeneration scenario with wavelet-based paging optimization as an example, the wavelet information for different frequency bands is different, and the core network needs to perform targeted calculations based on the frequency band currently accessed and used by the terminal. If different frequency bands use independent base station boards to access the core network, the core network can determine the different frequency bands currently served by different base stations based on the IP (network address) configuration of the NG link (Next Generation link), but this method poses challenges for future maintenance. If different frequency bands use a converged base station board to access the core network, the core network cannot identify them through the NG connection, and a new mechanism needs to be introduced. One solution is to configure the frequency band information corresponding to all wavelet information, but this requires large storage, is complex to maintain, and has low query efficiency.

[0128] To address the above issues, embodiments of this application can implement a paging control optimization scheme based on spectrum bandwidth at both the node connection level and the end-user level. Specifically:

[0129] S1, Node Connection Level Control Scenario: When a satellite base station is configured with a unique spectrum bandwidth service, when establishing an NG connection between the base station and the core network, the base station carries an NR Frequency Band indication and reports the spectrum bandwidth information currently supported by the core network. The core network saves the correspondence between the current NG connection and the spectrum bandwidth resources. Subsequently, all terminals coming from the current NG connection are considered to be accessing using this spectrum bandwidth. During paging, the core network searches and paging is performed from the wavelet information corresponding to this spectrum bandwidth. Figure 4 As shown:

[0130] S1-2, When the base station initiates NG connection establishment, it reports NRF frequencyBand information in the NGSetupRequest message according to the spectrum bandwidth configuration information;

[0131] Step 1.3: The core network parses the NG connection establishment request, determines and stores the correspondence between the current NG connection and the spectrum bandwidth;

[0132] Step 2.3: When the core network receives a terminal registration request from the current NG connection, it stores the saved spectrum bandwidth information into the user context.

[0133] Step 3.1: When paging occurs, the core network calculates the list of base stations to be paging and the corresponding bandgap list based on the spectrum bandwidth information stored in the context of the paging terminal, and initiates a paging request for the paging base station list, carrying the bandgap list information.

[0134] S2, User-level Control Scenario: When a satellite base station simultaneously provides multiple spectrum bandwidth services, the NG connection establishment process cannot distinguish the spectrum bandwidth services provided by different cells / wavelengths. Therefore, the NG connection establishment process does not need to carry the NR FrequencyBand message. When a terminal user accesses the satellite base station, the base station determines which frequency band the user is currently using and reports the current spectrum bandwidth information of the core network in the Initial UE Message via the NR Frequency Band indication. When paging this terminal user, the system will search and paging from the wavelength information corresponding to that spectrum bandwidth, such as... Figure 7 As shown:

[0135] Step 1.2 The base station establishes a standard NG connection with the core network;

[0136] Step 2.2 When the base station receives the terminal registration request, it obtains the spectrum bandwidth information used by the terminal based on the cell information accessed by the terminal. The base station reports the NR Frequency Band information to the core network in the Initial UE Message.

[0137] Step 2.3 The core network saves the spectrum bandwidth information to the user context;

[0138] Step 3.1 When paging occurs, the core network calculates the list of base stations to be paging and the corresponding bandgap list based on the spectrum bandwidth information stored in the context of the paging terminal, and initiates a paging request for the paging base station list, carrying the bandgap list information.

[0139] It should be noted that the node connection-level control scenario and the user-level control scenario can be deployed separately or in combination. Priority should be given to the node connection-level control scenario, followed by the user-level control scenario.

[0140] Furthermore, based on the paging method proposed in this application, optimizations to the 3GPP standard protocol may include, but are not limited to:

[0141] The NG Setup Request and Initial UE Message messages are as follows:

[0142] S1, modify NG Setup Request, add the NR Frequency Band field, type integer, valid value 1~1024. For NTN scenarios (Non-Terrestrial Network), if the satellite base station serves a single spectrum bandwidth, this IE (Information Element, a field used to carry specific information) needs to be included:

[0143] Table 1

[0144]

[0145] S2, modify the INITIAL UE MESSAGE, add an NR Frequency Band field, type integer, valid value 1~1024. For NTN scenarios, if the NG Setup Request cannot distinguish the NR Frequency Band, then when the satellite terminal registers, the satellite base station needs to determine and report the spectrum bandwidth information currently accessed by the terminal in the core network.

[0146] Table 2

[0147]

[0148]

[0149] This application provides an enhanced core network paging control method, process, and protocol format for differentiating different spectrum bandwidths. Under the condition that the base station is configured with a single spectrum bandwidth, the base station reports the NR Frequency Band to the core network during the NG connection establishment process. Under the condition that multiple frequency bands reuse the same base station, the base station determines and reports the NR Frequency Band to the core network during the terminal registration process. Furthermore, in both scenarios, the core network can store the NR Frequency Band in the terminal user context. When paging occurs, the core network calculates the paging base station and frequency band list based on the NR Frequency Band stored in the terminal user context and frequency band planning. Compared to the core network distinguishing the frequency band information of the current frequency band through configuration, this method requires less stored information, is simpler to maintain, and has higher query efficiency.

[0152] According to another aspect of the embodiments of this application, a paging device for implementing the above-described paging method is also provided. For example... Figure 8 As shown, the device includes:

[0153] The receiving module 802 is used to receive frequency band information transmitted by the satellite base station, wherein, when the number of spectrum bandwidths of the satellite base station meets a first condition, the frequency band information includes the base station spectrum bandwidth corresponding to the satellite base station, and / or, when the number of spectrum bandwidths of the satellite base station meets a second condition, the frequency band information includes the terminal spectrum bandwidth corresponding to the terminal device.
