[0057] The core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), etc. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited. If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0058] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices jointly, and the embodiments of the present application do not make a specific limitation in this regard. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0059] For the convenience of understanding the embodiments of the present application, a non-terrestrial network (NTN) related to the present application is described.

[0060] The non-terrestrial network refers to a network or network segment using a satellite (Satellite) or unmanned aerial system (Unmanned Aircraft System, UAS) platform for transmission. Compared with a ground communication system, a satellite-based non-terrestrial communication system has a more extensive coverage range, and typical scenarios include continuous coverage in remote mountainous areas, deserts, oceans, forests, or emergency communication when a ground base station is damaged due to natural disasters.

[0061] In the embodiments of the present application, the satellite includes but is not limited to a low earth orbiting (Low Earth Orbiting, LEO) satellite, a medium earth orbiting (Medium Earth Orbiting, MEO) satellite, a geostationary earth orbiting (Geostationary Earth Orbiting, GEO) satellite, and a highly elliptical orbiting (Highly Elliptical Orbiting, HEO) satellite.

[0062] FIG. 2 shows a typical NTN deployment scenario, in which the link between the UE and the satellite is called a service link (Service link), and the link between the satellite and the ground gateway is called a feeder link (Feeder link). In some scenarios (such as low earth orbiting satellites LEO), due to the movement of the satellite, switching of the Service link and / or the Feeder link occurs. For Service link switching, the serving satellite of all UEs in the cell needs to be switched from one satellite to another satellite. For Feeder link switching, a certain satellite needs to be switched from one ground gateway to another ground gateway.

[0063] The NTN communication system includes a transparent payload-based NTN communication system and a regenerative payload-based NTN communication system. For the transparent payload-based NTN communication system, the terminal, the base station, and the core network device are all deployed on the ground, and the communication data between the terminal and the network device is transferred via the satellite in the air. In the transparent payload-based NTN communication system, the satellite only forwards the data between the base station and the terminal, and does not decode and process the data. For the regenerative payload-based NTN communication system, the satellite has part or all of the base station function, and can decode and process the uplink or downlink data.

[0064] For the convenience of understanding the embodiments of the present application, the paging process related to the present application is described.

[0065] As shown in FIG. 3, step 1: when there is downlink data or signaling to be sent to a radio resource control (RRC) idle state terminal, the AMF first pages the terminal through the paging process, and the AMF sends the paging to the RAN node covered by the registration area (RA) of the terminal.

[0066] Step 2: After the RAN node receives the paging, the RAN node needs to perform paging on the terminal located in the tracking area identity (TAI) list for paging. For each cell belonging to the tracking area (TA) indicated in the TAI list for paging, the RAN node generates a paging message on the air interface.

[0067] For the core-initiated paging process, such as when the terminal is in the RRC idle state, the terminal will respond to the paging after receiving the paging, triggering the non-access layer (NAS) connection establishment (corresponding to the RRC connection establishment), and the NAS connection establishment is generally a service request process or a registration update (TAU) process.

[0068] If the terminal is in the RRC inactive state, the paging is initiated by the RAN node, which is called RAN paging, and the base station sends the RAN notification / paging message to the terminal, and the terminal responds to the notification / paging to perform the RRC resume process, etc.

[0069] For the convenience of understanding the embodiments of the present application, the paging alert notification related to the present application is described.

[0070] The communication between the satellite and the smart phone usually has very limited power margin, and usually needs line-of-sight (LOS) to obtain the best performance. For the call initiated by the mobile terminal, the terminal can perceive the channel quality, and realize the LOS communication by consciously adjusting the signal transmission / reception point. However, for the downlink communication of the mobile terminal, the terminal does not know its channel condition, and may miss important calls / messages due to poor reception channel condition. Satellite access is the last choice when the ground network is unavailable, and improving the user accessibility of the satellite access system is conducive to achieving better user experience.

[0071] This requires that the satellite access system can notify the user of the missed multi media telephony (MMTel) call / message or the failure to receive the call / message in the case that the terminal cannot be contacted in the satellite access system. This notification method is called paging alert, paging robust notification or resilient notification. This notification mechanism or method ensures that the notification of important calls can reach the terminals in the area where the connection fails or is damaged. It can also be understood that it is to improve the robustness of the paging association process in the satellite communication system, and to solve the problem of missing important calls and messages. In some scenarios, the paging alert notification mechanism is used by the network side to notify the terminal in the case of poor satellite access condition. However, how to judge the poor access condition and how to implement the paging alert notification mechanism need to be solved.

[0072] The notification method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings, some embodiments and application scenarios.

[0073] FIG. 4 is a schematic diagram of a notification method provided by an embodiment of the present application. As shown in FIG. 4, the method 200 includes at least part of the following contents:

[0074] S201, the core network device acquires first information.

[0075] S202, performing a first operation according to the first information, the first operation being related to the paging alert notification.

[0076] In some embodiments, the core network device can include but is not limited to at least one of the following:

[0077] AMF, MME.

[0078] In some embodiments, the paging alert notification is a paging alert notification to the first terminal, and the core network device can be a core network device serving the first terminal, for example, a serving AMF.

[0079] It should be noted that in the embodiments of the present application, the paging alert notification can also be replaced by a resilient notification, a paging alert, a paging robust notification, or other expressions, which are not limited in the present application, and can be understood as a highly reliable notification mechanism, such as sending a notification to a user equipment (i.e., a terminal) such as a smart phone in a poor satellite access condition, and the user equipment (i.e., a terminal) can receive such a notification in a poor access condition, which is used to notify the user (or user equipment, terminal) of a downlink call failure or a mobile terminal communication (such as a multimedia telephone, MMTel call) failure, or to notify the user (or user equipment, terminal) of a mobile terminal MMTel call or message that is not received by the user (or user equipment, terminal).

[0080] It should be understood that the first operation related to the paging alert notification can be understood as the first operation for notifying the first terminal by the paging alert manner, for example, the first operation is used to send the paging alert notification, the first operation is used to send a message with the paging alert notification function, and optionally, the message can be implemented by an existing message (such as a paging message), or can also be implemented by a new message, which will be described below.

[0081] Optionally, in the embodiments of the present application, the first operation can also be referred to as a paging alert operation, a paging alert notification operation, a resilient notification operation, or a paging robust notification operation.

[0082] In some embodiments, the first information can be information related to the paging alert, and the first information can be used by the core network device to determine whether to perform the first operation or the timing of performing the first operation. That is, the core network device can decide whether to notify the terminal by the paging alert notification manner or the timing of notifying the terminal by the paging alert notification manner.

[0083] In some implementations, the first information includes at least one of the following:

[0084] The first capability information is used to indicate that the first terminal supports receiving the paging alert notification, or the first terminal supports using the paging alert manner for notification;

[0085] The first subscription information is used to indicate that the first terminal subscribes to use the paging alert notification service;

[0086] The first indication information is used for indicating a state related to the paging early warning service of the first terminal.

[0087] The first indication information is used for indicating a state related to the paging early warning service of the first terminal.

[0088] The first indication information is used for indicating a state related to the paging early warning service of the first terminal.

[0089] In some embodiments, the first capability information can be implemented by binary coding, for example, the first capability information is represented by 1 bit, and different values of the 1 bit are used to indicate whether the first terminal supports receiving the paging early warning notification, for example, a value of 1 indicates that the first terminal supports receiving the paging early warning notification, and a value of 0 indicates that the first terminal does not support receiving the paging early warning notification.

[0090] Optionally, in the case that the first terminal supports receiving the paging early warning notification, the network side device can use the paging early warning mode to notify the terminal, which can also be understood as that the network side device can send the paging early warning notification to the terminal, or in the case that the first terminal does not support receiving the paging early warning notification, the network side device does not use the paging early warning mode to notify the terminal, which can also be understood as that the network side does not send the paging early warning notification to the terminal.

[0091] Optionally, the core network device can determine, according to the first capability information, that in the case that the first terminal supports receiving the paging early warning notification, the paging early warning mode is used to notify the terminal, for example, the paging early warning notification is sent to the first terminal, which can avoid that the terminal misses important calls / messages.

[0092] In some embodiments, the first subscription information can be implemented by binary coding, for example, the first subscription information can be represented by 1 bit, and different values of the 1 bit are used to indicate whether the first terminal subscribes to use the paging early warning notification service, for example, a value of 1 indicates that the first terminal subscribes to use the paging early warning notification service, and a value of 0 indicates that the first terminal does not subscribe to use the paging early warning notification service.

[0093] Optionally, in the case that the first terminal subscribes to use the paging early warning notification service, the network side device can use the paging early warning mode to notify the terminal, or in the case that the first terminal does not subscribe to use the paging early warning notification service, the network side device does not use the paging early warning mode to notify the terminal.

[0094] Optionally, the core network device can determine, according to the first subscription information, that in the case that the first terminal subscribes to use the paging early warning notification service, the paging early warning mode is used to notify the terminal, for example, the paging early warning notification is sent to the first terminal, which can provide appropriate paging early warning notification service for the first terminal, avoid that the terminal misses important calls / messages, improve the user accessibility of the satellite access system, and improve the user experience.

[0095] In some embodiments, the first indication information is used to indicate at least one of:

[0096] The first terminal enters a mode of receiving a paging early warning notification.

[0097] The first terminal starts a mode of only receiving a paging early warning notification.

[0098] The first terminal starts receiving a paging early warning notification.

[0099] The first terminal starts a time period associated with receiving a paging early warning notification.

[0100] The first terminal starts an area associated with receiving a paging early warning notification.

[0101] The first terminal starts a location associated with receiving a paging early warning notification.

[0102] The first terminal starts a data network name (DNN) associated with receiving a paging early warning notification.

[0103] The first terminal starts a network slice associated with receiving a paging early warning notification.

[0104] In some embodiments, the first terminal entering the mode of receiving the paging early warning notification means that the first terminal enters a paging early warning notification mode, and the first terminal can subsequently receive a paging early warning notification from a network side, where the network side can include a core network side and / or an access network side.

[0105] Optionally, the core network device can use a paging early warning mode to notify the first terminal when the first indication information indicates that the first terminal enters the mode of receiving the paging early warning notification, which is conducive to ensuring that the core network device uses the paging early warning notification to notify the terminal under appropriate conditions, avoids the terminal missing important calls / messages, and improves user accessibility of the satellite access system.

[0106] In some embodiments, the first terminal starting the mode of only receiving the paging early warning notification means that the first terminal only starts the paging early warning notification mode, and the network side can only notify the first terminal through the paging early warning notification, where the network side can include a core network side and / or an access network side.

[0107] Optionally, the core network device can use a paging early warning mode to notify the first terminal when the first indication information indicates that the first terminal starts the mode of only receiving the paging early warning notification, which is conducive to ensuring that the core network device uses the paging early warning notification to notify the terminal under appropriate conditions, thereby avoiding the terminal missing important calls / messages, improving user accessibility of the satellite access system, and improving user experience.

[0108] In some embodiments, the first terminal enabling receiving the paging early warning notification indicates that the first terminal can receive the paging early warning notification from the network side, where the network side can include the core network side and / or the access network side.

[0109] Optionally, the core network device can determine to notify the first terminal using the paging early warning mode in a case where the first terminal enables receiving the paging early warning notification, which is beneficial to ensure that the core network device uses the paging early warning notification to notify the terminal under appropriate conditions, thereby avoiding the terminal from missing important calls / messages, improving user accessibility of the satellite access system, and improving user experience.

[0110] In some embodiments, the first terminal enabling receiving the paging early warning notification can correspond to specific conditions, such as a specific time period, region, location, DNN, or network slice. The core network device can determine whether to notify the first terminal using the paging early warning mode according to a time period, region, location, DNN, or network slice associated with the first terminal enabling receiving the paging early warning notification, which is beneficial to the core network device to use the paging early warning notification to notify the terminal at an appropriate time, thereby avoiding the terminal from missing important calls / messages, improving user accessibility of the satellite access system, and improving user experience. For example, if the current time period is within the time period associated with the first terminal enabling receiving the paging early warning notification, the first terminal is notified using the paging early warning mode, otherwise, the first terminal is not notified using the paging early warning mode. For another example, if the current region where the first terminal is located is within the region associated with the first terminal enabling receiving the paging early warning notification, the first terminal is notified using the paging early warning mode, otherwise, the first terminal is not notified using the paging early warning mode. For another example, if the current location where the first terminal is located is within the location associated with the first terminal enabling receiving the paging early warning notification, the first terminal is notified using the paging early warning mode, otherwise, the first terminal is not notified using the paging early warning mode. For another example, if the current DNN associated with the first terminal is within the DNN associated with the first terminal enabling receiving the paging early warning notification, the first terminal is notified using the paging early warning mode, otherwise, the first terminal is not notified using the paging early warning mode.

[0111] In some embodiments, the response information of the first terminal to the paging message includes at least one of the following:

[0112] The core network device pages the first terminal N times without receiving the response information of the first terminal, where N is a positive integer.

[0113] The core network device pages the first terminal for a first time period without receiving the response information of the first terminal.

[0114] The core network device determines that paging the first terminal fails.

[0115] Optionally, when the core network device pages the first terminal N times and does not receive response information of the first terminal, the core network device can determine that the first terminal cannot receive the paging message, for example, the receiving channel state of the first terminal is poor, in this case, the core network device uses the paging warning mode to notify the first terminal, which is beneficial to ensure that the core network device uses the paging warning notification to notify the terminal under appropriate conditions, thereby avoiding the terminal missing important calls / messages, improving the user accessibility of the satellite access system, and improving the user experience.

[0116] It should be noted that paging the first terminal N times and not receiving response information of the first terminal can include, but is not limited to, at least one of the following scenarios:

[0117] Scenario 1: The paging message is paged N times (i.e., sent N times) on the air interface, and no response is received from the first terminal.
