[0225] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0226] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0227] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0228] In the communication system, non-terrestrial network (NTN) is an important technology in 5G. NTN can provide wireless resources through satellites (or drones) instead of ground base stations. Figure 2A is a schematic diagram of the framework of a GNSS measurement system provided by an embodiment of the present disclosure. As shown in Figure 2A, the GNSS measurement system includes a terminal device, which can also be called user equipment (UE), beam projection, service link, satellite, unmanned aircraft system (UAS) platform, feeder link, gateway, data network and satellite field of view. According to the different ways in which the satellite processes signals, it can be divided into transparent transmission mode and regeneration mode.

[0229] In one embodiment of the present disclosure, Figure 2B is a schematic diagram illustrating an example of a transparent transmission mode provided by an embodiment of the present disclosure. As shown in Figure 2B, the NTN ground station transmits the signal from the next generation NodeB (gNB) to the satellite. The satellite converts the signal to the satellite frequency band and then transmits it to the UE via the satellite frequency band. Besides frequency conversion and signal amplification, the satellite does not demodulate the gNB signal. The satellite can be similar to a repeater. A 5G base station, called a gNB, provides the UE with a terminal node for the New Radio (NR) user and control plane protocols and is connected to the 5G core network (5GC) via the NG interface.

[0230] In one embodiment of the present disclosure, Figure 2C illustrates an example of a retransmission mode. As shown in Figure 2C, after the NTN ground station sends the gNB signal to the satellite, the satellite first demodulates and decodes the signal, then re-encodes and modulates it (a process known as regeneration), and transmits the regenerated signal via the satellite frequency band.

[0231] In one embodiment of the present disclosure, Table 1 shows the satellite altitude, orbit, and satellite coverage of a typical NTN network provided by the embodiment of the present disclosure:

[0232] Table 1

[0233] In some embodiments, in suburban and rural scenarios, shadow fading and clutter loss may exist. Due to clutter loss, the non-light of sight (NLOS) can exceed 18dB.

[0234] In some embodiments, the Light of Sight (LOS) probability indicates that at an altitude of 30 degrees, approximately 10% of rural users and 50% of urban users will experience NLOS. For outgoing calls, users can consciously choose a good location to initiate calls to avoid NLOS. However, for incoming calls, users with poor reception conditions may miss emergency paging calls and messages.

[0235] In some embodiments, for example, in normal operation, when a terminal is in idle mode or inactive state and wakes up to monitor its paging occasion, the terminal needs to correctly detect the Synchronization Signal Block (SSB) before it can continue to monitor its paging moment. When the NLOS loss is as high as 18dB, the terminal is typically unable to detect the SSB and eventually declares a Radio Link Failure (RLF) even if it is still within the coverage of the satellite beam. When the network attempts to send a normal paging in the legacy New Radio (NR) physical downlink channel, it will start the T3513 timer and wait for a response from the terminal. In severe non-line-of-sight channels, there will be no response from the terminal and T3513 expires, which means that the paging attempt has failed. After a certain number of failed attempts, the network equipment will eventually give up the paging effort.

[0236] In some embodiments, it is important to deliver paging calls and short messages to these terminals under adverse reception channel conditions, as this will greatly improve the user experience in the NTN communication system, especially for those public safety services.

[0237] In some embodiments, in the case of severe non-line-of-sight channels, when the NR SSB cannot be fully detected, an enhanced paging notification alert is introduced to send a paging message or short message to the terminal. The enhanced paging alert is a physical channel with only downlink, which has its own built-in system information and synchronization signal, and operates at a much lower signal-to-noise ratio (SNR) than the traditional NR physical downlink channels. In order to reliably deliver paging calls, the network must switch to the enhanced paging alert after a certain number of traditional paging attempts fail. When the terminal receives the enhanced paging notification alert, the terminal can move to a better reception position and respond to the normal paging call.

[0238] In some embodiments, in response to Radio Access Network (RAN) paging of an inactive terminal, the network device triggers a transition from RRC_INACTIVE to RRC_CONNECTED, where RRC_INACTIVE is a state in which the terminal remains in CM-CONNECTED and can move within the area configured by the NG-RAN (RNA) without notifying the NG-RAN. In RRC_INACTIVE, the last serving gNB node maintains the terminal context and the terminal's next-generation NG connection associated with the serving AMF and UPF.

[0239] If the last serving gNB receives DL data from the UPF or DL ​​terminal-related signaling (except for the Terminal Context Release Command message) from the AMF while the terminal is in RRC_INACTIVE, it pages the cell corresponding to the RNA. If the RNA includes the cell of a neighboring gNB, it may send an XnAP RAN paging to the neighboring gNB. Figure 2D is an example diagram of a network device-triggered transition from RRC_INACTIVE to RRC_CONNECTED, as provided in an embodiment of the present disclosure. As shown in Figure 2D, this includes:

[0240] 1. A RAN paging trigger event occurs (incoming DL user plane, DL signaling from 5GC, etc.).

[0241] 2. Triggering RAN paging; only in the cell controlled by the last serving gNB or also via Xn RAN paging in cells controlled by other gNBs configured to the terminal in the RAN-based Notification Area (RNA).

[0242] 3. Use the Inactive Radio Network Temporary Indentifier (I-RNTI) to page the terminal.

[0243] 4. If the terminal has been successfully reached, it attempts to recover from RRC_INACTIVE as described in some embodiments.

[0244] In some embodiments, enhanced paging can be used for terminal paging under severe non-line-of-sight channel conditions where NR-SSB cannot be fully detected. Robust paging may consume additional network resources. If the terminal is in the RRC_INACTIVE state, the last serving base station receives downlink data or downlink signaling from the core network, which may trigger paging in the RNA (RAN notification area). How the last serving base station confirms the execution of enhanced paging (robust paging) is an urgent problem to be solved.

[0245] An enhanced paging confirmation method, apparatus, device, and storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0246] FIG3A is a schematic diagram of an interaction of an enhanced paging confirmation method provided by an embodiment of the present disclosure. As shown in FIG3A , the method may include the following steps:

[0247] Step S3101: A core network device sends a first message to a first node, where the first message is at least one of a message for requesting to establish a terminal context, a message for requesting to modify a terminal context, and a message related to paging, and includes first robust paging assistance information (robust paging assistance information).
