[0182] 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).

[0183] In some embodiments, in suburban and rural scenarios, shadow fading and clutter loss may occur, and the non-line of sight (NLOS) caused by clutter loss may reach over 18 dB.

[0184] In some embodiments, line-of-sight probability indicates that at an altitude of 30 degrees, approximately 10% of rural users and 50% of urban users will experience NLOS. For terminal-initiated services, users can consciously choose a good location to initiate calls to avoid NLOS. However, for network-initiated services, missing paging due to poor signal conditions at the user's location can impact critical services such as emergency calls.

[0185] In some embodiments, in normal operation, when the UE is in idle mode and wakes up to monitor its paging occasion, the UE needs to correctly detect the SSB in order to continue monitoring its paging occasion. When the NLOS loss is as high as 18dB, the UE is usually 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 the UE's response. In a severe NLOS channel, the UE will not respond and T3513 expires, which means that the paging attempt has failed. After a certain number of failed attempts, the network will eventually give up the paging effort.

[0186] In some embodiments, it is important to send paging calls and short messages to those UEs under adverse reception channel conditions, as this will greatly improve the user experience in non-terrestrial network (NTN) communication systems, especially for those public safety services.

[0187] In some embodiments, a robust paging notification alert is introduced to send a paging message or short message to the UE under severe NLOS channel conditions when the NR SSB cannot be fully detected. The robust notification alert is a downlink-only physical channel with its own built-in system information and synchronization signals, and its operating signal-to-interference plus noise ratio (SNR) is much lower than that of the traditional NR physical downlink channel. In order to reliably deliver the paging call, the network will have to switch to a reliable notification alert after a certain number of failed traditional paging attempts. When the UE receives the robust paging notification alert, the UE can move to a better reception position and respond to the normal paging call.

[0188] It should be noted that, given the additional network resource consumption of the robust notification alert, it is not necessary to apply it to all use cases. It is triggered under specific conditions and can be canceled when the UE moves into the LOS area.

[0189] In the related art, it is unclear how to cancel the robust notification alert of a UE when the UE moves to a better reception location and responds to a normal paging call.

[0235] In some embodiments, a paging response message is received within the timing duration of a second timer, and the first core network device determines whether the first condition is met, where the second timer is a paging waiting timer.

[0236] In some embodiments, upon detecting termination of a service application, the first core network device determines whether a first condition is satisfied, and the service application applies the first operation.

[0237] In some embodiments, when a change in the access type of the terminal is detected, the first core network device determines whether the first condition is met.

[0349] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:

[0350] In some embodiments, a robust notification alert cancel timer (corresponding to a first timer, robust notification alert cancel timer) is introduced to determine how long the robust notification alert is applied to the UE. When the core network determines to apply a robust notification alert to the UE, the robust notification alert cancel timer is set.

[0351] In some embodiments, robust notification alert subscription information for a UE may be configured:

[0352] To which service application the robust notification alert is applied;

[0354] The time period for applying robust notification alerts;

[0355] Robust notification alerts regions of interest.

[0356] In some embodiments, a core network entity (e.g., AMF in the context of 5GC) determines to cancel a UE's robust notification alert based on the following criteria:

[0357] Robust notification alarm cancel timer stopped;

[0358] The core network entity (e.g. AMF in the 5GC context) receives a paging response from the UE within the T3513 timer.

[0359] Detecting the shutdown of subscription service applications with robust notification alerts applied;

[0361] The subscription time window for applying robust notification alerts has been passed;

[0362] Detecting UE movement out of the area of ​​interest applies robust notification alerts.

[0363] In some embodiments, when at least one of the above criteria is matched, the core network entity (e.g., AMF in the 5GC context) determines to cancel the robust notification alarm for the UE.

[0364] In some embodiments, in order to detect the cessation of a subscribed service application to which a robust notification alert is applied, a core network entity (e.g., AMF in the 5GC context) subscribes to an SMF for a service stop event.

[0366] In some embodiments, in order to detect that the UE moves out of the area of ​​interest to which the robust notification alarm is applied, the core network entity (e.g., the AMF under the 5GC context) determines that the UE moves out of the area of ​​interest to which the robust notification alarm is applied based on the reported ULI.
