In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0310] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0313] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0314] 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 paging methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0315] Optionally, a non-terrestrial network (NTN) system is introduced in the 5G communication system. The NTN system is widely used in the communication field due to its wide coverage, strong disaster resistance and large capacity. In the NTN system, wireless resources can be provided to the terminal by satellite (or drone). In addition, in the NTN system, the network device also needs to page the terminal. Optionally, under normal circumstances, the method for the network device to paging the terminal (hereinafter referred to as traditional paging or legacy paging or normal paging) may include: when the network device wants to perform related services on the terminal in an inactive state (INACTIVE) or idle state (IDLE), the network device sends a paging message to the terminal, the terminal receives the paging message, and accesses the network device to perform related services by responding to the paging message. In some embodiments, when the network device sends a paging message to the terminal, the network device will start the T3513 timer. When the network device receives a response from the terminal to the paging message during the operation of the T3513 timer, it is determined that the paging is successful. If the T3513 timer times out and the network device still has not received a response from the terminal to the paging message, it is determined that the paging has failed.

[0316] In some embodiments, in special scenarios within the NTN system (e.g., when a terminal is located in a suburban or rural area, or when the terminal is placed in a pocket, backpack, vehicle, or boat), paging failures to the terminal may occur due to shadow fading and clutter loss. Specifically, in some embodiments, Line of Sight (LoS) probability indicates that at an altitude of 30 degrees, approximately 10% of rural users and 50% of urban users experience Non-Line of Sight (NLOS) between the terminal and network devices, and clutter loss may result in NLOS exceeding 18 decibels (dB) between the terminal and the network device. When the NLOS loss reaches 18 dB, even if the terminal is still within the coverage area of ​​the satellite beam, it may still fail to detect the Single Side Band (SSB) signal, resulting in a Radio Link Failure (RLF). At this time, if the network device sends a paging message to the terminal, the terminal may not be able to respond to the paging message of the network device due to the inability to detect the paging message. In addition, if the network device does not receive a response to the paging message from the terminal for a long time, it will determine that the paging has failed and will page again. After a certain number of failed attempts, the network device will give up paging the terminal, which will result in a low paging success rate for the terminal in special scenarios of the NTN system, affecting the communication efficiency and communication services (such as public safety services) of the terminal.

[0317] In some embodiments, to improve the paging success rate of a terminal, robust paging is introduced. Under robust paging, a network device may send a robust paging notification alert to the terminal to achieve successful paging of the terminal under severe NLOS channel conditions. Optionally, the robust paging notification alert may be a downlink physical channel that includes its own built-in system information and synchronization signal. For example, at least one of the information carried, physical resources, number of repetitions, and transmit power of the enhanced paging notification signal may be different from those of the above-mentioned traditional paging (or legacy paging, normal paging). For another example, the enhanced paging is implemented through a new synchronization signal and traditional paging. Alternatively, for another example, the signal-to-noise ratio (SNR) of the physical downlink channel of the enhanced paging notification signal may be much lower than the SNR of the physical downlink channel of traditional paging. Optionally, in some embodiments, the enhanced paging notification signal can be understood as an enhancement to traditional paging. Compared to traditional paging, the enhanced paging notification signal is more likely to be detected by the terminal under severe NLOS channel conditions, and can minimize the additional loss compared to the link margin required under line-of-sight conditions. Therefore, in some embodiments, after a certain number of traditional paging (legacy paging or normal paging) attempts fail, the network device can send an enhanced paging notification signal to the terminal, so that when the terminal receives the enhanced paging notification signal, it can move to a location with better channel conditions to correctly receive traditional paging or access the network, thereby improving the terminal's paging success rate.

[0318] However, currently, when performing robust paging notification between a terminal and a network device, how to specifically determine the occasion for the robust paging notification is a technical problem that needs to be solved urgently.

[0319] Based on this, the present disclosure provides a paging method for determining a timing for paging enhancement notification, so that the paging enhancement notification can be successfully implemented between a terminal and a network device based on the timing.

[0320] FIG2A is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0321] Step 2101: The terminal and / or the network device determines the system frame corresponding to the second paging as the first time domain position, or the terminal and / or the network device determines the second paging opportunity corresponding to the second paging as the first time domain position.

[0322] Optionally, the second paging can be used for normal paging of the terminal. The normal paging can be, for example, the legacy paging (legacy paging or normal paging) described before the embodiment of FIG. 2A. For a detailed introduction to the normal paging, please refer to the description before the embodiment of FIG. 2A and will not be repeated here.

[0323] Optionally, the above-mentioned “system frame corresponding to the second paging” can be understood as the system frame where the second paging is located, that is, on which system frame the network device performs the second paging.

[0324] Optionally, the aforementioned "second paging occasion corresponding to the second paging" can be understood as the paging occasion where the second paging occurs, that is, at which paging occasion the network device performs the second paging. Specifically, in some embodiments, a system frame may include at least one paging occasion (PO), and the network device may perform the second paging at at least one paging occasion in at least one system frame.

[0325] Optionally, the above-mentioned "system frame corresponding to the second paging, the second paging opportunity corresponding to the second paging" may be predefined by the protocol, or may be configured and / or indicated to the terminal after determination by the network device. For example, the network device may configure and / or indicate the "system frame corresponding to the second paging, the second paging opportunity corresponding to the second paging" to the terminal through a system message and / or a dedicated Radio Resource Control (RRC) message.

[0326] Optionally, the first time domain location may include a first paging occasion corresponding to the first paging, wherein the first paging may be used to implement robust paging notification for the terminal, and the first paging occasion may be a robust paging notification occasion. Optionally, the first paging may be, for example, the robust paging described previously in the embodiment of FIG. 2A . In some embodiments, the first paging may be an enhanced paging for the second paging. Optionally, the first paging and the second paging differ in at least one of the following: associated synchronization signals, carried information, physical layer processing methods, physical resources, repetition times, and transmit power. For example, the SNR of the physical downlink channel of the first paging may be significantly lower than the SNR of the physical downlink channel of the second paging. Furthermore, compared to the second paging, the first paging is more likely to be responded to by the terminal under severe NLOS channel conditions. For example, compared to the second paging, the first paging is more likely to be responded to by the terminal under severe NLOS channel conditions in non-terrestrial wireless access coverage. For a detailed introduction to enhanced paging, please refer to the description before the embodiment of FIG. 2A , which will not be repeated here.

[0327] Optionally, the above-mentioned “first paging occasion corresponding to the first paging” can be understood as the paging occasion where the first paging occurs, that is, at which paging occasion the network device performs the first paging.

[0328] Optionally, in some embodiments, the execution operation corresponding to the above-mentioned "determining the system frame corresponding to the second paging as the first time domain position" may, for example, be: determining the system frame number (SFN) of the system frame corresponding to the second paging as the SFN of the system frame corresponding to the first paging; the execution operation corresponding to the above-mentioned "determining the second paging opportunity corresponding to the second paging as the first time domain position" may, for example, be: determining the paging opportunity index (PO index) of the second paging opportunity in the SFN corresponding to the second paging as the paging opportunity index (PO index) of the first paging opportunity in the SFN corresponding to the first paging.

[0329] Optionally, in some embodiments, the above “determining the system frame corresponding to the second paging as the first time domain position, or determining the second paging opportunity corresponding to the second paging as the first time domain position” means that the time domain positions of the first paging and the second paging are the same.

[0330] It should be noted that in some embodiments, the network device and / or the terminal may determine to use the above step 2101 to determine the first time domain position based on protocol pre-definition, or the network device may determine to use the above step 2101 to determine the first time domain position, and instruct and / or configure the terminal to use the above step 2101 to determine the first time domain position. For example, the network device may instruct and / or configure the terminal to use the above step 2101 to determine the first time domain position through a system message and / or a dedicated RRC message. This disclosure is not limited to this.

[0331] Step 2102: The network device performs a first paging at a first time domain position.

[0332] Optionally, the network device may perform a first paging on the terminal at a first time domain location. For example, the network device may send a paging message for the first paging to the terminal at the first time domain location. For a detailed description of the first paging, refer to the aforementioned step description. Furthermore, the terminal may monitor the first paging at the first time domain location.

[0333] In the above embodiment, the terminal and / or the network device will determine the first time domain position corresponding to the first paging, wherein the first paging is used to implement the terminal's paging robust notification, and the first time domain position includes the first paging occasion corresponding to the first paging, and the first paging occasion is the occasion of the paging robust notification. And, after the terminal and / or the network device determines the first time domain position, the network device will perform the first paging at the first time domain position, and the terminal will listen to the first paging at the first time domain position. It can be seen that the present disclosure provides a paging method for determining the occasion of the paging robust notification, so that the network device can successfully perform the paging robust notification on the terminal at the occasion of the paging robust notification, and the terminal can successfully listen to the paging robust notification at the occasion of the paging robust notification, thereby successfully implementing the paging robust notification for the terminal. Then, when the network device fails to perform traditional paging on the terminal for many times, the method disclosed in the present invention can be used to perform enhanced paging notification on the terminal. Since the enhanced paging notification is an enhancement of traditional paging, it is more likely to be responded to by the terminal. Therefore, the paging success rate of the terminal is greatly improved, and the communication efficiency of the terminal is ensured.

[0334] The paging method involved in the embodiment of the present disclosure may include at least one of steps 2101 to 2102. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and step 2101+S2102 may be implemented as an independent embodiment, but are not limited thereto.

[0335] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0336] FIG2B is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0337] Step 2201: The terminal and / or network device determines a first system frame.

[0338] Optionally, the first system frame may be a system frame in which the first paging occasion is located. For a detailed description of the "first paging occasion", reference may be made to the description of the above embodiment.

[0339] Optionally, in some embodiments, the terminal and / or network device may determine the system frame corresponding to the second paging as the first system frame. That is, the SFN of the first system frame may be determined as the SFN corresponding to the second paging. For a detailed description of the "system frame corresponding to the second paging," please refer to the above embodiments.

[0340] In other embodiments, the terminal and / or network device may determine the system frame corresponding to the second paging as the first system frame after the system frame is offset by the first offset value. That is, the SFN of the first system frame = the SFN corresponding to the second paging ± the first offset value. Optionally, the first offset value may be predefined by the protocol, or the first offset value may be determined by the network device and configured and / or indicated to the terminal. For example, the network device may configure and / or indicate the first offset value to the terminal via a system message and / or a dedicated RRC message.

[0341] In some further embodiments, the terminal and / or the network device may determine the first system frame based on the paging cycle T of the first paging, the number of system frames N in the paging cycle of the first paging, the first value, and the second offset value. Optionally, in some embodiments, the following formula 1 may be used to calculate the system frame number SFN corresponding to the first system frame based on the paging cycle T of the first paging, the number of system frames N in the paging cycle of the first paging, the first value, and the second offset value, and determine the first system frame based on the SFN; wherein the formula 1 may be: (SFN+NF_offset)mod T=(T div N)*(UE_ID mod N);

[0342] If N=1, the above formula 1 may be: SFN mod T=NF_offset.

[0343] wherein, the div function can be used to perform integer division; the mod function is a remainder function; the above-mentioned N can be, for example, 1, 2; the above-mentioned NF_offset is a second offset value, and the second offset value is 0 or a non-zero value; the above-mentioned UE_ID is a first value, and the first value is determined based on the first identifier of the terminal; optionally, the first identifier of the terminal may include the terminal identifier of the terminal and / or the fifth generation mobile communication technology system architecture evolution temporary mobile user identifier (5th generation mobile communication system System Architecture Evolution-Temporary Mobile Subscriber Identity, 5G-S-TMSI) of the terminal; wherein, the first value is determined based on the first identifier of the terminal, for example, including: determining the terminal identifier of the terminal as the first value, or calculating the first value based on the terminal identifier and / or 5G-S-TMSI, optionally, the first value UE_ID can be calculated based on the terminal identifier and / or 5G-S-TMSI using a formula:

[0344] UE_ID can be:

[0345] UE_ID: terminal identifier mod 1024.

[0346] UE_ID: 5G-S-TMSI mod 1024.

[0347] Optionally, the paging cycle T of the first paging, the number N of system frames within the paging cycle of the first paging, the method for determining the first value, and the second offset value mentioned above can be predefined by the protocol, or can be configured and / or indicated to the terminal after the network device determines it. For example, the network device can configure and / or indicate at least one of the paging cycle T of the first paging, the number N of system frames within the paging cycle of the first paging, the method for determining the first value, and the second offset value to the terminal through a system message and / or a dedicated RRC message.

[0348] Step 2202: The terminal and / or network device determines a first paging occasion from a first system frame.

[0349] Optionally, a system frame may include at least one paging occasion, and the terminal and / or the network device may determine one or more paging occasions in the first system frame as the first paging occasion.

[0350] In some embodiments, when the first system frame includes one paging opportunity, the one paging opportunity may be determined as the first paging opportunity. In this case, the paging opportunity index of the first paging opportunity in the first system frame is a fixed value, for example, fixed to 0 or 1.

[0351] In other embodiments, a first index may be determined based on the number X of system frames in the paging cycle of the second paging, the number Y of paging occasions in a system frame, and a first value. The first index may be the index of the first paging occasion in the first system frame. Subsequently, the first paging occasion is determined from the first system frame based on the first index. Optionally, the first index may be calculated based on Formula 2, which may be: Index = floor(UE_ID / X) mod Y.

[0352] Among them, Index is the first index, UE_ID is the first value, and floor function is a rounding-down function.

[0353] It should be noted that the above “number Y of paging occasions in one system frame” may be, for example: number Y of paging occasions in one system frame in the second paging process. Optionally, Y may be, for example, 1, 2, 3, or 4.

[0354] Optionally, the number X of system frames in the paging cycle of the second paging and the number Y of paging occasions in one system frame may be predefined by a protocol, or may be determined and configured by the network device and / or indicated to the terminal. For example, the network device may configure and / or indicate at least one of the number X of system frames in the paging cycle of the second paging and the number Y of paging occasions in one system frame to the terminal via a system message and / or a dedicated RRC message.

[0355] In some other embodiments, the first paging occasion can be determined from the first system frame based on the position of the second paging occasion in the system frame corresponding to the second paging occasion, wherein the position of the first paging occasion in the first system frame is the same as the position of the second paging occasion in the system frame corresponding to the second paging occasion.

[0356] In some further embodiments, a starting subframe position of the first paging opportunity in the first system frame may be determined based on the SFN of the first system frame, the third offset value, and the paging cycle T of the first paging; and the first paging opportunity may be determined based on the starting subframe position. Optionally, the starting subframe position may be calculated based on the following formula 3, which may be: (SFN+subframe number) mod T=subframe_offset;

[0357] Wherein, subframe number is used to indicate the starting subframe position of the first paging occasion in the first system frame, and subframe_offset is a third offset value, which is 0 or a non-zero value. Optionally, the third offset value may be predefined by the protocol, or the third offset value may be determined and configured by the network device and / or indicated to the terminal. For example, the network device may configure and / or indicate the third offset value to the terminal via a system message and / or a dedicated RRC message.

[0358] Step 2203: The terminal and / or the network device determines the first paging occasion as the first time domain position.

[0359] For a detailed description of the first time domain position, please refer to the above embodiment description.

[0360] It can be seen from the above content that the terminal and / or network device can determine the first time domain position by executing the above steps 2201-2203. Optionally, it should be noted that in some embodiments, the network device and / or terminal may determine the first time domain position based on the protocol pre-definition using the above steps 2201-2203, or the network device may determine the first time domain position using the above steps 2201-2203, and instruct and / or configure the terminal to use the above steps 2201-2203 to determine the first time domain position. For example, the network device may instruct and / or configure the terminal to use the above steps 2201-2203 to determine the first time domain position through a system message and / or a dedicated RRC message. This disclosure is not limited to this.

[0361] Step 2204: The network device performs a first paging at a first time domain position.

[0362] Optionally, the network device may perform a first paging on the terminal at a first time domain location. For example, the network device may send a paging message for the first paging to the terminal at the first time domain location. For a detailed description of the first paging, refer to the aforementioned step description. Furthermore, the terminal may monitor the first paging at the first time domain location.

[0363] In the above embodiment, the terminal and / or the network device will determine the first time domain position corresponding to the first paging, wherein the first paging is used to implement the terminal's paging robust notification, and the first time domain position includes the first paging occasion corresponding to the first paging, and the first paging occasion is the occasion of the paging robust notification. And, after the terminal and / or the network device determines the first time domain position, the network device will perform the first paging at the first time domain position, and the terminal will listen to the first paging at the first time domain position. It can be seen that the present disclosure provides a paging method for determining the occasion of the paging robust notification, so that the network device can successfully perform the paging robust notification on the terminal at the occasion of the paging robust notification, and the terminal can successfully listen to the paging robust notification at the occasion of the paging robust notification, thereby successfully implementing the paging robust notification for the terminal. Then, when the network device fails to perform traditional paging on the terminal for many times, the method disclosed in the present invention can be used to perform enhanced paging notification on the terminal. Since the enhanced paging notification is an enhancement of traditional paging, it is more likely to be responded to by the terminal. Therefore, the paging success rate of the terminal is greatly improved, and the communication efficiency of the terminal is ensured.

[0364] The paging method involved in the embodiments of the present disclosure may include at least one of steps 2201 to 2204. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, step 2203 may be implemented as an independent embodiment, and step 2201+S2202 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0365] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0366] FIG2C is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0367] Step 2301: The network device randomly determines a first time domain position.

[0368] For a detailed description of the first time domain position, please refer to the above embodiment description.

[0369] Step 2302: The network device determines the period of the first time domain position.

[0370] Step 2303: The network device determines the i-th first time domain position based on the first first time domain position and the period of the first time domain position, where i is an integer greater than 1.

[0371] Optionally, assuming that the period of the first time domain position is T1, the network device can determine the time domain position after the T1 duration of the first first time domain position as the second first time domain position, and determine the time domain position after the T1 duration of the second first time domain position as the third first time domain position, and so on, until all the first time domain positions are determined.

[0372] Step 2304: The network device performs a first paging on the terminal at the first time domain position.

[0373] Optionally, the network device may send a paging message of the first paging to the terminal at the first first time domain location and / or the i-th first time domain location. In some embodiments, the public land mobile network (PLMN) corresponding to the paging message of the first paging may be the PLMN of the terminal. For a detailed description of the first paging, refer to the aforementioned step description.

[0374] Optionally, in some embodiments, the network device may perform a first paging on the terminal at a first frequency, and the first frequency may be a frequency used for the first paging; or, in other embodiments, the network device may perform a first paging on the terminal at a first frequency domain position, and the first frequency domain position is a frequency domain position used for the first paging. Optionally, the first frequency domain position may include a frequency point and / or a bandwidth, for example; or, in still other embodiments, the network device may perform a first paging on the terminal at a first synchronization sequence, and the first synchronization sequence may be a synchronization sequence used for the first paging.

[0375] The first frequency, the first frequency domain position, and the first synchronization sequence may be predefined by a protocol, or the first frequency, the first frequency domain position, and the first synchronization sequence may be determined by a network device and configured and / or indicated to the terminal. For example, the network device may configure and / or indicate at least one of the first frequency, the first frequency domain position, and the first synchronization sequence to the terminal through a system message and / or a dedicated RRC message.

[0376] Step 2305: The terminal monitors the first paging.

[0377] Optionally, in some embodiments, when a terminal monitors a first paging, it may first determine a first first time domain location based on a blind search. For example, the terminal may blindly detect the first paging on a first frequency; or blindly detect the first paging on a first frequency domain location; or blindly detect the first paging on a first synchronization sequence. When the terminal determines that the PLMN corresponding to a detected paging message of a first paging is the terminal's PLMN, the paging message of the first paging is considered to be a paging message that needs to be monitored. At this time, the terminal determines that it has monitored the first paging, and the terminal may determine the paging opportunity corresponding to the detected paging message of the first paging as the first first time domain location. Subsequently, the terminal may determine the period of the first time domain location based on protocol pre-definition and / or based on the configuration or instruction of the network device, and determine the i-th first time domain location based on the first first time domain location and the period of the first time domain location, where i is an integer greater than 1. The terminal may subsequently monitor the first paging at the i-th first time domain location.

[0378] Optionally, at least one of the first frequency, the first frequency domain position, and the first synchronization sequence may be determined by the terminal based on protocol predefinition, and / or may be determined by the terminal based on configuration or instruction of a network device.

[0379] In the above embodiment, the terminal and / or the network device will determine the first time domain position corresponding to the first paging, wherein the first paging is used to implement the terminal's paging robust notification, and the first time domain position includes the first paging occasion corresponding to the first paging, and the first paging occasion is the occasion of the paging robust notification. And, after the terminal and / or the network device determines the first time domain position, the network device will perform the first paging at the first time domain position, and the terminal will listen to the first paging at the first time domain position. It can be seen that the present disclosure provides a paging method for determining the occasion of the paging robust notification, so that the network device can successfully perform the paging robust notification on the terminal at the occasion of the paging robust notification, and the terminal can successfully listen to the paging robust notification at the occasion of the paging robust notification, thereby successfully implementing the paging robust notification for the terminal. Then, when the network device fails to perform traditional paging on the terminal for many times, the method disclosed in the present invention can be used to perform enhanced paging notification on the terminal. Since the enhanced paging notification is an enhancement of traditional paging, it is more likely to be responded to by the terminal. Therefore, the paging success rate of the terminal is greatly improved, and the communication efficiency of the terminal is ensured.

[0380] The paging method involved in the embodiments of the present disclosure may include at least one of steps 2301 and 2302. For example, step 2301 may be implemented as an independent embodiment, step 2302 may be implemented as an independent embodiment, step 2303 may be implemented as an independent embodiment, and step 2301+step 2302 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0547] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, the first device side, the network device side, etc., which will not be repeated here.

[0548] The paging method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5104. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0549] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0550] The following is an exemplary introduction to the above method.

[0551] Currently, it is still unclear how a UE (ie the aforementioned terminal) determines its own paging robust notification occasion. The present invention provides a method for a UE to determine its own paging robust notification occasion.

[0552] Optional embodiment: The UE determines its own paging robust notification occasion, and monitors the paging robust notification message on the determined occasion.

[0553] Optional embodiment 1: The UE uses the determined PO as a paging robust notification occasion.

[0554] Example: The UE uses the SFN of the paging occasion and the specific PO index in the SFN as the notification frame of the paging robust notification and the occasion index in the frame.

[0555] Optional embodiment 2: The UE uses the paging frame of the paging occasion as the notification frame of the paging robust notification occasion, but separately determines the notification occasion index in the notification frame.

[0556] Example: The occasion index of the paging robust notification occasion in the SFN is fixed to 0 or 1, which is applicable to the case where there is only one occasion in a notification frame.

[0557] Optional embodiment 2.1: The specific time domain location of the paging robust notification occasion within the SFN is calculated based on the UE ID.

[0558] Embodiment: The UE ID is a UE ID used for paging Robust notification occasion (PRNO) or is calculated based on the UE ID, or is calculated based on the 5G-S-TMSI.

[0559] Example: The index of PRNO in a paging robust notification frame is determined by the following formula: Index = floor (UE_ID / X) mod Y

[0560] Note: X is the number of paging frames within the paging cycle T, and Y is the number of POs within a paging frame. Y is determined by the system, such as 1, 2, 3, or 4, or by network configuration.

[0561] Optional embodiment 3: the UE adds an offset to the SFN of the paging occasion as the SFN of the paging Robust notification occasion. The specific time domain position of the paging Robust notification occasion within the SFN is the same as the specific time domain position of the paging within the SFN, or is determined separately.

[0562] Example: If PRNO is determined separately, the specific method is the same as that of invention point 2.2.

[0563] Optional embodiment 4: The UE determines the notification frame based on the notification period T of the paging robust notification and the number N of notification frames in a notification.

[0564] Example: Notification Frame is determined by the following formula: (SFN+NF_offset) mod T = (T div N) * (UE_ID mod N)

[0565] Note: The UE ID is the UE ID used for paging Robust notification occasion (PRNO) or is calculated based on the UE ID or based on the 5G-S-TMSI.

[0566] Optional embodiment 4.1: T is the period of paging robust notification configured by the network through a system message or a dedicated RRC message.

[0567] Optional embodiment 4.2: N is the number of notification frames in one period configured by the network through a system message or a dedicated RRC message, or the number of notification frames in one period agreed by the system, such as 1 or 2.

[0568] Example: The index of the PO of the UE within a PRNO is determined according to the example of sub-invention point 2.2.

[0569] Optional embodiment 4.3: NF_offset is the frame offset of the paging robust notification configured by the network through a system message or a dedicated RRC message.

[0570] Example: Offset is optional and may not be included in the calculation formula.

[0571] Example: If N=1, the notification frame satisfies one of the following formulas: SFN mod T=NF_offset

[0572] Optional embodiment 4.4: The starting subframe position of a notification occasion in a notification frame is determined as follows: (SFN+subframe number) mod T=subframe_offset

[0573] Example: Subframe_offset is configured by the network through a system message or a dedicated RRC message. Offset is optional and may not be included in the calculation formula.

[0574] Optional embodiment 5: The UE determines the first occasion based on a blind search method, and then determines the positions of other occasions according to the period of the occasion.

[0575] In an embodiment, the UE determines whether the detected PLMN corresponding to the paging robust notification is the PLMN corresponding to the UE, thereby determining whether the occasion corresponding to the paging robust notification is an occasion that needs to be monitored.

[0576] Embodiment: The UE monitors the paging robust notification only on the frequency configured for the UE or on a specific frequency domain location (such as frequency point + bandwidth).

[0577] Embodiment: The UE monitors the paging robust notification only on the synchronization sequence of the paging robust notification configured for the UE.
