Description

Paging method, device and system

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 1, 2024, with application number 202410240955.8 and application name “A Paging Method, Device and System”, the entire contents of which are incorporated by reference into this application.

Technical Field

The present application relates to the field of communication technology, and in particular to a paging method, device, and system.

Background Art

With the development of communication technology, network equipment needs to provide services for larger communication areas to support wider communication service coverage. Non-terrestrial networks (NTNs), for example, offer advantages such as wide coverage, long communication distances, high reliability, flexibility, and high throughput. NTNs are also unaffected by geographical conditions, climate conditions, and natural disasters, and have been widely used in aviation, maritime, and military communications. However, in some scenarios where communication link quality is poor, user equipment (UE) may miss paging messages, resulting in paging failures. This is especially true for paging messages used for public safety or emergency purposes, which can have serious consequences.

Summary of the Invention

The present application provides a paging method, device and system, which can implement paging of UE with poor link quality, while saving unnecessary paging overhead caused by the network equipment's inability to determine the terminal equipment status, and improving the success rate and efficiency of paging terminal equipment.

To achieve the above objectives, this application adopts the following technical solutions:

In a first aspect, the present application provides a paging method. The method can be performed by a first apparatus, which can be a first network device, a component that performs part of the functions of the first network device (such as a centralized unit (CU), a distributed unit (DU), or a radio unit (RU)), or a component within the first network device (such as a chip or chip system). The method may include:

Receive paging assistance information of a terminal device, where the paging assistance information may include one or more of the following: first paging assistance information, second paging assistance information, and third paging assistance information; wherein the first paging assistance information is used to indicate the terminal device's reception performance of receiving a first type of paging message and/or a second type of paging message, the second paging assistance information is used to indicate the terminal device's preference for receiving the first type of paging message and/or the second type of paging message, and the third paging assistance message is used to indicate the terminal device's posture, and the paging performance of the second type of paging message is higher than that of the first type of paging message; when the paging assistance information meets a first preset condition, send a first indication information, where the first indication information is used to instruct the second network device to send a second type of paging message, or, send paging assistance information, or, send paging assistance information and downlink data.

Receive paging assistance information of the terminal device. The paging assistance information can be sent by the terminal device or forwarded through other network devices. The terminal device can support paging through the first type of paging message or the second type of paging message. The terminal device indicates the receiving performance and/or preference of the first type of paging message and/or the second type of paging message, as well as the posture of the terminal device through the first paging assistance information, the second paging assistance information, and the third paging assistance information. It can be understood that the paging assistance information can include one or more of the first paging assistance information, the second paging assistance information, and the third paging assistance information. The paging assistance information can be sent through the same or different signaling. For example The first information may include paging assistance information and other information except the paging assistance information; according to the first paging assistance information and/or the second paging assistance information and/or the third paging assistance information that may be included in the paging assistance information, it is determined that the terminal device can be paged through the second type of paging message, and the terminal device can be paged through the second type of paging message. For example, a first indication information is sent to instruct the second network device to send the second type of paging message, and paging assistance information can also be sent for the second network device to determine to send the second type of paging message according to the paging assistance information. Paging assistance information and downlink data for the terminal device can also be sent to instruct the second network device to send the second type of paging message.

The solution provided in the first aspect above receives the paging assistance information of the terminal device, and according to the indication of the paging assistance information, pages the terminal device through the second type of paging message, and paging the terminal device through the second type of paging message by sending the first indication information, paging assistance information, paging assistance information and downlink data. It can realize paging of the terminal device with poor link quality, and at the same time save unnecessary paging overhead caused by the network equipment's inability to judge the terminal equipment status, thereby improving the success rate and efficiency of paging the terminal device.

As a possible implementation, the first paging assistance information may include one or more of the following: the probability that the terminal device can successfully receive the first type of paging message, the probability that the terminal device can successfully receive the second type of paging message, the probability that the terminal device cannot successfully receive the first type of paging message, and the probability that the terminal device cannot successfully receive the second type of paging message. Based on this, the first paging assistance information of the terminal device can be used to indicate the reception performance of the terminal device in receiving the first type of paging message and/or the second type of paging message. The first paging assistance information of the terminal device may include the probability of successfully receiving the first type of paging message within a preset duration or a certain duration, the probability of successfully receiving the second type of paging message, the probability of not successfully receiving the first type of paging message, and the probability of not successfully receiving the second type of paging message.

Based on this, for the reception performance of the terminal device indicated by the first paging assistance information, when the probability of successfully receiving or failing to successfully receive a paging message (including a first type of paging message and/or a second type of paging message) reaches a preset threshold, a second type of paging message may be sent to the terminal device. When the first paging assistance information meets the above conditions, enhanced paging is performed using the second type of paging message, saving unnecessary paging overhead and improving the success rate and efficiency of paging the terminal device.

As a possible implementation method, the third paging assistance information may also include: the reception performance of the terminal device corresponding to the terminal device when the terminal device is in the posture for receiving the first type of paging message and/or the second type of paging message.

As a possible implementation, the paging assistance information satisfying the first preset condition may include: a probability that the terminal device is in a first preset posture is greater than a fifth threshold value, and the posture may include the first preset posture. Based on this, if the probability of the terminal device being in the first preset posture in the third paging message is greater than the preset threshold, a second type of paging message may be sent to the terminal device. If the third paging assistance information meets the above condition, enhanced paging is performed using the second type of paging message, thereby saving unnecessary paging overhead and improving the success rate and efficiency of paging the terminal device.

As a possible implementation, the first indication information may include identification information of the terminal device. Based on this, the first indication information may instruct the second network device to send a second type of paging message to the terminal device. The second network device may page the terminal device using the second type of paging message based on the identification information of the terminal identifier.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships can exist, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

Hereinafter, the terms "first," "second," and so on are used solely to distinguish different descriptive objects and have no limiting effect on the position, order, priority, quantity, or content of the described objects. For example, if the described object is a "field," the ordinal number preceding the "field" in "first field" and "second field" does not define the position or order of the "fields." "First" and "second" do not define whether the modified "fields" are in the same message, nor do they restrict the order of the "first field" and "second field." For another example, if the described object is a "level," the ordinal number preceding the "level" in "first level" and "second level" does not define the priority of the "levels." For another example, the number of described objects is not limited by the ordinal number and can be one or more. For example, in the case of "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the described object is a "device," the "first device" and "second device" can be the same type of device or different types of devices. For another example, if the described object is "information," the "first information" and "second information" can be information of the same content or different contents. In short, the use of prefixes such as ordinal numbers to distinguish the described objects in the embodiments of the present application does not constitute a restriction on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary restrictions should be constituted due to the use of such prefixes.

Furthermore, in the embodiments of the present application, "connection" may be a direct connection or an indirect connection; in addition, it may refer to an electrical connection or a communication connection; for example, the connection between two electrical components A and B may refer to a direct connection between A and B, or it may refer to an indirect connection between A and B through other electrical components or connection media, or it may refer to an indirect connection between A and B through other communication devices or communication media, as long as communication between A and B can be achieved.

Currently, non-terrestrial networks (NTNs) can use radio frequency (RF) networks or network segments of satellites or unmanned aerial system (UAS) platforms or high-altitude platforms. NTN networks can provide communication services through satellites.

Satellite communications have the advantages of wide coverage, long communication distance, high reliability, great flexibility, and high throughput. They are also unaffected by geographical conditions, climate conditions, and natural disasters, and have been widely used in aviation, maritime, and military communications. In some cases, satellites can be incorporated into fifth-generation mobile networks (5G) to provide communication services in areas difficult to reach by terrestrial networks, such as oceans and forests, thereby enhancing the reliability of 5G communications. For example, they can provide more stable and high-quality communication services for trains, airplanes, and users on these vehicles, and can also provide more data transmission resources and support a greater number of connections.

In satellite communications, the higher the satellite's orbit, the greater its coverage area, but also the correspondingly longer communication latency. Generally speaking, satellite orbits can be categorized by altitude into low Earth orbit (LEO), medium Earth orbit (MEO), and geosynchronous Earth orbit (GEO). For example, non-geosynchronous orbits (NGSO) include low Earth orbits (LEO), with altitudes of approximately 300 to 1,500 kilometers, and medium Earth orbits (MEO), with altitudes of approximately 7,000 to 25,000 kilometers.

In NTN communications, cells can be categorized as fixed cells (or stationary cells), quasi-fixed cells, and mobile cells. A fixed cell refers to a beam, cell, or satellite that covers a fixed geographic area; a quasi-geostationary cell refers to a beam, cell, or satellite that covers a geographic area for a limited time and a different geographic area for another time. In some examples, a quasi-geostationary cell may also be referred to as a quasi-fixed cell. See Figure 1, which shows a schematic diagram of a communication scenario for a quasi-fixed cell. This communication scenario may include a scenario where a non-geosynchronous orbit (NGSO) satellite generates a steerable beam. As shown in Figure 1, satellite 1 covers the same geographic area during the time period T1-T2-T3. A mobile cell refers to a beam, cell, or satellite coverage area that slides across the Earth's surface. See Figure 2, which shows a schematic diagram of a communication scenario for a mobile cell. This communication scenario may include a scenario where an NGSO satellite generates a fixed or non-steerable beam. As shown in Figure 2, satellite 1 covers different geographic areas at T1, T2, and T3, respectively.

In some embodiments, the communication protocol TR38.821 provides the following five NTN-based RAN architectures:

Architecture 1: Transparent Satellite Architecture. Figure 3 shows a schematic diagram of a transparent satellite architecture communication scenario. As shown in Figure 3, the transparent satellite architecture can include UEs, gNBs, core network equipment, and data networks. Satellites and NTN gateways form the remote radio unit between the UE and gNB. The UE and gNB are connected via NR Uu communications, while the gNB and core network, as well as the core network and data network, are connected via NG communications. Satellites can be used for radio frequency filtering, frequency conversion, and amplification. Specifically, the satellite primarily serves as a Layer 1 relay (L1 relay) between the UE and gNB, regenerating physical layer signals and lacking any higher protocol layers.

Architecture 2: Regenerative Satellite Architecture without Intersatellite Links. Figure 4 shows a schematic diagram of a communication scenario for a regenerative satellite without intersatellite links. As shown in Figure 4, this satellite architecture does not include an inter-satellite link (ISL). In this satellite architecture, the UE, core network equipment, and data network, along with the satellite and NTN gateway, form the remote radio unit between the UE and gNB. The UE and satellite are connected via NR Uu communications, while the satellite and core network, as well as the core network and data network, are connected via NG communications. The satellite has base station processing capabilities and can function as a base station between the terminal and core network equipment.

Architecture 3: Regenerative Satellite Architecture with Intersatellite Links. Figure 5 shows a schematic diagram of a communication scenario for a regenerative satellite with an intersatellite link. In this satellite architecture, Satellites 1 and 2 are regenerative satellites with an intersatellite link (ISL). Satellites 1 and 2 are communicatively connected. In this satellite architecture, the UE, core network equipment, and data network, as well as the satellite and NTN gateway, form the remote radio unit between the UE and gNB. The UE and satellite are connected via NR Uu communication, and the satellite and core network, as well as the core network and data network, are connected via NG communication. The satellite has base station processing capabilities and can function as a base station between terminal equipment and core network equipment.

Architecture 4: Architecture of a regenerative satellite with base station DU (disk usage) processing capabilities. Figure 6 shows a schematic diagram of a communication scenario for a regenerative satellite with base station DU processing capabilities. As shown in Figure 6, the satellite architecture can include a UE, gNB, core network equipment, and a data network. The satellite and NTN gateway form the remote radio unit between the UE and gNB. The UE and satellite are connected via NR Uu communication. The satellite and gNB-CU, the gNB-CU and the core network, and the core network and the data network are connected via NG communication. The satellite can function as the base station's DU processing module between the terminal device and the core network equipment.

Architecture 5: Satellite architecture with IAB functionality. In this architecture, satellite can be used as an integrated access and backend (IAB) between terminal devices and core network equipment.

In some embodiments, a terminal device can access a new radio (NR) or other network through an NTN. During the access process, NTN parameter information (also known as NTN-Config or satellite auxiliary information) is required. The NTN parameter information may include one or more of the following: satellite ephemeris information, common timing advance (TA) parameter information, start time (epoch time) parameter information, synchronization validity time (ntn-ulsyncvalidityduration) parameter information, kmac parameter information, DL polarization indication information, UL polarization indication information, TA report enable information, etc.

Satellite ephemeris information can provide satellite ephemeris, which is used to indicate the position of the satellite. The terminal can obtain and/or predict the position of the satellite through the satellite ephemeris; the public timing advance TA parameter information is the public timing advance value controlled by the network. The terminal can obtain the public timing advance TA value through this parameter information. The parameter information can also include the public timing advance value, the public timing advance value drift rate, and the public timing advance value drift rate variation. The terminal can predict and estimate the future and past public timing advance values through this parameter information; the start time parameter information indicates the start time of the NTN parameter information; the synchronization effective time parameter information indicates the N The valid duration of the TN parameter information, during which the terminal can apply the NTN parameter information without obtaining new NTN parameter information; the kmac parameter information refers to the scheduling offset provided by the network when the downlink and uplink frame timings are not aligned on the gNB, and this value can be 0; the DL polarization indication information is used to indicate the polarization mode of the downlink serving link, which can be right-hand circular polarization, left-hand circular polarization, linear polarization, etc.; the UL polarization indication information is used to indicate the polarization mode of the uplink serving link, which can be right-hand circular polarization, left-hand circular polarization, linear polarization, etc.; the TA report enable information is used by the terminal to perform TA reporting during or after random access.

In some embodiments, referring to FIG. 7 , a terminal paging method triggered by a core network device is shown. As shown in FIG. 7 , the method is applicable to idle/inactive UEs. When the core network device triggers paging of the terminal device, the method may include:

S701: The core network device sends a paging message to base station 1 (or base station 2);

In some embodiments, the paging message may include one or more of the following: UE identity (or UE paging identity), paging DRX (discontinuous reception) cycle, TAI (tracking area identity) list, paging priority, paging reason (such as voice), etc.

In some examples, the core network device does not know which base station's coverage area the UE is in, and the core network device may send paging messages to multiple base stations. For example, the base stations may include base station 1, base station 2, and base station 3, and the core network device may send paging messages to base station 1, base station 2, and base station 3.

S702: Base station 1 (or base station 2) sends a paging message for paging the UE according to the paging message received from the core network device;

It should be noted that, when the base station pages the UE according to the information carried in the paging message received from the core network device, the paging message may carry the UE identification information.

In some examples, base station 1 (or base station 2) may be a RAN;

In some embodiments, the UE monitors a paging message from base station 1 (or base station 2), and the UE identifier carried in the paging message matches the UE, then the UE determines that it is being paged.

S703: UE triggers RRC (Radio Resource Control) connection establishment.

In some embodiments, referring to FIG8 , a base station-triggered terminal paging method is shown. As shown in FIG8 , the method is applicable to an inactive UE. When a base station triggers paging of the terminal device or a radio access network (RAN) triggers paging, the method may include:

S801: The core network device sends downlink data to base station 1. The downlink data is downlink data for the UE.

It should be noted that when a base station receives downlink data from an inactive UE, it can buffer the downlink data and trigger a paging message to page the UE. When the NG RAN detects that the downlink data triggering the RAN paging message is related to voice service, it can provide a voice service indication to the UE in the paging message.

S802: Base station 1 sends a paging message for paging UE;

S803: Base station 1 sends a RAN paging message to base station 2;

In some examples, base station 1 cannot determine whether the UE is within its coverage area, and base station 1 can send a RAN paging message to base station 2. The RAN paging message can include one or more of the following: UE RAN paging identity, paging discontinuous reception (DRX) configuration, UE-specific DRX, paging reason (e.g., voice paging), etc.

S804: Base station 2 sends a paging message for paging the UE;

In some embodiments, the UE monitors a paging message from base station 1 (or base station 2), and the UE identifier carried in the paging message matches the UE, then the UE determines that it is being paged.

S805: UE triggers RRC (Radio Resource Control) connection recovery.

However, in some application scenarios, users may place the UE in a backpack or pocket, resulting in poor communication link quality and, in turn, missed paging messages. This is particularly detrimental to paging for public safety or emergency purposes. In some embodiments, a dedicated notification/warning message with enhanced paging performance can be sent. This allows the UE to be received even when it is in a backpack or pocket. The user can then move the UE to a location with better link quality, such as by adjusting the star magnitude. In some examples, the dedicated notification/warning message can be an alert message, which can also be referred to as an enhanced paging message, a dedicated paging message, or a dedicated notification.

In some embodiments, to address the issue of the UE not receiving paging messages due to the user placing it in a pocket or backpack, a paging message can be performed first. If paging fails (or if the UE cannot be paged or does not respond for a long time), an alert paging message can be performed. However, the performance of paging using an alert message or a paging message varies depending on the transmission environment. If a paging message is sent first and then an alert paging message is performed, unnecessary normal paging overhead will be incurred.

Based on this, the present application provides a paging method, device and system, in which the network (base station or core network device) determines whether to send an alert message through the paging assistance information of the UE; the paging assistance information includes first paging assistance information for indicating the receiving performance of the terminal device, second paging assistance information for indicating the paging preference of the terminal device, and third paging assistance information for indicating the posture of the terminal device. In this way, paging of UEs with poor link quality can be achieved, while saving unnecessary paging overhead caused by the network device's inability to judge the terminal device status, thereby improving the success rate and efficiency of paging terminal devices.

In some embodiments, the method provided in this application is applicable to a communication system including a network device and a terminal device. The network device may be a core network device or an access network device (such as a base station). The communication system may also include other devices without limitation.

The user plane gateway can be a server with functions such as mobility management, routing, and forwarding of user plane data, and is generally located on the network side, such as a serving gateway (SGW), a packet data network gateway (PGW), or a user plane function (UPF). The AMF and SMF are equivalent to the mobility management entity (MME) in the long-term evolution (LTE) system. The AMF is mainly responsible for access, and the SMF is mainly responsible for session management. Of course, the core network may also include other network elements, which are not listed here.

The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, and can also implement the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, and can also implement some or all of the physical layer functions. For detailed descriptions of each of these protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be configured separately or included in the same network element, such as the baseband unit (BBU). The RU can be included in a radio frequency device or radio unit, such as a remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH). In different systems, CU, DU or RU may have different names, but those skilled in the art will understand their meanings. For example, in the ORAN system, CU may also be called open CU (open-CU, O-CU), DU may also be called open DU (open-DU, O-DU), and RU may also be called open RU (open-RU, O-RU). Any unit in the CU (or CU control plane (CU control plane, CU-CP), CU user plane (CU user plane, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of software and hardware modules.

The wireless access network device can be a macro base station, a micro base station, an indoor station, a relay node, a donor node, etc. The embodiments of this application do not limit the specific technology and device form used by the wireless access network device. For ease of description, a base station is used as an example of a wireless access network device.

Terminal devices may also be referred to as terminal devices, user equipment (UE), mobile stations, mobile terminal devices, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart cities, etc. Terminal devices can be mobile phones, tablet computers, computers with wireless transceiver functions, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, roadside units (RSUs), sensors, etc. The embodiments of this application do not limit the specific technology and specific device form used by the terminal devices.

The terminal device can establish a connection with the operator network through an interface provided by the operator network (such as N1, etc.) and use data and/or voice services provided by the operator network. The terminal device can also access the domain name system (DNS) through the operator network and use operator services deployed on the DNS and/or services provided by a third party. The third party can be a service provider outside the operator network and the terminal device, and can provide other data and/or voice services to the terminal device. The specific form of the third party can be determined according to the actual application scenario and is not limited here.

In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device functions. The control subsystem that includes the network device functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device functions.

Base stations and terminal devices can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminal devices.

The roles of a base station and a terminal device may be relative, and therefore, both a base station and a terminal device may be collectively referred to as a communication device.

Communication between base stations and terminal devices, between base stations, and between terminal devices can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

In this application, a base station sends downlink signals or downlink information to a terminal device, and the downlink information is carried on a downlink channel; the terminal device sends uplink signals or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal device needs to establish a wireless connection with the cell controlled by the base station. The cell with which the terminal device has established a wireless connection is called the serving cell of the terminal device. When the terminal device communicates with the serving cell, it will also be interfered with by signals from neighboring cells.

The following will describe in detail the communication method provided in the embodiments of the present application with reference to the accompanying drawings.

In some embodiments, referring to FIG9 , which shows a flow chart of a paging method provided in an embodiment of the present application, as shown in FIG9 , the method can be performed by a terminal device, a first network device, and a second network device, or by components or modules in the terminal device, the first network device, and the second network device. The following description uses the device as an example. The method may include:

S901: The terminal device sends paging assistance information, which may include first paging assistance information, second paging assistance information, and third assistance information. Correspondingly, the first network device receives the paging assistance information sent by the terminal device.

In some embodiments, the terminal device sends paging assistance information corresponding to the terminal device, and the paging assistance information may include one or more of the following: first paging assistance information, second paging assistance information, and third paging assistance information; wherein, the first paging message is used to indicate the terminal device's reception performance of receiving the first type of paging message and/or the second type of paging message, the second paging assistance information is used to indicate the terminal device's preference for receiving the first type of paging message and/or the second type of paging message, and the third paging assistance message is used to indicate the terminal device's posture, and the paging performance of the second type of paging message is higher than that of the first type of paging message. Based on this, when the user puts the terminal device in a pocket or backpack, causing the terminal device to fail to receive the first type of paging message, the terminal device can be paged via the second type of paging message. In some examples, the second type of paging message may include an alert message.

In some embodiments, when a terminal device sends paging assistance information of a terminal device, it may be sent directly to the first network device or forwarded through the second network device. Accordingly, the paging assistance information of the terminal device received by the first network device may be sent by the terminal device or forwarded through other network devices. The terminal device may support paging through a first type of paging message or a second type of paging message. The terminal device indicates the reception performance and/or preference for the first type of paging message and/or the second type of paging message, as well as the posture of the terminal device through the first paging assistance information, the second paging assistance information, and the third paging assistance information. It is understood that the paging assistance information may include one or more of the first paging assistance information, the second paging assistance information, and the third paging assistance information. It is understood that the paging assistance information may be sent through the same or different signaling. Exemplarily, the first information may include paging assistance information and other information in addition to the paging assistance information.

In some embodiments, the method may also include: the terminal device receives a first reference signal and a second reference signal, the first reference signal characterizing the signal strength of the first type of paging message received by the terminal device and/or the channel quality for transmitting the first type of paging message, and the second reference signal characterizing the signal strength of the second type of paging message received by the terminal device and/or the channel quality for transmitting the second type of paging signal; wherein the paging performance of the second type of paging message is higher than that of the first type of paging message; based on the first reference signal and the second reference signal, the reception performance of the terminal device for receiving the first type of paging message and/or the second type of paging message is obtained, and first paging auxiliary information is generated.

It should be noted that the terminal device receives the first reference signal and the second reference signal, determines the reception performance of the terminal device for receiving the first type of paging message through the first reference signal, and determines the reception performance of the terminal device for receiving the second type of paging message through the second reference signal. In some examples, the reception performance of the terminal device may include the probability of successfully receiving the first reference signal within a preset duration or a certain duration, the probability of successfully receiving the second reference signal, that is, the proportion of the duration during which the signal strength of the first type of paging message received by the terminal device and/or the channel quality for transmitting the first type of paging message is greater than a preset threshold, and the proportion of the duration during which the signal strength of the second type of paging message received by the terminal device and/or the channel quality for transmitting the second type of paging signal is greater than a preset threshold, and the first paging auxiliary information is generated based on the reception performance of the terminal device for receiving the first type of paging message and/or the second type of paging message.

In some embodiments, the first paging assistance information includes one or more of the following: the probability that the terminal device can successfully receive the first type of paging message, the probability that the terminal device can successfully receive the second type of paging message, the probability that the terminal device cannot successfully receive the first type of paging message, and the probability that the terminal device cannot successfully receive the second type of paging message, and the paging performance of the second type of paging message is higher than that of the first type of paging message.

The first paging assistance information can be used to indicate the reception performance of the terminal device for receiving the first type of paging message and/or the second type of paging message. The first paging assistance information of the terminal device may include the probability of successfully receiving the first type of paging message within a preset time length, the probability of successfully receiving the second type of paging message, the probability of not successfully receiving the first type of paging message, and the probability representation of not successfully receiving the second type of paging message. In some examples, the first paging assistance information may include real-time reporting of whether the terminal device is able to receive the first type of paging message and/or the second type of paging message, and may also include the average value of the terminal device's reception performance within a preset time length. In some examples, the reception performance in the first paging assistance information of the terminal device may include discrete data or continuous data.

In some embodiments, the third paging assistance information includes the posture of the terminal device and/or the probability that the terminal device is in the posture. The third paging assistance information may include the posture of the terminal device, and the posture of the terminal device may characterize the reception performance of the terminal device in receiving the first type of paging message and/or the second type of paging message. In some examples, it may also include the probability that the terminal device is in the posture, and the posture of the terminal device carried by the third paging assistance information may include one or more. In some examples, the third paging assistance information may include a first preset posture, and the first preset posture characterizes that the terminal device can successfully receive the second type of paging message.

In some embodiments, the third paging assistance information further includes: the reception performance of the terminal device corresponding to the terminal device for receiving the first type of paging message and/or the second type of paging message when the terminal device is in the posture. The third paging assistance information may include the reception performance of the terminal device corresponding to the terminal device for receiving the first type of paging message and/or the second type of paging message when the terminal device is in the posture, wherein the posture of the terminal device may represent the reception performance of the terminal device for receiving the first type of paging message and/or the second type of paging message.

In some embodiments, the method further includes: the terminal device generates second paging assistance information based on the reception performance of the terminal device for receiving the first type of paging message and/or the second type of paging message and/or the posture of the terminal device. The terminal device determines the second paging assistance information of the terminal device based on the reception performance of the first type of paging message and/or the second type of paging message and/or the posture of the terminal device. The second paging assistance information may include one or more of the following: the terminal device prefers the first type of paging message, the terminal device does not prefer the first type of paging message, the terminal device prefers the second type of paging message, and the terminal device does not prefer the second type of paging message. In some examples, the second paging assistance information may include that the terminal device supports receiving the second type of paging message.

In some examples, taking the terminal device as a UE, the first network device as a core network device, and the second network device as a base station as an example, refer to FIG10 , which shows a detailed flow diagram of a paging method provided in an embodiment of the present application. As shown in FIG10 , the method may include:

S1001: UE sends alert capability information.

It should be noted that the alert capability information indicates whether the UE supports the alert capability. The alert capability information can be sent directly to the core network device or forwarded to the core network device through base station 1 (or base station 2).

Optionally, S1002: the UE performs measurement and monitoring to generate paging assistance information.

In some embodiments, the UE measures the strength of the normal paging signal (or channel) and the alert signal (or channel), determines the duration ratio or probability of monitoring the normal paging message (i.e., the first type of paging message in the aforementioned embodiment) and the alert message (i.e., the second type of paging message in the aforementioned embodiment) or the UE posture ratio or probability, and generates paging assistance information.

In some examples, the UE can measure a first reference signal or channel related to a normal paging signal (or channel), and the first reference signal strength can reflect the strength of the normal paging signal; the UE can measure a second reference signal or channel related to an alert signal (or channel), and the second reference signal strength can reflect the strength of the alert signal.

In some embodiments, referring to Figure 11, a schematic diagram of a paging scenario type provided in an embodiment of the present application is shown. As shown in Figure 11, when the signal strength is higher than the first strength, the UE can receive a normal paging message; when the signal strength is lower than the first strength but higher than the second strength, the UE can receive an alert message; when the signal strength is lower than the second strength, the UE cannot receive normal paging messages and alert messages and is in an out-of-service state. The UE can determine the proportion or probability of being able to monitor normal paging messages and alert messages based on the signal strength.

In some embodiments, the UE's posture affects whether the UE can receive normal paging messages. The UE can detect its posture and determine the proportion or probability of time the UE is in that posture. Different UE postures correspond to whether the UE can receive normal paging messages and whether it can receive alert messages, and generate paging assistance information.

In some examples, the signal strength when the UE is in a vertical star-pointing state is greater than the signal strength when the UE is in a tilted state, and the signal strength when the UE is in a tilted state is greater than the signal strength when the UE is in a horizontal state. In addition, the signal strength is worst when the UE is in a severely blocked state (for example, placed in a backpack).

In some embodiments, the UE can detect its own posture within a preset time period, record the posture information corresponding to the UE, and at the same time measure the normal paging signal and alert signal strength under the posture, and record whether a normal paging message can be received under the posture; and determine the probability that the UE can receive a normal paging message, the probability that it can receive an alert message (and cannot receive a normal paging message), and the probability that it cannot receive a normal paging message and an alert message within the time period, and generate paging assistance information.

In some embodiments, the UE may determine the paging tendency or paging preference of the UE based on changes in the strength of a normal paging signal (or channel) and an alert signal (or channel), and generate paging assistance information.

S1003: The UE sends paging assistance information, and correspondingly, the core network device receives the paging assistance information sent by the UE.

In some embodiments, the paging assistance information indicates that the UE tends (or prefers) to be paged via an alert message and/or tends to be paged via a normal paging message.

In some embodiments, the paging assistance information may include one or more of the following: a probability that the UE can receive a normal paging message, a probability that the UE can receive an alert message, and a probability that the UE cannot receive a normal paging message and an alert message.

In some embodiments, the paging assistance information may include one or more of the following: probabilities of different UE postures. Different postures may not correspond to whether a normal paging message can be received or whether an alert message can be received. Different postures may indicate whether the UE can receive a normal paging message or an alert message. For example, the probability of the UE being in a posture in which it can receive a normal paging message, a posture in which it can receive an alert message, and a posture in which it cannot receive a normal paging message or an alert message.

In some embodiments, the paging assistance information may include one or more of the following: the probability that the UE can receive a normal paging message, and the corresponding posture information; the probability that the UE can receive an alert message, and the corresponding posture information; the probability that the UE cannot receive a normal paging message and an alert message, and the corresponding posture information.

In the method shown in Figure 9, the method also includes S902: when the paging assistance information meets the first preset condition, the first network device sends a first indication information, and the first indication information is used to instruct the second network device to send a second type of paging message; or, the first network device sends the paging assistance information; or, the first network device sends the paging assistance information and downlink data.

It should be noted that the paging assistance information of the terminal device can be used as a basis for judgment when the first network device needs to page the terminal device. When the first network device does not need to page the terminal device, the paging assistance information of the terminal device can be stored in the first network device; when the first network device needs to page the terminal device, the paging method of the terminal device can be determined based on the paging assistance information.

In some examples, when the first network device receives an instruction to page a terminal device or needs to page the terminal device, the first network device determines the method for paging the terminal device based on the paging assistance information of the terminal device. In this scenario, the paging assistance information is not the reason for the first network device to trigger the paging of the terminal device, but rather the basis for judgment. Therefore, when the first network device needs to page the terminal device and the paging assistance information of the terminal device meets the first preset condition, the first network device sends a second type of paging message, or instructs other network devices to send a second type of paging message. In this way, the paging assistance information can reach the first network device before the first network device has the need to page the terminal device, and will not cause the first network device to trigger the paging of the terminal device. Similarly, in some examples, when the first network device needs to page the UE, it can send the first indication information, paging assistance information, paging assistance information, and downlink data of the terminal device based on the paging assistance information. When the first network device needs to page the terminal device, the first network device can determine the method for paging the terminal device and the signaling to be sent based on the paging assistance information of the terminal device.

In some embodiments, the first paging assistance information received by the first network device may include one or more of the following: the probability that the terminal device can successfully receive the first type of paging message, the probability that the terminal device can successfully receive the second type of paging message, the probability that the terminal device cannot successfully receive the first type of paging message, and the probability that the terminal device cannot successfully receive the second type of paging message.

It should be noted that the first paging assistance information of the terminal device can be used to indicate the reception performance of the terminal device in receiving the first type of paging message and/or the second type of paging message. The first paging assistance information of the terminal device may include the probability of successfully receiving the first type of paging message within a preset time length, the probability of successfully receiving the second type of paging message, the probability of not successfully receiving the first type of paging message, and the probability of not successfully receiving the second type of paging message. In some examples, the first paging assistance information may include real-time reporting of whether the terminal device is able to receive the first type of paging message and/or the second type of paging message, and may also include the average of the terminal device's reception performance within a preset time length. In some examples, the reception performance in the first paging assistance information of the terminal device may include discrete data or continuous data.

In some embodiments, the paging assistance information meeting the first preset condition may include one or more of the following: the probability that the terminal device can successfully receive the first type of paging message is less than the first threshold value, the probability that the terminal device can successfully receive the second type of paging message is greater than the second threshold value, the probability that the terminal device cannot successfully receive the first type of paging message is greater than the third threshold value, and the probability that the terminal device cannot successfully receive the second type of paging message is less than the fourth threshold value.

It should be noted that, for the reception performance of the terminal device indicated by the first paging auxiliary information, when the probability of successfully receiving or failing to successfully receive a paging message (including a first type of paging message and/or a second type of paging message) reaches a preset threshold, a second type of paging message may be sent to the terminal device. In some examples, when the probability of successfully receiving the second type of paging message is within a preset interval, the second type of paging message may be sent to the terminal device.

In some embodiments, the second paging assistance information may include: the terminal device prefers to receive the first type of paging message and/or the terminal device prefers to receive the second type of paging message.
