Description

Communication methods, devices, storage media and software products

[0001] This disclosure claims priority to Chinese patent application No. 202510138515.6, filed on February 7, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a communication method, apparatus, storage medium, and program product. Background Technology

[0003] The low-power wake-up signal (LP-WUS) / low-power wake-up receiver (LP-WUR) uses a separate low-power receiver to monitor the low-power wake-up signal, thereby triggering the main radio to wake up. The main radio is used for data transmission and reception and is only woken up / turned on when triggered. Otherwise, it can be turned off or set to deep sleep, thereby reducing power consumption and being relatively flexible, making it suitable for latency-sensitive applications.

[0004] To support LP-WUS / WUR in Radio Resource Control (RRC) idle / inactive modes, the LP-WUS process and configuration for triggering paging monitoring need to be considered, including LP-WUS monitoring configuration, subgrouping, and entry / exit conditions. LP-WUS-based packet paging can reduce false wake-up rates and mitigate the negative impact of erroneous paging, i.e., unnecessary energy consumption by the UE caused by paging to another user equipment (UE). However, in some cases, LP-WUS-based packet paging may miss an LP-WUS indication opportunity (i.e., the UE will not wake up to listen during the currently associated paging occasion (PO)). It can only listen to the PO after being woken up by the next low-power wake-up signal or mechanism (LO). This means that the delay in receiving paging messages caused by LP-WUS packet paging increases the delay for the UE to enter connected mode for data transmission. Summary of the Invention

[0047] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and other forms such as the third-person singular "comprises" and the present participle "comprising" are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0049] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0050] In this disclosure, the terms "exemplarily" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of the terms "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0052] The design and development of 5G systems takes into account both mobile communication and vertical industry application scenarios. Besides latency, reliability, and availability, UE energy efficiency is also crucial for 5G. Currently, 5G devices may require charging cycles weekly or daily, depending on user usage time. Typically, a UE consumes tens of milliwatts of power in RRC idle / inactive mode and hundreds of milliwatts in RRC connected mode. To improve energy efficiency and enhance user experience, designs that extend battery life are essential.

[0053] Energy efficiency is particularly important for UEs without a continuous power source, such as devices using small rechargeable or single coin cells. In vertical applications, sensors and actuators are widely used for monitoring, measurement, and charging. Typically, the batteries in these devices are non-rechargeable and are required to last for at least several years. Wearable devices such as smartwatches, rings, health-related devices, and medical monitoring devices face challenges in meeting the 1-2 week battery life requirement given their standard battery capacities.

[0054] Power consumption depends on the configuration of the wake-up cycle, such as the paging cycle. To meet the aforementioned battery life requirements, a longer extended discontinuous reception (eDRX) cycle might be used, but this introduces high latency, making it unsuitable for services requiring both long battery life and low latency. For example, in fire detection and extinguishing scenarios, once a sensor detects a fire, the actuator should close the fire door and activate the fire sprinkler head within 1 to 2 seconds, a latency requirement that a long eDRX cycle cannot meet. Therefore, eDRX is not suitable for latency-sensitive applications.

[0055] Currently, the UE needs to wake up once per DRX cycle, which dominates power consumption during periods without signaling or data traffic. Power consumption can be significantly reduced if the UE only wakes up on triggers (e.g., paging). This can be achieved by using a wake-up signal to trigger the main radio (MR) and employing a separate receiver capable of monitoring the wake-up signal with ultra-low power. The MR is used for data transmission and reception and can be turned off or set to deep sleep unless enabled. The power consumption for monitoring the wake-up signal depends on the design of the wake-up signal and the wake-up receiver used for signal detection and processing.

[0056] Supporting LP-WUS / WUR in RRC IDLE / INACTIVE mode requires consideration of the LP-WUS process and configuration for triggering paging monitoring, such as LP-WUS monitoring configuration, sub-groups, and entry / exit conditions. LP-WUS-based packet paging can reduce false wake-up rates and mitigate the negative impact of erroneous paging, i.e., unnecessary energy consumption caused by a UE waking up due to paging of another UE. However, in some cases, an LP-WUS indication opportunity may be missed (the UE will not wake up and listen to the currently associated PO), and it can only listen to the PO after the next LO wakes up the UE. This means that LP-WUS packet paging causes latency in receiving paging messages, further increasing the latency for the UE to enter connected state for data transmission. When a UE has emergency services such as an emergency protocol data unit (PDU) session, latency requirements are high, and it is necessary to page the idle / inactive UE as quickly as possible so that the UE can quickly enter connected state to receive and send emergency services. If LP-WUS-based packet paging is still used when the UE has emergency PDU sessions or other emergency services, latency will occur, affecting the processing of emergency services. Therefore, LP-WUS-based packet paging should be avoided as much as possible when the terminal has emergency PDU sessions.

[0057] In other words, in related technologies, base stations may use LP-WUS-based packet paging regardless of whether the terminal has emergency services. The rationale for base stations to use LP-WUS-based packet paging is low, which can affect the processing of emergency services when they exist. Therefore, improving the rationale for using LP-WUS-based packet paging is an urgent problem to be solved.

[0058] Based on this, embodiments of this disclosure provide a communication method, apparatus, storage medium, and program product. A first node, based on the terminal's emergency service usage, sends first indication information to a second node for the second node to decide whether to send a low-power wake-up signal to the terminal for packet paging. This allows the second node to decide whether to use packet paging by sending a low-power wake-up signal to the terminal, or in other words, to decide whether to use LP-WUS-based packet paging. Compared to related technologies where LP-WUS-based packet paging may be used regardless of whether the terminal has emergency services, this improves the rationality of the second node using LP-WUS-based packet paging, thereby avoiding the impact on the terminal's emergency service processing if the second node still uses LP-WUS-based packet paging when the terminal has emergency services.

[0059] The embodiments of this disclosure will now be described in conjunction with the accompanying drawings.

[0060] The technical solutions provided in this disclosure can be applied to various mobile communication networks, such as 5G NR mobile communication networks, future mobile communication networks (e.g., 6G wireless communication systems), or multiple communication convergence systems, etc. This disclosure does not limit them.

[0061] Figure 1 is a structural diagram of a communication system provided according to an embodiment of the present disclosure. As shown in Figure 1, the communication system includes, but is not limited to, a terminal 10, a base station 20, and a core network element 30. Here, the terminal 10, base station 20, and core network element 30 can transmit and receive wireless signals and perform related interactions. The devices shown in Figure 1 can be connected via a wired network or a wireless network. Here, the wired network or wireless network can include routers, switches, or other devices that facilitate communication between multiple devices; the embodiments of the present disclosure do not limit this.

[0062] In some embodiments, terminal 10 can be a device with wireless transceiver capabilities, such as a mobile phone, tablet computer, wearable device, in-vehicle device, augmented reality (AR) / virtual reality (VR) device, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc. This disclosure does not limit the specific type of terminal 10.

[0063] In some embodiments, base station 20 can be any of the following: evolution node B (eNB), generation node B (gNB), transmission receive point (TRP), transmission point (TP), femtocell, and some other access node. Depending on the size of the service coverage area provided, base stations can be further categorized as macro base stations for providing macrocells, micro base stations for providing picocells, and femto base stations for providing femtocells. As wireless communication technology continues to evolve, future base stations may also adopt other names.

[0064] In some embodiments, the core network element 30 includes at least one of the following:

[0065] Core network, some functions / functional entities of the core network, servers, clients, third-party clients, and application layer.

[0066] As an example, core network element 30 includes access and mobility management function (AMF) network elements, session management function (SMF) network elements, UPF network elements, data analytics function (DAF) network elements, data plane function (DPF) network elements, sensing function (SF) network elements, etc.

[0067] Figure 1 is an exemplary structural diagram. The number of devices included in the communication system shown in Figure 1 is not limited; for example, the number of terminals 10 and base stations 20 is not limited. Furthermore, in addition to the devices shown in Figure 1, the communication system shown in Figure 1 may also include other devices, which are not limited thereto.

[0068] Next, as shown in Figure 2, this embodiment of the disclosure provides a communication method. This method is applied to a first node, which can be any of the following: a core network element, a base station, or a terminal. The core network element can be the core network element 30 shown in Figure 1, the base station can be the base station 20 shown in Figure 1, and the terminal can be the terminal 10 shown in Figure 1. The method can include the following steps:

[0069] S101. Determine the usage status of the terminal's emergency services.

[0070] Here, emergency services may also have other names, such as emergency response services, etc., and this disclosure does not limit this.

[0071] In some embodiments, emergency services include emergency PDU sessions, and determining the usage of emergency services on a terminal can be done by determining whether an emergency PDU session exists on the terminal.

[0072] There are two packet paging methods based on LP-WUS: one is based on the terminal's identifier (the terminal and the base station determine the LP-WUS packet based on the terminal's identifier), and the other is based on network-assigned packets (the AMF assigns LP-WUS packets to the terminal). When the base station (e.g., gNB) obtains the LP-WUS packet identifier assigned to the terminal by the AMF, it uses the AMF-assigned LP-WUS packet identifier when paging the terminal; otherwise, the base station uses the LP-WUS packet identifier determined based on the terminal's identifier.

[0073] In RRC idle state / connection management idle state (CM-idle) (e.g., registration management registered (RM-registered)), the core network still retains part of the terminal's context and PDU session context. When downlink data is transmitted, paging is initiated to trigger the UE to make a service request, such as a network-triggered service request; or when the UE has uplink data, a service request is triggered.

[0074] When establishing a PDU session for a terminal, the terminal and core network elements (such as the AMF) exchange information about the type of PDU session (e.g., a PDU session for emergency services). This means that both the terminal and the AMF know whether the established PDU session is for emergency services. Therefore, when a terminal has an emergency PDU session, the AMF may omit the LP-WUS packet identifier assigned to the terminal in the paging message when paging an idle UE. However, the base station is unaware of whether the terminal has an emergency PDU session and may still use the LP-WUS packet identifier determined based on the terminal's identifier. To ensure the execution of emergency services when an emergency PDU session exists, unnecessary paging delays need to be avoided or reduced. For example, the base station needs to be informed whether the terminal has an emergency PDU session or whether LP-WUS packet paging is permitted.

[0075] Based on this, during the operation of the first node, the first node determines the usage status of the terminal's emergency services. As described above, the first node can be any of the following: core network element, base station, or terminal.

[0076] When the first node is a base station, the base station determines the terminal's emergency service usage status, which can be based on instructions from core network elements or the terminal itself.

[0077] S102. Based on the usage of emergency services on the terminal, send the first instruction information to the second node.

[0078] Here, the first indication information is used by the second node to decide whether to send a low-power wake-up signal to the terminal for packet paging. This can be replaced by the first indication information being used by the second node to decide whether to use a packet paging method based on a low-power wake-up signal.

[0079] In some embodiments, the second node is a base station, which may be the base station 20 shown in Figure 1 above. That is, the first indication information is used by the base station to determine whether to send a low-power wake-up signal to the terminal for packet paging.

[0080] When both the first node and the second node are base stations, the first node can be the base station to which the terminal is connected, and the second node can be a base station in the terminal's radio access network (RAN) paging area. Alternatively, in a new radio-dual connectivity (NR-DC) scenario, the first node is either a master node (MN) or a secondary node, and the second node is either the MN or the SN. For example, the first node is the MN, and the second node is the SN.

[0081] As described above, when the first node is a base station, the base station determines the terminal's emergency service usage status based on indications from core network elements or the terminal itself. Specifically, if the base station connected to the terminal determines the terminal's emergency service usage status based on indications from core network elements or the terminal, it sends a first indication message to the base station in the terminal's RAN paging area. Alternatively, if one of the MNs or SNs determines the terminal's emergency service usage status based on indications from core network elements or the terminal, it sends the first indication message to the other MN or SN.

[0082] Here, the base station to which the terminal is connected can be called the source base station, and the base station in the RAN paging area can be called the target base station.

[0083] In some embodiments, if it is determined that there is an urgent service on the terminal, a first instruction message is sent to the second node.

[0084] As an example, in the event of an emergency service on the terminal, the first indication information is used to indicate the deactivation / de-enablement / disabling of the packet paging method based on low-power wake-up signals, or to indicate that the terminal has an emergency service.

[0085] When the first node is a core network element, that is, when the first node sends the first indication information to the second node as a core network element (SMF / UPF / AMF), the first indication information carries at least one of the following:

[0086] Next generation (NG) paging messages, network assistance information for inactive terminals (e.g., Core Network Assistance Information for RRC INACTIVE in inactive state);

[0087] In the case where the first node is a base station, that is, taking the first node as the base station sending the first indication information to the second node as an example, the first indication information is carried in at least one of the following: radio access network paging request message, handover request message, and Xn related message.

[0088] Here, when the first node is a base station connected to the terminal and the second node is a base station in the terminal's RAN paging area, the first indication information is carried in the radio access network paging request message and the handover request message. When the first node is one of MN or SN and the second node is the other of MN or SN, the first indication information is carried in the Xn related message.

[0089] When the first node is a terminal, that is, taking the terminal sending the first indication information to the second node as an example, the first indication information is carried in the user equipment assistance information.

[0090] In some embodiments, when the first node is a terminal, the first indication information further includes an identifier of an emergency PDU session. After receiving the first indication information, the second node stores the first indication information in the context of the terminal.

[0091] As another example, the first indication information includes the paging level. Here, in the case of an emergency service at the terminal, the paging level is the highest level. The paging level includes the paging priority, and the highest paging level can also mean the highest paging priority.

[0092] In other words, when a terminal has an urgent service (such as an emergency PDU session), the core network element sets the terminal's paging priority to the highest level. For example, the paging priority is set to the highest priority in the terminal's next-generation paging message. The paging priority is indicated / introduced in the Core Network Assistance Information for RRC INACTIVE for inactive terminals, and the AMF sets its value to the highest when the terminal has an urgent service (such as an emergency PDU session).

[0093] In some embodiments, the highest paging level is used only for emergency services of the terminal.

[0094] As another example, the first indication information is used to indicate that the paging reason is an emergency.

[0095] If the first indication information includes a paging level or is used to indicate that the paging reason is an emergency service, and the first indication information is carried in at least one of the following ways when the first node is a core network element:

[0096] Next-generation paging messages; network auxiliary information for inactive terminals;

[0097] When the first node is a base station, the first indication information is carried in the radio access network paging message.

[0098] Based on the above description, in the event of an emergency service on the terminal, the first indication information is used to indicate at least one of the following:

[0099] Used to indicate whether to activate / deactivate / disable the use of packet paging;

[0100] Used to indicate that the terminal has an urgent service;

[0101] Used to indicate that the paging reason is an emergency.

[0102] Alternatively, the first instruction information may include the paging level, which is the highest level.

[0103] When the first indication information indicates that the terminal has an emergency service, it means that the first node is explicitly informing the second node that the terminal has an emergency service. However, when the first indication information indicates that the terminal has an emergency service, or indicates that the paging reason is an emergency service, or includes a paging level, it means that the first node is implicitly informing the second node that the terminal has an emergency service. This embodiment of the present disclosure does not limit the method used by the first node to indicate that the terminal has an emergency service to the second node.

[0104] The following specific examples illustrate how the first node sends the first instruction information to the second node, and may include the following methods.

[0105] Method 1.

[0106] Taking the first node as a core network element and the second node as a base station as an example. The core network element (SMF / UPF / AMF) indicates to the base station (i.e., the first indication information) that the terminal has an emergency PDU session, or indicates that the paging reason is an emergency service. During PDU session establishment / modification, for example, the established / modified PDU session is indicated as an emergency PDU session in the PDU session resource establishment request / PDU session resource modification request message, or the RAN paging priority in these messages is set to the highest priority, which is only used for emergency PDU sessions. When the AMF initiates a core network (CN) paging for an idle terminal, it indicates in the next-generation paging message that the terminal has an emergency PDU session, or indicates that the paging reason is an emergency service (e.g., paging cause for emergency). The AMF indicates that the UE has an emergency PDU session in the Core Network Assistance Information for RRC INACTIVE for inactive terminals, or indicates that the paging reason is an emergency service (e.g., paging cause for emergency). Alternatively, when the AMF initiates a RAN paging request to the base station, it indicates that the paging reason is an emergency service.

[0107] Method 2.

[0108] Taking the first node as a core network element and the second node as a base station as an example, the core network element instructs the base station (i.e., the first instruction information) whether LP-WUS is allowed for the terminal. For example, when the terminal has an emergency PDU session, the AMF indicates in the NG paging message that LP-WUS packet paging is allowed / disallowed when paging the terminal; or the AMF indicates in the Core Network Assistance Information for RRC INACTIVE for inactive terminals that LP-WUS packet paging is allowed / disallowed.

[0109] Method 3.

[0110] Taking a core network element as the first node and a base station as the second node as an example, when a terminal has an emergency PDU session, the AMF sets the terminal's paging priority to the highest. For example, the paging priority is set to the highest priority in the terminal's NG paging message. The paging priority is indicated / introduced in the Core Network Assistance Information for RRC INACTIVE for inactive terminals, and the AMF sets its value to the highest when the terminal has an emergency PDU session.

[0111] Method 4.

[0112] Taking a terminal as the first node and a base station as the second node as an example, when the terminal has an emergency PDU session, the terminal indicates to the base station that it has an emergency PDU session (i.e., the first indication information). In some embodiments, the above indication information may also include a PDU session ID, for example, indicated in the UE Assistance Information. The base station receives the indication information and stores it in the terminal's context.

[0113] Method 5.

[0114] Taking the first node as a base station and the second node as a base station as an example. When the base station decides or receives a paging request indicated by the AMF, it initiates RAN paging for the inactive terminal, determines the RAN paging area, and sends a RAN paging message to the base station in the RAN paging area. When the terminal has an emergency PDU session, the base station needs to indicate in the RAN paging message (i.e., the first indication information) that the terminal has an emergency PDU session, or indicate that the paging reason is an emergency service (e.g., introducing a new value "emergency" in the paging), or set the paging priority (e.g., in the RAN paging message) to the highest priority and that the highest priority is only used for emergency services, or indicate that LP-WUS packet paging is allowed / disallowed.

[0115] When a terminal handover occurs, if the terminal has an emergency PDU session, the base station can indicate the emergency PDU session in the Handover Request message (i.e., the first indication information), or in the PDU Session Resources To Be Setup List, or introduce a new value "emergency" in the PDU session type. If the target base station does not support the terminal's emergency PDU session, the target base station can reply with a handover failure message, including the reason for the failure, indicating that the emergency PDU session is not supported.

[0116] Under NR-DC, if the terminal has an emergency PDU session, the MN and SN communicate in the Xn related message (i.e., the first indication information) that the UE has an emergency PDU session. Alternatively, the MN instructs the SN (i.e., the first indication information) to allow / disallow (or enable / disable) the use of LP-WUS packet paging mode.

[0117] Based on the embodiment shown in Figure 2, the first node sends a first indication message to the second node based on the terminal's emergency service usage. This first indication message allows the second node to decide whether to send a low-power wake-up signal to the terminal for packet paging. In other words, it allows the second node to decide whether to use LP-WUS-based packet paging. Compared to related technologies where LP-WUS-based packet paging may be used regardless of whether the terminal has emergency services, this improves the rationality of the second node using LP-WUS-based packet paging. This avoids the impact on the terminal's emergency service processing caused by the second node still using LP-WUS-based packet paging even when the terminal has emergency services.

[0118] In some embodiments, as shown in FIG3, this disclosure also provides a communication method applied to a second node, the method comprising the following steps:

[0119] S201, Receive the first instruction information sent by the first node.

[0120] Here, the first indication information is used by the second node to decide whether to send a low-power wake-up signal to the terminal for group paging.

[0121] In some embodiments, the first node is any one of the following: a core network element, a base station, or a terminal.

[0122] As an example, in the event of an emergency service on the terminal, the first indication information is used to deactivate / disable / disable the use of packet paging based on low-power wake-up signals, or to indicate that the terminal has an emergency service.

[0123] Here, when the first node is a core network element, the first indication information is carried in at least one of the following:

[0124] Next-generation paging messages; network auxiliary information for inactive terminals;

[0125] When the first node is a base station, the first indication information is carried in at least one of the following:

[0126] Radio access network paging request messages, handover request messages, and Xn-related messages;

[0127] When the first node is a terminal, the first indication information is carried in the user equipment auxiliary information.

[0128] As another example, the first indication information includes the paging level.

[0129] In some embodiments, the paging level is the highest level when there is an emergency service on the terminal.

[0130] As another example, the first indication information is used to indicate that the paging reason is an emergency.

[0131] Here, where the first indication information includes a paging level, or where the first indication information is used to indicate that the paging reason is an emergency service, and further, where the first node is a core network element, the first indication information is carried in at least one of the following:

[0132] Next-generation paging messages; network auxiliary information for inactive terminals;

[0133] When the first node is a base station, the first indication information is carried in the radio access network paging message.

[0134] In some embodiments, after receiving the first indication information, the second node decides, based on the first indication information, whether to send a low-power wake-up signal to the terminal for packet paging. That is, it decides whether to use a packet paging method based on a low-power wake-up signal based on the first indication information.

[0135] For example, if the first indication information indicates at least one of the following, the second node decides not to send a low-power wake-up signal to the terminal for packet paging, where at least one includes:

[0136] Used to indicate whether to activate / deactivate / disable the use of packet paging;

[0137] Used to indicate that the terminal has an urgent service;

[0138] Used to indicate that the paging reason is an emergency.

[0139] For example, if the first indication information includes a paging level, the second node decides not to send a low-power wake-up signal to the terminal for packet paging. In some embodiments, if the first indication information includes a paging level, and the paging level is the highest level, the second node decides not to send a low-power wake-up signal to the terminal for packet paging.

[0140] Based on the embodiment shown in Figure 3, the second node receives first indication information sent by the first node for the second node to decide whether to send a low-power wake-up signal to the terminal for packet paging. Then, based on the first indication information, the second node decides whether to send a low-power wake-up signal to the terminal for packet paging. That is, the second node decides whether to use the LP-WUS-based packet paging method based on the first indication information. Compared with related technologies, which may use the LP-WUS-based packet paging method regardless of whether the terminal has emergency services, this improves the rationality of the second node using the LP-WUS-based packet paging method, thereby avoiding the impact on the terminal's emergency service processing when the second node still uses the LP-WUS-based packet paging method when the terminal has emergency services.

[0141] In some embodiments, the second node (i.e., the base station) uses a separate architecture for the centralized unit (CU) and the distributed unit (DU). In this CU-DU separation architecture, when the CU receives an NG paging message, decides to initiate a RAN paging message, or receives a RAN paging message from another base station, the CU sends an F1 paging message to the DU, thereby enabling the DU to paging the terminal.

[0142] Based on this, in the event of an emergency service on the terminal, the method may further include at least one of the following:

[0143] The CU sends an F1 paging message and / or paging reason information to the DU. The F1 paging message and / or paging reason information contains an indication that the terminal has an emergency service.

[0144] The CU sets the terminal's paging level to the highest level, for example, setting the terminal's paging priority to the highest priority.

[0145] In some embodiments, the F1 paging message does not include a Low Power Wake-up Signal Subgrouping Support Indication (LP-WUS subgrouping support indication), or,

[0146] The F1 paging message includes indication information to indicate that the low-power wake-up signal is not allowed / de-enabled.

[0147] In other words, when a terminal has an emergency PDU session, the CU can indicate that the terminal has an emergency PDU session in the F1 paging message, or indicate an emergency service in the paging reason (for example, the paging reason introduces a new value "emergency"), or set the paging priority to the highest priority and the highest priority is only used for emergency services.

[0148] When the terminal and the cell being paged support LP-WUS packet paging, the CU can indicate a Low Power Wake-up Signal Subpacket Support Indication to the DU in the F1 paging message. Here, the F1 paging message may contain the LP-WUS packet identifier assigned to the terminal by the CN. However, when the terminal has an emergency PDU session, the CU will not include a Low Power Wake-up Signal Subpacket Support Indication in the F1 paging message. Without this indication, the DU will not use the LP-WUS packet paging method. Alternatively, the F1 paging message may contain an indication that LP-WUS is not allowed / disabled, and thus the DU will not use the LP-WUS packet paging method.

[0149] In some embodiments, when the terminal has an emergency PDU session, the CU and DU can, during the UE context setup / modification process on the F1 interface (e.g., UE context setup / modification request), indicate to the DU that the terminal has an emergency PDU session.

[0150] Based on the above description of the communication method executed on the second node side, that is, the base station identifies / knows whether the terminal has an emergency PDU session (obtained from the core network node / UE indication), and then determines the paging method used when paging the terminal; (when the UE has an emergency PDU session, the LP-WUS packet paging method is not used). Furthermore, the base station can send RAN paging messages to other base stations within the RAN paging area to page the terminal. The RAN paging message indicates whether the terminal has an emergency PDU session / whether LP-WUS is used, etc.

[0151] In some embodiments, to ensure consistency in behavior between the terminal and the base station, when the second node receives a CN paging message or a RAN paging message, or decides to initiate a RAN paging message, it always begins paging the terminal to be paging at the first available paging opportunity, regardless of whether LP-WUS paging packets are supported or whether an LP-WUS signal has already been sent at the LP-WUS opportunity associated with that paging opportunity. In this way, when the terminal has an emergency PDU session, the traditional paging monitoring method can be used (without needing to first detect the LP-WUS packet before waking up to monitor the paging opportunity), allowing the paging message to be detected at the earliest paging opportunity.

[0152] In some embodiments, as shown in FIG4, this disclosure also provides a communication method applied to a first node, the method including the following steps:

[0153] S301, Receive the second instruction information sent by the second node.

[0154] Here, the second instruction information is used to instruct the first node to enable the listening of low-power wake-up signals in the event of an emergency service.

[0155] In some embodiments, the first node includes a terminal and the second node includes a base station.

[0156] In some embodiments, the second indication information is carried in system information.

[0157] In other words, the second node (e.g., the base station) can include LP-WUS de-enablement indication information in the system message. The de-enablement condition / value is "emergency", which means that the terminal is instructed to enable LP-WUS listening when there is an emergency service (e.g., an emergency PDU session). After receiving this indication information (i.e., the second indication information), the terminal will enable LP-WUS listening when there is an emergency service.

[0158] By combining the embodiment shown in Figure 2, the behavior of the terminal and the base station can be unified, thereby avoiding the occurrence of time delays.

[0159] In some embodiments, the second indication information is also used to indicate whether to enable listening to the low-power wake-up signal when configured with Extended Discontinuous Reception / Long Extended Discontinuous Reception (long eDRX).

[0160] In other words, the coexistence of LP-WUS and long extended discontinuous reception can be considered. For better energy saving, long extended discontinuous reception can be configured for the terminal, which has a longer sleep period. However, LP-WUS may require the terminal to frequently wake up to listen for LP-WUS signals or paging messages, which will affect the energy-saving effect of long extended discontinuous reception. Whether LP-WUS listening is allowed / supported can be determined when long extended discontinuous reception is configured. The base station can include LP-WUS de-enabling indication information in the system message, with the de-enabling condition / value being eDRX or long eDRX, indicating that LP-WUS listening is enabled when eDRX / long eDRX is configured.

[0161] Based on the embodiment shown in Figure 4, the first node receives a second instruction message sent by the second node, which instructs the first node to enable the listening of low-power wake-up signals in the event of an emergency service. This enables the first node to enable the listening of low-power wake-up signals in the event of an emergency service, reducing the number of times the low-power wake-up signals are listened to, thereby reducing the energy consumption of the first node (i.e., the terminal).

[0162] In some embodiments, as shown in FIG5, this disclosure also provides a communication method applied to a second node, the method including the following steps:

[0163] S401, Send the second instruction information to the first node.

[0164] Here, the first node includes the terminal, and the second node includes the base station.

[0165] In some embodiments, to ensure consistency in behavior between the terminal and the base station, when the first node is the terminal, the second node sends a second indication message to the first node. This second indication message instructs the terminal to enable low-power wake-up signal monitoring in the event of an emergency service. Upon receiving this second indication message, the terminal enables low-power wake-up signal monitoring in the event of an emergency service.

[0166] In some embodiments, the second indication information is carried in the system information. That is, the base station may include LP-WUS disable indication information in the system message, and the condition / value for disabling it is "emergency".

[0167] To address the issue of LP-WUS and long eDRX coexistence and to improve terminal energy efficiency, the second indication information is also used to indicate whether to enable low-power wake-up signal monitoring when configured with extended discontinuous reception / long extended discontinuous reception.

[0168] In other words, the base station can include LP-WUS de-enabling indication information in the system message, with the de-enabling condition / value being eDRX or long eDRX, which indicates that LP-WUS monitoring is de-enabled when eDRX / long eDRX is configured.

[0169] In some embodiments, in conjunction with the embodiment shown in FIG2, in order to ensure the uniformity of behavior between the terminal and the base station, as shown in FIG6, this disclosure also provides a communication method applied to a first node, which may include the following steps:

[0170] S501. In response to an emergency service being detected on the terminal, perform at least one of the following:

[0171] Stop / exit / de-enable low-power wake-up signal group paging monitoring mode;

[0172] Ignore the entry / exit conditions for low-power wake-up signal listening.

[0173] In some embodiments, the first node includes a terminal.

[0174] In other words, when it is determined that the terminal has an urgent service (such as an urgent PDU session), the terminal stops / exits / disables the use of LP-WUS packet paging monitoring mode and instead uses the traditional paging monitoring mode. Or, to put it another way, the entry conditions for LP-WUS monitoring are only valid when the terminal does not have an urgent service (such as an urgent PDU session); when the terminal has an urgent service (such as an urgent PDU session), the terminal ignores the entry / exit conditions for LP-WUS monitoring.

[0175] Based on the embodiment shown in Figure 6, when there is an emergency service on the terminal, performing at least one of the above-mentioned actions can reduce the number of times the low-power wake-up signal is listened to, thereby reducing the energy consumption of the first node (i.e., the terminal).
