Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, device, storage medium and program product. Background Art

[0002] The low power wake-up signal (LP-WUS) / low power wake-up receiver (LP-WUR) uses an independent low power receiver to monitor the low power wake-up signal to trigger 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, and can be suitable for delay-sensitive application scenarios.

[0003] To support LP-WUS / WUR in the idle / inactive mode of radio resource control (RRC), it is necessary to consider the LP-WUS process and configuration of LP-WUS triggered paging monitoring, such as the configuration, subgrouping and entry / exit conditions of LP-WUS monitoring. The packet paging method based on LP-WUS can reduce the false wake-up rate and the negative impact of false paging, that is, unnecessary energy consumption of UE caused by paging for another user equipment (UE). However, in some cases, the packet paging method based on LP-WUS may just miss an LP-WUS indication opportunity (that is, the UE will not wake up and listen at the currently associated paging occasion (PO)), and can only listen to PO after waking up the UE with the next low power wake-up signal / mechanism (LO), that is, the packet paging method of LP-WUS causes a delay in receiving the paging message, thereby increasing the delay for the UE to enter the connected state for data transmission.

[0049] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0050] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms such as the third person singular form "comprises" and the present participle form "comprising" are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0051] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0052] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0053] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0054] The design and development of the fifth generation mobile communication technology (5G) system takes into account application scenarios in both mobile communications and vertical fields. In addition to latency, reliability and availability, UE energy efficiency is also key to 5G. Currently, the charging cycle of 5G devices may require weekly or daily, depending on the user's usage time. Typically, the UE consumes tens of milliwatts in the RRC idle / inactive state and hundreds of milliwatts in the RRC connected state. In order to improve energy efficiency and enhance user experience, designs that extend battery life are necessary.

[0055] Energy efficiency is particularly important for UEs that do not have a continuous power source, such as devices using small rechargeable or single button batteries. In vertical applications, sensors and actuators are widely used for monitoring, measurement, and charging. Typically, the batteries of these devices are not rechargeable and are required to last for at least a few years. For wearable devices such as smart watches, rings, health-related devices, and medical monitoring devices, it is challenging to meet the 1-2 week endurance requirement given their standard battery capacity.

[0056] Energy consumption depends on the configuration of the wake-up cycle, such as the paging cycle. In order to meet the above battery life requirements, a longer extended discontinuous reception (eDRX) cycle may be used, but this will result in high latency and is not suitable for services that require both long battery life and low latency. For example, in a fire detection and fire extinguishing scenario, once the sensor detects a fire, the actuator should close the fire door and start the fire sprinkler within 1 to 2 seconds, and the long eDRX cycle cannot meet this latency requirement. Therefore, eDRX is not suitable for delay-sensitive application scenarios.

[0057] Currently, the UE needs to wake up once per DRX cycle, which dominates the power consumption during periods without signaling or data traffic. If the UE wakes up only when triggered (e.g. paging), power consumption can be significantly reduced. This can be achieved by using a wake-up signal to trigger the main radio (MR) and using a separate receiver that can monitor the wake-up signal with ultra-low power consumption. The main radio is used for data transmission and reception and can be turned off or set to deep sleep unless it is turned on. The power consumption of 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.

[0058] To support LP-WUS / WUR in RRC IDLE / INACTIVE mode, it is necessary to consider the LP-WUS process and configuration of LP-WUS triggered paging monitoring, such as the configuration, sub-grouping and entry / exit conditions of LP-WUS monitoring. The packet paging method based on LP-WUS can reduce the false wake-up rate and the negative impact of false paging, that is, the unnecessary energy consumption caused by the UE waking up due to paging for another UE. However, in some cases, it may just miss an LP-WUS indication opportunity (UE will not wake up and listen at the currently associated PO), and can only listen to PO after the next LO wakes up the UE, that is, the packet paging of LP-WUS causes a delay in receiving the paging message; thereby increasing the delay for the UE to enter the connected state for data transmission. When the UE has emergency services such as emergency protocol data unit (PDU) sessions, the delay requirement is relatively high, and it is necessary to page the idle / inactive UE as soon as possible so that the UE can enter the connected state as soon as possible to receive and send emergency services. If the UE still uses the LP-WUS-based packet paging method when it has an emergency service such as an emergency PDU session, there will be a delay, which will affect the processing of emergency services. Therefore, when the terminal has an emergency PDU session, the LP-WUS-based packet paging method should be avoided as much as possible.

[0059] That is to say, in the related art, regardless of whether the terminal has an emergency service, the base station may use the LP-WUS-based packet paging method, and the rationality of the base station using the LP-WUS-based packet paging method is low, resulting in the impact on the processing of emergency services when the terminal has an emergency service. Therefore, how to improve the rationality of using the LP-WUS-based packet paging method is an urgent problem to be solved.

[0060] Based on this, the embodiments of the present disclosure provide a communication method, an apparatus, a storage medium and a program product, wherein a first node sends a 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 group paging based on the usage of the terminal's emergency service, so that the second node decides whether to use the low-power wake-up signal to the terminal for group paging based on the first indication information, that is, so that the second node decides whether to use the LP-WUS-based group paging method based on the first indication information. Compared with the related art, the LP-WUS-based group paging method may be used regardless of whether the terminal has emergency service, the rationality of the second node using the LP-WUS-based group paging method is improved, thereby avoiding the impact of the second node still using the LP-WUS-based group paging method on the processing of the terminal's emergency service when the terminal has emergency service.

[0061] The following describes the solutions of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0062] The technical solution provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, NR mobile communication networks using 5G, future mobile communication networks (such as 6G wireless communication systems) or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0063] Figure 1 FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the communication system includes but is not limited to a terminal 10, a base station 20 and a core network element 30. Among them, the terminal 10, the base station 20 and the core network element 30 can send, receive and interact with each other through wireless signals. Figure 1 The various devices shown may be connected via a wired network or a wireless network, wherein the wired network or the wireless network may include a router, a switch, or other devices that facilitate communication between a plurality of various devices, which is not limited in the embodiments of the present disclosure.

[0064] In some embodiments, the terminal 10 may be a device with wireless transceiver functions, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The embodiments of the present disclosure do not limit the specific type of the terminal 10.

[0065] In some embodiments, the base station 20 may be any of an evolution nodeB (eNB), a next generation nodeB (gNB), a transmission receive point (TRP), a transmission point (TP), a home base station, and some other access nodes. According to the size of the service coverage area provided, the base station can be divided into a macro base station for providing macro cells, a micro base station for providing pico cells, and a femto base station for providing femto cells. With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0066] In some embodiments, the core network element 30 includes at least one of the following:

[0067] Core network, some functions / functional entities of the core network, servers, clients, third-party clients, and application layer.

[0068] As an example, the core network network element 30 includes an access and mobility management function (AMF) network element, a session management function (SMF) network element, a UPF network element, a data analysis function (DAF) network element, a data plane function (DPF) network element, a sensing function (SF) network element, etc.

[0069] It should be understood that Figure 1 is an exemplary structural diagram, Figure 1 The number of devices included in the communication system shown is not limited, for example, the number of terminals 10 and base stations 20 is not limited. Figure 1 In addition to the equipment shown, Figure 1 The communication system shown may also include other devices, which is not limited thereto.

[0070] Next, if Figure 2 As shown, the embodiment of the present disclosure provides a communication method, which is applied to a first node, and the first node is any one of the following: a core network element, a base station, and a terminal. The core network element can be the above Figure 1 The core network element 30 shown in the figure, the base station can be the above Figure 1 The base station 20 shown in the figure, the terminal may be the above Figure 1 In the terminal 10 shown, the method may include the following steps:

[0071] S101: Determine usage of emergency services of a terminal.

[0072] The emergency service may also have other names, such as emergency response service, etc., which is not limited in the embodiments of the present disclosure.

[0073] In some embodiments, the emergency service includes an emergency PDU session, and determining the usage of the emergency service of the terminal may be determining whether the terminal has an emergency PDU session.

[0074] There are two grouping methods based on LP-WUS group paging, one is the grouping method based on the terminal's identifier (the terminal and the base station determine the LP-WUS grouping based on the terminal's identifier), and the other is the grouping method based on the network allocation grouping (AMF allocates LP-WUS grouping to the terminal). When the base station (such as gNB) obtains the LP-WUS grouping identifier allocated by the AMF to the terminal, the LP-WUS grouping identifier allocated by the AMF is used when paging the terminal; otherwise, the base station uses the LP-WUS grouping identifier determined based on the terminal's identifier.

[0075] In the RRC idle state / connection management idle state (CM-idle) state (for example, registration management registered (RM-registered), the core network will still retain some of the terminal's context and PDU session context. When there is downlink data to be sent, paging will be 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.

[0076] When establishing a PDU session for the terminal, the type of PDU session (such as a PDU session for emergency services) will be exchanged between the terminal and the core network element (such as AMF), that is, the terminal and AMF know whether the established PDU session is for emergency services. Then when the terminal has an emergency PDU session, the AMF may not include the LP-WUS group identifier assigned by the AMF to the terminal in the paging message when paging the idle UE. However, the base station does not know whether the terminal has an emergency PDU session, and may continue to use the LP-WUS group identifier determined based on the terminal identifier. When there is an emergency PDU session, in order to ensure the execution of emergency services, it is necessary to avoid / reduce unnecessary paging delays, for example, the base station needs to know whether the terminal has an emergency PDU session or whether the LP-WUS packet paging method is allowed.

[0077] Based on this, during the operation of the first node, the first node determines the usage of the emergency service of the terminal. From the above description, it can be seen that the first node is any one of the following: a core network element, a base station, and a terminal.

[0078] In the case where the first node is a base station, the base station determines the usage of the emergency service of the terminal, which may be that the base station determines the usage of the emergency service of the terminal based on an instruction of a core network element or the terminal.

[0079] S102: Send first indication information to the second node based on usage of the emergency service of the terminal.

[0080] 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. The first indication information can be replaced by the second node deciding whether to use a group paging method based on a low-power wake-up signal.

[0081] In some embodiments, the second node is a base station, which may be the above-mentioned Figure 1 The base station 20 shown. That is, the first indication information is used by the base station to decide whether to send a low power consumption wake-up signal to the terminal for group paging.

[0082] In the case where both the first node and the second node are base stations, the first node may be a base station to which the terminal is connected, and the second node may be a base station in a paging area of ​​a radio access network (RAN) of the terminal. Alternatively, in a new radio-dual connectivity (NR-DC) scenario, the first node is a master node (MN) or a secondary node, and the second node is the other of the MN or the SN, for example, the first node is an MN and the second node is an SN.

[0083] It can be known from the above description that, when the first node is a base station, the base station determines the usage of the terminal's emergency service, which may be the case where the base station determines the usage of the terminal's emergency service based on the indication of the core network element or the terminal. That is, when the base station to which the terminal is connected determines the usage of the terminal's emergency service based on the indication of the core network element or the terminal, the first indication information is sent to the base station in the RAN paging area of ​​the terminal based on the usage of the terminal's emergency service. Alternatively, when one of the MN or the SN determines the usage of the terminal's emergency service based on the indication of the core network element or the terminal, the first indication information is sent to the other of the MN or the SN based on the usage of the terminal's emergency service.

[0084] The base station to which the terminal is connected may be referred to as a source base station, and the base station in the RAN paging area may be referred to as a target base station.

[0085] In some embodiments, when it is determined that an emergency service exists in the terminal, first indication information is sent to the second node.

[0086] As an example, when there is an emergency service on the terminal, the first indication information is used to indicate deactivation / disabling / prohibition of using a packet paging method based on a low-power wake-up signal, or to indicate that there is an emergency service on the terminal.

[0087] In the case where the first node is a core network element, that is, taking the first node as a core network element (SMF / UPF / AMF) sending first indication information to the second node as an example, the first indication information is carried in at least one of the following:

[0088] Next generation (NG) paging messages, network assistance information for inactive terminals (e.g. Core Network Assistance Information for RRCINACTIVE);

[0089] 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 items: a wireless access network paging request message, a switching request message, and an Xn-related message.

[0090] Wherein, when the first node is a base station connected to the terminal and the second node is a base station in the RAN paging area of ​​the terminal, the first indication information is carried in a radio access network paging request message and a handover request message. When the first node is one of the MN and the SN and the second node is the other of the MN and the SN, the first indication information is carried in an Xn-related message.

[0091] In the case where the first node is a terminal, that is, taking the case where the terminal sends the first indication information to the second node as an example, the first indication information is carried in user equipment assistance information (UE assistance information).

[0092] In some embodiments, when the first node is a terminal, the first indication information further includes an identifier of the emergency PDU session. After receiving the first indication information, the second node saves the first indication information in the context of the terminal.

[0093] As another example, the first indication information includes a paging level. Wherein, in the case where the terminal has an emergency service, the paging level is the highest level. The paging level includes a paging priority, and the paging level being the highest level may mean that the paging priority is the highest priority.

[0094] That is, when the terminal has an emergency service (such as an emergency PDU session), the core network element sets the paging priority of the terminal to the highest priority. For example, the paging priority is set to the highest priority in the next generation paging message of the terminal. The paging priority is indicated / introduced in the core network assistance information for RRCINACTIVE for inactive terminals, and when the terminal has an emergency service (such as an emergency PDU session), the AMF sets its value to the highest.

[0095] In some embodiments, the highest level of paging level is used only for emergency services of the terminal.

[0096] As another example, the first indication information is used to indicate that the paging reason is an emergency service.

[0097] If the first indication information includes the paging level or the first indication information is used to indicate that the paging reason is an emergency service, when the first node is a core network element, the first indication information is carried in at least one of the following:

[0098] Next generation paging messages, network assistance information for inactive terminals;

[0099] When the first node is a base station, the first indication information is carried in a radio access network paging message.

[0100] In combination with the above description, when there is an emergency service in the terminal, the first indication information is used to indicate at least one of the following:

[0101] Used to indicate deactivation / disabling / prohibition of the use of the packet paging mode;

[0102] Used to indicate that the terminal has emergency services;

[0103] Used to indicate that the paging reason is emergency business.

[0104] Alternatively, the first indication information includes a paging level, and the paging level is the highest level.

[0105] It should be understood that when the first indication information is used to indicate that the terminal has an emergency service, it represents that the first node uses an explicit method to indicate to the second node that the terminal has an emergency service. When the first indication information is used to indicate the deactivation / disabling / prohibition of the use of the packet paging method based on the low-power wake-up signal, or to indicate that the paging reason is an emergency service, or the first indication information includes a paging level, it represents that the first node uses an implicit method to indicate to the second node that the terminal has an emergency service. The embodiment of the present disclosure does not limit the method used by the first node to indicate to the second node that the terminal has an emergency service.

[0106] The following specific examples illustrate how the first node sends the first indication information to the second node, which may include the following methods.

[0107] Method 1.

[0108] Take 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 cause is an emergency service. When the PDU session is established / modified, for example, in the PDU session resource establishment request / PDU session resource modification request message, it is indicated that the established / modified PDU session is an emergency PDU session, or the RAN paging priority in these messages is set to the highest priority, and the highest priority is only used for emergency PDU sessions. When the AMF initiates core network (CN) paging to an idle terminal, it indicates in the next generation paging message that the terminal has an emergency PDU session, or indicates that the paging cause 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 cause is an emergency service (e.g., paging cause for emergency). Or when the AMF initiates a RAN paging request to the base station, it indicates that the paging cause is an emergency service.

[0109] Method 2.

[0110] Take the first node as a core network element and the second node as a base station as an example. The core network element indicates to the base station (that is, the first indication information) whether the terminal is allowed to use LP-WUS. For example, when the terminal has an emergency PDU session, the AMF indicates in the NG paging message that the LP-WUS packet paging method is allowed / not allowed when paging the terminal; or the AMF indicates in the Core Network Assistance Information for RRC INACTIVE for inactive terminals that the LP-WUS packet paging method is allowed / not allowed.

[0111] Method 3.

[0112] Take the first node as a core network element and the second node as a base station as an example. When the terminal has an emergency PDU session, AMF sets the paging priority of the terminal to the highest priority. For example, the paging priority is set to the highest priority in the NG paging message of the terminal. The paging priority is indicated / introduced in the network assistance information for inactive terminals (Core Network Assistance Information forRRC INACTIVE), and when the terminal has an emergency PDU session, AMF sets its value to the highest.

[0113] Method 4.

[0114] For example, the first node is a terminal and the second node is a base station. When the terminal has an emergency PDU session, the terminal indicates to the base station that there is 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, it is indicated in UE Assistance Information. The base station receives the indication information and saves the indication information in the context of the terminal.

[0115] Method 5.

[0116] Take the first node as a base station and the second node as an example. When the base station decides or receives a paging request indicated by the AMF, it initiates RAN paging to the inactive terminal, determines the RAN paging area, and initiates 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 (that is, the first indication information) that the terminal has an emergency PDU session, or indicate that the paging reason is an emergency service (for example, introducing a new value "emergency" in the paging), or set the paging priority (for example, in the RAN paging message) to the highest priority and the highest priority is only used for emergency services, or indicate whether the LP-WUS packet paging method is allowed / not allowed.

[0117] When a handover occurs to a terminal, if the terminal has an emergency PDU session, the base station may indicate in the Handover Request message (i.e., the first indication information) that the terminal has an emergency PDU session, or indicate the emergency PDU session in the PDU Session Resources To Be Setup List to be established, or introduce a new value "emergency" in the PDU session type. If the target base station does not support the emergency PDU session of the terminal, the target base station may reply with a handover failure message and include a failure reason in the handover failure message, where the failure reason indicates that the emergency PDU session is not supported.

[0118] Under NR-DC, if the terminal has an emergency PDU session, the MN and SN exchange the information that the UE has an emergency PDU session in the Xn related message (i.e., the first indication information). Alternatively, the MN indicates to the SN (i.e., the first indication information) whether to allow / not allow (or enable / disable) the use of the LP-WUS packet paging method.

[0119] based on Figure 2 In the embodiment shown, the first node sends first indication information to the second node for the second node to decide whether to send a low-power wake-up signal to the terminal for group paging based on the usage of the terminal's emergency service, so that the second node decides whether to use the low-power wake-up signal to the terminal for group paging based on the first indication information, that is, so that the second node decides whether to use the LP-WUS-based group paging method based on the first indication information. Compared with the related art that the LP-WUS-based group paging method may be used regardless of whether the terminal has emergency service, the rationality of the second node using the LP-WUS-based group paging method is improved, thereby avoiding the impact of the second node still using the LP-WUS-based group paging method on the processing of the terminal's emergency service when the terminal has emergency service.

[0120] In some embodiments, Figure 3 As shown, the embodiment of the present disclosure further provides a communication method, which is applied to a second node. The method may include the following steps:

[0121] S201. Receive first indication information sent by a first node.

[0122] 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.

[0123] In some embodiments, the first node is any one of the following: a core network element, a base station, or a terminal.

[0124] As an example, when an emergency service exists in the terminal, the first indication information is used to deactivate / disable / prohibit the use of a packet paging method based on a low-power wake-up signal, or to indicate that an emergency service exists in the terminal.

[0125] Wherein, when the first node is a core network element, the first indication information is carried in at least one of the following items:

[0126] Next generation paging messages, network assistance information for inactive terminals;

[0127] When the first node is a base station, the first indication information is carried in at least one of the following:

[0128] Radio access network paging request message, handover request message, Xn related message;

[0129] When the first node is a terminal, the first indication information is carried in user equipment auxiliary information.

[0130] As another example, the first indication information includes a paging level.

[0131] In some embodiments, when there is an emergency service at the terminal, the paging level is the highest level.

[0132] As another example, the first indication information is used to indicate that the paging reason is an emergency service.

[0133] Wherein, when the first indication information includes a paging level, or when the first indication information is used to indicate that the paging reason is an emergency service, further, when the first node is a core network element, the first indication information is carried in at least one of the following items:

[0134] Next generation paging messages, network assistance information for inactive terminals;

[0135] When the first node is a base station, the first indication information is carried in a radio access network paging message.

[0136] In some embodiments, after receiving the first indication information, the second node decides whether to send a low-power wake-up signal to the terminal for group paging based on the first indication information, that is, decides whether to use the group paging method based on the low-power wake-up signal based on the first indication information.

[0137] For example, when the first indication information is used to indicate at least one of the following, the second node decides not to send a low power consumption wake-up signal to the terminal for group paging, and the at least one of the following includes:

[0138] Used to indicate deactivation / disabling / prohibition of the use of the packet paging mode;

[0139] Used to indicate that the terminal has emergency services;

[0140] Used to indicate that the paging reason is emergency business.

[0141] For another example, when 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 group paging. As a possible example, when 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 group paging.

[0142] based on Figure 3In the embodiment shown, 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 group paging, and then decides whether to send a low-power wake-up signal to the terminal for group paging based on the first indication information. That is, the second node decides whether to use the LP-WUS-based group paging method based on the first indication information. Compared with the related art, the LP-WUS-based group paging method may be used regardless of whether the terminal has emergency services. The rationality of the second node using the LP-WUS-based group paging method is improved, thereby avoiding the impact of the second node still using the LP-WUS-based group paging method on the processing of the terminal's emergency services when the terminal has emergency services.

[0143] In some embodiments, the second node (i.e., the base station) uses a centralized unit (CU) and a distributed unit (DU) separation architecture. Under the CU-DU separation architecture, when the CU receives an NG paging message or decides to initiate a RAN paging message or receives a RAN paging message sent by other base stations, the CU sends an F1 paging message to the DU so that the DU pages the terminal.

[0144] Based on this, when there is an emergency service at the terminal, the method may further include at least one of the following:

[0145] The CU sends an F1 paging message and / or paging reason information to the DU, where the F1 paging message and / or paging reason information includes indication information that the terminal has an emergency service;

[0146] The CU sets the paging level of the terminal to the highest level, for example, sets the paging priority of the terminal to the highest priority.

[0147] 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,

[0148] The F1 paging message includes indication information for indicating that the low power consumption wake-up signal is not allowed / disabled.

[0149] That is to say, when the terminal has an emergency PDU session, the CU can indicate in the F1 paging message that the terminal has an emergency PDU session, or indicate emergency services 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.

[0150] When the terminal and the paged cell support LP-WUS packet paging, the CU can indicate the low-power wake-up signal sub-packet support indication to the DU in the F1 paging message, wherein the F1 paging message may include the LP-WUS packet identifier assigned by the CN to the terminal; then when the terminal has an emergency PDU session, the CU does not include the low-power wake-up signal sub-packet support indication in the F1 paging message. Without this indication information, the DU will not use the LP-WUS packet paging method; or the F1 paging message includes LP-WUS not allowed / disabled indication information, and thus the DU will not use the LP-WUS packet paging method.

[0151] In some embodiments, when the terminal has an emergency PDU session, the CU and the DU may perform a UE context establishment / modification process (e.g., a UE context setup / modification request) during the F1 interface, and the CU indicates to the DU that the terminal has an emergency PDU session.

[0152] Combined with the above description of the communication method executed by the second node side, that is, the base station identifies / learns whether the terminal has an emergency PDU session (learned from the core network node / UE indication), and then the base station 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). Then, the base station can send a RAN paging message to other base stations in the RAN paging area to page the terminal, and the RAN paging message indicates whether the terminal has an emergency PDU session / whether to use LP-WUS and other instructions.

[0153] In some embodiments, in order to ensure the uniformity of the behaviors of 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 starts paging the terminal to be paged at the first available paging opportunity, regardless of whether the LP-WUS paging packet is supported and whether the LP-WUS signal has been sent at the LP-WUS opportunity associated with the paging opportunity. In this way, when the terminal has an emergency PDU session, the traditional paging monitoring method can be used (no need to first monitor the LP-WUS packet before waking up to monitor the paging opportunity), and the paging message can be monitored at the earliest paging opportunity.

[0154] In some embodiments, Figure 4 As shown, the embodiment of the present disclosure further provides a communication method, which is applied to a first node. The method may include the following steps:

[0155] S301. Receive second indication information sent by a second node.

[0156] The second indication information is used to instruct the first node to disable monitoring of the low-power wake-up signal when an emergency service exists.

[0157] In some embodiments, the first node comprises a terminal and the second node comprises a base station.

[0158] In some embodiments, the second indication information is carried in system information.

[0159] That is to say, the second node (such as a base station) may include LP-WUS disabling indication information in the system message, and the disabling condition / value is emergency, that is, instructing the terminal to disable LP-WUS monitoring when there is an emergency service (such as an emergency PDU session). Then, after the terminal receives the indication information (that is, the second indication information), it disables LP-WUS monitoring when there is an emergency service.

[0160] Combination Figure 2 The illustrated embodiment can unify the behaviors of the terminal and the base station, thereby avoiding the occurrence of delays.

[0161] In some embodiments, the second indication information is further used to indicate disabling monitoring of the low power consumption wake-up signal when extended discontinuous reception / long extended discontinuous reception (long eDRX) is configured.

[0162] In other words, the coexistence of LP-WUS and long extended discontinuous reception can be considered. In order to better save energy, the terminal can be configured with long extended discontinuous reception with a longer sleep period. However, LP-WUS may require the terminal to wake up frequently to monitor LP-WUS signals or paging messages, which will affect the energy saving effect of long extended discontinuous reception. It is possible to allow / support LP-WUS monitoring when long extended discontinuous reception is configured. The base station may include LP-WUS disabling indication information in the system message, and the disabling condition / value is eDRX, long eDRX, that is, it indicates to disable LP-WUS monitoring when eDRX / long eDRX is configured.

[0163] based on Figure 4 In the embodiment shown, the first node receives second indication information sent by the second node for instructing the first node to disable monitoring of low-power wake-up signals when there is an emergency service, so that the first node disables monitoring of low-power wake-up signals when there is an emergency service, thereby reducing the number of monitoring times of low-power wake-up signals, thereby reducing the energy consumption of the first node (i.e., the terminal).

[0164] In some embodiments, Figure 5 As shown, the embodiment of the present disclosure further provides a communication method, which is applied to a second node. The method may include the following steps:

[0165] S401. Send second indication information to a first node.

[0166] The first node includes a terminal, and the second node includes a base station.

[0167] In some embodiments, in order to ensure the uniformity of the behaviors of the terminal and the base station, when the first node is a terminal, the second node sends second indication information to the first node, and the second indication information is used to instruct the terminal to enable monitoring of low-power wake-up signals when there is an emergency service. After receiving the second indication information, the terminal disables monitoring of low-power wake-up signals when there is an emergency service.

[0168] In some embodiments, the second indication information is carried in the system information, that is, the base station may include the LP-WUS disabling indication information in the system message, and the disabling condition / value is emergency.

[0169] Based on the coexistence problem of LP-WUS and long eDRX, in order to better save energy for the terminal, the second indication information is also used to indicate to enable monitoring of the low power wake-up signal when extended discontinuous reception / long extended discontinuous reception is configured.

[0170] That is, the base station may include LP-WUS disabling indication information in the system message, and the disabling condition / value is eDRX or long eDRX, that is, indicating that LP-WUS monitoring is disabled when eDRX / long eDRX is configured.

[0171] In some embodiments, in combination Figure 2 In order to ensure the uniformity of the behaviors of the terminal and the base station, as shown in the embodiment Figure 6 As shown, the embodiment of the present disclosure further provides a communication method, which is applied to a first node. The method may include the following steps:

[0172] S501: In response to a terminal having an emergency service, perform at least one of the following:

[0173] Stop / exit / disable low power wake-up signal packet paging monitoring mode;

[0174] Ignore entry / exit conditions of low-power wake-up signal monitoring.

[0175] In some embodiments, the first node comprises a terminal.

[0176] That is to say, when it is determined that the terminal has an emergency service (such as an emergency PDU session), the terminal stops / exits / disables the LP-WUS packet paging monitoring method and uses the traditional paging monitoring method. In other words, the entry condition of the LP-WUS monitoring is only valid when the terminal has no emergency service (such as an emergency PDU session); when the terminal has an emergency service (such as an emergency PDU session), the terminal ignores the entry / exit condition of the LP-WUS monitoring.

[0177] based on Figure 6 In the illustrated embodiment, when there is an emergency service at the terminal, executing at least one of the above items can reduce the number of monitoring times of the low-power wake-up signal, thereby reducing the energy consumption of the first node (ie, the terminal).
