Description

A paging method and related equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 5, 2024, application number 202410019108.9, and invention name “A Paging Method and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a paging method and related equipment. Background Art

[0003] The wake-up signal (WUS) is a control signal used to reduce the power consumption of the terminal. In the paging mechanism before Rel-17, the terminal needs to monitor the PDCCH during the paging occasion (PO) and before the PO, and decode the DCI of the PEI or P-RNTI. Therefore, the main receiver (Main Receiver) needs to be woken up before the PO. In Rel-18, the introduction of a receiver with lower power consumption, namely a low power receiver (LR) or WUR, is considered. This type of receiver can receive a simpler WUS (possibly just sequence correlation, without PDCCH decoding), so the power consumption is lower. Therefore, for terminals that are not paged, it is only necessary to start the LR before the PO to detect the WUS. If no WUS is detected, the MR is woken up to monitor the paging.

[0004] However, the above mechanism cannot be applied to idle terminals because the WUS configuration is not saved on the base station. Summary of the Invention

[0005] The present application provides a paging method and related devices for implementing paging of idle terminals based on WUS.

[0006] The first aspect of the present application provides a paging method:

[0007] The first base station sends a target WUS configuration to the terminal, where the target WUS configuration is used by the terminal to detect WUS. The first base station sends the target WUS configuration to the AMF, so that when the AMF pages the terminal, the target WUS configuration is carried in a paging message and sent to one or more second base stations to instruct the one or more second base stations to send WUS to the terminal according to the target WUS configuration.

[0008] In this application, the base station configures the WUS configuration for the terminal in a unicast manner and sends the WUS configuration to the AMF for storage. When the AMF needs to page the terminal, the WUS configuration is carried in the paging message and sent to the base station, so that the base station and the terminal can accurately send and receive WUS based on the WUS configuration.

[0009] In one possible implementation, the first base station receives tendency information reported by the terminal in the connected state, where the tendency information includes WUS tendency information. The first base station determines whether the terminal needs to detect WUS based on the WUS tendency information, and if so, triggers the operation of sending a target WUS configuration to the terminal and sending the target WUS configuration and the terminal identifier to the AMF.

[0010] The WUS tendency information is used to indicate whether the terminal is inclined to detect WUS. Alternatively, the WUS tendency information includes service feature information of the terminal.

[0011] In a possible implementation, the preference information further includes WUS configuration preference information, where the WUS configuration preference information is used to indicate the WUS configuration preferred by the terminal. The first base station determines a target WUS configuration according to the WUS configuration preference information.

[0012] In a possible implementation, the target WUS configuration includes the time difference between the WUS and the PO.

[0013] The second aspect of the present application provides a paging method:

[0014] The AMF receives the target WUS configuration and the terminal identifier sent by the first base station. When the AMF pages the terminal, the AMF determines the target WUS configuration based on the terminal identifier, and the terminal is an idle terminal. The AMF sends a paging message to one or more second base stations, and the paging message includes the target WUS configuration, so that the one or more second base stations send a WUS to the terminal according to the target WUS configuration.

[0015] In one possible implementation, the AMF receives a container and an identifier of the terminal sent by the first base station, where the container includes a target WUS configuration.

[0016] In one possible implementation, the AMF sends a paging message to a second base station, where the second base station is the same base station as the first base station.

[0017] A third aspect of the present application provides a base station, including a sending unit:

[0018] The sending unit is used to send a target WUS configuration to the terminal, where the target WUS configuration is used by the terminal to detect WUS.

[0019] The sending unit is also used to send the target WUS configuration to the AMF, so that when the AMF pages the terminal, the target WUS configuration is carried in the paging message and sent to one or more second base stations to instruct the one or more second base stations to send WUS to the terminal according to the target WUS configuration.

[0020] In a possible implementation, the base station further includes a receiving unit and a processing unit;

[0021] a receiving unit, configured to receive tendency information reported by a terminal in a connected state, the tendency information including WUS tendency information;

[0022] The processing unit is used to determine whether the terminal needs to detect WUS based on the WUS tendency information. If so, it triggers the operation of sending the target WUS configuration to the terminal and sending the target WUS configuration and the terminal identifier to the AMF.

[0023] The WUS tendency information is used to indicate whether the terminal is inclined to detect WUS. Alternatively, the WUS tendency information includes service feature information of the terminal.

[0024] In a possible implementation, the preference information further includes WUS configuration preference information, where the WUS configuration preference information is used to indicate the WUS configuration preferred by the terminal.

[0025] The processing unit is further configured to determine a target WUS configuration according to the WUS configuration tendency information.

[0026] In a possible implementation, the target WUS configuration includes the time difference between the WUS and the PO.

[0027] A fourth aspect of the present application provides an AMF, including a receiving unit, a processing unit, and a sending unit:

[0028] The receiving unit is configured to receive the target WUS configuration and the terminal identifier sent by the first base station.

[0029] The processing unit is configured to determine a target WUS configuration according to an identifier of the terminal when paging the terminal, and the terminal is an idle terminal.

[0030] The sending unit is configured to send a paging message to one or more second base stations, where the paging message includes a target WUS configuration, so that the one or more second base stations send a WUS to the terminal according to the target WUS configuration.

[0031] In one possible implementation,

[0032] The receiving unit is specifically used for the AMF to receive the container and the terminal identifier sent by the first base station, where the container includes the target WUS configuration.

[0033] In one possible implementation,

[0052] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, rather than all the embodiments. Those skilled in the art will appreciate that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0053] The terms "first," "second," and the like in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatus.

[0054] To facilitate understanding of this application, the following first introduces the relevant concepts involved in this application:

[0055] In 4G and 5G cellular communication systems, the network provides services to terminals in cells. After a terminal (UE) selects a cell, it resides in that cell and is ready to initiate uplink services and receive downlink services at any time. From the perspective of the wireless access network, a terminal can have three different service states in a cell:

[0056] Idle state (RRC_IDLE): The UE resides in a cell with no ongoing services and is invisible to the base station and core network. The UE monitors system broadcasts to ensure it has the latest system information. It monitors paging (triggering cell access for uplink services) and initiates random access (active access to the network for uplink services) as needed. The UE also monitors paging messages, which may indicate downlink service triggers, system message changes, or the start of multicast services.

[0057] Connected state (RRC_Connected): The UE responds to network paging or initiates random access, establishes an RRC connection with the base station, and transmits services. The UE is visible to both the base station and the core network.

[0058] Inactive state (RRC_INACTIVE): The UE resides in a cell with no ongoing services. This state is typically configured by the base station when the terminal is released from the connected state. The base station is invisible, but the core network still considers the terminal to be in the connected state. The UE behaves similarly to the idle state, primarily monitoring paging and system messages. The main difference is that paging is primarily RAN paging sent by the base station.

[0059] In cellular systems, regardless of their state, terminals recognize that downlink control information and data sent by the base station can occur at any time, based on a macroscopic time granularity. Therefore, theoretically, UEs within a cell must constantly monitor various control and data channels to ensure they don't miss any downlink control information and data sent by the network. However, the actual time a terminal spends receiving downlink control information and data from the network is relatively short. Therefore, this monitoring logic significantly impacts terminal power consumption, rendering extensive monitoring useless.

[0060] Therefore, for some downlink control information or data, 4G and 5G were designed from the beginning with DRX (Discontinuous Reception, specifically referring to the discontinuous reception of downlink information from the terminal perspective). In the DRX mechanism, the base station and the terminal periodically transmit and receive specific downlink control information or data in an agreed manner, reducing the terminal's monitoring power consumption while meeting downlink latency. The main features include:

[0061] 1. IDLE / INACTIVE DRX, mainly called paging in the protocol. The terminal periodically listens for possible paging messages at a predetermined time and frequency location.

[0062] 2. Connected DRX, mainly referred to as DRX in the protocol. During connected services, the terminal is not required to continuously monitor scheduling information. Instead, it monitors periodically based on the sparseness of services.

[0063] This application mainly involves idle terminals. Please refer to Figure 1. The paging process of idle terminals is introduced below:

[0064] For terminals without services, there is no need to remain in a connected state and occupy the base station's radio resources. In this case, the terminal simply resides in the cell in an idle state, periodically monitoring paging according to the paging process and responding to downlink service requests from the network at any time.

[0065] The UE receives the System Inbound Broadcast (SIB), which contains paging-related configurations (such as the period, other timing information, and frequency domain resource information for paging). Based on the SIB configuration and the paging period, the UE monitors for paging in the corresponding paging occasion (PO) within the corresponding paging frame (PF). In the corresponding PO, the terminal decodes the PDCCH using the P-RNTI and attempts to receive the downlink control information (DCI) containing the paging message scheduling information. If DCI is received, the UE receives the paging message on the PDSCH according to the DCI scheduling information.

[0066] When the core network has downlink traffic, it sends a paging message containing the UE ID to the base station (possibly to multiple base stations. IDLE terminals are invisible to the core network, so the core network will send it to multiple base stations). After receiving the paging message, the base station will determine the UE's PO based on its own system broadcast configuration, using the same method as the UE as specified in the 304 protocol, and send a paging message containing the UE ID to it.

[0067] If a terminal receives a paging message containing its own ID at any time, it considers itself paged and initiates a connection setup (RRCconnectionsetup) to establish a connection with the base station and the core network, enters RRC_CONNECTED, and receives or sends data. After the service is completed, the base station uses the RRCRelease message to release the terminal, and the terminal returns to IDLE.

[0068] Paging is a broadcast signaling sent to the entire cell. At the same time, the calculation of PO only considers the network configuration and UE ID. Therefore, there must be a large number of UEs that theoretically monitor paging messages at the same PO at the same time. However, this method has a flaw, that is, when UE1 on a certain PO is paged, the network will send a PDCCH scrambled by P-RNTI, but all UEs associated with the PO will receive the paging message on the PDSCH. At this time, for UEs other than UE1, the reception and decoding of PDSCH is a meaningless paging false alarm, which will cause unnecessary power waste. Paging early indication (PEI) can solve the above defects. Please refer to Figure 2. The PEI monitoring process is introduced below:

[0069] The PEI (Downlink Control Information) is introduced at a fixed position before the PO. It is also a DCI (Downlink Control Information) sent in the PDCCH. This DCI contains a bitmap of up to 8 bits, with each bit corresponding to a paging packet. Each terminal has its own paging packet. Before monitoring the P-RNTI at the PO, the terminal first monitors the PEI. If the bit corresponding to its own packet in the PEI is 1, it monitors the PO according to the Rel-15 method. Otherwise, it assumes that it will not be paged and returns to sleep mode.

[0070] Rel-18 is under discussion, and Rel-19 will continue to discuss the introduction of Wake up signal / receiver (WUS / WUR) to further reduce the power consumption of paging reception. Please refer to Figure 3. In the paging mechanism before Rel-17, the terminal needs to monitor PDCCH and decode the DCI of PEI or P-RNTI before PO, so it is necessary to wake up the main receiver (Main Receiver) before PO. In Rel-18, consider introducing a receiver with lower power consumption, namely LR (Low power Receiver) or WUR. This type of receiver can receive a simpler WUS (possibly just sequence correlation, without PDCCH decoding), so it consumes less power. Therefore, for terminals that are not paged, it is only necessary to start LR before PO and detect WUS. If no WUS is detected, continue to sleep. If WUS is detected, wake up MR and listen for paging.

[0071] The present application provides a paging method and related devices for implementing paging of idle terminals based on WUS.

[0072] The present application can be applied to the system architecture shown in Figure 4a. When the terminal is in the connected state, a connection is established between the terminal and the base station. At the same time, a connection is established between the base station and the AMF. The AMF is a control plane network function unit whose main responsibilities include registration management, connection management, and mobility management. When the base station releases the terminal to the idle state, the AMF sends a paging message to multiple possible base stations when paging the terminal is needed, so that these multiple base stations page the terminal.

[0073] The first base station in this application is the base station that establishes a connection with the terminal in Figure 4a, and the one or more second base stations are multiple possible base stations in Figure 4a. It should be understood that the one or more second base stations may also include the first base station.

[0074] Please refer to Figure 4b, the process of the paging method of this application is introduced below:

[0075] 401. A first base station sends a target WUS configuration to a terminal, where the target WUS configuration is used by the terminal to detect WUS.

[0076] When a terminal is in a connected state, the base station first determines whether the terminal needs to detect WUS. Optionally, when the terminal is in a connected state, the terminal reports preference information to the connected base station, including WUS preference information. The base station can then determine whether the terminal needs to detect WUS based on the WUS preference information. In one possible scenario, the WUS preference information is used to directly indicate whether the terminal prefers to use WUS paging. Alternatively, the WUS preference information may also include service feature information of the terminal, such as the probability of paging and the service cycle model.

[0077] After receiving the above-mentioned preference information, if the WUS preference information directly indicates whether the terminal prefers to use WUS paging, the base station determines whether the terminal needs to detect WUS based on the indication of the WUS preference information. That is, if the terminal prefers to use WUS paging, the base station determines that the terminal needs to detect WUS. Alternatively, if the WUS preference information includes service feature information of the terminal, the base station independently determines whether the terminal needs to detect WUS based on the service feature information. Of course, if the base station does not receive the above-mentioned preference information, the base station can also independently determine whether the terminal needs to detect WUS.

[0078] If the base station determines that the terminal needs to detect WUS, the base station determines the WUS configuration corresponding to the terminal. The WUS configuration indicates the relevant information of the WUS, which can be used to accurately send and receive WUS between the base station and the terminal, such as time-frequency code resources and grouping information. The base station can determine the WUS configuration of the terminal based on one or more of the terminal's capabilities, service characteristics, and auxiliary information. Optionally, the above-mentioned tendency information may also include WUS configuration tendency information, which indicates the WUS configuration that the terminal tends to, such as the time difference between WUS and PO. The terminal can determine this information based on its own wake-up capability. Correspondingly, the base station can also determine the WUS configuration of the terminal based on this information.

[0079] After the base station determines the WUS configuration of the terminal, it sends the WUS configuration to the terminal. The WUS configuration can be carried in an RRCReconfiguration message or in an RRCConnectionRelease message. Of course, it is not limited to the above two messages. In this embodiment, the base station will eventually release the terminal to the idle state, so it is only necessary to ensure that the WUS configuration is sent to the terminal before releasing the terminal to the idle state.

[0080] 402. The first base station sends a target WUS configuration to the AMF, so that when the AMF pages the terminal, the target WUS configuration is carried in the paging message and sent to one or more second base stations to instruct the one or more second base stations to send WUS to the terminal according to the target WUS configuration.

[0081] The base station will also associate the above-mentioned WUS configuration with the identifier of the above-mentioned terminal (such as S-TMSI) and send it to the AMF together. Specifically, the base station can encapsulate the WUS configuration into a container, associate it with the identifier of the terminal, and send it to the AMF together. After the AMF receives the WUS configuration and the identifier of the terminal, it saves this information locally and establishes an association relationship. When the AMF needs to page the terminal, the AMF finds the corresponding WUS configuration locally based on the identifier of the terminal, and determines multiple base stations in a traditional way, and sends a paging message containing the identifier of the above-mentioned terminal to these multiple base stations, and the paging message includes the above-mentioned WUS configuration. Please refer to Figure 5a. The paging message sent by the AMF to the base station will include a lot of information, and the above-mentioned WUS configuration can be added thereto (not shown in the figure). After multiple base stations receive the paging message, they send WUS to the terminal according to the WUS configuration in the paging message. In one possible implementation, the above-mentioned multiple base stations include the base station to which the terminal accesses in the aforementioned step 401. The AMF only includes the above-mentioned WUS configuration in the paging message sent to the base station, and does not include the above-mentioned WUS configuration in the paging message sent to other base stations among the multiple base stations.

[0082] It should be noted that if in the aforementioned step 401, if the base station determines that the terminal does not need to detect WUS, the base station can send an indication message to the terminal, and the indication message is used to indicate that the terminal does not need to detect WUS. The base station will also encapsulate the indication message into a container, associate it with the terminal identifier, and send it to the AMF. When the AMF needs to page the terminal, it sends a paging message to the above-mentioned multiple possible base stations, and the above-mentioned indication information is included in the paging message. After receiving the paging message, multiple possible base stations determine that there is no need to send WUS based on the indication information, but instead use the traditional method to page the terminal (see the description of Figures 1 and 2).

[0083] In this application, the base station configures the WUS configuration for the terminal in a unicast manner and sends the WUS configuration to the AMF for storage. When the AMF needs to page the terminal, the WUS configuration is carried in the paging message and sent to the base station, so that the base station and the terminal can accurately send and receive WUS based on the WUS configuration.

[0084] Please refer to FIG5b, and another process of the paging method of the present application is introduced below:

[0085] 501. The terminal sends tendency information to the base station in a connected state;

[0086] This step is similar to step 401 in the above embodiment, and the tendency information includes WUS tendency information and WUS configuration tendency information. It should be noted that this step may not be performed.

[0087] 502. The base station sends a WUS configuration to the terminal;

[0088] This step is similar to step 401 described in the aforementioned embodiment. The WUS configuration may be carried in an RRCReconfiguration message or an RRC Connection Release message.

[0089] 503. The base station sends the WUS configuration and the terminal identifier to the AMF.

[0090] This step is similar to step 402 described in the above embodiment and will not be repeated here.

[0091] 504. AMF saves the WUS configuration and the terminal identification;

[0092] This step is similar to step 402 in the aforementioned embodiment and will not be described again here.

[0093] 505. AMF sends a paging message to multiple base stations.

[0094] This step is similar to step 402 in the aforementioned embodiment, and the paging message includes the above WUS configuration.

[0095] 506. The multiple base stations send WUS to the terminal according to the WUS configuration.

[0096] This step is similar to step 402 in the aforementioned embodiment and will not be described again here.

[0097] The above describes the scenario in which the present application is applied to an idle terminal. The present application can also be applied to an inactive terminal. Please refer to FIG5c for a brief description.

[0098] A01. The terminal sends trend information to the base station in the connected state;

[0099] This step is similar to step 401 in the above embodiment, and the tendency information includes WUS tendency information and WUS configuration tendency information. It should be noted that this step may not be performed.

[0100] A02. The base station sends WUS configuration to the terminal;

[0101] This step is similar to step 401 in the above embodiment. The WUS configuration may be carried in an RRCReconfiguration message or an RRCConnectionRelease message. It should be understood that in this embodiment, the base station sending the RRCConnectionRelease message to the terminal will release the terminal to an inactive state.

[0102] A03. The base station sends the WUS configuration and the terminal identifier to the AMF.

[0103] This step is similar to step 402 described in the above embodiment and will not be repeated here.

[0104] A04.AMF saves the WUS configuration and the terminal identification;

[0105] This step is similar to step 402 described in the above embodiment and will not be repeated here.

[0106] A05 and AMF send downlink data and WUS configuration to the base station;

[0107] When the AMF needs to send downlink data to the terminal, it directly sends the downlink data to the base station in the above step, and carries the WUS configuration found locally based on the terminal identifier.

[0108] A06. The base station sends a WUS to the terminal according to the WUS configuration.

[0109] After receiving the downlink data and the WUS configuration, the base station sends the WUS to the terminal based on the WUS configuration, and sends the downlink data to the terminal after restoring the connection with the terminal.
