Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method for determining a paging mode and a terminal device. Background Art

[0002] In a cellular communication system, terminal devices in the idle state and the inactive state periodically listen for paging, so as to initiate processes such as RRC connection establishment or RRC connection recovery in response to a paging message.

[0003] To avoid the power consumption caused by the terminal device continuously listening for paging, currently, based on the traditional paging mode, the PEI (paging early indication) technology is introduced. Among them, PEI can group the terminal devices associated with a paging occasion, and then perform paging indication for each group of terminal devices respectively. In addition, currently, the WUS (wake up signal) technology is also introduced to further reduce the power consumption of the terminal device.

[0004] On the premise that there are multiple paging modes, if the network device and the terminal device do not use the same paging mode, paging anomalies may occur. Summary of the Invention

[0005] An embodiment of this application provides a method for determining a paging mode and a terminal device, which are applied to the field of communication technologies. The technical solution of this application can enable the network device and the terminal device to send and receive paging in the same process, so that the network device can send a paging message to a specific terminal device in an accurate paging mode, and save network paging resources on the premise of avoiding paging loss.

[0006] In a first aspect, an embodiment of this application proposes a method for determining a paging mode, which is applied to a terminal device. The method includes:

[0007] Receiving first indication information sent by a network device, where the first indication information is used to indicate a first paging mode supported by the network device;

[0008] Determining a target paging mode for receiving a paging message according to the first paging mode and a second paging mode corresponding to the terminal device.

[0009] In this implementation manner, the terminal device and the network device align the first paging manner and the second paging manner, and then the terminal device and the network device determine the target paging manner based on the same manner. Therefore, it can be ensured that the network device and the terminal device implement the transmission of paging messages based on the same target paging manner, so that the terminal device can correctly receive the paging, and when the target paging manner has the effect of power saving, it can also be ensured that the power saving effect can be normally exerted.

[0010] In a possible implementation manner, the second paging manner is a paging manner supported by the terminal device, and the method further includes:

[0011] Sending second indication information to the network device, where the second indication information is used to indicate the second paging manner.

[0012] In this implementation manner, the terminal device sends the second indication information to the network device, which can simply and effectively implement the terminal device reporting the second paging manner it supports.

[0013] In a possible implementation manner, the second paging manner is a paging manner negotiated between the terminal device and the core network device, and the method further includes:

[0014] Sending third indication information to the core network device, where the third indication information is used to indicate a third paging manner supported by the terminal device; and,

[0015] Receiving first configuration information sent by the core network device, where the first configuration information is used to indicate the second paging manner, and where the second paging manner is determined by the core network device from the third paging manner.

[0016] In this implementation manner, the terminal device directly negotiates the second paging manner with the core network device, thereby saving certain signaling overhead. At the same time, the terminal device and the core network negotiating the second paging manner can also improve the adaptability of the determined second paging manner to the current network situation.

Among them, 5G refers to the fifth-generation mobile communication technology (5th Generation Mobile Communication Technology), abbreviated as 5G.

[0126] 2. Network device

[0127] A network device can be a device for communicating with a terminal device. For example, it can be a Base Transceiver Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication system, or a NodeB (NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an Evolutional Node B (eNB or eNodeB) in an LTE system. Alternatively, the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, or a network-side device in a future 5G network or a network after 5G, or a network device in a future evolved Public Land Mobile Network (PLMN).

[0128] The network device involved in the embodiments of this application can also be referred to as a network device or a Radio Access Network (RAN) device. The RAN device is connected to the terminal device and is used to receive data from the terminal device and send it to the core network device. The RAN device corresponds to different devices in different communication systems. For example, in a 2G system, it corresponds to a base station and a base station controller; in a 3G system, it corresponds to a base station and a Radio Network Controller (RNC); in a 4G system, it corresponds to an Evolutional Node B (eNB); in a 5G system, it corresponds to the 5G system, such as the access network devices (e.g., gNB, Central Unit CU, Distributed Unit DU) in New Radio (NR).

[0129] 3. Core network device

[0130] The core network device can be, but is not limited to, a mobile management entity (MME) / serving gate way (SGW), MME, etc., where MME / SGW means that the MME and the SGW are located in one physical entity.

[0131] 4. Network elements in the core network

[0132] In the 5G core network (5G core / new generation core, 5GC / NGC), there are multiple functional units, including the Access and Mobility Management Function (AMF) network element, Session Management Function (SMF) network element, User Plane Function (UPF) network element, Authentication Server Function (AUSF) network element, Policy Control Function (PCF) network element, Application Function (AF) network element, unified data management (UDM) network element, Network Slice Selection Function (NSSF) network element, etc.

[0133] Among them, the AMF network element is mainly responsible for services such as mobility management and access management. Exemplarily, the terminal device can transmit control plane messages to the AMF network element through the NG interface 1 (abbreviated as N1).

[0134] 5. RRC Status

[0138] 7. NAS Signaling

[0139] The NAS (Non-Access Stratum) protocol refers to the communication protocol between the terminal device and the core network device. Correspondingly, the NAS signaling is the signaling used for interaction between the network device and the core network device.

[0140] 8. Other Terms

[0141] In the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and effects. For example, the first chip and the second chip are only used to distinguish different chips, and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and "first", "second", etc. do not necessarily mean different.

[0142] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0143] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (s) or multiple items (s). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.

[0144] To better understand the technical solution of the present application, on the basis of the above-introduced concepts, the related technologies involved in the present application will be further introduced in detail below.

[0145] Energy conservation and emission reduction is a topic that the world is currently concerned about. To achieve the purpose of energy conservation and emission reduction, it is usually required that the device reduces power consumption as much as possible without affecting the business.

[0146] For example, to achieve the purpose of energy conservation and emission reduction, in the current communication system, when the terminal device does not need to communicate with the network device, the terminal device can release the RRC connection, thereby entering the RRC idle state or the RRC inactive state, so that the terminal device can save electric energy and reduce power consumption.

[0147] Among them, after the RRC connection between the terminal device and the network device is released, the core network device can, for example, mark the terminal device as entering the idle state or the inactive state. When it is necessary to send downlink data to the terminal device in the idle state or the inactive state, the core network device first sends a paging message to all network devices in the tracking area where the terminal device is located, so that the paging message can be forwarded to the terminal device through the network device. Among them, the tracking area includes multiple cells where the terminal device can move freely, and the multiple cells belong to at least one network device.

[0148] Correspondingly, the terminal device in the idle state or the inactive state needs to periodically monitor the paging message, and then respond to the paging message to initiate an RRC connection procedure or an RRC resume procedure to the network device in order to perform downlink services. Specifically, when the terminal device enters the working state in response to the paging message, it means that the terminal device is awakened. Specifically, the transceiver in the terminal device is awakened so that the terminal device can communicate with the network device subsequently.

[0149] For example, based on the above-introduced content, Figure 1 the communication system in this application will be introduced. Figure 1 It is the system architecture diagram of the communication system provided by the embodiment of this application.

[0150] As Figure 1 shown, the architecture of the communication system includes: multiple network devices, multiple terminal devices, and a core network device.

[0151] Among them, the terminal device is used to access the network device to perform various services (such as voice services, short message services, Internet services, etc.). For example, Figure 1 the terminal device 1 in can access the network device 1 to perform various services; the terminal device 2 can access the network device 1 or access the network device 2 to perform various services, and the terminal device 3 can access the network device 2 to perform various services.

[0152] In addition, each terminal device can move freely within the network coverage area. When the terminal device is in the idle state or the inactive state, the free movement area of the serving network device does not need to be updated to the tracking area (TA) of the terminal device. The TA includes multiple cells where the terminal device can move freely, and the multiple cells are the areas covered by at least one network device. The TA of the terminal device can change, that is, the terminal device can have different tracking areas at different times or locations. The terminal device needs to register or update the TA with the core network device so that the core network device can identify the TA where the terminal device is located in the idle state or the inactive state, and then can accurately page the terminal device when it is necessary to send downlink data to the terminal device.

[0153] Among them, the network device is located in the access network and is used to provide wireless access services for terminal devices, so that the terminal devices can access the corresponding network devices for various services. Among them, each network device can provide wireless access services for at least one terminal device. For example, Figure 1 the network device 1 shown in

[0154] can provide wireless access services for terminal device 1 and terminal device 2, and network device 2 can provide wireless access services for terminal device 2 and terminal device 3.

[0155] In specific implementation, when any terminal device accesses a network device, that is, when the terminal device communicates with the network device, an RRC connection will be established between the two. When communication is no longer required between the terminal device and the network device, the RRC connection can be released.

[0156] After the RRC connection is released, the terminal device will enter the idle state or the inactive state. When the core network device needs to page the terminal device, the core network device may send a paging message to each network device in the TA where the terminal device is located, so as to page the terminal device. For example, in Figure 1 the example of

[0157] assuming that the TA corresponding to terminal device 1 includes network device 1 and network device 2, the core network device can send paging messages to core network device 1 and core network device 2 at the same time, and then network device 1 and network device 2 send paging messages to terminal device 1, so as to accurately page the terminal device. Figure 1 After that, the terminal device responds to the paging message and establishes an RRC connection with the network device, and then it can receive downlink data. And it should also be noted that although not shown,

[0158] in the architecture of the communication system shown in

[0159] There may also be other devices or network elements. Figures 2 to 5 After introducing the system architecture of terminal devices, network devices, and core network devices, let's talk about the mechanism of periodic paging monitoring of terminal devices. Among them, one of the goals of the terminal device's periodic paging monitoring itself is to avoid the terminal continuously monitoring downlink data, thereby saving the power of the terminal device. Despite this periodic paging monitoring mechanism, research on optimization schemes for paging is still ongoing to further reduce the terminal energy consumption during the paging process.

[0160] The first type: Paging method of decoding PDCCH in PO periodically

[0161] This paging method can also be called a paging method of directly decoding PDCCH in PO periodically, which can be understood as a traditional paging method, or the basic mechanism of paging. First of all, it should be noted that the terminal device in the RRC idle state or RRC inactive state is mainly in the sleep state, and the main receiver (MR) of the terminal device in the sleep state is turned off.

[0162] As Figure 2 shown, in the paging method introduced currently, the terminal device in the RRC idle state or RRC inactive state can wake up in its associated PO (paging occasion), for example, the terminal device can wake up the main receiver, so as to listen for paging through the main receiver in the PO.

[0163] Among them, each terminal device has its own associated PO. The calculation of the PO associated with the terminal device is related to parameters such as the ID (identifier) of the terminal device and the paging cycle, so multiple terminal devices can share one PO.

[0164] Referring to Figure 2 it can be determined that the PO associated with the terminal device repeats with the paging cycle, so the terminal device can implement periodic paging listening. Among them, the terminal device can execute the operations introduced in this embodiment in the PO in each of its corresponding paging cycles. Therefore, only the implementation within one paging cycle is taken as an example for introduction in this embodiment.

[0165] When the terminal device listens for paging in the PO, the terminal device can first use P-RNTI (Paging Radio Network Temporary Identifier) to decode the PDCCH, for example.

[0166] When the core network device needs to page the terminal device, it will instruct the network device to send PDCCH on the PO associated with the terminal device. Therefore, the terminal device can receive PDCCH on the PO and use P-RNTI to decode the PDCCH.

[0167] If the decoding is successful, then referring to Figure 2 , the terminal device can receive the paging message (Paging Message) at the corresponding PDSCH resource according to the paging message scheduling information (time-frequency resources, modulation and coding schemes, etc.) contained in the PDCCH.

[0168] After that, if the terminal device receives a paging message at the PDSCH resource and the paging message contains the ID of the terminal device, it means that the terminal device is paged. Correspondingly, the terminal device can initiate processes such as RRC connection establishment or RRC connection recovery to the network device, so as to respond to the paging message and receive downlink services.

[0169] However, if the terminal device does not detect the PDCCH scrambled with P-RNTI on the PO, or the paging message received at the PDSCH resource does not contain the ID of the terminal device, the terminal device considers that it is not paged and then continues to return to the sleep state.

[0170] In the paging method introduced currently, since each PO is shared by multiple terminals, in a PO, all associated terminals need to use P-RNTI to monitor the PDCCH. And among multiple terminal devices associated with the same PO, as long as one terminal device is paged, then all terminal devices associated with this PO need to further receive the paging message of the PDSCH. For the terminal devices that are not paged among them, this situation belongs to paging false alarm, and the power consumption of these terminal devices receiving the PDSCH also belongs to unnecessary power consumption waste.

[0171] In order to improve the traditional paging method introduced currently, the PEI-supported paging group is introduced, thereby reducing the power consumption of the non-paged terminals, that is, the second paging method to be introduced below.

[0172] Second: Paging method based on PEI

[0173] In this implementation method, on the basis of the traditional paging method introduced above, the PEI technology supporting paging groups is introduced, the terminal devices associated with a PO are grouped, and paging indications are respectively performed on the terminal devices in different groups, thereby reducing the paging false alarm probability.

[0174] Such as Figure 3As shown in the figure, the network device may send a PEI at a fixed position before the PO, where the PEI is also DCI (Downlink Control Information) sent in a PDCCH. Exemplarily, the DCI contains an 8-bit bitmap, and each bit corresponds to a paging packet, which is used to indicate whether the terminal device in the paging packet is paged.

[0175] Exemplarily, when the bit in the PEI is 1, it may indicate that the terminal device in the paging packet is paged; when the bit is 0, it may indicate that the terminal device in the paging packet is not paged. Or it may also be the opposite implementation, that is, 0 indicates paged and 1 indicates not paged. This embodiment does not limit this.

[0176] Referring to Figure 3 , the terminal device may correspondingly listen for the P-RNTI at the PO, that is, before performing PDCCH decoding, first listen for the PEI at a fixed position before the PO.

[0177] In one case, if the bit of the packet corresponding to the terminal device in the PEI indicates that the terminal device in the packet is paged, then the terminal device may listen for the PO according to the first paging method introduced above, that is, decode the PDCCH using the P-RNTI, and after successful decoding, receive the paging message at the PDSCH resource indicated by the PDCCH.

[0178] In another case, if the bit of the packet corresponding to the terminal device in the PEI indicates that the terminal identification in the packet is not paged, then the terminal device considers that it will not be paged, so it can return to the sleep state. This also avoids the additional power consumption caused by decoding the PDCCH and receiving the PDSCH.

[0179] The implementation of the PO and the paging cycle in the current method is similar to that introduced above, so it will not be elaborated here.

[0180] Next, in combination with Figure 4 the implementation method for determining the paging packet of the terminal device will be introduced. In this embodiment, the main network element participating in paging processing in the core network device is the AMF network element. Therefore, in Figure 4 the actions of the core network device are described with the AMF network element as the main body, and in Figure 4 the actions of the terminal device are described with the UE as the main body. However, it should be understood that in Figure 4 the example, the AMF network element can also be correspondingly replaced by the core network device, and the UE can be correspondingly replaced by the terminal device.

[0181] As Figure 4 shown, the method includes:

[0182] S401. The UE and the AMF network element negotiate the core network packet of the UE.

[0183] In this embodiment, there are two dimensions of packets for the paging packet of the UE. One dimension is the packet from the core network device to the UE, which is referred to as the core network packet of the UE in this embodiment. The other dimension is the packet determined by the network device based on the UE ID, which is referred to as the packet based on the UE ID in this embodiment.

[0184] Among them, the UE negotiates the core network packet of the UE with the core network device. Corresponding to the current step, the UE can, for example, negotiate the core network packet of the UE with the AMF network element. Exemplarily, there can be at most 8 groups of core network packets, which are sequentially represented as Packet 0 to Packet 7.

[0185] S402. The network device sends the PEI configuration to the UE.

[0186] Exemplarily, the network device can send the PEI configuration to the UE in a broadcast manner. By sending the PEI configuration to the UE, the network device informs the UE of the following two parameters: the number of packets of the core network packet and the number of packets based on the UE ID.

[0187] In one implementation, the PEI configuration can include, for example, the total number of packets supported by the PO and the number of packets based on the UE ID. Among them, the total number of packets minus the number of packets based on the UE ID is equal to the number of packets of the core network packet.

[0188] S403. When the AMF needs to page the UE, the AMF sends the core network packet of the UE to the network device.

[0189] S404. The UE and the network device determine the paging packet of the UE according to the core network packet of the UE and the PEI configuration.

[0190] It can be understood that after the network device receives the core network packet of the UE sent by the AMF, the network device masters the following information: the core network packet of the UE, the packet of the UE based on the UE ID, the number of packets of the core network packet, and the number of packets based on the UE ID.

[0191] After negotiation between the UE and the AMF, the UE can determine the core network packet of the UE; through the PEI configuration broadcast by the network device, the UE can determine the number of packets of the core network packet and the number of packets based on the UE ID. At the same time, the UE can calculate a unique packet based on the UE ID based on its own UE ID.

[0192] Therefore, based on the interaction process introduced above, the UE and the network device can obtain the same information. Subsequently, the UE and the network device can respectively determine the paging group of the UE through preset paging group determination rules. Since the input information is the same and the paging group determination rules are also the same, the UE and the network device will determine the same paging group.

[0193] After that, the network device generates and sends a PEI based on the paging group of the UE to indicate whether the paging group corresponding to the UE is being paged. Correspondingly, the UE can receive and parse the PEI based on the paging group of the UE to determine whether its own paging group is being paged.

[0194] Next, the possible implementation methods of the paging group determination rules will be introduced:

[0195] First, the following two parameters are described:

[0196] - subgroupsnumperpo: The total number of core network groups (if any) and UE ID-based groups (if any) supported in a PO. This parameter can be broadcast in the system information and corresponds to the total number of groups introduced above.

[0197] - subgroupsNumForUEID: The number of UE-ID-based groups in a PO. This parameter is also broadcast in the system information and corresponds to the number of UE ID-based groups introduced above.

[0198] Based on this, the paging group determination rule can be:

[0199] Case 1: If subgroupsNumForUEID is not present in the subgroupConfig, and the core network group of the UE is available to the UE, then the core network group of the UE in the cell is used as the paging group.

[0200] Case 2: If both subgroupsNumPerPO and subgroupsNumForUEID are configured in the subgroupConfig, and the value of subgroupsNumForUEID is the same as the value of subgroupsNumPerPO, then the UE ID-based group of the UE in the cell is used as the paging group.

[0201] Case 3: If both subgroupsNumPerPO and subgroupsNumForUEID are configured in the subgroupConfig, and subgroupsNumForUEID < subgroupsNumPerPO, then it is further divided into the following cases:

[0202] - If the core network packet of the UE is available to the UE, the core network packet of the UE is used as the paging packet in the cell.

[0203] - If the core network packet of the UE is not available to the UE, the UE ID-based packet of the UE is used as the paging packet in the cell.

[0204] Case 4: If the UE does not have a core network packet or does not support a core network packet, and subgroupsNumForUEID is not configured, the UE directly monitors the PO.

[0205] The above introduced the related implementation of the paging method based on PEI. Next, the last paging method will be introduced.

[0206] The third, paging method based on WUS

[0207] In this implementation method, the introduction of a low-power wake-up signal (Wake Up Signal, WUS) / wake-up receiver (Wake Up Receiver, WUR) is further considered. That is, WUS / WUR is introduced before the PO. For terminal devices that are not paged, the more simply detected WUS is used to replace the traditional paging reception operation of performing PDCCH detection at the PO, thereby saving the power consumption of receiving paging.

[0208] For the first traditional paging method introduced above, since the terminal needs to monitor the P-RNTI at the PO, that is, perform PDCCH decoding, the main receiver needs to be woken up before the PO. Then, in order to reduce the power consumption of the terminal device, a lower-power receiver, that is, an LR (Low power Receiver) or a WUR, is considered. This receiver can receive a simpler WUS (possibly only sequence-related, without performing PDCCH decoding), so the power consumption is lower.

[0209] Specifically, the main radio frequency interface corresponding to the main transceiver is mainly used to interact with the network device, obtain the downlink data sent by the core network device through the network device, and receive complex messages sent by other network devices, etc., and send data and various other messages to the network device. And it is only used to receive some relatively simple signals, such as WUS, etc. Therefore, the power consumption of the WUR is lower than that of the MR.

[0210] It can be understood with reference to Figure 5 When the terminal device monitors paging, it only needs to start the LR (or WUR) before the PO to detect the WUS. If the WUS is not detected, the terminal device can continue to sleep. If the WUS is detected, the terminal device further wakes up the MR to monitor the paging message.

[0211] In the paging method introduced currently, for example, WUS can be combined with the PEI introduced above. Referring to Figure 5 , after detecting WUS, the terminal device can wake up the MR. Then, based on the MR, the PEI is received first before the PO. When the PEI indicates that the paging packet of the terminal device is paged, the terminal device then decodes the PDCCH using the P-RNTI and receives the paging message at the PDSCH resource indicated by the PDCCH.

[0212] Alternatively, the WUS mechanism can also be used alone without combining with the PEI mechanism. For example, referring to Figure 5 , after detecting WUS, the terminal device can also wake up the MR. Then, directly based on the MR, the PDCCH is decoded using the P-RNTI, and after successful decoding, the paging message is received at the PDSCH resource indicated by the PDCCH.

[0213] This embodiment does not limit the specific relationship between these two mechanisms. However, generally speaking, based on both the PEI mechanism and the WUR mechanism, the power consumption of the terminal device for periodic paging monitoring can be effectively reduced.

[0214] The above introduces multiple possible paging methods. On the premise that there are multiple possible paging methods, since the idle-state and inactive-state terminal devices are invisible to the network device in the cell, if the network device uses one paging method to send paging messages while the terminal device uses another paging method to receive paging messages, paging anomalies may occur.

[0215] Moreover, different paging methods used by the terminal device and the network device may cause the paging method set for power saving purposes to fail to achieve the effect of power saving. For example, assume that the network device uses a paging method based on WUS to send paging messages to the terminal device. However, on the premise that the terminal device supports the paging method based on WUS, if the terminal device still uses the traditional paging method to receive paging messages, then the paging method based on WUS does not play the role of power saving, resulting in a relatively high power consumption for the terminal device to monitor paging messages.

[0216] Therefore, a reasonable paging process should be designed so that both the terminal device and the network device can know which paging technology should be used for the current terminal device. At present, there is no clear solution and idea for this.

[0217] Therefore, the present application proposes the following technical concept: The paging configurations of both parties can be aligned between the terminal device and the network device through signaling interaction. Then, based on a preset rule, the terminal device and the network device respectively determine the same paging method according to the aligned paging configurations of both parties, so that for terminal devices in the idle state and the inactive state, the terminal device and the network device can use the same paging method to perform the paging process, thereby avoiding the paging anomalies or high power consumption problems introduced above.

[0218] First, in combination with Figure 6 the paging method determination method provided by the present application will be introduced. Figure 6 is the signaling interaction of the paging method determination method provided by the embodiments of the present application Figure 1 .

[0219] As Figure 6 shown, the method includes:

[0220] S601. The network device sends first indication information to the terminal device, where the first indication information is used to indicate the first paging method supported by the network device.

[0221] Among them, the network device can send the first indication information to the terminal device to inform the terminal device of the paging methods supported by the current network device. In this embodiment, the paging methods supported by the network device are referred to as the first paging method. Among them, the first paging method supported by the network device may include one or more paging methods.

[0222] In addition, the "network device support" in this embodiment can be understood from the following two aspects: On the one hand, from the perspective of the capabilities of the network device, the paging methods that the network device itself can support in terms of capabilities are referred to as the first paging method. On the other hand, from the perspective of the inclination of the network device, on the premise that the capabilities of the network device permit, the paging methods that the network device wants to support (or wants to adopt) according to the current actual situation can be referred to as the first paging method. In the actual implementation process, how to specifically understand "support" can be determined according to actual needs.

[0223] Exemplarily, the first paging method may include at least one of the following: the paging method of parsing the PDCCH in the PO, the paging method based on the PEI, and the paging method based on the WUS. These three paging methods have been introduced in detail in the above embodiments and will not be elaborated here.

[0224] In one implementation manner, the network device can send the first indication information to the terminal device in a broadcast manner. Exemplarily, it can be sent through a system broadcast.

[0225] Alternatively, when the terminal device accesses the network device, the network device may also send the first indication information to the terminal device in a unicast manner. This embodiment does not limit the sending manner of the first indication information.

[0226] In addition, for example, after the paging manner configuration is completed, the network device may send the first indication information to the terminal device only once and then will not send it repeatedly. This implementation manner can effectively save signaling overhead.

[0227] Alternatively, the network device may also periodically send the first indication information to the terminal device at a preset time interval. Alternatively, the network device may also send the first indication information to the terminal device each time the terminal device accesses. For the two sending timings of the first indication information introduced above, it can be ensured that the terminal device can learn the first paging manner of the network device.

[0228] In addition, when the first paging manner of the network device is updated, the network device may also send the first indication information to the terminal device to inform the terminal device of the updated first paging manner of the network device.

[0229] In the actual implementation process, the sending moment, or rather the sending timing, of the network device sending the first indication information to the terminal device can be selected and set according to actual requirements. This embodiment does not limit this.

[0230] S602. The core network device determines the second paging manner corresponding to the terminal device.

[0231] In this embodiment, in order to enable the terminal device and the network device to use the same paging manner to transmit paging messages, it is necessary to ensure that the terminal device and the network device can learn each other's paging manners.

[0232] Among them, the terminal device can inform the network device of the paging manner supported by the terminal device through signaling interaction. However, after the RRC connection between the terminal device and the network device is released, the network device usually will no longer save the paging manner informed by the terminal device. Therefore, simply informing the network device of the paging manner by the terminal device is unstable.

[0233] Therefore, in this embodiment, the core network device will determine the second paging manner corresponding to the terminal device, and the second paging manner corresponding to the terminal device can be stably saved in the core network device. When the core network device needs to page the terminal device later, the core network device can inform the network device of the second paging manner corresponding to the terminal device, so that the purpose of the network device learning the second paging manner of the terminal device can be achieved.

[0234] In one implementation, the second paging method in this embodiment may be the paging method reported by the terminal device and supported by the terminal device. Alternatively, the second paging method in this embodiment may also be the paging method negotiated between the terminal device and the core network device and adopted by the terminal device.

[0235] Similarly, the second paging method corresponding to the terminal device may also include one or more paging methods. Exemplarily, the first paging method may include at least one of the following: the paging method of parsing the PDCCH in the PO, the paging method based on the PEI, and the paging method based on the WUS. These three paging methods have been introduced in detail in the above embodiments and will not be elaborated here.

[0236] It should be noted that this embodiment does not limit the execution order of S601 and S602. For example, S601 may be executed first, and then S602; or S602 may be executed first, and then S601; or S601 and S602 may be executed in parallel. The specific execution order can be selected according to actual requirements.

[0237] S603. The core network device sends a paging message to the network device, and the paging message includes the second paging method corresponding to the terminal device.

[0238] Furthermore, when the core network device needs to page the terminal device, the core network device may send a paging message to the network device, where the paging message is used to page the terminal device. In this embodiment, the paging message may also include the second paging method corresponding to the terminal device to inform the network device of the second paging method corresponding to the terminal device.

[0239] The method of carrying the second paging method corresponding to the terminal device in the paging message introduced here is one implementation. In another implementation, when the core network device needs to page the terminal device, the core network device may send a paging message to the network device. In addition, the core network device may also send additional notification information to the network device, where the notification information is used to indicate the second paging method corresponding to the terminal device. In this implementation, the notification information and the paging message may be two independent messages.

[0240] S604. The terminal device and the network device respectively determine the target paging method according to the first paging method and the second paging method.

[0241] For a terminal device, the terminal device learns about the first paging mode supported by the network device through the first indication information sent by the network device. And the terminal device can determine the second paging mode corresponding to the terminal device. Specifically, whether the terminal device reports the paging mode it supports or the terminal device and the core network device negotiate the paging mode to be used, in short, the terminal device can determine its corresponding second paging mode.

[0242] At the same time, for the network device, the network device can learn about the second paging mode corresponding to the terminal device through the paging message sent by the core network device. And the network device can determine the first paging mode it supports.

[0243] Therefore, in this embodiment, the terminal device and the network device can align the first paging mode and the second paging mode with each other. After that, the terminal device and the network device can respectively determine the target paging mode according to the first paging mode and the second paging mode.

[0244] Exemplarily, the terminal device can determine the target paging mode from the first paging mode and the second paging mode according to a preset rule, and then receive the paging message sent by the network device according to the target paging mode.

[0245] And, the network device can determine the target paging mode from the first paging mode and the second paging mode according to the same preset rule, and then send the paging message to the terminal device according to the target paging mode.

[0246] Because the terminal device and the network device align the first paging mode and the second paging mode with each other, and at the same time will determine the target paging mode based on the same preset rule, it can be ensured that the target paging mode determined by both parties is the same. After that, the network device and the terminal device will implement the transmission of the paging message based on the same target paging mode, so as to ensure that the terminal device can correctly receive the paging, and when the target paging mode has the effect of power saving, it can also ensure that the power saving effect can be normally exerted.

[0247] Based on the introduction of the above embodiments, it can be determined that there are two different implementations for the core network device to determine the second paging mode corresponding to the terminal device. The following will further introduce the specific steps of these two implementations respectively.

[0248] One implementation is that the terminal device can directly report the paging mode it supports, and the corresponding second paging mode is the paging mode supported by the terminal device.

[0249] The following will describe this situation in conjunction with Figure 7 to illustrate this case. Figure 7 is the signaling interaction of the paging mode determination method provided by the embodiment of the present applicationFigure 2 。

[0250] As Figure 7 shown, the method includes:

[0251] S701. The network device sends first indication information to the terminal device, where the first indication information is used to indicate the first paging mode supported by the network device.

[0252] Among them, the implementation manner of S701 is the same as that of S601 introduced above, and will not be elaborated here.

[0253] S702. The terminal device sends second indication information to the network device, where the second indication information is used to indicate the second paging mode supported by the terminal device.

[0254] Furthermore, "the core network device determines the second paging mode corresponding to the terminal device" introduced in the above embodiments can be implemented through the steps of S702 and S703 in the current embodiment.

[0255] In this embodiment, the terminal device can send second indication information to the network device. The purpose of the second indication information is to inform the device that receives the second indication information of the second paging mode supported by the terminal device. That is to say, the terminal device will report the second paging mode it supports through the second indication information.

[0256] In addition, the "supported by the terminal device" in this embodiment can also be understood from the following two aspects: On the one hand, from the perspective of the capabilities of the terminal device, the paging mode that the terminal device itself can support in terms of capabilities is called the second paging mode. On the other hand, from the perspective of the preferences of the terminal device, on the premise that the capabilities of the terminal device permit, the paging mode that the terminal device wants to support (or wants to adopt) according to the current actual situation can be called the second paging mode. In the actual implementation process, how to specifically understand "supported" can be determined according to actual needs.

[0257] It can be understood that the terminal device can only report relevant uplink data to the network device when it establishes an RRC connection with the network device. Therefore, the terminal device can send the second indication information to the network device when it is in the RRC connected state.

[0258] In one implementation manner, for example, the terminal device can send the second indication information to the network device when it first establishes an RRC connection with the network device, and then does not send it repeatedly. Until the second paging mode supported by the terminal device is updated, the terminal device sends the second indication information to the network device again when it is in the RRC connected state. This implementation manner can save signaling overhead.

[0259] Alternatively, the terminal device may also send second indication information to the network device each time it establishes an RRC connection with the network device. This implementation can ensure that the second paging method of the terminal device can be effectively reported to the network device.

[0260] Alternatively, the terminal device may also send second indication information to the network device in response to a request from the network device. This embodiment does not particularly limit the triggering timing for the terminal device to send the second indication information.

[0261] S703. The network device sends second indication information to the core network device. The second indication information is used to indicate the second paging method supported by the terminal device.

[0262] After receiving the second indication information, the network device may send the second indication information to the core network device again. Similarly, the second indication information is used for the second paging method supported by the terminal device, so as to inform the core network device of the second paging method supported by the terminal device.

[0263] Among them, after receiving the second indication information sent by the terminal device, the network device may perform relevant processing that the network device should perform on the second indication information. Then, the processed second indication information is sent to the core network device. In such an implementation, it is the terminal device and the network device that interact, and then the network device and the core network device interact. Correspondingly, the signaling used for the second indication information sent by the terminal device is the AS signaling.

[0264] Alternatively, the network device may not perform any processing on the second indication information after receiving the second indication information sent by the terminal device. The network device is only responsible for forwarding the second indication information to the core network device. In such an implementation, it can be understood that the terminal device directly interacts with the core network device to inform the core network device of the second paging method supported by the terminal device. Correspondingly, the signaling used for the terminal device to send the second indication information is the NAS signaling.

[0265] This embodiment does not limit the specific interaction method of the terminal device. In short, it can be achieved to inform the core network device of the second paging method supported by the terminal device.

[0266] S704. The core network device sends a paging message to the network device. The paging message includes the second paging method corresponding to the terminal device.

[0267] S705. The terminal device and the network device respectively determine the target paging method according to the first paging method and the second paging method.

[0268] Among them, the implementation manners of S704 and S705 are the same as those of S603 and S604 introduced above, and will not be elaborated here.

[0269] In this embodiment, the terminal device sends second indication information to the network device, and then the network device sends the second indication information to the core network device, so that the second paging method supported by the terminal device can be effectively informed to the core network device through the second indication information.

[0270] Another implementation is that the terminal device informs the core network device of the paging method it supports, and then the core network device and the terminal device negotiate the paging method adopted by the terminal device based on the paging method supported by the terminal device. In this embodiment, the paging method supported by the terminal device is called the third paging method, and the paging method negotiated by the terminal device and the core network device is called the second paging method.

[0271] Next, combined with Figure 8 this situation will be described. Figure 8 is the signaling interaction of the paging method determination method provided in the embodiment of the present application Figure 3 .

[0272] As Figure 8 shown, the method includes:

[0273] S801. The network device sends first indication information to the terminal device, where the first indication information is used to indicate the first paging method supported by the network device.

[0274] Among them, the implementation manner of S801 is the same as the implementation manner of S801 introduced above, and will not be elaborated here.

[0275] S802. The terminal device sends third indication information to the core network device, and the third indication information is used to indicate the third paging method supported by the terminal device.

[0276] Furthermore, the "core network device determines the second paging method corresponding to the terminal device" introduced in the above embodiment can be implemented through the steps of S802 and S803 in the current embodiment.

[0277] In this embodiment, the terminal device can send third indication information to the core network device, and the purpose of the third indication information is to inform the core network device of the third paging method supported. The third indication information here is similar to the second indication information introduced in the above embodiment, so the third indication information will not be elaborated in this embodiment.

[0278] However, it should be noted that in this embodiment, the terminal device sends the third indication information directly to interact with the core network device to inform the core network device of the third paging method supported by the terminal device. Therefore, the signaling used by the terminal device to send the third indication information is NAS signaling.

[0279] Further, in addition to indicating the third paging mode, the third indication information may also indicate, for example, the preference of the terminal device. For example, if the terminal device supports multiple third paging modes, and the terminal device prefers to use one or more of these multiple paging modes to receive paging messages, the preference of the terminal device can be indicated by the third indication information.

[0280] S803. The core network device sends first configuration information to the terminal device, and the first configuration information is used to indicate the second paging mode corresponding to the terminal device.

[0281] After receiving the third indication information sent by the terminal device, the core network device can determine the third paging mode supported and indicated by the terminal device. Further, when the third indication information indicates the preference of the terminal device, the core network device can also determine, for example, the paging mode that the terminal device prefers in the third paging mode.

[0282] After that, the core network device can determine, for example, the second paging mode that is allowed for the terminal device to use or specified for the terminal device to use among the third paging modes supported by the terminal device, which is correspondingly the second paging mode corresponding to the terminal device in this embodiment.

[0283] In one implementation manner, after the core network device learns about the third paging modes supported by the terminal device, if it is determined that all these third paging modes are allowed for the terminal device to use, the core network device can send first configuration information to the terminal device. The first configuration information may be, for example, a confirmation message, and the confirmation message is used to indicate the confirmation of the third paging modes. That is to say, the core network device can directly determine the third paging modes supported by the terminal device as the second paging mode, and through the first configuration information (such as a confirmation message), inform the terminal device that the third paging modes it supports are all used as the second paging mode after negotiation.

[0284] In another implementation manner, in addition to learning about the third paging modes supported by the terminal device, the core network device can also learn about the preference of the terminal device. If the core network device determines that at least one paging mode preferred by the terminal device is allowed for the terminal device to use, the core network device can send first configuration information to the terminal device. The first configuration information may be, for example, a confirmation message, and the confirmation message is used to indicate the confirmation of at least one paging mode preferred by the terminal device. That is to say, the core network device determines at least one paging mode preferred by the terminal device as the second paging mode, and through the first configuration information (such as a confirmation message), inform the terminal device that at least one paging mode it prefers is used as the second paging mode after negotiation.

[0285] In another implementation, when the core network device learns about the third paging method supported by the terminal device and can also learn about the preference selection of the terminal device, the core network device can refer to this data and select at least one paging method that allows (or indicates) the terminal device to use from the third paging methods supported by the terminal device. Then, the at least one paging method selected from the third paging methods is used as the negotiated second paging method. And the core network device can indicate the second paging method through the first configuration information to implement the negotiation of the second paging method between the core network and the terminal device.

[0286] S804. The core network device sends a paging message to the network device, and the paging message includes the second paging method corresponding to the terminal device.

[0287] S805. The terminal device and the network device respectively determine the target paging method according to the first paging method and the second paging method.

[0288] Among them, the implementation manners of S804 and S805 are the same as those of S603 and S604 introduced above, and will not be elaborated here.

[0289] In this embodiment, the terminal device sends the third indication information to the core network device. Then, the core network device selects at least one paging method from the third paging methods supported by the terminal device according to the third indication information reported by the terminal device, and uses the selected paging method as the second paging method negotiated between the terminal device and the core network. Then, it notifies the terminal device through the first configuration information, so that the negotiation of the second paging method between the terminal device and the core network device can be realized.

[0290] And in the current embodiment, since the paging packet of the above-introduced PEI is determined by the core network device, the terminal device and the core network device directly interact, so that the core network device determines the second paging information corresponding to the terminal device. This is beneficial for the collaborative use of WUS and PEI. For example, it can reduce the signaling overhead and / or reduce the implementation difficulty, etc.

[0291] Based on the various situations introduced in the above embodiments, the first indication information sent by the network device will be further described below.

[0292] Among them, the first indication information is used to indicate the first paging method supported by the network device. The indication of the first paging method by the first indication information may have the following two implementation manners:

[0293] 1. The first indication information includes the first paging method

[0294] In this implementation manner, that is, the first indication information directly indicates the first paging manner. Exemplarily, for example, the identity information of the first paging manner may be included in the first indication information, so as to realize the direct indication of the first paging manner.

[0295] The identity information of each paging manner may be, for example, pre-negotiated or may also be dynamically configured. This embodiment does not limit this.

[0296] 2. The first indication information is paging configuration information

[0297] Among them, in order to realize the smooth transmission of paging messages, the network device usually also needs to send paging configuration information to the terminal device. The paging configuration information is used to indicate the time-frequency resources, scrambling methods, etc. of the downlink messages related to paging (such as PEI, WUS, etc.), so that the terminal device can determine the configuration of the downlink messages related to paging, and then can smoothly receive paging messages. The specific configuration included in the paging configuration message can be selected according to actual needs. This embodiment does not limit this.

[0298] On this basis, because the paging configuration message is used to indicate the configuration of the downlink messages related to paging, when the network device sends the paging configuration message of some downlink messages to the terminal device, it can implicitly indicate that the network device supports the paging manner corresponding to these downlink messages. Therefore, in the current implementation manner, the paging configuration information can be used as the first indication information.

[0299] Among them, when the network device supports multiple paging manners, the network device can send multiple paging configuration messages to the terminal device. Therefore, the first indication information may include at least one paging configuration information.

[0300] If the paging configuration information of WUS is included in the first indication information, that is, the network device sends the paging configuration information of WUR to the terminal device, it correspondingly implicitly indicates that the network device supports the paging manner based on WUS. Therefore, it can be determined that the first paging manner includes the paging manner based on WUS.

[0301] And, if the paging configuration information of PEI is included in the first indication information, that is, the network device sends the paging configuration information of PEI to the terminal device, it correspondingly implicitly indicates that the network device supports the paging manner based on PEI. Therefore, it can be determined that the first paging manner includes the paging manner based on PEI.

[0302] Among them, the first indication information may include both the paging configuration information of WUS and the paging configuration information of PEI. Therefore, the first paging manner may, for example, include both the paging manner based on WUS and the paging manner based on PEI at the same time.

[0303] For the implementation of indirectly indicating the first paging method through paging configuration information, whether the first paging method includes the paging method of "decoding PDCCH in the PO periodically" can be implemented in the following ways.

[0304] In one implementation, it can be pre-configured that the default network device supports the paging method of decoding PDCCH in the PO periodically. That is to say, the first paging method fixedly includes the paging method of decoding PDCCH in the PO periodically.

[0305] In another implementation, if the terminal device has neither received the paging configuration information of PEI sent by the network device nor received the paging configuration information of WUS sent by the network device, then the terminal device can confirm that the network device supports the paging method of decoding PDCCH in the PO periodically. That is to say, in this case, the first paging method includes the paging method of decoding PDCCH in the PO periodically.

[0306] Or, a specific downlink information can also be determined for the paging method of "decoding PDCCH in the PO periodically". When the paging configuration information of this specific downlink information is included in the first indication information, that is, when the network device sends the paging configuration message of this specific downlink information to the terminal device, it correspondingly implicitly indicates that the network device supports the paging method of decoding PDCCH in the PO periodically.

[0307] In this embodiment, the first indication information can be used to quickly and accurately indicate the first paging method in a direct indication manner. Or, the paging configuration information can be determined as the first indication information, so as to indirectly indicate the first paging method. At the same time, this implementation method can reuse the paging configuration information sent by the network device to indicate the first paging method, so that the signaling overhead can be effectively saved.

[0308] The above embodiments introduce the implementation methods of the first indication information indicating the first paging method. Next, the implementation methods of the second indication information in this application will be briefly introduced.

[0309] Among them, the second indication information is used to indicate the second paging method supported by the terminal device. There are, for example, the following two implementation methods for the second indication information to indicate the second paging method:

[0310] 1. The second indication information includes the second paging method

[0311] In this implementation manner, that is, the second indication information directly indicates the second paging manner. Exemplarily, for example, the identity information of the second paging manner may be included in the second indication information, so as to directly indicate the second paging manner.

[0312] The identity information of each paging manner may be, for example, pre-negotiated or may also be dynamically configured. This embodiment does not limit this.

[0313] 2. The receiver type is included in the second indication information

[0314] Regarding the several paging manners introduced above, it can be understood that there are certain differences in the receivers used for different paging manners. Therefore, the corresponding relationship between the receiver and the paging manner can be determined. Then, by including the receiver type in the second indication information, the indication of the second paging manner can be realized. The receiver type in this embodiment may include at least one of the following: low-power receiver (LR) and main receiver (MR).

[0315] In one implementation manner, if the receiver type in the second indication information only includes a low-power receiver, since a low-power receiver is required to receive WUS, it can be confirmed that the second paging manner includes: a paging manner based on WUS.

[0316] Or, if the second indication information only includes the main receiver, since the main receiver is required to receive PEI and to receive PDCCH within the PO period, it can be confirmed that the second paging manner includes: a paging manner based on PEI and a paging manner of decoding PDCCH in the PO periodically.

[0317] Or, if the receiver type in the second indication information includes both a low-power receiver and a main receiver, then combining the above two cases, it can be confirmed that the second paging manner includes: a paging manner based on WUS, a paging manner based on PEI, and a paging manner of decoding PDCCH in the PO periodically.

[0318] 3. Parameters associated with the paging manner are included in the second indication information

[0319] Similar to the above embodiment, in order to realize the smooth transmission of paging messages, the terminal device usually needs to report paging-related parameters to the network device. On this basis, some of the parameters that the terminal device needs to report are associated with specific paging manners. Then, when the terminal device sends certain parameters to the network device, the paging manners corresponding to these parameters supported by the terminal device can be implicitly indicated. Therefore, in the current implementation manner, the parameters associated with the paging manner can be used as the first indication information.

[0320] In this embodiment, the parameters associated with the paging mode can be collectively referred to as the first parameters. When the terminal device supports multiple paging modes, the terminal device can send multiple first parameters to the network device. Therefore, the second indication information may include at least one first parameter.

[0321] Exemplarily, the first parameter of the MR wake-up time is associated with the paging mode based on WUS. Among them, the MR wake-up time represents the minimum time required for the terminal to wake up the MR to monitor the PDCCH related to paging from the start of receiving or receiving the wake-up signal of the LR. Then when the second indication information includes the MR wake-up time, that is, when the terminal device sends the MR wake-up time to the network device, it correspondingly implicitly indicates that the terminal device supports the paging mode based on WUS. Therefore, it can be determined that the second paging mode includes the paging mode based on WUS.

[0322] In this embodiment, the second indication information can quickly and accurately indicate the second paging mode by means of direct indication. Or, the receiver type may also be included in the second indication information, so as to indirectly indicate at least the second paging mode. Or, the first parameter sent by the terminal device may be determined as the second indication information, so as to indirectly indicate the second paging mode. At the same time, this implementation method can reuse the first parameter sent by the terminal device to indicate the second paging mode, so as to effectively save signaling overhead.

[0323] Further, when sending the second indication information, the terminal device may, for example, send it through UE capability information. Or any other possible signaling may also be used to send the second indication information, and this embodiment does not make special limitations thereon.

[0324] Based on the above embodiment, an additional explanation is required for the paging mode of "decoding the PDCCH in the PO periodically".

[0325] Since the paging mode of "decoding the PDCCH in the PO periodically" is a relatively traditional paging mode, for example, it can be set that the network device (or the terminal device) defaults to support this paging mode. Then, this paging mode does not need to be additionally indicated in the first indication information (or the second indication information). The network device can also determine that the terminal device supports this paging mode. Correspondingly, the terminal device can also determine that the network device supports this paging mode. Based on this implementation method, signaling overhead can be effectively saved.

[0326] Alternatively, the above-introduced default configuration may not be set, and then it is possible to indicate in the first indication information (or the second indication information) whether the network device (or the terminal device) can adopt this paging method. Based on this implementation method, flexible configuration of whether the network device (or the terminal device) supports the traditional paging method can be achieved.

[0327] This embodiment does not particularly limit the indication method of the traditional paging method, and it can be selected according to actual needs.

[0328] The above introduced the related implementation of the second indication information indicating the second paging method. Actually, for the implementation of the third indication information indicating the third paging method and the first configuration information indicating the second paging method when the core network designates the terminal device to adopt certain paging methods, it is similar to the implementation of the second indication information. Therefore, the implementation of the third indication information and the first configuration information will not be elaborated in this application, and it can refer to the content introduced in the above embodiments.

[0329] Based on the above-introduced content, the implementation methods for the terminal device and the network device to determine the target paging method will be introduced below. Among them, the terminal device will determine the target paging method based on a preset rule according to the first paging method and the second paging method. And the network device will determine the target paging method based on the same preset rule according to the first paging method and the second paging method.

[0330] Then it can be understood that the terminal device and the network device will perform similar processing respectively to determine the same target paging method. Therefore, the following content will not distinguish between the terminal device and the network device, and the implementation of determining the target paging method will be described. It can be understood that both the terminal device and the network device will execute the following content.

[0331] Among them, there are generally the following two implementation methods for determining the target paging method:

[0332] Implementation method 1: Determine the target paging method according to the priority of the paging method.

[0333] Specifically, the paging method with the highest priority among at least one paging method that exists in both the first paging method and the second paging method can be determined as the target paging method.

[0334] Because the priority of the paging method is usually set for some consideration, based on this rule, the optimal paging method for some consideration can be determined as the target paging method on the premise that both parties support it, so as to improve the paging effect to a certain extent.

[0335] In one implementation method, it is possible to refer to Figure 9 understand the priority of multiple paging methods, Figure 9Schematic diagram for implementing the determination of the target paging method provided by the embodiments of this application.

[0336] As Figure 9 shown, the priorities of multiple paging methods can be: the priority of the paging method based on WUS > the priority of the paging method based on PEI > the priority of the paging method of decoding PDCCH in PO periodically.

[0337] And with reference to Figure 9 , it is assumed that the first paging method includes the paging method based on WUS and the paging method of decoding PDCCH in PO periodically, that is, the network device supports these two paging methods.

[0338] And it is assumed that the second paging method includes: the paging method based on WUS, the paging method based on PEI, and the paging method of decoding PDCCH in PO periodically, that is, the terminal device can adopt these three paging methods.

[0339] Then in the Figure 9 schematic, it can be determined that the "paging method based on WUS" and the "paging method of decoding PDCCH in PO periodically" are the paging methods that exist in both the first paging method and the second paging method, and the paging method with the highest priority among these two paging methods is the "paging method based on WUS", so it can be confirmed that the target paging method is the "paging method based on WUS".

[0340] The above Figure 9 priority of the example paging method is only one possible implementation. In the actual implementation process, the priority of the paging method can be selected and set according to actual needs, and this embodiment does not limit this. For example, the priority of multiple paging methods can also be any one of the following:

[0341] The priority of the paging method based on WUS > the priority of the paging method of decoding PDCCH in PO periodically > the priority of the paging method based on PEI;

[0342] The priority of the paging method of decoding PDCCH in PO periodically > the priority of the paging method based on WUS > the priority of the paging method based on PEI;

[0343] The priority of the paging method based on PEI > the priority of the paging method based on WUS > the priority of the paging method of decoding PDCCH in PO periodically;

[0344] The priority of the paging method based on PEI > the priority of the paging method of decoding PDCCH in PO periodically > the priority of the paging method based on WUS;

[0345] The priority of the paging method for decoding PDCCH in the PO by cycle > the priority of the paging method based on PEI > the priority of the paging method based on WUS.

[0346] Here, a brief introduction to the configuration method of the priority is given again.

[0347] In one implementation, the priority of the paging method can be, for example, pre-set. In this implementation, both the terminal device and the network device will synchronize the pre-set priority of the paging method to ensure that the priorities of both sides are aligned.

[0348] Alternatively, the priority of the paging method can also be, for example, dynamically configured to the terminal device after being determined by the network device. For example, the network device can send second configuration information to the terminal device, where the second configuration information is used to indicate the priority of each paging method.

[0349] Implementation method 2: Determine the target paging method according to a pre-defined table.

[0350] In this implementation, a first table can be pre-defined, and at least one paging combination and its corresponding paging method can be stored in the first table, where the paging combination is exactly composed of the paging method corresponding to the terminal device (i.e., the second paging method) and the paging method corresponding to the network device (i.e., the first paging method). Then, by referring to the first table, the paging method corresponding to the first paging combination formed by the first paging method and the second paging method in the first table can be determined as the target paging method.

[0351] For example, it can be understood by referring to Figure 10 as follows. Figure 10 This is a schematic diagram of the implementation of the first table provided by the embodiments of the present application.

[0352] In Figure 10 the example, the row direction of the table is the paging method corresponding to the network device (i.e., the first paging method), and the column direction of the table is the paging method corresponding to the terminal device (i.e., the second paging method).

[0353] Referring to Figure 10 it can be understood that in the first table, the paging methods corresponding to various combinations formed by the first paging method and the second paging method are directly listed.

[0354] In Figure 10 the example, assume that the paging method of "decoding PDCCH in the PO by cycle" (that is, Figure 10If the "traditional" (in []) is supported by default for both the terminal device and the network device, then the first paging method indicated by the first indication information may include a paging method based on WUS and / or a paging method based on PEI, and similarly, the second paging method indicated by the second indication information may also include a paging method based on WUS and / or a paging method based on PEI.

[0355] Exemplarily, if the first paging method includes a paging method based on WUS and a paging method based on PEI, and the second paging method also includes a paging method based on WUS and a paging method based on PEI, then by referring to Figure 10 the table, it can be determined that the paging method corresponding to the first paging combination formed by the current example is: the paging method based on WUS. Therefore, the paging method based on WUS can be determined as the target paging method.

[0356] Also, if the first paging method is empty, or the second paging method is empty, since the default terminal device and network device both support the traditional paging method (i.e., the paging method of decoding PDCCH in the PO periodically), therefore, by referring to the first table, the traditional paging method can be determined as the target paging method.

[0357] No further elaboration will be made here on Figure 10 the remaining combination cases in [].

[0358] In the actual implementation process, the specific implementation of the first table can be set according to actual needs, and this embodiment does not make special restrictions on this.

[0359] Referring to Figure 10 the schematic first table, it can be understood that actually Figure 10 when determining the target paging method for the combination of multiple paging methods in [], it is still determined according to a certain priority, thus forming the first table. The reason for converting the priority into the rise and fall of the first table is that the first table is pre-constructed and stored in both the terminal device and the network device. In this way, when determining the target paging method, the result can be directly obtained by querying the first table, thereby omitting the device judgment process and improving the speed of determining the target paging method to a certain extent.
