Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a paging monitoring method, a terminal, and a network-side device. Background Art

[0002] In the prior art, for a non-connected terminal, the time-domain positions for monitoring paging messages and short messages are the same, and the monitoring periods are both the minimum value min{the terminal-specific monitoring period, the cell-common monitoring period}. Among them, the cell-common monitoring period is the discontinuous reception (DRX) period broadcast by the current cell, which is generally determined according to the frequency of short messages that the terminal needs to monitor in the current cell. The short messages are used to notify the earthquake and tsunami warning system (ETWS) / commercial mobile alert system (CMAS) and system message changes. The terminal-specific monitoring period is configured by the network using dedicated signaling, and is often configured by the network according to the paging message monitoring period or DRX period recommended by the terminal.

[0003] When the cell-common monitoring period is less than the terminal-specific monitoring period, the power consumption of the terminal increases without obvious benefits. This is because the terminal only needs to monitor the physical downlink control channel (PDCCH) at the paging occasion (PO) when monitoring short messages, while receiving paging messages requires monitoring the PDCCH and receiving the corresponding physical downlink shared channel (PDSCH) at the PO. The measurements required for the terminal to receive the PDCCH and receive the PDSCH are different. In the case of poor channel conditions, the terminal may need to measure 1 synchronization signal block (SSB) before the PO for receiving the PDCCH, while it may need to measure 3 SSBs before receiving the PDSCH. That is, when the cell-common monitoring period is less than the terminal-specific monitoring period, more intensive monitoring of paging messages brings more power consumption for terminal measurements, but the gain in paging delay reduction brought by it may not have obvious benefits for the terminal because the terminal-specific monitoring period itself is closer to the actual service delay requirement of the terminal.

[0038] To facilitate a clearer understanding of the technical solutions of the embodiments of this application, some technical content related to the embodiments of this application will be introduced first.

[0039] 1. Paging:

[0040] Paging includes two functions:

[0041] (1) When downlink services arrive, the network sends a paging message to Radio Resource Control (RRC) IDLE / INACTIVE state terminals.

[0042] (2) Send system message change notifications, Earthquake and Tsunami Warning System (TWS) / Commercial Mobile Alert Service (CMAS) notifications to RRC IDLE / INACTIVE / CONNECTED terminals via short messages.

[0043] Among them, the ETWS notification and the CMAS notification are collectively referred to as the Public Warning System (PWS) notification.

[0044] For an RRC IDLE / INACTIVE UE, the terminal calculates its own paging occasion PO (the paging monitoring occasion jointly determined by the terminal based on its own UE ID and the paging parameters broadcast by the cell), and periodically monitors the PDCCH at this PO using the Paging Radio Network Temporary Identifier (P-RNTI) to receive paging messages and short messages. Among them, the short message is directly carried by the PDCCH, while the paging message is carried by the PDSCH, that is, the terminal first monitors the paging on the PDCCH and then receives the paging message on the PDSCH.

[0045] For a connected terminal, the terminal listens for at least one short message at any paging position within each DRX cycle according to the cell-common monitoring period.

[0046] 2. Paging DRX cycle: Downlink services may arrive, system messages may change, and ETWS / CMAS notifications may occur at any time. The terminal in the RRC IDLE / INACTIVE state wakes up periodically according to the paging DRX cycle to monitor paging at its own PO position, and can avoid monitoring the PDCCH at other times to save the power consumption of the terminal. Optional values of the DRX cycle: {320, 640, 1280, 2560} ms.

[0047] For an RRC IDLE UE, the paging DRX cycle = min{non-access stratum NAS UE specific DRX cycle, cell-specific DRX cycle}.

[0048] For an RRC INACTIVE UE, the paging DRX cycle = min{NAS UE specific DRX cycle, RRC UE-specific DRX cycle, cell specific DRX cycle}.

[0049] In this article, the cell-common monitoring period cell specific DTX cycle is the DRX cycle broadcast by the cell, which is called the default DRX cycle in the existing protocol.

[0050] 3. System Message Modification Period: The update of system messages is executed according to the modification period. That is, within a system message modification period X, if the terminal receives a system message change notification through a short message, it will obtain the updated system message within the system message modification period X+1. Considering that ETWS / CMAS belongs to public safety, when the terminal receives an ETWS / CMAS notification, the terminal can immediately attempt to obtain the system information related to ETWS / CMAS within the current period X.

[0051] 4. Core Network (CN) Paging and Radio Access Network (RAN) Paging:

[0052] When the terminal is in the RRC IDLE state, after the downlink service reaches the core network, the core network will initiate CN paging within the registration area.

[0053] When the terminal is in the RRC INACTIVE state, when the downlink service or NAS signaling reaches the anchor base station, the anchor base station will initiate RAN paging.

[0054] Next, in combination with the accompanying drawings, the paging monitoring method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0055] Figure 2 It is a schematic flowchart of the paging monitoring method provided by the embodiments of the present application. This method is applied to a terminal and includes:

[0056] Step 201, the terminal receives configuration information;

[0057] Specifically, in the embodiments of the present application, the terminal receives the configuration information sent by the network side device. Optionally, the configuration information may include the UE specific monitoring period and / or the cell specific monitoring period. As an implementation manner, the UE specific monitoring period is the UE specific DRX period, and the cell specific monitoring period is the cell specific DRX period. Here, the DRX period refers to the DRX period on the terminal side. As another implementation manner, the UE specific monitoring period is the monitoring period dedicated to paging messages (the paging message monitoring period is default UE specific), and the cell specific monitoring period is the cell specific DRX period.

[0058] In the embodiments of the present application, it is not restricted that the dedicated listening period of the terminal and the common listening period of the cell are obtained in the same configuration message. As an implementation manner, the network side may send the dedicated listening period of the terminal and the common listening period of the cell in the same message. As another implementation manner, the network sends the dedicated listening period of the terminal and the common listening period of the cell at different times through different messages. For example, the network sends the common listening period of the cell through broadcast and sends the dedicated listening period of the terminal through dedicated signaling.

[0059] Step 202: The terminal determines at least one of the listening period of the paging message, the listening period of the first type of system message change notification, and the listening period of the first information according to the configuration information; wherein, the first information includes at least one of the following: the second type of system message change notification, the public warning system PWS notification.

[0060] Specifically, after receiving the configuration information, the terminal can determine at least one of the listening period of the paging message, the listening period of the first type of system message change notification, and the listening period of the first information according to the configuration information. Optionally, the first information is information sensitive to latency, and the first information includes at least one of the following: the second type of system message change notification that is sensitive to latency or needs to be sent frequently, the public warning system PWS notification. Optionally, in the embodiments of the present application, the listening periods of the paging message, the first type of system message change notification, and / or the first information can be defined respectively, so that the listening period of the paging message can be defined according to the actual requirements of the terminal for services, and a shorter listening period is defined for the information sensitive to latency, thereby effectively avoiding the problem of increased power consumption of the terminal caused by intensive listening to paging messages in the case where the listening periods of both the paging message and the short message in the prior art are the minimum value min{dedicated listening period of the terminal, common listening period of the cell}, and effectively reducing the power consumption of the terminal.

[0061] For the method of the above embodiment, the terminal determines at least one of the listening period of the paging message, the listening period of the first type of system message change notification, and the listening period of the first information according to the configuration information, thereby realizing that the terminal defines the listening periods of various types of information according to the actual service requirements. While meeting the actual listening requirements of the terminal for various types of information, it can also effectively reduce the power consumption of the terminal and avoid the problem of increased terminal power consumption caused by intensive listening to paging messages in the case where the listening periods of both the paging message and the short message in the prior art are the minimum value min{dedicated listening period of the terminal, common listening period of the cell}.

[0062] Optionally, the configuration information includes the common listening period of the cell and / or the dedicated listening period of the terminal.

[0063] Specifically, the configuration information in the embodiments of the present application may include a cell-common monitoring period and / or a terminal-specific monitoring period. Optionally, the cell-common monitoring period and the terminal-specific monitoring period in the configuration information may be configured for different network devices. After receiving the configuration information, the terminal can use the cell-common monitoring period and / or the terminal-specific monitoring period to accurately and quickly determine the monitoring periods of various types of information, so that a shorter monitoring period is defined for information sensitive to latency, and the monitoring period of the paging message can be defined according to the actual needs of the terminal, thereby achieving the effect of saving the power consumption of the terminal while meeting the actual monitoring needs of the terminal for various types of information.

[0064] Optionally, the terminal determines at least one of the monitoring period of the paging message, the monitoring period of the first type of system message change notification, and the monitoring period of the first information according to the configuration information, including:

[0065] The terminal determines the cell-common monitoring period as the monitoring period of the first type of system message change notification and / or the monitoring period of the first information.

[0066] Specifically, when the configuration information sent by the network-side device to the terminal includes the cell-common monitoring period, the terminal determines the cell-common monitoring period as the monitoring period of the first type of system message change notification and / or the monitoring period of the first information. Furthermore, the terminal can then monitor the first type of system message change notification and / or the first information according to the cell-common monitoring period, so as to implement monitoring of the paging message and information sensitive to latency based on different monitoring periods respectively, thereby effectively reducing the power consumption of the terminal while meeting the actual service requirements of the terminal. As an implementation manner, the terminal monitors a short message according to the cell-common monitoring period.

[0067] Optionally, the terminal determines at least one of the monitoring period of the paging message, the monitoring period of the first type of system message change notification, and the monitoring period of the first information according to the configuration information, including:

[0068] When the configuration information includes the terminal-specific monitoring period, the terminal determines the terminal-specific monitoring period as the monitoring period of the paging message;

[0069] When the configuration information includes the cell-common monitoring period and does not include the terminal-specific monitoring period, the terminal determines the cell-common monitoring period as the monitoring period of the paging message.

[0070] Specifically, when the configuration information sent by the network - side device to the terminal includes the dedicated listening period of the terminal, the terminal determines the dedicated listening period of the terminal as the listening period for paging messages. When the configuration information sent by the network - side device to the terminal includes the cell - common listening period and does not include the dedicated listening period of the terminal, the terminal determines the cell - common listening period as the listening period for paging messages. Thus, the terminal accurately and flexibly determines the listening period for paging messages according to the cell - common listening period and / or the dedicated listening period in the configuration information, effectively meeting the actual service requirements of the terminal and avoiding the problem of increased power consumption of the terminal caused by intensive listening for paging messages.

[0071] Optionally, the terminal determines the dedicated listening period of the terminal as the listening period for paging messages, including:

[0072] When the terminal is in the Radio Resource Control (RRC) idle state and the dedicated listening period of the terminal includes the dedicated listening period configured by the core network element, the terminal determines the dedicated listening period configured by the core network element as the listening period for paging messages.

[0073] Specifically, for a terminal in the RRC idle state, if the terminal is configured with a dedicated listening period by the core network through dedicated signaling (such as NAS), that is, in the case of the dedicated listening period of the terminal, the terminal listens for paging messages according to the dedicated listening period of the terminal; otherwise, the terminal listens for paging messages according to the cell - common listening period. Thus, the paging messages and the information sensitive to latency are listened to based on different listening periods respectively, effectively reducing the power consumption of the terminal while meeting the actual service requirements of the terminal and avoiding the problem of increased power consumption of the terminal caused by intensive listening for paging messages.

[0074] Optionally, the terminal determines the dedicated listening period of the terminal as the listening period for paging messages, including:

[0075] When the terminal is in the RRC inactive state and the dedicated listening period of the terminal includes the dedicated listening period configured by the core network element and the dedicated listening period configured by the access network element, the terminal determines the minimum of the dedicated listening period configured by the core network element and the dedicated listening period configured by the access network element as the listening period for paging messages; or,

[0076] When the terminal is in the RRC inactive state and the dedicated listening period of the terminal includes the dedicated listening period configured by the core network element and does not include the dedicated listening period configured by the access network element, the terminal determines the dedicated listening period configured by the core network element as the listening period for paging messages; or,

[0077] When the terminal is in the RRC inactive state and the dedicated monitoring period of the terminal includes the dedicated monitoring period of the terminal configured by the access network element and does not include the dedicated monitoring period of the terminal configured by the core network element, the terminal determines the dedicated monitoring period of the terminal configured by the access network element as the monitoring period of the paging message.

[0078] As an implementation manner, when the terminal transitions from the RRC inactive state to the RRC idle state, if the terminal has both the dedicated monitoring period of the terminal configured by the core network element and the dedicated monitoring period of the terminal configured by the access network element at this time, the terminal uses the dedicated monitoring period of the terminal configured by the core network element as the monitoring period of the paging message.

[0079] Specifically, when the terminal is in the RRC inactive state and the terminal receives both the dedicated monitoring period of the terminal configured by the core network element and the dedicated monitoring period of the terminal configured by the access network element, the terminal determines the smaller of the dedicated monitoring period of the terminal configured by the core network element and the dedicated monitoring period of the terminal configured by the access network element as the monitoring period of the paging message. When the terminal is in the RRC inactive state and the terminal receives the dedicated monitoring period of the terminal configured by the core network element but does not receive the dedicated monitoring period of the terminal configured by the access network element, the terminal determines the dedicated monitoring period of the terminal configured by the core network element as the monitoring period of the paging message. When the terminal is in the RRC inactive state and the terminal receives the dedicated monitoring period of the terminal configured by the access network element but does not receive the dedicated monitoring period of the terminal configured by the core network element, the terminal determines the dedicated monitoring period of the terminal configured by the access network element as the monitoring period of the paging message. This enables the terminal to accurately and flexibly determine the monitoring period of the paging message according to the content of the configuration information, and implement monitoring of the paging message and information sensitive to delay based on different monitoring periods respectively, effectively reducing the power consumption of the terminal.

[0080] Optionally, when the terminal is in the RRC inactive state and the configuration information includes the dedicated monitoring period of the terminal configured by the access network element and does not include the dedicated monitoring period of the terminal configured by the core network element, if the protocol stipulates that the terminal is configured with the dedicated monitoring period of the terminal by the access network element and the dedicated monitoring period of the terminal configured by the core network element is a mandatory configuration, then the terminal considers that the configuration does not conform to the protocol regulations. At this time, the terminal can perform some exception handling, such as reporting configuration exceptions to the network side, or the terminal autonomously enters the RRC idle state.

[0081] It should be noted that during the RRC INACTIVE state of the terminal, if the RAN paging initiated by the anchor base station fails or the number of failures reaches a certain threshold, the network will fallback to CN paging. If the CN does not know the dedicated monitoring period of the terminal when paging, there is a risk that the terminal may miss the paging. Therefore, the anchor base station needs to send the configured dedicated monitoring period of the terminal to the core network. Then the core network will page the terminal based on the dedicated monitoring period configured by the anchor base station. Another possible way is to not allow this situation to occur, that is, when the access network element configures the dedicated monitoring period of the terminal, the dedicated monitoring period configured by the core network element must also be configured.

[0082] After determining the monitoring period of the paging message, the monitoring period of the first type of system message change notification, and / or the monitoring period of the first information, the method further includes at least one of the following:

[0083] During the period when the terminal monitors the first type of system message change notification and / or the first information but does not monitor the paging message, the terminal selects any paging occasion PO to monitor the first type of system message change notification and / or the first information;

[0084] During the period when the terminal monitors the first type of system message change notification and / or the first information but does not monitor the paging message, the terminal receives the first type of system message change notification and / or the first information according to the synchronization signal block SSB;

[0085] During the period when the terminal monitors the first type of system message change notification and / or the first information but does not monitor the paging message, after detecting the first wake-up signal WUS, the terminal monitors the first type of system message change notification and / or the first information; the first WUS is used to wake up the terminal to monitor the first type of system message change notification and / or the first information.

[0086] It should be noted that in the embodiments of the present application, examples of monitoring information according to a period and monitoring information within a certain period are as follows. The terminal monitors the paging message according to the first period, and the first period is 1.28 s. Then the terminal monitors the paging message at its own PO every 1.28 s. A certain period refers to a time range within a certain 1.28 s. If the total time is divided into N 1.28 s, the total time includes period 1, period 2, period 3,..., period N.

[0087] Specifically, if the monitoring period common to the cell is less than the monitoring period specific to the terminal, after the terminal determines the monitoring period of the paging message, the monitoring period of the first type of system message change notification, and / or the monitoring period of the first information, there will be some periods during which the terminal needs to monitor the paging message, the first type of system message change notification, and the first information, and in some other periods, the terminal only monitors the first type of system message change notification and / or the first information. Optionally, during the periods when the terminal needs to monitor the paging message, the first type of system message change notification, and the first information, the terminal monitors the paging message, the first type of system message change notification, and the first information based on its own paging occasion (PO). Optionally, during the periods when the terminal only monitors the first type of system message change notification and / or the first information, the terminal can flexibly select the monitoring method for the first type of system message change notification and / or the first information, so as to monitor the first type of system message change notification and / or the first information in a lower power consumption manner. Optionally, the terminal can select any paging occasion (PO) to monitor the first type of system message change notification and / or the first information. For example, when the SSB transmission period is relatively large, the terminal can select to monitor the first type of system message change notification and / or the first information at the PO position closest to the measured SSB. The terminal can also receive the first type of system message change notification and / or the first information according to the synchronization signal block (SSB), so that the terminal does not need to receive the PO after receiving the SSB, which helps to further reduce the power consumption of the terminal. The terminal can also use a low-power receiver to receive the Wake up signal (WUS) and then monitor the first type of system message change notification and / or the first information. The power consumption is much lower than that of receiving the PO, so as to monitor the first type of system message change notification and / or the first information with lower power.

[0088] For example, as Figure 3 shown, in the embodiment of the present application, it is assumed that the NAS UE specific DRX period configured for the terminal is 2.56 s, and the cell specific DRX period broadcast by the currently camped cell is 1.28 s. Taking 1.28 s as a period, the terminal measures 3 SSBs before the PO in every odd 1.28 s period, and executes the measurement of 1 SSB before the PO in every even 1.28 s period, so as to effectively reduce the power consumption of the terminal.

[0089] In the method of the above embodiments, during the period when the terminal monitors the first type of system message change notification and / or the first information but does not monitor the paging message, the terminal can select any paging occasion PO to monitor the first type of system message change notification and / or the first information, or can receive the first type of system message change notification and / or the first information according to the synchronization signal block SSB, or can also monitor the first type of system message change notification and / or the first information after detecting the first wake-up signal WUS. Thus, while enabling the terminal to flexibly select the monitoring manner of the first type of system message change notification and / or the first information, the terminal can also monitor the first type of system message change notification and / or the first information with lower power, achieving the effect of energy saving for the terminal.

[0090] Optionally, receiving the first type of system message change notification and / or the first information according to the synchronization signal block SSB includes at least one of the following:

[0091] Receiving the first type of system message change notification and / or the first information according to the first target field in the master information block MIB of the SSB; the first target field is used to indicate the first type of system message change notification and / or the first information, or, the first target field is used to indicate whether the terminal needs to receive the first type of system message change notification and / or the first information;

[0092] Receiving the first type of system message change notification and / or the first information according to the synchronization reference signal in the SSB; the synchronization reference signal carries the first type of system message change notification and / or the first information;

[0093] Receiving the first type of system message change notification and / or the first information according to the physical layer information in the SSB; the physical layer information carries the first type of system message change notification and / or the first information.

[0094] Specifically, the first type of system message change notification and / or the first information can be carried in the SSB sent by the network side device, so that the terminal can receive the first type of system message change notification and / or the first information through the SSB. Optionally, the network side device can carry the first type of system message change notification and / or the first information in the synchronization reference signal or the physical layer information of the SSB, so that the terminal does not need to receive the PO after receiving the SSB, which helps to further reduce the power consumption of the terminal. Optionally, the terminal can select any SSB to receive the first type of system message change notification and / or the first information during the period when it only monitors the first type of system message change notification and / or the first information.

[0095] Optionally, the network side device may also indicate the first type of system message change notification and / or the first information in an existing field in the SSB, or indicate whether the terminal needs to receive the first type of system message change notification and / or the first information; the network side device may also add a new field in the SSB specifically for indicating the first type of system message change notification and / or the first information, or indicating whether the terminal needs to receive the first type of system message change notification and / or the first information, so that the terminal can receive the first type of system message change notification and / or the first information in multiple ways according to the SSB, improving the flexibility of the terminal to receive the first type of system message change notification and / or the first information.

[0096] For example, the first type of system message change notification and / or the first information is carried by the Master Information Block (MIB) of the SSB. After receiving the SSB, the terminal does not need to receive the PO anymore, which helps to further reduce the power consumption of the terminal. Optionally, the existing MIB can be directly extended. For example, 2 bits are added to the existing MIB, which are respectively used to indicate the first type of system message change notification and the first information. Another way is to reuse the fields in the existing MIB. For example, the existing intraFreqReselection field is reused. As an implementation, if the current cell is barred, the terminal needs to determine whether it is allowed to perform intra-frequency reselection according to the intra-frequency reselection information element (IE) in the MIB. When this cell is not barred, the terminal directly camps on this cell. At this time, the intra-frequency reselection IE has no additional meaning for the terminal, so this IE can be reused. Optionally, when the cell is not barred, if the value of the intra-frequency reselection field is 1, it means that the terminal needs to receive the PO to obtain the first type of system message change notification and / or the first information. If the value of the intra-frequency reselection field is 0, it means that there is no first type of system message change notification and / or the first information, and the terminal does not need to monitor the corresponding PO during this period. That is, the network side device can use the existing intra-frequency reselection field as the first target field to indicate the first type of system message change notification and / or the first information, or indicate whether the terminal needs to receive the first type of system message change notification and / or the first information, realizing the accurate indication of the terminal's monitoring period based on the existing field and being easier to implement.

[0097] In the method of the above embodiment, the first type of system message change notification and / or the first information can be carried in the SSB sent by the network side device in multiple ways, so that the terminal can flexibly obtain the first type of system message change notification and / or the first information, improving the flexibility.

[0098] Optionally, before detecting the first WUS, it further includes:

[0099] The terminal receives the first WUS configuration information sent by the network-side device; the first WUS configuration information includes at least one of the following: the listening position of the first WUS, the repetition period of the first WUS, and the duration of the first WUS.

[0100] Specifically, during the period when the terminal only listens to the change notification of the first type of system message and / or the first information, the terminal can listen to the first WUS dedicated to the change notification of the first type of system message and / or the first information. After receiving the first WUS, the terminal then listens to the change notification of the first type of system message and / or the first information, thereby reducing the power consumption of the terminal.

[0101] Optionally, before listening to the first WUS, the terminal can receive the first WUS configuration information sent by the network-side device. The first WUS configuration information includes the listening position, repetition period, and duration of the first WUS, so that the terminal can accurately and quickly listen to the first WUS. Then, after listening to the first WUS according to the first WUS configuration information, it can also achieve the listening to the change notification of the first type of system message and / or the first information, achieving the effect of reducing the power consumption of the terminal.

[0102] Optionally, the network-side device can carry the first WUS configuration information in the broadcast message. Optionally, the network-side device can also send the first WUS configuration information using dedicated signaling. For example, when the network releases the terminal, the first WUS is configured, and the first WUS configuration information is valid within a certain area.

[0103] Optionally, in the first WUS configuration information, the listening positions of the first WUS of each terminal corresponding to the network-side device are the same, that is, all terminals have the same listening position for the first WUS. As an implementation manner, the first WUS is configured as a cell-specific configuration.

[0104] Optionally, in the first WUS configuration information, the listening position of the terminal for the first WUS can also be associated with the terminal's own PO. For example, there is a preset time-domain interval between the listening position of the terminal for the first WUS and the terminal's own PO, or the terminal can optionally choose any PO to listen to the first WUS.

[0105] In the method of the above embodiment, the network-side device sends the first WUS configuration information to the terminal, so that the terminal can accurately determine the listening mode of the first WUS based on the first WUS configuration information. Then, after receiving the first WUS, it can also obtain the change notification of the first type of system message and / or the first information, achieving the effect of listening to the change notification of the first type of system message and / or the first information in a lower-power manner, effectively reducing the power consumption of the terminal.

[0106] Optionally, the configuration information includes a first monitoring period dedicated to determining the monitoring period of the first information. The terminal determines at least one of the monitoring period of the paging message, the monitoring period of the first type of system message change notification, and the monitoring period of the first information according to the configuration information, including:

[0107] The terminal determines the monitoring period of the first information according to the first monitoring period.

[0108] Specifically, in the embodiments of the present application, the first information is a second type of system message change notification and / or a Public Warning System (PWS) notification that is sensitive to latency and needs to be sent frequently. Therefore, by defining a separate monitoring period, the power consumption of the terminal can be reduced. Optionally, the configuration information sent by the network-side device includes a first monitoring period for monitoring latency-sensitive information. After receiving the first monitoring period in the configuration information, the terminal can use the first monitoring period as the monitoring period of the first information, so that the first information sensitive to latency can define a shorter monitoring period. The monitoring period of the paging message can be defined according to the actual needs of the terminal, or the monitoring period of the paging message can still be based on the minimum value min{the monitoring period dedicated to the terminal, the monitoring period common to the cell}, thereby effectively avoiding the problem of increased power consumption of the terminal caused by intensive monitoring of paging messages in the prior art when the monitoring periods of both the paging message and the short message are the minimum value min{the monitoring period dedicated to the terminal, the monitoring period common to the cell}, and effectively reducing the power consumption of the terminal.

[0109] For example, the terminal receives the monitoring period dedicated to the terminal for receiving paging messages; the terminal receives the monitoring period common to the cell through a broadcast message for monitoring the monitoring period of the first type of system message change notification; the terminal receives the first monitoring period for the monitoring period of the first information. The terminal monitors the paging message, the monitoring period of the first type of system message change notification, and the first information in the following manner:

[0110] During the period when it is necessary to monitor paging messages, the terminal monitors the paging message, the first type of system message change notification, and the first information according to its own PO.

[0111] During the period when it is necessary to monitor system message changes, the terminal monitors the first type of system message change notification and the first information according to its own PO or optionally selects a PO.

[0112] During the period when only the first information needs to be monitored, the terminal obtains the first information through WUS.

[0113] For another example, the terminal receives a dedicated listening period for the terminal, a cell-common listening period, and a first listening period. The terminal listens for the first information according to the first listening period, and listens for paging messages and type-1 system message change notifications according to min{the dedicated listening period for the terminal, the cell-common listening period}.

[0114] In the method of the above embodiment, a listening period is separately defined for the first information that is delay-sensitive and needs to be frequently sent, so that the terminal can define the listening periods of various types of information according to actual service requirements. While meeting the actual listening requirements of the terminal for various types of information, it can also effectively save the power of the terminal, and avoid the problem of increased power consumption of the terminal caused by intensive listening for paging messages in the case where the listening periods for listening for paging messages and short messages in the prior art are both min{the dedicated listening period for the terminal, the cell-common listening period}.

[0115] Optionally, after determining the listening period of the first information, at least one of the following is further included:

[0116] During the listening period of the first information, the terminal listens for a second WUS; the second WUS carries the first information;

[0117] During the listening period of the first information, the terminal listens for the first information according to the SSB.

[0118] Specifically, during the listening period of the first information, the terminal can flexibly select the listening method of the first information, so as to realize listening for the first information in a lower power consumption manner. Optionally, the terminal can receive the first information according to the synchronization signal block SSB. The terminal can also use a low-power receiver to receive the second WUS and then listen for the first information, and the power consumed is much lower than the power consumption of receiving the PO, so as to realize listening for type-1 system message change notifications and / or the first information with lower power, effectively reducing the power consumption of the terminal. Optionally, the network-side device can send the first information in the existing manner, but additionally support carrying the first information in the SSB / WUS.

[0119] As an implementation manner, after the terminal listens for the second WUS, it does not need to further listen for the first information, that is to say, the second WUS directly indicates the first information. For example, the second WUS is a WUS signal dedicated to the first information. When the terminal listens for the second WUS, it is equivalent to receiving the first information, that is, the terminal can immediately obtain the system information related to the first information. When the terminal does not listen for the second WUS, it means that there is no change in the system message that is delay-sensitive at this time, and the terminal does not need to obtain the ETWS / CMAS system information.

[0120] Optionally, before the terminal listens for the second WUS, the following is further included:

[0121] The terminal receives the second WUS configuration information sent by the network-side device; the second WUS configuration information includes at least one of the following: the listening position of the second WUS, the repetition period of the second WUS, and the duration of the second WUS.

[0122] Specifically, within the period of listening to the first information, the terminal can listen to the second WUS dedicated to the first information. After receiving the second WUS, the terminal then listens to the first information, thereby reducing the power consumption of the terminal. Optionally, before listening to the second WUS, the terminal can receive the second WUS configuration information sent by the network-side device. The second WUS configuration information includes the listening position, repetition period, and duration of the second WUS, so that the terminal can accurately and quickly listen to the second WUS. Then, after listening to the second WUS according to the second WUS configuration information, the terminal can also listen to the first information, achieving the effect of reducing the power consumption of the terminal.

[0123] Optionally, the network-side device can carry the second WUS configuration information in a broadcast message.

[0124] Optionally, in the second WUS configuration information, the listening positions of the second WUS of each terminal corresponding to the network-side device are the same, that is, all terminals have the same listening position for the second WUS. Optionally, the second WUS configuration is cell specific.

[0125] Optionally, in the second WUS configuration information, the listening position of the terminal for the second WUS can also be associated with the terminal's own PO. For example, there is a preset time-domain interval between the listening position of the terminal for the second WUS and the terminal's own PO, or the terminal can optionally choose any PO to listen to the second WUS.

[0126] Optionally, the terminal receives the first information according to the SSB, including at least one of the following:

[0127] Receiving the first information according to the second target field in the master information block MIB of the SSB; the second target field carries the first information;

[0128] Receiving the first information according to the synchronization reference signal in the SSB; the synchronization reference signal carries the first information;

[0129] Receiving the first information according to the physical layer information in the SSB; the physical layer information carries the first information.

[0130] Specifically, the first information can be carried in the SSB sent by the network-side device, so that the terminal can receive the first information through the SSB. Optionally, the network-side device can carry the first information in the synchronization reference signal or physical layer information of the SSB, so that the terminal does not need to receive the PO after receiving the SSB, which helps to further reduce the power consumption of the terminal.

[0131] Optionally, the network-side device may indicate the first information in an existing field in the SSB, or the network-side device may also add a new field in the SSB specifically for indicating the first information, so that the terminal can receive the first information in multiple ways based on the SSB, improving the flexibility of the terminal to receive the first information.

[0132] For example, the first information is carried by the MIB of the SSB. After receiving the SSB, the terminal does not need to receive the PO anymore, which helps to further reduce the power consumption of the terminal. Optionally, the MIB can be directly extended to carry the corresponding information; for example, adding 1 field to represent the first information; or carrying it through the synchronization reference signal (for example, the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the corresponding Demodulation Reference Signal (DMRS)), or carrying it through the physical layer information.

[0133] Optionally, the IEs in the existing MIB can also be reused. As an implementation, if the current cell is barred, the terminal can determine whether it is allowed to perform intra-frequency reselection according to the intra-frequency reselection IE in the MIB. When this cell is not barred, the terminal directly camps on this cell. At this time, the intra-frequency reselection IE has no additional meaning for the terminal, so the intra-frequency reselection IE can be reused to indicate the first information.

[0134] For example, reusing the IEs in the existing MIB. In Embodiment 1, when the cell barring parameter cellBarred = disabled "barred" and the intra-frequency reselection information unit intraFreqReselection IE = not allowed (value = 0), for RRC IDLE / INACTIVE UEs, the terminal considers that this cell is barred and also considers that intra-frequency reselection is not allowed.

[0135] In Embodiment 2, the cell barring parameter cellBarred = not barred "not barred" and the intra-frequency reselection information unit intraFreqReselection IE = indication of the first information ETWS / CMAS indication (value = 0). For RRC IDLE / INACTIVE UEs, the terminal camps on this cell and receives the first information according to the intra-frequency reselection information unit; when the value of the intra-frequency reselection information unit is 0, it is determined that there is no need to obtain the ETWS / CMAS system information.

[0136] In the method of the above embodiments, the first information can be carried in the SSB sent by the network-side device in various ways, so that the terminal can flexibly obtain the first information, improving flexibility.

[0137] As an implementation manner, if the terminal has the ability to receive the first information, the terminal listens for the first information and the change of the first type of system message based on the first listening period. If the terminal does not have the ability to receive the first information, the terminal listens for the first information and the change of the first type of system message based on the cell-common listening period.

While meeting the actual listening requirements of the terminal for various types of information, it can also effectively reduce the power consumption of the terminal, avoiding the problem of increased power consumption of the terminal caused by intensive listening of paging messages in the prior art where the listening periods of both the paging message and the short message are the minimum value min{the terminal-specific listening period, the cell-common listening period}.
