In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of business in future life, the ^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

On the one hand, eMBB still aims at users obtaining multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized, and detailed analysis must be combined with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

In the early deployment of NR, it is difficult to obtain complete NR coverage, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large number of LTE deployments are below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, while the coverage of high frequency bands is limited and the signal fades quickly. At the same time, in order to protect mobile operators' early investment in LTE, a tight interworking working mode between LTE and NR is proposed.

RRC state

In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new Radio Resource Control (RRC) state, that is, RRC_INACTIVE state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,

1) RRC_IDLE state (referred to as idle (idle) state): Mobility is cell selection and reselection based on terminal equipment, paging is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no terminal device context on the base station side, and there is no RRC connection.

2) RRC_CONNECTED state (connected state for short): there is an RRC connection, and there is a terminal device context at the base station side and the terminal device side. The network side knows the location of the terminal equipment at the specific cell level. Mobility is mobility controlled by the network side. Unicast data can be transmitted between the terminal equipment and the base station.

3) RRC_INACTIVE state (referred to as inactive (inactive) state): Mobility is cell selection and reselection based on terminal equipment, there is a connection between CN-NR, the context of the terminal equipment exists on a certain base station, and paging is triggered by RAN , the RAN-based paging area is managed by the RAN, and the network side knows the location of the terminal device based on the RAN-based paging area level.

MBMS

MBMS is a technology that transmits data from one data source to multiple terminal devices by sharing network resources. This technology can effectively use network resources while providing multimedia services, and realize broadcasting of multimedia services at a higher rate (such as 256kbps) and multicast.

Due to the low spectrum efficiency of MBMS, it is not enough to effectively carry and support the operation of mobile TV services. Therefore, in LTE, 3GPP clearly proposed to enhance the ability to support downlink high-speed MBMS services, and determined the design requirements for the physical layer and air interface.

3GPP R9 introduces evolved MBMS (evolved MBMS, eMBMS) into LTE. eMBMS proposes the concept of Single Frequency Network (SFN), that is, Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN). MBSFN uses a unified frequency to transmit service data in all cells at the same time, but To ensure the synchronization between cells. This method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the spectrum efficiency will also be greatly improved accordingly. eMBMS implements broadcast and multicast of services based on the IP multicast protocol.

In LTE or LTE-Advanced (LTE-Advanced, LTE-A), MBMS only has a broadcast bearer mode, but no multicast bearer mode. In addition, the reception of MBMS service is applicable to terminal equipments in idle state or connected state.

3GPP R13 introduced the concept of Single Cell Point To Multiploint (SC-PTM), and SC-PTM is based on the MBMS network architecture.

MBMS introduces new logical channels, including Single Cell-Multicast Control Channel (Single Cell-Multicast Control Channel, SC-MCCH) and Single Cell-Multicast Transport Channel (Single Cell-Multicast Transport Channel, SC-MTCH). SC-MCCH and SC-MTCH are mapped to the downlink shared channel (Downlink-Shared Channel, DL-SCH), and further, DL-SCH is mapped to the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), wherein, SC - MCCH and SC-MTCH belong to logical channels, DL-SCH belongs to transport channels, and PDSCH belongs to physical channels. SC-MCCH and SC-MTCH do not support Hybrid Automatic Repeat reQuest (HARQ) operation.

MBMS introduces a new system information block (System Information Block, SIB) type, namely SIB20. Specifically, SIB20 is used to transmit SC-MCCH configuration information, and one cell has only one SC-MCCH. The SC-MCCH configuration information includes: SC-MCCH modification period, SC-MCCH repetition period, and information such as radio frames and subframes for scheduling SC-MCCH. Further, 1) the boundary of the modification period of SC-MCCH satisfies SFN mod m=0, wherein, SFN represents the system frame number of the boundary, and m is the modification period (ie sc-mcch-ModificationPeriod) of the SC-MCCH configured in SIB20. 2) Scheduling the wireless frame of SC-MCCH satisfies: SFN mod mcch-RepetitionPeriod=mcch-Offset, wherein, SFN represents the system frame number of the wireless frame, mcch-RepetitionPeriod represents the repetition period of SC-MCCH, and mcch-Offset represents SC-MCCH offset. 3) The subframe for scheduling the SC-MCCH is indicated by sc-mcch-Subframe.

The SC-MCCH is scheduled through a Physical Downlink Control Channel (PDCCH). On the one hand, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), that is, a single cell RNTI (Single Cell RNTI, SC-RNTI) is introduced to identify the PDCCH (such as SC-MCCH PDCCH) used to schedule the SC-MCCH, Optionally, the fixed value of SC-RNTI is FFFC. On the other hand, a new RNTI is introduced, that is, a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) to identify the PDCCH used to indicate the change notification of the SC-MCCH (such as notifying the PDCCH). Optionally, the SC The fixed value of -N-RNTI is FFFB; further, one of the 8 bits (bits) of DCI 1C can be used to indicate the change notification. In LTE, SC-PTM configuration information is based on SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH, and SC-MTCH is used to transmit service data.

Specifically, the SC-MCCH only transmits one message (that is, SCPTMConfiguration), which is used to configure configuration information of the SC-PTM. The configuration information of SC-PTM includes: temporary mobile group identity (Temporary Mobile Group Identity, TMGI), session identification (seession id), group RNTI (Group RNTI, G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information And the SC-PTM service information of the neighboring cell, etc. It should be noted that SC-PTM in R13 does not support Robust Header Compression (Robust Header Compression, ROHC) function.

The downlink discontinuous reception of SC-PTM is controlled by the following parameters: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.

When [(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset is satisfied, start the timer onDurationTimerSCPTM;

When receiving downlink PDCCH scheduling, start the timer drx-InactivityTimerSCPTM;

The downlink SC-PTM service is received only when the timer onDurationTimerSCPTM or drx-InactivityTimerSCPTM is running.

SC-PTM business continuity adopts the concept of MBMS business continuity based on SIB15, that is, "SIB15+MBMSInterestIndication" mode. The service continuity of terminal equipment in idle state is based on the concept of frequency priority.

In the technical solution of the embodiment of the present application, a new SIB (called the first SIB) is defined, and the first SIB includes the configuration information of the first MCCH. Here, the first MCCH is the control channel of the MBMS service. In other words, the first SIB includes the configuration information of the first MCCH. One SIB is used to configure the configuration information of the NR MBMS control channel. Optionally, the NR MBMS control channel may also be called NR MCCH (that is, the first MCCH).

Further, the first MCCH is used to carry the first signaling. The embodiment of the present application does not limit the name of the first signaling. For example, the first signaling is signaling A, and the first signaling includes at least one first MTCH configuration information, here, the first MTCH is a traffic channel (also referred to as a data channel or a transmission channel) of the MBMS service, and the first MTCH is used to transmit MBMS service data (such as NR MBMS service data). In other words, the first MCCH is used to configure the configuration information of the traffic channel of NR MBMS. Optionally, the traffic channel of NR MBMS can also be called NR MTCH (that is, the first MTCH).

Specifically, the first signaling is used to configure an NR MBMS traffic channel, service information corresponding to the traffic channel, and scheduling information corresponding to the traffic channel. Further, optionally, the service information corresponding to the service channel, such as TMGI, session id and other identification information for identifying services. The scheduling information corresponding to the traffic channel, for example, the RNTI used when the MBMS service data corresponding to the traffic channel is scheduled, such as G-RNTI, DRX configuration information, and the like.

It should be noted that both the transmission of the first MCCH and the first MTCH are scheduled based on the PDCCH. Wherein, the RNTI used by the PDCCH for scheduling the first MCCH uses a network-wide unique identifier, that is, a fixed value. The RNTI used by the PDCCH for scheduling the first MTCH is configured through the first MCCH.

It should be noted that, in this embodiment of the present application, there is no restriction on naming of the first SIB, the first MCCH, and the first MTCH. For ease of description, the first SIB can also be referred to as the SIB for short, the first MCCH can also be referred to as the MCCH for short, and the first MTCH can also be referred to as the MTCH for short, and the PDCCH (ie, the MCCH PDCCH) configured to schedule the MCCH is configured by the SIB. ) and notify the PDCCH, wherein, the PDSCH (ie MCCH PDSCH) used to transmit the MCCH is scheduled by the DCI carried by the MCCH PDCCH. Further, configure M PDCCHs for scheduling MTCH (ie MTCH 1 PDCCH, MTCH 2 PDCCH, ..., MTCH M PDCCH) through MCCH, wherein, the DCI scheduling carried by MTCH n PDCCH is used to transmit the PDSCH of MTCH n (ie MTCH n PDSCH), n is an integer greater than or equal to 1 and less than or equal to M. MCCH and MTCH are mapped to DL-SCH, and further, DL-SCH is mapped to PDSCH, wherein MCCH and MTCH belong to logical channels, DL-SCH belongs to transport channel, and PDSCH belongs to physical channel.

It should be noted that although the foregoing solution is described using MBMS as an example, the description of "MBMS" may also be replaced with "MBS". The embodiment of the present application uses MBS as an example for description, and the description of "MBS" may also be replaced with "MBMS".

energy saving

In order to realize the energy saving of terminal equipment, NR energy saving enhancement introduces Wake Up Signal (WUS), which can also be referred to as energy saving signal or wake up signal for short. In standardization, the energy-saving wake-up signal is used in combination with the discontinuous reception (DRX) mechanism. The specific technical principle is that the terminal device receives the energy-saving wake-up signal before the DRX ON duration. As shown in Figure 2, when the terminal device has During data transmission, the energy-saving wake-up signal instructs the terminal device to monitor the PDCCH, that is, the energy-saving wake-up signal "wakes up" the terminal device to monitor the PDCCH during the DRX ON duration; otherwise, when the terminal device has no data transmission in a DRX cycle, the energy-saving wake-up signal indicates The terminal device does not monitor the PDCCH, that is, the energy-saving wake-up signal does not "wake up" the terminal device, and the terminal device does not need to monitor the PDCCH during the DRX ON Duration. Compared with the traditional DRX mechanism, when the terminal device has no data transmission, the terminal device can omit the PDCCH monitoring during the DRX ON duration, thereby realizing energy saving. The time before the DRX ON duration of the terminal device is called the DRX inactive time, and the time when the terminal device is in the DRX ON Duration is called the DRX active time.

In NR, paging is also periodically sent to the terminal device. The position where the terminal device monitors the paging DCI is the paging occasion (Paging Occasion, PO). For a terminal device, its associated PO position is related to its UE ID. The POs of different terminal devices are discretely distributed within the paging cycle, as shown in FIG. 3 .

In the NR system, many scenarios need to support multicast and broadcast business requirements, such as in the Internet of Vehicles and the Industrial Internet. So it is necessary to introduce multicast and broadcast MBS services in NR. It should be noted that the multicast-type MBS service refers to the MBS service transmitted in a multicast manner. The broadcast-type MBS service refers to the MBS service transmitted by broadcasting.

In the NR system, for the multicast type MBS service, the MBS service is sent to all terminal devices in a certain group. The terminal equipment receives the multicast type MBS service in the RRC connection state, and the terminal equipment can receive the multicast type MBS service data through the PTM mode or the PTP mode. Wherein, referring to FIG. 4 , the MBS service data in the PTM mode scrambles the corresponding scheduling information through the G-RNTI configured on the network side, and the MBS service data in the PTP mode scrambles the corresponding scheduling information through the C-RNTI.

For the multicast MBS service, after receiving the MBS service delivered by the core network from the shared tunnel (tunnel), the base station can deliver the MBS service to all terminal devices in a group through the air interface. Here, the base station may deliver the MBS service to all terminal devices in a group through PTP and/or PTM. For example: a group includes Terminal 1, Terminal 2, and Terminal 3. The base station can deliver the MBS service to Terminal 1 through PTP, deliver the MBS service to Terminal 2 through PTP, and deliver the MBS The service is delivered to terminal equipment 3; or, the base station can deliver the MBS service to terminal equipment 1 through PTP, and the MBS service can be delivered to terminal equipment 2 and terminal equipment 3 through PTM; or, the base station can deliver the MBS service to terminal equipment 3 through PTM. The MBS service is delivered to terminal device 1, terminal device 2 and terminal device 3. Referring to Figure 5, a shared GTP tunnel (Shared GTP tunnel) is used between the core network and the base station to transmit MBS services, that is, both the PTM MBS service and the PTP MBS service share the GTP tunnel. The base station delivers MBS service data to UE1 and UE2 in a PTM manner, and delivers MBS service data to UE3 in a PTP manner.

For the multicast MBS service, if there is no service data to send at present, the terminal equipment can temporarily leave the RRC connection state and return to the RRC idle state or RRC inactive state, thereby realizing the energy saving of the terminal equipment. When there is service data, the terminal device is awakened by sending a group notification to enter the RRC connection state to receive the MBS service in the multicast mode. Here, the group notification adopts a paging message, the DCI of the paging message (that is, the paging DCI) is scrambled by P-RNTI, and the network side sends the paging DCI and paging DCI for activating the MBS service on each PO of the cell. Paging message, the paging message identifies the activated target MBS service by carrying the MBS session identifier. In NR, the paging of multiple users corresponding to the same PO can be multiplexed in one paging message, so multiple users corresponding to a PO will listen to the paging message of the MBS service, even if some users do not participate in the MBS service , the paging message of the MBS service will also wake up these users, which will affect these users, such as causing these users to waste electricity. In addition, NR supports beam sweeping (beam sweeping) transmission, so a paging message will be transmitted in multiple copies in a cell, and the specific number depends on the number of synchronization signal blocks (SS/PBCH Block, SSB) actually transmitted by the cell. In this way, the paging message of the MBS service will have a high load, wasting radio resources. To this end, the following technical solutions of the embodiments of the present application are proposed.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. As optional solutions, the above related technologies may be combined with the technical solutions of the embodiments of the present application in any combination, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following content.

Fig. 6 is a schematic flow chart of the paging method provided by the embodiment of the present application. As shown in Fig. 6, the paging method includes the following steps:

Step 601: The network device sends a first signaling to the terminal device, and the terminal device receives the first signaling, where the first signaling is associated with a first paging message; wherein the first signaling carries first indication information, The first indication information is used by the terminal device to determine whether to monitor a first DCI and/or receive the first paging message, where the first DCI refers to a paging system used to schedule the first paging message DCI.

In some optional implementation manners, the network device is a base station.

In this embodiment of the present application, the first signaling is the first DCI or the first WUS. Here, the first DCI may also be called the paging DCI, and the first WUS may also be called the paging WUS.

It should be noted that the paging DCI is used to schedule paging messages, and the paging DCI is scrambled through the P-RNTI.

It should be noted that the paging WUS is associated with one or more paging occasions, the paging WUS is located before its associated paging occasion, and the paging WUS is used to indicate whether to monitor the paging DCI in its associated PO. As an example, a paging WUS is associated with a paging opportunity immediately after it, and there is a paging WUS before each PO, and the paging WUS is used to indicate whether to monitor the paging DCI or Receive paging messages, so as to achieve the purpose of power saving of terminal equipment.

The technical solutions of the embodiments of the present application are illustrated below in conjunction with specific application examples.

Application example one

In this example, the network device indicates the paging type of the paging message to the terminal device through the paging DCI.

Specifically, the paging DCI carries first information, and the first information is used to indicate that the paging type of the paging message is one of the following: MBS paging only, Unicast paging only, MBS paging and unicast paging.

Wherein, if the first information indicates that the paging type of the paging message is MBS paging only, then the paging message only carries the MBS session identifier. If the first information indicates that the paging type of the paging message is Unicast paging only, then the paging message only carries the terminal equipment (ie UE ID). As an example, the UE ID can be 5G S-TMSI, I-RNTI, etc. If the first information indicates that the paging type of the paging message is MBS paging and unicast paging, then the paging message carries the MBS session identifier and the terminal equipment (ie UE ID).

In this example, for a terminal device that is not configured with the MBS service or does not support the MBS service, if the first information in the paging DCI indicates that the paging type of the paging message is MBS only paging, the terminal device does not receive the paging message .

In the above solution, the paging type of the paging message can be indicated by the value of the first information, for example, the first information is 2-bit information, and the value of the 2-bit information can be 00, 01, 10, 11. Some or all of the values indicate the paging type of the paging message.

Application example two

In this example, the network device indicates to the terminal device the MBS service that triggers the paging message through the paging DCI.

Specifically, the paging DCI carries second information, and the second information is a first bitmap (bitmap), and each bit in the first bitmap corresponds to an MBS session identifier or an MBS index of an MBS service; The value of the bit is used to indicate whether the MBS service corresponding to the bit is activated and/or whether a paging message is triggered. As an example, the value of a bit is 1 (or 0) to indicate that the MBS service corresponding to the bit is activated and/or a paging message is triggered, and the value of a bit is 0 (or 1) is used to indicate that the The MBS service corresponding to the bit is not activated and/or the paging message is not triggered.

In the above solution, if the terminal device determines based on the first bitmap that the first MBS service joined by the terminal device is activated and/or a paging message is triggered, then the terminal device determines to receive the paging message; if The terminal device determines, based on the first bitmap, that the first MBS service joined by the terminal device is not activated and/or does not trigger a paging message, then the terminal device determines not to receive a paging message.

Further, if the terminal device determines to receive the paging message, the terminal device initiates an RRC connection establishment process or an RRC connection recovery process, and receives the service triggered by the paging message after the RRC connection is established or the RRC connection is restored.

As an example, the first bitmap includes 4 bits, and the 4 bits are respectively associated with MBS session identifier 1 (that is, the MBS session identifier of MBS service 1) and MBS session identifier 2 (that is, the MBS session identifier of MBS service 2) from low to high. ID), MBS session ID 3 (that is, the MBS session ID of MBS service 3), and MBS session ID 4 (that is, the MBS session ID of MBS service 4). The value of the first bitmap is: 1001. The MBS service that the terminal device joins is MBS service 1. MBS service 1 corresponds to the lowest bit in the first bitmap. According to the value of the lowest bit is 1, it can be determined MBS service 1 is activated and/or a paging message is triggered, and the terminal device determines to receive the paging message.

Application Example 3

In this example, the network device indicates to the terminal device the MBS service group that triggers the paging message through the paging DCI.

Specifically, the paging DCI carries third information, and the third information is an MBS service group list or a second bitmap.

Wherein, the MBS service group list is used to indicate one or more MBS service groups, and the MBS services belonging to the MBS service groups in the MBS service group list are considered to be activated or trigger the MBS service of the paging message, and do not belong to the MBS service group The MBS services of the MBS service groups in the list are regarded as the MBS services that are not activated or do not trigger a paging message.

As an example, the MBS service group list includes one or more MBS session identifiers (or one or more MBS service indexes), and each one or more MBS session identifiers in the one or more MBS session identifiers corresponds to one MBS service, so , the MBS service group list may indicate one or more MBS service groups.

Wherein, each bit in the second bitmap corresponds to an MBS group identifier of an MBS service group; the value of the bit is used to indicate whether the MBS service group corresponding to the bit is activated and/or whether the MBS service group is triggered paging message.

In the above solution, if the first MBS service that the terminal device joins belongs to the MBS service in an MBS service group in the MBS service group list, then the terminal device determines to receive the paging message; if the terminal device joins If the first MBS service does not belong to any MBS service in any MBS service group in the MBS service group list, then the terminal device determines not to receive the paging message.

In the above solution, if the terminal device determines based on the second bitmap that the MBS service group to which the first MBS service the terminal device belongs to is activated and/or triggers a paging message, then the terminal device determines to receive Paging message; if the terminal device determines based on the second bitmap that the MBS service group to which the first MBS service that the terminal device belongs to is not activated and/or does not trigger a paging message, then the terminal device determines Do not receive paging messages.

In this example, the network device can configure the MBS service group to which the MBS service it joins belongs to for the terminal device through NAS signaling or RRC dedicated signaling.

Application Example 4

In this example, the network device indicates the paging type of the paging message to the terminal device through the paging WUS. The terminal device determines whether to monitor the paging DCI through the paging WUS. Here, not monitoring the paging DCI means not receiving a paging message, and monitoring the DCI means that a paging message may be received.

Here, a paging WUS is associated with one or more POs, and the time domain position of the paging WUS is located before the POs associated with it. As an example, as shown in FIG. 7 , a paging WUS has an association relationship with an immediately following PO.

Specifically, the paging WUS carries first information, and the first information is used to indicate that the paging type of the paging message is one of the following: MBS paging only, Unicast paging only, MBS paging and unicast paging.

In this example, for a terminal device that is not configured with the MBS service or does not support the MBS service, if the first information in the paging WUS indicates that the paging type of the paging message is MBS only paging, then the terminal device is not in the paging WUS associated The PO monitors the paging DCI.

Application example five

Specifically, the paging WUS carries second information, and the second information is a first bitmap (bitmap), and each bit in the first bitmap corresponds to an MBS session identifier or an MBS index of an MBS service; The value of the bit is used to indicate whether the MBS service corresponding to the bit is activated and/or whether a paging message is triggered. As an example, the value of a bit is 1 (or 0) to indicate that the MBS service corresponding to the bit is activated and/or a paging message is triggered, and the value of a bit is 0 (or 1) is used to indicate that the The MBS service corresponding to the bit is not activated and/or the paging message is not triggered.

In the above solution, if the terminal device determines based on the first bitmap that the first MBS service that the terminal device joins is activated and/or a paging message is triggered, then the terminal device determines that when paging the WUS associated Monitor the paging DCI on the PO; if the terminal device determines based on the first bitmap that the first MBS service that the terminal device joins is not activated and/or does not trigger a paging message, then the terminal device determines that it is not in the paging Monitor the paging DCI on the PO associated with the WUS.

Further, if the terminal device determines to monitor the paging DCI and receive the paging message, the terminal device initiates an RRC connection establishment process or an RRC connection recovery process, and after the RRC connection is established or the RRC connection is restored, receiving the paging message triggers Business.

Application example six

In this example, the network device indicates to the terminal device the MBS service group that triggers the paging message through the paging WUS.

Specifically, the paging WUS carries third information, and the third information is an MBS service group list or a second bitmap.

In the above solution, if the first MBS service joined by the terminal device belongs to the MBS service in an MBS service group in the MBS service group list, the terminal device determines to monitor the paging on the PO associated with the paging WUS DCI: if the first MBS service joined by the terminal device does not belong to the MBS service in any MBS service group in the MBS service group list, the terminal device determines not to monitor paging on the PO associated with the paging WUS DCI.

In the above solution, if the terminal device determines based on the second bitmap that the MBS service group to which the first MBS service the terminal device belongs to is activated and/or a paging message is triggered, then the terminal device determines that the Monitor the paging DCI on the PO associated with the paging WUS; if the terminal device determines based on the second bitmap that the MBS service group to which the first MBS service the terminal device belongs to is not activated and/or paging is not triggered message, the terminal device determines not to monitor the paging DCI on the PO associated with the paging WUS.

Further, if the terminal device determines to receive and monitor the paging DCI and receive the paging message, the terminal device initiates an RRC connection establishment process or an RRC connection recovery process, and receives the paging message after the RRC connection is established or the RRC connection is restored. triggered business.
