In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, eMBB), low latency high reliability communication (URLLC), large scale machine-like communication (massive machinery)e-Type Communications，mMTC)。

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a working mode of tight coupling (tight interworking) between LTE and NR is proposed.

RRC state

5G for the purposes of reducing air interface signaling and fast recovery of radio connections, fast recovery of data traffic, a new radio resource control (Radio Resource Control, RRC) state, namely an RRC INACTIVE (RRC_INACTIVE) state, is defined. This state is different from the RRC IDLE (rrc_idle) state and the RRC ACTIVE (rrc_active) state. Wherein,

1) Rrc_idle state (simply referred to as IDLE state): mobility is cell selection reselection based on terminal equipment, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side has no terminal equipment context and 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 that the location of the terminal device is cell specific. Mobility is network-side controlled mobility. Unicast data may be transmitted between the terminal device and the base station.

3) Rrc_inactive state (simply referred to as INACTIVE state): mobility is cell selection reselection based on terminal equipment, connection between CN-NR exists, terminal equipment context exists on a certain base station, paging is triggered by RAN, paging area based on RAN is managed by RAN, network side knows that the position of terminal equipment is based on paging area level of RAN.

MBMS

MBMS is a technology for transmitting data from one data source to a plurality of terminal equipments through a shared network resource, which can effectively utilize the network resource while providing a multimedia service, and realize broadcasting and multicasting of a multimedia service of a higher rate (e.g., 256 kbps).

Due to the low MBMS spectrum efficiency, it is not sufficient to effectively carry and support the operation of the mobile tv type service. In LTE, 3GPP has therefore explicitly proposed to enhance the support capability for the downlink high speed MBMS service and to determine the design requirements for the physical layer and the air interface.

The 3gpp R9 introduces evolved MBMS (eMBMS) into LTE. eMBMS proposes the concept of a single frequency network (Single Frequency Network, SFN), i.e. a multimedia broadcast multicast service single frequency network (Multimedia Broadcast multicast service Single Frequency Network, MBSFN), wherein the MBSFN uses a unified frequency to simultaneously transmit traffic data in all cells, but synchronization between the cells is guaranteed. The method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the frequency spectrum efficiency can be correspondingly and greatly improved. eMBMS implements broadcast and multicast of services based on IP multicast protocols.

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

A single cell point-to-multipoint (Single Cell Point To Multiploint, SC-PTM) concept is introduced in 3gpp r13, SC-PTM being based on the MBMS network architecture.

MBMS introduces new logical channels including Single Cell multicast control channel (SC-MCCH) and Single Cell multicast transport channel (SC-MTCH) and Single Cell-Multicast Transport Channel. The SC-MCCH and SC-MTCH are mapped onto a Downlink-Shared Channel (DL-SCH), and further, the DL-SCH is mapped onto a physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), wherein the SC-MCCH and SC-MTCH belong to a logical Channel, the DL-SCH belongs to a transport Channel, and the PDSCH belongs to a physical Channel. The SC-MCCH and SC-MTCH do not support hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) operation.

MBMS introduces a new system information block (System Information Block, SIB) type, SIB20. Specifically, the configuration information of the SC-MCCH is transmitted through the SIB20, and one cell has only one SC-MCCH. The configuration information of the SC-MCCH comprises: the modification period of the SC-MCCH, the repetition period of the SC-MCCH, the radio frame and subframe for scheduling the SC-MCCH and other information. Further, 1) the boundary of the modification period of the SC-MCCH satisfies SFN mod m=0, where SFN represents a system frame number of the boundary, and m is a modification period (i.e., SC-MCCH-modification period) of the SC-MCCH configured in SIB20. 2) The radio frame of the scheduling SC-MCCH meets the following conditions: SFN mod MCCH-repetition period = MCCH-Offset, where SFN represents the system frame number of the radio frame, MCCH-repetition period represents the repetition period of the SC-MCCH, and MCCH-Offset represents the Offset of the SC-MCCH. 3) The subframes of the scheduling SC-MCCH are indicated by SC-MCCH-Subframe.

The SC-MCCH is scheduled through a physical downlink control channel (Physical Downlink Control Channel, PDCCH). In one aspect, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), i.e., single Cell RNTI (SC-RNTI), is introduced to identify a PDCCH (e.g., SC-MCCH PDCCH) for scheduling the SC-MCCH, optionally with the SC-RNTI fixed value FFFC. On the other hand, a new RNTI, i.e., a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) is introduced to identify a PDCCH (e.g., notification PDCCH) for indicating a change notification of the SC-MCCH, optionally, the SC-N-RNTI is fixed to a value of FFFB; further, the change notification may be indicated with one bit of 8 bits (bits) of DCI 1C. In LTE, the configuration information of SC-PTM is based on the SC-MCCH configured by SIB20, and then SC-MCCH configures SC-MTCH for transmitting service data.

Specifically, the SC-MCCH transmits only one message (i.e., scptm configuration) for configuring configuration information of the SC-PTM. The configuration information of the SC-PTM comprises: temporary mobile Group identity (Temporary Mobile Group Identity, TMGI), session identity (session id), group RNTI (G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information, SC-PTM service information of neighbor cells, and the like. Note that SC-PTM in R13 does not support the robust header compression (Robust Header Compression, ROHC) function.

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

When [ (SFN 10) +subframe number ] module (SC-MTCH-scheduling cycle) =sc-MTCH-scheduling offset is satisfied, a timer ondurationtimerscpm is started;

when receiving downlink PDCCH scheduling, starting a timer drx-InactivityTimerSCPTM;

the downstream SC-PTM service is received only when the timer onduration timerscpm or drx-incaactyitimerscpm is running.

The SC-PTM service continuity adopts the MBMS service continuity concept based on SIB15, namely a mode of SIB15 and MBMSInterestindication. The traffic continuity of the terminal device 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 (referred to as a first SIB) is defined, where the first SIB includes configuration information of a first MCCH, where the first MCCH is a control channel of an MBMS service, in other words, the first SIB is used to configure configuration information of a control channel of an NR MBMS, and optionally, the control channel of the NR MBMS may also be referred to as an NR MCCH (i.e. the first MCCH).

Further, the first MCCH is used to carry the first signaling, where the name of the first signaling is not limited, for example, the first signaling is signaling a, and the first signaling includes configuration information of at least one first MTCH, where the first MTCH is a traffic channel (also referred to as a data channel or a transmission channel) of an MBMS service, and the first MTCH is used to transmit MBMS service data (such as service data of NR MBMS). In other words, the first MCCH is used to configure configuration information of a traffic channel of the NR MBMS, alternatively, the traffic channel of the NR MBMS may also be called as NR MTCH (i.e., the first MTCH).

Specifically, the first signaling is used for configuring a service channel of the NR MBMS, service information corresponding to the service channel, and scheduling information corresponding to the service channel. Further optionally, the service information corresponding to the service channel, for example, TMGI, session id, and other identification information for identifying the service. Scheduling information corresponding to the service channel, for example, RNTI used when MBMS service data corresponding to the service channel is scheduled, for example, G-RNTI, DRX configuration information, and the like.

The transmissions of the first MCCH and the first MTCH are scheduled based on the PDCCH. The RNTI used for scheduling the PDCCH of the first MCCH uses a unique network identifier, i.e. a fixed value. The RNTI used for scheduling PDCCH use of the first MTCH is configured through the first MCCH.

It should be noted that, in the embodiment of the present application, the naming of the first SIB, the first MCCH and the first MTCH is not limited. For convenience of description, the first SIB may also be simply referred to as SIB, the first MCCH may also be simply referred to as MCCH, and the first MTCH may also be simply referred to as MTCH, and a PDCCH (i.e. MCCH PDCCH) for scheduling the MCCH and a notification PDCCH are configured through SIB, where a PDSCH (i.e. MCCH PDSCH) for transmitting the MCCH is scheduled through DCI carried in MCCH PDCCH. Further, M PDCCHs for scheduling MTCH (i.e., MTCH 1 PDCCH, MTCH 2 PDCCH, …, MTCH M PDCCH) are configured through the MCCH, wherein DCI carried by MTCH n PDCCH schedules PDSCH for transmitting MTCH n (i.e., MTCH n PDSCH), n being an integer greater than or equal to 1 and less than or equal to M. The MCCH and the MTCH are mapped to the DL-SCH, and further, the DL-SCH is mapped to the PDSCH, wherein the MCCH and the MTCH belong to a logical channel, the DL-SCH belongs to a transport channel, and the PDSCH belongs to a physical channel.

It should be noted that, although the above scheme is described by taking MBMS as an example, the description of "MBMS" may be replaced by "MBS". The embodiments of the present application are described using MBS as an example, and the description of "MBS" may be replaced by "MBMS".

Energy saving

In order to achieve energy saving of the terminal device, an energy saving Wake Up Signal (WUS) is introduced by NR energy saving enhancement, which may also be referred to as energy saving Signal or Wake Up Signal for short. In standardization, an energy-saving wake-up signal is used in combination with a Discontinuous Reception (DRX) mechanism, and the specific technical principle is that a terminal device receives the energy-saving wake-up signal before a DRX ON duration, as shown in fig. 2, when the terminal device has data transmission in one DRX cycle, the energy-saving wake-up signal instructs the terminal device to monitor a PDCCH, i.e. 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 one DRX period, the energy-saving wake-up signal indicates that the terminal device does not monitor the PDCCH, i.e. 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 equipment does not have data transmission, the terminal equipment can omit PDCCH monitoring during the DRX ON duration, thereby realizing energy saving. The time before the terminal device is DRX ON Duration is referred to as DRX inactive time, and the time at the terminal device is referred to as DRX active time.

In NR, paging is also periodically sent to terminal devices, where the terminal devices monitor Paging DCI for Paging Occasions (POs), and for one terminal device, its associated PO location is related to its UE ID, and the POs of different terminal devices are scattered within the Paging cycle, as shown in fig. 3.

In NR systems, many scenarios require support of multicast type and broadcast type traffic demands, such as in the internet of vehicles, industrial internet, etc. It is necessary to introduce multicast type and broadcast type MBS services in the NR. It should be noted that, the multicast type MBS service refers to an MBS service transmitted through a multicast manner. The broadcast type MBS service refers to an MBS service transmitted through a broadcast manner.

In the NR system, for the multicast type MBS service, the MBS service is addressed to all terminal equipments in a certain group. The terminal equipment receives the multicast MBS service in the RRC connection state, and the terminal equipment can receive the multicast MBS service data in the PTM mode or the PTP mode. Referring to fig. 4, the MBS service data of the ptm mode scrambles the corresponding scheduling information through the G-RNTI configured by the network side, and the MBS service data of the PTP mode scrambles the corresponding scheduling information through the C-RNTI.

For multicast type MBS service, after receiving the MBS service issued by the core network from the shared tunnel (tunnel), the base station may issue the MBS service to all terminal devices in a group through an air interface. Here, the base station may issue the MBS service to all terminal equipments in a group by PTP and/or PTM. For example: a group comprises a terminal device 1, a terminal device 2 and a terminal device 3, wherein the base station can issue MBS service to the terminal device 1 in a PTP mode, issue MBS service to the terminal device 2 in a PTP mode, and issue MBS service to the terminal device 3 in a PTP mode; or the base station can issue MBS business to the terminal equipment 1 in a PTP mode, and issue MBS business to the terminal equipment 2 and the terminal equipment 3 in a PTM mode; or, the base station may send the MBS service to the terminal device 1, the terminal device 2 and the terminal device 3 in the PTM mode. Referring to fig. 5, a shared GTP tunnel (Shared GTP tunnel) is used between the core network and the base station to transmit MBS service, i.e., both PTM-type MBS service and PTP-type MBS service are shared with the GTP tunnel. The base station transmits MBS service data to the UE1 and the UE2 according to the PTM mode, and transmits MBS service data to the UE3 according to the PTP mode.

For the MBS service in the multicast mode, if no service data is available, the terminal equipment can be temporarily left from the RRC connection state to return to the RRC idle state or the RRC inactive state, thereby realizing the energy saving of the terminal equipment. When the service data exists, the terminal equipment is awakened to enter an RRC connection state by a mode of sending a group notice to receive the MBS service of the multicast mode. Here, the group notification adopts paging message, DCI of which (i.e. paging DCI) is scrambled by P-RNTI, and the network side sends paging DCI for activating MBS service and paging message on each PO of the cell, and the paging message identifies the activated target MBS service by carrying MBS session identifier. In NR, paging of multiple users corresponding to the same PO may be multiplexed in one paging message, so multiple users corresponding to one PO may monitor paging messages of MBS service, and even if some users do not participate in the MBS service, paging messages of MBS service may wake up the users, which may affect the users, for example, cause electricity consumption of the users. In addition, NR supports beam scanning (beam scanning) transmission, so that one paging message may be transmitted in one cell, and the specific number of parts depends on the number of Synchronization Signal Blocks (SSBs) actually transmitted by the cell, so that the paging message of the MBS service may have a high load, and wireless resources are wasted. For this reason, the following technical solutions of the embodiments of the present application are provided.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 6 is a flow chart of a paging method according to an embodiment of the present application, as shown in fig. 6, where the paging method includes the following steps:

step 601: the network equipment sends a first signaling to the terminal equipment, and the terminal equipment receives the first signaling, wherein the first signaling is associated with a first paging message; the first signaling carries first indication information, the first indication information is used for the terminal equipment to determine whether to monitor first DCI and/or receive the first paging message, and the first DCI is paging DCI used for scheduling the first paging message.

In some alternative embodiments, the network device is a base station.

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

The paging DCI is used for scheduling paging messages, and is scrambled by the P-RNTI.

It should be noted that, the paging WUS has an association relationship with one or more paging occasions, and the paging WUS is located before the paging occasion associated with the paging WUS, where the paging WUS is used to indicate whether to monitor the paging DCI in the PO associated with the paging WUS. As an example, the paging WUS has an association relationship with one paging occasion immediately after the paging WUS, and each PO is preceded by one paging WUS, where the paging WUS is used to indicate whether to monitor paging DCI or receive paging messages in the paging occasion immediately after the paging WUS, so as to achieve the purpose of saving power of the terminal device.

The techniques of the embodiments of the present application are described below in connection with different implementations of the first signaling.

In some optional embodiments, the first indication information includes first information, where the first information is used to indicate a paging type of the first paging message.

Option 1: the first information is used for indicating that the paging type of the first paging message is MBS paging.

As an example, the first information is used to indicate MBS paging only, and the paging type representing the first paging message is MBS paging.

In the case that the paging type of the first paging message is MBS paging, the first paging message carries an MBS session identifier, where the MBS session identifier is used to determine an MBS service to be paged.

Option 2: the first information is used to indicate that the paging type of the first paging message is unicast paging.

In the above scheme, for a terminal device that is not configured with MBS service or does not support MBS service, if the first information is used to indicate that the paging type of the first paging message is MBS paging, the terminal device determines not to receive the first paging message.

Scheme 1-2

In some optional embodiments, the first indication information includes second information, where the second information is used to indicate MBS service that triggers the first paging message.

In some optional embodiments, the second information is a first bit map, where each bit in the first bit map corresponds to an MBS session identifier or an MBS index of one MBS service; the value of the bit is used for indicating whether the MBS service corresponding to the bit is activated and/or whether the first paging message is triggered.

In some optional embodiments, N bits in the first bit map correspond to MBS session identifiers or MBS indexes of N MBS services, where N is a positive integer; the N MBS services are MBS services that are ongoing or upcoming or supported by the cell.

In some alternative embodiments, MBS session identities or MBS indexes of the N MBS services are configured through radio resource control RRC signaling or system broadcast messages.

In some optional embodiments, the correspondence between the N bits in the first bit map and MBS session identifiers or MBS indexes of the N MBS services is protocol-agreed or configured by a network device.

In some optional embodiments, the N bits in the first bit map correspond to MBS session identifiers or MBS indexes of the N MBS services in order from low to high; or, the N bits in the first bit map correspond to MBS session identifiers or MBS indexes of the N MBS services in order from low to high.

In some optional embodiments, the network device sends first configuration information to the terminal device, where the terminal device receives the first configuration information, and the first configuration information is used to determine an MBS service group to which the first MBS service joined by the terminal device belongs. Optionally, the first configuration information is carried in non-access stratum (NAS) signaling or RRC signaling.

Option 1: the third information is an MBS service group list.

In the above scheme, if the first MBS service added by the terminal device belongs to an MBS service in one MBS service group in the MBS service group list, the terminal device determines to receive the first paging message; if the first MBS service added by the terminal equipment does not belong to the MBS service in any MBS service group in the MBS service group list, the terminal equipment determines not to receive the first paging message.

Option 2: the third information is a second bit map, and each bit in the second bit map corresponds to an MBS group identifier of one MBS service group; the value of the bit is used for indicating whether the MBS service group corresponding to the bit is activated and/or whether the first paging message is triggered.

In some optional embodiments, M bits in the second bitmap correspond to MBS group identifiers of the M MBS service groups in order from low to high; or, the M bits in the second bitmap correspond to the MBS group identities of the M MBS service groups in the order from the low bit to the high bit.

In the above scheme, if the terminal device determines, based on the second bitmap, that an MBS service group to which a first MBS service added by the terminal device belongs is activated and/or the first paging message is triggered, the terminal device determines to receive the first paging message; and if the terminal equipment determines that the MBS service group to which the first MBS service added by the terminal equipment belongs is not activated and/or the first paging message is not triggered based on the second bit map, the terminal equipment determines not to receive the first paging message.

Scheme II

The first signaling is a first WUS, the first WUS is located before a first paging occasion, and the first paging occasion is used for transmitting the first DCI; the first indication information carried in the first WUS is used for the terminal device to determine whether to monitor the first DCI at the first paging occasion.

Scheme 2-1

In the above scheme, for a terminal device that is not configured with MBS service or does not support MBS service, if the first information is used to indicate that the paging type of the first paging message is MBS paging, the terminal device determines that the first DCI is not monitored at a first paging occasion, and a time domain position of the first paging occasion is located after the first WUS.

The following describes the technical scheme of the embodiment of the present application with reference to specific application examples.

Application example 1

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

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

If the first information indicates that the paging type of the paging message is MBS paging only, the paging message only carries an MBS session identifier. If the first information indicates that the paging type of the paging message is Unicast paging only, the paging message only carries the terminal equipment (i.e. UE ID), and the UE ID may be, for example, 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, the paging message carries an MBS session identifier and a terminal equipment (i.e. UE ID).

In this example, for a terminal device that does not configure or support an 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 may be indicated by the value of the first information, for example, the first information is 2-bit information, the value of the 2-bit information may be 00, 01, 10, 11, and the paging type of the paging message is indicated by some or all of the values.

Application instance two

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

Specifically, the paging DCI carries second information, where 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 one MBS service; the value of the bit is used for indicating whether the MBS service corresponding to the bit is activated and/or whether the paging message is triggered. As an example, a bit value of 1 (or 0) is used to indicate that the MBS service corresponding to the bit is activated and/or triggered by the paging message, and a bit value of 0 (or 1) is used to indicate that the MBS service corresponding to the bit is not activated and/or not triggered by the paging message.

In the above scheme, if the terminal device determines that the first MBS service added by the terminal device is activated and/or triggers a paging message based on the first bitmap, the terminal device determines to receive the paging message; and if the terminal equipment determines that the first MBS service added by the terminal equipment is not activated and/or the paging message is not triggered based on the first bit map, the terminal equipment determines not to receive the paging message.

Further, if the terminal device determines to receive the paging message, the terminal device initiates an RRC connection establishment procedure or an RRC connection recovery procedure, and receives a service triggered by the paging message after establishing an RRC connection or recovering the RRC connection.

As an example, the first bit map includes 4 bits, and 4 bits are respectively associated with MBS session identification 1 (i.e., MBS session identification of MBS service 1), MBS session identification 2 (i.e., MBS session identification of MBS service 2), MBS session identification 3 (i.e., MBS session identification of MBS service 3), and MBS session identification 4 (i.e., MBS session identification of MBS service 4) from a low order bit to a high order bit. The first bitmap has the following values: 1001, the MBS service added by the terminal device is MBS service 1, MBS service 1 corresponds to the lowest bit in the first bitmap, according to the value of the lowest bit being 1, it may be determined that MBS service 1 is activated and/or triggered to receive the paging message, and the terminal device determines to receive the paging message.

Application example three

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

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

Wherein the MBS service group list is used for indicating one or more MBS service groups, MBS services belonging to the MBS service groups in the MBS service group list are regarded as MBS services activated or triggered by paging messages, and MBS services not belonging to the MBS service groups in the MBS service group list are regarded as MBS services not activated or triggered by paging messages.

As an example, the MBS service group list includes one or more MBS session identifications (or one or more MBS service indexes), each of the one or more MBS session identifications corresponding to one MBS service, such that the MBS service group list may indicate one or more MBS service groups.

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

In the above scheme, if the first MBS service added by the terminal device belongs to an MBS service in one MBS service group in the MBS service group list, the terminal device determines to receive a paging message; if the first MBS service added by the terminal equipment does not belong to the MBS service in any MBS service group in the MBS service group list, the terminal equipment determines not to receive the paging message.

In the above scheme, if the terminal device determines, based on the second bitmap, that the MBS service group to which the first MBS service added by the terminal device belongs is activated and/or triggers a paging message, the terminal device determines to receive the paging message; and if the terminal equipment determines that the MBS service group to which the first MBS service added by the terminal equipment belongs is not activated and/or the paging message is not triggered based on the second bit map, the terminal equipment determines not to receive the paging message.

In this example, the network device may configure, for the terminal device, an MBS service group to which the added MBS service belongs through NAS signaling or RRC dedicated signaling.

Application example four

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

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

Specifically, the paging WUS carries first information, where 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 does not configure or support an MBS service, if the first information in the paging WUS indicates that the paging type of the paging message is MBS only paging, the terminal device does not monitor paging DCI on a PO associated with the paging WUS.

Application example five

In this example, the network device indicates to the terminal device, through the paging WUS, MBS services triggering the paging message.

Specifically, the paging WUS carries second information, where 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 one MBS service; the value of the bit is used for indicating whether the MBS service corresponding to the bit is activated and/or whether the paging message is triggered. As an example, a bit value of 1 (or 0) is used to indicate that the MBS service corresponding to the bit is activated and/or triggered by the paging message, and a bit value of 0 (or 1) is used to indicate that the MBS service corresponding to the bit is not activated and/or not triggered by the paging message.

In the above scheme, if the terminal device determines that the first MBS service added by the terminal device is activated and/or triggers a paging message based on the first bitmap, the terminal device determines to monitor paging DCI on a PO associated with paging WUS; and if the terminal equipment determines that the first MBS service added by the terminal equipment is not activated and/or the paging message is not triggered based on the first bit map, the terminal equipment determines not to monitor paging DCI on the PO associated with the paging WUS.

Further, if the terminal device determines to monitor paging DCI and receive paging message, the terminal device initiates an RRC connection establishment procedure or an RRC connection restoration procedure, and receives a service triggered by the paging message after establishing RRC connection or restoring RRC connection.

Application example six

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

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

In the above scheme, if the first MBS service added by the terminal device belongs to an MBS service in one MBS service group in the MBS service group list, the terminal device determines to monitor paging DCI on a PO associated with paging WUS; if the first MBS service added by the terminal equipment does not belong to the MBS service in any MBS service group in the MBS service group list, the terminal equipment determines not to monitor paging DCI on the PO associated with paging WUS.

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

Further, if the terminal device determines to receive the listening paging DCI and receive the paging message, the terminal device initiates an RRC connection establishment procedure or an RRC connection recovery procedure, and receives a service triggered by the paging message after establishing an RRC connection or recovering the RRC connection.

According to the technical scheme of the embodiment of the application, the network equipment informs the terminal equipment whether to monitor the paging DCI or whether to receive the paging message through the paging DCI or the paging WUS, so that the purpose of saving electricity of the terminal equipment is achieved, and meanwhile, the influence of paging on the terminal equipment which does not support MBS service or does not configure MBS service is reduced.
