Description

Field of technology to which the present invention relates

[0001] The present invention relates to the field of communication technologies, in particular to a method and device for controlling switching of a tracking state and a data carrier.

Prior art of the present invention

[0002] In the 5G NR (New Radio Access Technology) system, MBMS (Multimedia Broadcast Multicast Services) or MBS (Multicast Broadcast Services) services can be scheduled and transmitted in two different ways described below.

[0003] The first method is dynamic planning.

[0004] The PDCCH (Physical Downlink Control Channel) schedules the PDSCH (Physical Downlink Shared Channel) for transmission. The PDCCH scheduling the MBS is indicated by a scheduling identifier specific to a particular MBS service. The scheduling identifier specific to a particular MBS service includes, among other things, the G-RNTI (Group Radio Network Temporary Identifier, a temporary radio network identifier for MBS).

[0005] The second method is semi-permanent scheduling (SPS).

[0006] The base station configures periodic PDSCH resources, and through these PDSCH resources, the terminal obtains MBS data.

[0007] MBS services can be identified using the following MBS identifiers: TMGI (Temporary Mobile Group Identifier), MBS Session ID (Identifier), MBS Quality of Service Flow ID (QoS Flow ID), MBS RB ID (MBS Bearer ID), and MBS LCH ID (MBS Logical Channel ID).

[0008] The MBS transmission mode may include two types of modes described below.

[0009] First transmission mode, transmission mode 1 (multicast transmission)

[0010] The terminal enters the CONNECTED state of the RRC (Radio Resource Control) to obtain the reception configuration information corresponding to the MBS, and obtains the MBS based on the reception configuration information. The network side transmits the reception configuration information corresponding to the MBS to the terminal through terminal-specific signaling.

[OOP] Second transmission mode, transmission mode 2 (broadcast transmission)

[0012] The terminal may obtain reception configuration information corresponding to the MBS in any of the states such as the IDLE state, the INACTIVE state, or the CONNECTED state, and obtain the MBS based on the reception configuration information.

[0013] The network side transmits MBS reception configuration information to the terminal through system information such as SIB (System Information Block) and through MBS control channel information such as MCCH (MBS Control Channel).

[0014] Due to the different transmission cycles of different MBS, the network side may configure the terminal to receive different MBS in a discontinuous manner. In other words, different MBS services may correspond to different discontinuous reception configuration information, as shown in Fig. 1.

[0015] After the network side configures the reception configuration information corresponding to the MBS for the terminal, the terminal needs to monitor the MBS transmission (e.g., monitor the G-RNTI of the PDCCH) during the MBS scheduling duration configured by the network, such as the service monitoring duration corresponding to the MBS monitoring duration timer (mbsOnDurationTimer).

[0016] However, the network side may temporarily stop transmission while the terminal side will still monitor the MBS transmission according to the MBS scheduling duration set by the network side, resulting in an increase in the power consumption of the terminal.

[00117] It should be understood that although the terms "first", "second" and "third" may be used in embodiments of the present invention to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish different types of information of the same type from each other. For example, without departing from the scope of embodiments of the present invention, first information may also be referred to as second information, and - likewise - second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "upon", "when" and "upon determining that".

[00118] A method for controlling switching of a tracking state according to the present invention, implemented by a network device, is described below.

[00119] Embodiments of the present invention provide a method for controlling switching of a tracking state, which is shown in Fig. 2, which is a flow chart illustrating a method for controlling switching of a tracking state according to one embodiment of the present invention. This method can be implemented by a network device, and it can include performing the steps described below.

[00120] In step 201, reception configuration information corresponding to a multicast broadcast service (MBS) is configured for the terminal, wherein the reception configuration information is used by the terminal to obtain MBS in a discontinuous reception mode.

[00121] At step 202, target control information is transmitted to the terminal, wherein the target control information is used to activate or deactivate MBS reception tracking for the terminal.

[00122] In the above embodiments of the present invention, the tracking switching module is configured to start or stop tracking the reception of the MBS based on an indication in the target control information or in the reception configuration information corresponding to the MBS configured by the network device for the terminal.

[00123] In some optional embodiments of the present invention, the reception configuration information corresponding to the MBS configured by the network device for the terminal may include, but is not limited to, at least one of the following elements: an MBS service monitoring cycle; a first timer used to indicate a service monitoring duration in each service monitoring cycle; a service monitoring start position in each service monitoring cycle; a second timer used to indicate that the network device has new data to be scheduled; a third timer used to instruct the terminal to perform HARQ (Hybrid Automatic Repeat Request) feedback; or a fourth timer used to instruct the terminal to receive data retransmitted by the network device.

[00124] The MBS service tracking cycle (designated, for example, as mbsCycle) is used to instruct the terminal to periodically track the MBS based on the service tracking cycle. The first timer (designated, for example, as mbsOnDurationTimer) may be used to indicate the service tracking duration during which the terminal is expected to track the service within each service tracking cycle. The service tracking start position (designated, for example, as mbsStartOffset) may be used to indicate the starting point of the time domain at which the terminal begins tracking the MBS within each service tracking cycle.

[00125] The second timer may be an inactive timer (designated, for example, as mbsmactivityTimer). If the network device contains any new data to be scheduled, the terminal may be instructed to start or restart the second timer. The third timer may be a HARQ feedback timer (designated, for example, as mbsHARQ-RTT-Timer). The terminal may start the third timer upon receipt of downlink data and when there is HARQ information to be reversed in response to receipt of the downlink data. The fourth timer may be a HARQ retransmission timer (designated, for example, as mbsHARQ-RxTimer). The terminal starts the fourth timer after the third timer expires. When the fourth timer is activated, the network device may send the retransmitted data to the terminal.

[00126] The above description is for illustrative purposes only. In actual implementation, network devices may configure corresponding reception configuration information for terminals in accordance with the MBS requirements. Other types of reception configuration information shall be within the scope of legal protection of the present invention.

[00127] In one possible implementation example, it is provided that when the target control information is used to activate MBS reception tracking, the target control information includes one of the following elements: a trigger signal (WUS), a target downlink control information (DCI), or a target medium access control element (MAC CE);

[00128] In another possible embodiment, it is provided that when the target control information is used to deactivate MBS reception tracking for a terminal, the target control information includes one of the following elements:

[00129] sleep mode transition signal, DCI target information, or MAC CE target element.

[00130] In an optional embodiment, the target DCI information is DCI information identified by a power save radio network temporary indicator (PS-RNTI). The target DCI information may be DCI information with a cyclic redundancy check (CRC) scrambled using the PS-RNTI.

[00131] In an optional embodiment, the target MAC CE element may be a MAC CE element specifically defined to activate or deactivate MBS reception tracking for the terminal.

[00132] In an optional embodiment, the content of the target control information used to activate or deactivate MBS reception tracking for the terminal may include, but is not limited to, at least one of the following elements:

[00133] MBS indicator information or MBS activation state information.

[00134] The MBS indicator information includes, but is not limited to, at least one of the following elements: an MBS identifier (such as the MBS identifier described in the "Background of the Present Invention" section); or an MBS scheduling identifier.

[00135] In this case, the MBS scheduling identifier may be, among others, at least one of the following identifiers: a dynamic scheduling identifier, such as a group radio network temporary identifier (G-RNTI); or a semi-persistent scheduling identifier, such as SPS (semi-persistent scheduling)-INT1.

[00136] The MBS activation state information may include, but is not limited to, at least one of the following: an activated state (or an "MBS reception tracking start" state); or a deactivated state (or an "MBS reception tracking stop" state).

[00137] The above description is for illustrative purposes only. Other types of target control information used to activate or deactivate MBS reception tracking for a terminal shall be within the scope of legal protection of the present invention.

[00138] In the above embodiments of the present invention, the network device can activate or deactivate the MBS reception monitoring on the terminal side by means of the above target control information of any type, which can be implemented in a simple manner and also ensures high operational availability.

[00139] Some optional embodiments of the present invention are described in connection with Fig. 3, which shows a flow chart illustrating a method for controlling a switch in a monitoring state according to one embodiment of the present invention. This method may be implemented by a network device and may include performing the steps described below.

[00140] In step 301, reception configuration information corresponding to the MBS is configured for the terminal by means of a radio resource control (RRC) message. The reception configuration information is used by the terminal to obtain the MBS in the discontinuous reception mode.

[00141] At step 302, target control information is transmitted to the terminal, wherein the target control information is used to activate or deactivate MBS reception tracking for the terminal.

[00142] In the above embodiments of the present invention, the network device may configure reception configuration information corresponding to the MBS for the terminal through an RRC message so that the terminal can receive the MBS in a discontinuous reception mode. In addition, the network device may activate MBS reception tracking for the terminal through target control information when there is an MBS; or deactivate MBS reception tracking for the terminal through target control information when the MBS transmission is stopped, which reduces power consumption of the terminal.

[00143] In some optional embodiments of the present invention, the RRC message transmitted by the network device to the terminal may include not only the reception configuration information corresponding to the MBS service configured by the network device for the terminal, but also an initial tracking state corresponding to the MBS service configured by the network device for the terminal. The initial tracking state provides for stopping the MBS reception tracking or starting the MBS reception tracking.

[00144] If, after the terminal receives the reception configuration information, the initial tracking state configured in the RRC message stops MBS reception tracking, the terminal may not start MBS reception tracking until the network device activates MBS reception tracking through target control information. The terminal performs MBS reception tracking based on the reception configuration information.

[00145] If, after the terminal receives the reception configuration information, the initial tracking state configured in the RRC message starts MBS reception tracking, the terminal may immediately start MBS reception tracking. Then, based on the target control information transmitted by the network device and used to deactivate MBS reception tracking, MBS reception tracking may be terminated.

[00146] In the above embodiments of the present invention, the network device may configure an initial MBS tracking state for the terminal, which can be implemented in a simple form and also further makes it possible to reduce the power consumption of the terminal.

[00147] In some optional embodiments of the present invention, the number of MBS services may be one or more. When the number of MBS services is more than one, the network device may configure different reception configuration information for different MSB services.

[00148] For example, for MBS #1, the network device may configure for the terminal the reception configuration information #1, such as mbsDRX-config-1. For MBS #2, the network device may configure for the terminal the reception configuration information #2, such as mbsDRX-config-2, wherein mbsDRX-config-1 and mbsDRX-config-2 may be different from each other.

[00149] In the above-described embodiments of the present invention, it is provided that when the network device configures reception configuration information corresponding to MBS for the terminal, different MBS services can be configured using different reception configuration information, which ensures high operational availability.

[00150] The technical solution regarding the control of the switching of the tracking state described below is implemented by the terminal side.

[00151] Embodiments of the present invention provide a method for controlling a switch of a tracking state, as shown in Fig. 4, which is a flow chart illustrating a method for controlling a switch of a tracking state according to one embodiment of the present invention. This method can be implemented by a terminal, and it includes performing the steps described below.

[00152] In step 401, MBS reception monitoring is started or stopped based on an indication in the received target control information and in the reception configuration information corresponding to the MBS service configured by the network device for the terminal.

[00153] The target control information is used to activate or deactivate MBS reception tracking for the terminal, and the reception configuration information is used by the terminal to receive MBS in the discontinuous reception mode.

[00154] In one possible implementation example, it is provided that, upon determining that the target control information is used to activate MBS reception tracking for the terminal, MBS reception tracking is started based on an indication in the target control information and in the reception configuration information.

[00155] In another possible implementation example, it is provided that, upon determining that the target control information is used to deactivate MBS reception tracking for the terminal, based on an indication in the target control information and in the reception configuration information, MBS reception tracking is terminated.

[00156] In the above-described embodiments of the present invention, the terminal can start or stop monitoring the MBS reception based on the indication in the target control information and the reception configuration information without having to constantly monitor the MBS reception in accordance with the configuration of the network device, which can reduce the power consumption of the terminal.

[00157] In some optional embodiments of the present invention, the terminal, depending on the initial tracking state, may be in the MBS reception tracking stop state, or the terminal may enter the MBS reception tracking stop state based on previously received target control information to deactivate MBS reception tracking for the terminal.

[00158] When the terminal determines that it is in the MBS reception tracking stop state, the terminal may track target control information used only for activating MBS reception tracking for the terminal.

[00159] In other words, when the terminal stops monitoring the MBS reception, there is no longer a need to monitor the target control information used to deactivate monitoring the MBS reception for the terminal.

[00160] In some optional embodiments of the present invention, the terminal, based on the initial tracking state, may be in the MBS reception tracking start state, or the terminal may enter the MBS reception tracking start state based on previously received target control information for activating MBS reception tracking for the terminal.

[00161] When the terminal determines that it is in the MBS reception tracking start state, the terminal may track target control information used only to deactivate MBS reception tracking for the terminal.

[00162] In other words, when the terminal starts MBS reception tracking, there is no need to track the target control information used to activate MBS reception tracking for the terminal.

[00163] In the above-described embodiments of the present invention, the terminal can monitor only the necessary target control information based on the current monitoring state, which is realized in a simple form with a high degree of operational availability, and also further makes it possible to reduce the power consumption of the terminal.

[00164] In some optional embodiments of the present invention, the terminal may determine the initial MBS tracking state using any of the methods described below.

[00165] In a first method, the initial tracking state may be determined based on an indication of the network device.

[00166] In one embodiment of the present invention, the network device may configure the reception configuration information corresponding to the MBS for the terminal through an RRC message, and the RRC message may also include an initial tracking state configured by the network device for the terminal. Based on the RRC message, the terminal determines the reception configuration information corresponding to the MBS and the initial tracking state.

[00167] In the second method, the initial tracking state is agreed upon in the protocol.

[00168] In one embodiment of the present invention, the initial monitoring states of different MBS services may be predetermined by negotiating them in a protocol. The terminal only needs to obtain the reception configuration information corresponding to the MBS, which is transmitted by the network device.

[00169] For example, the network device configures the mbsDRX-config-1 reception configuration information for the MBS #1 through an RRC message, and then the terminal immediately determines the initial tracking state corresponding to the MBS #1 based on the agreement in the protocol.

[00170] In one embodiment of the present invention, the initial tracking state includes stopping MBS reception tracking or starting MBS reception tracking.

[00171] In the above-described embodiments of the present invention, the terminal can determine the initial tracking state corresponding to the MBS based on the indication of the network device or directly by agreement in the protocol, which ensures ease of implementation and a high degree of operational availability.

[00172] Some optional embodiments of the present invention provide a method for controlling a switching of a tracking state, as shown in Fig. 5, which is a flow chart illustrating a method for controlling a switching of a tracking state according to one embodiment of the present invention. This method can be implemented by a terminal, and it includes performing the steps described below.

[00173] At step 501, the target control information is tracked at a point in the time domain used to track the target control information.

[00174] Target control information is used to activate or deactivate MBS reception tracking for a terminal.

[00175] At step 502, MBS reception monitoring is started or stopped based on an indication in the received target control information and in the reception configuration information corresponding to the MBS service configured by the network device for the terminal.

[00176] The reception configuration information is used by the terminal to receive MBS in the discontinuous reception mode.

[00177] In the above-described embodiments of the present invention, the terminal may monitor the target control information at a point in the time domain used to monitor the target control information in order to start or stop monitoring the MBS reception with a high degree of operational availability.

[00178] In one possible implementation example, it is provided that in the case when the target control information is monitored by the terminal at the target point of the time domain, and the bit value of the target control information is a first specified value, then the terminal determines that the target control information is being monitored, which is used to issue an indication of activation of MBS reception monitoring for the terminal. The first specified value may be equal to one.

[00179] For example, the terminal receives target control information at the target SFN (system frame number) point #1 of the time domain, slot #0, where a target cycle such as 10 milliseconds is used, and the target control information is one bit with a bit value of 1, after which the terminal determines that the target control information used to issue an indication of activation of MBS reception tracking for the terminal is being monitored.

[00180] In an alternative embodiment, it is provided that in the case where the target control information is monitored at the target point of the time domain, and the bit value of the target control information is a second predetermined value, the terminal determines that the target control information used to issue an indication of deactivation of MBS reception monitoring for the terminal is monitored. The second predetermined value may be equal to zero.

[00181] For example, the terminal receives target control information at the target SFN (system frame number) point #1 of the time domain, slot #0, where a target cycle such as 10 milliseconds is used, and the target control information is one bit with a bit value of 0, after which the terminal determines that the target control information used to issue an indication of deactivating MBS reception tracking for the terminal is being monitored.

[00182] In another possible implementation example, the target control information is not monitored by the terminal at the target point of the time domain, and it is determined that the terminal is in a state of stopping monitoring of MBS reception. In order to avoid losing MBS, the terminal may start monitoring of MBS reception based on the reception configuration information.

[00183] In an alternative embodiment, the target control information is not monitored by the terminal at the target point of the time domain, and it is determined that the terminal is in a state of starting to monitor the reception of MBS. In order to avoid unnecessary consumption of power by the terminal, the terminal may stop monitoring the reception of MBS based on the reception configuration information.

[00184] In the above-described embodiments of the present invention, it is provided that when the target pilot information is monitored by the terminal at a target point in the time domain, it can be determined, based on a bit value of the target pilot information, that the target pilot information is used to activate or deactivate monitoring of reception of MBS. When the target pilot information is not monitored by the terminal at a target point in the time domain, the terminal can switch the monitoring state based on the current monitoring state, in order to avoid loss of MBS or waste of power by the terminal, which ensures a high degree of operational availability.

[00185] In some optional embodiments of the present invention, the offset value of the target time domain point relative to the specified time domain point within each target cycle is a predetermined offset value. The duration of the target cycle may be a positive integer multiple of the MSB service tracking cycle, or a positive integer multiple of the paging cycle duration. The specified time domain point may be, among others, at least one of the following points: an MBS service tracking start point, a paging tracking start point, or a multicast control channel change start indication point.

[00186] The indication point for starting a change of the multicast control channel may be, among other things, a starting point for indicating the indication information used to issue an indication to start the MBS of the MCCH, or a starting point for indicating the indication information about changing the MCCH configuration message.

[00187] For example, the specified point of the time domain is the starting point of the MBS service #1 tracking. As shown in Fig. 6A, the duration of the tracking cycle of the MBS service #1 is 10 slots (time slots), and the predetermined offset value is -2 slots, and the duration of the target cycle is equal to the duration of the MBS service tracking cycle. If the duration of the MBS service tracking cycle is 10 milliseconds, and the time slot corresponding to the starting point of the service tracking is slot #2, the terminal can determine the position of slot #0 in each tracking cycle of the MBS service as the target point of the time domain, and track the target control information at the target point of the time domain.

[00188] For example, a predetermined point in the time domain is a paging tracking start point. As shown in Fig. 6B, the paging cycle duration is 100 milliseconds, and the paging start points are SFNs #1 and #2 in the time domain. The target cycle duration is equal to the paging cycle duration, which are both 100 milliseconds; and a predetermined offset value is -2 slots. The terminal determines the cycle duration to be 100 milliseconds, sets the position of SFN #1 and slot #0 as target points in the time domain, and tracks the target control information at the target point in the time domain.

[00189] When the specified point of the time domain is the indication point of the start of the change of the multicast control channel, the method for determining the target point of the time domain is similar to the methods described above, and is not described again hereinafter.

[00190] In the above-described embodiments of the present invention, the terminal can determine a target point in the time domain for monitoring the target control information within each target cycle in reference to the specified point in the time domain, thereby reducing the power consumption of the terminal and ensuring a high degree of operational availability.

[00191] In some optional embodiments of the present invention, the number of MBS services may be one or more; and when the number of MBS services is more than one, different MSB services will correspond to different reception configuration information.

[00192] In some optional embodiments of the present invention, the reception configuration information corresponding to the MBS includes at least one of the following elements: a monitoring cycle of the MBS service; a first timer for indicating a service monitoring duration in each monitoring cycle of the service; a service monitoring start point in each monitoring cycle of the service; a second timer for indicating that the network device has new data to be scheduled; a third timer for indicating to the terminal the need to perform HARQ feedback; or a fourth timer for indicating to the terminal the need to receive data retransmitted by the network device.

[00193] In some optional embodiments of the present invention, it is provided that when the terminal determines that the initial tracking state starts MBS reception tracking, or when the terminal receives target control information for activating MBS reception tracking, the terminal can start MBS reception tracking. Accordingly, the terminal can perform at least one of the following operations:

[00194] starting at least one timer from among a first timer, a second timer, a third timer and a fourth timer;

[00195] start monitoring the control channel corresponding to the MBS; or

[00196] start monitoring the data transmission channel corresponding to MBS.

[00197] Starting to monitor the corresponding control channel includes, among other things, starting to monitor the PDCCH corresponding to the MBS. For example, the scheduling identifier corresponding to MBS #1 is G-RNTI-1, and the corresponding control channel is G-RNTI-1 PDCCH. The terminal can start monitoring the G-RNTI-1 PDCCH.

[00198] Starting to monitor a data transmission channel corresponding to an MBS includes, among other things, starting to monitor a PDSCH (physical downlink shared channel) corresponding to the MBS. For example, MBS #1 corresponds to performing data transmission via an SPS PDSCH-1, and the terminal may start monitoring the SPS PDSCH-1.

[00199] In some optional embodiments of the present invention, it is provided that when the terminal determines that the initial tracking state stops tracking the MBS reception, or when the terminal receives target control information for deactivating tracking the MBS reception, the terminal may stop tracking the MBS reception. Accordingly, the terminal may perform at least one of the following operations:

[00200] stopping or not starting at least one timer from among the first timer, the second timer, the third timer, and the fourth timer;

[00201] stop monitoring the control channel corresponding to the MBS;

[00202] stop monitoring the data transmission channel corresponding to the MBS.

[00203] The terminal may stop or start at least one of the above timers based on the reception configuration information corresponding to the MBS. In addition, the terminal may stop monitoring the control channel corresponding to the MBS, for example, stop monitoring the G-RNTI-1 PDCCH. The terminal may stop monitoring the data channel corresponding to the MBS, for example, stop monitoring the SPS PDSCH-1.

[00204] In the above-described embodiments of the present invention, the terminal may start or stop monitoring the MBS to avoid losing the MBS or wasting power by the terminal, while ensuring a high degree of operational availability.

[00205] In some optional embodiments of the present invention, the content of the target control information received by the terminal for activating or deactivating MBS reception tracking for the terminal includes, but is not limited to, at least one of the following elements:

[00206] MBS indicator information; or MBS activation state information;

[00207] The MBS indicator information may include, but is not limited to, at least one of the following: an MBS identifier (such as the MBS identifier described in the Background of the Present Invention section); or an MBS scheduling identifier.

[00208] In addition, the MBS scheduling identifier may include at least one of the following identifiers: a dynamic scheduling identifier, such as a G-RNTI; or a semi-persistent scheduling identifier, such as an SPS-RNTI.

[00209] The MBS activation state information may include, but is not limited to, at least one of the following: an activated state (or an "MBS reception tracking start" state); or a deactivated state (or an "MBS reception tracking stop" state).

[00210] The above description is for illustrative purposes only. Other types of target control information used to activate or deactivate MBS reception tracking for a terminal shall be within the scope of legal protection of the present invention.

[00211] Some optional embodiments of the present invention provide a method for controlling a switching of a tracking state, as shown in Fig. 7, which is a flow chart illustrating a method for controlling a switching of a tracking state according to one embodiment of the present invention, wherein the method may include performing the steps described below.

[00212] In step 701, the network device configures for the terminal the reception configuration information corresponding to the MBS and the initial tracking state corresponding to the MBS through an RRC message.

[00213] In step 702, the terminal starts MBS reception tracking based on the reception configuration information and the initial tracking state corresponding to the MBS.

[00214] In one embodiment of the present invention, for example, the initial tracking state is used to start tracking the reception of MBS. In practical application, the initial tracking state can also be used to stop tracking the reception of MBS.

[00215] At step 703, the network device transmits target control information to the terminal, wherein the target control information is used to deactivate MBS reception tracking for the terminal.

[00216] In this embodiment of the present invention, it is provided that if the initial tracking state stops tracking the MBS reception, then the target control information can be used to activate tracking the MBS reception for the terminal (not shown in Fig. 7).

[00217] At step 704, the terminal monitors the target control information at a target point in the time domain.

[00218] In step 705, the terminal stops monitoring the MBS reception based on the reception configuration information corresponding to the MBS and the indication in the monitored target control information.

[00219] In the above-described embodiments of the present invention, the network device may control the terminal to stop monitoring the reception of MBS by target control information when there is no MBS service to be transmitted, which reduces the power consumption of the terminal.

[00221] In step 801, the network device configures reception configuration information corresponding to the MBS for the terminal through an RRC message.

[00222] In step 802, the terminal does not start MBS reception tracking based on the reception configuration information corresponding to the MBS and the initial tracking state corresponding to the MBS agreed upon in the protocol.

[00223] In this embodiment of the present invention, for example, the initial tracking state agreed upon in the protocol stops tracking the reception of MBS. In practical application, the initial tracking state agreed upon in the protocol can also be used to start tracking the reception of MBS.

[00224] At step 803, the network device transmits target control information to the terminal, wherein the target control information is used to activate MBS reception tracking for the terminal.

[00225] In this embodiment of the present invention, it is provided that if the initial tracking state triggers MBS reception tracking, then the target control information can be used to deactivate MBS reception tracking for the terminal (not shown in Fig. 8).

[00226] At step 804, the terminal monitors the target control information at a target point in the time domain.

[00227] In step 805, the terminal initiates MBS reception tracking based on the reception configuration information corresponding to the MBS and the indication in the tracked target control information.

[00228] In the above-described embodiments of the present invention, the network device can control the terminal to start monitoring the reception of the MBS by target control information, which prevents the terminal from losing the MBS and reduces the power consumption of the terminal. In accordance with the above-described embodiments of the method for implementing application functions, the present invention also provides embodiments of the device for implementing application functions.
