Abstract

This application provides a method, network device, and user equipment for reporting MBS (Multicast Broadcast Service) interests. It proposes a scheme whereby the network device sends first configuration information for MBS interest reporting to the UE. This first configuration information indicates the RRC (Relationship Control Code) state range of the UE that needs to report MBS interests. The RRC state range includes a non-RRC connected state. The UE determines whether to report MBS interests to the network device based on its RRC state and the RRC state range indicated by the first configuration information. This ensures that even when the UE is in a non-connected state, it still needs to report MBS interest information to the network device according to the configuration information. This effectively guarantees that the network device can statistically analyze the MBS interests of the UE in different RRC states, and then dynamically control the MBS service area based on the statistical results, improving control accuracy and ensuring the continuity of the UE's MBS service.

Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method for reporting interests in Multicast Broadcast Service (MBS), network equipment, and user equipment. Background Technology

[0002] Multicast Broadcast Service (MBS) is a service that transmits data from one data source to multiple user devices, enabling the sharing of network resources. MBS includes both multicast and broadcast services, both of which are transmitted within a specific service area.

[0003] In existing technologies, to improve the utilization efficiency of wireless resources, network devices control the size of the service area for MBS services and whether to enable MBS services within that service area. Specifically, the network device collects the number of UEs interested in MBS services and then controls the service area of ​​the MBS service based on this number of UEs.

[0004] However, research has revealed that, under the current method, network devices have control biases when controlling the service area of ​​MBS services based on the number of UEs, which in turn affects the continuity of MBS services for UEs. Summary of the Invention

[0056] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0057] In existing technologies, UEs only report MBS interest information to the network device when they are in RRC connected state; UEs not in RRC connected state do not report MBS interest. This can lead to discrepancies between the number of UEs reported by the network device as interested in MBS services and the actual situation. Because the network device cannot accurately obtain the MBS interests of UEs in different RRC states, it cannot accurately and dynamically control the service area of ​​MBS services based on the number of UEs, thus affecting the continuity of MBS services for UEs.

[0058] This application provides an MBS interest reporting method, a network device, and a user equipment, which enables the network device to send first configuration information to UEs in different RRC states, so that UEs in different RRC states can report MBS interests according to the RRC state range indicated by the first configuration information, thereby enabling the network device to dynamically control the service area of ​​MBS services based on the MBS interest information of UEs in different RRC states.

[0059] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0060] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0061] Figure 1 This application provides a network architecture, such as... Figure 1 As shown, the network architecture includes user equipment and network equipment.

[0062] in, Figure 1 The user equipment in the context can be a device that provides voice and / or data connectivity to the user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem.

[0063] The user equipment involved in the embodiments of this application can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the user equipment may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network.

[0064] Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this application does not limit the terminology used in its embodiments.

[0065] The network device involved in this embodiment can be a base station, which may include multiple cells providing services to user equipment. Depending on the specific application, a base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0066] In the embodiments described in this application, network devices and terminal devices can each use one or more antennas to perform multiple input multiple output (MIMO) transmission, specifically multiple user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or it can be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0067] In such Figure 1 In the communication system shown, network devices carry MBS services. MBS services are transmitted within a certain MBS service area, also known as the MBS transmission area. The MBS service area can be static or dynamic.

[0068] When a static control method is used for the area, network devices within the service area belonging to the MBS service will continuously transmit broadcast or multicast services. This method has low resource utilization. For example, even when no UE is interested in the MBS service within the service area, or only a very small number of UEs are interested in the MBS service, the network devices will still continuously transmit MBS services, resulting in a waste of communication resources.

[0069] In contrast to static control, dynamic control can effectively improve resource utilization.

[0070] Specifically, under the existing communication architecture, especially the 5G NR architecture, the RRC state of a UE can include RRC connected state (connected mode), RRC idle state (non-connected mode), and RRC inactive state (idle mode). Generally, when a UE is powered on, it will be in the idle / inactive state. Based on the UE's activity, the UE will transition from the idle / inactive state to the connected state.

[0071] When a UE enters the MBS service area covered by the network device, the UE in the RRC connected state will receive the MBS service sent by the network device. At this time, the terminal will actively report its interest in the MBS service to the network. The network device can obtain the MBS interest reported by the UE and count the number of UEs. Based on the number of UEs, it can control relevant parameters such as whether to enable broadcast or multicast services in the MBS service area, or the size of the MBS service area, so that communication resources can be used rationally.

[0072] However, in existing technologies, not all UEs report MBS interest to the network device. Only UEs in RRC connected state report MBS interest to the network device, and the reason is as follows:

[0073] To ensure MBS service continuity, a UE receiving MBS services may experience a change in the serving cell due to mobility or other reasons. A UE needs to perform a serving cell handover only when it is in RRC connected mode. To ensure MBS service continuity, during the handover process, the source cell needs to prioritize handing the UE to a target cell that supports the current MBS service, based on the UE's interest in MBS, thus guaranteeing the continuity of MBS service reception. For UEs in non-RRC connected mode, such as those in idle / inactive mode, cell selection or cell reselection is required, which does not involve MBS service continuity issues.

[0074] For the reasons mentioned above, in the existing technology, only UEs in RRC connected state will report their interest in MBS services to the network device.

[0075] Although the existing MBS interest reporting methods enable network devices to dynamically control MBS service requests, since only UEs in the RRC connected state report their interests, the network devices cannot know the interest of UEs in the idle / inactive state in MBS. This results in an inaccurate number of UEs interested in MBS obtained by the network devices, which in turn affects the dynamic control of the service area of ​​MBS services. It is easy for the size of the service area to be inconsistent with the actual UE needs, and it is also not conducive to the continuity of UE receiving MBS services.

[0076] Based on this, in this application, the network device can carry the RRC status range of the UE that needs to report MBS interest in the RRC message or DCI information and send it to all UEs in its service area. Since the message or information can be received by UEs in various RRC states, the UE that receives the first configuration information will report MBS interest according to its own RRC status and the RRC status range indicated by the first configuration information. This enables the network device to dynamically control the service area of ​​MBS service based on the MBS interest information of UEs in different RRC states.

[0077] The embodiments of this application will now be described in detail with reference to the accompanying drawings and the steps provided above.

[0078] Example 1

[0079] Figure 2 This is a flowchart illustrating a method for reporting interests in a multicast broadcast service (MBS) provided in this application. Figure 2 The execution entity of the method shown is Figure 1 User terminals in a network architecture.

[0080] Combination Figure 2 The multicast broadcast service (MBS) interest reporting method provided in this embodiment includes:

[0081] Step 201: Obtain first configuration information for MBS interest reporting. The first configuration information includes the RRC state range for indicating the UE that needs to perform MBS interest reporting. The RRC state range includes non-RRC connected state.

[0082] Step 202: Based on the UE's RRC status and the RRC status range indicated by the first configuration information, determine whether to report MBS interest to the network device.

[0083] First, it should be clarified that since the communication system may include multiple user equipments, each user equipment that receives the first configuration information needs to execute the MBS interest reporting method provided in this embodiment. For different user equipments, the MBS interest reporting method can be executed synchronously or asynchronously; this application will not impose any restrictions on this.

[0084] In this embodiment, the network device can pre-configure first configuration information according to MBS requirements. This first configuration information at least indicates which UEs in which RRC states need to report MBS interests. To enable the network device to obtain the MBS interests of UEs in various RRC states, in this embodiment, the RRC state range includes at least non-RRC connected states. That is, when a UE is in a non-RRC connected state, it needs to report MBS interests.

[0085] For example, when the first configuration information indicates that a UE in RRC idle state or RRC inactive state needs to report MBS interests, after the UE obtains the first configuration information, it will first determine its current RRC state, and then determine whether the current RRC state of the UE belongs to the RRC state range indicated by the first configuration information. If the current UE is in RRC inactive state, it is determined that it falls within the RRC state range of UEs that need to report MBS interests. At this time, the UE needs to report MBS interests.

[0086] If the UE's RRC status does not fall within the RRC status range indicated by the first configuration information, then MBS interest reporting will not be performed to the network device.

[0087] In this way, the UE that receives the first configuration information will report MBS interest based on its own RRC status and the RRC status range indicated by the first configuration information. This enables the network device to dynamically control the service area of ​​MBS services based on the MBS interest information of the UE under different RRC statuses.

[0088] Optionally, the first configuration information recorded in this application embodiment may include, in addition to the RRC status range for indicating the UE that needs to report MBS interests, service information for indicating the MBS service that needs to report MBS interests, wherein the service information includes service type and / or MBS service identifier; session identifier for indicating the MBS session that needs to report MBS interests; and at least one or more of the control identifiers for indicating whether to report MBS interests.

[0089] Based on the above implementation methods, the first configuration information may further include the MBS service scope that needs to be reported for MBS interest. The following implementation methods describe the interest reporting methods of the first configuration information for MBS service scopes at different granularities.

[0090] In one optional implementation, the first configuration information may be applicable to all MBS services within the cell; based on this, step 202 may specifically include: when the current UE's RRC state falls within the RRC state range indicated by the first configuration information, reporting MBS interest to the network device for all MBS services of interest.

[0091] In this implementation, since the UE will obtain the first configuration information sent by the network device of the cell where the UE is located, when the first configuration information indicates that all MBS services need to report interest, it means that if the UE is within the cell range and the UE's RRC state falls within the range of RRC states of UEs that need to report interest, then regardless of which MBS service the UE is interested in, the UE needs to report MBS interest for the MBS service it is interested in.

[0092] In another optional implementation, the first configuration information further includes service information indicating the MBS services for which MBS interest reporting is required, wherein the service information includes service type and / or MBS service identifier. Based on this, step 202 may specifically include: if the UE's RRC state falls within the RRC state range indicated by the first configuration information, then, based on the service information of the MBS services the UE is interested in and the service information of the MBS services for which MBS interest reporting is required indicated by the first configuration information, determining whether to report MBS interest to the network device.

[0093] MBS service types include broadcast and multicast types. In this implementation, the first configuration information indicates that the UE needs to report its interest in broadcast and / or multicast MBS services.

[0094] In other words, if the UE's RRC status falls within the range of UEs that need to report their interests, the UE will compare the MBS service type it is interested in with the type range indicated by the first configuration information, and report its MBS interest when the MBS service type it is interested in falls within the type range indicated by the first configuration information.

[0095] MBS service identifier refers to the identifier of a specific MBS service. This identifier is used to distinguish different MBS services. MBS services generally refer to application layer services, such as video services, audio services, etc.

[0096] Similar to the aforementioned embodiments, if the RRC status of the UE falls within the RRC status range of the UE that needs to report interest, the UE will compare the MBS service identifier it is interested in with the range of MBS service identifiers indicated by the first configuration information, and report MBS interest when the identifier of the MBS service it is interested in falls within the range of identifiers indicated by the first configuration information.

[0097] Similarly, in other optional implementations, the first configuration information further includes a session identifier for indicating the MBS session that needs to be reported for MBS interest. Based on this, step 202 may specifically include: if the UE's RRC state falls within the RRC state range indicated by the first configuration information, then, based on the session identifier of the MSB session of interest to which the UE is interested and the session identifier of the MSB session that needs to be reported for MBS interest as indicated by the first configuration information, determining whether to report MBS interest to the network device.

[0098] The session identifier of the MSB session is used to distinguish different MBS sessions. The MBS session can specifically represent the path of MBS services, such as a video service session, an audio service session, etc.

[0099] Similar to the aforementioned embodiments, if the RRC state of the UE falls within the RRC state range of the UE that needs to report interest, the UE will compare the session identifier of the MSB session it is interested in with the session identifier of the MSB session indicated by the first configuration information, and perform MBS interest reporting when the session identifier of the MSB session it is interested in falls within the session identifier indicated by the first configuration information.

[0100] Meanwhile, the first configuration information can be carried in different messages and sent to the UE by the network device at different stages for the UE to obtain.

[0101] In one alternative implementation, the first configuration information may be carried in the downlink control information (DCI) of the physical layer and sent to the UE by the network device when scheduling the MCCH. That is, the UE receives the downlink control information (DCI) sent by the network device and obtains the first configuration information for MBS interest reporting from the DCI.

[0102] Specifically, since DCI can carry a limited number of information bits, this transmission method can only be used when the first configuration information mentioned above carries a relatively small number of information bits.

[0103] For example, when the first configuration information applies to all MBS services, or when the first configuration information is also used to indicate the type of MBS service that needs to report MBS interest, the information bits carried in the first configuration information are relatively few. In this case, the network device can use the downlink control information (DCI) of the physical layer to carry the first configuration information so that the UE can receive the information.

[0104] After the UE obtains the first configuration information through DCI, since the first configuration information is obtained at the physical layer, the UE will also report the first configuration information of MBS interest reporting obtained at the physical layer to the RRC layer for subsequent processing.

[0105] In another optional implementation, the UE receives an RRC message sent by the network device and reads the first configuration information of MBS interest reporting from the RRC message. Specifically, the first configuration information may also be carried in the RRC message at the RRC layer and sent to the UE by the network device when sending system messages or MBS control messages on the MCCH or other RRC messages.

[0106] Because the RRC message of the RRC layer has a relatively wide requirement for the number of information bits, it can carry a large number of bits. Therefore, this sending method has no restrictions on the content indicated in the first configuration information.

[0107] Based on the above implementation methods, while the network device instructs the UE to initiate MBS interest reporting for certain MBS service ranges via the first configuration information, it can also instruct the UE to stop MBS interest reporting for certain MBS service ranges. There are two ways to implement stopping or suspending interest reporting:

[0108] In an optional implementation, the first configuration information further includes a control identifier for indicating whether to report MBS interests; the UE starts or stops reporting MBS interests to the network device according to the control identifier in the first configuration information.

[0109] In other words, the first configuration information also includes a control identifier for indicating whether MBS interest reporting should be performed. This control identifier indicates whether the UE needs to initiate MBS interest reporting or stop MBS interest reporting. Accordingly, if the UE's RRC state falls within the RRC state range indicated by the first configuration information, then if the control identifier indicates that it is enabled, MBS interest will be reported to the network device; if the control identifier indicates that it is disabled, MBS interest will not be reported to the network device.

[0110] Of course, in an optional implementation, the control identifier can be combined with the aforementioned MBS services that need to be reported so that the UE can start or stop interest reporting for different MBS services. In other words, the first configuration information can be used to instruct the UE to report interest in some MBS services or to instruct the UE to stop reporting interest in other MBS services.

[0111] In this way, the UE that receives the first configuration information will perform MBS interest reporting based on its own RRC status and the control identifier indicated by the first configuration information.

[0112] In another alternative implementation, the network device may also update the first configuration information to obtain second configuration information, which includes the RRC status range for indicating UEs that need to suspend MBS interest reporting.

[0113] After obtaining the second configuration information for suspending MBS interest reporting, the UE will determine whether to suspend MBS interest reporting to the network device based on the current UE's RRC status and the RRC status range indicated by the second configuration information.

[0114] For the second configuration information, the first configuration information and the second configuration information can be carried in the same downlink control information.

[0115] In other words, network devices can send first configuration information and second configuration information simultaneously in the same message, so that the UE receiving the information can perform corresponding interest reporting based on the first configuration information and the second configuration information.

[0116] In an optional implementation, the first configuration information and the second configuration information are carried in the same message at the RRC layer.

[0117] The second configuration information can also provide pause instructions for different granularities of service scope. Its implementation is similar to that of the first configuration information in the aforementioned embodiment, and will not be described in detail here.

[0118] The MBS interest reporting method provided in this application proposes a scheme whereby the network device sends first configuration information for MBS interest reporting to the UE. This first configuration information includes the RRC state range of the UE that needs to report MBS interests, including a non-RRC connected state. The UE determines whether to report MBS interests to the network device based on its current RRC state and the RRC state range indicated by the first configuration information. This ensures that even when the UE is in a non-connected state, it still needs to report MBS interest information to the network device according to the configuration information. This effectively guarantees that the network device can statistically analyze the MBS interests of the UE in different RRC states, and then dynamically control the MBS service area based on the statistical results, improving control accuracy and ensuring the continuity of the UE's MBS services.

[0123] Step 302: Receive MBS interest information sent by the UE according to the first configuration information.

[0125] Network devices can pre-configure first configuration information based on MBS requirements. This first configuration information includes at least information indicating which UEs in which RRC states need to report MBS interests. The RRC state range includes at least non-RRC connected states.

[0126] Then, the network device can include the first configuration information in the RRC message or DCI information when sending it to the UE. Figure 4 (Taking DCI information as an example).

[0127] The physical layer on the UE side obtains the MBS interest reporting configuration information from the corresponding DCI and reports it to the RRC layer on the UE side.

[0128] The UE will obtain the first configuration message and determine whether MBS interest reporting is required based on the current UE's RRC status.

[0129] Finally, optionally, after obtaining MBS interests reported by different UEs, the network device will perform dynamic control over the MBS service area.

[0130] This approach allows network devices to generate first configuration information as needed. By indicating in this first configuration information that UEs in non-RRC states also need to report MBS interests, non-RRC state UEs receiving this first configuration information will perform MBS interest reporting accordingly. In this way, network devices can obtain MBS interest information from UEs in non-RRC states, thereby improving the accuracy of dynamic control over the service area.

[0131] Optionally, the first configuration information recorded in this embodiment is generated by the network device according to requirements. In addition to including the RRC status range of the UE, it may also include the RRC status range of the UE that needs to report MBS interests; it may also include service information that indicates the MBS service that needs to report MBS interests, wherein the service information includes service type and / or MBS service identifier; session identifier that indicates the MBS session that needs to report MBS interests; and control identifier that indicates whether to report MBS interests.

[0132] Similar to the aforementioned embodiments, based on the above implementation methods, the first configuration information may further include the MBS service scope that requires MBS interest reporting. The following embodiments describe interest reporting methods for MBS service scopes at different granularities using the first configuration information.

[0133] In one alternative implementation, the first configuration information may be applicable to all MBS services within the cell; based on this, the network device will receive MBS interest reports from UEs whose RRC status falls within the RRC status range indicated by the first configuration information and who are interested in any one of the MBS services.

[0134] In this implementation, after the UE obtains the first configuration information sent by the network device of the cell where the UE is located, if the first configuration information indicates that all MBS services need to be reported for interest, that is, if the UE is within the cell range and the UE's RRC state falls within the range of UEs that need to report for interest, then regardless of which MBS service the UE is interested in, the UE needs to report the MBS interest for the MBS service it is interested in.

[0135] By acquiring MBS interest reports from such UEs, network devices can count the number of UEs in the service area interested in any MBS service, which facilitates dynamic control of the service area based on each MBS service.

[0136] In another optional implementation, the first configuration information further includes service information indicating the MBS services for which MBS interest reporting is required, wherein the service information includes a service type and / or an MBS service identifier. Based on this, the network device will receive MBS interest reports from UEs whose RRC status falls within the RRC status range indicated by the first configuration information, and which are interested in UEs whose service information includes a service type and / or an MBS service identifier.

[0137] MBS service types include broadcast and multicast types. In this implementation, the first configuration information indicates that the UE needs to report its interest in broadcast and / or multicast MBS services. The MBS service identifier is the identifier of a specific MBS service, used to distinguish different MBS services. MBS services generally refer to application layer services, such as video and audio services.

[0138] In other words, if the UE's RRC status falls within the range of UEs that need to report their interests, the UE will compare the MBS service type it is interested in with the range of types indicated by the first configuration information and / or the range of MBS service identifiers, and will report its MBS interest when the MBS service type and / or the MBS service identifier it is interested in falls within the range of types indicated by the first configuration information and / or the range of MBS service identifiers.

[0139] By acquiring MBS interest reports from such UEs, network devices can count the number of UEs in the service area who are interested in a specific MBS service type and / or a specific MBS service identifier, which facilitates dynamic control of the service area based on a specific MBS service type and / or a specific MBS service identifier.

[0140] Similarly, in other alternative implementations, the first configuration information further includes a session identifier for indicating the MBS session for which MBS interest reporting is required. Based on this, the network device will receive MBS interest reports from UEs whose RRC status falls within the RRC status range indicated by the first configuration information and who are interested in the session identifier of the MBS session included in the service information.

[0141] The session identifier of the MSB session is used to distinguish different MBS sessions. The MBS session can specifically represent the path of MBS services, such as a video service session, an audio service session, etc.

[0142] Similar to the aforementioned embodiments, if the RRC state of the UE falls within the RRC state range of the UE that needs to report interest, the UE will compare the session identifier of the MSB session it is interested in with the session identifier of the MSB session indicated by the first configuration information, and perform MBS interest reporting when the session identifier of the MSB session it is interested in falls within the session identifier indicated by the first configuration information.

[0143] By acquiring MBS interest reports from such UEs, network devices can count the number of UEs in the service area that are interested in a specific MBS session, which facilitates dynamic control of the service area based on specific MBS sessions.

[0144] Based on the above implementation methods, while the network device instructs the UE to initiate MBS interest reporting for certain MBS service ranges via the first configuration information, it can also instruct the UE to stop MBS interest reporting for certain MBS service ranges. There are two ways to implement stopping or suspending interest reporting:

[0145] In an optional implementation, the network device may also set a control identifier in the first configuration information to indicate whether to report MBS interests; the UE starts or stops reporting MBS interests to the network device according to the control identifier in the first configuration information.

[0146] In other words, by setting a control identifier in the first configuration information, the network device can use this control identifier to control the UE to start or stop reporting interest in MBS services. That is, if the network device needs to start interest reporting for UEs falling within the RRC state range indicated by the first configuration information, it can indicate that the control identifier is enabled; if the network device needs to stop interest reporting for UEs falling within the RRC state range indicated by the first configuration information, it can indicate that the control identifier is disabled.

[0147] Of course, in an optional implementation, the network device can also use the combination of the control identifier and the aforementioned MBS services that need to be reported to control the UE to start or stop interest reporting for different MBS services. That is, the first configuration information can be used to instruct the UE to report interest for some MBS or to instruct to stop reporting interest for other MBS.

[0148] This approach allows network devices to control the UE to start or stop interest reporting based on actual needs, and also facilitates subsequent dynamic control of the service area.

[0149] Based on the above implementation, for the first configuration information, the network device can carry it in different messages and send it to the UE at different stages for the UE to obtain. Optionally, the first configuration information is carried in the downlink control information (DCI) of the physical layer and sent to the UE. This enables the UE to receive the downlink control information (DCI) sent by the network device and obtain the first configuration information for MBS interest reporting from the DCI.

[0150] Specifically, since DCI can carry a limited number of information bits, this transmission method can only be used when the first configuration information mentioned above carries a relatively small number of information bits.

[0151] For example, when the first configuration information applies to all MBS services, or when the first configuration information is also used to indicate the type of MBS service that needs to report MBS interest, the information bits carried in the first configuration information are relatively few. In this case, the network device can use the downlink control information (DCI) of the physical layer to carry the first configuration information so that the UE can receive the information.

[0152] Based on the above implementation method, the network device can also send the first configuration information to the UE via RRC messages. Specifically, the network device can send the first configuration information to the UE along with system messages, MBS control messages on the MCCH, or other RRC messages.

[0153] Because the RRC message of the RRC layer has a relatively wide requirement for the number of information bits, it can carry a large number of bits. Therefore, this sending method has no restrictions on the content indicated in the first configuration information.

[0154] Based on the above implementation method, in other optional implementation methods, the network device may also update the first configuration information to control the UE to change its interest reporting method.

[0155] Optionally, the network device may update the first configuration information to obtain second configuration information, wherein the second configuration information includes the RRC status range for indicating UEs that need to suspend MBS interest reporting.

[0156] The network device can send a second configuration information to the UE to suspend MBS interest reporting, so that the UE that obtains the second configuration information can determine whether to suspend MBS interest reporting to the network device based on the RRC status range of the UE that needs to suspend MBS interest reporting as indicated by the second configuration information and the current RRC status of the UE.

[0157] The second configuration information can also provide pause instructions for different granularities of service scope, and its implementation is similar to that of the first configuration information in the aforementioned embodiments, so it will not be described in detail here. For the second configuration information, the first configuration information and the second configuration information can be carried in the same downlink control information.

[0158] In other words, network devices can send first configuration information and second configuration information simultaneously in the same message, so that the UE receiving the information can perform corresponding interest reporting based on the first configuration information and the second configuration information.

[0159] In an optional implementation, the first configuration information and the second configuration information are carried in the same message at the RRC layer.

[0160] The MBS interest reporting method provided in this embodiment is executed by a network device. The MBS interest reporting method provided in this embodiment is a corresponding method to the method involved in the first aspect. Its specific implementation is not much different from the method mentioned in the first aspect, and will not be described in detail here.

[0161] The MBS interest reporting method provided in this application proposes a scheme whereby the network device sends first configuration information for MBS interest reporting to the UE. This first configuration information indicates the RRC state range of the UE that needs to report MBS interest; the RRC state range includes a non-RRC connected state. The UE determines whether to report MBS interest to the network device based on its RRC state and the RRC state range indicated by the first configuration information. This ensures that even when the UE is in a non-connected state, it still needs to report MBS interest information to the network device according to the configuration information. This effectively guarantees that the network device can statistically analyze the MBS interests of the UE in different RRC states, and then dynamically control the MBS service area based on the statistical results, improving control accuracy and ensuring the continuity of the UE's MBS services.
