Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a wireless communication method and apparatus, a terminal and a network device. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) is committed to the formulation of communication protocol standards, among which existing communication protocol standards have relevant records for multimedia broadcast multicast service (MBMS) in the communication process.

[0003] However, for multicast and / or broadcast service (MBS) services, there are mainly two transmission modes of the air interface between the network device and the terminal: multicast / broadcast and unicast. Among them, for unicast services, the transmission mode of the air interface between the network device and the terminal is unicast mode. Since a terminal in a connected state can receive multicast / broadcast services from a network device, and in some specific scenarios can also receive unicast services from a network device at the same time, further research is needed for scenarios where multiple types of services are received simultaneously. Summary of the invention

[0004] The embodiments of the present application provide a wireless communication method and apparatus, a terminal, and a network device, so as to enable the network side to know whether the terminal is interested in receiving MBS services and unicast services at the same time, thereby ensuring that the terminal can simultaneously receive MBS services and unicast services according to its own interests, and ensuring that the network side performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services.

In addition, the second network device can make a decision based on the interest information to determine whether to accept the terminal, and can also learn whether the terminal is interested in receiving MBS services and unicast services at the same time through the first indication information in the interest information, thereby ensuring that the second network device performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services, which is beneficial to improve the success rate of switching, improve network efficiency, and the performance of terminal receiving services. Or,

[0013] Since the first network device has received the interest information from the terminal, when the first network device decides to configure the terminal that is not in the dual-connection state as a dual-connection standby, or decides to change or modify the first network device to which the terminal in the dual-connection state is connected, the first network device can carry the interest information in the message (second message) between the master node and the second node in the dual-connection architecture, thereby sending the interest information in the dual-connection process through the second message. In addition, the third network device can make a decision based on the interest information to determine whether to accept the terminal, and can also learn whether the terminal is interested in receiving MBS services and unicast services at the same time through the first indication information in the interest information, thereby ensuring that the third network device performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services, which is beneficial to improving network efficiency and the performance of terminal receiving services.

[0041] Furthermore, the terminal can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can be deployed on the water surface (such as ships); it can also be deployed in the air (such as airplanes, balloons and satellites).

[0042] Furthermore, the terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in unmanned autonomous driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0043] Furthermore, the terminal may include a device with transceiver functions, such as a chip system, wherein the chip system may include a chip and may also include other discrete devices.

[0044] Specifically, the network device may be a device for communicating with a terminal, which is responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side. The network device may be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, a base transceiver station (BTS) in a GSM or CDMA communication system, a node B (NB) in a WCDMA communication system, an evolutionary node B (eNB or eNodeB) in an LTE communication system, a next generation evolved node B (ng-eNB) in an NR communication system, a next generation node B (gNB) in an NR communication system, a master node (MN) in a dual-link architecture, a second node or a secondary node (SN) in a dual-link architecture, etc., without specific limitation.

[0047] Furthermore, the network device can communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0048] It should be noted that in some network deployments, the network device can be an independent node to implement all the functions of the above-mentioned base station, which may include a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU; it may also include an active antenna unit (AAU). Among them, the CU can implement some functions of the network device, and the DU can also implement some functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, RF processing, and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, under this network deployment, high-level signaling (such as RRC layer signaling) can be considered to be sent by the DU, or sent by the DU and the AAU together. It can be understood that the network device may include at least one of the CU, DU, and AAU. In addition, the CU can be classified as a network device in the access network (radio access network, RAN), or the CU can be classified as a network device in the core network, without specific limitation.

[0049] Furthermore, the network device may have a mobile feature, for example, the network device may be a mobile device. Optionally, the network device may be a satellite or a balloon station.

[0050] Furthermore, the network device can provide services for the cell, and the terminal in the cell can communicate with the network device through transmission resources (such as spectrum resources). The cell may include a macro cell, a small cell, a metro cell, a micro cell, a pico cell, and a femto cell.

[0051] In combination with the above description, an exemplary description of the wireless communication system of an embodiment of the present application is given below.

[0054] Optionally, the wireless communication system 10 may further include other network entities such as a network controller and a mobility management entity, which is not specifically limited.

[0055] Optionally, the communication between the network device and the terminal in the wireless communication system 10 may be wireless communication or wired communication, which is not specifically limited.

[0056] In combination with the above description, before introducing the wireless communication method provided in the embodiment of the present application in detail, the relevant contents involved in the embodiment of the present application are introduced.

[0057] 1. Core Network

[0058] The core network of the embodiment of the present application is composed of core network network elements. Among them, the core network network element can also be called a core network device, which is a network element deployed in the core network. For example, a core network control plane network element or a core network user plane network element. The core network of the embodiment of the present application can be an evolved packet core network (EPC), a 5G core network (5G core network), or a new core network in a future communication system. For example, the 5G core network is composed of a group of network elements, and implements access and mobility management functions (AMF) such as mobility management, user plane functions (UPF) that provide functions such as packet routing and forwarding and QoS (Quality of Service) management, and session management functions (SMF) that provide functions such as session management, IP address allocation and management, etc. EPC can be composed of a mobility management entity (MME) that provides functions such as mobility management and gateway selection, a Serving Gateway (S-GW) that provides functions such as packet forwarding, and a PDN Gateway (P-GW) that provides functions such as terminal address allocation and rate control. For Multicast Broadcast Service (MBS), the core network may include several new network elements to implement functions such as data packet forwarding, MBS conference management, QoS management, transmission mode switching (switching between unicast and multicast / broadcast transmission modes), etc. Another way is that the functions can be implemented by existing core network elements.

[0059] 2. Uplink communication and downlink communication

[0060] In the embodiment of the present application, uplink communication can also be referred to as uplink transmission, which refers to the one-way communication from the terminal to the network device. Among them, the communication link used for uplink communication is the uplink. The data transmitted on the uplink is the uplink data. The transmission direction of the uplink data is the uplink direction. Similarly, downlink communication in the embodiment of the present application can also be referred to as downlink transmission, which refers to the one-way communication from the network device to the terminal. Among them, the communication link used for downlink communication is the downlink. The data transmitted on the downlink is the downlink data. The transmission direction of the downlink data is the downlink direction.

[0061] 3. Multimedia broadcast multicast service (MBMS)

[0062] MBMS service is a service introduced in 3GPP Release 6 (R6). MBMS service is a technology that transmits data from one data source to multiple terminals by sharing network resources. It can effectively utilize network resources while providing multimedia services and realize multimedia service broadcast and multicast at a higher rate (256kbps).

[0063] Since the MBMS spectrum efficiency in 3GPP R6 is low and insufficient to effectively carry the operation of mobile or TV type services, in the LTE communication system, 3GPP explicitly proposed to enhance the support capability for downlink high-speed multimedia broadcast and multicast services, and determined the design requirements for the physical layer and air interface.

[0064] Enhanced multimedia broadcast multicast service (E-MBMS) was introduced into the LTE communication system by 3GPP R9. E-MBMS proposed the concept of single frequency network (SFN), that is, using a unified frequency to send data in all cells at the same time, but ensuring synchronization between cells. This method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the spectrum efficiency will also be greatly improved accordingly, and the broadcast and multicast of services can be realized based on the IP multicast protocol.

[0065] In LTE / LTE-A, MBMS has only a broadcast bearer mode, but no multicast bearer mode. At the same time, the reception of MBMS services is applicable to terminals in the RRC connected state (RRC_CONNECTED) or the RRC idle state (RRC_IDLE).

[0066] In summary, for multicast / broadcast service (MBS) services, there are two main transmission modes of the air interface between network devices and terminals: multicast / broadcast and unicast. Since a terminal in a connected state can receive multicast / broadcast services from a network device, and in some specific scenarios can also receive unicast services from a network device at the same time, further research is needed for scenarios where multiple types of services are received simultaneously.

[0067] In combination with the above description, the present application embodiment provides a flow chart of a wireless communication method, please refer to Figure 2 , the method comprising:

[0068] S210. The terminal sends interest information to the first network device, where the interest information includes first indication information, and the first indication information is used to indicate whether the terminal is interested in receiving the MBS service and the unicast service at the same time.

[0069] It should be noted that, as to whether the terminal supports the simultaneous reception of MBS services and unicast services, currently, it is generally considered whether the terminal has the capability (capacity) to support simultaneous reception. Based on this, the embodiment of the present application further considers whether the terminal is interested in receiving simultaneously. Therefore, when the terminal reports interest information (InterestInformation or InterestMessage) for the MBS service to the first network device, the first network device can obtain information from the first indication information in the interest information whether the terminal is interested in receiving the MBS service and the unicast service at the same time, thereby ensuring that the terminal can simultaneously receive the MBS service and the unicast service according to its own interests, and ensuring that the first network device performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending the MBS service.

[0070] In addition, the first network device can be regarded as a network device described above, such as eNB, gNB, MN, SN, etc. It can be understood that in the dual-connection architecture, the terminal can report the interest information to the MN or SN. Among them, the MN can be a base station that has a control plane connection with the core network; the SN can be a base station that does not have a control plane connection with the core network.

[0071] In combination with the above description, the following embodiments of the present application will specifically illustrate the interest information.

[0072] In a possible example, the interest information may also include at least one of the following: second indication information, third indication information, a first list, and a second list; wherein the second indication information is used to indicate a multiplexing method for simultaneously receiving MBS services and unicast services, and the multiplexing method includes at least one of space division multiplexing, frequency division multiplexing, and time division multiplexing; the third indication information is used to indicate the wireless access technology RAT information of the MBS service that the terminal is interested in receiving; the first list is used to indicate a list of MBS services that the terminal is interested in receiving or is receiving; and the second list is used to indicate a frequency list of MBS services that the terminal is interested in receiving.

[0073] It should be noted that, in combination with the above description, the interest information sent by the terminal to the first network device in the embodiment of the present application may include at least one of the following:

[0074] →indication information (first indication information) for simultaneously receiving the MBS service and the unicast service; wherein, the simultaneous reception in the embodiment of the present application refers to reception in the same time unit, and the time unit includes one of a frame, a sub-frame, and a time slot; the indication information can be used to indicate whether the terminal is interested in or inclined to simultaneously receive the MBS service and the unicast service;

[0075] →indication information (second indication information) of a multiplexing mode of simultaneously receiving a unicast service of an MBS service; wherein the multiplexing mode of the embodiment of the present application may include space division multiplexing (SDM), frequency division multiplexing (FDM), and time division multiplexing (TDM); the indication information may be used to indicate a multiplexing mode in which the terminal is interested in simultaneously receiving an MBS service and a unicast service;

[0076] →Indication information (third indication information) for receiving RAT information of MBS services; wherein the RAT type of the embodiment of the present application may include wireless access technologies such as GSM, CDMA, WCDMA, GPRS, LTE, LTE-A, 5G NR, 6G, NTN, and 7G; the indication information may be used to indicate the RAT information of the MBS services that the terminal is interested in receiving; the RAT information is used to indicate the RAT required to be adopted for the MBS services that the terminal is interested in receiving;

[0077] → a list of MBS services that are of interest or being received (first list); wherein, in the embodiment of the present application, each MBS service in the MBS service list may be represented by a service identifier, and the service identifier may include a temporary mobile group identity (TMGI) or an IP address, etc.;

[0078] →A frequency list of MBS services that the terminal is interested in receiving (a second list); the frequency list can be used to indicate the frequencies of MBS services that the terminal is interested in receiving.

[0079] It can be seen that by the terminal reporting the above interest information, the network side can know whether the terminal is interested in receiving MBS services and unicast services at the same time, the multiplexing method, the RAT method and other information, so that the network side can perform reasonable resource allocation, resource scheduling, carrier aggregation configuration, etc., and ensure that the terminal can receive MBS services and unicast services at the same time according to its own interests.

[0080] In a possible example, the RAT information may include a RAT list or at least one RAT, and each RAT in the RAT list is sorted according to priority.

[0081] It is understandable that the above interest information may carry a RAT list or at least one RAT without priority sorting, and each RAT in the RAT list is sorted according to priority. Therefore, the network side can send the MBS services and unicast services that the terminal is interested in according to the RAT information, thereby ensuring the flexibility or diversity of system communication.

[0082] For example, the RAT list includes 5G NR and LTE, and 5G NR has a higher priority than LTE. Therefore, when the network side receives the RAT list, the network side can give priority to 5G NR to deliver the MBS services and unicast services that the terminal is interested in.

[0083] In a possible example, simultaneous reception refers to reception in the same time unit, where the time unit includes one of a frame, a subframe, and a time slot.

[0084] It can be understood that if the MBS service and the unicast service are received in the same frame, subframe or time slot, it means that the MBS service and the unicast service are received simultaneously.

[0085] In combination with the above description, the following embodiment of the present application will specifically illustrate the conditions for the terminal to report interest information.

[0086] In a possible example, the terminal sending the interest information to the first network device may include: when a reporting condition for the interest in the MBS service is met, the terminal sending the interest information to the first network device.

[0087] It should be noted that the embodiments of the present application also need to consider the conditions for the terminal to report interest in MBS services, to avoid the terminal reporting interest information anytime, anywhere or at an unknown time, thereby reducing signaling overhead and ensuring the stability and robustness of system communications.

[0088] Specifically, the reporting conditions may include at least one of the following:

[0089] → The terminal's interest information for the MBS service has changed; it is understandable that if the terminal's interest information for the MBS service has changed, the terminal may report the new (current) interest information to the first network device, thereby ensuring that the network device is aware of the new interest information of the terminal in a timely manner, and then performs relevant resource configuration, resource scheduling, etc. in a timely manner;

[0090] →The terminal successfully establishes a radio resource control RRC connection; it is understandable that if the terminal successfully establishes the RRC connection, the terminal can report the interest information to the first network device, thereby ensuring that the network device promptly learns the interest information of the terminal, and then promptly performs relevant resource configuration, resource scheduling, etc.;

[0091] →The terminal initiates one of RRC connection establishment, RRC connection reconstruction, RRC connection recovery, and RRC connection reconfiguration; it can be understood that if the terminal initiates an RRC connection (such as RRC connection establishment, RRC connection reconstruction, RRC connection recovery, or RRC connection reconfiguration), the terminal can report the interest information to the first network device, thereby ensuring that the network device promptly obtains the interest information of the terminal, and then promptly performs relevant resource configuration, resource scheduling, etc.;

[0092] →The terminal enters or leaves the area where MBS services are provided; it is understandable that if the terminal enters or leaves the area where MBS services are provided, it is necessary to switch the network device that provides MBS services, etc. Therefore, the terminal can report interest information to the first network device, so as to ensure that the network device timely learns the new (current) interest information of the terminal, and then timely performs relevant resource configuration, resource scheduling, switching decision (switching trigger, target cell selection), second node SN addition, etc.;

[0093] →The MBS service that the terminal is interested in receiving starts or stops being sent; It should be noted that the first network device will tell the terminal in advance when the MBS service that the terminal is interested in receiving starts or stops being sent (such as by configuring a timer, sending a system message, etc.). Therefore, when the MBS service that the terminal is interested in receiving starts or stops being sent, the terminal can report the interest information to the first network device, thereby ensuring that the network device is aware of the terminal's interest information in a timely manner, and then timely perform relevant resource configuration, resource scheduling, etc.;

[0094] →The relative priority between the MBS service and the unicast service that the terminal is interested in receiving changes; it can be understood that if the relative priority between the MBS service and the unicast service that the terminal is interested in receiving changes, the terminal can report the interest information to the first network device, so as to ensure that the network device timely learns the new (current) interest information of the terminal, and then timely performs relevant resource configuration, resource scheduling, etc.;

[0095] →The MBS service that the terminal is interested in receiving or is currently receiving changes; it is understandable that if the MBS service that the terminal is interested in receiving or is currently receiving changes, the terminal can report the interest information to the first network device, thereby ensuring that the network device is aware of the new (current) interest information of the terminal in a timely manner, and then promptly performs relevant resource configuration, resource scheduling, etc.

[0096] Furthermore, the interest information has changed, which may include at least one of the following:

[0097] →Whether the interest in receiving the MBS service and the unicast service at the same time has changed; it can be understood that if the terminal needs to receive the MBS service and the unicast service at the same time instead of not needing to receive the MBS service and the unicast service at the same time, the terminal can report the interest information to the first network device;

[0098] → The same time unit in which the MBS service and the unicast service are received at the same time is changed; it can be understood that if the MBS service and the unicast service are received in the same frame and the MBS service and the unicast service are received in the same time slot, the terminal can report the interest information to the first network device;

[0099] → The multiplexing mode of simultaneously receiving the MBS service and the unicast service with interest has changed; it can be understood that if the multiplexing mode of simultaneously receiving the MBS service and the unicast service is changed from time division multiplexing to frequency division multiplexing, the terminal can report the interest information to the first network device;

[0100] →The RAT information of the terminal interested in receiving MBS services has changed; it can be understood that if the RAT information includes a RAT list, and the number of RATs in the RAT list has changed, or the priority order between the RATs in the RAT list has changed, etc., the terminal can report the interest information to the first network device.

[0101] In combination with the above description, the following embodiments of the present application will specifically illustrate the method of transmitting or carrying interest information.

[0102] In a possible example, the interest information may be transmitted by an RRC message or a medium access control element MACCE.

[0103] It is understandable that the terminal can report the interest information to the first network device through an RRC message or a MAC CE.

[0104] Among them, the RRC message may include at least one of the following: RRCSetupRequest, RRCSetupComplete, RRCReconfigurationComplete, RRCResumeRequest, RRCResumeRequest1, RRCResumeComplete, RRCReestablishment, RRCReestablishmentComplete, UEAssistanceInformation, and MBSInterestIndication.

[0105] In combination with the above description, before S210, the method may further include: the terminal determines the first network device according to the preferentially selected first RAT, and the first RAT and the first network device have a corresponding relationship.

[0106] It should be noted that different network devices may support or provide different RATs, that is, the network devices and RATs have a corresponding relationship. Therefore, the terminal may preferentially select a RAT (ie, the first RAT) and then report the interest information to the network device corresponding to the RAT (ie, the first network device).

[0107] In addition, in the dual-connection architecture, if MN and SN correspond to the same RAT, the network side configures in advance whether the terminal reports to MN or SN, that is, the terminal determines the first network device from MN and SN according to the configuration information of the network configuration.

[0108] Among them, the first RAT may include one of the following: GSM, CDMA, WCDMA, GPRS, LTE, LTE-A, 5G NR, NTN, 6G.

[0109] It can be seen that in the embodiment of the present application, the terminal sends interest information to the first network device, and the interest information includes indication information for indicating whether the terminal is interested in receiving MBS services and unicast services at the same time, so that the first network device can obtain information through the first indication information in the interest information whether the terminal is interested in receiving MBS services and unicast services at the same time, thereby ensuring that the terminal can simultaneously receive MBS services and unicast services according to its own interests, and ensuring that the network side performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services.

[0110] Consistent with the above embodiment, the present application embodiment provides another wireless communication method, see Figure 3 , the method comprising:

[0111] S310. The first network device receives interest information from a terminal, where the interest information includes first indication information, and the first indication information is used to indicate whether the terminal is interested in receiving an MBS service and a unicast service simultaneously.

[0112] S320: If the first network device decides to switch the terminal to the second network device, the first network device sends a first message to the second network device, where the first message carries interest information and is used to request to switch the terminal to the second network device.

[0113] It should be noted that, firstly, the decision of the first network device to switch the terminal to the second network device can be understood as that the first network device can determine whether the terminal needs to be switched to the second network device according to the measurement report reported by the terminal.

[0114] Secondly, the first network device may be a source node for the terminal to switch, and the second network device may be a target node for the terminal to switch.

[0115] Finally, since the first network device has received the interest information from the terminal, when the first network device decides to switch the terminal to the second network device, the first network device can carry the interest information in the message (first message) used to request the terminal to be switched to the second network device, thereby sending the interest information between network devices through the first message in the switching process. In addition, the second network device can make a decision based on the interest information to determine whether to accept the terminal, and can also learn whether the terminal is interested in receiving MBS services and unicast services at the same time through the first indication information in the interest information, thereby ensuring that the second network device performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services, which is conducive to improving the success rate of switching, improving network efficiency, and the performance of terminal receiving services.

[0116] In a possible example, the first message may be sent directly from the first network device to the second network device; or, the first message may be sent from the first network device to the second network device through the core network.

[0117] Specifically, the first message may include a handover request message, wherein the handover request message includes a HANDOVERREQUEST message or a HANDOVERREQUIRED message.

[0118] It can be understood that the HANDOVER REQUEST message is sent directly from the first network device to the second network device; and the HANDOVER REQUIRED message is sent from the first network device to the second network device via the core network.

[0119] It should be noted that the description of each embodiment in the present application has its own emphasis. Figure 3 For parts not described in detail in the embodiments, please refer to Figure 2 The relevant description in the above-mentioned embodiment will not be repeated here.

[0120] The following embodiments of the present application further Figure 3 The embodiments described are for illustration purposes only.

[0121] Example 1:

[0122] First, base station 1 receives interest information for MBS services reported by the terminal.

[0123] Secondly, base station 1 decides to handover the terminal to the cell of base station 2, that is, base station 1 and base station 2 prepare for handover.

[0124] Again, base station 1 sends message 1 to base station 2. Message 1 carries the interest information; message 1 may be sent directly from base station 1 to base station 2, or may be sent to base station 2 through the core network; message 1 may be a HANDOVER REQUEST message or a HANDOVER REQUIRED message.

[0125] Finally, base station 2 receives the interest information, and can thereby obtain the indication information, multiplexing method, RAT method and other information of the terminal simultaneously receiving MBS services and unicast services through the interest information, and can decide whether to accept the terminal, and can also perform operations such as resource configuration, scheduling strategy, and carrier aggregation configuration for MBS sending.

[0126] In a possible example, the interest information also includes at least one of the following: second indication information, third indication information, a first list, and a second list; wherein the second indication information is used to indicate that the terminal is interested in receiving a multiplexing mode of MBS services and unicast services at the same time, and the multiplexing mode includes at least one of space division multiplexing, frequency division multiplexing, and time division multiplexing; the third indication information is used to indicate the wireless access technology RAT information of the MBS service that the terminal is interested in receiving; the first list is used to indicate a list of MBS services that the terminal is interested in receiving or is receiving; and the second list is used to indicate a frequency list of MBS services that the terminal is interested in receiving.

[0127] In a possible example, the RAT information includes a RAT list or at least one RAT, and each RAT in the RAT list is sorted according to priority.

[0128] In a possible example, simultaneous reception refers to reception in the same time unit, where the time unit includes one of a frame, a subframe, and a time slot.

[0129] In a possible example, S310 specifically includes: when a reporting condition for interest in the MBS service is met, the first network device receives interest information from the terminal.

[0130] In a possible example, the reporting conditions include at least one of the following: the terminal's interest information for the MBS service changes; the terminal successfully establishes a radio resource control RRC connection; the terminal initiates one of RRC connection establishment, RRC connection reconstruction, RRC connection recovery, and RRC connection reconfiguration; the terminal enters or leaves an area providing MBS services; the MBS service that the terminal is interested in receiving starts or stops being sent; the relative priority of the MBS service and unicast service that the terminal is interested in receiving changes; the MBS service that the terminal is interested in receiving or is receiving changes.

[0131] In one possible example, the interest information has changed, including at least one of the following: whether to simultaneously receive MBS services and unicast services has changed; the same time unit for simultaneously receiving MBS services and unicast services has changed; the multiplexing method for simultaneously receiving MBS services and unicast services has changed; the RAT information for simultaneously receiving MBS services has changed.

[0132] In a possible example, the interest information is transmitted by an RRC message or a medium access control element MAC CE.

[0133] In a possible example, the first network device is determined by the terminal according to a preferred first RAT, and the first RAT has a corresponding relationship with the first network device.

[0134] Consistent with the above embodiment, the present application embodiment provides another wireless communication method, see Figure 4 , the method comprising:

[0135] S410. A first network device receives interest information from a terminal, where the interest information includes first indication information, and the first indication information is used to indicate whether the terminal is interested in receiving an MBS service and a unicast service simultaneously.

[0136] S420. If the first network device decides to configure a terminal that is not in a dual-connection state as a dual-connection, or decides to change or modify the first network device to which the terminal in a dual-connection state is connected, the first network device sends a second message to the third network device. The second message carries interest information. The second message is a message between a master node and a second node in a dual-connection architecture.

[0137] It should be noted that, first of all, for the first network device to decide to configure a terminal that is not in a dual-connection state as a dual-connection, it can be understood that the first network device can determine whether it is necessary to configure the terminal as a dual-connection based on the measurement results of the radio resource management (RRM) reported by the terminal that is not in a dual-connection state.

[0138] Secondly, for the first network device to decide to change or modify the network device connected to the terminal in the dual connection state, it can be understood that the first network device is connected to the terminal in the dual connection state, and the first network device can determine whether it is necessary to change or modify the first network device connected to the terminal based on the measurement results of the radio resource management (radio resource management, RRM) reported by the terminal in the dual connection state.

[0139] Again, the first network device may be a master node of a dual-connection architecture or a second node of a dual-connection architecture, and the third network device may be a master node of a dual-connection architecture or a second node of a dual-connection architecture. It is understandable that if the first network device is an MN, the third network device is an SN; if the first network device is an SN, the third network device is an MN, and there is no specific limitation on this.

[0140] Finally, since the first network device has received the interest information from the terminal, when the first network device decides to configure the terminal that is not in the dual-connection state as a dual-connection standby, or decides to change or modify the first network device to which the terminal in the dual-connection state is connected, the first network device can carry the interest information in the message (second message) between the master node and the second node in the dual-connection architecture, thereby sending the interest information in the dual-connection process through the second message. In addition, the third network device can make a decision based on the interest information to determine whether to accept the terminal, and can also learn whether the terminal is interested in receiving MBS services and unicast services at the same time through the first indication information in the interest information, thereby ensuring that the third network device performs resource configuration, resource scheduling, carrier aggregation configuration, etc. for sending MBS services, which is beneficial to improving network efficiency and the performance of terminal receiving services.

[0141] Specifically, the second message may include one of a second node addition request message (S-NODE ADDITION REQUEST), a second node change request message (S-NODE CHANGE REQUIRED), a second node modification request message (S-NODEMODIFICATION REQUIRED or S-NODE MODIFICATION REQUEST), and a second node change rejection message (S-NODE CHANGE REFUSE).

[0142] It should be noted that the description of each embodiment in the present application has its own emphasis. Figure 4 For parts not described in detail in the embodiments, please refer to Figure 2 or Figure 3 The relevant description in the above-mentioned embodiment will not be repeated here.

[0145] First, base station 1 receives interest information for MBS services reported by the terminal.

[0146] Secondly, base station 1 decides to configure the terminals that are not in the dual connection state as dual connection.

[0147] Again, base station 1 sends message 2 to base station 3. Message 2 carries the interest information; message 2 is a message between MN and SN, which may include S-NODE ADDITION REQUEST.

[0148] Finally, base station 3 receives the interest information, and can thereby obtain the indication information, multiplexing method, RAT method and other information of the terminal simultaneously receiving MBS services and unicast services through the interest information, and can decide whether to accept the terminal, and can also perform operations such as resource configuration, scheduling strategy, and carrier aggregation configuration for MBS sending.

[0149] Example 3:

[0150] First, base station 1 receives interest information for MBS services reported by the terminal, where base station 1 is SN.

[0151] Secondly, base station 1 decides to change or modify the base station 1 to which the terminal in the dual connection state is connected.

[0152] Again, base station 1 sends message 3 to base station 4. Base station 4 is MN; message 3 carries the interest information; message 3 is a message between SN and MN, which may include S-NODE CHANGE REQUIRED and S-NODE MODIFICATION REQUIRED.

[0153] Finally, base station 4 receives the interest information, and can thereby obtain the indication information, multiplexing method, RAT method and other information of the terminal simultaneously receiving MBS services and unicast services through the interest information, and can also perform operations such as resource configuration, scheduling strategy, and carrier aggregation configuration for MBS sending.

[0154] Example 4:

[0155] First, base station 1 receives interest information for MBS services reported by a terminal, wherein base station 1 is a MN.

[0156] Secondly, base station 1 decides to change or modify the base station 1 to which the terminal in the dual connection state is connected.

[0157] Again, base station 1 sends message 4 to base station 5. Base station 5 is SN; message 4 carries the interest information; message 4 is a message between MN and SN, which may include S-NODE MODIFICATION REQUEST and S-NODE CHANGEREFUSE.

[0158] Finally, the base station 5 receives the interest information, and can thereby obtain the indication information, multiplexing method, RAT method and other information of the terminal simultaneously receiving MBS services and unicast services, and can also perform operations such as resource configuration, scheduling strategy, and carrier aggregation configuration for MBS transmission.

Or,

[0182] Since the wireless communication device has received the interest information from the terminal, when deciding to configure a terminal that is not in a dual-connection state as a dual-connection standby, or deciding to change or modify the first network device to which the terminal in a dual-connection state is connected, the wireless communication device can carry the interest information in the message (second message) between the master node and the second node in the dual-connection architecture, thereby sending the interest information in the process of configuring the dual connection through the second message.
