- the first terminal may maintain a timer. If the service data of the multicast service is not received in multicast mode during the running period of the timer, the first terminal may keep receiving the multicast service in the unicast mode. . For example, the first terminal starts the timer after receiving the unicast-to-multicast request. When the timer expires and the first terminal has not received the service data of the multicast service in the multicast mode, the first terminal judges the network If the device does not switch the multicast service from the unicast mode to the multicast mode, the first terminal can keep receiving the multicast service in the unicast mode, and does not continue to try to receive the multicast service in the multicast mode.

- the multicast service It is located in the service area of the multicast service, and when the second instruction information sent by the network device is received, the multicast service is received according to the unicast mode, and the second instruction information is used to indicate the unicast mode Receiving the multicast service.
- the second indication information is used to instruct the first terminal to receive the multicast service based on the unicast mode, so that the first terminal does not need to try to receive the multicast service in the multicast mode again, thereby ensuring that the first terminal and
- the network equipment has the same understanding, which reduces the power consumption of the first terminal.
- the unicast mode is always used to receive the multicast service. Further, when the first terminal located outside the multicast service area switches to be located in the multicast service area, it may also be triggered again to try to receive the multicast service in the multicast mode. In addition, in the embodiment of the present invention, all or part of the first terminals located in the multicast service area can be switched from the unicast mode to the multicast mode.
- Step 301 Provide a multicast service to the first terminal in a unicast manner.
- the number of users receiving the multicast service 1 is small, and the content provider (Content Provider) provides the multicast service to multiple first terminals in a unicast manner.
- Step 302 The second terminal initiates a multicast session establishment request.
- the second terminal if the second terminal is interested in a certain multicast service, it can initiate a multicast session establishment request.
- the multicast service 1 is being provided in a unicast manner, and the new user terminal (ie, the second terminal) detects that it is in the service area of the multicast service, and initiates a multicast session establishment process to request to join the multicast session.
- the second terminal may send a multicast session establishment request message, and the multicast session establishment request message may carry multicast service information (for example, Multicast IP or Multicast Group Identifier (Temporary Mobile Group Identifier, TMGI)); second The terminal can also send a unicast session establishment request message.
- the unicast session establishment request message carries multicast service information to indicate a multicast session establishment request.
- the unicast session establishment request message can be understood as a PDU session establishment request message (PDU Session Establishment Request). Request).
- the content provider decides to convert a certain multicast service from a unicast providing mode to a multicast providing mode. For example, it is judged by counting the total number of terminals that are receiving or requesting to receive the multicast service. If the total number of users exceeds a preset threshold, it is determined to switch from a unicast mode to a multicast mode.
- MBS Multicast Broadcast Service
- Step 304 The content provider requests the first terminal that is receiving the multicast service in a unicast manner to switch from the unicast reception mode to the multicast reception mode.
- the request information may be requested through application layer data.
- Step 305 The first terminal receiving the unicast mode detects whether it is in the service area of the multicast service. For example, the first terminal judges whether the cell provides the multicast service by detecting the system messages of the surrounding cells. If the cell system information indicates that it provides the multicast service, the first terminal determines that it is within the service area of the multicast service, otherwise it is not within the service area of the multicast service.
- Step 306 Optionally, if the first terminal receiving the unicast mode detects that it is in the service area of the multicast service, it initiates a multicast session establishment process. For example, if the first terminal is in the service area of the multicast service, but the multicast link of the multicast service has not been established, the first terminal initiates a multicast session establishment process to request the establishment of a multicast channel.
- Step 307 Optionally, if the first terminal detects that it is in the service area of the multicast service, it responds to the mode switching request. For example, if the first terminal is in the service area of the multicast service and receives a mode switching request for switching from unicast to multicast, it will reply that it agrees to switch the unicast receiving mode to the multicast receiving mode, and the first terminal can use the application The layer (such as the IP message) replies to the mode switching request.
- the layer such as the IP message
- step 308 the content provider receives the mode switching response of the first terminal, and judges whether to officially switch from unicast to multicast. For example, based on the total number of received mode switching responses, if the total number exceeds a preset threshold, it is formally determined to switch from unicast to multicast.
- Step 309 The first terminal receives the multicast service data in a unicast mode, and at the same time waits for the multicast service data to be received in a multicast mode.
- the first terminal receives in a specific time-frequency position according to the multicast receiving method provided by the network side (for example, the cell that can provide the multicast service indicates the method of receiving the multicast service in the system message, and the first terminal reads the cell’s The system message learns how to receive data) to receive multicast service data.
- step 310 if the multicast service data is received in the multicast mode, the protocol data unit session or the radio resource control connection is released. If the first terminal receives multicast data at a specific time-frequency location through the multicast service receiving method provided by the network side, the first terminal determines that the network device has converted the multicast service from the unicast service mode to the multicast service mode , The PDU session release process is initiated to request the release of the unicast link. In addition, the first terminal initiates an RRC connection release process to request to enter the idle state. For example, the first terminal does not need to receive other unicast services other than the multicast service, and then requests to release the RRC connection to enter the idle state.
- the first terminal may also maintain a timer. If the multicast data is not received in the multicast mode during the running period of the timer, the first terminal still remains in the unicast receiving mode. For example, after the first terminal sends a mode switch response request, it starts a timer. When the timer expires and the first terminal has not received multicast data in multicast, the first terminal determines that the network device does not provide unicast data. When the mode is switched to the multicast providing mode, the first terminal continues to remain in the unicast receiving mode, and does not try to receive the multicast data in the multicast mode.
- the network device may instruct the first terminal to switch the multicast service from the unicast mode to the multicast mode, and the first terminal initiates the PDU session release process to request the release of the unicast link or initiate the RRC connection release process Request to enter idle state.
- the network device instructs the first terminal to formally convert the remaining multicast service from the unicast providing mode to the multicast providing mode, the first terminal may release the unicast link of the multicast service and receive the multicast service in the multicast mode.
- the first terminal if the network device instructs the first terminal to continue to provide the multicast service in the unicast mode, the first terminal continues to receive the multicast service in the unicast mode. For example, if the network device instructs the first terminal to continue to provide the remaining multicast services in the unicast mode, the first terminal continues to receive unicast services, and does not attempt to receive in the multicast mode, for example, no longer detects the location of the multicast resources.
- FIG. 4 is a flowchart of a multicast service transmission processing method provided by an embodiment of the present invention. The method is applied to a network device, as shown in FIG. 4, and includes the following steps:
- Step 401 Send a unicast-to-multicast request for a multicast service to a first terminal, where the unicast-to-multicast request is used to trigger the first terminal to receive the multicast service according to a target mode, and the target mode includes Unicast mode and/or multicast mode.

针对上述方式4，网络设备可以统计多播业务的终端的总量，在总量大于第三预设值时，将会触发网络设备向第一终端发送单播转多播请求。
需要说明的是，在一些实施例中，还可以结合两个方式进行确定，例如，可以基于上述方式1和方式3，或者基于方式1和方式4。换句话说，在满足方式1和方式3对应的条件时，触发网络设备向第一终端发送单播转多播请求；或者在满足方式1和方式4对应的条件时，触发网络设备向第一终端发送单播转多播请求。
可选的，第一终端可以基于单播转多播请求，决定按照目标模式接收所述多播业务。本实施例中，按照目标模式接收所述多播业务可以理解为按照目标模式接收该多播业务的剩余业务数据(或者说剩余多播业务)。
在一实施例中，可以继续保持以单播模式接收该多播业务，也可以同时按照多播模式和单播模式接收该多播业务，还可以仅按照单播模式接收多播业务。应理解，按照多播模式接收多播业务可以理解为终端尝试按照多播模式接收该多播业务，可能接收到该多播业务的业务数据，也可能无法接收到该多播业务的业务数据。
可选的，上述单播转多播请求可以为应用层数据。
本发明实施例接收网络设备针对多播业务发送的单播转多播请求，按照目标模式接收所述多播业务，所述目标模式包括单播模式和/或多播模式。这样，实现了NR系统中多播业务的传输。此外，由于通过单播转多播请求可以改变多播业务的传输模式，从而可以实现单播模式到多播模式的切换，因此，本发明实施例可以降低多播业务占用的资源，提高资源利用率。
可选的，在一实施例中，接收到网络设备针对多播业务发送的单播转多 播请求后，所述方法还包括：
根据所述多播业务的服务区域，确定所述目标模式。
本发明实施例中，可以基于所述终端是否位于所述多播业务的服务区域内，确定目标模式，并在确定目标模式后，按照目标模式接收所述多播业务。例如，一实施例中，在第一终端位于所述多播业务的服务区域内，则确定目标模式包括多播业务。进一步的，目标模式还可以包括单播模式。在另一实施例中，在第一终端位于所述多播业务的服务区域外时，确定目标模式包括单播业务。应理解，第一终端位于所述多播业务的服务区域内时，可以理解为确定第一终端位于所述多播业务的服务区域内的状态，例如可以理解为第一终端位于所述多播业务的服务区域内的情况下。
应理解，由于多播模式可能接收到多播业务的业务数据，也可能无法接收到多播业务的业务数据。在一可选实施例中，为了保证多播业务的正常接收，可以始终保持单播模式接收多播业务。换句话说，上述目标模式可以包括单播模式，或者目标模式包括多播模式和单播模式。
可选的，可以基于网络设备提供的多播业务信息。该多播业务信息可以为多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)业务列表，例如，网络设备可以通过广播或者专用信令的方式向接入该网络设备的终端提供MBMS业务列表。接入该网络设备的终端可以基于该MBMS业务列表确定该终端是否位于指定的多播业务的服务区域内。
需要说明的是，为了提高网络设备与第一终端理解的一致性，以更好的控制单播模式到多播模式转换的针对性，第一终端还可以按照以下各情况执行相应的终端行为，以下对此进行详细说明。
可选的，在一实施例中，第一终端基于单播转多播请求还可以向网络设备发送响应消息，以通知网络设备当前第一终端是否同意按照多播模式接收所述多播业务。例如，在一实施例中，所述方法还包括：
位于所述多播业务的服务区域内时，向所述网络设备发送第一响应消息，所述第一响应消息用于指示所述第一终端同意按照多播模式接收所述多播业务。
本实施例中，第一终端位于所述多播业务的服务区域内时，可以发送第 一响应消息，此时上述目标模式可以包括多播模式和单播模式。也就是说，第一终端位于所述多播业务的服务区域内时，所述第一终端按照单播模式和多播模式接收该多播业务。
可选的，第一响应消息用于指示所述第一终端同意按照多播模式接收所述多播业务，也可以理解为第一响应消息用于指示第一终端位于所述多播业务的服务区域内。
进一步的，当第一终端位于所述多播业务的服务区域外时，第一终端可以不发送响应消息，也可以发送第二响应消息。例如，本实施例中，所述方法还包括：
位于所述多播业务的服务区域外时，向所述网络设备发送第二响应消息，所述第二响应消息用于指示所述第一终端不同意按照多播模式接收所述多播业务。
本实施例中，上述第二响应消息用于指示所述第一终端不同意按照多播模式接收所述多播业务，也可以理解为第二响应消息用于指示所述第一终端位于所述多播业务的服务区域外。
可选的，在另一实施例中，所述方法还包括：
位于所述多播业务的服务区域内时，向所述网络设备发送第二响应消息，所述第二响应消息用于指示所述第一终端不同意按照多播模式接收所述多播业务。
在本发明实施例中，网络设备在向第一终端针对多播业务发送单播转多播请求之后还可以包括以下行为：
接收所述第一终端针对所述单播转多播请求发送的响应消息；
根据所述响应消息确定所述多播业务的传输模式；
按照所述传输模式发送所述多播业务，所述传输模式包括单播模式和/或多播模式。
需要说明的是，网络设备基于第一终端针对单播转多播请求发送的响应消息，可以确定同意按照多播模式接收所述多播业务的第一终端的数量值，并根据该数量值与第一预设值的大小关系，确定网络设备针对所述多播业务的传输模式。例如，所述数量值大于第一预设值时，确定所述传输模式包括 多播模式。该第一预设值可以由协议约定，也可以由网络设备自行决定，在此不做进一步的限定。
可选的，在另一可选实施例中，所述方法还包括：
位于所述多播业务的服务区域内时，针对所述多播业务向所述网络设备发送第二多播会话加入请求。
本实施例中，在确定所述第一终端位于所述多播业务服务区域内的情况下，第一终端可以针对所述多播业务向所述网络设备发送第二多播会话加入请求，以请求建立所述多播业务的多播模式数据通道。例如，第一终端在多播业务的服务区域，但是该多播业务的多播链路(即多播模式数据通道)还没有建立，则第一终端发起多播会话建立过程请求建立多播模式数据通道。本发明实施例中，由第一终端再次发送第二多播会话加入请求，以请求网络设备建立所述多播业务的多播模式数据通道，这样可以提高网络设备与第一终端理解的一致性，以提高网络设备对单播模式转多播模式控制的准确性。
应理解，第一终端按照多播模式接收多播业务具体可以包括以下步骤：
接收携带于小区系统消息中的目标信息，所述目标信息用于指示所述多播业务的多播模式对应的接收方法；
根据所述目标信息，以多播模式接收所述多播业务。
进一步的，在一实施例中，所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：
以多播模式接收到所述多播业务的业务数据时，向所述网络设备发送第一请求消息，所述第一请求消息用于请求去激活单播模式数据通道。
本发明实施例中，去激活单播模式数据通道可以理解为释放协议数据单元(Protocol Data Unit，PDU)会话或无线资源控制(Radio Resource Control，RRC)连接。由于以多播模式接收到所述多播业务的业务数据后，去激活单播模式数据通道，从而降低了该多播业务的资源占用。
可选的，在一实施例中，所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：
在预设时间段内，以多播模式未接收到所述多播业务的业务数据时，按 照单播模式接收所述多播业务。
本发明实施例中，第一终端可以维护一个定时器，如果在定时器运行期间内没有以多播方式接收到多播业务的业务数据，则第一终端可以保持采用单播模式接收多播业务。例如，第一终端在接收到单播转多播请求后，启动该定时器，当定时器超时，第一终端还没有以多播模式接收到多播业务的业务数据，则第一终端判断网络设备没有将多播业务从单播模式转到多播模式，则第一终端可以保持采用单播模式接收多播业务，并不在继续尝试以多播方式接收多播业务。
进一步的，在定时器超时前，第一终端以多播模式接收到多播业务的业务数据时，第一终端还可以请求去激活单播模式数据通道，以降低该多播业务的资源占用。换句话说，所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：
在预设时间段内，以多播模式接收到所述多播业务的业务数据时，向所述网络设备发送第二请求消息，所述第二请求消息用于去激活单播模式数据通道。
进一步的，在一可选实施例中，网络设备还可以直接通过指示信息指示第一终端的接收模式。例如，网络设备在确定多播业务的传输模式(单播模式和/或多播模式)后，向所述第一终端发送指示信息，所述指示信息用于指示位于所述多播业务的服务区域内的第一终端以多播模式或多播模式接收所述多播业务。
该指示信息可以指示位于多播业务内的第一终端按照多播模式或单播模式接收多播业务。此时，第一终端包括以下行为：
一实施例中，所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：
位于所述多播业务的服务区域内，且接收到所述网络设备发送的第一指示信息的情况下，按照多播模式接收所述多播业务；
向所述网络设备发送第三请求消息，所述第三请求消息用于去激活单播模式数据通道；
其中，所述第一指示信息用于指示基于多播模式接收所述多播业务。
本发明实施例中，由于在接收到第一指示信息后，去激活单播模式数据通道，从而可以降低多播模式的占用的资源。
另一实施例中，所述目标模式包括单播模式和多播模式的情况下，所述方法还包括：
位于所述多播业务的服务区域内，且接收到所述网络设备发送的第二指示信息时，按照单播模式接收所述多播业务，所述第二指示信息用于指示基于单播模式接收所述多播业务。
本发明实施例中，通过第二指示信息指示第一终端基于单播模式接收所述多播业务，从而使得第一终端无需再次尝试按照多播模式接收多播业务，从而可以保证第一终端与网络设备的理解一致，降低第一终端的电量损耗。
需要说明的是，对于位于多播业务服务区域外的第一终端可以理解为一直采用单播模式接收多播业务。进一步的，当位于多播业务服务区域外的第一终端切换至位于多播业务服务区域内时，也可以再次触发尝试以多播模式接收该多播业务。此外，本发明实施例中，可以是位于多播业务服务区域内的全部或者部分第一终端可以从单播模式切换到多播模式。
为了更好的理解本发明，以下结合图3对本发明的实现过程进行详细说明。如图3所示，包括以下步骤：
步骤301，通过单播方式向第一终端提供多播业务。比如接收多播业务1的用户数量较少，内容提供方(Content Provider)通过单播的方式给多个第一终端提供多播业务。
步骤302，第二终端发起多播会话建立请求。换句话说，第二终端对某多播业务感兴趣，则可以发起多播会话建立请求。比如，多播业务1正在通过单播方式提供，新用户终端(即第二终端)检测到其在该多播业务的服务区域内，发起多播会话建立过程请求加入多播会话。可选的，第二终端可以发送多播会话建立请求消息，该多播会话建立请求消息可以携带多播业务信息(例如Multicast IP或多播组标识(Temporary Mobile Group Identifier，TMGI))；第二终端也可以发送单播会话建立请求消息，该单播会话建立请求消息中携带多播业务信息表示多播会话建立请求，该单播会话建立请求消息可以理解为PDU会话建立请求消息(PDU Session Establishment Request)。
步骤303，内容提供方(即多播广播服务(Multicast Broadcast Service，MBS)内容提供方)决定将某多播业务从单播提供方式转换为多播提供方式。比如，通过统计正在接收或请求接收该多播业务的终端总数量来判断，如用户总数量超过预设阈值，则决定从单播提供方式转换为多播提供方式。
步骤304，内容提供方请求以正以单播方式接收多播业务的第一终端从单播接收模式转换到多播接收模式。该请求信息可以是通过应用层数据请求的。
步骤305，单播模式接收的第一终端检测是否在多播业务的服务区域。例如，第一终端通过检测其周围小区的系统消息判断小区是否提供该多播业务。如果小区系统信息指示其提供该多播业务，则第一终端确定其在该多播业务的服务区域内，否则不在该多播业务的服务区域内。
步骤306，可选的，如果单播模式接收的第一终端检测其在多播业务的服务区域内，则发起多播会话建立过程。比如，第一终端在多播业务的服务区域，但是该多播业务的多播链路还没有建立，则第一终端发起多播会话建立过程请求建立多播通道。
步骤307，可选的，如果第一终端检测其在多播业务的服务区域内，则响应模式切换请求。比如，第一终端在多播业务的服务区域内，并接收到了单播转换到多播的模式切换请求，则回复其同意将单播接收模式转换到多播接收模式，第一终端可以通过应用层(如IP报文)回复模式切换请求。
步骤308，内容提供方接收第一终端的模式切换响应，判断是否正式从单播转换到多播。比如基于接收到的模式切换响应总数量判断，如总数量超过预设阈值，则正式确定从单播转换到多播。
步骤309，第一终端通过单播方式接收多播业务数据，同时等待多播方式接收该多播业务数据。比如第一终端根据网络侧提供的多播接收方法接收在特定的时频位置(如能够提供多播业务的小区在系统消息中指示该多播业务的接收方法，第一终端通过读取小区的系统消息获悉如何接收数据)接收多播业务数据。
步骤310，通过多播模式接收到了多播业务数据，则释放协议数据单元会话或无线资源控制连接。如第一终端通过网络侧提供的多播业务接收方法在 特定的时频位置接收到了多播数据，则第一终端判定网络设备已经将该多播业务从单播提供方式转换为多播提供方式，则发起PDU会话释放过程请求释放单播链路。额外的，第一终端发起RRC连接释放过程请求进入空闲态，比如第一终端除该多播业务外没有其他单播业务需要接收，则请求释放RRC连接进入空闲态。
可选的，在一实施例中，第一终端还可以维护一个定时器，如果在定时器运行期间内没有以多播方式接收到多播数据，则第一终端仍保持在单播接收方式。比如，第一终端在发送模式转换响应请求后，启动一个定时器，当定时器超时，第一终端还没有以多播方式接收到多播数据，则第一终端判定网络设备没有将单播提供方式转换到多播提供方式，则第一终端继续保持在单播接收方式，不在尝试以多播方式接收多播数据。
可选的，在一实施例中，网络设备可以指示第一终端多播业务从单播模式转换为多播模式，第一终端发起PDU会话释放过程请求释放单播链路或发起RRC连接释放过程请求进入空闲态。比如，网络设备指示第一终端剩余多播业务正式从单播提供方式转换为多播提供方式，则第一终端可释放多播业务的单播链路，以多播方式接收该多播业务。
可选的，在一实施例中，网络设备指示第一终端多播业务继续以单播模式提供，则第一终端继续保持以单播方式接收。比如，网络设备指示第一终端剩余多播业务继续以单播模式提供，则第一终端继续保持以单播方式接收，不在尝试以多播方式接收，如不再检测多播资源位置。
