Abstract
Description
Translated fromChinese技术领域technical field
本申请属于通信技术领域，具体涉及一种切换多播业务的方法及设备。The present application belongs to the technical field of communication, and in particular relates to a method and equipment for switching multicast services.
背景技术Background technique
终端在接收多播业务数据时，如果终端从源基站到目标基站的移动，源基站可以转发多播业务数据给目标基站，由目标基站判断源基站多播业务数据是否需要继续转发给终端。When the terminal receives multicast service data, if the terminal moves from the source base station to the target base station, the source base station can forward the multicast service data to the target base station, and the target base station determines whether the multicast service data of the source base station needs to be forwarded to the terminal.
在目标基站判断无需再转发时，无法通知源基站结束转发，只能是源基站在转发一段时间后自行结束转发。这样导致终端从源基站到目标基站的移动时多播业务数据可能会被丢失。When the target base station judges that no more forwarding is needed, the source base station cannot be notified to end the forwarding, and the source base station can only end the forwarding by itself after a period of forwarding. In this way, the multicast service data may be lost when the terminal moves from the source base station to the target base station.

上述多播数据中可以携带业务的相关信息，比如每个业务流或临时组对应一个序列号。The above multicast data may carry service-related information, for example, each service flow or temporary group corresponds to a sequence number.
步骤402：Source gNB向多播广播网络功能发送切换通知消息；Step 402: Source gNB sends a handover notification message to the multicast broadcast network function;
示例性地，Source gNB向AMF或SMF发送切换通知消息，比如MB NF为SMF时，通过AMF发送给SMF，MB NF为AMF时，直接发给AMF。Exemplarily, the Source gNB sends the handover notification message to the AMF or the SMF, for example, when the MB NF is the SMF, it sends it to the SMF through the AMF, and when the MB NF is the AMF, it sends it directly to the AMF.
可选地，切换通知消息(比如切换请求(Handover Required)消息)携带要切换的业务标识，比如QoS流标识(QoS Flow Identifier，QFI)或临时移动群组标识(TemporaryMobile Group Identity，TMGI)或协议数据单元会话标识(PDU Session ID)，进一步地，该切换通知消息还可以携带多播业务的相关信息，比如序列号(Serial Number，SN)。Optionally, the handover notification message (such as a handover request (Handover Required) message) carries the service identifier to be handed over, such as a QoS Flow Identifier (QoS Flow Identifier, QFI) or a Temporary Mobile Group Identity (TemporaryMobile Group Identity, TMGI) or protocol A data unit session identifier (PDU Session ID). Further, the handover notification message may also carry information related to the multicast service, such as a serial number (Serial Number, SN).
步骤403：MB NF向目标基站(Target gNB)发送切换请求(Handover Request)消息；Step 403: MB NF sends a handover request (Handover Request) message to the target base station (Target gNB);
其中，切换请求消息可以携带多播业务相关标识，比如TMGI和/或MB NF的标识；进一步地，该切换请求消息还可以可携带是否需要转发的指示。Wherein, the handover request message may carry multicast service-related identifiers, such as TMGI and/or MBNF identifiers; further, the handover request message may also carry an indication of whether forwarding is required.

步骤409：UE接入到目标基站，向目标基站发送切换完成(Handover Confirm)消息。Step 409: The UE accesses the target base station, and sends a Handover Confirm message to the target base station.
步骤410：目标基站向MB NF发送会话更新消息；Step 410: The target base station sends a session update message to the MB NF;
需要说明的是，如果步骤405中没有发送多播下行隧道信息，则此步骤发送。It should be noted that if the multicast downlink tunnel information is not sent in step 405, then this step sends it.
步骤411：MB NF通过多播下行隧道向目标基站发送接收到的多播业务数据。Step 411: The MB NF sends the received multicast service data to the target base station through the multicast downlink tunnel.
比如UPF在将缓存数据全部通过转发资源发送完毕后，向转发隧道发送结束报文，目标基站接收到结束报文后释放转发资源，停止发送接收到的转发数据。For example, after the UPF sends all the buffered data through the forwarding resources, it sends an end message to the forwarding tunnel. After receiving the end message, the target base station releases the forwarding resources and stops sending the received forwarding data.
