技术领域technical field

本公开涉及通信技术领域，具体涉及一种多播数据的处理方法、核心网网关、业务服务器及终端。The present disclosure relates to the field of communication technologies, and in particular, to a method for processing multicast data, a core network gateway, a service server and a terminal.

背景技术Background technique

为有效利用移动网络资源，提出了多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)，该业务是一种从一个数据源向多个目标移动终端传输数据的技术，实现了网络(包括核心网，传输网和接入网)资源的共享，提高了网络资源，尤其是空口资源利用率。In order to effectively utilize mobile network resources, the Multimedia Broadcast Multicast Service (MBMS) is proposed, which is a technology for transmitting data from one data source to multiple target mobile terminals, and realizes the , transmission network and access network) resource sharing, which improves the utilization rate of network resources, especially air interface resources.

4G中MBMS面向的场景主要是广播电视，公共安全等业务场景，故将业务本身预定义为多播业务，未了保证覆盖在网络中划分为多个多播广播区域，在这些区域进行广播，并将这些广播业务具体发送的位置和临时移动组标识(Temporary Mobile Group Identity，TMGI)告知终端，终端根据自己订阅的情况主动地去对应的位置获取响应的广播内容。具体地在空口上，支持两种传输方式，一种是多播广播单频网(Multicast Broadcast Single Frequency Network，MBSFN)，一种是单小区点对多点(Single Cell Point-To Multipoint,SC-PTM)，但无论空口采用哪种模式，所发送的内容都是预先定义的业务服务器产生的多播业务。In 4G, MBMS is mainly oriented to business scenarios such as radio and television, public security, etc. Therefore, the business itself is predefined as a multicast service, and the network is divided into multiple multicast broadcast areas without guaranteeing coverage, and broadcast in these areas. The specific location of these broadcast services and the Temporary Mobile Group Identity (TMGI) are notified to the terminal, and the terminal can actively go to the corresponding location to obtain the corresponding broadcast content according to its own subscription. Specifically, on the air interface, two transmission modes are supported, one is Multicast Broadcast Single Frequency Network (MBSFN), the other is Single Cell Point-To Multipoint (SC- PTM), but no matter which mode the air interface adopts, the content sent is the multicast service generated by the predefined service server.

MBSFN的主要原理是将预先定义的多播内容在MBSFN区域内的多个基站上同时传输，且在MBSFN子帧上传输，通过***信息块(System Information Blocks，SIB2)将MBSFN子帧情况告知终端，通过SIB13将MBSFN区域，多播控制信道(Multicast Control Channel，MCCH)配置和MBMS通知消息的配置信息告知终端，终端通过接收MCCH携带的MBSFN区域配置消息获取多播业务信道(Multicast Traffic Channel，MTCH)上携带的MBMS业务信息以及MTCH对应的物理广播信道(Physical Broadcast Channel，PBCH)发送的具***置，终端通过以上这些信息的广播，根据自己感兴趣的内容主动收听。The main principle of MBSFN is to transmit the predefined multicast content on multiple base stations in the MBSFN area at the same time, and transmit it on the MBSFN subframe, and inform the terminal about the MBSFN subframe through the System Information Blocks (SIB2). , notify the terminal of the MBSFN area, the Multicast Control Channel (MCCH) configuration and the configuration information of the MBMS notification message through SIB13, and the terminal obtains the Multicast Traffic Channel (Multicast Traffic Channel, MTCH by receiving the MBSFN area configuration message carried by the MCCH) ) carried on the MBMS service information and the specific location of the physical broadcast channel (Physical Broadcast Channel, PBCH) corresponding to the MTCH, the terminal actively listens according to the content of interest through the broadcast of the above information.

SC-PTM的主要原理是预先定义的多播内容在某个小区内广播或者多播，在SIB20上广播SC-MCCH物理下行控制信道(Physical Downlink Control Channel，PDCCH)的时域配置信息，终端通过解调SC-MCCH PDCCH获得MCCH里携带的SC-PTM配置消息获取SC-MTCH上携带的MBMS业务信息以及SC-MTCH PDCCH调度信息等，终端通过以上这些信息的广播，根据自己感兴趣的内容主动收听。The main principle of SC-PTM is that the predefined multicast content is broadcast or multicast in a certain cell, and the time domain configuration information of the SC-MCCH Physical Downlink Control Channel (PDCCH) is broadcast on SIB20. Demodulate the SC-MCCH PDCCH to obtain the SC-PTM configuration message carried in the MCCH to obtain the MBMS service information and SC-MTCH PDCCH scheduling information carried on the SC-MTCH. listen.

面向现在以及未来典型的多播组播场景，比如世界杯直播体育场多机位高清内容，演唱会明星后台现场追踪等业务，目前是单播业务，但由于该类业务普遍是在某个集中范围内大量用户获取观看，下行采用单播的方式将导致网络拥塞，可能所有用户均不能观看，下行通过多播的方式发送给申请观看的用户是非常有效的方法。For typical multicast and multicast scenarios now and in the future, such as multi-camera high-definition content of the World Cup live broadcast stadium, live tracking of concert stars in the background, etc., it is currently a unicast service, but because such services are generally within a certain concentration range A large number of users get to watch, and the downlink unicast method will cause network congestion, and all users may not be able to watch. It is a very effective method to send the downlink to users who apply for viewing.

上述通过单播方式申请内容，网络通过多播方式发送给终端的技术方式是一种动态的按需的MBMS业务，完全区别相关技术中的预定义的多播组播技术，是一种新的技术框架。由于终端采用单播的方式发起业务申请，按照相关技术，业务服务器也会采用单播的方式发送业务内容，即最终发送给终端的业务包的网际互连协议(Internet Protocol，IP)地址是终端的单播地址，由于对应数据包需要发送给多个用户，使用终端的单播地址无法实现多播广播的需求，终端收到该数据包发现跟自己的IP地址不匹配，将丢弃该数据包。The above-mentioned technical method in which the content is applied for through unicast and the network sends to the terminal through multicast is a dynamic on-demand MBMS service, which is completely different from the predefined multicast multicast technology in the related art, and is a new kind of service. technical framework. Since the terminal uses unicast to initiate a service application, according to related technologies, the service server also uses unicast to send service content, that is, the Internet Protocol (IP) address of the service package finally sent to the terminal is the terminal Since the corresponding data packet needs to be sent to multiple users, the use of the terminal's unicast address cannot achieve the requirement of multicast broadcasting. The terminal receives the data packet and finds that it does not match its own IP address, and will discard the data packet. .

具体实施方式detailed description

为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure more clear, detailed description will be given below with reference to the accompanying drawings and specific embodiments.

如图1所示，本公开实施例提供一种多播数据的处理方法，应用于核心网网关，包括：As shown in FIG. 1 , an embodiment of the present disclosure provides a method for processing multicast data, which is applied to a core network gateway, including:

步骤11，接收业务服务器发送的第一数据包； Step 11, receiving the first data packet sent by the service server;

步骤12，对所述第一数据包进行处理，得到第二数据包；所述第二数据包携带的数据与所述第一数据包携带的数据相同，所述第二数据包的包头包含终端的多播IP地址和业务服务器的源IP地址。Step 12: Process the first data packet to obtain a second data packet; the data carried by the second data packet is the same as the data carried by the first data packet, and the header of the second data packet contains the terminal The multicast IP address and the source IP address of the service server.

本步骤中，由核心网网关将第一数据包的包头转换为终端的多播IP地址和业务服务器的源IP地址。其中，终端的多播IP地址由核心网网元为终端配置。In this step, the core network gateway converts the packet header of the first data packet into the multicast IP address of the terminal and the source IP address of the service server. The multicast IP address of the terminal is configured for the terminal by the core network element.

步骤13，向终端发送所述第二数据包。Step 13: Send the second data packet to the terminal.

本步骤中，第二数据包的发送既可以通过点对点方式也可以通过点对多点方式，核心网网关可以根据申请该业务用户的数量在点到点和点到多点模式间动态转换。In this step, the second data packet can be sent either in a point-to-point manner or in a point-to-multipoint manner, and the core network gateway can dynamically switch between point-to-point and point-to-multipoint modes according to the number of users applying for the service.

其中，业务服务器包括但不限于内容提供商、应用功能等。The service server includes, but is not limited to, content providers, application functions, and the like.

由于第二数据包的包头包含终端的多播IP地址，即终端虽然通过单播方式申请内容，但是核心网网关将其发送的数据包的包头转换为多播IP地址，使得额终端能够识别多播数据包，可以解决相关技术中终端无法识别多播数据包导致多播数据包被丢弃的问题。Because the header of the second data packet contains the multicast IP address of the terminal, that is, although the terminal applies for content through unicast, the core network gateway converts the header of the data packet sent by it into a multicast IP address, so that the terminal can identify multiple It can solve the problem that the terminal cannot identify the multicast data packet and the multicast data packet is discarded in the related art.

作为一个可选实施例，所述第一数据包包含：外层包头以及内层包头；所述内层包头包含终端的多播IP地址和业务服务器的源IP地址；As an optional embodiment, the first data packet includes: an outer header and an inner header; the inner header includes the multicast IP address of the terminal and the source IP address of the service server;

相应的，步骤12包括：Correspondingly, step 12 includes:

该实施例中，业务服务器采用单播IP地址嵌套多播IP地址的方式向核心网网关发送数据包，由核心网网关将其接收到的数据包的外层包头丢弃，从而得到第二数据包。In this embodiment, the service server sends a data packet to the core network gateway by using a unicast IP address nested with a multicast IP address, and the core network gateway discards the outer header of the received data packet, thereby obtaining the second data Bag.

业务服务器按照源IP地址+多播IP地址的方式封装数据包，为了复用业务服务器和核心网网关之间已有的单播隧道，业务服务器在该数据包的外层封装终端的单播IP地址，并将第一数据包发送给核心网网关。外层的单播IP地址的封装方式有如下两种实施方式：The service server encapsulates the data packet according to the source IP address + multicast IP address. In order to reuse the existing unicast tunnel between the service server and the core network gateway, the service server encapsulates the unicast IP of the terminal in the outer layer of the data packet. address, and send the first data packet to the core network gateway. There are two ways to encapsulate the outer unicast IP address:

方式一：如果终端的单播IP地址采用互联网协议第6版(Internet Protocol Version 6，IPV6)，外层包头可以直接封装终端的单播IP地址；Method 1: If the unicast IP address of the terminal adopts Internet Protocol Version 6 (IPV6), the outer header can directly encapsulate the unicast IP address of the terminal;

方式二：如果终端的单播IP地址采用IPV4，该地址为核心网分配的网内IP地址，由于上行数据包核心网网关进行了地址转换(Network Address Translation，NAT)，将内部地址转换为核心网网关外部地址和端口号(用户唯一的)，外层封装的终端单播IP为可以识别终端的网关地址。Method 2: If the unicast IP address of the terminal adopts IPV4, the address is the intra-network IP address assigned by the core network. Because the core network gateway of the uplink data packet performs address translation (Network Address Translation, NAT), the internal address is converted into the core network. The external address and port number of the network gateway (unique to the user), and the terminal unicast IP encapsulated in the outer layer is the gateway address that can identify the terminal.

作为另一个可选实施例，所述第一数据包的包头包含终端的单播IP地址和业务服务器的源IP地址；As another optional embodiment, the header of the first data packet includes the unicast IP address of the terminal and the source IP address of the service server;

相应的，步骤12包括：Correspondingly, step 12 includes:

该实施例中，核心网网关采用移动网内单播IP地址转多播IP地址的方式形成第二数据包。即业务服务器按照源IP地址+单播IP地址的方式封装第一数据包，与已有单播数据封装和发送方式一致，业务服务器和核心网网关间发送多个数据。In this embodiment, the core network gateway forms the second data packet by converting the unicast IP address to the multicast IP address in the mobile network. That is, the service server encapsulates the first data packet according to the source IP address + unicast IP address, which is consistent with the existing unicast data encapsulation and transmission method, and multiple data are sent between the service server and the core network gateway.

终端的单播IP地址的封装方式有如下两种实施方式：There are two ways to encapsulate the unicast IP address of the terminal:

方式一：如果终端的单播IP地址采用IPV6，外层包头可以直接封装终端的单播IP地址；Method 1: If the unicast IP address of the terminal adopts IPV6, the outer packet header can directly encapsulate the unicast IP address of the terminal;

方式二：如果终端的单播IP地址采用IPV4，该地址为核心网分配的网内IP地址，由于上行数据包核心网网关进行了地址转换(NAT)，将内部地址转换为核心网网关外部地址和端口号(用户唯一的)，外层封装的终端单播IP为可以识别终端的网关地址。Method 2: If the unicast IP address of the terminal adopts IPV4, the address is the intra-network IP address assigned by the core network. Because the core network gateway of the uplink data packet performs address translation (NAT), the internal address is converted to the external address of the core network gateway. and port number (unique to the user), the terminal unicast IP encapsulated in the outer layer is the gateway address that can identify the terminal.

核心网网关识别多播业务，将终端的单播IP地址替换为多播IP地址，得到第二数据包，并将第二数据包发送给终端。The core network gateway identifies the multicast service, replaces the unicast IP address of the terminal with the multicast IP address, obtains a second data packet, and sends the second data packet to the terminal.

由于业务服务器使用的是单播协议封装的数据，为了让终端的通信层能够和应用层互相理解，不会导致数据包的丢失，终端通信层收到数据包后将多播地址更换为单播IP地址递交给应用层。通过该方法，终端使用传统的单播的流程可以接收多播的数据。Since the service server uses the data encapsulated by the unicast protocol, in order to allow the communication layer of the terminal and the application layer to understand each other and not cause the loss of data packets, the communication layer of the terminal changes the multicast address to unicast after receiving the data packet. The IP address is passed to the application layer. Through this method, the terminal can receive the multicast data by using the traditional unicast process.

本公开实施例中，步骤12之前，所述方法还包括：In this embodiment of the present disclosure, before step 12, the method further includes:

IP五元组信息；IP quintuple information;

多播IP地址；multicast IP address;

IP流到QoS流映射配置。IP flow to QoS flow mapping configuration.

例如，业务服务器向核心网控制面网元(比如策略控制网元、会话管理网元等)通过控制面提供业务和用户的关联信息以及可选地协商核心网网关的接收地址。即通知核心网网关哪个业务是多播业务，以及哪个用户在申请该业务。核心网控制面网元根据业务服务器提供的信息，为每个接收终端的服务质量QoS流设置可以识别是多播同一内容的业务过滤规则，例如核心网网关的接收地址、IP五元组信息以及多播IP地址中的至少一项。For example, the service server provides service and user association information to the core network control plane network elements (such as policy control network elements, session management network elements, etc.) through the control plane, and optionally negotiates the receiving address of the core network gateway. That is, the core network gateway is notified which service is the multicast service and which user is applying for the service. Based on the information provided by the service server, the core network control plane network element sets service filtering rules for the QoS flow of each receiving terminal that can identify the same content as multicast, such as the receiving address of the core network gateway, IP quintuple information, and At least one of the multicast IP addresses.

综上，本公开实施例针对通过单播方式申请内容，网络通过多播方式发送给终端的动态按需多播场景，提出了多播业务识别以及数据处理的方法，从而使得终端能够识别多播数据包，可以解决相关技术中终端无法识别多播数据包导致多播数据包被丢弃的问题。To sum up, the embodiments of the present disclosure propose a method for multicast service identification and data processing for the dynamic on-demand multicast scenario in which the content is applied for through unicast and the network sends it to the terminal through multicast, so that the terminal can identify the multicast service. The data packet can solve the problem in the related art that the terminal cannot identify the multicast data packet and the multicast data packet is discarded.

如图2所示，本公开实施例还提供一种多播数据的处理方法，应用于业务服务器，包括：As shown in FIG. 2 , an embodiment of the present disclosure further provides a method for processing multicast data, applied to a service server, including:

步骤21，接收终端采用单播的方式发送的业务请求；Step 21, receiving a service request sent by the terminal in a unicast manner;

步骤22，根据所述业务请求，向核心网网关发送第一数据包；其中，所述第一数据包对应的业务为多播业务。Step 22: Send a first data packet to the core network gateway according to the service request; wherein, the service corresponding to the first data packet is a multicast service.

作为一个可选实施例，所述第一数据包包含：外层包头以及内层包头；As an optional embodiment, the first data packet includes: an outer layer header and an inner layer header;

所述外层包头包含终端的单播IP地址；或者，所述外层包头为核心网网关的IP地址。由核心网网关丢弃所述第一数据包的外层包头，得到所述第二数据包。The outer-layer packet header includes the unicast IP address of the terminal; or, the outer-layer packet header is the IP address of the core network gateway. The core network gateway discards the outer header of the first data packet to obtain the second data packet.

作为另一个可选实施例，所述第一数据包的包头包含终端的单播IP地址和业务服务器的源IP地址。由核心网网关将所述第一数据包的包头的单播IP地址修改为多播IP地址，得到所述第二数据包。As another optional embodiment, the header of the first data packet includes the unicast IP address of the terminal and the source IP address of the service server. The core network gateway modifies the unicast IP address of the header of the first data packet to a multicast IP address to obtain the second data packet.

即业务服务器按照源IP地址+单播IP地址的方式封装第一数据包，与已有单播数据封装和发送方式一致，业务服务器和核心网网关间发送多个数据。That is, the service server encapsulates the first data packet according to the source IP address + unicast IP address, which is consistent with the existing unicast data encapsulation and transmission method, and multiple data are sent between the service server and the core network gateway.

方式二：如果终端的单播IP地址采用IPV4，该地址为核心网分配的网内IP地址，由于上行数据包核心网网关进行了地址转换(NAT)，将内部地址转换为核心网网关外部地址和端口号(用户唯一的)，外层封装的终端单播 IP为可以识别终端的网关地址。Method 2: If the unicast IP address of the terminal adopts IPV4, the address is the intra-network IP address assigned by the core network. Because the core network gateway of the uplink data packet performs address translation (NAT), the internal address is converted to the external address of the core network gateway. and port number (unique to the user), the terminal unicast IP encapsulated in the outer layer is the gateway address that can identify the terminal.

本公开实施例中，所述方法还包括：In the embodiment of the present disclosure, the method further includes:

IP五元组信息；IP quintuple information;

多播IP地址；multicast IP address;

IP流到QoS流映射配置。IP flow to QoS flow mapping configuration.

综上，本公开实施例针对通过单播方式申请内容，网络通过多播方式发送给终端的动态按需多播场景，提出了多播业务识别以及数据处理的方法，从而使得终端能够识别多播数据包，可以解决相关技术中终端无法识别多播数据包导致多播数据包被丢弃的问题。To sum up, the embodiments of the present disclosure propose a multicast service identification and data processing method for the dynamic on-demand multicast scenario in which content is applied for through unicast and the network sends it to the terminal through multicast, so that the terminal can identify the multicast service. The data packet can solve the problem in the related art that the terminal cannot identify the multicast data packet and the multicast data packet is discarded.

如图3所示，本公开实施例还提供一种多播数据的处理方法，应用于终端，包括：As shown in FIG. 3 , an embodiment of the present disclosure further provides a method for processing multicast data, applied to a terminal, including:

步骤31，向业务服务器发送业务请求； Step 31, sending a service request to the service server;

步骤32，接收核心网网关发送的第二数据包，其中，所述第二数据包由所述核心网网关对业务服务器发送的第一数据进行处理得到；Step 32: Receive the second data packet sent by the core network gateway, wherein the second data packet is obtained by processing the first data sent by the service server by the core network gateway;

本公开实施例中，由核心网网关将业务服务器生成的第一数据包的包头转换为终端的多播IP地址和业务服务器的源IP地址。其中，终端的多播IP地址由核心网网元为终端配置。In the embodiment of the present disclosure, the core network gateway converts the packet header of the first data packet generated by the service server into the multicast IP address of the terminal and the source IP address of the service server. The multicast IP address of the terminal is configured for the terminal by the core network element.

其中，第二数据包的发送既可以通过点对点方式也可以通过点对多点方式，核心网网关可以根据申请该业务用户的数量在点到点和点到多点模式间动态转换。The second data packet can be sent either in a point-to-point manner or a point-to-multipoint manner, and the core network gateway can dynamically switch between point-to-point and point-to-multipoint modes according to the number of users applying for the service.

其中，所述外层包头包含终端的单播IP地址；或者，所述外层包头为核心网网关的IP地址Wherein, the outer packet header contains the unicast IP address of the terminal; or, the outer packet header is the IP address of the core network gateway

本公开实施例由核心网网关识别多播业务，将终端的单播IP地址替换为多播IP地址，得到第二数据包，并将第二数据包发送给终端。In the embodiment of the present disclosure, the core network gateway identifies the multicast service, replaces the unicast IP address of the terminal with the multicast IP address, obtains a second data packet, and sends the second data packet to the terminal.

由于业务服务器使用的是单播协议封装的数据，为了让终端的通信层能够和应用层互相理解，不会导致数据包的丢失，终端通信层收到数据包后将多播地址更换为单播IP地址递交给应用层。通过该方法，终端使用传统的单播的流程可以接收多播的数据。即步骤32包括：Since the service server uses the data encapsulated by the unicast protocol, in order to allow the communication layer of the terminal and the application layer to understand each other and not cause the loss of data packets, the communication layer of the terminal changes the multicast address to unicast after receiving the data packet. The IP address is passed to the application layer. Through this method, the terminal can receive the multicast data by using the traditional unicast process. That is, step 32 includes:

所述终端的接入层将所述第二数据包的包头的多播IP地址修改为单播IP 地址得到第三数据包，并将第三数据包传输给终端的应用层或非接入层。The access layer of the terminal modifies the multicast IP address of the packet header of the second data packet to a unicast IP address to obtain a third data packet, and transmits the third data packet to the application layer or non-access layer of the terminal .

为了更清楚的说明本公开实施例提供的多播数据的处理方法，下面结合附图及示例进行描述。In order to more clearly illustrate the multicast data processing method provided by the embodiments of the present disclosure, the following description is made with reference to the accompanying drawings and examples.

示例一，如图4所示，单播地址嵌套多播地址方案Example 1, as shown in Figure 4, the unicast address nested multicast address scheme

步骤0，核心网网元或者业务服务器给终端配置多播IP地址。Step 0: The core network element or the service server configures a multicast IP address for the terminal.

步骤1，服务器向核心网控制面网元通过控制面提供业务和用户的关联信息以及可选地协商核心网网关(例如：用户面功能实体(User Plane Function，UPF)或网关(GateWay，GW))的接收地址。该步骤目的主要通知核心网网元哪个业务是多播业务，以及哪个用户在申请该业务。Step 1, the server provides the core network control plane network element with the associated information of the service and the user through the control plane, and optionally negotiates the core network gateway (for example: User Plane Function (UPF) or gateway (GateWay, GW) ) of the receiving address. The purpose of this step is mainly to inform the core network element which service is the multicast service and which user is applying for the service.

步骤2，核心网控制面网元根据业务服务器提供的信息，为每个接收终端的QoS流设置可以识别是多播广播同一内容的过滤规则：UPF接收地址(可选)+IP五元组信息。Step 2: According to the information provided by the service server, the network element of the core network control plane sets a filtering rule that can identify the same content as a multicast broadcast for the QoS flow of each receiving terminal: UPF receiving address (optional) + IP quintuple information .

步骤3，业务服务器按照源地址+多播地址的方式封装数据包，为了复用已有的服务器和核心网网关间的单播隧道，外层封装终端的单播相关的IP地址，并将数据发送给核心网网关。Step 3, the service server encapsulates the data packet according to the source address + multicast address. In order to reuse the unicast tunnel between the existing server and the core network gateway, the outer layer encapsulates the unicast related IP address of the terminal, and sends the data to the packet. Sent to the core network gateway.

外层终端单播相关IP地址的封装方式有如下两种方式：There are two ways to encapsulate the unicast-related IP address of the outer terminal:

方式1：如果终端的单播IP地址采用IPV6，外层可以直接封装终端定的单播IP地址。Mode 1: If the unicast IP address of the terminal adopts IPV6, the outer layer can directly encapsulate the unicast IP address set by the terminal.

方式2：如果终端的单播IP地址采用IPV4，该地址为核心网分配的网内IP地址，由于上行数据包核心网网关进行了地址转换(NAT)，将内部地址转换成UPF外部地址和端口号(用户唯一的)，外层封装的终端单播IP为可以识别终端的UPF地址。Mode 2: If the unicast IP address of the terminal adopts IPV4, the address is the intra-network IP address assigned by the core network. Because the core network gateway of the uplink data packet performs address translation (NAT), the internal address is converted into the UPF external address and port. The unicast IP of the terminal encapsulated in the outer layer is the UPF address that can identify the terminal.

步骤4，核心网网关根据业务过滤规则识别多播组播业务，将外层IP头去掉，并将数据发送给终端，数据发送既可以通过点对点方式也可以通过点对多点方式，基站可以根据申请该业务用户的数量在点到点和点到多点模式间动态转换。Step 4, the core network gateway identifies the multicast multicast service according to the service filtering rules, removes the outer IP header, and sends the data to the terminal. The number of users applying for this service is dynamically switched between point-to-point and point-to-multipoint modes.

步骤5，终端通信层收到数据包后将数据包发送给应用层。Step 5: After receiving the data packet, the terminal communication layer sends the data packet to the application layer.

步骤1，业务服务器向核心网控制面网元通过控制面提供业务和用户的关联信息以及可选地协商核心网网关(UPF/GW)的接收地址。该步骤目的主要通知核心网网元哪个业务是多播业务，以及哪个用户在申请该业务。Step 1, the service server provides the service and user association information to the core network control plane network element through the control plane, and optionally negotiates the receiving address of the core network gateway (UPF/GW). The purpose of this step is mainly to inform the core network element which service is the multicast service and which user is applying for the service.

步骤2，核心网控制面网元根据服务器提供的信息，为每个接收终端的QoS流设置可以识别是多播广播同一内容的过滤规则：UPF接收地址(可选)+IP五元组信息。Step 2: According to the information provided by the server, the network element of the core network control plane sets a filtering rule for the QoS flow of each receiving terminal that can identify the same content as a multicast broadcast: UPF receiving address (optional) + IP quintuple information.

步骤3，业务服务器按照源地址+终端单播地址的方式封装数据包，与已有单播数据封装和发送方式一致，业务服务器和核心网网关间发送多个数据。Step 3, the service server encapsulates the data packet according to the source address + terminal unicast address, which is consistent with the existing unicast data encapsulation and transmission method, and sends a plurality of data between the service server and the core network gateway.

终端单播相关IP地址的封装方式有如下两种方式：There are two ways to encapsulate the unicast-related IP address of the terminal:

步骤4，核心网网关根据业务过滤规则识别多播组播业务，将终端的单播IP地址替换为多播IP地址，并将数据发送给终端，数据发送既可以通过点对点方式也可以通过点对多点方式，基站可以根据申请该业务用户的数量在点到点和点到多点模式间动态转换。Step 4, the core network gateway identifies the multicast multicast service according to the service filtering rules, replaces the unicast IP address of the terminal with the multicast IP address, and sends the data to the terminal, and the data can be sent either in a point-to-point manner or in a point-to-point manner. In the multipoint mode, the base station can dynamically switch between point-to-point and point-to-multipoint modes according to the number of users applying for the service.

示例三，如图6所示，直接多播方案Example 3, as shown in Figure 6, direct multicast scheme

步骤1，服务器向核心网控制面网元通过控制面提供业务和用户的关联信息以及可选地协商核心网网关(UPF/GW)的接收地址。该步骤目的主要通知核心网网元哪个业务是多播业务，以及哪个用户在申请该业务。Step 1, the server provides the core network control plane network element with service and user association information through the control plane, and optionally negotiates the receiving address of the core network gateway (UPF/GW). The purpose of this step is mainly to inform the core network element which service is the multicast service and which user is applying for the service.

步骤2，核心网控制面网元根据服务器提供的信息，为每个接收终端的QoS流设置可以识别是多播广播同一内容的过滤规则：IP多播地址。Step 2: According to the information provided by the server, the network element of the core network control plane sets a filtering rule that can identify the same content as a multicast broadcast for the QoS flow of each receiving terminal: an IP multicast address.

步骤3，业务服务器按照源地址+多播地址的方式封装数据包，数据包根据多播协议发送，业务服务器和核心网网关间针对多个终端的相同数据仅发送一份。可选地，外层封装UPF地址，应用与业务服务器与核心网网关间不支持多播广播路由。In step 3, the service server encapsulates the data packet according to the source address + multicast address, the data packet is sent according to the multicast protocol, and only one copy of the same data for multiple terminals is sent between the service server and the core network gateway.
