本申请涉及但不限于通信技术领域。This application relates to, but is not limited to, the field of communication technology.

背景技术Background technique

车联网(Vehicle to Everything，简称为：V2X)是指通过装载在车辆上的传感器、车载终端及电子标签提供车辆信息，图1为相关技术中一种通过网络信息平台向车辆发送信息的应用场景示意图，如图1所示，采用各种通信技术实现车与车(Vehicle to Vehicle，简称为：V2V)、车与人(Vehicle to Pedestrian，简称为：V2P)、车与路(路表示为基础设施)(Vehicle to Infrastructure，简称为：V2I)互连互通，并在信息网络平台上对信息进行提取、共享等有效利用，对车辆进行有效的管控和提供综合服务。在实际应用中，V2X还包括：路边通信单元(Road Side Unit，简称为：RSU)可以接收车辆请求，保证车辆接入互联网(Internet)，有网关的功能；此外，V2X还具有数据运算、存储、转发的功能。Vehicle to Everything (V2X) refers to providing vehicle information through sensors, vehicle terminals and electronic tags mounted on the vehicle. FIG. 1 is an application scenario of transmitting information to a vehicle through a network information platform in the related art. Schematic diagram, as shown in Figure 1, using various communication technologies to achieve Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P), Vehicle and Road (road representation) (Vehicle to Infrastructure, referred to as: V2I) interconnection and interoperability, and effective use of information extraction and sharing on the information network platform to effectively control and provide comprehensive services for vehicles. In practical applications, the V2X also includes: a Road Side Unit (RSU) that can receive vehicle requests, ensure that the vehicle accesses the Internet (Internet), and has a gateway function; in addition, the V2X also has data operations, Store and forward functions.

相关技术中V2X的实现主要包括两种方式：一种是，采用专用短距离通信(Dedicated Short Range Communication，简称为：DSRC)技术，另一种是，采用长期演进(Long-Term Evolution，简称为：LTE)技术；其中，DSRC基于电气和电子工程师协会(Institute of Electrical and Electronics Engineers，简称为：IEEE)定义的IEEE802.11P和IEEE1609系列标准，802.11P负责物理层和媒体接入控制(Medium Access Control，简称为：MAC)技术，1609负责上层规范，而基于LTE的V2X技术刚开始讨论，还没有标准。The implementation of V2X in the related art mainly includes two methods: one is to use Dedicated Short Range Communication (DSRC) technology, and the other is to use Long-Term Evolution (Long-Term Evolution, referred to as : LTE) technology; among them, DSRC is based on IEEE802.11P and IEEE1609 series standards defined by Institute of Electrical and Electronics Engineers (IEEE), 802.11P is responsible for physical layer and media access control (Medium Access Control, referred to as: MAC) technology, 1609 is responsible for the upper specification, and LTE-based V2X technology has just begun to discuss, there is no standard.

相关技术中的第三代合作伙伴计划(3rd Generation Partnership Project，简称为：3GPP)正在讨论的LTE V2X技术包括：路侧单元(Road Side Unit，简称为：RSU)可通过静止的用户设备(User Equipment，简称为UE)或演进型基站(Evolution Node B，简称为：eNB)实现，V2V/V2I/V2P可能通过PC5接口或Uu接口实现，其中，PC5接口是指设备到设备(Device to Device，简称为：D2D)的空中接口，Uu接口是指UE到eNB的空中接口。 The LTE V2X technology being discussed by the 3rd Generation Partnership Project (3GPP) in the related art includes: a Road Side Unit (RSU) that can pass a stationary user equipment (User Equipment, referred to as UE) or evolved base station (Evolution Node B, eNB for short), V2V/V2I/V2P may be implemented through a PC5 interface or a Uu interface, where the PC5 interface refers to a device to device (Device to Device, Referred to as: D2D) air interface, Uu interface refers to the air interface of the UE to the eNB.

为了有效地利用移动网络资源，3GPP中提出了多媒体广播多播业务(Multimedia Broadcast Multicast Service，简称为：MBMS)，该MBMS业务是一种从一个数据源向多个目标移动终端传送数据的技术，实现了网络(包括核心网和接入网)资源的共享，提高了网络资源(尤其是空中接口资源)的利用率。3GPP在R13的长期演进技术升级版(LTE-Advanced，简称为：LTE-A)中提出了单小区MBMS的研究课题，其中单小区MBMS业务在物理下行共享信道(Physical Downlink Shared Channel，简称为：PDSCH)上传输。In order to effectively utilize mobile network resources, a Multimedia Broadcast Multicast Service (MBMS) is proposed in the 3GPP, and the MBMS service is a technology for transmitting data from one data source to a plurality of target mobile terminals. The sharing of resources of the network (including the core network and the access network) is realized, and the utilization of network resources (especially air interface resources) is improved. 3GPP proposes a research topic of single-cell MBMS in R13's LTE-Advanced (LTE-A), where the single-cell MBMS service is in the physical downlink shared channel (Physical Downlink Shared Channel, referred to as: Transmission on PDSCH).

在相关技术中，eNB/路边单元RSU采用MBMS方式广播V2X业务，eNB接收到来自车载单元(On board Unit，简称为：OBU)的V2X业务数据后，经过核心网网元，该核心网网元例如为：分组数据网络网关(Packet Data Network Gateway，简称为：P-GW)和服务网关(Serving-Gateway，简称为：G-GW)等，发送到车联网应用服务器(V2X Application Server，简称为：V2X AS)；V2X AS再经过核心网网元发送到eNB，该核心网网元例如为：广播组播业务中心(Broadcast Multicast Service Center，简称为：BM-SC)、MBMS GW。上述描述的相关技术中的V2X中的数据传输方式，大量的V2X业务数据会经过的核心网迂回，导致eNB广播发送V2X业务数据时延过大。In the related art, the eNB/Roadside unit RSU broadcasts the V2X service in the MBMS mode, and after receiving the V2X service data from the On Board Unit (OBU), the eNB passes through the core network element, and the core network For example, the packet data network gateway (Packet Data Network Gateway, P-GW for short) and the service gateway (Serving-Gateway, G-GW for short) are sent to the application server (V2X Application Server). The V2X AS is transmitted to the eNB through the core network element. The core network element is, for example, a Broadcast Multicast Service Center (BM-SC) or an MBMS GW. In the data transmission mode in the V2X in the related art described above, a large amount of V2X service data will be bypassed by the core network, and the delay of the eNB broadcasting and transmitting the V2X service data is too large.

方法实施例Method embodiment

如图2所示，为本发明实施例提供的一种车联网业务数据包传输方法的流程图。本实施例提供的车联网业务数据包传输方法可以包括如下步骤，即步骤110～步骤130：FIG. 2 is a flowchart of a method for transmitting a data packet of a vehicle networking service according to an embodiment of the present invention. The method for transmitting the data packet of the car network service provided in this embodiment may include the following steps, that is, steps 110 to 130:

步骤110，应用层网元设备接收源基站发送的待传输的V2X业务数据包，其中，该应用层网元设备设置在核心网之外；Step 110: The application layer network element device receives the V2X service data packet to be transmitted sent by the source base station, where the application layer network element device is set outside the core network.

步骤120，应用层网元设备确定与V2X业务数据包所属的V2X业务类型对应的MBMS承载，其中，该MBMS承载预先建立在应用层网元设备与目标基站之间；Step 120: The application layer network element device determines an MBMS bearer corresponding to the V2X service type to which the V2X service data packet belongs, where the MBMS bearer is pre-established between the application layer network element device and the target base station;

步骤130，应用层网元设备在所确定的MBMS承载上将V2X业务数据包发送给目标基站。Step 130: The application layer network element device sends the V2X service data packet to the target base station on the determined MBMS bearer.

通过本发明实施例，通过设置在核心网之外的应用层网元设备，在与V2X业务数据包所属的V2X业务类型对应的MBMS承载上，将V2X业务数据包发送给目标基站，解决了相关技术中，大量的V2X业务数据会经过的核心网迂回，导致eNB广播发送V2X业务数据时延过大的问题，实现了V2X业务数据不需要经过核心网网元和V2X AS而是在本地转发，从而既可以减少核心网的资源也可以缩短转发V2X业务数据的时延的效果。According to the embodiment of the present invention, the V2X service data packet is sent to the target base station on the MBMS bearer corresponding to the V2X service type to which the V2X service data packet belongs, by using the application layer network element device disposed outside the core network, and the related information is solved. In the technology, a large number of V2X service data will be forwarded through the core network, causing the eNB to broadcast V2X service data with a large delay, and the V2X service data is forwarded locally without going through the core network element and the V2X AS. Therefore, the resources of the core network can be reduced, and the delay of forwarding the V2X service data can be shortened.

在本发明实施例中，增加了Application Layer(即上述的应用层网元设备)，用于接收UE(例如为OBU)发送的上行V2X业务数据包，并决定是否将该V2X业务数据包发送给其他UE，以及如何发送该V2X业务数据包。In the embodiment of the present invention, an application layer (that is, the application layer network element device) is added, and is configured to receive an uplink V2X service data packet sent by the UE (for example, an OBU), and determine whether to send the V2X service data packet to the Other UEs, and how to send the V2X service packets.

Application scenario of an application layer network element device As shown in FIG. 3, the application layer network element device in this embodiment is integrated in the source base station. At this time, the data of the UE is broadcast only in the range of one eNB; for example, the application layer network element device is The network element device connected to the source base station, that is, the application layer network element device is externally disposed as a logical entity. FIG. 4 is a schematic diagram of an application scenario of another application layer network element device in the method for transmitting data packets of the vehicle network service provided by the embodiment of the present invention.

A related base station; or, the target base station includes only one or more related base stations different from the source base station. When the application layer network element device can have an interface with multiple target base stations, the application layer network element device can broadcast the V2X service data packet in multiple target base stations. It should be noted that, if the application layer network element device is a network element device other than the source base station, the network element device is generally placed near the source base station, so as to shorten the delay of communication between the network element device and the source base station.

One or more predetermined base stations within the establishment establish an MBMS bearer, wherein each MBMS bearer established corresponds to a V2X service type.

在***初始化时，可以在应用层网元设备与包括目标基站在内的一个或多个预定基站建立MBMS承载，即与目标基站间建立数据通道，用于发送应用层网元设备到目标基站的下行V2X数据。该数据通道是每种V2X业务类型一条，应用层网元设备将不同业务类型的V2X数据分发到与之对应的数据通道上。相应地，目标基站也为每种V2X业务类型为该目标基站向所属的用户设备发送V2X业务数据包创建一个无线承载。目标基站将应用层网元设备与该目标基站间的数据通道与对应的无线承载做关联，当目标基站收到来自应用层网元设备的某一数据通道的V2X下行数据时，目标基站根据该关联关系，直接通过对应的无线承载发送数据。在实际应用中，应用层网元设备与目标基站间的数据通道可以通过用户层面的通用分组无线业务(General Packet Radio Server，简称为：GPRS)隧道协议(GPRS Tunnelling Protocol for the User Plane，简称为：GTP-U)的隧道端点标识(Tunnelling End Identity，简称为： TEID)标识，可选地，应用层网元设备与目标基站间的数据也可以通过组播地址标识。When the system is initialized, the application layer network element device and the one or more predetermined base stations including the target base station may establish an MBMS bearer, that is, establish a data channel with the target base station, and send the application layer network element device to the target base station. Downstream V2X data. The data channel is one type of each V2X service type, and the application layer network element device distributes V2X data of different service types to the corresponding data channel. Correspondingly, the target base station also creates a radio bearer for each V2X service type for the target base station to send a V2X service data packet to the associated user equipment. The target base station associates the data channel between the application layer network element device and the target base station with the corresponding radio bearer. When the target base station receives the V2X downlink data from a certain data channel of the application layer network element device, the target base station according to the The association relationship directly sends data through the corresponding radio bearer. In practical applications, the data channel between the application layer network element device and the target base station can pass the User Packet Radio Server (GPRS) protocol (the GPRS Tunneling Protocol for the User Plane). : Tunneling End Identity (GTP-U): TEID) identifier. Optionally, data between the application layer network element device and the target base station may also be identified by a multicast address.

可选地，在本实施的一种应用场景中，当***预先配置应用层网元设备与包括目标基站在内的一个或多个预定基站之间的MBMS承载，包括：***预先为应用层网元设备配置以下参数中的一项或多项：用户层面的通用分组无线业务隧道协议GTP-U隧道的隧道端点标识C-TEID、应用层网元设备的组播地址、临时移动组标识(Temporary Mobile Group Identifier，简称为：TMGI)、服务区域(Service Area)。这样，当应用层网元设备和目标基站启动时，应用层网元设备与目标基站间的MBMS承载，以及目标基站到其所属的用户设备之间的无线承载已经建立了，并且在目标基站上配置好了下行承载映射关系，该下行承载映射关系即应用层网元设备与目标基站之间的MBMS承载，与目标基站与其所属用户设备之间的无线承载之间的关系。Optionally, in an application scenario of the implementation, when the system pre-configures the MBMS bearer between the application layer network element device and one or more predetermined base stations including the target base station, the system is pre-configured as an application layer network. The meta-device configures one or more of the following parameters: the tunnel-end identifier C-TEID of the GTP-U tunnel at the user level, the multicast address of the application-layer NE device, and the temporary mobility group identifier (Temporary) Mobile Group Identifier, referred to as: TMGI), Service Area. In this way, when the application layer network element device and the target base station are activated, the MBMS bearer between the application layer network element device and the target base station, and the radio bearer between the target base station and the user equipment to which the target base station belongs are established, and on the target base station. The downlink bearer mapping relationship is configured, that is, the relationship between the MBMS bearer between the application layer network element device and the target base station, and the radio bearer between the target base station and the user equipment to which the user equipment belongs.

可选地，在本实施的另一种应用场景中，在应用层网元设备启动时，应用层网元设备与包括目标基站在内的一个或多个预定基站建立MBMS承载，包括：在应用层网元设备启动时，应用层网元设备接收MBMS GW配置的MBMS承载的以下参数中的一项或多项：GTP-U隧道的C-TEID、应用层网元设备的组播地址、临时移动组标识TMGI、服务区域(Service Area)。Optionally, in another application scenario of the implementation, when the application layer network element device is started, the application layer network element device establishes an MBMS bearer with one or more predetermined base stations including the target base station, including: When the layer network element device is started, the application layer network element device receives one or more of the following parameters of the MBMS bearer configured by the MBMS GW: the C-TEID of the GTP-U tunnel, the multicast address of the application layer network element device, and the temporary The mobile group identifies the TMGI and the service area.

可选地，在本实施的又一种应用场景中，在会话开始时，应用层网元设备与包括目标基站在内的一个或多个预定基站建立MBMS承载，包括：在会话开始时，应用层网元设备接收MBMS GW配置的MBMS承载的以下参数中的一项或多项：GTP-U隧道的C-TEID、应用层网元设备的组播地址、临时移动组标识TMGI、服务区域(Service Area)。Optionally, in another application scenario of the implementation, at the beginning of the session, the application layer network element is set.

在实际应用中，当应用层网元设备与目标基站间的MBMS承载是通过会话开始(Session Start)流程预建立时，需要增加应用层网元设备与MBMS GW的接口，并且将应用层网元设备的IP地址配置在MBMS GW的下行节点列表中。应用层网元设备的组播地址可由MBMS GW分配，也可以由应用层网元设备分配后发送给MBMS GW。MBMS GW需将TMGI、Service Area、V2X业务类型等信息发送给应用层网元设备。In an actual application, when the MBMS bearer between the application layer network element device and the target base station is pre-established through a session start process, the interface between the application layer network element device and the MBMS GW needs to be increased, and the application layer network element is added. The IP address of the device is configured in the downlink node list of the MBMS GW. The multicast address of the application layer network element device may be allocated by the MBMS GW, or may be allocated by the application layer network element device and then sent to the MBMS GW. The MBMS GW needs to send information such as the TMGI, Service Area, and V2X service type to the application layer network element device.

在本实施例的一种实现方式中，在会话开始时，应用层网元设备接收MBMS GW配置的MBMS承载的参数，包括：应用层网元设备接收MBMS GW发送的会话开始请求消息，其中，该会话开始请求消息中包括以下信息中的一项或多项：GTP-U隧道的C-TEID、临时移动组标识TMGI、服务区域Service Area以及对应的V2X业务类型；应用层网元设备分配所述组播地址；应用层网元设备将分配的组播地址、应用层网元设备在发送组播数据包时的源地址通过会话开始响应消息发送给MBMS GW。图5为本发明实施例提供的车联网业务数据包传输方法中一种建立MBMS承载的交互流程图，图5所示流程中的V2X业务对应的MBMS承载参数在MBMS承载预建立过程中通知给应用层的流程图，如图5所示，在会话开始(Session Start)流程中，该建立MBMS承载的流程包括以下步骤，即步骤201～步骤213：In an implementation manner of the embodiment, the application layer network element device receives the parameter of the MBMS bearer configured by the MBMS GW, and the application layer network element device receives the session start request message sent by the MBMS GW, where The session start request message includes one or more of the following information: a C-TEID of the GTP-U tunnel, a temporary mobility group identifier TMGI, a service area Service Area, and a corresponding V2X service type; an application layer network element device allocation office The multicast address is sent by the application layer network element device to the MBMS GW by using the session start response message when the multicast address of the application layer network element device and the application layer network element device sends the multicast data packet. FIG. 5 is a flowchart of an MBMS bearer interaction process in a method for transmitting a data packet of a car network service according to an embodiment of the present invention. The MBMS bearer parameter corresponding to the V2X service in the process shown in FIG. 5 is notified in the MBMS bearer pre-establishment process. The flowchart of the application layer is as shown in FIG. 5. In the session start process, the process of establishing an MBMS bearer includes the following steps, that is, steps 201 to 213:

步骤201，MBMS GW接收到BM-SC发送的会话开始请求消息；Step 201: The MBMS GW receives a session start request message sent by the BM-SC.

步骤202，MBMS GW向BM-SC发送会话开始响应消息；Step 202: The MBMS GW sends a session start response message to the BM-SC.

步骤204，应用层网元设备在收到会话开始请求消息后，分配组播地址；Step 204: After receiving the session start request message, the application layer network element device allocates a multicast address.

步骤205，应用层网元设备将组播地址及应用层网元设备在发送组播数据包时的源地址通过会话开始响应消息发送给MBMS GW；Step 205: The application layer network element device sends the multicast data to the multicast address and the application layer network element device. The source address of the packet is sent to the MBMS GW through a session start response message;

在后续流程中执行以下操作：Do the following in the subsequent process:

步骤206，MBMS GW向MME/SGSN发送会话开始请求消息；Step 206: The MBMS GW sends a session start request message to the MME/SGSN.

步骤213，MBMS GW向E-UTRAN/UTRAN发送MBMS数据。In step 213, the MBMS GW sends the MBMS data to the E-UTRAN/UTRAN.

在图5所示流程中，MBMS GW发送给下行节点(目标基站)的组播地址是由应用层网元设备分配的组播地址，组播源地址是应用层网元设备的地址。这样，当Session Start流程结束时，在应用层网元设备和目标基站间建立了MBMS承载，并且应用层也保存了足够的信息能将V2X业务数据包发送到对应的MBMS承载上。In the flow shown in FIG. 5, the multicast address sent by the MBMS GW to the downlink node (the target base station) is the multicast address allocated by the application layer network element device, and the multicast source address is the address of the application layer network element device. Thus, when the Session Start process ends, an MBMS bearer is established between the application layer network element device and the target base station, and the application layer also stores sufficient information to transmit the V2X service data packet to the corresponding MBMS bearer.

当多种V2X业务类型所对应的MBMS承载通过Session Start流程预建立后，MBMS GW已经保存了每个MBMS承载对应的参数，包括：TMGI、C-TEID、组播地址、Service Area等。此时，MBMS GW可将V2X对应的MBMS承载信息配置到应用层网元设备，即应用层网元设备获知一个或多个V2X业务类型所对应的MBMS承载，及每个MBMS承载所对应的配置信息/参数，上述方式包括以下步骤：After the MBMS bearer corresponding to the V2X service type is pre-established through the Session Start process, the MBMS GW has saved parameters corresponding to each MBMS bearer, including: TMGI, C-TEID, multicast address, Service Area, and the like. In this case, the MBMS GW can configure the MBMS bearer information corresponding to the V2X to the application layer network element device, that is, the application layer network element device learns the MBMS bearer corresponding to one or more V2X service types, and the configuration corresponding to each MBMS bearer. Information/parameters, the above method includes the following steps:

步骤1-1：应用层网元设备向MBMS GW发送请求消息，该请求消息用于获取V2X业务所配置的MBMS信息/参数；Step 1-1: The application layer network element device sends a request message to the MBMS GW, where the request message is used to obtain the MBMS information/parameters configured by the V2X service.

步骤1-2：MBMS GW向应用层网元设备发送响应消息，该响应消息中包括一个或多个V2X业务类型所对应的MBMS信息/参数，例如：V2X业务类型标识和唯一对应的TMGI标识。如：V2X业务类型<-->TMGIStep 1-2: The MBMS GW sends a response message to the application layer network element device, where the response message includes one or more MBMS information/parameters corresponding to the V2X service type, for example, a V2X service type identifier and a unique corresponding TMGI identifier. Such as: V2X business type <-->TMGI

还可以提供每种V2X业务类型所配置的MBMS承载的参数，该参数例如为：服务质量(Quality of Service，简称为：QoS)、多播/广播的区域、MBMS业务信道标识(逻辑控制标识(Logic Control ID，简称为：LCID)或者MBMS业务标识(MBMS Traffic ID，简称为：MTCH ID))、组播地址、C-TEID、等。It is also possible to provide parameters of the MBMS bearer configured for each V2X service type, such as parameters such as It is: Quality of Service (QoS), Multicast/Broadcast Area, MBMS Service Channel Identity (Logic Control ID (LCID) or MBMS Traffic ID (MBMS Traffic ID). It is: MTCH ID)), multicast address, C-TEID, and so on.

如：V2X业务类型<-->{TMGI，组播地址、C-TEID、QoS，service area，LCID/MTCH ID}Such as: V2X service type <--> {TMGI, multicast address, C-TEID, QoS, service area, LCID/MTCH ID}

MBMS GW也可以直接向应用层网元设备发送V2X业务的指示信息，即：没有上述的步骤1-1，仅有步骤1-2。The MBMS GW can also directly send the indication information of the V2X service to the application layer network element device, that is, without the above steps 1-1, only steps 1-2.

实际应用中，在一种V2X业务类型可能跨多个MBMS业务区域(Service Area)的情况下，为了简化UE的操作，对于不同区域的同一种V2X业务类型，可以采用同一个TMGI标识。这样，当UE移动时，UE毋须配置新的TMGI，从而降低获取V2X消息的时延。不同V2X业务类型的TMGI可预配置在UE中，或者UE通过网页、或者开放移动联盟终端管理(Open Mobile Alliance Device Management，简称为：OMA DM)配置模式等方式给UE配置TMGI。In a practical application, in a case where a V2X service type may span multiple MBMS service areas, the same TMGI identifier may be used for the same V2X service type in different areas in order to simplify the operation of the UE. In this way, when the UE moves, the UE does not need to configure a new TMGI, thereby reducing the delay in acquiring the V2X message. The TMGI of the different V2X service types may be pre-configured in the UE, or the UE may configure the TMGI through the webpage or the Open Mobile Alliance Device Management (OMA DM) configuration mode.

可选地，在本发明实施例中，还包括如下步骤：应用层网元设备接收源基站发送的待传输的V2X业务数据包时，还接收源基站发送的UE标识和小区标识，其中，UE标识用于指示发送V2X业务数据包的UE。这样应用层可以知道每个V2X业务数据包来自哪个OBU以及来自哪个小区的哪个源基站。Optionally, in the embodiment of the present invention, the method further includes the following steps: the application layer network element device receives the V2X service data packet to be transmitted sent by the source base station, and further receives the UE identifier and the cell identifier sent by the source base station, where the UE Identifies the UE that is used to indicate the sending of V2X service data packets. Thus the application layer can know which OBU each V2X service data packet comes from and which source base station from which cell.

上述已经说明，由于应用层网元设备已经获知每个V2X业务类型所对应的MBMS承载信息/参数，当应用层网元设备接收到V2X数据包之后，应用层网元设备读取V2X数据包的内容，判断出每个V2X数据包分别属于哪种V2X业务类型，然后应用层网元设备将每个V2X数据包分别承载到对应的MBMS承载上，并发送给目标基站。在实际应用中，上述应用层网元设备可以仅处理来自一个源基站的V2X业务数据包，例如，应用层网元设备承载在一个源基站上；另外，上述应用层网元设备也可以处理来自多个源基站的V2X业务数据包，此时应用层网元设备与该多个源基站相连接。As described above, since the application layer network element device has obtained the MBMS bearer information/parameter corresponding to each V2X service type, after the application layer network element device receives the V2X data packet, the application layer network element device reads the V2X data packet. The content is determined by which V2X service type each V2X data packet belongs to, and then the application layer network element device carries each V2X data packet to the corresponding MBMS bearer and sends it to the target base station. In an actual application, the application layer network element device can process only V2X service data packets from one source base station, for example, the application layer network element device is carried on a source base station; in addition, the application layer network element device can also process the V2X service data packets of multiple source base stations, at this time, the application layer network element device is connected to the multiple source base stations.

例如，当应用层网元设备接收/处理/发送来自一个或多个源基站的V2X业务数据包的时候，应用层网元设备接收到来自每一个源基站的V2X业务数据包后，根据每种V2X业务类型所需要广播的服务区域(Service Area)，选择对应的一个或多个目标基站，并在这个或者这些目标基站上发送。当V2X业务类型的广播区域中包括小区信息，上述这个或者这些目标基站可以地在相应的小区上发送。For example, when the application layer network element device receives/processes/transmits V2X service data packets from one or more source base stations, the application layer network element device receives the V2X service data packets from each source base station, according to each Service area to be broadcasted by the V2X service type, select Corresponding one or more target base stations are transmitted on the one or more target base stations. When the cell information is included in the broadcast area of the V2X service type, the one or more target base stations may be transmitted on the corresponding cell.

举例说明：for example:

假设：V2X业务类型1的广播的服务区域(Service Area)是eNB1，eNB2和eNB3；V2X业务类型2的广播的服务区域是eNB2和eNB3；It is assumed that the service areas of the V2X service type 1 broadcast are eNB1, eNB2 and eNB3; the service areas of the V2X service type 2 broadcast are eNB2 and eNB3;

当应用层接收到来自eNB1和eNB2的V2X业务后，根据每个V2X业务类型所对应的MBMS承载，将这些V2X业务分别承载在V2X业务类型1和V2X业务类型2的MBMS承载上，然后发送V2X业务类型1的数据包到eNB1，eNB2和eNB3；发送V2X业务类型2的数据包到eNB2和eNB3。After receiving the V2X service from the eNB1 and the eNB2, the application layer carries the V2X services on the MBMS bearers of the V2X service type 1 and the V2X service type 2, respectively, according to the MBMS bearer corresponding to each V2X service type, and then sends the V2X. The traffic type 1 packet is sent to eNB1, eNB2 and eNB3; the V2X service type 2 packet is transmitted to eNB2 and eNB3.

可选地，在本发明实施例提供中，在应用层网元设备在所确定的MBMS承载上将V2X业务数据包发送给目标基站之后，即步骤130之后，还可以包括：目标基站将V2X业务数据包广播给接入到目标基站的一个或多个UE。Optionally, in the embodiment of the present invention, after the application layer network element device sends the V2X service data packet to the target base station on the determined MBMS bearer, that is, after step 130, the target base station may further include: the target base station sends the V2X service. The data packet is broadcast to one or more UEs that are connected to the target base station.

在本发明实施例中，还提供了一种车联网业务数据包传输方法，图6为本发明实施例提供的另一种车联网业务数据包传输方法的流程图。如图6所示，本实施例提供的方法包括如下步骤，即步骤310～步骤330：In the embodiment of the present invention, a method for transmitting a data packet of a car network service is also provided. FIG. 6 is a flowchart of another method for transmitting a data packet of a car network service according to an embodiment of the present invention. As shown in FIG. 6, the method provided in this embodiment includes the following steps, that is, step 310 to step 330:

步骤310，源基站接收UE发送的V2X业务数据包；Step 310: The source base station receives the V2X service data packet sent by the UE.

步骤320，源基站从接收到的V2X业务数据包中确定待传输的V2X业务数据包；Step 320: The source base station determines, from the received V2X service data packet, a V2X service data packet to be transmitted.

步骤330，源基站将待传输的V2X业务数据包发送给应用层网元设备，以指示该应用层网元设备在与待传输的V2X业务数据包所属的V2X业务类型对应的MBMS承载上，将该待传输的V2X业务数据包发送给目标基站，其中，应用层网元设备设置在核心网之外，MBMS承载预先建立在应用层网元设备与目标基站之间。Step 330: The source base station sends the V2X service data packet to be transmitted to the application layer network element device, to indicate that the application layer network element device is on the MBMS bearer corresponding to the V2X service type to which the V2X service data packet to be transmitted belongs. The V2X service data packet to be transmitted is sent to the target base station, where the application layer network element device is set outside the core network, and the MBMS bearer is pre-established between the application layer network element device and the target base station.

本发明实施例提供的车联网业务数据包传输方法，通过设置在核心网之外的应用层网元设备，在与V2X业务数据包所属的V2X业务类型对应的多媒体广播多播业务MBMS承载上，将V2X业务数据包发送给目标基站，解决了相关技术中，大量的V2X业务数据会经过的核心网迂回，导致eNB广播发送 V2X业务数据时延过大的问题，实现了V2X业务数据不再经过核心网网元和V2X AS而是在本地转发，从而既可以减少核心网的资源也可以缩短转发V2X业务数据的时延的效果。The method for transmitting the data packet of the vehicle network service provided by the embodiment of the present invention is performed on the MBMS bearer of the multimedia broadcast multicast service corresponding to the V2X service type to which the V2X service data packet belongs, by using the application layer network element device outside the core network. The V2X service data packet is sent to the target base station, and the core network that the V2X service data passes through is recovered in the related art, and the eNB broadcasts and sends the packet. The V2X service data has a large delay. The V2X service data is forwarded locally instead of the core network element and the V2X AS. This reduces the resources of the core network and shortens the delay of forwarding V2X service data. effect.

The V2X service data packet is determined in the V2X service data packet, where the parameters of the received V2X service data packet include one or more of the following: a destination IP address in the V2X service data packet; and a V2X service data packet The identifier of the Packet Data Convergence Protocol (PDCP) header; the identifier of the bearer where the V2X service data packet is located; and the predetermined field in the V2X service data packet. Therefore, when receiving the user plane data packet, the source base station can determine which data packets are V2X service data packets that are normally sent to the core network, and which data packets are V2X service data packets that need to be sent to the application layer network element device.

可选地，在本发明实施例中，源基站根据接收到的V2X业务数据包的参数从该接收到的V2X业务数据包中确定待传输的V2X业务数据包的实现方式可以包括以下几种情况：Optionally, in the embodiment of the present invention, the implementation manner of determining, by the source base station, the V2X service data packet to be transmitted from the received V2X service data packet according to the received parameter of the V2X service data packet may include the following situations: :
