Technical field

This application relates to, but is not limited to, the field of communication technology.

Background technique

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.

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.

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.

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).

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.

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.

Optionally, in the embodiment of the present invention, the application layer network element device and the one or more predetermined base stations including the target base station may establish an MBMS bearer in multiple manners. For example, the following manner may be adopted. One:

In a first mode, the system pre-configures an MBMS bearer between the application layer network element device and one or more predetermined base stations including the target base station;

In the second mode, 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;

In a third mode, at the beginning of the session, the application layer network element device establishes an MBMS bearer with one or more predetermined base stations including the target base station. The MBMS bearer establishment manners in the above several manners are respectively described below.

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.

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.

Optionally, in another application scenario of the implementation, at the beginning of the session, the application layer network element is set. Establishing an MBMS bearer with one or more predetermined base stations including the target base station, including: at the beginning of the session, the application layer network element device receives one or more of the following parameters of the MBMS bearer configured by the MBMS GW: GTP- The C-TEID of the U tunnel, the multicast address of the application layer NE device, the temporary mobility group identifier TMGI, and the service area.

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.

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:

Step 201: The MBMS GW receives a session start request message sent by the BM-SC.

Step 202: The MBMS GW sends a session start response message to the BM-SC.

Step 203: The MBMS GW sends a session start request message to the application layer network element device, and sends a message such as a TMGI, a service area, a C-TEID, and a corresponding V2X service type to the application layer network element device.

Step 204: After receiving the session start request message, the application layer network element device allocates a multicast address.

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;

Do the following in the subsequent process:

Step 206: The MBMS GW sends a session start request message to the MME/SGSN.

Step 207: The MME/SGSN sends a session start request message to the E-UTRAN/UTRAN.

Step 208: The E-UTRAN/UTRAN sends a session start response message to the MBMS GW.

Step 209: The MME/SGSN sends a session start response message to the MBMS GW.

Step 210: The E-UTRAN/UTRAN performs RAN resource establishment.

Step 211, E-UTRAN/UTRAN joins IP multicast;

Step 212: The BM-SC sends MBMS data to the MBMS GW.

In step 213, the MBMS GW sends the MBMS data to the E-UTRAN/UTRAN.

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.

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:

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.

Step 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

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.

Such as: V2X service type <--> {TMGI, multicast address, C-TEID, QoS, service area, LCID/MTCH ID}

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.

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.

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.

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.

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.

for example:

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;

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.
