相关技术已经提出使用蜂窝无线通信技术来实现车联网应用的可能。如对应用于V2V以及V2P通信，基站可接收来自车辆UE或是行人UE的车联网信息，并传输发送给服务小区的车辆用户设备(User Equipment，简称UE)或行人UE。而V2I通常指车辆UE与路边单元(Road Side Unit，简称RSU)之间的通信，其中，RSU为支持V2I服务的实体，可从车辆UE接收车联网信息并传输发送至车辆UE。RSU可考虑由基站或静止的UE或独立的网元实现。Related art has proposed the possibility of implementing cellular networking applications using cellular wireless communication technologies. For corresponding V2V and V2P communication, the base station can receive the vehicle networking information from the vehicle UE or the pedestrian UE, and transmit the user equipment (User Equipment, UE for short) or the pedestrian UE transmitted to the serving cell. V2I generally refers to communication between a vehicle UE and a Road Side Unit (RSU), wherein the RSU is an entity supporting V2I service, and the vehicle networking information can be received from the vehicle UE and transmitted to the vehicle UE. The RSU can be considered to be implemented by a base station or a stationary UE or a separate network element.
在V2V/V2P/V2I车联网通信模式下，车联网信息的传输大多以广播和组播方式为主。现有***基站支持基于多播/组播单频网络(Multimedia Broadcast multicast serve single frequency network，简称MBSFN)以及单小区-点到多点(Single Cell-Point to Multi-point，简称SC-PTM)的广播机制，此外UE到UE的直接发现/通信(D2D，sidelink，ProSe)机制也可以支持通过PC5接口进行消息的广播传输。在这种情况下，UE选择使用Uu还是使用PC5接口传输车辆网信息，现有***尚未给出完善的解决方案。In the V2V/V2P/V2I car network communication mode, the transmission of car network information is mostly based on broadcast and multicast. The existing system base station supports a Multimedia Broadcast multicast serve single frequency network (MBSFN) and a Single Cell-Point to Multi-point (SC-PTM). The broadcast mechanism, in addition to the UE-to-UE direct discovery/communication (D2D, sidelink, ProSe) mechanism, can also support broadcast transmission of messages over the PC5 interface. In this case, the UE chooses to use Uu or uses the PC5 interface to transmit vehicle network information, and the existing system has not yet provided a complete solution.

As shown in FIG. 3a, a car network or a pedestrian UE may send car network related information to a base station through a Uu interface. The base station then forwards the information to the MBMS content provider/car network server through the core network, and then passes the information through the Broadcast Multicast Service Center (BMSC) and the multimedia broadcast multicast service (Multimedia Broadcast/ The Multicast Service (MBMS) gateway transmits the base station to the base station that needs to broadcast the car network information, and the base station transmits the car network information to the vehicle or pedestrian UE in the broadcast area including the own cell through the MBSFN/SC-PTM method.
图3b是根据本发明优选实施例的基站或基站充当的RSU基于蜂窝通讯进行车联网信息传输的网络架构图，如图3b所示，车联网或行人UE或UE类型的RSU可以通过Uu接口向基站发送车联网相关信息，基站将该信息经过核心网转发至车联网服务器，车联网服务器再将该信息通过分组数据网网关(Packet Data Network Gateway，简称PGW)/服务网关(Service Gateway，简称SGW)发送至需要进行车联网信息广播的基站，基站再将该车联网信息以单播方式发送给小区内的车辆或行人UE。 FIG. 3b is a network architecture diagram of an RSU that is used by a base station or a base station to perform car network information transmission based on cellular communication according to a preferred embodiment of the present invention. As shown in FIG. 3b, a car network or a pedestrian UE or a UE type RSU may be provided through a Uu interface. The base station sends the information related to the vehicle networking, and the base station forwards the information to the vehicle networking server through the core network, and the vehicle networking server passes the information through the Packet Data Network Gateway (PGW)/Service Gateway (SGW).

Information, the base station sends the car network information broadcast/multicast/unicast mode to the vehicle or pedestrian UE of the local cell. Figure 3d is a schematic illustration of vehicle networking information transmitted between vehicles via a PC5 interface in accordance with a preferred embodiment of the present invention.
需要说明的是，上述图3a至图3d也示出了车辆往可能出现的各种传输路径，比如图3d示出的是Sidelink传输路径。It should be noted that the above-mentioned FIG. 3a to FIG. 3d also show various transmission paths that the vehicle may appear, such as the Sidelink transmission path shown in FIG. 3d.
一般来说，车联网信息传输需要综合考虑延迟需求，广播传输范围，可用资源以及负荷情况。车联网信息传输对延迟要求较高，基于Uu的蜂窝传输需要经过多个网元的转发，其端到端延迟要比PC5接口传输大，如果基站支持本地网关或本地路由，则延迟可适当的降低。此外不同的车联网业务有不同的传输范围要求，基于Uu的MBMS以及SC-PTM通常可以实现较大的广播范围，而基于PC5接口的sidelink传输受限于发送功率，很难达到多个小区进行MBMS或SC-PTM广播对应的区域。此外UE或UE类型的RSU在选择路径时可以考虑Uu接口和PC5接口的可用资源以及负荷情况，尽可能实现两种接口资源的负荷均衡。除了考虑车联网信息发送的传输路径，车联网信息接收的传输路径也需要考虑，如UE可以根据感兴趣的业务类型判断需要接收哪个接口上发送的车联网信息。以下针对上述几种传输路径以及网络架构场景给出路径选择流程。In general, car network information transmission needs to consider delay requirements, broadcast transmission range, available resources and load conditions. Vehicle network information transmission has higher delay requirements. Uu-based cellular transmission needs to be forwarded by multiple network elements. The end-to-end delay is larger than that of PC5 interface. If the base station supports local gateway or local route, the delay can be appropriate. reduce. In addition, different car networking services have different transmission range requirements. Uu-based MBMS and SC-PTM can usually achieve a large broadcast range, while PC5-based sidelink transmission is limited by transmission power, and it is difficult to reach multiple cells. The area corresponding to the MBMS or SC-PTM broadcast. In addition, the UE or UE type RSU can consider the available resources and load conditions of the Uu interface and the PC5 interface when selecting a path, and implement load balancing of the two interface resources as much as possible. In addition to considering the transmission path of the car network information transmission, the transmission path of the car network information reception also needs to be considered. For example, the UE can determine which network information to be transmitted on the interface to be received according to the type of service of interest. The path selection process is given below for the above several transmission paths and network architecture scenarios.
优选实施例1Preferred embodiment 1
车辆A和B安装有具备车联网功能的UE1，UE2。UE1和UE2处于有演进的统一陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，简称E-UTRAN)网络覆盖状态，并且E-UTRAN网络支持车联网功能。Vehicles A and B are equipped with UE1 and UE2 with car networking functions. UE1 and UE2 are in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) network coverage state, and the E-UTRAN network supports the car networking function.
假设安装UE1的车辆A检测到车辆安全功能异常，车辆A希望能向周围的车辆发送失控警告信息。图4是根据本发明优选实施例1的路径选择方法的流程示意图，如图4所示，该流程包括：Assuming that the vehicle A in which the UE 1 is installed detects an abnormality in the vehicle safety function, the vehicle A desires to transmit a runaway warning message to the surrounding vehicles. 4 is a schematic flowchart of a path selection method according to a preferred embodiment 1 of the present invention. As shown in FIG. 4, the process includes:
步骤S402，UE1从V2X功能实体(function)获得失控告警业务对应的广播范围，UE授权的车联网传输范围以及延迟需求信息。Step S402, the UE1 obtains the broadcast range corresponding to the runaway alarm service, the vehicle network transmission range authorized by the UE, and the delay requirement information from the V2X function entity.
步骤S404，UE1检测到基站广播发送的***信息，其中包含可用于车联网传输的可用资源信息，传输延迟指示(相当于上述传输延迟信息)和传输范围信息。可用资源指用于低延时业务/车联网业务的资源，包括Sidelink发现资源或通信资源，和/或Uu通信资源。其中Sidelink发现资源或通信资源包括用于指示Sidelink发现发送资源或通信发送资源存在的信息；Sidelink发现接收资源池或通信接收资源池；Sidelink发现发送资源池或通信发送资源池；Sidelink发现发送异常资源池或通信发送异常资源池；Sidelink发现发送资源或通信发送资源；Sidelink发现发送半静态资源或通信发送半静态资源等。Uu通信资源包括上行蜂窝发送资源；上行半静态蜂窝发送资源；下行蜂窝接收资源；下行半静态蜂窝接收资源；下行MBMS或SC-PTM接收资源等。而传输延迟指示包括是否支持本地路由/本地网关、是否支持本地MBMS网关/本地BM-SC/本地车联网服务器、是否支持RSU、Uu传输延迟预估值，Uu传输延迟级 别等。传输范围包括Uu下行传输区域、MBMS广播区域、Sidelink传输区域。其中MBMS广播区域指网络或基站可支持的MBMS信息广播区域。Sidelink传输区域可通过Sidelink传输最大发送功率来指示，或者通过不同Sidelink发送功率级别及对应的最大发送功率来指示，UE可通过上述信息计算sidelink传输对应的发送功率，从而得出sidelink传输区域大小。此外，Sidelink传输区域还可以通过对应于不同Sidelink发现/通信资源池的授权范围集合来指示。Step S404, the UE1 detects system information broadcasted by the base station, and includes available resource information, a transmission delay indication (corresponding to the above transmission delay information), and transmission range information, which are usable for the car network transmission. Available resources refer to resources used for low latency services/car networking services, including Sidelink discovery resources or communication resources, and/or Uu communication resources. The Sidelink discovery resource or communication resource includes information indicating that the Sidelink discovers the transmission resource or the communication transmission resource exists; Sidelink discovers the reception resource pool or the communication reception resource pool; Sidelink discovers the transmission resource pool or the communication transmission resource pool; and Sidelink finds that the abnormal resource is sent. The pool or communication sends an abnormal resource pool; Sidelink finds that the resource or communication sends the resource; Sidelink finds that the semi-static resource is sent or the semi-static resource is sent by communication. Uu communication resources include uplink cellular transmission resources; uplink semi-static cellular transmission resources; downlink cellular reception resources; downlink semi-static cellular reception resources; downlink MBMS or SC-PTM reception resources, and the like. The transmission delay indication includes whether to support local routing/local gateway, whether to support local MBMS gateway/local BM-SC/local car network server, whether to support RSU, Uu transmission delay estimation value, Uu transmission delay level Don't wait. The transmission range includes a Uu downlink transmission area, an MBMS broadcast area, and a Sidelink transmission area. The MBMS broadcast area refers to an MBMS information broadcast area that the network or the base station can support. The Sidelink transmission area can be indicated by the transmission of the maximum transmission power by the Sidelink, or by the different Sidelink transmission power level and the corresponding maximum transmission power. The UE can calculate the transmission power corresponding to the sidelink transmission by using the above information, thereby obtaining the size of the sidelink transmission area. In addition, the Sidelink transmission area can also be indicated by a set of authorization ranges corresponding to different Sidelink discovery/communication resource pools.
步骤S406，UE将上述信息上报给高层，高层决定业务信息通过Sidelink传输路径还是Uu传输路径来传输。UE还可上报高层传输范围和传输延迟指示，高层可根据传输延迟信息判断信息传输的延迟情况，如果基站不支持本地网关/本地路由/本地MBMS网关/本地BM-SC/本地车联网服务器/RSU，则数据包传输延迟较长，UE可首选Sidelink传输路径，否则UE选择Uu传输路径；UE还可根据Uu传输延迟预估值或是延迟级别判断是否满足低延迟业务的延迟需求，如果不满足，则选择Sidelink传输路径。假设UE1的高层发现有Uu传输资源，且Uu传输路径可以满足延迟要求和广播区域要求，则选择Uu传输路径.In step S406, the UE reports the above information to the upper layer, and the upper layer determines whether the service information is transmitted through the Sidelink transmission path or the Uu transmission path. The UE may also report the high-level transmission range and the transmission delay indication, and the upper layer may determine the delay of the information transmission according to the transmission delay information, if the base station does not support the local gateway/local routing/local MBMS gateway/local BM-SC/local car network server/RSU , the packet transmission delay is long, the UE may prefer the Sidelink transmission path, otherwise the UE selects the Uu transmission path; the UE may also determine whether the delay requirement of the low-latency service is satisfied according to the Uu transmission delay estimation value or the delay level, if not satisfied , select the Sidelink transmission path. Assuming that the upper layer of UE1 finds Uu transmission resources, and the Uu transmission path can meet the delay requirement and the broadcast area requirement, the Uu transmission path is selected.
步骤S408，高层指示AS层通过Uu传输路径传输车联网数据包。Step S408, the upper layer instructs the AS layer to transmit the car network data packet through the Uu transmission path.
该数据包发送到服务基站后，服务基站将该信息经过SGW/PGW转发至MBMS的内容提供者/车联网服务器，再将该信息通过BMSC以及MBMS网关传送至需要进行车联网信息广播的基站，如基站2.基站2将该车联网信息通过SC-PTM方式发送给小区内的车辆或行人UE。After the data packet is sent to the serving base station, the serving base station forwards the information to the content provider/vehicle network server of the MBMS through the SGW/PGW, and then transmits the information to the base station that needs to broadcast the car network information through the BMSC and the MBMS gateway. For example, the base station 2 transmits the car networking information to the vehicle or pedestrian UE in the cell through the SC-PTM mode.
假设基站2覆盖范围内的车辆UE2对接收车联网信息感兴趣，则UE2检测感兴趣的车联网业务对应的组无线网络临时标识(Group Radio Network Temporary Identifier，简称G-RNTI),并在相应的物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)上接收车联网消息。完成车联网信息接收后，UE2解析包含车联网信息的数据包，将包含车联网信息的数据包投递给逻辑信道/RLC接收实体/PDCP接收实体，最终将解析出来的车联网消息投递给高层。UE2的车联网协议层接收到车联网消息后，UE2进一步判断该信息是否与安装UE2的车辆相关，并向驾驶员发出提示或警告。It is assumed that the vehicle UE2 in the coverage area of the base station 2 is interested in receiving the car network information, and the UE2 detects the Group Radio Network Temporary Identifier (G-RNTI) corresponding to the car network service of interest, and correspondingly The vehicle downlink message is received on the Physical Downlink Shared Channel (PDSCH). After completing the car network information reception, the UE2 parses the data packet including the car network information, and delivers the data packet including the car network information to the logical channel/RLC receiving entity/PDCP receiving entity, and finally delivers the parsed car network message to the upper layer. After receiving the Internet of Vehicles message from the car networking protocol layer of UE2, UE2 further determines whether the information is related to the vehicle in which UE2 is installed, and issues a prompt or warning to the driver.
UE1高层选择使用Uu进行上行传输后，如果接入层(Access Stratum，简称AS)检测出现了空口链路失败时，AS层可向高层上报Sidelink异常资源池和或Sidelink发送资源池信息，高层可选择切换到Sidelink异常资源池或Sidelink发送资源池通过Sidelink资源进行信息传输。After the upper layer of the UE1 is selected to use Uu for uplink transmission, if the Access Stratum (AS) detects that the air interface link fails, the AS layer can report the Sidelink abnormal resource pool and the Sidelink sending resource pool information to the upper layer. Select to switch to the Sidelink exception resource pool or the Sidelink send resource pool for information transmission via the Sidelink resource.

UE1 and UE2 are in an E-UTRAN network coverage state, and the E-UTRAN network supports the car networking function. When the vehicle A in which the UE 1 is installed suddenly stops in the middle of the road, the vehicle networking application layer of the UE 1 generates a warning vehicle warning DEMN message, which is desired to be transmitted to the surrounding vehicles.
图5是根据本发明优选实施例2的路径选择方法的流程示意图，如图5所示，该流程包括：FIG. 5 is a schematic flowchart of a path selection method according to a preferred embodiment 2 of the present invention. As shown in FIG. 5, the process includes:

Situation, transmission range information. The load case may include information for indicating a request for prohibition or use of a Sidelink resource; information for indicating a request for prohibition or use of a Sidelink resource timer; information for indicating a request for prohibition or use of a priority or priority set of Sidelink resources; Information indicating a low-latency service type or type set for prohibiting the request or using the Sidelink resource; information indicating the load of the Sidelink resource; wherein the information includes at least one of: Sidelink resource usage level or congestion level; Information for requesting or using Uu uplink cellular resources; information for indicating prohibition of request or use of Uu uplink cellular resource timer; information for indicating prohibition of request or use of priority or priority set of Uu uplink cellular resources; Information indicating a low-latency service type or type set for prohibiting the request or using the Uu uplink resource; information for indicating MBMS downlink broadcast resource congestion; information for indicating a frequency of reducing low-latency service information transmission; for indicating low recovery Information about the frequency at which the service information is sent. The transmission range includes a Uu downlink transmission area, an MBMS broadcast area, and a Sidelink transmission area. The MBMS broadcast area refers to an MBMS information broadcast area that the network or the base station can support. The Sidelink transmission area can be indicated by the transmission of the maximum transmission power by the Sidelink, or by the different Sidelink transmission power level and the corresponding maximum transmission power. The UE can calculate the transmission power corresponding to the sidelink transmission by using the above information, thereby obtaining the size of the sidelink transmission area. In addition, the Sidelink transmission area can also be indicated by a set of authorization ranges corresponding to different Sidelink discovery/communication resource pools.
步骤S504，UE根据负荷情况信息检测Uu上行资源，Sidelink资源负荷情况，如果禁止请求/使用Sidelink资源或Sidelink资源负荷高，则选择Uu传输路径；如果指示禁止请求或使用Sidelink资源定时器，则UE可开启禁止请求/使用Sidelink资源定时器，当定时器超时时，UE可继续考虑使用Sidelink资源；如果禁止请求/使用Uu上行蜂窝资源或Uu上行蜂窝资源负荷高，则选择Sidelink传输路径；如果指示禁止请求或使用Uu资源定时器，则UE可开启禁止请求/使用Uu资源定时器，当定时器超时时，UE可继续考虑使用Uu资源；如果同时禁止请求/使用Sidelink资源和Uu上行蜂窝资源，则UE暂停低延时业务传输；如果负荷情况指示禁止某个优先级或是某种业务类型使用Sidelink或Uu上行蜂窝资源，则UE使用Uu传输路径或Sidelink传输路径传输对应业务类型的车联网信息；如果负荷情况指示降低或恢复低延时业务信息发送频率指示，则UE发送给高层，由高层减低发送频率或恢复发送频率；如果指示指示MBMS下行广播资源拥塞的信息，则UE可选择减少车联网信息的发送频率，或是选择使用Sidelink传输路径进行传输，此外拥塞信息还可以设置不同的拥塞级别，当拥塞级别为高时，UE才选择使用Sidelink传输路径进行传输。假设UE1检测到MBMS下行广播资源拥塞指示，且Sidelink通信的传输区域可以紧急停车业务的广播范围要求，则选择Sidelink传输路径。Step S504, the UE detects the Uu uplink resource according to the load situation information, and the Sidelink resource load situation, if the request/use of the Sidelink resource or the Sidelink resource load is high, the Uu transmission path is selected; if the prohibition request is indicated or the Sidelink resource timer is used, the UE The prohibition request/use of the Sidelink resource timer may be enabled. When the timer expires, the UE may continue to consider using the Sidelink resource; if the request/use of the Uu uplink cellular resource or the Uu uplink cellular resource load is prohibited, the Sidelink transmission path is selected; If the request or the Uu resource timer is forbidden, the UE may enable the prohibition request/UU resource timer. When the timer expires, the UE may continue to consider using the Uu resource; if the request/use of the Sidelink resource and the Uu uplink cellular resource are simultaneously prohibited, Then, the UE suspends the low-latency service transmission; if the load condition indicates that a certain priority or a certain service type is used to use the Sidelink or Uu uplink cellular resources, the UE uses the Uu transmission path or the Sidelink transmission path to transmit the vehicle network information of the corresponding service type. ; if the load condition indicates a decrease or restore a low delay If the service information transmission frequency indication is sent to the upper layer, the UE reduces the transmission frequency or restores the transmission frequency. If the indication indicates that the MBMS downlink broadcast resource is congested, the UE may choose to reduce the transmission frequency of the car network information, or select to use Sidelink. The transmission path is transmitted. In addition, the congestion information can also be set to different congestion levels. When the congestion level is high, the UE selects to use the Sidelink transmission path for transmission. Assuming that the UE1 detects the MBMS downlink broadcast resource congestion indication, and the transmission area of the Sidelink communication can meet the broadcast range requirement of the emergency parking service, the Sidelink transmission path is selected.
步骤S506，高层指示AS层通过Sidelink传输车联网数据包。In step S506, the upper layer instructs the AS layer to transmit the car network data packet through the Sidelink.
UE1附近的车辆UE2对接收车联网信息感兴趣，则UE2获取***信息广播的Sidelink通信接收资源池信息，监听通过PC5接口传输的车联网信息。接收到UE1发来的车联网信息后，UE2解析包含车联网信息的数据包，并将包含车联网信息的数据包投递给车联网承载对应的逻辑信道/RLC接收实体/分组数据汇聚协议(Packet Data Convergence Protocol，简称PDCP)接收实体，最终将解析出来的警示车辆告警DENM消息投递给高层或车联网协议层。UE2的车联网协议层接收到警示车辆告警DENM消息后，UE2进一步判断该事件是否与安装UE2的车辆相关，并向驾驶员发出警告。 The vehicle UE2 near the UE1 is interested in receiving the car network information, and the UE2 acquires the Sidelink communication receiving resource pool information of the system information broadcast, and listens to the car network information transmitted through the PC5 interface. After receiving the car network information sent by the UE1, the UE2 parses the data packet including the car network information, and delivers the data packet including the car network information to the logical channel/RLC receiving entity/packet data convergence protocol (Packet) corresponding to the car network bearer. The Data Convergence Protocol (PDCP) receiving entity finally delivers the parsed alert vehicle warning DENM message to the upper layer or the car networking protocol layer. After receiving the warning vehicle warning DENM message, the UE2's car networking protocol layer further determines whether the event is related to the vehicle in which the UE2 is installed, and issues a warning to the driver.
