技术领域Technical field
本申请涉及通信技术领域,尤其涉及一种通信方法及通信装置。This application relates to the field of communication technology, and in particular, to a communication method and a communication device.
背景技术Background technique
随着通信技术的发展,在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)中提出了基于蜂窝网络的车到所有(vehicle to everything,V2X)。V2X是将车辆与一切事物相连接的新一代信息通信技术,其中,V代表车辆,X代表任何与车交互信息的对象,例如包括车、人、交通路侧基础设施和网络,因此,V2X交互的信息模式可以包括车到车(vehicle to vehicle,V2V)、车到人(vehicle to pedestrian,V2P)、车到基础设施(vehicle to infrastructure,V2I)和车到网络(vehicle to network,V2N)的交互等。With the development of communication technology, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) has proposed a vehicle-to-everything (V2X) based on cellular networks. V2X is a new generation of information and communication technology that connects vehicles to everything. Among them, V stands for vehicles and X stands for any object that interacts with vehicles, such as vehicles, people, and roadside infrastructure and networks. Therefore, V2X interaction The information model can include vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), vehicle-to-infrastructure (V2I) and vehicle-to-network (V2N). Interaction, etc.
在长期演进(long term evolution,LTE)系统中,为V2X引入了一套业务质量(quality of service,QoS)参数,以解决网络延迟和阻塞等问题。目前,在LTE V2X系统中,QoS参数的管理主要是基于单包优先级(prose per packet priority,PPPP)和单包可靠性(prose per packet reliability,PPPR)进行的。在LTE系统中,通常是通信装置的应用层产生数据包,之后应用层将该数据包和指定该数据包的优先级发送至V2X层,V2X层根据该数据包的指定优先级确定出PPPP和/或PPPR,之后V2X层将该数据包、确定的PPPP和/或PPPR发送至通信装置的接入层(access stratum,AS),AS配置PPPP和/或PPPR,与逻辑信道或逻辑信道组的映射关系,之后通信装置的AS基于PPPP和/或PPPR进行V2X业务通信。例如,AS接收到两个数据包,根据该两个数据包的PPPP和/或PPPR,确定数据包a的优先级高于数据包b,并且当前时频资源紧缺,则AS可以优先发送数据包a,之后再发送数据包b。In the long term evolution (LTE) system, a set of quality of service (QoS) parameters is introduced for V2X to solve network delay and blocking problems. At present, in the LTE V2X system, the management of QoS parameters is mainly based on single-packet priority (proseper packet priority, PPPP) and single-packet reliability (prose perpacket reliability, PPPR). In the LTE system, the application layer of the communication device usually generates a data packet, and then the application layer sends the data packet and the priority of the specified data packet to the V2X layer. The V2X layer determines the PPPP and the PPPP according to the specified priority of the data packet. /Or PPPR, and then the V2X layer sends the packet, the determined PPPP and/or PPPR to the access stratum (AS) of the communication device, the AS configures PPPP and/or PPPR, and the logical channel or logical channel group Mapping relationship, the AS of the communication device then performs V2X service communication based on PPPP and/or PPPR. For example, if the AS receives two data packets, according to the PPPP and/or PPPR of the two data packets, it is determined that the priority of the data packet a is higher than the data packet b, and the current time-frequency resources are scarce, then the AS can send the data packet first a, and then send the data packet b.
在新空口(new radio,NR)V2X系统中,QoS参数的管理是基于QoS流标识(QoS Flow ID,QFI)和/或第5代QoS指示符(5G QoS indicator,5QI)。在通信装置的V2X层确定出QFI和/或5QI后,AS配置QFI和/或5QI,与逻辑信道或逻辑信道组的映射关系,之后通信装置的AS基于QFI和/或5QI进行V2X业务通信。In the new radio (NR) V2X system, the management of QoS parameters is based on QoS flow identification (QoS Flow ID, QFI) and/or 5th generation QoS indicator (5G QoS indicator (5QI). After the V2X layer of the communication device determines the QFI and/or 5QI, the AS configures the mapping relationship between QFI and/or 5QI and the logical channel or logical channel group, and then the AS of the communication device performs V2X service communication based on the QFI and/or 5QI.
然而,NR V2X系统中的QoS管理机制与LTE V2X系统中的QoS管理机制不相同,比如,LTE V2X系统目前无法识别NR V2X系统中的QoS参数,如QFI和/或5QI。因此,若使现有的LTE V2X系统中的QoS参数管理机制能识别出NR V2X系统中的QoS参数,则需要更改LTE V2X系统中的QoS参数管理机制,如此,会增大LTE V2X系统中QoS参数管理机制的复杂度。However, the QoS management mechanism in the NR V2X system is different from the QoS management mechanism in the LTE V2X system. For example, the LTE V2X system cannot currently recognize the QoS parameters in the NR V2X system, such as QFI and/or 5QI. Therefore, if the existing QoS parameter management mechanism in the LTE V2X system can recognize the QoS parameter in the NR V2X system, the QoS parameter management mechanism in the LTE V2X system needs to be changed, so that the QoS in the LTE V2X system will be increased The complexity of the parameter management mechanism.

When it is determined that the first wireless direct communication interface is used to send the first data packet, the first The first QoS parameter corresponding to a data packet, the first wireless direct communication interface can recognize the first QoS parameter. In this way, when the first wireless direct communication interface using the first wireless access technology sends the first data packet, the existing mechanism for determining QoS parameters can be changed, and the first wireless direct communication interface can identify the first A QoS parameter.
示例性地,本申请提供如下两种确定用于发送第一数据包的第一无线接入技术的实现方式。Exemplarily, the present application provides the following two implementation manners of determining the first wireless access technology for sending the first data packet.
实现方式一Implementation method one
第一通信装置的第一层从第一通信装置的第二层接收指示信息,指示信息用于指示第一业务对应的第一无线接入技术,第一数据包属于第一业务,第一通信装置的第一层根据指示信息,确定用于发送第一数据包的第一无线接入技术。The first layer of the first communication device receives indication information from the second layer of the first communication device, the indication information is used to indicate the first wireless access technology corresponding to the first service, the first data packet belongs to the first service, the first communication The first layer of the device determines the first wireless access technology for sending the first data packet according to the instruction information.

针对第一无线接入技术为NR技术的情况下,可根据指示信息中的通信类型,确定第一QoS参数。一种可能的实现方式,若通信类型为单播或组播,则第一通信装置的第一层确定第一QoS参数为QFI,若通信类型为广播,则第一通信装置的第一层确定第一QoS参数为5QI。如此,对于通信类型为单播或者组播时,通过QFI标识第一QoS参数,有助于减小第一通信装置数据的传输量。For the case where the first radio access technology is the NR technology, the first QoS parameter may be determined according to the communication type in the indication information. A possible implementation manner, if the communication type is unicast or multicast, the first layer of the first communication device determines that the first QoS parameter is QFI, and if the communication type is broadcast, the first layer of the first communication device determines The first QoS parameter is 5QI. In this way, when the communication type is unicast or multicast, identifying the first QoS parameter by QFI helps to reduce the data transmission amount of the first communication device.

作为示例,本申请提供如下两种实现方式来确定用于发送第一数据包的第一无线接入技术。As an example, the present application provides the following two implementation manners to determine the first wireless access technology for sending the first data packet.
实现方式一Implementation method one
第一通信装置可获取指示信息,根据指示信息,确定用于发送第一数据包的第一无线接入技术,示例性的,指示信息用于指示第一业务对应的第一无线接入技术,第一数据包属于第一业务。本申请中,第一业务也可以是标识业务,也可以标识业务类型,本申请不做限定。在一种可能的实现方式中,第一通信装置可以从基站获取第一指示信息,也可以从核心网(例如核心网中的CF节点、或者是具备V2X控制功能的其他节点)获取指示信息,也可以自己配置第一指示信息。The first communication device may acquire indication information, and determine the first wireless access technology for sending the first data packet according to the indication information. Exemplarily, the indication information is used to indicate the first wireless access technology corresponding to the first service, The first data packet belongs to the first service. In this application, the first service may also be an identification service or a service type, which is not limited in this application. In a possible implementation manner, the first communication device may acquire the first indication information from the base station, or may acquire the indication information from the core network (for example, a CF node in the core network or other nodes with V2X control functions), You can also configure the first indication information yourself.
在一种可能的实施方式中,指示信息可包括第一无线接入技术。第一无线接入技术和第一业务之间存在映射关系。示例性地,指示信息中包括多个按顺序排列的无线接入技术,第一通信装置可获取多个按顺序排列的业务,无线接入技术列表的顺序与业务列表的顺序一致,默认无线接入列表中的每一项与无线接入技术列表中的每一项一一对应。当第一通信装置获取到按顺序排列的无线接入技术和第一数据包后,先确定第一数据包所属的第一业务,按照第一业务在业务列表中的位置,确定无线接入技术列表中相同位置的那一项即为第一业务对应的第一无线接入技术。In a possible implementation manner, the indication information may include the first wireless access technology. There is a mapping relationship between the first radio access technology and the first service. Exemplarily, the indication information includes multiple wireless access technologies arranged in order. The first communication device may acquire multiple services arranged in sequence. The order of the wireless access technology list is consistent with the order of the service list. The default wireless access Each entry in the list corresponds to each entry in the wireless access technology list. After the first communication device obtains the wireless access technology and the first data packet arranged in sequence, first determine the first service to which the first data packet belongs, and determine the wireless access technology according to the position of the first service in the service list The item at the same position in the list is the first wireless access technology corresponding to the first service.
在另一种可能的实施方式,指示信息包括第一业务。第一业务和第一无线接入技术之间存在映射关系。示例性地,指示信息中包括的第一业务对应的无线接入技术是第一无线接入技术,指示信息中未包括的业务对应的无线接入技术是第二无线接入技术。或者,指 示信息中包括的第一业务对应的无线接入技术是第二无线接入技术,指示信息中未包括的业务对应的无线接入技术是第一无线接入技术。第一通信装置确定第一数据包属于第一业务,则可确定用于发送第一数据包的无线接入技术为第一无线接入技术。In another possible implementation manner, the indication information includes the first service. There is a mapping relationship between the first service and the first radio access technology. Exemplarily, the radio access technology corresponding to the first service included in the indication information is the first radio access technology, and the radio access technology corresponding to the service not included in the indication information is the second radio access technology. Or, the radio access technology corresponding to the first service included in the indication information is the second radio access technology, and the radio access technology corresponding to the service not included in the indication information is the first radio access technology. The first communication device determines that the first data packet belongs to the first service, and may determine that the wireless access technology used to send the first data packet is the first wireless access technology.
在又一种可能的实施方式中,指示信息可包括第一业务和第一无线接入技术,第一业务和第一无线接入技术之间存在映射关系。当第一通信装置确定第一数据包属于第一业务,则可以直接确定出与第一业务存在映射关系的第一无线接入技术。In yet another possible implementation manner, the indication information may include the first service and the first wireless access technology, and there is a mapping relationship between the first service and the first wireless access technology. When the first communication device determines that the first data packet belongs to the first service, it can directly determine the first wireless access technology that has a mapping relationship with the first service.
实现方式二Implementation method two

The auxiliary information includes at least one of the following: channel busy rate (CBR) corresponding to wireless direct connection communication interfaces of different wireless access technologies, priority corresponding to wireless direct connection communication interfaces of different wireless access technologies, A wireless direct communication interface covering a wireless access technology supported by the current cell of the first communication device; exemplarily, the first wireless access technology is any one of the wireless access technologies.
在一些实施例中,若覆盖第一通信装置的当前小区仅支持LTE V2X,则第一通信装置可确定通过LTE V2X SL发送第一数据包。若覆盖第一通信装置的当前小区仅支持NR V2X,则第一通信装置可确定通过NR V2X SL发送第一数据包。In some embodiments, if the current cell covering the first communication device only supports LTE V2X, the first communication device may determine to send the first data packet through LTE V2X SL. If the current cell covering the first communication device only supports NR V2X, the first communication device may determine to send the first data packet through NR V2X SL.
在另一些实施例中,可不考虑覆盖第一通信装置的当前小区所支持的无线接入技术,即可以理解为覆盖第一通信装置的当前小区支持的LTE V2X和NR V2X。第一通信装置可根据不同无线接入技术的直连通信接口的测量结果,和/或,不同无线接入技术的直连通信接口的优先级,确定用于发送第一数据包的第一无线接入技术。测量结果可以是CBR。例如,实现方式a,若第一通信装置确定LTE V2X SL的测量结果比NR V2X SL的测量结果差,例如LTE V2X SL对应的CBR大于NR V2X SL对应的CBR,即LTE V2X SL负载比NR V2X SL的负载高,则可确定用NR V2X SL发送第一数据包,即确定用于发送第一数据包的第一无线接入技术为NR技术。实现方式b,若第一通信装置确定LTE V2X SL的测量结果比NR V2X SL的测量结果好,例如第一通信装置确定LTE V2X SL对应的CBR不大于NRV2X SL对应的CBR,即LTE V2X SL负载比NR V2X SL的负载低,则可确定用LTE V2X SL发送第一数据包,即确定用于发送第一数据包的第一无线接入技术为LTE技术。实现方式c,若第一通信装置确定LTE V2X SL的测量结果较差、且确定NR V2X SL的测量结果较好,例如第一通信装置确定LTE V2X SL对应的CBR满足第一阈值,且NR V2X SL对应的CBR不满足第二阈值,则可确定用于发送第一数据包的第一无线接入技术为NR技术。实现方式d,若第一通信装置确定LTE V2X SL的测量结果较好、且确定NR V2X SL的测量结果较差,例如第一通信装置确定LTE V2X SL对应的CBR不满足第一阈值,且NR V2X SL对应的CBR满足第二阈值,则可确定用于发送第一数据包的第一无线接入技术为LTE技术。实现方式e,针对某些V2X业务,LTE V2X SL优先;针对另一些V2X业务,NR V2X SL优先等,一种可能的实现中,第一通信装置可以先从核心网或者基站或者从本地获取V2X业务对应的RAT V2X SL优先级的配置。实现方式f,若第一通信装置确定LTE V2X SL的测量结果和NR V2X SL的测量结果比较接近,例如第一通信装置确定LTE V2X SL对应的CBR不满足第一阈值,且NR V2X SL对应的CBR满足第二阈值,可确定第一数据包所属第一业务的优先级。In other embodiments, the wireless access technology supported by the current cell covering the first communication device may not be considered, that is, it may be understood to cover the LTE V2X and NR V2X supported by the current cell of the first communication device. The first communication device may determine the first wireless device for transmitting the first data packet according to the measurement result of the directly connected communication interfaces of different wireless access technologies, and/or the priority of the directly connected communication interfaces of different wireless access technologies Access technology. The measurement result may be CBR. For example, in implementation manner a, if the first communication device determines that the measurement result of LTE V2X SL is worse than the measurement result of NR V2X SL, for example, the CBR corresponding to LTE V2X SL is greater than the CBR corresponding to NR V2X SL, that is, the load ratio of LTE V2X SL to NR V2X If the load of SL is high, it can be determined that NR V2X SL is used to send the first data packet, that is, the first wireless access technology used to send the first data packet is the NR technology. Implementation method b, if the first communication device determines that the measurement result of LTE V2X SL is better than the measurement result of NR V2X SL, for example, the first communication device determines that the CBR corresponding to LTE V2X SL is not greater than the CBR corresponding to NRV2X SL, that is, the load of LTE V2X SL If the load is lower than that of NR V2X SL, it can be determined that LTE V2X SL is used to send the first data packet, that is, the first wireless access technology used to send the first data packet is LTE technology. Implementation manner c, if the first communication device determines that the measurement result of LTE V2X SL is poor and the measurement result of NR V2X SL is better, for example, the first communication device determines that the CBR corresponding to LTE V2X SL meets the first threshold and NR V2X If the CBR corresponding to the SL does not satisfy the second threshold, it may be determined that the first radio access technology used to send the first data packet is the NR technology. Implementation method d, if the first communication device determines that the measurement result of LTE V2X SL is better, and determines that the measurement result of NR V2X SL is poor, for example, the first communication device determines that the CBR corresponding to LTE V2X SL does not meet the first threshold, and the NR The CBR corresponding to V2X SL meets the second threshold, and it can be determined that the first wireless access technology for sending the first data packet is the LTE technology. Implementation method e. For some V2X services, LTE, V2X, SL have priority; for other V2X services, NR, V2X, SL, etc. In a possible implementation, the first communication device may first obtain V2X from the core network or base station or locally The RAT V2X SL priority configuration corresponding to the service. Implementation method f, if the first communication device determines that the measurement result of LTE V2X SL is close to the measurement result of NR V2X SL, for example, the first communication device determines that the CBR corresponding to LTE V2X SL does not meet the first threshold, and the corresponding value of NR V2X SL The CBR meets the second threshold and can determine the priority of the first service to which the first data packet belongs.
本申请中,第一通信装置获取的辅助信息可以是通过检测V2X SL的质量信息,例如测量LTE V2X SL和NR V2X SL的CBR或者基于其他参考信号获得测量结果,例如基于 信道状态信息(channel state information,CSI)参考信号或者同步信道块(synchronization signal block,SSB)进行测量获得的测量结果。也可以是第一通信装置根据预设的规则定义不同V2X业务的优先级。In this application, the auxiliary information acquired by the first communication device may be by detecting the quality information of V2X SL, for example, measuring the CBR of LTE V2X SL and NR V2X SL, or obtaining measurement results based on other reference signals, for example, based on channel state information (channel state information, CSI) reference signal or synchronization channel block (synchronization signal block, SSB) measurement results obtained by measurement. It may also be that the first communication device defines priorities of different V2X services according to preset rules.
步骤202,第一通信装置根据第一无线接入技术,确定第一数据包对应的第一QoS参数。Step 202: The first communication device determines the first QoS parameter corresponding to the first data packet according to the first wireless access technology.
在一种可能的实现方式中,不同RAT SL可以有不同的指定QoS的机制,可使得QoS参数在不同的无线接入技术下是不同的。示例性地,若第一无线接入技术为LTE技术,则第一通信装置确定第一数据包对应的第一QoS参数为PPPP和/或PPPR;若第一无线接入技术为NR技术,则第一通信装置确定第一数据包对应的第一QoS参数为QFI和/或5QI。In a possible implementation manner, different RAT SLs may have different mechanisms for specifying QoS, which may make QoS parameters different under different wireless access technologies. Exemplarily, if the first wireless access technology is LTE technology, the first communication device determines that the first QoS parameter corresponding to the first data packet is PPPP and/or PPPR; if the first wireless access technology is NR technology, then The first communication device determines that the first QoS parameter corresponding to the first data packet is QFI and/or 5QI.
可选的,第一通信装置可确定第一数据包所属的第一业务对应的通信类型,根据第一无线接入技术和通信类型,确定第一QoS参数,通信类型包括广播、组播、或单播。在一种可能的实现方式中,若第一无线接入技术为NR技术、且通信类型为单播或组播,则第一通信装置确定第一QoS参数为QFI,若第一无线接入技术为NR技术、且通信类型为广播,则第一通信装置确定第一QoS参数为5QI。如此,对于通信类型为单播或者组播时,通信过程中的第一通信装置能够通过在先的配置交互获知QFI对应的QoS要求具体是什么,因此,可使用通过QFI标识第一QoS参数,有助于减小第一通信装置数据的传输量。而针对广播业务,不存在通信双方的协商,因此发送端的通信装置在发送数据时携带5QI信息,接收端通信装置可以通过5QI直接获知对应的QoS要求,而不需要依赖于在先的协商。Optionally, the first communication device may determine the communication type corresponding to the first service to which the first data packet belongs, and determine the first QoS parameter according to the first wireless access technology and the communication type. The communication type includes broadcast, multicast, or Unicast. In a possible implementation, if the first wireless access technology is NR technology and the communication type is unicast or multicast, the first communication device determines that the first QoS parameter is QFI, if the first wireless access technology If it is NR technology and the communication type is broadcast, the first communication device determines that the first QoS parameter is 5QI. In this way, when the communication type is unicast or multicast, the first communication device in the communication process can learn the specific QoS requirements corresponding to QFI through the previous configuration interaction. Therefore, the first QoS parameter can be identified by QFI, This helps reduce the amount of data transmitted by the first communication device. For the broadcast service, there is no negotiation between the two parties of communication. Therefore, the communication device at the sending end carries 5QI information when sending data, and the communication device at the receiving end can directly learn the corresponding QoS requirements through the 5QI without relying on prior negotiation.
步骤203,第一通信装置根据第一QoS参数,通过应用第一无线接入技术的第一无线直连通信接口向第二通信装置发送第一数据包。Step 203: The first communication device sends the first data packet to the second communication device according to the first QoS parameter through the first wireless direct communication interface to which the first wireless access technology is applied.
比如,若第一通信装置确定出第一QoS参数为PPPP和/或PPPR,则第一通信装置根据PPPP和/或PPPR,通过应用LTE的无线直连通信接口向第二通信装置发送第一数据包。For example, if the first communication device determines that the first QoS parameter is PPPP and/or PPPR, the first communication device sends the first data to the second communication device through the wireless direct communication interface using LTE according to PPPP and/or PPPR package.
再比如,若第一通信装置确定出第一QoS参数为QFI和/或5QI,则第一通信装置根据QFI和/或5QI,通过应用NR的无线直连通信接口向第二通信装置发送第一数据包。For another example, if the first communication device determines that the first QoS parameter is QFI and/or 5QI, the first communication device sends the first to the second communication device through the wireless direct communication interface using NR according to the QFI and/or 5QI data pack.
需要说明的是,在本申请中第一通信装置向第二通信装置发送第一数据包并不限定第一通信装置和第二通信装置之间存在连接,即第一通信装置可以是以广播,或者单播,或者组播的方式发送数据。针对广播的通信方式,第一通信装置以广播的方式发送数据,此时接收的通信装置可以是对数据所属的V2X业务或V2X业务类型感兴趣的任意第二通信装置。It should be noted that in this application, the first communication device sends the first data packet to the second communication device does not limit the existence of a connection between the first communication device and the second communication device, that is, the first communication device may be broadcast, Send data in either unicast or multicast. For the broadcast communication method, the first communication device sends data in a broadcast manner, and the received communication device at this time may be any second communication device that is interested in the V2X service or V2X service type to which the data belongs.
从上述步骤201至步骤203可以看出,第一通信装置具有两个通过应用无线接入技术的无线直连通信接口进行数据传输的能力,当确定使用第一无线直连通信接口发送第一数据包时,可确定出第一数据包对应的第一QoS参数,第一无线直连通信接口能识别出第一QoS参数。如此,在使用第一无线接入技术的第一无线直连通信接口发送第一数据包时,可不更改现有确定QoS参数的机制,按需确定出第一无线直连通信接口能识别的第一QoS参数。It can be seen from the above steps 201 to 203 that the first communication device has two data transmission capabilities through a wireless direct communication interface applying wireless access technology, and when it is determined that the first wireless direct communication interface is used to send the first data During the packet, the first QoS parameter corresponding to the first data packet can be determined, and the first wireless direct communication interface can recognize the first QoS parameter. In this way, when the first wireless direct communication interface using the first wireless access technology sends the first data packet, the existing mechanism for determining QoS parameters can be changed, and the first wireless direct communication interface can identify the first A QoS parameter.
在一种可能的场景中,第一通信装置当前所处的蜂窝网络为第二无线接入技术的蜂窝网络,即第一通信装置当前连接的核心网为第二无线接入技术的核心网,但第一通信装置选择应用第一无线接入技术的第一无线直连通信接口向第二通信装置发送第一数据包。例如,若第一通信装置当前所处的蜂窝网络为NR网络(即在5G系统中),连接的核心网为NR的核心网,即第五代核心网(5 th generation core,5GC),但第一通信装置选择用LTE V2X  SL进行通信。或者,若第一通信装置当前所处的蜂窝网络为LTE网络(即4G系统中),连接的核心网为LTE的核心网,即演进型分组核心网(evolved packet core,EPC),但是第一通信装置选择用NR V2X SL进行通信。针对该场景,图3为本申请提供的另一种通信方法流程示意图。如图3所示,该方法包括以下步骤: In a possible scenario, the cellular network where the first communication device is currently located is a cellular network of the second wireless access technology, that is, the core network currently connected to the first communication device is the core network of the second wireless access technology, However, the first communication device selects the first wireless direct communication interface applying the first wireless access technology to send the first data packet to the second communication device. For example, if the first communication device is currently located is NR cellular network (i.e., system 5G), NR a core network connected to a core network, i.e., the fifth-generation core network (5 th generation core, 5GC) , but The first communication device selects LTE V2X SL for communication. Or, if the cellular network where the first communication device is currently is an LTE network (that is, in a 4G system), the connected core network is an LTE core network, that is, an evolved packet core (EPC), but the first The communication device selects NR V2X SL for communication. For this scenario, FIG. 3 is a schematic flowchart of another communication method provided by this application. As shown in Figure 3, the method includes the following steps:
步骤301,第一通信装置确定第一数据包对应的第二QoS参数。Step 301: The first communication device determines the second QoS parameter corresponding to the first data packet.
示例性的,第一通信装置可根据第一通信装置当前所处蜂窝网络的无线接入技术,确定第一数据包对应的第二QoS参数。示例性地,若第一通信装置当前所处蜂窝网络为NR网络,连接的核心网为5GC,则可确定第一数据包对应的第二QoS参数为QFI和/或5QI。若第一通信装置当前所处的蜂窝网络为LTE网络,即连接的核心网为EPC,则可确定第一数据包对应的第二QoS参数为PPPP和/或PPPR。也可以理解为,第一通信装置当前所处蜂窝网络为NR网络,第一通信装置可默认映射出QFI和/或5QI;第一通信装置当前所处蜂窝网络为LTE网络,第一通信装置可默认映射出PPPP和/或PPPR。Exemplarily, the first communication device may determine the second QoS parameter corresponding to the first data packet according to the wireless access technology of the cellular network where the first communication device is currently located. Exemplarily, if the cellular network where the first communication device is currently is an NR network and the connected core network is 5GC, it may be determined that the second QoS parameter corresponding to the first data packet is QFI and/or 5QI. If the cellular network where the first communication device is currently located is an LTE network, that is, the connected core network is EPC, it may be determined that the second QoS parameter corresponding to the first data packet is PPPP and/or PPPR. It can also be understood that the cellular network where the first communications device is currently located is an NR network, and the first communications device may map QFI and/or 5QI by default; the cellular network where the first communications device is currently located is an LTE network, and the first communications device may By default, PPPP and/or PPPR are mapped.
步骤302,第一通信装置获取第一QoS参数和第二QoS参数之间的映射关系。Step 302: The first communication device obtains the mapping relationship between the first QoS parameter and the second QoS parameter.
示例性的,第一QoS参数和第二QoS参数之间的映射关系可以是第一通信装置从基站获取的,也可以是从核心网的V2X控制功能(control function,CF)节点中获取的,或者也可以是第一通信装置自己配置的。一种可能的实现方式中,第一通信装置可以根据协议规定的预设规则配置第一QoS参数和第二QoS参数之间的映射关系。Exemplarily, the mapping relationship between the first QoS parameter and the second QoS parameter may be obtained by the first communication device from the base station, or may be obtained from a V2X control function (CF) node of the core network, Or it may be configured by the first communication device itself. In a possible implementation manner, the first communication device may configure the mapping relationship between the first QoS parameter and the second QoS parameter according to a preset rule specified in the protocol.
上述步骤301和步骤302之间没有先后顺序,可以先执行步骤301,再执行步骤302;也可以先执行步骤301,后执行步骤302;或者步骤301和步骤302一起执行。There is no sequence between step 301 and step 302. Step 301 can be executed before step 302; step 301 can be executed first, and then step 302 can be executed; or step 301 and step 302 can be executed together.
步骤303,第一通信装置根据第二QoS参数和映射关系,确定第一数据包对应的第一QoS参数。Step 303: The first communication device determines the first QoS parameter corresponding to the first data packet according to the second QoS parameter and the mapping relationship.
示例性的,第一QoS参数对应第一无线接入技术。Exemplarily, the first QoS parameter corresponds to the first radio access technology.
在一种可能的实现方式中,若第一通信装置确定第二QoS参数为QFI和/或5QI,第一通信装置根据QFI和/或5QI与PPPP和/或PPPR之间的映射关系,映射出第一数据包对应的PPPP和/或PPPR。若第一通信装置确定第二QoS参数为PPPP和/或PPPR,第一通信装置根据QFI和/或5QI与PPPP和/或PPPR之间的映射关系,映射出第一数据包对应的QFI和/或5QI。In a possible implementation, if the first communication device determines that the second QoS parameter is QFI and/or 5QI, the first communication device maps out according to the mapping relationship between QFI and/or 5QI and PPPP and/or PPPR PPPP and/or PPPR corresponding to the first data packet. If the first communication device determines that the second QoS parameter is PPPP and/or PPPR, the first communication device maps the QFI and/or corresponding to the first data packet according to the mapping relationship between QFI and/or 5QI and PPPP and/or PPPR Or 5QI.
在一种可能的实现方式中,第一通信装置确定用于发送第一数据包的第一无线接入技术,根据第二QoS参数、映射关系和第一无线接入技术,确定第一QoS参数,第一无线接入技术对应第一QoS参数。可选地,第一通信装置确定用于发送第一数据包的第一无线接入技术可参见上述图2中步骤201中的实现方式一和实现方式二的介绍,此处不再赘述。In a possible implementation manner, the first communication device determines the first wireless access technology for sending the first data packet, and determines the first QoS parameter according to the second QoS parameter, the mapping relationship, and the first wireless access technology , The first radio access technology corresponds to the first QoS parameter. Optionally, the first communication device determines the first wireless access technology used to send the first data packet. For details, reference may be made to the introduction of implementation manner 1 and implementation manner 2 in step 201 in FIG. 2 above, and details are not described herein again.
步骤304,第一通信装置根据第一QoS参数,通过应用第一无线接入技术的第一无线直连接口向第二通信装置发送第一数据包。Step 304: The first communication device sends the first data packet to the second communication device through the first wireless direct connection port applying the first wireless access technology according to the first QoS parameter.
该步骤可参见上述图2中的步骤203的介绍,此处不再赘述。For this step, please refer to the introduction of step 203 in FIG. 2 above, which will not be repeated here.
从上述步骤301至步骤304可以看出,确定出第一数据包的第二QoS参数,在确定第一通信装置使用第一无线接入技术的第一无线直连接口发送第一数据包时,又因为第一无线接入技术与第一QoS参数对应,通过第一QoS参数和第二QoS参数之间的映射关系,可将第二QoS参数映射为第一QoS参数,从而实现第一通信装置根据第一QoS通过应用第一无线接入技术的第一无线直连接口向第二通信装置发送第一数据包。It can be seen from the above steps 301 to 304 that the second QoS parameter of the first data packet is determined, and when it is determined that the first communication device uses the first wireless direct connection port of the first wireless access technology to send the first data packet, Because the first wireless access technology corresponds to the first QoS parameter, the second QoS parameter can be mapped to the first QoS parameter through the mapping relationship between the first QoS parameter and the second QoS parameter, thereby implementing the first communication device The first data packet is sent to the second communication device according to the first QoS through the first wireless direct connection port applying the first wireless access technology.

该步骤可参见上述图2中的步骤203的介绍,此处不再赘述。For this step, please refer to the introduction of step 203 in FIG. 2 above, which will not be repeated here.
从上述步骤401至步骤403可以看出,第一通信装置可先确定出通过应用不同无线接入技术的无线直连通信接口发送第一数据包分别对应的QoS参数,之后从不同的QoS参数中选择出第一QoS参数,如此,第一通信装置可根据实际需要灵活的选择出所需的第一QoS参数。As can be seen from the above steps 401 to 403, the first communication device may first determine the QoS parameters corresponding to the first data packet sent by the wireless direct communication interface applying different wireless access technologies, and then select from the different QoS parameters The first QoS parameter is selected, so that the first communication device can flexibly select the required first QoS parameter according to actual needs.

For example, optical fiber, twisted pair, wireless access technology and other transmission media can be used for connection. In a possible implementation manner, the second layer 502 may include a Uu port access layer (Access Stratum, AS) 502a, an LTE V2X access layer 502b, and an NR V2X access layer 502c. The access layer 502a of the Uu port is used to receive information from the network device, for example, receive resource information and/or configuration information allocated by the network device for the first communication device. Exemplarily, the access layer 502a of the Uu port may be a radio resource control (Radio Resourcce Control, RRC) layer of the Uu port. The access layer 502b of LTE V2X is used to receive PPPP and/or PPPR from the transmission of the first layer 501; the access layer 502c of NR V2X is used to receive 5QI and/or QFI from the first layer 501.

Case 1: When the first layer of the first communication device sends the first data packet to the access layer 502b of LTE V2X, the QoS parameters carried are PPPP and/or PPPR. Case 2: When the first layer of the first communication device sends the first data packet to the NR V2X access layer 502c, the QoS parameters carried are QFI and/or 5QI. Case 3: When the first layer 501 of the first communication device sends the first data packet to the second layer 502, the QoS parameters carried include PPPP and/or PPPR, and QFI and/or 5QI. Case three may also be: when the first layer of the first communication device sends the first data packet to the access layer 502c of NR V2X, the QoS parameters carried are QFI and/or 5QI, and, PPPP and/or PPPR, to LTE When the access layer 502b of the V2X sends the first data packet, the QoS parameters carried are QFI and/or 5QI, and, PPPP and/or PPPR. The third situation is that the first layer 501 of the first communication device cannot recognize the LTE V2X access layer 502b and the NR V2X access layer 502c in the second layer 502.

For the second scenario above, the access layer 502c of the NR V2X of the first communication device sends the first data packet to the second communication device through the wireless direct communication interface using NR according to the received QFI and/or 5QI. For the third scenario above, if the LTE V2X access layer 502b of the first communication device determines that the first data packet corresponds to LTE V2X, the NR V2X access layer 502c of the first communication device discards the first data packet, and the first According to the received PPPP and/or PPPR, the access layer 502b of the LTE V2X of the communication device sends the first data packet to the second communication device through the wireless direct communication interface applying LTE; if the NR of the first communication device connects to V2X When the incoming layer 502c determines that the first data packet corresponds to NR V2X, the LTE V2X access layer 502b of the first communication device discards the first data packet, and the NR V2X access layer 502c of the first communication device according to the received QFI and /Or 5QI, sending the first data packet to the second communication device through the wireless direct communication interface using NR.

Accordingly, the first layer of the first communication device receives the instruction information from the second layer of the first communication device. In another possible implementation manner, the indication information may also be sent by the CF node of the core network to the first layer of the first communication device. In another possible implementation manner, the indication information may also be configured by the first layer of the first communication device according to a protocol preset rule.

实现方式一,第一通信装置的第一层根据指示信息,确定用于发送第一数据包的第一无线接入技术。In a first implementation manner, the first layer of the first communication device determines the first wireless access technology for sending the first data packet according to the instruction information.
第一通信装置的第一层从第一通信装置的第二层接收指示信息,第一通信装置的第一层根据指示信息,确定用于发送第一数据包的第一无线接入技术,第一数据包属于第一业务,指示信息用于指示第一业务对应的第一无线接入技术。通过在第一通信装置的第二层向第一通信装置的第一层发送指示信息,可以使得第一通信装置的第一层确定出第一通信装置发送第一数据包的第一无线接入技术对应的第一无线直连通信接口,从而第一通信装置的第二层根据第一无线接入技术,确定出第一通信装置的第一层可以识别的第一QoS参数。The first layer of the first communication device receives the instruction information from the second layer of the first communication device, and the first layer of the first communication device determines the first wireless access technology for transmitting the first data packet according to the instruction information, the first A data packet belongs to the first service, and the indication information is used to indicate the first wireless access technology corresponding to the first service.

该实施例中,指示信息可以参见上述图2的步骤201的实现方式一中指示信息的介绍,此处不再赘述。In this embodiment, for the indication information, refer to the introduction of the indication information in the first implementation manner of step 201 in FIG. 2 described above, and details are not described herein again.
实现方式二,第一通信装置的第一层根据辅助信息,确定用于发送第一数据包的第一无线接入技术。Implementation manner 2: The first layer of the first communication device determines the first wireless access technology used to send the first data packet according to the auxiliary information.
示例性的,辅助信息可以包括以下至少一种:不同无线接入技术的无线直连通信接口分别对应的信道忙碌率(channel bussy ratio,CBR)、不同无线接入技术的无线直连通信接口分别对应的优先级、覆盖第一通信装置的当前小区支持的无线接入技术的无线直连通信接口;示例性的,第一无线接入技术为无线接入技术中的任一种。Exemplarily, the auxiliary information may include at least one of the following: a channel busy rate (CBR) corresponding to wireless direct connection communication interfaces of different wireless access technologies, and wireless direct connection communication interfaces of different wireless access technologies respectively Corresponding priority, a wireless direct communication interface covering the wireless access technology supported by the current cell of the first communication device; exemplarily, the first wireless access technology is any one of the wireless access technologies.
本申请中,可以是第一通信装置的第二层获取辅助信息,第一通信装置的第二层将获取到的辅助信息向第一通信装置的第一层发送,第一通信装置的第一层再根据第二层发送的辅助信息确定用于发送第一数据包的第一无线接入技术。通过第一通信装置的第二层向第一通信装置的第一层发送辅助信息,可以使得第一通信装置的第一层确定出的无线接入技术更符合真实的环境。In this application, it may be that the second layer of the first communication device obtains auxiliary information, and the second layer of the first communication device sends the obtained auxiliary information to the first layer of the first communication device. The layer determines the first wireless access technology for sending the first data packet according to the auxiliary information sent by the second layer. Sending auxiliary information to the first layer of the first communication device through the second layer of the first communication device can make the wireless access technology determined by the first layer of the first communication device more in line with the real environment.
该实施例中辅助信息的详细介绍可参见上述图2的步骤201中的实现方式二,此处不再赘述。For a detailed introduction of auxiliary information in this embodiment, reference may be made to the second implementation manner in step 201 of FIG. 2 above, and details are not described herein again.
步骤602,第一通信装置的第一层根据第一无线接入技术,确定第一数据包对应的第一QoS参数。Step 602: The first layer of the first communication device determines the first QoS parameter corresponding to the first data packet according to the first wireless access technology.
在一种可能的实现方式中,若第一无线接入技术为LTE技术,则第一通信装置的第一层确定第一数据包对应的第一QoS参数为PPPP和/或PPPR;若第一无线接入技术为新空口NR技术,则第一通信装置的第一层确定第一数据包对应的第一QoS参数为QFI和/或5QI。In a possible implementation, if the first wireless access technology is LTE technology, the first layer of the first communication device determines that the first QoS parameter corresponding to the first data packet is PPPP and/or PPPR; if the first The wireless access technology is the new air interface NR technology, and the first layer of the first communication device determines that the first QoS parameter corresponding to the first data packet is QFI and/or 5QI.
可选的,第一通信装置的第一层可确定第一数据包所属的第一业务对应的通信类型,通信类型包括广播、组播、或单播。在一种可能的实施方式中,若第一无线接入技术为NR技术、且通信类型为单播或组播,则第一通信装置的第一层确定第一QoS参数为QFI。若第一无线接入技术为NR技术、且通信类型为广播,则第一通信装置的第一层确定第一QoS参数为5QI。如此,对于通信类型为单播或者组播时,通信过程中的第一通信装置能够通 过在先的配置交互获知QFI对应的QoS要求具体是什么,因此,可使用通过QFI标识第一QoS参数,有助于减小第一通信装置数据的传输量。而针对广播业务,不存在通信双方的协商,因此发送端的通信装置在发送数据时携带5QI信息,接收端通信装置可以通过5QI直接获知对应的QoS要求,而不需要依赖于在先的协商。Optionally, the first layer of the first communication device may determine the communication type corresponding to the first service to which the first data packet belongs, and the communication type includes broadcast, multicast, or unicast. In a possible implementation manner, if the first wireless access technology is the NR technology and the communication type is unicast or multicast, the first layer of the first communication device determines that the first QoS parameter is QFI. If the first radio access technology is NR technology and the communication type is broadcast, the first layer of the first communication device determines that the first QoS parameter is 5QI. In this way, when the communication type is unicast or multicast, the first communication device in the communication process can learn the specific QoS requirements corresponding to QFI through the previous configuration interaction. Therefore, the first QoS parameter can be identified by QFI, This helps reduce the amount of data transmitted by the first communication device. For the broadcast service, there is no negotiation between the two parties of communication. Therefore, the communication device at the sending end carries 5QI information when sending data, and the communication device at the receiving end can directly learn the corresponding QoS requirements through the 5QI without relying on prior negotiation.
步骤603,第一通信装置的第二层根据第一QoS参数,通过应用第一无线接入技术的第一无线直连通信接口向第二通信装置发送第一数据包。Step 603: The second layer of the first communication device sends the first data packet to the second communication device through the first wireless direct connection communication interface applying the first wireless access technology according to the first QoS parameter.
该步骤可参见上述图2中的步骤203的介绍,此处不再赘述。For this step, please refer to the introduction of step 203 in FIG. 2 above, which will not be repeated here.
从上述步骤601至步骤603可以看出,第一通信装置具有两个通过应用无线接入技术的无线直连通信接口进行数据传输的能力,第一通信装置的第二层在确定使用第一无线直连通信接口发送第一数据包时,通知第一通信装置的第一层,可使得第一通信装置的第一层确定出第一数据包对应的第一QoS参数,第一通信装置的第一层向第一通信装置的第二层发送第一QoS参数,第一通信装置的第二层根据第一QoS参数发送第一数据包。即第一通信装置的第二层在使用第一无线接入技术的第一无线直连通信接口发送第一数据包时,通过第一通信装置的第一层和第二层之间的交互,可实现不改变现有的LTE V2X系统中的QoS参数管理机制,按需确定出第一无线直连通信接口能识别的第一QoS参数。It can be seen from the above steps 601 to 603 that the first communication device has two data transmission capabilities through a wireless direct communication interface applying wireless access technology, and the second layer of the first communication device is determining to use the first wireless When the directly connected communication interface sends the first data packet, the first layer of the first communication device is notified, so that the first layer of the first communication device determines the first QoS parameter corresponding to the first data packet, and the first The first layer sends the first QoS parameter to the second layer of the first communication device, and the second layer of the first communication device sends the first data packet according to the first QoS parameter. That is, the second layer of the first communication device uses the interaction between the first layer and the second layer of the first communication device when sending the first data packet using the first wireless direct communication interface of the first wireless access technology, The first QoS parameter recognized by the first wireless direct connection communication interface can be determined as needed without changing the existing QoS parameter management mechanism in the LTE V2X system.

Exemplarily, it may be that the second layer of the first communication device determines the wireless access technology corresponding to the first service of the first data packet, and if it is the first wireless access technology, the second layer of the first communication device Among the QoS parameters, the first QoS parameter corresponding to the first wireless access technology is selected. Exemplarily, the first layer of the first communication device may send the first QoS parameter and the second QoS parameter to the second layer of the first communication device, and the second layer of the first communication device determines that the first data corresponds to the first For wireless access technology, the first QoS parameter is used to send the first data packet on the first wireless direct connection port of the first wireless access technology. In a possible implementation manner, the second layer of the first communication device determines the radio access technology corresponding to the first service. Refer to the introduction of implementation manner 1 in step 201 of FIG. 2 above, and details are not described herein again. The second layer of the first communication device may also determine the wireless access technology corresponding to the first service through the indication information of the wireless access technology carried by the first layer, that is, at this time, the first layer sends the first data to the second layer The packet also includes the corresponding first QoS parameter, second QoS parameter and indication information of the radio access technology. The second layer of the first communication device determines the wireless access technology of the first data packet according to the indication information of the wireless access technology, and then determines the application of the first QoS parameter or the second QoS parameter. Specifically, if the first data packet corresponds to the wireless The access technology is the first wireless access technology, and the second layer applies the first QoS parameters for data transmission. If the wireless access technology corresponding to the second data packet is the second wireless access technology, the second layer applies the second QoS parameters for data transmission.
结合上述图5中的情形三,以第一QoS参数为PPPP和/或PPPR,第二QoS参数为QFI和/或5QI为例说明。第一通信装置的第一层向LTE V2X的接入层502b发送PPPP和/或PPPR,向NR V2X的接入层502c发送QFI和/或5QI。在LTE V2X的接入层502b和NR V2X的接入层502c均接收到第一数据包后,LTE V2X的接入层502b和NR V2X的接入层502c分别确定第一数据包对应的无线接入技术,第一数据包对应的无线接入技术可以是通过第一层指示的,即第一层向LTE V2X的接入层502b和NR V2X的接入层502c发送第一数据包时,还可以指示第一数据包对应的无线接入技术。若确定的第一数据包对应的无线接入技术与接入层的无线接入技术不同时,不发送第一数据包;若确定第一数据包对应的无线接入类型与接入层的无线接入类型相同时,通过应用第一无线直连接口发送第一数据包。比如若LTE V2X的接入层502b确定第一数据包对应的无线接入类型是LTE时,则通过应用LTE无线直连接口发送第一数据包,若LTE V2X的接入层502b确定第一数据包对应的无线接入类型不是LTE时,则不发送第一数据包。再比如,若NR V2X的接入层502c确定第一数据包对应的无线接入类型是NR时,通过应用NR无线直连接口发送第一数据包,若NR V2X的接入层502c确定第一数据包对应的无线接入类型不是NR时,则不发送第一数据包。可选地,LTE V2X的接入层502b和NR V2X的接入层502c分别确定第一数据包对应的无线接入技术的实现方式可参见上述图2的步骤201中实现方式一的介绍,此处不再赘述。With reference to the third scenario in FIG. 5 above, the first QoS parameter is PPPP and/or PPPR, and the second QoS parameter is QFI and/or 5QI as an example. The first layer of the first communication device sends PPPP and/or PPPR to the LTE V2X access layer 502b, and sends QFI and/or 5QI to the NR V2X access layer 502c. After the LTE V2X access layer 502b and the NR V2X access layer 502c both receive the first data packet, the LTE V2X access layer 502b and the NR V2X access layer 502c respectively determine the wireless connection corresponding to the first data packet Technology, the wireless access technology corresponding to the first data packet may be indicated through the first layer, that is, when the first layer sends the first data packet to the LTE V2X access layer 502b and the NR V2X access layer 502c, the The wireless access technology corresponding to the first data packet may be indicated. If the determined radio access technology corresponding to the first data packet is different from the radio access technology of the access layer, the first data packet is not sent; if the radio access type corresponding to the first data packet is determined and the radio of the access layer When the access types are the same, the first data packet is sent by applying the first wireless direct connection port. For example, if the access layer 502b of LTE V2X determines that the wireless access type corresponding to the first data packet is LTE, the first data packet is sent by applying the LTE wireless direct connection port, and if the access layer 502b of LTE V2X determines the first data When the wireless access type corresponding to the packet is not LTE, the first data packet is not sent. For another example, if the access layer 502c of NR V2X determines that the wireless access type corresponding to the first data packet is NR, the first data packet is sent by applying the NR wireless direct connection port, and if the access layer 502c of NR V2X determines the first When the wireless access type corresponding to the data packet is not NR, the first data packet is not sent. Optionally, the implementation layer of the LTE V2X access layer 502b and the NR V2X access layer 502c respectively determine the wireless access technology corresponding to the first data packet. Refer to the introduction of the implementation mode 1 in step 201 of FIG. 2 above. I will not repeat them here.
示例性的,第一层501从第三层503接收到第一数据包之后的处理可以是把第一数据包分别发送给LTE V2X的接入层502b和NR V2X的接入层502c,且发给LTE V2X的接入层502b时,需要携带PPPP和/或PPPR;发给NR V2X的接入层502c时,需要携带QFI和/或5QI,可选的,向LTE V2X的接入层502b和NR V2X的接入层502c发送第一数据包时,还可以指示第一数据包对应的无线接入技术。第一层501从第三层503接收到第一数据包之后的处理还可以是把第一数据包发给第二层502,在发给第二层502时,同时携带PPPP和/或PPPR,以及,QFI和/或5QI,可选的,第一层501向第二层502发送第一数据包时,还可以指示第一数据包对应的无线接入技术。两种方式的区别在于第一层501是否能识别出第二层502中的LTE V2X的接入层502b和NR V2X的接入层502c。如果可以,则第一层501可以分别向LTE V2X的接入层502b和NR V2X的接入层502c发送第一数据包及携带的对应的QoS参数,隐含地是要求第一层501对第一数据包执行复制操作。如果不可以,则第一层501可向第二层502发送第一数据包,以及不同的QoS参数。Exemplarily, the processing after the first layer 501 receives the first data packet from the third layer 503 may be to send the first data packet to the access layer 502b of LTE V2X and the access layer 502c of NR V2X, and send For LTE V2X access layer 502b, PPPP and/or PPPR need to be carried; for NR V2X access layer 502c, it needs to carry QFI and/or 5QI, optionally, to LTE V2X access layer 502b and When the access layer 502c of NR V2X sends the first data packet, it may also indicate the wireless access technology corresponding to the first data packet. After the first layer 501 receives the first data packet from the third layer 503, the processing may be that the first data packet is sent to the second layer 502, and when sent to the second layer 502, it also carries PPPP and/or PPPR, And, QFI and/or 5QI, optionally, when the first layer 501 sends the first data packet to the second layer 502, it may also indicate the radio access technology corresponding to the first data packet. The difference between the two methods is whether the first layer 501 can recognize the LTE V2X access layer 502b and the NR V2X access layer 502c in the second layer 502. If possible, the first layer 501 can send the first data packet and the corresponding QoS parameters carried to the access layer 502b of LTE V2X and the access layer 502c of NR V2X, implicitly One packet performs the copy operation. If it is not possible, the first layer 501 may send the first data packet to the second layer 502, as well as different QoS parameters.
在第二种实现方式中,第一通信装置的第二层确定第一业务对应的无线接入技术为第一无线接入技术的实现方式可参见上述图6中的步骤601的过程,在此不再赘述。In the second implementation, the second layer of the first communication device determines that the radio access technology corresponding to the first service is the implementation of the first radio access technology.

示例性的,可以是第一通信装置的第二层根据第一QoS参数,通过应用第一无线接入技术的第一无线直连通信接口向第二通信装置发送第一数据包。Exemplarily, it may be that the second layer of the first communication device sends the first data packet to the second communication device through the first wireless direct communication interface applying the first wireless access technology according to the first QoS parameter.

Moreover, it can help to reduce the number of interlayer interactions between the first layer of the first communication device and the second layer of the first communication device, which helps to simplify the implementation of the first communication device.

相应地,AS层从V2X层接收不同的QoS参数和第一数据包。Accordingly, the AS layer receives different QoS parameters and the first data packet from the V2X layer.
步骤1405,AS层从不同的QoS参数中选择出第一QoS参数。Step 1405, the AS layer selects the first QoS parameter from different QoS parameters.
