由于通过PC5接口进行通信的PC5通信模式支持网络覆盖和无网络覆盖，因此V2X中设备之间通信通常所采用的通信模式为PC5通信模式。由于车联网中设备之间通信通常所采用的通信模式为PC5通信模式，因此现有的车联网空口资源调度方法主要针对PC5接口资源的调度。对PC5接口资源的调度分为有基站覆盖情况和无基站覆盖情况。在无基站覆盖的情况下，车联网中的设备可以利用全球导航卫星系统(global navigation satellite system，GNSS)进行时间同步，并通过在车车(vehicle to vehicle，V2V)间通信中采用分散型调度技术，实现V2V间通信的调度和接口管理；在有基站覆盖的情况下，则可用采用LTE系统中的无线基站对V2V间通信的调度和接口的管理进行辅助。
由于PC5通信模式为近距离通信，受制于PC5空口资源量的限制，即便是在基站参与调度的情况下，在能够通过PC5通信模式进行通信的范围内，可允许接入的V2X网络的终端设备的最大接入数量为也非常有限。在城市比较繁忙或拥堵的十字路口，采用PC5接口进行通信可能会因为PC5空口资源量有限而导致V2V间通信出现资源拥堵、带宽不够或信号质量下降等情况。

附图说明
为了更清楚地说明本申请的技术方案，下面将对实施例中所需要使用的附图作简单介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据 这些附图获得其他的附图。
图1为本申请通信系统一个实施例的结构示意图；
图2为本申请通信模式切换方法一个实施例的流程图；
图3为本申请通信模式切换方法另一个实施例的流程图；
图4为本申请通信模式切换方法再一个实施例的流程图；
图5为本申请网络侧设备一个实施例的结构示意图；
图6为本申请终端设备另一个实施例的结构示意图；
图7为本申请用于通信模式切换的设备一个实施例的结构示意图。
具体实施方式
参见图1，为本申请通信系统一个实施例的结构示意图。
如图1所示，所述通信系统可以是V2X通信系统，包括V2X控制功能(V2X control function)与PC5-Uu资源调度功能(PC5-Uu resource scheduling function)。其中，所述PC5Uu资源调度功能可以是所述V2X控制功能的一部分或者所述V2X控制功能本身，也可以独立于所述V2X控制功能之外。即，所述V2X控制功能可以位于同一个网络侧设备上，也可以位于不同的网络侧设备上。
具体实现中，当PC5Uu资源调度功能位于V2X控制功能时，则可以与eNodeB具有外部接口，并且与V2X控制功能中其他功能模块具有内部接口。所述PC5Uu资源调度功能也可位于eNodeB，当PC5Uu资源调度功能位于eNodeB时，则可以与V2X控制功能具有外部接口。所述PC5Uu资源调度功能也可位于通信系统中的其他网元，如果PC5Uu资源调度功能位于通信系统中的其他网元，则可以与eNodeB与V2X控制功能均有外部接口。
除所述车联网控制功能体和所述PC5Uu资源调度功能之外，所述通信系统还可以包括至少一个终端设备，所述终端设备可以是车辆等车联网终端设备，也可以其它移动终端，对此本申请不做限定。
所述终端设备之间至少可以通过第一通信模式或通过第二通信模式进行通信，第一通信模式和第二通信模式为不同的通信模式，二者使用不同的无线资源。通常情况下，所述第一通信模式与所述第二通信模式所使用接口不同。例如，如果所述第一通信模式为PC5通信模式，那么所述第二通信模式可以为Uu通信模式；如果所述第一通信模式为Uu通信模式，那么所述第二通信模式则可以为PC5通信模式。其中，Uu通信模式是指通过LTE Uu接口进行通信的通信模式，而PC5通信模式则是指通过PC5接口进行通信的通信模式。
参见图2，为本申请通信模式切换方法一个实施例的流程示意图。下面结合图2所示， 以所述PC5Uu资源调度功能独立于所述V2X控制功能之外为例对本申请进行说明。
步骤201，PC5-Uu资源调度功能在第一终端设备接入网络的过程中，向第一终端设备下发资源测量配置。
所述测量配置用于配置第一终端设备测量无线资源的测量方式。其中，所述无线资源为第一终端设备传输所述第一V2X业务可用的无线资源。所述测量配置中可以包含测量目标(measurement object)、测量时间(measurement period)、测量事件(measurement event)、门限参数(threshold parameter)等信息。所述测量配置中还可以包含上报周期或触发条件等用于指示终端设备需要在何种条件下上报测量报告的上报条件信息。
步骤202，第一终端设备在发起第一V2X业务时，根据测量配置进行测量。
如果第一终端设备需要发起第一V2X业务，并且需要采用第一传输模式传输所述第一V2X业务，那么第一终端设备可以按照所述测量配置对目标无线资源进行测量。其中，所述目标无线资源，是指被分配用于采用第一传输模式传输所述第一V2X业务的无线资源，或者可用于采用第一传输模式传输所述第一V2X业务的无线资源，简而言之，所述目标无线资源可以是指第一通信模式的无线资源。在实际使用中，所述目标无线资源可以是被分配用于采用第一传输模式传输包含所述第一V2X业务在内的多个业务的无线资源型；或者也可以是被分配用于采用第一传输模式传输第一终端设备的所有V2X业务的所用无线资源，对此本申请不做限定。通常来说，
根据应用场景及第一V2X业务的不同，所述目标无线资源的类型也不相同。通常情况下，所述目标无线资源可以是通过PC5接口进行数据传输所需的无线资源，也可以是通过Uu接口进行通信所需的无线资源，或者也可以采用其他接进行数据传输所需的无线资源。在V2X通信系统中，所述目标无线资源通常可以是用于采用PC5接口进数据传输所要使用的无线资源。
例如，如果第一V2X业务被预先设定采用PC5通信模式进行数据传输，那么第一终端设备在发起第一V2X业务时，可以按照所述测量配置对采用PC5通信模式进行数据传输所用的无线资源进行测量。
步骤203，第一终端设备向PC5-Uu资源调度功能上报测量报告。
第一终端设备可以根据目标无线资源的测量结果生成测量报告，然后将所述测量报告发送给PC5-Uu资源调度功能。第一终端设备可以在符合所述上报条件信息所指示的上报条件时，上报所述测量报告。例如，第一终端设备可以按照测量配置所配置的上报周期，周期性上报所述测量报告；或者在符合测量配置所述配置的触发条件时，上报所述测量报告。
当所述目标无线资源不能满足第一V2X业务的数据传输需求时，所述测量报告中可以包含事件指示信息。即，所述事件指示信息可以用于指示第一通信模式的无线资源不能满足所述第一终端采用第一通信模式传输所述第一V2X业务的传输需求。
目标无线资源不能满足所述第一终端采用第一通信模式传输第一V2X业务的数据传输需求可以包含多种情况，具体可以包括：没有可以用于采用第一通信模式传输第一V2X业务的无线资源；可用于采用第一通信模式传输第一V2X业务的无线资源的资源量过少或信号质量过差，导致不能满足第一V2X业务的传输需求等。
由于第一通信模式可能是PC5通信模式或Uu通信模式，因此所述目标无线资源可能是采用PC5通信模式传输所述第一V2X业务所需的无线资源或也可能是采用Uu通信模式传输所述第一V2X业务所需的无线资源。因此目标无线资源的不足既可能是通过PC5接口进行通信所需的无线资源也可能是通过Uu接口进行通信的无线资源不足，因此所述指示信息可以仅用于指示目标无线资源的不足，也可以在指示目标无线资源的不足的基础上进一步指示目标无线资源为哪一类无线资源。
所述时间指示信息的具体内容及其所标识的含义可以预先设定。例如，所述事件指示信息可以为事件P1(event P1)。在实际应用中，无论所述目标无线资源是采用PC5通信模式传输所述第一V2X业务所需的无线资源，还是采用Uu通信模式传输所述第一V2X业务所需的无线资源，均通过event P1指示所述目标无线资源的不足。或者，也可以通过event P1指示通过PC5接口传输第一V2X业务所需的无线资源不足，而通过其他事件指示信息指示通过Uu接口或其他接口传输第一V2X业务所需的无线资源不足。对此本申请不做限定。
除了所述事件指示信息之外，所述测量报告中还可以包含：第一终端设备的设备标识，第一V2X业务的业务标识(service ID)。由于业务标识唯一标识一个业务，而设备标识唯一标识一个终端设备，所述测量报告中包含第一终端设备的设备标识和第一V2X业务的业务标识，可以使PC5-Uu资源调度功能及通信系统中的其他设备或功能确定哪一个终端设备是所述第一终端设备，并确定哪一个业务是所述第一V2X业务。
例如，当第一终端设备的设备标识为Vehicle A，第一V2X业务的业务标识为12，第一V2X业务被预先设定采用PC5通信模式进行数据传输时，如果第一终端设备在发起第一V2X业务时，通过测量发现采用PC5通信模式进行第一V2X业务的数据传输所需的无线资源不足，那么就可以向PC5-Uu资源调度功能发送测量报告，所述测量报告中包含event P1，Vehicle A，12等信息。
步骤204，PC5-Uu资源调度功能根据所述测量报告，确定需要由第一通信模式切换为第二通信模式的第二V2X业务。
如果所述测量报告中包含指示信息，那么所述PC5-Uu资源调度功能就可以根据所述测量报告得知目标无线资源不足。在得知所述目标无线资源不足后，PC5-Uu资源调度功能可以根据预设的切换策略确定需要由第一通信模式切换为第二通信模式的第二V2X业务，以及第二V2X业务所属的第二终端设备。其中，所述切换策略可以由无线资源管理情况、V2X业务QoS、RSU部署情况等决定。
PC5-Uu资源调度功能可以根据终端设备的数据传输优先级，V2X业务的数据传输优先级， 或者V2X业务使用第一通信模式进行数据传输的优先级等信息，确定需要由第一通信模式切换为第二通信模式的第二V2X业务，以及第二V2X业务所属的第二终端设备。
例如，PC5-Uu资源调度功能可以从数据传输优先级低于所述第一终端设备的各个终端设备中选择一个作为所述第二终端设备，然后从第二设备的V2X业务中选择一个作为所述第二V2X业务。或者，PC5-Uu资源调度功能也可以直接将所述第一终端设备作为所述第二终端设备，然后从采用第一通信模式进行数据传输且优先级低于所述第一V2X业务的V2X业务中选择一个作为所述第二V2X业务。或者，所述PC5-Uu资源调度功能也可以直接将所述第一终端设备作为所述第二终端设备，并将所述第一V2X业务作为所述第二V2X业务。
在此需要说明的是，在本申请中，第二V2X业务与第一V2X业务可以是同一个业务，也可以是不同的业务。当第二V2X业务与第一V2X业务是不同的业务时，第二V2X业务与第一V2X业务可以是不同终端设备的业务，也可以是同一个终端设备的业务，即，所述第一V2X业务与所述第二V2X可以为第一终端设备的不同业务。
步骤205，PC5-Uu资源调度功能向V2X控制功能发送模式切换指示。
由于终端设备进行V2X业务传输所采用的通信模式由V2X控制功能进行授权调整，因此当PC5-Uu资源调度功能确定了所述第二终端设备及所述第二V2X业务后，可以向V2X控制功能发送模式切换指示(mode switch notify)。
所述mode switch notify可以用于指示V2X控制功能切换所述第二V2X业务的通信模式。通常情况下，所述模式切换指示可以用于指示V2X控制功能向第二终端设备发送第一更新授权参数，以通过第一更新授权参数调整所述第二V2X业务的通信模式。
为使V2X控制功能能够切换所述第二V2X业务的通信模式，所述模式切换指示可以包含：第二终端设备的设备标识,第二V2X业务的service ID，第一切换命令等信息。其中，第一切换命令用于指示将第二V2X业务的通信模式切换为第二通信模式，根据第二通信模式的不同所述第一切换命令的具体内容也可相应有所不同。
模式切换指示中所包含的信息可以使V2X控制功能得知哪一个终端设备为第二终端设备，哪一个业务为第二V2X业务，以及需要第二V2X业务的通信模式切换为哪种通信模式。第一切换命令可以仅用于指示将第二V2X业务的通信模式切换为哪种通信模式，而不用指示第二V2X业务的当前通信模式为何。例如，所述第一切换命令可以为PC5-Uu，具体用于指示将第二V2X业务的通信模式从PC5通信模式切换为Uu通信模式。或者，也可以为Uu-PC5具体用于指示将第二V2X业务的通信模式从Uu通信模式切换为PC5通信模式。或者，也可以为Uu，表示将第二V2X业务的通信模式从当前模式切换为Uu通信模式。
除所述第二终端设备设备标识，第二V2X业务的service ID，以及第一切换命令之外，所述模式切换指示中还可以包含：切换标识(switch ID)，所述切换标识可以用于指示本次模式切换的相关信息。例如，所述切换标识用于指示切换记录，所述切换记录用于记录第二V2X业务的业务标识与第一切换命令，以及检测时长、将第二V2X业务的通信模式从第一通 信模式切换为第二通信模式的切换时刻等。V2X控制功能及PC5-Uu资源调度功能均可以保存所述切换标识及与所述切换标识对应的切换记录。
所述切换标识可以相对于所述第二终端设备唯一，即，所述第二终端设备每进行一次V2X业务的通信模式切换都唯一对应一个切换标识。通过所述切换标识，PC5-Uu资源调度功能或V2X控制功能可以获取到第二V2X业务的service ID，以及第一切换命令等信息。所述切换标识可以相对于所述通信系统全局唯一，即在所述通信系统中，每个终端设备的每一次模式切换都唯一对应一个切换标识，当所述切换标识可以相对于所述通信系统全局唯一时，所述切换记录中还可以包含第二终端设备的设备标识以及第一终端设备的设备标识信息。通过所述切换标识，V2X控制功能及PC5-Uu资源调度功能可以获取到所述第二终端设备设备标识，第二V2X业务的service ID，以及第一切换命令等相关信息。
例如，如果第二终端设备的设备标识为Vehicle B，第二V2X业务的业务标识为11，第一切换命令为PC5-Uu，而本次模式切换的切换标识为switch 1，那么所述模式切换指示中可以包含Vehicle B，11，PC5-Uu及switch 1，或者也可以仅包含Vehicle B，11及PC5-Uu。
步骤206，V2X控制功能向第二终端设备发送第一更新授权参数。
V2X控制功能在接收到PC5-Uu资源调度功能发送的模式切换指示之后，可以根据模式切换指示确定第二终端设备及第二V2X业务，并生成第一更新授权参数；然后将第一更新授权参数发送给第二终端设备，从而使所述第二终端设备按照所述更新授权参数的指示，将第二V2X业务的通信模式切换为第二通信模式。其中，所述第一更新授权参数可以用于指示第二终端设备将所述第二V2X业务的通信模式由原通信模式切换为第二通信模式。
例如，V2X控制功能根据从所述模式切换指示中获取到的设备标识确定所述第二终端设备；根据从所述模式切换指示中获取到的业务标识确定所述第二V2X业务；根据从所述模式切换指示中获取到的第一切换命令确定所述第二通信模式。
以3GPP TS24.386所规定的授权参数格式为例，V2XoverPC5参数项下的AuthorizedV2XServiceList用于指示所有需要使用PC5通信模式进行传输的V2X业务；而V2XoverLTEUu参数项下的AuthorizedV2XServiceList则用于指示所有需要使用Uu通信模式进行传输的V2X业务。
因此如果第二V2X业务的service ID是11，并且预先为第二V2X业务分配的第一通信模式为PC5通信模式，那么在预先配置给第二终端设备的授权参数中，V2XoverPC5参数项下的AuthorizedV2XServiceList中会包含第二V2X业务的业务标识11；而V2XoverLTEUu参数项下的AuthorizedV2XServiceList中则不会包含第二V2X业务的业务标识11。
如果需要将第二V2X业务的通信模式切换为Uu通信模式，那么就需要通过第一更新授权参数删除V2XoverPC5参数项下的AuthorizedV2XServiceList中所包含第二V2X业务的业务标识11，并且在V2XoverLTEUu参数项下的AuthorizedV2XServiceList中添加第二V2X业务的业务标识11。
当所述模式切换指示中还包含切换标识时，所述V2X控制功能还可以保存所述切换标识与所述模式切换指示中包含的设备标识、务标识及第一切换命令的对应关系。即，所述V2X控制功能还可以保存所述模式切换指示与所述第二终端设备的设备标识，与所述第二V2X业务的业务标识，以及与所述第一切换命令之间的对应关系。
由于3GPP协议中规定由终端设备的上层应用决定V2X业务所采用的传输模式，但是终端设备上层应用却无法感知V2X业务实际被授权使用那种通信模式进行数据传输。因因此，将第二V2X业务的通信模式切换为第二通信模式后，第二终端设备就会再次为第二V2X业务发起业务授权过程。例如，如果第二终端设备应用层决定使用PC5模式传输第二V2X业务，但是如果第二V2X业务的传输模式被切换不为PC5传输模式的其他传输模式，那么会出现第二终端设备在传输第二V2X业务的过程中，会进行授权参数查询，并出现查询不到授权参数的情况。如果出现查询不到授权参数的情况，那么第二终端设备就会再次为第二V2X业务发起业务授权过程。
为避免第二终端设备再次为第二V2X业务发起业务授权，所述第一更新授权参数中还可以包含添加模式指示(ModeIndication)这一参数项，用于向终端设备的上层应用指示所述第二V2X业务的传输模式已经被切换为第二传输模式。在ModeIndication参数项中可以包含UuIndication和PC5Indication等指示信息，其中，UuIndication用于指示被切换为采用Uu通信模式进数据传输的业务，PC5Indication用于指示被切换为采用PC5通信模式进数据传输的业务。其中，ModeIndication参数项相比于V2XoverLTEUu参数项和V2XoverPC5参数项具有较高优先级。从而可以使第二终端设备的上层应用按照ModeIndication参数项的指示，调用与第二传输模式相对应的传输模块传输所述第二V2X业务的业务数据，而不再按照V2XoverLTEUu参数项或V2XoverPC5参数项的指示调用传输模块。
例如，如果将第二V2X业务的通信模式切换为PC5通信模式，那么UuIndication中可以包含第二V2X业务的业务标识11，而所述PC5Indication则不包含第二V2X业务的业务标识11。
由于在进行模式切换后，第二V2X业务实际所采用的通信模式与第二终端设备所决定的通信模式不同，因此再将第二V2X业务的通信模式从第一通信模式切换为第二通信模式后，如果符合预定条件，还可以再将第二V2X业务的通信模式切换回第一通信模式。
PC5-Uu资源调度功能，可以采用与前述实施例相类似的方式将第二V2X业务的通信模式从第二通信模式切换回第一通信模式。将第二V2X业务的通信模式从第二通信模式切换回第一通信模式可以通过前述实施例中的模式切换过程实现，也可以通过发送模式恢复指示实现。下面对通过发送模式恢复指示将第二V2X业务的通信模式从第二通信模式切换回第一通信模式进行进一步的说明。
参见图3，为本申请通信模式切换方法另一个实施例的流程图。如图3所示，在前述步骤206之后，还可以包括：
步骤207，PC5-Uu资源调度功能向V2X控制功能发送模式恢复指示。
PC5-Uu资源调度功能可以在符合预定条件时，向V2X控制功能发送模式恢复指示。所述模式恢复指示可以是删除模式变更请求(delete mode switch request)。其中，所述预定条件可以是第一V2X业务超过检测时长未进行数据传输。而所述检测时长可以由PC5-Uu资源调度功能在向V2X控制功能发送模式切换指示之前确定，根据第一V2X业务的不同，所述检测时长也可以各不相同。所述检测时长也可以采用其他方式设置，例如，所述检测时长也可以是由通信系统预先设定。
在将所述第二V2X业务的通信模式从第一通信模式切换为第二通信模式后，PC5-Uu资源调度功能可以启动定时器，所述定时器的时长可以是所述检测时长。如果在将第二V2X业务的通信模式从第一通信模式切换二通信模式后，在所述第一V2X业务超出所述检测时长未进行传输，或者第一V2X业务虽然进行数据传输，但是已经超出所述检测时长未再进行数据传输，那么PC5-Uu资源调度功能向V2X控制功能发送模式恢复指示。
所述模式恢复指示可以包含：第二终端设备的设备标识,第二V2X业务的service ID，第二切换命令等。其中，第二切换命令用于指示将第二V2X业务的通信模式切换回第一通信模式。或者，当所述切换标识相对于通信系统全局唯一时，所述模式恢复指示也可以仅包含所述切换标识；当所述切换标识相对于所述第二终端设备唯一时，所述模式恢复指示则可以包含所述切换标识及所述第二终端设备的设备标识。在此需要说明的是，由于第二切换命令与第一切换命令相比仅仅是内容的不同，因此再次就不再对第二切换命令进行详述，相关之处参见第一切换命令的相关内容即可。
步骤208，V2X控制功能向第二终端设备发送第二更新授权参数。
V2X控制功能在接收到PC5-Uu资源调度功能发送的模式恢复指示之后，根据模式恢复指示确定第二终端设备及第二V2X业务，并生成第二更新授权参数；然后将第二更新授权参数发送给第二终端设备，从而使所述第二终端设备按照所述更新授权参数的指示，将第二V2X业务的通信模式切换为第二通信模式。
V2X控制功能可以从所述模式恢复指示中获取切换标识及设备标识；然后从已经保存的切换记录中，获取与所述切换标识对应的业务标识及通信模式；根据从所述模式恢复指示中获取的设备标识确定所述第二终端设备；根据与所述切换标识对应的业务标识确定所述第二V2X业务；根据与所述切换标识对应的通信模式确定所述第二通信模式。在此需要说明的是，所述第二终端设备的设备的设备标识也可以由所述V2X控制功能从所述模式恢复指示中获取。
例如，如果所述模式恢复指示中包含Vehicle B，11，Uu-PC5，那么V2X控制功能就可以确定需要将终端设备标识为Vehicle B的终端设备上业务标识为11的业务的通信模式从Uu通信模式恢复为PC5通信模式。又如，如果所述模式恢复指示中包含switch 1，那么所述V2X控制功能可以查询switch 1中，所对应的模式切换，进而获取模式切换对应设备标识、业务标识及第二切换命令。从而确定需要将哪个终端设备上的哪个业务的通信模式从哪个通 信模式恢复为哪个通信模式。
在此需要说明的是，由于模式恢复指示与模式切换指示的生成和发送方式相类似，因此模式切换指示的具体生成和发送过程在此就不再赘述，相似之处参见模式切换指示的生成和发送的相关内容即可；类似的，第二更新授权参数与第一更新授权参数的生成和发送方式相类似，因此第一更新授权参数的具体生成和发送过程在此就不再赘述，相似之处参见第一更新授权参数的生成和发送的相关内容即可，在此也不再赘述。当模式恢复指示包含第二终端设备的设备标识,第二V2X业务的service ID，第二切换命令时，将第二V2X业务的通信模式从第二通信模式切换回第一通信模式，也可以被认为是对第二V2X业务进行通信模式切换。
在本实施例中，通过将第二V2X业务的通信模式从与第一通信模式切换为第二通信模式，可以为第一V2X业务调度出用于采用第一通信模式传输所述第一V2X业务的无线资源，当第一通信模式为PC5通信模式时，可以减少PC5空口资源量有限而导致V2V间通信出现资源拥堵、带宽不够或信号质量下降等情况的出现。
参见图4，为本申请通信模式切换方法另一个实施例的流程图。下面结合图4所示，以所述PC5-Uu资源调度功能为所述V2X控制功能的一部分或为所述V2X控制功能本身，即，所述PC5-Uu资源调度功能与所述V2X控制功能为同一设备为例对本申请进行说明。
步骤401，V2X控制功能在第一终端设备接入网络的过程中，向第一终端设备下发资源测量配置。
步骤402，第一终端设备在发起第一V2X业务时，根据测量配置进行测量。
步骤403，第一终端设备向V2X控制功能上报测量报告。
步骤404，V2X控制功能根据所述测量报告，确定需要由第一通信模式切换为第二通信模式的第二V2X业务。
在此需要说明的是，步骤401至步骤404的具体内容，可以参见步骤201至步骤204，在此就不再赘述。
步骤405，V2X控制功能向第二终端设备发送第一更新授权参数。
由于由V2X控制功能确定所述第二V2X业务，因此可以由V2X控制功能直接向第二终端设备发送第一更新授权参数。具体过程可以参见步骤206，在此就不再赘述。
类似的，在步骤405之后，还可以包括：
步骤406，V2X控制功能向第二终端设备发送第二更新授权参数。
在符合预定条件时，V2X控制功能可以向第二终端设备发送第二更新授权参数，第二更新授权参数的具体发送过程可以参见步骤206至步骤207，在此也不再赘述。
