Description

一种车联网通信方法及装置 技术领域
本发明涉及网络通信技术领域，特别涉及一种车联网通信方法及装置。
背景技术
近年来汽车网络越来越受到人们的关注，通过车车通信或者车与RSU(RoadSide Unit，路边单元)之间的通信，可以提高道路交通的安全性、可靠性，提升交通通行效率。
目前，根据IEEE(Institute of Electrical and Electronics Engineers，电气和电子工程师协会)标准扩充通信协议，用于车载电子无线通信，符合ITS(Intelligent Transportation Systems，智能交通系统)的相关应用。应用层面包括高速车辆之间以及车辆与ITS路边基础设施之间的数据交换。
现有技术中，主要利用蜂窝网络来协助进行车车通信的研究。
蜂窝通信采用2G、3G、4G等技术，在4G系统中采用的LTE(Long Term Evolution，长期演进)技术具有高速率，低延迟，大覆盖范围，以及支持高速移动终端等优点。在蜂窝网络中进行车车通信，可以充分利用中央调度器(如：eNB(evolved NodeB，基站))来进行传输资源的动态调度。
在LTE系统中，当UE(User Equipment，用户设备)有新数据要传输时，eNB需要为UE调度资源，然后UE在被调度的资源上传输BSR(Buffer Status Report，缓存状态报告)。如果UE需要向eNB上传其他信息，如：对于UE，上传车辆当前的行驶状态信息，则需要在上传BSR之后，继续利用PUSCH(Physical Uplink Shared Channel，物理上行共享信道)上传UE的信息。然而，这种技术实现方式具有明显的缺点：在上传BSR之后上传其他信息，将会导致额外的传输时延。而车辆传输安全消息对时延的要求很高，因此可能会因为上传当前的行驶状态信息而导致较大的时延，从而降低安全消息传输的性能。

具体实施方式
为了使本技术领域的人员更好地理解本发明实施例中的技术方案，并使本发明实施例的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明实施例中技术方案作进一步详细的说明。
如图1所示，为本发明提供的一种车联网通信方法实施例，该方法可以包括以 下执行步骤：
步骤101、UE向基站发送调度请求。
本发明实施例为LTE系统中的车联网通信过程。
在LTE系统中，当UE需要向基站传输数据信息时，UE需要首先向基站发送SR(Scheduling Request，调度请求)。基站接收到UE上传的SR，获知UE当前有数据需要传输。
步骤102、UE接收基站发送的分配BSR传输资源的通知信息。
该步骤中，当基站接收到UE上传的SR之后，为UE随后将要上传的BSR调度传输资源，并向UE发送分配BSR传输资源的通知信息。从而，UE可以通过基站调度的传输资源，上传BSR。
步骤103、UE在基站分配的BSR传输资源上传输BSR，BSR中携带UE的行驶状态信息，行驶状态信息用于基站根据行驶状态信息为UE分配适于当前行驶状态的无线资源。
本发明实施例中，与现有技术不同的是，UE上传的BSR中携带UE当前的行驶状态信息。这是由于，基站为UE分配无线资源时，通常需要考虑UE当前的行驶状态，从而可以更加有效的进行资源调度。例如：如果基站知道UE的位置信息，可以为空间相距很远的UE分配相同的资源，从而实现资源的复用，提高资源利用率。如果基站知道UE的速度信息，可以将高速移动的UE调度到竞争资源，从而降低UE快速驶出小区而带来的频繁切换问题。因此，基站需要获取UE当前的行驶状态信息。本发明实施例中，该无线资源用于UE与其他UE、RSU或者其他终端的通信。
具体地，行驶状态信息可包括但不限于：UE当前所处位置信息、移动速度信息或移动方向信息中的至少一种信息。本发明实施例中，通过直接在UE上传的BSR中携带UE当前的行驶状态信息，从而不需UE额外利用其它信令调度资源向基站传输行驶状态信息。
当基站获取UE当前的行驶状态信息之后，将根据UE当前的行驶状态以及缓存区的状态，为UE分配适于当前行驶状态的无线资源。
步骤104、UE利用分配的无线资源进行数据传输。
该步骤中，当基站为UE分配适于当前行驶状态的无线资源之后，UE可以利用 分配的无线资源进行数据传输。
本发明实施例中，UE在基站分配的传输资源上传输BSR的同时，利用该BSR携带UE当前的行驶状态信息，由此，基站根据UE上传的BSR，除了可以获知UE所传输的业务包的缓存大小信息之外，同时可以获知车辆当前的行驶状态信息，从而，不需UE额外利用其它信令调度资源向基站传输行驶状态信息。因此，可以缩短UE上传行驶状态信息的时间，减少UE上传状态信息的时延，提高UE上传行驶状态信息的效率。
下面通过具体实施例，对上述BSR中携带UE行驶状态信息的具体实现方式进行详细说明。
具体实施过程中，可以在BSR中显式传输UE的行驶状态信息，即：直接在BSR中显式加载UE的行驶状态信息。
在现有LTE系统中，BSR通常有两种格式：短(Short)BSR格式和长(Long)BSR格式，分别如图2和图3所示。
在图2所示的Short BSR格式中，Short BSR中包含两个信息域：LCG ID(Logical Channel Group Identity，逻辑信道组识别号)、对应LCG ID的缓存大小指示域(Buffer Size)。
在图3所示的Long BSR格式中，Long BSR中包含四个缓存大小指示域，分别对应着LCG ID#0到#3。图3中的Oct表示八进制(Octal)，Oct1表示第一组八比特(bit)，Oct1～Oct3各表示一个八比特，即：利用24比特表示一个Long BSR。
本发明实施例中，分别在现有Short BSR格式和Long BSR格式的BSR中增加标识UE行驶状态信息的信息域，称为“行驶状态信息指示域(Status information)”。该实现方式下，Short BSR格式的BSR和Long BSR格式的BSR分别如图4和图5所示。
在图4所示的Short BSR格式中，Short BSR中包含三个信息域：LCG ID、对应LCG ID的缓存大小指示域(Buffer Size)以及行驶状态信息指示域(Status information)。其中，LCG ID和Buffer Size构成一个字节(byte)，Status information含有N个byte，可以利用该信息域的N个字节加载一种或者多种状态信息。
在图5所示的Long BSR格式中，Long BSR中包含两个信息域：Buffer size和Status information。其中，Buffer size域包含四个指示信息域，分别对应四个逻辑信道 组，其ID为LCG ID#0到LCG ID#3。Status information含有N个byte，同样，可以利用该信息域的N个字节加载一种或者多种状态信息。
具体地，UE的行驶状态信息可以包括：UE所处位置信息、移动速度(SPEED)信息或移动方向(DIRECTION)信息。由此，本发明实施例可以利用BSR中增加的行驶状态信息指示域(Status information)直接加载UE所处位置信息、移动速度信息或移动方向信息中的任意一种或多种状态信息。
需要说明的是，除了在BSR中显式加载UE的行驶状态信息，还可以采用隐式的方式通过BSR传输UE的行驶状态信息。
如图7所示，为UE通过BSR传输UE的行驶状态信息的过程，其中包括：
步骤701、UE获取标识UE行驶状态的索引关系；
步骤702、UE根据索引关系，确定当前行驶状态对应的索引值；
步骤703、UE在BSR中加载索引值。
具体地，基站可以在小区范围内广播标识UE行驶状态的索引关系，或者是终端通过预定义的方式获取标识UE行驶状态的索引关系，即：不同索引值对应UE的不同行驶状态。当UE获得标识UE行驶状态的索引关系之后，将根据该索引关系，确定自身当前行驶状态所对应的索引值；进而，将确定出的索引值加载在BSR中，上传至基站。从而，基站根据接收到的索引值，通过查找之前已广播的索引关系，或者预定义的索引关系，可以最终确定UE当前的行驶状态信息。
下面以基站广播标识UE行驶状态的索引关系的实现方式为例，对在BSR中隐式传输UE的行驶状态信息的方式进行详细说明。
具体应用场景中，基站可以将速度或移动方向划分为多个区间，不同的区间对应不同的索引关系，并将速度区间或移动方向区间划分的准则和相对应的索引号在小区内广播。UE能够根据自身当前的移动速度判断处于哪个速度区间或根据自身当前的移动方向判断处于哪个移动方向区间，并且将对应的索引号加载在BSR中上传至基站。
对于UE的移动速度，数值范围为[0，X]km/h。在BSR中可以用M bit指示该移动速度，M越大，指示的速度信息越精确。下面给出了速度信息的两种指示方法。
在第一种方法中，利用BSR中Status information信息域中的Mbit信息指示具体 的速度大小，速度大小精确到1km/h。具体实施例如下表1所示，其中，X＝600。表1左侧是M＝8时的速度指示示例，此时如果终端速度大于等于254km/h，则用索引254表示；右侧是M＝9时的速度指示示例，此时如果终端速度大于等于510km/h，则用索引510表示。
表1

在第二种方法中，可以将速度范围分为多个速度区间，每个速度区间间隔为Y km/h，利用BSR中Status information信息域中的M bit信息指示不同的速度区间。具体实施例如下表2所示，其中，X＝300，Y＝5，M＝8，如果终端速度大于300km/h，则用索引62表示。
表2

此外，对于UE的移动方向，数值范围是：[0,360]度，正北方向对应0度方向，正东方向对应90度方向，正南方向对应180度方向，正西方向对应270度方向，如图6所示。利用BSR中Status information信息域中的N bit信息指示不同的方向，N越大，指示的方向信息精度越高。
在移动方向的第一种指示方法中，利用BSR中Status information信息域中的Nbit信息指示具体的方向，方向信息精确到1度。具体实施例如下表3所示，其中，N＝9。
表3

在移动方向的另一种指示方法中，将方向大小范围分为多个区间，每个区间间隔为Y度，利用BSR中Status information信息域中的N bit信息指示不同的方向区间。具体实施例如下表4所示，其中，Y＝2，N＝8。

另外，基站还可以将本小区的覆盖范围按照地理位置划分为多个小的区域，每个区域对应不同的索引关系，并将区域划分的准则以及相应不同区域的索引号在本小区内广播。小区内的所有UE能够根据当前所处的位置信息，判断自身处于哪个区域，并且将相对应的区域索引号加载在BSR中上传至基站。
对于UE所处位置信息，由于位置信息包含经度、纬度和高度信息，可以分别对这三种信息进行指示。
经度数值范围为(-180，180)度。在BSR中可以用K1bit指示经度信息，K1越大，指示的经度信息越精确。可以将经度信息分为大小相同的经度范围，经度间隔为Y1。具体实施例如下：如果Y1＝1微度，则需要指示的经度范围是(-180.000000，180.000000)度，经度信息unavailable，用180.000001表示，此时K1＝29。如果Y1＝1毫度，则需要指示的经度范围是(-180.000，180.000)度，经度信息unavailable，用180.001表示，此时K1＝19。
纬度数值范围为(-90，90)度。在BSR中可以用K2bit指示纬度信息，K2越大，指示的纬度信息越精确。可以将纬度信息分为大小相同的纬度范围，纬度间隔为Y2。具体实施例如下：如果Y2＝1微度，则需要指示的纬度范围是(-90.000000，90.000000)度，纬度信息unavailable，用90.000001表示，此时K2＝28。如果Y2＝1毫度，则需要指示的纬度范围是(-90.000，90.000)度，纬度信息unavailable，用90.001表示，此时K2＝18。
高度数值范围可以根据经验值进行设置，例如(-1000，8000)米。其中，海平 面对应0米，如果高度低于海平面1000米，则用-1000米表示，如果高度高于海平面8000米，则用8000米表示。在BSR中可以用K3bit指示高度信息，K3越大，指示的高度信息越精确。可以将高度分为大小相同的高度区间，间隔为Y3米。具体实施例如下：如果Y3＝0.01，则需要指示的高度范围是(-1000.00，8000.00)，高度信息unavailable，用8000.01表示，此时K3＝20。
上述车联网通信方法实施例，从UE一侧，描述了通信的相关流程。下面从基站一侧，继续描述相关的通信流程。
如图8所示，为本发明提供的一种车联网通信方法实施例，该方法可以包括以下执行步骤：
步骤801、基站接收UE发送的调度请求。
在LTE系统中，当UE需要向基站传输数据信息时，UE需要首先向基站发送SR。基站接收到UE上传的SR，获知UE当前有数据需要传输。
步骤802、基站接收调度请求后，为UE分配BSR传输资源，并向UE发送分配BSR传输资源的通知信息。
该步骤中，当基站接收到UE上传的SR之后，为UE随后将要上传的BSR调度传输资源，并向UE发送分配BSR传输资源的通知信息。从而，UE可以通过基站调度的传输资源，上传BSR。
步骤803、基站接收UE在BSR传输资源上传输的BSR，BSR中携带UE的行驶状态信息。
该步骤中，与现有技术不同的是，UE上传的BSR中携带UE当前的行驶状态信息。这是由于，基站为UE分配无线资源时，通常需要考虑UE当前的行驶状态。例如：如果基站知道UE的位置信息，可以为空间相距很远的UE分配相同的资源，从而实现资源的复用，提高资源利用率。如果基站知道UE的速度信息，可以将高速移动的UE调度到竞争资源，从而降低UE快速驶出小区而带来的频繁切换问题。因此，基站需要获取UE当前的行驶状态信息。
具体地，行驶状态信息可包括但不限于：UE当前所处位置信息、移动速度信息或移动方向信息中的至少一种信息。本发明实施例中，通过UE直接在上传的BSR中加载UE当前的行驶状态信息，从而不需UE额外利用其它信令调度资源向基站传 输行驶状态信息。
步骤804、基站根据行驶状态信息为UE分配适于当前行驶状态的无线资源。
该步骤中，当基站获取UE当前的行驶状态信息之后，将根据UE当前的行驶状态，为UE分配适于当前行驶状态的无线资源。
本发明实施例中，UE在基站分配的传输资源上传输BSR的同时，利用该BSR携带UE当前的行驶状态信息，由此，基站根据UE上传的BSR，除了可以获知UE所传输的业务包的缓存大小信息之外，同时可以获知车辆当前的行驶状态信息，从而，不需UE额外利用其它信令调度资源向基站传输行驶状态信息。因此，可以缩短UE上传行驶状态信息的时间，减少UE上传状态信息的时延，提高UE上传行驶状态信息的效率。
具体实施过程中，UE可以在BSR中显式传输UE的行驶状态信息，即：直接在BSR中显式加载UE的行驶状态信息。
本发明实施例中，分别在现有Short BSR格式和Long BSR格式的BSR中增加标识UE行驶状态信息的信息域，称为“行驶状态信息指示域”。
其中，Short BSR中包含三个信息域：LCG ID、对应LCG ID的缓存大小指示域(Buffer Size)以及行驶状态信息指示域(Status information)。其中，LCG ID和Buffer Size构成一个字节(byte)，Status information含有N个byte，可以利用该信息域的N个字节加载一种或者多种状态信息。
Long BSR中包含两个信息域：Buffer size和Status information。其中，Buffer size域包含四个指示信息域，分别对应四个逻辑信道组，其ID为LCG ID#0到LCG ID#3。Status information含有N个byte，同样，可以利用该信息域的N个字节加载一种或者多种状态信息。
具体地，UE的行驶状态信息可以包括：UE所处位置信息、移动速度(SPEED)信息或移动方向(DIRECTION)信息。
此外，除了在BSR中显式加载UE的行驶状态信息，还可以采用隐式的方式通过BSR传输UE的行驶状态信息。
具体地，基站可以在小区范围内广播标识UE行驶状态的索引关系，或者是终端通过预定义的的方式获取标识UE行驶状态的索引关系，即：不同索引值对应UE的不同行驶状态。当UE获得标识UE行驶状态的索引关系之后，将根据该索引关系， 确定自身当前行驶状态所对应的索引值；进而，将确定出的索引值加载在BSR中，上传至基站。从而，基站根据接收到的索引值，通过查找之前已广播的索引关系，或者预定义的索引关系，可以最终确定UE当前的行驶状态信息。
在BSR中隐式传输UE的行驶状态信息的详细方式已在前面实施例中进行了详细说明，此处不再进行赘述。
相应上述车联网通信方法实施例，本发明提供了一种车联网通信装置。

传输模块903，用于利用所述基站分配的无线资源进行数据传输。
本发明实施例中，与现有技术不同的是，UE通过BSR上传模块上传的BSR中携带UE当前的行驶状态信息。这是由于，基站为UE分配无线资源时，通常需要考虑UE当前的行驶状态。例如：如果基站知道UE的位置信息，可以为空间相距很远的UE分配相同的资源，从而实现资源的复用，提高资源利用率。如果基站知道UE的速度信息，可以将高速移动的UE调度到竞争资源，从而降低UE快速驶出小区而带来的频繁切换问题。因此，基站需要获取UE当前的行驶状态信息。

除此之外，还可以在BSR中显式传输UE的行驶状态信息，即：直接在BSR中显式加载UE的行驶状态信息。
显式传输UE的行驶状态信息的方式中，上述BSR上传模块，具体在BSR中增加的行驶状态信息指示域中的多个字节上加载UE的行驶状态信息。

无线资源分配模块1104，用于在BSR接收模块接收UE在BSR传输资源上传输的BSR之后，根据行驶状态信息为UE分配适于当前行驶状态的无线资源。
该实施例中，UE上传的BSR中携带UE当前的行驶状态信息。这是由于，基站为UE分配无线资源时，通常需要考虑UE当前的行驶状态。例如：如果基站知道UE的位置信息，可以为空间相距很远的UE分配相同的资源，从而实现资源的复用，提高资源利用率。如果基站知道UE的速度信息，可以将高速移动的UE调度到竞争资源，从而降低UE快速驶出小区而带来的频繁切换问题。因此，基站需要获取UE当前的行驶状态信息。
