Description

消息传输装置、方法以及通信系统 技术领域
本发明涉及通信领域，特别涉及一种消息传输装置、方法以及通信系统。
背景技术
最近，车与车(V2V，vehicle-to-vehicle)通信逐渐成为无线通信领域的研究热点。在未来，不仅车与车之间能够互相连接，而且车能够自由接入互联网。这种“车联网”是一个全新的概念。而且，大量的应用也会应运而生，从而显著地改变我们的生活。
因此，“车联网”已经吸引了大量研究机构和标准化组织的关注。到目前为止，已经涌现了大量的车与车通信系统和项目，典型的有电气和电子工程师协会(IEEE)802.11p的专用短距离通信系统(DSRC，dedicated short range communications)、智能交通系统(ITS，intelligent transportation system)等。
另一方面，长期演进(LTE，Long Term Evolution)/高级长期演进(LTE-Advanced)系统在全球范围的巨大成功为车与车通信带来了新的机遇，使得车与车相连、车与互联网相连成为可能。
相应地，第三代伙伴项目(3GPP，3rd generation partnership project)定义了三种场景：车与车(V2V，vehicle-to-vehicle)通信，车与行人(V2P，vehicle-to-pedestrian)通信以及车与网络(V2I/N，vehicle-to-infrastructure/network)通信，统称为V2X通信。V2X既可以通过PC5接口进行通信，也可以通过Uu接口进行通信。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现：例如V2V通信业务发生在相邻的车辆之间，基于Uu接口的V2V业务(例如广播或多播业务)也不例外。例如，如果发送V2V消息(例如广播或多播消息)的车辆用户设备位于小区中心位置，那么在该小区内广播或多播该消息就可 以了；如果发送广播或多播消息的车辆用户设备位于两个或者三个小区的交界处，那么最多只需要在这两个或者三个小区中广播或多播该消息。
然而，目前的方案中，对于每一条V2V消息(例如广播或多播消息)，服务小区的基站都会将其发送给所有相邻小区的基站，然后在所有相邻小区以及服务小区中广播或多播该V2V消息。显然，如此大范围的广播或多播是完全没有必要的。这样不仅会降低资源的使用效率，而且还会引入较大的时延。
本发明实施例提供一种消息传输装置、方法以及通信系统。缩小消息的传输范围并减少不必要的传输。

根据本发明实施例的第五个方面，提供一种通信系统，包括：

第一基站，其包括如第二方面所述的消息传输装置。
本发明实施例的有益效果在于：根据发送消息的用户设备所属的小区和/或所述用户设备的一个或多个相邻用户设备所属的小区确定所述消息的传输范围；由此可以缩小消息的传输范围并减少不必要的传输，不仅可以提高资源的使用效率，而且不会引入较大的时延。

下面结合附图对本发明实施例进行说明。

步骤102，基站确定该用户设备的一个或多个相邻用户设备；
步骤103，基站根据该用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，确定该消息的传输范围；
步骤104，基站基于该传输范围发送该消息。
在本实施例中，该用户设备例如可以是前述车联网的终端，但本发明不限于此，例如该用户设备还可以是其他网络系统的终端。此外，该消息可以是V2V消息，例如是广播或多播(broadcast/multicast)消息；但本发明不限于此，还可以是其他消息。本发明实施例仅以车联网为例进行说明，但并不限于此，可以适用于任何进行消息(例如广播或多播消息)传输的系统。在本实施例中，该基站为该用户设备所属小区的基站；该基站可以为宏基站(例如eNB)，用户设备由该宏基站产生的宏小区(例如Macro cell)提供服务；本发明实施例的基站也可以为微基站，用户设备由该微基站产生的微小区(例如Pico cell或micro cell)提供服务。本发明实施例不限于此，可以根据实际的需要确定具体的场景。
由上述实施例可知，基站根据发送消息的用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，来确定该消息的传输范围；与现有技术中“服务小区的基站将消息发送给所有相邻小区的基站”的方案相比，本发明可以缩小消息的传输范围并减少不必要的传输，不仅可以提高资源的使用效率，而且不会引入较大的时延。

在本实施例中，用户设备信息例如可以包括：用户设备的边链路标识(sidelink ID)和/或用户设备标识(UE ID)，但本发明不限于此；关于这些标识的具体内容可以参考相关技术。此外，可以通过基站间的接口(例如X2接口)直接进行交互，或者也可以通过基站与核心网之间的接口(例如S1接口)间接进行交互。
在本实施例中，信令交互可以被周期性地触发；例如每隔预定的时间进行一次交互。或者，也可以被来自相邻小区或核心网的请求触发；例如在接收到某一相邻小区的基站发送的请求时，与该相邻小区的基站进行一次交互。或者，还可以被事件触发。
例如，事件可以包括如下的其中一种或多种：进入小区的用户设备数目达到第一预设阈值，离开小区的用户设备数目达到第二预设阈值，进入小区的用户设备数目与离开小区的用户设备数目之和达到第三预设阈值。此外，上述事件中用户设备数目的计算可以是某个预定的时间内的，或者也可以是从上一次交互后累计的，等等。但本发明不限于此，例如还可以是其他的事件。
在本实施例中，可以在一次交互中将小区内的所有的用户设备信息(例如边链路标识和/或用户设备标识)发送给相邻小区的基站；这种交互方式可以称为绝对交互方式。
或者，也可以在一次交互中将小区内的与上一次交互不同的用户设备信息发送给相邻小区的基站；这种交互方式可以称为增量交互方式。即，每次交互过程中，只交互当前标识列表相对于上次交互列表的不同部分。
例如，可以交互一个元素类似于(+/-，ID)的列表。其中，“+”表示上次交互之后进入本小区的车辆用户设备；“-”表示上次交互之后离开本小区的车辆用户设备。ID为车辆用户设备的用户设备信息。但本发明不限于此，例如还可以采用其他的标识例如“*”“％”等表示，本发明并不对此进行限制。
再例如，可以交互两个列表：一个为上次交互之后进入本小区的车辆用户设备的用户设备信息列表；另一个为上次交互之后离开本小区的车辆用户设备的用户设备信息列表。
值得注意的是，以上仅示意性对基站之间如何交互用户设备信息进行了说明，但 本发明不限于此，可以根据实际情况确定具体的实施方式。通过基站之间的交互，某一基站可以获得一个或多个相邻用户设备所属小区的信息。
步骤202，用户设备上报相邻用户设备的信息。
在本实施例中，每一用户设备均可以向服务小区上报该用户设备的相邻用户设备的信息。例如可以周期性地上报，也可以被事件触发后上报相邻用户设备的边链路标识和/或用户设备标识。由此，基站可以获知本小区内的每一用户设备的相邻用户设备的用户设备信息。
步骤203，第一基站接收用户设备发送的某一个消息；
步骤204，第一基站确定该用户设备的一个或多个相邻用户设备；
例如，第一基站的小区内的UE1发送一个消息，第一基站可以根据步骤202获得的信息，确定该UE1的相邻用户设备(例如为UE2和UE3)。
步骤205，第一基站根据该用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，确定该消息的传输范围；
在本实施例中，第一基站可以将该用户设备所属小区(即第一基站对应的小区)确定为该消息的传输范围；此外，第一基站还可以根据步骤201获得的信息，确定发送该消息的用户设备(例如UE1)的相邻用户设备(例如UE2和UE3)所属的小区(例如对应第二基站)，并将相邻用户设备所属小区确定为该消息的传输范围。
步骤206，第一基站在本小区内发送该消息。
可选地，在相邻用户设备所属小区为第二基站对应的小区的情况下，该消息传输方法还可以包括：
步骤207，第一基站将该消息发送给第二基站。
步骤208，第二基站在本小区内发送该消息。
值得注意的是，图2仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，例如步骤206可以发生在步骤207之前，也可以与步骤207同时发生，或者步骤206也可以与步骤208同时发生，等等；图2中的执行顺序仅是本发明的一个例子。此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
以下通过一个实例对本实施例进行说明。
图3是本发明实施例的消息传输方法的实例图，如图3所示，共有三个小区，其中小区1(对应基站1)内有UE1和UE2(即UE1和UE2的所属小区为小区1)，小区2(对应基站2)内有UE3和UE4(即UE3和UE4的所属小区为小区2)，小区3(对应基站3)内有UE5(即UE5的所属小区为小区3)。其中UE1的相邻用户设备包括UE2和UE3(例如，UE1和UE2之间以及UE1和UE3之间进行V2V通信)。
例如，基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2和UE3；此外基站1可以和基站2、基站3进行信令交互，由此可以获知UE3在小区2内。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)，UE1相邻用户设备UE2和UE3所属的小区(分别为小区1和小区2)，确定该消息的传输范围为小区1和小区2。由此，基站1在小区1内发送该消息，并将该消息发送给基站2，由基站2在小区2内发送该消息。
由上述实施例可知，根据发送消息的用户设备所属的小区和/或一个或多个相邻用户设备所属的小区确定所述消息的传输范围；由此可以缩小消息的传输范围并减少不必要的传输，不仅可以提高资源的使用效率，而且不会引入较大的时延。
实施例3
本发明实施例在实施例1的基础上进一步说明；本发明实施例中服务基站将所有相邻小区确定为传输范围，进而由各相邻小区的基站自行判断是否在自己的小区内发送消息。
图4是本发明实施例的消息传输方法的示意图，以第一基站和与该第一基站相邻的第二基站为例进行说明。其中为简单起见，仅示意性示出了一个第二基站的情况，对于多个第二基站的情况可以类似的处理。
如图4所示，该消息传输方法包括：
步骤401，用户设备上报相邻用户设备的信息。
在本实施例中，每一用户设备均可以向服务小区上报该用户设备的相邻用户设备的信息。例如可以周期性地上报，也可以被事件触发后上报相邻用户设备的边链路标识和/或用户设备标识。由此，基站可以获知本小区内的每一用户设备的相邻用户设备的信息。
步骤402，第一基站接收用户设备发送的消息；
步骤403，第一基站确定该用户设备的一个或多个相邻用户设备；
步骤404，第一基站根据该用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，确定该消息的传输范围；
在本实施例中，第一基站可以将该用户设备所属小区(即第一基站对应的小区)以及全部相邻小区确定为该消息的传输范围。
步骤405，第一基站在本小区内发送该消息；
步骤406，第一基站将该消息以及相邻用户设备信息发送给全部相邻小区的基站(即第二基站)。
在本实施例中，该相邻用户设备信息可以包括：在该用户设备所属小区(即服务小区)内的相邻用户设备的用户设备信息，以及不在该服务小区内的相邻用户设备的用户设备信息；或者也可以仅包括不在该服务小区内的相邻用户设备的用户设备信息。
步骤407，第二基站根据相邻用户设备信息，确定是否在本小区内发送该消息。
值得注意的是，图4仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，例如步骤405可以发生在步骤406之前，也可以与步骤406同时发生，或者步骤405也可以与步骤407同时发生，等等；图4中的执行顺序仅是本发明的一个例子。此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
在本实施例中，对于每一个第二基站，在相邻小区(该第二基站对应的小区)内有该用户设备的相邻用户设备的情况下，第二基站在该相邻小区内发送该消息；在该相邻小区内没有该用户设备的相邻用户设备的情况下，第二基站不在该相邻小区内发送该消息。
仍以图3所示的实例对本实施例进行说明。
例如，基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2和UE3。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)以及全部相邻小区(小区2和小区3)，确定该消息的传输范围为小区1、 小区2和小区3。由此，基站1在小区1内发送该消息，并将该消息以及相邻用户设备信息发送给基站2和基站3。其中该相邻用户设备信息可以是UE2和UE3的用户设备信息，也可以仅是UE3的用户设备信息。
基站2接收到该消息以及UE1的相邻用户设备信息后，根据该UE1的相邻用户设备信息可以确定小区2内有UE1的相邻用户设备UE3，则基站2在小区2内发送该消息。
基站3接收到该消息以及UE1的相邻用户设备信息后，根据该UE1的相邻用户设备信息可以确定小区3内没有UE1的相邻用户设备，则基站3不在小区3内发送该消息。
由此，即使所有相邻小区的基站接收到了消息，也可以根据相邻用户设备的信息不在自己的小区内发送该消息，由此可以缩小消息的传输范围并减少不必要的传输。
在本实施例中，第一基站还可以先检查发送消息的用户设备的相邻用户设备，进一步减少不必要的传输。
图5是本发明实施例的消息传输方法的另一示意图，以第一基站和与该第一基站相邻的第二基站为例进行说明。其中为简单起见，仅示意性示出了一个第二基站的情况，对于多个第二基站的情况可以类似的处理。
如图5所示，该消息传输方法包括：
步骤501，用户设备上报相邻用户设备的信息。
在本实施例中，每一用户设备均可以向服务小区上报该用户设备的相邻用户设备的信息。例如可以周期性地上报，也可以被事件触发后上报相邻用户设备的边链路标识和/或用户设备标识。由此，基站可以获知本小区内的每一用户设备的相邻用户设备的信息。
步骤502，第一基站接收用户设备发送的消息；
步骤503，第一基站确定该用户设备的一个或多个相邻用户设备；
步骤504，第一基站检查该用户设备的所有相邻用户设备是否都在本小区(即该用户设备所属小区)内；
步骤505，第一基站根据该用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，确定该消息的传输范围；
在本实施例中，在该用户设备的所有相邻用户设备都在该用户设备所属小区(即 第一基站对应的小区)内的情况下，将该用户设备所属小区确定为该消息的传输范围；
在该用户设备的所有相邻用户设备不是都在该用户设备所属小区内的情况下，将该用户设备所属小区以及全部相邻小区确定为该消息的传输范围。
步骤506，第一基站在本小区内发送该消息。
可选地，在该用户设备的所有相邻用户设备不是都在该用户设备所属小区内的情况下，所述消息传输方法还可以包括：
步骤507，第一基站将该消息以及相邻用户设备信息发送给全部相邻小区的基站(即第二基站)。
在本实施例中，该相邻用户设备信息可以包括：在该用户设备所属小区(即服务小区)内的相邻用户设备的用户设备信息，以及不在该服务小区内的相邻用户设备的用户设备信息；或者也可以仅包括不在该服务小区内的相邻用户设备的用户设备信息。
步骤508，第二基站根据相邻用户设备信息，确定是否在本小区内发送该消息。
值得注意的是，图5仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，例如步骤506可以发生在步骤507之前，也可以与步骤507同时发生，或者步骤506也可以与步骤508同时发生，等等；图5中的执行顺序仅是本发明的一个例子。此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
在本实施例中，对于每一个第二基站，在相邻小区(该第二基站对应的小区)内有该用户设备的相邻用户设备的情况下，第二基站在该相邻小区内发送该消息；在该相邻小区内没有该用户设备的相邻用户设备的情况下，第二基站不在该相邻小区内发送该消息。
仍以图3所示的实例对本实施例进行说明。
例如，如果UE1的相邻用户设备仅为UE2；基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)以及UE1的相邻用户设备所属的小区(UE2的小区仍为小区1)，确定该消息的传输范围为小区1。由此，基站1仅在小区1内发送该消息。
再例如，如果UE1的相邻用户设备为UE2和UE3；基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2和UE3。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)以及UE1的相邻用户设备所属的小区(除了小区1外还有小区2)，确定该消息的传输范围为小区1以及全部相邻小区(小区2和小区3)。由此，基站1在小区1内发送该消息，并将该消息以及相邻用户设备信息发送给基站2和基站3。其中，该相邻用户设备信息可以包括UE2和UE3的用户设备信息，也可以仅包括UE3的用户设备信息。
基站2接收到该消息以及UE1的相邻用户设备信息后，根据该UE1的相邻用户设备信息可以确定小区2内有UE1的相邻用户设备UE3，则基站2在小区2内发送该消息。
基站3接收到该消息以及UE1的相邻用户设备信息后，根据该UE1的相邻用户设备信息可以确定小区3内没有UE1的相邻用户设备，则基站3不在小区3内发送该消息。
由上述实施例可知，根据发送消息的用户设备所属的小区和/或一个或多个相邻用户设备所属的小区确定所述消息的传输范围；由此可以缩小消息的传输范围并减少不必要的传输，不仅可以提高资源的使用效率，而且不会引入较大的时延。
实施例4

在该用户设备的所有相邻用户设备不是都在该用户设备所属小区内的情况下，第一基站将向相邻小区的基站查询相邻用户设备的情况。
步骤605，第一基站向第二基站进行相邻用户设备是否位于相邻小区内的查询；
在本实施例中，第一基站可以向第二基站发送查询请求，该查询请求中可以包括相邻用户设备信息(例如边链路标识和/或用户设备标识)列表。该相邻用户设备信息可以包括：在该用户设备所属小区(即服务小区)内的相邻用户设备的用户设备信息，以及不在该服务小区内的相邻用户设备的用户设备信息；或者也可以仅包括不在该服务小区内的相邻用户设备的用户设备信息。
如果第二基站对应的小区内有该用户设备的相邻用户设备，则第二基站会向第一基站反馈肯定回复；如果第二基站对应的小区内没有该用户设备的相邻用户设备，则第二基站会向第一基站反馈否定回复或者不回复。
步骤606，第一基站根据该用户设备所属的小区和/或一个或多个相邻用户设备所属的小区，确定该消息的传输范围；

仍以图3所示的实例对本实施例进行说明。
例如，如果UE1的相邻用户设备仅为UE2；基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)以及UE1的相邻用户设备所属的小区(UE2的小区仍为小区1)，确定该消息的传输范围为小区1。由此，基站1仅在小区1内发送该消息。
再例如，如果UE1的相邻用户设备为UE2和UE3；基站1可以接收UE1和UE2上报的信息，由此可以获知UE1的相邻用户设备为UE2和UE3。
在某一时刻，基站1接收到UE1发送的一个消息后，可以根据UE1所属的小区(小区1)以及UE1的相邻用户设备所属的小区(除了小区1外还有小区2)，向基站2和基站3分别发送查询请求(例如可以包括UE1的相邻用户设备UE2和UE3的标识，或者也可以仅包括UE3的标识)。基站2在接收到该查询请后，由于UE3在小区2内，则向基站1反馈肯定回复；基站3在接收到该查询请后，由于小区3内没有UE1的相邻用户设备，则向基站1反馈否定回复或者不反馈。
由此，基站1可以确定该消息的传输范围为小区1和小区2。基站1在小区1内发送该消息，并将该消息发送给基站2，由基站2在小区2内发送该消息。
由上述实施例可知，根据发送消息的用户设备所属的小区和/或一个或多个相邻用户设备所属的小区确定所述消息的传输范围；由此可以缩小消息的传输范围并减少不必要的传输，不仅可以提高资源的使用效率，而且不会引入较大的时延。
