智能交通系统(Intelligent Transport System，ITS)又称智能运输系统(Intelligent Transportation System)，其将信息技术、计算机技术、数据通信技术、传感器技术、电子控制技术、自动控制技术、人工智能技术等运用于交通运输、服务控制和车辆制造中，加强车辆、道路、使用者三者之间的联系，从而形成一种保障安全、提高效率、改善环境、节约能源的综合运输系统。
在智能交通系统中，车辆需要向网络控制中心进行认证，并且在高速行驶过程中，能够实现漫游、切换；车辆需要周期性地上报位置信息，并且这些位置信息需要以极低的时延传送到周边的车辆中。在与智能交通系统类似的要求低时延的通信系统中也存在类似问题。例如，在这些通信系统中，用户设备之间交互的信息需要通过无线接入网设备和核心网设备进行传输，使得这些信息的传输时延较高，无法满足低时延的要求。从而无法保证每个车辆能够及时地接收到其它车辆发来的即时信息，所述即时信息为对传输实时性要求非常高的信息(属于本发明中所指的局部信息)，例如刹车、加速、变道、突发事故、突发故障等信息。这些信息直接影响着智能交通的秩序。
因此，车辆在刹车、加速、减速时，如何把这些行驶状态信息快速地传送到周边的车辆，避免发生交通事故如何降低智能交通系统的传输时延是智能交通系统中亟待解决的问题。

本发明的这些和其它方面在以下多个实施例的描述中会更加简明易懂。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是 全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明的技术方案可以应用于各种通信系统，例如：GSM(Global System of Mobile communication，全球移动通讯)系统、CDMA(Code Division Multiple Access，码分多址)系统、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)系统、GPRS(General Packet Radio Service，通用分组无线业务)、LTE(Long Term Evolution，长期演进)系统、LTE-A(Advanced long term evolution，先进的长期演进)系统、UMTS(Universal Mobile Telecommunication System，通用移动通信系统)以及智能交通系统等，本发明实施例并不限定，但为描述方便，本发明实施例将以智能交通系统为例进行说明。
本发明实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的网元。例如，LTE和LTE-A中无线接入网络的网元包括eNB(eNodeB，演进型基站)，WCDMA中无线接入网络的网元包括RNC(Radio Network Controller，无线网络控制器)和NodeB，类似地，WiMax(Worldwide Interoperability for Microwave Access，全球微波互联接入)等其它无线网络也可以使用与本发明实施例类似的方案，只是基站系统中的相关模块可能有所不同，本发明实施例并不限定，但为描述方便，下述实施例将以eNodeB为例进行说明。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)、及便携设备(portable equipment)等，该用户设备可以经无线接入网(RAN，Radio Access Network)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置(例如，OBU)。
利用蜂窝网络实现移动通信时，UE将信息传输给基站，基站通过光纤将信息传输给核心网，核心网对信息进行处理，并将信息通过光纤传输给基站，基站再将信息通过无线传输给目标UE。由于UE之间的通信需要经过核心网，使得直接将蜂窝网络应用于诸如智能交通系统之类的高速移动场景时不能满足低时延的要求。
虽然无线局域网技术具有低时延的特点，但无线局域网系统中没有核心网，在安全认证、系统调度方面存在不足，无法实现漫游、切换。另外，无线局域网支持的最大速度为70km，无法满足智能交通系统之类的高速移动场景的需要。
本发明的实施例提出了一种传输信息的方法和用户设备。本发明的实施例可以应用于通用蜂窝系统或专用集群通信系统。例如，本发明的实施例可以将蜂窝网络技术应用于高速移动场景(例如，智能交通系统)。本发明的实施例采用一跳式的通信方案，即由基站将一个用户设备上报的局部信息直接下发给其它用户设备，无需经过核心网设备，能够降低通信系统的时延。全局信息可以为核心网设备使用的信息，局部信息可以为基站覆盖下(即本地的)的用户设备使用的信息。换句话说，应用于整个通信系统的信息称为全局信息，而应用于某个基站本地的用户设备的信息称为局部信息。以智能交通系统为例，全局信息可以包括用于智能交通系统进行交通控制的信息，局部信息可以包括用于基站覆盖下的车辆间进行行驶控制的信息。
应理解，虽然本发明的实施例是以智能交通系统的场景为例进行描述，但本发明的实施例并不限于此，例如，本发明的实施例还可以应用于其它任何需要降低时延的通信系统中。
请参阅图1-a，图1-a是根据本发明的一个实施例的通信系统100的示意性架构图。
通信系统100包括核心网设备110、第一基站120、用户设备130、用户设备140、第二基站150以及用户设备160。第一基站120、第二基站150与核心网设备110之间可以通过光纤连接，第一基站120、第二基站150可以通过S1接口与核心网设备110通信，用户设备130和140与第一基站120之间通过无线连接，用户设备160与第二基站150之间通过无线连接，第一基站120可以通过空口与用户设备130和140通信，第二基站150可以通过空口与用户设备160通信，第二基站为与第一基站相邻的基站，用户设备130用户设备140均在第一基站120覆盖的通信小区中，用户设备160在第二基站150覆盖的通信小区中。另外，通信系统100还可以包括数据中心或控制中心(未示出)，例如，该数据中心或控制中心可以通过光纤与核心网设备连接。应理解，为了描述方便，用户设备130、140、160并非只指一个终端，而是代表着一类终端，在具体实现过程中既可以是一个，也可以是多个。
用户设备130用于向第一基站120发送上行信息，第一基站120用于分析用户设备130发送的上行信息，并从上行信息中确定出上心信息中哪些信息是局部信息哪些是全局信息。第一基站120可以将全局信息上传给核心网设备110，并且将局部信息直接下发给本地的其它用户设备140。核心网设备110用于对全局信息进行处理。用户设备140用于接收并使用局部信息。另外，数据中心用于执行智能交通系统的路径规划、分析车辆的安全状况等功能。
请参阅图1-b，图1-b是交通通信系统中的一种应用场景。当第一基站120接收到用户设备130所上报的局部信息时，为了降低时延不经过核心网直接下发给第一基站120覆盖的通信小区中的用户设备140了，然而距离用户设备130也很近的用户设备160却由于没有处于第一基站120所覆盖的通信小区中，而无法获知用户设备130所上报的局部信息，因此导致用户设备160由于接收不到全面的信息从而在做出决策时带来安全隐患。因此本发明提供了一种传输信息的方法，即第一基站120将用户设备130上报的局部信息发送给相邻基站，如第二基站150，再有第二基站150能够下发给用户设备160，这样使得用户设备130附近的用户设备都能够获得用户设备130所上报的局部信息，并根据局部信息中的交通即时状态改变而对自身所在车辆实行控制调节。
本发明的实施例对核心网设备和用户设备的处理功能不作限定。例如，当通信系统100为智能交通系统时，用户设备130和用户设备140可以为车载单元(On Board Unit，OBU)，也可以是附带该车载单元的车辆或其它终端设备。核心网设备可以根据接收到的全局信息进行安全认证、漫游和切换等处理，而车载单元可以根据接收到的局部信息进行自动驾驶等处理。本发明的实施例并不限于此，在智能交通系统中，核心网设备和用户设备还处理类似娱乐信息、购物信息等不同应用的信息。
请参阅图2，图2是根据本发明的一个实施例的传输信息的方法流程图。该方法包括以下步骤：
S101：第一基站接收第一用户设备发送的上行信息，上行信息中包含第一信息，第一信息中含有指示信息，指示信息用于指示第一信息为全局信息还是局部信息；其中，第一用户设备处于第一基站覆盖的通信小区；
S102：第一基站根据指示信息判断第一信息是全局信息还是局部信息； 若第一基站判断第一信息为局部信息，则执行S103；若第一基站判断第一信息为全局信息，则执行S104。
S103：第一基站将第一信息发送给第二基站，其中，第二基站为预置临区列表中与第一基站具有相邻关系的基站。
在具体实现过程中，第一基站可以对所述第一信息增加标签，标签用于指示第二基站第一信息为局部信息，以便于第二基站无需对第一信息再进行解析和判断就可以将第一信息直接发送至第二用户设备，第二用户设备处于所述第二基站覆盖的通信小区。通常第二基站不会再将第一信息转发给其他基站和核心网。
此外，第一基站还可以将第一信息发送给第一基站所覆盖的通信小区中个第三用户设备。
基站与基站之间的通信可以通过X2接口来完成。
为了数据备份与统计，第一基站还可以将第一信息发送给核心网设备。
S104：第一基站将第一信息发送给核心网设备。
在一种可能的设计中，指示信息可以是第一信息中新增的指示字段，指示字段为第一标识或第二标识，第一标识用于指示第一信息为全局信息，第二标识用于指示所述第一信息为局部信息；其中，第一标识与第二标识不同。指示字段可以由用户设备按照预定机制来设置。本发明中说指的新增的指示字段，既包含增加新的字段，还包括利用已有的特殊字段进行字段替换，用来区分全局信息和局部信息。
具体而言，上述指示信息可以是所发送数据包中的一个指示字段或指示域或指示位，用于指示数据包发送(或携带)的信息是全局信息还是局部信息。以指示字段为例，本发明的实施例可在上行信息的数据包中设置指示字段。该指示字段可以是常规帧格式的数据包中的新增字段，也可以是常规帧格式的数据包中的保留字段。例如，用一个比特(bit)位来指示局部信息或全局信息，例如，第一标识可以为0，用于指示全局信息，第二标识可以为1，用于指示局部信息，根据本发明的实施例并不限于此，第一标识和第二标识也可以是其它数值和/或字母的组合。特别地，也可以是该指示字段存在时表示全局信息，该指示字段不存在时表示局部信息，在这种情况下，第一标识为该字段上填充的信息，第二标识为空(Null)。
下面详细描述几种携带指示信息的方式。本发明实施例的各种指示信息 均可以采用以下方式来携带。
1)指示信息可以在物理上行控制信道(Physical Uplink Control Channel，PUCCH)中承载(或携带)。例如，上行信息可以由控制信息和数据信息组成，其中控制信息在PUCCH上发送，数据信息在物理上行共享信道上(Physical Uplink Shared Channel，PUSCH)传送，本发明的实施例可以在PUCCH上承载(或携带)指示信息，在PUSCH上承载全局信息或局部信息。
2)指示信息可以通过参考信号来指示，即全局信息和局部信息可以采用不同的参考信号来指示。例如，在每个资源块(Resource Block，RB)中参考信号(Reference Signal，RS)中指示。该指示信息可以通过改进现有的参考信号，也可以设计一个新的参考信号。
3)指示信息可以通过前导(preamble)来指示，即全局信息和局部信息可以采用不同的前导。
由于用户设备在上行信息中明确标识了全局信息和局部信息，基站通过简单读取指示信息即可对上行信息进行分类，使得基站可以快速地区分出局部信息和全局信息，并可以快速下发局部信息，从而最大限度地降低了信息传输的时延。
作为在上行信息中包含指示字段的替代方案，基站可以根据全局信息和局部信息的内容和/或属性特征从上行信息中确定全局信息和局部信息。
例如，需要核心网处理的全局信息可以是用户标识和密码等安全和认证信息，而需要本地用户设备处理的可以是经度和纬度等位置信息，基站可以分析这两种信息在内容上的不同之处来识别这两类信息。或者，基站可以根据两类信息的特点(例如，数据包的长度)来识别这两类信息。这种方案无需对用户设备进行改造即可实现，简化了系统的设计。
在一种可能的设计中，指示信息为目标地址信息；目标地址信息为第一地址或第二地址，第一地址用于指示第一信息为全局信息，第二地址用于指示第一信息为局部信息；其中，第一地址与第二地址不同；第一地址包括核心网设备地址；第二地址包括除核心网设备地址以外的地址。
具体而言，可以根据上行信息是否设置有目标地址和具体的值来判断全局信息和局信息。例如，用户设备在发送全局信息时，可以在上行信息中设置目标地址，而在发送局部信息时可以不在上行信息中设置目标地址，这样， 基站在若确定上行信息中没有目标地址，则可以认为该上行信息是局部信息，若确定上行信息中有目标地址，则认为该上行信息是全局信息。再如，用户设备在发送上行信息时可以将目标地址设置为某个特定的数值，例中，设置为1时，表示该上行信息为局部信息，设置为数值2时，代表该上行信息为全局信息。另外地址还可以是明确的路由地址、IP地址、邮件地址等。
在一种可能的设计中，指示信息为第一信息的帧格式，帧格式包括：调制方式；其中全局信息采用第一载波调制，局部信息采用第二载波调制，第一载波和第二载波存在预设相位差；因此全局信息的帧格式信息不同于局部信息的帧格式信息。
具体而言，用户设备可以在特定的位置使用不同的调制方法来调制全局信息和局部信息，基站则通过判断上行信息的调制方式来区分全局信息和局部信息，例如，全局信息使用普通的双相移位键(Binary Phase Shift Keying，BPSK)调制，而局部信息使用旋转90度(或45度)的BPSK调制。
此外，用户设备还可以为上行信息设置不同帧长，基站通过判断上行信息的帧长来区分全局信息和局部信息，例如，全局信息的帧长均为奇数，局部信息的帧长均为偶数。用户设备还可以为上行信息设置不同的字段的数目，基站通过判断上行信息的字段的数目来区分全局信息和局部信息，例如，全局信息含有M个字段，局部信息含有N的字段，M不等于N，M和N为整数；一种可能是实施方式，M大于N。
上述几种形式的指示信息可以由用户设备在发送局部信息时进行相应地设置，具体的设置过程由上报局部信息的用户设备的信息处理机制决定。
本发明中，第一用户设备和第二用户设备包括智能交通系统中的车辆上附带的车载单元，实现形式不限于手机、平板电脑、车载导航、行车记录仪、可穿戴设备等智能终端，在所述局部信息包括车联网车辆之间行驶状态信息，所述行驶状态信息用于所述第二用户设备或所述第三用户设备进行行驶控制。
根据本发明的实施例，第一基站可以根据指示信息从用户设备发送的上行信息中识别全局信息和局部信息，若指示信息指示上行信息包含全局信息，向核心网设备上传全局信息，若指示信息指示上行信息包含局部信息，则直接向相邻基站发送局部信息，以便于相邻基站能够将局部信息下发至自自己覆盖的小区中的用户设备，从而缩短了数据信息的传输路径，降低了数 据信息的传输时延，提高了数据信息的传输速度；由于局部信息无需再经过核心网转发，因此降低了局部信息的传输时延，从而降低了通信系统的时延。另外，在局部信息不经过核心网处理的情况下还能减轻核心网的负担。
请参阅图3，图3是根据本发明的另一个实施例的传输信息的方法流程图。该方法包括以下步骤：
S201：第二基站接收第一基站发送的第一信息，第一信息中含有指示信息，指示信息用于指示第一信息是否为局部信息；其中，第一基站为预置临区列表中与第二基站具有相邻关系的基站。
S202：第二基站根据指示信息判断第一信息是否是局部信息。
S203：第二基站判断第一信息为局部信息，则第二基站将第一信息发送给第二用户设备，其中第二用户设备处于第二基站覆盖的通信小区。
作为补充，如果第二基站判断第一信息不是局部信息，则按照现有标准对第一信息进行相应的处理。
其中，这里的指示信息在上述实施例中已经进行了详细的解释和举例说明，此处不再赘述。
此外，这里的指示信息还可以为第一基站在判断出第一信息为局部信息时，在第一信息中增加的标签，该标签用于指示第二基站第一信息为局部信息。这样减少了第二基站对第一信息本身进行的再一次判定，不用根据上述的指示字段、帧格式、目标地址等各种特征再重复判定，第一基站直接增加统一的标签，使第二基站能够更加有效地、快速地识别出来第一信息为局部信息，快速下发减少传输延时。
请参阅图4，图4是根据本发明的另一个实施例的传输信息的方法流程图。该方法包括以下步骤：
S301：用户设备生成上行信息，其中上行信息中包含第一信息；
S302：用户设备在第一信息中设置指示信息，指示信息用于指示第一信息是全局信息还是局部信息；
S303：用户设备向基站发送所述上行信息，以便于基站能够根据指示信息判断第一信息为局部信息还是全局信息。
在具体实现过程中，用户设备设置指示信息的方式在上述实施例中已经进行描述，此处不再赘述。
应理解，用户设备可以同时上报全局信息和局部信息，也可以分别上报 全局信息和局部信息，例如，在接入网络过程中，用户设备可以通过基站向核心网设备上报安全证信息，或者在漫游和切换过程中，用户设备可以通过基站向核心网设备上报漫游和切换相关信息，而在接入网络后向基站发送位置信息和速度信息以及车辆的转向、制动和加速等操作信息。
下面将以智能交通通信系统为例，车辆可以在不同场景下生成不同的上行信息，例如，在车辆接入网络时，生成安全认证信息、在车辆进行漫游和切换时，生成漫游和切换相关信息。在车辆行进时，可以生成位置信息和速度信息等信息。还可以生成常规智能交通系统中需要上报的其它任何信息，例如，娱乐信息等。例如，车辆1可以利用自身携带的GPS(全球定位系统，Global Positioning System)检测车辆1的位置，还可以通过自身携带的测速设备检测车辆1移动的速度。车载设备即为用户设备。
用户设备可以通过特定的APP以及无线通信方式来获取车载系统中传感设备发来的数据，所述传感设备上报的数据由用户设备进行分类，可以根据具体传感设备上报的信息类别来进行分类，可以由用户设备的分类机制(可由运营商提供)设定具体的分类方式，例如，传感器上报的信息为速度、加速、减速、刹车、转弯、报警、变道、故障、或者预警时，用户设备就将这些即时信息识别为局部信息，并用上述新增字段、设置目标地址信息、设置帧格式的方式将这些信息设置为局部信息，将其他信息如车身属性等识别为全局信息，并用上述新增字段、设置目标地址信息、设置帧格式的方式将全局信息与局部信息区别开来。用户设备的信息设置机制可以预先与基站进行匹配，以便于基站能够根据用户设备的信息设置方式识别出哪些信息是全局信息哪些是局部信息。
用户设备通过在上行信息中的第一信息中设置指示信息，用于使基站对上行信息进行分类，有效区分不同信息的时效性/即时性，使得基站能够根据指示信息区分出时效性/即时性较高的局部信息，并将局部信息以不经过核心网的传输方式尽快送达到其它用户设备，进而有效减少传输延时。
请参阅图5，图5为本发明实施例提供的一种通信方法的信息交互流程图。如图1-a或图1-b所示及相应描述，智能交通系统的组成以及基本的通信不再赘述。交互流程具体如下步骤：
步骤010：第一用户设备监控到行车位置、车速、车辆变道、车辆加速、车辆转弯、车辆刹车、车辆故障、路况不佳、出现突发事故或者自然灾害时， 这些交通信息在路况中直接影响着其他车辆的行车安全与行驶策略，因此具有很大的即时性，因此为了保证交通系统的安全和秩序井然，需要以更短的时间将这些信息传达到周边的车辆。这些即时性的信息就属于本发明中所提到的局部信息。另外第一用户设备还会上报给核心网一些第一用户设备所在车辆的基本情况，如机油寿命，轮胎压力，行驶里程等非即时性信息，这些信息就属于本发明中所提到的全局信息。第一用户设备将这些全局信息和局部信息可以打包在一起发送，也可以单独发送，这时第一用户设备就会生成上行信息，上行信息中可以包含很多的信息，为了方便说明，第一信息泛指上行信息中的一段子信息。
步骤020：第一用户设备在生成上行信息时，为了能够让基站能够准确地识别出上行信息中的哪些信息是全局信息哪些是局部信息，就需要利用自身的信息设置机制为第一信息设置出可以被判定的特征。
具体的可以通过在信息格式中新增字段，用不同的字段标识来区分全局信息和局部信息，包括但不限于字母、数字等。
具体的还可以在信息的目标地址字段中用不同的地址标记来区分全局信息和局部信息，包括但不仅限于地址代号、IP地址、邮箱地址等。
具体的还可以通过信息的帧格式来区分全局信息和局部信息，包括但不仅限用不同相位的载波来进行调制。
这些指示信息的相关描述，如上述实施例中所述，此处不再赘述。
步骤030：第一用户设备生成上行信息并对其中的第一信息进行加工完成后，即可上报给第一基站。
步骤040：第一基站接收第一用户设备上报的上行信息，并根据第一用户设备设置的指示信息来判定其中的第一信息是全局信息还是局部信息。若是局部信息则执行步骤050和070，若是全局信息则执行步骤060。
步骤050：第一基站判定第一信息为局部信息后，直接将第一信息发送至第三用户设备，为了方便说明，第三用户设备泛指第一基站覆盖的通信小区中的用户设备，并不限定个数与名称。与以往现有技术不同的是，第一基站无需上报核心网设备，省去了信息从“第一基站-核心网-第一基站”的传输时间，大大减少了局部信息的延时，使得对即时性要求很高的局部信息能够快速送达第一用户设备周边的用户设备中，能够很好地掌控、应对交通的突变状况，保证交通系统的安全性、可靠性以及稳定性。
本发明的实施例对基站向用户设备下发信息的方式不作限定，基站可以通过空口向本地的用户设备广播局部信息，本发明的实施例并不限于此，例如，基站也可以采用组播或单播方式向目标用户设备发送局部信息。
步骤060：第一基站判定第一信息为全局信息后，将第一信息发送给核心网设备，由核心网进一步进行处理，包括存储、备份、统计、分组、下发等。这些全局信息对实时性要求不高。
本发明的实施例对基站向核心网设备发送全局信息的方式不作限定。基站可以采用常规方式(例如，LTE系统中基站向核心网设备上传信息的方式)向核心网设备上传信息，例如，基站可以通过S1接口向核心网设备上传全局信息，本发明的实施例并不限于此，也可以使用其它常规的基站与核心网设备之间进行通信的方式。
步骤070：第一基站判定第一信息为局部信息后，还可以将第一信息发送至第二基站，为了方便说明，第二基站泛指在预置邻区列表中与第一基站相邻的基站，并不限定个数与名称。第一基站判定第一信息为局部信息后，可以对第一信息进行增加标签，标签可以使第二基站无需再对第一信息的指示字段、目标地址、帧格式等信息再进行解析判别，而是用更快的只识别标签的方式节省解析判别时间。
步骤080：第二基站接收到第一基站发送的第一信息，由于第二基站收到的信息千差万别，因此第二基站也需要判定第一信息是否是局部信息，判定方式既可以是根据第一用户设备设置的指示信息来判定其中的第一信息是全局信息还是局部信息，也可以是根据步骤070中第一基站增加的标签来判别。如果判定结果为第一信息是局部信息，直接将第一信息发送至第二用户设备，为了方便说明，第二用户设备泛指第二基站覆盖的通信小区中的用户设备，并不限定个数与名称。与以往现有技术不同的是，第一基站无需上报核心网设备，省去了信息从“第一基站-核心网-第二基站”或者“第二基站-核心网-第二基站”的传输时间，大大减少了局部信息的延时，使得对即时性要求很高的局部信息能够快速送达第二基站覆盖的小区内的第二用户设备，如此一来第一用户设备周边的用户设备都能够快速得到第一信息，整个区域的车辆都能因此作出恰当的决策，很好地掌控、应对交通的突变状况，保证交通系统的安全性、可靠性以及稳定性。
作为补充说明，上述步骤相互之间并非全部具有严格的先后时序。
作为可选的，当第一信息为局部信息时，第一基站可以将第一信息发送给核心网设备。
作为可选的，若第一基站接收到多个第一用户设备发送的上行信息且对应的多个第一信息都是局部信息时，第一基站可以按照预设规则对接收到的多个第一信息进行处理得到第一局部信息，再由第一基站将第一局部信息发送给至少一个第三用户设备或第二基站。
第一基站按照预设规则对接收到多个第一信息进行处理得到第一局部信息包括：若至少一个第一信息存在相同的内容，则将至少一个第一信息内容相同的部分进行合并，得到第一局部信息。根据预设的规则对多个第一信息进行处理可以用术语聚合来表示。例如，聚合也可以称为压缩，聚合局部信息可以指将至少一个第一信息内容相同的部分进行合并，从而减少或去除局部信息中的冗余信息的过程，用以提高资源的利用率和传输的效率。另外，聚合局部信息可以指对至少一个第一信息直接合并在一起发送，用以提高资源的利用率。第一基站可以分别将不同第一用户设备上传的信息下发给其它用户设备，也可以将不同第一用户设备的信息进行聚合后下发给其它用户设备，第一基站还可以将同一用户设备在不同时刻上传的信息进行聚合后下发给其它用户设备，或者将不同用户设备在相同时刻或不同时刻上传的信息进行聚合后，下发给其它用户设备。通过信息的聚合，可以减少信息传输的负荷，提高传输效率。
例如，假设用户设备A在T0时刻的速度为100km/h，T0+1，T0+2，T0+3，T0+4时刻的速度均为100km/h,那么用户设备A在时间段T0+1～T0+4中的信息聚合后，可以将局部信息设置为“0”，以表示T0+1～T0+4时刻与T0时刻相比，速度没有发生变化。
例如，用户设备A在T0时刻的速度为100km/h,用户设备B、C、D、E在T0时刻的速度也都是100km/h，那么不同设备在T0时刻的信息可以聚合为100km/h，即这些用户在T0时刻的速度均为100km/h。
再例如，不同用户设备A、B、C、D、E分别在T0～T0+4时刻上的速度信息可以聚合为100km/h。
由于上述几中聚合方式都能够去除局部信息中的冗余信息，减少了传输资源的占用，因此，能够提高传输效率。
作为补充说明，上行信息包括至少一个第一用户设备中的同一用户设备 发送的全局信息和局部信息，或者至少一个用户设备中的不同用户设备分别发送的全局信息和局部信息。具体而言，每个用户设备可以同时发送局部信息和全局信息中的至少一个，例如，可以是一个用户设备同时发送全局信息和局部信息，也可以是一个用户设备发送全局信息，另一个用户设备发送局部信息。
请参阅图6，图6是本发明一个实施例提供的基站800的结构示意图。
下面介绍两种基站。
一种基站800包括接收单元810、判断单元820和发送单元830。
接收单元810，用于接收第一用户设备发送的上行信息，上行信息中包含第一信息，第一信息中含有指示信息，指示信息用于指示第一信息为全局信息还是局部信息；其中，第一用户设备处于第一基站覆盖的通信小区；
判断单元820，用于根据所述接收单元810接收到的上行信息中的指示信息判断第一信息是全局信息还是局部信息；
发送单元830，用于若所述判断单元820判断第一信息为局部信息，则将第一信息发送给第二基站，其中，第二基站为预置临区列表中与第一基站具有相邻关系的基站；发送单元830还用于若判断单元820判断第一信息为全局信息，则将第一信息发送给核心网设备。
可选地，发送单元830还具体用于：若判断单元820判断第一信息为局部信息时，将第一信息发送给第三用户设备，其中第三用户设备处于第一基站所覆盖的通信小区。
可选地，作为另一实施例，若接收单元810接收到至少一个第一用户设备发送的上行信息且判断单元820判断出对应的至少一个第一信息都是局部信息时，基站还包括：
处理单元840，用于按照预设规则对接收到的至少一个第一信息进行处理得到第一局部信息，其中发送单元830将第一局部信息发送给至少一个第二用户设备。
根据本发明的实施例，若至少一个第一信息存在相同的内容，则处理单元840将至少一个第一信息内容相同的部分进行合并，得到第一局部信息。
另一种基站800包括接收单元810、判断单元820和发送单元830。

判断单元820，用于根据接收单元810接收到的上行信息中的指示信息判断第一信息是全局信息还是局部信息；
发送单元830，用于若判断单元820判断第一信息为局部信息时，则将第一信息发送给第二用户设备，其中第二用户设备处于上述另一种基站覆盖的通信小区。
可选地，作为另一实施例，若接收单元810接收到至少一个第一用户设备发送的上行信息且判断单元820判断出对应的至少一个第一信息都是局部信息时，所述另一种基站还包括：
处理单元840，用于按照预设规则对接收到的至少一个第一信息进行处理得到第一局部信息，其中发送单元830将第一局部信息发送给至少一个第二用户设备。

基站800的单元的操作和功能可以参考上述图2图3所对应的方法以及各种可能的实施方式，为了避免重复，在此不再赘述。
根据本发明的实施例，第一基站可以根据指示信息从用户设备发送的上行信息中识别全局信息和局部信息，若指示信息指示上行信息包含全局信息，向核心网设备上传全局信息，若指示信息指示上行信息包含局部信息，则直接向相邻基站发送局部信息，以便于相邻基站能够将局部信息下发至自自己覆盖的小区中的用户设备。由于局部信息无需再经过核心网转发，因此降低了局部信息的传输时延，从而降低了通信系统的时延。另外，在局部信息不经过核心网处理的情况下还能减轻核心网的负担。尤其在交通系统中，车辆在刹车、加速、减速时，能够将这些行驶状态信息通过本地基站和相邻基站快速地传送到周边的车辆，避免发生交通事故。

根据本发明的实施例，指示信息包括第一信息中增加的指示字段，指示字段包括第一标识或第二标识，第一标识用于指示第一信息为全局信息，第二标识用于指示第一信息为局部信息，第一标识与第二标识不同，其中设置单元920具体用于若第一信息为全局信息，则在指示字段中设置第一标识，若第一信息为局部信息，则在指示字段中设置第二标识。
可替代地，作为另一实施例，指示信息包括目标地址信息，其中，设置单元920具体用于若第一信息为全局信息，则在第一信息中设置用于指示第一信息的发送目标为核心网设备的目标地址信息，若第一信息为局部信息，则在第一信息中设置用于指示第一信息的发送目标为至少一个第二用户设备的目标地址信息。

如此一来，对于一种基站1000，收发器1030用于接收第一用户设备发送的上行信息，上行信息中包含第一信息，第一信息中含有指示信息，指示信息用于指示第一信息为全局信息还是局部信息。处理器1010用于根据上行信息中的指示信息判断第一信息是全局信息还是局部信息。收发器1040还用于若处理器1010判断第一信息为局部信息，则将第一信息发送给第二基站，其中，第二基站为预置临区列表中与基站1000具有相邻关系的基站。
如此一来，对于另一种基站1000，收发器1030用于接收第一基站发送的第一信息，第一信息中含有指示信息，指示信息用于指示第一信息是否为局部信息；其中第一基站为预置临区列表中与基站1000具有相邻关系的基站。处理器1010用于根据指示信息判断第一信息是全局信息还是局部信息。收发器1040还用于若处理器1010判断第一信息为局部信息，则将第一信息发送给第二用户设备，其中，第二用户设备处于基站1000覆盖的通信小区。
