Description

一种车联网传输资源调度方法及装置 技术领域
本发明涉及通信技术领域,尤其涉及一种车联网传输资源调度方法及装置。
背景技术
随着社会的不断发展,汽车的普及程度也越来越高,驾驶出行在给人们的出行带来便利的同时,也给人类社会带来一定负面影响,如城市交通拥堵、交通事故频发等,显然,建立完善的智能交通***(Intelligent Transportation System,ITS)是社会的发展需要。
目前,车辆可以通过车辆与车辆(Vehicle to Vehicle,V2V)之间通信或者车辆与交通基础设施(Vehicle to Infrastructure,V2I)之间通信来及时获取路况信息或接收信息服务,V2V以及V2I通信所使用的网络称为车联网。具体来说,车辆通过V2V通信,可以将自身的车速、行驶方向、具***置、是否踩了紧急刹车等行驶信息广播给周围车辆,而获取其它周围车辆的行驶信息的车辆驾驶员可以更好的感知视距外的交通状况,从而对危险状况做出提前预判以及避让。对于V2I通信,除了上述行驶信息的交互外,交通基础设施还可以为车辆提供各类服务信息和数据网络的支持,提高了交通智能化。
长期演技(Long Term Evolution,LTE)技术是目前主流的无线通信技术,具有良好的网络覆盖率,因此,将V2V和V2I通信与LTE技术相结合来提升车联网通信性能。由于LTE技术中分配传输资源的方式为中央控制方式,终端即车辆或交通基础设施的传输资源是通过基站统一调度配置的,避免了采用自由竞争的方式获取传输资源引起的多个终端竞争同一传输资源的资源碰撞问题,保证了业务的QoS。然而,在车联网中,无论V2V还是V2I通信,车辆都需要频繁的向周围车辆或交通基础设施发送行驶信息等信息,并接收其它车辆或交通基础设备发送的行驶信息等信息,然而,每次数据的发送都 需要将发送请求上报基站,通过基站分配传输资源,并将分配的传输资源通过信令通知终端,因此,车辆频繁进行数据传输会频繁与基站进行信令交互,增加了基站的信令开销,且基站也需要多次传输资源的分配,增加了基站的负载,降低了基站的工作效率。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
本发明实施例提供一种车联网传输资源调度方法及装置,用以解决现有技术中存在的通过基站调度方式获取传输资源导致的浪费基站的信令开销,并增加基站的负载,降低基站的工作效率的问题。其中,方法和装置是基于同一发明构思的,由于方法及装置解决问题的原理相似,因此装置与方法的实施可以相互参见,重复之处不再赘述。
在现有技术中,通过基站调度获取传输资源时,终端每次进行数据发送均需要上报基站进行传输资源的分配,并将分配的传输资源通过信令通知终端,显然,车辆频繁进行数据传输会频繁与基站进行信令交互,增加了基站的信令开销,且基站需要多次传输资源的分配,增加了基站的负载,降低了基站的工作效率;而采用本发明技术方案,通过终端接收并存储基站发送的宏网络***信息,并根据该宏网络***确定用于发送微网络***信息的节点传输资源,并根据该节点传输资源接收节点发送的微网络***信息,从而根据该微网络***信息接入微网络,在通信任务产生时,根据该通信任务确定 目标资源调度方式,根据确定的目标资源调度方式,确定在接入的微网络中的目标传输资源,最终基于该目标传输资源发送通信任务对应的数据,这样,终端在车联网***中进行通信任务数据传输时,可以自行确定目标传输资源,不需要与基站进行多个信令交互,减少了基站的信令开销,基站也不需要为终端发送数据分配传输资源,降低了基站的负载,提高了基站的工作效率。
本发明实施例提供了一种车联网传输资源调度方法及装置,适用于ITS中处理V2V和V2I上层业务数据通信的终端设备,如车辆、交通基础设施等终端,下面结合附图对本发明优选的实施方式进行详细说明。
本发明实施例提供的一种车联网传输资源调度方法可以但不限于使用LTE技术,还可以使用其他通信技术,在本发明实施例仅以使用LTE为例。
参阅图1所示,本发明提供的车联网传输资源调度方法的中车联网***包括基站、终端(车辆或交通基础设施等)以及节点,从网络结构来看,该车联网***包括基站控制的宏网络和节点控制的微网络。在本实施例中,将节点称为簇首。
由于基站的的工作频段较低,如2GHz,基站控制的宏网络一般网络覆盖面积较大,可选的,基站也可以使用和终端进行V2V和/或V2I通信所使用的频段相同,如5.9GHz。宏网络的功能为:为终端提供进行V2V和/或V2I通信所必须的***信息,以使终端可以根据该***信息搜索到以节点(即簇首)为控制节点的微网络;并在终端与微网络无法建立通信时,基站可以控制终端进行V2V和/或V2I通信。
节点控制的微网络的工作频段较高,如5.9GHz,因此,微网络的一般网络覆盖相对宏网络较小,如图所示,节点可以是静态节点,如小站(small cell)、路侧单元(Road-Side Units,RSU)、交通基础设备等,也可以是如车辆等的动态节点,还可以为基站本身。在微网络能够为终端进行V2V和/或V2I通信分配传输资源,降低终端与基站交互造成的信令开销,降低了基站的负载。
