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的一部分实施例,而不是全部实施例。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的前提下所获得的所有其他实施例,都应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:全球移动通讯(Global System of Mobile communication,简称“GSM”)系统、码分多址(Code Division Multiple Access,简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)系统、通用分组无线业务(General Packet Radio Service,简称“GPRS”)、长期演进(Long Term Evolution,简称“LTE”)系统、先进的长期演进(Advanced long term evolution,简称“LTE-A”)系统、通用移动通信系统(Universal Mobile Telecommunication System,简称“UMTS”)、未来5G通信系统等。
在一些实施例中,D2D通信可以指车对车(Vehicle to Vehicle,V2V) 通信,或V2X通信。在V2X通信中,X可以泛指任何具有无线接收和发送能力的设备,例如但不限于慢速移动的无线装置,快速移动的车载设备,或是具有无线发射接收能力的网络控制节点等,本发明对此不做限定。
应理解,本发明实施例主要应用于V2X通信的场景,但也可以应用于任意其它D2D通信场景,本发明实施例对此不做任何限定。
在V2X通信中存在两种通信方式,一种方式是设备间直接实现通信,称为基于PC5接口的通信;还有一种是基于现有的长期演进(Long Term Evolution,简称“LTE”)系统中空中接口(User Equipment to Universal,简称“UU接口”)的通信,在这种方式下,设备间的通信是通过基站中转实现的,即设备-基站-设备。在本发明实施例中,设备与设备之间是基于PC5接口进行信息交互的。当一个终端设备在PC5接口上发送需要其它终端设备转发的消息时,该终端设备需要附加上一定的转发条件,其它终端设备在转发该消息前需要判断其是否符合该转发条件,其他终端设备如果转发了此消息,这时也需要同时转发该消息所携带的转发条件。
图1是本发明实施例的一个应用场景的示意图。图1中以V2X通信的场景为例进行描述,但本发明实施例也可以应用于任意其它D2D通信场景,本发明对此不做限定。图1中示出了一个完整的D2D通信链路中参与信息传输的部分终端设备。其中,终端设备10向终端设备20、终端设备21和终端设备22发送消息,假设终端设备20满足转发条件,而终端设备21和终端设备22不满足转发条件,那么终端设备20转发该消息,例如可以向终端设备30、终端设备31和终端设备32转发该消息,而终端设备21和终端设备22则不对该消息进行转发。
图1中示出的不同的终端设备可以包括快速移动的车载设备例如终端设备10、终端设备20、终端设备22、终端设备30和终端设备31,或者是具有无线发射接收能力的网络控制节点例如终端设备21,或者是慢速移动的无线装置例如终端设备32。但是本发明实施例中对参与该D2D通信的终端设备的类型不作任何限定,该终端设备也可以是具有无线接收和发送能力的其他D2D设备。
图2是本发明实施例的D2D通信的方法的流程交互图。这里以终端设备10和终端设备20为例进行说明,但本发明实施例不限于此,本发明实施例中的通信方法中,终端设备10可以向包括终端设备20在内的多个终端设 备发送待转发信息,接收到还待转发信息的其他终端设备所执行的方法可以参考终端设备20所执行的方法。如图2所示,该D2D通信的方法包括:
201,终端设备10确定待转发信息,其中待转发信息包括目标信息和转发条件信息。
具体地,终端设备10确定需要转发给其他终端设备的待转发信息,该待转发信息中不仅包括目标信息,还包括用于指示该目标信息是否能够被继续转发的转发条件信息。可选地,该目标信息包括终端设备10的用户需求信息或者当前交通状况信息。如果其他终端设备例如终端设备20接收到该待转发信息,那么终端设备20就可以根据该待转发信息中的转发条件信息确定是否继续转发该待转发信息。如果该终端设备20不满足转发条件信息指示的转发条件,那么将不再对该待转发信息进行转发,如果该终端设备20满足该转发条件信息指示的转发条件,那么该终端设备20向其他终端设备继续转发该待转发信息,该待转发信息中包括该转发条件信息。
可选地,该转发条件信息包括位置条件信息和/或时间条件信息。
也就是说,上述转发条件信息所指示的转发条件,可以是基于地理位置的条件,也可以是基于时间的条件,还可以是同时基于地理位置和时间的条件。
在V2X通信的过程中,不管是交通信息还是终端设备之间的发现,都只有在一定的位置范围内才有意义。因此,终端设备10在PC5接口上发送需要其它终端设备转发的目标信息时,可以附加上该信息的有效的位置范围。只有在一定的地理位置范围内,该目标信息才是有效的,或者说该目标信息才有必要继续转发给其他设备。
可选地,该位置条件信息可以包括一下信息中的至少一种:需要转发所述待转发信息的终端设备的经度坐标范围、需要转发所述待转发信息的终端设备的纬度坐标范围、需要转发所述待转发信息的终端设备的高度坐标范围、需要转发所述待转发信息的终端设备与所述第一终端设备之间的最小距离,以及需要转发所述待转发信息的终端设备与所述第一终端设备之间的最大距离。
举例来说,假设该转发条件信息中包括需要转发所述待转发信息的终端设备的经度坐标范围,和需要转发所述待转发信息的终端设备的纬度坐标范围。并且终端设备10在行驶过程中遇到严重的交通拥堵,需要将该交通拥 堵的消息,即目标信息告诉给其他终端设备。假设发生该交通拥堵的区域范围为东经116°23′17〃、北纬39°54′59〃到东经116°30′18〃、北纬39°55′00〃的范围内,终端设备10需要通知地理位置位于东经116°23′15〃、北纬39°54′58〃到东经116°30′20〃、北纬39°55′01〃范围内的终端设备这里发生了该交通拥堵,那么该交通拥堵的信息中包括的转发条件信息就包括了该地理位置范围,因为该范围内的终端设备受该交通拥堵的影响较大,这些终端设备接收到该交通拥堵消息后可以调整自己的行车路线或者更换,以避免更加严重的交通拥堵和车流量较大引发的交通事故的发生。而对于位于该范围以外的其他终端设备,由于受该交通拥堵的影响较小,没有必要再将该交通拥堵消息转发给这些终端设备,以减少大量信息转发带来的网络拥塞,使该交通拥堵消息能够及时准确地被所需的终端设备所接收。
又例如,假设终端设备10向其他终端设备发送待转发信息,待转发信息包括的目标信息为指示当前所在区域发生交通拥堵的信息,待转发信息包括的该转发条件信息中包括需要转发所述待转发信息的终端设备与所述第一终端设备之间的最小距离Rmin,以及需要转发所述待转发信息的终端设备与所述第一终端设备之间的最大距离Rmax。终端设备10发送包括该转发条件信息的该待转发信息后,只有满足该转发条件信息指示的转发条件的终端设备,才将该待转发信息进行转发,即只有在距离终端设备10的距离为Rmin到Rmax范围内的终端设备才对该待转发信息进行转发,如果其中接收到该待转发信息的某个终端设备距离终端设备10的距离小于Rmin,或者其中接收到该待转发信息的某个终端设备距离终端设备10的距离大于Rmax,那么则不对该待转发信息进行转发。因为在V2X通信过程中,如果两个终端设备的距离很接近时,这样的转发是没有太大意义的,比如分别在同一条马路的两条车道上同向并列移动的两辆车,其有效覆盖范围可以认为基本上是一致的,可以避免这两辆车之间的不必要的转发以减少网络拥塞。而如果两个终端设备的距离很远时,一个终端设备所处的交通状况对另一个终端设备带来的影响是可以忽略的。
可选地,如果该转发条件信息中包括有需要转发所述待转发信息的终端设备与所述第一终端设备之间的最小距离和/或需要转发所述待转发信息的终端设备与所述第一终端设备之间的最大距离,终端设备10发送的待转发信息中还可以包括该终端设备10的位置信息,以便于其他终端设备接收到 该待转发信息后可以根据该位置信息确定与终端设备10之间的距离。
在V2X通信的过程中,某些信息可能是有时间限制的,譬如实时交通信息的传播。因此,终端设备10发送该目标信息时,可以附上该目标消息的有效时间范围一起发送。
可选地,该时间条件信息包括该待转发信息的发送时刻和最长转发时间,或者该时间条件信息包括该待转发信息的转发结束时刻。
其中,该发送时刻或转发结束时刻可以通过时间标记来表示,例如通过协调世界时(Universal Time Coordinated,简称“UTC”)的时标来表示,该最长转发时间可以是一个具体的时标,也可以是一个时间长度。
举例来说,终端设备10在行驶过程中遇到前方交警在处理一场交通纠纷,该交通纠纷处理时间在5分钟左右,那么终端设备10发送待转发信息,通知其他终端设备前方有五分钟的缓行,该待转发信息中不仅包括目标信息,即该交通纠纷的信息,还包括该时间信息5分钟和终端设备10发送该待转发信息的时刻信息例如14:00。其他终端设备接收到该待转发信息时,会根据转发条件信息来判断是继续进行转发,假设某个终端设备接收到该初始消息的时刻是14:02,那么根据转发条件信息能够确定14:02在14:00-14:05以内,表示该交通纠纷仍未处理完,那么继续将该待转发信息发送给其他的终端设备;如果某个终端设备接收到该待转发消息的时刻是14:07,那么根据转发条件信息能够确定14:07已经超过14:05以外,表示该交通纠纷已经处理完了,那么无需再将包括该转发条件的该待转发信息进行转发,以减少网络拥塞,使其他重要的信息能够及时被转发。
202,终端设备10发送该待转发信息。
具体地,终端设备10确定了需要发送的待转发信息后,发送该待转发信息,该待转发信息包括目标信息和用于指示该目标信息是否能够被继续转发的转发条件信息。
可选地,终端设备10通过广播的方式发送该待转发信息。
203,终端设备20接收终端设备10发送的待转发信息。
具体地,终端设备10发送该待转发信息后,终端设备20接收到终端设备10发送的该待转发信息,该待转发信息包括目标信息和转发条件信息。终端设备20根据该转发条件信息确定是否转发该待转发信息。
应理解,这里是以终端设备20接收到终端设备10发送的该待转发信息 为例进行说明,终端设备10发送的该待转发信息还可以由其他的终端设备接收到,其他终端设备接收到该待转发信息后,可以和终端设备20执行相同的方法,为了简洁,这里不再赘述。
可选地,该终端设备20接收终端设备10通过广播的方式发送的该待转发信息。
204,终端设备20根据该转发条件信息,确定是否转发该待转发信息。
具体而言,终端设备20从终端设备10接收到该待转发信息,该待转发信息包括目标信息和转发条件信息,终端设备20根据该待转发信息包括的转发条件信息,确定是否向其他终端设备转发该待转发信息。该转发条件信息可以包括位置条件信息和/或时间条件信息。如果终端设备20满足所述转发条件信息指示的转发条件,确定转发该待转发信息;如果终端设备20不满足所述转发条件信息指示的转发条件,禁止转发该待转发信息。应理解,该终端设备20如果根据该转发条件信息确定转发目标信息,那么在转发该目标信息的同时,也可以将该转发条件信息一并转发。
举例来说,如果该转发条件信息中包括需要转发所述待转发信息的终端设备与所述第一终端设备之间的最小距离,以及需要转发所述待转发信息的终端设备与所述第一终端设备之间的最大距离,终端设备20接收到待转发信息中还可以包括该终端设备10的位置信息。从而终端设备20可以根据终端设备10的位置信息和自身的位置,确定该终端设备20与终端设备10之间的距离是否满足该最小距离和该最大距离的要求,并确定是否转发该待转发信息。假设终端设备20接收到终端设备10发送的待转发信息,该待转发信息包括目标信息和转发条件信息,该目标信息指示终端设备10所在位置发生交通拥堵,该转发条件信息包括需要转发所述待转发信息的终端设备与所述第一终端设备之间的最小距离Rmin=500m和需要转发所述待转发信息的终端设备与所述第一终端设备之间的最大距离Rmax=5km。终端设备20还可以接收终端设备10发送的终端设备10的位置信息,例如终端设备10位于东经116°23′17〃、北纬39°54′59〃。终端设备20确定自身的位置为东经116°23′17〃、北纬39°56′62〃,那么终端设备20根据终端设备10的位置信息和终端设备20的位置信息计算出终端设备20与终端设备10之间的距离为R=2km,所以该终端设备20的位置大于该最小距离且小于该最大距离,该终端设备20需要转发该初始消息,同时转发终端设备20的位置信息,即 终端设备20位于东经116°23′17〃、北纬39°56′62〃的信息,以告知其他终端设备该拥堵消息,使其他终端设备接收到该交通拥堵消息后可以调整自己的行车路线或者更换交通工具。假设终端设备20确定自身的位置为东经116°23′17〃、北纬39°54′58〃,那么终端设备20根据终端设备10的位置信息和终端设备20的位置信息计算出终端设备20与第一终端设备10的距离为R=100m,所以该终端设备20的位置小于该最小距离,表示该终端设备20在距离终端设备10仅100m的位置,该终端设备20和该终端设备10的覆盖面积基本相同,为了减少不必要的转发信息,该终端设备20禁止转发该初始消息。假设终端设备20确定自身的位置为东经116°23′17〃、北纬39°52′62〃,那么终端设备20根据终端设备10的位置信息和终端设备20的位置信息确定终端设备20与第一终端设备10的距离为R=7km,所以该终端设备20的位置大于该最大距离,表示该终端设备20在距离终端设备7km开外的位置,已经远远超出当前的拥堵范围,受到该拥堵情况的影响已经很小了,该终端设备20没有必要再转发该初始消息。
因此,本发明实施例的D2D通信的方法,通过对进行信息转发的设备进行过滤,使符合一定条件的终端设备才能对待转发信息进行转发,从而避免了大量信息转发引起的拥塞。
在某些场景下,不仅转发信息,而且转发信息所包含的路径(拓扑结构)信息也都有用。例如V2X通信应用在交通事故救援,灾难救援等公共安全领域时,V2X信息的转发路径可能是非常有用的信息。终端设备10在PC5接口上发送需要转发的信息时,可以要求转发该信息的终端设备在进行信息转发时,同时附加上自己的属性信息一并发送。
可选地,如图3所示的本发明另一实施例的D2D通信的方法的流程交互图,在201中终端设备10确定的待转发信息,不仅包括目标信息和转发条件信息,还可以包括该终端设备10的属性信息和指示信息。在202中终端设备10发送该待转发信息。在203中终端设备20接收终端设备10发送该待转发信息时,不仅可以获取目标信息和转发条件信息,还可以获取终端设备10的属性信息和指示信息。其中,在该实施例中,该指示信息用于指示终端设备20在转发所述待转发信息时,同时发送终端设备20的属性信息。如果在204中,终端设备20根据待转发信息中包括的转发条件信息确定转发该待转发信息,该D2D通信的方法还可以包括2041、205和206。其中, 204可以被2041所替代。
205,终端设备20根据该指示信息确定转发信息。
终端设备20接收终端设备10发送的待转发信息,并根据该待转发信息中的指示信息确定转发信息,其中该转发信息包括待转发信息和终端设备20的属性信息。
可选地,该属性信息包括位置信息和以下信息中的至少一种:发送时刻信息、终端设备20的类型信息和终端设备20的身份信息。
其中,终端设备的类型信息指终端设备所属的类型,例如指示该终端设备是快速移动车载设备、慢速移动的无线装置,或者是具有无线发射接收能力的网络控制节点等。不同类型的终端设备可以用不同的类型标识来标记。
另外,终端设备的身份信息指每个终端各自具有的不同标识,例如在V2V通信过程中,每辆汽车的车牌号就可以当作各自的身份信息,知道了该终端设备的身份信息,就能够唯一地确定该终端设备。
具体而言,终端设备10发送待转发信息,该待转发信息包括目标信息、转发条件信息、该终端设备10的属性信息和指示信息。终端设备20接收到该待转发信息后,如果终端设备20根据其中的转发条件信息确定转发该待转发信息,那么终端设备20还会根据该指示信息确定转发信息,该转发信息不仅包括该待转发信息,还包括终端设备20的属性信息。
206,终端设备20发送该转发信息。
具体而言,终端设备20从终端设备10接收到终端设备10发送的待转发信息后,如果确定转发该待转发信息,终端设备20会根据该指示信息确定的转发信息,该转发信息中不仅包括该待转发信息,还包括终端设备20的属性信息。从而,接收到终端设备20发送的该转发信息的终端设备,可以从该转发信息中获取终端设备20的属性信息和终端设备10的属性信息,从而可以确定该待转发信息的传输路径,该传输路径包括参与转发所述待转发信息的终端设备的位置信息,根据从不同终端设备接收到的该待转发信息可以确定路径拓扑结构。这样,一个终端设备可以获得其他终端的位置及分布,在一些特殊的场景例如灾难救援现场可以对救援行动进行指导。
图4是本发明另一实施例的D2D通信的方法的流程交互图。这里以终端设备10和终端设备20为例进行说明,但本发明实施例不限于此,本发明实施例中的通信方法中,终端设备10可以向包括终端设备20在内的多个终 端设备发送该待转发信息,其他终端设备所执行的方法可以参考终端设备20所执行的方法。如图4所示,该D2D通信的方法包括:
401,终端设备10确定待转发信息。
具体地,终端设备10确定需要转发给其他终端设备的待转发信息,该待转发信息中包括目标信息、终端设备10的属性信息和指示信息。该指示信息用于指示终端设备20在转发该待转发信息时,同时发送终端设备20的属性信息。
可选地,该属性信息包括位置信息和以下信息中的至少一种:发送时刻信息、终端设备的类型信息和终端设备的身份信息。
402,终端设备10发送该待转发信息。
具体地,终端设备10确定了需要发送的待转发信息后,发送该待转发信息,该待转发信息包括目标信息、终端设备10的属性信息和指示信息。
可选地,终端设备10通过广播的方式发送该待转发信息。
403,终端设备20接收该待转发信息。
具体地,终端设备10发送该待转发信息后,终端设备20接收到终端设备10发送的该待转发信息,该待转发信息包括目标信息、终端设备10的属性信息和指示信息。终端设备20根据该指示信确定转发信息,该转发信息包括该待转发信息和终端设备20的属性信息。。
应理解,这里是以终端设备20接收到终端设备10发送的该待转发信息为例进行说明,终端设备10发送的该待转发信息还可以由其他的终端设备接收到,其他终端设备接收到该待转发信息后,可以和终端设备20执行下述相同的方法,为了简洁,这里不再赘述。
可选地,该终端设备20接收终端设备10通过广播的方式发送的该待转发信息。
404,终端设备20根据该指示信息确定转发信息。
具体而言,终端设备10发送待转发信息至终端设备20,该待转发信息包括目标信息、该终端设备10的属性信息和指示信息。终端设备20从终端设备10接收到该待转发信息后,终端设备20需要向其他终端设备发送该待转发信息。终端设备20根据该待转发信息包括的指示信息确定转发信息,该转发信息不仅包括该待转发信息,还包括终端设备20的属性信息。
405,终端设备20发送该转发信息。
具体而言,终端设备20从终端设备10接收到包括目标信息、终端设备10的属性信息和指示信息的待转发信息后,终端设备20会发送终端设备20根据该指示信息确定的转发信息,该转发信息中不仅包括该待转发信息,还包括终端设备20的属性信息。接收到该转发信息的终端设备可以从该转发信息中获取终端设备20的属性信息和终端设备10的属性信息,从而可以确定待转发信息的转发路径,根据从不同终端设备接收到的该待转发信息可以确定多条路径从而形成路径拓扑结构。
可选地,该方法还包括:
终端设备20根据待转发信息,确定该待转发信息的传输路径,该传输路径包括参与转发该待转发信息的终端设备的位置信息。
具体而言,终端设备20根据指示信息确定转发信息,该转发信息包括该待转发信息和该终端设备20的属性信息,并转发该转发信息。其他终端设备接收到终端设备20发送的转发信息后,可以获得终端设备10的位置信息和终端设备20的位置信息,也就是说,接收到该转发信息的终端设备可以确定该转发信息的传输路径。接收到该转发信息的终端设备还会接收到其他终端设备经过不同路径传输过来的该转发信息,同样也可获取该待转发信息的多个不同的路径信息,从而确定待转发信息被传输过程中的所有路径,可以形成一个路径拓扑结构。
这样,每个终端设备都可以获得其他终端的位置及分布,而且终端设备的类型信息可以区分终端设备的类型,从而在获得其他终端的位置及分布的同时,还可以获知每一个转发点处的设备是何种类型,以判断转发该信息的是车辆、行人还是其他,在一些特殊的场景例如灾难救援现场可以对救援行动进行指导。发送终端可以利用形成的该拓扑结构到达位于转发路径上的特定终端(转发路径上的转发终端),这样可以提高V2X通信中的转发效率(利用此拓扑结构,只要求位于转发路径上的特定终端转发),这在灾难救援和事故处理中是有特殊意义的。同时,基于转发路径中携带的地理位置信息也可以得出V2X中的车辆位置分布信息,这在公共安全领域(例如灾难救援,事故处理中)也是有帮助的。
可选地,该方法还包括:
终端设备20根据该待转发信息的多个传输路径,确定该多个传输路径上的参与转发该待转发信息的多个终端设备的位置分布情况。
举例来说,假设该属性信息包括位置信息,并且假设终端设备30接收到终端设备20发送的转发信息,那么终端设备30可以根据该路径拓扑结构获取每个车辆的具体位置,从而能够确定出哪个区域的车流量较为密集,哪个区域的车流量较为稀疏,以可以选择车流量较为稀疏的线路行驶,以避免更加严重的交通拥堵。
可选地,该方法还包括:
终端设备20在该待转发信息的多个传输路径中,确定目标传输路径;
终端设备20根据该目标传输路径,向所述第一终端设备发送反馈信息。
举例来说,假设该属性信息包括位置信息、时间信息和终端设备的身份信息,并且假设终端设备30接收到终端设备20发送的转发信息,那么终端设备30可以根据该转发信息确定待转发信息的传输路径,获取每个车辆的具体位置,以及从不同路径接收到该待转发信息所花费的时间。例如,终端设备10、终端设备20和终端设备30处于救灾现场,终端设备30从不同终端设备,经过不同路径接收到终端设备10发送的该待转发信息,该待转发信息指示终端设备10需要其他车辆的支援,假设终端设备30从终端设备20接收到终端设备10发送的该待转发信息所对应的这条路径上,该待转发信息传输所花费的时间最少,那么终端设备30如果自身有能力对终端设备10进行支援时,可以选择通过该路径,即终端设备30通过终端设备20向该终端设备10向所述第一终端设备发送反馈信息,从而在最短的时间内通知终端设备10,该反馈信息中可以包括终端设备30的身份信息、终端设备20的身份信息和终端设备10的身份信息,以使得该反馈信息按照终端设备的身份信息,通过这条指定路径进行传输最终到达终端设备10。
应理解,这里是以终端设备30接收到终端设备20发送的该转发信息为例进行说明,终端设备20发送的该转发信息还可以由其他的终端设备接收到,其他终端设备接收到该待转发信息后,可以和终端设备30执行相同的方法,为了简洁,这里不再赘述。
