Description

一种组通信方法、设备及系统 技术领域
本发明涉及通信领域,尤其涉及一种组通信方法、设备及系统。
背景技术
车联网作为一种新型车辆通信网络,能够实现车辆与车辆之间、车辆与路边基础设施之间的无线通信。在车联网中,假设车辆A需要发送的组通信数据的有效传输距离小于或等于320米,则车辆A可以通过长期演进(Long Term Evolution,LTE)网络向服务器发送该组通信数据,服务器使用广播或者组播的方式发送该组通信数据,这样与车辆A之间的距离小于或等于320米的车辆B会接收到该组通信数据。
为了保证道路上的所有车辆都能接收到相应的组通信数据,现有技术提供一种组通信方案,具体为:将在道路周边的基站提供服务的小区划分成若干个小区组,车辆A在驶入到一个小区组时,自动加入到该小区组,车辆A向服务器发送组通信数据后,服务器在该小区组包含的所有小区中广播该组通信数据,这样能够保证车辆A当前归属的小区内的车辆和车辆A的所有邻居小区内的车辆都可以接收到该组通信数据,同时,组通信数据也不会扩散到较远的小区。
但在实际应用中,小区的覆盖范围可能大于或小于320米。若小区的覆盖范围远大于320米,则服务器可能只需要在车辆A当前归属的小区中或者车辆A当前归属的小区中和车辆A的部分邻居小区中广播组通信数据,而采用现有方案,服务器是在车辆A当前归属的小区中和车辆A的所有邻居小区中广播组通信数据,这样就会造成下行传输资源的浪费。若小区的覆盖范围远小于320米,则服务器可能还需要在除车辆A当前归属的小区和车辆A的所有邻居小区之外的其他小区中广播组通信数据,而采用现有方案,除车辆A 当前归属的小区和车辆A的所有邻居小区之外的其他小区内的用户设备是无法接收到组通信数据的,即组通信数据没有得到有效传输,无法满足实际传输需求。
发明内容
本发明的实施例提供一种组通信方法、设备及系统,能够准确识别广播组通信数据的小区范围,并提高下行传输资源的利用率。
为达到上述目的,本发明的实施例采用如下技术方案:
本发明实施例提供一种组通信方法,服务器首先获取根据第一用户设备的位置信息确定的第一组标识,并获取第一用户设备发送的组通信数据,然后,该服务器根据第一组标识,在与第一组标识对应的小区中发送组通信数据。
由于本发明实施例中第一组标识是根据第一用户设备的位置信息确定的,因此采用本发明提供的组通信方法,能够准确的识别广播第一用户设备发送的组通信数据的小区范围,并提高下行传输资源的利用率。
可选的,若上述服务器为应用服务器,则服务器获取第一组标识的方法为:应用服务器根据其接收到的位置信息,从预设对应关系中,获取与位置信息对应的第一组标识,该位置信息为第一用户设备发送的位置信息,第一预设对应关系保存有位置信息与第一组标识之间的对应关系。
可选的,若上述服务器为应用服务器,则服务器获取第一组标识的方法为:应用服务器接收第一用户设备发送的第一组标识。
可以看出,若上述服务器为应用服务器,则应用服务器获取第一组标识的方法不唯一。
进一步地,若上述服务器为应用服务器,则应用服务器在第一广播会话中向广播服务器发送组通信数据,由广播服务器在小区中发送组通信数据,第一广播会话为应用服务器和广播服务器之间建立的与第一组标识对应的广播会话。
可选的,若上述服务器为广播服务器,则服务器获取第一组标 识的方法为:广播服务器接收应用服务器发送的第一组标识,或者,广播服务器接收基站发送的第一组标识,基站为第一用户设备的服务基站。
可以看出,若上述服务器为广播服务器,则广播服务器获取第一组标识的方法不唯一。
进一步地,若上述服务器为广播服务器,则广播服务器还接收应用服务器发送的业务标识,业务标识用于指示组通信数据的业务类型。
由于业务标识用于指示组通信数据的业务类型,因此,广播服务器可以根据该业务标识,可以获知应用服务器欲与该广播服务器进行哪一类型的组通信业务。
第二方面,本发明实施例提供一种组通信方法,用户设备获取第一信息,该第一信息为根据第一用户设备的位置信息确定的,该第一信息为用户设备的区域信息或第一组标识,然后,用户设备发送用户设备的区域信息或第一组标识。
用户设备在获取到该用户设备的区域信息或根据该用户设备的位置信息确定的第一组标识后,发送该用户设备的区域信息或根据该用户设备的位置信息确定的第一组标识,以便于组通信网络系统中的其他通信设备根据用户设备的区域信息确定第一组标识,或者组通信网络系统中的其他通信设备直接接收用户设备发送的第一组标识,进而使得其他通信设备在第一组标识对应的小区中发送组通信数据。由于用户设备的区域信息或第一组标识是根据第一用户设备的位置信息确定的,因此采用本发明提供的组通信方法,能够准确的识别广播第一用户设备发送的组通信数据的小区范围,并提高下行传输资源的利用率。
可选的,若第一信息为第一组标识,则用户设备获取第一信息的方法为:用户设备接收基站发送的第一组标识,基站为用户设备提供服务。
可选的,若第一信息为第一组标识,则用户设备获取第一信息 的方法为:用户设备接收基站发送的预设对应关系;用户设备获取自身的位置信息;用户设备根据位置信息,从预设对应关系中获取与位置信息对应的第一组标识,预设对应关系保存有位置信息与第一组标识之间的对应关系。
可以看出,本发明实施例中用户设备获取第一信息的方式不唯一。
进一步地,若第一信息为第一组标识,则用户设备向应用服务器发送第一组标识。
可选的,若第一信息为用户设备的区域信息,则用户设备获取第一信息的方法为:首先,用户设备接收基站发送的至少一个区域信息,基站为用户设备的服务基站,至少一个区域信息包括基站覆盖的区域,然后,用户设备获取用户设备的地理位置信息;最后,用户设备根据地理位置信息,将至少一个区域信息中地理位置信息所归属的区域信息作为用户设备的区域信息。
进一步地,若第一信息为用户设备的区域信息,则用户设备向基站发送用户设备的区域信息。
进一步地,本发明实施例提供的组通信方法中,用户设备还接收基站发送的配置信息,配置信息用于指示用户设备向基站发送用户设备的区域信息所采用的规则。
第三方面,本发明实施例提供一种组通信方法,基站接收第一用户设备发送的位置信息,并根据该位置信息确定第一组标识,然后,基站发送第一组标识。
由于本发明实施例中的第一组标识是根据第一用户设备的位置信息确定的,因此采用本发明提供的组通信方法,能够准确的识别广播第一用户设备发送的组通信数据的小区范围,并提高下行传输资源的利用率。
具体的,基站发送第一组标识的方法为:基站向第一用户设备发送第一组标识;或者,基站向广播服务器发送组标识信息,所述组标识信息包括所述第一组标识和所述第一用户设备的标识。
进一步地,所述组标识信息还包括业务标识,所述业务标识用 于指示所述第一用户设备发送的组通信数据的业务类型。
由于业务标识用于指示组通信数据的业务类型,因此,广播服务器可以该业务标识获知基站欲与该广播服务器进行哪一类型的组通信业务。
可选的,若位置信息为第一用户设备的区域信息,则在基站接收第一用户设备发送的位置信息之前,基站还向第一用户设备发送配置信息,配置信息用于指示第一用户设备向基站发送第一用户设备的区域信息所采用的规则。
第四方面,本发明实施例提供一种组通信方法,应用服务器向广播服务器发送组标识请求消息,组标识请求消息携带业务标识,业务标识用于指示组通信数据的业务类型,相应的,应用服务器接收广播服务器发送的组标识回复消息,组标识回复消息携带与业务标识对应的至少一个组标识以及与每个组标识对应的至少一个小区标识。
应用服务器向广播服务器发送的组标识请求消息携带有业务标识,因此,应用服务器可以按需获得与业务标识对应的至少一个组标识以及与每个组标识对应的至少一个小区标识,而不用获取其他业务类型的组标识,这样,可以降低应用服务器的接收能耗,减少应用服务器存储组标识的容量。
进一步地,本发明实施例中的应用服务器还获取第一用户设备发送的组通信数据和第一用户设备所归属的第一小区的小区标识,然后,应用服务器根据第一小区的小区标识,从至少一个组标识中确定与第一小区的小区标识对应的第一组标识。
进一步地,若组标识回复消息还携带与第一组标识对应的广播会话配置,则应用服务器在第一广播会话中向广播服务器发送组通信数据,第一广播会话为应用服务器和广播服务器之间建立的与第一组标识对应的广播会话。
可以理解的是,若组标识回复消息还携带与第一组标识对应的广播会话配置,则说明广播服务器已经建立了与第一组标识对应的 广播会话,因此,应用服务器可以直接在与第一组标识对应的广播会话中向广播服务器发送组通信数据。
第五方面,本发明实施例提供一种组通信方法,广播服务器接收应用服务器发送的组标识请求消息,组标识请求消息携带业务标识,业务标识用于指示组通信数据的业务类型,然后,广播服务器根据业务标识,向应用服务器发送组标识回复消息,组标识回复消息携带与业务标识对应的至少一个组标识以及与每个组标识对应的至少一个小区标识。
进一步地,若组标识回复消息还携带与第一组标识对应的广播会话配置,则广播服务器在第一广播会话中接收应用服务器发送的组通信数据,第一广播会话为应用服务器和广播服务器之间建立的与第一组标识对应的广播会话。
与上一实施例相对应,若组标识回复消息还携带与第一组标识对应的广播会话配置,则说明广播服务器已经建立了与第一组标识对应的广播会话,因此,应用服务器会直接在与第一组标识对应的广播会话中向广播服务器发送组通信数据,相对应的,广播服务器在该广播会话中接收应用服务器发送的组通信数据。
进一步地,广播服务器还向基站发送承载请求消息和组通信数据,承载请求消息携带第一组标识和业务标识,基站是为与第一组标识对应的小区提供服务的基站。
第六方面,本发明实施例提供一种组通信方法,基站接收广播服务器发送的承载请求消息,承载请求消息携带第一组标识和业务标识,并向该基站提供服务的的用户设备发送第一信令,第一信令携带第一组标识和业务标识,业务标识与第一组标识对应。
进一步地,基站接收广播服务器发送的与业务标识和第一组标识均对应的组通信数据,然后,基站向该基站提供服务的用户设备发送组通信数据。
容易理解的是,基站在接收到与第一组标识和业务标识均对应的组通信数据后,会根据第一组标识和业务标识,将该组通信数据 发送。
第七方面,本发明实施例提供一种组通信方法,归属于与第一组标识对应的小区的用户设备接收基站发送的第一信令,第一信令包括第一组标识和业务标识,业务标识与第一组标识对应。
具体的,用户设备接收基站发送的第一信令;然后,用户设备判断自身是否已经获得与第一组标识和业务标识均对应的配置,若该用户设备已获得与第一组标识和业务标识均对应的配置,则该用户设备接收基站发送的与第一组标识和业务标识均对应的组通信数据,若该用户设备未获得与第一组标识和业务标识均对应的配置,则用户设备向与第一组标识和业务标识均对应的应用服务器发送配置请求消息,以获得与业务标识和第一组标识均对应的广播会话配置,配置请求消息携带第一组标识和业务标识中的至少一个。
可以看出,用户设备只有在自身获得与第一组标识和业务标识均对应的广播会话配置后,才会接收基站发送的与所述业务标识和所述第一组标识均对应的组通信数据,因此,本发明实施例提供的组通信方法中用户设备不会接收其他业务类型的组通信数据,这样可以降低用户设备的接收能耗。

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详细地描述,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。
以下描述中,为了说明而不是为了限定,提出了诸如特定系统结构、接口、技术之类的具体细节,以便透切理解本发明。然而,本领域的技术人员应当清楚,在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中,省略对众所周知的移动设备、电路以及方法的详细说明,以免不必要的细节妨碍本发明的描述。
另外,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
当本发明实施例提及“第一”、“第二”等序数词时,除非根据上下文其确实表达顺序之意,否则应当理解为仅仅是起区分之用。
用户设备,是无线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如无线接入网(Radio Access Network,RAN))与一个或多个核心网进行通信。无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,无线终端也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。无线终端还可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote station)、接入点 (Access point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、或用户装备(User Equipment)。
本文中描述的各种技术可用于各种广播系统中,例如全球移动通信系统(Global System for Mobile Communications,GSM),码分多址(Code Division Multiple Access,CDMA)2000系统,宽带码分多址(Wideband Code Division Multiple Access Wireless,WCDMA),LTE系统,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)定义的基于LTE系统的紧急对讲(Mission critical Push to talk,MCPTT)系统,车辆对车辆(Vehicle to Vehicle,V2V)系统以及其他此类通信系统。
LTE的组通信使能(Group Communication System Enablers,GCSE)技术是在3GPP中引入了应用层的功能来支持组通信的技术。LTE中的每个用户设备可以属于一个小区组或者多个不同的小区组。
图1是LTE系统架构中组通信系统的网络结构图。参见图1,该网络系统中包括组通信业务应用服务器(Group Communication Service Application Server,GCS AS)100、分组数据网关(Packet Data Network,PDN GW)101、广播多播业务中心(Broadcast-Multicast Service Centre,BM-SC)102、演进型基站(evolved Node B,eNB)103以及用户设备(User Equipment,UE)104。其中,GCS AS 100与PDN GW 101之间通过网络连接,GCS AS 100与BM-SC 102之间通过网络接口(例如LTE系统中的MB2接口)连接。GCS AS 100可以使用LTE单播演进型分组系统进行业务传输,也可以使用现有的MBMS网络广播组通信业务。图1中实线表示GCS AS 100使用LTE单播演进型分组系统进行业务传输,虚线表示GCS AS 100使用现有的MBMS网络广播组通信业务。
结合图1,图2为LTE系统架构中组通信系统的结构组成示意图。其中,演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN)是无线接入网络,其包括为UE 104 提供接入无线网络接口的eNB 103。BM-SC 102提供业务的汇聚和发送、用户的授权、MBMS业务承载的建立和发起、会话控制的发起等,同时还可以实现BM-SC 102与eNB 103之间的同步,其负责处理用户数据相关的报文和会话相关的信令。Uu,M1,M3,SGi,GC1,MB2均表示接口。UE 104通过应用层的GC1接口和GCS AS 100建立连接,并通过GC1接口向GCS AS 100发送组通信数据。由于UE 104会提前加入至一个或多个小区组中,因此,GCS AS 100在接收UE 104发送的第一信息(第一信息与UE 104所归属的小区组的组标识存在映射关系,例如第一信息可以为小区ID)和组通信数据后,GCS AS100根据第一信息即可获知其接收到的组通信数据来自哪个小区组。其中,小区组的组标识可以为TMGI。
上述组通信系统中,在下行的过程中,GCS AS 100与BM-SC 102预先建立很多广播会话,每个广播会话对应着一个TMGI和广播会话流标识。这样,当GCS AS 100接收到第一信息和组通信数据后,就会自动地在第一广播会话中发送该组通信数据,第一广播会话与TMGI1对应,TMGI1与第一信息对应。
在车联网中,组通信数据的有效传输距离小于或等于320米。为了保证道路上的所有的车辆都能接收到其相应的组通信,现有技术提供一种组通信方案,具体为:将在道路周边的基站提供服务的小区划分成若干个小区组,这样,车辆A在驶入到一个小区组后,自动加入到该小区组,车辆A向服务器发送组通信数据后,服务器在该小区组包含的所有小区中广播该组通信数据。
如图3所示,在沿着道路的5个基站中,将eNB1、eNB2和eNB3划分为小区组1,eNB2、eNB3和eNB4划分为小区组2,eNB3、eNB4和eNB5划分为小区组3。车辆A在进入小区组2且在小区3(eNB3提供服务的小区)向服务器发送组通信数据后,服务器在小区2(eNB2提供服务的小区)、小区3和小区4(eNB4提供服务的小区)中广播组通信数据。
在基于用户设备划分小区组的场景中,采用上述方法传输组通 信数据可以满足实际需求,但是在基于位置划分小区组的场景,采用上述方法传输组通信数据会出现资源浪费或者组通信数据没有有效传输的问题。
具体的,若组通信系统是使用宏基站部署的,小区半径远大于320米,则服务器可能只需要在用户设备当前归属小区或者用户设备当前归属小区和用户设备的部分邻居小区内广播组通信数据,而不会在用户设备当前归属小区用户设备的所有邻居小区内广播组通信数据。
如图4所示,按照现有小区组的划分方法,eNB1、eNB2和eNB3划分为小区组1,位于小区2(eNB2提供服务的小区)的车辆A向服务器发送V2V数据。若采用现有的方法传输V2V数据,则服务器会在小区组1(eNB1提供服务的小区1、小区2和eNB3提供服务的小区3)中广播V2V数据。但是,由于V2V数据的有效传输距离最大为320米(图中用虚线框表示以车辆A为中心,半径为320米的区域),因此,小区3的所有车辆都不需要接收该V2V数据。图中V2V数据只需要在小区1和小区2中广播即可。这样,采用现有的方法传输V2V数据,就会浪费小区3的下行传输资源。
具体的,若组通信系统是使用微基站部署的,小区半径小于320米,则服务器可能还需要在除用户设备当前归属小区和用户设备的所有邻居小区之外的其他小区内广播组通信数据。
如图5所示,按照现有小区组的划分方法,eNB1、eNB2和eNB3划分为小区组1,位于小区2(eNB2提供服务的小区)的车辆A向服务器发送V2V数据。若采用现有的方法传输V2V数据,则服务器会在小区组1(eNB1提供服务的小区1、小区2和eNB3提供服务的小区3)中广播V2V数据。但是,V2V数据的有效传输距离最大为320米,图中用虚线框表示以车辆A为中心,半径为320米的覆盖区域,该覆盖范围包括小区1、小区2、小区3和小区4(eNB4提供服务的小区),因此,位于小区4内的车辆也需要接收该V2V数据。而采用现有的方法传输V2V数据,位于小区4内的车辆无法接收到 该V2V数据。这样,采用现有的方法传输V2V数据,就会导致V2V数据没有得到有效传输。
本发明实施例提供一种组通信方法、设备及系统,服务器获取根据第一用户设备的位置信息确定的第一组标识,并获取第一用户设备发送的组通信数据,然后,服务器根据第一组标识,在与第一组标识对应的小区中发送组通信数据。由于本发明实施例中第一组标识是根据第一用户设备的位置信息确定的,因此采用本发明提供的组通信方法,能够准确的识别广播第一用户设备发送的组通信数据的小区范围,并提高下行传输资源的利用率。
本发明实施例提供的组通信方法和设备可应用于类似于图2和图3所示的组通信系统,适用于基于用户设备的地理位置划分小区组的组通信业务。
本发明实施例中的服务器为应用服务器或广播服务器。为了方便理解,本发明下述实施例中以服务器为应用服务器或广播服务器为例进行说明。
其中,本发明实施例中的应用服务器可以为LTE系统中的GCS AS,也可以为V2V通信系统中的V2V应用服务器,本发明实施例对此不作具体限定。
V2V通信技术是指在V2V无线网络中汽车之间互相传送自身的状态信息(例如:速度、位置、驾驶方向、刹车等)的技术。
本发明实施例提供一种组通信方法,如图6所示,包括:
S100、应用服务器与广播服务器协商,预先建立与所有小区组的组标识对应的广播会话。
S101、第一用户设备接入组通信网络,并建立第一用户设备与应用服务器之间应用层的连接。
S102、第一用户设备向应用服务器发送第一用户设备的位置信息。
S103、应用服务器根据第一用户设备的位置信息,从预设对应 关系中,获取与第一用户设备的位置信息对应的第一组标识。
其中,预设对应关系保存有至少一个位置信息,以及与每个位置信息对应的组标识。

S105、应用服务器在与第一组标识对应的广播会话中向广播服务器发送组通信数据。
S106、广播服务器在与第一组标识对应的小区中发送组通信数据。
第一用户设备接入组通信网络的过程中,第一用户设备可以根据其所处位置加入多个小区组,也可以是整个组通信网络中只配置一个小区组,该第一用户设备加入该小区组。
具体的,第一用户设备与为其提供服务的基站之间建立网络承载,该网络承载用于传输组通信数据。
可选的,第一用户设备在接入组通信网络中时,第一用户设备接收应用服务器发送的配置信息,该配置信息用于指示第一用户设备向应用服务器发送第一用户设备的位置信息所采用的规则。
其中,第一用户设备的位置信息为第一用户设备的地理位置信息或者第一用户设备的区域信息。
具体的,第一用户设备的地理位置信息可以为用经纬度坐标来表示的二维地理位置信息。
示例性的,第一用户设备的当前地理位置信息为B地,若B地的经纬度坐标为(x,y)。
可选的,本发明实施例中,组通信网络系统中的各个节点(包括用户设备、基站、应用服务器以及广播服务器)根据预先约定的区域划分规则,将经纬度网格划分成多个区域,每个区域的信息不同,则第一用户设备的区域信息是指第一用户设备根据预先约定的区域划分规则,确定出第一用户设备的区域信息。
可选的,本发明实施例中,组通信网络系统中的基站按照某一区域划分规则将组通信网络系统中至少一个小区的覆盖范围划分为 至少一个区域,每个区域的信息不同,基站向第一用户设备发送至少一个区域信息,第一用户设备获取自身的位置信息,并将至少一个区域信息中自身的位置信息所归属的区域信息作为第一用户设备的区域信息。其中,在这种应用场景中,应用服务器和广播服务器可预先与基站交互,以获知至少一个区域信息。
其中,本发明实施例中的区域信息包括该区域范围的边界点的经纬度信息或者该区域的中心点的经纬度信息以及该区域的区域半径。
具体的,应用服务器向第一用户设备发送的配置信息为第一用户设备的位置信息的上报周期、第一用户设备的位置信息的上报格式和第一用户设备的位置信息的上报触发条件中的至少一个。
其中,第一用户设备的位置信息的上报格式可以为完整的位置信息,也可以为满足某一精度的位置信息。
第一用户设备的位置信息的上报触发条件可以为下述任意一种:
1、若当前时刻满足上报周期的配置,则第一用户设备在当前时刻向应用服务器发送第一用户设备的位置信息。
2、若第一用户设备的当前位置信息与第一用户设备上次向应用服务器发送的位置信息之间的距离大于或等于某一预设阈值,则第一用户设备向应用服务器发送第一用户设备的当前位置信息。
3、若第一用户设备的区域信息发生变化,则第一用户设备向应用服务器发送第一用户设备当前的区域信息。
第一用户设备在接入组通信网络后,向应用服务器发送自身的位置信息,即第一用户设备执行S102。
具体的,第一用户设备首先获取自身的位置信息。
若第一用户设备的位置信息为第一用户设备的地理位置信息,则第一用户设备可以采用现有的任意一种定位技术获取第一用户设备的地理位置信息。
示例性的,第一用户设备具备定位功能,则第一用户设备采用 卫星定位技术确定自身的地理位置信息,或者采用惯性导航技术确定自身的地理位置信息。
若第一用户设备的位置信息为第一用户设备的区域信息,则第一用户设备首先确定自身的地理位置信息,然后,第一用户设备利用自身的地理位置信息,根据预先约定的区域划分规则或者从基站获得的至少一个区域信息,确定第一用户设备的区域信息。其中,第一用户设备确定自身的地理位置信息的方法可以参考上述描述,此处不再进行详细赘述。
具体的,第一用户设备在获取到自身的位置信息后,向应用服务器发送自身的位置信息。
其中,在车联网中,第一用户设备可以将其位置信息携带在CAM(Cooperative Awareness Message,联合感知消息)中,向V2V应用服务器发送。
若第一用户设备的位置信息为第一用户设备的区域信息,则第一用户设备向应用服务器发送区域信息的方法可以为以下两种方法中的任意一种:
1、第一用户设备首先确定第一用户设备当前的区域信息,然后,第一用户设备判断自身当前的区域信息与第一用户设备上次向应用服务器发送的区域信息是否相同;若不同,则第一用户设备向应用服务器发送第一用户设备当前的区域信息。
2、第一用户设备确定第一用户设备当前的区域信息,并向应用服务器发送第一用户设备当前的区域信息。
进一步地,若第一用户设备在接入组通信网络后,还接收到应用服务器发送的配置信息,则第一用户设备采用该配置信息指示的规则,向应用服务器发送自身的位置信息。
具体的,若第一用户设备接收到的配置信息包含有第一用户设备的位置信息的上报触发条件,则第一用户设备根据该上报触发条件向应用服务器发送其位置信息。
需要说明的是,为了防止在通信过程中出现不必要的错误,第 一用户设备向应用服务器发送位置信息时,还发送第一用户设备的标识。
具体的,应用服务器在接收到第一用户设备发送的位置信息之后,该应用服务器根据第一用户设备的位置信息,从预设对应关系中,获取与第一用户设备的位置信息对应的第一组标识,即执行S103。
其中,预设对应关系保存有至少一个位置信息,以及与每个位置信息对应的组标识。至少一个位置信息可以是至少一个地理位置信息,也可以是每个广播会话对应的区域信息。
可以理解的是,预设对应关系保存有第一用户设备的位置信息与第一组标识之间的对应关系。
具体的,若预设对应关系中保存有至少一个地理位置信息以及与每个地理位置信息对应的组标识,则应用服务器在接收到第一用户设备的地理位置信息后,应用服务器根据第一用户设备的地理位置信息,能够从该预设对应关系中获取到与第一用户设备的地理位置信息相对应的第一组标识。
同理,若预设对应关系中保存有至少一个区域信息以及与每个区域信息对应的组标识,则应用服务器在接收到第一用户设备的区域信息后,应用服务器根据第一用户设备的区域信息,能够从该预设对应关系中获取到与第一用户设备的区域信息相对应的第一组标识。
可选的,本发明实施例中第一组标识可以为应用层组标识,也可以为通信层组标识,还可以为第一组标识指示的第一小区组所包含的至少一个小区的小区标识,还可以为与第一组标识对应的广播会话流标识等。
优选的,通信层组标识为TMGI。
需要说明的是,本发明实施例中广播会话流标识与目前GCSE技术的流标识Flow ID是不同的。
GCSE技术的Flow ID用于区分在同一个小区组的不同广播服务器控制区域,同一小区组对应的不同的Flow ID,其对应的广播会 话区域一定是不重叠的,且一定位于不同的广播服务器的控制范围下。
而本发明实施例中广播会话流标识是区分在同一个小区组对应的区域中,某一个特定的小区集合所对应的区域。在应用服务器与广播服务器建立广播会话连接时,使用广播会话流标识建立一个广播会话,该广播会话对应一个下行广播/组播小区列表,且这些小区可以位于不同广播服务器的控制范围内。
此外,第一小区组可以包含一个小区,也可以包含至少两个小区,因此,第一小区组可以用该小区组包含的至少一个小区的小区标识表示。具体的,若第一小区组仅包含一个小区(小区A),则第一小区组可以用小区A表示。若第一小区组包含三个小区(小区A、小区B和小区C),则第一小区组可以用包含有小区A、小区B和小区C的小区列表表示。
具体的,若预设对应关系保存有至少一个位置信息以及与每个位置信息对应的至少一个小区标识,则应用服务器在获取到第一用户设备的位置信息后,根据第一用户设备的位置信息,从预设对应关系中获取与第一用户设备的位置信息对应的至少一个小区标识。
进一步地,应用服务器还根据与第一用户设备的位置信息对应的至少一个小区标识,从预先建立的所有小区组的组标识对应的广播会话中,确定发送组通信数据的广播会话流标识。
具体的,应用服务器在接收到第一用户设备发送的组通信数据之后,应用服务器在与第一组标识对应的广播会话中向广播服务器发送组通信数据,由广播服务器在与第一组标识对应的小区中发送组通信数据,即执行S104-S106。
其中,S104-S106与现有技术相同,本发明实施例对此不再进行详细赘述。
可选的,本发明实施例中第一用户设备可以先执行S102,后执行S104,也可以为先执行S104,后执行S102,还可以同时执行S102和S104,本发明实施例对此不作具体限定。
可以理解的是,为了防止在通信过程中出现不必要的错误,第一用户设备向应用服务器发送组通信数据时,还发送第一用户设备的标识。
可选的,若本发明实施例中的第一用户设备是根据基站发送的至少一个区域信息来确定第一用户设备的区域信息,则在第一用户设备向应用服务器发送第一用户设备的位置信息之前,第一用户设备还接收基站发送的至少一个区域信息。
具体的,如图6所示,本发明实施例提供的组通信方法在S102之前,还可以包括S107。
S107、基站向第一用户设备发送至少一个区域信息。
其中,基站可以通过系统消息向第一用户设备发送至少一个区域信息,也可以通过RRC(Radio Resource Control,无线资源控制)消息向第一用户设备发送至少一个区域信息,本发明实施例对此不作具体限定。
由于S107为可选步骤,因此,图6中S107用虚线表示。
本发明实施例中,应用服务器根据第一用户设备发送的位置信息,确定出第一组标识,以在与第一组标识对应的小区中发送第一用户设备发送的组通信数据。由于第一组标识是根据第一用户设备的位置信息确定的,因此,与第一组标识对应的小区能够满足组通信数据对传输距离的要求,即本发明实施例提供的组通信方法,能够准确的识别广播第一用户设备发送的组通信数据的小区范围,并提高下行传输资源的利用率。
本发明另一实施例提供一种组通信方法,如图7所示,包括:
S200、应用服务器与广播服务器协商,预先建立与所有小区组的组标识对应的广播会话。
S201、第一用户设备接入通信网络,并建立第一用户设备与应用服务器之间应用层的连接。
S202、第一用户设备向基站发送第一用户设备的位置信息。
S203、基站根据第一用户设备的位置信息,从预设对应关系中,获取与第一用户设备的位置信息对应的第一组标识。
S204、基站向广播服务器发送第一组标识和第一用户设备的标识。
S205、第一用户设备向应用服务器发送组通信数据。
S206、应用服务器向广播服务器发送组通信数据和第一用户设备的标识。
S207、广播服务器根据其接收的与第一用户设备对应的第一组标识,向与第一组标识对应的小区发送第一用户设备的组通信数据。
本发明实施例中的S200与上一实施例中的S100相同,S207与上一实施例中的S106相同,此处不再赘述。
与上一实施例不同的是,本发明实施例中第一用户设备在接入组通信网络,即第一用户设备执行S201时,第一用户设备接收基站发送的配置信息,该配置信息用于指示第一用户设备向基站发送第一用户设备的位置信息所采用的规则。
本发明实施例中,关于配置信息的具体定义和第一用户设备的位置信息可以参考上述实施例,此处不再进行详细赘述。
其中,本发明实施例中第一用户设备可以通过系统消息接收基站发送的配置信息,也可以通过RRC消息接收基站发送的配置信息,本发明实施例对此不作具体限定。
本发明实施例中的第一用户设备获取自身的位置信息的方法与上一实施例中第一用户设备获取自身的位置信息的方法相同,此处不再进行详细赘述。
可选的,在第一用户设备建立其与应用服务器之间的应用层的连接过程中,第一用户设备向应用服务器发送业务标识,该业务标识用于表示组通信数据的业务类型。示例性的,业务标识用于表示车联网中的V2V业务或V2I业务。
具体的,本发明实施例中第一用户设备在获取到自身的位置信息后,向基站发送其位置信息,即第一用户设备执行S202。
本发明实施例中第一用户设备向基站发送第一用户设备的位置信息的方法可以参考上一实施例中第一用户设备向应用服务器发送第一用户设备的位置信息的方法,此处不再进行详细赘述。
不同的是,上一实施例中第一用户设备是向应用服务器发送第一用户设备的位置信息,而本发明实施例中第一用户设备是向基站发送第一用户设备的位置信息。
同理,本发明实施例中第一用户设备向基站发送第一用户设备的位置信息时,还发送第一用户设备的标识。
基站在接收到第一用户设备发送的位置信息后,根据第一用户设备的位置信息,从预设对应关系中,获取与第一用户设备的位置信息对应的第一组标识,即执行S203。
本发明实施例中预设对应关系保存的信息与上一实施例中预设对应关系保存的信息相同,区别只是本发明实施例中的预设对应关系存储于基站中,上一实施例中的预设对应关系存储于应用服务器中。
具体的,基站在确定出第一组标识后,通过组通信网络向广播服务器发送第一组标识。
需要说明的是,为了防止在通信过程中出现不必要的错误,基站在向广播服务器发送第一组标识的同时,还需要发送第一用户设备的标识。简单的说,基站向广播服务器发送第一组标识和第一用户设备的标识,即S204。
其中,基站可以通过第一信令通道向广播服务器发送第一组标识和第一用户设备的标识,第一信令通道包括基站与MCE(Multi-cell/multicast Coordination Entity,多小区多播协调实体)之间的信令通道、MCE与MME(Mobility Management Entity,移动性管理实体)之间的信令通道、MME与MBM-GW(Multimedia Broadcast Multicast Service gateway,多媒体广播多播服务器网关)之间的信令通道以及MBM-GW与广播服务器之间的信令通道。
基站还可以通过第二信令通道向广播服务器发送第一组标识和 第一用户设备的标识,第二信令通道包括基站与S-GW(service gateway,服务网关)之间的信令通道、S-GW与P-GW(pacekt data network gateway,数据包网络网关)之间的信令通道以及P-GW与广播服务器之间的信令通道。
可选的,基站向广播服务器发送第一组标识和第一用户设备的标识时,基站还可以向广播服务器发送第一组标识的有效期。这样,在时间超过有效期后,广播服务器不再利用第一组标识发送组通信数据,保证了广播组通信数据的有效性。
可选的,基站向广播服务器发送第一组标识和第一用户设备的标识时,还可以向广播服务器发送业务标识。
示例性的,业务标识用于表示车联网业务,广播服务器在接收到携带有表示车联网业务的业务标识和第一组标识后,广播服务器即可根据业务标识获知与第一组标识对应的小区可用车联网业务。
同理,上述S205中第一用户设备向应用服务器发送组通信数据时,第一用户设备还向应用服务器发送第一用户设备的标识。进一步地,应用服务器向广播服务器发送组通信数据和第一用户设备的标识,即执行S206。
对应的,广播服务器接收应用服务器发送的组通信数据和第一用户设备的标识后,广播服务器根据第一用户设备的标识即可获知需要向与第一组标识对应的小区发送组通信数据。
具体的,若在第一用户设备接入通信网络的过程中,应用服务器接收到第一用户设备发送的业务标识,则应用服务器在获取到组通信数据后,应用服务器在与业务标识对应的广播会话中向广播服务器发送组通信数据和第一用户设备的标识。广播服务器通过该广播会话可获知组通信数据所归属的业务类型。
具体的,广播服务器根据其最后一次接收的与第一用户设备对应的第一组标识,向与第一组标识对应的小区发送组通信数据。
需要说明的是,本发明实施例中第一用户设备可以在其接入组通信网络中之后的任一时刻向应用服务器发送组通信数据,即S205 可以在S201之后的任一时刻执行。
可选的,若本发明实施例中的第一用户设备的位置信息是第一用户设备的区域信息,且第一用户设备的区域信息是第一用户设备根据基站发送的至少一个区域信息来确定的,则在第一用户设备向基站发送第一用户设备的区域信息之前,第一用户设备还接收基站发送的至少一个区域信息。
如图7所示,本发明实施例提供的组通信方法在S202之前,还可以包括S208。
S208、基站向第一用户设备发送至少一个区域信息。
由于S208为可选步骤,因此,图7中S208用虚线表示。
本发明实施例中的S208与上一实施例中的S107相同,此处不再进行详细赘述。
与上一实施例相比较,本发明实施例中通过基站确定第一组标识的方式,减少了核心网的部署成本和计算的复杂度。
本发明另一实施例提供一种组通信方法,如图8所示,包括:

进一步地,第一用户设备在获取到第一组标识后,向应用服务器发送第一组标识和组通信数据。
其中,本发明实施例中第一用户设备向应用服务器发送第一组标识的方法可以为以下两种方法中的任意一种:
1、第一用户设备首先确定与第一用户设备当前的区域信息相对应的第一组标识,然后,第一用户设备判断第一组标识与第一用户设备上次向应用服务器发送的组标识是否相同;若不同,则第一用户设备向应用服务器发送第一组标识。
2、第一用户设备确定与第一用户设备当前的区域信息相对应的第一组标识,并向应用服务器发送第一组标识。

其中,第一小区为第一用户设备所归属的小区。
S504、应用服务器根据第一小区的小区标识,从至少一个组标识中确定与第一小区的小区标识对应的第一组标识。
S505、应用服务器判断组标识回复消息是否携带与第一组标识 对应的广播会话配置。
S506、若组标识分配回复消息未携带与第一组标识对应的广播会话配置,则应用服务器向广播服务器发送广播会话激活请求消息。
其中,广播会话激活请求消息携带第一组标识。
示例性的,广播会话激活请求消息为LTE系统中的MBMS会话激活请求(Activate MBMS Bearer Request)消息。
S507、若组标识分配回复消息携带有与第一组标识对应的广播会话配置,则应用服务器在第一广播会话中向广播服务器发送组通信数据。
其中,第一广播会话为所应用服务器和广播服务器之间建立的与第一组标识对应的广播会话。
可选的,本发明实施例中的广播服务器在执行S502之前,所述广播服务器还根据业务标识,建立至少一个用于传输组通信数据的广播会话。
具体的,结合图10,如图11所示,本发明实施例提供的组通信方法在S502之前还包括:
S508、广播服务器根据业务标识,在至少一个小区标识指示的至少一个小区和广播服务器之间建立会话。
进一步地,如图11所示,广播服务器在至少一个小区标识指示的至少一个小区和广播服务器之间建立会话,且在第一广播会话中接收应用服务器发送的组通信数据之后,本发明实施例提供的组通信方法还包括:

其中,本发明实施例中基站向该基站提供服务的用户设备发送 的第一组标识和业务标识可以承载于同一字段,也可以承载于不同字段,本发明实施例对此不做具体限定。
S512、第二用户设备识别业务标识,并判断自身是否已经获得与第一组标识和业务标识均对应的配置。
其中,第二用户设备为基站提供服务的其中一个用户设备。
S512、若第二用户设备未获得与第一组标识和业务标识均对应的配置,则第二用户设备向与第一组标识和业务标识均对应的应用服务器发送配置请求消息,以获得与业务标识和第一组标识均对应的配置。
S513、若第二用户设备已获得与第一组标识和业务标识均对应的配置,则第二用户设备接收基站发送的与第一组标识和业务标识均对应的组通信数据。
采用本发明实施例提供的组通信方法,用户设备不需要存储与业务标识对应的组标识。在网络中应用服务器部署很密集的应用场景中,本发明实施例提供的组通信方法可以降低用户设备存储组标识的数量和复杂性,还提高了用户设备根据业务类型识别广播业务的能力。
示例性的,对于车联网业务,在车辆网中部署有大量V2I应用服务器(比如电子交通灯或电子限速牌)的应用场景中,若采用本发明实施例提供的组通信方法,每个V2I应用服务器只需要和广播服务器建立V2I业务的广播会话,且在空口广播的V2I业务对应的组标识中携带用于表示V2I业务类型的业务标识,则任一车辆根据该业务标识即可获知该广播会话的业务类型,从而确定自身是否需要接收该业务类型的业务。
若V2P应用服务器和广播服务器建立V2P业务的广播会话,且在空口广播的V2P业务对应的组标识中携带用于表示V2P业务类型的业务标识,则对于手持终端而言,手持终端只需要确定自身是否需要接收V2P信息,就可以确定是否需要后续获取该广播会话的配置,并接收该广播会话,而不需要关心其他车联网的广播会话,这样,可以降低手持终端设备的接收能耗。
需要说明的是,本发明上述实施例中,组通信网络系统中的各个节点在发送第一组标识时,还可以发送第一组标识的有效期。这样,在时间超过有效期后,服务器不再利用第一组标识发送组通信数据,保证了广播组通信数据的有效性。
