Description

一种发送消息的方法及相关设备
本申请要求于2018年5月10日提交中国国家知识产权局、申请号为201810447656.6、发明名称为“一种发送消息的方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种发送消息的方法及相关设备。
背景技术
当前，车联网技术已经成为汽车新技术发展的热点，国内外标准组织均积极参与车联网技术的建设，大力发展车联网，有利于促进汽车产业创新发展，构建汽车和交通服务新模式新业态，促进自动驾驶技术创新和应用。第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义的车联网(Vehicle to Everything，V2X)技术包括4大类：车车通信(Vehicle to Vehicle，V2V)、车与基础设施通信(Vehicle to Infrastructure，V2I)、车与行人通信(Vehicle to Pedestrian，V2P)和车与网络通信(Vehicle to Network，V2N)。
在现有的V2X技术中，所有V2X设备都是以一定频率向周围广播V2X消息。例如，假定为双向8车道道路，4方向1000米范围；拥堵情况下每条车道每10米1辆车(含车长)；数据上传频率为100毫秒，数据包大小为1KB；时长统计为12小时；则V2X设备广播的数据量(GB/每天)为：1000米/10米/车×4车道×8方向×10条/秒＝3.2万条/秒×1KB＝32MB/s×3600秒×12小时＝1382.4GB/天。
当前技术中的V2X业务消息交互频繁，V2X数据体量大，对平台及网络造成负荷。
发明内容
本申请实施例提供了一种发送消息的方法及相关设备，用于实现动态的调整发送频率来发送消息；发送消息的方法应用于车联网的通信系统，该通信系统包括终端和服务器，该终端包括发送消息的装置，该终端用于周期性广播消息，该消息为终端自身状态的消息，该状态包括终端的位置、速度、朝向、设备状况等；该终端也可以接收周边终端广播的消息。
第一方面，本申请实施例提供了一种发送消息的方法，该方法可以应用于一种发送消息的装置，该装置接收来自服务器的第一频率配置信息，第一频率配置信息用于指示终端发送消息的频率，第一频率配置信息包括至少一个配置参数，配置参数的参数值集合，及所参数值集合中的每个参数值所对应的第一发送频率；该装置确定当前时刻配置参数对应的第一参数值；然后装置将第一参数值与参数值集合进行匹配，进而确定在参数值集合中与第一参数值相匹配的第二参数值；每个第二参数值具有对应的第一发送频率，装置可以按照第二参数值对应的第一发送频率发送消息。本申请实施例中，终端在不同时刻确定的第一参数值不同，则与该第一参数值相匹配的第二参数值也可能不同，每个第二参数值具有对应的第一发送频率，按照第一参数值对应的第一发送频率发送消息(如自身的状态信息)，终端可以根据第二参数值所对应的第一发送频率对当前发送消息的频率进行动态调整，不需要按照固定频率发 送的消息，可以按照较低的发送频率来发送消息，以减少发送消息的数据量，并降低网络和终端的负荷。
在一种可能的实现方式中，至少一个配置参数包括速度，参数值集合包括速度值集合，装置检测当前时刻的第一速度值；然后，终端将第一速度值与速度值集合进行匹配，确定在速度值集合中与第一速度值相匹配的第二速度值，第一发送频率为在第一配置信息中与第二速度值对应的发送频率。本申请实施例中，至少一个配置参数包括速度，该速度值集合中包括多个第二速度值，多个第二速度值中的每个第二速度值都会对应一个发送频率，终端可以根据当前时刻的第一速度值的变化来调整发送消息的发送频率，例如，当车辆以较慢的速度行驶的时候，可以以较低的发送频率发送消息，当车辆以较快的速度行驶的时候，可以以较高的发送频率发送消息，以实现根据第一频率配置信息动态调整发送消息的发送频率，减少发送消息的数据量。
在一种可能的实现方式中，至少一个配置参数包括地理位置，在第一频率配置信息中，每个地理位置的参数值对应N个速度值，N个速度值中的每个速度值对应有第一发送频率，N为大于或者等于1的正整数。本申请实施例中，每个地理位置的参数值对应N个速度值，例如，地理位置可以包括市区、高速、高架桥等，在不同的地理位置对应的发送频率不同，装置可以根据当前的地理位置及当前地理位置所对应的速度值来动态的调整发送消息的发送频率。
在一种可能的实现方式中，将第一参数值与参数值集合进行匹配，确定在参数值集合中与第一参数值相匹配的第二参数值具体的方式具体的可以为：装置获取当前时刻的第一位置及第一速度值；首先将当前时刻的第一位置与地理位置的参数值进行匹配，确定在频率配置信息中的第二位置；然后将当前时刻的第一速度值与第二位置对应的N个速度值进行匹配，确定在N个速度值中与第一速度值相匹配的第二速度值；然后，装置按照第二速度值对应的第一发送频率发送消息。本申请实施例中，装置可以根据当前的地理位置及当前地理位置所对应的速度值来动态的调整发送消息的发送频率。

步骤301、终端向CF发起启动连接(on boot connection)，CF向终端反馈响应，终端与CF进行连接。
步骤302、CF授权终端使用车联网的相关业务，并向终端发送通信参数(包括但不限定于无线资源、授权的业务，或V2X应用服务器的IP地址等)；
步骤303、终端通过基站根据应用服务器的IP地址与应用服务器连接，并向应用服务器上报终端的ID和该终端的设备类型。
该设备类型包括但不限定于路测单元(Road Side Unit，RSU)，车辆设备(Vehicle User Equipment，V-UE)和行人设备(Pedestrian User Equipment，P-UE)。
需要说明的是，步骤301-步骤303为可选步骤，若终端与应用服务器已经建立连接，则不需要执行上述步骤301-步骤303，而直接执行步骤304。
步骤304、应用服务器配置第一频率配置信息，第一频率配置信息包括至少一个配置参数，至少一个配置参数的参数值集合，及第一参数值集合中每个第一参数值对应的第一发送频率。
至少一个配置参数中的每个配置参数均对应一个参数值集合，例如，第一配置参数对应第一参数值集合，第二配置参数对应第二参数值集合等等。
应用服务器配置第一频率配置信息，例如，该至少一个配置参数包括但不限定于速度、业务、地理位置中的至少一个，且每个配置参数具有对应的参数值集合，参数值集合中的每个参数值具有对应的第一发送频率。
例如，业务包括但不限定于常规业务、红绿灯业务，告警业务和故障业务等。
地理位置包括但不限定于高速、城市、郊区、十字路口等。
在第一个可能实现的方式中，配置参数还可以包括设备类型，如设备类型对应的参数值集合包括路测单元和车辆设备(商用车车载设备，卡车车载设备等)等，每个参数值对应一个第一发送频率，例如，路测单元对应的第一发送频率为30Hz，且当设备类型为路测单元时，发送消息的发送频率为固定值；当设备类型为车辆设备和行人设备时，发送消息的发送频率可以为多个，根据配置参数的不同参数值对应不同的发送频率，车载设备对应的第一发送频率为10Hz。或者，不同的车载设备对应不同的发送频率，例如，商用车车载设备对应的第一发送频率为10Hz，卡车车载设备对应的发送第一发送频率为5Hz。
需要说明的是，本申请实施例中，设备类型和第一发送频率对应的具体数据均为举例说明，并不造成对本申请的限定性说明。
在第二个可能实现的方式中，应用服务器可以根据终端上报的设备类型为该终端配置与该设备类型相对应的第一频率配置信息。频率配置信息可以以配置信息表的形式进行举例，下面该频率配置信息以以下3个示例进行举例。
1、第一频率配置信息中包括1个配置参数，当终端为车量设备时，配置参数为速度时，该第一频率配置信息如下表1所示：
表1
Figure PCTCN2019085652-appb-000001
2、第一频率配置信息中包括2个配置参数，配置参数包括地理位置和速度，该第一频率配置信息如下表2所示：
表2

3、第一频率配置信息中包括3个配置参数，配置参数包括地理位置，速度和业务，该第一配置信息如下表3所示：
表3
Figure PCTCN2019085652-appb-000003
在表3中，业务对应的参数值集合为业务ID值集合，业务ID值集合中不同的业务ID值对应不同的业务。例如，“700”表示常规业务，“710”表示“红绿灯业务”，“720”表示“告警业务”，“730”表示“故障业务”等等，表3中的业务及ID值均是举例说明，并不造成对本申请的限定性说明。
需要说明的是，上述表1、表2及表3中的配置参数及每个配置参数对应的参数值集合均为举例说明，并不造成对本申请的限定性说明。
应理解，本申请实施例中的第一频率配置信息中包括至少一个配置参数，对于表1、表2和表3中的频率配置参数只是举例说明，并不造成对本申请的限定性说明，且第一频率配置信息中的配置参数可以为上述多个配置参数中至少一个。例如，在另一个示例中，该第一频率配置信息中也可以只包括业务这个配置参数，或者，也可以只包括地理位置这个配置参数，或者，也可以包括业务和地理位置等等。
步骤305、终端接收来自服务器发送的第一频率配置信息，并确定当前时刻配置参数对 应的第一参数值。
在第一个示例中，终端接收来自应用服务器发送的第一频率配置信息，该第一频率配置信息如表1所示，终端按照第一频率配置信息中的配置参数(速度)检测当前时刻的速度值为70。
在第二个示例中，该第一频率配置信息如表2所示，终端按照第一频率配置信息中的配置参数(地理位置和速度)，确定当前的地理位置(如市区)，检测当前时刻的速度值(如70)。
在第三个示例中，该第一频率配置信息如表3所示，当配置参数包括地理位置、速度和业务时，终端确定当前时刻的业务(如常规业务)，确定当前的地理位置(如市区)，检测当前时刻的速度值(如80)。
步骤306、终端将第一参数值与参数值集合进行匹配，确定在参数值集合中与第一参数值相匹配的第二参数值。
在第一个示例中，当该第一频率配置信息如表1所示时，终端将当前检测到的第一速度值(如70)与表1中的速度值集合进行匹配，确定在度值集合中与第一速度值相匹配的第二速度值，如，当前检测的速度为70，当前检测的速度与表1中的速度值集合相匹配的第二速度值(如50-80)。
在第二个示例中，当该第一频率配置信息如表2所示时，配置参数包括地理位置，在第一频率配置信息中，每个地理位置的参数值对应N个速度值，N个速度值中的每个速度值对应有第一发送频率，N为大于或者等于1的正整数。在表2中，包括2个地理位置，如市区和高速。
应理解，在表2中只是对地理位置及每个地理位置对应的速度值集合进行举例说明，并不作为限定性说明，当然，地理位置还可以包括十字路口、高架桥等，此处不一一举例。
终端检测到当前位置(如市区)及当前时刻的第一速度值(如70)。
首先，终端将当前时刻的第一位置(市区)与地理位置的参数值(市区和高速)进行匹配，确定在第一频率配置信息中的第二位置，该第二位置为“市区”。
每个地理位置对应N个速度值，例如，如表2中，“市区”对应的5个速度值范围，该5个速度值分别为“0-20”、“20-50”、“50-80”、“80-120”、“120-以上”。
然后，终端将当前时刻的第一速度值70与第二位置对应的N个速度值进行匹配，确定在5个速度值中与第一速度值70相匹配的第二速度值“50-80”。
在第三个示例中，配置参数为业务，参数值集合包括业务ID值集合，终端确定当前所执行的第一业务；将第一业务的ID值与业务ID集合进行匹配，确定在业务ID集合中与第一业务相匹配的第二业务ID值。
在第四个示例中，第一频率配置信息还包括配置参数优先级，至少一个配置参数中每个配置参数具有对应的优先级，业务为优先级最高的配置参数。
当该第一频率配置信息如表2或3所示时，第一频率配置信息中包括至少两个配置参数时，每个配置参数具有对应的优先级，其中，业务具有最高的优先级(第一优先级)，速度具有第二优先级等。
终端根据配置参数的优先级确定至少一个配置参数中的目标配置参数；例如，2个配置参数分别为速度和业务时，终端确定优先级别高的配置参数为目标配置参数，根据目标配置 参数的参数值集合中的第二参数值对应的第一发送频率调整当前发送消息的频率。例如，当2个配置参数分别为速度和业务时，业务的优先级别最高，终端确定当前时刻的第一业务，终端首先将第一业务与第一频率配置信息中的业务ID值集合进行匹配，例如，当前时刻的第一业务为“红绿灯业务”，红绿灯业务的ID值为“710”，将当前的第一业务与业务ID值集合进行匹配，确定相匹配的目标业务ID值为“710”。
步骤307、终端按照第二参数值对应的第一发送频率发送消息。
在第一个示例中，参阅表1，第二参数值(速度值)为“50-80”、终端根据第一频率配置信息中参数值与消息发送频率的对应关系，速度值为“50-80”时，对应的消息发送频率中的第一发送频率为“10”。
在第二示例中，参阅表2，“市区”中，当速度值为“50-80”时，对应的消息发送频率中的第一发送频率为“10”。
在第三个示例中，参阅表3所示，当第一业务ID值为“710”时，与该目标业务ID值“710”对应的第一发送频率为“10”。
本申请实施例中，终端接收来自服务器的第一频率配置信息，该第一频率配置信息包括至少一个配置参数，终端接收到第一频率配置信息后，可以根据第一频率配置信息中的配置参数确定当前时刻配置参数对应的第一参数值，然后将第一参数值与第一频率配置信息中的参数值集合进行匹配，确定在参数值集合中与第一参数值相匹配的第二参数值；随着时间的变化，当前的第一参数值不同，与该第一参数值相匹配的第二参数值可能不同，然后，终端可以根据第一频率配置信息中第二参数值所对应的第一发送频率发送消息，由于该第一频率配置信息中的每个参数值具有对应的第一发送频率，因此终端可以根据第二参数值所对应的第一发送频率对当前发送消息的频率进行动态调整，例如，不需要按照固定频率发送的消息，可以按照较低的发送频率来发送消息，以减少发送消息的数据量，并降低网络和终端的负荷。
在图2对应的实施例基础上，可选的，终端在接收到第一频率配置信息后，还可以接收来自应用服务器发送的更新之后的第二频率配置信息，该第二频率配置信息用于指示终端可以根据更新之后的第二发送频率发送消息。
在一种可能的实现方式中，终端按照第一发送频率(如10Hz)向服务器发送目标业务对应的目标消息，例如，该目标业务为一些需要特殊业务，如故障业务、碰撞业务等等。
应用服务器接收到终端发送的目标消息，目标消息用于指示服务器根据目标消息更新第一频率配置信息，得到更新后的第二频率配置信息，第二频率配置信息包括更新后的第二发送频率。
应用服务器接收到目标消息，确定终端当前的业务为故障业务，应用服务器可以根据该故障业务为终端配置频率配置信息，即更新后的第二频率配置信息，该第二频率配置信息包含至少一个配置参数，该第二频率配置信息可以参照表1、表2和表3进行理解。在一个应用场景中，当应用服务器接收到目标消息，确定终端当前的业务，表明该终端当前发生危险，需要提高终端发送消息的发送频率来保障终端的安全，故而应用服务器重新配置频率信息，重新配置的第二频率配置信息，该第二频率配置信息包括业务及该业务对应的第二发送频率，例如，该第二频率配置信息中包括故障业务(ID值为“730”)，该故障业务对应的第二发送 频率为40Hz(第一发送频率为20Hz)。该第二发送频率较第一发送频率增大，实现动态的调整发送频率，并提高不同业务的安全性。
需要说明的是，本申请实施例中，为了区分更新之后的频率配置信息和发送频率，在本申请中，“第一频率配置信息”为更新之前的频率配置信息，“第二频率配置信息”为更新之后的频率配置信息，第一频率配置信息中的第一发送频率为更新之前的发送频率，第二频率配置信息中的第二发送频率为更新之后的发送频率。
终端接收到第二频率配置信息后，按照第二频率配置信息的指示调整发送消息的发送频率。当终端接收到第二频率配置信息，将当前时刻的目标业务与第二频率配置信息中的业务进行匹配，确定第二频率配置信息中的“故障业务”对应的第二发送频率(如40Hz)，终端按照更新后的第二发送频率(如40Hz)发送消息。
本示例中，应用服务器为终端配置第一频率配置信息，根据实际业务的需要，应用服务器也可以对第一频率配置信息进行更新，更新该目标业务(如故障业务)所对应的第二发送频率(如40Hz)，终端接收到该第二频率配置信息，按照更新后的第二发送频率发送消息，终端按照第二频率配置信息的指示动态的调整发送消息的频率，即减少了系统中所有终端的广播消息的数据量，又可以提高车辆在某些特殊业务(如故障业务)时的安全性。
在另一种可能的实现方式中，应用服务器也可以根据全局信息和终端当前的业务为终端更新频率配置信息，该全局信息可以理解为在V2X通信系统中，应用服务器当前的空口资源的信息。例如，当前V2X通信系统中所有终端占用的无线资源的情况为所有终端中的各个终端进行统一配置发送消息的发送频率。
在一个应用场景中，若该V2X通信系统中包括连接态的终端A，终端B和终端C，若终端A当前发送消息的发送频率为10Hz，终端B当前发送消息的发送频率为10Hz，终端C当前发送消息的发送频率为10Hz，假设应用服务器当前已无可分配的无线资源，服务器可以根据当前的全局信息为各个终端配置更新后的第二频率配置信息。例如，若终端C当前为故障业务，终端C按照10Hz的发送频率通过基站向应用服务器发送故障业务的目标消息，该目标消息携带该故障业务的ID，应用服务器接收到目标消息后，根据该目标消息确定终端C当前的业务为故障业务，若应用服务器提高终端C的发送频率，则需要降低终端A和终端B的发送频率。应用服务器为终端A和终端B重新配置发送消息的发送频率，并向终端A发送频率配置信息A，频率配置信息A用于指示终端A调整当前的消息发送频率为5Hz，即将终端A的消息发送频率从10Hz降低至5Hz；应用服务器向终端B发送频率配置信息B，频率配置信息B用于指示终端B调整当前的消息发送频率为5Hz，即将终端B的消息发送频率从10Hz降低至5Hz；应用服务器为终端C配置第二频率配置信息，该第二频率配置信息包括配置参数(故障业务)和该故障业务对应的第二发送频率为20Hz，即将终端C的消息发送频率从10Hz提高到20Hz，终端根据更新后的第二频率配置信息调整消息发送频率为20Hz，本示例中，应用服务器根据V2X通信系统中的全局信息调整系统中终端的发送消息的发送频率，即节省了无线资源，又提高了某些业务的安全性。
为了理解本申请实施例，在一个应用场景中，终端D为车辆设备，车辆在高路上行驶，且该终端D与应用服务器连接，应用服务器通过基站向终端D发送第一频率配置信息，该第 一频率配置信息如上表2所示，即第一频率配置信息包括2个配置参数，即速度和位置，终端A检测当前的速度是“90”，获取当前的位置为“高速”，终端D将当前的位置与接收到的第一频率配置信息中的位置对应的参数值集合(市区和高速)进行匹配，确定地理位置对应的参数值为“高速”，将终端D自身对应的速度90与第一频率配置信息中的高速所对应的速度值进行匹配，如表2所示，与终端D自身的第一速度值90相匹配的第二速度值为(80-120)，第二速度值(80-120)对应的消息发送频率为20Hz，此时，终端按照频率20Hz发送消息，当车辆的行驶速度较快时，需要配置较高的发送频率，以保证可以高频率的通知周围终端自身的状态信息，提高车辆行驶的安全性。当车辆行驶到市区后，终端检测当前的速度为40，终端会根据表2中所示的信息进行匹配，如表2所示，当速度为40时，匹配到表2中的速度值集合，确定第二速度值为(20-50)，该第二速度值(20-50)对应的消息发送频率为5Hz，在市区时，车辆行驶的速度较慢，因此发送消息的频率可以减小，也同样可以保障车辆的通信及安全，此时，终端D按照5Hz向周围的终端及服务器广播消息。本申请实施例中，终端可以根据频率配置信息中的消息发送频率灵活调整当前发送消息的发送频率，即可以减少无用的V2X消息，又使得V2X消息传输更高效。

服务器接收到目标消息，确定终端当前的业务为故障业务，服务器可以根据该故障业务为终端从新配置频率配置信息，即更新后的第二频率配置信息，该第二频率配置信息包含至少一个配置参数，该第二频率配置信息可以参照表1、表2和表3进行理解。在一个应用场景中，当边缘服务器接收到目标消息，确定终端当前的业务为故障业务，表明该终端当前发生危险，需要提高终端发送消息的发送频率来保障终端的安全，故而边缘服务器重新配置频率信息，重新配置的第二频率配置信息，该第二频率配置信息包括业务及该业务对应的第二发送频率。
步骤510、边缘服务器将该更新后的第二频率配置信息向中心服务器发送。
