图1为本申请实施例提供的应用场景的示意图,如图1所示,本实施例提供了一种通信系统,该通信系统包括网络设备110和终端120,网络设备110包括核心网设备111和多个接入网设备112。在通信系统中,接入网设备112和终端120都有自己独立的时钟模块,时钟模块中晶体振荡器的时间误差、无线信号传播过程中的传播时延等,导致不同的接入网设备112之间、不同的终端120之间、以及接入网设备112与终端120之间都存在时间同步误差。
其中,该应用场景中的核心网设备111与接入网设备112可以是独立的不同的物理设备,也可以是将核心网设备111的功能与接入网设备112的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备111的功能和部分接入网设备112的功能。终端120可以是固定位置的,也可以是可移动的。图1只是示意图,该通信系统中还可以包括其它网络设备,如还可以包括无线中继器设备和无线回传设备,在图1中未画出。
随着通信技术的发展,通信系统在支撑传统业务(例如通话业务)之外,还将支撑更多的具有较高的时间同步需求的业务,例如定位业务、无人驾驶业务、虚拟现实业务,通信系统的时间同步需求变得更加多样化。
以3GPP引入5G系统接入TSN网络的网络部署机制为例,图2为本申请实施例 提供的又一应用场景的示意图。该应用场景为5G系统接入TSN的场景,在该应用场景中,TSN网络和5G系统都具有较高的时间同步需求。如图2所示,TSN系统与TSN的交换节点(Bridge)或者数据终端(End Station)通过5G系统建立通信连接,第一节点为,5G系统用作TSN的逻辑交换节点(Logical Bridge)。其中,5G系统通过桥接的方式分别与TSN系统、第一节点进行通信连接。
因此,在不同的应用场景中,通信系统的时间同步需求不同,3GPP系统评估的时间同步误差容许范围也相差较大。例如,运动控制(Motion control)、终端间时间同步(Control to Control,C2C)、高视频数据流(High data rata vidio streaming)、智能电网(Smart grid)等应用场景中,高视频数据流的时间同步需求为时间同步误差小于10微秒,终端间时间同步的时间同步需求为时间同步误差小于1微妙,终端间时间同步的时间同步误差允许范围为±145纳秒~±275纳秒,智能电网的时间同步误差允许范围为±795纳秒~±845纳秒。
目前,采用同一传播时延补偿(PDC,Propagation Delay Compensation)方式进行时间同步,而未考虑到不同的场景的时间同步需求不同,存在以下不足:一方面,对一些无需进行时间同步的场景(例如,基站与终端距离较近、且时间同步误差要求不高的场景)进行时间同步,造成系统开销较大;另一方面,若为节省系统开销采用时间同步精度不高的传播实验补偿方式进行时间同步,则无法满足一些时间同步需求较高的场景。
为解决上述问题,本申请实施例提供了一种信息处理方法、装置、设备及介质。在本申请中,根据时间同步场景信息,有针对性地确定目标时间同步策略,提高了时间同步策略的灵活性和针对性,能够有效地降低时间同步的系统开销,并能够满足不同场景的时间同步需求。
其中,本申请实施例所提供的方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
图3为本申请的一实施例提供的信息处理方法的流程示意图。本实施例中,信息处理方法的执行主体为接入网设备。如图3所示,该方法包括:
S301、获取时间同步场景信息。
其中,时间同步场景信息用于指示与特定时间同步需求对应的场景,与特定时间同步需求对应的场景是指场景有自身的时间同步需求,换句话说,时间同步场景信息用于指示当前进行时间同步的场景,不同场景的时间同步需求相同或不同。为便于描述,后续将与特定时间同步需求对应的场景称为时间同步场景。时间同步场景信息中,可以包括时间同步场景(可以理解为应用场景或者业务场景)、和/或时间同步场景的时间同步需求。
本步骤中,接入网设备可获取预先存储的时间同步场景信息,例如,根据接入网设备所在的时间同步场景,在接入网设备中预先设置时间同步场景信息;或者,接入网设备动态获取时间同步场景信息,例如,根据接收到的业务信息、或者与终端之间的通信距离等,确定时间同步场景信息。
S302、根据时间同步场景信息,确定目标时间同步策略。
其中,目标时间同步策略是指进行时间同步的方式。
本步骤中,接入网设备获得时间同步场景信息后,可根据时间同步场景信息,确定时间同步场景是否具有较高的时间同步需求。根据时间同步场景是否具有较高的时间同步需求,确定是否进行时间同步,以及确定用于时间同步的目标时间同步策略。
具体的,如果时间同步场景的时间同步需求较低,则可确定不进行时间同步,或者将时间同步精度不高但系统开销较小的时间同步策略确定为目标时间同步策略,以减小系统开销。如果时间同步场景的时间同步需求较高,则可将系统开销较大但时间同步精度较高的时间同步策略确定为目标时间同步策略,以提高时间同步效果。
本申请实施例中,接入网设备根据时间同步场景信息,有针对性地确定目标时间同步策略,提高时间同步策略的灵活性、合理性、以及在时间同步场景下的适用性,有利于降低系统开销并提高时间同步效果。
在一些实施例中,目标时间同步策略包括如下至少一项:传播时延补偿的方式、传播时延补偿的执行主体、进行传播时延补偿的补偿周期。因此,能够针对时间同步场景,确定传播时延补偿的方式、传播时延补偿的执行主体、进行传播时延补偿的补偿周期中的至少一项,有利于从一个或多个方面提高目标时间同步策略的合理性。
其中,传播时延为无线信号从发送端(例如接入网设备)传播至接收端(例如终端)的时间,传播时延是导致接入网设备与终端之间的时间同步误差的因素之一。传播时延补偿的方式是指对无线信号从发送端传播至接收端的时间进行补偿的方式。传播时延补偿的执行主体用于指示执行传播时延补偿的方式的主体,例如,若在接入网设备一侧进行传播时延补偿,则执行主体为接入网设备,若在终端一侧进行传播时延补偿,则执行主体为终端。进行传播时延补偿的补偿周期用于指示每隔一个补偿周期进行一些传播时延补偿,也即每隔一个补偿周期进行一次时间同步。
具体的,传播时延补偿的方式、传播时延补偿的执行主体、进行传播时延补偿的补偿周期,都是时间同步精度和时间同步的系统开销的影响因素。不同的传播时延补偿的方式的时间同步精度不同、系统开销不同,在不同的设备上进行传播时延补偿的时间同步精度不同、系统开销不同,进行传播时延补偿的补偿周期不同,时间同步精度也不同、系统开销也不同。
因此,接入网设备根据时间同步场景信息,确定目标时间同步策略时,可根据时间同步场景是否具有较高的时间同步需求,确定相应的时延补偿策略、传播时延补偿的执行主体、进行传播时延补偿的补偿周期中的至少一项。由时延补偿策略、传播时延补偿的执行主体、进行传播时延补偿的补偿周期中的至少一项,得到目标时间同步策略。
在一些实施例中,时间同步场景信息包括时间同步场景的目标场景标识、同步误差允许范围、业务对应的目标时间同步需求中的至少一项。根据时间同步场景信息,确定目标时间同步策略的一种可能的实现方式,包括:根据目标场景标识、目标同步误差允许范围、业务对应的目标时间同步需求中的至少一项,确定目标时间同步策略。其中,目标场景标识、目标同步误差允许范围、业务对应的目标时间同步需求这三项,与时间同步场景相关联的、且能够反映时间同步场景的时间同步需求,有利用进一步提高目标时间同步策略在时间同步场景下的适用性、准确性。
一示例中,时间同步场景信息包括时间同步场景的目标场景标识时,可预先配置 多个场景的场景标识,每个场景的场景标识唯一,预先配置场景的时间同步需求与场景标识的映射关系。在根据时间同步场景信息,确定目标时间同步策略时,从时间同步需求与场景标识的映射关系中,获取目标场景标识对应的时间同步需求,即得到时间同步场景的时间同步需求。进而,可根据时间同步场景的时间同步需求,确定目标时间同步策略。
另一示例中,时间同步场景信息包括目标同步误差允许范围和/或业务对应的目标时间同步需求时,可以根据目标同步误差允许范围和/或业务对应的目标时间同步需求,确定时间同步场景的时间同步需求,进而,可根据时间同步场景的时间同步需求,确定目标时间同步策略。
基于目标时间同步策略包括传播时延补偿的方式,图4为本申请的另一实施例提供的信息处理方法的流程示意图。本实施例中信息处理方法的执行主体为接入网设备。如图4所示,该方法包括:
S401、获取时间同步场景信息。
其中,S401的实现原理和技术效果可参照前述实施例,不再赘述。
S402、根据时间同步场景信息,确定目标同步误差允许范围。
其中,目标同步误差允许范围反映出时间同步场景的时间同步需求,换句话说,目标同步误差允许范围是指在时间同步场景中进行时间同步所要满足的时间误差范围。
本步骤中,接入网设备在获得时间同步场景信息后,确定时间同步场景信息对应的目标同步误差允许范围。
一示例中,时间同步场景信息包括时间同步场景的目标场景标识时,接入网设备可在场景标识与同步误差允许范围的映射关系中,查找与目标场景标识对应的同步误差允许范围,确定目标同步误差允许范围为与目标场景标识对应的同步误差允许范围。
其中,在接入网设备中,可预先配置多个时间同步场景的场景标识,且各时间同步场景的场景标识唯一,场景标识例如为场景编号、场景名称等。例如,终端间时间同步这一场景的场景标识为1,智能电网这一场景的场景标识为2。在接入网设备中,还可根据时间同步场景的时间同步需求,配置场景标识与同步误差允许范围的映射关系。例如,终端间时间同步这一场景的时间同步需求为同步误差小于1微秒,则在映射关系中,场景标识1对应的同步误差允许范围为小于等于1微秒。
具体的,在获得时间同步场景信息后,可从时间同步信息中获取目标场景标识。在场景标识与同步误差允许范围的映射关系中,查找与目标场景标识对应的同步误差运行范围。将查找到的与目标场景标识对应的同步误差允许范围,确定为目标同步误差允许范围。
另一示例中,时间同步场景信息包括目标同步误差允许范围时,接入网设备可直接从时间同步场景信息中获得目标同步误差允许范围。
又一示例中,时间同步场景信息包括业务对应的目标时间同步需求时,接入网设备可基于业务对应的目标时间同步需求,获取业务对应的目标同步误差允许范围。
其中,业务对应的目标时间同步需求例如为业务对时延可靠性的需求,业务对时延可靠性的需求可以体现为时延可靠性的允许误差范围,因此,可将该时延可靠性的允许误差范围,确定为业务对应的目标同步误差允许范围。业务例如定位业务、无人 驾驶业务、导航业务等。
S403、根据目标同步误差允许范围,确定目标时间同步策略中的传播时延补偿的方式。
本步骤中,接入网设备可根据目标同步误差允许范围,确定时间同步场景是否具有较高的时间同步需求。根据时间同步场景是否具有较高的时间同步需求,确定相应的传播时延补偿的方式。
具体的,将目标同步误差允许范围中的数值与一个或多个阈值进行比较,根据比较结果,确定相应的传播时延补偿的方式。例如,在目标同步误差允许范围中的数值小于或等于某一阈值(例如目标同步误差允许范围中的最大值、最小值或者中间值小于或等于某一阈值)时,表明时间同步场景的时间同步需求较高,此时可将时间同步精度较高的传播时延补偿的方式确定为目标时间同步策略中的传播时延补偿的方式。在目标同步误差允许范围中的数值大于某一阈值(例如目标同步误差允许范围中的最大值、最小值或者中间值大于某一阈值)时,表明时间同步场景的时间同步需求不高,此时可将时间同步精度不高的传播时延策略确定为目标时间同步策略中的传播时延补偿的方式。
本申请实施例中,接入网设备根据时间同步场景信息,确定反映时间同步场景的时间同步需求的目标同步误差允许范围,根据目标同步误差允许范围,确定目标时间同步策略中的传播时延补偿的方式。因此,提高时间同步策略中的传播时延补偿的方式的灵活性、合理性、以及在时间同步场景下的适用性,有利于降低系统开销并提高时间同步效果。
在一些实施例中,传播时延补偿的方式包括基于往返时延(Round Trip Time,RTT)的补偿策略、基于时间校准(Time Alignment,TA)的步长策略。此时,S403的一种可能的实现方式包括:若目标同步误差允许范围中的数值小于或等于第一阈值,则确定目标时间同步策略中的传播时延补偿的方式为基于RTT的补偿,否则,确定目标时间同步策略中的传播时延补偿的方式为基于TA的补偿。
其中,第一阈值为预设常数值。
可选的,目标同步误差允许范围中的数值小于或等于第一阈值,是指目标同步误差允许范围中的最大值小于或等于第一阈值,或者,是指目标同步允许范围中的最小值小于或等于第一阈值,或者,是指目标同步允许范围中的中间值小于或等于第一阈值。
其中,相较于基于TA的补偿,基于RTT的补偿的时间同步精度较高、系统开销较大。
具体的,接入网设备将目标同步误差允许范围中的数值与第一阈值进行比较。若目标同步误差允许范围中的数值小于或等于第一阈值,则说明时间同步场景的时间同步需求较高,确定目标时间同步策略中的传播时延补偿的方式为时间同步精度较高的基于RTT的补偿,以确保时间同步精度。若目标同步误差允许范围中的数值大于第一阈值,则说明时间同步场景的时间同步需求不高,确定目标时间同步策略中的传播时延补偿的方式为时间同步精度不高但开销较小的基于TA的补偿,以降低系统开销。因此,依据目标同步误差允许范围,有针对性地在基于RTT的补偿、基于TA的补偿 中确定目标时间同步策略中的传播时延补偿的方式,解决了在不同场景下采用相同的时延补偿策略所带来的系统开销较大、时间同步效果不佳的问题。
在一些实施例中,基于目标时间同步策略包括传播时延补偿的执行主体,根据时间同步场景信息,确定目标时间同步策略的一种可能的实现方式为:若时间同步场景信息对应的场景为终端间时间同步,则确定目标时间同步策略的执行主体为接入网设备。
其中,终端间时间同步这一场景包括不同终端之间的无线通信,在该场景中,无线通信的传输需要多次经过网络设备。例如,第一终端位于第一小区,第二终端位于第二小区,第一终端与第二终端进行通信时,第一终端将无线信号发送至第一小区所属的网络设备,第一小区所属的网络设备再将接收到的无线信号转发给第二小区所属的网络设备,第二小区所属的网络设备将该无线信号发送给第二终端。因此,终端间时间同步这一场景对时间同步的效率要求较高。
具体的,相较于终端一侧的时间同步,接入网设备一侧的时间同步的效率更高。因此,接入网设备在确定时间同步场景信息对应的场景为终端间时间同步时,例如,时间同步场景信息中的目标场景标识为终端间时间同步的场景标识时,确定目标时间同步策略的执行主体为接入网设备。
可选的,接入网设备若确定时间同步场景信息对应的场景为终端与基站间时间同步,例如智能电网这一场景,考虑到终端与基站间的时间同步仅进过一次网络设备,对时间同步的效率要求不高,因此,确定目标时间同步策略的执行主体为终端,以减小接入网设备的系统开销。
其中,确定目标时间同步策略的执行主体的方式可与确定目标时间同步策略中的传播时延补偿的方式相结合。在确定目标时间同步策略的执行主体的同时,确定目标时间同步策略中的传播时延补偿的方式。
例如,在时间同步场景信息对应的场景为终端间时间同步、且目标同步误差允许范围中的数值小于或等于第一阈值时,接入网设备确定目标时间同步策略的执行主体为接入网设备,并确定目标时间同步策略中的传播时延补偿的方式为基于RTT的补偿。又如,在时间同步场景信息对应的场景不为终端间时间同步、且目标同步误差允许范围中的数值大于第一阈值时,接入网设备确定目标时间同步策略的执行主体为终端,并确定目标时间同步策略中的传播时延补偿的方式为基于TA的补偿。
在一些实施例中,基于目标时间同步策略包括补偿周期,根据时间同步场景信息,确定目标时间同步策略的又一种可能的实现方式为:根据时间同步场景信息,确定基于目标时间同步策略进行时间同步的补偿周期。
具体的,若接入网设备根据时间同步场景信息,确定时间同步场景的时间同步需求较高,则可以确定一个较短的补偿周期,以提高时间同步精度。若根据时间同步场景的信息,确定时间同步场景的时间同步需求不高,则可以确定一个较长的补偿周期,以合理降低时间同步带来的系统开销。
进一步地,预先设置第一时长和第二时长,第一时长小于第二时长。在根据时间同步场景信息,确定目标同步误差允许范围后,接入网设备可确定目标同步误差运行范围是否小于或等于第二阈值。若是,则确定补偿周期为第一时长,否则,确定补偿 周期为第二时长。其中,目标同步误差运行范围满足第二条件,表示时间同步场景的时间同步需求较高。
其中,第二阈值为预设常数值。第二阈值可与前述的第一阈值为不同的值,也可为相同的值。
可选的,目标同步误差允许范围中的数值小于或等于第二阈值,是指目标同步误差允许范围中的最大值小于或等于第二阈值,或者,是指目标同步允许范围中的最小值小于或等于第二阈值,或者,是指目标同步允许范围中的中间值小于或等于第二阈值。
具体的,将目标同步误差允许范围中的数值与第二阈值进行比较。若目标同步误差允许范围中的数值小于或等于第二阈值,则说明时间同步场景的时间同步需求较高,为提高时间同步精度,确定补偿周期为第一时长。若目标同步误差允许范围中的数值大于第二阈值,则说明时间同步场景的时间同步需求不高,为降低时间同步带来的系统开销,确定补偿周期为第二时长。
进一步地,除了第一时长、第二时长两个时长,还可以预先设置第三时长、第四时长等,除了第二阈值,还可预先设置第三阈值、第四阈值等。根据多个阈值,对时间同步场景的时间同步需求进行更细致的划分,并根据划分结果,在多个时长中确定补偿周期。
可选的,确定目标时间同步策略的执行主体的方式、确定目标时间同步策略中的传播时延补偿的方式、确定目标同步策略中补偿周期的方式可以相互组合。例如,接入网设备在确定目标时间同步策略的执行主体的同时,确定目标时间同步策略中的传播时延补偿的方式和/或确定目标时间同步策略中的步长周期。例如,接入网设备在确定时间同步场景信息对应的场景为终端间时间同步、目标同步误差允许范围中的数值小于或等于第一阈值、且目标同步误差允许范围中的数值小于或等于第二阈值时,确定目标时间同步策略的执行主体为接入网设备,确定目标时间同步策略中的传播时延补偿的方式为基于RTT的补偿,并确定目标时间同步策略中的补偿周期为第一时长。
在一些实施例中,接入网设备获取的时间同步场景信息可来自终端或者核心网设备,因此,接入网设备可动态获取时间同步场景信息,有利于提高时间同步场景信息的准确性。
图5为本申请的另一实施例提供的信息处理方法的流程示意图。如图5所示,本实施例的方法可以包括:

可选的,终端向接入网设备发送第一消息之前,终端可接收核心网设备发送的时间同步场景信息。

具体的,上行时间同步需求的业务是指:在该业务中,要求不同距离的不同终端的上行信号能够同步到达接入网设备。因此,终端有上行时间同步需求的业务时,需要进行时间同步,向接入网设备发送第一消息。
具体的,终端发生切换接入新小区时,终端和新小区所属的接入网设备之间可能存在较大的时间同步误差,为确保终端与新小区的正常通信,终端可向新小区所属的接入网设备发送第一消息。
