本申请涉及通信领域,尤其涉及一种数据处理的方法、装置和***。
在车联网(Vehicle-to-everything,V2X)通信场景中,可以包括多种应用场景,例如,车辆组队、传感器扩展、远程驾驶或驾驶增强等等。为了支持这些应用场景的实现,侧链路(Sidelink,SL)的基于邻近通信5(prose communication 5,PC5)接口的车到车(vehicle-to-vehicle,V2V)通信需要支持低时延高可靠的传输需求。且不同于Uu口通信,用户设备(user equipment,UE)与基站之间的上下行通信方式,SL通信采用用户直接连接的通信方式。
通常,在V2X通信场景下,UE可能处于运动状态,而SL通信的通信质量也时刻处于变化中。因此,UE并不能准确地确定出适应SL通信质量的网络资源。因此,如何使UE使用准确的网络资源进行通信,成为亟待解决的问题。

为便于理解,下面对本申请实施例涉及的一些术语进行介绍:
车联网(vehicle-to-everything,V2X):可以通过装载在车上的传感器或车载终端设备等提供车辆信息,实现车辆到车辆(vehicle to-vehicle,V2V),车辆到基础设施(vehicle-to-infrastructure,V2I),车辆到网络(vehicle-to-network,V2N)以及车辆到行人(vehicle-to-pedestrian,V2P)之间的通信。因此,车联网涉及的终端设备可以被称为V2X终端设备。
侧链路(side link,SL):V2X终端设备之间的直接通信的链路。V2X终端设备之间可以通过侧行链路接口进行短距离通信,该侧行链路接口还可以称为邻近通信5(prose communication 5,PC5)接口,或直通链路接口。

示例性地,本申请提供的数据处理的方法具体可以应用于V2X通信***,该通信***可以基于上述的各种通信网络。
该V2X通信***具体可以包括但不限于:统一数据管理(unified data management, UDM)网元、策略与控制功能(policy control function,PCF)实体、网络能力开放功能(network exposure function,NEF)实体、应用功能(application function,AF)实体、统一数据存储库(unified data repository,UDR)网元、接入管理功能(access and mobility management function,AMF)实体、会话管理功能(session management function,SMF)实体、用户面功能(user plane function,UPF)实体、无线接入网(radio access network,RAN)设备、网络数据分析功能(network data analysis function,NWDAF)实体(图中未示出)、数据分析实体等等。且各个网元或设备的数量可以是一个或多个。
AMF实体,主要负责终端设备的认证、终端设备的移动性管理、网络切片选择、会话管理功能实体的选择等功能。在本申请实施方式中,AMF实体可以对PCF实体发送或接收的数据进行转发,在本申请的以下实施例中,不再赘述。
PCF实体,主要负责提供策略规则给网络实体。包括提供统一的策略框架来控制网络行为,或者提供策略规则给控制层网络功能,同时负责获取与策略决策相关的用户签约信息。用于管理网络行为,为控制面提供策略、规则,一般根据签约信息等进行策略的决策。
RAN可以是由多个RAN设备组成的网络,实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能等。RAN设备通过用户面接口N3与UPF实体相连,用于传输终端设备的数据。RAN设备通过控制面接口N2和AMF实体建立控制面信令连接,用于实现无线接入承载控制等功能。其中,本申请图1中示出了无线接入网设备,即RAN设备,也可以替换为有线的接入网设备,图1中仅以RAN设备进行示例性说明,在本申请以下的说明中,直接称为接入网设备,即包括RAN设备以及有线接入网设备。具体的,接入网设备可以是具有中心控制功能的设备,如宏基站、微基站、热点(pico)、家庭基站(femeto)、传输点(transmission point,TP)、中继(relay)、接入点(access point,AP)等。若该接入网设备为基站,该基站可以是,长期演进(long term evolution,LTE)中的基站(eNodeB,eNB),新空口(new radio,NR)中的基站(gNodeB,gNB)等。
用户设备(user equipment,UE),用于向用户提供语音/数据连通性,例如,具有无线连接功能的手持式设备或车载设备等。也可以包括智能移动电话、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等等,以下也可以称为终端设备。
UPF实体,作为协议数据单元(protocol data unit,PDU)会话连接的锚定点,负责对用户设备的数据报文过滤、数据传输/转发、速率控制、生成计费信息等。
UDM网元,主要是管控用户数据。例如,签约信息的管理,可以包括:从UDR网元获取签约信息并提供给其它网元(例如AMF实体)、为终端设备生成3GPP的认证凭证和登记维护当前为终端设备服务的网元。
UDR网元,主要用于存储用户数据。用户数据可以包括由UDM网元调用的签约数据,PCF实体调用的策略信息,用于能力开放的结构化数据,NEF实体调用的应用数据。
NEF实体,用于连接核心网其它内部网元与核心网外部应用服务器,对外部应用服务器向核心网发起业务请求时提供认证与数据转发等服务,以将网络能力信息提供给外部应用服务器,或者将外部应用服务器的信息提供给核心网网元。在本申请实施方式中,在AF实体与核心网网元或者接入网设备等进行数据传输时,例如,PCF实体、接入网设备、数据 分析实体、NWDAF实体等,NEF实体可以对该数据进行转发。具体地,在AF实体向核心网网元或者接入网设备等发送数据时,NEF实体可以对该数据进行安全认证(由NEF对AF发送消息所携带的AF标识进行认证,确认该AF为运营商可信的AF)、标识转换(AF发送的消息可能携带外部标识,如所服务的用户标识或该消息的操作标识等,NEF需要将这些外部标识转换为核心网网元所识的内部标识)等步骤,使得核心网网元或者接入网设备可以安全并正确接收到AF实体发送的数据。通过运营商许可的AF可以通过NEF直接将消息发送给PCF实体或将消息通过NEF存储在UDR或UDM网元中,之后由PCF实体在UDR或UDM网元中读取或接收这些消息,核心网网元采用哪种方式获取AF消息由运营商在实际部署中决定。而AF需要将消息发送给接入网设备或经过核心网网元发送给UE时,则需要由PCF实体将这些消息经过AMF实体发送给接入网设备或由PCF实体经过AMF实体再经过接入网设备发送给UE。具体步骤在本申请以下的实施例中不再赘述。

此外,V2X通信***除了图1中所包括的网元之外,该网络架构还可以包括其他网元(图中未示出),例如,鉴权服务器功能(Authentication Server Function,AUSF)、网络切片选择功能(Network Slice Selection Function,NSSF)等,本申请实施例仅仅是示例性说明,具体可以根据实际应用场景进行调整。
示例性地,以接入网设备为基站为例,对具体的应用场景进行说明。例如,在V2X通信场景中,UE通过PC5接口进行SL通信,SL承载着重要的业务,例如,安全类业务,用于自动驾驶的传感器共享业务等。且不同于Uu口通信中,基站可以直接获取到其覆盖范围内的UE的网络资源的状况,例如,信道质量、拥塞情况等。在UE与UE之间的PC5接口通信中,基站无法直接获取到其覆盖范围内的UE的PC5接口的通信质量,例如,信道质量参数及拥塞情况信息等。根据当前UE上报的信道质量来估计网络的性能仅能判断出UE当前位置的网络情况。在UE上报了SL网络信息之后,随着UE的位置的移动,该UE所在位置的SL网络信息已改变,基站根据该UE上报的SL网络信息,并不能准确地为UE分配或调整其使用的网络资源。因此,本申请实施例提供了一种数据处理方法,可以更准确地对UE进行SL通信的网络资源进行调整。
下面基于上述图1的网络架构,对本申请提供的数据处理的方法进行说明。
请参阅图2,本申请实施例提供了一种数据处理方法,具体如下所述。
201、接入网设备获取预设范围内的N个栅格的信息。
其中,该预设范围可以是基于小区、扇区或基站设置的范围,也可以是基于地图设置的范围。例如,该预设范围为地图中的道路区域,或者,当该接入网设备为一个或多个基站时,该预设范围为该一个或多个基站下的一个或多个小区,或者,当该接入网设备为一个或多个基站时,该预设范围为一个或多个基站下的全部或部分扇区。其中,基站下的一个小区可以分为一个或多个扇区。
其中,该N个栅格可以是对该预设范围进行划分得到的栅格,N为大于或等于1的正整数。栅格的划分可以采用多种粒度。例如,以粒度为该预设范围内最小覆盖范围的小区的覆盖范围进行划分,使得上述每个栅格的覆盖范围小于该最小覆盖范围。再例如,以粒度为该预设范围内基站的最小扇区的覆盖范围进行划分,使得上述每个栅格的覆盖范围小于该最小扇区的覆盖范围。
其中,该N个栅格的信息可以包括:N个栅格中每个栅格的标识以及覆盖范围信息。其中,N个栅格中每个栅格的覆盖范围大小可以相同,也可以不相同。
其中,上述每个栅格的覆盖范围信息可以包括:上述每个栅格的长度以及宽度,或者,上述每个栅格的长度、宽度以及海拔。栅格的标识可以用于唯一标识一个栅格,例如,栅格的名字。需要指出的是,该N个栅格中的每个栅格的覆盖范围存在多种情况,例如,该每个栅格的覆盖范围的大小可以是预设值,即该每个栅格的覆盖范围的大小都相同。该每个栅格的覆盖范围大小也可以不相同,或者,还可以是该N个栅格中有部分栅格的覆盖范围大小相同。
通常,该每个栅格的覆盖范围可以划分为较小的范围。例如,该每个栅格的覆盖范围大小小于基站下的最小小区的覆盖范围大小,或者,该每个栅格的覆盖范围大小小于基站下的多个小区的平均覆盖范围大小,又或者,该每个栅格的覆盖范围大小小于基站下的最小扇区的覆盖范围大小等,以使后续在网络设备对网络资源进行分析时,可以基于比小区粒度更小,或者,比最小扇区粒度更小的栅格粒度进行分析,提高网络资源的分析结果的准确性。
其中,上述网络设备,以及本申请以下实施例中的网络设备,可以为图1中的NWDAF实体或者数据分析实体,本申请以下实施例中将不再赘述。
其中,步骤201可以采用多种方式实现,如下。
方式一,接入网设备可以接收来自其他网元的该N个栅格的信息。
其中,该其他网元可以是PCF实体,上述网络设备,或AF实体,不予限制。
例如,PCF实体对预设范围进行划分得到N个栅格,并将N个栅格的信息发送给接入网设备,进而接入网设备接收来自PCF实体的N个栅格的信息。
再例如,数据分析实体可以对预设范围进行划分得到N个栅格,并将N个栅格的信息发送给接入网设备,接入网设备接收来自数据分析实体的N个栅格的信息。
再例如,AF实体可以对预设范围进行划分得到N个栅格,并将N个栅格的信息发送给接入网设备,接入网设备接收来自AF实体的N个栅格的信息。
方式二,接入网设备对预设范围进行栅格划分,得到预设范围内的N个栅格的信息。
在一个示例中,接入网设备获取地图的信息,该预设范围可以是地图中的部分区域或全部区域。接入网设备可以基于该地图的信息,对该预设范围进行划分,得到预设范围内的N个栅格,并为N个栅格中的每个栅格分配标识,进而得到N个栅格的信息。
其中,该地图的信息可以包括该预设范围内的地理位置的信息,例如,该地图中可以包括该预设范围内的道路、山体、建筑等。该地图的信息可以是接入网设备上存储的,也可以是由其他网元发送至接入网设备,例如,可以由应用服务器(application server,AS)或UDR网元等将该地图的信息发送至接入网设备。
其中,接入网设备基于地图的信息,对预设范围进行划分,具体可以按照预设的大小进行划分,例如每个栅格的长度为20米,宽度为15米。
需要说明的是,若采用上述方式二,则上述方法还可以包括:接入网设备将该N个栅格的信息发送至其他网元,例如,PCF实体、NWDAF实体、AF实体或数据分析实体,不予限制。
202、接入网设备接收来自UE的第一SL网络信息。
其中,接入网设备可以接收来自一个或多个UE的第一SL网络信息。
具体地,该第一SL网络信息可以包括以下至少一项:UE的位置信息、信道质量信息、V2X业务信息或者道路信息等。
其中,该UE的位置信息可以包括UE所处位置的经度、纬度、海拔等。
其中,该信道质量信息可以包括表征UE当前进行SL通信的通信质量的信息,具体可以包括信道质量参考信息,或者,信道忙碌率(channel busy ratio,CBR)信息等。该信道质量参考信息可以包括:用于衡量基于PC5接口进行V2X业务的数据传输时对应的信道质量的信息,例如,误块率(block error rate,BLER)、信干噪比(signal to interference plus noise ratio,SINR)、接收功率等。
其中,该V2X业务信息可以包括UE当前执行的V2X业务的相关信息,例如,该V2X业务的业务类型、用于传输该V2X业务的数据的信道占用量、该V2X业务的数据包优先级、该V2X业务的通信参数、该V2X业务对应的接口信息等。具体地,该V2X业务的通信参数可以包括:V2X业务的PC5资源的等级或V2X业务的PC5服务质量标识(PC5QoS identifier,PQI)等;该V2X业务对应的接口信息可以包括:用于传输该V2X业务的数据的通信接口的类型或标识等。
其中,该道路信息可以包括UE当前所处道路的情况,例如,该道路信息包括UE在当前道路上所处位置周边一定范围内的交通流密度、车辆行驶速度等等。其中,该一定范围可以是在道路上,以该UE所处位置为中心,长度为UE所处位置前后100米的范围。该道路信息还可以包括该UE上的传感器或摄像头等采集到的路况信息,例如,道路图像、温度、湿度、可见度等。
在一种可选的实施方式中,该第一SL网络信息还包括时间信息,即第一SL网络信息的采集时间,使得接入网设备根据该第一SL网络信息的采集时间,确定该第一SL网络信息是否可用,或可用的权重。该时间信息以下也可以称为时间戳。例如,接入网设备可以 根据该时间戳获取到该第一SL网络信息的采集时间,从而根据采集时间确定该第一SL网络信息是否已过期。若该第一SL网络信息的采集时间与当前时间相差大于预设时间值,则可以丢弃该第一SL网络信息。
需要说明的是,UE可以周期性地上报第一SL网络信息,以使接入网设备可以实时获取到UE的SL网络信息。进而,接入网设备可以根据UE上报的第一SL网络信息,获取到UE进行SL通信的通信质量的信息,以便对UE进行网络资源调整或网络资源分配等。
203、接入网设备根据第一SL网络信息,向网络设备发送第一栅格的标识以及第一栅格相关的第二SL网络信息。
其中,第一栅格为UE所处的栅格,即UE位于第一栅格。N个栅格包括该第一栅格,换言之,该第一栅格为N个栅格中的一个或多个栅格。
其中,第一栅格相关的第二SL网络信息可以指的是与该一个或多个栅格相关的SL通信的信息。例如,该第二SL网络信息可以包括:处于第一栅格内的UE的标识、第一栅格覆盖范围内的信道质量信息、第一栅格覆盖范围内一个或多个UE的V2X业务信息或者第一栅格覆盖范围内的道路信息等。其中,信道质量信息,V2X业务信息,以及道路信息等均可以参考步骤202中的相关描述。
其中,第一SL网络信息与第二SL网络信息可以相同,也可以不同。
其中,当第一SL网络信息与第二SL网络信息相同时,步骤203可以包括:将该第一SL网络信息作为该第二SL网络信息,并向网络设备发送第一栅格的标识以及第二SL网络信息。
当第一SL网络信息与第二SL网络信息不相同时,步骤203可以包括:接入网设备根据第一SL网络信息,得到第二SL网络信息,并向网络设备发送第一栅格的标识以及该第二SL网络信息。
其中,上述接入网设备根据第一SL网络信息,得到第二SL网络信息可以采用两种方式。
方式一、接入网设备对第一SL网络信息进行预处理,得到第二SL网络信息。
示例性地,若接入网设备接收到一组第一SL网络信息,则可以在该一组第一SL网络信息中添加、删除或修改部分数据等,得到第二SL网络信息。若接入网设备接收到多组第一SL网络信息,接入网设备接收到多组第一SL网络信息,若其中包括不同频段(或信道)、不同道路或不同位置等信息,可以对该多组第一SL网络信息所包括的不同信息进行分类合并(例如,将同一位置不同频段第一SL网络信息进行归类合并或同一频段不同位置的第一SL网络信息进行归类合并等)。接入网设备还可以对该多第一SL网络信息中包括的参数进行计算,得到该第二SL网络信息。例如,可以对该多组第一SL网络信息中所包括的用于衡量相同信道的信道质量的参数,如误块率(block error rate,BLER)、信干噪比(signal to interference plus noise ratio,SINR)、接收功率等等,进行加权或平均运算,得到运算后的参数,进而得到第二SL网络信息,该第二SL网络信息即包括该运算后的参数。本申请实施例中,可以通过对第一SL网络信息进行预处理的方式,得到第二SL网络信息,减少接入网设备发送给网络设备的第二SL网络信息的冗余量,提高后续网络设备基于该第 二SL网络信息进行网络资源分析的效率。
方式二,接入网设备向数据分析实体发送第一SL网络信息,数据分析实体对第一SL网络信息进行预处理得到第二SL网络信息,并向接入网设备发送第二SL网络信息。
此外,在步骤203中,接入网设备可以根据UE所处的位置,以及N个栅格的信息,确定UE处于第一栅格。其中,UE所处的位置可以由UE上报,例如,通过第一SL网络信息上报,也可以由接入网设备对UE进行定位得到,或者,接入网设备从其他网元处获取到,不予限制。
在一种具体的实现方式中,第一栅格的覆盖范围小于UE当前接入小区的覆盖范围,即第一栅格的粒度小于小区的粒度。接入网设备向网络设备发送第一栅格的SL网络信息,例如,第二SL网络信息,用于网络设备得到基于第一栅格的网络资源分析结果。由于第一栅格比小区更小粒度,因此基于第一栅格的网络资源分析结果准确性更高,图2所示的方法能够大大提高网络资源分析结果的准确性。
在本申请实施例提供的方法中,接入网设备可以获取预设范围内的N个栅格的信息,并接收来自UE的第一SL网络信息。然后接入网设备根据第一SL网络信息,向网络设备发送第一栅格的标识以及与第一栅格相关的第二SL网络信息,用于网络设备进行网络资源的分析,得到网络资源分析结果。由于接入网设备提供的是基于栅格粒度的SL网络信息,进而使得网络设备可以基于栅格粒度的网络资源分析结果,使得接入网设备可以根据该网络资源更准确地调整栅格覆盖范围内的UE的网络资源,进而UE可以使用适应SL通信的通信质量变化的网络资源进行SL通信,提升UE进行SL通信的效率,降低UE进行SL通信的时延,避免UE进行SL通信时出现信道拥塞的情况。并且,前述栅格的粒度可以小于小区粒度、扇区粒度等,因此,接入网设备可以根据栅格粒度的网络资源分析结果,基于栅格粒度调整UE的网络资源,提高调整UE的网络资源的精度,实现对UE的网络资源的更准确地调整。
在一种可能的实现方式中,在上述步骤203之后,上述方法还包括:接入网设备向网络设备发送第一请求。
其中,该第一请求用于请求获取至少一个栅格的网络资源分析结果。并且,该第一请求中可以携带该至少一个栅格的信息。例如,该第一请求中可以携带该至少一个栅格的标识、覆盖范围等信息。
其中,该至少一个栅格的网络资源分析结果为针对该至少一个栅格的网络资源的分析结果。该至少一个栅格可以位于该接入网设备的覆盖范围内。
在一种可能的实现方式中,上述的第一请求中还携带有上述步骤203中的第二SL网络信息。
在另一种可能的实现方式中,上述步骤203中的,接入网设备向网络设备发送上述第二SL网络信息的具体方式可以为:接入网设备向网络设备发送第一请求。
其中,该第一请求用于请求获取至少一个栅格的网络资源分析结果。并且,该第一请求中携带该至少一个栅格的信息,以及上述步骤203中的第二SL网络信息。
在一种可能的实现方式中,在上述步骤203之后,或者,在接入网设备向网络设备发 送上述第一请求之后,上述方法还包括:
接入网设备接收来自网络设备的N个栅格中的至少一个栅格的网络资源分析结果;
当该网络资源分析结果满足第一预设条件时,接入网设备向该至少一个栅格覆盖范围内的UE发送SL无线承载配置;或者,
当该网络资源分析结果满足第一预设条件时,接入网设备根据该网络资源分析结果,为该至少一个栅格范围内的UE分配网络资源。
其中,该至少一个栅格的网络资源分析结果可以包括:该至少一个栅格中的SL通信支持的QoS等级,该至少一个栅格中的SL通信的拥塞程度、该至少一个栅格中的SL通信满足的QoS关键性能指标(key performance indicator,KPI)或者调整指示信息等。
具体地,该QoS等级可以包括PC5服务质量标识(PC5QoS identifier,PQI)。该PQI可以由多个QoS参数组合而成,例如,时延、丢包率、优先等级等。
其中,该至少一个栅格中SL通信的拥塞程度可以用于表征该至少一个栅格中SL通信的拥塞情况。网络设备可以根据该至少一个栅格中进行V2X业务的UE的数量或者信道占用量等确定该至少一个栅格中SL通信的拥塞程度。更进一步地,网络设备还可以结合与信道质量相关的参数,例如,SINR、接收功率、BLER等参数,确定该至少一个栅格中SL通信的拥塞程度。
其中,QoS KPI可以包括:时延或丢包率等。具体地,该时延可以包括该至少一个栅格中每个栅格支持的平均时延或最大时延等。丢包率可以包括:该至少一个栅格覆盖范围内的数据传输的最大丢包率或平均丢包率等。
其中,调整指示信息可以是资源调整指示信息,用于指示该至少一个栅格覆盖范围内的UE在进行SL通信时使用的网络资源需要调整。
其中,该第一预设条件可以为:网络资源分析结果中的参数值处于第一预设范围内,或者,网络资源分析结果包括上述的资源调整指示信息,不予限制。例如,若网络资源分析结果中携带至少一个栅格范围中进行SL通信支持的QoS等级,对应的,第一预设条件包括:该至少一个栅格覆盖范围内的SL通信当前支持的QoS等级低于该至少一个栅格范围内的UE的V2X业务的QoS等级。再例如,第一预设条件包括:该网络资源分析结果中携带有上述的资源调整指示信息。
其中,在接入网设备向该至少一个栅格覆盖范围内的UE发送SL无线承载配置情况下,该SL无线承载配置可以包括UE可用的网络资源的信息,例如,UE可用的PC5资源的频率信息、时域信息,以及UE可用的PC5资源中支持V2X业务数据传输的接口信息(例如,接口的类型或标识等)等。进一步地,UE可以根据该SL无线承载配置中携带UE可用的网络资源的信息,选择可用的网络资源。可以理解为,接入网设备可以向该至少一个栅格覆盖范围内的UE发送SL无线承载配置,用于通知UE哪些PC5资源可用,UE可以根据该SL无线承载配置,选择可用的PC5资源进行SL通信。
其中,在接入网设备接入网设备根据该网络资源分析结果,为该至少一个栅格范围内的UE分配网络资源的情况下,接入网设备可以通过控制信道将为该至少一个栅格覆盖范围内的UE分配的网络资源的信息发送至该至少一个栅格覆盖范围内的UE。具体地,接入网 设备可以根据网络资源分析结果中携带的至少一个栅格范围中进行SL通信支持的QoS等级、SL通信的拥塞程度、SL通信满足的QoS KPI等,从该至少一个栅格覆盖范围内的网络资源中,确定该至少一个栅格覆盖范围内与UE的V2X业务的通信参数对应的网络资源,并为该至少一个栅格覆盖范围内的UE分配网络资源。
具体地,为该至少一个栅格覆盖范围内的UE分配的网络资源的信息可以包括:接入网设备为UE分配的网络资源的频段信息、时域信息,以及支持传输V2X业务数据的接口信息(例如,接口的类型或标识)等信息。进一步地,UE根据接收到的来自接入网设备的网络资源的信息,更新UE当前的网络资源配置,进而UE使用接入网设备分配的网络资源进行SL通信。
例如,当接入网设备根据网络资源结果,确定某一频段出现信道拥塞的情况,则接入网设备在为UE分配网络资源时,可以避开出现信道拥塞的频段,从而可以避免UE在出现信道拥塞的频段进行SL通信,降低UE进行SL通信的时延,提高UE进行SL通信的效率。
又例如,若网络资源分析结果中携带上述的资源调整指示信息,则接入网设备根据该至少一个栅格中每个栅格的网络资源,为该每个栅格覆盖范围内的UE分配进行SL通信时使用的网络资源,使得上述每个栅格覆盖范围内的UE进行SL通信的网络资源可以由接入网设备分配,实现接入网设备基于栅格粒度对栅格覆盖范围内的UE的SL通信的网络资源进行调度,避免因UE自行选择网络资源而导致的信道拥塞。

基于上述图2-5提供的数据处理的方法,下面对本申请提供的数据处理的方法进行更进一步地说明。
601、接入网设备进行地图栅格化。
其中,由接入网设备基于地图的信息,对预设范围进行栅格划分,得到预设范围内的N个栅格的信息,N为大于或等于1的正整数。其中,步骤601中的进行地图栅格化,可以参阅上述步骤202中方式二中的相关描述。
具体地,接入网设备在进行地图栅格化之后,得到N个栅格的信息。该N个栅格的信息可以参阅上述步骤201中的相关描述。
其中,该N个栅格中的每个栅格都有对应的标识,一个栅格可以与一个标识一一对应。每个栅格的标识可以是接入网设备在划分栅格时,即为每个栅格分配;也可以是在栅格划分完成之后,接入网设备再为每个栅格分配标识。具体地,每个栅格的标识的分配方式可以是按照预设的规则进行分配。例如,可以是按照栅格划分的顺序为每个栅格分配标识,也可以是随机为每个栅格分配标识,还可以是按照每个栅格的排列顺序为每个栅格分配标识等等。
其中,预设范围可以是接入网设备下的小区覆盖范围,也可以是接入网设备下的扇区覆盖范围,还可以是由接入网设备或者其他网元根据预设规则基于地图划定的范围,例如,该预设范围可以是地图上的道路区域。
其中,该N个栅格可以是接入网设备按照预设的大小对预设范围进行划分得到。例如,接入网设备可以按照预设长度、宽度或高度(海拔)等,对道路进行划分,得到N个栅格。该N个栅格中的每个栅格的覆盖范围可以小于预设范围。例如,每个栅格的覆盖范围可以小于接入网设备下的一个或多个小区的覆盖范围,或者,每个栅格的覆盖范围的大小小于接入网设备下的小区的平均覆盖范围大小等。
需要说明的是,每个栅格的形状可以是矩形、圆形、多边形等,每个栅格的形状可以相同,也可以不相同,具体可以根据实际应用场景进行调整。
在一个示例中,以该预设范围为地图中的道路为例进行说明。如图7A所示,接入网设备可以基于地图信息的道路信息进行栅格化处理,将道路划分为多个栅格。可以将道路的 宽度作为每个栅格的宽度,每个栅格的长度可以根据运营商的设定确定。可以理解为,接入网设备将地图上的道路进行分段,每一段道路即为一个栅格,每一段道路的长度可以由运营商设定。当栅格的宽度为道路的宽度,该宽度的值在不同的场景可能不同。例如,城市道路的车道宽度为3.5米,交叉路口分流车道每车道为2.3-2.5米,干线公路(包括高速公路)每车道为3.75米,路肩(高速公路紧急停车带)为1.5-2.5米等。并且,可能存在高架道路、隧道等场景。因此,在一些具体的应用场景中,每个栅格的覆盖范围信息还可以包括海拔。
在一个示例中,以上述预设范围为一个或多个基站下的小区为例进行说明。如图7B所示。其中,以一个基站为例,该基站下包括一个或多个小区,此处以三个小区进行说明。该基站可以对该三个小区的覆盖范围进行划分,得到多个栅格。其中,一个小区可以划分为一个或多个栅格,每个栅格的覆盖范围的大小不大于该基站下最小小区的覆盖范围的大小。
在一个示例中,以上述预设范围为一个或多个基站下的扇区为例进行说明。基站也可以基于其覆盖范围内的扇区的覆盖范围进行划分,将一个扇区划分为一个或多个栅格。如图7C所示。其中,一个基站下可以包括一个或多个扇区,此处以三个扇区进行说明。该基站可以对该三个扇区的覆盖范围进行划分,得到多个栅格。其中,一个扇区可以划分为一个或多个栅格,每个栅格的覆盖范围的大小不大于该基站下最小扇区的覆盖范围的大小。
在一种可能的实现方式中,当接入网设备为一个或多个基站时,接入网设备在划分并得到N个栅格的信息之后,可以将每个栅格与一个或多个基站下的一个或多个小区进行匹配。然后将栅格的信息保存至对应的小区的数据中。例如,小区A覆盖范围内包括栅格1、栅格2、栅格5,小区B覆盖范围内包括栅格3、栅格4以及栅格6,可以将栅格1、栅格2以及栅格5的标识保存至小区A的数据中,可以将栅格3、栅格4以及栅格5的标识保存至小区B的数据中等。此外,也可以由其他网元,例如,AMF实体、NEF实体等,对N个栅格与前述一个或多个小区进行匹配,过程与接入网设备对N个栅格与前述一个或多个小区进行匹配的方式类似,不再赘述。
在另一种可能的具体的应用场景中,在3GPP TS 36.331(5.10.13.2)中,基于地图进行了区域划分,得到一个或多个分区(zone)。然后可以将PC5资源与zone对应起来,例如,将PC5资源保存至对应的zone的相关数据中,具体步骤请参阅相关标准。本申请实施例中,可以由接入网设备、PCF实体或网络设备等,将栅格与zone进行匹配,将栅格与zone对应起来。具体地,可以将上述N个栅格中的每个栅格所处的zone的信息保存在每个栅格的信息中,或者,将每个栅格的信息,保存至每个栅格所处的zone的信息中等。
其中,本申请提供的栅格的覆盖范围的大小小于zone的平均覆盖范围的大小,或者,本申请提供的栅格的覆盖范围的大小小于zone的最小覆盖范围的大小。可以理解为,本申请实施例中基于地图划分得到的栅格,可以是zone的子集。例如,如图8所示,一个zone可以分为多个栅格。其中,每个栅格都有对应的PC5资源。并且,每个zone都有对应的zone标识号(identification,ID)。每个栅格的标识可以与zone ID关联起来。例如,每个栅格的标识中可以包含对应分区的zone ID。当后续需要对zone的覆盖范围进行调整 时,可以以栅格为粒度对分区的覆盖范围进行调整。如图9所示,相对于图8,图9中的一个或多个栅格,可以从zone A划分到zone B中。在对zone的覆盖范围进行调整时,只需要对zone内的栅格的标识进行调整,例如,增加或删除zone对应的栅格的标识等,而不需要重新对每个zone的经度以及纬度或长度等进行重新调整。可以降低调整zone的复杂度。
在一种具体的实现方式中,步骤601之后,上述方法还包括:接入网设备将该N个栅格的信息发送至其他网元,例如,PCF实体、数据分析实体、NWDAF实体或AF实体等,不予限制。
可选地,步骤601可以替换为步骤6011。
6011、PCF实体进行地图栅格化。
其中,上述步骤601中地图栅格化的步骤,也可以由PCF实体执行。PCF实体进行地图栅格化的步骤与步骤601中接入网设备进行地图栅格化的步骤类似,将步骤601中的接入网设备替换为PCF实体即可,不再赘述。
在一种具体的实现方式中,在步骤6011之后,上述方法还包括:PCF实体将该N个栅格的信息发送至其他网元,例如,接入网设备、NWDAF实体、数据分析实体或AF实体等,不予限制。
可选地,步骤601可以替换为步骤6011。
6012、AF实体进行地图栅格化。
上述步骤601中地图栅格化的步骤也可以由AF实体执行。AF实体进行地图栅格化的步骤与步骤601中接入网设备进行地图栅格化的步骤类似,将步骤601中的接入网设备替换为AF实体即可,不再赘述。
在一种具体的实现方式中,在步骤6012之后,上述方法还包括:AF实体将该N个栅格的信息发送至其他网元,例如,接入网设备、NWDAF实体、数据分析实体或PCF实体等,不予限制。
602、UE向接入网设备上报第一SL网络信息。
其中,第一SL网络信息可以参阅上述步骤202中的相关描述。
其中,UE可以通过无线资源控制(radio resource control,RRC)信令,向接入网设备上报该第一SL网络信息。
其中,UE上报第一SL网络信息,有多种方式,如下所述。
方式一:UE可以周期性地向接入网设备上报第一SL网络信息。
其中,上报第一SL网络信息的周期可以由PCF实体写入下发给UE的配置信息中,UE从该配置信息中读取该上报周期,然后根据该上报周期上报第一SL网络信息。或者,接入网设备在向UE下发的信令中,携带指示UE周期性向接入网设备上报第一SL网络信息的指示,以及上报周期,UE可以根据该信令,根据上报周期,周期性地向接入网设备上报第一SL网络信息。
例如,在UE向接入网设备或PCF实体发起V2X业务请求时,或者在UE周期性地进行配置更新或注册更新等流程中,PCF实体可以通过AMF实体向UE下发配置信息,该配置信 息中可以携带UE上报第一SL网络信息的周期。
又例如,接入网设备在向UE下发的无线资源控制(radio resource control,RRC)信令时,该RRC信令中携带指示UE周期性向接入网设备上报第一SL网络信息的指示,以及上报周期。
因此,在本方式中,UE可以周期性地上报第一SL网络信息,例如,UE每分钟向接入网设备上报f1次第一SL网络信息,使得接入网设备可以周期性获取到第一SL网络信息。进而,接入网设备也可以周期性地向网络设备发送第二SL网络信息,并周期性地接收来自网络设备的网络资源分析结果,从而实现接入网设备周期性地对栅格覆盖范围内的UE的网络资源的调整或分配。进一步地,使UE可以使用调整或分配的网络资源进行SL通信,提高UE进行SL通信的效率,降低UE进行SL通信的时延。
方式二:UE根据触发条件上报第一SL网络信息。
其中,接入网设备在向UE下发的信令中携带触发UE向接入网设备上报第一SL网络信息的触发条件的信息。
其中,该触发条件可以包括:CBR低于预设门限值,或者,当前信道质量无法满足当前通信需求,例如,UE进行SL通信的时延高于第一阈值,或UE进行SL通信的丢包率高于第二阈值等,无法满足V2X业务的需求。
具体地,接入网设备可以在向UE下发的RRC信令中携带该触发条件的信息。
因此,在本方式中,当UE确定CBR低于预设门限值,或者,UE监测到当前信道质量无法满足当前通信需求时,即可向接入网设备上报第一SL网络信息,使得接入网设备可以及时获取到UE进行SL通信时的通信质量的变化。
方式三:接入网设备在需要获取到第一SL网络信息时,直接向UE下发指示UE上报第一SL网络信息的上报指示信息。
进一步地,UE在接收到来自接入网设备的上报指示信息之后,即可向接入网设备上报第一SL网络信息。
因此,在方式三中,接入网设备可以根据需求通知UE上报第一SL网络信息,可以减少UE发送的数据量,降低UE的信令开销。
此外,在步骤602之后,上述方法还包括:第一SL网络信息中可以携带UE的位置信息,接入网根据该位置信息,确定UE处于第一栅格。例如,第一SL网络信息中携带UE所在位置的经度以及纬度,接入网设备可以根据UE所在位置的经度以及纬度,与上述每个栅格的经度以及纬度坐标,或者将上述第一SL网络信息中携带UE所在位置的经度以及纬度转换为平面坐标,与上述每个栅格的经度以及纬度经转换后的平面坐标进行对比,确定UE处于第一栅格中,该第一栅格包括于上述的N个栅格。
603、接入网设备进行数据预处理。
其中,本申请实施例中的步骤603为可选步骤。
接入网设备在接收到UE发送的第一SL网络信息之后,可以对该第一SL网络信息进行预处理,得到第二SL网络信息。
其中,预处理的具体步骤,以及第二SL网络信息可以参阅上述步骤203中的相关描述。
在一个示例中,若存在两个UE在第一频段、第一栅格以及第一时间段向接入网设备上报SL通信的第一SL网络信息,接入网设备可以对该两个UE在第一频段、第一栅格以及第一时间段上报的第一SL网络信息进行预处理,例如,对第一SL网络信息所包括的数据进行加权、平均等处理,从而得到预处理SL网络信息。因此,本申请实施例中,可以通过接入网设备对第一SL网络信息的预处理,降低第一SL网络信息的数据冗余量,提高网络设备进行数据分析的效率。
在一个示例中,若同一栅格中,存在多个UE上报其当前使用的或监测到的CBR,接入网设备将多个UE上报的CBR进行加权平均或其他的量化操作,得到每个栅格对应的一个CBR,从而降低同一栅格的CBR的冗余。
在一种可能的实现方式中,若存在多组第一SL网络信息,该多组第一SL网络信息中的每一组第一SL网络信息中可能携带对应的UE的不同的信息,例如,每个UE的位置的信息、每个UE执行的V2X业务的信息等,则针对每组第一SL网络信息中不同的信息,可以无需作预处理,直接将该信息包括于第二SL网络信息即可。
在一种可选的实施方式中,接入网设备周期性地对第一SL网络信息进行预处理,且对第一SL网络信息进行预处理的周期通常小于前述步骤602中UE上报第一SL网络信息的周期。例如,接入网设备可以每分钟对第一SL网络信息进行f2次预处理,该f2小于上述步骤602中的f1。
在另一种实现方式中,当数据分析实体独立于接入网设备部署时,步骤603也可以由数据分析实体执行,接入网设备在接收到第一SL网络信息之后,将该第一SL网络信息发送给数据分析实体。数据分析实体对第一SL网络信息进行预处理的过程与接入网设备对第一SL网络信息进行预处理的步骤类似,不再赘述。

其中,接入网设备向网络设备发送的SL网络性能预测请求,即上述步骤203中所述的第一请求,具体参阅上述步骤203中的相关描述,此处不再赘述。
在一种可能的实现方式中,接入网设备可以通过同一消息发送SL网络性能预测请求、第一栅格的标识以及第二SL网络信息。
具体地,步骤605,可以理解为,若接入网设备需要对某些区域的SL网络性能进行预测时,可以将第二SL网络信息以及与需要进行SL网络性能预测的区域所属的第一栅格的标识发送至网络设备,以向网络设备请求获取至少一个栅格的网络资源分析结果,该至少一个栅格可以是第一栅格或者第一栅格及其附近的栅格。该网络资源分析结果可以用于接入网设备调整或分配UE所使用的网络资源。
在一种具体的实现方式中,接入网设备可以周期性地向网络设备发送SL网络性能预测请求,以请求至少一个栅格的网络资源分析结果,实现对该至少一个栅格内的UE所使用的 网络资源的实时调控。例如,接入网设备可以每分钟向网络设备发送f3次SL网络性能预测请求,f3小于上述步骤603中的f2。并且,接入网设备在发送SL网络性能预测请求时,携带当前周期内的第二SL网络信息,该第二SL网络信息请参阅上述步骤203中的相关描述。
在另一种具体的实现方式中,接入网设备可以根据触发事件向网络设备发送SL网络性能预测请求。该触发事件可以包括:UE向接入网设备请求分配网络资源,或者UE上报的CBR的值大于预设值,或者UE上报的道路信息车辆密度的值大于预设的车辆密度值等等。
具体地,当接入网设备可以通过同一消息发送SL网络性能预测请求、第一栅格的标识以及第二SL网络信息。其中,第二SL网络信息可以是前述步骤602中的第一SL网络信息,也可以是对第一SL网络信息进行预处理后的SL网络信息。
示例性地,对预处理后的SL网络信息与未处理的第一SL网络信息这两种场景进行示例性说明。
场景一、接入网设备向网络设备发送预处理后的SL网络信息。
具体地,当接入网设备向网络设备通过同一消息发送SL网络性能预测请求、第一栅格的标识以及第一SL网络信息经处理后的数据时,该消息的具体内容可以参阅表1。
表1
其中,接入网设备向网络设备请求的内容,即可以理解为SL网络性能预测请求,可以包括至少一栅格(包括表1中第一栅格于第一栅格附近的栅格)覆盖范围下SL通信支持的QoS等级,或者至少一栅格覆盖范围下的SL通信的拥塞程度等。
表1中的第一栅格的信息以及第一栅格附近栅格的信息,即可以包括第一栅格的标识以及第二SL网络信息。第一栅格附近栅格可以理解为与第一栅格相邻的栅格。
其中,第一栅格的信息可以包括时间戳、第一栅格的ID、UE进行SL通信的频段、信道质量参考信息与CBR信息(预处理后的数据)等。可选地,第一栅格的信息还包括第一栅格下的UE数量、该第一栅格覆盖范围内的UE的UE ID、第一栅格覆盖范围内UE的移动轨迹、第一栅格覆盖范围内的UE的V2X业务信息(例如,UE正在进行的V2X业务、V2X业务的信道占用量或者V2X业务的数据包的优先级等,参阅上述步骤202中的相关描述)、UE感知到的道路信息(例如,局部交通流密度、车辆行驶速度、温度、湿度、可见度等,参阅上述步骤202中的相关描述)等信息中的一项或者多项。其中,UE进行SL通信的频段、信道质量参考信息与CBR信息为预处理后的数据,预处理步骤参阅上述步骤203中的相关描述。第一栅格附近的栅格的信息与第一栅格的信息类似,不再赘述。
本场景一中,接入网设备可以向网络设备发送预处理后的SL网络信息,可以减少发送的数据的冗余量,提高数据发送效率。并且,网络设备在接收到预处理后的SL网络信息,因预处理后的SL网络信息的数据量少于未经预处理的SL网络信息的数据量,因此,网络设备可以基于更少的SL网络信息得到网络资源分析结果,可以减少网络设备的工作量,提高网络设备的工作效率。
场景二、接入网设备向网络设备发送未经预处理的SL网络信息。
当接入网设备向网络设备通过同一消息发送SL网络性能预测请求、第一栅格的标识以及未经预处理的第一SL网络信息时,该消息的具体内容可以参阅表2。
表2
其中,表2中所包括的内容与表1中所包括的内容类似,对于类似的内容,不作赘述。区别在于,表2中所携带的第一栅格以及第一栅格附近的栅格中每个栅格覆盖范围内的UE进行SL通信的频段、信道质量参考信息与CBR信息,为未经预处理的数据。
本场景二中,若接入网设备向网络设备发送未经预处理的SL网络信息,将可能携带与第一栅格相关的大量的第一SL网络信息。网络设备可以根据未经预处理的SL网络信息,更准确地获取到每个栅格下的网络资源的使用情况。在实际应用中,在发送SL性能预测请求时,SL网络性能消息中所携带的数据越准确,后续得到的网络资源分析结果也就越准确。
需要说明的是,本申请实施方式中的步骤605为可选步骤,即可以不执行步骤605,也 可以执行步骤605,不予限制。
可选地,上述步骤605也可以替换为6051。
6051、AF实体向网络设备发送SL网络性能预测请求。
上述步骤605也可以由AF实体执行。
其中,AF实体向网络设备发送的SL网络性能预测请求,即上述步骤502中的第二请求。该SL网络性能预测请求用于向网络设备请求至少一个栅格的网络资源分析结果。
其中,AF实体可能存在无法获取到至少一个栅格下的UE的SL网络信息的情况,因此,AF实体向网络设备发送的SL网络性能预测请求可以不携带第二SL网络信息,由接入网设备将第二SL网络信息发送至网络设备。
具体地,AF实体向网络设备发送SL网络性能预测请求的方式可以参阅上述步骤605中接入网设备向网络设备发送SL性能预测请求的方式。
一种具体的实现方式中,若AF实体上保存有N个栅格的信息,则AF实体向网络设备发送的SL网络性能预测请求中可以携带至少一个栅格的信息,例如,该至少一个栅格的标识、覆盖范围等。
另一种具体的实现方式中,当AF实体上未保存N个栅格的信息,则AF实体向网络设备发送的SL网络性能预测请求中,可以携带需要获取的网络资源分析结果对应的位置信息。例如,SL网络性能预测请求可以携带:请求预测的区域的经度以及纬度,或者,UE的单条或者多条路径的信息,或者,请求预测的范围的几何图形区域的坐标信息等。网络设备可以根据该SL网络性能预测请求中携带的UE的位置信息,确定AF实体请求获取的网络资源分析结果对应的至少一个栅格。因此,即使AF实体上不包括N个栅格的信息,也可以向网络设备发送所请求的区域的位置信息,实现向网络设备请求获取网络资源分析结果。
606、网络设备进行数据分析。
其中,本申请实施例中的步骤606可以参阅上述步骤303,此处不再赘述。
其中,触发网络设备进行数据分析的方式有多种,如下所述。
方式一:网络设备可以是在步骤605或6051之后,由SL网络性能预测请求触发网络设备进行数据分析。
其中,在方式一中,网络资源分析结果中所包括的内容,可以根据SL网络性能预测请求中所携带的请求的内容的不同而不同。
例如,若SL网络性能预测请求用于请求网络设备分析SL通信的拥塞情况,则该网络资源分析结果中携带SL通信的拥塞程度。若SL网络性能预测请求用于请求网络设备分析SL通信支持的QoS等级,则网络资源分析结果中可以包括SL通信支持的QoS等级。若SL网络性能预测请求用于请求网络设备分析SL通信中的部分QoS参数指标,则网络资源分析结果中可以包括,该至少一个栅格的可以满足V2X业务需求的QoS参数指标的指示,例如,网络资源分析结果可以包括时延或丢包率等指标,或者,网络资源分析结果可以直接包括是否满足V2X业务的QoS指标的指示等。
在一种可能的场景中,当SL网络性能预测请求为AF实体发送,而AF实体上并未保存上述N个栅格的信息,则SL网络性能预测请求中携带的是需要请求的位置的信息,网络设 备在接收到SL网络性能预测请求之后,根据该SL网络性能预测请求中携带的位置信息,确定该位置信息对应的至少一个栅格。进而对该至少一个栅格的网络资源进行分析,得到网络资源分析结果。
方式二:在步骤604之后,即可进行数据分析。
在方式二中,若接入网设备周期性地向网络设备发送第一栅格的标识以及与第一栅格相关的第二SL网络信息,则相应地,网络设备也可以周期性地基于该第一栅格的标识以及与第一栅格相关的第二SL网络信息对至少一个栅格的网络资源进行分析,得到至少一个栅格的网络资源分析结果。网络设备对至少一个栅格的网络资源进行分析的周期,可以根据接入网设备发送第一栅格的标识以及与第一栅格相关的第二SL网络信息的周期进行调整。
在一种示例中,接入网设备可以周期地向网络设备发送SL网络性能预测请求以及预设时间段内的第二SL网络信息。例如,接入网设备可以向网络设备发送5分钟内的第二SL网络信息。以使得网络设备可以基于SL网络性能预测请求以及预设时间段内的第二SL网络信息,得到该至少一个栅格的网络资源分析结果。该网络资源分析结果中可以包括未来预设时间段内该至少一个栅格覆盖范围内的SL通信的通信质量的信息。具体地,该网络设备可以根据预设算法,例如,卡尔曼滤波算法、神经网络算法等,将预设时间段采集到的第二SL网络信息作为输入,输出该至少一个栅格的网络资源分析结果,该网络资源分析结果中可以包括未来预设时间段内该至少一个栅格覆盖范围内的SL通信的通信质量的信息。该预设时间段可以由网络设备根据该预测算法确定,也可以由接入网设备直接确定。
因此,接入网设备可以向网络设备发送SL网络性能预测请求以及预设时间段内的第二SL网络信息,请求该至少一个栅格的网络资源分析结果,使得接入网设备可以基于预测得到的未来预设时间段内该至少一个栅格的网络资源分析结果,调整UE的网络资源。可以理解为,通过卡尔曼滤波算法或者神经网络算法等,基于栅格的粒度实现对SL通信的通信质量的分析或预测,进而可以基于对SL通信的通信质量的分析或预测的结果,准确地调整UE的网络资源,避免UE在进行SL通信时出现信道拥塞的情况。
607、网络设备向PCF实体发送网络资源分析结果。
其中,网络设备在获得至少一个栅格的网络资源分析结果之后,可以将该至少一个栅格的网络资源分析结果发送至PCF实体。
具体地,若网络设备周期性地对至少一个栅格的网络资源进行分析,则网络设备可以周期性地向PCF实体发送网络资源分析结果。
需要说明的是,本申请实施例中的步骤607为可选步骤,即网络设备也可以不向PCF实体发送至少一个栅格的网络资源分析结果。
608、网络设备向AF实体发送网络资源分析结果。
其中,网络设备在获得至少一个栅格的网络资源分析结果之后,可以将该至少一个栅格的网络资源分析结果发送至AF实体。
具体地,触发网络设备向AF实体发送网络资源分析结果的方式有多种,如下所述。
方式一:网络设备周期性地向AF实体发送网络资源分析结果。例如,若网络设备周期性地对至少一个栅格的网络资源进行分析,则网络设备可以周期性地向AF实体发送网络资 源分析结果。
方式二:网络设备的接收到来自AF实体的SL网络性能预测请求,将该网络资源分析结果发送至AF实体。
更具体地,网络设备可以通过NEF实体,将该网络资源分析结果转发至AF实体。
609、网络设备向接入网设备发送网络资源分析结果。
其中,网络设备在获得至少一个栅格的网络资源分析结果之后,可以将该至少一个栅格的网络资源分析结果发送至接入网设备。
具体地,触发网络设备向接入网设备发送网络资源分析结果的方式有多种,如下所述。
方式一:网络设备周期性地向接入网设备发送网络资源分析结果。例如,若网络设备周期性地对至少一个栅格的网络资源进行分析,则网络设备周期性地向接入网设备发送网络资源分析结果。
方式二:接入网设备向网络设备发送SL网络性能预测请求,网络设备将该网络资源分析结果发送至接入网设备。
610、接入网设备向UE发送网络资源的信息。
其中,该网络资源的信息为UE可用的网络资源的信息,或者,接入网设备为UE分配的网络资源的信息。当该网络资源的信息为UE可用的网络资源的信息时,该网络资源的信息可以由接入网设备通过SL无线承载配置向UE发送。当该网络资源信息为接入网设备为UE分配的网络资源的信息时,可以由接入网设备直接向该UE发送网络资源的信息。
其中,在接入网设备接收到来自网络设备的至少一个栅格的网络资源分析结果之后,当该网络资源分析结果满足第一预设条件时,接入网设备向该至少一个栅格覆盖范围内的UE发送SL无线承载配置;或者,当该网络资源分析结果满足第一预设条件时,接入网设备根据网络资源分析结果,为该至少一个栅格覆盖范围内的UE分配网络资源,并向UE发送分配的网络资源的信息。
步骤610可以参阅上述步骤203的相关描述,下面以一些具体的场景对步骤610进行更详细的说明。
例如,网络资源分析结果中携带至少一个栅格范围中的SL通信支持的QoS等级。对应的,第一预设条件为该网络资源分析结果中携带的QoS等级低于预设QoS等级。因此,当网络资源分析结果满足第一预设条件时,该至少一个栅格下的UE需要调整进行SL通信所使用的网络资源。接入网设备可以向该至少一个栅格下的UE下发SL无线承载,该SL无线承载中可以包括UE可用的网络资源的信息,使UE可以根据该SL无线承载选择可用的网络资源进行SL通信。
其中,接入网设备可以通过RRC信令,或者,***信息块(system information block,SIB)消息,将该SL无线承载配置发送至UE。
通常,接入网设备可以向该至少一个栅格覆盖范围内的UE发送SL无线承载配置,通知UE可用的PC5资源。具体地,接入网设备可以根据每个UE的V2X业务的通信参数中所包括的PC5授权信息或者QoS参数等,为UE配置对应的PC5资源。例如,UE的QoS等级越高,则为UE分配的PC5资源也就更多;或者,UE被授权使用的PC5资源越多,则为UE 分配的可用的PC5资源也就更多。
又例如,若网络资源分析结果中携带表征至少一个栅格中的拥塞程度的值,第一预设条件可以为指示至少一个栅格中的拥塞程度的值超过预设值。则当该值超过预设值之后,接入网设备确定该网络资源分析结果满足第一预设条件,可以理解为至少一个栅格中的SL通信的拥塞程度较高,需要对该至少一个栅格覆盖范围内的UE在进行V2X通信业务时使用的网络资源进行调整。接入网设备可以根据该网络资源结果,为UE分配进行SL通信的网络资源,并将为UE分配进行SL通信的网络资源的信息下发至UE。进一步地,UE可以根据接入网设备为UE分配进行SL通信的网络资源的信息,更新网络资源配置,使用接入网设备为UE分配进行SL通信的网络资源进行SL通信。
在一种示例中,UE在进行V2X业务时可以使用的直接通信的频段为5905-5925MHz频段,也可以理解为,5905-5925MHz为LTE-V2X应用的车联网直接通信的工作频段。当道路上的车辆节点密度过大时,20MHz带宽的直通工作频段很容易发生信道拥塞的情况。当接入网设备确定网络资源分析结果满足第一预设条件时,可以理解为,当前SL通信的通信质量较差,或者出现了信道拥塞的情况。接入网设备可以向UE发送SL无线承载配置,通知UE可用的PC5资源,以使UE可以选择PC5资源进行通信,或者,接入网设备可以根据网络资源分析结果,为UE分配PC5资源。因此,本示例中,UE可以通过可用的PC5资源或分配的PC5资源进行SL通信,提高UE进行SL通信的通信效率,避免UE在进行SL通信时出现信道拥塞的情况。
通常,SL无线承载配置也可以理解为预配置的SL无线承载,即接入网设备根据网络设备分析得到的网络资源分析结果,预测出可能出现的SL通信的通信质量差或信道拥塞等情况,从而通过预配置的SL无线承载,避免UE在进行SL通信时出现通信质量差或信道拥塞等情况。
611、PCF实体向UE发送V2X业务的通信参数。
本申请实施例中的步骤611,可以参阅上述步骤402之后的相关描述,此处不再赘述。
其中,当至少一个栅格的网络资源分析结果满足第二预设条件时,则该至少一个栅格中的网络资源的通信质量较差,可能存在时延高、传输效率低等情况。因此,当网络资源分析结果满足第二预设条件时,PCF实体可以根据网络资源分析结果,向该至少一个栅格覆盖范围内的一个或多个UE发送V2X业务的通信参数,从而实现对该至少一个栅格覆盖范围内的一个或多个UE的V2X业务的通信参数的调整。
例如,若至少一个栅格中的SL通信的通信质量较差,SL通信支持的QoS等级降低,则PCF实体可以通过下发V2X业务的通信参数,降低该至少一个栅格范围内的UE的V2X业务的QoS等级,以适应SL通信的通信质量的变化,避免出现SL通信的信道拥塞。或者,PCF实体通过向UE下发V2X业务的通信参数,调整UE进行V2X业务时使用的频段等,从而避免UE在信道质量差的频段通信,提高UE进行SL通信的通信质量,降低UE的通信时延。
又例如,若至少一个栅格中的信道通信质量较好,SL通信支持的QoS等级提高,则PCF实体也可以相应地通过下发V2X业务的通信参数提高该至少一个栅格范围内的UE的V2X业务的QoS等级,以适应SL通信的通信质量,提高UE在SL通信的通信质量。或者,PCF实 体通过向UE下发V2X业务的通信参数,调整UE进行V2X业务时使用的频段等,从而使UE在信道质量较好的频段通信,也可以提高UE进行SL通信的通信质量,降低UE进行SL通信的时延。
612、AF实体向UE发送V2X业务的QoS参数。
本申请实施例中的步骤612,可以参阅上述步骤502中的相关描述,此处不再赘述。
本步骤所指的V2X业务为AF实体为UE提供的业务。例如,车辆共享传感器信息业务,车辆周期性广播自身位置、速度等状态信息业务,车辆转发其他车辆或路边设备的信息业务等等。
具体地,网络资源分析结果可以参阅上述步骤203的相关描述。
其中,当网络资源分析结果满足第三预设条件时,可以理解为,该至少一个栅格中的网络资源的通信质量较差,可能存在传输时延高、传输效率低等情况。因此,当网络资源分析结果满足第三预设条件时,AF实体可以根据网络资源分析结果,向该至少一个栅格覆盖范围内的一个或多个UE发送V2X业务的QoS参数,该QoS参数可以用于调整UE的V2X业务的QoS参数。
因此,AF实体可以通过基于栅格粒度的网络资源分析结果,实现对UE的V2X业务的QoS参数基于栅格的粒度进行调整,实现更准确地对UE的V2X业务的QoS参数的调整。
例如,若至少一个栅格中SL通信的通信质量较差,SL通信支持的QoS等级降低,则AF实体可以向该至少一个栅格范围内的UE下发V2X业务的QoS参数,降低该至少一个栅格范围内的UE的V2X业务的QoS等级。从而避免出现SL通信的信道拥塞的情况。
又例如,若至少一个栅格中的信道通信质量较好,SL通信支持的QoS等级提高。则AF实体可以向该至少一个栅格范围内的UE下发V2X业务的QoS参数,提高该至少一个栅格范围内的UE的V2X业务的QoS等级。从而提高UE进行SL通信的通信质量,降低UE的通信时延。
在一个示例中,AF实体接收到来自网络设备的至少一个栅格的网络资源分析结果之后,若该网络资源分析结果满足第三预设条件,则可以理解为该至少一个栅格覆盖范围内的PC5资源的通信质量可能较差,或出现信道拥塞等情况。因此,AF实体可以向该至少一个栅格的覆盖范围内,进行V2X业务的UE发送V2X业务的QoS参数。使得UE可以根据该V2X业务的QoS参数,配置自身所执行的V2X业务的QoS参数。因此,AF实体可以通过调整UE的V2X业务的QoS参数,使UE的V2X业务的QoS参数更适应SL通信的通信质量,提高UE进行SL通信的通信效率,降低UE的通信时延。
在一种具体的场景中,上述步骤611中,PCF实体向UE发送的V2X业务的通信参数中所包括的QoS参数,可以由一个或多个AF实体发送至PCF实体,然后由PCF实体发送至UE。具体地,该AF实体可以为V2X业务对应的实体。PCF实体向UE发送的V2X业务的通信参数中,可以包括UE的一个或多个V2X业务的通信参数,该一个或多个V2X业务的通信参数可以包括该一个或多个V2X业务的QoS参数。该一个或多个V2X业务的QoS参数可以由一个或多个V2X业务对应的AF实体通过NEF实体发送至PCF实体,然后由PCF实体发送至UE。
因此,在本申请实施方式中,由接入网设备、PCF实体或者AF实体中的其中一个进行地图栅格化,并将栅格化得到的N个栅格的信息通知其他网元。第一栅格覆盖范围内的UE可以向接入网设备上报第一SL网络信息,接入网设备可以向网络设备发送第一栅格的标识以及与第一栅格相关的第二SL网络信息。使得网络设备可以基于N个栅格的信息、第一栅格的标识以及第二SL网络信息,获得至少一个栅格的网络资源分析结果。并将该网络资源分析结果发送至接入网设备、PCF实体和/或AF实体,使得接入网设备、PCF实体和/或AF实体,可以对UE的网络资源、V2X业务的通信参数或V2X业务的QoS参数等进行调整,避免该至少一个栅格覆盖范围内的UE出现通信质量差或因SL通信的信道拥塞而无法通信等情况。

当接入网设备为基站时,可能存在多个基站。每个基站可以对其覆盖范围内的道路进行栅格划分,多个基站进行栅格划分,即可得到N个栅格的信息。并且,基站在进行栅格划分时,每个栅格的覆盖范围的大小可以小于该基站下的最小小区的覆盖范围的大小,使得划分的栅格的粒度小于小区的粒度。或者,基站在进行栅格划分时,每个栅格的覆盖范围的大小可以小于该基站下的最小扇区的覆盖范围的大小,使得划分的栅格的粒度小于扇区的粒度。
具体地,每个栅格的形状可以是圆形、椭圆形、方形或者其他多边形等,每个栅格的形状可能并不相同。因此,每个栅格的覆盖范围信息所包括的内容也可能不同。例如,若栅格的形状为圆型,则该栅格的覆盖范围信息可以包括圆心的经度以及纬度、半径以及指示该栅格的形状为圆型的指示数据等。若栅格的形状为多边形,则该栅格的覆盖范围信息可以包括每个顶点的位置的经度以及纬度,或者,还包括指示该栅格的形状为多边形的指示数据等。

其中,在接入网设备接收到来自NWDAF实体的网络资源分析结果之后,若该网络资源分析结果满足第一预设条件。则可以理解为,在之后的某一段时间内,该至少一个栅格覆盖范围内的SL通信的通信质量差,例如,SL通信支持的QoS等级降低或信道拥塞程度高等。接入网设备可以为该至少一个栅格覆盖范围内的UE,或者,即将进入该至少一个栅格覆盖范围内的UE调整或分配PC5资源,使得UE可以使用可用的PC5资源进行通信。可以提高该至少一个栅格内的UE的通信效率,降低该至少一个栅格覆盖范围内的SL通信的信道拥塞程度。
通常,对于一些优先级较高、业务数据重要程度高或传输的数据量大的UE,接入网设备可以配置更多的PC5资源,使得可以保障这一类的UE的通信传输,提高通信传输的可靠性。
1012、PCF实体向UE下发控制策略以及V2X业务的通信参数。

可以理解为,PCF实体根据网络资源分析结果,确定在之后的某一段时间内,该至少一个栅格覆盖范围内的SL通信的通信质量变化大,例如,SL通信支持的QoS等级降低、信道拥塞程度高等。因此,PCF实体也可以向至少一个栅格覆盖范围内的UE下发控制策略以 及V2X业务的通信参数。该控制策略可以用于通知UE,在哪些时段或频段或者使用的PC5接口或Uu接口进行V2X业务的数据传输。从而避免该至少一个栅格覆盖范围内的UE在同一时段或同一频段使用相同的接口通信,以降低该至少一个栅格覆盖的SL通信的信道拥塞程度。
通常,当SL通信支持的QoS等级较低时,PCF实体可以通过向UE下发V2X业务的通信参数,降低该至少一个栅格覆盖范围内的UE的V2X业务的QoS等级,或者,降低一些传输的数据重要程度较低的UE的V2X业务的QoS等级。当SL通信支持的QoS等级较高时,PCF实体也可以通过向UE下发V2X业务的通信参数,提高该至少一个栅格覆盖范围内的UE的V2X业务的QoS等级。
