Description

信息传输方法以及相关设备
本申请要求于2020年4月10日提交中国专利局，申请号为202010281284.1，发明名称为“信息传输方法以及相关设备”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
本申请实施例涉及互联网领域，尤其涉及一种信息传输方法以及相关设备。
背景技术
随着通信需求的发展，越来越多的业务需要保证低时延的性能，比如URLLC业务需要时延在0.5毫秒之内。为了保证业务的性能，运营商需要知道当前网络的时延性能。
在现有技术中，接入网设备可以向核心网设备提供终端设备和接入网设备间进行数据传输时的时延，即时延信息。
由于终端设备和接入网设备间进行数据传输的时延是由多段时延构成的，其中一部分是需要终端设备测量的，称为终端侧时延。核心网获得时延信息时，需要知道该时延信息具体的组成部分，否则核心网获得该时延信息并不知道该时延的具体含义。而某些终端设备由于处理能力或其他原因，并不支持测量终端侧时延。所以核心网在获得时延信息时需要知道当前接入网设备提供的时延信息的具体含义。

请参阅图1.1，图1.1是本申请的实施例可以应用的通信系统的架构示意图，包括：
核心网设备101，接入网设备102，终端设备103。
核心网设备101，是指为终端提供业务支持的核心网(core network，CN)中的设备。目前，一些核心网设备的举例为：接入和移动性管理功能(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)实体等等，此处不一一列举。其中，AMF实体可以负责终端的接入管理和移动性管理；SMF实体可以负责会话管理，如用户的会话建立等；UPF实体可以是用户面的功能实体，主要负责连接外部网络。需要说明的是，本申请中实体也可以称为网元或功能实体，例如，AMF实体也可以称为AMF网元或AMF功能实体，又例如，SMF实体也可以称为SMF网元或SMF功能实体等，具体此处不做限定。
接入网设备102，是指将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。目前，一些RAN节点的举例为：继续演进的节点B(gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station， BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。另外，在一种网络结构中，接入网设备可以包括集中单元(centralized unit，CU)、或分布单元(distributed unit，DU)、或包括集中单元和分布单元的RAN设备。其中包括集中单元和分布单元的RAN设备从逻辑功能角度将协议层拆分开，部分协议层的功能放在集中单元集中控制，剩下部分或全部协议层的功能分布在分布单元中，由集中单元集中控制分布单元。
如图1.2所示，是集中单元-分布单元(CU-DU)的架构示意图。集中单元和分布单元在物理上可以是分离的也可以部署在一起。集中单元和分布单元可以根据协议层进行划分，例如其中一种可能的划分方式是：集中单元用于执行无线资源控制(radio resource control，RRC)层、服务数据适配层(service data adaptation protocol，SDAP)(本协议层是当接入网设备连接到5G核心网时才具有的协议层)、分组数据汇聚层协议层(packet data convergence protocol，PDCP)的功能，而分布单元用于执行无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层以及物理(physical，PHY)层等的功能。
可以理解，上述划分仅仅是一种举例，集中单元和分布单元也可以按照其他的方式进行划分。例如可以将集中单元或者分布单元划分为具有更多协议层的功能。例如，集中单元或分布单元还可以划分为具有协议层的部分处理功能。
在一种可能的实现方式中，将RLC层的部分功能和RLC层以上的协议层的功能设置在集中单元，将RLC层的剩余功能和RLC层以下的协议层的功能设置在分布单元。
在另一种可能的实现方式中，还可以按照业务类型或者其他系统需求对集中单元或者分布单元的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在分布单元，不需要满足该时延要求的功能设置在集中单元。
在又一种可能的实现方式中，集中单元也可以具有核心网的一个或多个功能。一个或者多个集中单元可以集中设置，也可以分离设置。例如集中单元可以设置在网络侧方便集中管理。分布单元可以具有多个射频功能，也可以将射频功能拉远设置。
应理解，集中单元和分布单元的功能可以在具体实现中可以根据需要设置，本申请实施例对此不作任何限定。集中单元的功能可以由一个实体来实现也可以由不同的功能实体来实现。在一种方式中，集中单元的功能可以进一步切分为控制面(control plane，CP)功能和用户面(user plane，UP)，即集中单元可以分为CU-UP和CU-CP。CU-CP和CU-UP可以由不同的功能实体来实现，也可以由同一功能实体来实现。CU-CP和CU-UP可以与分布单元相耦合，共同完成接入网设备的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密、完整性保护以及数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网设备的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密、完整性保护、头压缩、序列号维护以及数据传输等。还有一种可能的实现方式是PDCP-C也包含在CU-UP中。
核心网设备与集中单元(例如CU-UP和/或CU-CP)之间可以进行通信，例如，CU-CP可以代表接入网设备通过Ng接口与核心网设备进行通信。CU-UP与CU-CP之间可以进行通信，例如，通过E1接口进行通信。CU-UP与分布单元之间以及CU-CP与分布单元之间可以进行通信，例如，CU-CP可以通过F1-C(控制面)与分布单元进行通信，CU-UP可以通过F1-U(用户面)与分布单元进行通信。多个分布单元可以共用一个集中单元，一个分布单元也可以连接多个集中单元(图中未示出)。集中单元与分布单元之间可以通过接口(例如F1接口)进行通信。
终端设备103，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是指向用户提供语音和/或数据连通性的设备。例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中或者和终端设备匹配使用。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端设备的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
第五代移动通信技术(5th generation mobile network，5G)场景下，基于服务质量(quality of service，QoS)流(flow)的QoS架构如图2所示，该架构适用于新空口(new radio，NR)连接到5代核心网(5th generation core，5GC)，也适用于进化的通用移动通信陆地无线接入(evolved universal terrestrial radio access，E-UTRA)连接到5GC。对于每个UE而言，5GC为其建立一个或多个协议数据单元(protocol data unit，PDU)会话(Session)。对于每个UE而言，RAN为每个PDU会话建立一个或多个数据无线承载(data radio bearer，DRB)。
PDU会话可以理解为是终端和数据网络(data network，DN)之间提供PDU链接服务的链接。
QoS flow是指一个PDU会话内，具备相同QoS需求的数据流，其中，可以是多个具有相同QoS需求的国际互联协议(internet protocol，IP)flow。DRB可以理解为是基站和终端之间的数据承载，该数据承载中的包具备相同的转发处理。
随着通信需求的发展，越来越多的业务需要保证低时延的性能，比如超高可靠低时延通信(ultra-reliable and low latency communications，URLLC)业务需要时延在0.5毫秒之内。为了保证业务的性能，运营商需要知道当前网络的时延性能。核心网设备可以包括核心网用户面(user plane，UP)和核心网控制面(control plane，CP)。标准中引 入了服务质量监测(QoS monitoring)的功能，可以测量接入网设备与核心网用户面(比如5G核心网中的UPF)之间的传输时延以及接入网设备与终端设备之间的传输时延。核心网设备通过控制面通知接入网设备，进行启动该功能(比如控制面消息中指定了测量上行或下行或上行和下行的时延)；接入网设备收到该通知之后，接入网设备会把接入网设备与终端设备之间的时延测量结果(上行或下行或上行和下行的测量结果)发送给核心网设备。
参阅图3，图3为核心网设备测量时延信息的示意图，核心网设备的用户面在监测包对应的通用无线分组业务(general packet radio service，GPRS)用户面隧道协议(GPRS tunnelling protocol user plane，GTP-U)报头中携带一个指示信息，如：服务质量监测包指示(QoS monitoring packet indicator，QMP indicator)，指示该监测包用于测量时延信息。同时会在GTP-U报头中携带核心网设备的用户面发送该包的时刻信息(也称为时间戳)T1，时刻信息可以是指本地时间信息的形式。
接入网设备收到该监测包之后，记录接收该包的时刻信息T2。接入网设备进行接入网设备与终端设备之间的时延测量，本申请实施例中，接入网设备进行接入网设备与终端设备之间的时延测量与接入网设备收到该监测包之间并没有先后时序关系。
接入网设备在监测响应包中把接入网设备与终端设备之间的时延测量结果发送给核心网设备的用户面，在监测响应包对应的GTP-U报头中也携带一个指示信息，如：服务质量监测包指示，指示该监测响应包用于测量时延信息，且该监测响应包携带时刻信息T1，T2，以及接入网设备发送该监测响应包的时刻信息T3，并携带接入网设备与终端设备之间的时延测量结果(比如上行时延(UL delay result)，下行时延(DL delay result))。本申请实施例中，该监测响应包可能携带了上行数据包，也可能没有携带上行数据包。
核心网设备的用户面收到监测响应包，记录接收该包的时刻信息T4。
需要说明的是，接入网设备给核心网用户面设备发送的接入网设备与终端设备之间的时延测量结果可能并不是在接入网设备给和核心网设备发送的监测响应包(即携带了服务质量监测包指示、T1、T2、T3)中携带。即可能监测响应包中不包括接入网设备与终端设备之间的时延测量结果，或者接入网设备给核心网用户面设备发送的携带了终端设备与接入网设备之间的时延测量结果的包中并不携带时刻信息T1、T2、T3。
核心网设备的用户面计算接入网设备与核心网设备的用户面之间进行数据传输的上行时延、下行时延、或上行和下行时延。终端设备与核心网设备的用户面之间的上行时延为：终端设备与接入网设备之间的上行时延+接入网设备与核心网设备的用户面之间的上行时延；终端设备与核心网设备的用户面之间的下行时延为：终端设备与接入网设备之间的下行时延+接入网设备与核心网设备的用户面之间的下行时延；终端设备与核心网设备的用户面之间的来返时延为：终端设备与接入网设备之间的上行时延+终端设备与接入网设备之间的下行时延+接入网设备与核心网设备的用户面之间的来返时延；接入网设备与核心网设备的用户面之间的来返时延为：终端设备与核心网设备的用户面之间的上行时延+终端设备与核心网设备的用户面之间的下行时延。
比如：当核心网设备的用户面与接入网设备之间是时间同步的场景，接入网设备与核心网设备的用户面之间的下行时延为T2-T1，接入网设备与核心网设备的用户面之间的下 行时延为T4-T3，接入网设备与核心网设备的用户面之间的来返时延为T2-T1+T4-T3，当核心网设备的用户面与接入网设备之间是时间不同步的场景，接入网设备与核心网设备的用户面之间的来返时延为T4-T1-(T3-T2)，下行时延和上行时延为(T4-T1-(T3-T2))/2。
对于接入网设备和终端设备之间的上行时延，分为上行终端侧时延D1和上行接入网侧时延D2两个过程，参阅图4，其中，上行终端侧时延为终端设备侧的包数据汇聚协议(packet data convergence protocol，PDCP)缓冲时延。该时延对应的时间段为终端设备从PDCP的上层收到数据包到得到了发送该数据包的上行授权，该时延也包括从UE发送调度请求或随机接入到得到上行授权的时延，即上行终端侧时延D1为终端设备接收到数据至向接入网设备发送数据的时长，终端侧时延由终端设备进行测量并上报给接入网设备。
上行接入网侧时延D2包括混合自动重传输请求(hybrid automatic repeat request，HARQ)传输或重传时延D2.1，RLC侧时延D2.2，F1口时延D2.3，以及PDCP重排序时延D2.4等。其中，D2.1可以定义为从终端设备发送数据包到接入网设备成功接收该数据包的时段；D2.2可以定义为从无线链路控制(radio link control，RLC)服务数据单元(service data unit，SDU)的第一部分被正确接收到把该RLC SDU发送给PDCP层或集中单元(centralized unit，CU)的时段；D2.3可以定义为CU把一个数据包发送给分布单元(distributed unit，DU)到CU从DU收到该包的传输状态，再减去该包在DU侧的反馈时延，再除以2；D2.4可以定义为收到一个PDCP SDU到把该PDCP SDU发送给上层的时段。
参阅图5，本申请实施例中信息传输方法一个流程包括步骤501至507，具体如下：
501、核心网设备向接入网设备发送时延测量信息；
核心网设备向接入网设备发送时延测量信息，该时延测量信息指示接入网设备提供时延信息，时延信息为终端设备和接入网设备间进行数据传输时的时延。
时延测量信息可以由下述信息携带，如：协议数据单元会话资源建立请求(PDU session resource setup request)消息，协议数据单元会话资源修改请求(PDU session resource modify request)消息或资源切换请求(handover request)消息中任一个，具体消息此处不做限定。具体的可以在这些消息中的服务质量流层服务质量参数(QoS flow level QoS parameters)携带，时延测量信息具体内容可以包括服务质量监测请求(QoS monitoring request)，取值可以为上行、下行、或上行和下行，代表需要测量对应QoS flow的上行、下行、或上行和下行的时延。
502、接入网设备向核心网设备发送基于时延测量信息的响应；
接入网设备接收到时延测量信息后，接入网设备可以向核心网设备回复响应信息，该响应信息指示该接入网设备接收到时延测量信息，且支持测量接入网设备和终端设备间进行数据传输时的时延。
接入网设备根据时延测量信息回复对应的响应，如：当时延测量信息由协议数据单元会话资源建立请求(PDU session resource setup request)消息携带时，该响应可以为协议数据单元会话资源建立响应(PDU session resource setup response)消息；当时延测量信息由协议数据单元会话资源修改请求(PDU session resource modify request)消息携带时，该响应可以为协议数据单元会话资源修改响应(PDU session resource modify  response)消息；当时延测量信息由资源切换请求(handover request)消息携带时，该响应可以为切换请求确定(handover request acknowledge)消息。
可选的，接入网设备向核心网设备发送指示信息指示终端设备是否支持测量终端侧时延，或者指示时延信息中是否包含终端侧时延。在一种可实现的方式中，该指示信息可以由基于时延测量信息的响应携带。本发明并不限定该指示信息的形式，比如该指示信息指示时延信息包含终端侧时延，如果不携带该指示信息，则代表时延信息不包含终端侧时延。或者该指示信息指示终端设备支持测量终端侧时延，如果不携带该指示信息，则代表终端设备不支持测量终端侧时延。需要说明的是，终端是否支持测量终端侧时延只是本发明为了便于描述而采用的写法，但实际中可能协议只是描述终端设备是否支持时延测量。
可以理解的是，在实际运行中步骤502可以不执行，核心网设备可以默认接入网设备接收到时延测量信息，且接入网设备支持测量接入网设备和终端设备间进行数据传输时的时延。
503、核心网设备向接入网设备发送时延监测包；
在一种可实现的方式下，核心网设备可以向接入网设备发送时延监测包，该时延监测包指示接入网设备监测接入网设备和终端设备间进行数据传输时的时延，可以理解的是，在实际运行中，步骤503可以不执行，当接入网设备接收到时延测量信息，接入网设备监测接入网设备和终端设备间进行数据传输时的时延，并得到时延信息。
504、接入网设备向终端设备发送时延测量消息；
当终端设备支持测量终端侧时延时，接入网设备向终端设备发送时延测量消息，指示终端设备测量终端侧时延。
需要说明的是，终端侧时延可以是指上行终端侧时延，也可以指下行终端侧时延。上行终端侧时延可以为前面所述的D1。下行终端侧时延可以是终端设备的MAC层从接入网设备正确收到一个数据包，到把该数据包提交给PDCP层的上层的时延。
时延测量消息可以为无线资源控制(radio resource control，RRC)重配消息，即接入网设备通过RRC重配消息通知终端设备进行终端侧时延的测量，比如在RRC重配消息中的其他配置(otherconfig)或者测量配置(measConfig)中携带通知终端设备进行时延测量的信息。比如携带对数据无线承载(data radio bearer，DRB)进行时延测量的标识即携带DRB标识(identity，ID)。
可选的，接入网设备可以通知终端设备进行周期性的终端侧时延测量，并周期上报或周期性上报对应的终端侧时延周期性取值，一个周期的时长可以为200毫秒或500毫秒等，一个周期的时长本申请实施例中不做限定。
505、终端设备测量终端侧时延；
终端设备收到时延测量消息后测量终端侧时延，在一种可行的实施方式下，终端设备周期性的测量终端侧时延，一个周期的时长可以为200毫秒或500毫秒等，一个周期的时长本申请实施例中不做限定。
506、终端设备向接入网设备发送终端侧时延；
对于终端侧时延变化不大的场景，可以减少终端侧设备向接入网设备发送终端侧时延 的次数，接入网设备根据历史数据得到终端侧时延，以此减少上报占用的网络资源。
如在终端设备周期性进行终端侧时延的测量和上报时，若当前需要上报的终端侧时延值，即本周期测量到的终端侧时延值，符合预设的时延范围，预设的时延范围可以由终端设备上次上报的终端侧时延得到，如预设的时延范围为上次上报的终端侧时延的0.9倍到1.1倍或者与上次上报的终端侧时延的差别在1毫秒范围内，即如果当前需要上报的取值与上次上报的终端侧时延值的差别在一个时延范围内，则终端设备可以不上报本次测量结果，否则，终端设备上报测量到的终端侧时延。该时延范围可以由接入网设备通知终端设备(比如在时延测量信息中携带)或者通过事先通过的协议固定该时延范围，终端设备获取时延范围的方式此处不做限定。接入网设备还可以通知终端设备是否需要进行处于该时延范围的判断，即直接上报还是判断与上次上报的值的差别在一个时延范围内。
可选的，对于终端设备第一次向接入网设备发送终端侧时延，终端设备可以将该终端侧时延和一个初始值进行比较，如果当前需要上报的终端侧时延与初始值的差别在一个时延范围内，则终端设备无需上报本次测量结果，否则终端设备上报本次测量结果。该初始值可以由接入网设备通知终端设备(比如在时延测量消息中携带)或者通过事先通过的协议固定该初始值，终端设备获取初始值的方式此处不做限定。
可选的，本实施例中终端设备可以在每次上报终端侧时延时，都和初始值进行判断比较，如果当前需要上报的终端侧时延与初始值的差别在一个时延范围内，则终端设备无需上报本次终端侧时延测量结果，否则终端设备上报本次终端侧时延测量结果。
507、接入网设备向核心网设备发送时延信息。
参阅图6，图6为时延信息所在的包的部分参数示意图，接入网设备向核心网设备发送时延信息。其中，QMP为前面所述的服务质量监测包指示QMP indicator。DL Delay indicator(简写为DL delay Ind.)用于指示该包中是否包括接入网设备与终端设备之间的下行时延测量结果(Dl Delay Result)。UL Delay indicator(简写为UL delay Ind.)用于指示该包中是否包括接入网设备与终端设备之间的上行时延测量结果(UL Delay Result)。QoS flow identifier用于指示当前包是携带哪一个QoS flow的时延测量结果。DL sending Time Stamp Repeated可以为前述T1，DL received Time stamp就是前面所述T2，UL sending Time Stamp可以为前述T3。
可选的，接入网设备向核心网设备发送指示信息，指示终端设备是否支持测量终端侧时延，或者指示时延信息中是否包含终端侧时延。
在一种可实现的方式中，该指示信息可以在时延信息所在的包中携带，比如图6中的D1 indicator(简写为D1 Ind.)。D1 Ind.指示终端设备是否支持测量终端侧时延或指示时延信息中是否包含终端侧时延。指示信息的另外一种含义可能是用于指示其中的UL Delay result是否包括D1的取值。指示信息的另外一种含义可能是用于指示该包中是否携带了D1的取值，比如除了其中的UL Delay Result之外，该包中还有一部分比特来单独标识D1的取值，比如这种情况下，其中的UL Delay Result只包括前面的D2的取值。在另一种可行的方式下，由步骤502可得，指示信息还可以由基于时延测量信息的响应携带。可以理解的是，在实际运行中，接入网设备可能在其他消息中向核心网设备发送指示信息，如： 在初始用户设备消息(initial user equipment message)或用户设备无线能力信息指示(user equipment radio capability info indication)，中向核心网设备发送指示信息，指示信息的发送时机此处不做限定。
当终端设备不支持测量终端侧时延时，在一种可行的方式下，接入网设备可以通过估计得到终端侧时延的取值，或者终端设备根据其自身的能力估计出终端侧时延的取值并上报接入网设备，具体此处不做限定。
可以理解的是该指示信息的具体形式有多种，在一种可实现的方式中，指示信息包括第一指示信息和/或第二指示信息，其中，第一指示信息指示终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延，第二指示信息指示终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延，在实际运行中，指示信息可以仅包括上述第一指示信息，当核心网设备收到该第一指示信息，则确定终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延；反之，当核心网设备未收到该第一指示信息，则确定终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延。本申请实施例中不限定指示信息的具体形式。
对于接入网设备触发测量终端设备与接入网设备之间进行数据传输的时延，接入网设备可以是由于收到核心网设备或操作、管理和维护(operation，administration and maintenance，OAM)设备发送的立即最小化路测工作MDT(immediate minimization of drive tests，immediate MDT)的通知才触发通知终端设备进行时延测量。
上述实施例主要描述了指示信息由接入网设备发送的情况，可以理解的是指示信息可以由终端设备直接向核心网设备发送，指示该终端设备是否支持测量终端侧时延，或者指示时延信息中是否包含终端侧时延，参阅图7，该信息传输方法的流程包括步骤701至708，具体如下：
701、终端设备向核心网设备发送指示信息；
该指示信息指示终端设备是否支持测量终端侧时延，或者指示时延信息中是否包含终端侧时延。终端设备可以在给核心网设备的非接入层NAS消息中携带该指示信息。
可以理解的是该指示信息的具体形式有多种，在一种可实现的方式中，指示信息包括第三指示信息和/或第四指示信息，其中，第三指示信息指示终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延，第四指示信息指示终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延，在实际运行中，指示信息可以仅包括上述第三指示信息，当核心网设备收到该第三指示信息，则确定终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延；反之，当核心网设备未收到该第三指示信息，则确定终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延。本申请实施例中不限定指示信息的具体形式。
702、核心网设备向接入网设备发送时延测量信息；
703、接入网设备向核心网设备发送基于时延测量信息的响应；
704、核心网设备向接入网设备发送时延检测包；
705、接入网设备向终端设备发送时延测量消息；
706、终端设备测量终端侧时延；
707、终端设备向接入网设备发送终端侧时延；
708、接入网设备向核心网设备发送时延信息。
本实施方式(图7所示实施方式)和图5对应的实施方式类似，图5所示的实施方式指示信息可以由接入网设备向所述核心网设备发送的控制面消息(如：基于时延测量信息的响应)携带，或由所述接入网设备向所述核心网设备发送的用户面数据(时延信息所在的包)携带，而本实施方式由终端设备直接向核心网设备发送(如：步骤701)，可以理解的是，该步骤和步骤702至步骤707之间没有时序关系。本实施方式中步骤702至步骤708和图5所示实施例中步骤501至507类似，具体此处不再赘述。
MDT技术的基本思想是运营商通过签约用户的商用终端进行测量上报来部分替代传统的路测工作，实现自动收集终端设备测量的数据，以检测和优化无线网络中的问题和故障。immediate MDT是利用处于无线资源控制连接态RRC_CONNECTED的终端设备来收集终端设备测量数据。immediate MDT可由核心网设备触发(也称为基于信令的immediate MDT，核心网设备向接入网设备发送immediate MDT通知)，也可以由OAM设备触发(也称为基于管理的immediate MDT，OAM设备向接入网设备发送immediate MDT通知)。针对immediate MDT，接入网设备也可以通知终端设备进行上行时延测量。参阅图8，该信息传输方法的流程包括步骤801至805，具体如下：
801、接入网设备从核心网设备或第一网络设备接收时延测量信息；
对于基于信令的immediate MDT，核心网设备可以在初始上下行建立请求(initial context setup request)、切换请求(handover request)消息、跟踪开始(trace start)消息中携带延测量信息，具体消息此处不做限定。
对于基于管理的immediate MDT，接入网设备可以从OAM设备接收时延测量信息，接入网设备触发测量接入网设备和终端设备间进行数据传输的时延。
802、接入网设备向终端设备发送时延测量消息；
803、终端设备测量终端侧时延；
804、终端设备向接入网设备发送终端侧时延；
步骤802至804和前述图5所述实施例中步骤504至506类似，具体此处不再赘述。
805、接入网设备向第一网络设备发送时延信息。
接入网设备向第一网络设备发送时延信息。其中第一网络设备可以是OAM设备或者跟踪收集实体(trace collection entity，TCE)或其他设备。可选的，接入网设备向第一网络设备发送指示信息，指示终端设备是否支持测量终端侧时延，或者指示时延信息中是否包含终端侧时延。指示信息的另外一种含义可能是用于指示时延信息中是否携带了D1的取值，比如除了携带前面D2的取值之外，时延信息中还单独携带了D1的取值，比如这种情况下，D1和D2的取值是单独来指示的。
当终端设备不支持测量终端侧时延时，在一种可行的方式下，接入网设备可以通过估计得到终端侧时延的取值，或者终端设备根据其自身的能力估计出终端侧时延的取值并上报接入网设备，具体此处不做限定。
可以理解的是该指示信息的具体形式有多种，在一种可实现的方式中，指示信息包括第一指示信息和/或第二指示信息，其中，第一指示信息指示终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延，第二指示信息指示终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延，在实际运行中，指示信息可以仅包括上述第一指示信息，当第一网络设备收到该第一指示信息，则确定终端设备支持测量终端侧时延或者时延信息中含有所述终端侧时延；反之，当第一网络设备未收到该第一指示信息，则确定终端设备不支持测量终端侧时延或时延信息中不含有终端侧时延。本申请实施例中不限定指示信息的具体形式。
通信系统中，终端设备可以接入接入网设备，并和接入网设备进行通信。示例性地，一个接入网设备可以管理一个或多个(例如3个或6个等)小区，终端设备可以在该一个或多个小区中的至少一个小区中接入接入网设备，并在该终端设备所在的小区中和接入网设备进行通信。在本申请实施例中，至少一个可以是1个、2个、3个或者更多个，本申请实施例不做限制。
针对如何减少终端侧时延周期上报的性能开销，本申请实施例提供了一种信息传输方法，参阅图9，该信息传输方法的流程包括步骤901至903，具体如下：
901、接入网设备向终端设备发送时延测量消息；
本申请实施例中，接入网设备可能是由于收到核心网设备发送的时延测量信息通知触发通知终端设备进行时延测量；或者，接入网设备是由于收到核心网设备或操作、管理和维护(operation，administration and maintenance，OAM)设备发送的立即最小化路测工作MDT(immediate minimization of drive tests，immediate MDT)的通知才触发通知终端设备进行时延测量；或者是由于其他原因触发通知UE进行时延测量，具体触发条件此处不做限定。
时延测量消息可以为无线资源控制(radio resource control，RRC)重配消息，即接入网设备通过RRC重配消息通知终端设备进行终端侧时延的测量，比如在RRC重配消息中的其他配置(otherconfig)或者测量配置(measConfig)中携带通知终端设备进行时延测量的信息。比如携带对数据无线承载(data radio bearer，DRB)进行时延测量的标识即携带DRB标识(identity，ID)。
可选的，接入网设备可以通知终端设备进行周期性的终端侧时延测量，并周期上报或周期性上报对应的终端侧时延周期性取值，一个周期的时长可以为200毫秒或500毫秒等，一个周期的时长本申请实施例中不做限定。
902、终端设备测量终端侧时延；
终端设备收到时延测量消息后测量终端侧时延，在一种可行的实施方式下，终端设备周期性的测量终端侧时延，一个周期的时长可以为200毫秒或500毫秒等，一个周期的时长本申请实施例中不做限定。
903、终端设备向接入网设备发送终端侧时延。
对于终端侧时延变化不大的场景，可以减少终端侧设备向接入网设备发送终端侧时延的次数，接入网设备根据历史数据得到终端侧时延，以此减少数据传输占用的网络资源。
如在终端设备周期性进行终端侧时延的测量和上报时，若当前需要上报的终端侧时延值，即本周期测量到的终端侧时延值，符合预设的时延范围，预设的时延范围可以由终端设备上次上报的终端侧时延得到，如预设的时延范围为上次上报的终端侧时延的0.9倍到1.1倍或者与上次上报的终端侧时延的差别在1毫秒范围内，即如果当前需要上报的取值与上次上报的终端侧时延值的差别在一个时延范围内，则终端设备可以不上报本次测量结果，否则，终端设备上报测量到的终端侧时延。该时延范围可以由接入网设备通知终端设备(比如在时延测量信息中携带)或者通过事先通过的协议固定该时延范围，终端设备获取时延范围的方式此处不做限定。接入网设备还可以通知终端设备是否需要进行处于该时延范围的判断，即直接上报还是判断与上次上报的值的差别在一个时延范围内。
可选的，对于终端设备第一次向接入网设备发送终端侧时延，终端设备可以将该终端侧时延和一个初始值进行比较，如果当前需要上报的终端侧时延与初始值的差别在一个时延范围内，则终端设备无需上报本次测量结果，否则终端设备上报本次测量结果。该初始值可以由接入网申通知终端设备(比如在时延测量消息中携带)或者通过事先通过的协议固定该初始值，终端设备获取初始值的方式此处不做限定。
可选的，本实施例中终端设备可以在每次上报终端侧时延时，都和初始值进行判断比较，如果当前需要上报的终端侧时延与初始值的差别在一个时延范围内，则终端设备无需上报本次终端侧时延测量结果，否则终端设备上报本次终端侧时延测量结果。
在无线网络中，一个终端设备可以通过多无线的双连接(multi-radio dual connectivity，MR-DC)技术与多个接入网设备通信。MR-DC通信中，与核心网有控制面信令交互的接入网设备称为主节点(master node，MN)，其他接入网设备称为辅节点(secondary node，SN)。MN中包括主小区组(master cell group，MCG)，MCG至少包括一个PCell，还可以包括至少一个辅小区(secondary cell，SCell)，这些小区都称为终端设备的MCG服务小区。SN中包括辅小区组(secondary cell group，SCG)，SCG至少包括一个PSCell，还可以包括至少一个SCell，这些小区都称为终端设备的SCG服务小区。根据无线接入技术的不同，MR-DC包括例如演进的通用陆基无线接入和新无线组成双连接(E-UTRA-NR dual connectivity，EN-DC)、下一代无线接入节点演进的通用陆基无线接入和新无线组成双连接(NG-RAN E-UTRA-NR dual connectivity，NGEN-DC)、新无线和演进的通用陆基无线接入组成双连接(NR-E-UTRA dual connectivity，NE-DC)、新无线和新无线组成的双连接(NR-NR dual connectivity，NR-DC)。主节点和辅节点都可以为终端设备配置immediate MDT测量。对于基于管理的immediate MDT，辅节点可以从OAM设备接收基于管理的immediate MDT的时延测量信息，辅节点测量辅节点和终端设备间进行数据传输的时延。对于管理的MDT而言，接入网设备会从OAM设备接收MDT配置信息，配置信息中包括了跟踪参考(trace reference)、TCE的IP地址、匿名传输的需求。其中跟踪记录会话参考是用于标识一个跟踪会话中的一个跟踪记录会话。匿名传输的需求是指OAM设备或TCE可能需要测量结果对应的终端设备的类型信息(示例性的，终端设备的厂商、终端设备的类型等，比如国际移动设备标识类型分配码(IMEI type allocation code，IMEI-TAC))。例如，对于基于管理的MDT测量而言，OAM或跟踪收集实体TCE根据得到的 终端设备的类型信息结合该终端设备的基于管理的MDT测量结果，分析得到测量结果所涉及的终端设备的类型信息所对应的这类终端设备在该网络下的性能。接入网设备会选择对应的终端设备进行MDT测量(比如根据终端设备是否支持对应测量等)，接入网设备会为选择的终端设备分配一个跟踪记录会话参考(trace recording session reference)。跟踪参考是用于标识一个跟踪会话的，且是全局唯一的。跟踪记录会话参考是用于标识一个跟踪会话中的一个跟踪记录会话。其中，跟踪会话是一个时间段，起点是一个跟踪会话的激活时间，终点是该跟踪会话的去激活时间；跟踪记录是跟踪收集的数据。跟踪记录会话是指在一个跟踪会话中跟踪记录产生的时间间隔。而终端设备的类型只有核心网才能知道，所以对于辅节点配置的MDT测量结果而言，OAM或TCE可能需要知道终端设备的类型信息。本申请还提供了一种针对SN进行的基于管理的MDT测量如何获取终端设备的类型信息的方法，可以包括步骤S1001至S1007。
具体如下：
S1001、SN从OAM获取MDT测量配置信息；
MDT测量配置信息包括了跟踪参考(trace reference)、TCE的IP地址、匿名传输的需求。该MDT测量包括immediate MDT测量。比如如前面所述的终端设备和所述接入网设备间进行数据传输时的时延测量，或者其他的immediate MDT测量，比如让终端设备测量小区的下行信号质量。
S1002、SN为终端设备配置MDT测量；
SN选择终端设备进行MDT测量。当MDT测量为时延测量时，SN向终端设备发送时延测量消息，具体方法同前面图5所示实施例中步骤504所述。当MDT测量为下行信号质量测量时，SN向终端设备发送测量消息，测量消息中携带让终端进行下行信号质量测量的配置信息。
S1003、SN获取终端设备的MDT测量结果；
SN获取终端设备对应的MDT测量结果。当MDT测量为时延测量时，终端设备向SN发送时延测量结果的方法同图5中的步骤505、506。当MDT测量为下行信号质量测量时，终端设备向SN上报下行信号质量测量结果。
S1004、SN向MN发送消息，该消息中携带终端设备进行的MDT测量对应的跟踪标识、TCE的IP地址信息等；
当SN从OAM获取的MDT测量配置信息中指示的匿名传输的需求为需要IMEI-TAC时，该消息中还携带隐私指示(privacy indicator)，隐私指示中携带MDT的类型，比如取值为logged MDT或immediate MDT。其中跟踪标识是由跟踪参考和跟踪记录会话参考构成。
S1005、MN向核心网发送消息，该消息中携带跟踪标识、TCE IP地址信息等。
跟踪标识、TCE信息为MN从SN接收的信息。如果步骤S1005中，SN给MN发送的消息中携带隐私指示，则MN把该隐私指示也一块发送给核心网。
该消息中还携带终端设备当前的PCell的标识，比如PCell的全局小区标识(cell global identification，CGI)。
S1006、核心网发送TCE发送消息，该消息中携带跟踪标识、TCE IP地址信息等。
跟踪标识、TCE信息为核心网从MN接收的信息。如果步骤S1006中，MN给核心网发送的消息中携带隐私指示，则核心网会从数据库中查找对应的用户标识(比如IMEI(SV))，并把IMEI-TAC和跟踪记录会话参考和跟踪参考发送给TCE。对于immediate MDT而言，核心网还把从MN收到的PCell的标识发送给TCE。
S1007、SN向TCE发送MDT测量结果。
SN获取到MDT测量结果之后，把MDT测量结果发送给TCE。同时SN把MN中的PCell的标识发送给TCE。可选的，其中MN的PCell的标识是SN从MN获取的，即MN会把PCell的标识发送给SN。可选的，SN还会把终端设备在SN中的服务小区的标识(比如PSCell的CGI)也发送给TCE。
通过以上方法，SN给TCE发送的测量结果中包括了PCell的标识，同时TCE从核心网中获取了PCell的标识和IMSI-TAC，从而TCE可以知道从SN获取的MDT测量结果对应的终端设备的IMSI-TAC。
