具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的其它实施例，都属于本申请保护的范围。
随着通信技术的发展，用户通过电子设备所能获得的体验越来越丰富。例如，用户通过眼镜或头盔等电子设备可以获得沉浸式体验，这种沉浸式体验能让用户获得身临其境的感受。下面以图1为例，描述一种能提供沉浸式服务的通信系统。
图1为本申请实施例提供的一种通信系统的示意图。如图1所示，在该通信系统中，终端装置110通过无线网络与其它装置通信，该无线网络包括无线接入网(radio access network，RAN)和核心网(CN)，其中RAN用于将终端接入到无线网络，CN用于对终端进行管理并提供与外网通信的网关。该无线网络包括网络设备120，该网络设备120例如为RAN设备。网络设备120与数据库130连接，该数据库130可以位于网络设备120之中，也可以位于网络设备120之外。当数据库130位于网络设备120之外时，网络设备120与数据库130的连接可以是直接连接，也可以是间接连接，所谓间接连接即通过其他设备的连接，例如通过CN设备或网关连接，此时数据库130可以位于服务器，该服务器称为数据库服务器。此外，网络设备120和数据库130的连接可以通过云技术实现，云技术使得区域内的硬件、软件、网络等资源共享，如此，网络设备120可以快速的访问数据库130。
环境100中具有至少一个采集点(又可以称为采样点)，在此，以采集点A，B，C为例，本申请不限制采集点的数量和位置。采集点A，B，C处设置有数据采集装置，例如摄像头，数据采集装置采集到的数据形成数据集，存放在数据库130中。网络设备120获取终端装置110的位置E，并将该位置E通知给数据库服务器，数据库服务器根据位置E，利用数据库中存储的数据，生成位置E的数据(例如，音频和视频数据)传输给网络设备120，网络设备120将位置E的数据传输给终端装置110，终端装置110收到的网络设备120发送的数据，对该数据进行渲染，生成位置E的图像和/ 或音频，通过显示设备140展示给用户。
在该通信系统中，用户的位置，即终端装置110的位置是可以变化的，而对于其位置的变化，希望可以获得实时的数据更新，以为用户提供良好的体验，因此，对数据传输的时延提出了较高的要求。
在本申请的以上或以下实施例中：
终端装置110可以是终端，或位于终端内的装置(例如终端内的芯片)，其中终端又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、或移动终端(mobile terminal，MT)等，是一种向用户提供数据连通性的设备，例如，具有无线连接功能的手持式设备或车载设备等。目前，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、或智慧家庭(smart home)中的无线终端等。
网络设备120是无线网络中的设备，例如将终端接入到无线网络的RAN节点。目前，RAN节点的举例为：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 eNodeB，或home Node B)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wi-Fi)接入点(access point，AP)等。在一种网络结构中，网络设备可以为集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。
请参考图2，其为本申请实施例提供的一种协议架构的示意图。如图2所示，RAN设备和终端装置之间的通信遵循一定的协议层架构。例如控制面协议层架构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层架构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol,SDAP)层，物理层可以称为层1，PDCP层到MAC层可以称为层2。SDAP层可以归为层2，或者可以不归为层2,。
请参考图3，其为本申请实施例提供的一种网络架构的示意图。如图3所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，射频装置包括射频拉远单元(remote radio unit，RRU)，基带装置包括BBU，RRU相对于BBU拉远布置。
图2所示协议层的功能在RAN设备中可以由一个节点实现，或者可以由多个节点实现；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图3所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，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DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图4，相对于图3所示的架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端装置，或者终端装置产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端装置或CU。以下实施例中如果涉及这种信令在DU和终端装置之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端装置，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端装置或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
请继续参考图5，其提供了一种通信流程，通过该通信流程，用户可以获得沉浸式体验。在通信流程中，数据库130存储所有采集点收集的数据，根据终端装置110的位置E，由数据库130所在的服务器(即数据库服务器)生成位置E的数据，并传输给终端装置110，终端装置110对接收到数据进行处理后，通过显示设备140向用户展示。如图5所示，以采集点A，B，C为例进行描述。环境100中的采集点A，B，C处设置有数据采集装置，各采集点的数据采集装置采集数据，并在步骤S510中将采集到的数据提供给服务器，服务器将获得的数据存储于数据库130中。数据采集装置例如包括视频采集装置和/或音频采集装置，其采集的数据例如包括视频数据和/或音频数据。将数据采集装置在采集点A采集到的数据称为数据A，数据采集装置在采集点B采集到的数据称为数据B；数据采集装置在采集点C采集到的数据称为数据C。其中数据A，B，C可以由同一个装置收集后统一发送给服务器，也可以各种数据采集装 置独立发送给服务器。对于由同一个装置收集后统一发送给服务器的场景，该负责统一发送数据的装置可以为采集点A，B，C处设置的数据采集装置中的任一个数据采集装置，也可以为独立设置的数据搜集装置，用于从数据采集装置收集数据，并统一发送给服务器。
以上数据采集过程可以因事件触发而启动，也可以周期性启动，或者可以在一段时间内持续性进行。且数据采集过程启动之后，数据采集可以周期性进行，也可以持续性进行，数据采集的周期可以应实际需要而设定，不做限制。
如此，服务器可以预先收集到采集点(可以理解为多个观测点)的时频和/或音频数据，并存储于数据库中，且该数据库中的数据可以持续性或周期性更新。
终端装置110根据其位置，记为位置E，生成终端装置的位置信息，并在步骤S520中，向网络设备120发送该位置信息。网络设备120根据该位置信息从数据库130获得位置E的数据。如果数据库130位于网络设备120中，则网络设备120直接根据位置E，利用本地数据库存储的数据生成位置E的数据；如果数据库130独立于网络设备120，例如位于服务器中，则网络设备120在步骤S530中向服务器发送终端装置的位置信息。服务器根据终端装置的位置信息，利用存储的数据，生成位置E的数据，并在步骤S540中，将位置E的数据发送给网络设备120。而后在步骤S550中，将位置E的数据发送给终端装置110。终端装置110对接收到的位置E的数据进行渲染，生成视频和/或音频，并在步骤S560中，通过显示设备140展示给用户。
不同位置相对于采集点ABC的视频和/或音频不同，数据库服务器根据位置信息可以确定位置E相对于采集点ABC的位置，以终端装置的位置为参数，可以采集点ABC的数据生成位置E的数据，该位置E的数据即可以体现位置E所能观测到的视频和/或音频。且不同清晰度的图像可以采用不同的算法来生成位置E的数据，清晰度越高，算法越复杂，处理时延越大。
网络设备120与终端装置110之间的传输容量有限，而视频和/或音频(尤其是高清视频)的数据量又很大，所以步骤S540传输的位置E的数据可以是位置E的完整视频和/或音频数据，也可以是完整数据的一部分，即部分数据。相应的，步骤S550中传输的数据可以是完整数据，也可以是部分数据。或者，步骤S540中传输的位置E的数据可以是完整数据，而网络设备120自行决定传输完整数据或部分数据，此时，步骤S550中传输的数据可以是完整数据，也可以是部分数据。当终端装置110接收到部分数据时，可以对接收到的数据进行渲染，以对缺失的部分进行补充，从而向用户显示视频和/或音频。此时，最终用于显示的数据，既包含真实的数据，也包含渲染的数据。渲染是指是根据图像的主干部分，利用算法推测出图像的细节部分以对图像进行补足，从而提升图像画面质量。
通过以上通信流程，用户可以获得沉浸式体验。对于服务器来说，服务器生成位置E的数据时，不知道空口能传输多少数据，所以按最高清晰度生成数据，复杂度较高，相应的处理时延较大，但最终可能只有一部分数据传输到终端装置。对于终端装置来说，从网络设备获取位置E的数据之后，根据数据量确定渲染算法，实施渲染，相应的处理时延较大。
考虑到以上技术问题，在一种实现中，网络设备可以将空口的信息提供给服务器， 从而服务器在生成位置E的数据时，可以知道空口的信息，从而根据该空口的信息优化生成数据的算法，从而加快生成位置E的数据的处理速度，减少处理时延，进而提高用户体验。例如空口的信息包括以下信息中的一个或多个：速率、带宽(或称为频率资源大小)、无线信号质量或天线数量等信息，服务器根据该空口的信息可以确定网络设备和终端装置之间的传输容量，进而生成该传输容量可以容纳的位置E的数据，即传输容量越小，生成清晰度越低的数据，而清晰度越低的数据所需的算法复杂度越低，处理时延越低。且，由于即使生成了最高清晰度的数据，由于网络设备和终端装置之间的传输容量有限，也无法传输给终端装置，因此这种方式，即可以降低处理时延，又不会降低视频和/或音频质量。
在另一种实现中，网络设备可以将空口的信息提供给终端装置，如此终端装置能够预先估计或确定网络设备发送的数据量，如此，可以提前确定处理方式(例如，渲染算法)，准备处理，从而加快处理速度，降低处理时延，提高用户体验。
下面结合附图，进行描述。
请参考图6，其为本申请实施例提供的一种通信方法的示意图。如图6所示，该方法包括如下步骤：
S610：终端装置确定自身的位置，并指示给网络设备；即终端装置向网络设备发送位置信息。相应的，网络设备从终端装置接收该终端装置的位置信息，即从终端装置接收位置信息，该位置信息用于指示终端装置的位置，该终端的位置用E来表示。
可选的，该终端装置的位置例如包括终端装置的坐标。该坐标例如为经纬度，此时终端装置的位置信息用于指示所述经纬度。或者，设置一个基准点，该基准点可以为一个实际设置的采集点或一个虚拟的基准点，终端装置的坐标包括南北水平线、东西水平线、和垂直线相对于该基准点的坐标值，根据这些坐标值，可以确定终端装置在该坐标系中的位置；此时，终端装置的位置信息用于指示终端装置相对于基准点的坐标值。以上坐标线为南北水平线、东西水平线、和垂直线，本申请实施例不做限制，也可以为其它方向的坐标线。
S620：网络设备确定空口状态。
该空口状态是对于终端装置的空口状态，在一种实现中，可以体现网络设备可以向该终端装置传输多少数据，例如时间单元内可以向终端传输多少数据，网络设备和数据库服务器对于时间单元具有相同的理解，此时，该空口状态可以为数据量。单位可以为比特，或字节(byte)等，本申请实施例对单位不做限制。时间单元例如为时隙，正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，子帧或帧，或者可以为预设的时间值，例如0.5ms，1ms，或其它时间等，本申请实施例不做限制。
在另一种实现中，空口状态可以通过空口的速率来体现，即单位时间内传输的数据量，该单位时间可以为以上的时间单元。可见数据量和速率的实现是类似的，区别在于单位不同，且对于数据量，网络设备和数据库服务器对数据量对于时间单元具有相同的理解。
进一步地，可以将速率或数据量按层进行细化，例如划分为第一层的速率和第二层的速率；或者按比例进行划分，例如给出第一层和第二层速率的比例。以字节为例， 第一层的速率为N1字节/单位时间，第二层的速率为N2字节/单位时间；或者，第一层和第二层单位时间内传输的数据量的比例为M1：M2或第一层单位时间内传输的数量占总量的P％或第二层单位时间内传输的数量占总量的Q％，其中N1，N2，P和Q均为非负数，M1和M2为正整数。第一层例如基本层，第二层例如为增强层，其中基础层的数据可以体现图像的基本骨架，可以理解为，终端装置根据基础层的数据能产生图像(该图像的清晰度较低)，增强层的数据包含图像的细节信息，终端装置根据基础层和增强层的数据能产生更高清晰度的图像。这里仅以两层划分为例，本申请实施例不做限制，可以将终端装置的数据划分为多于两层的数据，其包括基本层和多于一个增强层，每个层级的增强层对应的图像的清晰度不同。多层之间的优先级不同，但空口状态不足以容纳所有层的数据时，优先传输优先级高的层级的数据。在一种实现中，基本层的优先级最高，有多个增强层时，增强层对应的图像清晰度越高，优先级月低。
在另一种实现中，该空口状态可体现为空口的频率资源大小，该频率资源大小例如是网络设备可以分配给终端装置的最大频率资源，或者是网络设备使用的当前载波的带宽大小或当前部分带宽(bandwidth part，BP)大小。频率资源越大，网络设备可以利用的资源越多，因此，网络设备和终端之间传输的容量越大。
在又一种实现中，该空口状态可以体现为无线信号质量(或者称为信道的质量)，例如，参考信号接收功率(reference signal received power，RSRP)或参考信号接收质量(reference signal received quality，RSRQ)。无线信号质量越好，网络设备可以传输的数据越多，因此，网络设备和终端之间传输的容量越大。
在又一种实现中，该空口状态可以体现为天线数量，天线数量越大，网络设备的传输能力越强，因此，网络设备和终端之间传输的容量越大。
因此，以上空口状态例如包括包括以下信息中的一个或多个：速率、带宽(或称为频率资源大小)、无线信号质量或天线数量等信息。其中，速率又可以称为传输速率。
一种实现中，网络设备可以根据终端装置的业务优先级、或服务质量(quality of service，QoS)等信息，确定空口状态。例如根据终端装置的业务优先级确定速率。
S630：网络设备向数据库服务器提供空口状态，即网络设备向数据库服务器发送指示空口状态的信息(以下称为信息I1)，其中数据库服务器即数据库所在的服务器。
以上步骤S610可以在该步骤S630之前进行，也可以在步骤S630之后进行。也就是说，网络设备可以在向数据服务器发送信息I1之前，获取终端装置的位置信息，此时，网络设备可以将信息I1和位置信息一起发送给数据库服务器，从而节省信令流程。可选的，也可以将信息I1和位置信息独立发送给数据库服务器。网络设备在向数据服务器提供空口状态之后，获取终端装置的位置信息时，可以在发送信息I1之后，再向数据库服务器发送位置信息。
如果之前空口的速率或数据量按层进行了细化，此时，网络设备可以向数据库服务器通知细化的速率或数据量。例如信息I1包括多个层的速率信息或数据量信息，例如第一层的速率信息和第二层的速率信息；或者包括多个层之间的速率比例，例如第一层和第二层的速率比例。或者，信息I1可以包括多个层的数据量信息，例如第一层 的数据量信息和第二层的数据量信息；或者包括多个层之间的数据量比例，例如第一层和第二层的数据量比例。
相应的，数据库服务器接收信息I1和终端装置的位置信息(即位置E的信息)，并根据接收到的信息执行以下操作：
S640：数据库服务器根据空口状态和终端装置的位置生成该位置的数据(以下可以称为数据D1)，即位置E的数据。
在一种实现中，数据库服务器根据终端装置的位置生成该位置的预设清晰度数据，并且把这些数据划分为若干层，具体划分同以上实施例，不再赘述；而后，根据空口状态，确定传输哪层或哪些层的数据。其中数据库服务器预先配置默认的数据生成算法和/或参数，该数据生成算法和/或参数利用从采集点搜集到的数据，生成终端所在位置的预设清晰度的数据，通常该默认的数据生成算法和/或参数生成高清晰度的数据，而后由于空口状态不允许这么多数据的传输，因此，可以传输部分层的数据给网络设备。在此，将传输给网络设备的数据理解为数据D1，即位置E的数据。也就是说，数据D1是数据库服务器生成的数据的部分或全部。
在另一种实现中，数据库服务器根据空口状态，确定数据生成算法和/或参数，其中不同的数据生成算法和/或参数对应生成不同的清晰度的数据。数据库服务器根据终端装置的位置和选择的数据生成算法和/或参数生成数据D1，即位置E的数据，并将数据D1发送给网络设备。
数据库服务器可以预设有多种数据生成算法，每个数据生成算法对应不同的清晰度，适用于不同的空口状态。或者，数据库服务器可以预设有一种数据生成算法，不同的参数对应不同的清晰度，适用于不同的空口状态。或者，数据库服务器既预设有多种数据生成算法，又有不同的参数适用于不同的数据生成算法，以生成不同清晰度的数据；或者每种算法下利用不同的参数进一步生成更细粒度的清晰度的数据。
S650：数据库服务器向网络设备发送数据D1，相应的，网络设备从数据库服务器获取数据D1，即位置E的数据。
S660：网络设备向终端装置发送数据D1，即位置E的数据。
另一方面，网络设备还可以向终端装置提供以上空口状态，以便终端装置根据空口状态确定对数据的处理方式，从而提前准备好对接收到的数据的处理，从而加快处理速度，降低处理时延，提高用户体验。此时，以上方法还包括：
S670：网络设备向终端装置提供空口状态，即网络设备向终端装置发送指示空口状态的信息。
关于空口状态的描述同以上步骤S630中的描述，在此不再赘述。其中对于空口状态为数据量时，网络设备和终端装置对于时间单元具有相同的理解。
如果网络设备已经存储了即将发送给终端装置的数据或者可以根据空口状态预判即将发送给终端装置的数据量，则网络设备可以向终端装置发送数据量指示信息，该数据量指示信息用于指示，网络设备即将向终端装置传输的数据量或网络设备存储的数据量。
网络设备即将向终端装置传输的数据量可以理解为空口状态为数据量时的一种情况。网络设备存储的数据量可以理解为空口状态为数据量时的一种情况，也可以单独 由网络设备根据其存储的数据量来确定。
因此，以上步骤S670中，网络设备可以向终端装置发送指示空口状态的信息，或者，可以向终端装置发送指示网络设备存储的数据量的信息。即，网络设备向终端发送信息I2，其中信息I2用于指示空口状态或用于指示网络设备存储的数据量，即网络设备缓存的状态。
当信息I2指示数据量时，其可以直接指示数据量，也可以以一种占比的方式指示，例如预设清晰度的数据对应的数据量为100％，当前数据量占预设清晰度的数据对应的数据量为S％，则信息I2用于指示S％。该预设预设清晰度例如为最高清晰度。
相应的，终端装置接收信息I2，并执行以下操作：
S680：终端装置根据信息I2，处理接收到的数据D1，即位置E的数据。
终端装置可以在接收到信息I2之后，才收到位置E的数据，此时，终端装置根据信息I2，确定处理数据的方式，例如渲染算法和/或参数，如此，提前做好了处理数据的准备，当收到数据D1时，对数据D1进行处理，并将处理后的数据通过显示设备进行显示。终端装置可以在接收到信息I2之前，就已经收到位置E的数据，此时，终端装置根据信息I2或根据收到的数据，确定处理数据的方式，并对之前存储的位置E的数据进行处理，等到终端装置后续再收到新的数据之后，更新处理的数据，并将处理后的数据通过显示设备进行显示。
终端装置可以预设有多种数据处理算法(例如，渲染算法)，每个数据处理算法对应不同的清晰度，适用于不同的空口状态或数据量。或者，终端装置可以预设有一种数据处理算法(例如，渲染算法)，不同的参数对应不同的清晰度，适用于不同的空口状态或数据量。或者，终端装置既预设有多种数据处理算法，又有不同的参数适用于不同的数据处理算法，以处理不同清晰度的数据；或者每种算法下利用不同的参数进一步处理更细粒度的清晰度的数据。
可选的，在以上步骤S610中，终端装置还可以将视角指示给网络设备，即以上方法还可以包括：终端装置向网络设备发送视角信息；相应的，网络设备从终端装置接收该终端装置的视角信息，即从终端装置接收视角信息，该视角信息用于指示终端装置的视角。而后续网络设备进一步将该视角信息和位置信息提供给数据库服务器，以便数据库服务器生成对应位置和视角的数据，如此，可以数据库服务器可以将生成的数据限定到某个视角范围内，因此进一步减少生成的数据量，降低处理时延，进一步提高用户体验。以下其它实施例中，终端装置除了向网络设备或数据库服务器提供位置信息，还可以提供视角信息，在以下实施例中不再赘述。
在以上步骤S670中，网络设备可以采用RRC消息，PDCP控制协议数据单元(protocol data unit，PDU)或MAC控制元素(MAC control element，MAC CE)向终端装置发送信息I2。当该信息通过MAC CE发送时，该MAC CE所在的MAP子PDU的子头中包括逻辑信道标识(logical channel ID，LCID)，该LCID的取一预留值，并将该预留值赋予新的含义，即指示MAC CE用于指示空口状态或网络设备存储的数据量。也就是说，MAC CE位于MAC子PDU中，该MAC子PDU包括MAC子头和MAC CE，MAC子头包括LCID，LCID取预设值，该预设值用于指示MAC CE包括以上信息I2。
请参考图7，其为本申请实施例提供的几种MAC子PDU的格式示意图。如图7所示，该MAC子PDU的MAC子头仅示出了相关域，例如MAC子头中的LCID域，该MAC子头还可以包括其它域，本申请实施例不做限制。在格式一中：MAC CE仅包括信息I2，其指示了空口状态或网络设备存储的数据量。例如信息I2指示了N(N为大于或等于1的正整数)个帧所对应的数据量是5000字节。在格式二中：MAC CE除了包括信息I2，还包括时间信息T，用于指示数据在时间信息所指示的时间内传输或到达，其中信息I2指示了该数据的传输速率或数据量。因此，该MAC CE表示在时间T内，网络设备会向终端装置发送数据，同样以信息I2指示了N(N为大于或等于1的正整数)个帧所对应的数据量是5000字节为例，则该MAC CE指示了时间T内，网络设备会向终端装置传输5000字节的数据量。对于格式一，网络设备也可以向终端装置指示时间T，与格式二的区别在于，网络设备通过RRC消息预先向终端装置配置时间T。在格式三中，终端装置的数据被划分为至少一个层的数据，信息I2包括至少一个层信息和至少一个信元，每个信元对应一个层信息，用于指示该层信息所指示的层的状态或数据量，例如，该MAC CE包括第一层和第二层的信息，信元一用于指示N个帧内第一层的数据量为5000字节，信元二用于指示N个帧内第二层的数据量为3000字节，其中第一层为基础层，第二层为增强层。此外，图中仅以两层为例，在其它实现方式中，可以有一层或多于两层。可选的，当采用格式三时，也可以在MAC CE中增加指示时间T的信息。此外，网络设备可以预先将各层之间的速率比例或数据量比例通知给终端装置，而后仅在MAC CE中指示一个层的速率或数据量，终端装置即可以知道其他层的速率或数据量。同样以两层为例，假设第一层和第二层的数据量比例为1：3，MAC CE指示第一层的数据量为1000字节，则终端装置可以确定第二层的数据量为3000字节或者确定总的数据量为4000字节。这里仅以数据量为例，关于其它空口状态与之类似，不再赘述。
网络设备可以周期性向终端装置发送信息I2。或者，网络设备可以在其存储的数量超过阈值(包括大于或等于阈值)时，向终端装置发送信息I2，如此，可以减少信令交互，进一步提升处理速度，降低处理时延。
网络设备可以分别向多个终端装置发送信息I2，如果网络设备要向多个终端装置发送以上数据，则可以以广播或组播的方式将信息I2发送给多个终端装置；或者，可以单独向每个终端装置发送信息I2。在一种实现中，可以将多个终端装置划分为一个组，通过一个公共的消息，将信息I2发送给组内的所有终端装置。可以为该组的终端装置分配相同的组标识，用于接收该信息I2。
在以上的实施例中，数据D1是通过数据库服务器根据终端的位置和空口状态确定的。在另一种实现中，网络设备可以不向数据库服务器提供空口状态，而是数据库服务器根据终端的位置生成位置E的数据(记为数据D2)，发送给网络设备，而后由网络设备根据空口状态，利用数据D2生成数据D1。例如，将数据D2分成若干层，根据空口状态，仅传输部分层的数据，该部分层的数据即为D1。再如，将数据D2压缩或将数据D2转换为更低清晰度的数据D1，本申请实施例不做限制。
以上步骤S630和S670可以仅执行其中一个步骤，也可以都执行，也就是说网络设备可以向终端装置提供空口状态或存储的数据量，和/或，向数据库服务器提供空口 状态；从而使得终端装置可以根据空口状态或根据网络设备存储的数据量提前准备数据处理方式，提高数据处理效率。此外，在图5所示的方法中，数据库服务器生成的位置E的数据为高清视频和/或音频数据，由于空口传输容量受限，不能将生成的数据全部传输到终端装置，而本申请实施例中，将空口状态通知数据库服务器，数据库服务器根据空口状态调整生成位置E的数据的算法，生成的数据量符合空口传输的能力，或者根据空口状态仅传输部分生成的数据给网络设备，因此，减少了数据生成的复杂度或有效利用了空口资源，提升了数据处理效率，进而提升了用户体验。
在以上实施例中，数据库服务器根据终端装置的位置E，利用存储的数据(例如采样点ABC)的数据，生成位置E的数据，通过网络设备发送给终端装置。在本申请的另一实施例中，将“生成位置E的数据”这一功能放到网络设备实现，数据库服务器预先将参考点(全部或部分采样点)采集到的数据传输到网络设备，由网络设备根据终端的位置生成终端所在位置的数据。该终端所在位置的数据的生成可以采用以上实施例中的方式生成，即根据空口状态生成；或者，可以不考虑空口状态，根据终端装置的位置生成，而后传输部分生成的数据。也就是说，本实施例可以与以上实施例结合，区别在于，以上实施例中根据空口状态生成位置E的数据是由数据库服务器执行的，而本实施例中，由网络设备执行，具体可以参照以上实施例，在此不再赘述。
进一步的，如果网络设备还需要更多参考点的数据，或者还需要当前参考点的进一步的数据时，可以向数据库服务器发送请求消息，以获得更多的参考点的数据，或获得当前参考点更多的参考数据，以生成进一步的终端装置所在位置的数据。
终端装置处理(例如，渲染)接收到的数据，并通过显示设备向用户显示视频和/或音频。该终端装置的处理方式可以采用以上实施例的方式，即根据空口状态或网络设备存储的数据量，提前确定处理方式，而利用确定的处理方式处理接收到的数据。或者，可以在接收到数据时，再确定处理方式，本实施例不做限制。此外，终端装置收到网络设备进一步生成的终端装置所在位置的数据时，可以更新处理结果。
下面结合附图进行描述。
请参考图8，其为本申请实施例提供的另一种通信方法的示意图。如图8所示，该方法包括如下步骤：
S810：数据库服务器将第一参考位置的数据发送给网络设备。第一参考位置包括至少一个参考点，在此以采集点A,B,C为参考点为例。
数据库服务器中存储有各个采集点采集的数据，其中采集点A,B,C为参考点，数据库服务器中存储有参考点A,B,C点的全部数据。而数据库服务器可以将A,B,C点的全部数据发送给网络设备，或者，可以将A,B,C点的部分数据发送给网络设备。
相应的，网络设备接收第一参考位置的数据，即A,B,C点的数据(数据库中存储的A,B,C点的全部或部分数据)，并保存接收到的A,B,C点的数据。
S820：网络设备获取终端装置的位置信息，即位置E的信息。
S830：网络设备根据终端装置的位置，利用第一参考位置的数据，生成下行数据，也就是发送给终端装置的数据，即位置E的数据。
关于位置E的数据的生成方式同以上描述，在此不再赘述。
S840：网络设备将下行数据(即位置E的数据)发送给终端装置。
相应的，终端装置接收位置E的数据，并执行以下操作：
S850：终端装置对下行数据(即位置E的数据)进行处理。
关于位置E的数据的处理方式同以上描述，在此不再赘述。
可选的，网络设备确定当前精度不足，还需要更多参考点的数据，或者还需要当前参考点的进一步的数据时，可以向数据库服务器发送请求消息，以获得更多的参考位置的数据，或获得当前参考位置更多的参考数据，以生成进一步的位置E的数据，即执行以下操作：
S860：网络设备向数据库服务器发送请求消息，该请求消息用于请求第二参考位置的数据。
第二参考位置可以与第一参考位置不同，或者可以与第一参考位置相同。此外，第二参考位置可以包括第一参考位置，或者，不包括第一参考位置。
例如，用于请求相同参考点A,B,C的进一步的数据，或者用于请求其它参考点D的数据；或者用于请求当前参考点A,B,C和其它参考点D的数据。其它参考点以参考点D为例，本申请实施例不做限制，还可以包括更多的参考点，例如F和H等。
可选的，可以由网络设备根据终端装置的位置信息确定第二参考位置；或者可以将终端装置的位置信息发送给数据库服务器，由数据库服务器确定第二参考位置，此时以上请求消息可以包括终端装置的位置信息。
在此，以数据库服务器确定第二参考位置为例，且以第二参考位置为参考点A,B,C和D为例，如图8所示，以上方法还包括：
S870：数据库服务器获取第二参考位置的数据。
例如，数据库服务器根据终端装置的位置确定第二参考位置，例如参考点A,B,C和D，并获取第二参考位置的数据。
S880：数据库服务器将第二参考位置的数据发送给网络设备，例如发送参考点A,B,C和D的数据。
相应的，网络设备接收第二参考位置的数据，并执行：
S890：网络设备根据终端装置的位置，利用第二参考位置的数据，进一步生成下行数据，即位置E的数据。
关于位置E的数据的生成方式同以上描述，在此不再赘述。
S800：网络设备将进一步生成的下行数据(即位置E的数据)发送给终端装置。
终端装置重复以上步骤S850，对进一步接收到的下行数据进行处理，或者合并步骤S840和S800中的下行数据，对合并后的数据进行处理。
在以上步骤S810中，数据库服务器将第一参考位置的数据发送给网络服务器，关于第一参考位置的确定，可以通过不同的方式实现，以下结合附图提供几种实现方式的示例。
请参考图9，其为本申请实施例提供的第一参考位置确定方法的示意图：
第一种实现方式(如图9中的方式A1)：网络设备根据终端装置以前上报的位置信息(可以称为历史位置信息)，确定终端装置可能的位置区间，并向数据库服务器指示终端装置可能的位置区间。该位置区间例如通过三维坐标值和半径值体现，表示 终端装置可能位于的一个虚拟的球体范围，该虚拟球体的圆心由三维坐标值确定，半径由网络设备预测。此时，以上方法还包括：网络设备向数据库服务器上报位置区间的信息，所述位置区间的信息用于指示终端装置的位置区间，数据服务器根据该位置区间的信息，确定第一参考位置。以上位置区间的信息包括终端的中心位置坐标的信息和位置区间半径的信息。此外，网络设备还可以向数据库服务器发送聚焦角度的信息。聚焦角度用于指示聚焦的深度，例如近景或远景。以上实施例中的视角信息用于指示用户视角范围，而聚焦角度用于指示聚焦的深度，假设用户视角不变，但是关注的目标发生了变化，比如看风景，一会儿看近景，一会儿看远景。
第二种实现方式(如图9中的方式A2)：终端装置的位置区间的信息由终端装置提供给网络设备，由网络设备透传或解析后传输给数据库服务器，位置区间的信息同第一种实现方式，不再赘述。类似的，终端装置还可以向数据库服务器提供聚焦角度的信息。
第三种实现方式(如图9中的方式A3)：终端装置的位置区间的信息由显示设备提供给网络设备，由终端装置和网络设备透传或解析后传输给数据库服务器，或者由显示设备直接传输给网络设备，由网络设备透传或解析后传输给数据库服务器，位置区间的信息同第一种实现方式，不再赘述。类似的，显示设备还可以向数据库服务器提供聚焦角度的信息。
以上实现方式中，由数据库服务器确定第一参考位置，此外，也可以由网络设备、终端装置或显示设备确定第一参考位置，并向数据库服务器请求第一参考位置的数据。继续参考图9：
第四种实现方式(如图9中的方式B1)：网络设备确定第一参考位置，即要向数据库服务器请求哪些参考点的数据，并向数据库服务器请求第一参考位置的数据。此时以上方法还包括：网络设备确定第一参考位置，向数据库服务器请求第一参考位置的数据。图中，以第一参考位置为参考点A,B,C,D为例。向数据库服务器请求第一参考位置的数据可以通过向数据库服务器发送第一参考位置的信息，例如A,B,C,D的信息。可以将所有采集点进行索引，第一参考位置的信息可以包括参考点A,B,C,D的索引。类似的，网络设备还可以向数据库服务器提供聚焦角度的信息。
第五种实现方式(如图9中的方式B2)：与第四种实现方式类似，区别在于由终端装置确定第一参考位置，并通过网络设备透传第一参考位置的信息给数据库服务器。类似的，终端装置还可以向数据库服务器提供聚焦角度的信息。
第六种实现方式(如图9中的方式B3)：与第四种实现方式类似，区别在于由显示设备确定第一参考位置，并通过网络设备透传第一参考位置的信息给数据库服务器；或通过终端装置和网络设备透传第一参考位置的信息给数据库服务器。类似的，显示设备还可以向数据库服务器提供聚焦角度的信息。
通过以上实现方式中的任一种，数据库服务器可以预先向网络设备提供第一参考位置的数据，此外，数据服务器还可以提供额外的数据给网络设备，例如其它采集点的数据或其它聚焦角度的数据等，本申请实施例不做限制。
图8中S810之后的部分，对实时性要求比较高，因此网络设备存储了第一参考位置的数据之后，如果收到终端装置的位置信息，则生成终端所在位置的数据(即位置 E的数据)，并发送给终端装置，以便终端装置开始渲染流程。如果网络设备认为存储的数据不足以生成终端所在位置的时频和/或音频数据，则可以向数据库服务器进一步请求第二参考位置的数据。终端装置一边执行渲染流程，一边等待网络设备进一步发送的终端所在位置的数据(即位置E的数据)，当接收到网络设备进一步发送的终端所在位置的数据时，完成渲染，通过显示设备向用户显示。
以上过程中，网络设备在存储的数据不足以生成终端所在位置的时频和/或音频数据时，仍然先生成并传输一部分数据，如此，可以让终端装置先根据这部分数据做好渲染准备，等到进一步的数据到达时，可以更加快速的完成渲染处理，提高数据处理效率。
在另一种情形中，网络设备存储的数据足以生成终端所在位置的时频和/或音频数据时，但当前空口状态不足以在短时间内传输这么多数据，如此，可以与以上实施例结合，采用以上实施例描述任一种实现方式来生成位置E的数据。例如，将生成的数据按照优先级分层，或者生成不同优先级的多层数据，而后根据空口状态，确定传输哪个或哪些层的数据。优先级越高的层，该层的数据越优先被传输。再如，根据空口状态和网络设备存储的数据，确定生成数据的量或方式，例如，数据的传输速率越高，生成的数据越多，反之，生成的数据越少。此外，在传输数据之前，可以将空口状态或存储的数据量通知给终端装置，以便终端装置提前做好数据处理准备，具体参考以上实施例，在此不再赘述。
以上实施例中，数据服务器向网络设备提供的数据，和网络设备提供的终端装置的数据，内容不同，数据量相差也很大。在现有技术中，由核心网统计终端装置消耗了多少流量，并计费，如此，该计费方式与实际空口消耗不一致。因此，在本申请实施例中，网络设备向终端装置传输数据后，可以向核心网的计费装置上报空口传输的数据量，该计费装置根据收到网络设备上报的数据量后，统计终端装置在空口传输的数据量，并计费，如此，计费更加合理。
图中为了简化，网络设备和数据服务器之间、数据库服务器和数据采集装置之间的连接都通过直线显示，但其间连接可能经过多个路由器、网关等。例如，网络设备和数据库服务器之间可能通过核心网设备连接，也可能通过其它网元连接，本申请实施例不做限制。
在以上实施例中，数据库服务器或网络设备根据终端装置的位置E生成位置E的数据。在本申请的另一实施例中，将“生成位置E的数据”这一功能放到终端装置实现，其与图8所示的实施例的区别在于，第一参考位置的数据由网络设备进一步发送到终端装置，由终端装置根据第一参考位置的数据生成位置E的数据。至于进一步请求第二参考位置的数据可以由网络设备发起，也可以由终端装置发起。
下面结合图10，进行描述：
请参考图10，其为本申请实施例提供的另一种通信方法的示意图。如图10所示，该方法包括如下步骤：
S101：数据库服务器将第一参考位置的第一数据发送给网络设备。第一参考位置包括至少一个参考点，在此以采集点A,B,C为参考点为例。
相应的，网络设备接收第一参考位置的第一数据。数据库服务器发送给网络设备 的第一参考位置的第一数据可以是服务器中存储的第一参考位置的全部数据或者可以是服务器中存储的第一参考位置的部分数据
以第一参考位置包括参考点A,B,C为例，数据库服务器中存储参考点A,B,C的数据，数据库服务器可以将参考点A,B,C的数据全部发送给网络设备，或者，可以部分发送给网络设备。
S102：网络设备将第一参考位置的第二数据发送给终端装置，其中第二数据包括第一数据的全部或部分。
网络设备可以将接收到的全部或部分第一参考位置的第一数据发送给终端装置。例如，当空口状态不允许进行全部发送时，网络设备将部分第一参考位置的第一数据发送给终端装置。
相应的，终端装置从网络设备接收第一参考位置的第二数据，并存储第二数据。
S103：终端装置根据该终端装置的位置，利用第一参考位置的第二数据，生成该终端装置所在位置的数据，即位置E的数据。
S104：终端装置进一步对位置E的数据进行处理，并提供给显示设备，向用户显示。
在以上过程中，数据库服务器可以将存储的第一参考位置的全部或部分数据传输给网络设备，具体传输的量可以根据数据库服务器与网络设备之间的传输通道的能力来确定。网络设备可以将接收到的第一参考位置的第一数据的全部或部分数据传输给终端装置，具体传输的量可以根据空口状态确定。
终端装置生成位置E的数据时，如果认为当前存储的第一参考位置的第二数据的信息太少，不足以达到要求的精度，可以向网络设备请求更多的信息，例如请求第二参考位置的信息，该第二参考位置可以与第一参考位置相同，或者，可以与第一参考位置相同。此外，第二参考位置可以包括第一参考位置，还可以包括第一参考位置以外的参考点。
此时，以上方法还包括：
终端装置向网络设备发送第一请求消息，所述第一请求消息用于请求第二参考位置的数据。
在一种实现方式中(如图中方式一)：终端装置根据其位置确定第二参考位置，并在第一请求消息中指示第二参考位置。即第一请求消息中包括指示第二参考位置的信息(S1051)。网络设备根据指示第二参考位置的信息，确定第二参考位置，并将存储的第二参考位置的数据发送给终端装置(S1052)。如果在以上步骤S101中，数据库服务器除了提供第一参考位置的数据，还提供了第二参考位置的数据，则网络设备可以将存储的第二参考位置的数据全部或部分发送给终端装置。如果网络设备没有存储第二参考位置的数据或者存储的第二参考位置的数据不足，网络设备可以进一步向数据库服务器请求第二参考位置的数据。例如网络设备将第二参考位置指示给数据库服务器，以便数据库服务器根据第二参考位置向网络设备提供其存储的全部或部分第二参考位置的数据。再如，网络设备确定其存储有第二参考位置的部分参考点的数据，向数据库服务器请求其余参考点的数据，以第二参考位置包括参考点A,B,C,D为例，假设网络设备存储有参考点A,B,C的数据，则网络设备向数据库服务器请求参考点D 的数据，数据库服务器将存储的参考点D的数据全部或部分发送给网络设备。
在另一种实现方式中(如图中方式二)，终端装置将其位置信息发送给网络设备(S1061)，网络设备根据终端装置的位置信息，确定第二参考位置(S1062)，并将存储的第二参考位置的数据发送给终端装置(S1063)。如果在以上步骤S910中，数据库服务器除了提供第一参考位置的数据，还提供了第二参考位置的数据，则网络设备可以将存储的第二参考位置的数据全部或部分发送给终端装置。如果网络设备没有存储第二参考位置的数据或者存储的第二参考位置的数据不足，网络设备可以进一步向数据库服务器请求第二参考位置的数据。请求方式可以有多种：例如网络设备将第二参考位置指示给数据库服务器，以便数据库服务器根据第二参考位置向网络设备提供其存储的全部或部分第二参考位置的数据。再如，网络设备将终端装置的位置信息发送给数据库服务器，以便数据库服务器根据该终端装置的位置信息，确定第二参考位置，并向网络设备提供其存储的全部或部分第二参考位置的数据。再如，网络设备确定其存储有第二参考位置的部分参考点的数据，向数据库服务器请求其余参考点的数据，以第二参考位置包括参考点A,B,C,D为例，假设网络设备存储有参考点A,B,C的数据，则网络设备向数据库服务器请求参考点D的数据，数据库服务器将存储的参考点D的数据全部或部分发送给网络设备。
在又一种实现方式中(如图中方式三)，终端装置将其位置信息发送给网络设备(S1071)，网络设备将终端装置的位置信息发送给数据库服务器(S1072)，其中网络设备可以透传终端装置的位置信息，此时网络设备不知道终端装置的位置；或者可以解析后将该位置信息传输给数据服务器，此时网络设备可以知道终端装置的位置。数据库服务器根据终端装置的位置信息，确定第二参考位置(S1073)，并根据第二参考位置向网络设备提供其存储的全部或部分第二参考位置的数据(S1074)。
其中，终端装置的位置信息同以上实施例，在此不再赘述。
以上方式可以结合使用，例如后种方式结合时，终端装置将其位置信息提供给网络设备，网络设备进而提供给数据库服务器，这样网络设备和数据库服务器都可以做成判断，不断补充满足精度要求的参考位置的数据，提高用户体验和数据处理效率。例如，网络设备根据终端装置的位置信息利用存储的数据生成终端装置所在位置的一部分数据，提供给终端装置，终端装置可以先对这部分数据进行处理；此外，数据库服务器根据终端装置的位置信息利用存储的数据生成终端装置所在位置的另一部分数据，提供给终端装置，终端装置可以进一步对接收到的数据进行更新，进一步处理后，提供给显示设备，显示给用户。
在以上实施例中，网络设备根据空口状态，确定向终端装置传输的数据，但并没有考虑到终端装置自身的情况，比如，终端装置过热或低电量等。本申请实施例考虑到这种情况终端装置的处理能下降，则终端装置向网络设备上报其状态信息，在不影响用户体验的情况下，网络设备根据该状态信息调整传输给终端装置的数据量。
下面结合附图进行描述，请参考图11，其为本申请实施例提供的又一种通信方法的示意图。如图11所示，该方法包括如下步骤：
S111：终端装置向网络设备发送状态指示信息，该状态指示信息用于指示终端装置的状态。相应的，网络设备接收该状态指示信息。
终端装置根据自身的状态向网络设备发送状态指示信息，终端装置的状态包括以下状态的一种或多种：电量、处理器的占用率、内存的占用率，等热量等。其中热量为热量传感器测得的热量。
以电量为例，当终端装置的电量低于或等于预设值时，终端装置向网络设备发送低电量指示。以处理器的占用率或内存的占用率为例，当终端装置的处理器的占用率或内存的占用率高于或等于预设值时，终端装置向网络设备发送高占用率指示。以热量为例，当终端装置的热量高于或等于预设值时，终端装置向网络设备发送高热量指示。
可选的，终端装置可以向网络设备指示其建议的速率，即终端装置除了状态指示信息，还向网络设备发送速率指示信息，该速率指示信息用于指示终端装置建议的数据传输速率或建议的数据传输速率下降的值。如此，网络设备基于接收到的速率指示信息调整向终端装置传输数据的速率。状态指示信息和速率指示信息可以同时发送，例如承载于同一消息中，或者，终端装置可以仅发送速率指示信息，网络设备根据该速率指示信息直接调整向终端装置传输数据的速率。
为了减少空口资源的占用，可以预先设定几个备选的速率，每个速率由一个索引值指示。则以上速率指示信息可以为一个速率的索引值。
S112：网络设备根据状态指示信息，调整向终端装置传输数据的速率。
例如，当网络设备接收到状态指示信息时，网络设备降低向终端装置传输数据的速率。在一种实现中，可以设置速率下降的步进值，当收到状态指示时，将速率下行一个步进值；当再次收到状态指示信息，再下降一个步进值，依次类推。在另一种实现中，可以设置一个预设值，当收到状态指示信息时，可以将速率下降到预设值。再有一种实现中，网络设备基于接收到的速率指示信息调整向终端装置传输数据的速率。
进一步的，网络设备可以将调整后的速率通知数据库服务器和/或终端装置，同以上图6所示实施例的描述，相当于将调整后的空口状态通知数据库服务器和/或终端装置，如此，数据库服务器可以根据调整后的速率，调整生成终端装置所在位置的数据的算法，降低生成的数据量，以适配降低后的速率；终端装置可以根据调整后的速率，调整数据处理方式，例如对渲染算法进行调整，对接收到的数据进行深度渲染，以降低对用户的影响。
此时，以上方法还包括：
S113：网络设备向数据库服务器发送指示调整后的速率的信息。相应的，数据库服务器接收指示调整后的速率的信息。
S114：数据库服务器根据调整后的速率，生成终端装置的数据。并将终端装置的数据发送给网络设备，以通过网络设备发送给终端装置。
S115：网络设备向终端装置发送指示调整后的速率的信息。
当终端装置网络设备设备建议调整后的速率时，网络设备可以不执行该步骤S103，终端装置即可以自己根据建议的速率调整数据处理方式。
S116：终端装置根据调整后的速率，处理终端装置接收到的数据。
以上步骤S116中处理的数据可以是步骤S114中生成的数据，或者，可以是步骤S114中生成的数据的部分数据，或者，可以是步骤S114之前或之后，终端装置接收 的数据，本申请实施例不做限制。
在以上实施例已经描述，终端装置所在位置的数据可以由数据库服务器生成，或者可以由网络设备生成，当由网络设备生成时，本申请实施例提供的又一种通信方法如图12所示，该方法包括如下步骤：
S121：终端装置向网络设备发送状态指示信息，该状态指示信息用于指示终端装置的状态。相应的，网络设备接收该状态指示信息。
步骤S121的实现同以上步骤S111，且终端装置还可以发送速率指示信息，或者状态指示信息可以由速率指示信息替代。
S122：网络设备根据状态指示信息，调整向终端装置传输数据的速率。
S123：网络设备根据调整后的速率，生成终端装置的数据。
此外，网络设备也可以执行以上步骤S113和S115之一或全部，其后续终端装置可以执行步骤S116。
可选的，以上步骤S113可以替换为网络设备向数据库服务器发送参考帧需求信息。参考帧的需求信息用于指示数据库服务器发送参考帧的周期，如此数据库服务器可以根据参考帧的需求信息周期性发送参考帧。参考帧是不需要参照其它帧，接收方就能独立解码的帧。如果空口状态比较差，网络设备可以要求更频繁地传输参考帧。网络设备也可以一次性请求数据库服务器发送参考帧，或者可以请求一次，发一次。
数据库服务器根据接收到的指示调整后的速率的信息或参考帧需求信息，执行以下操作：
S123：数据库服务器根据指示调整后的速率的信息或参考帧需求信息，减小向网络设备发送的数据量，或减少向网络设备发送的参考帧的数据量，即向网络设备发送调整后的数据量。
类似的，以上步骤S116中处理的数据可以是步骤S123中生成的数据，或者，可以是步骤S123之前或之后，终端装置接收的数据，本申请实施例不做限制。
在以上实施例已经描述，终端装置所在位置的数据可以由终端装置生成，当由终端装置生成时，本申请实施例提供的又一种通信方法如图13所示，该方法包括如下步骤：
S131：终端装置向网络设备发送状态指示信息，该状态指示信息用于指示终端装置的状态。相应的，网络设备接收该状态指示信息。
步骤S131的实现同以上S111，且终端装置还可以发送速率指示信息，或者状态指示信息可以由速率指示信息替代。
S132：网络设备根据调整后的速率，调整向终端装置传输数据的速率。
与图11所示实施例不同的是，向终端装置传输的数据不是终端装置所在位置的数据，而是参考位置的数据。参考位置的数据的获取过程同以上实施例，在此不再赘述。
此外，在调整前和调整后的参考位置可以相同，也可以不同，例如调整前为以上实施例中的第一参考位置，调整后为以上实施例中第一参考位置或第二参考位置。再如调整前为以上实施例中的第二参考位置，调整后为以上实施例中第二参考位置。
此外，网络设备也可以执行以上步骤S113和S115之一或全部，其后续终端装置可以执行步骤S116。
在以上各个实施例中，终端装置对数据的处理，例如渲染，可以在显示设备中执行，此时，终端装置将接收到的数据提供给显示设备，由显示设备进行处理并显示。此时，该显示设备可以理解为一种终端装置。
本申请实施例还提供用于实现以上任一种方法的装置，例如，提供一种通信装置包括用以实现以上任一种方法中终端装置所执行的各个步骤的单元(或手段)。再如，还提供另一种通信装置，包括用以实现以上任一种方法中网络设备所执行的各个步骤的单元(或手段)。再如，还提供另一种通信装置，包括用以实现以上任一种方法中数据库服务器所执行的各个步骤的单元(或手段)。
