Description

一种数据传输优化方法、终端及网络设备 技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输优化方法、终端及网络设备。
背景技术
小区边缘的性能问题是所有移动网络面临的重要挑战，如同频干扰使得小区边缘的吞吐率较小区中心区域的吞吐率相差数倍，尽管有多种技术如协同多点传输技术(Coordinative Multiple Point，CoMP)、传输时间间隔绑定技术(TTI Bunding)致力于提升边缘用户吞吐率，但小区边缘的吞吐率相对中心区域的吞吐率差距仍然很大。因此终端在多小区之间移动时，如从一个小区的小区中心向小区边缘移动，再移动到另一个小区的小区边缘，继而进入另一个小区的小区中心，业务速率会剧烈波动，这将严重影响对业务速率要求较高的业务质量，如视频业务质量，尤其当终端新进入的小区负载较重时，切换时延将造成业务质量的急剧恶化，如发生视频卡顿。

下面将结合附图，对本申请实施例进行描述。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、网络设备，可以称之为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，包括但不限于：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(BaseBand Unit，BBU)、无线保真(Wireless Fidelity，WIFI)接入点(Access Point，AP)，传输点(transmission and receiver point，TRP或者transmission point，TP)等。
2)、终端，是一种向用户提供语音和/或数据连通性的设备，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处 理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station，MS)，终端(Terminal Equipment)，传输点(transmission and receiver point，TRP或者transmission point，TP)等等。
3)、交互，本申请中的交互是指交互双方彼此向对方传递信息的过程，这里传递的信息可以相同，也可以不同。例如，交互双方为基站1和基站2，可以是基站1向基站2请求信息，基站2向基站1提供基站1请求的信息。当然，也可以基站1和基站2彼此向对方请求信息，这里请求的信息可以相同，也可以不同。
4)、“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
5)、名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。信息(information)，信号(signal)，消息(message)，信道(channel)有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例提供的数据传输优化方法，可应用于图1所示的无线通信系统中，如图1所示，终端通过基站等网络设备接入无线网络，且通过核心网(Core Network，CN)设备实现终端与外部网络的通信。该系统中，基站之间可以进行信息交互，例如在长期演进(Long Term Evolution，LTE)系统中，基站之间的接口称为X2接口，且基站之间可以通过X2接口进行信息交互。此外，基站与终端之间的接口称为Uu口，又称之为空口，基站与终端之间通过空口进行通信。基站与CN设备之间的接口称为S1接口，基站与CN设备通过S1接口进行通信，CN设备可以包括移动性管理实体(Mobility Management Entity，MME)和服务网关(Serving Gateway，S-GW)，基站与S-GW之间实现用户面信息交互，基站与MME之间实现控制面信息交互。
可以理解的是，无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络。典型的2G网络包括全球移动通信系统(global system for mobile communications/general packet radio service，GSM)网络或者通用分组无线业务(general packet radio service，GPRS)网络，典型的3G网络包括通用移动通信系统(universal mobile telecommunications system，UMTS)网络，典型的4G网络包括长期演进(long term evolution，LTE)网络。其中，UMTS网络有时也可以称为通用陆地无线接入网(universal terrestrial radio access network，UTRAN)，LTE网络有时也可以称为演进型通用陆地无线接入网(evolved universal terrestrial radio access network，E-UTRAN)。根据资源分配方式的不同，可以分为蜂窝通信网络和无线局域网络(wireless local area networks，WLAN)，其中，蜂窝通信网络为调度主导，WLAN为竞争 主导。前述的2G、3G和4G网络，均为蜂窝通信网络。本领域技术人员应知，随着技术的发展本申请实施例提供的技术方案同样可以应用于其他的无线通信网络，例如4.5G或者5G网络，或其他非蜂窝通信网络。为了简洁，本申请实施例有时会将无线通信网络简称为网络。
蜂窝通信网络是无线通信网络的一种，其采用蜂窝无线组网方式，在终端和网络设备之间通过无线通道连接起来，进而实现终端在移动过程中可相互通信。其主要特征是终端的移动性，并具有越区切换和跨本地网自动漫游功能。
终端移动过程中，由于小区边缘性能问题的存在，导致业务速率会剧烈波动，这将严重影响对业务速率要求较高的业务质量，如视频业务质量，尤其当终端新进入的小区负载较重时，切换时延将造成业务质量的急剧恶化，如发生视频卡顿。
本申请实施例中，终端预先生成轨迹上下文，在该轨迹上下文中包括有终端历史时间移动经过的轨迹路线及轨迹路线上的待优化线段，该待优化线段可以理解为是存在小区边缘性能问题的位置，终端在所述待优化线段内移动时预定义测量量的取值符合预设的门限值取值范围，所述测量量包括但不限于信号质量、上行吞吐率或者下行吞吐率，故终端在移动过程中，若确定沿轨迹上下文中包括的轨迹路线移动且到达所述轨迹路线上的待优化线段，则向网络设备发送数据传输优化指示，以指示所述网络设备执行数据传输优化处理操作，进而保障对速率要求较高的业务(如视频业务)不受终端移动过程的影响，提高终端移动到小区边缘时的业务质量。
本申请实施例以下将结合实际应用对本申请涉及的数据传输优化方法进行说明。
图2所示为本申请实施例提供的一种数据传输优化方法的实施流程图，参阅图2所示，包括：
S101：终端预先生成轨迹上下文。
其中，轨迹上下文中包括有终端历史时间移动经过的轨迹路线及轨迹路线上的待优化线段，该待优化线段可以理解为是存在小区边缘性能问题的位置，终端在所述待优化线段内移动时预定义测量量的取值符合预设的门限值取值范围，所述测量量包括但不限于信号质量、上行吞吐率和下行吞吐率，可以是其中的至少一个。
终端预先生成的轨迹上下文可有多个，轨迹上下文的生成方式包括但不限于历史数据学习、最小二乘法、大数据聚类等方法。例如终端可记录每天移动的轨迹路线，如图3所示，用户携带终端每天从住处前往单位，经过的轨迹路线为从A->F所表示的路线，终端记录该A->F的轨迹路线，并记录所述轨迹路线上所有的待优化线段。其中，记录的所有待优化线段可按照终端进入的先后顺序排列。在图3所示的A->F的轨迹路线中，终端从小区1的小区中心向小区1边缘移动，移动到小区2的小区边缘，并进入小区2的小区中心，再由小区2的小区中心向小区2边缘移动，移动到小区3的小区边缘，并进入小区3的小区中心，待优化的线段可以包括小区1与小区2的边缘位置(待优化线段BC)，小区2与小区3的边缘位置(待优化线段DE)，待优化线段BC和待优化线段DE内预定义测量量的取值符合预设的门限值取值范围。预定义测量量可以是信号质量如参考信号接收功率(Reference Signal Receiving Power，RSRP)或者参考信号接收功率(Reference Signal Receiving Quality，RSRQ)，也可以是用户的下行速率或者上行发送速率。预设的门限值取值范围可以是网络设备配置的，也可以是终端的经验值，或者预定义值。例如，所述测量量为信号质量、上行吞吐率或者下行吞吐率的情况下，该测量量取值小于预设门限值；所述测量量为小区负 载的情况下，该测量量取值可大于预设门限值。

可选的，终端在判断某个待优化线段中是否发生小区切换时，除了依据是否有切换测量事件上报的记录，还可以通过判断预定时间内是否有切换测量事件对应的切换命令下达。
