第一方面，提供了一种调整数据传输路径的方法，该方法应用于终端设备，该终端设备和NR基站之间建立有第一链路且该终端设备通过该第一链路和该NR基站传输第一应用的数据，该终端设备和LTE基站之间建立有第二链路，该方法包括：该终端设备检测该第一应用的数据的时延；当该终端设备确定该时延大于或者等于第一预设时延门限值时，该终端设备向该NR基站发送第一指示信息，该第一指示信息用于指示该NR基站断开和该终端设备之间的第一链路；该终端设备通过该第二链路接收来自于该LTE基站的该第一应用的数据，或者，该终端设备通过该第二链路向该LTE基站发送该第一应用的数据。

图1示出了LTE-NR双连接(E-UTRA-NR dual connectivity，EN-DC)组网方式的示意图，该组网方式中以LTE基站(例如，eNB)为主节点(master node)，NR基站(例如，gNB)为辅节点(secondary node)，并且主节点基站连接到4G核心网(evolved packet core，EPC)的双连接方式。其控制面连接和用户面连接的网络架构分别如图1中的(a)和(b)所示，其中，移动管理实体(mobility management entity)通过S1-MME接口与LTE基站相连，服务网关(serving gateway，S-GW)通过S1-U接口与LTE基站相连，S-GW还可以通过S1-U接口与NR基站相连。
图2示出了下一代LTE-NR双连接(NG E-UTRA-NR dual connectivity，NG EN-DC)组网方式的示意图，该组网方式以演进的LTE基站(例如，Ng-eNB)为主节点，NR基站(例如，gNB)为辅节点，并且主节点基站连接到5G核心网的双连接方式。其控制面连接和用户面连接的网络架构分别如图2中的(a)和(b)所示，其中，5GC CP Node通过NG-C接口与演进的LTE基站相连，5GC UP Node通过NG-U接口与演进的LTE基站相连，5GC UP Node还可以通过NG-U接口与NR基站相连。
图3示出了NR-LTE双连接(NR-E-UTRA dual connectivity，NE-DC)组网方式的示意图，该组网方式以NR基站(例如，gNB)为主节点，演进的LTE基站(例如，Ng-eNB)为辅节点，并且主节点基站连接到5G核心网的双连接方式。其控制面连接和用户面连接的网络架构分别如图3中的(a)和(b)所示，其中，5GC CP Node通过NG-C接口与NR基站相连，5GC UP Node通过NG-U接口与NR基站相连，5GC UP Node还可以通过NG-U接口与演进的LTE基站相连。
图4示出了NR双连接(NR-NR dual connectivity，NR-DC)组网方式的示意图，该组网方式以一个NR基站为主节点，另外一个NR基站为辅节点，并且主节点基站连接到5G核心网的双连接方式。其控制面连接和用户面连接的网络架构分别如图4中的(a)和(b)所示，其中，5GC CP Node通过NG-C接口与NR基站相连，5GC UP Node通过NG-U接口与NR基站相连。
本申请应用的场景包括但不限于以下几种：支持4G的网络，例如，只部署了LTE小区的网络；支持5G的网络，例如，只部署了NR小区的网络且支持NR独立(standard alone，SA)组网或NR DC组网的系统架构；同时支持4G和5G的网络，例如，同时部署了LTE小区和NR小区的网络，且支持上述提到的EN-DC组网的系统架构，或NG EN-DC组网的系统架构，或NE-DC组网的系统架构。另外，本申请应用的场景包括基于sub-6GHz部署的网络和基于above-6GHz毫米波部署的网络。
目前商用非独立(non-standalone，NSA)组网网路下行数据传输存在以下几种典型配置，使得下行数据只能在终端设备和NR基站之间的链路上进行数据传输：
(1)下行数据传输不分流，这个是最为常见的配置；
(2)分流场景下，主路径通常配置为NR基站(例如，gNB)与终端设备之间的链路，小数量业务通常达不到分流的门限，因此通常下行数据都是通过主路径传输给终端设备。
应理解，本申请实施例中小数据量业务达不到分流的门限可以指终端设备中缓存的某 些应用的数据量大小达不到预设数据量门限值，和/或终端设备中缓存的某个应用的数据包的数量达不到预设数据包数量门限值。
本申请实施例涉及的一种场景是，主路径为NR基站。对于终端设备中某个特定应用的数据，该数据可以只通过终端设备和NR基站之间的链路传输。
另一种场景是，主路径为NR基站。对于终端设备中某个应用的数据，该数据的大部分可以通过终端设备和NR基站之间的链路传输；剩余小部分数据可以通过终端设备和LTE基站之间的链路传输。
本申请实施例中，对于主路径，可以是传输数据优先级较高的路径。例如，对于传输速率较快的路径可以为主路径；或者，对于传输数据量较大的路径可以为主路径。
应理解，本申请实施例中是以主路径为NR基站和终端设备的路径为例进行说明。当然主路径也可以是LTE基站也同样适用于本申请实施例。
当NR基站(例如，gNB)下小区的信号较差但是LTE基站(例如，eNB)下小区的信号较好时，下行数据通过NR基站进行发送和接收就会出现出数据包时延较大的问题，用户则会感觉到游戏卡顿等，导致用户体验较差。示例性的，NSA外场测试关键应用的时延，某些时延敏感的应用(例如，王者荣耀)的往返时延(round trip time，RTT)增加了200至300ms。此时，NR基站下小区的参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)或者信号与干扰加噪比(signal to interference plus noise ratio，SINR)较差，而LTE基站下小区的RSRP、RSRQ或者SINR较好。
NSA商用网络下行数据传输通常都是配置为不分流且主路径为NR，在满足下述条件时，业务的RTT就会显著增加，用户体验极差：
(1)上述EN-DC、NG EN-DC或者NE-DC下成功添加了NR基站；
(2)NR基站下小区的RSRP、RSRQ或者SINR较差；
(3)LTE基站下小区的RSRP、RSRQ或者SINR较好。
对于上述场景，按照现有的协议，终端设备会一直使用NR小区进行数据接收或者发送，那么RTT时延就会变得很大，进而导致用户体验很差。
针对上述问题，本申请实施例提供了一种调整数据传输路径的方法，可以有效地解决该场景下RTT时延较大的问题。本申请实施例提供的调整数据传输路径的方法，允许渐进尝试多种恢复的策略，以期尽快改善RTT时延，提升用户的体验。
在介绍本申请实施例的调整数据传输路径的方法之前，首先介绍本申请实施例中终端设备或者网络设备进行数据组包时的处理方式。图5示出了本申请实施例中终端设备或者网络设备的协议栈架构。
如图5中的(a)所示，在LTE中终端设备或者网络设备的用户面协议栈架构可以分为分组数据汇聚层协议(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(PHY)层等协议层的功能。终端设备可以在PDCP层和RLC层进行组包。
如图5中的(b)所示，在NR中终端设备或者网络设备的用户面协议栈架构可以分为业务数据适配(service data adaptation protocol，SDAP层、PDCP层、RLC层、MAC层和物理层等协议层的功能。终端设备可以在RLC层进行组包，并且具体地可以按照上行 授权中分配的资源大小进行组包。
图6示出了本申请实施例的调整数据传输路径的方法600的示意性流程图，如图6所示，该方法600包括可以由终端设备、第一网络设备和第二网络设备执行，终端设备和第一网络设备之间的链路为第一链路，终端设备和第二网络设备之间的链路为第二链路，其中，终端设备可以通过第一链路与第一网络设备传输第一应用程序的数据，该方法600包括：
S601，终端设备检测第一应用程序的时延。
示例性的，第一应用程序可以是用户在终端设备中选择的一些应用程序，用户可以为这些应用程序设置可以接受的预设时延阈值。或者，用户可以选择一些应用程序，终端设备可以为这些应用程序设置预设时延阈值。
一般而言，时延阈值可以是运行某一应用程序所能接受的最大时延，例如，当运行游戏应用程序的时候，通常超过160ms就会出现明显卡顿，则可以将160ms设置为游戏类应用程序的时间阈值，因为不同的应用对时延的要求不一样，可以针对不同的应用设置不同的时延。
终端设备在检测第一应用的时延时可以先识别该应用的用户身份证明(user identification，UID)来确定对应的应用程序。以安卓系统为例，一个UID下可以包含多个应用，一个应用下包含多个进程，每个进程用一个进程标识(process ID，PID)进行标识，终端设备可以通过UID或者PID来识别当前运行的应用。
终端设备中可以保存有需要执行方法600的应用的列表。这些应用可以测试得到的，例如可以多个应用进行测试，对于那些数据时延敏感的应用可以保存在某个列表中。之后终端设备可以对于这个列表中的应用执行方法600以及下述方法。
或者，对于某些应用而言，可能只有一部分数据包为数据时延敏感的数据，而其他数据包不是数据时延敏感的数据。那么终端设备也可以针对这些数据时延敏感的数据包执行方法600以及下述方法。
应理解，本申请实施例中，终端设备可以通过第一链路与第一网络设备传输一个或者多个应用程序的数据。终端设备可以同时检测一个或者多个应用程序的时延。
S602，当终端设备确定第一应用程序的时延大于或者等于预设时延阈值时，终端设备向第一网络设备发送第一指示信息，该第一指示信息用于指示第一网络设备断开与终端设备的第一链路。
示例性的，该第一网络设备为NR的基站，该第二网络设备为LTE的基站。那么当终端设备确定第一应用程序的时延大于或者等于预设时延阈值时，终端设备可以向NR的基站发送辅小区组失败信息(secondary cell group failure information，SCG failure)，从而抑制NR测量上报。当第一网络设备接收到SCG failure时，可以确定终端设备通过第一链路接收或者发送数据的时延比较大，那么第一网络设备可以断开和终端设备的第一链路。
NR的SCG failure包括失败的类型以及在辅小区组(secondary cell group，SCG)失败的测量结果，所述测量结果中包括所在波束(同步信号块(synchronization signal block，SSB)、信道状态的参考信号(channel state information RS，CSI-RS)的频率信息，服务小区和邻区的测量结果(包括物理小区标识(physical cell identification，PCI)，在SSB/CSI-RS的RSRP/RSRQ/SINR，所在的SSB/CSI-RS的组号index以及对应的 RSRP/RSRQ/SINR)。
应理解，对于EN-DC、NG EN-DC或者NE-DC的场景，NR基站断开与终端设备之间的链路还可以理解为NR基站释放EN-DC、NG EN-DC或者NE-DC。
一个实施例中，终端设备除了向第一网络设备发送第一指示信息以外，还可以抑制NR邻区B1/B2事件的上报，抑制事件为T1。
应理解，本申请实施例中，终端设备可以向NR的基站发送SCG failure是为了让网络释放EN-DC，终端设备抑制NR邻区B1/B2事件的上报是为了不让网络添加EN-DC(或者，不添加NR小区)。
本申请实施例中，终端设备再向NR基站发送SCG failure以后，如果终端设备不抑制B1/B2事件上报，那么网络设备还可以再获得终端设备上报的B1/B2事件后，继续为终端设备添加NR小区，至于何时添加属于网络设备的实现问题。
一个实施例中，终端设备再向NR基站发送SCG failure以后，网络设备可以继续向终端设备发送测量间隙，以便于终端设备对邻区进行测量。终端设备再获得网络设备发送的测量间隙后，可以忽略该测量间隙(或者，终端设备虽然获取到了测量间隙但是也不进行测量)，那么也就不会向网络设备上报B1/B2事件。这样网络设备也就无法为终端设备添加NR小区。
另一个实施例中，终端设备再向NR基站发送SCG failure以后，网络设备可以继续向终端设备发送测量间隙，以便于终端设备对邻区进行测量。终端设备可以对邻区进行测量，如果测量结果满足B1/B2事件终端设备也不会上报，那么网络设备也就无法为终端设备添加新的NR小区。或者，如果测量结果不满足B1/B2事件，终端设备也不会上报，那么网络设备也不会为终端设备添加新的NR小区。
一个实施例中，终端设备向第一网络设备发送第一指示信息的触发条件除了终端设备检测到第一应用程序的时延大于或者等于预设时延阈值以外，还可以包括终端设备确定以下一个或者多个条件满足：
(1)第二网络设备下小区的RSRP大于或者等于第一预设RSRP门限值；
(2)第二网络设备下小区的RSRQ大于或者等于第一预设RSRQ门限值；
(3)第二网络设备下小区的SINR大于或者等于第一预设SINR门限值；
(4)上下行速率。
也就是说，终端设备在确定第一应用的数据的时延大于预设时延门限值且第二网络设备下的小区信号强度较好时，终端设备可以向网络设备发送第一指示信息。
一个实施例中，终端设备向第一网络设备发送第一指示信息的触发条件除了终端设备检测到第一应用程序的时延大于或者等于预设时延阈值且第二网络设备下小区的信号强度较好以外，还可以包括终端设备确定以下一个或者多个条件满足：
(5)第一网络设备下小区的RSRP小于或者等于第二预设RSRP门限值；
(6)第一网络设备下小区的RSRQ小于或者等于第二预设RSRQ门限值；
(7)第一网络设备下小区的SINR小于或者等于第二预设SINR门限值。
S603，第一网络设备根据该第一指示信息，通过第二网络设备向终端设备发送下行数据，或者，通过第二网络设备接收来自于终端设备的上行数据。
本申请实施例中的调整数据传输路径的方案，在终端设备确定某些应用程序的时延较 大时，终端设备可以通过向网络设备发送第一指示信息，从而终端设备可以通过其他链路和网络设备之间传输数据，有助于及时降低应用程序的时延，从而提升用户体验。
应理解，上述方法600中可以适用于EN-DC、NG EN-DC或者NE-DC的场景，终端设备和NR基站传输某些应用程序的数据，当NR基站下小区的信号较差或者LTE基站下小区信号较好时，终端设备可以通过上报SCG failure来触发网络删除EN-DC、NG EN-DC或者NE-DC，从而降低应用程序的时延，提升用户体验。上述方法也可以适用于第一网络设备和第二网络设备都是NR基站的场景(例如，图4中所示的NR-DC场景)，或者也可以适用于第一网络设备和第二网络设备都是LTE基站的场景。
本申请实施例中，终端设备还可以根据终端设备所需要发送的数据的类型进行断开第一链路，可以对特定的数据包进行标识，所述特定的数据包可以是时间敏感的数据包。例如，终端设备可以先对数据包的标识进行判断。终端设备中可以保存某些对于时延敏感的数据包类型的信息，若终端设备确定传输的数据包为时间敏感的数据包，则终端设备可以继续判断该数据包的时延与预设时延阈值的关系。若该数据包的时延大于或者等于预设时延阈值，那么终端设备可以向网络设备发送第一指示信息。从而使得终端设备和网络设备通过第二链路传输该数据包。
图7示出了本申请实施例中的终端设备内部信令交互过程的示意图。终端设备可以包括应用处理器(application processor，AP)、基带芯片和射频芯片。其中，信令交互的过程包括：
S701，应用处理器确定一个或者多个应用程序。
本申请实施例中，应用处理器可以对需要执行本申请实施例中的方法的应用进行识别。应用处理器可以根据应用的UID判断该应用是否需要进行时延检测；或者，应用处理器也可以根据数据包上的标识信息来确定该数据包是哪一个应用的数据包，并确定是否需要对该应用进行时延检测。
例如，用户正在使用终端设备玩游戏，终端设备可以根据该游戏的UID判断是否需要对该应用执行时延检测。
S702，应用处理器向基带芯片发送该一个或者多个应用的信息。
S703，在基带芯片确定第一应用程序的时延大于或者等于预设时延阈值时，基带芯片可以生成第一指示信息，该第一指示信息用于指示第一网络设备断开与终端设备的第一链路。
示例性的，基带芯片可以判断接收网络设备发送的该应用的数据的时延和预设时延阈值的关系；或者，基带芯片也可以判断向网络设备发送该应用的数据的时延和预设时延阈值的关系。
S704，基带芯片向射频芯片发送该第一指示信息，并由射频芯片向第一网络设备发送该第一指示信息。
下面以EN-DC场景为例介绍本申请实施例的调整数据传输路径的方法。
图8示出了本申请实施例提供的调整数据传输路径的方法800的示意性流程图，该方法800可以由终端设备执行，该方法800包括：
S801，终端设备周期性检测第一应用程序的时延。
S802，终端设备判断防乒乓抑制定时器T2是否正在运行，其中，在防乒乓抑制定时 器T2运行时，终端设备通过NR基站接收第一应用程序的下行数据，或者终端设备向NR基站发送第一应用程序的上行数据。
应理解，本申请实施例中，若防乒乓抑制定时器T2在运行，那么终端设备只会通过与NR基站之间的链路传输第一应用程序的数据，而不会通过与LTE基站之间的链路传输第一应用程序的数据。
若防乒乓抑制定时器T2正在运行，则可以返回S801继续检测第一应用程序的时延。
S803，若防乒乓抑制定时器T2未运行，则终端设备判断第一应用程序的时延是否大于或者等于预设时延阈值。
S804，若终端设备判断第一应用程序的数据的时延大于预设时延阈值，则终端设备继续判断当前是否助于EN-DC场景下。
应理解，本申请实施例中，若终端设备处于EN-DC场景下，则终端设备可以从NR基站接收以第一应用程序的数据。
S805，若终端设备当前处于EN-DC场景下，则终端设备继续检测NR基站下小区的信号强度以及LTE基站下小区的信号强度。若NR基站下小区的信号强度小于或者等于第一预设值且LTE基站下小区的信号强度大于或者等于第二预设门限值，则终端设备向NR基站发送SCG failure,以触发网络释放EN-DC，同时抑制NR邻区的B1/B2事件的上报，抑制事件为T1。
示例性的，当终端设备确定第一应用程序的时延大于预设时延阈值、满足上述条件(1)、(2)、(3)或者(4)中的一个或者多个，且满足上述条件(5)、(6)或者(7)中的一个或者多个时，终端设备可以向NR基站发送SCG failure,以触发网络释放ENDC，同时抑制NR邻区的B1/B2事件的上报。
应理解，以上通过终端设备向NR基站发送SCG failure且抑制NR邻区的B1/B2事件的上报，可以使得NR基站释放EN-DC(或者使得NR基站删除NR小区)，从而使得终端设备通过和LTE基站之间的链路传输第一应用程序的数据，这样有助于降低RTT时延，提升用户体验。此后，网络设备还可以继续为终端设备添加新的NR小区，在添加了新的NR小区后，终端设备还可以通过和NR基站传输第一应用程序的数据。网络设备何时添加新的NR小区属于网络设备的实现。
本申请实施例中，终端设备还可以通过向NR基站发送跟踪区域更新(tracking area update，TAU)信息、去注册(detach)信息或者注册(attach)信息的方式让网络设备删除NR小区。例如，终端设备可以在TAU信息的终端设备能力信息中携带终端设备不支持EN-DC能力的信息使得NR基站删除NR小区。此后，终端设备可以在和LTE基站之间的链路上传输第一应用程序的数据。如果终端设备确定在和LTE基站之间的链路上传输第一应用程序的数据的时延较大且希望恢复和NR基站的链路时，就需要终端设备向NR基站再次发送其能力信息，能力信息中可以携带终端设备支持EN-DC能力的信息。
S806，若终端设备当前未处于EN-DC场景下，且终端设备已经抑制了NR邻区的B1/B2事件的上报，则终端设备解除抑制，同时开启防乒乓定时器T2。
本申请实施例的方法800中，若终端设备当前未处于EN-DC场景下，那么终端设备此时和LTE基站建立了链路。如果终端设备判断在和LTE基站的链路上传输第一应用程序的数据的时延大于或者等于预设时延阈值，终端设备可以解除抑制。那么网络设备可以 继续为终端设备添加NR小区，从而可以让终端设备和NR基站建立链路且通过该链路传输第一应用程序的数据。这样有助于降低RTT时延，提升用户体验。
S807，若S803中终端设备判断第一应用程序的时延小于预设时延阈值，且终端设备已经抑制了NR邻区的B1/B2事件的上报，则终端设备解除抑制，允许上报邻区的B1/B2事件。
一个实施例中，对于上述方法800中解除抑制条件外，在小区或者定时提前(timing advance，TA)改变等场景下，终端设备均可以解除抑制。
本申请实施例中，在ENDC场景下，NR小区信号较差，LTE服务小区信号较好，下行数据传输走NR时，方法800中可通过上报SCG failure来触发网络删除ENDC，通过信号较好的LTE小区来接收下行数据，从而降低RTT时延，提升用户体验。
图9示出了本申请实施例提供的调整数据传输路径的方法900的示意性流程图，该方法900可以由终端设备执行，该方法900包括：
S901，终端设备周期性检测第一应用程序的时延。
S902，终端设备判断防乒乓抑制定时器T2是否正在运行，其中，在防乒乓抑制定时器T2运行时，终端设备通过NR基站接收第一应用程序的下行数据，或者终端设备向NR基站发送第一应用程序的上行数据。
若防乒乓抑制定时器T2正在运行，则可以返回S801继续检测第一应用程序的时延。
S903，若防乒乓抑制定时器T2未运行，则终端设备判断第一应用程序的时延是否大于或者等于预设时延阈值。
S904，若终端设备判断第一应用程序的时延大于预设时延阈值，则终端设备继续判断当前是否助于EN-DC场景下。
S905，若终端设备当前处于EN-DC场景下，则终端设备继续检测NR基站下小区的信号强度以及LTE基站下小区的信号强度。若NR基站下小区的信号强度小于或者等于第一预设值且LTE基站下小区的信号强度大于或者等于第二预设门限值，则终端设备向NR基站发送SCG failure,以触发网络释放ENDC，同时抑制NR邻区的B1/B2事件的上报，抑制事件为T1。
应理解，S901-S906可以参考上述S801-S806的过程，为了简洁，在此不再赘述。
S906，若终端设备当前未处于EN-DC场景下，终端设备继续判断是否已经关闭EN-DC能力。
相比于上述方法800，方法900中终端设备在确定未处于EN-DC场景下(终端设备此时只和LTE基站建立了链路)时，终端设备可以继续判断是否已经关闭了EN-DC能力。
S907，若终端设备已经关闭了EN-DC能力，则终端设备可以恢复ENDC能力，并开启防乒乓抑制定时器T2。
若终端设备已经关闭了EN-DC能力，那么终端设备可以恢复EN-DC能力。这样在恢复EN-DC能力后，终端设备可以继续通过终端设备与NR基站之间的链路传输第一应用程序的数据，从而可以降低RTT时延，提升用户的体验。
应理解，本申请实施例中，防乒乓抑制定时器T2的作用是为了防止频繁抑制EN-DC和解除抑制。
S908，若终端设备没有关闭EN-DC能力，则终端设备关闭EN-DC能力，并开启恢复 定时器T3。
若终端设备没有关闭EN-DC能力，那么此时终端设备虽然只通过和LTE基站之间的链路传输第一应用程序的数据，但是在传输的过程中LTE基站其实还是会通过其NR模块来进行数据的传输，由于兼容性的问题会导致第一应用程序的数据时延较大。如果终端设备关闭了EN-DC能力，那么LTE基站会通过其LTE模块来进行数据的传输，由于兼容性好可以改善第一应用程序的数据时延，从而可以降低RTT时延，提升用户的体验。
本申请实施例中，T3定时器的作用是为了解除抑制，若不满足其他解除抑制的条件，则终端设备可以在定时器超时后解除抑制。
S909，若S903中终端设备判断第一应用程序的时延小于预设时延阈值，则：
若终端设备未关闭EN-DC能力，即仅抑制了B1/B2事件的上报，则终端设备解除抑制，允许上报邻区的B1/B2事件；或者，
若终端设备已经关闭了EN-DC能力，则恢复EN-DC能力；或者，
终端设备也可以开启防乒乓抑制定时器T2。
上述方法800和方法900中提到了恢复或者关闭终端设备的EN-DC能力，下面对终端设备恢复或者关闭EN-DC能力的做法进行详细描述。
终端设备关闭EN-DC能力的方式包括但不限于以下几种：
方式一
终端设备通过主动上报SCG failure，可以触发网络设备删除NR小区。
方式二
终端设备在空闲态(idle)通过触发跟踪区域更新(tracking area update，TAU)，携带“UE radio capability information update needed”的信元(information element，IE)通知网络设备重新查询终端设备的能力。终端设备在上报能力时告知网络设备不支持ENDC。一个实施例中，终端设备可以在连接态时先释放链路回到空闲态，然后再触发TAU。
方式三
终端设备向网络设备发送去注册消息(detach)，然后再发起注册(attach)流程。网络设备在查询终端设备的能力时，终端设备在上报能力时告知网络设备不支持ENDC。
终端设备打开或者恢复ENDC能力的方式包括但不限于以下几种：
方式一
如果终端设备之前是通过上报SCG failure的方式释放了EN-DC，那么终端设备只能解除本地抑制，至于网络设备何时添加NR小区，就需要看网络设备的实现了。
方式二
若是通过TAU的方式关闭了EN-DC能力，仍然可以通过相同的方式触发网络重新查询UE能力，在上报UE能力时告知网络支持EN-DC；
方式三
若是通过detach/attach方法关闭的EN-DC能力，则仍通过该方法，上报支持ENDC。
本申请实施例中，在EN-DC场景下，NR小区信号较差，LTE服务小区信号较好，下行数据传输走NR时，方法800中可通过上报SCG failure来触发网络删除ENDC，通过信号较好的LTE小区来接收下行数据，从而降低RTT时延，提升用户体验。
在非EN-DC场景下，通过TAU/detach/attach相关流程实现关闭及打开ENDC能力的 方法，进而解决该场景下的RTT时延大的问题。
图10示出了本申请实施例提供的一种应用场景的示意图。
如图10中的(a)所示，用户正在使用手机玩游戏，此时手机上的网络制式显示为“5G”，该手机处于EN-DC场景下。也就是说，手机正在和NR基站传输该游戏应用的数据包。手机和NR基站之间的路径可以为主路径。手机的应用处理器确定当前运行的该游戏应用在可以执行上述方法的应用列表中。手机的应用处理器可以向基带芯片指示该应用需要进行时延检测。
某一时刻，当手机基带芯片检测到关于该游戏应用的时延大于或者等于预设时延阈值时，手机的基带芯片可以生成第一指示信息，该第一指示信息可以用来指示断开与NR基站之间的链路。手机的基带芯片向射频芯片发送该第一指示信息并由射频芯片向NR基站发送。NR基站在接收到第一指示信息后，可以断开与手机之间的路径。处于EN-DC场景下的手机可以通过LTE基站向终端设备发送关于该游戏应用的数据包；或者，手机可以通过与LTE之间的路径发送关于该游戏应用的数据包。这个时候手机上显示的网络制式为“4G”。
