Description

一种网络连接方法、系统及相关装置
本申请要求于2020年07月31日提交中国专利局、申请号为202010761966.2、申请名称为“一种网络连接方法、系统及相关装置”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
本申请涉及通信技术领域，尤其涉及一种网络连接方法、系统及相关装置。
背景技术
LTE在R12标准中引入双连接的概念，即用户设备(user equipment，UE)在无线资源控制(radio resource control，RRC)连接状态下可同时利用两个基站独立的物理资源进行传输。LTE双连接技术拓展了载波聚合的应用，能有效提升网络容量，提高网络切换功率等能力。
在第五代移动通信网络(5th generation mobile networks，5G)的新空口(new radio，NR)网络部署初期，非独立组网(non-standalone)的组网方式将是全球大多数运营商选用的方式。
NSA组网方式也称为4G-5G无线接入双连接(EUTRN-NR dual connectivity，EN-DC)，主要涉及4G的E-UTRAN接入网(也称为LTE接入网)和5G的新随机接入制式(new random access technology，NR)接入网(简称为NR接入网)，从而使得5G网络在部署时可借助已有4G的LTE覆盖，避免网络资源的浪费。
在EN-DC组网方式中，UE可同时与4G基站(可称为eNB)和5G基站(可称为En-gNB)连接，在4G和5G的紧密互操作下获得高速率、低延迟的无线传输服务。相比于单接入网工作模式而言(例如仅利用4G的LTE技术通信)，电子设备的双接入网工作模式(例如同时利用4G的LTE技术和5G技术通信)将导致UE功耗较大。且对于一些低用网需求的场景而言，LTE接入网即可保证电子设备的连网需求。对于智能手机等电子设备，会经常在高网速需求的场景和低网速需求的场景之间切换，如果仍采用LTE-NR双连接技术无疑会造成网络资源的浪费、电子设备功耗的增加。
发明内容
本申请提供了一种网络连接方法及相关装置，实现了可通过UE辅助信息中的过热保护(overheating)字段或最大辅载波(maxCC)等字段指示网络侧快速建立NR链路连接或释放NR链路连接。

下面介绍本申请涉及的一种EN-DC网络架构。
图1示出了本申请中涉及的一种EN-DC网络架构。
如图1所示，该EN-DC网络架构包括主基站MeNB(4G LTE接入网络中的基站)、辅基站SgNB(5G NR的基站)、电子设备(可称为UE)、移动管理实体(mobility management entity，MME)以及服务网关(serving-gateway，S-GW)。其中，主基站、辅基站和电子设备各自的数量并不做限定，这里以一个作为示例，并不构成限定。
基站(具体可为MeNB或SgNB)，为用户提供空中接口，电子设备UE通过无线连接到基站。进一步基站通过有线连接到运营商的核心网，实现业务通信。
电子设备UE，指支持连网的设备，其可包括但不限于手机、平板电脑(table personal computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(mobile internet device，MID)、可穿戴式设备(wearable device)以及其他支持和网络通信的设备。
MME，属于核心网的网元，主要负责提供NSA组网的信令传输、用户鉴权和漫游管理等。
服务网关(serving gateway，S-GW)，主要负责本地网络用户数据的处理，例如分组数据的路由或转发等。
如图1所示，主基站MeNB和移动管理实体MME之间通过S1-C接口连接，主基站MeNB和服务网关S-GW之间通过S1-U接口连接。主基站MeNB和辅基站SeNB之间可通过X2接口连接，辅基站SeNB还可根据实际业务需求通过S1-U接口与S-GW连接。在通信过程中，主基站MeNB通过X2接口与辅基站SeNB进行通信协调后可产生RRC消息，然后转发给UE，以实现网络系统信息的广播、切换、测量配置和测量报告的上报等功能，不做限定。
下面介绍本申请中涉及的电子设备的接口协议分层。
图2示出了本申请实施例提供的一种电子设备的接口协议分层通信示意图。在实际应用中，接口是指不同网元之间的信息交互方式，不同接口之间通信时采用的接口协议可不相同。目前，无线制式的接口协议分为三层：物理层(physical layer，PHY)、数据链路层和网络层。
如图2所示，物理层PHY位于最底层，主要负责处理调制解调、天线映射或其他电信物理层功能。
数据链路层包括分组数据汇聚协议(packet date convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层和媒体访问控制(mediaaccess control，MAC)层。其中，PDCP层主要负责执行包头压缩，以减少无线接口传输的比特流量。RLC层主要负责分段和连接、高层数据的顺序控制等处理。MAC层主要负责混合自动重传请求(hybrid automatic repeat request，HARQ)重传和上下行调度等。在实际应用中，LTE-NR双连接技术具体可在L2数据链路层实现载波聚合的承载和分离，具体如上文所述载波聚合具体承载在媒体访问控制(medium access control，MAC)层分离，双连接的承载分离位于分组数据汇聚协议(packet data convergence protocol，PDCP)层实现。
网络层包括非接入层(non-access stratum，NAS)和RRC层。其中，非接入层NAS可用于传输用户信息或控制信息，例如4G/5G通信链路或业务的建立、释放以及移动性管理信息等。NAS层以下的协议层也可称为接入层(access stratum，AS)。RRC层支持电子设备UE和基站eNB间多种功能的信令协议，广播NAS层和AS层的系统消息，RRC连接建立、保持和释放，端到端无线承载(例如UE到网络侧间无线接入网链路)的建立、修改和释放，包括UE测量报告、小区切换和重选等功能在内的移动管理等。在实际应用中，UE可通过L3网络层与网络侧通信，以实现4G和5G接入网的建立、释放等操作，具体在本申请下文进行详述。
下面介绍本申请中涉及的EN-DC组网技术中的用户面协议栈架构。
EN-DC组网技术中定义有主小区群(master cell group，MCG)和辅小区群(secondary cell group，SCG)，并根据数据分离和转发方式不同，将数据承载分为三类：MCG承载、SCG承载和分离Split承载。其中，主小区群MCG是指至少一个4G LTE接入网的主基站MeNB所在小区的集群，辅小区群是指至少一个5G NR的辅基站SgNB所在小区的集群。
图3示出了本申请实施例中提供的UE侧的数据承载链路的通信示意图。
如图3所示，UE侧可以感知三种数据承载，分别为：MCG承载、SCG承载和分离(Split)承载。其中，MCG承载指数据从核心网的S-GW路由到主基站MeNB，并由MeNB直接转发给UE。SCG承载指数据从核心网的S-GW路由到辅基站SeNB，并由SeNB直接转发给UE。Split承载指数据在基站侧分离，可由主基站MeNB或辅基站SeNB向UE转发，也可由主基站MeNB或辅基站SeNB按预设的分离比例同时为UE传输数据，提供服务。
当UE感知数据承载为MCG承载时，数据通信时所用的通信链路(也可称MCG链路)为：LTE PDCP/NR PDCP-LTE RLC-LTE MAC。当UE感知数据承载为SCG承载时，数据通信时所用的通信链路(也可称为SCG链路)为：NR PDCP-NR RLC-NR MAC。当UE感知数据承载为Split承载时，数据通信时所用的通信链路(也可称为Split链路)为：NR  PDCP-LTE RLC-LTE MAC，或者NR PDCP-NR RLC-LTE MAC。其中，由于SCG链路仅使用到5G NR的网络资源，该SCG链路也可称为NR链路。MCG链路使用到4G LTE的网络资源，该MCG链路也可称为LTE链路。
图4示出了本申请实施例中提供的网络侧的数据承载链路的通信示意图。
如图4所示，网络侧感知数据承载的方式有6种，分别为：主节点(master node，MN，具体可指主基站MeNB)终止的MCG承载、MN终止的SCG承载、MN终止的分离Split承载、辅节点(secondary node，SN，具体可指辅基站SeNB)终止的MCG承载、SN终止的SCG承载和SN终止的分离Split承载。
其中，MN终止的承载是指PDCP层在主基站MeNB的无线承载，不在辅基站SeNB的无线承载。反之，SN终止的承载是指PDCP层在辅基站SeNB的无线承载，不在主基站MeNB的无线承载。当网络侧感知的数据承载为MN终止的MCG承载时，数据通信时的通信链路为：LTE PDCP/NR PDCP-LTE RLC-LTE MAC。当网络侧感知的数据承载为MN终止的Split承载时，数据通信时的通信链路为：NR PDCP-LTE RLC-LTE MAC，或者NR PDCP-NR RLC-NR MAC。具体可根据实际需求选择，不做限定。关于网络侧感知的各种数据承载对应的通信链路，具体如图4所示，这里不再赘述。
5G NSA组网下，EN-DC是一个重要的使用场景。电子设备通过LTE和NR两个接入网域网络侧进行数据通信，在两个接入网络发送和接收业务数据包，显著提升用户数据体验。在EN-DC模式，电子设备在LTE和NR制式同时工作时，两种制式相关器件需要同时工作，相比单模式工作，电子设备功耗较高，且容易促使温度升高。
在一些场景中，例如灭屏，或者应用低速率场景，或者无数据流量，或者开启省电模式等场景下，电子设备在LTE就可以满足业务需要，需要优先考虑功耗因素，释放NR连接。另外，由于电子设备温度过高，出于对电子设备和电子设备使用人的保护，也需要释放NR SCG。
图5示出了本申请中提供的一种触发网络释放NR连接的流程示意图。
如图5所示，电子设备UE可以包括应用处理器AP、NAS层、RRC层。其中，RRC层具体包括LTE RRC(简称为LRRC)和NR RRC(简称为NRRC)。电子设备释放NR SCG的过程可以如下：
1、电子设备的应用处理器AP在检测到需要释放NR SCG时，可以指示NAS层释放SCG。
2、NAS层可以通知RRC层释放NR的接入层(access stratum，AS)资源。
3、RRC层可以向网络侧设备发送SCG failure消息，该SCG failure消息可用于通知网络侧设备释放SCG。
4、网络侧设备接收到电子设备的RRC层发送的SCG failure消息之后，网络侧设备可以与电子设备的RRC层断开NR链路。RRC层可以关闭NR测量。
5、电子设备的RRC层在断开NR链路，关闭NR测量之后，可以通知NAS层该NR链路被删除，LRRC连接不释放。
通过上述电子设备上报SCG failure消息给网络侧设备的方式，可以触发网络侧设备释放NR SCG。但是，电子设备频繁上报SCG failure消息给网络侧设备，会导致网络侧异常指标升高，网络无法判断网络异常原因，同时现网也存在终端上报SCG failure，网络也不释放SCG的情况。
在一些场景中，电子设备已经释放了NR SCG，但电子设备需要使用5G业务时，电子设备需要尽快恢复建立5G连接，保证应用的网速需求和用户体验。
图6示出了本申请中提供的一种触发网络建立NR连接的流程示意图。
如图6所示，电子设备建立NR连接的过程可以如下：
1、电子设备可以启动大流量应用，并与主基站MeNB进行大流量的数据交互。
2、主基站可以根据电子设备的数据流量信息，确定出电子设备需要添加辅基站SgNB。
3、主基站可以判断辅基站添加间隔是否超时(例如超过60s)。
4、若辅基站添加间隔超时(例如超过60s)，主基站可以发送B1事件测量信令给电子设备。
5、电子设备在接收到B1事件测量信令后，可以在异系统邻区信号大于指定门限时，发送B1事件测量报告给主基站。其中，B1事件测量报告中包括有电子设备测量到信号大于指定门限的异系统邻区。
6、主基站可以基于B1事件测量报告为电子设备选择出合适的5G邻区。
7、主基站在为电子设备选择出合适的5G邻区后，可以发送辅基站添加请求给辅基站。
8、辅基站接收到主基站发送的辅基站添加请求后，可以返回辅基站添加响应给主基站。
9、主基站可以发送辅基站添加指示给电子设备。
10、电子设备可以根据辅基站添加指示添加5G基站为辅基站。
通过上述方式建立NR连接时，电子设备需要被动等待主基站启动NR SCG添加流程。其中，主基站启动NR SCG添加时周期性的，即便电子设备已经满足NR SCG的添加条件，主基站也要等到下一个添加间隔超时以后才会为电子设备添加NR SCG。例如，主基站的NR SCG添加间隔可以为60s，电子设备最长会等待60s才能连接上5G网络。在一些可能的场景中，例如，电子设备由于小流量，触发网络侧的主基站释放了NR SCG。之后，电子设备开启测速应用开始测量移动网络速度，但是由于NR SCG添加间隔未到，网络侧的主基站此时不启动NR SCG添加流程，导致电子设备测速只有LTE速率。在其他一些可能的场景中，电子设备的视频软件采用分段缓冲机制从网络上下载视频，比如，一个1吉字节(gigabyte，GB)的视频分为5段数据片进行缓冲，每段数据片的数据量为200兆字节(megabytes，MB)。电子设备完成第一个200MB的数据片缓冲后，会暂停缓冲或小流量缓冲，从而电子设备会释放NR SCG，在第一个200MB的数据片播放完成后，电子设备才开始下载第二个200MB的数据片，此时，由于NR SCG的添加间隔还未超时，网络侧的主基站不启动NR SCG的添加流程，电子设备只能用LTE网络下载，网速不够快，会导致视频播放卡顿。因此，通过上述方式恢复连接NR，会导致电子设备在需要使用5G网络时，无法及时连接上5G网络。
图7示出了本申请中提供的另一种触发网络建立NR连接的流程示意图。
如图7所示，电子设备建立NR连接的过程可以如下：
1、电子设备的辅基站被释放。
2、电子设备确定需要添加辅基站。
3、电子设备释放与主基站之间的RRC连接。
4、电子设备向主基站触发服务请求流程。
5、主基站与电子设备建立RRC连接，并为电子设备添加辅基站。
在上述建立NR连接的方式中，电子设备需要主动本地释放RRC连接，再重新与主基站建立RRC连接，触发网络配置添加NR SCG。其中，在电子设备本地释放RRC连接之后，会造成一定时间段内，电子设备断开网络连接，应用无法获取网络数据，造成用户可感知的卡顿，影响用户体验，还可能导致电子设备丢失寻呼，并且频繁触发该过程还可能造成网络认为电子设备异常，导致其他兼容性问题发生。
因此，本申请实施例提供了一种网络连接方法，电子设备可以通过向网络侧发送UE辅助信息，触发网络侧与电子设备快速建立NR链路连接或释放NR链路连接。具体可使用UE辅助信息中的过热保护(overheating)字段或最大辅载波(maxCC)等字段指示网络侧建立NR链路连接或释放NR链路连接。这样，电子设备在LTE-NR双连接情况下，需要释放NR连接时，快速触发网络侧释放NR SCG，以降低功耗。电子设备在单LTE连接情况下，需要建立LTE-NR双连接的时，电子设备可以快速触发网络侧添加NR SCG，以快速恢复LTE-NR双连接，提高数据传输速率。
在低网速应用场景下，电子设备只使用LTE网络即可满足网速要求，为降低功耗，就需要释放与网络侧建立的NR链路。在高网速应用场景下，电子设备只是单连接至LTE网络时无法满足网速要求，电子设备需要与网络侧建立LTE-NR双连接。其中，低网速应用场景可以指电子设备的用网需求较低的应用场景，具体可指电子设备进行数据传输的速率(简称为数据传输速率)较小，或电子设备所需传输的数据包的大小较小的应用场景。反之，电子设备的用网需求较高的应用场景可称为高网速应用场景。
本申请实施例中，电子设备处于低网速应用场景时，可以称之为电子设备满足第一预设条件；电子设备处于高网速应用场景时，可以称之为电子设备满足第二预设条件。
示例性地下面给出如下几种可能的低网速应用场景：
1、电子设备处于灭屏状态。
本申请中，电子设备的屏幕状态可分为亮屏状态、灭屏状态。在实际应用中亮屏状态具体可以包括亮屏解锁状态和亮屏锁屏状态。
其中，电子设备的屏幕状态具体可通过软件程序或硬件检测方式识别。以软件程序检测方式为例，电子设备可通过电源管理(powermanager)下的人机交互(isInteractive)代码中定义的屏幕显示值(isScreenOn)先确定屏幕的亮灭状态，例如当isScreenOn为true时，表示电子设备处于亮屏状态；反之，确定电子设备处于灭屏状态。在确定到电子设备处于亮屏状态后，电子设备可再通过屏幕锁定代码(isScreenLocked)检测获知电子设备是否进 一步被锁定，如果锁定则可确定电子设备处于锁屏状态，具体地电子设备可处于亮屏锁屏状态；否则，确定电子设备处于亮屏状态，具体地电子设备处于亮屏解锁状态。
或者，电子设备可通过自身系统发送的安卓Android广播消息，确定电子设备的屏幕状态。具体地，当Android广播消息用于指示屏幕亮屏时，可确定电子设备处于亮屏状态；当用于指示屏幕灭屏时，可确定电子设备处于灭屏状态；当用于指示屏幕锁屏时，可确定电子设备处于锁屏状态等等。关于电子设备的屏幕状态的识别方式可有多种，本发明这里不做一一列举。
电子设备在灭屏状态下，电子设备通常没有数据收发，或者仅保持必要的保证应用程序处于唤醒状态的数据包，例如心跳测试包或者监听数据包等，通常这一类型的数据包是周期性的收发并且数据包的大小也比较小。在上述情况下，可以视为电子设备对网络参数等要求较低，用网需求较低，电子设备对网速的要求不高。在一些情况下，电子设备也可以支持后台应用的运行，但对网速的要求也不高，例如，音乐应用后台从网络下载音乐并播放。电子设备单连接至LTE网络就可以满足后台应用的需求。
2、电子设备处于亮屏状态，且低网速运行，即电子设备的数据传输速率小于或等于预设速率。
本申请中，低网速是指电子设备的数据传输速率较小，例如小于或等于预设速率。具体地，该低网速具体可指电子设备的上行数据的传输速率较小，例如小于或等于第一预设速率；也可指电子设备的下行数据的传输速率较小，例如小于或等于第二预设速率；还可指包括电子设备的上行数据和下行数据在内的所有数据的传输速率较小，例如小于或等于第三预设速率等。为方便描述，不论是上行数据的传输速率还是下行数据的传输速率，亦或是包括上行数据和下行数据在内的所有数据的传输速率，本申请均统称为数据的传输速率，简称为数据传输速率。该数据传输速率是指单位时间内电子设备支持传输数据的比特数，例如50比特每秒(bit/s)。
该预设速率可为系统自定义设置的，例如根据用户喜欢或实际需求自定义设置的，或者根据大量实验数据统计获得的数值等。本申请涉及的第一预设速率、第二预设速率以及第三预设速率均为系统自定义设置的，它们可以相同、也可不相同，不做限定。
在实际应用中，电子设备低网速运行的场景有很多，下面示例性给出三种。
第一种，电子设备可以开启低网速应用运行的功能或关闭高网速应用运行的功能。具体地，为满足低网速的用网需求，电子设备可在省电模式中进行如下应用的功能设置：允许低网速应用运行或禁止高网速应用运行，即开启低网速应用运行的功能或关闭高网速应用运行的功能。可理解地，在关闭电子设备中高网速应用运行的功能后，电子设备中只允许低网速应用运行。由于这些低网速应用中允许的数据传输速率较小，此时电子设备可确定电子设备处于低网速运行中。可选地，当电子设备中同时运行多个低网速应用时，它们的数据传输速率总和也比较小，例如小于预设速率，同样可满足低网速用网需求，此时仍确定电子设备处于低网速运行中。
其中，低网速应用是指电子设备中安装的对数据传输速率要求较低的应用，例如要求应用中待传输数据的传输速率小于第四预设速率等。该低网速应用具体可为系统自定义设 置的，也可为用户手工自定义设置的，例如照相机、电话、短信、备忘录等应用。
相应地，高网速应用是指电子设备中安装的对数据传输速率要求较高的应用，例如要求数据传输速率大于或等于第五预设速率。该高网速应用同样也可为系统自定义设置的，或用户根据个人偏好自定义设置的，例如音乐应用和视频应用等。
可选地，为排除电子设备是短暂低网速运行、或排除误判等情况，电子设备增加时长判断条件。具体地，电子设备可获取电子设备的数据传输速率小于或等于预设速率的持续时长，当该持续时长大于或等于一定阈值(例如1分钟)等，此时可确定电子设备处于低网速运行中。否则，仍然确定电子设备不处于低网速运行。即是，电子设备处于低网速应用场景的识别条件具体可为：电子设备处于亮屏状态下，且电子设备在一段时长内的数据传输速率均小于或等于预设速率。
第二种，电子设备和其他设备交互心跳包，以维持正常的通信连接。具体地，当电子设备不与其他设备(例如基站)进行业务通信时，即电子设备无需传输业务数据，为维持电子设备和其他设备之间的通信连接，通常电子设备可以周期性地向其他设备发送心跳包，以通知电子设备与其他设备保持通信连接。在实际应用中，该心跳包的数据传输速率通常比较小，例如几kb/s。该心跳包的大小也比较小，例如几kb。通常在不携带业务数据的情况下，该心跳包可为空包，即仅携带包头、不携带业务数据。
第三种，电子设备处于低网速运行的场景，例如游戏场景、导航场景。示例性地，在游戏场景中，电子设备正在运行游戏应用。在实际应用中，游戏应用仅对电子设备的应用处理器(AP)的运行速率要求较高，相比而言对电子设备的数据传输速率(即网络速率)要求较低。因此，当电子设备处于游戏场景中，可确定电子设备处于低网速运行中。
3、电子设备处于亮屏状态，且电子设备所需传输的数据包的大小小于或等于第一预设阈值。
在亮屏状态下，为满足低网速应用场景，电子设备除了从数据传输速率这一维度考虑外，还可从电子设备所需传输的数据量(即所需传输的数据包的大小)进行考虑。其中，电子设备所需传输数据包的大小具体可指应用中电子设备所需传输的所有数据包的大小(即所需传输的数据量)，或者指单位时间内电子设备所需传输的数据包的大小。
具体地，在电子设备处于亮屏状态下，若电子设备所需传输的数据包的大小较大，例如大于第一预设大小阈值，则电子设备可认为当前自身的通信负载较大，即所需传输的数据包或数据量较大，用网需求较高，相应地电子设备可认为自身处于高网速应用场景。反之，若电子设备所需传输的数据包的大小较小，则电子设备可认为自身的通信负载较小，即所需传输的数据包或数据量较小，用网需求不高，相应地电子设备可认为自身此时处于低网速应用场景。
4、电子设备的设备温度大于或等于预设温度阈值。
无论在电子设备处于亮屏状态还是灭屏状态，当电子设备的设备温度过高，例如设备温度大于或等于预设温度阈值时，容易导致死机、断网，严重可以烧毁电子设备，具体可烧毁电子设备的应用处理器、基带处理器等器件。为降低整机温度、保护设备自身，电子 设备需自动关闭正在运行的应用，例如首先关闭功耗较高、网速要求较高的应用，如视频应用等，其次关闭功耗较低、网速要求较低的应用等，如天气应用、日历应用等。因此，当电子设备检测到自身整机温度过高，可认为电子设LRRC备当前已关闭网速要求较高的应用，即关闭电子设备中的高网速应用，此时电子设备处于低网速应用场景。
其中，电子设备的设备温度的检测方式并不做限定，例如当电子设备中安装有温度感应器时，可通过温度感应器检测并查看电子设备的设备温度或电子设备的上某个器件(例如应用处理器或基带处理器等)的温度。
在实际应用中，电子设备的设备温度是指整个电子设备中所有部件各自运行时的温度的总和，由于每个部件的温度获取均存在一定的误差，这样将导致电子设备的设备温度获取同样存在较大地误差，其获取的准确度或精确度较低。因此在实际应用中，电子设备的设备温度通可以电子设备中一些核心部件的温度替代，例如应用处理器(AP)的温度、片上系统芯片(system on chip，SOC)温度、电池温度等等。
例如，应用处理器(AP)作为电子设备的整机性能的最重要的硬件，其性能表现直接影响电子设备整机的性能，因此，应用处理器的温度将作为设备温度的一个重要体现温度。以设备温度为应用处理器的温度为例，电子设备可进入自身的输入输出系统(basic input output system，BIOS)中获取应用处理器的温度；或者，电子设备可运行应用处理器的温度获取软件(例如Python脚本文件等)，以获取应用处理器的温度。便于后续基于该应用处理器的温度来识别电子设备所处的应用场景为高网速应用场景还是低网速应用场景，这里不再赘述。
5、电子设备处于灭屏状态，且低网速运行，即电子设备的数据传输速率小于或等于第二预设速率。
灭屏状态下，电子设备处于低网速运行的场景有多种，可以有如下两种。
第一种，灭屏状态下，电子设备支持后台应用的运行，例如播放音乐等。为满足低网速的用网需求，电子设备可以进行如下应用的功能设置：允许低网速应用运行或禁止高网速应用运行，即开启低网速应用运行的功能或关闭高网速应用运行的功能。可理解地，在关闭电子设备中高网速应用运行的功能后，电子设备中只允许低网速应用运行。由于这些低网速应用中允许的数据传输速率较小，此时电子设备可确定电子设备处于低网速运行中，电子设备处于低网速应用场景。可选地，当电子设备中同时运行多个低网速应用时，它们的数据传输速率总和也比较小，例如小于第二预设速率，同样可满足低网速用网需求，此时仍确定电子设备处于低网速运行中。
第二种，当电子设备处于灭屏状态时，电子设备通常没有数据收发，或者仅保持必要的保证应用程序处于唤醒状态的数据包，例如心跳测试包或者监听数据包等，通常这一类型的数据包是周期性的收发并且数据包的大小也比较小。在上述情况下，可以视为电子设备对网络参数等要求较低，用网需求较低，认为电子设备处于低网速运行，即处于低网速应用场景。
可选地，在电子设备灭屏后，其数据传输速率通常会变得比较缓慢，例如数据传输速 率小于预设速率。因此在不考虑低网速应用场景识别准确度的情况下，当电子设备检测到自身处于灭屏状态时，可直接认为电子设备处于低网速应用场景。
6、电子设备处于灭屏状态，且电子设备所需传输的数据包的大小小于或等于第二预设阈值。
灭屏状态下，电子设备同样存在数据的收发，例如电子设备灭屏下载数据、灭屏传输心跳包等。为满足低网速的用网需求，电子设备除了考虑数据传输速率外，还可从UE所需传输的数据量(即所需传输的数据包的大小)这一维度进行识别。
具体地，在电子设备处于灭屏状态下，为满足低网速应用场景的低用网需求，可检测电子设备所需传输的数据包的大小来确定电子设备是否处于低网速应用场景。具体的当电子设备所需传输的数据包的大小小于第二预设大小阈值，则电子设备可认为自身的通信负载较大，用网需求较高，确定电子设备不处于低网速应用场景。反之，认为电子设备的通信负载较小，用网需求较低，确定电子设备处于低网速应用场景。
举例来说，以低网速应用场景为交互心跳包的应用场景为例。在电子设备无需进行业务通信时，为了维持电子设备和网络侧间的通信连接，通常采用心跳包机制来实现电子设备和网络侧之间连接的维护。具体地，电子设备可周期性地向网络侧发送心跳包，以通知电子设备当前与网络侧存在通信连接，以保持电子设备和网络侧之间的长连接。相应地，网络侧接收该心跳包后，同样可向电子设备返回响应包，以通知网络侧获知电子设备与网络侧存在通信连接。在实际应用中，该心跳包的大小很小，通常为几kb，也可为空包(即不携带任何业务数据，仅携带包头的数据包)等。在该场景下，电子设备显然处于低网速应用场景。
7、电子设备关闭5G网络通信功能。
电子设备可以响应于接收到用户的输入操作，关闭5G网络通信功能。在该场景下，电子设备根据用户的需求，确定出无需使用5G网络。在该场景下，电子设备处于低网速应用场景。

当电子设备上报给网络侧设备的UE辅助信息中overheating字段该上行辅载波数(reducedCCsUL)子信元的值为a时，a大于等于0。网络侧设备可以根据为电子设备激活a条上行辅载波。电子设备可以在该激活的a条上行辅载波上的物理上行共享信道(physical uplink shared channel，PUSCH)发送数据，以及发送上行参考信号。电子设备可以在其他未被激活的上行辅载波上的物理上行共享信道(physical uplink shared channel，PUSCH)不 发送数据，不发送上行参考信号。
需要说明的是，该overheating字段可以是基于第三代合作伙伴计划(the 3rd generation partner project，3GPP)R14或R15协议版本的，但不限于3GPP R14或R15协议版本，还可以是基于其他版本协议的。在一些协议版本中，overheating字段可以只包括最大辅载波数(reducedMaxCCs)信元，最大辅载波数(reducedMaxCCs)信元可以包括下行辅载波数(reducedCCsDL)子信元和上行辅载波数(reducedCCsUL)子信元。在一些协议版本中，overheating字段还可以包括其他信元。
