Description

一种通信系统的切换方法和终端设备 技术领域
本申请涉及终端技术领域，尤其涉及一种通信系统的切换方法和终端设备。
背景技术
随着无线通信技术的发展，越来越多的通信制式被广泛应用到各终端设备。支持多通信制式的终端设备，是指具有多个无线通信模块的终端设备，其每个无线通信模块可以通过收发无线信号实现数据的传输功能，并且每个通信模块所使用的通信制式可以不同。比如，通信制式可以是蜂窝移动通信技术例如GSM、CDMA、LTE等，也可以是无线局域网通信技术例如Wi-Fi。总之，支持多通信制式的终端设备，具有通过不同的通信制式传输业务数据的能力。
现实环境中，存在多个各自支持的不同通信制式的通信系统共存的场景。因此，终端设备需要从多个通信系统中选择一个通信系统，并与该通信系统建立连接。
现有技术中，终端设备选择通信系统的过程如下：
以三个通信系统为例，每个通信系统支持的通信制式不同。假设终端设备当前与通信系统一的接入节点AP1连接，终端设备可以检测AP1的Qos取值。当终端设备确定当前连接的AP1的Qos取值低于阈值门限时，中断与AP1的连接，与AP2连接，以检测AP2的Qos取值。若AP2的Qos取值高于该阈值门限，终端设备就较长时间与AP2建立连接。
由此可见，现有技术中，终端设备切换通信系统的过程中，只有在当前连接的通信系统的Qos取值低于阈值门限时，才寻找Qos取值高于所述阈值门限的其它通信系统。可见，现有技术中，通信系统的切换条件单一，无法满足终端设备智能化需求。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
本申请实施例涉及的通信制式，即网络类型，例如蜂窝移动通信网络或无线局域网通信。蜂窝移动通信网络例如GSM制式、CDMA制式、LTE制式等；无线局域网通信网络例如WiFi 5GHz制式WiFi 2.4GHz制式。
本申请实施例涉及的通信系统特指无线通信系统，例如、无线接入点(例如路由器)或者基站，不同的通信系统可以支持不同的通信制式。比如，基站支持蜂窝移动通信网络例如GSM制式、CDMA制式、LTE制式等，无线接入点支持无线局域网通信网络例如WiFi 5GHz制式WiFi 2.4GHz制式等。
本申请实施例涉及的Qos参数，可以用于指示通信系统的网络质量。Qos参数可以包括时延Latency(是指做出触发动作与得到响应之间的时间间隔)、抖动jitter、丢包率(Loss Rat io，英文简称：LR)是衡量分组交换(英文全称：Packet Switching，英文简称： PS)传输质量的核心指标，丢包率越高，PS传输质量越差，对业务的损伤越严重，甚至业务不可用。、吞吐量throughput(单位时间传输到特定目的地的有用信息的数目(以bit为单位))等多种类型的参数。一个通信系统的Qos参数的大小与该通信系统的接入量相关。比如，当通信系统的接入量较大时，该通信系统的Qos参数会降低。
本申请实施例涉及的信号强度参数，可以用于指示通信系统的信号强度。不同的通信系统，信号强度参数不同。比如，通信系统是无线接入点时，信号强度参数可以是接收信号的强度指示(Received Signal Strength Indicator，RSSI)。通信系统是蜂窝通信系统时，信号强度参数可以是参考信号接收功率(Reference Signal Receiving Power，RSRP)或者参考信号接收质量(Reference Signal Receiving Quality，RSRQ)等。
需要说明的是，前述的Qos参数与信号强度参数不同。举例来说，终端设备可以同时检测附近的多个通信系统的信号强度参数，但是终端设备只能检测当前连接的通信系统的Qos参数。若终端设备要检测其它通信系统的Qos参数，需要与当前连接的通信系统断开连接，并与其它通信系统建立连接，然后检测其它通信系统的Qos参数。
另外，一个通信系统的信号强度较大时，该通信系统的Qos参数不一定较大。因此，通信系统的信号强度较大时，若该通信系统的接入量较大，那该通信系统的Qos参数也较小。
以下介绍终端设备、用于这样的终端设备的图形用户界面(graphical user interface，GUI)、和用于使用这样的终端设备的实施例。在本申请一些实施例中，终端设备可以是包含诸如个人数字助理和/或音乐播放器等功能的便携式终端设备，诸如手机、平板电脑、具备无线通讯功能的可穿戴设备(如智能手表)等。便携式终端设备的示例性实施例包括但不限于搭载

或者其它操作系统的便携式终端设备。上述便携式终端设备也可以是其它便携式终端设备，诸如具有触敏表面(例如触控面板)的膝上型计算机(laptop)等。还应当理解的是，在本申请其他一些实施例中，上述终端设备也可以不是便携式终端设备，而是具有触敏表面(例如触控面板)的台式计算机。以下以终端设备是手机为例进行说明。
通常情况下，终端设备支持多种应用。比如以下应用中的一个或多个：绘图应用、演示应用、字处理应用、游戏应用、电话应用、视频播放器应用、音乐播放器应用、电子邮件应用、即时消息收发应用、照片管理应用、相机应用、浏览器应用、日历应用、时钟应用、支付应用和健康管理应用等。其中，即时消息收发应用可以有多种。比如短信应用、彩信应用、各种邮箱应用、微信、腾讯聊天软件(QQ)、WhatsApp Messenger、连我(Line)、照片分享(instagram)、Kakao Talk、钉钉等。用户通过即时消息收发应用，可以将文字、语音、图片、视频文件以及其他各种文件等信息发送给其他联系人。

因此，本申请实施例提供一种通信系统的切换方法，该方法可以适用于图1所示的手机100或者其它能够进行通信业务的电子设备中。以手机100为例，该方法中，手机100中可以事先检测各个通信系统的Qos取值，存储以便使用。比如，手机100中存储有地理位置信息和通信系统的Qos取值的对应关系，或者，存储有通信系统的信号强度和Qos取值的对应关系(这两个对应关系中还可以包括其它参数比如时间信息、用户习惯、当前应 用等，以便手机100根据这些参数选择最合适的通信系统，具体将在后文介绍)。或者手机100从其他设备处获取各个通信系统的QoS取值，例如通过有线或无线通信协议，主动或被动的从其他电子设备处获取。这样的话，手机100可以根据地理位置或者信号强度，确定各个通信系统的Qos取值，然后手机100选择能够更好的满足当前业务需求的通信系统(具体过程将在后文介绍)，并与该通信系统连接。因此，本申请实施例提供的通信系统的切换方法中，由于手机100事先知晓各个通信系统的Qos取值，所以手机100可以在不中断当前连接的通信系统的基础上，知道哪个通信系统的Qos取值能够更好的满足当前业务需求，手机100直接切换到该通信系统即可，无需中断当前连接的通信系统，与其它通信系统建立连接之后再检测其它通信系统的Qos取值是否能够满足当前业务需求，对当前运行业务的影响较小。
需要说明的是，如前述内容可知，各个通信系统的Qos取值是动态变化的(比如一个通信系统的接入量较大时，该通信系统的Qos取值降低)。因此，手机100可以实时的检测(更新)各个通信系统的Qos取值，即学习前述的两个对应关系。
方式一：手机100可以自动学习，得到前述的两个对应关系。
示例性的，手机100在第一次使用(比如激活)时，启动学习；或者，手机100可以周期性的启动学习；或者，手机100检测到自身位置移动时启动学习；或者，手机100在每次开机时启动学习；或者，手机100在检测到用户当前未操作手机时启动学习；或者，手机100可以在预设时间段内(手机100出厂时设置好的，或者是用户自定义的)启动学习。
可选的，手机100在学习前述的两个对应关系的过程中，可以综合考虑上述的多种情况的至少一种情况。比如，手机100检测到自身位置移动，且用户当前未操作手机100时，启动学习。由于手机100检测各个通信系统的Qos取值需要分别于每个通信系统建立连接，才能检测各个通信系统的Qos取值，所以手机100可以在不同的位置处，且处于“空闲”(尽可能不影响当前业务的情况下)时，自动与各个通信系统连接以检测各个通信系统的Qos取值。
方式二，用户主动触发手机100学习得到前述的两个对应关系。
举例来说，手机100上可以设置一入口，该入口用于触发手机100学习得到前述两个对应关系。该入口(比如图标)可以设置在手机100的任何界面中，比如锁屏界面、主界面、应用程序的显示界面中。用户可以根据自己的需求主动触发手机100学习得到前述两个对应关系。
前述介绍了手机100可以被动或者主动获得两个对应关系。下面介绍手机100得到这两个对应关系的具体过程。因为涉及到两个对应关系，下文先介绍地理位置和通信系统的Qos取值的对应关系，然后介绍信号强度和通信系统的Qos取值的对应关系。
手机100获取地理位置信息和各个通信系统的Qos取值的对应关系的过程如下：
请参见图2所示，为本申请实施例提供的一种应用场景的示意图。如图2所示，该应用场景中包括三个通信系统，分别对应AP1、AP2、LTE基站(三个通信系统分别支持不同的通信制式)。手机在位置A处检测三个通信系统各自的Qos参数，得到位置A处的Qos参数集合1。Qos参数集合1包括在位置A处AP1、AP2、LTE基站各自的Qos参数。
具体而言，手机100在位置A处检测各个通信系统的Qos参数时，可以分别与不同的Qos参数对应的通信系统建立连接，以检测各个通信系统的Qos参数。比如，手机100在 位置A处，先与AP1连接，检测AP1的Qos参数，然后中断与AP1的连接，与AP2连接，检测AP2的Qos参数。
同样的，手机在位置B和位置C处分别检测这三个通信系统的Qos参数，得到位置B处的Qos参数集合2和位置C处的Qos参数集3。手机存储位置A、位置B、位置C以及Qos参数集合1-3，以便使用。
假设手机检测到当前所处的位置比如位置D，若位置D与位置A之间的距离小于预设距离，手机100根据预设策略在Qos参数集合1中确定合适的Qos参数，并与该Qos参数对应的通信系统连接。其中，预设策略可以是手机100选择Qos参数集合1中取值最大的Qos参数，或者，根据手机100根据当前运行的应用的Qos需求在Qos参数集合1中选择合适的Qos参数(比如，手机100在Qos参数集合1中选择Qos取值大于当前运行应用的Qos需求的通信系统)；或者，手机100根据用户习惯在Qos参数集合1中选择合适的Qos参数；或者，手机100根据价格在Qos参数集合1中选择合适的Qos参数(比如，手机100当前运行应用需要消耗的流量较大时，手机100在Qos参数集合1中选择AP1或AP2，而不选择LTE)等。具体内容，将在后文介绍。
请参见图3所示，为本申请实施例提供的通信系统的切换方法的流程示意图。该方法可以适用于前述图1所示的手机或其它电子设备中。在下文的介绍中，以手机100为例进行说明，且以图2所示的应用场景为例。如图3所示，该方法的流程包括：
S301：手机100获取多个Qos参数集合，其中每个Qos参数集合对应一个位置。例如通过在一个位置处检测多个通信系统的Qos参数，得到Qos参数集合，移动位置进而得到多个Qos参数集合，其中每个Qos参数集合对应一个位置。
在本申请实施例中，Qos参数可以包括时延、抖动、丢包率、吞吐量等多种类型的参数，下文的介绍中，以Qos参数是吞吐量为例。
请继续参见图2所示，手机100在位置A处检测到3个通信系统各自的Qos参数比如吞吐量(比如，手机100在位置A处，先与AP1连接，检测AP1的Qos参数，然后中断与AP1的连接，与AP2连接，检测AP2的Qos参数，然后中断与AP2的连接，与LTE连接，检测LTE的Qos参数)。假设手机100检测到AP1的吞吐量为90GB、AP2的吞吐量70GB、基站的吞吐量为90GB，即手机100得到位置A处的Qos参数集合1(90GB、70GB、90GB)。同样的，手机100可以得到位置B处的Qos参数集合2，且得到位置C处的Qos参数集合3。得请参见表1，示出了位置信息与Qos参数集合之间的映射关系。
表1
Figure PCTCN2018112219-appb-000002
需要说明的是，表1中的各个通信系统的Qos取值可以是手机100事先检测好的(比如手机100在当前时间之前，已分别与不同的Qos参数对应的通信系统建立连接，检测各个通信系统的Qos参数)。因此，假设手机100当前与AP1连接，若手机100需要从AP1切换到其它通信系统，无需中断与AP1的连接，然后与其它通信系统建立连接以检测其它 通信系统的Qos参数，只需要根据表1中记录的其它通信系统的Qos取值，确定与哪个通信系统建立连接即可。其中，表1只是一种示例，并不是对位置信息与Qos参数集合之间的映射关系的限定，且表1中的位置A、位置B或位置C可以是地理坐标信息，如经纬度，也可以是地理位置信息，如行政区域、街道、门牌号码等；另外，表1中还可以包含采集时间信息，采集时运行的应用的信息等。
S302：手机100检测当前所处的地理位置。
示例性的，同步骤S301中确定位置的方法，手机100可以通过GPS、基站，WiFi热点，蓝牙(iBacon)，辅助GPS(assisted GPS，AGPS)等一种或多种方法定位。
S303：手机100根据当前所处的地理位置，从所述多个Qos参数集合中确定与所述地理位置对应的Qos参数集合，所述Qos参数集合包括多个通信系统的Qos参数。
作为一种示例，请继续参见图2所示，假设用户手机检测到当前的地理位置在位置D。手机100在表1中查询是否存在位置D，若存在，则根据表1确定与位置D对应的Qos参数集合即可。若手机100在表1中未查询到位置D，则手机100确定位置A、位置B或者位置C中哪个位置距离位置D最近。假设位置A距离位置D最近，则手机100确定与位置D对应的Qos参数集合即为Qos参数集合1。
手机100根据Qos参数集合1，确定哪个通信系统的Qos参数取值最大，就与Qos参数取值最大的通信系统连接。比如，Qos参数集合1(90GB、70GB、70GB)指示AP1的Qos参数取值最大，则手机100与AP1连接。
前述的表1只是一种举例，实际上，手机100在检测各个通信系统的Qos参数时，可以还考虑其它因素。下面分别列举几种示例。
示例一：由于不同时间段，每个通信系统的Qos参数的取值可能不同。以AP1为例，在晚上10:00-12:00期间，AP1接入量较大，导致AP1的Qos参数的取值较低；而在早上上6:00-8:00期间，AP1接入量较小，导致AP1的Qos参数的取值较高。
因此，手机100可以在检测一个位置处各个通信系统的Qos参数时，考虑时间信息。即手机100可以统计一个位置处在每个时间段各个通信系统的Qos参数。以图2所示的应用场景为例，表2示出了每个位置处在不同时间段各个通信系统的Qos取值。
表2
Figure PCTCN2018112219-appb-000003
举例来说，假设用户手机检测到当前的地理位置是位置D当前时间是13：00。手机100在表2中查询是否存在位置D以及当前时间13：00，并在表2中查询与位置D对应的位置和时间段，若存在，则确定与所述位置及时间段都对应的Qos参数集合即可。若手机100在表2中未查询到位置D，或者未查询到包含当前时间的时间段，则手机100确定位置A、位置B或者位置C中哪个位置距离位置D最近以及确定与当前时间最接近的时间段。假设位置A距离位置D最近，且与当前时间最接近的时间段是10:00-12:00，则确定 与位置D和当前时间13：00对应的Qos参数集合即为Qos参数集合1.1。
示例二，用户可能会根据自身需求手动选择与某个通信系统建立连接。手机100可以记录用户的操作。表3示出了位置信息与Qos参数集合的又一种示例。
表3
Figure PCTCN2018112219-appb-000004
举例来说，手机10检测到当前处于位置A，手机100根据表3确定用户选择的通信系统是AP2，则手机与AP2建立连接。
在本申请实施例中，上述的表1、表2或表3可以是用户自定义的，也可以是手机自学习的。当然表3同样可以包含时间信息以及处于运行中的应用的信息。以便电子设备做更加复杂和精准的匹配。
在本申请实施例中，上述的表1、表2或表3可以更新。以表1为例，电子设备更新表1的方式可以有多种。更新上述各个表的更新条件可以在电子设备出厂时预设在设备中，也可以允许用户进行设置和变更。
方式一：手机可以以一定周期自动更新表1。
如前述内容，手机100需要断开当前连接的通信系统，与其它通信系统建立连接，才能检测其它通信系统的Qos参数。若手机断开与当前通信系统的连接，可能会导致手机当前运行业务出现卡顿。因此，手机100可以在预设时间段内周期性的自动更新表1，其中，预设时间段可以是手机100自学习确定的，也可以是用户设置的。比如，用户设置手机于每天晚上2:00更新表1。再比如，手机100可以在用户当前未操作手机的情况下更新表1(比如，用户当前未操作手机时，手机100可以断开当前连接的通信系统，与其它通信系统建立连接，以检测其它通信系统的Qos参数)。再比如，手机100还可以按照预设条件自动更新表1，即每次当手机100与某个通信系统建立连接(可能是用户手动连接)后，手机100检测到通信系统的Qos参数，然后更新表1。
方式二：用户手动更新表1。
示例性的，手机上可以设置一个入口(比如开关控件或者特定手势，也可以是语音指令，特定指纹等等)，当手机检测到该入口，如开关控件被触发时，更新表1。比如，该开关控件可以设置在手机中的某个app(比如设置app)中。
方式三：手机100在确定到需要更新对应关系表时进行更新，例如确定表1不准确的情况下，更新表1，例如检测到用户做出新的选择，例如检测到移动到新的位置，例如检测到有可连接的新通信系统等。
举例来说，手机100检测到当前处于位置A，根据表1确定与位置A对应的Qos参数集1，并根据该Qos参数集1确定与AP1连接。当手机100与AP1连接之后，手机100检测AP1的Qos参数，若检测到的Qos参数集合小于存储的Qos参数集1中AP1的Qos参数，说明存储的AP1的Qos参数不准确，手机100可以更新表1。
S304：手机100根据预设策略从确定出的Qos参数集合中选择合适的Qos参数，并与 该Qos参数对应的通信系统建立连接。
其中，手机100根据预设策略从确定出的Qos参数集合中选择合适的Qos参数有多种实现方式。方式一，手机100确定出Qos参数集合后，可以确定Qos参数集合中Qos参数取值最大的通信系统。方式二，手机100可以确定Qos参数集合中能够满足当前运行的应用程序的QoS需求的通信系统，比如手机100选择Qos取值大于当前运行的应用程序需求的通信系统。方式三，手机100根据用户习惯选择合适的通信系统。举例来说，用户在使用手机100观看电影时，经常手动将手机100与AP1连接，那么手机100检测当前播放电影时，自动切换到与AP1连接。
可选的，除了上述三种方式外，手机100还可以考虑其它条件。比如，手机100根据使用当前应用的时长，或用户切换当前应用的可能性等信息，选择合适的通信系统。举例来说，手机100检测到用户打开一个对QoS要求很高的应用程序，但检测到该应用程序的使用时长小于预设时长比如小于2分钟，然后就退出该应用程序，此时手机100可无需切换通信系统。或者，手机100检测到用户只使用了该应用程序中的一个对QoS要求不高的功能，此时，手机100可以无需选择Qos取值很大的通信系统，只选择Qos取值大于等于该功能的Qos需求的通信系统即可。比如，用户使用手机100中的微信应用时，若仅仅使用微信中的聊天(文字或图片的发送)时，手机100可以选择Qos(比如时延)取值相对较小的通信系统，若使用微信应用中的视频/语音通话时，手机100可以选择Qos(比如时延)取值相对较高的通信系统。手机100还可以结合各个通信系统的费用，用户的使用习惯等进行选择，例如用户在观看视频，但根据手机100(其他APP记录的)记录的用户的历史使用习惯/作息习惯可知用户只会看几分钟就会关闭，则只选择费用低的能保证当前视频需求的通信系统连接即可，而不切换到费用高的其他能提供更高观看体验的通信系统。
下面以方式二为例，介绍手机100选择通信系统的过程。
示例性的，手机100中存储有应用程序与Qos需求的映射关系。表4示出了应用程序与Qos需求(以吞吐量为例)之间的映射关系的一种示例。其中，表4中每个应用程序的Qos需求可以是每个应用程序上架时定义好的，或者是用户自定义的。
表4
应用程序 Qos需求
微信 30GB
电话 50GB
爱艺奇 80GB
举例来说，手机100当前正运行爱艺奇，根据表4确定爱艺奇的Qos需求是80GB。假设手机当前处于位置A，手机根据表1确定与位置A对应的Qos参数集合是Qos参数集合1。手机100确定Qos参数集合1中Qos参数取值大于80GB的通信系统，即AP1。手机100与AP1建立连接。
再例如，手机100当前正运行微信，根据表4确定微信的Qos需求是30GB。假设手机当前处于位置A，手机根据表3确定与位置A对应的Qos参数集合是Qos参数集合1。手机100确定Qos参数集合1中Qos参数取值大于30GB的通信系统有两个，即AP1和AP2。手机100可以根据用户选择，与AP2建立连接。
需要说明的是，上述的举例中(表1-表4中)仅是以Qos参数是吞吐量为例的，实际 上Qos参数还可以是时延、抖动、丢包率或错包率等，即表1-4中的QoS参数可以是这些参数中的一个或多个。
通常，不同的应用程序对时延、吞吐量、丢包率等要求不同。比如，对时延或抖动要求较高、对丢包率或错包率要求不高的流类业务(Streaming Class)和语音业务。其中，流类业务，比如音频或者视频播放业务(比如手机100中的音乐/视频播放应用、教育、健身类应用等)。语音业务，比如电路交换载体上的话音业务(例如GSM的话音业务)。再比如，IP电话和视频电话(比如手机100中的IP电话/视频电话类应用等)。对于这些应用，手机100可以选择时延或抖动满足其需求的通信系统(比如，选择时延大于该应用的时延需求的通信系统)。
举例来说，假设手机100当前运行音频播放应用，手机100根据地理位置和Qos参数集(时延)的对应关系，确定与当前的地理位置对应的Qos参数集，然后在该Qos参数集中确定时延大于音乐播放时延需求的通信系统，并与该通信系统连接。
再比如，对时延或抖动要求较低，但是对丢包率的较为要求很高的交互类业务和背景类业务。其中，交互类业务，比如终端设备(比如，手机100、人或其它机器)和远程设备(比如远程服务器)进行在线数据交互的业务，比如，Web浏览、数据库检索、网络游戏等(比如手机100中的工具/字典/购物/聊天/游戏类应用等)。其中，背景类业务，比如后台E-mail接收、SMS或者接收一些文件和数据库下载(比如手机100中的E-mail类应用等)。对于这些应用，手机100可以选择丢包率满足其需求的通信系统(比如，选择丢包率小于该应用的丢包率需求的通信系统)。
举例来说，假设手机100当前运行网络游戏，手机100根据地理位置和Qos参数(丢包率)的对应关系，确定与当前的地理位置对应的Qos参数集，然后在该Qos参数集中确定丢包率小于网络游戏的丢包率需求的通信系统，并与该通信系统连接。
通过以上举例可知，手机100可以有多种方式选择通信系统。在实际应用中，手机100可以采用上述几种方式中的一种或多种，或者除去上述几种方式之外的其它方式来选择通信系统。
需要说明的是，图3所示的实施例中的全部步骤或者部分步骤(比如S302-S305)可以一直执行。比如，只要手机100处于开机状态，就一直执行S302-S305。
当然，图3所示的实施例中的全部步骤或者部分步骤(比如S302-S305)也可以只在满足条件时执行。比如，当手机100检测到当前位置发生变化时，执行一次图2所示的全部或部分步骤(比如S302-S305)。再比如，当手机100检测到当前连接的通信系统的Qos不满足当前业务需求/用户需求，或者当前功耗较高(大于预设功耗)时，再执行图3所示的全部或部分步骤(比如S302-S305)。在这种方式，可以避免频繁切换，而且有助于节约计算量，降低功耗。
在上面的实施例中，介绍了手机从多个通信系统中确定一个合适的通信系统的几种方式，在这几种方式中，均需要知道手机当前所处的位置。下面介绍另一实施例，在该实施例中手机无需知道手机当前所处的位置，也可以确定从多个通信系统中确定出合适的通信系统。
请参见图4所示，为本申请实施例提供的一种应用场景的示意图。如图4所示，该应用场景中包括三个通信系统，分别对应AP1、AP2、LTE基站(三个通信系统分别支持不同的通信制式)。手机100某个位置处检测三个通信系统各自的信号强度参数，得到该位 置处的信号强度参数集1。同样的，手机在其它两个位置处分别检测这三个通信系统的信号强度参数，得到两个信号强度参数集，即信号强度参数集2和信号强度参数集3。手机存储信号强度参数集合1-3，以便使用。
可选的，手机100可以在检测每个通信系统的信号强度时，检测该通信系统的Qos取值。比如手机100检测当前连接的AP1的信号强度和Qos取值，然后中断与AP1的连接，与AP2连接，以检测AP2的信号强度和Qos取值。或者，由于手机100检测各个通信系统的信号强度时，无需与各个通信系统建立连接，比如可以检测通信系统的广播信息即可检测该通信系统的信号强度。因此，手机100可以检测各个通信系统的信号强度和检测各个通信系统的Qos取值可以是两个独立的过程。比如手机100在某个位置处检测到所有通信系统的信号强度，得到信号强度集之后，再检测各个通信系统的Qos取值。举例来说，手机100先检测AP1、AP2和LTE的信号强度，得到信号强度集。然后手机100与AP1连接，检测AP1的Qos参数，然后中断与AP1的连接，与AP2连接，检测AP2的Qos参数，然后中断与AP2的连接，与LTE连接，检测LTE的Qos参数，得到Qos参数集。手机100得到信号强度集和Qos参数集之后，可以建立信号强度集和Qos参数集的对应关系(下文介绍)，存储以便使用。
假设手机100检测到各个通信系统当前的信号强度，得到一个信号强度参数集4。手机可以从存储的信号强度参数集1-3中寻找与信号强度参数集4相匹配的信号强度参数集。假设手机100经匹配，确定信号强度参数集1与信号强度参数集4匹配，那么手机100根据信号强度参数集1和前述的信号强度集和Qos参数集的对应关系，确定与强度参数集1对应的Qos参数集，然后在该Qos参数集中，根据预设策略选择通信系统，并与该通信系统连接。
其中，预设策略前面已经描述过，为了说明书的简洁，在此不重复赘述。
这个实施例(图4所示的实施例)与上一个实施例(图3所示实施例)不同，上一个实施例中，手机100检测地理位置信息，根据地理位置信息，确定Qos参数集，进而确定合适的通信系统。在这个实施例中，手机100无需检测地理位置信息，而是根据检测到的信号强度集确定Qos参数集，进而确定合适的通信系统。当然，手机100可以选择上一个实施例或者这个实施例的方案实现通信系统的切换，即这两个实施例的方案可以独立应用；或者，当手机100可以获得地理位置时，采用上一个实施例的方案，当无法获得地理位置时，启用这个实施例的方案。
图5示出了本申请实施例提供的另一种通信系统的切换方法的流程图。该方法可以适用于图1所示的手机100或其他终端设备中。下文以手机100为例，且以图4所示的应用场景为例。如图5所示，该方法的流程包括：
S501：手机100在多个位置处检测多个通信系统中每个通信系统的信号强度参数，得到每个位置对应的信号强度参数集，进而得到多个信号强度参数集。
在本申请实施例中，手机100可以在每次启动时检测多个通信系统的信号强度参数集；或者，手机可以周期性的检测多个通信系统的信号强度参数集；或者，手机可以在用户主动触发时，检测多个通信系统的信号强度参数集。由于无需与一个通信系统建立连接即可检测该通信系统的信号强度，检测多个通信系统的信号强度参数的动作可以在多种情况下进行，例如用户手动触发，或者在设备满足预设条件(例如闲时，按固定周期，在检测到位置变化，用户切换应用程序等)时自动进行等等。其中，信号强度参数可以有多种，比 如通信系统是无线接入点时，信号强度参数可以是接收信号的强度指示(Received Signal Strength Indicator，RSSI)。通信系统是蜂窝通信系统时，信号强度参数可以是参考信号接收功率(Reference Signal Receiving Power，RSRP)或者参考信号接收质量(Reference Signal Receiving Quality，RSRQ)等。
其中，手机100在每个位置处检测的多个通信系统可以是位于手机预设距离的范围内的通信系统；或者，是手机曾经连接过的多个通信系统；或者是手机100能够检测到的所有通信系统。
请继续参见图4所示，手机100检测到3个信号强度参数集。每个信号强度参数集包括三个通信系统的信号强度。以信号强度参数集1为例，信号强度参数集1包括AP1、AP2、基站各自的信号强度参数，其中，AP1的RSSI为80db，AP2的RSSI为70db；LTE的RSRP为85db，信号强度参数集1为(80db、70db、85db)。请参见表5，表5示出了信号强度参数集1的示例。其中Qos参数可以包含时延、抖动、丢包率、吞吐量等多种类型的参数中的一个或多个，本实施例中Qos参数以吞吐量为例，其他情况不再赘述。
表5
Figure PCTCN2018112219-appb-000005
如前述内容可知，信号强度参数和Qos参数不同，所以表5中还可以包括Qos参数集1(手机100检测AP1、AP2和LTE的Qos参数的过程在前面介绍过，不重复赘述)，Qos参数集1中包括每个通信系统的Qos参数。
同样的，手机可以其它采集信号强度参数集，比如信号强度参数集2和信号强度参数集3。以信号强度参数集2为例，比如表6示出了信号强度参数集2的示例。
表6
Figure PCTCN2018112219-appb-000006
通过以上描述可知，手机100中可以存储信号强度参数集1-3，以及每个信号强度参数集对应的Qos参数集合。因此，手机100无需检测地理位置，只需要根据当前信号强度参数来进行通信系统的质量评估，并在确定需要切换时直接切换到预先确定好的目标系统，能减少切换系统的用时，减小对业务的影响，提高切换效率以及设备的智能性。具体的，请参见表7，为信号强度参数集与Qos参数集之间的映射关系的一种示例。
表7
信号强度参数集 信号强度参数取值 Qos参数集
信号强度参数集1 (80db、70db、70db) (90GB、70GB、30GB)
信号强度参数集2 (70db、60db、75db) (50GB、20GB、60GB)
信号强度参数集3 (90db、80db、80db) (30GB、50GB、60GB)
S502：手机100根据当前采集的第一信号强度参数集，确定与所述第一信号强度参数集匹配的第二信号强度参数集。
用户在使用手机100的过程中，比如，手机100启动一个应用时，可以采集到第一信号强度参数集。手机100根据第一信号强度参数集在表7中的信号强度参数集1-3进行匹配，确定出一个与第一信号强度参数集相匹配的信号强度参数集。下面介绍手机100将第一信号参数集与存储的信号强度参数集1-3进行匹配的过程。
请继续参见图4所示，假设手机100采集到的第一信号强度参数集为信号强度参数集4(75db、70db、80db)。手机100确定信号强度参数集4与存储的信号强度参数集1-3中哪个信号强度参数集“距离”最近。这里的两个信号强度参数集之间的“距离”，可以理解为，两个信号强度参数集中相对应的两个信号强度之间的差值最小。具体而言，手机100可以确定信号强度参数集4中AP1的信号强度与信号强度参数集1中AP1的信号强度之间的第一差值，确定信号强度参数集4中AP2的信号强度与信号强度参数集1中AP2的信号强度的第二差值，确定信号强度参数集4中LTE的信号强度与信号强度参数集1中LTE的信号强度的第三差值，手机100将第一差值、第二差值、第三差值相加，得到第一和，该第一和即信号强度参数集4与信号强度参数集1之间的“距离”。同样的，手机100可以确定信号强度参数集4与信号强度参数集2之间的“距离”，以及信号强度参数集4与信号强度参数集3之间的“距离”。手机100可以确定“距离”信号强度参数集4最近的信号强度参数集。
S503：手机根据确定出的第二信号强度参数集，确定与所述第二信号强度参数集对应的Qos参数集合。
假设手机100确定与信号强度参数集4“距离”最近的信号强度参数集是信号强度参数集1即第二信号强度集。手机100可以根据表5确定与信号强度参数集1对应的Qos参数集，即Qos参数集1。手机100根据Qos参数集1确定合适的通信系统，并与该通信系统建立连接。
作为一种示例，如前述内容可知，由于不同时间段每个通信系统的Qos取值可能不同。因此，手机100可以在采集每个位置处各个通信系统的Qos参数时，考虑时间信息。请继续参见图4所示，手机100在检测各个通信系统的Qos参数时，还可以记录时间信息，即手机100在哪一个时间段内检测各个通信系统的Qos参数，具体请参见表8所示，为信号强度参数集1在不同时间段下的Qos参数集。
表8
Figure PCTCN2018112219-appb-000007
举例来说，请继续参见图4所示，假设手机100采集到的第一信号强度参数集为信号强度参数集4(75db、70db、80db)。手机100确定与信号强度集4“距离”最近的是信号强度集1，且确定当前时间在10：00-12：00的时间段内。因此，手机100确定Qos参数集为(90GB、70GB、30GB)。手机100确定Qos取值最大的通信系统，即Qos取值为90GB的通信系统即AP1，手机100与AP1建立连接。
作为另一种示例，用户可能会根据自身需求手动选择与某个通信系统建立连接。手机100可以记录用户的操作。请参见表9，示出了另一种信号强度参数集1在不同时间段下的Qos参数集之间的映射关系。

举例来说，请继续参见图4所示，假设手机100采集到的第一信号强度参数集为信号强度参数集4(75db、70db、80db)。手机100确定与信号强度集4“距离”最近的是信号强度集1，且确定当前时间在10：00-12：00的时间段内。因此，手机100根据用户选择确定与AP1建立连接。可选的，映射关系中还可以包括采集时手机中运行的应用程序，包括前台和/或后台应用程序；还可以包括这些应用程序的属性，例如语音业务，视频业务，游戏业务等，也可以是时延敏感业务，丢包率敏感业务，吞吐量敏感业务之类。
S504：手机100根据预设策略从确定出的Qos参数集合中选择合适的通信系统，并与确定出的通信系统连接。
可选的，手机100确定Qos参数集合后，可以确定该Qos参数集合中Qos参数取值最大的通信系统，并与该通信系统连接；或者，手机100根据当前运行的应用程序的Qos需求，确定该Qos参数集合中满足该Qos需求的通信系统，并与该通信系统建立连接；或者根据用户选择确定合适的通信系统，并与该通信系统连接；或者，手机100从满足当前运行的应用程序的Qos需求的多个通信系统中选择资费最低的并与之建立连接。在实际应用中，手机100可以根据上述方式以及用户设置的其他方式中的一种或者多种方式来选择合适的通信系统。
在前述的实施例中，是以手机100采集到3个信号强度参数集为例的。在实际应用中，由于手机100在不同的位置处采集的各个通信系统的信号强度会有差异，即手机100在不同位置处，得到的信号强度参数集有差异。因此，手机100可以将每个信号强度参数集都存储下来，然后通过图5所示的方法选择合适的通信系统。下面介绍另一实施例，在该实施例中，手机100采集的信号强度参数集较多时，可以将信号强度参数集归类，从被归为一类的多个信号强度参数集中选择一个信号强度参数集作为类信号强度参数集，以该类信号强度集来反映所述被归为一类的多个信号强度集，即一类信号强度参数集对应一个类信号强度参数集。手机无需存储多个信号强度参数集，只需存储类信号强度参数集即可，有助于节省内存。
需要说明的是，图5所示的实施例中的全部步骤或者部分步骤(比如S502-S505)可以一直执行。比如，只要手机100处于开机状态，就一直执行S302-S305。
当然，图5所示的实施例中的全部步骤或者部分步骤(比如S502-S505)也可以只在满足条件时执行。比如，当手机100检测到当前位置发生变化时，执行一次图5所示的全部或部分步骤(比如S502-S505)。再比如，当手机100检测到当前连接的通信系统的Qos不满足当前业务需求/用户需求、或者当前功耗较高(大于预设功耗)时，再执行图5所示的全部或部分步骤(比如S502-S505)。在这种方式，可以避免频繁切换，而且有助于节约计算量，降低功耗。
请参见图6所示，为本申请实施例提供的一种应用场景的示意图。如图6所示，手机100采集了12个信号强度参数集(图6中的12个黑点)。手机100将这12个信号强度参数集分类，得到3类信号强度参数集。示例性的，手机100将信号强度参数集1-4归类为第一类信号强度参数集，将信号强度参数集5-8归类为第二类信号强度参数集，将信号强度参数集9-12归类为第三类信号强度参数集。
下面介绍手机100将12个信号强度参数集分类的过程。
示例性的，手机100确定信号强度参数集1-4中任意两个信号强度参数集之间的“距离”小于第一预设距离，则手机100将信号强度参数集1-4归为一类。手机100确定信号强度参数集5-8中任意两个信号强度参数集之间的“距离”小于第二预设距离，则手机100将信号强度参数集5-8归为一类。手机100确定信号强度参数集9-12中任意两个信号强度参数集之间的“距离”小于第三预设距离，则手机100将信号强度参数集9-12归为一类。
手机100将信号强度参数集1-4归类为第一类信号强度参数集后，可以从信号强度参数集1-4中选择一个信号强度参数集作以代表第一类信号强度参数集，被选择出的信号强度参数集被称为类信号强度参数集1。手机100只需存储类信号强度参数集1即可，无需存储强度参数集1-4，节省资源。比如，手机100可以从信号强度参数集1-4中随机选择一个信号强度参数集，或者，手机100取信号强度参数集1-4的平均值，得到一个信号强度参数集。同样的，手机100可以确定代表第二类信号强度参数集的类信号强度参数集2，确定第三类信号强度参数集的类信号强度参数集3。手机100将确定的3个类信号强度参数集存储下来，以便使用。后续手机100使用这个3个类信号强度参数集的过程，和前述过程类似，不多赘述。
举例来说，请参见图7，以一个房屋的室内户型图为例。该房屋内设置有4个无线通信系统。这4个无线通信系统分别为：WIFI AP1、WIFI AP2、LTE、UMTS。这4个无线通信系统分别位于房屋内的不同位置。
手机100可以在每个位置处采集这4个通信系统中每个通信系统的信号强度参数，得到信号强度参数集，进而得到多个信号强度参数集，每个位置对应一个信号强度参数集，如图7中的黑点。由于得到的信号强度参数集即黑点较多，手机100可以确定多个信号强度参数集归类。
具体而言，假设手机100室内总共采集到1000个信号强度参数集，即1000个黑点。手机100对这1000个信号强度参数集进行归类。具体过程为：手机100从这1000个信号强度参数集中确定有300个信号强度参数集之间的“距离”小于预设距离，则手机100将这300个信号强度参数集归为第一类信号强度参数集。手机100从这300信号强度参数集中选择一个信号强度参数集以代表第一类信号强度参数集，选择出的信号强度参数集即为 类信号强度参数集1。该第一类信号强度参数集即手机100在客厅检测到的多个信号强度参数集。
同样的，手机100从这1000个信号强度参数集中确定有200个信号强度参数集之间的“距离”。手机100将这200个信号强度参数集归为第二类信号强度参数集，并从这2000个信号强度参数集中选择一个信号强度参数集以代表第二类信号强度参数集，选择出的信号强度参数集即为类信号强度参数集2。该第二类信号强度参数集即手机100在卧室检测的到的多个信号强度参数集。其它类的信号强度参数集的归类过程类似，不多赘述。
如图7所示，手机100得到5类信号强度参数集，每一类信号强度参数集对应一个类信号强度参数集，而且每个类信号强度参数集对应一个Qos参数集。
下面继续以图7为例，介绍手机100通信系统之间的切换过程。
假设用户在客厅操作手机100。手机100采集到第一信号强度参数集。手机100确定该第一信号强度参数集属于5类中的哪一类信号强度参数集。具体而言，手机100可以判断第一信号强度参数集与哪一个类信号强度参数集之间的“距离”小于预设距离。若第一信号强度参数集与类信号强度参数集1之间的“距离”小于预设距离，则手机100确定第一信号强度参数集属于第一类信号强度参数集。手机100根据类信号强度参数集1，确定与所述类信号强度参数集1对应的Qos参数集1。假设手机100确定的Qos参数集1指示AP1的Qos参数取值最大，则手机100与AP1建立连接；或者手机100确定当前运行的应用程序是微信，根据表3确定微信的Qos需求，手机100根据Qos参数集1确定Qos取值大于微信的Qos需求的通信系统，并与该通信系统建立连接。
当用户携带手机100从客厅移步到卧室的过程中，手机100检测到当前的位置发生变化，手机100可以再次采集到第二信号强度参数集。手机100再次确定该第二信号强度参数集属于5类中的哪一类信号强度参数集。手机100确定第二信号强度参数集属于第二类信号强度参数集，则手机100根据第二类信号强度参数集的类信号强度参数集2，确定与该类信号强度参数集2对应的Qos参数集2。手机100根据该Qos参数集2，确定一个通信系统，并将该通信系统建立连接。
在上述举例中，手机100采集第一信号强度参数集后，当检测到当前的位置发生变化时，再次采集第二信号强度参数集；或者，手机100可以在采集到第一信号强度参数集后，经过预设时长，再次采集第二信号强度参数集；或者，手机100在采集到第一信号强度参数集后，在用户主动触发下，再次采集第二信号强度参数集；或者，手机100采集到第一信号强度参数集后，若当前运行的应用程序由第一应用程序切换为第二应用程序，则手机100再次采集第二信号强度参数集。
需要说明的是，如前述内容可知，通信系统的Qos参数可能随着时间、接入点的变化而变化，而且，通信系统的信号强度参数也会随着时间、通信系统的地理位置(比如AP的位置移动)的变化而变化。因此，手机100可以更新信号强度参数集和Qos参数集之间的映射关系。手机100可以只更新信号强度参数集和Qos参数集之间的映射关系中的信号强度参数，也可以只更新Qos参数集。
需要说明的是，信号强度参数的采集所消耗的功耗开销较小，而QoS参数的检测的所消耗的功耗开销较大。因此，手机100可以设置信号强度参数的更新周期和Qos参数集的更新周期不同。比如，强度参数的更新周期设置的较短，Qos参数集的更新周期设置的较长。下面介绍手机100根据更新信号强度参数集和Qos参数集之间的映射关系中的QoS 参数集的过程。
请参见图8所示，为本申请实施例提供的更新信号强度参数集和Qos参数集之间的映射关系的过程的示意图。如图8所示，所述方法的流程包括：
S801：手机100更新信号强度参数集和Qos参数集之间的映射关系。
在本申请实施例中，手机100可以有多种触发原因来触发更新信号强度参数集和Qos参数集之间的映射关系。方式一，用户主动触发更新。方式二，手机100周期性的自动更新；方式三，当手机100根据原信号强度参数集和Qos参数集之间的映射关系确定出的Qos参数集不准确时，手机100根据更新信号强度参数集和Qos参数集之间的映射关系。
以方式三为例，在S801之前，所述方法的流程还包括：
S800a：手机100切换到目标通信系统。
手机100根据前述的图3或图5所示的流程，确定合适的通信系统之后，便于该通信系统连接，该通信系统即目标通信系统。如前述内容可知，一个通信系统的Qos参数取值可能受到接入量或其他因素的影响，所以当手机100与目标通信系统连接之后，目标通信系统的Qos参数取值可能并不如预期。因此，手机100切换到目标通信系统后，可以检测目标通信系统的Qos参数。若手机100检测目标通信系统的Qos参数取值小于存储的该目标通信系统的Qos参数取值，则手机100可以触发更新信号强度参数集和Qos参数集之间的映射关系。
S800b：手机100检测到用户手动将目标通信系统切换成其它通信系统。
如前述内容可知，手机100切换到目标通信系统之后，目标通信系统的Qos参数取值可能并不如预期。比如，手机100检测目标通信系统的Qos参数取值小于存储的该目标通信系统的Qos参数取值，导致手机100运行业务出现卡顿或时延，这种情况下，用户也可能手动切换到其他通信系统。
手机100可以统计切换到目标通信系统后，用户手动将目标通信系统切换成其它通信系统的次数。若次数较多，说明手机100中存储的目标通信系统的Qos参数取值不准确，手机100可以更新信号强度参数集和Qos参数集之间的映射关系。
S800c：手机100判断用户手动将目标通信系统切换成其它通信系统的次数是否大于预设次数，若是，则执行S801；若否，则执行S800a。
以方式二为例，在S801之前，所述方法的流程还包括：
S800d：手机100确定类信号强度参数集到期。
示例性的，手机100在建立信号强度参数集和Qos参数集之间的映射关系时，可以为该映射关系中每个Qos参数集设置有效期。以表5为例，手机100可以设置Qos参数集1的有效期为24小时。当手机100检测到Qos参数集1的有效期到期时，手机100更新信号强度参数集和Qos参数集之间的映射关系。当然，手机100可以只更新Qos参数集1，也可以更新所有的Qos参数集。
以方式三为例，在S801之前，所述方法的流程还包括：
S800e：手机100检测到用户主动触发更新信号强度参数集和Qos参数集之间的映射关系的操作。
示例性的，手机100中可以设置一开关控件。当该开关控件被触发时，手机100更新信号强度参数集和Qos参数集之间的映射关系。所述开关控件可以是设置于某一个app(比如设置app)中。
需要说明的是，手机100自身通信参数的设置不同，会影响到检测到的Qos参数取值。(比如，手机100检测通信系统的Qos参数时，将手机100的通信参数上报通信系统，通信系统基于这种通信参数向手机100反馈报文，报文用于指示手机100与通信系统之间的链路的Qos参数)。其中，通信参数可以是手机100中的天线(比如图1中的天线2)的配置参数。比如，手机100的天线2是单输入单输出模式(single-input single-output，SISO)还是多输入多输出模式(multiple-input multiple-output，MIMO)；或者手机100当前支持的是载波(component carrier，CC)个数。然而，手机100的通信参数的设置决定了手机100的功耗。
在本申请实施例中，手机100确定合适的通信系统后，与该通信系统建立连接。手机100可以在满足当前所需求的Qos参数取值的基础上，尽可能的降低手机100的功耗。
作为一种示例，手机100可以设置多个功耗档位，以及每个档位对应的不同的通信参数配置、功耗开销、Qos参数取值。示例性的，请参见表9，为本申请实施例提供的功耗档位与通信参数之间的映射关系的一种示例。
表9
功耗档位 MIMO配置 CA配置 功耗 Qos参数取值
0 SISO 1CC 1000w 30GB
1 2*2MIMO 1CC 1010w 40GB
2 4*4MIMO 1CC 1020w 50GB
3 SISO 2CC 1030w 80GB
4 2*2MIMO 2CC 1040w 90GB
5 4*4MIMO 2CC 1050w 100GB
举例来说，手机100当前正运行爱艺奇，根据表4确定爱艺奇的Qos需求是80GB。假设手机当前处于位置A，手机根据表1确定与位置A对应的Qos参数集合是Qos参数集合1。手机100确定Qos参数集合1中Qos参数取值大于80GB的通信系统，即AP1。为了尽可能的降低手机100的功耗。手机100可以设置能够保证Qos参数取值为80GB的功耗档位，即档位3即可。此时，手机100将天线配置为SISO模式，且CA配置为2CC。
再例如，手机100根据当前运行的应用程序确定一个通信系统后，手机100可以检测该应用程序是否在后台运行。若该应用程序在后台运行(比如，手机100处于锁屏状态，但后台下载任务在下载)，手机100可以采用低功耗档位。若该应用程序在前台运行，手机100采用不低于该应用程序需求的Qos参数取值的最低功耗档位。比如，爱艺奇在后台运行，手机100可以将功耗档位调整为档位1，爱艺奇在前台运行时，手机100可以将功耗档位调整为档位3(爱艺奇的Qos需求是80GB)。
示例性的，表9可以是手机100根据自学习得到的，也可以是用户自定义的，或者设计人员根据经验确定的。表9可以周期性的自动更新；或者在用户主动触发更新时更新。
如前述内容可知，手机100可以更新信号强度参数集和Qos参数集之间的映射关系。为了尽可能的准确的检测各个通信系统的Qos参数取值，手机100可以在更新信号强度参数集和Qos参数集之间的映射关系时，设置为最高或较高档位，以保证Qos参数的检测的准确性。
本申请的各个实施方式可以任意进行组合，以实现不同的技术效果。
上述本申请提供的实施例中，从客户端作为执行主体的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，客户端可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
需要说明的是，本申请实施例提供的通信系统的切换功能(比如图3中的全部步骤或者部分步骤比如仅有S302-S304；或者图5中的全部步骤或者部分步骤比如仅有S502-S504)可以在手机100开机时就一直启动，也可以是用户主动触发时才启动。
作为一种示例，请参见9中的(a)所示，手机100当前在进行视频通话，在视频通话界面中设置一图标901。当图标901被触发时，手机100根据图3或者图5所示的方案(比如，手机100可以执行图2或图5的全部步骤；再比如，手机100在当前时间之前已经获取到地理位置和Qos参数集的对应关系时，可以只执行图3中的S302-S304；或者，手机100在当前时间之前已经获取到信号强度集和Qos参数集的对应关系时，可以只执行图5中的S502-S504)，确定符合当前业务需求的Qos取值，手机100切换到该Qos取值对应的通信系统。
可选的，手机100切换到其它通信系统后，可以输出提示，以提示用户已切换到最优的通信系统。比如请继续参见图9中的(b)所示，手机100检测到图标901被触发后，显示提示信息902，提示信息902提示用户已切换到HUAWEI-53C0。
在这种方式中，当用户初次使用锁屏上的图标901时，可以通过提示信息902帮助用户学习该图标901的作用，减轻用户对手机100的学习负担，方便用户操作。
在图9中是以手机100的视频通话界面上设置入口(图标)为例的，实际上，手机100的解锁界面，或者，在其它界面(比如主界面、电影播放界面)中也可以设置一入口。比如手机100显示主界面，该主界面中添加一图标(可以以图标的形式显示，也可以以悬浮球或其它形式显示)。
作为另一种示例，请参见图10，手机100显示电影播放的界面1001，在该界面1001中显示提示信息，即“检测到更优的通信系统，是否断开当前连接，并切换到XX通信系统”，或者“当前网络质量不佳，是否切换到XX网络”等。若用户选择“是”1002，则手机100断开当前连接的通信系统，并切换到更优的通信系统。若用户选择“否”1003，则手机100不切换系统，保持与当前的通信系统连接。
在这种方式中，用户可以自己决定是否切换通信系统。比如，手机100当前连接的是Wifi，手机100播放电影。若该Wifi的接入量较大，导致手机100电影播放出现卡顿，手机100提示用户是否切换到4G。出于节省费用的角度，用户可以选择“否”，即手机100继续与该Wifi连接。
