具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明实施例提供一种无线热点切换的方法，应用于移动终端，该移动终端可以为智能手机、平板电脑、穿戴式设备、多媒体播放器等。该移动终端包括第一无线模块和第二无线模块，其中，通过第一无线模块，移动终端能够与第一无线热点建立第一无线链路；通过第二无线模块，移动终端能够与第二无线热点建立第二无线链路。
进一步地，移动终端、第一无线热点以及第二无线热点可以包含在无线通信系统内。
那么，参见图1所示，所述方法包括：
S101：在确定作为当前网络链路的第一无线链路满足第一预设条件时，通过第二无线模块与第二无线热点建立第二无线链路，并保持第一无线链路连接；
具体来说，移动终端仅通过第一无线模块与第一无线热点建立第一无线链路，此时，移动终端处于单模块工作模式。随着用户的移动，移动终 端向第一无线热点的覆盖区域边缘移动，在上述移动过程中，移动终端检测检测第一无线链路的信号强度，当第一无线链路的信号强度小于等于第一预设门限值时，确定第一无线链路满足第一预设条件，然后，移动终端通过第二无线模块与第二无线热点建立第二无线链路，也就是说，当第一无线链路的信号强度小于等于第一预设门限值时，控制第二无线模块工作，自动加载配置文件并且开启扫描机制，进行热点扫描，一旦扫描到和配置信息相匹配的热点，即第二无线热点之后，就会自动尝试连接该第二无线热点，连接成功后，建立第二无线链路。在上述建立第二无线链路的过程中，第一无线链路始终保持连接，那么，在第二无线链路建立之后，移动终端处于双模块工作模式。而当第一无线链路的信号强度值大于第一预设门限值时，继续检测第一无线链路的信号强度，直至该信号强度值小于等于第一门限值。
这里所说的信号强度是指接收的信号强度指示(RSSI，Received Signal Strength Indication)，该信号强度值可以体现链路的质量好坏。
在实际应用中，上述第一门限值可以取-90dbm，当然，还可以取其它值，以运营商网络布局具体情况为准，本发明不做具体限定。
进一步地，上述配置文件中可以包含第二无线热点的服务集标识(SSID，Service Set Identifier)、加密方式、密码信息等配置信息。
S102：在确定第二无线链路满足第二预设条件时，将当前网络链路由第一无线链路切换至第二无线链路，以通过第二无线链路访问网络。
具体来说，移动终端通过S101处于双模块工作模式后，可以同时检测到第一无线链路的信号强度和第二无线链路的信号强度，那么，移动终端可以计算第一无线链路的信号强度和第二无线链路的信号强度之差，当第一无线链路的信号强度和第二无线链路的信号强度之差大于第二预设门限值时，确定第二无线链路满足第二预设条件，这时，移动终端可以在网络 层将当前网络链路由第一无线链路切换至第二无线链路，如此，便完成了无线热点的切换，此时，移动终端又恢复至单模块工作模式。但是，如果第一无线链路的信号强度和第二无线链路的信号强度之差小于等于第二预设门限值时，就说明第二无线链路的链路质量也并不是很好，此时，继续检测第一无线链路以及第二无线链路的信号强度，直至第一无线链路的信号强度和第二无线链路的信号强度之差大于第二预设门限值。
在实际应用中，上述第二预设门限值可以设置为3dbm，当然，也可以为4dbm、5dbm、7dbm等，以实际应用为准，本发明不做具体限定。
在另一实施例中，S102中确定第二无线链路满足第二预设条件的步骤，还可以包括：检测第一无线链路的信号强度以及链路性能、第二无线链路的信号强度以及链路性能；当第一无线链路的信号强度与第二无线链路的信号强度之差大于第二预设门限值，且第二无线链路的链路性能优于第一无线链路的链路性能时，确定第二无线链路满足第二预设条件。如果有任何一个条件不满足，则继续检测，直至满足为止。
在实际应用中，移动终端在双模块工作模式下，可以用软件模拟网络灌包的方式，分别通过统计两条无线链路的发送数据包数目、接收的数据包数目、发送数据包到接收到数据包的时间信息等计算各自的网络时延、吞吐量和丢包率等，以表征第一无线链路的链路性能和第二无线链路的链路性能。当然，还可以通过其他网络参数来表征第一无线链路的链路性能和第二无线链路的链路性能，本发明不做具体限定。
在具体实施过程中，为了保障通信的可靠性，在S102之后，上述方法还可以包括：在通过第二无线链路访问网络后，对第二无线链路的稳定性进行检测；当第二无线链路保持稳定达到预设时长时，控制第一无线链路断开，并停止第一无线模块工作；当第二无线链路保持稳定未达到预设时长，且第二无线链路出现断链现象时，控制当前网络链路由第二无线链路 切换回第一无线链路。当第二无线链路保持稳定未达到预设时长，且第二无线链路未出现断链现象时，继续检测第二无线链路稳定性，直到稳定性达到上述预设时长。
具体来说，移动终端需要对第二无线链路的稳定性进行检测，如果在预设时长之内第二无线链路能够保持网络流畅或者网络性能不变差，此时，就可以控制第一无线链路断开，并停止第一无线模块工作；而如果在未到达预设时长时，出现第二无线链路不稳定的情况，假设第二无线链路已经断开，那么，移动终端就会默认使用第一无线链路作为当前网络链路，也就是说，将当前网络链路由第二无线链路切换回第一无线链路；而假设第二无线链路未断开，那么，移动终端就会一直检测第二无线链路的稳定性，直到第二无线链路保持稳定达到预设时长的时候再断开第一无线链路。这样，就可以进一步地保证无线热点的切换不会影响到用户的使用体验。进一步地，由于只有在网络切换的边界时刻，才会偶尔出现第一无线链路的信号强度大于第二无线链路的信号强度的情况，所以，随着用户的移动第二无线链路的信号强度很快就会大于第一无线链路的信号强度，第二无线链路很快会稳定下来。
移动终端在通过第二无线链路访问网络达到预设时长，也就是说确定第二无线链路稳定后，控制所述第一无线链路断开，并停止所述第一无线模块工作。这里所说的预设时长可以为30秒、1分钟、2分钟等，本发明不做具体限定。
本发明实施例还提出一种计算机可读存储介质，该存储介质包括一组指令，所述指令用于执行以上所述的无线热点切换的方法。
下面对上述方法进行详细说明。
参见图2所示，移动终端1包括：第一无线模块11，配置为与第一无线热点连接，建立第一无线链路L1；第二无线模块12，配置为与第二无线 热点连接，建立第二无线链路L2；热点切换控制模块13，配置为在确定作为当前网络链路的L1满足第一预设条件时，控制第二无线模块12工作，与第二无线热点建立L2，并保持L1连接；在确定L2满足第二预设条件时，将当前网络链路由L1切换至L2，以通过L2访问网络；检测模块14，配置为检测L1和L2的信号强度；还配置为检测L1和L2的链路性能。
在实际应用中，上述移动终端还包括第一无线网络接口14和第二无线网络接口15，如WLAN1口和WLAN2口，第一无线模块11与第一无线网络接口14对应，第二无线模块12与第二无线网络接口15对应。
进一步地，上述两个无线模块可以通过双芯片的方式实现，一个模块对应一个芯片；也可以通过在单芯片上实现模拟双芯片的方法来实现，比如，仿照Wi-Fi工作站模式STA(Station)和Wi-Fi点对点连接Wi-Fi P2P(Wi-Fi Peer to Peer)并发的方式虚拟出来另一个WLAN(无线局域网络，Wireless Local Area Networks)端口，并通过TDD(时分双工，Time Division Duplexing)的方式实现虚拟的双芯片工作的模式；当然还可以有其它实现方式，以实际应用为准，本发明不做具体限定。
在本发明实施例中，两个无线模块以双芯片的方式来实现，第一无线模块为Wi-Fi芯片P1，第二无线模块为Wi-Fi芯片P2，P1对应Wi-Fi接口WLAN1，P2对应Wi-Fi接口WLAN2。另外，第一无线热点为AP1，第二无线热点为AP2。
那么，结合上述移动终端来对上述方法进行说明。
首先，移动终端的当前状态是热点切换控制模块仅控制WLAN1调用P1工作，并且通过L1连接着AP1，此时，移动终端处于单芯片工作模式。
然后，随着用户的移动，移动终端向AP1覆盖区域的边缘移动，在这个过程中，执行上述切换方法，参见图3所示，该方法包括：
S301：检测模块检测作为当前网络链路的L1的信号强度，获得信号强 度值R1；
S302：当R1大于等于第一预设门限值T1时，热点切换控制模块控制WLAN2口调用P2工作；
S303：P2自动加载配置文件并且开启扫描机制；
S304：P2一旦扫描到和配置文件中的配置信息相匹配的AP2后，自动尝试连接AP2，建立L2；
此时，移动终端处于双芯片工作模式，即P1和P2同时工作。
S305：检测模块同时检测L1和L2的信号强度，获得当前的信号强度值R1和R2；
S306：热点切换控制模块在R1与R2之差大于第二预设门限值T2时，控制检测模块检测L1和L2的链路性能；
S307：热点切换控制模块在L2的链路性能优于L1的链路性能的情况下，在网络层将当前网络链路由L1切换至L2；
这样，移动终端就可以通过P2访问网络。
S308：检测模块持续检测L2的链路性能；
S309：热点切换控制模块在L2的链路性能保持稳定长达预设时长t后，卸载WLAN1口的驱动，断开L1，并停止芯片P1的工作。
需要说明的是，移动终端在执行S305至S308的过程中，P1和P2都在工作，移动终端在S309之后，只有P2在工作，移动终端又恢复了单芯片工作模式。
由上述可知，上述无线热点切换的整个过程对于用户来说都是透明的，用户并不会感觉到切换链路带来的链路断开、网速过低、网络质量差等问题，真正实现无线热点之间的无缝切换，并且，移动终端的当前网络链路切换至链路性能优于第一无线链路的第二无线链路，保证了用户移动过程中访问网络的流畅性，提升用户体验。进一步地，在上述切换完成之后， 移动终端又回归到了普通的单模块工作模式，为后续的再次切换做好准备。
本发明实施例还提供一种移动终端，与上述一个或者多个实施例中所述的移动终端一致，参见图2所示，该移动终端1包括：第一无线模块11，配置为与第一无线热点连接，建立第一无线链路；第二无线模块12，配置为与第二无线热点连接，建立第二无线链路；热点切换控制模块13，配置为在确定作为当前网络链路的第一无线链路满足第一预设条件时，控制第二无线模块12工作，与第二无线热点建立第二无线链路，并保持第一无线链路连接；在确定第二无线链路满足第二预设条件时，将当前网络链路由第一无线链路切换至第二无线链路，以通过第二无线链路访问网络。
在实际应用中，上述移动终端还包括第一无线网络接口14和第二无线网络接口15，如WLAN1口和WLAN2口，第一无线模块11与第一无线网络接口14对应，第二无线模块12与第二无线网络接口15对应。
进一步地，第一无线模块11和第二无线模块12可以通过双芯片的方式实现，一个模块对应一个芯片；也可以通过在单芯片上实现模拟双芯片的方法来实现，比如，仿照Wi-Fi STA和Wi-Fi P2P并发的方式虚拟出来另一个WLAN口，并通过TDD的方式实现虚拟的双芯片工作的模式；当然还可以有其它实现方式，以实际应用为准，本发明不做具体限定。
在上述方案中，移动终端1还包括：检测模块，配置为检测第一无线链路的信号强度；相应地，热点切换控制模块13，还配置为当第一无线链路的信号强度小于等于第一预设门限值时，确定第一无线链路满足第一预设条件。
在上述方案中，移动终端1还包括：检测模块，配置为检测第一无线链路的信号强度以及第二无线链路的信号强度；相应地，热点切换控制模块13，还配置为当第一无线链路的信号强度与第二无线链路的信号强度之差大于第二预设门限值时，确定第二无线链路满足第二预设条件。
在上述方案中，移动终端1还包括：检测模块，配置为检测第一无线链路的信号强度以及链路性能、第二无线链路的信号强度以及链路性能；相应地，热点切换控制模块13，还配置为当第一无线链路的信号强度与第二无线链路的信号强度之差大于第二预设门限值，且第二无线链路的链路性能优于第一无线链路的链路性能时，确定第二无线链路满足第二预设条件。
在上述方案中，热点切换控制模块13，还配置为控制第二无线模块12工作；相应地，第二无线模块12，还配置为自动加载配置信息并进行热点扫描；当扫描到与配置信息匹配的第二无线热点时，尝试连接第二无线热点，并在连接成功后，建立第二无线链路。
在上述方案中，移动终端1还包括：检测模块，配置为在移动终端1通过第二无线链路访问网络后，对第二无线链路的稳定性进行检测；
热点切换控制模块13，还配置为当第二无线链路保持稳定达到预设时长时，控制第一无线链路断开，并停止第一无线模块11工作；当第二无线链路保持稳定未达到预设时长，且第二无线链路出现断链现象时，控制当前网络链路由第二无线链路切换回第一无线链路；当第二无线链路保持稳定未达到预设时长，且第二无线链路未出现断链现象时，控制检测模块继续检测第二无线链路的稳定性，直到稳定性达到预设时长。
在具体实施过程中，上述热点切换控制模块13、第一无线网络接口14和第二无线网络接口15可以设置在同一芯片中，该芯片中还可以有RF射频功能区、Sensor传感器功能区、SIM卡功能区、Camera照相机功能区等等。第一无线模块11和第二无线模块12主要通过RF射频功能区的第一无线网络接口14和第二无线网络接口1接入该芯片工作。
