Description

WiFi漫游方法、装置、移动终端及存储介质 技术领域
本申请涉及通信技术领域，具体涉及一种WiFi漫游方法、装置、移动终端及存储介质。
背景技术

移动终端工作在双WiFi模式时，会同时连接两个不同的WiFi网络，若这两个WiFi网络在同一频段(即同为2.4G或5G)，则两个不同的WiFi网络需要分时工作，会导致单个WiFi网络延迟变大、网速不稳定、网络传输性能较差。

下面对本申请实施例进行详细介绍。
请参阅图1，图1是本申请实施例公开的一种基于双WiFi模块的WiFi漫游方法的流程示意图，如图1所示，该基于双WiFi模块的WiFi漫游方法包括如下步骤。
101，在第一WiFi模块和第二WiFi模块均处于连接状态的情况下，移动终端控制第一WiFi模块连接的接入点AP工作的频段为第一频段，控制第二WiFi模块连接的AP工作的频段为第二频段，第一频段与第二频段没有重叠。
本申请实施例中，无线保真(WIreless-Fidelity，WiFi)，也可以称为wifi、Wi-Fi，是一种无线连接方式。移动终端可以包括双WiFi模块。双WiFi模块可以包括第一WiFi模块(也可以称为第一WiFi通信模块)和第二WiFi模块(也可以称为第二WiFi通信模块)，可以支持两个WiFi频段的信号的同时收发，保证两个WiFi频段的信号互不干扰。
双WiFi模块可以同时连接两个接入点(access point，AP)，比如，第一WiFi模块连接第一AP，第二WiFi模块连接第二AP。双WiFi模块可以同时支持两个WiFi通路的数据收发，比如双WiFi模块可以同时支持第一WiFi通路和第二WiFi通路的数据收发，其中，第一WiFi通路是移动终端和无线网络之间建立的通过第一WiFi模块、第一AP连接的数据通路。第二WiFi通路是移动终端和无线网络之间建立的通过第二WiFi模块、第二AP连接的数据通路。
第一WiFi模块和第二WiFi模块均可以支持的多个频段，比如，第一WiFi模块支持2.4G(Hz)频段和5G(Hz)频段，第二WiFi模块也支持2.4G(Hz)频段和5G(Hz)频段。
本申请的第一WiFi模块和第二WiFi模块均处于Station模式(简称STA模式)，第一WiFi模块和第二WiFi模块需要接入WiFi热点来接入WiFi网络。WiFi热点，为AP的一种。AP可以为无线AP。
双WiFi模式是两个WiFi模块同时收发数据的模式，在双WiFi模式下，第一WiFi模块和第二WiFi模块可以同时工作。与双WiFi模式对应的是单WiFi模式，单WiFi模式是仅有一个WiFi模块工作的模式，只能同时支持一个WiFi频段的信号的收发。本申请实施例的双WiFi模块具有双频双发(dual band dual concurrent，DBDC)功能或双频并发(dual-band simultaneous，DBS)功能，支持2×2天线，2组天线都配套有放大电路和功放芯片，可以支持天线同时发射和接收信号。
本申请实施例中，第一WiFi模块连接的接入点(access point，AP)的工作频段与第二WiFi模块连接的AP的工作频段不同。第一WiFi模块连接的接入点AP工作的频段为第一频段，第二WiFi模块连接的AP工作的频段为第二频段。比如，第一频段为2.4G频段，第二频段为5G频段，或者，第一频段为5G频段，第二频段为2.4G频段。由于第一WiFi模块和第二WiFi模块工作在不同的频段，第一WiFi模块与第二WiFi模块同时收发信号时并不会造成干扰，并且可以实现两路WiFi信号的同时收发，大大提高了WiFi网络的传输效率。
102，移动终端控制第一WiFi模块处于第一漫游限制模式，限制第一WiFi模块在第一频段内漫游。
本申请实施例中，WiFi漫游，指的是当网络环境存在多个AP时，由于每个AP的覆盖范围是有限的，存在至少两个AP的覆盖范围相互有一定范围的重合时，因为无线上网的流动性特点，持有移动终端的无线用户可以在这多个AP的整个覆盖区内移动，移动终端的无线网卡能够自动发现附近信号强度最大的AP，并从当前连接的AP切换到信号强度最大的AP来收发数据，这样移动终端就能连接到新的AP从而保持其原有的上网服务，保持不间断的网络连接。移动终端这样一个从当前连接的AP换到另一个AP并保持网络连接的过程，被称之为WiFi漫游。
一般而言，要做到WiFi漫游需要一些基本的配置，首先在结构上需要部署AP+接入控制器(access controller，AC)架构。其次，需要所有的个AP的服务集标识(Service Set Identifier，SSID)、认证方式、客户端配置与接入点网络中的配置完全相同，信道彼此没有干扰。要做到没有干扰，AP部署时相邻AP(相邻的AP指的是空间上相邻的覆盖范围有重叠的AP)间的信道不一样，并且在频率上不重叠交错，同时对部署AP无线覆盖重叠范围进行控制(比如，重叠范围可以控制在20％～30％之间)。例如，在2.4G频段，信道1、信道6、信道11是三条完全不重叠的信道；在5.8G频段，信道149、信道153、信道157、信道161、信道165是五条完全不重叠的信道。
具体的，请参见图2，图2是本申请实施例公开的一种相邻AP的信道选择示意图，如图2所示，图2以2.4G频段频段为例，在空间上部署有AP1、AP2、AP3等多个AP(为了便于说明，图2中仅示出了3个AP)，其中，AP1的覆盖范围为A1、AP2的覆盖范围为A2，AP3的覆盖范围为A3，A1与A2的重叠区域为a12，A2与A3的重叠区域为a23，其中，AP1信道为信道11、AP2的信道为信道1、AP3的信道为信道6。AP1与AP2相邻，AP2与AP3相邻。当持有移动终端的无线用户处于无重叠覆盖的A1区域(A1区域中除a12区域之外的区域)时，移动终端选择AP1进行连接。当持有移动终端的无线用户从无重叠覆盖的A1区域移动至a12区域时，移动终端选择AP1与AP2中信号强度最大的AP进行连接，如果移动终端选择了AP2进行连接，则移动终端实现了从AP1漫游到AP2的WiFi漫游(仍然在2.4G频段，只是信道不同而已)。当持有移动终端的无线用户从a12区域移动至无重叠覆盖的A2区域(A2区域中除a12区域和a23区域之外的区域)时，移动终端选择AP2进行连接。当持有移动终端的无线用户从无重叠覆盖的A2区域移动至a23区域 时，移动终端选择AP2与AP3中信号强度最大的AP进行连接，如果移动终端选择了AP3进行连接，则移动终端实现了从AP2漫游到AP3的WiFi漫游(仍然在2.4G频段，只是信道不同而已)。当移动终端从a23区域移动至无重叠覆盖的A3区域(A3区域中除a23区域之外的区域)时，则移动终端选择AP3进行连接。
在双WiFi模式下，如果第一WiFi模块和第二WiFi模块都可以进行WiFi漫游，当第一WiFi模块漫游的频段与第二WiFi模块漫游的频段相同，为了避免干扰，只能让其中的一个WiFi模块工作，从而降低了双WiFi模块的工作效率。
其中，第一漫游限制模式，是指允许在第一频段内进行漫游而不允许漫游到其他频段的漫游模式。
本申请实施例中，在双WiFi模块下，移动终端设置第一WiFi模块处于第一漫游限制模式，以限制第一WiFi模块只能第一频段内漫游，避免出现第一WiFi模块漫游到第二WiFi模块所连接的AP所处的第二频段以导致第一WiFi模块对第二WiFi模块的干扰的情况，从而提高双WiFi模块的网络传输性能。
请参阅图3，图3是本申请实施例公开的另一种基于双WiFi模块的WiFi漫游方法的流程示意图，如图3所示，该基于双WiFi模块的WiFi漫游方法包括如下步骤。
301，在第一WiFi模块和第二WiFi模块均处于连接状态的情况下，移动终端控制第一WiFi模块连接的接入点AP工作的频段为第一频段，控制第二WiFi模块连接的AP工作的频段为第二频段，第一频段与第二频段没有重叠。
302，移动终端控制第一WiFi模块处于第一漫游限制模式，限制第一WiFi模块在第一频段内漫游。
本申请实施例中的步骤301至步骤302的具体实施可以参见图2中的步骤201至步骤202，此处不再赘述。
303，移动终端控制第二WiFi模块处于第二漫游限制模式，限制第二WiFi模块在第二频段内漫游。
其中，步骤302和步骤303的执行顺序不做限定，步骤302和步骤303可以同时执行，也可以步骤302在步骤303之前执行，或者步骤302在步骤303之后执行。
其中，第二漫游限制模式，是指允许在第二频段内进行漫游而不允许漫游到其他频段的漫游模式。
本申请实施例中，移动终端控制第一WiFi模块处于第一漫游限制模式后，还可以控制 第二WiFi模块处于第二漫游限制模式，将两个WiFi模块都进入漫游限制模式，将两个WiFi模块分别限制在不同的频段内漫游，从而避免出现第一WiFi模块漫游到第二WiFi模块所连接的AP所处的第二频段，或第二WiFi模块漫游到第一WiFi模块所连接的AP所处的第一频段，以导致第一WiFi模块和第二WiFi模块相互干扰的情况。通过限制第一WiFi模块和第二WiFi模块的部分漫游功能，可以避免第一WiFi模块和第二WiFi模块由于漫游带来的干扰，从而提高双WiFi模块的网络传输性能。
可选的，图3所示的方法还可以包括如下步骤：
在第一WiFi模块处于断开状态，第二WiFi模块处于连接状态的情况下，若第二WiFi模块处于漫游限制模式，移动终端将第二WiFi模块从漫游限制模式切换至限制解除模式，取消第二WiFi模块的漫游频段限制。
漫游限制模式，是指允许在某一频段内进行漫游而不允许漫游到其他频段的漫游模式。漫游限制模式可以包括上述第一漫游限制模式或上述第二漫游限制模式。
限制解除模式是可以自由漫游的模式，可以漫游到任意频段。
其中，第一WiFi模块处于断开状态的原因有多种，比如，第一WiFi模块由于故障、供电等原因停止工作。又比如，由于第一WiFi模块原本被限制在第一频段内漫游，当移动终端附近没有可用的第一频段的AP时，则第一WiFi模块会被迫断开连接。
本申请实施例中，如果第一WiFi模块处于断开状态，只有第二WiFi模块处于连接状态的情况下，如果第二WiFi模块仍处于漫游限制模式，则移动终端可以将第二WiFi模块从漫游限制模式切换至限制解除模式，取消第二WiFi模块的漫游频段限制，允许第二WiFi模块在第一频段和第二频段之间漫游。比如，在第一WiFi模块处于断开状态，只有第二WiFi模块处于连接状态的情况下，允许第二WiFi模块在2.4G频段和5G频段之间漫游。
由于只有一个WiFi模块处于连接状态，并且该WiFi模块支持多个频段，则可以允许该WiFi模块在多个频段内漫游，从而提高单WiFi模块下的网络传输性能。
可选的，如果第一WiFi模块断开连接的原因是由于第一WiFi模块原本被限制在第一频段内漫游，当移动终端附近没有可用的第一频段的AP时而导致第一WiFi模块被迫断开连接。则移动终端会根据第一WiFi模块和第二WiFi模块在第二频段内的历史信号收发能力大小来决定采用哪个WiFi模块进行工作。移动终端附近没有可用的第一频段的AP，指的是移动终端不处于第一频段的AP的覆盖范围内，即移动终端无法搜索到的第一频段的AP。
可选的，如果第二WiFi模块断开连接的原因是由于第二WiFi模块原本被限制在第二频段内漫游，当移动终端附近没有可用的第二频段的AP时而导致第二WiFi模块被迫断开连接。则移动终端会根据第一WiFi模块和第二WiFi模块在第二频段内的历史信号收发能力大小来决定采用哪个WiFi模块进行工作。移动终端附近没有可用的第二而频段的AP，指的是移动终端不处于第二频段的AP的覆盖范围内，即移动终端无法搜索到的第二频段的AP。
具体的，如果移动终端附近没有可用的第一频段的AP，只有可用的第二频段的AP，移动终端会比较第一WiFi模块和第二WiFi模块在第二频段内的历史信号收发能力，选择在第二频段内的历史信号收发能力较高的WiFi模块在第二频段工作(选择在第二频段内的历史信号收发能力较高的WiFi模块与附近可搜索到的第一频段的AP进行连接)。如果移动终端附近没有可用的第二频段的AP，只有可用的第一频段的AP，移动终端会比较第一WiFi模块和第二WiFi模块在第一频段内的历史信号收发能力，选择在第一频段内的历史信号收发能力较高的WiFi模块在第一频段工作(选择在第一频段内的历史信号收发能力的WiFi模块与附近可搜索到的第一频段的AP进行连接)。
其中，第一WiFi模块在第二频段内的历史信号收发能力基于第一WiFi模块在第二频段内的历史平均发射功率，第一WiFi模块在第二频段内的历史平均传输时延、第一WiFi模块在第二频段内的历史平均丢包率、第一WiFi模块在第二频段内的历史平均下行传输速率、第一WiFi模块在第二频段内的历史平均上行传输速率来确定。
一般而言，第一WiFi模块第二频段内的历史平均发射功率越大，第一WiFi模块在第二频段内的历史信号收发能力越高；第一WiFi模块第二频段内的历史平均传输时延越大，第一WiFi模块在第二频段内的历史信号收发能力越高；第一WiFi模块第二频段内的历史平均丢包率越低，第一WiFi模块在第二频段内的历史信号收发能力越高；第一WiFi模块第二频段内的历史平均下行传输速率越高，第一WiFi模块在第二频段内的历史信号收发能力越高；第一WiFi模块第二频段内的历史平均上行传输速率越高，第一WiFi模块在第二频段内的历史信号收发能力越高。
比如，第一WiFi模块在第二频段内的历史信号收发能力可以采用如下公式来计算：
P＝a1*b1+a2*b2+a3*b3+a4*b4+a5*b5；
其中，P表示第一WiFi模块在第二频段内的历史信号收发能力，b1表示第一WiFi模块在第二频段内的历史平均发射功率、b2表示第一WiFi模块在第二频段内的历史平均传 输时延、b3表示第一WiFi模块在第二频段内的历史平均丢包率、b4表示第一WiFi模块在第二频段内的历史平均下行传输速率、b5表示第一WiFi模块在第二频段内的历史平均上行传输速率。a1、a2、a3、a4、a5为b1、b2、b3、b4、b5分别对应的加权系数。
具体的，移动终端还可以根据前台应用程序的类型与优先需要的信号收发能力的参考指标(信号收发能力的参考指标可以包括平均发射功率、平均丢包率、平均下行传输速率、平均上行传输速率等)的对应关系选择对应的WiFi模块。比如，前台应用程序为游戏类应用，则移动终端会选择在第二频段内平均传输时延最低的WiFi模块工作。又比如，如果前台应用为视频类应用，则移动终端会选择在第二频段内平均下行传输速率最高的WiFi模块工作。本申请实施例可以根据前台应用程序优先需要的信号收发能力的参考指标的大小选择合适的WiFi模块进行工作，从而提高WiFi漫游时前台应用的使用体验。
可选的，图3所示的方法还可以包括如下步骤：
在第二WiFi模块处于断开状态，第一WiFi模块处于连接状态的情况下，若第一WiFi模块处于漫游限制模式，将第一WiFi模块从漫游限制模式切换至限制解除模式，取消第一WiFi模块的漫游频段限制。
其中，第二WiFi模块处于断开状态的原因有多种，比如，第二WiFi模块由于故障、供电等原因停止工作。又比如，由于第二WiFi模块原本被限制在第二频段内漫游，当移动终端附近没有可用的第二频段的AP时，则第二WiFi模块会被迫断开连接。
本申请实施例中，如果第二WiFi模块处于断开状态，只有第一WiFi模块处于连接状态的情况下，如果第一WiFi模块仍处于漫游限制模式，则移动终端可以将第一WiFi模块从漫游限制模式切换至限制解除模式，取消第一WiFi模块的漫游频段限制，允许第一WiFi模块在第一频段和第二频段之间漫游。比如，在第二WiFi模块处于断开状态，只有第一WiFi模块处于连接状态的情况下，允许第一WiFi模块在2.4G频段和5G频段之间漫游。
由于只有一个WiFi模块处于连接状态，并且该WiFi模块支持多个频段，则可以允许该WiFi模块在多个频段内漫游，从而提高单WiFi模块下的网络传输性能。
需要说明的是，图3所示的双WiFi模块中的第一WiFi模块和第二WiFi模块没有明显的主从关系，二者是平等的合作或竞争关系。
请参阅图4，图4是本申请实施例公开的另一种基于双WiFi模块的WiFi漫游方法的流程示意图，如图4所示，该基于双WiFi模块的WiFi漫游方法包括如下步骤。
401，在第一WiFi模块和第二WiFi模块均处于连接状态的情况下，移动终端控制第一 WiFi模块连接的接入点AP工作的频段为第一频段，控制第二WiFi模块连接的AP工作的频段为第二频段，第一频段与第二频段没有重叠。
402，移动终端控制第一WiFi模块处于第一漫游限制模式，限制第一WiFi模块在第一频段内漫游。
本申请实施例中的步骤401至步骤402的具体实施可以参见图2中的步骤201至步骤202，此处不再赘述。
403，移动终端控制第二WiFi模块处于限制解除模式，允许第二WiFi模块漫游。
其中，限制解除模式，是指解除漫游的限制，允许自由漫游，即允许在任意频段内进行漫游的漫游模式。
本申请实施例中，第二WiFi模块为主WiFi模块，允许第二WiFi模块自由漫游，而第一WiFi模块为辅WiFi模块，第一WiFi模块处于第一漫游限制模式，只能在第一频段内漫游。
主WiFi模块，指的是主要使用的WiFi模块，与辅WiFi模块对应，辅WiFi模块是辅助主WiFi模块进行链路聚合的模块。
主WiFi模块的性能指标(比如，发射功率、传输时延、丢包率、下行传输速率、上行传输速率等)一般要优于辅WiFi模块。
链路聚合，是指移动终端可以同时使用两个或者两个以上的网口同时进行上网，指的是把用户的上网请求智能的分配到不同的可上网接口(第一WiFi模块对应的接口、第二WiFi模块对应的接口)上。由于双WiFi模块可以支持两条WiFi通路同时收发数据，移动终端可以将需要传输的数据包分配在第一WiFi通路和第二WiFi通路中传输，从而提高WiFi网络的数据传输量。
本申请实施例中，对于主WiFi模块，不对其进行漫游限制，允许其自由漫游，对于辅WiFi模块，为了避免辅WiFi模块对主WiFi模块的干扰，对其进行漫游限制。可以最大的发挥出主WiFi模块的性能，提高主WiFi模块的数据收发能力。
可选的，在执行步骤402之后，还可以执行如下步骤：
当第二WiFi模块漫游到第一频段后，移动终端将第一WiFi模块断开连接。
本申请实施例中，由于主WiFi模块(第二WiFi模块)可以自由漫游，当主WiFi模块漫游到辅WiFi模块(第一WiFi模块)所连接的AP所工作的频段后，为了优先保证主WiFi模块的工作，则可以主动将辅WiFi模块断开连接，避免辅WiFi模块对主WiFi模块的干扰。
可选的，在执行步骤402之后，还可以执行如下步骤：
当第二WiFi模块漫游到第一频段后，控制第一WiFi模块从第一漫游限制模式切换至第二漫游限制模式，限制第一WiFi模块在第二频段内漫游。
本申请实施例中，由于主WiFi模块(第二WiFi模块)可以自由漫游，当主WiFi模块漫游到辅WiFi模块(第一WiFi模块)所连接的AP所工作的频段后，为了优先保证主WiFi模块的工作，还可以控制辅WiFi模块漫游到其他频段。
比如，当第二WiFi模块漫游到第一频段后，移动终端控制第一WiFi模块从第一漫游限制模式切换至第二漫游限制模式，限制第一WiFi模块在第二频段内漫游。使得第一WiFi模块和第二WiFi模块各自在不同的频段工作，不会相互干扰。在双WiFi模式下，满足主WiFi模块自由漫游的前提下，保证两个WiFi模块同时进行数据收发，进而提高数据收发能力，提高用户体验。
其中，图1至图4中的双WiFi模块中的第一WiFi模块和第二WiFi模块可以集成在同一个WiFi芯片，即移动终端采用单WiFi芯片。图1至图4中的双WiFi模块中的第一WiFi模块和第二WiFi模块也可以分别集成在两个不同的WiFi芯片，即移动终端采用双WiFi芯片。在单WiFi芯片中，当第一WiFi模块和第二WiFi模块工作在同一频段时，即使工作在不同的信道，干扰仍然较大，单WiFi芯片需要分时工作。在双WiFi芯片中，当第一WiFi模块和第二WiFi模块工作在同一频段时，如果工作在不同的信道，干扰相对较小，双WiFi芯片的第一WiFi模块和第二WiFi模块可以同时工作。
上述主要从方法侧执行过程的角度对本申请实施例的方案进行了介绍。可以理解的是，移动终端为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
本申请实施例可以根据上述方法示例对移动终端进行功能单元的划分，例如，可以对应各个功能划分各个功能单元，也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实 现时可以有另外的划分方式。
