WIFI网络利用不充分的问题，本发明实 施例对现有的移动终端进行了改进，将现有移动终端的射频芯片更换为宽频射频芯片， 可以同时检测 3G (例如， TD网络或 WCDMA网络等） 和 WIFI信号， 处理器可以根 据检测到的 WIFI信号的强度， 判断是打开或关闭 WIFI模块， 从而可以实现 WIFI模 块开启或关闭的自动控制， 能尽可能的节省功耗， 同时提高用户体验。 图

设置为对宽频射频芯片 10检测到的 WIFI信号进行处理， 得 到该 WIFI信号的强度值； 处理器 30， 与 3G调制解调器 20连接， 设置为判断 3G调 制解调器 20得到的 WIFI信号的强度值是否达到预设阈值， 如果是， 控制当前处于关 闭状态的 WIFI模块 40打开。 通过本实施例提供的上述移动终端， 宽频射频芯片 10可以同时检测 3G信号和 WIFI信号，从而使得处理器 30可以在当前 WIFI信号的强度达到预定阈值时打开 WIFI 模块 40， 进而便利 WIFI模块 40可以处于常闭状态， 只有在 WIFI信号的强度达到预 定阈值时才打开， 从而节省了移动终端的功耗， 同时也保证了 WIFI网络的利用率。 在本发明实施例的一个优选实施方式中， 为了进一步地充分利用 WIFI 网络， 保 证移动终端当前进行的业务切换成功， WIFI模块 40在打开后，设置为执行 WIFI网络 搜索， 并连接到 WIFI网络， 在连接成功后通知处理器 30， 处理器 30设置为在接收到 WIFI模块 40的通知后，将移动终端当前进行的业务切换到 WIFI网络。采用该实施方 式， 在 WIFI模块 40连接到 WIFI网络成功后， 再将业务切换到 WIFI网络， 从而可以 保证业务切换成功， 避免了由于 WIFI模块 40无法连接 WIFI网络从而导致业务中断 的问题。 在实际应用中，有 WIFI信号的地方很多，但由于有的 WIFI热点是私有的， 因此， 在某些情况下，宽频射频芯片 10搜索到的 WIFI信号的强度可能很高，但却不能使用， 在这种情况下， 为了进一步降低移动终端的功耗， 在本发明实施例的另一个优选实施 方式中， WIFI模块 40还设置为在打开后，确定当前搜索到的 WIFI网络均不可用的情 况下， 自动关闭， 从而可以进一步降低移动终端的功耗。 当移动终端处于某个私有的不可用的 WIFI热点的覆盖范围下时， 在一般情况下， 移动终端在短时间内不会离开该 WIFI热点的覆盖范围， 为了避免宽频射频芯片 10反 复搜索到该 WIFI热点发出的 WIFI信号， 进而使处理器 30反复控制 WIFI模块 40打 开， 在本发明实施例的一个优选实施方式中， WIFI模块 40还设置为在确定当前搜索 到的 WIFI网络均不可用的情况下，禁止处理器 30在预定时间段内打开 WIFI模块 40。 从而可以避免当移动终端在不可用的 WIFI 热点的覆盖范围下移动时， 移动终端的 WIFI模块 40反复被打开和关闭， 从而导致移动终端的能耗的浪费的问题， 并提高了 移动终端的 WIFI模块 40的使用寿命。 在本发明实施例的一个优选实施方式中， 为了使处于打开状态的 WIFI模块 40及 时关闭， 以进一步节约移动终端的功耗， WIFI模块 40还设置为在打开状态下检测移 动终端当前所处位置的 WIFI信号， 向处理器 30发送模式切换请求； 处理器 30还设 置为确定 WIFI模块 40当前检测到的 WIFI信号的强度值小于预设阈值，向 WIFI模块 40发送控制命令， 指示 WIFI模块 40关闭。 采用该实施方式， 可以在 WIFI信号不好 的情况下， 及时关闭 WIFI模块 40， 从而节省移动终端的功耗。 在本发明实施例的另一个优选实施方式中， 为了使移动终端当前的业务不会被中 断， 处理器 30在向 WIFI模块 40发送控制命令， 指示 WIFI模块 40关闭之前， 可以 先将移动终端当前在 WIFI网络进行的业务（例如， PS域业务）切换到 3G， 从而保证 业务的连续性。 由于在实际应用中， 即使 WIFI 网络的信号强度较低， 但由于资费等问题， 用户 还是偏好于使用 WIFI 网络， 因此， 在本发明实施例的一个优选实施方式中， 处理器 30在向 WIFI模块 40发送控制命令，指示 WIFI模块 40关闭之前，还可以提示用户是 否将业务切换到 3G， 如果用户选择否， 则不执行业务切换， 且不关闭 WIFI模块 40， 如果用户选择是， 则处理器 30向 WIFI模块 40发送控制命令， 指示 WIFI模块 40关 闭。 采用该实施方式， 可以满足不同的用户的需求， 进一步提高用户体验。 并且， 在本发明实施例的另一个优选实施方式中， 为了使用户有选择的空间， 该 移动终端还可以包括一个开关模块， 通过该开关模块， 用户可以选择是否开启处理器 30自动控制 WIFI模块 40打开或关闭的功能， 从而可以满足用户的不同需求。 图 2是根据本发明优选实施例的具有 TD模式的移动终端的结构示意图， 如图 2 所示， 该移动终端包括： TD调制解调器（modem)、 宽频射频芯片、 WIFI模块和处理 器模块。 其中， 上述宽频射频芯片， 设置为检测 WIFI信号和 TD信号； 上述 TD modem, 设置为检测和处理宽频射频芯片检测到的 WIFI信号； 上述 WIFI模块， 设置为处理 WIFI信号和进行 WIFI网络的使用等操作； 上述处理器模块， 处理 TD modem上报的数据和 WIFI模块上报的数据， 决定是 否进行 WIFI模块的打开和关闭以及 PS域业务的切换等操作。 在图 2中， 宽频射频芯片把检测到的 WIFI信号送给 TD modem, TD modem把经 过处理后的 WIFI信号的强度值送给处理器模块，处理器模块对接收到的 WIFI信号的 强度值进行逻辑判断， 然后对 WIFI模块进行打开或关闭操作， 同时处理器还要对模 式进行切换。 而 WIFI模块把检测的信号强度送给处理器模块， 处理器模块对接收到 的信号强度进行逻辑判断， 然后对 WIFI模块进行打开或关闭操作， 同时处理器还要 对模式进行切换。从而可以实现 TD模式和 WIFI模式的自动切换，在尽可能使用 WIFI 网络的同时， 提高了用户体验。 图 3是根据本发明实施例的移动终端的 WIFI模块的控制方法的流程图， 如图 3 所示， 该方法主要包括以下步骤： 步骤 S302, 检测移动终端当前所处位置的 WIFI信号。 在本发明实施例中， 为了节约移动终端的功耗， 移动终端的 WIFI终端处于常闭 状态， 只有在检测到当前的 WIFI信号较强时才打开。 在本发明实施例的一个优选实 施方式中， 在 WIFI模块关闭的情况下， 可以由移动终端的 3G通信模块通过宽频射频 芯片检测移动终端当前所处位置的 WIFI信号。 例如， 在图 2所示的移动终端中， 在 移动终端当前工作在 TD模式下时，由宽频射频芯片检测当前的 TD信号和 WIFI信号， 在检测到 WIFI信号时， 将检测到的 WIFI信号传输给 TD调制解调器 （即 TD网络的 通信模块） 处理， TD调制解调器通过处理可以获取到当前 WIFI信号的强度。 由于 WIFI网络在 PS域业务上具有较大的优势， 因此， 在本发明实施例的更为优 选的一个实施方式中， 3G通信模块在进行 PS域业务时， 定时通过宽频射频芯片检测 移动终端当前所处位置的 WIFI信号。 在本发明实施例的另一个优选实施方式中， 如果移动终端当前工作在 WIFI模式 下， 则可以由 WIFI模块检测移动终端当前所处位置的 WIFI信号， 而不由宽频射频芯 片检测， 从而可以提高 WIFI信号的检测效率。 步骤 S304, 根据检测到的 WIFI信号的强度值， 控制移动终端的 WIFI模块打开 或关闭。 在本发明实施例的一个优选实施方式中， 可以通过设置一个预设阈值来判断是否 打开或关闭移动终端的 WIFI模块， 如果检测到的 WIFI信号的强度值到达预设阈值， 且 WIFI模块当前处于关闭状态， 则控制 WIFI模块打开； 如果检测到的 WIFI信号的 强度值小于预设阈值， 且 WIFI模块当前处于打开状态， 则控制 WIFI模块关闭。 采用 该优选实施方式， 可以简化逻辑判断， 易于实现。 在本发明实施例的一个优选实施方式中， 为了进一步地充分利用 WIFI 网络， 保 证移动终端当前进行的业务切换成功， 在 WIFI模块打开之后， WIFI 模块可以执行 WIFI网络搜索并连接搜索到的 WIFI网络， 在连接成功后， 将移动终端当前进行的业 务切换到 WIFI网络。 更为优选地， 由于 WIFI网络对执行 PS域业务更具有优势， 可 以将移动终端当前进行的 PS域业务切换到 WIFI网络。 在实际应用中，有 WIFI信号的地方很多，但由于有的 WIFI热点是私有的， 因此， 在某些情况下， 宽频射频芯片搜索到的 WIFI信号的强度可能很高， 但却不能使用， 在这种情况下， 为了进一步降低移动终端的功耗， 在本发明实施例的另一个优选实施 方式中， WIFI模块在打开后进行 WIFI网络搜索， 如果确定当前搜索到的 WIFI网络 均不可用， 则 WIFI模块自动关闭。 当移动终端处于某个私有的不可用的 WIFI热点的覆盖范围下时， 在一般情况下， 移动终端在短时间内不会离开该 WIFI 热点的覆盖范围， 为了避免反复打开和关闭 WIFI模块， 在本发明实施例的一个更优的实施方式中， WIFI模块确定当前搜索到的 WIFI网络均不可用之后， 还可以进一步在预定时间段内禁止被打开。从而可以避免当 移动终端在不可用的 WIFI热点的覆盖范围下移动时，移动终端的 WIFI模块反复被打 开或关闭， 从而导致移动终端的能耗的浪费的问题， 并提高了移动终端的 WIFI模块 的使用寿命。 在本发明实施例的另一个优选实施方式中， 为了使处于打开状态的 WIFI模块及 时关闭， 如果移动终端当前所处位置的 WIFI信号的强度值小于预设阈值， 则处理器 对模式进行切换， 然后控制 WIFI模块关闭。 采用该优选实施方式， 可以在 WIFI信号 不好的情况下， 及时关闭 WIFI模块， 从而节省移动终端的功耗。 在本发明实施例的另一个优选实施方式中， 为了使移动终端当前的业务不会被中 断， 在 WIFI模块当前正在执行业务的情况下， 处理器在控制 WIFI模块关闭之前， 处 理器将该业务 （例如， 将 PS域业务） 切换到 3G， 例如， TD网络， 从而可以确保移 动终端当前的业务不会被中断。 由于在实际应用中， 即使 WIFI 网络的信号强度较低， 但由于资费等问题， 用户 还是偏好于使用 WIFI 网络， 因此， 在本发明实施例的一个优选实施方式中， 在控制 WIFI模块关闭之前， 移动终端可以提示用户是否关闭 WIFI 模块， 在用户选择关闭 WIFI模块的情况下， 处理器控制 WIFI模块关闭， 如果用户选择不关闭 WIFI模块， 则继续在 WIFI网络下执行当前业务。 采用本发明实施例提供的上述方法， 可以自动打开或关闭移动终端的 WIFI模块， 以图 2所示的具有 TD模式的移动终端为例， 在本发明实施例中， TD modem通过宽 频射频芯片实时检测 WIFI信号， 如果检测到 WIFI信号并且信号比较好， 则自动打开 WIFI模块，然后把 PS域业务切换到 WIFI上，否则仍然使用 TD网络进行 PS域业务。 如果在使用 WIFI的时候检测到信号比较弱， 不满足使用要求， 则把 PS域业务切换到 TD网络上， 然后关闭 WIFI模块。 从而可以减少打开 WIFI模块的时间， 降低手机功 耗， 从而延长手机的使用时间， 提高用户体验。 在本发明一个优选实施例中， 具有 TD模式的移动终端可以通过以下步骤执行模 式切换中以降低功耗： 步骤 1， 将移动终端的射频芯片更换为宽频射频芯片， 可以同时检测 TD信号和 WIFI信号。 步骤 2， TD modem在工作的同时定时通过宽频射频芯片检测 WIFI信号， 如果检 测到 WIFI信号， 则把 WIFI的信号强度传送给处理器， 然后继续进行信号检测。 步骤 3， 处理器对 WIFI的信号强度进行判断， 如果信号强度符合网络使用要求， 则发送打开 WIFI模块的命令， 同时把 PS域业务从 TD网络切换到 WIFI网络， 如果 不满足使用要求， 则不做任何处理。 步骤 4， 在使用 WIFI网络的时候， 如果检测到 WIFI信号比较弱， 不满足继续使 用的要求，则处理器把 PS域业务先切换到 TD网络，然后发送关闭 WIFI模块的命令。 通过上述优选实施例，可以在充分利用 WIFI网络的同时减少 WIFI模块打开的时 间， 降低移动终端的功耗， 从而延长移动终端的使用时间， 提高用户体验。 下面分别以图 2所示的移动终端的 PS域业务从 TD网络切换到 WIFI网络以及从 WIFI网络切换到 TD网络为例， 对本发明实施例提供的技术方案进行说明。 图 4是根据本发明优选实施例的移动终端的 PS域业务从 TD网络切换到 WIFI网 络的流程图， 如图 4所示， PS域业务从 TD网络切换到 WIFI网络主要包括以下步骤： 步骤 S401 , 移动终端在 TD网络启动 PS域业务。 步骤 S402， TD modem定时通过宽频射频芯片检测 WIFI信号， 如果没有检测到 WIFI信号， 则继续进行检测； 如果检测到 WIFI信号， 则把 WIFI信号的强度上报给 处理器。 步骤 S403 , 处理器在接收到 WIFI信号的强度后， 对该 WIFI信号的强度进行判 断。 步骤 S404, 处理器判断该 WIFI信号的强度值与预先设定的强度值进行比较， 如 果信号值比设定的值大， 则表明 WIFI信号比较好， 可以进行使用， 则执行步骤 S405, 如果接收到的 WIFI信号的强度比预先设定的强度值小，则表明现在的 WIFI信号不能 满足使用要求， 处理器则进行舍弃， 不做任何动作， 返回执行步骤 S402。 步骤 S405， 处理器发出打开 WIFI模块的命令， WIFI模块打开。 步骤 S406， WIFI模块进行网络搜索和连接， 在一切都准备好以后向处理器发送 一个就绪信号， 处理器在接收到该信号以后确定 WIFI模块可用。 步骤 S407, 处理器把 PS域业务从 TD网络切换到 WIFI网络。 因为现在有 WIFI信号的地方很多， 并且其中有些是私有的， 并不能使用， 因此， 在上述步骤 S406中， 在 WIFI模块打开以后会出现 WIFI热点不能使用情况， WIFI模 块将进一步搜索判断周围是否有可以使用的 WIFI热点， 如果没有， 则自动关闭 WIFI 模块， 并且在一定时间内禁止对 WIFI模块执行打开操作。 在该优选实施例中， 在步 骤 S404中判断 WIFI信号强度是否满足使用时，可以将预先设定的强度值设置大些 (强 度值可以由用户自己修改）， 因为在可以使用 WIFI网络的地方 WIFI信号都比较好， 将该强度值设置较大， 可以排除一些信号的干扰。 图 5是根据本发明优选实施例的移动终端的 PS域业务从 WIFI网络切换到 TD网 络的流程图， 如图 5所示， PS域业务从 WIFI网络切换到 TD网络主要包括以下步骤： 步骤 S501 , 移动终端在 WIFI网络启动 PS域业务。 步骤 S502， 在使用 WIFI网络的时候， WIFI模块检测当前的 WIFI信号强度。 步骤 S503 , 处理器模块对检测到的 WIFI信号强度进行判断。 步骤 S504, 处理器模块判断当前的 WIFI信号强度是否满足使用要求， 例如， 可 以判断当前的 WIFI信号强度是否大于预先设定的强度值，如果 WIFI信号强度不能满 足使用要求， 则执行步骤 S505; 如果 WIFI信号强度能够满足使用要求， 则返回执行 步骤 S502。 步骤 S505，处理器模块对网络模式进行切换，将把 PS域业务从 WIFI网络切换到 TD网络， 然后发送关闭 WIFI模块的命令。 步骤 S506, 关闭 WIFI模块。 如果用户在 WIFI信号比较弱的情况下仍然继续想继续使用 WIFI网络进行 PS域 业务，则在上述步骤 S505中，处理器在进行网络模式切换时，可以提示用户是否切换， 如果用户不切换， 则继续在 WIFI网络执行 PS域业务， 不关闭 WIFI模块， 从而可以 满足用户的不同需求， 提高用户体验。 虽然上述以具有 TD模式的移动终端为例进行说明， 但并不限于此， 对于各种具 有 WIFI功能的移动终端， 本发明实施例提供的技术方案均适用。 为了满足用户的不同需求， 本发明实施例提供的上述技术方案可以作为对现有 WIFI模块打开或关闭控制的一个补充， 可以由用户选择的是否执行 WIFI模块的自动 打开或关闭。 从以上的描述中， 可以看出， 本发明实施例提供的上述技术方案在硬件只需把原 来的射频芯片更换为宽频射频芯片， 当通过宽频射频芯片检测到 WIFI信号可以满足 使用的时候打开 WIFI模块， 把业务切换到 WIFI网络， 在 WIFI信号不满足使用的时 候， 把业务切换到公共网络。 从而既能很好的降低终端的功耗， 又很好的提升了用户 体验的效果。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In view of the problem that the power consumption of the mobile terminal is large due to the WIFI module being always on, and the WIFI network is insufficiently used by the user to control the WIFI module to be turned on or off, the embodiment of the present invention is applicable to the existing mobile The terminal has been improved to replace the RF chip of the existing mobile terminal with a broadband RF chip, and can simultaneously detect 3G (for example, TD network or WCDMA network) and WIFI signals, and the processor can judge according to the strength of the detected WIFI signal. It is to turn the WIFI module on or off, so that the automatic control of the WIFI module can be turned on or off, which can save power as much as possible and improve the user experience. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention. As shown in FIG. 1, a mobile terminal according to an embodiment of the present invention mainly includes: a broadband RF chip 10, a 3G modem 20, a processor 30, and a WIFI module 40. The broadband RF chip 10 is configured to detect the 3G signal and the WIFI signal of the current location of the mobile terminal, and transmit the detected WIFI signal to the 3G modem 20; the 3G modem 20 is connected to the broadband RF chip 10, and is set to be broadband. The WIFI signal detected by the RF chip 10 is processed to obtain the intensity value of the WIFI signal. The processor 30 is connected to the 3G modem 20, and is configured to determine whether the strength value of the WIFI signal obtained by the 3G modem 20 reaches a preset threshold. , the WIFI module 40 that controls the currently closed state is turned on. With the above-mentioned mobile terminal provided by the embodiment, the broadband RF chip 10 can simultaneously detect the 3G signal and the WIFI signal, so that the processor 30 can open the WIFI module 40 when the intensity of the current WIFI signal reaches a predetermined threshold, thereby facilitating the WIFI module 40. In the normally closed state, it is only turned on when the strength of the WIFI signal reaches a predetermined threshold, thereby saving power consumption of the mobile terminal and ensuring the utilization of the WIFI network. In a preferred embodiment of the present invention, in order to further fully utilize the WIFI network, and ensure that the current service switching of the mobile terminal is successful, the WIFI module 40 is configured to perform a WIFI network search and connect to the WIFI network after being opened. After the connection is successful, the processor 30 is notified, and the processor 30 is configured to switch the current service performed by the mobile terminal to the WIFI network after receiving the notification of the WIFI module 40. With this implementation, after the WIFI module 40 is successfully connected to the WIFI network, the service is switched to the WIFI network, so that the service switching success can be ensured, and the problem that the service is interrupted due to the failure of the WIFI module 40 to connect to the WIFI network is avoided. In practical applications, there are many places where there are WIFI signals, but since some WIFI hotspots are private, in some cases, the strength of the WIFI signal searched by the broadband RF chip 10 may be high, but it cannot be used. In this case, in order to further reduce the power consumption of the mobile terminal, another preferred implementation of the embodiment of the present invention In the mode, the WIFI module 40 is further configured to automatically shut down when the currently searched WIFI network is unavailable after being opened, so that the power consumption of the mobile terminal can be further reduced. When the mobile terminal is in the coverage of a private unavailable WIFI hotspot, in general, the mobile terminal does not leave the coverage of the WIFI hotspot in a short time, in order to prevent the broadband RF chip 10 from repeatedly searching for the In the preferred embodiment of the present invention, the WIFI module 40 is further configured to determine that the currently searched WIFI network is unavailable. Next, the processor 30 is prohibited from turning on the WIFI module 40 for a predetermined period of time. Therefore, when the mobile terminal moves under the coverage of the unavailable WIFI hotspot, the WIFI module 40 of the mobile terminal is repeatedly turned on and off, thereby causing waste of energy consumption of the mobile terminal, and improving the WIFI of the mobile terminal. The service life of module 40. In a preferred embodiment of the present invention, in order to turn off the WIFI module 40 in an open state to further save power consumption of the mobile terminal, the WIFI module 40 is further configured to detect the current location of the mobile terminal in an open state. The WIFI signal sends a mode switching request to the processor 30. The processor 30 is further configured to determine that the strength value of the WIFI signal currently detected by the WIFI module 40 is less than a preset threshold, and send a control command to the WIFI module 40, indicating that the WIFI module 40 is turned off. . With this embodiment, the WIFI module 40 can be turned off in time when the WIFI signal is not good, thereby saving power consumption of the mobile terminal. In another preferred embodiment of the present invention, in order to prevent the current service of the mobile terminal from being interrupted, the processor 30 may first send the mobile terminal to the WIFI module 40 before the WIFI module 40 is turned off. The services performed on the WIFI network (for example, PS domain services) are switched to 3G to ensure continuity of services. In practical applications, even if the signal strength of the WIFI network is low, the user prefers to use the WIFI network due to problems such as tariffs. Therefore, in a preferred embodiment of the embodiment of the present invention, the processor 30 is in the WIFI module. The control command is sent to indicate that the user switches the service to 3G before the WIFI module 40 is turned off. If the user selects No, the service switching is not performed, and the WIFI module 40 is not turned off. If the user selects yes, the processor 30 A control command is sent to the WIFI module 40 to instruct the WIFI module 40 to shut down. With this implementation manner, the needs of different users can be met, and the user experience is further improved.

In FIG. 2, the broadband RF chip sends the detected WIFI signal to the TD modem, and the TD modem sends the processed WIFI signal strength value to the processor module, and the processor module performs the intensity value of the received WIFI signal. The logic judges, then the WIFI module is turned on or off, and the processor also switches the mode. The WIFI module sends the detected signal strength to the processor module, and the processor module logically judges the received signal strength, and then turns on or off the WIFI module, and the processor also switches the mode. Thereby, the automatic switching between the TD mode and the WIFI mode can be realized, and the user experience is improved while using the WIFI network as much as possible. FIG. 3 is a flowchart of a method for controlling a WIFI module of a mobile terminal according to an embodiment of the present invention. As shown in FIG. 3, the method mainly includes the following steps: Step S302: Detect a WIFI signal of a location where the mobile terminal is currently located. In the embodiment of the present invention, in order to save power consumption of the mobile terminal, the WIFI terminal of the mobile terminal is in a normally closed state, and is only turned on when it is detected that the current WIFI signal is strong. In a preferred embodiment of the present invention, in a case where the WIFI module is turned off, the WIFI signal of the current location of the mobile terminal may be detected by the 3G communication module of the mobile terminal through the broadband radio frequency chip. For example, in the mobile terminal shown in FIG. 2, when the mobile terminal is currently working in the TD mode, the current TD signal and the WIFI signal are detected by the broadband radio frequency chip, and when the WIFI signal is detected, the detected WIFI signal is transmitted. The TD modem (ie, the communication module of the TD network) is processed, and the TD modem can obtain the strength of the current WIFI signal through processing. Because the WIFI network has a large advantage in the PS domain service, in a more preferred embodiment of the embodiment of the present invention, the 3G communication module periodically detects the current mobile terminal through the broadband radio frequency chip when performing the PS domain service. The WIFI signal at the location. In another preferred embodiment of the present invention, if the mobile terminal is currently working in the WIFI mode, the WIFI module can detect the WIFI signal of the current location of the mobile terminal, instead of being detected by the broadband radio frequency chip, thereby improving the WIFI. Signal detection efficiency. Step S304, controlling the WIFI module of the mobile terminal to be turned on or off according to the detected intensity value of the WIFI signal. In a preferred embodiment of the present invention, whether the WIFI module of the mobile terminal is turned on or off is determined by setting a preset threshold, if the detected WIFI signal strength value reaches a preset threshold, and the WIFI module is currently in the If the detected WIFI signal is less than the preset threshold and the WIFI module is currently in the open state, the control WIFI module is turned off. With this preferred embodiment, logical decisions can be simplified and are easy to implement. In a preferred implementation manner of the embodiment of the present invention, in order to further fully utilize the WIFI network, the current service switching performed by the mobile terminal is successful, and after the WIFI module is opened, the WIFI module can perform a WIFI network search and connect to the searched WIFI network. After the connection is successful, the current service of the mobile terminal is switched to the WIFI network. More preferably, since the WIFI network has an advantage in performing the PS domain service, the PS domain service currently performed by the mobile terminal can be switched to the WIFI network. In practical applications, there are many places where there are WIFI signals, but since some WIFI hotspots are private, in some cases, the strength of the WIFI signal searched by the broadband RF chip may be high, but it cannot be used. In this case, in order to further reduce the power consumption of the mobile terminal, in another preferred embodiment of the embodiment of the present invention, the WIFI module performs a WIFI network search after being opened, and if it is determined that the currently searched WIFI network is unavailable, The WIFI module is automatically turned off. When the mobile terminal is in the coverage of a private unavailable WIFI hotspot, in general, the mobile terminal does not leave the coverage of the WIFI hotspot in a short time, in order to avoid repeatedly opening and closing the WIFI module, In a preferred implementation manner of the embodiment of the present invention, after the WIFI module determines that the currently searched WIFI network is unavailable, the WIFI module may further prohibit being opened within a predetermined time period. Therefore, when the mobile terminal moves under the coverage of the unavailable WIFI hotspot, the WIFI module of the mobile terminal is repeatedly turned on or off, thereby causing waste of energy consumption of the mobile terminal, and improving the WIFI module of the mobile terminal. The service life. In another preferred embodiment of the present invention, in order to turn off the WIFI module in an open state, if the intensity value of the WIFI signal of the current location of the mobile terminal is less than a preset threshold, the processor switches the mode. Then control the WIFI module to shut down. With the preferred embodiment, the WIFI module can be turned off in time when the WIFI signal is not good, thereby saving power consumption of the mobile terminal. In another preferred embodiment of the embodiment of the present invention, in order to prevent the current service of the mobile terminal from being interrupted, in the case that the WIFI module is currently performing the service, the processor controls the service before the WIFI module is shut down. (For example, the PS domain service) is switched to 3G, for example, the TD network, so that the current service of the mobile terminal is not interrupted. In a practical application, even if the signal strength of the WIFI network is low, the user prefers to use the WIFI network due to the problem of the tariff, etc. Therefore, in a preferred embodiment of the embodiment of the present invention, before controlling the WIFI module to be closed, The mobile terminal can prompt the user to close the WIFI module. When the user chooses to close the WIFI module, the processor controls the WIFI module to be closed. If the user chooses not to close the WIFI module, the current service is continued under the WIFI network. With the above method provided by the embodiment of the present invention, the WIFI module of the mobile terminal can be automatically turned on or off. The mobile terminal with the TD mode shown in FIG. 2 is taken as an example. In the embodiment of the present invention, the TD modem passes the broadband radio frequency chip in real time. Detecting the WIFI signal, if the WIFI signal is detected and the signal is better, the WIFI module is automatically turned on, and then the PS domain service is switched to the WIFI, otherwise the TD network is still used for the PS domain service. If the signal detected is weak when using WIFI and the usage requirement is not met, the PS domain service is switched to the TD network, and then the WIFI module is turned off. Thereby, the time for opening the WIFI module can be reduced, and the power consumption of the mobile phone can be reduced, thereby prolonging the use time of the mobile phone and improving the user experience. In a preferred embodiment of the present invention, the mobile terminal having the TD mode can perform mode switching to reduce power consumption by the following steps: Step 1. Replace the radio frequency chip of the mobile terminal with a broadband radio frequency chip, and simultaneously detect the TD signal and the WIFI. signal. Step 2: The TD modem periodically detects the WIFI signal through the broadband RF chip while working. If the WIFI signal is detected, the signal strength of the WIFI is transmitted to the processor, and then the signal detection is continued. Step 3: The processor determines the signal strength of the WIFI. If the signal strength meets the network usage requirements, the command to open the WIFI module is sent, and the PS domain service is switched from the TD network to the WIFI network. If the usage requirement is not met, then Do any processing. Step 4: When using the WIFI network, if it is detected that the WIFI signal is weak and does not satisfy the requirement for continued use, the processor first switches the PS domain service to the TD network, and then sends a command to close the WIFI module. Through the above preferred embodiment, the time of opening the WIFI module can be reduced while the WIFI network is fully utilized, and the power consumption of the mobile terminal can be reduced, thereby prolonging the use time of the mobile terminal and improving the user experience. The technical solutions provided by the embodiments of the present invention are described below by taking the example of the PS domain service of the mobile terminal shown in FIG. 2, which is switched from the TD network to the WIFI network and the WIFI network to the TD network. 4 is a flowchart of switching a PS domain service of a mobile terminal from a TD network to a WIFI network according to a preferred embodiment of the present invention. As shown in FIG. 4, the PS domain service switching from the TD network to the WIFI network mainly includes the following steps: Step S401 The mobile terminal starts the PS domain service in the TD network. Step S402, the TD modem periodically detects the WIFI signal through the broadband radio frequency chip, and if the WIFI signal is not detected, continues to perform the detection; if the WIFI signal is detected, reports the strength of the WIFI signal to the processor. Step S403, after receiving the strength of the WIFI signal, the processor determines the strength of the WIFI signal. Step S404, the processor determines that the intensity value of the WIFI signal is compared with a preset intensity value. If the signal value is greater than the set value, it indicates that the WIFI signal is better and can be used, and then step S405 is performed, if receiving If the intensity of the WIFI signal is smaller than the preset intensity value, it indicates that the current WIFI signal cannot meet the usage requirement, and the processor discards and does not perform any action, and returns to step S402. Step S405, the processor issues a command to open the WIFI module, and the WIFI module is turned on. Step S406, the WIFI module performs network search and connection, and sends a ready signal to the processor after everything is ready. After receiving the signal, the processor determines that the WIFI module is available. Step S407, the processor switches the PS domain service from the TD network to the WIFI network. Because there are many places where there are WIFI signals, and some of them are private, they cannot be used. Therefore, in the above step S406, after the WIFI module is opened, the WIFI hotspot cannot be used, and the WIFI module will further search to determine whether there is any surrounding. The WIFI hotspot that can be used, if not, automatically closes the WIFI module, and prohibits the opening operation of the WIFI module for a certain period of time. In the preferred embodiment, when it is determined in step S404 whether the WIFI signal strength is satisfied, the preset intensity value may be set larger (the intensity value may be modified by the user), because the WIFI network can be used in the place where WIFI can be used. The signal is better, and the intensity value is set larger, which can eliminate some signal interference. FIG. 5 is a flowchart of switching a PS domain service of a mobile terminal from a WIFI network to a TD network according to a preferred embodiment of the present invention. As shown in FIG. 5, the PS domain service switching from the WIFI network to the TD network mainly includes the following steps: Step S501 The mobile terminal starts the PS domain service on the WIFI network. Step S502, when using the WIFI network, the WIFI module detects the current WIFI signal strength. Step S503, the processor module determines the detected WIFI signal strength. Step S504, the processor module determines whether the current WIFI signal strength meets the usage requirement, for example, whether the current WIFI signal strength is greater than a preset strength value, and if the WIFI signal strength cannot meet the usage requirement, step S505 is performed; If the WIFI signal strength can meet the usage requirements, the process returns to step S502. Step S505, the processor module switches the network mode, and switches the PS domain service from the WIFI network to the TD network, and then sends a command to close the WIFI module. Step S506, the WIFI module is turned off. If the user continues to use the WIFI network for the PS domain service if the WIFI signal is still weak, the processor may prompt the user whether to switch when the network mode is switched in the foregoing step S505. If the user does not switch, The PS domain service is continuously executed on the WIFI network, and the WIFI module is not closed, thereby satisfying different needs of users and improving the user experience.
