终端的网络切换方法及终端设备Terminal network switching method and terminal device

技术领域technical field

本发明涉及无线通信技术领域，尤其涉及一种终端的网络切换方法及终端设备。The present invention relates to the technical field of wireless communication, and in particular, to a network switching method of a terminal and a terminal device.

背景技术Background technique

目前，双卡或多卡终端已经广泛普及，但是由于多卡终端都是由各个芯片厂商各自提供的多卡支持，对于多卡终端没有统一的定义，多卡终端能够自动进行数据业务卡的切换方式通常为：首先由用户根据自身需求主动选择终端的某张客户识别模块(Subscriber Identity Module，简称：SIM)卡作为默认数据业务卡，之后随着数据业务的使用情况，终端系统通过监测该默认数据业务卡的流量状况，判断是否需要进行数据业务卡切换。当默认数据业务卡的流量剩余较少时，控制切换到另一个数据业务卡。At present, dual-card or multi-card terminals have been widely popularized, but since multi-card terminals are supported by multi-card provided by each chip manufacturer, there is no unified definition for multi-card terminals, and multi-card terminals can automatically switch data service cards. The method is usually as follows: first, the user actively selects a certain Subscriber Identity Module (SIM) card of the terminal as the default data service card according to his own needs, and then the terminal system monitors the default data service according to the usage of the data service. The traffic status of the data service card is used to determine whether it is necessary to switch the data service card. When the remaining traffic of the default data service card is less, the control switches to another data service card.

另外，在终端使用某一数据业务卡进行数据业务的过程中，根据网络类型优先级，在多卡终端的硬件支持的前提下，优先选择4G网络，当4G网络无信号时尝试连接3G网络，如果3G网络无信号时，尝试切换2G网络，即在用户选择了某一数据业务卡之后，根据网络情况选择合适的网络类型。In addition, when the terminal uses a data service card for data service, according to the priority of the network type, on the premise of the hardware support of the multi-card terminal, the 4G network is preferentially selected, and when the 4G network has no signal, it tries to connect to the 3G network. If the 3G network has no signal, try to switch the 2G network, that is, after the user selects a data service card, select the appropriate network type according to the network situation.

然而，上述的方式只是根据数据业务卡的剩余流量就进行卡间的网络切换，或者简单的根据网络状况进行卡内的网络切换，容易导致切换后的网络状况差或者剩余流量较少，网络切换的准确度较低。However, the above method only performs network switching between cards according to the remaining traffic of the data service card, or simply performs network switching within the card according to the network conditions, which may easily lead to poor network conditions or less remaining traffic after switching, and network switching of lower accuracy.

具体实施方式Detailed ways

为使本发明实施例的目的、技术方案和优点更加清楚，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，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

图1为本发明实施例提供的一种网络系统示意图，参照图1，该网络系统中包括：基站1、基站2、基站3、终端(也可以称为终端设备)；FIG. 1 is a schematic diagram of a network system according to an embodiment of the present invention. Referring to FIG. 1 , the network system includes: a base station 1, a base station 2, a base station 3, and a terminal (also referred to as a terminal device);

其中，终端可以为智能手机、平板电脑等可以通过数据卡连接网络进行数据业务的设备。The terminal may be a device such as a smart phone, a tablet computer, etc., which can be connected to a network through a data card to perform data services.

终端设置有两个或者两个以上的数据卡(也可以称为数据业务卡)，数据业务卡1和数据业务卡2；数据业务卡1支持运营商1提供的4G网络、3G网络和2G网络；数据业务卡2支持运营商2提供的4G网络、3G网络和2G网络。The terminal is provided with two or more data cards (also called data service cards), data service card 1 and data service card 2; data service card 1 supports 4G network, 3G network and 2G network provided by operator 1 ; Data service card 2 supports 4G network, 3G network and 2G network provided by operator 2.

基站1能够提供运营商1的网络服务；基站2能够提供运营商2的网络服务；基站3能够提供运营商1和运营商2的网络服务。Base station 1 can provide network services of operator 1; base station 2 can provide network services of operator 2; base station 3 can provide network services of operators 1 and 2.

进一步地，对于4G网络、3G网络和2G网络，可以预先设置网络类型优先级，例如，2G网络的带宽低于3G网络的带宽；3G网络的带宽低于4G网络的带宽，因此，默认网络的网络类型优先级为：4G网络>3G网络>2G网络。网络的网络类型优先级可以预先通过基站通知终端，也可以预置在该终端内；可选的，也可以有用户自定义不同网络的优先级。Further, for the 4G network, 3G network and 2G network, the network type priority can be preset, for example, the bandwidth of the 2G network is lower than that of the 3G network; the bandwidth of the 3G network is lower than the bandwidth of the 4G network, therefore, the default network The network type priority is: 4G network>3G network>2G network. The network type priority of the network can be notified to the terminal through the base station in advance, or can be preset in the terminal; optionally, the priority of different networks can also be customized by the user.

参照图1，该终端能够接收到基站1、基站2和基站3发射的信号，终端基于接收到的信号，生成基站信息列表，该列表包含所述至少一个可使用的网络的信号强度值、所述至少一个可使用的网络的网络类型优先级、所述当前服务网络的信号强度、所述当前服务网络的网络类型优先级。Referring to FIG. 1 , the terminal can receive signals transmitted by base station 1, base station 2 and base station 3, and the terminal generates a base station information list based on the received signals, the list including the signal strength value of the at least one available network, all The network type priority of the at least one available network, the signal strength of the current serving network, and the network type priority of the current serving network.

其中，该基站信息列表中存储了每个可以连接到的基站的信息，可选的，该基站的信息可以包括移动电话国家代码(Mobile Country Code，简称：MCC)\移动设备网络代码(Mobile Network Code，简称：MNC)\位置区编码(location area code，简称：LAC)；以及基站标识，可以根据该些信息获取当该基站对应的网络信号强度，以及网络类型等。The base station information list stores information about each base station that can be connected to. Optionally, the base station information may include a mobile phone country code (Mobile Country Code, MCC for short) \ mobile device network code (Mobile Network Code Code, abbreviation: MNC)\location area code (location area code, abbreviation: LAC); and base station identifier, the network signal strength and network type corresponding to the base station can be obtained according to the information.

假设，终端使用数据业务卡1，并已接入基站1提供的3G网络，则该3G网络对应基站信息列表中的当前服务网络，而终端接收到基站2提供的网络和和基站3提供的网络，对应基站信息列表中的所述至少一个可使用的网络；Assuming that the terminal uses the data service card 1 and has access to the 3G network provided by the base station 1, the 3G network corresponds to the current service network in the base station information list, and the terminal receives the network provided by the base station 2 and the network provided by the base station 3. , corresponding to the at least one available network in the base station information list;

进一步的，终端还可以通过终端的流量管理模块，获取数据业务卡1的流量使用情况和数据业务卡2的流量使用情况。例如，获取数据业务卡1对应运营商的网络剩余可用流量和数据业务卡2对应运营商的网络剩余可用流量；基于上文当前服务网络和可使用的网络的划分方式，基站信息列表还可以包括：所述至少一个可使用的网络对应运营商的网络剩余流量、所述当前服务网络对应运营商的网络剩余流量，该处的剩余流量指的是剩余的可用的流量，即在用户已经支付的流量包中还未使用的流量。Further, the terminal can also obtain the traffic usage of the data service card 1 and the traffic usage of the data service card 2 through the traffic management module of the terminal. For example, obtain the remaining available network traffic of the operator corresponding to the data service card 1 and the remaining available network traffic of the operator corresponding to the data service card 2; : the remaining network traffic of the operator corresponding to the at least one usable network, and the remaining network traffic of the operator corresponding to the current serving network, where the remaining traffic refers to the remaining available traffic, that is, after the user has paid Traffic that has not been used in a traffic packet.

由于终端的移动性和网络资源的变化，终端需要对上述基站信息列表进行维护和更新，并基于基站信息列表包含的参数判断当前服务网络是否为最优网络，若存在能够为用户提供更高质量网络服务或者更满足用户资费需求的可使用的网络，则终端进行网络切换。Due to the mobility of the terminal and changes in network resources, the terminal needs to maintain and update the above-mentioned base station information list, and judge whether the current serving network is the optimal network based on the parameters contained in the base station information list. If a network service is available or an available network that better meets the user's tariff requirements, the terminal performs network switching.

对于终端如何基于基站信息列表包含的参数判断当前服务网络是否为最优网络，存在多种可行的实现方式，下面对几种可行的实现方式进行说明：There are many feasible implementations for how the terminal determines whether the current serving network is the optimal network based on the parameters included in the base station information list. The following describes several feasible implementations:

方式一：终端监听网络变化，若接收到新的基站发送的信号，则更新上文基站信息列表；例如，终端接收到基站3发送的信号，则更新基站信息列表，更新后的基站信息列表包含：基站3提供的可使用的网络的信号强度值、基站3提供的可使用的网络的网络类型优先级、基站3提供的可使用的网络对应运营商的网络剩余可用流量；基站2提供的可使用的网络的信号强度值、基站2提供的可使用的网络的网络类型优先级、基站2提供的可使用的网络对应运营商的网络剩余可用流量；基站1提供的当前服务网络的信号强度值、基站1提供的当前服务网络的网络类型优先级、基站1提供的当前服务网络对应运营商的网络剩余可用流量。Mode 1: The terminal monitors network changes, and if it receives a signal sent by a new base station, it updates the base station information list above; for example, when the terminal receives a signal sent by base station 3, it updates the base station information list, and the updated base station information list contains : the signal strength value of the usable network provided by the base station 3, the network type priority of the usable network provided by the base station 3, the remaining available network traffic of the operator corresponding to the usable network provided by the base station 3; the usable network provided by the base station 2 The signal strength value of the network used, the network type priority of the available network provided by the base station 2, the remaining available network traffic of the operator corresponding to the available network provided by the base station 2; the signal strength value of the current service network provided by the base station 1 , the network type priority of the current service network provided by the base station 1, and the remaining available network traffic of the operator corresponding to the current service network provided by the base station 1.

进一步的，终端将基站3提供的可使用的网络的网络类型优先级与基站1提供的当前服务网络的网络类型优先级进行比较；结果为：基站3提供的运营商2的4G网络的网络类型优先级大于基站1提供的运营商1的3G网络的网络类型；则终端比较运营商2的网络剩余可用流量与运营商1的网络剩余可用流量。若运营商2的网络剩余可用流量大于或等于运营商1的网络剩余可用流量，则终端将网络切换至基站3提供的运营商2的4G网络。需要说明的，在切换至基站3提供的运营商2的4G网络时，终端首先将当前服务的数据业务卡切换从数据业务卡1至数据业务卡2，再进行网络的切换。Further, the terminal compares the network type priority of the available network provided by the base station 3 with the network type priority of the current service network provided by the base station 1; the result is: the network type of the 4G network of the operator 2 provided by the base station 3 The priority is greater than the network type of the 3G network of the operator 1 provided by the base station 1; then the terminal compares the remaining available traffic of the network of the operator 2 with the remaining available traffic of the network of the operator 1. If the remaining available network traffic of operator 2 is greater than or equal to the remaining available network traffic of operator 1, the terminal switches the network to the 4G network of operator 2 provided by base station 3. It should be noted that when switching to the 4G network of operator 2 provided by base station 3, the terminal first switches the currently serving data service card from data service card 1 to data service card 2, and then performs network switching.

方式二：终端监听信号强度变化，若基站1提供的当前服务网络的信号强度值低于第一预置信号强度阈值，则终端在基站信息列表中查询网络类型优先级等于或大于基站1提供的当前服务网络的网络类型优先级的网络，例如，基站2提供的4G网络的网络类型优先级高于基站1提供的3G网络。进一步的，终端比较基站2提供的4G网络的剩余可用流量与基站1提供的3G网络的剩余可用流量，若基站2提供的4G网络的剩余可用流量大于或等于基站1提供的3G网络的剩余可用流量，则终端将网络切换至基站2提供的4G网络。需要说明的，在切换至基站3提供的运营商2的4G网络时，终端首先将当前服务的数据业务卡切换从数据业务卡1至数据业务卡2，再进行网络的切换。Method 2: The terminal monitors the signal strength change. If the signal strength value of the current serving network provided by the base station 1 is lower than the first preset signal strength threshold, the terminal will query the base station information list. The priority of the network type is equal to or greater than that provided by the base station 1. The network with the network type priority of the current serving network, for example, the network type priority of the 4G network provided by the base station 2 is higher than that of the 3G network provided by the base station 1 . Further, the terminal compares the remaining available traffic of the 4G network provided by the base station 2 with the remaining available traffic of the 3G network provided by the base station 1, if the remaining available traffic of the 4G network provided by the base station 2 is greater than or equal to the remaining available traffic of the 3G network provided by the base station 1 traffic, the terminal switches the network to the 4G network provided by the base station 2. It should be noted that when switching to the 4G network of operator 2 provided by base station 3, the terminal first switches the currently serving data service card from data service card 1 to data service card 2, and then performs network switching.

方式三：终端监听当前服务网络对应运营商的网络剩余可用流量，若该网络剩余可用流量低于第一预置流量阈值，则终端在基站信息列表中查询网络类型优先级等于或大于基站1提供的当前服务网络的网络类型优先级的网络，例如，基站2提供的4G网络的网络类型优先级高于基站1提供的3G网络。进一步的，终端比较基站2提供的4G网络的信号强度值与基站1提供的3G网络的信号强度值，若基站2提供的4G网络的信号强度值大于或等于基站1提供的3G网络的信号强度值，则终端将网络切换至基站2提供的4G网络。需要说明的，在切换至基站3提供的运营商2的4G网络时，终端首先将当前服务的数据业务卡切换从数据业务卡1至数据业务卡2，再进行网络的切换。Method 3: The terminal monitors the remaining available network traffic of the operator corresponding to the current service network. If the remaining available network traffic is lower than the first preset traffic threshold, the terminal searches the base station information list for a network type priority equal to or greater than that provided by base station 1. The network type priority of the current serving network, for example, the network type priority of the 4G network provided by the base station 2 is higher than that of the 3G network provided by the base station 1. Further, the terminal compares the signal strength value of the 4G network provided by the base station 2 with the signal strength value of the 3G network provided by the base station 1. If the signal strength value of the 4G network provided by the base station 2 is greater than or equal to the signal strength of the 3G network provided by the base station 1 value, the terminal switches the network to the 4G network provided by the base station 2. It should be noted that when switching to the 4G network of operator 2 provided by base station 3, the terminal first switches the currently serving data service card from data service card 1 to data service card 2, and then performs network switching.

根据上述三种可行的实现方式可知，本发明实施例的方案通过综合考虑网络的网络类型优先级、网络的信号强度和网络对应运营商的流量信息，来实现多卡终端的网络切换。从而更加有效的将终端切换至能够为用户提供更高质量网络服务或者更满足用户资费需求的可使用的网络，从而提供多卡终端对网络资源的利用率。According to the above three feasible implementation manners, the solution of the embodiment of the present invention realizes network switching of multi-card terminals by comprehensively considering the network type priority of the network, the signal strength of the network and the traffic information of the network corresponding operator. In this way, the terminal can be switched to an available network that can provide users with higher quality network services or better meet the user's tariff requirements, thereby improving the utilization rate of network resources by multi-card terminals.

图2为本发明实施例提供的终端设备的网络信息流程的示意图，如图2所示，该终端设备以手机为例，图中示出了一个典型的手机网络信息流程的示意图，手机网络硬件通过搜索附近基站信息，并将信息通过无线接口(Radio Interface Layer，简称：RIL)层返回到Androd Framework框架层，以储存基站及信号信息。用户在设置界面设置默认数据业务卡后，Framework层中的MsimTelephony(即图中的SIM框架接口)模块会匹配对应基站信息，然后选则合适的数据网络。其中RIL是系统平台手机与各厂商硬件的抽象层，MSimTelephony是各个芯片厂商对双卡手机提供的Android Framework框架层接口。FIG. 2 is a schematic diagram of a network information flow of a terminal device provided by an embodiment of the present invention. As shown in FIG. 2 , the terminal device takes a mobile phone as an example, and the figure shows a schematic diagram of a typical mobile phone network information flow. The mobile phone network hardware By searching for information about nearby base stations, and returning the information to the Androd Framework layer through the Radio Interface Layer (RIL) layer, the base station and signal information are stored. After the user sets the default data service card on the setting interface, the MsimTelephony (ie the SIM framework interface in the figure) module in the Framework layer will match the corresponding base station information, and then select the appropriate data network. Among them, RIL is the abstraction layer between the system platform mobile phone and the hardware of each manufacturer, and MSimTelephony is the Android Framework framework layer interface provided by each chip manufacturer for dual-card mobile phones.

If the terminal device includes a single data card, or three or more data cards, then The appropriate target network needs to be selected according to the network information parameters of each data card.

其中，每个数据卡的网络信息参数包括该卡的网络的剩余流量、网络的信号强度以及网络类型优先级中的至少两个参数。Wherein, the network information parameters of each data card include at least two parameters among the remaining traffic of the network of the card, the signal strength of the network, and the priority of the network type.

The example provides a specific implementation manner, that is, if the terminal detects new base station information, the terminal satisfies the network handover trigger condition; then the terminal in step S102 in the first embodiment above The network information parameters and the network information parameters of the second data card determine the target network to be switched, and the specific implementation steps include:

S201：所述终端获取所述新的基站信息对应的第一网络的网络类型。S201: The terminal acquires the network type of the first network corresponding to the new base station information.

S202：若所述终端判断出所述第一网络的网络类型优先级高于所述第一数据卡的当前网络的网络类型优先级，则获取所述第一网络的信号强度。S202: If the terminal determines that the network type priority of the first network is higher than the network type priority of the current network of the first data card, obtain the signal strength of the first network.

在本方案中，终端设备即所述终端检测到新的基站信息之后，判断该基站对应的第一网络的网络类型优先级是不是高于当前网络，或者是不是与该当前网络的优先级相同，如果是，则继续检测该第一网络的信号强度，否则放弃本次网络切换，待下次满足网络切换条件时，继续进行匹配。In this solution, after the terminal device, that is, the terminal, detects the new base station information, it determines whether the network type priority of the first network corresponding to the base station is higher than that of the current network, or whether it is the same as the priority of the current network. , if yes, continue to detect the signal strength of the first network, otherwise give up this network handover, and continue to perform matching when the network handover conditions are met next time.

S203：若所述终端确定出所述第一网络的信号强度与所述当前网络的信号强度的差值大于预设的信号强度阈值，则将所述第一网络确定为所述目标网络。S203: If the terminal determines that the difference between the signal strength of the first network and the signal strength of the current network is greater than a preset signal strength threshold, determine the first network as the target network.

在本步骤中，判断第一网络的信号强度是不是比当前网络的信号强度高，判断方式可以直接对比信号强度值，也可以按照上述的方式判断其间的差值是不是大于预设的信号强度阈值，只有在判断该第一网络的优先级不低于当前网络，并且信号强度比当前网络高的时候，才将该第一网络作为目标网络，实现网络切换。In this step, it is judged whether the signal strength of the first network is higher than the signal strength of the current network. The judgment method can be directly compared with the signal strength value, or it can be judged whether the difference between them is greater than the preset signal strength according to the above method. Threshold, only when it is judged that the priority of the first network is not lower than the current network and the signal strength is higher than the current network, the first network is used as the target network to implement network switching.

本方案具体实现中，也可以先判断第一网络的信号强度是不是高于当前网络，后判断两个网络的优先级的高低，本发明对于参数的对比和判断顺序不做限制。In the specific implementation of this solution, it is also possible to first judge whether the signal strength of the first network is higher than the current network, and then judge the priority of the two networks. The present invention does not limit the comparison of parameters and the judgment order.

本方案中新的基站信息可以是一个或者多个，如果检测到多个基站时候，则对每个新的网络按照上述方式判断优先级以及信号强度，选择出合适的目标网络，实现网络切换。In this solution, the new base station information can be one or more. If multiple base stations are detected, the priority and signal strength of each new network are determined according to the above method, and an appropriate target network is selected to realize network switching.

本方案提供的终端的网络切换方法，终端设备如果检测到新的基站信息，则触发网络切换的选择过程，需要判断该新的基站对应的第一网络的网络类型优先级以及信号强度，只有在该第一网络的优先级高于当前网络且信号强度比当前网络的信号强度时，才将该第一网络作为目标网络去实现切换，通过综合考虑网络类型优先级以及信号强度，保证切换后的网络性能优于当前网络。In the network handover method of the terminal provided by this solution, if the terminal device detects new base station information, it will trigger the selection process of network handover. It needs to judge the network type priority and signal strength of the first network corresponding to the new base station. When the priority of the first network is higher than that of the current network and the signal strength is higher than that of the current network, the first network is used as the target network to implement the handover. The network performance is better than the current network.

可选的若所述终端检测到新的基站信息，则所述终端满足网络切换触发条件，则终端可以根据新的网络的信号强度，网络类型优先级，剩余流量(或者已使用流量等流量使用情况)中的至少两个网络信息参数来实现步骤S102中的终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络。除了上述图4所示的实施例的方案，还包括以下几种实现方式：Optionally, if the terminal detects the new base station information, the terminal meets the network handover triggering conditions, and the terminal can use the signal strength of the new network, the priority of the network type, the remaining traffic (or the used traffic, etc.) The terminal determines the target network to be switched according to the network information parameters of the first data card and the network information parameters of the second data card in step S102. In addition to the solution of the embodiment shown in FIG. 4, the following implementations are also included:

第一种实现方式：The first implementation method:

终端获取所述新的基站信息对应的第一网络的网络类型；The terminal acquires the network type of the first network corresponding to the new base station information;

若所述终端判断出所述第一网络的网络类型优先级高于所述第一数据卡的当前网络的网络类型优先级，则获取所述第一网络的剩余流量；If the terminal determines that the network type priority of the first network is higher than the network type priority of the current network of the first data card, obtain the remaining traffic of the first network;

若所述终端确定出所述第一网络的剩余流量与所述当前网络的剩余流量的差值大于预设的流量阈值，则将所述第一网络确定为所述目标网络。If the terminal determines that the difference between the remaining traffic of the first network and the remaining traffic of the current network is greater than a preset traffic threshold, the terminal determines the first network as the target network.

该方案中，与上述类似的由终端设备检测到新的基站信息，则触发网络切换的选择过程，在选取目标网络的过程中，需要判断该新的基站对应的第一网络的网络类型优先级以及该第一网络的剩余流量或者已经使用的流量是否超限，只有在该第一网络的优先级高于当前网络且剩余流量较多时，才将该第一网络作为目标网络去实现切换，上述的方案提供了先判断网络类型优先级的方案，实际实现过程中，也可以先确定该第一网络的剩余流量，或者先确定第一网络的已使用流量，后判断优先级，对此本发明不做限制，通过综合考虑网络类型优先级以及剩余流量或已使用流量的情况，保证切换后的网络性能优于当前网络，并且不会出现流量不足产生费用，提高用户体验。In this solution, similar to the above, when new base station information is detected by the terminal device, the selection process of network handover is triggered. In the process of selecting the target network, it is necessary to judge the network type priority of the first network corresponding to the new base station. And whether the remaining traffic of the first network or the traffic that has been used exceeds the limit, only when the priority of the first network is higher than the current network and the remaining traffic is large, the first network is used as the target network to achieve switching, the above-mentioned The scheme provided by the method provides a scheme of first judging the priority of the network type. In the actual implementation process, the remaining traffic of the first network can also be determined first, or the used traffic of the first network can be determined first, and then the priority can be determined. There is no restriction. By comprehensively considering the network type priority and the remaining traffic or used traffic, it is guaranteed that the network performance after the switch is better than the current network, and there will be no shortage of traffic to generate fees, improving user experience.

第二种实现方式：The second way to implement:

所述终端获取所述新的基站信息对应的第一网络的信号强度；acquiring, by the terminal, the signal strength of the first network corresponding to the new base station information;

若所述终端获取所述第一网络的信号强度与所述第一数据卡的当前网络的信号强度的差值大于预设的信号强度阈值，则获取所述第一网络的剩余流量；If the difference between the signal strength of the first network acquired by the terminal and the signal strength of the current network of the first data card is greater than a preset signal strength threshold, the terminal acquires the remaining traffic of the first network;

若所述终端确定出所述第一网络的剩余流量与所述当前网络的剩余流量的差值大于预设的流量阈值，则将所述第一网络确定为所述目标网络。If the terminal determines that the difference between the remaining traffic of the first network and the remaining traffic of the current network is greater than a preset traffic threshold, the terminal determines the first network as the target network.

在该方案中，与上述类似的依然由终端设备检测到新的基站信息，则触发网络切换的选择过程，在选取目标网络的过程中，只需要考虑新的基站信息对应的第一网络的信号强度以及该第一网络的剩余流量或者已经使用的流量是否超限，只有在该第一网络的信号强度高于当前网络且剩余流量较多时，才将该第一网络作为目标网络去实现切换，上述的方案提供了先判断信号强度的方案，实际实现过程中，也可以先确定该第一网络的剩余流量，或者先确定第一网络的已使用流量，后判断第一网络和当前网络的信号强度，对此本发明不做限制，通过综合考虑网络类型优先级以及网络的信号强度的情况，保证切换后的网络性能优于当前网络，提高用户体验和网络切换的准确度。In this solution, similar to the above, the terminal device still detects the new base station information, and triggers the selection process of network handover. In the process of selecting the target network, only the signal of the first network corresponding to the new base station information needs to be considered. strength and whether the remaining traffic of the first network or the traffic that has been used exceeds the limit. Only when the signal strength of the first network is higher than the current network and the remaining traffic is large, the first network is used as the target network to achieve handover, The above solution provides a solution of first judging the signal strength. In the actual implementation process, the remaining traffic of the first network can also be determined first, or the used traffic of the first network can be determined first, and then the signals of the first network and the current network can be determined. The present invention does not limit the strength of the network. By comprehensively considering the network type priority and the signal strength of the network, it is ensured that the network performance after handover is better than the current network, and the user experience and the accuracy of network handover are improved.

图5为本发明实施例提供的终端的网络切换方法实施例三的流程图，如图5所示，在上述实施例一的基础上，以终端检测到当前网络的信号强度低于预设的信号强度门限触发网络切换，本实施例提供一种具体的实现方式，即若所述终端检测到所述第一数据卡的当前网络的信号强度低于预设的信号强度门限，则所述终端满足网络切换触发条件；则上述实施例一中步骤S102中的所述终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络，具体实现步骤包括：FIG. 5 is a flowchart of Embodiment 3 of a network switching method for a terminal according to an embodiment of the present invention. As shown in FIG. 5 , on the basis of the foregoing Embodiment 1, the signal strength of the current network detected by the terminal is lower than a preset value. The signal strength threshold triggers network switching. This embodiment provides a specific implementation manner, that is, if the terminal detects that the signal strength of the current network of the first data card is lower than the preset signal strength threshold, the terminal The network switching trigger condition is met; then the terminal in step S102 in the first embodiment above determines the target network to be switched according to the network information parameters of the first data card and the network information parameters of the second data card, and the specific implementation steps include:

S301：所述终端从存储的基站信息列表中，获取至少一个网络类型优先级不低于所述当前网络的第二网络。S301: The terminal acquires, from the stored base station information list, at least one second network whose network type priority is not lower than the current network.

在本实施例中，终端设备检测到当前的信号强度低于预设的信号强度门限时候，从本地存储基站信息列表中查找新的网络，该新的网络的网络类型优先级高于或者所述当前网络的网络类型优先级，或者与当前网络的网络类型优先级相同。In this embodiment, when the terminal device detects that the current signal strength is lower than the preset signal strength threshold, it searches for a new network from the locally stored base station information list, and the network type priority of the new network is higher than or above The network type priority of the current network, or the same as the network type priority of the current network.

S302：所述终端获取每个第二网络的剩余流量。S302: The terminal acquires the remaining traffic of each second network.

S303：所述终端根据每个第二网络的剩余流量，根据预设的最优流量套餐判定条件，从所述至少一个第二网络中选择出最优流量套餐的一个第二网络作为所述目标网络。S303: The terminal selects, from the at least one second network, a second network with an optimal flow package as the target according to the remaining flow of each second network and according to preset optimal flow package determination conditions network.

在本实施例中，获取了优先级不低于当前网络的一个或多个第二网络之后，检测每个第二网络的剩余流量，或者已使用流量，选择出剩余流量高于预设的门限的网络，或者剩余流量最多的网络，或者已使用流量未超过设置的限制值的网络作为目标网络，进行网络切换。In this embodiment, after obtaining one or more second networks whose priorities are not lower than the current network, the remaining traffic of each second network, or the used traffic, is detected, and the remaining traffic is selected to be higher than a preset threshold network, or the network with the most remaining traffic, or the network whose traffic does not exceed the set limit value has been used as the target network to perform network switching.

在本实施例中，可以优先判断网络类型优先级，也可以先判断剩余流量，对此不做限制。In this embodiment, the priority of the network type may be determined first, and the remaining traffic may also be determined first, which is not limited.

本实施例提供的终端的网络切换方法，触发网络切换的功能的条件的是检测到当前网络的信号强度较差，例如：信号强度小于预设信号强度门限。为避免用户的数据业务或者通话质量受到影响，则可以根据其他的参数结合起来选择新的目标网络进行切换，具体实现中，可以从该终端设备中存储的多个基站信息中选择，这里的基站包括多种网络制式的站点，首先选择网络类型优先级高于或者跟当前网络相同的多个第二网络，然后分别检测每个第二网络的剩余流量是不是满足设定的条件，或者检测每个第二网络的已使用流量是否超过限制值，或者可以根据信号强度的排序，根据网络类型优先级以及流量使用情况选择合适的目标网络进行网络切换，可有效提供网络切换的准确度。In the network switching method of the terminal provided in this embodiment, the condition for triggering the function of network switching is to detect that the signal strength of the current network is poor, for example, the signal strength is less than a preset signal strength threshold. In order to prevent the user's data service or call quality from being affected, a new target network can be selected for handover according to other parameters. For sites with multiple network standards, first select multiple second networks with a higher priority or the same network type as the current network, and then check whether the remaining traffic of each second network meets the set conditions, or check whether each Whether the used traffic of the second network exceeds the limit value, or according to the sorting of signal strength, network type priority and traffic usage, the appropriate target network can be selected for network switching, which can effectively improve the accuracy of network switching.

可选的若所述终端检测到当前网络的信号强度低于预设信号强度门限，则所述终端满足网络切换触发条件，则终端可以根据新的网络的信号强度，网络类型优先级，剩余流量(或者已使用流量等流量使用情况)中的至少两个网络信息参数来实现步骤S102中的终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络。除了上述图5所示的实施例的方案，还包括以下几种实现方式：Optionally, if the terminal detects that the signal strength of the current network is lower than the preset signal strength threshold, and the terminal satisfies the network handover trigger condition, the terminal can determine the signal strength of the new network, the priority of the network type, and the remaining traffic according to the signal strength of the new network. At least two network information parameters in (or traffic usage conditions such as traffic have been used) to implement step S102. The terminal determines the target network to be switched according to the network information parameters of the first data card and the network information parameters of the second data card. In addition to the solution of the embodiment shown in FIG. 5, the following implementations are also included:

第一种实现方式：The first implementation method:

所述终端从存储的基站信息列表中，获取至少一个信号强度大于所述信号强度门限的第二网络；The terminal acquires at least one second network whose signal strength is greater than the signal strength threshold from the stored base station information list;

所述终端获取每个第二网络的剩余流量；obtaining, by the terminal, the remaining traffic of each second network;

所述终端根据每个第二网络的剩余流量，根据预设的最优流量套餐判定条件，从所述至少一个第二网络中选择出最优流量套餐的一个第二网络作为所述目标网络。The terminal selects a second network with an optimal flow package from the at least one second network as the target network according to the remaining flow of each second network and according to preset optimal flow package determination conditions.

在本实现方式中，与上述方案类似的，依然是由当前网络的信号强度低于门限值触发网络切换动作，终端设备从存储的基站信息列表中选择信号强度大于门限值的多个第二网络，然后根据该些第二网络的流量使用情况(包括剩余流量或者已使用流量)或者根据网络类型优先级，选择流量套餐合理，或者信号强度和网络优先级高于当前网络的目标网络进行网络切换，有效提高网络切换的准确度，保证切换后的网络性能优于当前网络。In this implementation manner, similar to the above solution, the network handover action is still triggered when the signal strength of the current network is lower than the threshold value, and the terminal device selects from the stored base station information list a plurality of firsts whose signal strength is greater than the threshold value. Second network, and then according to the traffic usage of these second networks (including remaining traffic or used traffic) or according to the network type priority, select a reasonable traffic package, or the signal strength and network priority are higher than the target network of the current network. Network switching can effectively improve the accuracy of network switching and ensure that the network performance after switching is better than the current network.

另外，在具体实现中，上述的剩余流量的判断，或者信号强度的对比，或者网络优先级的选择执行顺序不做限制，可以根据实际情况进行选择。In addition, in the specific implementation, the judgment of the remaining traffic, the comparison of the signal strength, or the selection and execution order of the network priority are not limited, and can be selected according to the actual situation.

第二种实现方式：The second way to implement:

所述终端从存储的基站信息列表中，获取至少一个剩余流量大于预设剩余流量门限的第二网络；The terminal obtains, from the stored base station information list, at least one second network whose remaining traffic is greater than a preset remaining traffic threshold;

所述终端获取每个第二网络的信号强度；obtaining, by the terminal, the signal strength of each second network;

所述终端根据每个第二网络的信号强度，从所述至少一个第二网络中选择出信号强度最优的一个第二网络作为所述目标网络。The terminal selects, from the at least one second network, one second network with the best signal strength as the target network according to the signal strength of each second network.

与上述两个方案类似，在本实现方式中，依然由当前网络信号强度低于门限值来触发网络切换的动作，终端设备从存储的基站信息列表中，选择出剩余流量较多，即已使用的流量较少，网络流量比较合理的多个第二网络，然后根据每个第二网络的优先级或者信号强度，优先选择信号强度较强或者网络类型优先级的网络作为目标网络，完成网络切换，该切换后的网络性能优于当前网络，且在实现过程中对于先判断哪个参数，后判断哪个参数本发明不做限制。Similar to the above two solutions, in this implementation manner, the network handover action is still triggered by the current network signal strength lower than the threshold value, and the terminal device selects from the stored base station information list that there is more remaining traffic, that is, it has been Use multiple second networks with less traffic and reasonable network traffic, and then select the network with stronger signal strength or network type priority as the target network according to the priority or signal strength of each second network to complete the network. handover, the network performance after the handover is better than the current network, and the present invention does not limit which parameter is judged first and which parameter is judged later in the implementation process.

图6为本发明实施例提供的终端的网络切换方法实施例四的流程图，如图6所示，在上述实施例一的基础上，以终端检测到当前网络的剩余流量少于预设剩余流量门限，或者已使用流量超过预设的使用流量门限时触发网络切换，本实施例提供一种具体的实现方式，即若所述终端检测到所述第一数据卡的当前网络的剩余流量低于预设的剩余流量门限，则所述终端满足网络切换触发条件；则上述实施例一中步骤S102中的所述终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络，具体实现步骤包括：FIG. 6 is a flowchart of Embodiment 4 of a network switching method for a terminal according to an embodiment of the present invention. As shown in FIG. 6 , on the basis of Embodiment 1 above, the terminal detects that the remaining traffic of the current network is less than the preset remaining traffic. The traffic threshold, or the network switching is triggered when the used traffic exceeds the preset used traffic threshold. This embodiment provides a specific implementation method, that is, if the terminal detects that the remaining traffic of the current network of the first data card is low is within the preset remaining traffic threshold, the terminal satisfies the network handover triggering condition; then the terminal in step S102 in the first embodiment above determines the network information parameter of the first data card and the network information parameter of the second data card The target network that needs to be switched. The specific implementation steps include:

S401：所述终端从存储的基站信息列表中，获取至少一个网络类型优先级不低于所述当前网络的第二网络。S401: The terminal acquires, from the stored base station information list, at least one second network whose network type priority is not lower than the current network.

与上述实施例二类似的，终端设备从本地存储的基站信息列表中，选择可以连接到的网络类型优先级高于或等于当前网络的网络类型优先级的一个或者多个第二网络。Similar to Embodiment 2 above, the terminal device selects one or more second networks that can connect to a network type priority higher than or equal to the network type priority of the current network from the locally stored base station information list.

S402：所述终端获取每个第二网络的剩余流量。S402: The terminal acquires the remaining traffic of each second network.

S403：所述终端根据每个第二网络的剩余流量，根据预设的最优流量套餐判定条件，从所述至少一个第二网络中选择出最优流量套餐的一个第二网络作为所述目标网络。S403: The terminal selects, from the at least one second network, a second network with an optimal flow package as the target according to the remaining flow of each second network and according to preset optimal flow package determination conditions network.

然后该终端设备从监测每个第二网络的已使用流量或者剩余流量，根据预设的最优流量套餐判定条件，从该些第二网络中选择出流量套餐最合理的一个作为目标网络，实现网络切换。Then, the terminal device monitors the used traffic or remaining traffic of each second network, and selects the most reasonable traffic package from the second networks as the target network according to the preset optimal traffic package determination conditions, so as to realize network switch.

其中，该最优流量套餐判定条件可以包括：剩余流量最多，或者已使用流量最少等。Wherein, the condition for determining the optimal traffic package may include: the remaining traffic is the most, or the used traffic is the least, and the like.

在本方案中，该方案中是由当前使用的网络制式下的剩余流量不足来触发网络切换，为避免超出流量套餐为用户带来不必要的费用，本方案终端设备从基站信息列表中获取网络优先级比当前网络高或者相同的多个第二网络，然后根据每个第二网络的信号强度或者剩余流量即流量使用情况来选择目标网络，完成网络切换，在实现过程中，也可以优先考虑剩余流量或者网络信号强度，再考虑网络类型优先级的高低，可以根据实际情况进行设置，对此不做限制。In this solution, the network switching is triggered by insufficient remaining traffic under the currently used network standard. In order to avoid unnecessary costs for users due to exceeding the traffic plan, the terminal device in this solution obtains the network from the base station information list. Multiple second networks with a higher priority or the same priority than the current network, and then select the target network according to the signal strength of each second network or the remaining traffic, that is, the traffic usage, to complete the network switch. In the implementation process, you can also give priority to The remaining traffic or network signal strength, and then considering the priority of the network type, can be set according to the actual situation, and there is no restriction on this.

可选的若所述终端检测到当前网络的剩余流量低于预设剩余流量门限，则所述终端满足网络切换触发条件，则终端可以根据新的网络的信号强度，网络类型优先级，剩余流量(或者已使用流量等流量使用情况)中的至少两个网络信息参数来实现步骤S102中的终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络。除了上述图5所示的实施例的方案，还包括以下几种实现方式：Optionally, if the terminal detects that the remaining traffic of the current network is lower than the preset remaining traffic threshold, and the terminal satisfies the network handover trigger condition, the terminal can determine the remaining traffic according to the signal strength of the new network, the priority of the network type, and the remaining traffic. At least two network information parameters in (or traffic usage conditions such as traffic have been used) to implement step S102. The terminal determines the target network to be switched according to the network information parameters of the first data card and the network information parameters of the second data card. In addition to the solution of the embodiment shown in FIG. 5, the following implementations are also included:

第一种实现方式：The first implementation method:

所述终端从存储的基站信息列表中，获取至少一个信号强度大于所述信号强度门限的第二网络；The terminal acquires at least one second network whose signal strength is greater than the signal strength threshold from the stored base station information list;

所述终端获取每个第二网络的剩余流量；obtaining, by the terminal, the remaining traffic of each second network;

所述终端根据每个第二网络的剩余流量，根据预设的最优流量套餐判定条件，从所述至少一个第二网络中选择出最优流量套餐的一个第二网络作为所述目标网络。The terminal selects a second network with an optimal flow package from the at least one second network as the target network according to the remaining flow of each second network and according to preset optimal flow package determination conditions.

可选的，也可以先根据剩余流量选择出满足最优流量套餐的多个网络，然后判断该些网络的信号强度，按照信号强度由高到低的顺序来选择合适的目标网络，进行网络切换。Optionally, you can first select multiple networks that satisfy the optimal traffic package according to the remaining traffic, then judge the signal strength of these networks, select the appropriate target network in the order of signal strength from high to low, and perform network switching. .

与上述方案类似，该方案中同样的由剩余流量不足来触发网络切换动作，终端设备根据网络信号强度和每个网络的流量使用情况，或者根据网络信号强度和网络类型优先级，从基站信息列表中选择网络状态和剩余流量都比较好的目标网络完成网络切换，提高网络切换的准确度和用户体验。Similar to the above scheme, in this scheme, the network switching action is also triggered by insufficient remaining traffic. The terminal device selects the information from the base station information list according to the network signal strength and the traffic usage of each network, or according to the network signal strength and network type priority. Select the target network with better network status and remaining traffic to complete network switching, improve the accuracy of network switching and user experience.

第二种实现方式：The second way to implement:

所述终端从存储的基站信息列表中，获取至少一个剩余流量大于预设剩余流量门限的第二网络；The terminal obtains, from the stored base station information list, at least one second network whose remaining traffic is greater than a preset remaining traffic threshold;

所述终端获取每个第二网络的信号强度；obtaining, by the terminal, the signal strength of each second network;

所述终端根据每个第二网络的信号强度，从所述至少一个第二网络中选择出信号强度最优的一个第二网络作为所述目标网络。The terminal selects, from the at least one second network, one second network with the best signal strength as the target network according to the signal strength of each second network.

本方案中，也是用过剩余流量低于预设门限来作为网络切换的触发条件，然后根据基站信息列表中存储的多个网络的信息，根据剩余流量的状况和信号强度，或者可以根据剩余流量的状况和网络类型优先级的，选择出性能较好的目标网络进行网络切换，综合考虑多个参数选择性能和剩余流量合理的目标网络，提高网络切换的准确度。In this solution, the remaining traffic below the preset threshold is also used as the trigger condition for network handover, and then according to the information of multiple networks stored in the base station information list, according to the status and signal strength of the remaining traffic, or according to the remaining traffic According to the status and network type priority, the target network with better performance is selected for network handover, and the target network with reasonable performance and remaining traffic is selected comprehensively considering multiple parameters, so as to improve the accuracy of network handover.

在上述的多种方式中，均是从各卡的每个网络的信号强度、每个网络剩余流量以及每个网络的网络类型优先级中的任意两个参数作为选择新的目标网络的，并且对于选择出的任意两个参数，在具体实现过程中判断的顺序不限制，只要能够选择出性能优于当前网络的目标网络即可。In the above-mentioned various manners, the new target network is selected from any two parameters of the signal strength of each network of each card, the remaining traffic of each network, and the network type priority of each network, and For any two parameters selected, the order of judgment in the specific implementation process is not limited, as long as a target network with better performance than the current network can be selected.

在上述图3至图6示出的实施例中，均是采用在触发了网络切换动作之后，选择两种参数进行目标网络的选择，能够在一定程度上提高网络切换的准确度，优选的，终端设备根据各卡的每个网络的信号强度、每个网络剩余流量以及每个网络的网络类型优先级三种参数进行目标网络的选择一，以进一步提高网络切换的准确度，提高用户体验。下面分别对每种实现方式进行说明。In the above-mentioned embodiments shown in FIGS. 3 to 6 , after the network switching action is triggered, two parameters are selected to select the target network, which can improve the accuracy of network switching to a certain extent. Preferably, The terminal device selects the target network according to the three parameters of the signal strength of each network of each card, the remaining traffic of each network and the network type priority of each network, so as to further improve the accuracy of network switching and improve user experience. Each implementation is described below.

S502：若所述终端判断出所述第一网络的网络类型优先级高于所述第一数据卡的当前网络的网络类型优先级，则获取所述第一网络的信号强度。S502: If the terminal determines that the network type priority of the first network is higher than the network type priority of the current network of the first data card, obtain the signal strength of the first network.

在本步骤中，终端检测到新的基站信息后，检测获取该新的基站对应的第一网络的网络类型，根据预先配置的网络类型优先级顺序或者默认的网络类型优先级，检测该第一网络的优先级是不是高于当前网络，或者与当前网络相同，如果该第一网络的网络类型优先级低于当前网络，则放弃本次切换过程，即保证不要切换至性能不好的网络。In this step, after detecting the new base station information, the terminal detects and obtains the network type of the first network corresponding to the new base station, and detects the first network type according to the pre-configured priority order of network types or the default network type priority. Whether the priority of the network is higher than the current network, or the same as the current network, if the network type priority of the first network is lower than the current network, the handover process is abandoned, that is, it is guaranteed not to switch to a network with poor performance.

在检测到优先级符合条件之后，获取该第一网络的信号强度，进一步对信号强度进行对比，保证切换后的网络的信号质量优于当前网络。After it is detected that the priority meets the conditions, the signal strength of the first network is obtained, and the signal strength is further compared to ensure that the signal quality of the switched network is better than that of the current network.

S503：若所述终端确定出所述第一网络的信号强度与所述当前网络的信号强度的差值大于预设的信号强度阈值，则获取所述第一网络的剩余流量和所述当前网络的剩余流量。S503: If the terminal determines that the difference between the signal strength of the first network and the signal strength of the current network is greater than a preset signal strength threshold, obtain the remaining traffic of the first network and the current network remaining flow.

在本步骤中，如果检测到第一网络的信号强度低于当前网络的信号强度，则放弃本次网络切换过程。In this step, if it is detected that the signal strength of the first network is lower than that of the current network, the current network switching process is abandoned.

在判断对信号强度进行对比的过程中，可以直接对比第一网络和当前网络的信号强度的大小，也可以判断其间的差值是否大于预设的信号强度阈值，在满足了信号强度的条件之后，最后检测第一网络的剩余流量，判断剩余流量是否能够满足要求。In the process of judging and comparing the signal strengths, the magnitudes of the signal strengths of the first network and the current network can be directly compared, and it can also be judged whether the difference between them is greater than a preset signal strength threshold, after the signal strength conditions are met. , and finally detect the remaining traffic of the first network, and determine whether the remaining traffic can meet the requirements.

S504：若所述第一网络的剩余流量与所述当前网络的剩余流量的差值大于预设的流量阈值，则将所述第一网络确定为所述目标网络。S504: If the difference between the remaining traffic of the first network and the remaining traffic of the current network is greater than a preset traffic threshold, determine the first network as the target network.

在本步骤中，若第一网络的流量不足则结束本次网络切换，避免用户因使用切换后的网络产生不必要的费用，判断第一网络的剩余流量是否满足条件的方式可以是：直接对比第一网络的剩余流量和当前网络的剩余流量，若第一网络的剩余流量比当前网络的剩余流量多，则满足；或者按照上述的判断第一网络的剩余流量与当前网络的剩余流量的差值是否大于设置的阈值；或者也可以直接检测已使用流量，判断以使用流量是否超过了预设的门限值，本发明对于具的判断方式不做限制。In this step, if the traffic of the first network is insufficient, the network switching is terminated, so as to avoid unnecessary charges incurred by the user due to the use of the switched network, and the method of judging whether the remaining traffic of the first network meets the conditions may be: direct comparison The residual traffic of the first network and the residual traffic of the current network, if the residual traffic of the first network is more than the residual traffic of the current network, it is satisfied; or the difference between the residual traffic of the first network and the residual traffic of the current network is judged as described above. Whether the value is greater than the set threshold; or the used flow can also be directly detected to judge whether the used flow exceeds the preset threshold value, and the present invention does not limit the judgment method of the device.

Compare the network types, according to the preset network type priority, for example: 4G>3G>2G, if B is better than A, such as A is 3G, B is 4G, then the network performance of the newly added base station is better than A, go to the step 3, otherwise go to step 4.

3、获取A与B网络信号的信号强度S，对比信号强度SA和SB，若SB-SA>阈值，进入步骤5，否则进入步骤4.3. Obtain the signal strength S of the A and B network signals, compare the signal strength SA and SB, if SB-SA>threshold, go to step 5, otherwise go to step 4.

4、结束本次匹配过程，放弃本次网络切换过程。4. End the matching process and abandon the network switching process.

In actual implementation, the judgment order of the above three parameters is not limited in the present invention, and may The situation is set randomly, that is, there are six implementations generated by the arrangement and combination of three parameters, all of which can realize the selection of the above target network.

The target network is switched, the target network can be the network standard of the first data card, or it can be the network of other data cards installed in the terminal device, such as the second data card, in this way, the switching is effectively guaranteed. The later network performance is better, and no additional costs are incurred due to data traffic, which effectively improves the accuracy of network switching and improves user experience.

图8为本发明实施例提供的终端的网络切换方法实施例六的流程图，如图8所示该方案的执行主体为终端设备，即上述图1和图2中的终端，例如：手机、平板电脑等可通过数据卡实现数据业务的设备，在如图3所示的实施例的基础上，当终端检测到所述第一数据卡的当前网络的信号强度低于预设的信号强度门限，则确定终端满足网络切换触发条件，需要进行网络切换的匹配过程，则步骤102中的终端根据第一数据卡的网络信息参数和第二数据卡的网络信息参数确定需要切换的目标网络，具体是按步骤为：FIG. 8 is a flowchart of Embodiment 6 of a network switching method for a terminal provided by an embodiment of the present invention. As shown in FIG. 8 , the execution subject of the solution is a terminal device, that is, the terminal in the above-mentioned FIG. 1 and FIG. 2 , such as a mobile phone, A device that can implement data services through a data card, such as a tablet computer, on the basis of the embodiment shown in FIG. 3 , when the terminal detects that the signal strength of the current network of the first data card is lower than the preset signal strength threshold , then it is determined that the terminal satisfies the network handover trigger condition and needs to perform the matching process of network handover, then the terminal in step 102 determines the target network to be handed over according to the network information parameters of the first data card and the network information parameters of the second data card. The steps are:

S601：所述终端从存储的基站信息列表中，获取至少一个网络类型优先级不低于所述当前网络的第二网络。S601: The terminal obtains, from the stored base station information list, at least one second network whose network type priority is not lower than that of the current network.

In fact, in the specific implementation process, which parameter is judged first is not limited, that is, there are six implementation methods generated by the arrangement and combination of three parameters. The selection of the target network described above can be achieved.

进一步的，该终端包括：处理模块控制的网络匹配单元、收发单元、流量管理单元；其中，收发单元的功能可以通过无线接口(Radio Interface Layer，简称：RIL)层实现：终端的射频单元通过搜索附近基站，获得每个基站的网络的信号强度值、每个基站的网络的网络类型，将这些信息通过RIL层返回到安卓框架(Androd Framework)层，并将上述网络信息列表储存在安卓框架层。Further, the terminal includes: a network matching unit, a transceiver unit, and a traffic management unit controlled by the processing module; wherein, the function of the transceiver unit can be realized through a radio interface (Radio Interface Layer, RIL for short) layer: the radio frequency unit of the terminal searches for Nearby base stations, obtain the signal strength value of the network of each base station and the network type of the network of each base station, return this information to the Android framework layer through the RIL layer, and store the above network information list in the Android framework layer. .
