Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Example one

Fig. 3 is a first schematic flow chart illustrating an implementation of a wireless handover method according to an embodiment of the present invention, as shown in fig. 3, in an embodiment of the present invention, a method for a terminal to perform wireless handover may include the following steps:

step 101, when accessing a first wireless network connected with a first radio frequency module through the first radio frequency module, detecting a first throughput of the first wireless network and a second throughput of a second wireless network connected with a second radio frequency module according to a first preset time interval; the first wireless network is one of two connected wireless networks which is in use; the second wireless network is an unused one of the two wireless networks.

In an embodiment of the present invention, when the terminal accesses to the first wireless network corresponding to the first radio frequency module through the first radio frequency module, the terminal may detect a throughput of the first wireless network, that is, a first throughput, according to a preset first preset time interval, and meanwhile, the terminal may also detect a throughput of a second wireless network connected to the second radio frequency module, that is, a second throughput.

It should be noted that, in the embodiment of the present invention, the terminal may be a terminal configured with two radio frequency modules, and the terminal may be a variety of intelligent terminals with a wireless function, for example, the terminal may be a mobile phone, a smart camera, a tablet computer, and the like.

Further, in an embodiment of the present invention, the terminal may establish a connection with the first wireless network and the second wireless network through the two wireless radio frequency modules, that is, the first radio frequency module and the second radio frequency module. Specifically, in the embodiment of the present invention, the first wireless network is one of two connected wireless networks that is in use; the second wireless network is an unused one of the two wireless networks.

It should be noted that, in an embodiment of the present invention, before the terminal accesses the first wireless network through the first radio frequency module, the first radio frequency module already establishes a connection with the first wireless network, and meanwhile, the second radio frequency module already establishes a connection with the second wireless network.

Further, in the embodiment of the present invention, the terminal may preset the first preset time interval, for example, the terminal may preset the time interval to be 5min, and then the terminal may detect the first throughput and the second throughput every 5min after accessing to the first wireless network, so as to avoid a problem of excessive power consumption of the terminal caused by performing real-time detection on the first wireless network and the second wireless network.

It should be noted that, in the embodiment of the present invention, since the throughput for characterizing the amount of data successfully transmitted per unit time is more representative of the actual data transmission capability of the wireless network, the embodiment of the present invention tends to use the throughput of the wireless network to represent the data transmission performance of a wireless network.

And 102, when the first throughput is smaller than the second throughput, detecting the first real-time throughput of the first wireless network and the second real-time throughput of the second wireless network according to a second preset time interval.

In an embodiment of the present invention, when the terminal accesses to the first wireless network corresponding to the first radio frequency module through the first radio frequency module, after detecting a first throughput of the first wireless network and a second throughput of the second wireless network corresponding to the second radio frequency module according to a first preset time interval, if the first throughput is smaller than the second throughput, the terminal may detect a first real-time throughput of the first wireless network and a second real-time throughput of the second wireless network according to a second preset time interval.

It should be noted that, in the embodiment of the present invention, the first preset time interval is greater than the second preset time interval. For example, the terminal may set the time interval to 5s in advance, and after determining that the first throughput is smaller than the second throughput, the terminal may detect the first real-time throughput and the second real-time throughput every 5 s.

Further, in an embodiment of the present invention, after the terminal detects the first throughput and the second throughput at the first preset time interval, the terminal may compare the first throughput with the second throughput, and if the first throughput is smaller than the second throughput, the terminal may start to detect the throughputs of the first wireless network and the second wireless network in real time, so as to obtain the first real-time throughput and the second real-time throughput.

Further, in an embodiment of the present invention, after the terminal detects the first throughput and the second throughput, if the first throughput is less than the second throughput, that is, the actual transmission capability of the first wireless network is lower than the actual transmission capability of the second wireless network, the terminal does not directly access the handover to the second wireless network, but detects the real-time throughputs of the first wireless network and the second wireless network, and further determines whether the handover access to the second wireless network is needed.

And 103, judging whether a preset wireless network switching condition is met or not according to the first real-time throughput and the second real-time throughput.

In an embodiment of the present invention, if the first throughput is smaller than the second throughput, the terminal may determine whether a predetermined wireless network handover condition is satisfied based on the first real-time throughput and the second real-time throughput after detecting the first real-time throughput of the first wireless network and the second real-time throughput of the second wireless network at a second predetermined time interval.

Further, in an embodiment of the present invention, after detecting the real-time throughputs of the first wireless network and the second wireless network and obtaining the first real-time throughput and the second real-time throughput, the terminal may determine whether to switch to the second wireless network according to the first real-time throughput and the second real-time throughput, instead of directly switching to the second wireless network after determining that the first throughput is less than the second throughput, so as to overcome a defect of power consumption increase caused by frequent switching to the wireless network.

And 104, when the preset wireless network switching condition is met, accessing to a second wireless network through a second radio frequency module.

In an embodiment of the present invention, after the terminal determines whether a preset wireless network switching condition is satisfied according to the first real-time throughput and the second real-time throughput, if it is determined that the preset wireless network switching condition is satisfied, the terminal may perform a wireless switching process, that is, access to the second wireless network through the second radio frequency module.

Further, in an embodiment of the present invention, if the terminal determines that the preset wireless network switching condition is satisfied according to the first real-time throughput and the second real-time throughput, the terminal may directly switch the first wireless network to the second wireless network.

step 105, acquiring a plurality of standby wireless networks.

In an embodiment of the present invention, before the terminal accesses the first wireless network corresponding to the first radio frequency module through the first radio frequency module, the terminal may first acquire a plurality of standby wireless networks.

In the embodiment of the present invention, when the terminal is located in a specific location having a plurality of fixed wireless networks, the terminal may first acquire a plurality of standby wireless networks in the location. For example, when the terminal is in a mall, 4 fixed wireless networks, namely, a mall wireless network 1, a mall wireless network 2, a mall wireless network 3 and a mall wireless network 4 in the mall can be obtained.

Step 106, detecting a plurality of throughputs corresponding to a plurality of standby wireless networks; where one standby wireless network corresponds to one throughput.

In an embodiment of the present invention, after acquiring the plurality of standby wireless networks, the terminal may first detect a plurality of throughputs corresponding to the plurality of standby wireless networks, respectively. Specifically, one standby wireless network corresponds to one throughput.

Further, in an embodiment of the present invention, after detecting a plurality of throughputs of the plurality of standby wireless networks, the terminal compares the plurality of throughputs to determine actual data transmission capabilities of the plurality of wireless networks. For example, if the throughput 2 is greater than the throughput 1, it can be shown that the actual data transmission capability of the mall wireless network 2 is stronger than the actual data transmission capability of the mall wireless network 1.

Specifically, in the embodiment of the present invention, the terminal may sort the plurality of standby wireless networks in order from high throughput to low throughput to obtain a sorted standby wireless network list. Fig. 5 is a schematic diagram of a sorted standby wireless network list in an embodiment of the present invention, as shown in fig. 5, in the embodiment of the present invention, the terminal obtains throughput 1 of the mall wireless network 1, throughput 2 of the mall wireless network 2, throughput 3 of the mall wireless network 3, and throughput 4 of the mall wireless network 4, where the throughputs are throughput 3, throughput 2, throughput 1, and throughput 4 in the descending order, and then in the sorted standby wireless network list, the order of the standby wireless network is the mall wireless network 3, the mall wireless network 2, the mall wireless network 1, and the mall wireless network 4 in sequence.

Step 108, respectively determining two standby wireless networks with the maximum throughput in the standby wireless network list as a first wireless network and a second wireless network; and the throughput corresponding to the first wireless network is greater than the throughput corresponding to the second wireless network.

In an embodiment of the present invention, after the terminal sorts the plurality of standby wireless networks in order of throughput from high to low to obtain a sorted standby wireless network list, two standby wireless networks with the highest throughput in the standby wireless network list may be respectively determined as the first wireless network and the second wireless network; specifically, in the embodiment of the present invention, the throughput corresponding to the first wireless network is greater than the throughput corresponding to the second wireless network.

In an embodiment of the present invention, after the terminal sorts the plurality of standby wireless networks according to throughput and obtains the list of standby wireless networks, the terminal may determine a standby wireless network with a relatively large throughput among the plurality of standby wireless networks as the first wireless network and determine a standby wireless network with a second lowest throughput among the plurality of standby wireless networks as the second wireless network. That is, the terminal may determine the first standby wireless network and the second standby wireless network in the standby wireless network list as the first wireless network and the second wireless network, respectively.

Further, in an embodiment of the present invention, based on the above fig. 5, the terminal may determine the mall wireless network 3 as the first wireless network and determine the mall wireless network 2 as the second wireless network.

Fig. 6 is a third schematic flow chart of an implementation of a wireless handover method according to an embodiment of the present invention, as shown in fig. 6, in an embodiment of the present invention, after the terminal determines two standby wireless networks with the maximum throughput in the standby wireless network list as the first wireless network and the second wireless network, respectively, that is, after step 108, the method for the terminal to perform wireless handover may further include the following steps:

step 109, connecting the first radio frequency module to a first wireless network, and connecting the second radio frequency module to a second wireless network.

step 103a, performing proportional operation on the first real-time throughput and the second real-time throughput to obtain a ratio result of the first real-time throughput and the second real-time throughput.

In an embodiment of the present invention, if the first throughput is smaller than the second throughput, after detecting the first real-time throughput of the first wireless network and the second real-time throughput of the second wireless network, the terminal may perform a proportional operation on the first real-time throughput and the second real-time throughput, and then obtain a ratio result of the first real-time throughput and the second real-time throughput.

And 103b, judging that the preset wireless network switching condition is met when the ratio result is smaller than the preset ratio threshold.

In an embodiment of the present invention, after the terminal performs a proportional operation on the first real-time throughput and the second real-time throughput to obtain a ratio result of the first real-time throughput and the second real-time throughput, if the ratio result is smaller than a preset ratio threshold, the terminal may determine that the preset wireless network handover condition is satisfied.

Further, in the embodiment of the present invention, the terminal may preset a preset ratio threshold, where the preset ratio threshold is used to determine whether to perform wireless network handover. Specifically, the terminal may set the preset ratio threshold to 0.7, and when the ratio calculated by the terminal is less than 0.7, the terminal may determine that the preset wireless network handover condition is satisfied.

And 103c, when the ratio result is greater than or equal to the preset ratio threshold, judging that the preset wireless network switching condition is not met.

In an embodiment of the present invention, after the terminal performs a proportional operation on the first real-time throughput and the second real-time throughput to obtain a ratio result of the first real-time throughput and the second real-time throughput, if the ratio result is greater than or equal to a preset ratio threshold, the terminal may determine that the preset wireless network switching condition is not satisfied.

Further, in an embodiment of the present invention, after detecting the real-time throughputs of the first wireless network and the second wireless network and obtaining the first real-time throughput and the second real-time throughput, the terminal may calculate a ratio result of the first real-time throughput and the second real-time throughput, and then further determine whether to switch to the second wireless network according to the ratio result and the preset ratio threshold, instead of directly switching to access the second wireless network after determining that the first throughput is smaller than the second throughput, so that a defect of power consumption increase caused by frequently switching to access the wireless network may be overcome.

As can be seen from the above description, in the steps 103a to 103c, the terminal performs proportional operation on the first real-time throughput and the second real-time throughput to obtain a ratio result of the first real-time throughput and the second real-time throughput; when the ratio result is smaller than a preset ratio threshold value, judging that a preset wireless network switching condition is met; when the ratio result is greater than or equal to a preset ratio threshold value, judging that the preset wireless network switching condition is not met; in a terminal configured with two radio frequency modules, the throughput of two connected wireless networks can be detected in real time, and the wireless networks are switched according to the throughput, so that the defect that the service using the wireless networks in the terminal is interrupted can be effectively overcome in the process of switching the wireless networks, and the normal work of the terminal is ensured; moreover, the method is simple and convenient to realize, convenient to popularize and wide in application range.

step 1010, disconnecting the first radio frequency module from the first wireless network.

In an embodiment of the present invention, after the terminal performs the wireless handover processing and accesses to the second wireless network through the second rf module, the terminal may disconnect the connection between the first rf module and the first wireless network.

It should be noted that, in the embodiment of the present invention, after the terminal switches to the second wireless network, the connection between the first radio frequency module and the first wireless network may be disconnected, so as to select a backup wireless network with a stronger actual data transmission capability for connection.

step 1011, reacquire a plurality of alternate wireless networks.

In an embodiment of the present invention, after the terminal disconnects the first radio frequency module from the first wireless network, the terminal may reacquire a plurality of standby wireless networks.

It should be noted that, in the embodiment of the present invention, the terminal may continue to acquire, in the specific location having the plurality of fixed wireless networks, the plurality of standby wireless networks in the location.

Specifically, in the embodiment of the present invention, the plurality of standby wireless networks that the terminal is reacquiring may be a plurality of standby wireless networks that do not include the second wireless network. For example, after the terminal acquires 4 fixed wireless networks, namely, a mall wireless network 1, a mall wireless network 2, a mall wireless network 3 and a mall wireless network 4 in the mall, the first radio frequency module is connected to the mall wireless network 3, and is connected to the mall wireless network 2 through the second radio frequency module, when the terminal is switched to be connected to the mall wireless network 2 from the mall wireless network 3, the spare wireless network acquired again by the terminal does not include the mall wireless network 2.

In an embodiment of the present invention, after the terminal reacquires the plurality of standby wireless networks, the terminal may detect a plurality of throughputs corresponding to the plurality of standby wireless networks. Specifically, one standby wireless network corresponds to one throughput.

It should be noted that, in the embodiment of the present invention, after the terminal acquires the plurality of standby wireless networks, it is necessary to detect the throughput of each wireless network first to determine the actual data transmission capability of each wireless network, so as to further select a standby wireless network that can be connected to the first social evaluation module from the plurality of standby wireless networks.

Step 1013 is to update the first wireless network according to the standby wireless network corresponding to the maximum throughput among the plurality of throughputs.

In an embodiment of the present invention, after detecting a plurality of throughputs corresponding to a plurality of standby wireless networks, the terminal may update the first wireless network according to a standby wireless network corresponding to a maximum throughput among the plurality of throughputs.

Further, in an embodiment of the present invention, the terminal may determine, from the plurality of standby wireless networks, one standby wireless network with the highest throughput, and determine the standby wireless network with the highest throughput as a new first wireless network. For example, after the terminal is disconnected from the first wireless network, which is the mall wireless network 3, the throughput 1 of the mall wireless network 1, the throughput 3 of the mall wireless network 3, and the throughput 4 of the mall wireless network 4 are obtained, and the throughputs are throughput 1, throughput 3, and throughput 4 in the descending order, so that the terminal can update the mall wireless network 3 to the mall wireless network 1.

Step 1014, connect the first radio frequency module to the first wireless network.

In an embodiment of the present invention, after the terminal updates the first wireless network according to the standby wireless network corresponding to the maximum throughput of the plurality of throughputs, the terminal may connect the first radio frequency module to the first wireless network.

It should be noted that, in the embodiment of the present invention, after the terminal completes the wireless network handover, that is, after the terminal switches from accessing the first wireless network through the first radio frequency module to accessing the second wireless network through the second radio frequency module, the throughput of the multiple standby wireless networks may be detected again, so as to select one standby wireless network with the largest throughput and reconnect to the first radio frequency module.

Further, after the terminal connects the first radio frequency module to the updated first wireless network, the terminal may continue to detect the throughput of the first wireless network and the throughput of the second wireless network according to the first preset time interval, so as to perform wireless network handover on the terminal when the preset wireless network handover condition is met.
