All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The Mobile terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like, which have wireless communication functions. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal. The following describes embodiments of the present invention in detail.

Referring to fig. 1, fig. 1 is a schematic flow chart of a network access handover method according to an embodiment of the present invention, where as shown in the figure, the network access handover method includes:

s101, a mobile terminal detects whether the mobile terminal meets a network access switching condition;

the network access switching condition may be a distance condition from a hotspot of the wlan, or a signal strength condition of the wlan or a mobile communication network, which is not limited herein, but the network access switching condition is a strict condition for enabling the mobile terminal to have stable data connection, where the strict condition for enabling the mobile terminal to have stable data connection is not only a condition for enabling the mobile terminal to access when scanning for the wlan, or a condition for disabling the mobile terminal when scanning for the wlan, and the wlan may access when providing stable data traffic for the mobile terminal, or a condition for disabling the mobile terminal when detecting that there is no stable data traffic when accessing the wlan.

The network access switching refers to access switching of network resources accessed by a mobile terminal, that is, whether the mobile terminal is accessed to a wireless local area network, a mobile communication network, or a mobile communication hotspot.

S102, when the mobile terminal detects that the mobile terminal meets the network access switching condition, switching the network access of the mobile terminal, and forbidding a network access switching function in a preset time period;

the switching of the network access of the mobile terminal may be switching of the mobile terminal from a mobile communication network to a wireless local area network, or switching of the mobile terminal from the wireless local area network to the mobile communication network.

The forbidding of the network access switching function in the preset time period is to forbid all operations related to the network access switching in the preset time period, and in order to ensure the stability of the network, it is not necessary to detect whether the mobile terminal meets the network access switching condition, and it is not necessary to perform scanning operation for the wireless local area network, and it is not necessary to perform network access switching.

And after the preset time period, the mobile terminal recovers and starts the network access switching function.

In one possible example, before the detecting whether the mobile terminal satisfies the network access handover condition, the method further includes:

when detecting that a first wireless local area network is accessed, detecting first signal strength of the first wireless local area network;

when the first signal intensity is detected to be smaller than a first preset threshold value, acquiring a first position;

when the interruption of the access to the first wireless local area network is detected, acquiring a second position;

and determining a first reference area of the first wireless local area network by taking the first position as a circle center and the distance between the first position and the second position as a radius, wherein the first reference area is an effective coverage area of the first wireless local area network relative to the mobile terminal.

Wherein the first preset threshold is dynamic, that is, the first preset threshold changes during the process that the mobile terminal continuously accesses the first wireless local area network, and a trend of the change of the first preset threshold becomes smaller and smaller, for example, the first preset threshold may be-30 dbm, -35dbm, -40 dbm.

For example, when it is determined that the current signal strength of the first wireless local area network is-35 dbm smaller than the first preset threshold value of-30 dbm, determining that the position with the signal strength of-35 dbm is a first position, and updating the first preset threshold value of-35 dbm, in the process that the mobile terminal continuously accesses the first wireless local area network, if it is detected that the position with the signal strength of-40 dbm is smaller than the updated first preset threshold value, updating the first position as the position with the signal strength of-40 dbm, and updating the first preset threshold value of-40 dbm.

The first position is a central position of the first reference area of the first wireless local area network, that is, a position in the first reference area where the signal strength relative to the mobile terminal is strongest is a determined hotspot position of the first wireless local area network.

Wherein the first position and the second position are both position parameters, and the position parameters include three-dimensional coordinate parameters of the positions.

As can be seen, in this example, the mobile terminal determines the first reference area of the first wireless local area network relative to the mobile terminal according to the situation that the mobile terminal accesses the first wireless local area network and interrupts accessing the first wireless local area network, instead of enabling all the mobile terminals to have the same first reference area for the first wireless local area network, which is beneficial to improving the accuracy of the mobile terminal in acquiring the first reference area, and sets the dynamic first preset threshold, which is beneficial to further improving the accuracy of the first reference area.

In this possible example, the switching the network access of the mobile terminal when detecting that the mobile terminal satisfies the network access switching condition includes:

when the mobile terminal is detected to be transferred from a second reference area of the first wireless local area network to the first reference area, and a first distance between the mobile terminal and a signal source of the first wireless local area network is smaller than a second distance, switching network access of the mobile terminal to the first wireless local area network, wherein the second reference area is an area except the first reference area, and the second distance is a radius of the first reference area.

The first distance is a distance which can ensure that the data connection is stable after the mobile terminal is accessed into the first wireless local area network.

When the mobile terminal is transferred from a second reference area of the first wireless local area network to the first reference area, although the first reference area is an effective coverage area of the first wireless local area network, the mobile terminal does not perform an access control operation for the first wireless local area network, but performs an access control operation for the first wireless local area network when a signal source of the first wireless local area network is a first distance, and the first distance is smaller than the second distance.

And the signal source of the first wireless local area network is the determined circle center position of the first reference area.

When the mobile terminal is transferred from the second reference area of the first wireless local area network to the first reference area, the moving direction of the mobile terminal is the moving direction of the mobile terminal, that is, the mobile terminal is closer to the signal source of the first wireless local area network.

The mobile terminal may perform a network access handover operation at a first location among the plurality of locations, where the first location is a first distance from a signal source of the first wireless local area network in the first reference area.

When the mobile terminal is detected to be transferred from the second reference area of the first wireless local area network to the first reference area, the mobile terminal can predict a motion track according to motion acceleration and a motion direction, predict a position which is a first distance away from a signal source of the first wireless local area network in a position set forming the motion track according to the motion track, then predict a time node reaching the position, and perform network access switching operation when the predicted time node is reached.

The mobile terminal comprises an accelerometer and a gyroscope for acquiring motion acceleration and motion direction.

As can be seen, in this example, the mobile terminal does not immediately perform the access control operation for the first wireless local area network when reaching the first reference area, but performs the access control when the signal source of the first wireless local area network is a first distance, so as to avoid a situation that data connection is interrupted due to weak signal strength of the wireless local area network after the mobile terminal accesses the first wireless local area network quickly, which is beneficial to improving the stability of wireless data traffic of the mobile terminal.

and when the mobile terminal is detected to move from the first reference area of the first wireless local area network to the second reference area and the third distance between the mobile terminal and the signal source of the first wireless local area network is smaller than the second distance, switching the network access of the mobile terminal into a mobile communication network.

The moving direction of the mobile terminal is from the first reference area to the second reference area, that is, the mobile terminal is farther from a signal source of the first wireless local area network.

And the third distance is a critical value of the mobile terminal in which the data connection in the first reference area is unstable.

The mobile terminal can predict the position of the mobile terminal, which is a third distance from a signal source of the first wireless local area network, in a position set forming the motion trail to the second reference area from the first reference area of the first wireless local area network according to the motion trail, then predict a time node reaching the position, and perform network access switching operation when the predicted time node is reached.

As can be seen, in this example, when the mobile terminal detects that the first reference area of the first wireless lan moves to the second reference area and the third distance from the signal source of the first wireless lan is smaller than the second distance, the mobile terminal switches the network access to the mobile communication network instead of performing the network access switching operation after the mobile terminal reaches the boundary of the first reference area, so as to avoid a situation that data connection is interrupted at the boundary of the first reference area due to weak signal strength of the first wireless lan and no active disconnection of the first wireless lan, which is beneficial to further improving the stability of data connection of the mobile terminal.

In one possible example, the switching the network access of the mobile terminal when detecting that the mobile terminal satisfies the network access switching condition includes:

when detecting that a plurality of groups of second signal strengths of a second wireless local area network acquired by the mobile terminal are in a decreasing trend and the plurality of groups of second signal strengths comprise at least one second signal strength of which the signal strength is smaller than a second preset threshold value, switching the network access of the mobile terminal to the second wireless local area network;

or,

and when detecting that the multiple groups of third signal strengths of the second wireless local area network acquired by the mobile terminal are in an increasing trend and the multiple groups of third signal strengths comprise at least one third signal strength of which the signal strength is greater than a third preset threshold value, switching the network access of the mobile terminal into a mobile communication network.

The second signal strength is smaller and smaller, which indicates that the second signal strength is stronger and stronger, and the second signal strength is larger and larger, which indicates that the second signal strength is weaker and weaker.

The mobile terminal moves from the edge of the second wireless local area network to the center of the second wireless local area network when the plurality of sets of second signal strengths of the second wireless local area network trend to be decreased, and the mobile terminal moves from the center of the second wireless local area network to the edge of the second wireless local area network when the plurality of sets of third signal strengths of the second wireless local area network trend to be increased.

It can be seen that, in this example, the mobile terminal detects a variation trend of the signal strength of the second wireless local area network, and determines the time for switching the network access according to the variation trend and the value of the signal strength, so as to avoid a situation that data connection is interrupted due to weak signal strength after the second wireless local area network is connected without considering a moving direction of the mobile terminal, and further improve stability of data connection of the mobile terminal.

detecting a fourth signal strength of a third wireless local area network when detecting that the third wireless local area network is accessed;

when the fourth signal intensity is detected to be smaller than a fourth preset threshold value, acquiring a third position;

when detecting that the fourth signal intensity is greater than a fifth preset threshold value, acquiring a fourth position;

and determining a third reference area of the third wireless local area network by taking the third position as a center of a circle and the distance between the third position and the fourth position as a radius, wherein the third reference area is an effective coverage area of the third wireless local area network relative to the mobile terminal.

The fourth preset threshold is dynamic, that is, the fourth preset threshold changes in the process that the mobile terminal continuously accesses the third wireless local area network, and the change trend of the fourth preset threshold is smaller and smaller, which is the same as the first preset threshold.

The third position is a central position of the third reference area of the third wireless local area network, that is, a position in the third reference area where the signal strength relative to the mobile terminal is strongest is a determined hotspot position of the third wireless local area network.

And the third position and the fourth position are both position parameters, and the position parameters comprise three-dimensional coordinate parameters of the positions.

In this example, the mobile terminal determines, according to the signal strength of the third wireless local area network when the mobile terminal accesses the third wireless local area network, a smaller effective coverage area of the third wireless local area network relative to the mobile terminal itself, and determines the radius of the third reference area when the signal strength is greater than a fifth preset threshold, instead of determining the radius of the third reference area when the signal strength is not detected, which is beneficial to enabling the mobile terminal to obtain a fourth reference area with stable data connection, so that the mobile terminal can perform network access switching more accurately according to the reference area.

when detecting that the mobile terminal is transferred from a fourth reference area of the third wireless local area network to the third reference area, switching the network access of the mobile terminal to the third wireless local area network, wherein the fourth reference area is an area except the third reference area;

or,

and when the mobile terminal is detected to be transferred from the third reference area of the third wireless local area network to the fourth reference area, switching the network access of the mobile terminal to a mobile communication network.

The mobile terminal can predict the time node of the mobile terminal transferred from the fourth reference area to the third reference area according to the motion trail, or predict the time node of the mobile terminal transferred from the third reference area to the fourth reference area according to the motion trail, when the predicted time node is reached, network access switching operation is carried out, the mobile terminal predicts the time node through the motion trail instead of determining through positioning, and therefore the mobile terminal is beneficial to improving the real-time performance of network access switching of the mobile terminal and reducing power consumption during positioning.

Therefore, in this example, the mobile terminal performs network access switching according to the effective coverage area of the third wireless local area network determined by the mobile terminal to have stable data connection, so that the situation that the signal of the third wireless local area network is weak at the edge of the effective area when the effective coverage area is large, and the data connection is interrupted although the third wireless local area network is connected is avoided, and the stability of the data connection of the mobile terminal is further improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of another network access handover method according to an embodiment of the present invention, where the network access handover method includes:

wherein the second reference region is a region other than the first reference region, and the second distance is a radius of the first reference region.

S207, after the preset time period, when the mobile terminal detects that the mobile terminal moves from the first reference area to the second reference area of the first wireless lan, and a third distance between the mobile terminal and a signal source of the first wireless lan is smaller than the second distance, switching the network access of the mobile terminal to a mobile communication network, and disabling a network access switching function in the preset time period.

In addition, the mobile terminal determines the first reference area of the first wireless local area network relative to the mobile terminal according to the condition that the mobile terminal accesses the first wireless local area network and interrupts the first wireless local area network, and therefore the accuracy of the mobile terminal in acquiring the first reference area is improved.

In addition, the mobile terminal does not immediately perform access control operation aiming at the first wireless local area network when reaching the first reference area, but performs access control when the signal source of the first wireless local area network is a first distance, thereby avoiding the situation that the data connection is interrupted due to the weak signal strength of the wireless local area network after the mobile terminal is accessed into the first wireless local area network quickly, and when the mobile terminal detects that the mobile terminal moves from the first reference area of the first wireless local area network to the second reference area and the third distance from the signal source of the first wireless local area network is less than the second distance, the mobile terminal switches the network access to the mobile communication network instead of performing network access switching operation after the mobile terminal reaches the boundary of the first reference area, thereby avoiding the situation that the signal strength of the first wireless local area network is weak at the boundary position of the first reference area, and the data connection interruption caused by actively disconnecting the first wireless local area network is avoided, so that the stability of the data connection of the mobile terminal is further improved.

and S303, after the preset time period, when the mobile terminal detects that multiple groups of third signal strengths of the second wireless local area network acquired by the mobile terminal are in an increasing trend and the multiple groups of third signal strengths comprise at least one third signal strength of which the signal strength is greater than a third preset threshold, switching the network access of the mobile terminal to a mobile communication network, and forbidding a network access switching function in the preset time period.

In addition, the mobile terminal detects the change trend of the signal intensity of the second wireless local area network, and determines the time for switching the network access according to the change trend and the value of the signal intensity, so that the situation that the data connection is interrupted due to weak signal intensity after the second wireless local area network is connected under the condition that the moving direction of the mobile terminal is not considered is avoided, and the stability of the data connection of the mobile terminal is further improved.

In case of an integrated unit, fig. 5 shows a possible structural diagram of the mobile terminal involved in the above embodiment. The mobile terminal 500 includes: a processing unit 502 and a communication unit 503. Processing unit 502 is used to control and manage the actions of the mobile terminal, e.g., processing unit 502 is used to support the mobile terminal to perform steps S101 to S102 in fig. 1, steps S201 to 207 in fig. 2, steps S301 to S303 in fig. 3, and steps S401 to S407 in fig. 4, and/or other processes for the techniques described herein.
