In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.
In view of the problem of poor reliability of the existing network connection method, the invention provides a network connection method, a network connection device and a mobile terminal to improve the problem, which can effectively improve the reliability of network connection and further improve the user experience.
To facilitate understanding of the present embodiment, first, a detailed description is given to a network connection method disclosed in the embodiment of the present invention, which is applied to a mobile terminal, such as a device applied to a smart phone or a tablet computer, with reference to a flowchart of a network connection method shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102, if the mobile terminal is monitored to be switched from the current network to the target network, whether the network speed of the target network connected through the current address is smaller than a preset threshold value is judged.
In practical application, the mobile terminal registers the current network to obtain an Internet Protocol (IP) Address corresponding to the current network, and connects to the current network through the IP corresponding to the current network, wherein the IP corresponding to the current network is also the current Address, and if the mobile terminal is switched from the current network to the target network, the current network is connected to the target network through the current Address. For example, if the mobile terminal is switched from the 3G network to the 4G network, the mobile terminal first connects to the 4G network using the IP corresponding to the 3G network, and detects the network connection speed for comparing with the preset threshold.
And step S104, if yes, acquiring the target address.
In one embodiment, the target address obtained by registration is stored in a designated area, and when the network speed of connecting with the target network through the current address is determined to be less than a preset threshold value, that is, when the network speed of connecting with the target network through the current address is determined to be less or the network connection fails, the mobile terminal can directly read the target address from the designated area, wherein the target address can be understood as an IP corresponding to the target network.
And step S106, connecting the target network through the target address.
When the network speed of connecting the target network through the current address is less than the preset threshold, it indicates that the mobile terminal cannot keep a better connection state with the target network through the current address, and in order to alleviate the problem that the user cannot surf the internet due to a poor network connection state, the embodiment of the invention adopts the target address to establish the connection between the mobile terminal and the target network.
In the network connection method provided by the embodiment of the invention, when it is monitored that the mobile terminal is switched from the current network to the target network and the network speed for connecting the target network through the current address is less than the preset threshold value, the target address obtained by registering the target network is obtained and the target network is connected through the target address. According to the method, when the network speed of the current address connected with the target network is smaller than the preset threshold value, the current address is switched to the target address, and compared with the mode that the current address is connected with the target network in the prior art, the target address obtained by registering the target network can be timely connected with the target network, so that the reliability of network connection is better improved, and the network connection experience of a user is improved.
Generally, in a data network, the network speed of a 5G network is the fastest, the network speed of a 4G network is the second, the network speed of a 3G network is the slower, and the network speed of a 2G network is the slowest, and in order to enable a user to experience a faster network connection speed, the priority of each data network is usually set according to the network connection speed, so that the mobile terminal of the user is switched to the data network with a higher priority when meeting the access condition of the data network with the higher priority.
In one embodiment, if the priority of the current network is lower than that of the target network, the embodiment of the present invention may perform handover from the current network to the target network according to the following steps (1) to (2): (1) and searching a target network according to a preset protocol standard, and judging whether the searched target network meets a preset access condition. The protocol specification may include a period for searching for a target network, so that the mobile terminal may search for the target network according to the period, and if the mobile terminal searches for a target network having a higher priority than a current network, determine whether the searched target network satisfies a preset access condition, where the preset access condition may include a frequency range or a signal strength, and the like, such as when the frequency range of the target network is within a preset range and the signal strength of the target network is greater than a preset strength threshold, it is determined that the target network satisfies the preset access condition. (2) If so, registering the target network, and connecting the target network through the current address to switch from the current network to the target network. When the searched target network meets the preset access condition, the mobile terminal registers the target network to obtain a target address corresponding to the target network, and sends a connection request to the target network through the AP side based on the current address, so that the target network is connected through the current address. For example, the current network of the mobile terminal is a 3G network, if the mobile terminal searches for a 4G network once every minute, if the searched 4G network meets the preset 4G access condition, the mobile terminal registers the 4G network to obtain a target address corresponding to the 4G network, and at this time, the mobile terminal connects to the 4G network through the current address corresponding to the 3G network, so as to implement a switching process from the 3G network to the 4G network.
In another embodiment, if the priority of the current network is higher than that of the target network, the mobile terminal switches from the current network to the target network when the preset access condition of the current network is not met, for example, the current network of the mobile terminal is a 4G network, when the mobile terminal cannot be connected to the 4G network due to the fact that the 4G network is not deployed in the area where the mobile terminal is located or due to other reasons, the mobile terminal determines whether the 3G network meets the preset 3G access condition, and connects to the 3G network through the current address corresponding to the 4G network when the 3G network meets the preset access condition, so as to implement a switching process from the 4G network to the 3G network. The 3G access condition may be different from the 4G access condition.
Considering that when the network connection speed of the mobile terminal is low, the waiting time of the user for accessing the page is prolonged, and further the user experience is poor, so that in order to reduce the waiting time of the user for accessing the page, the embodiment of the present invention determines whether the network speed of the mobile terminal for connecting with the target network through the current address is less than the preset threshold, and obtains the target address obtained by registering the target network when the determination result is yes, and further connects with the target network through the target address, wherein when determining whether the network speed of the mobile terminal for connecting with the target network through the current address is less than the preset threshold, the embodiment of the present invention can refer to the following steps a to c:
and a, generating first communication data on the basis of the current address through the AP side of the mobile terminal. In one embodiment, the mobile terminal reports the current address to the AP side, generates a connection request including the current address through the AP side, and uses the connection request including the current address as the first communication data.
And b, judging whether the target network responds to the first communication data within a preset time length. Generally, after the mobile terminal is switched from the current network to the target network, it needs to wait for several seconds (for example, 3 seconds) before the mobile terminal can successfully connect with the target network, so in order to reduce the possibility of misjudgment on the network connection state during the waiting period, in the embodiment of the present invention, whether the target network responds to the first communication data is determined within a preset time period after the mobile terminal is switched from the current network to the target network. In a specific embodiment, the timing duration of the timer T may be preset to 10 seconds, when the mobile terminal switches from the current network to the target network, the mobile terminal starts the timer T, and within 10 seconds, the mobile terminal sends the first communication data to the target network through the AP side, and detects whether the target network responds to the uplink first communication data through the AP side, where the first communication data may be TCP (Transmission Control Protocol) data.
And c, if not, determining that the network speed of the target network connected through the current address is less than a preset threshold value. When the target network responds to the first communication data within the preset time, it can be determined that the mobile terminal fails to connect the target network through the current address, that is, the network speed of the mobile terminal connecting the target network through the current address is 0, and the preset threshold value can be any constant greater than 0, so that it can be determined that the network speed of connecting the target network through the current address is less than the preset threshold value.
To facilitate understanding of step S106, the embodiment of the present invention provides a specific implementation manner of connecting to the target network through the target address, as shown in step 1 to step 5:
step 1, reporting the target address to the AP side of the mobile terminal. For example, the mobile terminal is switched from the 3G network to the 4G network, a target address corresponding to the 4G network is obtained when the mobile terminal registers the 4G network, and if it is determined that the network speed for connecting with the target network through the current address is less than a preset threshold, the target address corresponding to the 4G network is reported to the AP side, so that the AP side connects with the target network through the target address.
And 2, generating second communication data on the basis of the target address through the AP side of the mobile terminal. The second communication data is also a connection request including a destination address, and is also TCP data. For example, when the AP side receives the reported destination address corresponding to the 4G network, the AP side generates second communication data including the destination address corresponding to the 4G network, so as to request to connect to the destination network through the destination address corresponding to the 4G network.
And 3, judging whether the target network responds to the second communication data within the preset time length. If yes, executing step 4; if not, go to step 5. For example, the mobile terminal sends second communication data containing a target address corresponding to the 4G network to the target network through the AP side, and detects whether the target network responds to the second uplink communication data within a preset time duration through the AP side, and if so, may determine that the network speed for connecting to the target network through the target address is not less than a preset threshold, and may further connect to the target network through the target address.
And 4, connecting the target network through the target address. Wherein the process that the target network responds to the second communication data indicates that the mobile terminal has successfully connected to the target network through the target address. For example, the 4G network responds to the second communication data including the destination address corresponding to the 4G network, which indicates that the mobile terminal has established a connection with the 4G network through the destination address corresponding to the 4G network.
And 5, re-registering the target network to obtain a new target address, and connecting the target network through the new target address. When the AP side detects that the target network does not respond to the second uplink communication data within the preset time period, it indicates that the mobile terminal cannot maintain a better connection state with the target network through the target address, so that the mobile terminal provided in the embodiment of the present invention may perform attach again to re-register the target network to obtain a new target address, report the new target address to the AP side of the mobile terminal, the AP side generates a connection request including the new target address, and sends the connection request to the target network, if the AP side detects that the target network responds to the connection request, the mobile terminal may connect to the target network through the new target address, and if the AP side detects that the target network does not respond to the connection request, the mobile terminal repeatedly performs step 5 to perform attach again until the target network responds to the new target address, and connects to the target network through the new target address. It should be noted that the new destination address obtained by the mobile terminal every time the attach is performed may be different.
On the basis of the network connection method provided in the foregoing embodiment, an embodiment of the present invention provides a specific application example of a network connection method, where the method is applied to a mobile phone, a current network includes an evdo (Evolution Data only) network, a target network includes an LTE (Long Term Evolution) network, and referring to a flow diagram of another network connection method shown in fig. 2, the method mainly includes the following steps S202 to S214:
step S202, the mobile phone registers the EVDO network (i.e., the current network) to obtain the IP address a (i.e., the current address). The EVDO is a 3G network, when the EVDO network cell is searched by the mobile phone and the preset access condition is met, the EVDO network is registered to obtain an IP address A, and the EVDO network is connected through the IP address A.
Step S204, the mobile phone switches to the LTE network (i.e., the target network) to obtain the IP address B (i.e., the target address). The priority of the LTE network is higher than that of the EVDO network, so that when the mobile phone is connected with the EVDO network, an LTE network cell is searched according to a preset protocol specification, and when the searched LTE network cell meets a preset access condition, the LTE network is registered to obtain an IP address B, and a connection request containing the IP address A is sent to the LTE network through an AP side of the mobile phone so as to try to connect the LTE network through the IP address A.
Step S206, judging whether the mobile phone can be connected with the LTE network through the IP address A. If yes, go to step S214; if not, step S208 is performed. In practical application, whether the LTE network responds to a connection request containing an IP address A is detected through the AP side of the mobile phone, and if the LTE network does not respond to the connection request containing the IP address A, the mobile phone is determined to be incapable of connecting with the LTE network through the IP address A.
And step S208, the mobile phone is connected with the LTE network through the IP address B. When the mobile phone can not be connected with the LTE network through the IP address A, the mobile phone reports the IP address B to the AP side, and generates a connection request containing the IP address B through the AP side so as to request to connect with the LTE network.
And step S210, judging whether the mobile phone can be connected with the LTE network through the IP address B. If yes, go to step S214; if not, step S212 is performed. And the AP side detects whether the LTE network responds to the connection request containing the IP address B, and if the LTE network responds to the connection request containing the IP address B, the mobile phone is determined to be capable of connecting the LTE network through the IP address B.
Step S212, the mobile phone re-registers the LTE network to obtain an IP address C, and is connected with the LTE network through the IP address C. If the LTE network does not respond to the connection request containing the IP address B, the mobile phone re-registers the LTE network to obtain a new IP address C, and then reports the IP address C to the AP side, so that the AP side generates a connection request containing the IP address C to request to connect the LTE network. In practical application, if the IP address C still cannot be connected to the LTE network, the LTE network continues to be re-registered until an IP address that can be connected to the LTE network is obtained.
And step S214, the mobile phone is successfully connected with the LTE network.
In summary, in the network connection method provided in the embodiment of the present invention, after the mobile phone is switched from the EVDO network to the LTE network, it is determined whether the LTE network can be connected through the IP address a corresponding to the EVDO network, if the LTE network cannot be connected through the IP address a, the LTE network is connected through the IP address B corresponding to the LTE network, and if the LTE network cannot be connected through the IP address B, the IP address is obtained again until the mobile phone can establish connection with the LTE network. Compared with the prior art that the switched network is connected only through the IP address before switching, the method can better relieve the problem that the data network cannot be used due to network switching, and effectively improve the reliability of network connection.
