Detailed Description
In order to make the objects, 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 drawings in the embodiments of the present invention, 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.
Fig. 1 is a flowchart of a first embodiment of a network handover method according to the present invention, and as shown in the figure, the network handover method includes the following steps:
s101, detecting the network signal intensity of a certain SSID (Service Set Identifier) which is accessed currently.
When a terminal device, such as a mobile phone, a notebook computer, a tablet computer, etc., accesses the internet through a wireless network in an area where the terminal device is connected, the signal strength of the wireless network to which the terminal device is connected may change due to various reasons, such as a change in the distance between the terminal device and a signal source, a change in the number of devices using the same wireless network at the same time, etc., and at this time, the terminal device is required to detect the network signal strength corresponding to the SSID to which the terminal device has accessed to see whether the requirement of the terminal device for the internet access rate is met.
And S102, if the network signal intensity is lower than a preset switching threshold value, sequencing the network signal intensities corresponding to other SSIDs which are authorized to be used, and acquiring a sequencing result.
Generally speaking, the wireless network signal strength connected with the terminal equipment consists of four arcs from short to long, and the weaker the wireless signal is, the fewer the number of the black arcs is. In the terminal device, the user may set a switching threshold, such as-80 dBm, for the signal strength of the connected wireless network in advance according to the requirement of the terminal device for the internet access speed, and two black signal lines are displayed on the terminal device corresponding to the switching threshold. When the signal intensity of the SSID connected with the terminal equipment is lower than the preset switching threshold value and only one black signal line is displayed in the signal intensity of the terminal equipment, the terminal equipment sorts the network signal intensities corresponding to other SSIDs which the terminal equipment has the authority to use, and a sorting result is obtained.
S103, according to the sequencing result, switching the network corresponding to the currently accessed SSID to the network corresponding to other SSIDs in the sequencing result.
After the terminal device obtains the sorting results of the signal strengths of all SSIDs authorized to use, the network corresponding to the currently connected SSID is switched to one of the networks corresponding to all SSIDs authorized to use and sorted by the terminal device.
In this embodiment, the terminal device detects the strength of a network signal corresponding to a currently accessed SSID; if the network signal intensity is lower than the preset switching threshold value, the terminal equipment sorts the network signal intensities corresponding to other SSIDs which are authorized to be used, and a sorting result is obtained; and the terminal equipment switches the network corresponding to the currently accessed SSID to the network corresponding to the other SSID in the sequencing result according to the sequencing result. The intelligent SSID switching method can avoid the problems that the SSID signal connected with the terminal equipment is weakened and even the network connection is interrupted along with the increase of the distance from the connected SSID source in the moving process of the terminal equipment, and the terminal equipment automatically carries out the SSID connection mode with strong signal, thereby bringing better network experience to users.
Optionally, before executing S101, the terminal device may further search all SSIDs in the area where the terminal device is located, apply for the authority for each SSID, and store all SSIDs applied for the authority, thereby facilitating subsequent network switching selection.
Optionally, the terminal device may directly perform network handover without being perceived by the user, or may first inquire whether the user needs to perform network handover before performing handover, and determine whether to perform network handover and to which network to perform specific handover according to a response of the user.
For the technical scheme that the terminal device automatically switches the network without user perception, the following optional technical scheme may be included:
according to the sequencing result, switching the network corresponding to the currently accessed SSID to the network corresponding to the SSID with the highest network signal intensity in the sequencing result;
specifically, it may be the method shown in fig. 2, if the terminal device may have the right to use five different SSIDs, named SSID1, SSID2, SSID3, SSID4 and SSID5, respectively, and if the terminal device is connected to SSID1, the signal strength has been smaller than the connection threshold, and the signal strengths of the other four SSIDs are shown as: SSID2 is one black signal line, SSID3 is two black signal lines, SSID3 is three black signal lines, SSID5 is four black signal lines, and the terminal device arranges SSIDs 2-SSID5 in the following order: SSID5, SSID4, SSID3, SSID2, and then the terminal device will switch the connected SSID1 to SSID5 for the user to use to access the internet.
Determining at least two SSIDs of which the network signal intensity exceeds a preset intensity threshold value in the sequencing result, determining the SSID with the highest switching frequency in the at least two SSIDs, and switching the network corresponding to the currently accessed SSID to the network corresponding to the SSID with the highest switching frequency;
specifically, it may be the method shown in fig. 3, when there are four SSIDs authorized to be used in the area where the terminal device is located, which are named as SSID-a, SSID-b, SSID-c, and SSID-d, respectively, if the signal strength of the SSID-a connected to the terminal device is smaller than the connection threshold, the signal strengths of the other three SSIDs are greater than the threshold, and the signal strengths of the SSID-b and SSID-c are the same and stronger than the signal strength of the SSID-d, the background compares frequency data of the SSID-b and SSID-c used by the user at ordinary times, and if it is found that the frequency of the SSID-b used by the user is greater than the frequency of the SSID-c used by the user, the terminal device automatically switches the SSID-a connected to SSID-b for the user to access the internet.
And determining at least two SSIDs in the sequencing result, wherein the network signal strength exceeds a preset strength threshold, determining the SSID with the highest data transmission speed in the at least two SSIDs, and switching the network corresponding to the currently accessed SSID to the network corresponding to the SSID with the highest data transmission speed.
Specifically, it may be the method shown in fig. 4, when there are four SSIDs authorized to be used in the area where the terminal device is located, which are named as SSID-A, SSID-B, SSID-C and SSID-D, respectively, if the signal strength of the SSID-a connected to the terminal device is smaller than the connection threshold, the signal strengths of the other three SSIDs are greater than the threshold, and the signal strengths of the SSID-B and SSID-C are the same and stronger than the signal strength of SSID-D, the background compares the data transmission speeds of SSID-B and SSID-C, and if the data transmission speed of SSID-B is greater than the data transmission speed of SSID-C, the terminal device switches the connected SSID-a to SSID-B.
The switching policies in the various network switching processes may be preset by the device manufacturer when the terminal device leaves the factory, or preset in the terminal device by the user.
For the network switching perceived by the user, before S103, the terminal device may send a network switching request message to the user, so as to prompt the user that the network switching needs to be performed and ask the user whether the network switching needs to be performed, and after receiving a network switching confirmation message sent by the user, the terminal device switches the network corresponding to the currently accessed SSID to the network corresponding to the other SSID in the ranking result according to the ranking result.
In particular implementation, the user may also participate in network selection to indicate the network to be selected by the terminal device. The following two schemes can be adopted for implementation:
the first scheme is as follows: the terminal device loads the sequencing result in the network switching request message and sends the network switching request message to the user, and after the user selects the SSID required to be switched according to the sequencing result, the user can load the selected SSID in the network switching confirmation message and then send the network switching confirmation message to the terminal device.
For example, as shown in fig. 5, the terminal device may present all SSID names and signal strengths authorized to be used in a popup format on a display interface of the terminal device, where the SSID names may be sorted from weak to strong according to the signal strengths. In this embodiment, the SSID connected to the terminal device is "number 1", the user may select the SSID required to be switched from the switchable SSIDs, and after the user clicks the "confirm" item in the window, the terminal device may send a network switching confirmation message with the SSID required to be switched by the user to the terminal device, for example, the user selects "number 5" SSID, and the terminal device may know the SSID that the user wants to switch from the message, so as to switch the "number 1" network to the "number 5" network for the user to access the internet.
The user may make the selection based on various considerations, such as the maximum signal strength of the network, the frequently selected network, and so on.
Scheme II: the terminal device can acquire the network signal strength of all the SSIDs which the user has authority to connect with, so as to obtain a sequencing result, the terminal device can not completely send the sequencing result to the user for the user to select the SSID, but can pre-select at least two SSIDs of which the network signal strength exceeds a preset strength threshold value from all the SSIDs, bear the at least two SSIDs in a network switching request message and send the SSIDs to the user for the user to select, and the user can select one SSID from the at least two SSIDs and bear the SSID in a network switching confirmation message to send the terminal device.
For example, as shown in fig. 6, the terminal device pops up a handover request window to the user, where the window includes two SSIDs with the same signal strength and network signal strength pre-selected by the terminal device from all SSIDs, and the SSID to which the terminal device is connected, where the two pre-selected SSIDs may be the two with the best signal strength in the area where the terminal device is located. In this embodiment, the SSID connected to the terminal device is No.1, and the alternative SSIDs are No.2 and No.3, respectively, so that the user can select the SSID to be switched from the switchable SSIDs, and after the user clicks the "confirm" item in the window, the terminal device can send a network switching confirmation message with the SSID to be switched to the user to the terminal device, for example, the user selects the "No. 2" SSID, and the terminal device can know the SSID that the user wants to switch from the message, so as to switch the connected "No. 1" network to the "No. 2" network for the user to access the internet.
The user can choose according to various considerations, such as frequently selected networks, etc
In this embodiment, switching a network corresponding to an SSID to which the terminal device has accessed to a network corresponding to another SSID in the sequencing result includes two ways: the method comprises the steps of user-unaware network switching and user-aware network switching, wherein the user-unaware network switching mode is that the terminal equipment automatically switches the SSID in the background, the user-aware network switching mode is that the terminal equipment presents the SSID sequencing result which is authorized to be used to the user, and the user determines whether the wireless network needs to be switched. The two ways of switching the SSID by the terminal equipment can bring better network experience to users.
