Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.
Example 1:
as shown in fig. 1, the present embodiment provides a method for switching a gateway, including:
s101, monitoring the current state of the portable gateway;
s102, determining an electric quantity threshold value according to the current state and the corresponding relation between the pre-stored state and the electric quantity threshold value;
s103, comparing the current electric quantity value with the determined electric quantity threshold value, and selecting to close the WiFi access mode when the current electric quantity value is lower than the determined electric quantity threshold value; selecting to remain on a WiFi access mode when the current power value is greater than or equal to the determined power threshold.
In the gateway switching method provided in this embodiment, different power thresholds may be determined according to different states of the portable gateway, and the WiFi access mode may be selected by comparing the current power of the portable gateway with the power threshold. If the current electric quantity is lower than the electric quantity threshold value, the WiFi access mode is selected to be closed, the WiFi access service is not provided for the terminal, so that the terminal is preferentially accessed to other gateways, and the electric quantity consumption of the portable gateways is reduced for the occasional need. According to the switching method of the gateway provided by the embodiment, the current state and the electric quantity of the portable gateway are considered in combination, the gateway can be intelligently switched according to different states of the portable gateway, the endurance time of the portable gateway is prolonged, and the frequency of switching the gateway by the terminal is reduced.
Example 2:
as shown in fig. 2, the present embodiment provides a method for switching a gateway.
The method is executed by the portable gateway and used for judging whether to provide WiFi access to the terminal and how to enable the terminal to select other gateways.
Specifically, the gateway switching method includes:
s201, preferably, the probability of the terminal accessing other gateways under different states is counted, the corresponding relation between the states and the electric quantity threshold value is determined according to the probability, and the determined corresponding relation is stored in the portable gateway.
And the higher the probability that the terminal accesses other gateways under the state corresponding to the electric quantity threshold value is, the higher the probability is.
Wherein, the state includes time, position and other information.
The time is the current time, and the position is the current position of the portable gateway, and can be obtained through a GPS positioning system and the like.
Specifically, the method comprises the following steps: firstly, the probability of accessing the terminal to other gateways in different states is obtained through statistics according to the history record of the previous operation of the terminal; then, determining the corresponding relation between different states and the electric quantity threshold value according to the probability; when the probability is lower, the corresponding power threshold is lower; and when the probability is higher, corresponding to a higher electric quantity threshold value, and storing the corresponding relation in the gateway along with the network.
Typically, there may be many other gateways around the terminal in addition to the wearable gateway to provide access to WiFi services. However, the probability that a terminal can access other gateways in different states is different, in other words, the number of available gateways around the terminal is different in different states, and even if there are a plurality of available gateways around the terminal (including the carry-on gateway and at least one other gateway), the terminal cannot necessarily access other gateways (gateways other than the carry-on gateway that the terminal can scan). According to the living and working habits of different users, the probability that the terminal used by the same user accesses other gateways under different states has a certain rule. For example, if a user is usually in the middle of the work at five pm, one hour is needed from company to home, and both the company and the home have wireless routers, the probability that the terminal used by the user accesses other gateways between five o 'clock and six o' clock is low, and the probability is high in other time periods. Therefore, the corresponding relation between different states and the electric quantity threshold value can be determined according to the probability that the terminal accesses other gateways in different states, so that the electric quantity threshold values of the portable gateways in different states are reasonably distributed, and the terminal can reasonably access the portable gateways.
Specifically, the step may be to count the number of times that the terminal attempts to access the other gateways and the number of times that the terminal successfully accesses the other gateways in different states within a certain time, so as to obtain the probability that the terminal accesses the other gateways in different states. For example, the probability that the terminal accesses other gateways in different states can be counted by letting the terminal try to access other gateways in different states and recording the number of success and failure in a period of time. Alternatively, the probability of accessing other gateways can be obtained according to the previous operation history of the portable gateway. For example, the gateway modes (the WiFi access mode is turned on or off) of the portable gateway in different states are recorded for multiple times, and the probability of accessing other gateways at terminals in different states is obtained according to the history.
And then, determining the corresponding relation between different states and the electric quantity threshold value according to the probability. When the probability is lower, the corresponding power threshold is lower; and when the probability is higher, corresponding to a higher electric quantity threshold value, and inputting the corresponding relation into the gateway per se.
The electric quantity threshold value is determined according to the probability of accessing the terminal to other gateways, and when the probability is lower, the electric quantity of the portable gateway is usually higher than the electric quantity threshold value by setting a lower electric quantity threshold value, so that the terminal is always accessed to the portable gateway as far as possible; when the probability is higher, the power of the carry-on gateway is easily lower than the power threshold value by setting a higher power threshold value, so that the terminal tries to access other gateways as much as possible in the state.
Therefore, the corresponding relation between different states and the electric quantity threshold is established according to the probability of accessing the terminal into other gateways, and the corresponding relation is stored in the portable gateway, so that the portable gateway selects the gateway mode according to the corresponding relation.
Of course, new data may be generated along with the use of the portable gateway or the terminal, and the new data may be added to the history record, and the probability that the terminal accesses other gateways in different states may be recalculated, so as to update the correspondence between the states and the power thresholds.
S202, monitoring the current state of the portable gateway.
And determining the current state of the carry-on gateway through monitoring.
The state of the terminal is usually the same as that of the portable gateway, and one portable gateway can be simultaneously accessed to a plurality of terminals, so that the state of the portable gateway or any terminal connected with the portable gateway is only required to be determined. However, the walkman gateway is fixed, and the terminal accessing the walkman gateway is any one or more terminals, and therefore, it is preferable to determine the state of the walkman gateway.
S203, determining the electric quantity threshold value according to the current state and the corresponding relation between the pre-stored state and the electric quantity threshold value.
Specifically, in this step, the current state of the wearable gateway determined in step S202 is matched with the state pre-stored in the wearable gateway in step S201, so as to determine the electric quantity threshold value to be set in the current state according to the corresponding relationship between the pre-stored state and the electric quantity threshold value, so that the wearable gateway selects the gateway mode according to the electric quantity threshold value.
S204, comparing the current electric quantity value with the determined electric quantity threshold value, if the current electric quantity value is lower than the determined electric quantity threshold value, selecting to close the WiFi access mode, and entering the step S205; if the current power value is higher than the determined power threshold, the WiFi access mode is selected to be kept on and the process returns to step S202 again.
Specifically, the portable gateway monitors its own power in real time, compares the current power with the power threshold determined in step S203, and selects the gateway mode of the portable gateway according to the comparison result. And if the current electric quantity value is higher than the determined electric quantity threshold value, selecting to keep starting the WiFi access mode, and continuously providing network access service for the terminal. If the current electric quantity value is lower than the determined electric quantity threshold value, the WiFi access mode is selected to be closed, network access service is not provided for the terminal any more, so that the terminal is disconnected from the portable gateway, and the terminal scans again and tries to access other gateways.
According to the steps, the electric quantity threshold value of the portable gateway is related to the probability of accessing the terminal to other gateways. When the power threshold is low, it indicates that the probability that the terminal accesses other gateways is low (that is, the probability that the terminal accesses other gateways in the current state is not high), and in general, the current power of the portable gateway is not lower than the power threshold, and WiFi access service can be provided for the terminal all the time, so that power consumption caused by frequent failure when the terminal continuously attempts to access other gateways is avoided. If the current power is lower than the determined power threshold, it indicates that the power of the gateway is not enough, in this case, although the possibility that the terminal accesses other gateways is not high, it is desirable that the terminal can try to access other gateways because the power of the gateway is low, so as to save the power of the gateway for the time and the time. When the power threshold is higher, it indicates that the probability that the terminal accesses other gateways is higher (i.e., the terminal is easier to access other gateways in the current state), and the current power of the portable gateway is easily lower than the power threshold, so that the portable gateway closes the WiFi access mode to cause the terminal to try to access other gateways, thereby saving the power of the portable gateway by using other gateways as much as possible. And if the current electric quantity of the portable gateway is higher than the electric quantity threshold value, the terminal can continuously access the portable gateway, although the possibility that the terminal accesses other gateways is high in the condition, the electric quantity of the portable gateway is sufficient, the terminal is allowed to continuously access the portable gateway, and the network interruption caused by switching the gateway can be avoided.
S205, judging whether the terminal accesses to other gateways after the WiFi access mode is selected to be closed, and selecting to open the WiFi access mode when the terminal is judged not to access to other gateways; and when the terminal is judged to have access to other gateways, the WiFi access mode is selected to be kept closed.
Specifically, after the portable gateway selects to close the WiFi access mode, the terminal cannot continue to access the portable gateway, disconnect the portable gateway from the terminal, and perform scanning to attempt to access other gateways. According to step S204, it is known that the current power of the wearable gateway is lower than the threshold power, and the power of the wearable gateway is not enough for the terminal to access, but the WiFi access mode is turned off by selecting, so that the terminal preferentially selects another gateway. Of course, the terminal is not necessarily able to determine access to other gateways. Therefore, preferably, in this embodiment, after the WiFi access mode is selected to be turned off, whether the terminal accesses to another gateway is determined, and whether the WiFi access mode is turned on is selected according to a determination result, so as to ensure that the terminal can always have a gateway to access.
Preferably, the step of determining whether the terminal accesses to another gateway specifically includes: and judging whether the connection state information of the terminal is received within preset time, if so, judging that the terminal has access to other gateways, otherwise, judging that the terminal does not have access to other gateways.
The connection state information may be ID information of a gateway successfully accessed to another gateway or accessed by the terminal, that is, the information is sent to the portable gateway after the terminal is successfully connected. Therefore, in the preset time, if the portable gateway receives the information, the portable gateway indicates that the terminal has accessed other gateways, and if the portable gateway does not receive the state information, the portable gateway indicates that the terminal has not accessed other gateways, so that whether the WiFi access mode is started or not is selected.
Preferably, another manner for determining whether the terminal accesses to another gateway may specifically include: and receiving feedback information of the terminal, and judging whether the terminal is accessed to other gateways or not according to the feedback information.
That is, the terminal may send the feedback information to the carry-on gateway regardless of whether the connection is successful or not. The feedback information is description information of the condition that the terminal accesses other gateways, for example, the terminal has accessed other gateways or the terminal does not access other gateways, success or failure, etc. And the portable gateway selects whether to start the WiFi access mode or not by judging the content of the feedback information.
In the gateway switching method provided in this embodiment, different power thresholds are determined according to different states of the portable gateway, and the WiFi access mode is selected by comparing the current power of the portable gateway with the power threshold. If the current electric quantity is lower than the electric quantity threshold value, the WiFi access mode is selected to be closed, the WiFi access service is not provided for the terminal, so that the terminal is preferentially accessed to other gateways, and the electric quantity consumption of the portable gateways is reduced for the occasional need. And after the WiFi access mode is closed, the connection condition of the terminal and other gateways can be judged, and if the terminal is not accessed into other gateways, the portable gateway can restart the WiFi access mode so that the terminal can be accessed into the portable gateway again. According to the gateway switching method provided by the embodiment, intelligent switching of the gateway according to different states can be realized, the endurance time of the portable gateway is prolonged, the frequency of switching the gateway by the terminal is reduced, and the terminal can be ensured to have the gateway to be accessed all the time.
