Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the present invention relates to a method for restoring a network, which is applied to a server, and the present embodiment can realize a fast network return in a scenario where a terminal is out of service (oos for short). The terminal can be a mobile phone, a tablet computer and other network-enabled devices. In this embodiment and the following embodiments, the terminal is a mobile phone as an example, but the present invention is not limited to this. The following describes implementation details of the method for restoring a network according to the present embodiment in detail, and the following is only provided for easy understanding and is not necessary for implementing the present embodiment.
As shown in fig. 1, the method for restoring a network in this embodiment may specifically include:
step 101: the current location of the terminal is determined.
Specifically, the server may determine the current location of the mobile phone according to a Global Positioning System (GPS), for example, the mobile phone may detect the current location of the mobile phone itself and send the detected current location to the server, so that the server may obtain the current location of the mobile phone.
In an example, the server may also periodically determine the current location of the mobile phone, for example, the mobile phone may report the current location to the server at intervals, and the time of each reporting interval may be set by a person skilled in the art according to actual needs, for example, may be set to several seconds, but this embodiment is not limited to this specifically.
Step 102: and determining the standby frequency point corresponding to the current position of the terminal according to the current position of the terminal.
The signal intensity of the standby frequency point is greater than a preset threshold, the size of the preset threshold can be set by a person skilled in the art according to actual needs, and the purpose is to screen out a frequency point with a better signal in the frequency point corresponding to the current position of the terminal. It can be understood that, in a certain location area, a plurality of selectable frequency points are generally distributed, and the signal intensities of the plurality of selectable frequency points may have differences, and a mobile phone may use one of the frequency points as a working frequency point to access a network. In addition, different position areas can be divided in advance so as to distinguish frequency points corresponding to different positions.
Specifically, a signal detector can be deployed in a spatial position in advance, the signal detector can be used for detecting the signal intensity of the frequency points corresponding to different positions, the signal detector reports the signal intensity of the frequency points corresponding to different positions obtained through detection to a server, so that the server can obtain the signal intensity of the frequency points corresponding to different positions, the signal intensity of each frequency point corresponding to the current position of the mobile phone is obtained, then the signal intensity of each frequency point corresponding to the current position of the mobile phone can be judged, and the frequency points with the signal intensity larger than a preset threshold value are screened out to serve as standby frequency points corresponding to the current position of the mobile phone. It can be understood that, as the current position of the mobile phone changes, the standby frequency point corresponding to the current position of the mobile phone determined by the server may also change.
In an example, the spare frequency point corresponding to the current position of the mobile phone may also be a frequency point with the highest signal strength, i.e., a frequency point with the best signal, among the frequency points corresponding to the current position of the mobile phone. In a specific implementation, the standby frequency point may be a plurality of frequency points with signal strength greater than a preset threshold in the frequency point corresponding to the current position of the mobile phone, or may be one frequency point with the largest signal strength, which is not specifically limited in this embodiment.
In one example, a signal detector may be disposed in each location area that is divided in advance, and the signal detector is responsible for detecting the signal strength of each frequency point corresponding to the disposed area. In another example, a signal detector may be deployed in the location areas, and the signal detector may detect the signal strength of each frequency point corresponding to each of the locations.
In an example, the signal detector may detect the signal intensity of each frequency point corresponding to different positions at regular time, and report the detected signal intensity of each frequency point to the server at regular time. For example, the signal detector may detect the signal intensity of each frequency point corresponding to different positions every few seconds, and then report the detected signal intensity of each frequency point to the server. In another example, the signal detector may also detect the signal intensity of each frequency point corresponding to different positions in real time, and then report the signal intensity of each frequency point detected at the current time to the server every few seconds.
Step 103: and periodically sending the information of the standby frequency points corresponding to the current position of the terminal to the terminal.
After receiving the information of the standby frequency point sent by the server, if the terminal detects that the terminal is in a no-service state, the terminal initiates network searching registration according to the information of the standby frequency point received last time. The out-of-service state can be understood as no signal or the signal strength of the current access frequency point of the terminal is 0. That is, if the mobile phone suddenly has no signal, or the signal intensity of the current working frequency point of the mobile phone suddenly becomes 0, the mobile phone may initiate network searching registration according to the information of the standby frequency point sent by the server last time. The network searching and registering can be understood as that the cell searching is carried out by using a frequency point with better signal by the mobile phone, and a cell meeting the cell residence criterion is selected to access the network and is registered in the resident cell. It should be noted that, since the technical means used for implementing the network searching registration is the prior art, and those skilled in the art can implement the method according to the related art, this embodiment will not be described in detail.
Specifically, the server can send the information of the standby frequency point corresponding to the current position of the mobile phone to the mobile phone at intervals. The interval time for the server to send the information of the spare frequency point to the mobile phone can be set by the technical personnel in the field according to the actual needs. In an example, if the signal detector reports the signal strength of each frequency point corresponding to different positions to the server at regular time, the server may select the standby frequency point corresponding to the current position of the mobile phone after receiving each frequency point corresponding to different positions reported by the signal detector, and send the information of the selected standby frequency point to the mobile phone. In another example, if the signal detector reports the signal strength of each frequency point corresponding to different positions to the server in real time, the server may screen out the standby frequency point corresponding to the current position of the mobile phone at intervals after receiving each frequency point corresponding to different positions reported by the signal detector, and send the information of the selected standby frequency point to the mobile phone. It can be understood that, if the interval time for the server to send the information of the standby frequency point to the mobile phone is extremely short, the server may also be considered to send the information of the standby frequency point to the mobile phone in real time.
In an example, before the server issues the information of the standby frequency point to the mobile phone this time, the server may further compare the information of the standby frequency point to be issued this time with the information of the standby frequency point issued last time, if the information of the standby frequency point issued twice is the same, then this time may not be sent, and the information of the standby frequency point corresponding to the current position of the mobile phone is issued to the mobile phone again knowing that the acquired information of the standby frequency point corresponding to the current position of the mobile phone is different from the information of the standby frequency point issued last time.
In one example, the mobile phone may store the information of the spare frequency point sent by the server when receiving the information of the spare frequency point, so as to initiate network searching registration by using the stored information of the spare frequency point when the mobile phone suddenly fails to receive a signal. The mobile phone can delete the information of the standby frequency point sent by the server last time after receiving the information of the standby frequency point sent by the server this time, that is, the information of the standby frequency point sent by the server last time is always stored in the mobile phone.
In an example, if the information of the standby frequency point sent by the server to the mobile phone includes multiple frequency points, that is, the number of better frequency points sent by the server to the mobile phone is multiple. Then, when the mobile phone suddenly has no service, a plurality of frequency points with better signals can be processed from large to small according to the signal intensity. For example, network searching registration is initiated according to the frequency point with the maximum signal intensity, if network searching registration fails, network searching registration can be initiated according to the frequency point ranked as the second position according to the signal intensity, and network searching registration is successful according to the above process.
It can be understood that, in the network stage of the mobile phone, the server may issue frequency points with good signals at every T s according to the GPS location of the mobile phone, and considering that the mobile phone does not move in a large range in a short time, when the mobile phone suddenly encounters a network fault, that is, suddenly has no signal and is in a no-service state, the mobile phone may initiate a network searching registration by using information of the backup frequency point issued last time, thereby quickly recovering the network. T may be set according to actual needs, and this embodiment is not particularly limited to this.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, in the embodiment, the server periodically sends the information of the standby frequency points corresponding to the current position of the terminal to the terminal, and the standby frequency points are all frequency points with better signals because the signal intensity of the standby frequency points is greater than the preset threshold value. Considering that the position of the terminal cannot move in a large range in a short time, when the terminal is suddenly in a no-service state, the standby frequency point sent by the server received last time can be adopted to initiate network searching registration, which is beneficial to quickly restoring the network, namely beneficial to quickly restoring the network service of the terminal, and avoiding the influence of long duration time of the no-service state on the normal use of the terminal by a user. Meanwhile, the implementation mode of the invention is beneficial to ensuring the stability of the network to a certain extent and can be well applied to scenes with high requirements on network delay.
A second embodiment of the present invention relates to a method of restoring a network. As shown in fig. 2, the method for restoring a network in this embodiment may specifically include:
step 201: the current location of the terminal is determined.
Step 201 is substantially the same as step 101 in the first embodiment, and is not described herein again to avoid repetition.
Step 202: and receiving the signal intensity of the frequency points corresponding to different positions reported by the pre-deployed signal detector.
The specific implementation manner of step 202 is described in detail in step 102 in the first embodiment, and is not described herein again to avoid repetition.
Step 203: and storing the frequency points at different positions and corresponding to different positions in a key value pair mode.
In one example, the saving of the form of key-value pairs may be understood as: and storing the frequency points corresponding to the position A and the position B as a key value pair, namely storing the frequency points corresponding to one position as a key value pair. It can be understood that the number of the frequency points corresponding to one position may be one or multiple, that is, one frequency point corresponding to the position a and one frequency point corresponding to the position a may be stored in one key value pair, and also the position a and multiple frequency points corresponding to the position a may be stored in one key value pair.
In another example, the signal strengths of the frequency points stored in the key value pair may all be greater than a preset threshold, that is, the frequency points stored in the key value pair are all frequency points with better signals. For example, the frequency points corresponding to the position a include a frequency point 1, a frequency point 2, and a frequency point 3, but it is assumed that only the signal intensity of the frequency point 3 is greater than a preset threshold value among the three frequency points, and what is stored in the key value pair corresponding to the position a is the position a and the frequency point 3.
Step 204: and inquiring the key value pair corresponding to the current position of the terminal according to the stored key value pair.
It can be understood that, since the server stores key value pairs corresponding to different positions, the key value pair corresponding to the current position of the terminal can be queried in the key value pair stored in the server according to the current position of the terminal.
Step 205: and determining the spare frequency point corresponding to the current position of the terminal according to the inquired key value pair.
Specifically, each key value pair comprises a position and a frequency point corresponding to the position, so that the frequency point corresponding to the current position of the terminal can be determined according to the inquired key value pair.
In an example, if the size of the signal strength of the frequency point in the key value pair stored by the server is not limited, the queried key value pair corresponding to the current position of the terminal may include multiple frequency points, and the multiple frequency points may include a frequency point with a good signal and a frequency point with a poor signal. At this time, the server may screen out, from the plurality of frequency points in the queried key value pair, a frequency point having a signal strength greater than a preset threshold value as a standby frequency point corresponding to the current position of the terminal.
In another example, if the size of the signal intensity of the frequency point in the key value pair stored by the server is limited, that is, the signal intensity of the frequency point in the key value pair is greater than the preset threshold, the inquired frequency points with better signals are included in the key value pair corresponding to the current position of the terminal, and the server can directly determine the frequency point in the inquired key value pair as the spare frequency point.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Step 206: and periodically sending the information of the standby frequency points corresponding to the current position of the terminal to the terminal.
Step 206 is substantially the same as step 103 in the first embodiment, and is not repeated here.
Compared with the prior art, in the embodiment, the frequency points corresponding to different positions are stored in the form of key value pairs, so that the key value pairs corresponding to the position of the terminal are conveniently found, and the information of the standby frequency points corresponding to the position of the terminal can be quickly and accurately obtained. Moreover, the stored key values are all frequency points with better signals, which is beneficial to saving the storage space and simultaneously facilitates and simplifies the search of the spare frequency points corresponding to the position of the terminal in the subsequent process.
A third embodiment of the present invention relates to a method for restoring a network, which is applied to a terminal, and as shown in fig. 3, the method includes:
step 301: and receiving information of the standby frequency point corresponding to the current position of the terminal periodically sent by the server.
The standby frequency point is determined by the server according to the current position of the terminal and corresponds to the current position of the terminal, and the signal intensity of the standby frequency point is greater than a preset threshold value.
Step 302: and when the terminal is detected to be in a non-service state, initiating network searching registration according to the information of the standby frequency point received last time.
It is to be noted that the method of restoring a network according to the present embodiment is applied to a terminal, and the methods of restoring a network according to the first and second embodiments are applied to a server. Since the first and second embodiments correspond to the present embodiment, the present embodiment can be implemented in cooperation with the first and second embodiments.

Accordingly, the related-art details mentioned in the present embodiment can be applied to the first and second embodiments.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
