An embodiment of the present invention provides a network acquisition method, which is shown in fig. 1 and includes the following steps:
Specifically, the step 101 of acquiring the signal strength of the communication network having an association relationship with the terminal may be implemented by the terminal. The communication network associated with the terminal may be a mobile communication network in which the terminal is used to obtain non-speech services such as telephone service, data, and fax.
Specifically, the step 102 of determining the relationship between the signal strength of the communication network and the first preset threshold may be implemented by the terminal. The first preset threshold value can be obtained by performing a large number of experimental tests and practical application situations.
And 103, searching for the Wi-Fi hotspot signal if the signal intensity of the communication network is smaller than a first preset threshold value.
Specifically, if the signal strength of the communication network is smaller than the first preset threshold in step 103, searching for the Wi-Fi hotspot signal may be implemented by the terminal. When the Signal Strength (RSSI) of the communication network is less than a first preset threshold, if the Wi-Fi hotspot searching function of the terminal is turned off, the terminal may generate a control instruction to control the terminal to turn on the Wi-Fi hotspot searching function to start searching for Wi-Fi hotspot signals around the terminal, and if the Wi-Fi hotspot searching function of the terminal is turned on, the terminal directly searches for the Wi-Fi hotspot signals around the terminal.
And step 104, determining the optimal communication network by adopting a preset rule according to the relation between the Wi-Fi hotspot signal and a preset hotspot database, and registering the optimal communication network.
Specifically, the step 104 may be implemented by the terminal, according to the relationship between the Wi-Fi hotspot signal and the preset hotspot database, determining the optimal communication network by using the preset rule, and registering the optimal communication network to the optimal communication network. The preset hotspot database can be obtained by downloading the terminal from a server through a data network or a wireless network after the terminal is powered on.
According to the network acquisition method provided by the embodiment of the invention, the signal intensity of a communication network having an association relation with a terminal is acquired, the relation between the signal intensity of the communication network and a first preset threshold value is judged, if the signal intensity of the communication network is smaller than the first preset threshold value, a Wi-Fi hot spot signal is searched, and then according to the relation between the Wi-Fi hot spot signal and a preset hot spot database, a preset rule is adopted to determine the optimal communication network and register the optimal communication network to the optimal communication network; therefore, the terminal is at different communication network edges, when the signal intensity of the communication network is weak, the optimal communication network is selected through the preset rule and registered to the optimal communication network, the problem that the service performance of the terminal at the edge of the cell network is reduced in the prior art is solved, the terminal can be selected and reside on the communication network with stable wireless communication signals for a long time when the terminal is at the edge of the cell network, the service performance of the terminal at the edge of the cell network is improved, and the interaction capacity between the terminal and a user is improved.
An embodiment of the present invention provides a network acquisition method, which is shown in fig. 2 and includes the following steps:
Specifically, after the terminal is powered on every time, a Home Public Land Mobile Network (HPLMN) on the user identification card can be identified; the communication network comprises a first communication network and a second communication network, the first communication network can be a HPLMN corresponding to a user identity identification card of the terminal, such as a China Mobile communication network, a China telecom communication network and a China Unicom communication network, and the second communication network can be a roaming communication network signed with an operator providing the HPLMN. For example, when the terminal is near shenzhen and hong kong border, the terminal can generally receive the communication network of the chinese telecommunication and the hong kong roaming communication network at the same time, the terminal can obtain the signal strengths of the two communication networks, and the implementation manner of obtaining the signal strength of the communication network by the terminal may refer to the existing implementation manner, which is not described in detail herein.
Specifically, the terminal compares the magnitude relationship between the acquired signal strength of the communication network of the chinese telecommunication and the first preset threshold value, and also compares the magnitude relationship between the acquired signal strength of the hong kong roaming communication network and the first preset threshold value. It should be noted that the first preset threshold value for comparing the signal strength with the signal strength of the communication network of the china telecom and the first preset threshold value for comparing the signal strength with the signal strength of the hong kong roaming communication network may be the same or different, and may be determined according to specific situations.
It should be noted that, after the terminal determines the relationship between the signal strength of the communication network and the first preset threshold in step 202, step 203 to step 208, step 209, or step 210 may be selectively executed, when both the signal strength of the first communication network and the signal strength of the second communication network are less than the first preset threshold, step 203 to step 208 may be executed, when the signal strength of the first communication network is greater than or equal to the first preset threshold, step 209 may be executed, and when the signal strength of the first communication network is less than the first preset threshold and the signal strength of the second communication network is greater than or equal to the first preset threshold, step 210 may be executed;
and 203, if the signal intensity of the communication network is smaller than a first preset threshold value, searching the Wi-Fi hotspot signal by the terminal.
Specifically, if the signal strength of the communication network of the china telecom is smaller than a first preset threshold and the signal strength of the hong kong roaming communication network is smaller than the first preset threshold, the terminal may start to search for the Wi-Fi hotspot signal.
And step 204, the terminal acquires the Wi-Fi hotspot signal to obtain a first list.
The first list stores identification information of Wi-Fi hotspot signals.
Specifically, the terminal may search for the obtained relevant information of the Wi-Fi hotspot signal, including a Service Set Identifier (SSID), a Media Access Control (MAC) address, signal strength, and the like of the Wi-Fi hotspot signal, and may sort the obtained Wi-Fi hotspot signal according to a relationship from strong to weak or from weak to strong of the signal strength, and store the SSID, the MAC address, the signal strength, and the like of the corresponding Wi-Fi hotspot signal to obtain a first list, for example, the first list may be named as an apscan list. It should be noted that the terminal may also perform sorting processing according to other relevant information of the Wi-Fi hotspot signal and other sorting rules.
And step 205, the terminal selects the Wi-Fi hotspot signals which are the same as the identification information of the Wi-Fi hotspot signals in the preset hotspot database from the first list to obtain first Wi-Fi hotspot signals.
Specifically, the terminal may download, from the server, a preset hotspot database corresponding to the HPLMN of the terminal, that is, the same subscriber identity card, by using a mobile data network or a wireless communication network, where if the terminal determines the current location, the preset hotspot database acquired by the terminal may also be the preset hotspot database corresponding to the current location; the identification information of the Wi-Fi hotspot signals in the preset hotspot database can be MAC addresses of the Wi-Fi hotspot signals. The method includes the steps that an optimal Public Land Mobile Network (PLMN) near a Wi-Fi hotspot can be recorded in a preset hotspot database, the PLMN can be a communication Network provided by an operator, or a roaming Network signed with the operator, and the like, the optimal PLMN can be obtained by testing services such as a telephone voice service, a data traffic service and the like of the communication Network near the Wi-Fi hotspot, and the obtained specific stored content can include an SSID, an MAC address, the optimal PLMN and the like of the Wi-Fi hotspot. For example, the specific storage format of the preset hotspot database may be as shown in table 1, where the content stored in table 1 is mainly the preset hotspot database used by china telecom in shenzhen, serial No. 1 is a Wi-Fi hotspot deployed by china telecom in shenzhen, the best PLMN in the vicinity thereof is a china telecom communication network (46011), serial No. 2 is a Wi-Fi hotspot in hong kong in china, the best PLMN in the vicinity thereof is a hong kong roaming network (45403) signed with china telecom, serial No. 3 is a relatively fixed hotspot provided by a restaurant or hotel, and the best PLMN in the vicinity thereof is a china telecom communication network (46011). It should be noted that there may be multiple optimal PLMNs near these hotspots, and the terminal needs to obtain a corresponding preset hotspot database according to its HPLMN.
Table 1 preset hotspot database
| Serial number | SSID | MAC address | Optimal PLMN | Operator hot spot |
| 1 | ChinaNet | 4439C4389B22 | 46011 | Is that |
| 2 | HongKong001 | 4439C4389B24 | 45403 | Whether or not |
| 3 | TP-LINK-CD02 | BC469914D8F0 | 46011 | Whether or not |
| 4 | …… | …… | …… | …… |
Illustratively, the terminal may obtain a Wi-Fi hotspot signal in the APscanned list, which is the same as the MAC address in the preset hotspot database, to obtain a first Wi-Fi hotspot signal.
And step 206, the terminal sorts the first Wi-Fi hotspot signals according to the sequence from strong signal strength to weak signal strength to obtain a second list.
Specifically, the terminal may sort the first Wi-Fi hotspot signals in the order from strong to weak in signal strength, and obtain the second list, which may be named as an APfound list, where it should be noted that the APfound list is a subset of the apscan list. It should be noted that the terminal may also sequence the first Wi-Fi hotspot signals according to the sequence from weak signal strength to strong signal strength.
And step 207, the terminal acquires the first N Wi-Fi hotspot signals from the second list according to a preset selection rule.
And N is a positive integer and is less than or equal to the total number of the first Wi-Fi hotspot signals in the second list.
Specifically, the preset selection rule may be that the signal strength of the Wi-Fi hotspot signal in the second list satisfies a certain threshold, or some other selection rule method. If the terminal sorts the first Wi-Fi hotspot signals in the sequence from strong to weak, the terminal may select the first N first Wi-Fi hotspot signals from the APfound list, where the signal strength of the Wi-Fi hotspot signals satisfies a certain threshold, and if the terminal sorts the first Wi-Fi hotspot signals in the sequence from weak to strong, the terminal may select the last N first Wi-Fi hotspot signals from the APfound list, where the signal strength of the Wi-Fi hotspot signals satisfies the certain threshold.
And step 208, the terminal analyzes the first N ordered first Wi-Fi hotspot signals in the second list to obtain an optimal communication network and registers the optimal communication network.
Specifically, the terminal may perform classification analysis on the first N Wi-Fi hotspot signals in the selected and obtained APfound list according to the optimal PLMN corresponding to the Wi-Fi hotspot signals when the signal strength is ranked from strong to weak or the last N Wi-Fi hotspot signals in the ranked according to the signal strength from weak to strong, and compare relationships between different classified PLMNs to determine an optimal communication network, and after the optimal communication network is determined, the terminal may register in the optimal communication network, where a specific registration method may refer to the existing implementation technology and is not described in detail herein.
Specifically, if the signal strength of the HPLMN acquired by the terminal is greater than or equal to the first preset threshold, the terminal may select the HPLMN as the optimal communication network and register the HPLMN with the optimal communication network.
Specifically, if the signal intensity of the HPLMN acquired by the terminal is less than a first preset threshold and the signal intensity of the roaming communication network subscribed by the operator providing the HPLMN is greater than or equal to the first preset threshold, the terminal may select the roaming communication network subscribed by the operator providing the HPLMN as the optimal communication network and register the optimal communication network.
It should be noted that, for the explanation of the same steps or concepts in the present embodiment as in the other embodiments, reference may be made to the description in the other embodiments, and details are not described here.
According to the network acquisition method provided by the embodiment of the invention, the signal intensity of a communication network having an association relation with a terminal is acquired, the relation between the signal intensity of the communication network and a first preset threshold value is judged, if the signal intensity of the communication network is smaller than the first preset threshold value, a Wi-Fi hot spot signal is searched, and then according to the relation between the Wi-Fi hot spot signal and a preset hot spot database, a preset rule is adopted to determine the optimal communication network and register the optimal communication network to the optimal communication network; therefore, the terminal is at different communication network edges, when the signal intensity of the communication network is weak, the optimal communication network is selected through the preset rule and registered to the optimal communication network, the problem that the service performance of the terminal at the edge of the cell network is reduced in the prior art is solved, the terminal can be selected and reside on the communication network with stable wireless communication signals for a long time when the terminal is at the edge of the cell network, the service performance of the terminal at the edge of the cell network is improved, and the interaction capacity between the terminal and a user is improved.

Step 311, if the first value is greater than or equal to the second value, the terminal selects the first communication network as the best communication network and registers the first communication network.
In step 312, if the first value is smaller than the second value, the terminal selects the second communication network as the best communication network and registers to the second communication network.
Specifically, the method for obtaining the optimal communication network is not limited to the method introduced in step 308 to step 312, and may also be that the terminal obtains a signal intensity set of Wi-Fi hotspot signals of which the communication network corresponding to the first N sequenced first Wi-Fi hotspot signals in the second list is the first communication network, so as to obtain a first signal intensity set; the terminal acquires signal intensity sets of other Wi-Fi hotspot signals except the Wi-Fi hotspot signal corresponding to the first communication network from the N first Wi-Fi hotspot signals to obtain a second signal intensity set; comparing the magnitude relation between the signal strength with the maximum signal strength of the Wi-Fi hotspot signals in the first signal set and the signal strength with the maximum signal strength of the Wi-Fi hotspot signals in the second signal set, and if the signal strength with the maximum signal strength of the Wi-Fi hotspot signals in the first signal set is greater than or equal to the signal strength with the maximum signal strength of the Wi-Fi hotspot signals in the second signal set, selecting the first communication network as the best communication network; and if the signal intensity with the maximum signal intensity of the Wi-Fi hot spot signals in the first signal set is smaller than the signal intensity with the maximum signal intensity of the Wi-Fi hot spot signals in the second signal set, selecting the second communication network as the optimal communication network. The method for obtaining the best communication network can also be obtained by combining the methods from step 308 to step 312 with the above-mentioned methods, and can also be other effective selection methods.
Specifically, the preset time may be an empirical value determined through long-term experiments and actual use conditions, and may be 30 seconds, for example.
It should be noted that, when the terminal registers to the optimal communication network in step 313, after determining whether the communication service can be acquired through the optimal communication network within the preset time, the terminal may selectively perform steps 314 to 316 or steps 317 to 319, and may selectively perform steps 314 to 316 if the communication service can be acquired through the optimal communication network within the preset time, or may selectively perform steps 317 to 319 if the communication service cannot be acquired through the optimal communication network within the preset time;
and step 314, if the terminal can obtain the communication service through the optimal communication network within the preset time, obtaining a second Wi-Fi hotspot signal corresponding to the optimal communication network in the first list.
Specifically, if the terminal can obtain a telephone service or a data traffic service through the determined PLMN or roaming network within 30 seconds, the terminal selects a Wi-Fi hotspot signal corresponding to the PLMN or roaming network in the apscan list to obtain a second Wi-Fi hotspot signal.
Specifically, the terminal selects the Wi-Fi hotspot signal with the strongest type strength of the second Wi-Fi hotspot signal, and judges whether the Wi-Fi hotspot signal is stored in an APfound list or not.
And step 316, if the Wi-Fi hotspot signal with the strongest signal strength in the second Wi-Fi hotspot signals is not in the second list, the terminal acquires the identification information of the Wi-Fi hotspot signal with the strongest signal strength in the second Wi-Fi hotspot signals and adds the identification information to a preset hotspot database.
Specifically, if the Wi-Fi hotspot signal with the strongest type strength of the second Wi-Fi hotspot signal is stored in the APfound list, no processing is performed.
Specifically, the terminal may identify the number of the Wi-Fi hotspot signals according to the Wi-Fi hotspot signal division standard in table 2, where dBm is a unit of signal intensity and is a millimeter decibel watt in table 2. When the number of times that the terminal cannot obtain the communication service through the best communication network PLMN or the roaming network within 30 seconds is greater than the second preset threshold, the terminal may delete the Wi-Fi hotspot signals in the APfound list, in which the number of signal lattices corresponding to the best communication network PLMN or the roaming network exceeds 4, from the preset hotspot database.

| -85dBm≤RSSI<-75dBm | 2 |
| -90dBm≤RSSI<-85dBm | 1 |
| RSSI<-90dBm | 0 |
And step 320, if the signal intensity of the first communication network is greater than or equal to a first preset threshold, the terminal selects the first communication network as an optimal communication network and registers the optimal communication network.
In step 321, if the signal strength of the first communication network is smaller than the first preset threshold and the signal strength of the second communication network is greater than or equal to the first preset threshold, the terminal selects the second communication network as the optimal communication network and registers the optimal communication network.
