The mode that the intelligent terminal accesses the WLAN hotspot has the characteristics of low cost, low expense and high data transmission speed.
At present, when the intelligent terminal accesses the WLAN hotspot, a user needs to manually turn on a WLAN switch, and after the WLAN switch is turned on, the intelligent terminal can access the WLAN hotspot. If the WLAN switch is in the off state, even if the intelligent terminal enters the saved hotspot range where the internet can be accessed, the intelligent terminal cannot establish the WLAN connection because the WLAN switch is in the off state. At present, the intelligent terminal needs to be manually operated by a user to establish a WLAN connection mode, and when the intelligent terminal enters an available hotspot range, if the user does not turn on a WLAM hotspot switch in time, the intelligent terminal cannot access a WLAN hotspot in time, so that the consumption of the cellular network data traffic of the intelligent terminal is caused.
In summary, the current access method of the terminal to the WLAN hotspot is not flexible enough, which may cause consumption of data traffic of the cellular network.

Detailed Description
The terminal of the embodiment of the present invention may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. The terminal of the embodiment of the invention has the function of accessing the WLAN hotspot.
When the WLAN of the terminal is closed, the terminal judges whether the currently accessed base station is contained in the first type base station set; the base stations included in the first type base station set are base stations accessed when the terminal historically and successfully establishes WLAN connection; if so, the terminal starts hotspot scanning; according to the embodiment of the invention, when the WLAN of the terminal is in a closed state, if the base station which is accessed by the terminal currently is determined to be contained in the first type base station set, the terminal starts the hot spot scanning, so that the terminal can automatically start the hot spot scanning when the condition is met in the closed state of the WLAN of the terminal.
After starting hotspot scanning, a terminal scans available hotspots contained in a first type hotspot set, and then the terminal establishes WLAN connection with the available hotspots; the hot spots included in the first type of hot spot set are hot spots which are accessed successfully by the terminal in history; after the available hotspots in the first-class hotspot set are scanned, the embodiment of the invention can automatically access the available hotspots to successfully establish WLAN connection.
Therefore, according to the WLAN connection method for the terminal provided in the embodiment of the present invention, when the terminal is in a WLAN off state, the terminal determines that the currently accessed base station is included in the first class base station set, the terminal can automatically start WLAN scanning, and after an available hotspot is scanned, the terminal can establish WLAN connection with the available hotspot, so as to avoid a problem of cellular network data traffic consumption of the intelligent terminal due to the fact that the intelligent terminal cannot access the WLAN hotspot in time because a user does not turn on a WLAM hotspot switch in time.
It should be noted that, the terminal of the embodiment of the present invention stores a first type base station set and a first type hot spot set; the base stations in the first type of base station set are base stations accessed when the terminal historically and successfully establishes the WLAN connection, and the hotspots in the first type of hotspot set are hotspots accessed successfully by the terminal historically.
For example, the first type of base station set includes base station a, base station B, base station C, and base station D; the terminal successfully establishes a WLAN connection when accessing base station a, the terminal successfully establishes a WLAN connection when accessing base station B, the terminal successfully establishes a WLAN connection when accessing base station C, and the terminal successfully establishes a WLAN connection when accessing base station D.
The hot spots in the first type of hot spot set comprise a hot spot 1, a hot spot 2, a hot spot 3, a hot spot 4, a hot spot 5, a hot spot 6 and a hot spot 7; the hotspot 1, the hotspot 2, the hotspot 3, the hotspot 4, the hotspot 5, the hotspot 6 and the hotspot 7 are all hotspots to which the terminal has successfully accessed.
It should be noted here that, when the terminal stores the first type of base station set, each base station is uniquely identified by the identity of the base station; the identity of the base station includes Lac (location area code) and CellId (cell base station identity code). When the terminal stores the first type of hot spot set, each hot spot is uniquely identified through the identity identification of the hot spot; the identity of the hotspot includes SSID (hotspot name) and Security, the Security value is an integer, and the value is defined as: a 0-unencrypted hotspot, a 1-WEP encrypted hotspot, a 2-PSK encrypted hotspot, a 4-WAPI _ PSK encrypted hotspot, and a 5-WAPI _ CERT encrypted hotspot.
For example, the base station a in the first type base station set may be stored in the format shown in fig. 1; wherein, the Lac of the base station A is 21507, and the CellId of the base station A is 56667915. The hotspot 1 in the first type hotspot set can be stored in the format shown in fig. 2; wherein, SSID of X _2019 indicates that the name of the hot spot 1 is X _2019, and Security of 2 indicates that the hot spot 1 adopts PSK encryption.
The first type base station set and the first type hot spot set stored by the terminal are continuously updated, and the time for updating the first type base station set and the first type hot spot set by the terminal comprises the following steps: when the terminal successfully establishes the WLAN connection, and when the base station roams in the WLAN connection state. The following are described separately:
1. the terminal successfully establishes a WLAN connection.
It should be noted that the terminal establishes the WLAN connection by manually turning on the WLAN switch for the user, and successfully establishing the WLAN connection according to the user operation.
After the AutoWifi service receives the network connection state CHANGE broadcast (for example, the network connection state CHANGE broadcast is CONNECTIVITY _ CHANGE), if the network is determined to be in the connected state, the CONNECTIVITY detection is performed on the connected network. If the detection result is that the network can be accessed, obtaining the Lac and the CellId of the current access base station through a getCellLocation () interface; if the first type base station set does not have the base station which is accessed currently, the base station which is accessed currently is added into the first type base station set; and acquiring the SSID and the Security of the current access hotspot, and adding the current access hotspot into the first type hotspot set if the first type hotspot set does not have the current access hotspot. And if the first-class hotspot set comprises the currently accessed hotspot, deleting the currently accessed hotspot from the first-class hotspot set.
2. The terminal roams the base station in the WLAN connection state.
It should be noted that, at such an occasion, it needs to be satisfied that the terminal detects that the accessed base station changes, and the current terminal is in the WLAN connection state.
When the AutoWifiService receives the callback of the CHANGE of the base station (for example, the callback of the CHANGE of the base station is CELL _ LOCATION _ CHANGE), the terminal acquires the Lac and the CellId of the current access base station, then judges whether the current WLAN is in a connection state, and if the current WLAN is in the connection state, the terminal acquires the SSID and the Security of the current connection hotspot; and then updating the currently accessed base station and the currently connected hot spot into the first type base station set and the first type hot spot set respectively.
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. 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.
An embodiment of the present invention provides a WLAN connection method for a terminal, and as shown in fig. 3, the method includes:
It should be noted that the first type base station set and the first type hotspot set in the embodiment of the present invention may be generated in the above manner.
In an optional manner, the terminal stores the first type base station set and the first type hotspot set in the following manner:
wherein, for example, X0、Y0Is the identity of base station A, M0、N0The terminal is the identity of the hotspot 1, and when the terminal accesses the base station A, the WLAN connection with the hotspot 1 is established; x1、Y1Is the identity of base station B, M1、N1The terminal is the identity of the hotspot 2 and establishes WLAN connection with the hotspot 2 when the terminal accesses the base station B; x2、Y2Is the identity of base station C, M2、N2The terminal is the identity of the hotspot 3 and establishes WLAN connection with the hotspot 3 when the terminal accesses the base station C; x3、Y3Is the identity of base station D, M3、N3The terminal is the identity of the hotspot 4 and establishes WLAN connection with the hotspot 4 when the terminal accesses the base station D; x4、Y4Is the identity of base station E, M4、N4The terminal is the identity of the hotspot 5 and establishes WLAN connection with the hotspot 5 when the terminal accesses the base station E; x5、Y5Is the identity of base station F, M5、N5The terminal is the identity of the hotspot 6 and establishes WLAN connection with the hotspot 6 when the terminal accesses the base station F; x6、Y6Is the identity of base station G, M6、N6Is the identity of the hotspot 7 and establishes a WLAN connection with the hotspot 7 when the terminal accesses the base station G.
In step 301, the terminal determines whether the currently accessed base station is in the first class base station set at an occasion including, but not limited to:
after determining that the accessed base station is changed, the terminal judges whether the currently accessed base station is contained in the first type base station set; and/or
The terminal periodically detects whether the base station accessed currently is contained in the first type base station set.
The terminal judges whether the currently accessed base station is contained in the first type base station set, if so, the terminal starts hot spot scanning; if not, the terminal receives a first operation instruction for establishing the WLAN connection triggered by the user and then establishes the WLAN connection with the hotspot.
It should be noted here that the first operation instruction triggered by the user to establish the WLAN connection includes, but is not limited to:
an operation instruction for starting the WLAN triggered by a user;
and the user triggers an operation instruction for establishing WLAN connection with the available hot spot.
After receiving a WLAN operation starting instruction triggered by a user, the terminal starts hotspot scanning, and after scanning available hotspots, the terminal automatically establishes connection with the available hotspots; or after the available hot spot is scanned, the terminal receives an operation instruction for establishing the WLAN connection with the hot spot, which is triggered by the user, and then establishes the connection with the available hot spot.
An optional implementation manner is that after the terminal establishes the WLAN connection with the hotspot according to a first operation instruction for establishing the WLAN connection triggered by the user, the currently accessed base station is updated to the first class base station set, and the currently connected hotspot is updated to the first class hotspot set.
When the currently accessed base station is not in the first-class base station set, but the terminal establishes the WLAN connection with the hotspot according to the operation of the user, the currently accessed base station is the first-class base station, and the terminal updates the currently accessed base station to the first-class base station set, so that the first-class base station in the first-class base station set can be ensured to be continuously updated.
It should be noted that, before updating the currently connected hotspot to the first-type hotspot set, an optional manner is that the terminal determines whether the currently connected hotspot is in the first-type hotspot set, if so, the first-type hotspot set is not updated, and if not, the currently connected hotspot is updated to the first-type hotspot set.
In addition, in the embodiment of the invention, when the terminal is in the WLAN connection state, if a second operation instruction of closing the WLAN connection by the user is received, the terminal disconnects the WLAN connection;
for example, if the terminal detects that the user manually turns off the WLAN switch, the terminal disconnects the WLAN connection.
And the terminal records the current position and takes the current position as an area which does not allow the terminal to establish the WLAN connection. And when the terminal moves to the current position next time, the terminal is prevented from automatically starting WLAN scanning and establishing WLAN connection.
After the terminal receives a second operation instruction of closing the WLAN connection by the user and disconnects the WLAN connection, the terminal represents the current position by recording the currently accessed base station and the currently scanned hot spot, and the current position is taken as an area where the terminal is not allowed to establish the WLAN connection.
And the terminal is used as a second type of base station when receiving a second operation instruction for closing the WLAN connection by the user in the WLAN connection state, and the terminal is used as a second type of hotspot when receiving the operation for closing the WLAN connection by the user in the WLAN connection state.
It should be noted here that the terminal uses the MAC address of the hotspot to identify the scanned hotspot of the second type.
The terminal may avoid automatically establishing a WLAN connection at the current location in the following way:
in the first mode, the terminal deletes the second type base station in the first type base station set and deletes the second type hotspot in the first type hotspot set.
In implementation, in a WLAN connection state of the terminal, if the terminal receives a second operation instruction for closing the WLAN connection of the user, the terminal determines a currently accessed base station, and the terminal starts hotspot scanning to determine a hotspot which can be scanned; the terminal judges whether the currently accessed base station is in the first type base station set or not, and if so, the currently accessed base station is deleted from the first type base station set; and the terminal judges whether the scanned hot spot is in the first-class hot spot set or not, and if so, deletes the scanned hot spot from the first-class hot spot set.
For example, after receiving a second operation instruction for closing WLAN connection by a user, the terminal determines that a currently accessed base station is a base station a, and hotspots which can be currently scanned include a hotspot 1, a hotspot 2 and a hotspot 3; when the first type base station set comprises the base station A, the terminal deletes the base station A from the first type base station set; and if the hotspot 1 is in the first-type hotspot set, deleting the hotspot 1 from the first-type hotspot set, or if the hotspot 1, the hotspot 2 and the hotspot 3 are in the first-type hotspot set, deleting the hotspot 1, the hotspot 2 and the hotspot 3 from the first-type hotspot set.
By adopting the mode, neither the base station in the first type base station set nor the hot spot in the first type hot spot set is in the area where the terminal is not allowed to establish the WLAN connection, so that the terminal can be ensured to accurately establish the WLAN connection.
In a second mode, the terminal stores the base stations accessed when a second operation instruction of closing WLAN connection of the user is received into a second type base station set, starts hotspot scanning and stores the scanned hotspots into the second type hotspot set; and the terminal determines that the accessed base station is not in the second-class base station set and the scanned hot spot is not in the second-class hot spot set before establishing the WLAN connection.
The base stations included in the second type of base station set are base stations accessed when receiving a second operation instruction of closing WLAN connection by a user; the hotspots included in the second type of hotspot set are hotspots which can be scanned when an operation instruction of closing the WLAN connection by the user is received.
In implementation, the terminal stores Lac and CellId of the base station in a second type hotspot set to identify a second type base station; and the terminal stores the MAC address of the hot spot in a second hot spot set to identify the second hot spot.
It should be noted that, when the base station accessed by the terminal is not in the second type base station set and the hot spot scanned by the terminal is not in the second type hot spot set, it is determined that the current location of the terminal does not belong to an area where the terminal is not allowed to establish the WLAN connection.
In this manner, an optional terminal WLAN connection method is:
when the WLAN of the terminal is closed, the terminal judges whether the currently accessed base station is contained in the first base station set, if so, the terminal determines that the currently accessed base station is not contained in the second base station set, and the terminal starts hotspot scanning; and after scanning available hotspots contained in the first type of hotspot set and determining that all the scanned hotspots are not contained in the second type of hotspot set by the terminal, the terminal establishes WLAN connection with the available hotspots.
For example, after the base station accessed by the terminal is changed from the base station a to the base station B, the terminal determines that the currently accessed base station B is included in the first type base station set. Assume that the second set of base stations includes: base station D, base station E; the terminal determines that the base station B is not included in the second type set of base stations, and then the terminal starts hotspot scanning. If the scanned hot spots comprise a hot spot 5, a hot spot 6 and a hot spot 7; assume that the second category of hotspot sets includes: the terminal determines that none of the scanned hotspots is in the second type hotspot set, and then the terminal establishes a WLAN connection with an available hotspot in the first type hotspot set. For another example, assume that the second category of hotspot sets includes: the terminal determines that the scanned hotspot 7 is included in the second type of hotspot set, and then determines that the terminal cannot establish a WLAN connection at the current position.
One optional mode is that after the terminal establishes a WLAN connection with an available hotspot, the terminal detects the network quality of the available hotspot; and when the network quality is lower than a preset threshold value, the terminal deletes the available hotspot from the first hotspot set.
After the terminal establishes the WLAN connection, the network quality of the accessed hot spot needs to be detected, and the available hot spot is deleted from the first hot spot set when the network quality is lower than the preset threshold value, so that the available hot spots in the first hot spot set are guaranteed to be the hot spots with better network quality, and the problem that the terminal accesses the available hot spots with poor network quality when the WLAN is established is avoided.
In implementation, the network quality of the available hotspot may be the network speed, the terminal detects the network speed of the available hotspot, and when the network speed is lower than a preset threshold, the terminal deletes the available hotspot from the first hotspot set.
As shown in fig. 4, a complete flow chart of WLAN connection of the terminal according to the embodiment of the present invention is shown.
and the base stations included in the first type of base station set are the base stations accessed when the terminal successfully establishes the WLAN connection historically.
and the base stations included in the second type of base station set are base stations accessed when receiving an operation instruction of closing the WLAN connection by a user.
the hotspots contained in the second type of hotspot set are hotspots which can be scanned when the terminal receives an operation instruction of closing the WLAN connection by the user.
and the hot spots contained in the first type of hot spot set are hot spots which are successfully accessed by the terminal in history.
And step 406, the terminal establishes a WLAN connection with the available hotspot.
Based on the same inventive concept, the embodiment of the present invention further provides a terminal, and since the principle of solving the problem of the terminal is similar to the method for determining the WLAN connection of the terminal in the embodiment of the present invention, the implementation of the terminal may refer to the implementation of the method, and repeated details are not repeated.

if yes, starting hot spot scanning;
after available hotspots contained in the first type hotspot set are scanned, establishing WLAN connection with the available hotspots; and the hot spots contained in the first-class hot spot set are hot spots which are accessed successfully by the terminal in history.
