The restriction for technical solution provided in an embodiment of the present invention is not constituted, those of ordinary skill in the art are it is found that with newly answering
With the appearance of scene, technical solution provided in an embodiment of the present invention is equally applicable for similar technical problem.
Currently, most of terminals all have WLAN function.Terminal can by the WLAN hot spot near WLAN scanning discovery,
And " online " function is realized by establishing connection with the WLAN hot spot scanned.
Terminal carries out WLAN scanning after opening WLAN function, according to the interval duration of setting, when carrying out WLAN scanning,
User can perceive WLAN sweep spacing, such as: in user goes back home, the wifi function of mobile phone is opened, is connected in family
When WIFI hot spot, even if WIFI hot spot is to have turned on state, it is still necessary to it waits for a period of time and just can connect to the WIFI hot spot, this
The time that section waits is exactly WLAN scanning WIFI hot spot and establishes automatically the time of connection.
When carrying out WLAN scanning, there are two types of possible scenes, are as shown in Figure 1A terminal not within the scope of WLAN hot spot
Schematic diagram of a scenario, it will be understood that, terminal open WLAN function when where position exceed at a distance from WLAN hot spot
WLAN scanning distance, under the scene, no matter terminal carries out how many times WLAN scanning, can not all scan WLAN hot spot, until
Terminal enters within the scope of WLAN hot spot, could pass through WLAN scanning discovery WLAN hot spot and establish company with the WLAN hot spot of discovery
It connects, such as in the example above, user goes back home the middle WIFI hot spot that could connect oneself.As shown in Figure 1B, it is in for terminal
The schematic diagram of a scenario of WLAN hot spot range.
Obviously, when terminal is within the scope of WLAN hot spot, the more short then terminal of interval duration and WLAN hot spot of WLAN scanning
The used time for establishing connection is shorter, such as: a length of 1 second when interval, then after terminal enters WLAN hot spot range, it most 1 seconds can
To establish connection with the WLAN hot spot；If 5 minutes a length of when interval, if terminal has just carried out once before entering WLAN hot spot
WLAN scanning, has subsequently entered WLAN hot spot range, it means that terminal may after about 5 minutes could be with the WLAN
Hot spot establishes connection.
It is existing, as terminal can not the current scene locating for itself in region, thus between can not dynamically adjusting WLAN scanning
Every duration, in order to which balanced termination is found and establishes this problem of time and system power dissipation consumed by connection with WLAN hot spot,
Developer usually sets the WLAN of the terminal interval duration scanned to the value of fixed " neither big nor small ", from number
From the point of view of angle, it appears that it is to have reached the balance of the two, however in fact, for the scale of construction of terminal, the scanning side of existing WLAN
Formula will waste huge time resource.
Further, after terminal discovery WLAN hot spot, connection can only be established automatically with the WLAN hot spot saved.Therefore, originally
Inventive embodiments propose a kind of mode for adjusting WLAN sweep spacing, and the band of position for the WLAN hot spot having connected is recorded
Come, judge current location whether in the band of position of the WLAN hot spot of record, and according to judging result dynamic adjustment WLAN sweep
Retouch interval.
The embodiment of the invention provides a kind of schemes of dynamic adjustment WLAN sweep spacing, including near how terminal to know
Whether there is attachable WLAN hot spot, and is with or without after attachable WLAN hot spot near having determined between WLAN scanning
Every dynamic adjustment can be established as early as possible with WLAN hot spot so that in the case that terminal nearby has attachable WLAN hot spot
Connection reduces terminal discovery and establishes the time of WLAN connection；Or nearby without attachable WLAN hot spot in the case where,
Unnecessary WLAN scanning times are reduced, system power dissipation is reduced.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
As shown in Fig. 2, provided in an embodiment of the present invention is a kind of method for adjusting WLAN sweep spacing, specifically include following
Step:
Step S20: after terminal is in WLAN open state, judged whether according to current location information in target area
It is interior；Wherein the target area is the region where when the terminal of terminal record is in WLAN connection status；
Step S21: if in target area, the terminal carries out WLAN scanning according to the first default sweep spacing；If
Not in target area, then the terminal carries out WLAN scanning according to the second default sweep spacing；Wherein, it described first default sweeps
It retouches interval and is less than the described second default sweep spacing.
Through the above scheme, after terminal and WLAN hot spot establish connection, by the information of the WLAN hot spot and with the WLAN
Region (i.e. target position region) where when hot spot establishes connection is saved, and after terminal opens WLAN function, judgement is current
Whether position is in the target position region of record, if, then it is assumed that terminal is in the region of the WLAN hot spot saved
In range, terminal carries out WLAN scanning using shorter time interval；It has been saved if it was not then thinking that terminal is not in
In the regional scope of WLAN hot spot, terminal carries out WLAN scanning using longer time interval, so that terminal, which nearby has, to be connected
In the case where the WLAN hot spot connect, connection can be established with the WLAN hot spot as early as possible, reduces the terminal waiting time；Or do not have nearby
In the case where having attachable WLAN hot spot, unnecessary WLAN scanning times are reduced, reduce system power dissipation.
