Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to still do not have at present effective method or system can solve terminal how when adhere to access point but unsuccessful login proceed the problem of data service, provide a kind of terminal method, device and terminal of switching of intelligence between access points.
As shown in Figure 1, a kind of terminal intelligent method switched between access points of the embodiment of the present invention, described method comprises:
Step 11, has no progeny in the connection of described terminal and the first access point is passive, selects the second access point to carry out trial access, and the priority-level of wherein said first access point is higher than the priority-level of described second access point;
When normal condition user uses WLAN business, the many meetings of terminal are automatically adhered to, are logged in the highest access point of priority-level, and often directly can complete login due to the memory function of login password, carry out data service.But in particular cases, due to terminal constantly move away from this access point or other burst reason cause current signal conditions cannot ensure again to communicate with minimum speed limit between this terminal with this access point, thus can there is the phenomenon of " passive disconnection " in terminal.Have no progeny in this terminal is passive, according to step 11, after this terminal " passive disconnection ", select the lower access point of priority-level to carry out trial access.
Step 12, successfully adheres to described second access point in described terminal, during described second access point of unsuccessful login, disconnects the attachment state of described terminal and described second access point;
Should recognize, the access of terminal and access point comprises to be adhered to and logs in, and under only having all successful situation of attachment, login, is only successful access.
Step 13, reselects access point and attempts access.
The priority-level of the second access point, because lower than the first access point, is not used by user usually, after being attached to the second access point, also needs user manually to initiate to log in.And for originally automatically having logined successfully at the first access point and successfully initiated the user of data service, may not realize the second access point being attached to and needing manual entry, and do not initiate to log at the second access point all the time---for this kind of user, just feel and cannot continue data service suddenly, and due to do not recognize change to need the second access point of manual entry and to provide the first access point operator initiate complain.And, if user does not log in, and adhere to and successfully can take access point IP with regard to expression always, make the real user needed not have IP to use, cause the wasting of resources.
In embodiments of the present invention, in order to avoid the situation of meaningless complaint and the wasting of resources occurs, successfully adhere to the second access point according to terminal in step 12, during unsuccessful login the second access point, just initiatively disconnect the connection attachment state with the second access point.Now, terminal reenters the state of not yet adhering to any access point.Then according to step 13, reselect access point and attempt access.
Therefore, the method for the embodiment of the present invention, achieve when adhere to access point but unsuccessful login can reselect access point, proceed data service, discharge the focus IP that cannot log in simultaneously, avoid meaningless complaint and the waste of resource.
As shown in Figure 2, in an embodiment of the present invention, step 12 comprises:
Step 121, after described terminal successfully adheres to described second access point, obtains described terminal wait and logs in duration value T;
Step 122, logs in duration value T in described wait and reaches wait login duration higher limit T
maxtime, if described second access point of the unsuccessful login of described terminal, then disconnect the attachment state of described terminal and described second access point.
By above-mentioned steps, log in duration value T according to the wait obtained and reaching wait login duration higher limit T
maxtime, Successful login second access point, the then attachment state of disconnected end and the second access point not yet.
In an embodiment of the present invention, described wait login duration value T is not less than a default wait login duration lower limit T
min.In the process be connected with the access point that cannot directly automatically log in, need user to have the sufficient time manually to initiate logging request, wait for and log in duration lower limit T
minensure that this time requirement.Wherein, login duration lower limit T is waited for
minindependently can be set by the service condition of user or use habit.
In an embodiment of the present invention, described wait logs in duration higher limit T
maxbe not more than a wait and log in duration upper limit threshold.
Wait for that logging in duration higher limit is not arbitrarily set, and needs to adjust according to actual conditions.Such as, front in terminal " passive disconnection ", user is the Internet service can possessing certain buffer memory at viewing Online Video etc., so generally, waits for and logs in duration higher limit T
maxthe duration value T ' being not more than cache contents and playing need be set, wait for that logging in duration upper limit threshold is exactly the duration value T ' that cache contents plays.A situation fixing limit value can be obtained like this, just need to obtain this value in advance and log in duration upper limit threshold as wait, limit and wait for and log in duration higher limit T
maxvalue; And for knowing the situation of duration value T ' that cache contents plays, can call that terminal inner pre-sets one waits for and logs in duration acquiescence higher limit T
max0.So, wait for that logging in duration value T need meet:
T
min≤ T≤T
max≤ T ' or T
min≤ T≤T
max≤ T
max0.
Wherein, step 12 comprises:
Step 121 ', when described terminal is attempted after described second access point of access reaches pre-determined number threshold value in predetermined time threshold value, described terminal still unsuccessful access described second access point time, disconnect the attachment state of described terminal and described second access point.
Except logging in except the Rule of judgment of duration value as active disconnection, in step 121 by waiting for ' in, also whether can reach pre-determined number threshold value to judge whether initiatively disconnection according to the number of times attempting access access point.Certainly, two kinds of above-mentioned Rule of judgment are only two kinds of preferred embodiments, and other Rule of judgment that can be suitable for also are fine, and do not enumerate at this.
In the method for the embodiment of the present invention, step 13 comprises:
Step 131, from all access points, select highest-ranking 3rd access point of current priority, complete the connection of described terminal and access point according to access conditions, wherein, described all access points comprise whole access points that described terminal current search arrives.
Wherein, access conditions comprises:
The signal strength signal intensity of the access point that terminal receives is not less than the bottom threshold (this bottom threshold is generally-80dBm ~-75dBm in engineering) of terminal access; Further, terminal successfully can be intercepted and demodulate the beacon frame that the access point cycle issues.
Because the access point that priority-level is the highest wishes first to connect most, so according to step 131, highest-ranking 3rd access point of current priority can be selected from all access points, complete the connection of terminal and access point according to access conditions, make user can proceed normal data service.
Certainly, terminal current search to whole access points in be possible comprise the access point once disconnected, therefore, the 3rd access point in step 131 may be the first access point once disconnected, and also may be access point medium priority other access points highest-ranking that Current Scan arrives.If the signal condition of the first access point meets access conditions again and does not have new access point to add, 3rd access point is exactly the first access point once disconnected, thus make user can continue use before access access point carry out normal data service.
Certainly, in the access point that may again obtain, the access point of highest priority level is not one meet access conditions surely, therefore, on the terminal the stating embodiment on the invention basis of method that intelligence switches between access points, the step completing the connection of described terminal and access point in step 131 according to access conditions comprises:
Step 1311, if described 3rd access point meets access conditions, then described terminal is by described 3rd access point of trial access;
Step 1312, if described 3rd access point does not meet access conditions, then described terminal will attempt the 4th access point lower than the priority-level of described 3rd access point in the described all access points of access.
Like this, if the 3rd access point meets access conditions, so again select the 3rd access point and adhere to, directly automatically log in, make user can proceed normal data service; If now the 3rd access point does not still meet access conditions, so continue to attempt access four access point lower than the priority-level of the 3rd access point.
When attempting access the 4th access point, adhere to successfully, terminal may Successful login, but can not the 4th access point of repeated attempt connection without end, and therefore, state on the invention on the basis of embodiment, described method also comprises:
Step 14, after when described terminal, in predetermined time threshold value, described in logon attempt, the 4th access point reaches pre-determined number threshold value, described terminal still unsuccessful login described 4th access point time, described terminal attempts the access point of access priority rank lower than described 4th access point priority-level, until successfully access by automatically starting.
Attempt connecting after login the 4th access point reaches pre-determined number threshold value in predetermined time threshold value, just can give tacit consent to the possibility not having and successfully connect the 4th access point, do not need to reattempt access the 4th access point, according to above-mentioned steps, the access point of access priority rank lower than the 4th access point priority-level is attempted, until successfully access by automatically starting.
When before terminal trial access, N-1 access point is all failed, terminal attempts access N access point by automatically starting.
In an embodiment of the present invention, be understandable that, although term first, second, third, fourth can be used for describing various access point at this, but these access points should not be limited to these terms, such as access point can be defined as the first access point in one scenario, in another scene, also can be defined as the 3rd access point.
Acquiescence below in conjunction with operator's erection trusts access point: CMCC-AUTO, CMCC and CMCC-EDU illustrate the terminal intelligent method switched between access points of the embodiment of the present invention:
The priority-level of default setting CMCC-AUTO higher than the priority-level of CMCC, CMCC higher than CMCC-EDU.
Certain terminal resides in certain CMCC-AUTO focus, and normally carry out data service, but because burst reason causes current signal(l)ing condition cannot ensure to communicate with minimum speed limit between this terminal with this CMCC-AUTO access point again, thus this terminal there occurs the phenomenon of " passive disconnection ".Now, this terminal meets in all access points of access conditions at all the other and have selected priority time high CMCC access point and carry out trials and access, and is successfully attached to this CMCC access point.
But because CMCC access point needs user manually to initiate to log in, if user does not initiate logging request all the time, so this terminal in the attachment of this CMCC access point and non-login time reach and wait for and log in duration upper limit T
maxtime (T
max=60 seconds), terminal " initiatively will disconnect " attachment state with this CMCC access point, reenter the state of not yet adhering to any access point of Attach, if now the signal(l)ing condition of CMCC-AUTO access point meets access conditions again, so this terminal will attempt carrying out adhering to, automatically logging in Autologging at CMCC-AUTO access point again.Thus make user can continue to use access point to carry out normal data service.
Wherein, using video traffic or can know that buffer memory plays the situation of duration value if there is " passive disconnection " front user, the duration value T ' that can play according to cache contents time terminal " passive disconnection ", T
max≤ T ' obtains T
max=60 seconds; If cannot know that buffer memory plays the situation of duration value, the wait can preset according to terminal logs in duration acquiescence higher limit T
max0, T
max≤ T
max0obtain T
max=60 seconds.And, in order to ensure that user has the sufficient time manually to initiate logging request, waiting for that login duration value T also will meet to be not less than and waiting for login duration lower limit T
min, T
min≤ T≤60 second.
Certainly, if now the signal(l)ing condition of CMCC-AUTO access point does not still meet access conditions, so this terminal will attempt CMCC access point again.When in certain time interval T
0logon attempt CMCC access point reaches N
0after secondary, terminal is unsuccessful login still, and so terminal attempts next priority CMCC-EDU access point of access by automatically starting.
Wherein, namely CMCC-AUTO access point is the first access point in the embodiment of the present invention is also the 3rd access point, and namely CMCC access point is the second access point is also the 4th access point.
Consider various factors, user and operation commercial city wish preferred limit priority access point CMCC-AUTO, according to the method for the embodiment of the present invention, causing owing to not logging in after trial access CMCC access point cannot successful connection, if now the signal(l)ing condition of CMCC-AUTO access point meets access conditions again, so this terminal will attempt carrying out adhering to, automatically logging in Autologging at CMCC-AUTO access point again, complete and return higher priority access point from lower priority access point, meet the needs of user and operator.Meanwhile, if user adheres to CMCC access point but do not log in, focus IP can be taken always, make the real user needed not have IP to use, rear active cannot be logged in and disconnect, also avoid the waste of resource well.
