Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Fig. 1 shows the flow chart of the data buffering method of one embodiment of the invention, is applied to mobile terminal, comprising:
Step 110: in the case where playing streaming multimedia data, obtaining mobile terminal in real time in next preset duration
Into the probability of target area.
Preferably, the present embodiment application scenarios are that mobile terminal is in moving condition, because mobile terminal is in moving condition,
Location information can change, and the corresponding wireless network signal quality of different location informations is different, therefore more playing crossfire
In the case where media data, plays streaming multimedia data and be affected by wireless network signal mass change, thus this reality
The wireless network signal quality for applying the avoidable variation of example causes Caton etc. to influence on streaming multimedia data are played.
Mobile terminal is in moving condition, for example, user rides in the viewing more matchmakers of crossfire such as subway, public transport, train, high-speed rail
The case where volume data.
Preferably, streaming multimedia such as video, audio etc..
Further, in this embodiment data buffering method be more suitable for user for a long time viewing streaming multimedia data
The case where.
Mobile terminal enters the probability of target area in next preset duration, it may include a variety of situations.
Illustratively, often on and off duty at a fixed time based on user, then mobile terminal can be according to the on and off duty of user
Rule, within the specific period, the region that prediction mobile terminal need to pass through, so as to obtain the general of target area therein
Rate.
Alternatively, the region of surrounding is detected according to the location information of mobile terminal, to estimate the area that user may go to
Domain, and then the probability of target area therein can be obtained.
It preferably, can also be according to default confidence breath, historical data information, the operator/hand in network in mobile terminal
Big data server info etc. in machine manufacturer/application software server information, network obtains mobile terminal next pre- in real time
If entering the probability size of target area in duration.
In the epoch of communication technology rapid development, almost each region is covered with wireless network signal, and different is wireless
Network communicating system technology corresponds to different wireless network signal types, and wireless network signal type includes Wireless Fidelity
(Wireless-Fidelity, abbreviation WiFi), Generation Mobile Telecommunication System technology (The 2rd Generation
Telecommunication, abbreviation 2G), 3rd generation mobile communication technology (The 3rd Generation
Telecommunication, abbreviation 3G), the 4th 3 g mobile communication technology (The 4rd Generation
Telecommunication, abbreviation 4G), the 5th third-generation mobile communication technology (The 5rd Generation
Telecommunication, abbreviation 5G) etc..Because being covered on each region wireless network signal type difference, same wireless network
Intensity, the behaviour in service of signal type are also different, cause the wireless network signal quality of each region different, the nothing in some regions
Line network signal quality is preferable, is able to satisfy the default broadcasting fluency of streaming multimedia data, plays streaming multimedia data not
Caton, and the wireless network signal in some regions is second-rate, is unable to satisfy the default broadcasting fluency of streaming multimedia data,
Play streaming multimedia data Caton.
Target area in the step refers to the region for being unable to satisfy the default broadcasting fluency of streaming multimedia data.
It should be noted that the default fluency that plays at least can reach the effect of not Caton.
Step 120: being greater than the feelings of first threshold into the probability of target area in next preset duration in mobile terminal
Under condition, before mobile terminal enters target area, the corresponding streaming multimedia data played in target area are downloaded in advance
In buffer area.
It in embodiments of the present invention, need to be by means of wireless network signal download online, nothing because playing streaming multimedia data
Line network signal quality directly influences the fluency of streaming multimedia data playback, and is covered on the wireless network of different zones
Signal quality is different.Therefore, in the case where playing streaming multimedia data, mobile terminal is obtained in real time next default
Enter the probability of target area in duration, goal region refers to the default broadcasting stream for being unable to satisfy streaming multimedia data
The region freely spent, in the case where probability of the mobile terminal in next preset duration into target area is greater than first threshold,
There is Caton in order to avoid mobile terminal plays streaming multimedia data in target area, enters target area in mobile terminal
Before, the corresponding streaming multimedia data played in target area are downloaded in buffer area in advance, in this way, mobile terminal is entering
Behind target area, streaming multimedia data have been buffered to buffer area, and the streaming multimedia data of broadcasting are buffered data, not by nothing
Line network signal quality influences, so that it is guaranteed that mobile terminal plays the fluency of streaming multimedia data in target area, avoids
Caton is played, user's viewing experience is improved.
On the basis of embodiment shown in Fig. 1, Fig. 2 shows the streams of the data buffering method of another embodiment of the present invention
Cheng Tu, buffer area is preset with initial play duration buffering threshold values, before step 120, further includes:
Step 130: in the case where playing streaming multimedia data, by the streaming multimedia of next initial play duration
Data are downloaded in advance in the buffer area for being set as initial play duration buffering threshold values.
In the case where playing streaming multimedia data, cause in order to avoid the wireless network signal because of subsequent period is poor
The streaming multimedia data that subsequent period plays can be downloaded in buffer area, thus even if the nothing of subsequent period by Caton in advance
Gauze network dtr signal, user can also enjoy smooth viewing experience in subsequent period.
In most of usage scenario, the playing duration buffering threshold values of buffer area is that initial play duration buffers threshold values.
Preferably, initial play duration buffering threshold values may be configured as 10s, i.e., in streaming multimedia data playback, in advance
Download the streaming multimedia data of 10s.
Accordingly, step 120 includes:
Step 1201: obtaining the target playing duration of the corresponding streaming multimedia data played in target area.
On the basis of step 130 realization of functions, if mobile terminal is in next preset duration into target area
Probability is greater than first threshold, then before mobile terminal enters target area, obtains mobile terminal by needed for target area
The target playing duration of time, i.e. target area broadcasting streaming multimedia data.
Step 1202: in the case where target playing duration is greater than initial play duration buffering threshold values, being played according to target
Initial play duration buffering threshold values is improved to interim playing duration and buffers threshold values by duration.
Step 1203: the streaming multimedia data that target area corresponds to target playing duration being downloaded to rise in advance and are faced
When playing duration buffering threshold values buffer area in.
If target playing duration, which is greater than initial play duration, buffers threshold values, illustrate that mobile terminal is entering target area
Afterwards, the inadequate user of streaming multimedia data in buffer area watches in entire target area, therefore according to this situation, will initially broadcast
Duration buffering threshold values is put to improve to interim playing duration buffering threshold values.
It should be noted that interim playing duration buffering threshold values is more than or equal to target playing duration.
Preferably, interim playing duration buffering threshold values person is equal to target playing duration.
For example, initial play duration buffering threshold values is 10s, target playing duration is 20s, then buffers interim playing duration
Threshold value setting is 20s, so that mobile terminal is before entering target area, by the streaming multimedia data buffering of 20s to slow
It rushes in area, and then can ensure that mobile terminal plays the fluency of streaming multimedia data in target area.
Preferably, can also according to mobile terminal from current region to target area during, the region passed through
Interim playing duration buffering threshold values is set to be large in target playing duration by situations such as wireless network signal, elapsed time,
To ensure before mobile terminal reaches target area, the data that target area plays all are downloaded.
It is contemplated that in order to avoid mobile terminal when target area stopped long-time broadcast interface Caton, can will be first
Beginning playing duration buffering threshold values is arranged long, to save interim the step of improving playing duration buffering threshold values.For example, one
The playing duration of video is or so 1 hour, so that 1h is set by initial play duration buffering threshold values, in this case, as long as
Video plays at the beginning, so that it may and entire video download to local side etc. is to be played, even if subsequent by target area, also not
It will affect user's experience.But in general, terminal limited memory, and terminal memory is the resource of multiple Application sharings,
Therefore the playing duration buffering threshold values for the buffer area that general streaming multimedia player is taken accordingly is limited, thus cannot achieve by
Initial play duration buffering threshold values is arranged too long；In addition, mobile terminal can not predict the idea of user, user not necessarily can be
Entire video is finished watching, therefore initial play duration buffering threshold values is arranged too long, and unnecessary flow wave can be also brought to user
Take.
In the present embodiment, temporarily the playing duration of adjustment buffer area buffers threshold values, and interim raising according to the actual situation
Playing duration buffering threshold values according to actual conditions it is changeable, not only ensure user target area watch streaming multimedia number
According to when, there is no Caton phenomenon, will not also occupy long-time occupied terminal memory, while not will cause unnecessary flow wave
Take.
Referring to Fig. 3, when buffer area is set as initial play duration buffering threshold values, only in streaming multimedia buffer area buffer number
According to；When buffer area is set as interim playing duration buffering threshold values, streaming multimedia buffer area and streaming multimedia extra buffer
Common buffered data.Wherein, streaming multimedia extra buffer size determine extra buffer data volume number.
In the present embodiment, the playing duration buffering threshold values of buffer area is for embodying cacheable streaming multimedia data
Longest playing duration.In more embodiments, buffer area can also preset other types of buffering threshold values, can buffer for embodying
Streaming multimedia data maximum value.For example, the maximum value of the streaming multimedia data of buffering is several MB etc..
On the basis of embodiment shown in Fig. 2, Fig. 4 shows the stream of the data buffering method of another embodiment of the present invention
Cheng Tu, step 1202 include:
Step 12021: obtaining the first location information of mobile terminal and the second location information of target area.
Preferably, the second location information of target area is obtained in advance and obtains the first positioning of mobile terminal in real time
Information.
Wherein, the second location information of target area can be understood as a fixed location information, and mobile terminal
The first location information can be understood as the location information of real-time change.
Step 12022: in the case where the first location information and the second location information meet predeterminated position relationship, according to mesh
Playing duration is marked, initial play duration buffering threshold values is improved to interim playing duration and buffers threshold values.
If too early improve initial play duration buffering threshold values to interim playing duration buffers threshold values, terminal stream will result in
The waste of amount, memory；If improving initial play duration buffering threshold values to interim playing duration buffer threshold values too late, will result in
Buffering is insufficient.
In this step, initial play duration buffering threshold values is specifically set to improve to interim playing duration buffering threshold values
The specific moment meets the corresponding moment of predeterminated position relationship in the first location information with the second location information.
First location information and the second location information meet predeterminated position relationship, comprising: mobile terminal is believed from the first positioning
Breath variation is the second location information.That is, when mobile terminal is moved to target area from current location, it at least can be just by target
Playing duration is downloaded in buffer area.
Wherein, predeterminated position relationship includes a variety of situations, the wireless network before predeterminated position relationship and arrival target area
At a distance from signal quality, the corresponding target playing duration in target area, the first location information are spaced between the second location information
Etc. relevant.
Further, in the case where the first location information and the second location information meet predeterminated position relationship, can pass through
Intelligent early-warning module is set, intelligent early-warning module is used to notify streaming multimedia player adjustment playing duration buffering threshold values, with
The size of data can be accommodated by changing buffer area.
For example, the working route of user is cell 1, cell 2, cell 3, cell 4, target area, cell 5, user enters
After cell 4, can predict mobile terminal enter target area probability it is larger, thus by initial play duration buffering threshold values mention
Up to interim playing duration buffers threshold values, but is likely to that streaming multimedia player is caused not have enough time buffering target to broadcast
Duration is put, therefore can be improved ahead of time.After entering cell 3 such as user, while cell 4 is detected around, then predict movement
The probability that terminal enters target area is larger, buffers to then improve initial play duration buffering threshold values to interim playing duration
Threshold values, such streaming multimedia player just have enough time to buffer target playing duration.
And in this example, it is believed that, after user enters cell 3, the first location information of mobile terminal and target area
The second location information meet predeterminated position relationship.
And in the concrete realization, the mobile route of mobile terminal has uncertainty, and mobile terminal is in next preset duration
Interior probability nor a hundred percent into target area, therefore can not accurate definition predeterminated position relationship.
Therefore, in order to embody predeterminated position relationship, the present embodiment also proposed this concept of confidence threshold values, confidence valve
Value embodiment whether have enough be held in into target area before complete data buffering.It is meant that expressed by confidence threshold values: letter
Heart threshold values is bigger, that is, have enough be held in into target area before complete data buffering, can improve later playing duration buffering
Threshold values；Confidence threshold values is smaller, i.e., no enough be held in into target area before complete data buffering, broadcasting can be improved earlier
Duration buffers threshold values.
Wherein, confidence threshold values can be customized by users setting.Different confidence threshold values, corresponding predeterminated position relationship is not yet
Together.
For example, confidence threshold values is larger, playing duration buffering threshold values can be improved later, preferable mobile terminal end is when next default
When probability in long into target area is larger, improves playing duration and buffer threshold values.Referring to above-mentioned example, the movement of user's working
Route is successively to pass through cell 1, cell 2, cell 3, cell 4, target area, cell 5, fixed according to mobile terminal real-time first
Position information, learns mobile terminal successively and have passed through cell 1, cell 2, cell 3, cell 4, and do not detect alternative mesh
The candidate cell in region is marked, at this moment, probability of the mobile terminal in next preset duration into target area is larger, improves and plays
Duration buffers threshold values.As it can be seen that the second location information of the first location information and target area after mobile terminal enters cell 4
Meet predeterminated position relationship.Confidence threshold values is larger, avoids buffered data in advance, so that flow be avoided to waste.
For another example, confidence threshold values is smaller, can improve playing duration buffering threshold values earlier.It goes to work referring to above-mentioned example, user
Mobile route is successively to pass through cell 1, cell 2, cell 3, cell 4, target area, cell 5, according to mobile terminal real-time the
One location information, learns mobile terminal successively and have passed through cell 1, cell 2, at this moment, mobile terminal in next preset duration into
Entering target area has certain probability, then improves playing duration buffering threshold values.As it can be seen that after mobile terminal enters cell 2
First location information and the second location information of target area meet predeterminated position relationship.Confidence threshold values is smaller, and avoiding does not have
The case where enough time buffered data, occurs.
It should be noted that even if propose the concept of confidence threshold values, but predeterminated position relationship still to combine it is other auxiliary
Supplementary information, to avoid not having the case where enough time buffered data.
Preferably, the probability that mobile terminal enters target area in next preset duration is obtained, people from cloud can be used
Work intelligence or terminal artificial intelligence carry out algorithm modeling, to speculate the probability into target area, thus the accuracy of probability.
Except the introducing of above-mentioned confidence threshold concept, predeterminated position relationship can also be more situations.
For example, with reference to cell distribution schematic diagram shown in fig. 5, the region that user is currently located is in 1~cell of cell 11
Any region, the region X (Area) is target area, because X Area and 1~cell of cell 11 are closer, therefore mobile terminal
Probability in next preset duration into target area is larger, so as to need to improve playing duration buffering threshold values.Specifically
Ground, by these cells be divided into the adjacent cell of XArea (cell 7, cell 9, cell 10, cell 11), i.e., first layer is adjacent
Cell and the cell being separated by with X Area, i.e. second layer neighboring community, the cell localization information according to locating for user, and
Locating cell type improves playing duration and buffers threshold values.
As it can be seen that predeterminated position relationship depends on the neighboring extent with target area in said circumstances, thus referring to mobile whole
Neighboring extent between first location information and the second location information at end improves playing duration and buffers threshold values.
Wherein, the neighboring extent of each cell and target area, can be by mobile terminal self learning records, can also be by net
Network big data server assists learning records.
Accordingly, step 1203 includes:
Step 12031: the streaming multimedia data of next interim playing duration being downloaded to rise in advance and are temporarily broadcast
In the buffer area for putting duration buffering threshold values.
When buffer area is set as interim playing duration buffering threshold values, when playing streaming multimedia data, according to current
Playing duration buffer threshold values, the streaming multimedia data of next interim playing duration are buffered, thus when mobile terminal enters
Before target area, to buffer the streaming multimedia data of interim playing duration, the streaming multimedia data of interim playing duration
Including at least the streaming multimedia data of target playing duration, and then ensure that user watches buffered data in target area.
In the present embodiment, according to the second of the first location information of the mobile terminal obtained in real time and target area
Location information, and meet with the second location information default referring to the predeterminated position relationship in actual conditions when the first location information
When positional relationship, initial play duration buffering threshold values is improved to interim playing duration buffer threshold values in time, so that player has
Chance takes urgent of short duration increasing buffer area data volume in advance, and downloads more data in advance in buffer area, when it is mobile eventually
When holding really by target area, can still user be allowed not meet with Caton, so as to improve user experience.
On the basis of embodiment shown in Fig. 2, Fig. 6 shows the stream of the data buffering method of another embodiment of the present invention
Cheng Tu, after step 1203, further includes:
Step 130: being less than or equal to first in probability of the mobile terminal in next preset duration into target area
In the case where threshold value, it is reduced to initial play duration to buffer threshold values interim playing duration buffering threshold values.
In the present embodiment, in order to avoid the waste of unnecessary flow, enter in next preset duration in mobile terminal
In the case that the probability of target area is less than or equal to first threshold, interim playing duration buffering threshold values is reduced to initially in time
Playing duration buffers threshold values.
On the basis of embodiment shown in Fig. 1, Fig. 7 shows the stream of the data buffering method of another embodiment of the present invention
Cheng Tu, step 110 include:
Step 1101: the historical data gone on a journey according to user obtains the mobile terminal in next preset duration in real time
Into the probability of target area.
The life range of user is fixed, therefore there are the governed moulds of mark for wireless network resource used in mobile terminal
Formula.
For example, user is on every Mondays to 7 o'clock of the morning of Friday~this period at 10 o'clock, it all can be from family in by the subway
To office, in this section of distance, the cell that the mobile terminal of the user would generally pass through is successively: cell 1 (in family), cell 2,
Cell 3, cell 4, cell X and cell 5 (office), since the period that user fixes daily can all pass through these cells,
Mobile terminal can store the trip historical data of cell 1, cell 2, cell 3, cell 4, cell X and cell 5 (office)
Get up.
Later, mobile terminal can obtain mobile terminal in next preset duration into each cell within this period
Probability, and the practical transfer sequence of real-time contrast user, to verify whether the historical data feature for meeting storage, if meeting storage
It is larger then to can be predicted probability of the mobile terminal in next preset duration into target area for the historical data feature deposited；Such as
Fruit does not meet the historical data feature of storage, then the prediction route of adjustment adjustment in time.
Alternatively, step 1102: according to the moving range of user preset, obtaining mobile terminal in real time in next preset duration
Into the probability of target area.
For example, user can be pre-seted by user interface (User Interface, abbreviation UI), user is on UI
Face sets a geographic life range range, the i.e. moving range of user preset, so that mobile terminal can be according to user preset
Moving range, obtain mobile terminal in next preset duration enter target area probability.
In this step, if in the moving range of user preset, there is at least one target area, then according to terminal positioning
Information and the spaced relationship of target area etc. set predeterminated position relationship, thus in time by initial play duration trimmer valve in time
Value improves to interim playing duration and buffers threshold values.
In the present embodiment, when user, which is in, watches prolonged streaming multimedia under moving condition, because of the more matchmakers of crossfire
The broadcasting of volume data is influenced by the wireless network signal quality moved, in order to avoid playing streaming multimedia number under target area
According to leading to Caton, therefore obtain the probability that mobile terminal enters target area in next preset duration.It wherein, if can
Accurate moving state is got from navigation software etc., then can accurately predict mobile terminal in next preset duration whether into
Enter target area；Alternatively, can be accustomed to according to the trip of user, the biggish mobile route of probability, and real time correction are obtained, with real-time
Obtain the probability that mobile terminal enters target area in next preset duration；Alternatively, can according to the customized setting of user,
The a plurality of biggish mobile route of probability is obtained in the moving range of user preset, because the mobile route of acquisition is more, so as to
The target area of entrance is also more, thus between the changing factor and user and each target area in comprehensive actual conditions
Spaced relationship, in real time obtain mobile terminal in next preset duration enter target area probability.As it can be seen that being based on this implementation
A variety of acquisition mobile terminals in example enter the probability of target area in next preset duration, with the standard of the probability ensured
There is Caton in target area viewing streaming multimedia to not only can avoid user, but also can reduce because erroneous judgement enters target in true property
Region, caused by flow waste.
On the basis of embodiment shown in Fig. 1, Fig. 8 shows the stream of the data buffering method of another embodiment of the present invention
Cheng Tu, before step 110, further includes:
Step 140: obtaining the corresponding wireless network signal strength of third location information of mobile terminal.
Step 150: in the case where the corresponding wireless network signal strength of third location information is less than second threshold, by the
The corresponding region of three location informations is determined as target area.
The present embodiment can obtain the wireless network signal strength in the region of mobile terminal process, if wireless network signal strength
Less than second threshold, that is, it is unable to satisfy the default broadcasting fluency of streaming multimedia data, is then stored in this as target area
Ground.
For example, user is in first time by cell 1 (in family), cell 2, cell 3, cell 4, cell X and the (office of cell 5
Room) route when, while storing route, can also store the corresponding wireless network signal strength of these cells.To known to
The wireless network signal strength being covered within the scope of cell X is unable to satisfy the default broadcasting fluency of streaming multimedia data, then
Cell X is determined as the target area in the route.
In addition, the mobile route stored within the same period may also can change, for example, user is from family to doing
During public room is mobile, possible today, 2 signal of cell was preferable when by some region, therefore successively passed through 1 (family of cell
In), cell 2, cell 3, cell 4, cell X, cell 5 (office), and tomorrow when by some region, may be cell
6 signals are better than 2 signal of cell, therefore successively by cell 1 (in family), cell 6, cell 3, cell 4, cell the X, (office of cell 5
Room).Mobile terminal for these features can define certain memory space to store multiple features, when memory space without
When method stores new feature, it can choose and do not store emerging feature, or from the feature of script storage, delete a part,
New feature can be stored.To constantly update, the personal user's data stored are enriched, obtain the mobile terminal under to improve
Enter the accuracy of the probability of target area in one preset duration.
Further, the target area being locally stored can be uploaded to common end, such as server by user, be made for more users
With.
For example, can be according to the scope of activities of user preset, from operator, cell phone manufacturer, application software vendor server
The target area in the scope of activities is downloaded in equal common ends, so that mobile terminal can compare cell switching kenel, prediction is gone to connect
Get off to enter the probability of target area.
Preferably, it is regarded as public from the data of the downloadings such as operator, cell phone manufacturer, application software vendor server
User data.Operator/cell phone manufacturer/application software manufacturer can penetrate OTA or USB interface, carry out default and set.User or
Operator/cell phone manufacturer/application software manufacturer can also carry out default and set through the tool software on mobile terminal.
Wherein, the setting of wireless base station/cell is constant, the wireless network signal of institute overlay area with regard to more stable, but
When change is arranged (such as some cell temporary repair), at this moment mobile terminal can also be uploaded newfound target area
To common ends such as operator/cell phone manufacturer/application software vendor servers.To which more users can obtain target from common end
