Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Incorporated by reference to referring to Fig. 1, the embodiment of the present invention provides a kind of method of reserved storage space, shift to an earlier date downloading service content to reserved storage space according to the weight of business tine and priority thereof, reduce the waiting time that content service switches, strengthen the lifting of the preliminary treatment ability of terminal, the friendly that further strengthens user interactions, reaches lower delay requirement, meets the requirement that user uses.The method of the embodiment of the present invention comprises:
Step 102, determines the business tine of downloading in advance according to business tine weight.
In embodiments of the present invention, operational authority retraces states user's use habit, can determine business tine weight according to user's use habit.Weighted value and business tine access times, time span etc. are associated.The method of determining business weight is specifically as follows: use the duration of business tine and access times to determine described business tine weight according to the user in the unit interval.
Take IPTV demand (telecommunication) service as example, its weighted value account form is as follows: the user in observation unit's time watches program duration and access times, and access times are higher, weighted value is larger, program duration is larger, illustrates that user watches that this program wish is larger, switches this channel possibility also just larger.If the weight of business I is W
i, program viewing duration is τ
i, play-on-demand program number of times is A
i, within the unit interval, its weighted value is w so
i=Σ τ
ia
i.Unit interval can be week, month, or season be unit.Certainly, the time is shorter, and precision is higher, and this is because user's custom has the continuity in the short time.If time period of supervision is long, it is accurate not that data content also can become.Watch custom because weighted value characterizes user, therefore still need to be unified for integer range, for subsequent calculations storage size.
Suppose using week as unit as the weight update cycle.Have three business, business 1 weighted value is 13.2, the weighted value 14 of business 2, the weighted value 8.3 of business 3.Because proportion range is defined as [1, M] integer range, after business 1 mapping, its weighted value is M so, and the weighted value of business 2 is M-1, the weighted value of business 3 be M-2. wherein M be more than or equal to 3.
Business tine weighted value is higher, illustrate that the time using is longer in user's use habit, this content of user preference is also described, in next handoff procedure, weighted value is higher so, the possibility of switching is also larger, and the possibility of the reserved needed space size of this content of memory space also should be larger so.
Use in business procedure user, the business tine that user can select is a lot, therefore, can not be used for downloading service content in advance by the reserved certain memory space of each content, therefore, conventionally need to pre-determine the business tine that need to download in advance, follow-up reserved memory space is mainly to determine that for these the business tine that need to download is in advance reserved.Determining in the process which business tine need to be downloaded in advance, can determine with reference to the weight of business tine, determine by the use habit of business tine according to user.Such as, in the time using IPTV request program, according to user habit, user's general operation is all advanced, retreat, or rollback, or select the channel program of oneself often liking, therefore, above-mentioned program can be defined as to the business tine that need to download in advance.Determining that when business tine, the scope of business tine is too much unsuitable, also unsuitable very few, too much easily cause connecting and consume excessively, waste memory space, very fewly can not reflect that again user, in the time of service switchover content, likes successional impression in time.Generally be no more than 5 business tines of downloading in advance.
Step 104 is the described business tine reserved storage space of downloading in advance.
In embodiments of the present invention, in order to guarantee the business continuance of user in the process of service switchover content, can be the size that the business tine downloaded is in advance determined reserved storage space according to business tine weight, total storage size, the in advance number of downloading service content and service rate.
Take IPTV program request as example, different types of service is determining that the service and the charge grade that provide are different.For example, the image quality of high definition order video and ordinary video is just had any different, and reason is that the bandwidth of HD video is larger, and the resource taking is more, and speed is also higher.Meanwhile, its delay requirement of different types of service is also different, and for stream business, delay requirement is higher, and for general ftp business, delay sensitive requires also not high.According to the grade of business customizing and type, reserved certain cushion space size respectively.Concrete reserved great memory space, according to total cache size, business number, the composite factors such as speed are considered.For type of service I, the pre-spatial cache size of its business is as formula
Shown in, wherein M represents memory space total capacity, W
iexpression business is switched weight, V
iexpression business i switches weight, M
isign business I downloads spatial cache amount of capacity: for example total spatial cache size is M, and the to be switched number of programs of recommendation is N, and N is 3, and program speed is respectively V1, V2, V3.Program weight is respectively W1, W2, W3.So, the pre-download space size of program 1 is:
Other business program request 2 and 3 reserved storage space sizes by that analogy.
Step 106, is downloaded to reserved memory space by the content of business in advance according to business tine priority weights level order from high to low.
In embodiments of the present invention, determine in advance after the business tine downloaded and reserved storage size thereof, in the use procedure of current business content, can start the download flow process of the business tine of downloading in advance, downloading priority downloads from big to small successively according to business weight weights, this is because the possibility that higher its user of business of weights uses is also just larger, therefore, needs preferentially to guarantee that the too high business of weighted value has enough spatial caches for its service.
Take IPTV as example, suppose that proportion range is defined as [1, M], the business that wherein weight is M is the reserved pre-download flow space needing preferentially, by that analogy, if spatial cache is not finished, then reserves the required pre-download flow requisite space of business that weight is M-1.Because IPTV number of programs is too much, can not each business carry out pre-download, can cause like this storing excessive, high cost, also unrealistic.Therefore,, according to the sequence of priority size, priority is that weighted value is larger, preferentially downloads.
Alternatively, in embodiments of the present invention, consider that user habit may exist difference within the different time periods, therefore, can regular update business tine weight or reserved storage space, such as, upgrade its business weighted value according to the recent use habit of user, and further determine the business tine that need to download is in advance upgraded, meanwhile, also can correspondingly be automatically updated into its reserved memory space according to the downloading contents in advance after upgrading.
In order to realize better the more record of fresh content, can safeguard corresponding list, such as, take IPTV as example, can safeguard a business and channel relation table, in table, field is as follows: channel ID, type of service, service rate, lowest tolerated time delay, business is switched the association attributeses such as weight, according to the value of the above-mentioned field of cycle regular hour regular update.Wherein business switching weight is analogous to channel switching weight, and this business is by the possibility of user's program request in the time using IPTV business, and weighted value is larger, and the possibility that is switched to this channel is also larger.
Although above-described embodiment is mainly set forth as an example of IPTV example, but, alternatively, in embodiments of the present invention, described business comprises VOD service, interactive entertainment business, web page browsing, video communication business or instant messaging business, and business tine comprises respectively business channels, type of play, web page address, video communication object or instant messaging type of service.For other business, such as, web page browsing business, can determine according to user's use habit the business weight of each web page address, such as, the often web page address of access, the web page address of recent visit etc. can be confirmed as the business tine that need to download in advance, and be its reserved storage space, in the time of user's open any browser, can in advance the content of corresponding web page address be downloaded to reserved memory space in advance, or, according to the use habit of the sequencing of user's accessed web page address, determine the maximally related web page address of current accessed web page address, and determine that maximally related web page address is under current accessed webpage, to need the business tine downloaded in advance, and in the time browsing current web page, shift to an earlier date downloading service content to reserved storage space, like this, in the time that user need to be switched current web page, can be switched to fast corresponding web page, meet the successional impression of user.
