Incorporated by reference to referring to Fig. 1, the embodiment of the present invention provides a kind of method of reserved storage space, according to the power of business tine
Weight and its priority shift to an earlier date downloading service content to reserved storage space, reduce the waiting time of content service switching, enhancing
The promotion of the pretreatment potentiality of terminal further enhances the friendly of user's interaction, reaches relatively low delay requirement, meet user
The requirement used.The method of the embodiment of the present invention includes：
Step 102, the business tine downloaded in advance is determined according to business tine weight.
In embodiments of the present invention, operational authority, which retraces, states user's use habit, can be determined according to user's use habit
Business tine weight.Weighted value and business tine access times, time span etc. are associated.The method for determining business weight is specific
Can be：The business tine weight is determined using the duration and access times of business tine according to the user in the unit interval.
By taking IPTV demand (telecommunication) services as an example, weighted value calculation is as follows：User in observation unit's time watches program
Duration and access times, access times are higher, and weighted value is bigger, and program duration is bigger, illustrate that user watches this program wish more
Greatly, it is also bigger to switch this channel possibility.If the weight of business I is Wi, a length of τ during program viewingi, play-on-demand program number is
Ai, then its weighted value is w in the range of the unit intervali=Σ τiAi.It week, the moon or season is single that unit interval, which can be,
Position.Certainly, the time is shorter, and precision is higher, this is because the custom of user is with the continuity in the short time.If the time is investigated
Excessive cycle, data content can also become inaccurate.Due to weighted value, characterization user watches custom, and there is still a need for united
One is integer range, for subsequently calculating storage size.
It is assumed that using as unit of week as the weight update cycle.There are three business, and 1 weighted value of business is 13.2, the power of business 2
Weight values 14, the weighted value 8.3 of business 3.Since proportion range is defined as [1, M] integer range, then after business 1 maps, power
Weight values are M, and the weighted value of business 2 is M-1, and the weighted value of business 3 is more than or equal to 3. for M-2. wherein M
Business tine weighted value is higher, illustrates that the time used in user's use habit is longer, also illustrates user preference
This content, then weighted value is higher in next handoff procedure, and the possibility of switching is also bigger, then memory space is reserved in this
The possibility for holding required space size also should be bigger.
In user is using business procedure, there are many business tine that user can select, therefore, it is not possible to each content
Reserved certain memory space is for downloading service content in advance, it is thus typically necessary to which predefining needs the industry downloaded in advance
Business content, the memory space of subsequent reservation mainly for these determine that the business tine downloaded in advance is needed to reserve.Which is being determined
A little business tines are needed during downloading in advance, can be determined with reference to the weight of business tine, i.e., be used industry according to user
The use habit for content of being engaged in determines.For example, when using IPTV request programs, it is accustomed to according to user, the general operation of user
All it is to advance, retreats, either retract or select the channel program oneself often liked, therefore, above-mentioned program can be determined
To need the business tine downloaded in advance.When determining business tine, the range of business tine should not be excessive, also unsuitable very few,
Excessive to be easy to cause connection consumption excessive, wastes memory space, very few and cannot reflect user in time in service switchover content,
Like successional impression.It is usually no more than 5 business tines downloaded in advance.
Step 104, it is the business tine reserved storage space downloaded in advance.
It in embodiments of the present invention, can be in order to ensure business continuance of the user during service switchover content
According to business tine weight, in advance total storage size, the number of downloading service content and service rate to download in advance
Business tine determine the size of reserved storage space.
By taking IPTV program requests as an example, different types of service decides that the service of offer and toll level 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, the money of occupancy
Source is more, and rate is also higher.Meanwhile its delay requirement of different types of service is also different, for flow business, delay requirement compared with
Height, and for general ftp business, delay sensitive requires also not high.According to the grade and type of business customizing, one is reserved respectively
Fixed cushion space size.Great memory space is specifically reserved, it is comprehensive according to total cache size, business number, rate etc.
Factor accounts for.For type of service I, business pre-cache space size such as formula
Shown, wherein M represents memory space total capacity, WiRepresent service switching weight, ViExpression business i switches weight, Mi
Characterization business I downloads spatial cache amount of capacity：Such as total spatial cache size is M, the to be switched number of programs of recommendation is
N, N 3, program rate are V1, V2, V3 respectively.Program weight is W1, W2, W3 respectively.So, the pre-download space of program 1 is big
It is small to be：
Other 2 and 3 reserved storage space sizes of business program request and so on.
Step 106, the content of business is downloaded in advance according to the sequence of business tine priority weights grade from high to low pre-
The memory space stayed.
In embodiments of the present invention, after determining the business tine downloaded in advance and its reserved storage size,
During the use of current business content, the download flow for the business tine downloaded in advance can be started, download priority according to
Business weight weights are downloaded successively from big to small, this is because the possibility that uses of higher business its user of weights is also more
Greatly, therefore, it is necessary to preferentially ensure that the excessively high business of weighted value has enough spatial caches to be serviced for it.
By taking IPTV as an example, it is assumed that proportion range is defined as [1, M], and the business that wherein weight is M preferentially reserves the pre- of needs
Downloading flow space, and so on, if spatial cache is not run out, then reserved weight is the pre-download stream needed for the business of M-1
Space needed for amount.Since IPTV number of programs is excessive, it is impossible to which each business carries out pre-download, can cause to store in this way
Greatly, cost is excessively high, also unrealistic.Therefore, it sorts according to priority size, priority, that is, weighted value is bigger, preferential to download.
Optionally, in embodiments of the present invention, it is contemplated that user's custom may in different times in section there are difference, because
This, can regularly update business tine weight or reserved storage space, for example, updating its industry according to the recent use habit of user
Business weighted value, and further determine that and the business tine for needing to download in advance is updated, it is also possible to according to updated
Content is downloaded in advance is correspondingly automatically updated into its reserved memory space.
In order to which the record of more new content is better achieved, corresponding list can be safeguarded, it, can be with for example, by taking IPTV as an example
Safeguard a business and channel relation table, field is as follows in table：Channel ID, type of service, service rate, lowest tolerated time delay,
The association attributes such as service switching weight regularly update the value of above-mentioned field according to period regular hour.Wherein service switching is weighed
It is analogous to channel switching weight again, i.e. the business is by the possibility of user's program request when using IPTV service, and weighted value is bigger, quilt
The possibility for being switched to the channel is also bigger.
Although above-described embodiment is mainly illustrated by taking IPTV as an example, optionally, in embodiments of the present invention, institute
It states business and includes VOD service, interactive entertainment business, web page browsing, video communication business or instant messaging business, then
Business tine respectively includes business channels, type of play, web page address, video communication object or instant messaging type of service.It is right
In other business, for example, web-browsing service, the business weight of each web page address can be determined according to user's use habit,
For example, the web page address often accessed, the web page address accessed recently etc. can be determined that in the business for needing to download in advance
Hold, and be its reserved storage space, when user opens browser, can in advance download the content of corresponding web page address in advance
To reserved memory space, alternatively, accessing the use habit of the sequencing of web page address according to user, current accessed net is determined
The maximally related web page address of page address, and determine maximally related web page address to need the industry downloaded in advance under current accessed webpage
Business content, and downloading service content is to reserved storage space in advance when browsing current web page, in this way, working as when user needs to switch
During preceding webpage, you can be quickly switched into corresponding web page, meet the successional impression of user.
