Embodiment
For above situation, the present invention proposes a kind of transmission plan of broadcast data, and proposes the sending and receiving device realizing the program.By technical scheme of the present invention, front end sends customizing messages file and pushing service guide (the Push Service Guide such as content category message, transmitting time table by broadcast mode, referred to as PSG) file bag, terminal obtains the corresponding relation of flag and business categorizing from the sort file of PSG; From the time file of PSG, respectively broadcast the ID of business, the time started of timing receipt and broadcast duration, the business timing receipt that terminal is being selected by step.Terminal obtains the attribute informations such as title, keyword, summary, file number from contents attribute file, according to this by file sheet composite document block until synthesize whole file, imperfectly can realize file subsequent collection when data replay if receive, solve that terminal classification is subscribed to, the technological difficulties such as reception, power saving are selected on backstage.
Specific embodiments of the invention will be described in detail below.
According to embodiments of the invention, provide a kind of transmission method of broadcast data.
As shown in Figure 1, comprise according to the transmission method of the broadcast data of the embodiment of the present invention:
Step S101, PSG information is sent to terminal by network side, and wherein, PSG information comprises content category message, down sending content temporal information and content attribute information;
Step S103, when terminal is subscribed to content by classified information, terminal receives the business tine file of the content of this subscription according to the down sending content temporal information of the content of subscribing to and content attribute information.
By means of above-mentioned process, terminal can be subscribed to needing the classification of subscribing to according to content category message, when receiving the file of content, optionally can receive the business tine file corresponding to content subscribed to, thus decrease network overhead, reduce transinformation, make user can watch the service scripts oneself subscribed to, improve Consumer's Experience, and, because terminal has carried out the subscription of content, therefore the actual data volume received can reduce, thus reduce the possibility again received because of taking defeat, obviously can also shorten the time that terminal carries out data receiver, thus reduce the power consumption of terminal, contribute to the portability improving terminal, extend the useful life of terminal and battery.
Wherein, content category message may correspond in sort file ContentClassification.xml, for describing the classification of each content, and for representing the corresponding relation of classifying content and classifying content rank.Ucl_class in ContentClassification.xml file is classifying content rank, is divided into level Four.Ucl_class_levelno naming rule is: ucl_class_levelno totally 6, as the flag of classifying content.1st bit-identify first-level class, the 2nd bit-identify secondary classification, the 3rd, 4 bit-identify reclassifies, the 5th, 6 bit-identify level Four classification.
In addition, down sending content temporal information (such as, can be down sending content temporal information table) may correspond in time file ContentSchedule.xml, for describe following one of at least: the time started that each business tine file issues, broadcast duration, service identification that business is broadcast and local time zone information; Further, down sending content temporal information is also for representing the corresponding relation of each content identification in business tine file number and classification stage alias.TimeZone in ContentSchedule.xml file represents that local zone time offsets, syntax rule is: 6 bit fields (binary system), highest order instruction time zone polarity, when putting ' 0 ', represent that local zone time is early than the UTC time, when putting ' 1 ', represent that local zone time is later than the UTC time.Rear 5 bit representation time offset, span 0 ~ 24, unit is 0.5 hour.ContentID in ContentSchedule.xml file is content identification number, is generated by front end system, can not repeat in 72 hours, with particular content one_to_one corresponding.StartTime represents and is made up of the time started that business tine issues date and time.Duration represents that content broadcasts duration, and unit is second.
The corresponding ContentAttribute.xml file of content attribute information of each content, for describing the quantity of business tine file corresponding to this content, and can further describe the information such as title, keyword, summary of file.Title in ContentAttribute.xml file represents content title, and Keyword represents content-keyword, and Abstract represents summary, and Fileno represents the file number of this content bag.
Further, for the content of each subscription, after the business tine file reception of this content, the quantity of the business tine file in content attribute information corresponding with this content for the quantity of the business tine file of reception compares by terminal; If the quantity of the business tine file received is less than the quantity of the business tine file in content attribute information (now, the file of this content is not all received by terminal), then terminal determines the business tine file reception failure of this content, and again receives according to the business tine file of down sending content temporal information to this content of this content in PSG information.It should be noted that, issue temporal information except can specifying the moment of repeating transmission, also can in conjunction with other mode, such as, for important content file, the mode at every turn sent can be configured to " sending N time (N is greater than 1) continuously ", this mode can represent each time sending the business tine file of this content equally, and which is equally in the scope of the application.
In the related, when receiving broadcast data, probably because a small data incompleteness has to heavily receive or repeatedly receive identical content, long-time reception data can increase the power consumption of terminal, reduce portability and the life-span of mobile terminal, and by again receiving the file of the content of unsuccessful reception selectively, effectively can shorten the time that terminal carries out broadcast data reception, reduce power consumption, extend the useful life of terminal.And heavily received by the business tine file of selectivity to bust this that the present invention proposes, effectively can ensure that terminal receives ordered business tine, improve the reliability of transfer of data, and can ensure that terminal receives only data a small amount of as far as possible in the heavy time receiving, thus avoid the heavily receipts of data obviously can increase power consumption of terminal and data receiver problem consuming time.
In addition, the content category message in PSG information, down sending content temporal information are passed through predetermined policy and are issued by predetermined dedicated channel (such as, can be special service channel).
In addition, for each content, the content attribute information of this content is together with the business tine file of this content, and the down sending content temporal information according to this content is issued to terminal.Be packaged in concrete transmission service content file Bao Lisui road to issue.
That is, when terminal receives content category message and down sending content temporal information, do not receive business tine file and the content attribute information of involved content, and when receiving content attribute information, corresponding business datum file will be received.
In addition, for the content of each subscription, when terminal starts the business tine file receiving this content, the business tine file of reception is stored in the temporary folder of terminal and preserves; When the ratio that the business tine file of this content finishes receiving completely or finishes receiving at the end of time of reception reaches the first predetermined ratio threshold values or the ratio that finishes receiving in receiving course reaches the second predetermined ratio threshold value, the business tine file of this reception is transferred to other specified folders by terminal, wherein, the file of specified folder is visible to user, and can accessed by the user (such as, user can browser document content, also can carry out the operations such as deletion to file); In addition, the first and second above-mentioned predetermined ratio threshold values can be arranged flexibly, and the first predetermined ratio threshold value can be identical or different with the second predetermined ratio threshold value.
That is, in the business tine file reception process of a content, if the business tine file reception of this content is smooth, terminal use just can see the business tine of reception, the partial document do not received can continue to receive afterwards, thus enable user watch/uppick broadcast as early as possible, improve Consumer's Experience further.
In addition, network side upgrades PSG information with predetermined time interval, and the PSG information after upgrading is sent to terminal; When the PSG information that terminal is preserved is different from the PSG information after renewal, terminal utilizes the PSG information received to replace the PSG information of preservation originally.
The operation flow of multi-medium data reception will be described in detail below.
In order to realize Mobile Multimedia Broadcasting data content categorizing selection receive and automatic reception time, as shown in Figure 2, data-pushing flow process is as follows: get the subscription programs list information returned, afterwards in filter information data inserting storehouse, generate the data manipulation list of subscribing to, the timer of setting response afterwards, and perform timer and wake the operations such as terminal, response data reception/stopping, file transfer up, and readjustment result is turned back in database.
Fig. 3 shows the specific implementation flow process of the data broadcast service according to the embodiment of the present invention.As shown in Figure 3, specific implementation process is as follows:
First, starting up of terminal performs " obtaining PSG " task;
Now, terminal checks whether and need upgrade the list of PSG Push Service; If the list of PSG Push Service needs to upgrade, then do not do any operation, continuation order performs following steps; If the list of PSG Push Service mustn't need newly, then user upgrades subscription information;
Terminal obtains and resolves PSG, upgrades PSG push classification chained list and push Task-list according to PSG data message;
Upgrade PSG according to the timing of PSG update mechanism and push task list, return step 2;
PSG classified information is passed to client by interface by terminal, wherein, here it is modular unit integrated in terminal that client can be understood as, and also can be mounted in the application in terminal, client can realize the basic function that broadcast subscription selection etc. relates to broadcasting service;
User upgrades subscription information;
Terminal subscribes to the content designator in classification by user, generate and push subscription table;
Primary data process, generates and pushes table and file traversal lists;
Enactment document transfer timer, according to the data-pushing task list setting initial timing device time;
Terminal receives data on time, needs the contents attribute file of resolving in PSG to carry out content designator contrast when receiving an assignment.If correspondence, receive, if not corresponding, abandon;
When terminal completes and receives data, need judge that successful receiving rate shifts data;
Determine whether last task, if it is close chip and stop data receiver;
If not then judging whether the interval time of next task is greater than 5 minutes, if be more than or equal to 5 minutes, chip dormancy time is set; Just next task is received according to propelling movement task list if be less than 5 minutes.
To sum up, mainly comprise classification subscriptions according to the solution of the present invention, data receiver, optimization heavily receives and identify these aspects, time zone, also relate to PSG renewal administrative mechanism in addition.
Wherein, classification is subscribed to and is mainly referred to that terminal is when receiving data-pushing business, carries out classification subscribe to by the reception classifying content obtained in PSG information;
Data receiver mainly refers to the subscription information and content reception time of being classified to PSG by user, and terminal realizes effectively receiving at special time the object customizing file.

Specifically these aspects will be described in detail below.
(1) classification is subscribed to
Comprise four flow processs during terminal processes classified information to be respectively: obtain classified information, upgrade classified information, transmit classified information and safeguard subscription information.
(1) classified information is obtained
PSG obtains and refers to log-on data stream and by resolution data stream, obtain PSG list.Obtain subscription information refer to the ContentClassification.xml file that obtains in PSG and resolve.By specific channel parameter (define this parameter in practical application be broadcast channel service identifiers (ServiceID) be 8000), set up data channel and obtain related data, and by PSG data protocol, the Push Service list that the Data Analysis got is obtained.This flow process relates to the following correlation module of terminal: task manager, data management system, PSG manager, PSG receiver.The mutual sequential chart of concrete module as indicated at 4.Processing procedure shown in Fig. 4 is as follows:
Task that task manager performs " obtaining PSG ", and transmit relevant parameter to data management system;
Data management system transmits " obtaining PSG " order and parameter to PSG manager;
PSG manager checks whether to there is Push Service list.If Push Service list exists, then do not do any operation, continue to perform subsequent step; If Push Service list does not exist, then obtain PSG receiver, and transmit relevant parameter to it;
PSG receiver receives Push Service list, and upgrades local Push Service list;
PSG manager returns execution result to data management system;
Data management system returns execution result to task manager.
(2) classified information is upgraded
For renewal and the amendment of class of fit information, according to the regulation of PSG update mechanism, timing upgrades PSG and subscribes to class table.The content upgraded comprises classifying content in PSG and down sending content time: ContentClassification and ContentSchedule.This flow process relates to the following correlation module of terminal: task manager, data management system, PSG manager.As figure 5 illustrates, process is as follows for particular flow sheet:
According to PSG update time, the logical channel that ServiceID is 8000 is opened in timing;
Receive and resolve the PSG data message of this passage;
Upgrade PSG according to PSG data message push classification chained list and push Task-list;
Having upgraded rear closedown ServiceID is the logical channel of 8000.
(3) classified information is transmitted
Send parsing acquisition PSG content category message to client by interface to show.Interface function is as shown in the following Table 1:
Table 1
Its program language is expressed as follows:
(4) subscription information is safeguarded
Client is by the classified information after display parsing, and user is undertaken choosing subscription by personal like, adds, revises or cancel the classifying content needing reception.Client-side interface, processes the sort pass that user subscribes to general layer.Terminal passes through the content designator (ContentID) in the subscription classification transmitting, generating needs the ContentID of timing receipt to show, and the down sending content time list (ContentSchedule) contrasting PSG record each ContentID task issue the time.Timer receives according to the time advance 30s initiating task that issues of the task of reception, and according to the situation receiving data in real time or afterwards task completion time 30s shift and receive content.All ContentID task lists all can be real-time the subscription information according to client user link.All interpolations for subscription information, amendment, cancellation and preservation are all managed by PSG administration module.
