Embodiment
The core concept of the inventive method is: the ESG server is divided into a plurality of data blocks with the ESG content information, the data block that the record that is comprised changes is carried out version number's renewal, by mobile communications network the broadcasting service frame is sent to terminal, terminal receives only the data block that changes with upgraded edition this shop by each data block of content information and the variation of version number thereof in the basic description list of detection ESG; Perhaps ESG server data block that the record that is comprised is changed carries out indicating simultaneously when version number upgrades the identification number (ID) of the record that changes, then the record that only more changes in the new data block of terminal.
As shown in Figure 5, the renewal of electronic service guidance content information and transmission method may further comprise the steps:
Identification information (ContentID in the table 3) according to content when content information is divided in segmentation is divided.
The data block that the record that is comprised is changed is carried out version number and the identification number (ID) of the record that changes can be described by content information data when upgrading and informed terminal.
The mode of available edition number increase by 1 is carried out version number's renewal to data block, upgrades current data block with the data block of latest edition.
As shown in Figure 6, T1 refers to all the elements recording of information, comprise the shared content information record of ESG fixed time section (promptly sending the ESG data message of those days) all channels, the ESG content information is carried out data block to be divided, per 3 records (span is 3) are divided into a data block, as first data block is S1, and ignoring record quantity is 0 data block, and to each data block numbering sign.
Such as, original contents information record T1 is carried out data block according to following mode divides:
Comprise record 1, record 2, the data block S1 of record 3 is designated 1, and version number is B1.1;
Comprise record 4, record 5, the data block S2 of record 6 is designated 2, and version number is B1.1;
And the like,
Comprise record n-2, record n-1, the data block Sk of record n is designated K, and version number is B1.1;
As mentioned above, all data blocks are identified.As summary journal quantity is n, and the span of section is p, then the full middle following formula of essential part data block total number amount K: K=[(n-1)/and p]+1.
The record quantity that each data block of system configuration comprises, value is 3 in specific embodiment as mentioned above, also can be other numerical value.
Suppose that record 3 and record 5 with respect to the ESG data message of last time issue change have taken place, all records this moment (* represents change among the figure) shown in T2 among the figure.
In all data blocks, the record that is comprised does not have the version number of data block of change constant, and the data block version number that change takes place the record that comprises upgrades.In T3, the version number of data block S3 remains unchanged, data block S1, and the version number of S2 is updated to B1.2, and the ID of the record of change will be in the data block takes place server end, describes by content information data and informs terminal.In data block S1, the ID that the record of change takes place is 3, and among the data block S2, the ID that the record of change takes place is 5.
Wherein, among the B1.1 of version number, the version number of first " 1 " expression is the announcement version number that server is set, be the version number of server timing to the data available of terminal broadcasting, the version number of second " 1 " expression is the version number of data block, and the version number that hereinafter mentions is second version number.
In data updating process, if there is new record to occur, server then is assigned to it and comprises in the data block of span number that record quantity do not reach distribution, and its version number is upgraded, and terminal is upgraded synchronously according to said method.Perhaps, server end then is assigned to it in new data block, and sets version number for it, when terminal has detected new data block, carries out this data block is received.
In data updating process, when having record to delete, server end empties this recorded content, and the version number of the data block at its place is upgraded, and terminal is upgraded synchronously according to said method.
Need to prove, the data block limited amount system of dividing in the practical application, for example 256 data blocks of 8 maximum signs, so the record quantity of each data block also have minimum value, and generally much bigger than illustrated, for example span p is 1000.
Step 502 is provided with the version number and the service identification of described content information data piece in basic description list;
After step 504, terminal are received described service integration frame, detect content information data piece and version number thereof in the basic description list of ESG, change, then receive corresponding data block the local data piece is upgraded as version number.
According to the dividing mode of server, the content information record is divided into different data blocks in the terminal, what be provided with in the sign of data block and the server is identical.After terminal is received the service integration frame, detect content information data piece and version number thereof in the basic description list of ESG, do not change, then do not receive corresponding data block as version number; Change as version number, then receive corresponding data block, according to the ID of the content information record that is comprised in the data block, the content information record in the corresponding renewal local data perhaps upgrades the whole data block of this locality.
When server end carried out Data Update, number as old version number, the version number of the renewal after the variation was as new version number with the current version of data block.Data block version number shown in Figure 2 is fixed-length data (for example 4bit, available version number is 0 to 15, totally 16), and numerical value recycles.Record in some data block in the content information may remain unchanged for a long time, then can continue to use a certain version number (for example 3) long period, and the version number of the data block of change takes place and circulates along with each constantly issue new content information and increase progressively in record, when being incremented to maximum (as 15), upgrade then from minimum value (as 0) next time, continue circulation.When terminal receives, also, judge whether version number changes according to the mode of circulation.
When terminal is a kind of in the following situation, the data block of ESG server broadcast is all received:
Terminal does not have available electronic business guiding information; Terminal is according to whole reception requirements of service application needs; The version number of the issue that terminal receives and terminal buffers inconsistent.
Under the normal operating position, most of users have had the content information of last revision, terminal can be identical owing to most of data block by each data block of content information and the variation of version number thereof in the basic description list of detection ESG, only needs reception and upgrade the data block that changes.
Above-mentioned terminal has mobile multimedia receiving function and mobile communication function.
Like this, the data block of each content information is divided more rationally, helps terminal to realize the content information updating operation of ESG data easily.When terminal receives the ESG data message, according to the version number of each data block of content information in the basic description list, can determine whether receive, upgrade local ESG data message, and the decision reception all, still upgrades local content information.Receive if desired, upgrade, as the content-data behind above-mentioned the breaking the whole up into parts, reduced reception, data updated amount, terminal receives, upgrades also easier.Particularly when ESG content information data amount was big, the local content data message changed, and major part does not change, and this situation often exists, and the advantage of described method is also very remarkable, helped terminal to realize the renewal operation of ESG data easily.
The present invention aspect widely is not limited to the specific detail and the exemplary embodiments that illustrate and describe herein.Therefore, can under the condition that does not break away from by claim and the spirit or scope of the present invention that equivalent limited thereof, make various modifications.
