The user selects subscribed content through the programme that server provides.Through the DCD server platform; All kinds of service providers (SP), content supplier (CP), operator can provide abundant content to the user, and this just makes abundant, the enormous amount of type that can supply the content that the user selects, so programme is inevitable very big; And bandwidth that the mobile network can provide and transmission rate are limited; Therefore, how under band-limited situation, it is that the DCD technology needs one of problem that emphasis solves that the programme that can meet consumers' demand to greatest extent is provided.
Broadcasting (BCAST) technology is that the mobile network that passes through that Open Mobile Alliance (OMA) is formulated is broadcast to the technology of portable terminal with content, and most important applications is a mobile TV in the practical business.BCAST has formulated programme mechanism is provided: service guide (SG, Service Guide), DCD adopts this mechanism as the programme of oneself mechanism and content subscription mechanism to be provided.Fig. 1 is for the sketch map of the SG data model of BCAST formulation, and is as shown in Figure 1, and SG provides channel (Service), program (Content), program to insert information such as (Access) method, program charging to the user.SG organizes these information through sharding method, and the category information in each burst recorded program list, and each burst is organized through unified resource identifier (URI) forms complete and organizes programme flexibly.The function of each burst is following:
The channel burst is described the set of a content item, for example: central authorities one, movie download.
Content fragment is described a content, for example: the news hookup that central authorities are, the The Lord of the Rings of movie download channel.
Program arranges burst to represent the arrangement of time of down sending content and broadcast, and for example: the arrangement of time of news hookup: 19:00-19:30 plays; The arrangement of time of The Lord of the Rings: 18:00-20:00 downloads, and 21:00-23:00 plays.
Inserting burst is expressed as access service mode and the access that the terminal provides and represents this professional Capability Requirement.
The conversation description burst is represented session related information, for example: news hookup: host-host protocol, the destination address of medium type and form, starting and ending time, medium and port numbers etc.; The Lord of the Rings: source address, destination address and port numbers etc.
Buying a burst representes to buy item promptly: the least unit that the user buys, for example: one or more channels, one or more content.
The purchase data burst describe to be bought relevant specifying information, describes the purchase Channel that buys Item, for example: news hookup: 1 time 1 yuan; News hookup: obtain cost information through interactive mode;
The purchasing channel burst is described the information of buying such as mode, for example: news hookup: buy through dialing or through the purchase of sending short messages.
The preview data burst is described preview function, and for example: switch to The Lord of the Rings from news hookup, the user need not to wait for, can first preview content; In the time of user's browse service guide, can watch the preview part of content.
Each burst identifies with unique id field, and has an entry-into-force time and out-of-service time.
Channel and content fragment to content programme describe, the name of properties collection perhaps in name field is described, channel type field description type of service, as: movie channel, file are downloaded; Content type field is described the type of content, as: multipurpose internet mail extension protocol (MIME) medium type: text, audio frequency, video; The overall situation (Global) channel id field is professional unique identification, and overall content ID is the unique identification of content.
The SG data can send to user terminal through broadcast mode or point-to-point mode.For broadcast mode, the Bcast server has a proprietary frequency range timing or broadcasting SG data when programme upgrades.After the SG data of this proprietary frequency range are received at the terminal, with the SG data contrast that preserve this locality, the corresponding SG data of upgrading this locality.For point-to-point mode, the terminal can log on server, selects to hope the SG burst of renewal, with the SG data that this burst is downloaded and renewal is local.

If the processing of certain content item is wrong, also comprise the processing error information of this content item.
Step 208: the content send server detects the content item that content terminal subscribes to and can use, and at the URI of the personalizing parameters of self searching this content item that the user selectes, and then finds corresponding personalizing parameters.
Step 209: the personalizing parameters of this content item that the content send server is selected according to the user, judge that the current content that whether satisfies in this personalizing parameters sends condition, if satisfy execution in step 210; Otherwise, execution in step 211.
Step 210: the content send server sends this content item to content terminal, and this flow process finishes.
Step 211: the content send server continues to wait for to satisfying content transmission condition, goes to step 210.
Personalizing parameters among the present invention comprises that at least content sends condition, below the user among the present invention is initiated content subscription flow process, content terminal are initiated the content subscription flow process, content send server contents processing subscribes to flow process and the content send server provides the flow process of content to be described in detail respectively.
Fig. 3 is the process chart that user that the embodiment of the invention provides initiates content subscription, and as shown in Figure 3, its concrete steps are following:
Step 301: the user sends the content subscription request to content terminal, this content subscription request carry content item sign that the user will subscribe to as: channel identication and/or program identification.
In practical application, the content item sign of the electronic program list of the interface display that the user can be through the click on content terminal is initiated the content subscription request.
Step 302: after content terminal is received this content subscription request, at the URI that self reads all corresponding optional personalizing parameters of content item that the user will subscribe to.
Step 303: content terminal reads the URI of first personalizing parameters that is not read in the optional personalizing parameters in order.
Step 304: content terminal self finding this URI corresponding personalizing parameters and user interactions type, according to this user interactions type, offers the user with this personalizing parameters according to the URI that reads.
The corresponding user interactions type of each personalizing parameters; The user interactions type representes that what mode the user can adopt select personalizing parameters, and the user interactions type can be divided into: show that (Display) mode, affirmation (Confirmation) mode, user's input (User Input) mode, user select (User Choice) mode etc.Wherein, display mode representes that content terminal is shown to the user with the personalizing parameters of setting, and the user can only accept this personalizing parameters and can't carry out any operation to this personalizing parameters; The affirmation mode representes that content terminal offers the user with personalizing parameters, and the user can only select to accept or refuse this personalizing parameters; User's input mode representes that the user passes through keyboard etc. to the own definite personalizing parameters of content terminal input; User's selection mode representes that content terminal offers the user with all optional personalizing parameters, and the user is through the selected personalizing parameters of oneself accepting of modes such as click.
Step 305: the URI of the optional personalizing parameters that content terminal judges whether not read in addition, if then return step 303; Otherwise, execution in step 306.
Step 306: content terminal receives the personalizing parameters that the user selectes.
Step 307: whether the content terminal judges sends selected personalizing parameters through user's input mode, if, execution in step 308; Otherwise, execution in step 310.
Step 308: whether the grammer of the personalizing parameters that the content terminal judges is sent is legal, if, execution in step 310; Otherwise, execution in step 309.
Step 309: content terminal goes to step 306 to the information that the user returns syntax error.
Step 310: the personalizing parameters of this content item that content item sign that the content terminal recording user will be subscribed to and user select, so that initiate the content subscription flow process to server.
Write down the personalizing parameters of this content item that content item sign that the user will subscribe to and user select at content terminal after; Content terminal just can have been initiated the content subscription request to the content send server; Below be the handling process that content terminal is initiated content subscription, its concrete steps are following:
Step 01: content terminal sends the content subscription request to the content send server, and the URI of the personalizing parameters of content item sign and this content item is carried in this content subscription request.
Content terminal can be initiated the content subscription request to the content send server under two kinds of situations:
Situation one, content terminal be in the content subscription request of receiving that the user sends, and after having write down the URI of content item sign that the user subscribes to and selected personalizing parameters, initiate the content subscription request to the content send server immediately.
Situation two, content terminal are behind the URI of the personalizing parameters that the content item that has write down user's subscription identifies and selectes; The personalizing parameters of the content item of each subscription of monitoring in real time; When detecting current satisfying personalized parameter, send the content subscription request to the content send server.
The content subscription request can send to the content send server through the pull mode.
Step 02: after the content send server is received this content subscription request, write down content terminal sign, content item sign and personalizing parameters that this content subscription request is carried, and to content terminal returned content subscription response.Content subscription response comprises: content subscription request ID, to the process state information of content subscribe request further comprises: problematic content item sign and corresponding process state information.
Fig. 4 is the content send server that provides of the embodiment of the invention provides the flow chart of content to content terminal, and as shown in Figure 4, its concrete steps are following:
Step 401: the content send server detects certain content item and can use, and self is searching content terminal sign and the corresponding personalizing parameters URI of this content item that subscribes to this content item, and then is finding the corresponding personalizing parameters of this personalizing parameters URI.
When content supplier was put into this content item on the content send server, the content send server can think that this content can use.
If comprise more than a program under certain channel, to personalizing parameters separately should be arranged, channel self is also to there being personalizing parameters respectively for each program, and the priority of the personalizing parameters that then program is corresponding is higher than the priority of the corresponding personalizing parameters of channel.When program and channel did not all have corresponding personalizing parameters, the content send server was with the personalizing parameters of self acquiescence personalizing parameters as this program.
Therefore; In this step; If the content send server detects certain program and produces; Then the content send server is specially at the URI of the content terminal of self searching this program of subscription for the selected personalizing parameters of this program: the content send server is in the corresponding relation of the terminal iidentification of self preserving, content item sign and personalizing parameters URI; Search the URI of the corresponding personalizing parameters of this program, if find, then with the URI of this personalizing parameters that finds personalizing parameters URI as this program; If do not find; Then at the corresponding personalizing parameters URI of channel that self searches under this program; If find; Then with the URI of this personalizing parameters that finds personalizing parameters URI, if do not find, then with the personalizing parameters URI of self acquiescence personalizing parameters URI as this program as this program.
If the content send server detects certain channel and produces; Then the URI for the selected personalizing parameters of this channel is specially the content send server at the terminal of self searching this channel of subscription: the content send server is in the corresponding relation of the terminal iidentification of self preserving, content item sign and personalizing parameters URI; Search the URI of the corresponding personalizing parameters of this channel; If find, then with the URI of this personalizing parameters that finds personalizing parameters URI as this channel; If do not find, then with the personalizing parameters URI of the personalizing parameters URI that self gives tacit consent to as this channel.
Step 402: the content send server judge this personalizing parameters be time-based condition, based on the condition of incident, also be based on the condition of threshold value, if time-based condition, execution in step 403; If based on the condition of incident, execution in step 406; If based on the condition of threshold value, execution in step 408.

Step 407: the state notifying that the content send server takes place to this incident of content terminal customization,, this incident notifies self to require content terminal when taking place.
Step 408: the content send server is received the state notifying that this incident that content terminal is sent has taken place, execution in step 409.
Step 409: the content send server sends this content item to content terminal, and this flow process finishes.
Step 410: the content send server is judged the current condition that whether satisfies this based on threshold value, if, execution in step 413; Otherwise, execution in step 411.
Based on the condition of threshold value for example: terminal memory size threshold value, CPU usage threshold value, network signal intensity threshold value etc., through the DPE technology, the content send server can customize corresponding threshold value, when threshold value arrives, content terminal report content send server.
Step 411: the content send server is notified self to require content terminal to the state notifying that this threshold value of content terminal customization arrives when reaching this threshold value.
Step 412: the content send server is received the state notifying of the threshold value arrival that content terminal is sent, and goes to step 413.
Step 413: the content send server sends this content item to content terminal.
Further; If the number of personalizing parameters is more than one; As: for time-based condition with based on the condition of incident; Or be time-based condition and based on the condition of threshold value, then must be when the condition of all personalizing parameters indications be all set up, the content send server could send content item to content terminal.If the number of personalizing parameters is more than one; And there is conflict between the personalizing parameters; As: the property parameter is one by one: be higher than transmission in 70% o'clock at CPU usage; Another personalizing parameters is for to be higher than transmission in 60% o'clock at CPU usage, and then when the condition of the high personalizing parameters indication of priority was set up, the content send server just sent content item to content terminal.
