Description

A dynamic content transmission method and system

technical field

The invention relates to the communication field, in particular to a dynamic content transmission method and a dynamic content transmission system.

Background technique

Dynamic content delivery is a client/server based technology for delivering personalized content to mobile end users. After the user customizes the content, the server will personalize the content according to user parameters, user location, online status, etc., and transmit the content to the user terminal at regular intervals.

In the prior art solution, the process of content delivery includes the following steps:

The terminal uses the Hyper Text Transport Protocol (Hyper Text Transport Protocol, HTTP) or the Wireless Access Protocol (Wireless Access Protocol, WAP) to send a dynamic content delivery request to the Dynamic Content Delivery (DCD) server through the Request message. The request carries terminal capability information; the terminal capability information follows the User Agent Profile (UAProf) standard, and the terminal capability information does not include terminal storage space status information;

After receiving the dynamic content transmission request sent by the terminal, the DCD server parses the requested content and terminal capability information, and processes the requested dynamic content according to the user's setting parameters and terminal capability information; including: changing the length of the video content, and intercepting the text content A certain part of the image content, adapting the resolution of the image content, etc., to generate the content to be sent;

The DCD server uses the HTTP protocol or the WAP protocol to send the content to the terminal through a response (Response) message;

The terminal receives the content and stores the content in the local storage space at the same time;

If the local storage space is insufficient, the terminal prompts the user, and terminates the dynamic content delivery session with the DCD server.

The shortcoming of above-mentioned prior art is as follows:

The DCD server and the terminal do not compare the size of the transmitted content with the available storage space of the terminal before the dynamic content transmission starts. When the size of the transmitted content is larger than the available storage space on the terminal, the transmission will still start. When the storage space on the terminal is exhausted , the transmission is interrupted, resulting in the eventual inability to complete the content transmission. Therefore, in the prior art solution, the personalized dynamic content is directly sent to the terminal without considering the available storage space of the terminal. When the available storage space of the terminal is smaller than the size of the dynamic content to be transmitted, the transmission cannot be completed, resulting Waste of network transmission bandwidth. In addition, since the personalization process consumes a lot of DCD server system resources, if it is discovered after the personalization process that the transmission cannot be completed normally due to the size of the available storage space of the terminal, it will cause a waste of DCD server system resources.

Detailed ways

The present invention provides a method for sending dynamic content, which includes: obtaining the available storage space of the terminal device by the DCD server; processing the dynamic content sent to the terminal device according to the available storage space of the terminal device; when the processed dynamic content When the dynamic content can be stored in the available storage space of the terminal, the dynamic content is sent to the terminal device.

The method of the present invention will be described in detail below in conjunction with the accompanying drawings.

According to different triggering modes for sending dynamic content, it can be divided into two cases: initiated by the terminal device and initiated by the DCD server.

Example 1:

The terminal device initiates a dynamic content transmission request, and reports the status information of the terminal storage space to realize dynamic content transmission.

See Figure 1, the specific steps include:

Step 1, the terminal device sends a Request message to the DCD server using HTTP or WAP protocol, requesting to send dynamic content, carrying extended terminal capability information (extended UAProf or DPE), which includes terminal storage space status information;

To extend UAProf or DPE is to add an <AvailableStorage> sub-element to <HardwarePlatform> in UAProf in the prior art. The structure of the extended UAProf or DPE and the location of the terminal storage space information are described by the following bold statement:

</rdf: Description>

</rdf:RDF>

Step 2. After receiving the dynamic content sending request, the DCD server performs the following processing:

First, the DCD server determines the size of the available storage space of the terminal device according to the status information of the terminal storage space carried in the request message;

The DCD server compares the available storage space of the terminal device with the size of the dynamic content; when the available storage space of the terminal device is smaller than the size of the dynamic content, the dynamic content is personalized by reducing the size of the dynamic content; otherwise, the dynamic content is directly processed content personalization;

There are various ways to reduce the size of dynamic content, such as:

(1) Compress the dynamic content, such as: compress the 800*600 picture to 640*480 to reduce the amount of information stored in the picture in the dynamic content, so that the compressed dynamic content can meet the available storage capacity of the terminal device size of space;

(2) Carry out cut processing to dynamic content, as: cut off the opening song and ending song part of the movie, the multimedia content in the webpage is removed, the netizen comment part after the news item and Blog is removed, etc.;

(3) store the dynamic content as files in different formats, and select the corresponding file with the smallest number of stored bytes for processing;

(4) A certain value is used as an input parameter of a personalization engine, and the processing result of the personalization engine must meet the requirement that the size of the processed file is smaller than this value; It can be stored in the available storage space, and the range of this value is less than or equal to the available storage space of the terminal.

The above four processing methods can be used alone, or multiple processing methods can be used at the same time.

In a specific implementation process, one or more corresponding processing methods may be preset and stored in the DCD server according to different types of dynamic content. When the dynamic content needs to be processed, a corresponding processing method is used for processing according to the type of the dynamic content. For example: when the dynamic content type is an image file, you can choose the above processing method (1) and processing method (3), first compress the image, and then store the compressed image as a . jpg file format, etc.

Step 3. The DCD server sends the personalized dynamic content to the requesting terminal device through a response message.

If the size of the dynamic content processed by the above-mentioned various processing methods is still larger than the available storage space of the terminal, the DCD server may delay or cancel sending the dynamic content to the terminal device.

In the specific implementation process, the delay time can be preset in the DCD server; within the delay time, the DCD server periodically obtains the available storage space of the terminal device, and when it is judged that the available storage space of the terminal device is greater than or equal to the size of the processed dynamic content hour, start sending the dynamic content to the terminal device immediately; when the delay time reaches, the available storage space of the terminal device is still smaller than the size of the processed dynamic content, cancel sending the dynamic content to the terminal device.

In addition, for some instant dynamic content, such as stock information, etc., if the dynamic content cannot be sent to the terminal device at present, the sending is directly canceled.

Example 2:

The terminal device does not carry the terminal storage space state information when it initiates a dynamic content transmission request, and the DCD server realizes dynamic content transmission after obtaining the terminal storage space state information from the terminal device.

See Figure 2, the specific steps include:

Step 1. The terminal device sends a Request message to the DCD server, requesting to send dynamic content; the sent Request message does not include terminal storage space status information;

Step 2. After the DCD server receives the request for sending the dynamic content, it sends an inquiry message to the terminal through ShortMessage Service (ShortMessage Service, SMS) or push (PUSH), requesting to obtain the status information of the terminal storage space;

Step 3, the terminal replies a response message to the server via SMS, and reports the status information of the terminal storage space in the response message;

The query/response message can be bound to the options (OPTIONS) in the Session Initiated Protocol (Session Initiated Protocol, SIP). The following is a specific example of the query message:

OPTIONS DPE: <destinationURI>SIP/2.0

Via:...

Max-Forwards: 70

To: <destinationURI>

From: <SourceURI>; tag=1928301774

Call-ID: a84b4c76e66710

CSeq: 63104 OPTIONS

Contact: <contactURI>

DPEElement: Description/component/HardwarePlatform/AvailableStorage

Content-Length: 0

The following are specific examples of response messages:

SIP/2.0 200 OK

Via:...

To: <destinationURI>; tag=93810874

From: <SourceURI>; tag=1928301774

Call-ID: a84b4c76e66710

CSeq: 63104 OPTIONS

Content-Type: application/DPE

<prf:AvailableStorage

      rdf:datatype=″&prf-dt;Number″>2MB</prf:AvailableStorage>

</rdf: Description>

</prf:component>

</rdf: Description>

</rdf:RDF>

Therefore, it is necessary to support the DPEElement header field (such as the thick black statement above) in the OPTIONS message of SIP, and its semantics is to specify the element (element) in the DPE file that must be included in the response message; a new Multipurpose Internet Mail Extension needs to be registered (Multipurpose Internet MailExtensions, MIME), the type is application/DPE; DPE content is carried in the SIP response.

MIME is an e-mail technical specification widely used at present, and its basic content is defined in RFC2045-2049. In MIME, different content types must register a name, so that content receivers know the specific type of multimedia content received. The above response message includes: Content-Type: application/DPE; indicating that the content carried in the message is a DPE content.

Step 4. After receiving the response message, the DCD server determines the size of the available storage space of the terminal device according to the storage space status information carried in the response message; the following processing is the same as step 2 in the flow chart of FIG. 1 and will not be repeated.

Step 5 is the same as step 3 in the flow chart of Figure 1, and will not be repeated.

Example 3:

The terminal device initiates a dynamic content transmission request, and the DCD server acquires terminal storage space status information from the DPE server to implement dynamic content transmission.

Referring to FIG. 3 , the DCD server can acquire the terminal storage space status information of the terminal device from an external entity; the DCD server acquires the terminal storage space status information from the DPE server as an example below.

The DPE server is connected to the terminal device, and communicates with the terminal device in real time to obtain the dynamic capability information of the terminal device; when the dynamic capability of the terminal device changes, the DPE server updates the locally stored dynamic capability information of the terminal device in real time.

The specific signaling process includes:

Step 1. The terminal device sends a Request message to the DCD server, requesting to send dynamic content; the sent Request message does not include terminal storage space status information.

Step 2. After the DCD server receives the dynamic content sending request, it sends an inquiry message to the DPE server terminal, requesting to obtain terminal storage space status information, and carries the identification information of the terminal in the inquiry message;

The DCD server can also send a subscription message to the DPE server, with a terminal identifier in the message; for example, the RFC3265 subscription/notification mode is adopted.

Step 3. After the DPE server receives the inquiry message, it sends a response message to the DCD server, and reports terminal capability information in the response message, which includes terminal storage space status information;

If the DPE server receives the subscription message sent by the DCD server, it sends a notification message to the DCD server, and reports terminal capability information in the notification message, which includes terminal storage space status information.

Extend the subscription (SUBSCRIBE)/notification (NOTIFY) message in SIP to support DPE. The following is an example of a subscription message:

SUBSCRIBE DPE: <destinationURI>SIP/2.0

Via:...

Max-Forwards: 70

To: <destinationURI>

From: <SourceURI>; tag=1928301774

Call-ID:...

CSeq: ...NOTIFY

Contact: <contactURI>

DPEElement: Description/component/HardwarePlatform/AvailableStorage

Content-Length: 0

The following is an example of a notification message:

NOTIFY DPE: <destinationURI>SIP/2.0

Via:...

To: <destinationURI>; tag=93810874

From: <SourceURI>; tag=1928301774

Call-ID:...

CSeq: ...NOTIFY

Contact: <contactURI>

Content-Type: application/DPE

Content-Length:...

Therefore, it is necessary to support the DPEElement header field in the SUBSCRIBE message of SIP, and its semantics is to specify the element in the DPE file that must be included in the response message; a new MIME type needs to be registered, which is application/DPE; carried in the NOTIFY message of SIP DPE content.

Step 4. After receiving the response message/notification message, the DCD server determines the size of the available storage space of the terminal device according to the available storage space status information carried in the response message/notification message; Same, no restatement.

Step 5 is the same as step 3 in the flow chart of Figure 1, and will not be repeated.

Example 4:

The DCD server initiates dynamic content transmission, first inquires terminal storage space status information from the terminal device, processes the dynamic content according to the available storage space of the terminal device, and then sends the dynamic content.

Specific steps include:

Step 1. The DCD server sends an inquiry message to the terminal device, requesting to acquire terminal storage space status information of the terminal device;

Step 2, the terminal device returns a response message, carrying the status information of the terminal storage space;

Step 3. After receiving the response message, the DCD server determines the size of the available storage space of the terminal device according to the status information of the available storage space carried in the response message; the subsequent processing is the same as step 2 in the flow chart of FIG. 1 and will not be repeated.

Step 4 is the same as Step 3 in the flow chart of Figure 1, and will not be repeated.

Example 5:

The DCD server initiates dynamic content transmission, asks the DPE server for terminal storage space status information, processes the dynamic content according to the available storage space of the terminal device, and then sends the dynamic content.

Specific steps include:

Step 1. The DCD server sends an inquiry message to the DPE server, requesting to obtain terminal storage space status information, and carries the identification information of the terminal in the inquiry message;

The DCD server can also send a subscription message to the DPE server, with a terminal identifier in the message; for example, the RFC3265 subscription/notification mode is adopted.

Step 2. After the DPE server receives the inquiry message, it sends a response message to the DCD server, and reports terminal capability information in the response message, which includes terminal storage space status information;

If the DPE server receives the subscription message sent by the DCD server, it sends a notification message to the DCD server, and reports terminal capability information in the notification message, which includes terminal storage space status information.

Step 3. After receiving the response message/notification message, the DCD server determines the size of the available storage space of the terminal device according to the storage space status information carried in the response message/notification message; the subsequent processing is the same as step 2 in the flow chart of Figure 1 , without restatement.

Step 4 is the same as Step 3 in the flow chart of Figure 1, and will not be repeated.
