An Internet Protocol Multimedia Subsystem (IMS) is a Subsystem supporting Internet Protocol (IP) Multimedia services proposed by the Third Generation Partnership Project (3 GPP). IMS is an IP-based standard network independent of the access technology, interoperable with existing voice and data networks. The IMS network may perform functions such as session management, registration, security, charging, bearer control, or roaming.

Internet Protocol Television (IPTV) is a brand-new technology that uses a broadband cable Television network, integrates various technologies such as Internet, multimedia, communication, and the like, and provides various interactive services including digital Television to home users. The user can use a Personal Computer (PC) at home, can enjoy the IPTV service by using a network set-top box and a general tv, and can enjoy the IPTV service through a mobile terminal. The IPTV uses Transmission Control Protocol (TCP)/IP as a bearer Protocol to perform unicast, broadcast or multicast video services, effectively combines the three fields of the television network, the telephone network and the internet, is the most representative service of the integration of three networks, and is receiving more and more attention in the industry. IPTV based IMS network (IPTV based IMS network) service is also a focus of attention in recent years.

With the upgrading and development of information technology, information transmitted on the internet at present only includes characters or pictures, and may also include animation, films, music or voice effects, so called rich media, which generally includes contents in various formats such as two-dimensional and three-dimensional pictures (Image), Video (Video), Audio (Audio), HyperText Markup Language (HTML), Flash memory (Flash), Dynamic HTML (Dynamic HTML, DHTML) and JAVA, and has the greatest characteristic of providing interactivity, improving audience participation, and improving user experience.

Fig. 14 is a flowchart of a method for generating a rich media scene according to another embodiment of the present invention, which describes an implementation process of the method for generating a rich media scene provided in the embodiment of the present invention under the IPTV architecture based on the IMS network shown in fig. 13. As shown in fig. 14, this embodiment includes:

step 1401, the UE sends the interaction information of the real-time service to the SCF entity.

For example, in an interactive voting system, the interactive information of the real-time service sent by the UE is voting information, and the voting data included in the voting information is data required for generating a rich-media scene file or an update file. The voting information may be an XML file, for example, as follows:

<vote>

<channel id＝″5″>

< program > super-female Final Drive The program >

</channel>

<from>iebhchen@example.docmain.com</from>

<to>LiYuchun</to>

<to>ZhangLiangying</to>

</vote>

Step 1402, the SCF entity generates an indication message according to the interaction information of the real-time service, where the indication message includes data required for generating a rich media scene file or an update file, and a service type of the real-time service.

Specifically, the format template adopted by the interactive information of the real-time service sent by the UE is related to the service, and is preset, so that the SCF entity can determine the service type of the real-time service according to the interactive information of the real-time service sent by the UE.

In step 1403, the SCF entity sends an indication message to the MCF entity.

In step 1404, the MCF entity relays the indication message to the DSC function module in the MDF entity.

Step 1405, optionally, the SCF entity sends the indication message directly to the DSC function module in the MDF entity through the interface X1.

In step 1406, the DSC function module in the MDF entity generates a rich media scene file or an update file corresponding to the service type in the indication message according to the data in the indication message.

In step 1407, the DSC function module in the MDF entity returns the storage location information of the generated rich media scene file or update file to the SCF entity. And then, the SCF entity can issue the storage location information to the UE, and the UE downloads the rich media scene file or the update file from the DSC function module according to the storage location information.

Specifically, a DSC function module in the MDF entity may return the storage location information of the rich media scene file or the update file to the SCF entity through the MCF entity; it can also be realized by adding interfaces such as: the interface X1 returns the storage location information of the rich media scene file or the update file directly to the SCF entity.

In step 1408, the MDF entity issues a rich media scene file or an update file to the UE.

Specifically, the MDF entity may also issue the rich media scene file or the update file to the UE in a streaming or UE downloading manner; the MDF entity may also package the rich media scene file or the update file sent by the DSC into an RAP, and then issue the RAP to the UE in a streaming or UE downloading manner.

The embodiment of the invention realizes the real-time dynamic generation of the rich media scene file or the update file in the process of providing the rich media service by introducing the DSC under the IPTV architecture based on the IMS, realizes the real-time dynamic update of the rich media scene, thereby realizing the provision of the rich media service under the IPTV architecture based on the IMS network, enhancing the interaction capacity of the IPTV based on the IMS network, improving the participation degree and the user experience degree of audiences, and enriching and expanding the service range of the IPTV. The embodiment of the invention provides various flexible implementation schemes for the specific configuration of the DSC in the network.
