Description

Service navigation information provision method, system, and terminal

technical field

The invention relates to the technical field of broadcast (BCAST) services, in particular to a method for providing service navigation information and a system thereof, and a terminal.

Background technique

At present, the mainstream technologies for providing mobile video broadcasting services mainly exist in the following categories:

Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service);

Broadcast Multicast Service (BCMCS, Broadcast Multicast Service); and

Handheld digital television broadcasting (DVB-H, Digital Video Broadcast-Handset) business.

The above three technologies are all based on the application layer in the mobile network architecture, and the BCAST fusion architecture proposed by the Open Mobile Alliance (OMA, Open Mobile Alliance) mainly integrates the application layers of the above three different mobile network architectures, thus Provide users with a unified business platform.

Please refer to Figure 1, which is a schematic diagram of the main components of the existing BCAST fusion architecture, in which BCAST business applications, BCAST business distribution/adaptation, BCAST subscription management and terminals in the figure are four of the BCAST fusion architecture systems The main logical entities, BCAST-1 to BCAST-8 are message channels for message interaction between the above four main logical entities; in addition, content creators, Broadcast Distribution Systems (BDS, Broadcast Distribution Systems) business distribution, broadcast distribution The system and interaction network are logical entities related to the BCAST integrated architecture system, and BDS service distribution is an optional logical entity in the BCAST integrated architecture system.

The main functions of each logical entity in the existing BCAST fusion architecture system are described in the following table:

Logical Entity Logical Entity          Major Functionality Entities in-scope of OMA BCAST BCAST business application Describes the business application of BCAST business, such as audio/video streaming, movie download, etc.

(BCAST ServiceApplication) etc.; including streaming media encoding, content protection, and interaction; it can send business-related attributes to BCAST service distribution/adaptation and BCAST subscription management; it can also generate billing information, such as from BCAST subscription management and content creators The user charging information can be obtained at any place, and legal mechanisms can be used in the generation and transmission of user charging information. BCAST Service Distribution/Adaptation (BCAST ServiceDistribution/Adaptation) Collect and send BCAST services, and perform service adaptation between BCAST Enabler (functional entity) and the underlying broadcast distribution system (BDS, Broadcast Distribution Systems); it provides file and stream distribution, service aggregation, service protection, and service navigation Generation and transmission, notification message transmission and other functions, these messages are sent to the underlying BDS after adaptation; and different adaptation functions will be adopted according to the differences of the following BDSs. BCAST Subscription Management (BCAST Subscription Management) Indicates service provision, such as service subscription and payment operations, BCAST receives service provision information and BCAST device management. It provides notification function, service protection management, content protection management, service navigation generation, communication with BDS service distribution between terminals and interaction of managing subscription information. It can also send user charging information to BCAST service applications. Terminal The user terminal equipment receives broadcast content and program support information (including: service navigation, content protection information, etc.). The user terminal can support an interactive channel, so that it can directly interact with the network for services. Entities out-of-scope of OMA BCAST Content Creation Content providing source, providing basic content description materials (such as streaming service area, etc.); BDS Service Distribution The function is to adjust the broadcasting service and send it to the BDS, and the BDS sends it to the terminal, including file distribution, stream distribution and service navigation distribution. BDS service distribution may not exist in some BDSs, that is, it is an empty entity. It can cooperate with the interactive network to implement service discovery, perform related service protection and other interactive functions with the BDS; it also works with the BDS to send content to the terminal. Broadcast Distribution System (BroadcastDistribution System) A distribution system that sends content to terminals in the broadcast channel may be provided by a system that is different from or shared with the interactive channel, such as MBMS and DVB. Interaction Network Provide interactive channel system, such as UMTS network, etc.

The standard stipulates that mobile video broadcasting services must provide users with service navigation (SG, ServiceGuide) information, where the SG information mainly includes a brief introduction to each service (maybe a certain TV channel), and the corresponding multicast Session information (multicast session information specifically includes the destination multicast IP address and port number used to transmit the program stream, the source IP address, and possibly a session identifier, etc.), so that the terminal can subscribe according to the relevant information provided in the SG certain programs or requests to watch certain programmes, etc.

The SG information may be broadcasted by the network side to all users registered with the broadcast service provider, or the user may actively request the network side to send the SG information.

At present, in the BCAST fusion architecture system proposed by OMA, users can actively request the network side to issue SG information, and when the network side receives the request from the user for requesting its SG information, it can broadcast it to all users The SG information of each user is sent to the requesting user, so that the SG information received by each user is the same, but usually the types of services that each user is interested in are different, that is, each user only wants to receive It only contains the SG information of the service it is interested in. Therefore, the way in which the network side broadcasts the same SG information to each user in the prior art will bring cumbersomeness and trouble to the user when subscribing to the corresponding service according to the relevant information provided in the SG. Inconvenience, but also a waste of network bandwidth.

Detailed ways

The solution of the present invention is mainly aimed at the fact that in the existing BCAST fusion architecture system, the network side usually provides the same SG information to multiple users, but each user generally only wants to receive the SG information containing only the services of interest to itself, resulting in At the same time, combined with the existing BCAST fusion architecture system, the BCAST Subscription Management (BSM) has already provided and stored user preference information for indicating which services each user is interested in (stored in the BSM These user preference information can provide a judgment basis for the network side to judge which services are of interest to a specific user) mechanism, and the BCAST network side is designed to provide different users with SG information that only includes the services they are interested in. The method, the system and the corresponding terminal enable users to conveniently and quickly subscribe to related services according to the received SG information containing the services they are interested in, and at the same time enable the network side to provide users with SG information only containing the services they are interested in The occupancy of network transmission bandwidth resources is reduced, thereby achieving the purpose of saving network transmission bandwidth resources.

The main realization principle and specific implementation manner of the solution of the present invention will be described in detail below in conjunction with each accompanying drawing.

Please refer to Fig. 2, which is a schematic diagram of the main realization principle processing process of the method for providing SG information of the present invention, and its main processing process is as follows:

Step S10, the user requests the BCAST service distribution/adaptation logic entity through the terminal to include the SG information of the service he is interested in;

The terminal can set the request identifier used to indicate that the request contains the SG information of the service the user is interested in in the existing service navigation request (SG Request) to be sent to the BCAST service distribution/adaptation logic entity, such as in the existing Set a request identifier in the SGRequest message sent by the terminal to the BCAST service distribution/adaptation logic entity (wherein the request identifier can be a bool quantity indicator, for example, 1 can be used to indicate that the BCAST service distribution/adaptation logic entity is required to deliver the The personalized SG information of the service that the user is interested in can be explained to the BCAST service distribution/adaptation logic entity by using 0 to indicate that the BCAST service distribution/adaptation logic entity is not required to deliver the personalized SG information containing the service that the user is interested in The user only wants to receive the part of SG information that contains the service he is interested in; then the terminal sends the SG Request message with the request identifier set to the BCAST service distribution/adaptation logic entity, so as to realize the request to the BCAST service distribution/adaptation logic entity Contains the SG information of the service the user is interested in.

Step S20, the BCAST service distribution/adaptation logic entity responds to the request sent by the terminal, and requests the user's user preference information (User Preference) from the BCAST subscription management logic entity. As mentioned above, if the BCAST service distribution/adaptation logic entity When it is recognized that the SG Request message sent by the terminal contains the request identifier used to indicate that the request includes the SG information of the service that the user is interested in, it will know that the user only wants to obtain the SG information that contains the service of interest to the user, so subscribe to the BCAST management The logical entity sends a User Preference Query message to request the BCAST subscription management logical entity to query the user preference information of the user.

Among them, the User Preference Query message sent by the BCAST service distribution/adaptation logic entity to the BCAST subscription management logic entity specifically contains the user identification information (such as user ID information) and necessary authentication information (the necessary authentication information) of the user. Authentication information mainly includes user name and password information, etc.).

Step S30, after the BCAST subscription management logic entity receives the request from the BCAST service distribution/adaptation logic entity, it queries the user's user preference information (User Preference), and feeds back the queried user preference information (User Preference) to BCAST business distribution/adaptation logic entity, combined with the above, its specific implementation process can be as follows:

The BCAST subscription management logic entity first performs corresponding authentication and authentication processing on the user identity according to the authentication information contained in the User Preference Query message sent by the BCAST business distribution/adaptation logic entity; and

After the user is authenticated and authenticated, the index corresponds to the user's user preference information (User Preference ), because the BCAST subscription management logic entity is used to manage user information in the BCAST converged architecture system, so when the user registers, the BCAST network side will store the user's user preference information in the BCAST subscription management logic entity ;

Finally, the BCAST subscription management logic entity feeds back the user preference information (User Preference) corresponding to the user indexed above in the User Preference Result message to the BCAST business distribution/adaptation logic entity, where the user queried by the BCAST subscription management logic entity The preference information (User Preference) specifically includes the service category (Class) information, type (Type) information, and genre (Genre) information of the service that the user is interested in.

Step S40, the BCAST service distribution/adaptation logic entity performs filtering processing (SG Filtering) on each service contained in the SG information sent by the existing broadcast according to the user preference information (User Preference) fed back by the BCAST subscription management logic entity, that is, according to User preference information (User Preference), the existing SG information is filtered and processed to only include the SG information of the user's interested business; the BCAST service distribution/adaptation logic entity can be included in the User Preference information fed back by the BCAST subscription management logic entity The service type (Class) information, type (Type) information, and genre (Genre) information of the user's interested business, etc., the service type (Class) of the user's interested service included in the SG and the UserPreference information that will be broadcast ) information, type (Type) information and genre (Genre) information matching at least one service is filtered out, as the service of interest to the user included in the filtered SG information.

An example will be given below to illustrate the process that the BCAST service distribution/adaptation logic entity filters the SG information sent by the existing broadcast according to the User Preference information fed back by the BCAST subscription management logic entity:

The BCAST business distribution/adaptation logic entity finds that users prefer to watch sports programs but not political programs according to the User Preference information feedback fed back by the BCAST subscription management logic entity, so that the BCAST business distribution/adaptation logic entity will replace the existing The political programs contained in the SG information are filtered out, so that the filtered SG information contains mostly sports programs and less political programs; or

The specific filtering operation is to compare the business type, type or genre with the User Preference information fed back by the BCAST subscription management logic entity for each business contained in the SG information. If the UserPreference information fed back by the management logic entity does not match, the service and its related description information (including service subscription, service access information, etc.) will be deleted from the SG.

Step S50, the BCAST service distribution/adaptation logic entity provides the remaining SG information of the service that the user is interested in after the above-mentioned filtering process to the user through the terminal, that is, the BCAST service distribution/adaptation logic entity is analyzing the SG information sent by the existing broadcast After the information is filtered, the filtered SG information containing the service that the user is interested in is sent to the terminal (SG Delivery) through the interactive network, and the terminal further displays the received SG information to the user.

In summary, it can be seen from the above processing that the method for providing service navigation information proposed by the present invention, from the user side, can enable the user to receive only the SG information containing the services he is interested in, so as to provide the service for the user to subscribe to according to the SG information. It provides a quick and convenient way, thus improving user satisfaction; at the same time, from the network side, the SG information sent through the interactive network transmission channel can save network transmission bandwidth resources because it filters out the business parts that users are not interested in.
