The method can be used in the system containing the functional control module IPTV service, the functional module management services and transport function module. This method can be carried out above the functional control module IPTV service or system to disseminate information.

Figure 4 shows a functional diagram of a method of distributing information based on IPTV according to one variant of implementation of the present invention. As shown in figure 4, the method of disseminating information based on IPTV according to one variant of implementation, the crust is asego invention mainly includes the following steps (S402-S404):

Step S402, in which the functional control module IPTV service passes the request to initiate a communication session for transmitting the broadcast information of the subscriber equipment via the function module management services, and identification of the above information contained in this request for initiating a communication session; and

Step S404, in which the user equipment receives the request to initiate a communication session, and after the decision to accept the above-mentioned broadcast information interacts with the transport functional module according to the identification contained in the request to initiate a communication session, for the connection of subscriber equipment channel group broadcast containing information corresponding to the specified identification, and receive a stream of multicast.

Next will be described in detail above steps.

(I) Step S402

This step includes the following two stages.

Stage 1: functional management module IPTV service passes the request to initiate a communication session to the functional module management services, with a request to initiate a communication session contains the identification of the recommended information and a list of identifying information with the unique identifier of the subscriber's equipment, pointing in front of the Chu above request to initiate a communication session, at least one subscriber equipment corresponding to at least one identifier specified in the list of identifying information, for suggestions subscriber equipment to reproduce the recommended information.

Preferably in the request to initiate a communication session, the IPTV may also provide descriptive information related to the recommended information, such as information describing television programs such as news, sports or interviews.

In practice, to increase the informative recommendations, the lack of which leads to frequent requests of users, functional control module IPTV service analyzes what type of programs the user is likely to prefer according to the preferences of the content selected by the subscriber equipment, the recommendation information to the user preferred type, or functional control module IPTV service recommends users of information, the rating of appeals to which at the moment is the most high.

Stage 2: functional module management services shall send the above request to initiate a communication session, the subscriber equipment, which corresponds to each identifier included in the list identificarse the information which is contained in the request to initiate a communication session.

Practically, the above information may be service direct broadcast. If the above information is a service of the live broadcast, a request to initiate a communication session may contain the following information:

information about the identifier of the distribution, indicating that the recommended service direct broadcast is a program of direct broadcast channel, which is subject to direct review, not a media file or media stream, which is usually recorded, or is a program for distributing video on demand;

information describing the content of the programs live broadcast, such as the program name, the names of the leading actors or Actresses, a brief description of the plot and so on; and

duration, start time or end time of the broadcast program.

In addition, if the recommended information is a service of the live broadcast, a functional module management service IPTV transmits the above-mentioned request for initiating a communication session, the subscriber equipment before you begin be transmitted direct TV program proposed by the service live broadcast.

(II) Step 404

After the transfer of functional control module above mentioned request iniciar is of a communication session, the subscriber equipment, in need of advice, subscriber equipment, accepted a request to initiate a communication session, decides whether to accept the information of the recommended functional control module IPTV service, in accordance with the prior configuration or selection of a user, and transmits the function module service management IPTV solution in response to the above request for initiating a communication session by a function module management services. The functional control module IPTV service decides on the basis of information contained in the response message, agrees whether the user equipment to receive the above-mentioned broadcast information.

After the decision regarding the admission of the above-mentioned broadcast information, the user equipment transmits the connection request to channel multicast reception information corresponding to the identifier of the transport functional module in accordance with the identifying information contained in a received request to initiate a communication session. Subscriber equipment connected to channel multicast containing this information by interacting with the transport functional module and receives streams of multicast transmitted tra the transport functional module, to play the above information.

Practically, if the user equipment agrees to accept the above-mentioned broadcast information between subscriber equipment and a functional control module IPTV service must be exchanged signals for reservation of resources needed to transmit the flow information content. This process can be accomplished in two ways :

Method 1: the user equipment initiates a request on its own initiative.

Step 1: the user equipment transmits to the functional control module service request to the backup media to install at least one channel content delivery.

Stage 2: between the functional module management services (which corresponds to the module of P-CSCF in the base IMS if the IMS system is used in the system NGN), and the control subsystem resource and admission is resource reservation according to the information contained in the request to the backup media.

Phase 3: functional module management services (or module P-CSCF) initiates a request to the backup media to establish at least one channel for delivering content and forwards the request to the functional control module IPTV service.

Step 4: functioning of the social management module IPTV service sends a response to the functional module management services relative to the backup media to install channels for content delivery.

Step 5: between the functional module management services (or module P-CSCF) and a control subsystem resource and admission is updated resource reservation, which practically can be performed or not performed according to specific requirements.

Step 6: the functional module management services (or module P-CSCF) sends subscriber equipment response to the backup media to install channels for content delivery.

Method 2: the request is initiated by the functional control module IPTV service.

Stage 1: functional management module IPTV service initiates the request for the reservation of media to establish at least one channel for delivering content and forwards the request to the functional module management services (which corresponds to the module of P-CSCF in the core IMS in the case of IMS).

Stage 2: between the functional module management services (or module P-CSCF) and a control subsystem resource and admission of perform resource reservation.

Phase 3: functional module management services initiates the request for the reservation of media to establish at least one channel for delivering content and forwards the request to the subscriber equipment.

Stage 4: the subscriber equipment function returns the tional control module services (or module P-CSCF) response to the backup media to establish channels for content delivery.

Step 5: update the resource reservation between the functional module management services (or module P-CSCF) and a control subsystem resource and admission.

Step 6: the functional module management services (or module P-CSCF) returns the functional control module IPTV service response to the backup media to establish channels for content delivery.

After deciding whether to reproduce the information, the recommended functional control module IPTV service, the subscriber equipment in response to a request to initiate a communication session sends to the functional control module IPTV service via functional module management services the result of his decision. Functional module management services decides agrees whether the subscriber equipment to reproduce the above information corresponding to the identifying information contained in the response message confirming the consent of the subscriber equipment to reproduce the above information. If a positive decision function module management service interacts with the control subsystem resource and admission, provides the above-mentioned reserved resources and directs the above CTE is the can message to the functional control module IPTV service. In case of a negative decision function module management service interacts with the control subsystem resource and admission, free above, reserved funds and sends a response message to the functional control module IPTV service; and after receiving the response message, the function module service management IPTV comes to the conclusion that the subscriber equipment refuses to reproduce the above information in accordance with the response message, the thread terminates, and the subsequent processing is not executed.

Thus, as described above, according to this variant implementation of the present invention can be achieved proactive dissemination network side information about the broadcast program to the user equipment, through which extends a content service offered by the operators.

For a more detailed description of this option is the implementation of the above method as an example will be considered in situations when the recommended information is a service of the direct broadcast.

Figure 5 shows the detailed functional diagram of the implementation of this alternative implementation of the present invention. As shown in Figure 5, the proposed method under this Varian is the implementation includes the following steps.

Step S502: the functional control module IPTV service actively initiates the communication session to initialize services direct broadcast, representing a package of direct broadcast (full audio - and video-based, consisting of content, metadata and so on), and the request for initialization of a communication session is routed to the functional module management services to obtain services direct broadcast.

As mentioned above, the request for initialization contains query parameters, which, in particular, can include information such as identifying information about distribution, information describing the content of the programs live broadcast of the recommended channel, duration, etc. in Addition, the parameters of the request may also contain a list of identifying information related to a unique identification of the user equipment, which can be specified identifying at least one subscriber equipment.

In addition, to identify services direct broadcast offered the subscriber equipment, the identifier of each service direct broadcast should be included in the request for initialization.

Step S504: the functional module management services shall send the above request for initialization of the subscriber equipment corresponding to each of the ID in the list of identifying information, which is contained in the specified request initialization.

Step S506: define, agree whether the subscriber equipment to stream services live broadcast of the recommended channel, in case of positive result of the continued implementation of the proposed method with the transition to step S508, otherwise the method proceeds to step S510.

Step S508: perform the exchange of signals between the functional control module IPTV service and subscriber equipment for establishing at least one channel for delivering content, and channel for delivery of content to perform services direct broadcast, and the main objective of this exchange signals is to reserve the resource and the allocation of bandwidth to ensure proper QoS live broadcast of the recommended channel, etc.

Step S510: the user equipment sends to the functional control module service response message about initializing a communication session, which contains supporting information consent of the subscriber's equipment to play live broadcast of the specified recommended channel, and if at the step S506 is determined that the user equipment refuses to play directly stream live broadcast of the recommended channel, then that is S514, otherwise, at step S512.

Step 512: the functional module management services (which corresponds to the modulus P-CSCF basic IMS in the case of IMS) and control subsystem resource and admission provide and provide all the information about the resources reserved at step 508, and activate the package of services direct broadcast communication network to the perimeter network to the subscriber's equipment to connect to the stream of multicast.

Step S514: the functional module management services directs the functional control module IPTV service response message about initializing a communication session is transferred to the subscriber equipment, and if the identifying information contained in the response message indicates that the user equipment refuses to play a direct broadcast of the above channel, the flow ends; otherwise, perform step S516.

Step S516: the user equipment communicates with the transport functional module in the transport network connects to the channel group broadcast and begins to accept the flow of multicast and manages content and stream a live broadcast of the delivered content.

In step S508, if the receiving network parameters subscribers the sky equipment is used to initialize a communication session, i.e. this stage is triggered by a functional module, select services, then step S508 according to this variant implementation executes after the user equipment initiates the service request live broadcast. Figure 6 illustrates in greater detail the implementation of step S508 for this case. As shown in Fig.6, the process, in particular, contains the following steps.

Step S602: the user equipment transmits to the functional control module service request to the backup media to establish at least one channel for delivering content.

Step S604: perform resource reservation between the functional module management services (or module P-CSCF) and a control subsystem resource and admission according to the information contained in the request to the backup media.

Step S606: the functional module management services (or module P-CSCF) initiates a request to the backup media to establish at least one channel for delivering content and forwards the request to the functional control module IPTV service.

Step S608: the functional control module IPTV service returns the functional module management services response to the backup media, providing channels for content delivery.

Step S610: update the redundancy R is Sursa between the functional module management services (or module P-CSCF) and a control subsystem resource and admission. Practically, this step can run or not run depending on your specific requirements.

Step S612: the functional module management services (or module P-CSCF) returns the subscriber equipment response about the media, providing channels for content delivery.

If the receiving network parameters of subscriber equipment occurs during the initialization of the communication session, step S508 perform the following way, as shown in detail 7.

Step S702: the functional control module IPTV service initiates the request for the reservation of media to establish at least one channel for delivering content and forwards the request to the functional module management services (which corresponds to the module of P-CSCF in the core IMS in the case of IMS).

Step S704: perform resource reservation between the functional module management services (or module P-CSCF) and a control subsystem resource and admission.

Step S706: the functional module management services initiates the request for the reservation of media to establish at least one channel for delivering content and forwards the request to the subscriber equipment.

Step S708: the user equipment returns to the functional module management services (or module P-CSCF) response Rel is relatively carriers, providing channels for content delivery.

Step S710: update the resource reservation between the functional module management services (or module P-CSCF) and a control subsystem resource and admission.

Step S712: the functional module management services (or module P-CSCF) returns the functional control module IPTV service response about the media, providing channels for content delivery.
