Problems solved by technology

This method has the following defects: it depends on the accuracy of the time in the service guide. Generally speaking, the service guide is only for introduction and will not be very accurate. The error of each program will eventually lead to unacceptable deviation; the server sends the time information to The overhead of the terminal is large. For example, UTC, a commonly used time marking method in broadcasting networks, requires 40 bits; and this implementation method is not suitable for the case where the program time changes abnormally and does not match the time of the service guide.
This method has the following defects: high overhead: the server needs to record all the channels received by the terminal, such as the message overhead between the terminal and the server; delay: the server sends a push message to the terminal, and the terminal sends a request message after receiving it, and the server will update the send the content to the terminal
This method has the following defects: the terminal load is large: the time interval set by the timer cannot be too long, otherwise it is meaningless, but if the time is too short, the terminal load will be increased; the network overhead is large, a large number of check messages initiated by the terminal and the server Response increases network overhead; timing of endpoints is inaccurate
This method has the following defects: if the demand comes entirely from the mobile operator (for example, the interactive service is completely carried out by the mobile operator), it needs to negotiate with the broadcast operator, which will affect the flexibility of service development and the business model

Embodiment 1

[0043] Fig. 2 is a flow chart of Embodiment 1 of the method for triggering a terminal to initiate a request to a mobile server according to the present invention. When the program stream key message is pre-stored in the radio and television server, step 1 includes:

[0044] Step 011, the mobile server generates a program stream key message, and the program stream key message carries indication information indicating whether the terminal sends a request to the mobile server.

[0045] Step 012, the mobile server sends the program stream key message carrying the indication information to the radio and television server.

[0046] Step 013, replace the corresponding program stream key message pre-stored in the broadcasting server. For example, according to certain identifiers of the program stream key message, such as characteristic identifiers MSK_ID and MTK_ID, the corresponding program stream key message is replaced.

[0047] Assume that the planned time of the news broadcast i...

Embodiment 2

[0049] image 3 It is the flow chart of Embodiment 2 of the method for triggering the terminal to initiate a request to the mobile server in the present invention. When the program stream key message is pre-stored in the radio and television server, before step 1 includes:

[0050] Step 021, the mobile server sends a request to modify the indication information in the program stream key message or a request to add indication information in the program stream key message to the radio and television server. The program stream key message prestored in the broadcasting server may or may not contain indication information. When there is indication information in the program stream key message prestored in the radio and television server, the mobile server sends a request to modify the indication information in the program stream key message to the radio and television server; when there is no indication information in the program stream key message prestored in the radio and televi...

Embodiment 3

[0055] Figure 4 It is the flow chart of Embodiment 3 of the method for triggering the terminal to initiate a request to the mobile server in the present invention. When the program stream key message is pre-stored in the mobile server, before step 1 includes:

[0056] Step 031, the mobile server generates a program stream key message, and the program stream key message carries indication information indicating whether the terminal sends a request to the mobile server.

[0057] Step 032, replace the corresponding program stream key message prestored in the mobile server.

[0058] Step 033: Send the updated program stream key message to the broadcasting server.

[0059] Assuming that the planned time of the news broadcast is from 7:00 to 7:30, the mobile server uses the service key to encrypt the program stream key from 7:00 to 7:30, and pre-stores it in the mobile server; Notification, if an emergency event needs to be extended for 15 minutes in the news broadcast, the mobil...

Abstract

The invention relates to a method, a terminal and a radio server which are used for triggering the terminal to send requests to a mobile server. The method comprises the following steps: the radio server sends a program key stream message of a present program to the terminal, and the program key stream message carries indication information which indicates the terminal whether to send requests to the mobile server; and the terminal decides whether to send a request of obtaining updated content to the mobile server according to the indication information. The terminal comprises a receiving module, a requesting module and an identifying module which is respectively connected with the receiving module and the requesting module. The method, terminal and radio server of the invention send theindication information which is used for indicating the terminal whether to send requests to the mobile server to the terminal by utilizing the program key stream message, thus ensuring that the terminal sends the request of obtaining updated content to the mobile server according to program change situations or inclination of the mobile server and through the indication information.

Description

technical field [0001] The invention relates to the field of mobile television, in particular to a method for triggering a terminal to initiate a request to a mobile server, a terminal and a radio and television server. Background technique [0002] The mobile TV service refers to the service of receiving mobile video content with a terminal device in the form of a mobile phone. Mobile multimedia broadcasting is a transmission technical means to realize the mobile TV service. The mobile multimedia broadcasting service adopts the cooperative operation mode of the radio and television network side and the mobile network side, and adopts a hierarchical key system, specifically: the radio and television network side transmits the program stream key to the mobile network side, and the mobile TV service platform on the mobile network side uses The service key encrypts and encapsulates the program stream key, generates a program stream key message, and transmits it to the radio an...
