Problems solved by technology

In this way, for a large number of programs that users have not subscribed to, when the user chooses to play, the mobile terminal will initiate a request to the network side to apply for a service key. This request message will cause unnecessary traffic on the network and unnecessary traffic on the server side. Overhead and burden, resulting in a large amount of waste of network traffic, reducing network performance

Embodiment Construction

[0023] In the embodiment of the present invention, the subscription relationship information locally stored in the mobile terminal may be as shown in Table 1:

[0024] Table 1

[0025] name

[0026] The subscription relationship information shown in Table 1 can be pushed from the network side to the mobile terminal. The network side can extract part of the program ordering relationship information from the entity storing the program ordering relationship information, such as NAF (Network Application Function, network application function), such as information such as the channel ID and program ID ordered by the user, and send it to the mobile terminal. The terminal stores it in the local program order relationship table.

[0027] The mobile terminal can obtain program subscription relationship information in the following ways:

[0028] When the user opens the streaming media program client on the mobile terminal, the client sends an HTTP request, requesting to obt...

Abstract

The invention discloses a playing method and a mobile terminal for a streaming media program. The method comprises the process that a user requests to play the streaming media program through the mobile terminal, and also comprises the following steps: the mobile terminal judges whether a service key of the streaming media program exists in local part according to the request for playing the streaming media program; if a corresponding service key exists, the service key is adopted to decrypt and play the content of the streaming media program received from a network side; if the correspondingservice key does not exist, whether the streaming media program is ordered is judged according to information of program ordering relation locally stored by the mobile terminal, and the correspondingservice key is acquired from the network side and is adopted to decrypt and play the content of the streaming media program after the streaming media program is ordered. The adoption of the playing method and the mobile terminal can realize the reduction of network traffic and the improvement of network performance during the request for the streaming media program.

Description

technical field [0001] The invention relates to the communication field, in particular to a streaming media service playing method and a mobile terminal. Background technique [0002] The current network technology has been able to provide rich streaming media programs for mobile terminals, and users can choose streaming media programs to watch through mobile terminals. For example, the current mobile TV technology provides the possibility for users to watch TV programs through mobile terminals. [0003] The existing technical solution of mobile TV requires the user to obtain the service key of the program before watching the TV program on the mobile terminal. Usually, after the user subscribes to the program, the service key is sent to the mobile terminal by the network side and stored in the SIM (Subscriber Identity Module) card of the terminal, which is used to decrypt the received TV program content so that it can be accessed through the mobile terminal. play. There ar...
