Mobile television broadcasting control system and broadcasting network and method

Abstract

The invention discloses a mobile TV broadcast control system, which includes a business center, a business key management module, a subscription relationship management module and a guide service function module. The guide service function module is used to encrypt the service by using the network side user key Key; the guidance service function module is used to connect with HLR or HSS in the mobile communication network, generate network-side user key according to the user authentication data obtained from HLR or HSS, and send it to the service center. Also disclosed are a mobile TV broadcast network based on the mobile TV broadcast control system and a mobile TV program broadcast method based on the mobile TV broadcast control system. Through the present invention, the directional transmission of the key is realized, avoiding the risk of unauthorized terminals cracking the group sending key and pirating mobile terminal broadcast TV network programs; avoiding the high occupancy rate of network resources; realizing mobile operators and Broadcasting operators jointly carry out business operations.

Description

technical field [0001] The present invention relates to a mobile TV broadcast control system, a broadcast network and a broadcast method based on the control system, in particular to a mobile TV broadcast control system combining a mobile communication network and a broadcast TV network. Based on the mobile TV broadcast The broadcasting network of the control system and the program broadcasting method through the mobile TV broadcasting control system belong to the technical field of mobile communication. Background technique [0002] With the development of communication technology, users are no longer satisfied with watching TV programs at fixed terminals, but hope to watch their favorite programs at any time while freely moving. [0003] At present, the development of broadcasting technology has realized the broadcasting of TV programs to mobile terminals through the broadcasting TV network, so that users can watch TV programs whether they are indoors or outdoors, local or...

AI Technical Summary

Problems solved by technology

[0005] First, the broadcasting of TV programs can be encrypted, but the key can only be sent in groups and cannot be sent in a targeted manner; therefore, even if only one user chooses to watch a certain program, the broadcasting network must Issuing keys to all user terminals in the coverage area causes unnecessary waste of system resources and network bandwidth, and also increases the probability of key cracking, which is not conducive to ensuring the business security of operators and is not conducive to the verification of user qualifications. valid certification;

[0006] Second, when a TV program is sent by broadcast, the broadcast TV network has no way of knowing whether the terminal has received the TV program. In order to ensure successful reception, it can only be sent repeatedly, which brings a huge load and waste to the system;

[0007] Third, sending TV programs through broadcasting is a one-way transmission, and users cannot give feedback, so they can only receive passively, but cannot actively participate; therefore, it is not conducive to users to obtain a good experience, nor is it conducive to the development of value-added services

[0010] First, the bandwidth provided by the mobile communication network is insufficient, so the user's viewing effect cannot be guaranteed;

[0011] Second, the network bandwidth and server resources of SP / CP are limited by the number of users. Therefore, if there are many users watching at the same time or encountering network congestion, the viewing effect of users cannot be guaranteed
