Embodiment Construction

[0059] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0060] In order to solve the problem of low bandwidth efficiency and high power consumption at the receiving end caused by carousel broadcasting of EMM information in the prior art, the present invention proposes a method for dynamically scheduling and broadcasting EMM information, and dynamically determines the scheduling according to the scheduling strategy information, send the scheduling information to the receiving device, and when the network side sends the EMM information to the user, it will broadcast according to the dynamically determined scheduling information, and the receiving device will automatically start receiving the corresponding EMM information according to the scheduling information. By designing the scheduling strategy To achieve higher bandwidth efficiency and reduce receive power consumption.

Abstract

The invention discloses an entitlement management message scheduling system in mobile multimedia broadcasting and a scheduling method thereof, which is used for sending entitlement management messages to a terminal by a mobile multimedia broadcasting network side sending terminal; the network side sending terminal comprises a service management platform and a conditional access platform; according to a scheduling strategy, scheduling information is dynamically generated by the service management platform based on the obtained service entitlement messages, wireless resource use information andeffective time information; the scheduling information is sent to the conditional access platform and the terminal; according to the scheduling information, the conditional receiving platform sends the entitlement management messages to the terminal; the terminal receives the scheduling information and the entitlement management messages according to the scheduling information. According to the service and resource conditions, the invention is applied to dynamically receive the entitlement management messages and avoids the problems of low bandwidth efficiency and large power waste in the prior carousel mode.

Description

technical field [0001] The invention relates to the technical field of mobile multimedia broadcasting, in particular to a scheduling system and method for authorization management information in mobile multimedia broadcasting. Background technique [0002] In the conditional access system of mobile multimedia broadcasting, Entitlement Management Message (EMM) is a kind of information that authorizes a user to descramble a certain service, and the transmission of EMM is a key link. The EMM transmission mode in the prior art is mainly that the network side broadcasts the EMM information to the receiving terminal in carousel, and the receiving terminal regularly receives it according to the carousel cycle. The main problem with this carousel method is that because the carousel method uses a fixed period to broadcast EMM information, the network side and the terminal both send or receive EMM information according to a fixed period. When the number of users increases, the amount ...
