Problems solved by technology
[0013] Therefore, in most cases, users cannot receive emergency information immediately, which will bring two adverse consequences:
[0014] Users cannot get information immediately and respond quickly;
[0015] The transmission system cannot confirm whether the user has received the emergency information, and can only repeatedly send the information for a long time to increase the possibility of the user receiving it, which will occupy a large amount of bandwidth resources

Embodiment Construction
[0034] The embodiment will be further described in detail below in conjunction with the accompanying drawings.
[0035] The implementation of the present invention requires cooperation between the system and the terminal. After the broadcast receiving function of the terminal is turned off, not all circuits are turned off. The control module should be in the standby state, and the rest of the functional modules can be in the off state, and some functional modules can also be in the standby state. This part of the circuit will listen to whether there is an emergency message prompt in the broadcast information, so as to make a corresponding response.
[0036] figure 1 It is a schematic diagram of the structure of the mobile multimedia broadcast emergency information receiving system of the present invention, mainly including the broadcast receiving module 4 in the transmitting system 1 and the receiving terminal, wherein the broadcast receiving module 4 includes a tuner 5, a dem...

A method is provided for ensuring a mobile multimedia broadcast terminal to instantly receive system information. The method comprises the following steps: (1) allowing a control module of a terminal for stopping broadcast reception function, a tuner, a demodulation / decoding module and a resolution module to be in standby state, to monitor whether the broadcast channel has an emergence message hint; (2) sending the emergence message hint by a multimedia broadcast transmission side, and sending an emergence message; (3) after the terminal receives the emergence message hint, activating the functional module in off state by a control module to receive the emergence message; (4) presetting a mode for handling the emergence message at the terminal, and after receiving the emergence message, treating the emergence message at the terminal in the preset mode; and (5) after the terminal completes the treatment of the current emergence message, closing other activated reception circuit modules.
Description
technical field [0001] The invention relates to the field of mobile multimedia broadcasting, in particular to a method for enabling terminals to receive system information immediately in mobile multimedia broadcasting. Background technique [0002] In mobile multimedia broadcasting, in some cases, the receiving terminal needs to be able to receive the emergency information sent by the system immediately and present it to the user, such as: [0003] Warning information, such as: earthquake information, fire information, flood information, typhoon information, etc. [0004] User-related information: such as arrears information, reminder fee information, stored-value card recharge success information, etc. [0005] System-related information: such as the update information of the electronic business guide, etc. [0006] If the receiving terminal cannot be guaranteed to receive the information immediately, the system needs to repeatedly send the information, which will occupy ...
