Description

Method and device for processing emergency broadcast message

Technical field

The present invention relates to the field of mobile multimedia broadcasting, and in particular, to a method and apparatus for processing an emergency broadcast message.

Background technique

In recent years, digital mobile multimedia broadcasting technologies and standards have developed rapidly, such as DVB-H (Digital Video Broadcast Handheld) in Europe, MediaFLO (Media Forward Link Only) in the United States, based on Mobile cellular BCMCS (Broadcast and Multicast Services), etc., Data Mobile Multimedia Broadcasting Network provides many end-users with service content such as advertisements, weather forecasts, news, sports programs, variety shows, multimedia radio dramas, movies, etc. The user can select the service program provided by the mobile multimedia broadcast according to his or her preference. Emergency broadcasting is a way to use the broadcast communication system to notify the public of an emergency. Emergency broadcasts provide a rapid response to emergencies such as natural disasters, accident disasters, public health and social security that cause or can cause major casualties, property damage, ecological damage and serious social hazards that endanger public safety. Quick notification method. As the state attaches importance to various emergencies and various public emergency plans, it is necessary to provide emergency broadcasting services as a broadcasting technology with a large number of online users. A mobile terminal having an emergency broadcast message can receive an emergency broadcast message from an emergency broadcast system.

1 is a frame structure diagram of a mobile multimedia broadcast channel. As shown in FIG. 1, a plurality of multiplexed frames constitute a broadcast channel frame, and the multiplexed frame is composed of a multiplexed frame header, a multiplexed payload, and a padding portion.

For example, it is determined that 1 second is the multiplexing period, divided into 40 time periods (time slots), and the multiplexing unit is 25 ms. The logical multiplexing frame and time slot mapping is determined by the system configuration.

A multiplex frame corresponds to a control or service logical channel, and each multiplex frame is assigned a multiplex frame identifier MF_ID, and the MF ID ranges from 0 to 39, and the maximum is 39. The multiplex frame of MF_ID=0 is mapped to the control logical channel, and is used to transmit system control information, and the multiplex frame identifier MF-ID is not zero. The frame is mapped to the service logical channel for transmitting service information.

As shown in FIG. 2, a multiplex frame with a multiplex frame identifier of zero is used to carry control information, and a multiplex frame payload in the multiplex frame includes a plurality of control information tables, and each multiplex subframe includes one control information. Table composition. In the existing mobile multimedia broadcast specification, the emergency broadcast service is transmitted in a control information table whose table number is 0x10 in the control information multiplexing frame.

As shown in Figure 3, in order to adapt to the CMMB (China Mobile Multimedia Broadcasting) technology system, the emergency broadcast message is encapsulated into an MSF (Multiplex SubFrame) that can be transmitted in the CMMB broadcast network. format.

In the prior art, after the user terminal receives the emergency broadcast multiplex subframe, the emergency broadcast message is parsed and stored in the memory, and the emergency broadcast message is displayed by opening a new window; when the user terminal receives the new one again The emergency broadcast message will overwrite the original emergency broadcast message in the memory, so that the user can not see the emergency broadcast message received before.

The existing technology has the following disadvantages:

1. Unable to view all emergency broadcast messages;

2. It is not possible to forward, delete, etc. all received emergency broadcast messages.

3. The emergency broadcast message needs to be managed separately, including: display, save, etc., and the terminal memory consumption is large.

Therefore, it is necessary to provide a reasonable and convenient way to manage received emergency broadcast messages. Summary of the invention

The technical problem to be solved by the present invention is to provide a method and a device for processing an emergency broadcast message, which overcomes the problem of inconvenient operation and management of emergency broadcast messages in the prior art.

In order to solve the above technical problem, the present invention provides a method for processing an emergency broadcast message, in which the terminal converts the received emergency broadcast message into data in a short message format, and manages it according to the method of managing the short message.

Further, the terminal converts the received emergency broadcast message into data in a short message format, specifically: the terminal parses the received emergency broadcast multiplex subframe, extracts the emergency broadcast text data, and converts the text data into a short Data in message format. Further, the terminal receives the emergency broadcast multiplex subframe from the emergency broadcast receiving chip. Further, after the terminal converts the received emergency broadcast message into data in a short message format, the terminal stores the emergency broadcast message converted into the short message format into the short message inbox.

Further, after converting the received emergency broadcast message into data in a short message format, the terminal notifies and displays the data to the terminal user.

Further, after the terminal converts the received emergency broadcast message into data in a short message format, the terminal user forwards the emergency broadcast message converted to the short message format by the terminal.

Further, after the terminal converts the received emergency broadcast message into data in a short message format, the terminal user performs a delete operation on the emergency broadcast message converted into a short message format by the terminal.

Further, the method includes the following steps:

(1) The terminal receives an emergency broadcast multiplex subframe from the emergency broadcast receiving chip;

(2) parsing the emergency broadcast multiplex subframe to extract text data;

(3) converting the text data into data in a short message format;

(4) transmitting the data in the short message format to the short message application module of the terminal;

(5) the short message application module stores the emergency broadcast message in the short message format into the short message inbox, and notifies the terminal user to receive the emergency broadcast message;

(6) The short message application module displays the emergency broadcast message to the end user.

In order to solve the above technical problem, the present invention further provides an apparatus for processing an emergency broadcast message, including: a receiving unit, a parsing unit, a converting unit, and a short message processing unit, where:

The receiving unit is configured to receive an emergency broadcast multiplex subframe and output the signal to the parsing unit, where the parsing unit is configured to parse an emergency broadcast multiplex subframe, extract emergency broadcast text data, and output the Conversion unit

The converting unit is configured to convert the emergency broadcast text data into data in a short message format, and output the data to the short message processing unit;

The short message processing unit is configured to notify the terminal user that the emergency broadcast message is received, and An urgent broadcast message is displayed to the end user.

Further, the short message processing unit is further configured to store the emergency broadcast message converted into the short message format into the short message inbox.

The invention converts the emergency broadcast message into a short message, and can save all the received emergency broadcast messages in the short message inbox in time for convenient viewing, and can perform operations such as forwarding and deleting, and manage the emergency like managing short messages. Broadcast messages save a separate management space for emergency broadcast messages, saving memory consumption for the terminal.
