The present invention relates to a method and apparatus for processing cell broadcast messages of a mobile communication terminal having a plurality of communication processors and application processors. The processor determines whether the cell broadcast message is identical and filters the cell broadcast message, and accordingly, the application processor does not process the repeatedly transmitted cell broadcast message, thereby saving the battery power consumption of the mobile communication terminal. And to an apparatus.

Recently, with the development of mobile communication technology, transmission of text messages, still image messages, video messages, cell broadcast messages (CB messages) and the like using a mobile communication network is increasing. In particular, the cell broadcast message is a message transmitted simultaneously to all mobile communication terminals registered in the same cell of a communication network by a cell broadcast service (CBS), unlike a general short text service (SMS). One-way message with no acknowledgment.

In the cell broadcast message, the same contents are periodically sent, and each mobile communication terminal may set a specific reception channel to receive the required cell broadcast message. The cell broadcast message includes arbitrary channel information and language information, and the channel information is information on a channel for providing a cell broadcast service, and includes a message transmission method, a message transmission time, a channel name, and the like. Information on the content of the cell broadcast message includes a text data format of the cell broadcast message, information on the text content, and the like. Therefore, if channel information and language information of the cell broadcast message are checked and analyzed, it is possible to determine whether the cell broadcast message is the same.

The cell broadcast service is a service that simultaneously transmits data to all mobile communication terminals in the same cell through a mobile communication base station, and the personal information arrival rate (90%) is lower than that of a short message service (SMS). Low traffic and low cost of paging channel, and especially low cost of sending, especially multimedia based delivery (LOD) and location based service such as video on demand (VOD), Emergency disaster alerts can be provided.

However, since a cell broadcast message including the same channel information and language information is often transmitted repeatedly at a predetermined period, there is a problem that battery power of the mobile communication terminal is wasted for processing the cell broadcast message of the same content. 1 is a diagram illustrating a cell broadcast message transmission of a mobile communication terminal having a conventional communication processor and an application processor. Referring to FIG. 1, the reason why battery power of a mobile communication terminal is wasted when receiving a cell broadcast message is as follows.
