Problems solved by technology

[0004] A DSP that handles multimedia functions can be installed inside the modem, but compared to adding a dedicated DSP, the performance is lower, and when the modem processes more data, the load on the modem itself is heavier
In addition, with existing technology, even if two modems are installed, there is the same problem as using a single modem, the problem of needing to install a DSP separately or processing all data in one modem

Embodiment Construction

[0010] In the following, the above objects, features and advantages will be further described through the accompanying drawings, and the embodiments applicable to the present invention will be described in detail in combination with the accompanying drawings.

[0011] In the present invention, in a DBDM (Dual Band Dual Mode) terminal using a dual-mode modem, the multi-media function is realized by utilizing the dual-mode modem. Instead of using a separate DSP (Digital Signal Processor), two processors are used in a master / auxiliary (Master / Slave) manner to improve data processing efficiency.

[0012] That is, when a dual-mode modem is used in a mobile communication terminal using DBDM technology, only one modem supports all functions in synchronous mode or asynchronous mode, that is, one of the modems is hardly used, so it can be unused The modem is used to perform functions such as multimedia codec or multitasking.

[0013] For example, while one modem is activated and opera...

Abstract

The invention relates to a method of treating multi-tasking, especially a method of treating multi-tasking in the mobile communication terminal having multiple modem comprising: activating the first modem for realizing the communication with external; the first modem receiving the request signal of the multi-tasking; sending the task information except the executing communication from the first modem to the second modem; the first modem receiving the executable or not information of the said task. When the mobile communication terminal having multiple modems executes the multi-tasking, the invention can execute other modem except the modem which is executing the communication task so as to improve the performance of multi-tasking.

Description

technical field [0001] The present invention relates to a method for performing multiple tasks using a mobile communication terminal having multiple modems, and more particularly to a method for performing multiple tasks more efficiently by using one modem as a master modem and the other modems as slave modems. multitasking approach. Background technique [0002] In the prior art, only one modem is used for one mobile communication terminal. And recently, in order to realize dual frequency dual mode (DBDM), a mobile communication terminal having two modems has been developed. For example, in order to apply to both synchronous systems (such as CDMA 1x) and asynchronous systems (such as WCDMA), the technology of installing two modems. [0003] In addition, with the demand for multi-tasking functions such as shooting movies, photo editing, playing MP3 (MPEG layer 3) and other multimedia functions, and taking photos while listening to MP3, mobile communication terminals have a...
