Problems solved by technology
[0005] However, such a mobile communication terminal has a disadvantage in that battery power consumption is high because two antennas and two radio frequency receivers are used together.
Also, in order to perform various controls related to the two RF receivers, a large load is placed on the hardware and software of the terminal

Embodiment Construction
[0013] Several embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same symbols indicate the same or similar elements. Also, detailed descriptions of known functions and structural configurations are omitted for conciseness.
[0014] FIG. 1 is a block diagram of an example of components of a mobile communication terminal according to an embodiment of the present invention. The mobile communication terminal uses: two antennas and two radio frequency (RF) receivers utilizing a space diversity technique to provide a high data rate (HDR) service. As shown in Figure 1, the mobile communication terminal comprises two antennas labeled ANT1 and ANT2. The first antenna ANT1 is installed on the body of the mobile communication terminal. Preferably, the first antenna ANT1 is a non-directional retractable antenna configured to enable two-way communication through the terminal and facilitate handling of t...

A system and method for controlling the operation of a mobile communication terminal capable of providing a high-speed data rate (HDR) service. If the second antenna is connected to the second RF module, a first query message is sent to a user of the terminal to confirm whether the connection of the second antenna has been made for the HDR service. If an external terminal is connected to the mobile communication terminal under the above condition, a second query message is sent to the external terminal to confirm whether the connection of the external terminal has been made for the HDR service. If there is a response from at least one of the external terminal and terminal user to the first and second query messages, battery power is supplied to both the first and second RF modules and signal processes associated with the first and second RF modules are performed. If there is no response to the first and second query messages, a determination is made as to whether a current mode of the mobile communication terminal is a traffic mode for the HDR service. If the current terminal mode is the traffic mode for the HDR service, the battery power is supplied to both the first and second RF modules, and the signal processes associated with the first and second RF modules are performed. If the current terminal mode is not the traffic mode for the HDR service, the supply of the battery power is blocked to the second RF module, and the signal process associated with the first RF module is performed.
Description
technical field [0001] The present invention relates to mobile communication terminals, and in particular to such a system and method for controlling mobile communication terminals capable of providing high data rate services; the present invention also relates to such a system and method for controlling mobile communication terminals capable of providing high data rate services A mobile communication terminal while reducing the battery power consumption of various controls related to the two radio frequency receivers in the terminal and the load on the hardware and software of the terminal. Background technique [0002] Recently, some mobile communication companies are preparing to implement a high data rate service (HDR) capable of improving the quality of very high speed wireless Internet service when connected with Code Division Multiple Access (CDMA) 2000-1x. HDR services do not support separate voice services, but have good data transmission capabilities that exceed th...
