Apparatus and method for controlling operation mode in a wireless terminal
First Claim
1. A method for performing a predetermined operation by switching between a sleep state and an active state by a communication processor (CP) in a wireless terminal having an application processor (AP) and the CP, the method comprising:
- recording, in an internal memory of the CP, a control program configured for the active state of an internal mode, wherein the internal memory of the CP is dedicated to the CP;
waking up from the sleep state to the active state of the internal mode at every predetermined interval;
performing, by the CP, an operation required in the active state of the internal mode by executing the recorded control program in the internal memory of the CP; and
determining whether to switch from the internal mode to a normal mode,wherein the CP operates based on the internal memory of the CP without accessing an external memory during the internal mode, and the CP operates based on the external memory during the normal mode, andwherein the recorded control program is a complete control module or a part of the complete control module that is recorded for the operation required in the active state in the external memory.

Abstract
An apparatus and a method for controlling a Discontinuous Reception (DRX) mode in which a Communication Processor (CP) performs a predetermined operation by switching between a sleep state and an active state in a wireless terminal having an Application Processor (AP) and the CP are provided. The method includes recording a control program configured for the active state in an internal memory of the CP, waking up from the sleep state to the active state at every predetermined interval, and performing an operation required in the active state by executing the control program recorded in the internal memory via the CP, wherein the control program is a complete control module or a part of the complete control module.

8. An apparatus for performing a predetermined operation by switching between a sleep state and an active state in a wireless terminal having an application processor (AP) and a communication processor (CP), the apparatus comprising:
-
an internal memory of the CP that is dedicated to the CP, configured to record a control program configured for the active state of an internal mode, wherein the CP is configured to; wake up from the sleep state to the active state of the internal mode at every predetermined interval, and perform an operation required in the active state of the internal mode by executing the recorded control program in the internal memory and to determine whether to switch from the internal mode to a normal mode, wherein the CP operates based on the internal memory of the CP without accessing an external memory during the internal mode, and the CP operates based on the external memory during the normal mode, and wherein the recorded control program is a complete control module or a part of the complete control module that is recorded for the operation required in the active state in the external memory. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A wireless terminal, the terminal comprising:
-
a communication processor having an internal memory dedicated to the communication processor, and configured to perform communication functions by executing a control program; and an application processor having an external memory, wherein the communication processor operates based on the internal memory without accessing the external memory during an internal mode, and the communication processor operates based on the external memory during a normal mode, wherein the control program is a complete control module or a part of the complete control module that is recorded for the communication functions in the external memory, wherein, if a size of the recorded control program exceeds a size of the internal memory, a paging module of the control module is stored in the internal memory during a discontinuous reception mode, and wherein the paging module causes the wireless terminal to monitor a paging channel in the discontinuous reception mode. - View Dependent Claims (17, 18)
