NEIGHBOR CELL MONITORING METHOD AND APPARATUS FOR DUAL-STANDBY MOBILE TERMINAL
First Claim
1. A neighbor cell monitoring method for a multi-standby mobile terminal, comprising:
- acquiring a neighbor cell information by a master communication unit performing neighbor cell monitoring;
performing cell tracking by both the master communication unit and a slave communication unit independently of each other;
detecting a cell change event by the master communication unit, and executing the cell change event by using the neighbor cell information acquired by the master communication unit; and
detecting the cell change event by the slave communication unit, and transmitting the neighbor cell information from the master communication unit to the slave communication unit, and executing the cell change event using the neighbor cell information transmitted to the slave communication unit.

Abstract
A neighbor cell monitoring method and apparatus for a dual-standby mobile terminal is provided to reduce unnecessary power consumption by controlling one of two communication units to operate in an idle state while the other performs neighbor cell monitoring. A neighbor cell monitoring method for multi-standby mobile terminal includes acquiring a neighbor'"'"'s cell information through neighbor cell monitoring by operation of a master unit; performing cell tracking by the master unit and a slave unit independently; executing, when a cell change event is detected by the master unit, the cell change event using the neighbor cell information by the master unit; and transmitting, when a cell change event is detected by the slave unit, from the neighbor cell information from the master unit to the slave unit and executing the cell change event using the neighbor cell information by the slave unit.
