METHOD FOR HANDOVER BETWEEN DIFFERENT TYPE MMMB SYSTEMS

摘要

Disclosed is a method for controlling activation/deactivation of two kinds of operation modes of an MMMB mobile terminal during handover between different types of systems. To control the activation/deactivation, a system controller instructs the mobile terminal to activate/deactivate the operation modes or provides activation/deactivation conditions to the mobile terminal. In particular, when the mobile terminal in communication is situated in a border cell neighboring a target system, the mobile terminal activates target system-related modules and then performs handover into the target system according to predetermined conditions after the passage of a predetermined time period. Such a handover method minimizes time required for performing handover, prevents deterioration of call quality during the handover, and saves power consumption of the mobile terminal.
