Abstract
During allocation of time slots of a UMTS frame to a terminal, the UMTS network provides a continuous gap having a duration at least equal to 5 ms in a UMTS frame to enable the receiver of the terminal to measure the power of any GSM signals received and to prepare for possible handover by pre-synchronizing to an adjoining GSM cell.
