Title:
METHOD AND ARRANGEMENT FOR AVOIDING LOSS OF ERROR-CRITICAL NON-REAL TIME DATA DURING CERTAIN HANDOVERS
Document Type and Number:
WIPO Patent Application WO2000032001
Kind Code:
A3
Abstract:
A method is disclosed for a mobile station for performing a handover from a first network connection to a second network connection. A mobile telecommunication system provides for non-real time telecommunication connections over a radio interface between mobile stations and the fixed parts of the mobile telecommunication system. At least one active non-real time telecommunication connection between a mobile station and the fixed parts of the mobile telecommunication system is suspended (704) before performing a handover (702') from the first network connection to the second network connection. After the new connection has been established the suspended non-real time telecommunication connection is resumed (705).
