Abstract
A method of handover between two cells of a TDMA cellular mobile radio network, wherein, after a mobile receives a handover command (HANDOVER CMD) from its base station, the mobile transmits a message (SABM) containing connection set-up information or wanted data to a new base station according to a timing advance. The handover command tells the mobile not to transmit access bursts to the new base station, thus avoiding speech interruption. The timing advance is determined by the mobile or communicated to the mobile in the handover command.
