Fast synchronised transparent handover method and system
First Claim
1. A method for performing a handover in a wireless communications system, the system comprising at least one mobile terminal, a plurality of base stations,at least one central entity managing the plurality of base stations, whereby the method comprises the steps of:
- the mobile terminal transmits a handover request message in a pre-assigned slot, requesting a new point of attachment;
the plurality of base stations upon receiving the handover request message determine which one of the plurality of base stations is to become the new point of attachment;
a base station upon completion of the determination on becoming the new point of attachment transmitting a handover response message to the mobile terminal;
the mobile terminal upon reception of the handover response message changing its point of attachment.
