Abstract
Method for managing mobility of a mobile device (MS) within a network using a proxy MIPv6 protocol comprising MAG and LMA logical functions, wherein MAG issues a PBU to bind the mobile device (MS) with the LMA, a LMA-time being initialized and maintained within the LMA and the method comprising a relative time synchronization procedure between LMA and all of the MAG connected to it, said procedure providing that each MAG sends a PBU with specific semantics to request the LMA-time, the PBU acknowledgement (PBU-Ack) sent by the LMA including such LMA-time, said LMA-time being further maintained within each MAG, the method further comprising a binding procedure in which all of the MAG insert in each PBU sent a timestamp including the current maintained LMA-time. Upon receipt of a LMA-timestamped PBU from a MAG, the LMA sends a successful PBU-Ack if no other MAG currently binds the mobile device (MS) with the LMA or if the timestamp is newer than the one received from the MAG currently binding the mobile device (MS); an out of date PBU-Ack if the timestamp is not newer than the one received from the MAG currently binding the mobile device (MS).
