How to manage the mobility of the mobile device in a network that uses a proxy MIPv6 protocol

摘要

A MAG logical function and the LMA method for managing the mobility of the logic functions and a mobile device within a network using a proxy MIPv6 protocol comprising (MS), MAG is bound mobile device (MS) to the LMA issue a proxy binding update (PBU) to, the LMA time is initialized, is maintained within the the LMA, the method, the LMA and the relative time synchronization procedure between the all of it to the connected MAG wherein the procedure, each MAG will stipulates sending a PBU with specific semantics to request the LMA time, PBU acknowledgment sent by the LMA (PBU-Ack) includes such a LMA time , wherein are maintained within each LMA time further MAG, the method further all MAG is, in each PBU sent, comprises a binding procedure of inserting a timestamp including the current maintained the LMA time. When receiving the PBU to LMA time-stamped from the MAG, LMA is - If there is no other MAG that are currently bound move device (MS) to the LMA, or if the time stamp is newer than the time stamp that has been receiving mobile device (MS) from the MAG currently binding success PBU the -Ack, - Time stamp, if not newer than the time stamp that has been receiving mobile device (MS) from the MAG that are currently bound to send the expiration PBU-Ack.
