Problems solved by technology

This improvement also didn't gain much consensus in the IETF because it introduced additional dependencies and complexities in the MIPv6 protocol
[0011] Therefore, prior art methods currently do not provide a simple, efficient and practical solution to ordering PBUs when a mobile device roams between different MAGs connected to the LMA

Embodiment Construction

[0024] The invention relates to a method for managing the movement of a mobile device MS, such as a mobile terminal or mobile station, in a network using the proxy MIPv6 protocol as defined by the IETF.

[0025] In particular, the proxy MIPv6 protocol includes two logical functions of MAG (Mobile Access Gateway) and LMA (Local Mobility Anchor). The MAG function is responsible for handling the network access of the mobile device MS and performs MIPv6 signaling (binding protocol) on behalf of the device to the LMA function (acting as an extended Home Agent HA).

[0026] When a mobile device MS roams between different MAGs connected to the same LMA, the mobile device performs a registration to the access network of the MAG. Next, the MAG issues a PBU (Proxy Binding Update) to bind the mobile device MS with the LMA

[0027] The method involves a relative time synchronization procedure between the LMA and all MAGs connected to it. To this end, LMA time is initiated and maintained...

Abstract

Method for managing mobility of a mobile device (MS) within a network using a proxy MlPv6 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the LMA or if the timestamp is newer than the one received from the MAG currently binding the mobile device (MS); an out of date PBU-Ack if the timestamp is not newer than the one received from the MAG currently binding the mobile device (MS).

Description

technical field [0001] The present invention relates to a method of using the proxy MIPv6 protocol to manage the movement of mobile devices in the network, which is used to proxy the logical functions of the mobile access gateway MAG and the local mobility anchor LMA of the MIPv6 protocol. The present invention also relates to the use of the proxy MIPv6 A network that includes the above logical functions. Background technique [0002] The Mobile IPv6 protocol (Internet Protocol Version 6) - also known as MIPv6 - is defined by the IETF (see D. Johnson, C. Perkins, J. Arkko, 'Mobility Support in IPv6', IETF RFC 3775, June 2004, Available at http: / / www.ietf.org). The protocol is an IP-based mobility protocol that enables mobile devices (also known as mobile nodes or mobile stations) to move between subnets in a manner that is transparent to higher layers and applications, that is, without interrupting higher layer connections . Thus, mobile devices remain reachable as they m...
