Method and system supporting movement of mobile network

Abstract

The invention discloses a method for supporting the motion of a mobile network, which is used in a local mobility management region including a local access anchor LMA, a plurality of mobility access gateways MAG and a mobile network with a mobile router MR; when the MR moves within the region and is switched to a new MAG, the new MAG can obtain MR routing items from the LMA that stores the MR routing items, so as to achieve the motion of the mobile network wholly supported by network side support in the local mobility management region. A system for supporting motion of the mobile network isdisclosed either. The motion of the mobile network supported by the network side can be realized in the local mobility management region by using the system.

Description

A method and system for supporting mobile network mobility technical field The invention relates to mobile network technology, in particular to a method and system for supporting mobile network mobility in a local mobility management domain. Background technique The biggest difference between Network-Based Local Mobility Management (NETLMM) and global mobility management is that the mobile node (MN), as a terminal network device, does not change its IP address during the movement within the local mobility management domain, so that it does not Processes such as obtaining a new IP address, duplicate address detection (DAD), and registering a new care-of address with the home agent (HA) are required, which reduces handover delay and air interface signaling; in addition, since the MN does not change the IP address, the The privacy of the MN location is improved over global mobility management. In the local mobility management domain, the terminal network equipment includes ...

AI Technical Summary

Problems solved by technology

From the perspective of the management of the mobile network in the existing local mobility management domain mentioned above, when the MR moves within the domain, although the CoA between the MR and the MAG remains unchanged, the MR still needs to detect the mobility of the network and report to the MR_HA registration, no real support for mobile networks in the local mobility management domain

In addition, the establishment of a bidirectional tunnel between MR and MR_HA makes the path for transmitting packets longer, especially when the distance between MR and HA is relatively long, which increases the round-trip time of packets
