Embodiment 1

[0191] Figure 7 It is the first embodiment of the mobility management method of the present invention. This embodiment is applicable to the MAPS-MN directly notifying the communication peer MAG-CN to update the HNP-tMAG-MN address mapping or HNP--new CoA mapping of the MN. Such as Figure 7 As shown, it specifically includes the following steps:

[0192] Step 701, triggered by the MAG-MN, see Embodiments 4-7 for specific triggers, the MAPS-MN decides to notify the MAG-CN to update the HNP-MAG-MN address mapping or HNP-CoA mapping of the MN. MAPS-MN obtains all CNs of the MN in the communication peer table, and at the same time queries the corresponding MAG-CN address or the CoA of the CN according to the CN, and then sends a CoA update message to the MAG-CN, which carries the HNP of the MN and the tMAG-MN address or CoA2 (ie mapping of HNP1 and tMAG-MN address or HNP1 and CoA2).

[0193] In this embodiment, in order for the MAPS-MN to query the address of the MAG-CN or the...

Embodiment 2

[0204] Figure 8 It is the second embodiment of the mobility management method of the present invention. This embodiment is applicable to the MAG-MAPS notifying the communication peer MAG-update HNP-tMAG-MN address mapping or HNP-new CoA mapping of the MN through the MAG-MAPS. Such as Figure 8 As shown, it specifically includes the following steps:

[0205] Step 801 is triggered by the MAG-MN. For specific triggering, refer to Embodiments 4-7. The MAPS-MN decides to notify the MAG-CN to update the HNP-MAG-MN address mapping or HNP-CoA mapping of the MN. MAPS-MN obtains all CNs of MNs in the communication peer table, and then sends a CoA update message to MAPS-CN, carrying the HNP of MN in the message, and, tMAG-MN address or CoA2 (that is, HNP1 and tMAG-MN address or HNP1 Mapping with CoA2), and at the same time need to carry CN's HNP or HoA or ID.

[0206] The purpose of the CoA update message is to send the address mapping between HNP1 and tMAG-MN or HNP1-CoA2 mapping t...

Embodiment 3

[0215] Figure 9 It is the third embodiment of the mobility management method of the present invention. This embodiment is suitable for the MAG to regularly update the MN-CN mapping table (ie, CNT) locally stored in the MAPS. Such as Figure 9 As shown, it specifically includes the following steps:

[0216] In step 901, after the MN accesses the PMIPv6 domain through the attachment process, it successfully registers with the MAPS-MN through the sMAG-MN. The MAPS-MN assigns a home network prefix (HNP1) to the MN, and establishes / updates a binding cache entry (BCE, Binding Cache Entry). The MAPS-MN caches the binding relationship between the MN and the sMAG-MN, which may specifically be expressed as the mapping relationship between HNP1 and CoA1, or the mapping relationship between HNP1 and the sMAG-MN address. The sMAG-MN establishes the HNP-CoA mapping relationship of the MN, that is, the HNP1-CoA1 mapping relationship.

[0217] Step 902, when the sMAG-MN receives the upli...

Abstract

The invention provides a mobile management method and a mobile management system. The mobile management method and the mobile management system comprises the steps of switching from a source mobile inserting access gateway at a mobile node (MN) to an object mobile inserting MN, directly sending node information direct to the MN and address information direct to the object mobile inserting access gateway from an mapping server of the MN or through a mapping server of a correspondent node (CN) to a mobile inserting access gateway of the CN of the MN. The invention further provides a mobile management system. The mobile management method and the mobile management system ensures that the receiving and sending of an internet protocol message between the MN and the CN is no waste of transmission path after the MAG is changed by the MN so that the mobile needs of the MN are satisfied.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobility management method and system. Background technique [0002] Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol, TCP / IP) did not consider the situation that the topological position of the terminal will change during the initial design, that is, the TCP / IP protocol itself does not support mobility. In the traditional TCP / IP network environment, IP provides the routing function for the Internet (Internet). It assigns logical addresses, that is, IP addresses, to all nodes (including hosts and routers), and each port of each host is assigned an IP address. An IP address includes a network prefix and a host part. The IP addresses of all hosts on the same link usually have the same network prefix but different host parts. This enables IP to perform route selection based on the network prefix part of the IP address of the des...
