Description
Technical field
The present invention relates to the communications field, more particularly to a kind of node communication method and communication system in PMIP domains internetwork roaming
System.
Background technology
Transmission control protocol/Internet Protocol (Transmission Control Protocol/Internet
Protocol, abbreviation TCP/IP), do not consider that the situation of topology location change, i.e. TCP/IP can occur for terminal in initial designs
Agreement does not support mobility in itself.In traditional TCP/IP network environments, IP is that internet (Internet) provides route
Function, it is all assigned with logical address, i.e. IP address to all nodes (including main frame and router), and every main frame each
An IP address is all distributed in port.IP address includes the IP of the All hosts on network prefix and host machine part, same link
Generally there are identical network prefix and different host machine parts in address.This allows nets of the IP according to the IP address of destination node
Network prefix part is routed, so that router order preserves simple prefix router, without for
Every main frame preserves an individually route.In this case, as a result of prefix router, therefore node is worked as from one
Bar link switching is to another link without changing during its IP address, and the node then can not possibly receive data on new link
Message, so as to also can not just be communicated with other nodes.
As user steeply rises to the demand of mobility and information, increasing people wishes high during movement
Internet is accessed fastly, the information being badly in need of is obtained, and completes the thing for wanting to do.Therefore, mobile Internet turns into Future Internet
Developing direction, but conventional TCP/IP agreement does not support ambulant defect so that the mobile management to terminal node turns into
The a great problem that mobile Internet is faced.
In order to solve the problems, such as mobile management, the popular mobile management technology of industry e.g., moves IP (Mobile
IP, MIP), proxy-mobile IP (Proxy MIP, PMIP) etc., support end by way of introducing fixed anchor point (Anchor)
The mobility at end.For example, MIP agreements use local shifting using home agent (Home agent, HA) as anchor point, PMIP agreements
Dynamic property anchor point (Local Mobility Anchor, LMA) is used as anchor point.
Shown in Fig. 1 is the logical architecture of PMIP agreements, including terminal node (Mobile Node, MN), peer node
(Correspondent Node, CN), Mobile Access Gateway (Mobile Access Gateway, MAG) and local mobility anchor
Point (Local MobilityAnchor, LMA).Wherein CN can be stationary nodes or mobile node, i.e., with corresponding
MAG and LMA.MAG is MN the first hop router, and its main function distributes Care-of Address when being included in MN accesses for it
(Care of Address, CoA) and MN is replaced to perform the PMIP bindings (PMIP Binding) between MN anchor point LMA.
LMA is as MN anchor point, and its main function is including on MN distribution home address (Home of Address, HoA) and processing
State PMIP bindings.Performed between MAG and LMA PMIP binding main purpose be allow both sides know other side address, i.e. on
CoA and HoA are stated, and binding relationship is stored in locally.In addition, in the binding procedure for performing PMIP, also for MN in MAG and
A bidirectional tunnel is established between LMA.What deserves to be explained is, the IP address that MN is finally got is that LMA distributes for it
HoA.In common network design, MAG is normally at the relatively low position of topology, such as the edge positioned at Metropolitan Area Network (MAN)；And LMA is then
The higher position of topology is normally at, such as saves the core of dry net.Actually often through multi-hop road between MAG and LMA
It is connected by device.
In order that the path of packet transmission is optimal, when terminal node and peer node are in same PMIP domains
Within when, it is other end of current that terminal node or peer node can use the MAG of local terminal to be got from other network elements
MAG is serviced, so as to set up a direct link between two MAG, without packet is routed into LMA again, is subtracted significantly
The detour problem of route is lacked.In order to mutually be distinguished with traditional PMIP domains, above-mentioned domain is regarded as supporting the PMIP domains of routing optimality.
The system architecture of PMIP domains intermediate node roaming supports routing optimality as shown in Fig. 2 the PMIP domains can be divided into
PMIP domains and the i.e. traditional PMIP domains in PMIP domains for not supporting routing optimality.PMIP domains for supporting routing optimality, except tradition
Network element MAG outside, comprising a mapping server (Mapping Server, MAPS), be substantially carried out node location management and
The work such as address mapping relation maintenance.Comprise in addition one or more Interworking gateway for other PMIP domains intercommunications
(InterworkingGateway, IGW), its main function includes carrying out between the PMIP domains of other support routing optimalities
Signalling exchange, while being also the data outlet between this PMIP domains and other PMIP domains, is implemented, can domain border
Multiple Interworking gateway are set, for destination node in the case of not same area, different intercommunications are selected according to route principle of optimality
Gateway.Set or a single equipment in addition, Interworking gateway can be closed with border router.In order to ensure foreign lands
Packet can reach Interworking gateway, and Interworking gateway needs HoA/ home network prefix of the overseas broadcast belonging to it.
The current PMIP network architectures are all based on terminal node in same PMIP domains under identical local mobile anchor
Movement, and the method that terminal roams into another PMIP domain from a PMIP domain is not defined also, particularly terminal
The method of the routing optimality roamed between the PMIP domains of routing optimality are supported.
