Method, mobile network and relay node for establishing mobile network tunnel

Abstract

The invention provides a method of building mobile network tube, mobile network and relay node. Said method of building mobile network tube includes: cut-in gateway which accesses network sends mobilenetwork register request to relay mode in network, said mobile network register request takes delivering address of access network provided by the cut-in gateway; said relay node transmits mobile network register request to home mobile network substitute, said mobile network register request takes delivering address of access network provided by the relay node; based on said mobile network register request, the home mobile network substitute returns the response of mobile network register request to said relay node and home mobile network substitute, mobile network tube which is meted betweenthe gateways. The technique scheme provided in the invention can be used in multiple applications such as MIPv6, PMIP.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for establishing a mobile network tunnel, a mobile network and a relay node. Background technique [0002] For a traditional fixed data communication network, the IP (Internet) protocol is widely used among communication protocols for communication at the network layer. The identification of hosts and routing addressing in the IP protocol are based on IP addresses, and IP addresses have direct location attributes, because in traditional fixed data communication networks, a directly connected network has the same network address. When the network is changed, the IP address of the host needs to match the network address of the new network, and the original IP address cannot be used anymore. Such a mechanism makes the traditional IP protocol unable to support the mobile network. With the continuous development of the network, the demand for the mobile data pa...

Problems solved by technology

[0009] From the establishment process of the MIP tunnel in the above prior art, it can be seen that the establishment of the MIP tunnel requires each mobile node to have a unique RCoA address. For the Mobile IPv4 management protocol (MIPv4, MobileIPv6 Mobility Management), IP address resources are very scarce , so the MIP tunneling method provided by the prior art is difficult to be applied to the MIPv4 network; and for the proxy mobile IP (PMIP, Porxy Mobile IP) that the network side initiates registration, due to the stateless self-configuration method in the prior art to generate the RCoA address In the process, the mobile terminal needs to perceive the particularity of the RCoA address, but the mobile terminal in PMIP cannot perceive this, so the method for establishing a MIP tunnel provided by the prior art is also difficult to apply to PMIP

Therefore, during the creation process of the present invention, the inventors found that there are at least the following problems in the prior art: the method for establishing a MIP tunnel provided by the prior art is difficult to apply to various MIP scenarios, such as MIPv4, PMIP, etc.
