Problems solved by technology

[0007] Since the data sent to MR needs to be encapsulated every time it passes through an HA, multiple encapsulations will occur in the nested mobile network, which increases the network load

Embodiment 1

[0060] The communication method between mobile network nodes provided by the embodiment of the present invention, such as figure 1 As shown, the method steps include:

[0061] S101. The top level mobile router (Top Level Mobile Router, TLMR) receives the registration information of the mobile router, sends the registration information to the home agent of the mobile router, and updates its own child mobile router information list;

[0062] S102. The first-layer mobile router receives the request for establishing a bidirectional tunnel, and establishes a two-way tunnel with the requester, wherein the request for establishing a bidirectional tunnel is generated according to the location information of the first-layer mobile router;

[0063] S103. The first-layer mobile router receives data from the data source node through a bidirectional tunnel, and sends the data to the data sink node by using its own sub-mobile router information list.

[0064] Here, the first-tier mobile ro...

Embodiment 2

[0069] The communication method between mobile network nodes provided by the embodiment of the present invention is described by taking communication between a node in a NEMO (Network Mobility, network mobility) domain and a common node as an example.

[0070] Before the communication between nodes, the first thing to do is the MR registration process, such as figure 2 As shown, when MR3 to which the data destination node LFN1 (Local Fixed Node, local fixed node) belongs is connected to the domain of MR2, MR 3 sends registration information to MR2, wherein the registration information includes: the home address HoA of MR 3, MR 3’s care-of address CoA, the HoA and CoA of the child MR in the MR 3 domain, request the allocation of CoA and inform MR2 of its relevant information, MR2 updates its child MR information list, and notifies the upper layer MR of its changes, and finally reaches MR1, namely TLMR , TLMR forwards the registration information of MR3 to the corresponding HA ...

Embodiment 3

[0079] The communication method between mobile network nodes provided by the embodiment of the present invention is described by taking the communication between nodes located in two nested NEMO domains as an example.

[0080] The pre-communication registration process is similar to that in Embodiment 1, and will not be repeated here.

[0081] In the embodiment of the present invention, the communication between the data source node LFN1 located in the MR1 domain and the data sink node LFN2 located in the MR4 domain is taken as an example. The destination address of the data sent by LFN1 to LFN2 is the IP address of LFN2, such as Figure 4 Shown:

[0082] The data sent by LFN1 to LFN2 is forwarded by MR1 (TLMR of LFN1), and first sent to the home agent HA6 of MR6 to which LFN2 belongs;

[0083] After HA6 receives the data, it extracts the source address of the data, that is, CoA1 of MR1, and searches its binding cache list at the same time, and finds that the best forwarding ...

Abstract

The embodiment of the invention provides a method, equipment and a system for communication among mobile network nodes, and relates to the field of communication. The method, the equipment and the system can reduce network load and improve access efficiency. For solving the problems, the invention adopts a scheme that: a first layer mobile router receives registration information of a mobile router, sends the registration information to a hometown agency of the mobile router, and updates information lists of a sub mobile router; the first layer mobile router receives a request for building a two-way tunnel and builds the two-way tunnel with a requesting party, wherein the request for building the two-way tunnel is generated according to the positional information of the first layer mobilerouter; and the first layer mobile router receives data from data source nodes by the two-way tunnel and sends the data to data destination nodes by using the information list of the sub mobile router. The method, the equipment and the system are used for communication among the mobile network nodes.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method, device and system between mobile network nodes. Background technique [0002] With the rapid development of the Internet, the access form of fixed location and fixed method can no longer meet people's daily needs, and the ubiquitous mobile access to the Internet anytime, anywhere has become the main trend of network evolution. At present, a network access solution supported by terminal mobility is provided. In this solution, the access address of MN (Mobile Node, mobile terminal) is extended to HoA (Home Address, home address) and CoA (Care of Address, handover address). During the moving process of the MN, the CoA is obtained by the router accessing the network, while keeping its HoA unchanged. When the MN moves to the external network, a functional entity called HA (Home Agent) of the home network is used to intercept the data packet whose target address is t...
