Problems solved by technology

Although LISP_MN and various derivative technologies can well support terminal mobility, it requires two MS lookups and two data encapsulations during the entire communication process, and requires modification of the existing terminal protocol stack

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 Shown is an identification network mobile access system, including the following network elements:

[0034] The edge identification network includes a mobile node MN and a peer communication node CN, and both MN and CN use the endpoint identification address EID for addressing;

[0035] The core network includes a mapping server MS, the MS uses the routing locator address RLOC addressing, and the MS maintains the identification mapping table;

[0036]The edge router XTR bridges the edge identification network and the core network, including the edge router XTR-B in the current roaming position of the mobile node, the edge router XTR-A in the previous roaming position of the mobile node, and the edge router XTR-Cor to which the peer communication node belongs; the XTR connection The port of the identification network is addressed by EID, and th...

Abstract

The invention discloses a marked net mobile access method. The method comprises the following steps that: a mobile node judges whether or not movement occurs through router notice information of an edge router; if movement occurs, the mobile node initiates registration to the edge router, and the edge router assists the mobile node in registering to a mapping server as an agent; the mapping server pushes new mapping information to a previous edge router of the mobile node; data transmitted to the mobile node by an opposite-end communication node through the edge router to which the opposite-end communication node accesses is transmitted to a previous edge router of the mobile node, and the previous edge router re-encapsulates the data and forwards the re-encapsulated data to a current edge router of the mobile node; the previous edge router pushes the new mapping information of the mobile node to an edge router where the opposite-end communication node is positioned through the mapping server; data subsequently transmitted by the opposite-end communication node is directly transmitted to the current edge router in the edge router of the opposite-end communication node according to the new mapping information; and data transmitted to the opposite-end communication node by the mobile node is transmitted normally through the accessed edge router.

Description

technical field [0001] The invention relates to a mobile access method of an identification network, which belongs to communication network technology for mobility management and access of a mobile terminal in an identification network that separates identity and location at the network level. Background technique [0002] In the traditional IP network, mobile IP (MIP) technology is usually used to solve the mobile access problem of the terminal at the network layer. In MIP, home agent and foreign agent are introduced, and the IP address of the terminal does not change with the location. When the terminal roams in the network, it can keep the communication uninterrupted while the IP address does not change. The data between terminals in the network Communication is encapsulated and sent using tunnel technology. Mobile IP is simple to implement and relatively easy to deploy, but triangular routing is generated during data communication, which increases the delay of data tran...
