Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] The present invention proposes a new method for realizing user mobility based on the separation technology of identity identification and location, which separates the dual attributes of identity and location of IP addresses, and the addresses assigned to mobile users only identify the identity attributes of mobile users, and no longer It has a location attribute, which is used to establish a TCP connection, and the address is represented by an Endpoint Identifiers (EID for short); while the address allocated by the network part only identifies the location attribute, and no longer represents the user's identity attribute, the address is represented by a routing A location (Routing Locator, RL...

Abstract

A method for realizing user mobility is disclosed by the present invention. In the method, an address is assigned for a mobile node, and a Transmission Control Protocol (TCP) connection of the mobile node is established according to the address; the address only identifies the mobile node identity attribute, which is showed by an Endhost Identity (EID) address; a network node encapsulates an IP message of the mobile node; the address of the IP message encapsulated only has location attribute, which is showed by a Routing Locator (RLOC) address. The method includes that a boundary tunnel router receives the IP message; the boundary tunnel router finds the RLOC address corresponding to the EID address of the IP message locally; the boundary tunnel router encapsulates the IP message with the RLOC address; the boundary tunnel router sends the IP message after encapsulation. According to the present invention, the user mobility can be realized simply.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for realizing user mobility. Background technique [0002] With the development of the network, there are more and more demands for user mobility. However, the design of the Internet is based on the fixed (wired) access environment, and does not take into account the large number of mobile users. Therefore, how to solve the situation of user mobility in the Internet is a hot spot of current research. [0003] At present, there are MIPv4, MIPv6, PMIPv6 and other protocols for user mobility solutions in the Internet, but most of these protocols have shortcomings. MIPv4 and MIPv6 are host-based solutions, which require certain changes to the host, and can only be used IPv4 network and IPv6 network, MIPv4 and MIPv6 also have serious triangular routing problems. For the PMIPv6 protocol, the implementation of the protocol is relatively complicated, and it can only be used i...
