Address switching method and device

Abstract

The embodiment of the invention discloses an address switching method and a device. The address switching method comprises the following steps that: a first terminal adopts a first IP address corresponding to a first terminal label to communicate with a second terminal; the first terminal transmits at least one IP address in other IP addresses corresponding to the obtained first terminal label to the second terminal, and a message transmitted by the second terminal is received by the first IP address and the IP address transmitted to the second terminal; and the first terminal carries out address switching and adopts a second IP address in the IP address transmitted to the second terminal to communicate with the second terminal. The technical scheme provided by the embodiment of the invention decreases the loss rate of a data packet in the terminal address switching process effectively.

Description

technical field The present invention relates to the field of communication technology, in particular to an address switching method and device. Background technique With the development of communication and computer technology, terminals are more and more mobile. In the traditional TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol), an assumed situation is that the geographical location of the communication terminal is relatively fixed, and the IP address of the terminal represents the topological position of the terminal in the network. , which also represents the identity of the terminal. The dual role of the IP address leads to the inability to maintain the upper-layer communication status when the terminal moves, which is not suitable for the development of terminal mobility. In order to solve the above problems, it is a better solution to separate the identification function and the location function of the term...

AI Technical Summary

Problems solved by technology

The disadvantage of the above-mentioned address switching solution in the prior art is that data packets will be lost during the address switching process of the mobile terminal

For example, during the address switching process of the mobile terminal, the original IP address used by the mobile terminal is no longer available, but the peer communication terminal still sends data packets with this address as the target address, which will cause data packet loss
