Abstract

The invention embodiment relates to a message error detection method, equipment and a system for message error detection and processing. The method comprises the following steps: receiving a message retransmitted by a mobile IP tunnel; verifying the message, and sending error indication information to an opposite network element of the mobile IP tunnel if verification fails. The system comprises message error detection equipment and message error processing equipment, wherein the message error detection equipment is used for verifying the received message retransmitted by the mobile IP tunneland sending the error indication information to the message error processing equipment when the verification fails, and the message error processing equipment is used for searching corresponding mobile IP registration binding according to the received error indication information, and deleting data connection information corresponding to the searched mobile IP registration binding or updating thedata connection information corresponding to the mobile IP registration binding.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a message error detection method, a message error processing device and a message error detection and processing system. Background technique [0002] The next generation mobile packet network (EPS, Evolved Packet System) can choose mobile IP as its mobility management protocol. That is to say, with the growing demand for terminal mobility, mobile IP technology has been created on the basis of common IP technology. [0003] In the current technical solution, the mobile node is anchored to the anchor point through the access gateway, and the mobile node or the access gateway registers with the anchor point to bind the care-of address (CoA, Care-of Address) and home address (HoA, Home Address) , establishing a mobile IP tunnel from the mobile node to the anchor point. After that, the mobile node can send and receive messages through the anchor point, including sending messages t...
