Problems solved by technology

[0014] In order to overcome the problem that the vertical handover performance of the existing TPMIPv6 protocol is affected by the dwell time of the MN in the signal overlap area, the present invention proposes a TPMIPv6 vertical handover method based on a stable address, i.e. ETPMIPv6 (enhanced TPMIPv6)

Embodiment Construction

[0035] A PMIPv6 vertical handover method provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] In general, this application proposes a TPMIPv6 handover method based on stable addresses, that is, ETPMIPv6, wherein the stable address refers to the address that can continuously receive data packets in the MN during the vertical handover, using IP steady Indicates that the address participating in the switch is called the switch address, and the IP handoff express. The method of the present application generally includes that the MN receives data packets through its own stable address instead of the handover address during the vertical handover. In addition, the interface that participates in handover is called a handover interface and is represented by IFh, and the interface that does not participate in handover is called a non-handover interface and is represented by IFs.

Abstract

The invention provides a proxy mobile IPv6 (PMIPv6) vertical switching method. The method comprises the following step: in the vertical switching period, mobile node uses the own stable address to replace switching address and receive data packet, wherein the stable address refers to the address where mobile node receives data packet continuously in the vertical switching period, and the switching address refers to the address involved in switching. Compared with the TPMIPv6 protocol, the method of the method can reduce the switch delay and packet loss ratio of data in the switching process of the mobile node in the mobile access gateway.

Description

technical field [0001] The present invention relates to network management technology, more specifically, the present invention relates to a PMIPv6 vertical switching method. Background technique [0002] Proxy Mobile IPv6 (PMIPv6) is a new generation of mobility management protocol proposed by the IETF NETLMM working group in August 2008. Compared with Mobile IPv6 (MIPv6), PMIPv6 does not require Mobile Node (MN) to participate in mobility management, and has a smaller handover delay. [0003] Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG) are two key network entities in PMIPv6 deployment. As the topological anchor point of the MN's Home Network Prefix (HNP), the LMA is responsible for maintaining the reachability status of the MN. The MAG is responsible for detecting the mobile state of the MN, and judging whether the MN accesses or leaves the wireless link maintained by the MAG. When the MN accesses the wireless link maintained by the MAG, the MAG initiate...
