Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The purpose of the present invention is to propose a MIPv6 vertical handover control method under a multi-system network environment with overlapping coverage, to support the MN's measurement, analysis and decision-making process for different system access network performance during the handover process, so as to solve the problem of MN's overlapping coverage. The selection of the optimal network in the multi-standard network environment.

[0031] The method specifically includes the following steps:

[0032] A. The MN regularly detects each network interface, and when a new network signal set is detected, the candidate network screening process is triggered;

[0033] B. MN performs candidate network pre-selection according to the network screening rules in the user configuration file;

[0034] C. MN sends "candidate network perform...

Abstract

The MIPv6 vertical switch control method in multi-system network environment comprises: setting independent local management unit in every sub-network to measure data for network performance; evaluating the candidate network synthesizing all performance index and user preference by the switch decision module on mobile node; selecting the optimal network. This invention solves the optimal selection problem.

Description

technical field [0001] The present invention belongs to the field of mobile IP, and specifically, proposes a MIPv6 vertical handover architecture under a multi-standard network environment with overlapping coverage, through local management unit (LMU) and mobile node (MN) handover decision-making and handover management ( HFDM) module to support the MN to select the optimal network for handover, the LMU mainly provides the measurement of network side performance in the vertical handover, the MN handover decision and handover management module mainly selects the optimal network for handover according to the corresponding parameter indicators. Background technique [0002] Wireless and mobile networks are ubiquitous, providing users with communication services everywhere. Existing wireless and mobile networks are different in terms of coverage, access capabilities, address ranges, and mobile support, which increases network heterogeneity while providing users with rich access ...
