Method for converging heterogeneous networks based on dynamic load transfer

Abstract

The invention discloses a method for converging heterogeneous networks based on dynamic load transfer. The method comprises the following steps that: firstly, mobile terminals in the heterogeneous networks periodically report terminal-side information; secondly, a base station and a wireless access point make a joint decision for a target mobile terminal; and finally, with cooperation of the base station and the wireless access point, the target mobile terminal finishes a vertical switching process, evaluates the performance of the heterogeneous networks, and calls a dynamic load transfer scheme in real time according to an evaluation result so as to realize dynamic balance of network loads. By adoption of the method for converging the heterogeneous networks based on the dynamic load transfer, the heterogeneous networks can be effectively converged by introducing a priority-based dynamic load transfer mechanism; by designing an access selection policy of a user terminal and using a dynamic closed-loop feedback mechanism, wireless resources in the heterogeneous networks are effectively utilized; different wireless access technologies are integrated into a unified network environment; and an important reference value is provided for research of a heterogeneous wireless network convergence technology.

Problems solved by technology

The basic starting point of traditional wireless resource management is to allocate and dynamically adjust the available resources of the wireless transmission part and the network in the case of uneven distribution of network user terminals and fluctuating channel characteristics due to channel fading and interference, so as to maximize the improvement of the wireless network. resource utilization, prevent network congestion and keep the signaling load as small as possible, and provide reliable service quality assurance for wireless user terminals in the network. However, in terms of specific wireless resource management strategies, there is no clear definition for heterogeneous converged networks. Modeling, resulting in many deficiencies in resource allocation strategies and management performance, unable to deal with the heterogeneity and transient nature of wireless networks in real time
