Heterogeneous wireless network resource allocating method for processing emergency businesses

Abstract

The invention belongs to the technical field of wireless networks, and particularly relates to a heterogeneous wireless network resource allocating method for processing emergency businesses. The method includes that in the process of distributing bandwidth resources, services different in quality are provided for different businesses, especially for emergency business needs for access to wireless networks, requirements are met preferably, and access services are provided; in the process of allocating bandwidth resources, if the emergency businesses are CBR (constant bit rate) businesses, fixed bandwidth need values must be distributed to the CBR businesses; if the emergency businesses are VBR (variable bit rate) businesses, bandwidth resources distributed to the VBR businesses need to be within a bandwidth need range. On the premise that emergency business needs are guaranteed, corresponding guarantee mechanisms are adopted for bandwidth resource allocating of common businesses. By using the method, the emergency businesses are ensured to acquire bandwidth resource allocating preferably, and more common business bandwidth requests can be contained, so that a heterogeneous wireless network system realizes maximum efficiency.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, and in particular relates to a method for allocating resources of a heterogeneous wireless network for processing emergency services. Background technique [0002] The traditional wireless resource management and allocation algorithms work independently to provide service quality assurance for wireless user terminals in the network. The heterogeneous wireless network refers to a network system with multiple wireless access technologies. Common access networks include 3G / 4G cellular mobile communication networks, IEEE802 series wireless local area networks, and wireless metropolitan area networks. Different access networks differ and complement each other in terms of coverage, transmission rate, bandwidth, and price. Therefore, how to coordinate wireless resources between networks and optimize wireless resource utilization has become a research hotspot in heterogeneous wireless network r...

Problems solved by technology

[0005] This resource allocation method uniformly allocates bandwidth resources in a heterogeneous network environment for terminal users who generate two common services, so as to ensure that the overall benefit of the heterogeneous network reaches a higher level, but in the actual heterogeneous wireless network environment, not only There are a variety of common services, and there will also be emergency services such as 110 alarm, 119 fire alarm and 120 ambulance. Such urgent business needs must be prioritized to ensure the safety of people's lives and property and even national security.
