A Heterogeneous Wireless Network Resource Allocation Method for Handling Emergency Services

Abstract

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. In the process of allocating bandwidth resources, the present invention provides services of different qualities to different businesses, especially for urgent business needs, requiring the wireless access network to firstly meet the requirements and provide access services for them. In the process of bandwidth resource allocation, if the emergency service is a CBR service, the fixed bandwidth demand value must be allocated for this type of service; if the emergency service is a VBR service, the bandwidth resource allocated for this type of service only needs to be within the range of its bandwidth requirements. While guaranteeing urgent business needs, corresponding guarantee mechanisms are also adopted for the allocation of bandwidth resources for common businesses. The present invention can accommodate more common service bandwidth requests while guaranteeing that emergency services can obtain bandwidth resource allocation in priority, thereby maximizing the utility of the heterogeneous wireless network system.

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.
