Heterogeneous cellular wireless network programming scheme

Abstract

The invention relates to a network programming scheme and discloses a network programming scheme suitable for heterogeneous cellular wireless network configuration. Historical service flow distribution is used to divide a subarea and a service demanding node model is established. A link gain between different types of candidate base stations and a service demanding node is predicted. Power and bandwidths consumed by the candidate base stations when satisfying the service demanding node are determined. The candidate base stations are selected and the base stations are deployed. The sources are distributed so that load balancing between heterogeneous cellular wireless network base stations is achieved. The invention provides the network programming scheme with low cost, high performance, high precision and a balanced network load.

Description

technical field [0001] The invention relates to a network planning scheme, which relates to service flow distribution, load balancing, and a network planning scheme suitable for heterogeneous cellular wireless network architecture. Background technique [0002] The main goal of the network planning solution is to configure a series of cells in the service area at the lowest possible cost to complete the overall planning under the conditions of meeting the current and future cellular wireless service traffic requirements, cellular system capacity and interference restrictions, and service quality requirements. Seamless coverage of the area. [0003] According to the technical characteristics of each generation of cellular wireless network, the network planning scheme is different. In the second-generation cellular wireless network, the network planning scheme is generally divided into two steps: the first step is to select a subset from the candidate base station placement s...

Problems solved by technology

Due to the large transmit power and physical size of the macro base station, the geographical location of the macro base station can be installed. The macro base station that can be installed may cause some areas to be unable to be covered by the installed macro base station.

At the same time, due to the shadow fading in wireless propagation, there are some geographical areas and the path loss between the macro base station is very large, resulting in the signal strength received by users in this area is very small, and even interruption occurs

These situations cannot be handled flexibly in traditional cellular wireless networks
