Embodiment

[0043] figure 1 It is a schematic diagram of the network structure of the macrocell-femtocell in the present invention;

[0044] In this example, figure 1 The shown network is a downlink of a two-layer network structure, and the network is composed of macrocells and femtocells, which share the same frequency segment. The network includes 4 macro base stations (MacrocellBaseStation, MBS for short), and each MBS uses a directional antenna, that is, an MBS sector antenna, to cover 3 sectors. A building where a femtocell base station (FBS) is deployed is either located at the center of the macro cell or at the edge of the macro cell, where the shaded part represents the edge of the macro cell, and the other parts represent the center of the macro cell.

[0045] Indoors, users served by the FBS are called femtocell users, denoted by FUE. In an outdoor environment, users served by the MBS are called macro cell users, denoted by MUE. FBS is randomly deployed in each building unit...

Abstract

The present invention discloses a method for obtaining Femtocell coverage probability. The position of Femtocell base station is modeled as randomness and obeys Poisson point distribution. On this basis, the coverage is calculated according to the position of the macro cell where the Femtocell base station is located. probability. Due to the use of random geometric mathematical analysis tools in the calculation process and the consideration of the impact of environmental factors on coverage performance, the Femtocell coverage probability can be obtained more accurately, providing an effective and accurate method for network coverage performance analysis and comparison.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically relates to a method for obtaining Femtocell coverage probability. Background technique [0002] A femtocell is a femtocell base station, also known as a home base station or a 3G access point, and is an important part of a heterogeneous network. Femtocell base stations have the characteristics of small size, light weight, low cost, low transmission power, automatic configuration, automatic network planning, plug and play, etc., can be installed by non-professional users, and can provide high-quality voice and data services. By installing a femtocell base station, users in the cell can use any existing network to access the core network of the cell, and the short communication distance from the user equipment to the home base station realizes user communication. The Femtocell base station can improve the capacity of the residential network very well without significant...
