Wireless communication method of LTE (Long Term Evolution) network comprising macro cell base station and home base station

Abstract

The invention comprises a wireless communication method of an LTE (Long Term Evolution) network comprising a macro cell base station and a home base station. According to the characteristics of the home base station, i.e. the characteristics of allowing public access or partially allowing the public access or only allowing to close the access of user set equipment as well as the specific circumstance of entered mobile equipment in a coverage area of the home base station, the interference of the home base station to the mobile equipment connected to the macro cell base station in a down link is reduced by adopting a mode of whether to close the user set equipment or not according to the condition whether the mobile equipment is in an activated state or not so as to improve the wireless communication quality of the mobile equipment connected to the macro cell base station in the coverage area of the home base station.

Description

technical field [0001] The invention belongs to a network wireless communication method, in particular to an LTE network wireless communication method including a macro cellular base station and a home base station. Background technique [0002] In LTE networks including macrocell base stations, deploying femtocells can effectively improve indoor signal coverage, improve user service quality, and increase network capacity. Femto base stations are small, low-power base stations that are usually used in indoor places such as homes, offices, shopping malls, and hotels. [0003] Femto base stations have the characteristics of simple access, plug and play, and user-configurable. It is precisely because of these characteristics that, on the other hand, it leads to real-time changes in the network topology. With the extensive use of femto base stations, traditional network planning The method for coordinating and solving the mutual interference between the home base station and th...

[0003] Femto base stations have the characteristics of simple access, plug and play, and user-configurable. It is precisely because of these characteristics that, on the other hand, it leads to real-time changes in the network topology. With the extensive use of femto base stations, traditional network planning The method of coordinating and solving the mutual interference between the home base station and the equipment connected to the macro cell base station is not feasible due to the huge workload

[0004] Currently for the downlink of wireless communication of a network comprising macrocell base stations and femtocells, i.e. the direction of wireless transmission from a femtocell to the coverage area of ​​the base station, most known methods involving frequency band reuse require that the femtocell is publicly accessible, But there is no way to effectively solve the problem of interference in the downlink of the femtocell to the non-closed subscriber group mobile devices connected to the macrocell base station entering the coverage area of ​​the femtocell
