Problems solved by technology

This method of reducing interference achieves the purpose of reducing interference to the micro-station by sacrificing the wireless resources of the macro-base station. Therefore, although this method can reduce interference, the resource utilization of the macro-base station is greatly affected

Embodiment Construction

[0069] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0070] refer to figure 1 , shows a flow chart of Embodiment 1 of a method for controlling a heterogeneous network according to an embodiment of the present invention, the method may include:

[0071] Step 101, when the terminal satisfies the camping condition, the micro base station sends a camping permission instruction to the terminal, so that the terminal camps on the micro base station.

[0072] In a heterogeneous network (Heterogeneous Network, HetNet), base stations serve a variety of terminal types, such as mobile phones, notebooks, vehicle-mounted computers, etc. These terminals must first reside in the heterogeneous network to receive services from the heterogeneous network. Under a certain base statio...

Abstract

The invention provides a heterogeneous network control method and a base station. The control method includes the steps that when terminals meet resident conditions, a micro base station sends resident permission instructions to the terminals so as to enable the terminals to reside in the micro base station; the micro base station receives service requests sent by the terminals and distributes wireless resources unoccupied by a macro base station to the terminals according to the types of the service requests. The main reason that users of the macro base station interfere the micro base station is that the users of the macro base station and users of the micro base station occupy the same wireless resources, and therefore the wireless resources distributed to the terminals by the micro base station are the wireless resources unoccupied by the macro base station, the problem of co-channel interference is avoided, and the resource utilization rate of the macro base station will not be influenced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a control method and a base station of a heterogeneous network. Background technique [0002] With the rapid development of mobile communication technology, people have higher and higher requirements for communication network. In order to meet the user's higher demand for network experience, a heterogeneous network (Heterogeneous Network, HetNet) is introduced into the cellular network to improve spectrum resources. purpose of utilization. HetNet refers to the deployment of several low-power nodes (ie, micro base stations) within the coverage area of ​​a macro base station in a traditional cellular network to form a heterogeneous system of different node types with the same coverage. [0003] Since the macro base station and the micro base station in the HetNet network occupy the same wireless resources, the edge users of the macro base station will generate st...
